EXPLANATORY NOTE

As previously disclosed, on January 23, 2023, Rockley Photonics Holdings Limited (the “Company”) filed a voluntary petition for relief under chapter 11 of title 11 of the United States Code in the United States Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”) to implement a “pre-packaged” plan of reorganization (the “Plan”) in order to facilitate the restructuring of the Company. On January 24, 2023, the Company’s ordinary shares, $0.000004026575398 par value per share, trading symbol “RKLY”, and its public warrants, with each whole warrant then exercisable for one ordinary share at an exercise price of $11.50 per share, trading symbol “RKLY.WS” were suspended from trading on the New York Stock Exchange (the “NYSE”). On February 21, 2023, the Company’s ordinary shares and its public warrants were delisted from the NYSE. Accordingly, the Company does not have any securities registered pursuant to Section 12(b) of the Securities Exchange Act of 1934 (the “Exchange Act”).

On March 10, 2023, the Bankruptcy Court entered an order (i) approving the adequacy of the Company’s disclosure statement and (ii) confirming the Plan (the “Confirmation Order”), attached hereto as Exhibit 2.1. The Plan became effective on March 14, 2023 (the “Effective Date”). Upon the filing of this Annual Report on Form 10-K, the Company intends to file a Form 15 to suspend its periodic reporting obligations under Sections 12(g) and 15(d) of the Exchange Act.

On or about March 14, 2023, in connection with the Plan, the Registrant’s ordinary shares were cancelled and no ordinary shares are outstanding as of the date of this annual report on Form 10-K. Except as provided in the Plan, all other equity, debt, convertible equity, and convertible debt of any kind issued by the Company were cancelled and are no longer outstanding as of the date of this annual report on Form 10-K. It is anticipated that the Company will be dissolved following the closing of the bankruptcy case in accordance with the Plan and Cayman law.

Company Overview

We have developed a comprehensive range of silicon photonics technologies that have both the power and the flexibility to support a wide range of potential applications. Our silicon-photonics platform will incorporate several key components to support these solutions, including photonic integrated circuits and associated modules, sensors, and end-to-end solutions. We expect that our immediate focus over the next two years will be on developing and commercializing our products for incorporation in consumer wearables, medical devices, and dedicated solutions for the healthcare market.

The summation of our technologies and manufacturing expertise is Rockley’s “cohesive end-to-end platform.” Our end-to-end platform encompasses photonic integrated circuits (“PICs”) in silicon with integrated III-V devices (devices incorporating certain conductor elements that offer superior electronic properties, such as lasers), application-specific electronic integrated circuits (“ASICs”), and photonic and electronic co-packaging, which are all supported by and coupled with biosensing algorithms, AI, cloud analytics, firmware/software, system architecture, and hardware design.

With this unique sensing platform, we believe we can reshape several important markets of the healthcare sector such as consumer wellness, long term health trend monitoring, patient monitoring, early disease detection, nutrition management and the treatment of certain chronic diseases. Our biosensing platform is designed to enable multiple applications using our non-invasive, continuous, multi-modal biomarker monitoring capabilities. Our target biomarkers for consumer healthcare include lactate, alcohol, glucose (indicator), hydration, blood pressure, blood oxygen and core body temperature, among others.

Our end-to-end solutions include hardware with the potential to detect multiple biomarkers, related algorithms, cloud-based analytics and artificial intelligence (“AI”). We have shipped early engineering samples to some of our customers to support research and development efforts.

Our platform has been built upon our silicon photonics technology, which enables highly advanced sensor performance, power, resolution, and formfactor. This technology has the potential to allow monitoring devices, currently the size of clinical laboratory machines, to be miniaturized to the size of a wearable device. We believe that this miniaturization capability has the potential to unlock additional applications in consumer electronics and medical devices. Our technology is built on over 260 patents and over nine years of product development.

We have established a manufacturing ecosystem based upon our wholly-owned, proprietary processes in several areas. We believe that this manufacturing ecosystem will support rapid scalability.

As we do not currently have any products in commercial production, our current customer relationships are in the following stages: (a) customers with whom we are “engaged,” or in discussions with, regarding potential product features for incorporation into such customer’s end products, or (b) customers with whom we are “contracted,” where we have non-binding MOUs or development and supply agreements. These MOUs and development and supply agreements provide a general framework for our transactions with the customer and typically provide that we will develop and deliver new products meeting the customer’s specifications. There are no binding purchase commitments under our MOUs and supply agreements. We currently anticipate that sales of our products will be primarily made pursuant to standard purchase orders, which orders may be cancelled, reduced, changed, or rescheduled with little or no notice or penalty.

Product Applications and Development Status

We believe that our innovative and differentiated silicon photonics platform positions us to make photonics-based solutions increasingly pervasive, while unlocking previously unaddressed applications. Consequently, we believe that the potential applications for our technology will be wide-ranging. Leveraging the flexibility and power of our innovative silicon photonics platform, we believe that we are positioned to become a leading supplier of end-to-end solutions (including integrated optical components, algorithms, data analytics, and AI) for dynamic, high-growth market sectors, including consumer sensors, medtech and healthcare.

LOGO

To date, we have been engaged in developing customer-specific designs of our silicon photonics chipsets and modules for incorporation into our consumer electronics customers’ end products. We are working with leading customers in the medtech market to deliver a standalone wrist-wearable product for targeted use cases. In parallel, we are shaping and developing our own standard offerings that could have different shapes and form factors. Currently, we do not have any of our own end products in commercial production.

Healthcare: Consumer Wearables

We believe the high-density optical integration capabilities of our platform can personalize healthcare monitoring of multiple biomarkers and can significantly improve how individuals track and monitor their health and well-being. Our VitalSpex^™ biomarker sensing platform will address the consumer wearable market. Further, as part of our product offering, we believe that our cloud-based analytics and AI platform will offer further insight by leveraging data collected through our unique and broad sensing platform and will provide meaningful and actionable insights to end users. Our plans for the VitalSpex^™ biomarker sensing platform include a Baseline module and a Pro module, each of which will have a wide array of current and potential applications, as shown in the figure below. Depending on the needs of each customer and market trends, multiple generations of products could be built on each of these platforms addressing different set of biomarkers, form factors, performance specifications, and potential use cases.

Figure 3: Targeted biomarker sensing capabilities

LOGO

These products are intended to address the needs of the consumer market and will provide information about general health and wellness. (i.e., they do not require regulatory approval for offered applications and end uses.) As we move forward, we intend to monitor and comply with regulations to the extent they become applicable to us, including any requirements for clearance by the U.S. Food and Drug Administration (FDA) and/or other regulatory bodies.

Healthcare: Medical Devices

Our Bioptx^™ healthcare sensing platform will address the medical and professional healthcare market. We plan to incorporate our biomarker sensing technology into existing devices (such as medical patches, wearable bands, and other monitoring devices) to provide additional biomarker sensing capabilities not currently available to consumers. Also, as part of the Bioptx product offering, we intend to deliver a complete standalone finished product with targeted use cases for healthcare and health monitoring.

We believe that these product offerings will enhance point-of-care and remote monitoring and will have the potential to ultimately transform and disrupt the delivery of patient monitoring and healthcare. In the medical device space, we currently anticipate that we will develop two types of devices: an advisory device that will not need regulatory clearance and a clinical device that will need regulatory clearance from the FDA or other regulatory bodies.

These products are still under development. Even though there can be no assurance that these product development efforts will succeed or that, even if developed, these products will be approved by regulators or achieve widespread market acceptance, we believe that there are significant market opportunities in addition to our consumer wearables applications.

Data Communications: Transceiver Chipsets and Co-Packaged Optics

Data centers, which are the nerve centers of the digital economy, require interconnected communications for which we believe our datacom chipset technology offers several advantages. Business, entertainment, vital medical research, and other aspects of daily life are in many ways connected to hyperscale data centers, which in turn rely on cost-effective, power-efficient optical communication links. Whether incorporated in pluggable optical transceiver modules or in co-packaged optics, we believe hyperscale data centers will benefit from the unique advantages that our silicon photonics platform has to offer. Furthermore, we believe our go-to-market approach of partnering with Transceiver manufacturers and Switch/Networking equipment OEM companies has economic benefits over participating directly in this margin-sensitive market. By selling/licensing our assets/technology, we offer the third party the opportunity to create an economically compelling solution without any margin stacking while Rockley can keep expenses low/minimal and benefit from upfront/ongoing fees. Note that given Jiangsu Hengtong Optic-Electric Co., Ltd. (a shareholder in our joint venture partner) was placed on the “Entity List” by the U.S. Bureau of Industry and Security (BIS) of the U.S. Department of Commerce in December 2021, we have widened our potential partner network significantly and are evaluating various options for this business.

Other Applications

We believe that our silicon photonic platform is suited for delivering the sensing capabilities needed for machine perception and interrogation at depth, which has become increasingly necessary in industrial automation, robotic vision (including surgical applications), safety, and other autonomous applications. Finely tuned light, delivered through a PIC via a free-space aperture or fiber optic interconnect with accompanying detection receiver capabilities, enables substantially better capabilities than previously available technology, such as frequency modulated continuous wave (“FMCW”) LiDAR for automotive safety solutions, as well as future autonomous vehicle offerings. Our team has extensive experience in the design of PICs for use in the LiDAR domain, and we have prototyped the key components of the system and demonstrated their superior performance. Although we believe the inflection point for LiDAR and the automotive market may be approaching, we plan to leverage our core technology readiness and economies of scale from our consumer business to position ourselves for this potential market opportunity.

Market Opportunity

Health and Wellness

There is growing demand for miniaturized, wearable solutions that offer an affordable way to provide key insights into a person’s health and well-being, outside the clinical environment. Delivering relevant insights will require non-invasive, continuous, real-time sensing and measurement of multiple biomarkers, coupled with advanced analytics to interpret the data. We believe that this demand is driven and will continue to be driven by two major market and secular trends:

•

Consumer health and well-being awareness. While there is an existing market for athletes in training and for highly active and health-conscious users, there has been an increasing global consumer focus on preventative healthcare, with users desiring greater control and visibility over their own health and well-being. In parallel, amid the proliferation of wearable technologies with emerging health monitoring capabilities, there is greater demand for more sophisticated and comprehensive sensing technology that can measure and track a broad range of conditions and biomarkers. Generating a holistic view of the human body through access to multiple biomarkers will enable a more sophisticated ability to monitor and track general trends of changing health conditions. This has the potential to help physicians identify health conditions and possible disease states earlier and allow for more affordable prevention measures and effective patient treatment, perhaps long before requiring aggressive disease management. More recently, COVID-19 has had a profound impact on the way consumers perceive their need for “at-home” monitoring solutions.

•

Treatment of chronic conditions and disease care. With increased life expectancies, a growing number of chronic conditions and diseases has placed a strain on healthcare systems. Furthermore, non-invasive monitoring solutions for chronic conditions have historically been costly and available only in a medical facility. With our potential for delivering individual non-invasive wearable monitoring solutions, we believe that we have a great opportunity to impact patients’ compliance with healthcare guidance and subsequent efficient treatment of patients, which will lead to better quality of life and drastic reductions in the overall cost of healthcare. Non-invasive, continuous monitoring also has the potential to detect and possibly prevent chronic conditions and diseases at a much earlier stage, resulting in reduced overall healthcare cost.

We believe that existing monitoring and sensing technologies are not capable of delivering on the needs of consumers and healthcare professionals. Meeting these needs require solutions that provide access to a broad range of biomarkers non-invasively; that can be miniaturized and operate with power low enough to be integrated into consumer wearables, medical patches, and other compact form factors; and that can scale cost effectively to high volumes. We believe that our silicon photonics-based platform is poised to serve at the confluence of the above two market and secular trends.

Beyond these opportunities, we believe there may be significant potential for us in the field of genomics. As the field of genomics grows, as shown in the development of personalized medicines and treatment, the value and effectiveness are enhanced when genomic information is combined and processed along with continuous biomarker monitoring for the users. We believe this emerging field could play to the strengths of our platform and potentially represents a high-value growth opportunity for the future.

Data Communications

Datacenter operators continue to build and upgrade their datacenter infrastructure to meet the continuing growth in public, private, and hybrid cloud capacity. As these datacenters rely heavily on fiber optics to interconnect compute, storage, accelerators and other resources, this trend is reflected with substantial growth in demand in the high-speed Ethernet optics. The market segment that we are primarily targeting comprises 400Gb/s and 800Gb/s. We believe our silicon photonics platform is well positioned to address this market with highly integrated Si PICs and class leading III-V technology to implement the optical functionality required for such transceiver modules. We believe that our platform will provide a substantial cost advantage over conventional discrete-optics-based solutions, as well as over competing integrated photonics solutions due to our platform’s inherent benefits.

Competitive Advantages

We believe our silicon photonics solutions and technology offer the following key healthcare monitoring benefits:

•

Superior sensing performance. Our silicon photonics-based spectrometer chip provides up to one million times higher resolution, approximately one thousand times higher accuracy, and approximately one hundred times broader spectral range than existing LED-based solutions, based on product analysis undertaken by Rockley comparing the Rockley silicon photonics-based spectrometer chip to existing LED-based solutions. We believe that our unique silicon photonics technology and the entire product ecosystem we are developing will make our end-to-end offerings in the health and wellness domain difficult to replicate. Current optical-based sensing solutions rely on LED-based sensing (PPG signals for SpO2, heart rate, heart rate variability, breath rate, and blood pressure). However, there are many biomarkers present in the body (such as in blood or interstitial fluid) that are not detectable in the visible LED range. We believe that our silicon photonics technology delivers several ingredients that will be required to bring a powerful and meaningful product into the healthcare market: the accuracy and width of our wavelength span in the infrared spectrum, the capability of our silicon photonics solutions to integrate many wavelengths, and the high signal-to-noise ratio (“SNR”) generated by our chips.

•

Flexible platform architecture. We have designed our platform from the ground up and, leveraging our team’s extensive experience, have developed a highly flexible platform architecture. As a result, we believe our innovative platform architecture will allow us to easily configure core building blocks to produce a wide range of functional components and modules for high-volume applications across a broad range of market sectors.

•

Differentiated biomarker sensing algorithms and analytics. Our biomarker detection algorithms are optimized for our unique and optimized hardware technology platform. We believe that the data analytics and biomarker processing capabilities of our AI / cloud offering will further expand our ability to offer additional insights into a person’s health.

•

Deep understanding of market opportunity and customer priorities. We are developing many applications and systems with our silicon photonics solutions that are driven by industry leaders in the consumer sensors, healthcare, and data communications markets. Through our established relationships with industry leaders, we have consistently demonstrated our ability to address their technological challenges. As a result, we have signed memoranda of understanding and have contracted with several industry leaders in wearable consumer technology to establish product specifications and desirable features. We believe we are well-positioned to develop high-volume optical sensing modules and algorithms for their emerging architectures. We have ongoing, collaborative discussions with consumer wearables, healthcare, and communication companies and original equipment manufacturers (“OEM”) and module and component vendors to address their next-generation product offering to end users.

•

Fabless, scalable business model with manufacturing process expertise and ownership. We plan to operate in a fabless business model by using third-party foundries to manufacture and test our products. We believe that outsourcing our product manufacturing and test processes and procedures simplifies our operations, significantly reduces capital commitments, and provides greater flexibility to respond to new market opportunities and scale with our customer demand. We also believe this approach will allow us to invest and focus our resources on proprietary process development and sales and marketing efforts.

•

Highly differentiated manufacturing process. Our manufacturing processes in several key areas (PICs, III-V actives, Integration) are unique and well-suited to meeting our customers’ economic and performance needs for their applications. In particular, we believe our silicon PIC process on multi-micron thick Silicon-On-Insulator (“SOI”) is a key differentiator. Our manufacturing processes utilize standard semiconductor manufacturing equipment but are optimized for photonics performance through incorporating innovative features to facilitate easier integration and packaging.

•

Extensive intellectual property portfolio. We believe our extensive intellectual property provides us with a significant competitive advantage. Our know-how is based on over 30 years of leadership in the development and commercialization of silicon photonics, and we have established strong and deep technical foundations and expertise for high-volume product delivery that would be difficult for a competitor to replicate.

•

Established and committed foundry partner network. We have built a high-volume foundry network comprised of strategic partners who share our growth vision, and our engineering team continues to work to push new boundaries in photonic component manufacturing processes.

Our high-performance optical sensing products and technology with broad biomarker detection capabilities, combined with the power of our algorithms and AI platform, enable us to target unmet needs and challenges in the health and wellness markets. We have ongoing formal and informal collaborative discussions with industry and technology leaders in consumer sensor, healthcare, and data communications companies, with original equipment manufacturer (“OEMs”), and with module and component vendors concerning the design of architectures and products to address existing and next-generation applications. Based on these interactions, we believe that we are one of a limited number of suppliers to these companies for the type of products we plan to sell, and in some cases, we may be the sole supplier for certain applications.

Our Strategy

Our strategy is to become the leading global provider of sensing products that incorporate integrated optical modules with supporting electronics, software, application algorithms, and cloud-based AI platforms for high-volume and high-margin applications in dynamic high-growth market sectors and for use-case specific opportunities with a focus on medtech and healthcare. Key elements of our strategy include:

•

Extend our silicon photonics leadership. We intend, through continuous platform engineering and advanced research and development, to continue driving innovation in the silicon photonics market and to improve the performance of our current solutions across a variety of key metrics, including size, power, and signal quality. Such innovation will be a key to opening new market opportunities.

•

Identify and promote new and emerging applications for our technologies. We are actively engaged with our science and technology partners to explore new potential markets and applications for our technology. We intend to continue to collaborate with our partners to understand the challenges in their end-product roadmaps and to demonstrate how our technologies can help them design and enable innovative solutions.

•

Develop our product portfolio. Beginning with our first target products in the consumer and medtech domains and for on-the-wrist applications, we intend to develop and broaden our product portfolio by continuing to invest in research and development so we can expand our platform capabilities as well as enhance our existing product roadmap. We are actively conducting research and development on other form factors and domains. We believe our differentiated technology will play an important role in delivering products for remote patient monitoring needs and for other niche markets such as diet and weight management, women’s health, and early detection and monitoring of chronic diseases such as diabetes.

•

Continue forming strategic partnerships in products and applications: Working with our partners, we have developed many potential product application opportunities with our unique technology that can be researched and unlocked in the future. Our partners operate in various domains such as hardware development, algorithm development, AI, and clinical research.

•

Continue to attract and acquire new customers. We intend to expand our customer base beyond our 17 existing customers in consumer electronics and medtech by focusing on direct dialogue with large strategic accounts, as well as by partnering with large distributors and resellers, when necessary. We believe this multi-track strategy will allow us to provide differentiated solutions to a broad array of customers.

•

Sustain margin through expansion of our products into higher-end markets. We intend to use our technological expertise to deliver higher value and high product margins. In addition, we intend to continue to reduce our costs through operational improvements and supply-chain management initiatives.

Our Technology Platform and Product Offerings

Our solutions leverage our developed knowledge of silicon photonics, application science, and our innovative platform architecture to address high-volume applications in the consumer sensors, medtech and healthcare. We believe our leadership position in developing silicon photonics-based sensing solutions is a result of the following core strengths:

•

We have developed a unique and proprietary silicon photonics platform technology that addresses a broad set of requirements in the healthcare and wellness industries.

•

Our custom multi-micron-waveguide photonics-optimized process with integrated III-V semiconductor actives brings multiple competitive advantages in terms of performance and manufacturability, offering lower waveguide losses, higher waveguide power handling, polarization independence, ubiquitous integration of III-V actives in their native known-good-die form, ultra-broad-band performance, and lower sensitivity to manufacturing variations while enabling compact circuitry with high integration densities.

Figure 5: Rockley spectrophotometer chip solution, as compared to conventional LED- and spectrometer-based solutions

LOGO

Additional key points concerning the photonics technology include the following:

•

The optical-loss-per-unit distance is much lower than for other technologies, enabling lower-power solutions and/or larger-scale PICs, which enables a high signal-to-noise ratio and hence high-fidelity signal detection and helps reduce overall power consumption;

•

The platform provides broadband performance and is suitable for the visible, short-wave, and mid-infrared bands. This is a key enabler for sensing applications that other platforms cannot serve. Broadband optical performance also enables sensing a large optical spectrum to cover a wide range of measurands;

•

The platform is well suited to power-efficient integration of III-V waveguide devices such as lasers and modulators that also have a multi-micron mode size. Low-loss coupling from III-V to Si waveguide drives down power consumption for long battery life;

•

A larger waveguide is much less sensitive to manufacturing variations that can affect its shape and hence its refractive index, thereby achieving much better center wavelength registration than small waveguides enabling accurate wavelength filters. The large waveguides also offer a much higher optical power handling capability than small waveguides;

•

Rockley’s waveguides exhibit low dispersion (low signal distortion) and low polarization dependent loss (simplifying receiver architectures in particular);

•

Strong optical confinement enables tight packing of waveguides and sharp waveguide bends, thereby yielding dense layout capability and compact PICs. Compact PIC layouts result in small chip sizes to fit within consumer device form factors and reduce product cost;

•

Accurate wavelength targeting enables using many finely-spaced wavelengths for accurate detection;

•

Known-good-die integration of active elements improved yields, which leads to cost-effective solutions.

The following are the key components of our end-to-end (full-stack) platform model:

•

Photonic integrated circuits in silicon with integrated III-V: The design and large-scale manufacturing of silicon photonic PICs and integration of active “III-V” elements onto these PICs are the foundational competencies of Rockley. These PICs are manufactured using our proprietary and highly differentiated process flow deployed at our foundry partners;

•

Application-specific integrated circuits (“ASICs”): The design of electronic ICs to complement our PICs and facilitate their integration into a specific end-product is the second key component of our platform offering. The ICs are designed in volume complementary metal-oxide-semiconductor (“CMOS”) or bipolar CMOS (“BiCMOS”) technology nodes using standard design flows and are manufactured at volume-scale foundries;

•

Photonic & electronic co-packaging: The next layer of the stack conjoins photonic and electronic ICs into opto-electronic engines through advanced co-packaging technologies, including 2.5D and 3D integration. Such dense integration is key and enables us to achieve the energy efficiency and physical size requirements for our core use cases. We partner with specialized packaging houses to provide the capacity required for serving consumer markets;

•

System architecture & hardware design: We have built deep expertise in architecting photonic systems for sensing solutions in healthcare and wellness, machine vision, and data communications. This enables us to go beyond making chips and allows us to deliver higher value-add photonic subsystems, modules, and chipsets that fit seamlessly into our end-product partners’ designs;

•

Firmware/software: Any system requires some degree of firmware and software to operate and inter-operate, and our photonic systems are no exception. We have in-house expertise to develop the necessary firmware and software to complement our hardware offerings and facilitate system integration, testing, and monitoring by our customers; and

•

Sensing algorithms, AI, and cloud analytics: At the highest level of the stack, we develop algorithms, AI models, and cloud-based infrastructure to gain deeper insights into health and wellness trends from the volume of sensor data collected by our wearable modules.

Figure 6: Rockley cloud analytics and AI

LOGO

We believe the key benefits that our solutions can provide to our customers are as follows:

•

Broad set of biomarkers with data analytics. Leveraging our unique integrated solution, we enable the detection and monitoring of multiple biomarkers. Analyzing the underlying spectral data with our growing base of machine learning and AI models has the potential to provide further insights into a person’s health;

•

Low power and small footprint. In each of the markets that we expect to serve, the power budget of the overall system is a key consideration. Power consumption greatly impacts system operation cost, footprint, and cooling requirements and is increasingly becoming a point of focus for our current customers and for other market participants that we are targeting as future customers. We believe that our silicon photonics solutions enable our customers to implement system architectures that reduce overall system power consumption. Moreover, in many of our applications, we are able to design and deliver semiconductors that have a smaller footprint and therefore reduce the overall system size; and

•

Faster time to market. To meet our customers’ time-to-market requirements, we work closely with them early in their design cycles and are actively involved in their development processes. Our hardware, algorithm, data analytics, and AI roadmaps provide flexibility in meeting our customers’ schedules.

Rockley’s Silicon Photonics Toolbox Elements

Rockley’s proprietary silicon photonics platform covers a unique end-to-end solution, including generation of the light, manipulation of the light (modulation, multiplexing), radiation out of the module, and collection and processing of the returned light. The following provides an overview of the key components of our platform:

•

Lasers: Our lasers offer precise wavelength control and robust power efficiency. The waveguide platform allows efficient wafer-scale integration of laser-devices through a flip-chip process;

•

Modulators and detectors: We have developed optical modulators and detectors that are ultra-compact, power-efficient and high-speed, capable of handling high data rates and a broad range of wavelengths;

•

Combiners and splitters: Our platform is capable of wavelength division multiplexing (“WDM”) and demultiplexing, enabling in excess of 100 wavelengths on a single optical path;

•

Fiber optic coupling: Our PIC contains on-chip embedded interfaces to the optical fibers. These interfaces allow the fiber to be passively attached directly to the PIC without external light coupling elements;

•

Free-space optics: Our platform allows for efficient light coupling from free space into and out of the photonics circuits, with either edge or perpendicular coupling. This feature enables a broad range of sensing applications;

•

Photonic integrated circuits: Our development platform enables integration of light sources, active devices, passive devices, and optical coupling elements into a single compact silicon chip;

•

Wafer-scale processing: Our silicon photonics platform enables high throughput wafer-scale processing of monolithic and multi-die structures for chip-on-wafer integration;

•

Interface electronics: We have in-house design expertise for custom analog circuitry to translate high-speed data streams into signals that actuate the PICs (drivers) and receive signals from them (amplifiers). This is complemented by our digital design capability for device control, signal processing, and interfaces to our customers systems; and

•

Packaged assembly: The assembly of electrical ASICs, PICs, and fiber optics (if needed) into a single, highly integrated product requires a test and manufacturing flow that enables high-volume scale.

Further application-based expertise is focused on the following:

•

Tissue optics design: Our sensing module products will include probe and hardware design to optimize sensing through the skin;

•

Biomarker application: Our sensing algorithms are being developed through various levels of validation to provide state-of-the-art sensing capabilities, from proof of concept in the lab to clinical validation in human studies; and

•

Applied data science: Our AI and cloud analytics will aggregate, analyze, and assess spectral data from our sensing products to extract additional insights and algorithm improvements.

Current Product Offerings

We have developed two separate product offerings to address our target markets: (i) VitalSpex (consume domain); and (ii) Bioptx (healthcare and medtech).

In respect of the VitalSpex biomarker sensing platform:

•

We will target applications in the consumer health and wellness industry and expect strong customer engagement in the consumer electronics and wearables market. The VitalSpex platform represents a breakthrough that will empower consumer electronic devices, primarily personal wearables, smartphones and homecare devices, with the capacity for new powerful healthcare and wellness monitoring;

•

The VitalSpex line will include a range of hardware and software solutions that enable non-invasive, continuous, and real-time monitoring of multiple biomarkers, from modules and chipsets that can be integrated into a wearable form factor to cloud analytics and artificial intelligence (AI);

•

The VitalSpex line will include a Baseline module, which will target the measurement of core body temperature, body, hydration, blood pressure, and more, and a Pro module, which will add the measurement of alcohol, lactate, and glucose trends. Our first health monitoring product offering is expected to launch in the second half of 2022; and

•

The VitalSpex Baseline and Pro modules will each combine existing LED-based optical sensing with Rockley’s proprietary infrared optical sensing to expand the range of biomarkers that wearable devices can measure. Our VitalSpex modules will include the hardware and software capabilities to collect information available and relevant to the target biomarkers.

•

We also plan to offer additional cloud-based subscription services that enhance the capabilities of the VitalSpex platform.

In respect of the Bioptx healthcare sensing platform:

•

The Bioptx platform will target medical institutions, such as hospitals, research clinics, pharmaceutical companies, medical device manufacturers, and other healthcare providers, offering them the ability to monitor the general health and wellness of individuals. The measurement capabilities of the Bioptx platform the potential to transform healthcare by providing real-time insights into a variety of health conditions and by enabling early detection of multiple disease states;

•

The Bioptx platform will include a range of hardware and software solutions that enable non-invasive, continuous, and real-time monitoring of multiple biomarkers, from a stand-alone wearable wristband to cloud analytics and artificial intelligence (AI);

•

The Bioptx platform will include Baseline products (for core body temperature, body, hydration, blood pressure, and more) and Pro products (which will add the measurement of alcohol, lactate, and glucose trends). Our first health monitoring product offering is expected to ship in the second half of 2022;

•

We also plan to offer additional cloud-based subscription services that enhance the capabilities of the Bioptx platform;

•

The intended markets for Bioptx products, including our wristband, are markets in the medical professional healthcare domain (i.e., not consumer) that require an optimized and dedicated solution for health monitoring. tracking, and detection; and

•

We expect that our customers will initially use the Bioptx platform to monitor the general wellness of individuals under care or in studies. After products in the Bioptx line receive approval from the FDA or other regulatory bodies, we anticipate that customers will expand product use into preventive and diagnostic care, such as remote patient monitoring and diagnosis.

Future Product Capabilities

We plan to incorporate our biomarker sensing technology into a range of existing devices, such as patches, wearable bands, and other monitoring devices, to provide additional biomarker measurement capabilities not currently available. We continuously research, evaluate, and prioritize the addition of new biomarkers into our product offerings, with the objective of providing more valuable information and improving health insights. Our broad range of addressable biomarkers are at various stage of validation and demonstration, from proven science to miniaturization. The chart below illustrates a few examples of biomarkers for which we have validated their addressability using its IR wavelengths.

Figure 7: Lab validation of Rockley’s sensing technology

LOGO

These biomarkers along a few others we are investigating are key in early detection, prevention, and monitoring of major chronic illnesses, as illustrated in the table below:

Figure 8: Disease detection and management potential of Rockley’s biomarker sensing platform

LOGO

These products are still under development, and there can be no assurance that these product development efforts will succeed or that, even if developed, that these products will achieve widespread market acceptance.

Customers

Our customers’ design cycle from initial engagement to volume shipment typically ranges from three to five years, with product life cycles of two years or more. For many of our products, which are technically complex, we must engage early with our customers’ technical staff. To ensure an adequate level of early engagement, our sales, marketing, and development engineers must work closely with our customers and channel partners to understand, identify, and propose solutions to meet their systems’ challenges. We work closely with our customers to anticipate end customer market needs. In some cases, we work with ecosystem partners to better understand market trends and new requirements that are being placed on our end customers.

We believe that our existing commercial relationships with leading consumer and medtech customers validate our unique technology and the business opportunity at hand. Our near-term commercial focus is on a robust pipeline in consumer devices, medical devices, and life sciences companies.

We work closely with our end customers throughout their design cycles and will develop long-term relationships as our differentiated technology becomes embedded into their products. For example, we currently hold a development and supply agreement with one customer since 2017 and have successfully designed and delivered critical sample chips to them. As a result, we believe we are well-positioned to be designed into their product roadmaps and develop next-generation solutions for their future products. Because many of our target customers or their OEMs are located in North America and Asia Pacific, we anticipate that a majority of our future revenue will come from sales in these regions. Although a large percentage of our sales are made to customers in North America, we believe that a significant number of the systems and devices designed by these customers will incorporate our semiconductor products which are then sold to end-users globally. We expect that once our modules are commercially available, we will enter into standard supply agreements with each of these parties.

Manufacturing

Our Proprietary Production and Manufacturing Ecosystem

We have built, and plan to continue to develop, a global manufacturing ecosystem designed with the ability to scale in a rapid and efficient manner. Several key areas within this manufacturing ecosystem run on our proprietary process and manufacturing technologies and are protected by our intellectual property portfolio. We possess end-to-end control over design, manufacturing and packaging processes, algorithms, and software. Our disciplined and systematic documentation and protection of critical know-how, trade secrets, and proprietary information further underpins our manufacturing ecosystem. To the best of our knowledge, there are no other turnkey options with the components and technologies needed to put together our sensing product. In addition to the intellectual property arrangements, we also have commercial exclusivity agreements with some of the key manufacturing ecosystem partners to prevent replication of this capability.

In addition to providing what we believe to be unmatched capabilities at the product level, our platform and the associated technology have been designed from bottom up to consider the relative ease and cost of manufacturing and scaling. Elements like waveguide dimensions for ease of wafer fabrication and high yields, robust and position tolerant coupling strategies for III-V integration, wafer scale back-end activities for III-V manufacturing, and all known good die integration at the module are integral to the product and the process technology. These elements are covered by the intellectual property which we have licensed to partners in our manufacturing ecosystem.

Manufacturing Model Overview

We plan to operate a fabless business model and use third-party foundries and Outsource Assembly & Test (OSAT) contractors to produce our products. In several key areas, our third-party partners operate a proprietary process wholly owned by us and protected by our intellectual property portfolio. This outsourced manufacturing approach allows us to focus our resources on the design, sale, and marketing of our products. In addition, we believe that outsourcing many of our manufacturing and assembly activities provides us with the flexibility needed to respond to new market opportunities and scale for customer demand, simplifies our operations, and significantly reduces our capital commitments.

We believe our fabless model will allow us to scale in a capex efficient manner. We have contracted with global tier-1 foundries, including Skywater (“SW”) for silicon PICs and wafer-scale III-V device integration and testing. This US based foundry is qualified for health, consumer and defense applications and has the capacity to meet our production needs. Our high-volume III-V semiconductor foundry is consumer and telecom qualified, supports very high volumes, and runs fully automated processes at one of the largest wafer scale in III-V manufacturing globally. Finally, our global IC foundry supplier handles the manufacturing of the electronic integrated circuits for our sensing modules. The foundry is used by most major consumer OEMs and is qualified for the ultra-high volume process node that we have chosen.

•

Raw Materials and Wafer Supply: The starting raw materials (SOI wafers) for our silicon photonics have been customized by world leading silicon providers for the Rockley proprietary specification. For the active III-V components, we have arrangements in place with the world’s leading epitaxial wafer supplier. We also have volume ready suppliers for commercial off-the shelf-components (“COTS”) that go into the visible sensing and the overall module.

•

Wafer Fabrication: Our SOI wafers are converted into fully processed silicon photonics PIC wafers at Skywater. The process used by SW is wholly owned by Rockley and licensed for use by SW only in Rockley products. The process design kit (“PDK”) for this process is developed and maintained by us and constitutes our intellectual property.

For the III-V active components, epitaxial materials are processed into finished wafers at a world leading dedicated III-V foundry making detectors, lasers and LEDs using state-of-the-art wafer-scale levels of automation. We have adapted the base process technology from this foundry to incorporate the previously discussed elements that allow for ease of integration into our platform and ease of manufacturing. These elements are exclusively for use in Rockley products.

Finally, for ASIC manufacturing, we use a standard process node and PDK provided to us by Taiwan Semiconductor Manufacturing Company, Limited. While the manufacturing process is widely used in high volume (good for product economics), the design know-how belongs to Rockley. The custom ASIC matches our silicon photonics platform optimally for low noise, low power and high level of integration.

•

Chipset and module integration: The chipset integration of the III-V active components into the silicon PICs is done at wafer scale and using passive alignment techniques that are uniquely enabled in our platform. Furthermore, we have ensured that the III-V components are in arrays of devices (reduces amount of alignment and integration activities) and on pretested known good die (“KGD”) which ensures very high compounded yields. The process intellectual property (“IP”) is developed and owned by Rockley and the integration is currently done in the UK at pilot production volumes, with plans to outsource higher volume in the future.

We have development and supply agreements in place with our key suppliers. These agreements cover the development program, economic framework, IP licenses, exclusivity terms and other matters. Although we have commenced long-term supply agreement discussions in parallel with the detailed manufacturing ramp discussions, we do not currently have any long-term supply agreements in place and transact business with our third-party suppliers on a purchase-order basis with no minimum supply obligations on their part. We have designed our manufacturing partner network to be resilient by having multiple sources of supply for several key processes/components and we have plans for the appropriate inventory and stocking strategies to mitigate risks to our ramp plans.

Commitment to Quality

We are committed to excellence by creating class-leading silicon photonics-based products and services. We intend to meet or exceed our global customer expectations by executing the following:

•

Creating long-lasting, trusting, and mutually beneficial relationships with customers and partners;

•

Establishing a full understanding of our customers’ requirements and ensuring our products and services meet their expectations;

•

Building a team of highly trained, empowered, and accountable employees;

•

Innovating in the creation of technology that drives our products and services;

•

Improving the effectiveness and efficiency of our quality management system through review of results, learning, and enhancement on a continual basis

We achieved ISO 9001:2015 certification in January 2022. We subject our third-party manufacturing contractors to rigorous qualification requirements to meet the high quality and reliability standards required of our products. We carefully qualify each of our partners and their processes. Our engineers work closely with our foundries (we even have teams embedded at partners sites in some critical areas) and other contractors to perfect the in-house processes, increase yield, lower manufacturing costs, and improve product quality. See “Risk Factors – Risks Related to Rockley’s Business and Industry” for a discussion of risks related to the semiconductor industry and Rockley’s manufacturing processes and foundry relationships.

Research and Development

We believe that our future success depends on our ability to develop new products for both existing and new markets, development enhancements to our products once developed or if and when commercially launched, to stay ahead of our competition by being leaders in extending the boundaries of our technologies. As a result, a significant amount of our operating expenses has been allocated towards next-generation platform development. Our research and development efforts are focused primarily on extending the functionality and addressable markets of our integrated photonics platform, as well as continually increasing its performance, efficiency, and volume manufacturing competitiveness. We have assembled a core team of experienced engineers and systems designers with an extremely broad range of skill sets across different disciplines who conduct research and development activities in the United States and various European locations, and we are supported by partnerships with leading research institutions and consumer electronics and medical devices companies. As of December 31, 2022, we had 230 employees globally with over 80% of our workforce focused on research, product development, and engineering.

Competition

The global optical components and full-stack solution market in general, and the consumer sensor, healthcare, and data communications markets in particular are highly competitive. We expect competition to increase and intensify as additional companies enter our target markets. Our competitors range from large, international companies offering a wide range of services and

optical components, such as LEDs, lasers, detectors, or PICs, to smaller companies specializing in narrow vertical markets. We expect competition in our target markets to increase in the future as existing competitors improve or expand their product offerings and as new competitors enter these markets. However, we believe that we are currently the only provider with the capability to integrate the technologies, features, and performance required by customers in our target markets. We believe that our unique silicon-photonic-based platform and the entire product ecosystem that we have developed around it will make our end-to-end offerings in the health and wellness domain difficult to replicate and provide us with a significant competitive moat. We believe this will be particularly true as we incorporate our AI and cloud-based offerings, currently under development.

Intellectual Property

We rely on a combination of intellectual property rights, including patents, trade secrets, copyrights and trademarks, and contractual protections, to protect our core technology and intellectual property. As of December 31, 2022, we had 262 issued patents and 310 other patent applications pending worldwide. The 114 issued and allowed patents in the United States expire in the years beginning in 2022 through 2040. Many of our issued patents and pending patent applications relate to sensors and sensor chips, and we have extensive geographic coverage over numerous relevant technology domains.

In addition to our own intellectual property, we also use third-party licensors for certain technologies embedded in our silicon photonics solutions. These are typically non-exclusive contracts provided under paid-up licenses. These licenses are generally perpetual or automatically renewed for as long as we continue to pay any maintenance fees that may be due. To date, maintenance fees have not constituted a significant portion of our annual capital expenditures. We have entered into a number of licensing arrangements pursuant to which we license third-party technologies. We do not believe our business is dependent to any significant degree on any individual third-party license.

We generally control access to and use of our confidential information and trade secrets through the use of internal and external controls, including contractual protections with employees, contractors, and customers. We rely in part on the laws of the United States and international laws to protect our work. All employees and consultants are required to execute confidentiality agreements in connection with their employment and consulting relationships with us. We also require them to agree to disclose and assign to us all inventions conceived or made in connection with the employment or consulting relationship. However, we cannot guarantee that we have entered into such agreements with every such party, and we may not have adequate remedies in case of a breach of any such agreements. Our trade secrets could be disclosed to our competitors or others may independently develop substantially equivalent technologies or otherwise gain access to our trade secrets. Trade secrets can be difficult to protect and some courts inside and outside of the United States are less willing or unwilling to protect trade secrets.

Government Regulation

Healthcare-Related Regulation

Our solutions may be incorporated into multi-application, health-related sensing, and monitoring applications, including healthcare consumer wearables. Accordingly, the end products into which our solutions are incorporated may be subject to FDA and similar or related regulations, and demand for these end products or future regulated products could be adversely affected if such end products do not comply with applicable requirements. Although our target market is consumer wellness rather than medical, we intend to monitor and comply with regulations to the extent they become applicable to us, including any requirements for FDA clearance. Certain healthcare-related products may be regulated by the FDA and corresponding state regulatory agencies in the United States and separate governmental authorities outside of the United States. In the United States, the medical device industry is regulated by governmental authorities, principally the FDA and corresponding state regulatory agencies. Before a new regulated product or a significant modification to an existing medical device may be marketed or sold in the United States, it must comply with FDA Quality Management System regulations, and must obtain regulatory clearance or approval from the FDA, unless an exemption from pre-market review applies. In addition, certain future software functionality, whether standalone or embedded in existing or future devices, may be regulated as a medical device and require pre-market review and clearance or approval by the FDA. The process of obtaining regulatory clearances or approvals to market a medical device can be costly and time consuming, and our end customers may not be able to obtain these clearances or approvals on a timely basis, or at all, for future products. Any delay in, or failure to receive or maintain, clearance or approval for any medical device products under development could prevent us from generating revenue from our solutions incorporated into these products.

Medical devices are also subject to numerous ongoing compliance requirements under the regulations of the FDA and corresponding state regulatory agencies, which can be costly and time consuming. For example, under FDA regulations medical device manufacturers are required to, among other things: (i) establish a quality management system to help ensure that their products consistently meet applicable requirements and specifications; (ii) establish and maintain procedures for receiving, reviewing, and evaluating complaints; (iii) establish and maintain a corrective and preventive action procedure; (iv) report certain device-related adverse events and product problems to the FDA; and (v) report to the FDA the removal or correction of a distributed product. If our solutions are incorporated into any medical device products of our end customers and these customers experience any product problems requiring reporting to the FDA or otherwise fail to comply with applicable FDA regulations or the regulations of corresponding state regulatory agencies, it could harm our ability to sell our solutions. In addition, if our end customers in the healthcare market are subject to enforcement actions such as fines, civil penalties, injunctions, recalls of products, delays in the introduction of products into the market, and refusal of the FDA or other regulators to grant future clearances or approvals, it could harm our reputation, business, operating results, and financial condition. In addition, in the United States, the FDA has taken the position that device manufacturers are prohibited from promoting their products other than for the uses and indications set forth in the approved product labeling, and any failure to comply could subject our end customers to significant civil or criminal exposure, administrative obligations and costs, and/or other potential penalties from, and/or agreements with, the federal government.

Government regulations outside the United States have, and may continue to, become increasingly stringent and common. In the European Union, for example, the European Union Medical Device Regulation was published in 2017 and, when it entered into full force in 2020, included significant additional pre-market and post-market requirements. Penalties for regulatory non-compliance could be severe, including fines and revocation or suspension of a company’s business license, mandatory price reductions, and criminal sanctions. Future laws and regulations may have a material adverse effect on our end customers in the healthcare market, which in turn may negatively impact our ability to sell our solutions and otherwise harm our business and financial results.

Export Regulation

Our business activities are also subject to various restrictions under U.S. export and similar laws and regulations, as well as various economic and trade sanctions administered by the U.S. Treasury Department’s Office of Foreign Assets Control. Further, various countries regulate the import of certain technology and have enacted or could enact laws that could limit our ability to provide customers with our products in those countries.

We are also subject to various domestic and international anti-corruption laws, such as the U.S. Foreign Corrupt Practices Act and the U.K. Bribery Act, as well as other similar anti-bribery and anti-kickback laws and regulations. These laws and regulations generally prohibit companies, their employees, and their intermediaries from authorizing, offering, providing, and/or accepting improper payments or other benefits for improper purposes. Although we take precautions to prevent violations of these laws, our exposure for violating these laws increases as our international presence expands and as we increase sales and operations in foreign jurisdictions.

New legislation or regulation, the application of laws from jurisdictions whose laws do not currently apply to our business, or the application of existing laws and regulations to technology in the wearables industry generally could result in significant additional compliance costs and responsibilities for our business.

Privacy

We are or may become subject to a variety of laws and regulations in the United States and abroad regarding privacy, data protection, and data security. These laws and regulations are continuously evolving and developing. The scope and interpretation of the laws that are or may be applicable to us are often uncertain and may be conflicting, particularly with respect to foreign laws.

In particular, there are numerous U.S. federal, state, and local laws and regulations and foreign laws and regulations regarding privacy and the collection, sharing, use, processing, disclosure, and protection of personal data. Such laws and regulations often have changes in scope, may be subject to differing interpretations, and may be inconsistent among different jurisdictions. For example, the General Data Protection Regulation (the “GDPR”), which became effective in May 2018, includes operational requirements for companies that receive or process personal data of residents of the European Union that are broader and more stringent than those previously in place in the European Union. The GDPR includes significant penalties for non-compliance, including fines of up to €20 million or 4% of total worldwide revenue. Additionally, in June 2018, California enacted the California Consumer Privacy Act (the “CCPA”), which became effective in January 2020. The CCPA requires covered companies to provide California consumers with new disclosures and expands the rights afforded consumers regarding their data. Fines for noncompliance may be up to $7,500 per violation. We cannot currently estimate the potential impact of the CCPA on our business or operations.

Additionally, we rely on various legal mechanisms for transferring certain personal data outside of the European Economic Area, or EEA, including the EU-U.S. Privacy Shield Framework, or Privacy Shield, and EU Standard Contractual Clauses, or SCCs. If we fail or are perceived to fail to meet the Privacy Shield principles or our obligations under the SCCs, or if any of these legal mechanisms for transferring data from the EEA are invalidated by European courts or otherwise become defunct, European Union data protection authorities or the U.S. Federal Trade Commission, or FTC, could bring enforcement actions seeking to prohibit or suspend our data transfers or alleging unfair or deceptive practices. In such cases, we could be required to make potentially expensive changes to our information technology infrastructure and business operations, and we could face legal liability, fines, negative publicity, and resulting loss of business.

Certain health-related laws and regulations such as the Health Insurance Portability and Accountability Act of 1996, or HIPAA, and the Health Information Technology for Economic and Clinical Health Act, or HITECH, may also have an impact on our business. If we are unable to comply with the applicable privacy and security requirements under HIPAA, HITECH, or PCI DSS, or we fail to comply with BAAs that we enter into with covered entities, we could be subject to claims, legal liabilities, penalties, fines, and negative publicity, which could harm our operating results.

Governments are continuing to focus on privacy and data security, and it is possible that new privacy or data security laws will be passed, or existing laws will be amended in a way that is material to our business. Any significant change to applicable laws, regulations, or industry practices regarding our users’ data could require us to modify our services and features, possibly in a material manner, and may limit our ability to develop new products, services, and features. Although we have made efforts to design our policies, procedures, and systems to comply with the current requirements of applicable state, federal, and foreign laws, changes to applicable laws and regulations in this area could subject us to additional regulation and oversight, any of which could significantly increase our operating costs.

We strive to comply with all applicable laws, policies, legal obligations, and industry codes of conduct relating to privacy, data security, and data protection. The costs of compliance with, and other burdens imposed by, the GDPR, CCPA, HIPAA, and similar laws may limit the use and adoption of our products and services, and/or require us to incur substantial compliance costs, which could have

an adverse impact on our business. In addition, given that the scope, interpretation, and application of these laws and regulations are often uncertain and may be conflicting, it is possible that these obligations may be interpreted and applied in a manner that is inconsistent from one jurisdiction to another and may conflict with other rules or our practices. Any failure or perceived failure by us, our end customers, or third-party service-providers to comply with our privacy or security policies or privacy-related legal obligations, the failure or perceived failure by our end customers to comply with their privacy policies or privacy-related legal obligations, or any compromise of security that results in the unauthorized release or transfer of personal data, may result in governmental enforcement actions, litigation, damages, penalties, and negative publicity, and could also have an adverse effect on our brand and operating results.

Cybersecurity

We have designed and implemented and continue to maintain a security program consisting of policies, procedures, and technology intended to maintain the privacy, security and integrity of our information, systems, and networks. Among other things, the program includes controls designed to limit and monitor access to authorized systems, networks, and data, prevent inappropriate access or modification, and monitor for threats or vulnerability.

Item 1A. Risk Factors

Unless specifically noted or the context clearly requires otherwise, all information set forth in this annual report on Form 10-K relates to the Company as it existed as of December 31, 2022 and prior to the Company’s bankruptcy proceedings and does not, and is not intended and should not be read to, reflect the business, financial condition, and results of operations of any other entity, including any entity which may result from the bankruptcy proceedings.

As used in the risks described in this subsection, references to “the Company,” “Rockley,” “we,” “us,” and “our,” are intended to refer to the business and operations of Rockley, unless the context clearly indicates otherwise.

Rockley may be unable to successfully implement the Plan of Reorganization and could therefore be required to cease operations.

On March 10, 2023, Rockley filed a voluntary petition for relief under chapter 11 of title 11 of the United States Code in the Bankruptcy Court to implement the “Plan of Reorganization” in order to facilitate its restructuring. On March 10, 2023, the Bankruptcy Court entered its Order approving the Plan of Reorganization. Rockley’s ordinary shares and public warrants have been delisted from the New York Stock Exchange and Rockley intends to file to deregister as a public company shortly after the filing of this Form 10-K. Rockley may be unable to successfully implement the Plan of Reorganization and restructuring and could therefore fail to emerge from bankruptcy, in which case it would cease operations as an independent company or otherwise. The risk factors described below relate to Rockley’s business assuming it is able to continue its business operations.

Risks Related to Rockley’s Business and Industry; Customer-Related Risks

Rockley has incurred net losses since inception and expects to continue to incur losses for the foreseeable future. If Rockley does not fully develop or commercialize its products and services, including its silicon photonics chipsets, or if such products and services experience significant delays, Rockley’s business, financial condition, and results of operation will be materially and adversely affected and Rockley may never achieve or sustain profitability.

Rockley has to date generated revenue primarily from non-recurring engineering (“NRE”) and development services for customer-specific designs of silicon photonics chipsets for incorporation into its customers’ end products. Rockley has incurred net losses since inception and believes that it will continue to incur operating and net losses for the foreseeable future, including for a period of time after commercialization, if any, of its silicon photonics chipsets. Even if Rockley is able to successfully develop and sell its products, there can be no guarantee that it will do so within its anticipated timeframe or that its products will be commercially successful. Rockley’s potential future profitability is dependent upon the successful development, commercial introduction, and acceptance of its products and services, including its silicon photonics chipsets for the consumer wearables market and its module applications with biomarker detection capabilities for advanced health metrics. Because Rockley will incur costs to develop and commercialize its products and services, including its chipsets and module applications, before it receives any significant revenue from any sales of such products or services, Rockley’s losses in future periods may continue. Rockley may never achieve or sustain profitability.

Rockley may become subject to restrictive debt covenants that may limit its ability to finance its future operations and capital needs and to pursue business opportunities and activities.

Rockley’s financing agreements prior to the bankruptcy proceedings contained restrictive covenants, including a requirement to maintain at least $35 million cash on hand, that limit its ability to take certain actions. While these financing arrangements were extinguished in connection with the bankruptcy proceedings, Rockley may in the future need to enter into financing arrangements with similar restrictive covenants. These restrictions may limit Rockley’s ability to operate its businesses and may prohibit or limit its activity to enhance its operations or take advantage of potential business opportunities as they arise. All of these limitations are subject to significant exceptions and qualifications. These covenants could limit Rockley’s ability to finance its future operations and capital needs and its ability to pursue business opportunities and activities that may be in its interest. If Rockley breaches any such covenants it may be in default under its indebtedness, which may then become immediately due and payable. Rockley may not have, or be able to obtain, sufficient funds to make these accelerated payments. Rockley’s ability to comply with the provisions of its financing arrangements may be affected by changes in economic or business conditions or other events beyond its control.

If the end products into which Rockley’s products are incorporated are not fully developed and commercialized or do not achieve widespread market acceptance, or if such products experience delays, cancellations, or reductions, Rockley’s business, financial condition, and results of operations will be materially and adversely affected.

Rockley’s success in developing and commercializing its products depends in large part on its customers’ success in developing, commercializing, and achieving widespread market acceptance of their end products that incorporate Rockley’s products. Rockley’s customers may be unable to fully develop and commercialize, or achieve widespread market acceptance of, their end products that incorporate Rockley’s products. Further, these customers may not continue to incorporate Rockley’s products into their end products either in the short or long term. If such customers’ end products are not fully developed and commercialized, fail to achieve or maintain widespread market acceptance, experience delays, or if Rockley’s customers otherwise choose not incorporate Rockley’s products into their end products, Rockley’s business, financial condition, and results of operations will be materially and adversely affected.

If Rockley’s products are not selected for inclusion in its customers’ end products, including products for the consumer health and wellness market, or adopted in other industry verticals or use cases or are not adopted by leading consumer and medical device companies, life sciences companies, or their respective suppliers, Rockley’s business will be materially and adversely affected.

Rockley is currently developing products for use in its customers’ end products, which are in varying stages of development. Many of these products, including products for consumer device, medical device, and life sciences companies, require extensive testing or qualification processes, which involve testing of Rockley’s products in the customers’ end products and systems, as well as testing for reliability. These qualification processes may continue for several months or longer. However, qualification of any of Rockley’s products by a customer does not assure any sales of such product by Rockley to that customer. Even after successful qualification and sales by Rockley of a product to a customer, a subsequent revision in Rockley’s third-party contractors’ manufacturing process or Rockley’s selection of a new supplier may require a new qualification process with Rockley’s customers, which may result in delays in the sale of such product and could also result in Rockley holding excess or obsolete inventory. After Rockley’s products are qualified, it can take several months before the customer commences production of end products that incorporate Rockley’s products. Rockley spends significant time and resources to have its products selected for incorporation into these end products, which is known as a “design win.” If Rockley fails to win a significant number of design wins in its target markets, its business, results of operations, and financial condition will be materially and adversely affected.

Rockley’s limited operating history makes it difficult to evaluate its future prospects and the risks and challenges which may impact its business.

Rockley was founded in 2013, completed development of its advanced sensing platform in 2019, launched its healthcare module offering in 2020, and has not yet fully developed and commercialized any of its products. This relatively limited operating history makes it difficult to evaluate Rockley’s future prospects and the risks and challenges it may encounter. The risks and challenges which may impact Rockley’s future prospects and business include, but are not limited to, its ability to:

•

successfully commercialize its products and services, including its silicon photonics chipsets, module applications, and analytics subscription service;

•

develop innovative applications for its silicon photonics and sensing technology;

•

expand its sales and marketing activities and distribution channels;

•

improve its operational, financial, and management information systems;

•

attract, hire, integrate, and retain qualified talent to support the growth of its business;

•

protect its intellectual property portfolio;

•

comply with existing and new or modified laws and regulations applicable to its business;

•

manage capital expenditures for its current and future products, as well as its supply chain and supplier relationships;

•

anticipate and respond to macroeconomic changes and changes in the markets in which it operates;

•

effectively manage its growth and business operations, including the impacts of the COVID-19 pandemic on its business; and

•

hire, integrate, and retain qualified talent to support the growth of its business.

If Rockley fails to successfully manage the risks and difficulties that it faces, its business, financial condition, and results of operations could be materially and adversely affected. Further, because Rockley has a limited operating history and has not yet commercialized its products, it is difficult to accurately assess its future prospects or financial performance. Rockley has encountered in the past, and will encounter in the future, risks and uncertainties frequently experienced by growing companies with limited operating histories in rapidly changing industries. If Rockley’s assumptions regarding these risks and uncertainties, which it uses to plan and operate its business, are incorrect or change, or if it does not address these risks successfully, its results of operations could differ materially from its expectations and its business, financial condition, and results of operations could be materially and adversely affected.

The strategic initiatives Rockley may undertake in the future may be more costly than currently anticipated and Rockley may not generate sufficient revenue to offset the costs of these initiatives, which in turn would negatively impact Rockley’s ability to achieve and maintain profitability.

Rockley may in the future invest in initiatives designed to grow its business, including:

•

partnering with customers and potential customers to develop and commercialize Rockley’s products;

•

investing in research and development;

•

investing in its workforce, including its engineering talent;

•

expanding its sales, marketing, and distribution efforts;

•

investing in new applications and markets for its products; and

•

partnering with third-parties to develop manufacturing processes.

These initiatives may be more costly than anticipated and Rockley may not generate sufficient revenue to offset the costs of these initiatives. Certain of Rockley’s market opportunities, such as healthcare monitoring devices incorporating sensing capabilities for disease detection and management, are at an early stage of development, and it may be years before these end markets generate demand for Rockley’s products at scale, if at all. Rockley’s revenue may be adversely affected for a number of reasons, including the rate and degree of development or market acceptance of new technology that competes with its products, failure of Rockley’s customers to develop and commercialize their end products that incorporate Rockley’s products, Rockley’s inability to effectively manage production of its products to scale, Rockley’s inability to enter new markets or help its customers adopt Rockley’s products for new applications, and Rockley’s failure to attract new customers or expand orders from existing customers. Further, it is difficult to predict the size and growth rate of Rockley’s target markets, customer demand for its products, commercialization timelines, developments in silicon photonics technology, the entry of competitive products, or the success of existing competitive products and services. If Rockley’s revenue does not grow over the short or long term, its ability to achieve and maintain profitability will be adversely affected, and the value of its business may significantly decrease.

Rockley expects its results of operations to fluctuate on a quarterly and annual basis.

Rockley’s revenue and operating results have fluctuated in the past and may vary significantly in the future. Historical comparisons of its operating results may not be relevant, or indicative of future results. In particular, because Rockley’s revenue to date has been generated from NRE and development services for customer-specific designs of silicon photonics chipsets for testing in the customers’ end products, revenue in any given quarter or period can fluctuate based on the timing and success of its customers’ development projects. Accordingly, the results of any one quarter should not be relied upon as an indication of future performance. Rockley’s quarterly and annual financial results may fluctuate as a result of a variety of factors, many of which are outside of its control and may not fully reflect the underlying performance of Rockley’s business.

Rockley’s target customer and product markets may not grow or develop as Rockley currently expects, and if Rockley fails to penetrate new markets and scale successfully within those markets, Rockley’s revenue and financial condition would be harmed.

Rockley’s target markets include the consumer wearables, mobile device, and medical device markets. Any deterioration in Rockley’s target customer or product markets or reduction in capital spending to support these markets could lead to a reduction in demand for Rockley’s products, which would adversely affect its revenue and results of operations. Further, if Rockley’s target customer markets do not grow or develop in ways that Rockley currently expects, demand for Rockley’s products may not materialize as expected, which would also negatively impact its business, financial condition, and results of operations. Rockley may be unable to predict the timing or development of trends in its target markets with any accuracy. If Rockley fails to accurately predict market requirements or market demand for these solutions, Rockley’s business may suffer.

Rockley’s future revenue growth, if any, will depend in part on Rockley’s ability to penetrate Rockley’s current target markets, and to enter emerging markets, such as the market for consumer healthcare monitoring devices and predictive analytics. Meeting the technical requirements and securing design wins in any of these new markets will require a substantial investment of Rockley’s time and resources. Rockley may not secure design wins from these or other new markets, or achieve meaningful revenue from sales in these markets. If any of these markets do not develop as Rockley currently anticipates or if Rockley is unable to penetrate and scale them successfully, it may adversely affect Rockley’s ability to grow its business.

Rockley’s target markets are characterized by rapid technological change, which requires Rockley to continue to develop new products and technology innovations and could adversely affect market adoption of its products.

Rapid technological changes in the markets for sensing technology, including the consumer wearables, mobile device, and medical device markets, could adversely affect adoption of Rockley’s products, either generally or for particular applications. Rockley’s future success will depend upon its ability to develop and introduce a variety of new capabilities and innovations to its products, as well as introduce new products, to address the changing needs of its target markets. Delays in delivering new products that meet customers’ requirements could damage Rockley’s relationships with its customers and lead them to seek alternative sources of supply. Further, the introduction of new products by Rockley’s competitors, the delay or cancellation of any of Rockley’s customers’ end products into which Rockley’s products are designed, the market acceptance of products based on new or alternative technologies, or the emergence of new industry standards could render Rockley’s existing or future products uncompetitive, obsolete, and/or otherwise unmarketable.

In addition, Rockley’s success to date has been based on the delivery of prototypes and services to research and development programs in which customers are investing substantial capital to develop new products. Delays in introducing products and innovations, the failure to choose correctly among technical alternatives, or the failure to offer innovative products at competitive

prices may cause existing and potential customers to purchase Rockley’s competitors’ products or turn to alternative sensing technology. If Rockley is unable to successfully develop products that meet changing customer or market requirements on a timely basis or that remain competitive with technological alternatives, its products may fail to achieve commercial adoption, its revenue will decline, it may experience operating losses, and its business and prospects will be adversely affected.

Rockley may be unable to make the substantial investments that are required to remain competitive.

The silicon photonics industry requires substantial and continuous investment in research and development in order to bring to market new and enhanced solutions. Rockley expects its research and development expenditures to increase in the future as part of its strategy to increase demand for Rockley’s solutions in Rockley’s current target markets and to expand into additional markets. Rockley may not have sufficient resources to maintain the level of investment in research and development required to remain competitive. In addition, Rockley cannot assure you that the technologies that are the focus of its research and development expenditures will become commercially successful or generate any revenue.

If Rockley fails to compete effectively, it may lose or fail to gain market share, which could negatively impact Rockley’s operating results and Rockley’s business.

The global optical components market in general, and the consumer sensor, healthcare, and data communications markets in particular, are highly competitive. Rockley expects competition to increase and intensify as additional companies enter Rockley’s target markets. Increased competition could result in price pressure, reduced gross margins, and difficulty achieving market penetration, any of which could harm Rockley’s business, financial condition, and results of operations. Rockley’s competitors range from large, international companies offering a wide range of services and optical components, such as LEDs, lasers, detectors, or photonic integrated circuit (“PICs”), to smaller companies specializing in narrow market verticals. Rockley expects competition in its target markets to increase in the future as existing competitors improve or expand their product offerings and as new competitors enter these markets. Rockley’s ability to compete successfully depends, in part, on factors that are outside of its control, including industry and general economic trends. Rockley’s competitors may also establish cooperative relationships among themselves or with third parties or may acquire companies that provide similar products to Rockley’s. As a result, new competitors or alliances may emerge that could capture significant market share. Any of these factors, alone or in combination with others, could harm Rockley’s business, financial condition, and results of operations and result in a loss of market share and an increase in pricing pressure.

Rockley’s international operations expose it to operational, financial, and regulatory risks, including possible unfavorable regulatory, political, tax, and labor conditions, which could harm Rockley’s business.

Rockley’s international operations are subject to a number of other risks, including:

•

foreign currency fluctuations, which could result in increased operating expenses and reduced revenue;

•

political and economic instability, international terrorism, and anti-American or British sentiment, particularly in emerging markets;

•

disadvantages of competing against companies from countries that are not subject to U.S. and U.K. laws and regulations, including the Foreign Corrupt Practices Act, Office of Foreign Assets Control regulations, and U.S. anti-money laundering regulations, as well as exposure of Rockley’s foreign operations to liability under these regulatory regimes;

•

preference for locally branded products, and laws and business practices favoring local competition;

•

potential consequences of, and uncertainty related to, the “Brexit” process in the United Kingdom, which could lead to additional expense and complexity in doing business there;

•

less effective protection of intellectual property;

•

stringent regulation of the end products incorporating Rockley’s products and stringent consumer protection and product compliance regulations, including but not limited to General Data Protection Regulation in the European Union, European competition law, the Restriction of Hazardous Substances Directive, the Waste Electrical and Electronic Equipment Directive, and the European Ecodesign Directive that are costly to comply with and may vary from country to country;

•

difficulties and costs of staffing and managing foreign operations;

•

foreign taxes, including withholding of payroll taxes; and

•

the U.S. government’s and U.K. government’s restrictions on certain technology transfer to certain countries of concern.

For example, Rockley has significant international operations that are denominated in foreign currencies, primarily the British Pound and Euro, subjecting us to foreign currency exchange risk that may adversely impact our financial results. The occurrence of any of these risks could negatively affect Rockley’s international business and consequently its business, operating results, and financial condition.

The average selling prices of Rockley’s products could decrease rapidly over the life of the product, which may negatively affect Rockley’s revenue and margins. In addition, the selling prices Rockley is able to ultimately charge in the future for the products it is currently developing or commercializing may be less than what Rockley currently anticipates, which may cause Rockley’s actual operating results to differ materially from its expectations.

The prices that Rockley is able to ultimately charge in the future for the products it is currently developing or commercializing may experience declines for a variety of reasons, many of which are outside of Rockley’s control. In order to sell products that have a falling average unit selling price and maintain margins at the same time, Rockley will need to continually reduce product and manufacturing costs. To manage manufacturing costs, Rockley must engineer the most cost-effective design for its products and collaborate with its manufacturing counterparties to reduce manufacturing costs. Rockley also needs to continually introduce new products with higher sales prices and gross margin in order to maintain its overall gross margin. If Rockley is unable to manage the cost of older products or successfully introduce new products with higher gross margin, its revenue and overall gross margin would likely decline. In addition, the selling prices Rockley is able to ultimately charge in the future for the products it is currently developing or commercializing may be less than what Rockley currently projects, which may cause Rockley’s actual operating results to differ materially from its estimates.

Rockley’s gross margins may fluctuate due to a variety of factors, which could negatively impact Rockley’s results of operations and Rockley’s financial condition.

Rockley’s gross margins may fluctuate due to a number of factors, including customer and product mix, market acceptance of Rockley’s new products, yield, wafer pricing, packaging and testing costs, competitive pricing dynamics, the impact of the COVID-19 pandemic, and geographic and market pricing strategies. To the extent Rockley may offer certain customers favorable prices, it would decrease Rockley’s average selling prices and likely impact gross margins. Further, Rockley may in the future offer pricing incentives to Rockley’s customers on earlier generations of products that inherently have a higher cost structure, which would negatively affect Rockley’s gross margins. In addition, in the event Rockley’s customers, including Rockley’s larger customers, exert more pressure with respect to pricing and other terms, it could put downward pressure on Rockley’s margins.

Because Rockley does not operate its own manufacturing, assembly, or testing facilities, it may not be able to reduce its costs as rapidly as companies that operate their own facilities, and Rockley’s costs may even increase, which could further reduce Rockley’s gross margins. Rockley relies primarily on obtaining yield improvements and volume-based cost reductions to drive cost reductions. To the extent that such cost reductions do not occur at a sufficient level and in a timely manner, Rockley’s business, financial condition, and results of operations could be adversely affected and may vary from Rockley’s estimates.

In addition, Rockley may in the future maintain an inventory of Rockley’s products at various stages of production and in finished goods inventory. Rockley will hold these inventories in anticipation of customer orders. If those customer orders do not materialize in a timely manner, Rockley may have excess or obsolete inventory which Rockley would have to reserve or write-down, and Rockley’s gross margins would be adversely affected.

Because some of the raw materials and key components in its products come from limited or single source suppliers, Rockley is susceptible to supply shortages, long lead times for components, and supply changes, including as a result of industry consolidation, any of which could disrupt its supply chain and could delay deliveries of its products to customers, which could adversely affect Rockley’s business, results of operations, and financial condition.

Some of the components used in the manufacturing of Rockley’s products are sourced from third-party suppliers. To date, Rockley has produced its products in relatively limited quantities for use in products. Rockley does not have extensive experience in managing its supply chain to manufacture and deliver its products at scale. Some of the key components used to manufacture Rockley’s products come from limited or single source suppliers. Rockley is therefore subject to the risk of shortages and long lead times in the supply of these components and the risk that its suppliers discontinue or modify components used in its products. Rockley has a global supply chain and the COVID-19 pandemic and other health epidemics and outbreaks may adversely affect its ability to source components in a timely or cost effective manner from its third-party suppliers due to, among other things, work stoppages or interruptions. For example, Rockley relies on third-party foundries to manufacture its silicon photonic integrated circuits and for wafer scale integration. Any disruptions to those foundries could materially and adversely affect Rockley’s ability to manufacture its products. In addition, the lead times associated with certain components are lengthy and preclude rapid changes in quantities and delivery schedules. Rockley has in the past experienced and may in the future experience component shortages and price fluctuations of certain key components and materials, and the predictability of the availability and pricing of these components may be limited. In the event of a component shortage, supply interruption or material pricing change from suppliers of these components, Rockley may not be able to develop alternate sources in a timely manner or at all in the case of sole or limited sources. These risks may be exacerbated if any of Rockley’s suppliers were to cease operations or be acquired by a third party. If this were to occur, Rockley may need to re-qualify the supplier and/or otherwise confirm that such an event would not cause concerns with Rockley’s end customers or otherwise negatively impact Rockley’s relationships with its end customers. Developing alternate sources of supply for these components may be time-consuming, difficult, and costly and Rockley may not be able to source these components on terms that are acceptable to it, or at all, which may undermine Rockley’s ability to meet its requirements or to fill customer orders in a timely manner. Any interruption or delay in the supply of any of these parts or components, or the inability to obtain these parts or

components from alternate sources at acceptable prices and within a reasonable amount of time, would adversely affect Rockley’s ability to meet its scheduled product deliveries to its customers. This could adversely affect Rockley’s relationships with its customers and channel partners and could cause delays in shipment of its products and adversely affect its operating results. In addition, increased component costs could result in lower gross margins. Even where Rockley is able to pass increased component costs along to its customers, there may be a lapse of time before it is able to do so such that Rockley must absorb the increased cost. If Rockley is unable to buy these components in quantities sufficient to meet its requirements on a timely basis, it will not be able to deliver products to its customers. This in turn could materially and adversely affect Rockley’s business, financial condition, and results of operations.

If the foundries with which Rockley contracts do not achieve satisfactory yields or quality, Rockley’s reputation and customer relationships could be harmed.

Rockley depends on satisfactory wafer foundry manufacturing capacity, wafer prices, and production yields, as well as timely wafer delivery, to meet customer demand and enable it to maintain gross margins. The fabrication of Rockley’s products is a complex and technically demanding process. Minor deviations in the manufacturing process can cause substantial decreases in yields and, in some cases, cause production to be suspended. Rockley’s foundry vendors may experience manufacturing defects and reduced manufacturing yields from time to time. Further, any new foundry vendors Rockley employs, whether due to industry consolidation, customer requirements, or otherwise, may present additional and unexpected manufacturing challenges that could require significant management time and focus. Changes in manufacturing processes or the inadvertent use of defective or contaminated materials by the foundries that Rockley employs could result in lower than anticipated production yields or unacceptable performance of Rockley’s products. Many of these problems are difficult to detect at an early stage of the manufacturing process and may be time-consuming and expensive to correct. Poor production yields from the foundries that Rockley employs, or defects, integration issues, or other performance problems in Rockley’s products could significantly harm Rockley’s customer relationships and financial results, and give rise to financial or other damages to Rockley’s customers. Any product liability claim brought against Rockley, even if unsuccessful, would likely be time-consuming and costly to defend.

Manufacturing yields for new products initially tend to be lower as Rockley completes product development and commence volume manufacturing, and typically increase as Rockley brings the product to full production. While Rockley’s business model includes this assumption of improving manufacturing yields its assumptions may be incorrect and, as a result, material variances between projected and actual manufacturing yields will have a direct effect on Rockley’s gross margin and profitability. The difficulty of accurately forecasting manufacturing yields and maintaining cost competitiveness through improving manufacturing yields will continue to be magnified by the increasing process complexity of manufacturing silicon photonics products.

Raw material price fluctuations can increase the cost of Rockley’s products, impact Rockley’s ability to meet customer commitments, and may adversely affect its results of operations.

The cost of raw materials is a key element in the cost of Rockley’s products. Rockley’s inability to offset material price inflation through increased prices to customers, suppliers, productivity actions, or through commodity hedges could adversely affect Rockley’s results of operations. Many major components, product equipment items, and raw materials are procured or subcontracted on a single or sole-source basis. Although Rockley maintains a qualification and performance surveillance process and Rockley believes that sources of supply for raw materials and components are generally adequate, it is difficult to predict what effects shortages or price increases may have in the future. Rockley’s inability to fill its supply needs would jeopardize its ability to fulfill its contractual obligations, which could, in turn, result in reduced revenue, contract penalties or terminations, and damage to Rockley’s customer relationships.

Furthermore, increases in the price of wafers, testing costs, and commodities, which may result in increased production costs, mainly assembly and packaging costs, may result in a decrease in Rockley’s gross margins. Moreover, Rockley’s suppliers may pass the increase in raw materials and commodity costs onto it which would further reduce the gross margin of Rockley’s products. In addition, as Rockley is a fabless company, global market trends such as a shortage of capacity to fulfill Rockley’s fabrication needs also may increase Rockley’s raw material costs and thus decrease its gross margin.

Rockley is subject to the cyclical nature of the semiconductor industry.

The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence, price erosion, evolving standards, short product life cycles, industry consolidation, and wide fluctuations in product supply and demand. The industry experienced significant downturns during past global recessions. These downturns have been characterized by diminished product demand, production overcapacity, high inventory levels, and accelerated erosion of average selling prices. While these downturns have not directly impacted Rockley’s business to date, any prolonged or significant downturn in the semiconductor industry could adversely affect Rockley’s business and reduce demand for Rockley’s products. Any future downturns in the semiconductor industry could also harm Rockley’s business, financial condition, and results of operations. Furthermore, any significant upturn in the semiconductor industry could result in increased competition for access to third-party foundry and assembly capacity. Rockley is dependent on the availability of this capacity to manufacture and assemble Rockley’s products and Rockley can provide no assurance that adequate capacity will be available to it in the future.

If Rockley or its suppliers do not maintain sufficient inventory or if they do not adequately manage their respective inventory, Rockley could lose sales or incur higher inventory-related expenses, which could negatively affect Rockley’s operating results.

To ensure adequate inventory supply, Rockley and its suppliers must forecast inventory needs and expenses, place orders sufficiently in advance with their respective suppliers and manufacturing counterparties, and manufacture products based on its estimates of future demand for particular products. Changes in customer purchasing patterns may affect Rockley’s ability to forecast its future operating results, including revenue, gross margins, cash flows, and profitability. Rockley’s ability to accurately forecast demand for its products could be affected by many factors, including the growth rate, if any, in Rockley’s target markets or the market adoption of the end products into which Rockley’s products are incorporated, the emergence of new markets, an increase or decrease in customer demand for Rockley’s products or for products and services of its competitors, product introductions by competitors, the COVID-19 pandemic, other health epidemics and outbreaks, and any associated work stoppages or interruptions, unanticipated changes in general market conditions, and the weakening of economic conditions or consumer confidence in future economic conditions. If Rockley’s products are commercialized in markets that are quickly growing, including the consumer wearables, mobile device, and medical device markets, Rockley may face challenges acquiring adequate supplies to manufacture its products and/or Rockley and its manufacturing counterparties may not be able to manufacture its products at a rate necessary to satisfy the levels of demand, which would negatively affect Rockley’s revenue. This risk may be exacerbated by the fact that Rockley may not carry or be able to obtain for its manufacturers a significant amount of inventory to satisfy short-term demand increases. If it fails to accurately forecast customer demand, Rockley may experience excess inventory levels or a shortage of products available for sale.

Inventory levels in excess of customer demand may result in inventory write-downs or write-offs and the sale of excess inventory at discounted prices, which would adversely affect Rockley’s financial results, including its gross margin, and have a negative effect on its brand. Conversely, if Rockley underestimates customer demand for its products, Rockley, or its manufacturing counterparties, may not be able to deliver products to meet its requirements, and this could result in damage to Rockley’s brand and customer relationships and adversely affect its revenue and operating results.

If Rockley’s products do not conform to, or are not compatible with, existing or emerging industry standards, demand for Rockley’s products may decrease, which in turn would harm Rockley’s business and operating results.

Rockley’s ability to compete in the future will depend on its ability to identify and ensure compliance with evolving industry standards in its target markets, as well as in the silicon photonics and sensing technology industry generally. The emergence of new industry standards could render Rockley’s products incompatible with products developed by third-party suppliers or make it difficult for Rockley’s products to meet the requirements of certain device manufacturers and their suppliers. If Rockley’s customers or Rockley’s third-party suppliers adopt new or competing industry standards with which Rockley’s solutions are not compatible, or if industry groups fail to adopt standards with which Rockley’s products are compatible, Rockley’s products would become less desirable to its current or prospective customers. As a result, Rockley’s sales would suffer and it could be required to make significant expenditures to develop new products. Although Rockley designs its products to be compliant with applicable industry standards, proprietary enhancements may not in the future result in conformance with existing industry standards under all circumstances. If Rockley’s products do not conform to, or are not compatible with, existing or emerging standards, it would harm its business, financial condition, and results of operations.

Rockley may be subject to warranty or product liability claims, which could result in unexpected expenses and loss of market share.

Rockley may be subject to warranty or product liability claims. These claims may require Rockley to make significant expenditures to defend those claims, replace Rockley’s solutions, refund payments, or pay damage awards. Rockley has not yet commercialized its products. Accordingly, the operation of Rockley’s products and technology has not been validated over longer periods. If a customer’s end product fails in use, the customer may incur significant monetary damages, including a product recall or associated replacement expenses as well as lost revenue. The customer may claim that a defect in Rockley’s product caused the product failure and assert a claim against Rockley to recover monetary damages. The cost of defending these claims and satisfying any arbitration award or judgment with respect to these claims would result in unexpected expenses, which could be substantial, and could harm Rockley’s business, financial condition, and results of operations. Although Rockley carries product liability insurance, this insurance is subject to significant deductibles and may not adequately cover Rockley’s costs arising from defects in its products or otherwise.

The complexity of Rockley’s products and its anticipated future product and service offerings could result in unforeseen delays or expenses from undetected defects, errors, or reliability issues in hardware or software that could reduce the market adoption of its new products, damage its reputation with current or prospective customers, and adversely affect its operating costs.

Rockley’s current and future products and service offerings are or are expected to be highly technical and very complex and require high standards to manufacture or distribute and have in the past and will likely in the future experience defects, errors, or reliability issues at various stages of development. Rockley may be unable to timely release new products, product updates, manufacture existing products, correct problems that have arisen, or correct such problems to its customers’ satisfaction. Additionally, undetected errors, defects, or security vulnerabilities, especially as new products or updates are introduced or as new versions are released, could result in inaccurate data to the end users of products incorporating Rockley’s products. Any of the foregoing could negatively impact Rockley’s ability to commercialize a product or service offering, result in litigation against Rockley, and damage

Rockley’s credibility. These risks may be heightened in the medical device industry, one of Rockley’s target markets, where the end user may act in reliance upon inaccurate data as a result of errors or defects, or where there may be a privacy or data breach of an end user’s personal health information. Some errors or defects in Rockley’s products and service offerings may only be discovered after they have been tested, commercialized, and deployed by customers. In these cases, Rockley may incur significant additional development costs and product recall, repair, or replacement costs. These problems may also result in claims, including class actions, against Rockley by its customers or others. Rockley’s reputation or brand may be damaged as a result of these problems and customers may be reluctant to buy its products, which could adversely affect its ability to retain existing customers and attract new customers and could adversely affect its financial results.

In addition to product liability claims, Rockley could face material legal claims for breach of contract, fraud, tort, or breach of warranty as a result of these problems. Defending a lawsuit, regardless of its merit, could be costly and may divert management’s attention and adversely affect the market’s perception of Rockley and its products. In addition, Rockley’s business liability insurance coverage could prove inadequate with respect to a claim and future coverage may be unavailable on acceptable terms or at all. These product-related issues could result in claims against Rockley and its business could be adversely affected.

Rockley currently expects to recognize subscription revenue from its future cloud-based analytics subscription offering ratably over the term of these subscriptions and, to a lesser extent, perpetual licenses ratably over an expected period of benefit and, as a result, downturns in sales may not be immediately reflected in its operating results.

If Rockley is able to commercially launch its cloud-based analytics subscription service, which is currently expected to occur as early as 2023, it expects to recognize revenue ratably over the terms of its subscriptions with customers. As a result, a substantial portion of the revenue that it will report in each period will be derived from the recognition of deferred revenue relating to agreements entered into during previous periods. Consequently, a decline in new sales or renewals in any one period may not be immediately reflected in its revenue results for that period. This decline, however, will negatively affect its revenue in future periods. Accordingly, the effect of significant downturns in sales and market acceptance of its subscription service and potential changes in the rate of renewals may not be fully reflected in its results of operations until future periods. This will also make it difficult for Rockley to rapidly increase revenue growth through additional sales in any period, as revenue from new customers generally will be recognized over the term of the applicable agreement. Rockley may be unable to commercially launch its subscription service offering in a timely manner or at all and such subscription offering may not achieve widespread customer adoption.

If Rockley’s future platform offerings do not interoperate with its customers’ network and security infrastructure or with third-party products, websites, or services, it would negatively impact its business and results of operations.

Rockley’s cloud-based analytics subscription offering, which is under development and is currently expected to be commercially launched as early as 2023, is expected to allow for the deployment of Rockley’s technology through a cloud-based software-as-a-service model. As a result, it must interoperate with Rockley’s customers’ existing network and security infrastructure. The components of Rockley’s customers’ infrastructure have different specifications, rapidly evolve, utilize multiple protocol standards, include multiple versions and generations of products, and may be highly customized. Rockley must be able to interoperate and provide its software service to customers with highly complex and customized networks, which requires careful planning and execution between its customers, its customer support teams, and its channel partners. Further, whenever there are new or updated elements of the customers’ infrastructure or new industry standards or protocols, Rockley may have to update or enhance its cloud platform to continue to provide service to customers. Rockley’s competitors or other vendors may refuse to work with Rockley to allow their products to interoperate with Rockley’s, which could make it difficult for Rockley’s cloud-based analytics subscription service to function properly in customer networks that include these third-party products.

Rockley may not deliver or maintain interoperability quickly or cost-effectively, or at all. If Rockley fails to maintain compatibility of its cloud-based analytics subscription service with its customers’ network and security infrastructures, its customers may not be able to fully utilize the service, and Rockley may, among other consequences, fail to achieve widespread customer adoption of this subscription service and experience reduced demand for its products and services, which would materially harm its business, operating results, and financial condition.

Rockley licenses technology from third parties, and its inability to maintain those licenses could harm its business.

Rockley incorporates technology that it licenses from third parties, including software, into its software subscriptions. Rockley cannot be certain that its licensors are not infringing the intellectual property rights of third parties or that its licensors have sufficient rights to the licensed intellectual property in all jurisdictions in which Rockley may sell its software subscriptions. In addition, some licenses may be non-exclusive, and therefore its competitors may have access to the same technology licensed to Rockley. Some of Rockley’s license agreements may be terminated for convenience by the licensors. Rockley may also be subject to additional fees or be required to obtain new licenses if any of its licensors allege that Rockley has not properly paid for such licenses or that it has improperly used the technologies under such licenses, and such licenses may not be available on terms acceptable to Rockley or at all. If Rockley is unable to continue to license any of this technology because of intellectual property infringement claims brought by third parties against its licensors or against it, or claims against Rockley by its licensors, or if Rockley is unable to continue its license agreements or enter into new licenses on commercially reasonable terms, its ability to develop and sell software

subscriptions containing such technology would be severely limited, and its business could be harmed. Additionally, if Rockley is unable to license necessary technology from third parties, it may be forced to acquire or develop alternative technology, which it may be unable to do in a commercially feasible manner or at all, and Rockley may be required to use alternative technology of lower quality or performance standards. This would limit and delay its ability to offer new or competitive software subscriptions and increase its costs of production. As a result, Rockley’s margins, market share, and operating results could be significantly harmed.

Portions of Rockley’s cloud-based analytics subscription offering utilize open source software, and any failure to comply with the terms of one or more of these open source licenses could negatively affect its business.

Rockley’s cloud-based analytics subscription offering contains software made available by third parties under so-called “open source” licenses. From time to time, there have been claims against companies that distribute or use open source software in their products and services, asserting that such open source software infringes the claimants’ intellectual property rights. Rockley could be subject to suits by parties claiming that what Rockley believes to be licensed open source software infringes their intellectual property rights. Use and distribution of open source software may entail greater risks than use of third-party commercial software, as open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. In addition, certain open source licenses require that source code for software programs that are subject to the license be made available to the public and that any modifications or derivative works to such open source software continue to be licensed under the same terms. Further, certain open source licenses also include a provision that if Rockley enforces any patents against the software programs that are subject to the license, it will lose the license to such software. If Rockley were to fail to comply with the terms of such open source software licenses, such failures could result in costly litigation, lead to negative public relations, or require that it quickly find replacement software which may be difficult to accomplish in a timely manner.

Although Rockley monitors its use of open source software in an effort both to comply with the terms of the applicable open source licenses and to avoid subjecting its software to conditions it does not intend, the terms of many open source licenses have not been interpreted by U.S. or international courts, and there is a risk that these licenses could be construed in a way that could impose unanticipated conditions or restrictions on its ability to commercialize its product or operate its business. By the terms of certain open source licenses, Rockley could be required to release the source code of its software and to make its proprietary software available under open source licenses, if Rockley combines or distributes its software with open source software in a certain manner. In the event that portions of its software are determined to be subject to an open source license, Rockley could be required to publicly release the affected portions of its source code, re-engineer all, or a portion of, that software or otherwise be limited in the licensing of its software, each of which could reduce or eliminate the value of its product. Many of the risks associated with usage of open source software cannot be eliminated, and could negatively affect its business, results of operations, and financial condition.

Customer-Related Risks

Rockley currently has, and intends to target, customers and suppliers that are large corporations with substantial negotiating power, exacting product, quality, and warranty standards, and potentially competitive internal solutions. If Rockley is unable to sell its products to these customers or is unable to enter into agreements with customers and suppliers on satisfactory terms, its prospects and results of operations will be adversely affected.

Many of Rockley’s customers and suppliers, and potential customers, are large corporations with substantial negotiating power relative to it and, in some instances, may have internal solutions that are competitive to Rockley’s products. Many of these large corporations that are customers or potential customers also have significant development resources, which may allow them to acquire or develop independently, or in partnership with others, competitive technologies. Meeting the technical requirements and securing design wins with any of these companies will require a substantial investment of Rockley’s time and resources. Rockley cannot assure you that its products or technology will secure design wins from these or other companies or that it will generate meaningful revenue from the sales of its products to these key customers and potential customers. If Rockley’s products are not selected by these large corporations or if these corporations develop or acquire competitive technology, it will have an adverse effect on Rockley’s business.

Rockley currently depends on a few large customers for a substantial portion of its revenue. The loss of, or a significant reduction in, orders from Rockley’s customers, including its largest customer, could significantly reduce its revenue and adversely impact Rockley’s operating results.

Rockley believes that its operating results for the foreseeable future will continue to depend to a significant extent on revenue attributable to a few large customers. Revenue attributable to Rockley’s largest customer accounted for the majority of its revenue in 2022 and 2021, respectively. Rockley anticipates revenue attributable to this customer will fluctuate from period to period, although it expects to remain dependent on this customer for a significant portion of its revenue for the foreseeable future. Rockley has a master supply and development agreement with this customer, which provides a general framework for Rockley’s transactions with it. This agreement continues until either party terminates for material breach. Under this agreement, Rockley has agreed to develop and deliver new products to this customer at its request, provided it also meets Rockley’s business purposes, and has agreed to indemnify it for intellectual property infringement or any injury or damages caused by Rockley’s products. This customer does not have any minimum or binding purchase obligations to Rockley under this agreement and could elect to discontinue or reduce making purchases from Rockley with little or no notice.

In addition, customers may seek to enter into licensing arrangements in lieu of product purchases, which could negatively impact Rockley’s revenue, and, to a lesser extent, Rockley’s gross margins. If Rockley’s customers were to choose to work with other manufacturers or its relationships with its customers is disrupted for any reason, it could have a significant negative impact on Rockley’s business. Any reduction in sales attributable to Rockley’s larger customers would have a significant and disproportionate impact on Rockley’s business, financial condition, and results of operations. Rockley’s customers, or the distributors through which it sells to these customers, may choose to use products in addition to Rockley’s, use a different product altogether, or develop an in-house solution. Any of these events could significantly harm its business, financial condition, and results of operations. In addition, if Rockley’s distributors’ relationships with Rockley’s end customers, including its larger end customers, are disrupted for inability to deliver sufficient products or for any other reason, it could have a significant negative impact on Rockley’s business, financial condition, and results of operations.

Rockley is dependent in part upon its relationships and alliances with industry participants to generate revenue, which involves risks and uncertainties.

Rockley has, and in the future may, acquire interests in joint ventures, which may subject Rockley to risk because, among other things, Rockley cannot exercise sole decision-making power and its partners may have different economic interests than Rockley has. There are additional risks involved in joint venture transactions. For example, as a co-investor in a joint venture, Rockley may not be in a position to exercise sole decision-making authority relating to the joint venture or other entity. As a result, the operations of any joint venture are subject to the risk that third parties may make business, financial, or management decisions with which Rockley does not agree, or the management of the joint venture may take risks or otherwise act in a manner that does not serve Rockley’s interests. Further, there may be a potential risk of impasse in some business decisions because Rockley may not be in a position to exercise sole decision-making authority. In such situations, it is possible that Rockley may not be able to exit the relationship because it may not have the funds necessary to complete a buy-out of the other partner or it may be difficult to locate a third-party purchaser for its interest. Because Rockley may not have the ability to exercise control over such operations, it may not be able to realize some or all of the benefits that it believes will be created from its involvement. In addition, there is the potential that a joint venture partner may become bankrupt or have divergent, conflicting, or inconsistent economic or business interests from Rockley. This could result in, among other things, exposing Rockley to liabilities of the joint venture in excess of its proportionate share of these liabilities. If any of the foregoing were to occur, Rockley’s business, financial condition, and results of operations could suffer.

If Rockley is unable to expand or further diversify its customer base, its business, financial condition, and results of operations could suffer.

Rockley currently expects the composition of its largest customers to vary over time, and that revenue attributable to its largest customers in any given period may decline over time. Rockley’s relationships with existing customers may deter potential customers who compete with these customers from buying Rockley’s products. If Rockley is unable to expand or further diversify its customer base, it could harm its business, financial condition, and results of operations.

Rockley does not currently have any products in commercial production. Accordingly, Rockley views its current customer relationships in the following stages: (a) customers with whom it is “engaged”, or in discussions with, regarding potential product features for incorporation into such customer’s end products or (b) customers with whom it is “contracted” where Rockley has non-binding MOUs or development and supply agreements. These non-binding MOUs and development and supply agreements provide a general framework for Rockley’s transactions with the customer and typically provide that Rockley will develop and deliver new products meeting the customer’s specifications. These agreements do not contain any minimum or binding purchase obligations. If Rockley is unable to transition customers with whom it is engaged in discussions to contracted customers or if Rockley fails to otherwise attract new customers, it would negatively impact Rockley’s ability to grow its business and gain market share, which in turn would harm Rockley’s financial condition and results of operations.

Because Rockley does not anticipate long-term purchase commitments with its customers, orders may be cancelled, reduced, or rescheduled with little or no notice, which in turn exposes Rockley to inventory risk, and may cause its business and results of operations to suffer.

Rockley anticipates that its products will be sold directly to customers as well as through distributors and resellers, with, in certain cases, no long-term or minimum purchase commitments from them or their end customers. Rockley expects that sales of its products will be primarily made pursuant to standard purchase orders, which orders may be cancelled, reduced, changed, or rescheduled with little or no notice or penalty. Cancellations of orders could result in the loss of anticipated sales without allowing Rockley sufficient time to reduce its inventory and operating expenses. In addition, changes in forecasts or the timing of orders from its customers expose Rockley to the risks of inventory shortages or excess inventory. As a result, Rockley’s revenue and operating results could fluctuate materially and could be materially and disproportionately impacted by purchasing decisions of Rockley’s customers, including Rockley’s larger customers. In the future, Rockley’s customers or its distributors or their end customers may decide to purchase fewer units than expected, may alter their purchasing patterns at any time with limited or no notice, or may decide not to continue to purchase Rockley’s products at all, any of which could cause Rockley’s revenue to decline materially and materially harm Rockley’s business, financial condition, and results of operations.

Cancellations of, reductions in, or rescheduling of customer orders could also result in the loss of anticipated sales without allowing Rockley sufficient time to reduce its inventory and operating expenses, as a substantial portion of Rockley’s expenses are fixed at least in the short term. In addition, changes in forecasts or the timing of orders expose Rockley to the risks of inventory shortages or excess inventory. Any of the foregoing events could materially and adversely affect Rockley’s business, financial condition, and results of operations.

If Rockley is unable to establish and maintain confidence in its long-term business prospects among customers and analysts and within its industry or is subject to negative publicity, then Rockley’s financial condition, operating results, business prospects, and access to capital may suffer materially.

Rockley has not yet fully developed or commercialized its products or services and the successful commercialization of Rockley’s products depends in part on Rockley’s customers and potential customers committing to use Rockley’s products in their own products. Customers may be less likely to purchase Rockley’s products if they are not convinced that Rockley’s business will succeed or that its service and support and other operations will continue in the long term. Similarly, suppliers and other third parties will be less likely to invest time and resources in developing business relationships with Rockley if they are not convinced that Rockley’s business will succeed. If Rockley is unable to establish and maintain confidence in its long-term business prospects among customers, suppliers, analysts, ratings agencies, and within its industry or is subject to negative publicity, then Rockley’s financial condition, operating results, business prospects, and access to capital may suffer materially.

Rockley’s investments in educating its customers and potential customers about the advantages of Rockley’s silicon photonics and sensing technology and its applications will require significant financial and talent resources and may not result in sales of Rockley’s products.

Educating Rockley’s prospective customers, and to a lesser extent, its existing customers, about Rockley’s silicon photonics and sensing technology and its applications in health monitoring devices, its advantages over competitive technologies, and the potential application of Rockley’s products in different industries and use cases is an integral part of Rockley’s strategy to expand into additional markets. Rockley’s efforts to educate potential customers and the market generally will require significant financial and talent resources. These educational efforts may not be successful and Rockley may not offset the costs of such efforts with revenue from the new customers. If Rockley is unable to acquire new customers to offset these expenses, its financial condition will be adversely affected.

Legal and Regulatory Risks Related to Rockley’s Business

Rockley is subject to governmental export and import control laws and regulations. Rockley’s failure to comply with these laws and regulations could have an adverse effect on its business, prospects, financial condition, and results of operations.

Certain of Rockley’s products and services are subject to export control and import laws and regulations, including the U.S. Export Administration Regulations, U.S. Customs regulations, and various economic and trade sanctions regulations administered by the U.S. Treasury Department’s Office of Foreign Assets Controls. U.S. export control laws and regulations and economic sanctions prohibit the shipment of certain products and services to U.S. embargoed or sanctioned countries, governments and persons. In addition, complying with export control and sanctions regulations for a particular sale may be time-consuming and result in the delay or loss of sales opportunities. Exports of Rockley’s products and technology must be made in compliance with these laws and regulations. If Rockley fails to comply with these laws and regulations, Rockley and certain of its employees could be subject to substantial civil or criminal penalties, including the possible loss of export or import privileges, fines, which may be imposed on Rockley and responsible employees or managers, and, in extreme cases, the incarceration of responsible employees or managers.

Changes to trade policy, tariffs, and import/export regulations may have a material adverse effect on Rockley’s business, financial condition, and results of operations.

Changes in global political, regulatory, and economic conditions, or in laws and policies governing foreign trade, manufacturing, development, and investment in the territories or countries where Rockley may purchase its components, sell its products, or conduct its business, could adversely affect Rockley’s business. The United States has in the past instituted or proposed changes in trade policies that included the negotiation or termination of trade agreements, the imposition of higher tariffs on imports into the United States, economic sanctions on individuals, corporations, or countries, and other government regulations affecting trade between the United States and other countries where Rockley conducts its business. For instance, effective December 17, 2021, the U.S. Bureau of Industry and Security (“BIS”) of the U.S. Department of Commerce placed Hengtong and certain of its affiliates on the BIS “Entity List,” meaning that the U.S. Export Administration Regulations prohibit companies from providing products and

technologies to organizations on the “Entity List” without prior authorization. In response to this decision, the Company terminated a planned technical sale to the JV. A number of other nations have proposed or instituted similar measures directed at trade with the United States in response. As a result of these developments or any future similar developments, there may be greater restrictions and economic disincentives on international trade and economic cooperation that could adversely affect Rockley’s business. It may be time-consuming and expensive for Rockley to alter its business operations to adapt to or comply with any such changes, and any failure to do so could have a material adverse effect on its business, financial condition, and results of operations.

Rockley may become involved in legal and regulatory proceedings and commercial or contractual disputes, which could have an adverse effect on its profitability and financial position.

Rockley may be, from time to time, involved in litigation, regulatory proceedings, and commercial or contractual disputes that may be significant. These matters may include, without limitation, disputes with Rockley’s suppliers and customers, intellectual property claims, shareholder litigation, government investigations, class action lawsuits, personal injury claims, environmental issues, customs and value-added tax disputes, and employment and tax issues. In addition, Rockley could face in the future a variety of labor and employment claims against it, which could include but is not limited to general discrimination, wage and hour, privacy, ERISA, or disability claims. In such matters, government agencies or private parties may seek to recover from Rockley indeterminate amounts in penalties or monetary damages (including, in some cases, treble or punitive damages) or seek to limit Rockley’s operations in some way. These types of lawsuits could require significant management time and attention or could involve substantial legal liability, adverse regulatory outcomes, and/or substantial expenses to defend. Often these cases raise complex factual and legal issues and create risks and uncertainties. No assurances can be given that any proceedings and claims will not have a material adverse impact on Rockley’s operating results and financial position or that its established reserves or its available insurance will mitigate this impact.

Rockley is subject to, and must remain in compliance with, numerous laws and governmental regulations across various jurisdictions concerning the use, distribution, and sale of its products. Some of Rockley’s customers also require that it comply with their own unique requirements relating to these matters.

Rockley sells products that contain electronic components, and such components may contain materials that are subject to government regulation in locations where Rockley sells its products. For example, certain regulations limit the use of lead in electronic components. Since Rockley operates on a global basis, compliance with regulations is a complex process which requires continual monitoring of regulations and an ongoing compliance process to ensure that Rockley and its suppliers are in compliance with existing regulations in each market where it operates. If there is an unanticipated new regulation that significantly impacts Rockley’s use and sourcing of various components or requires more expensive components, that regulation could materially and adversely affect its business, results of operations, and financial condition. Rockley’s products may also be used in healthcare monitoring and other medical devices, which are subject to additional regulation. If Rockley fails to adhere to these new regulations or fails to continually monitor the updates, it may be subject to litigation, loss of customers, or negative publicity and its business, results of operations, and financial condition will be adversely affected.

Rockley may in the future become subject to additional regulations, including Food and Drug Administration (the “FDA”) clearance or approval, for health monitoring products in which Rockley’s products are incorporated. Achieving and maintaining compliance and approval under applicable regulations may be difficult to achieve.

Rockley’s products may be incorporated into end products in the health monitoring sector, including products which collect clinical data. Accordingly, it is possible that certain of Rockley’s products, or the end products which incorporate Rockley’s products will be subject to current and future regulation by the FDA, as well as by other federal, state, and local agencies. As Rockley’s target market is consumer wellness rather than medical, Rockley currently anticipates that FDA clearance will be unnecessary for its products targeting the consumer wearables market; however, Rockley intends to monitor and comply with regulations to the extent they become applicable to Rockley.

Manufacturers of medical devices are required to comply with applicable laws and regulations governing development, testing, manufacturing, labeling, marketing, and distribution of medical devices. Devices are generally subject to varying levels of regulatory control, based on the risk level of the device. Governmental regulations specific to medical devices are wide-ranging and govern, among other things:

•

product design, development, and manufacture;

•

laboratory, pre-clinical and clinical testing, labeling, packaging, storage, and distribution;

•

premarketing clearance or approval;

•

record-keeping;

•

product marketing, promotion and advertising, sales, and distribution; and

•

post-marketing surveillance, including reporting of deaths or serious injuries and recalls and correction and removals.

Rockley or its customers may not be able to obtain the necessary clearances or approvals for their products or may be unduly delayed in doing so, which could harm Rockley’s business. Furthermore, even if Rockley is granted regulatory clearances or approvals, they may include significant limitations on the permitted uses for the product, which may limit the market potential for the product. Delays in obtaining clearance or approval could increase Rockley’s costs and harm Rockley’s revenue and growth.

Additionally, Rockley’s products may be subject to regulation by similar agencies in other states and foreign countries. While Rockley believes that it has complied with all applicable laws and regulations, continued compliance with such laws or regulations, including any new laws or regulations, might impose additional costs on Rockley which could adversely affect its financial performance and results of operations.

Rockley is subject to various environmental laws and regulations that could impose substantial costs upon Rockley.

Concerns over environmental pollution and climate change have produced significant legislative and regulatory efforts on a global basis, and Rockley believes this will continue both in scope and in the number of countries participating. In addition, as climate change issues become more prevalent, foreign, federal, state, and local governments and Rockley’s customers have been responding to these issues. The increased focus on environmental sustainability may result in new regulations and customer requirements, or changes in current regulations and customer requirements, which could materially and adversely impact Rockley’s business, results of operations, and financial condition. If Rockley is unable to effectively manage real or perceived issues, including concerns about environmental impacts or similar matters, sentiments toward Rockley or its products could be negatively impacted, and its business, results of operations, or financial condition could suffer.

Rockley’s operations are and will be subject to foreign, federal, state, and local environmental laws and regulations, and such laws and regulations could directly increase the cost of energy, which may have an effect on the way Rockley manufactures products or utilizes energy to produce its products. In addition, any new regulations or laws in the environmental area might increase the cost of raw materials or key components Rockley uses in its products. Environmental regulations require Rockley to reduce product energy usage, monitor and exclude an expanding list of restricted substances, and to participate in required recovery and recycling of its products. Environmental and health and safety laws and regulations can be complex, and Rockley has limited experience complying with them. Capital and operating expenses needed to comply with environmental laws and regulations can be significant, and violations may result in substantial fines and penalties, third-party damages, suspension of production, or a cessation of Rockley’s operations.

The costs of complying with environmental laws and regulations and any claims concerning noncompliance, or liability with respect to contamination in the future, could have a material adverse effect on Rockley’s financial condition or operating results. Rockley may face unexpected delays in obtaining the required permits and approvals in connection with its planned production facilities that could require significant time and financial resources and delay its ability to operate these facilities, which would adversely impact Rockley’s business, prospects, financial condition, and operating results.

Rockley is subject to U.S. and foreign anti-corruption and anti-money laundering laws and regulations. Rockley can face criminal liability and other serious consequences for violations, which can harm its business.

Rockley is subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act, the U.K. Bribery Act of 2010, and possibly other anti-bribery and anti-money laundering laws in countries in which Rockley conducts activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, contractors, and other collaborators from authorizing, promising, offering, or providing, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. Rockley can be held liable for the corrupt or other illegal activities of its employees, agents, contractors, and other collaborators, even if Rockley does not explicitly authorize or have actual knowledge of such activities. Any violations of the laws and regulations described above may result in substantial civil and criminal fines and penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm, and other consequences.

Failures, or perceived failures, to comply with privacy, data protection, and information security requirements in the variety of jurisdictions in which Rockley operates may adversely impact its business, and such legal requirements are evolving, uncertain, and may require improvements in, or changes to, Rockley’s policies and operations.

Rockley’s current and potential future operations and sales are subject to laws and regulations addressing privacy and the collection, use, storage, disclosure, transfer, and protection of a variety of types of data. For example, the European Commission has adopted the General Data Protection Regulation and California recently enacted the California Consumer Privacy Act of 2018, both of which provide for potentially material penalties for non-compliance. These regimes may, among other things, impose data security requirements, disclosure requirements, and restrictions on data collection, uses, and sharing that may impact Rockley’s operations and the development of its business. Rockley has limited access to collect, store, process, or share certain information collected by its products, and Rockley’s products may evolve to collect additional information. Therefore, the full impact of these privacy regimes on Rockley’s business is rapidly evolving across jurisdictions and remains uncertain at this time.

Rockley may also be affected by cyber-attacks and other means of gaining unauthorized access to its products, systems, and data. For instance, cyber criminals or insiders may target Rockley or third parties with which it has business relationships to obtain data, or in a manner that disrupts Rockley’s operations or compromises its products or the systems into which its products are integrated. Due to the political uncertainty involving Russia and Ukraine, there is an increased likelihood that escalation of tensions could result in cyber-attacks that could either directly or indirectly impact our operations.

Rockley is assessing the continually evolving privacy and data security regimes and measures it believes are appropriate in response. Since these data security regimes are evolving, uncertain, and complex, especially for a global business like Rockley, Rockley may need to update or enhance its compliance measures and these updates or enhancements may require implementation costs. In addition, Rockley may not be able to monitor and react to all developments in a timely manner. The compliance measures Rockley does adopt may prove ineffective. Any failure, or perceived failure, by Rockley to comply with current and future regulatory or customer-driven privacy, data protection, and information security requirements, or to prevent or mitigate security breaches, cyber-attacks, or improper access to, use of, or disclosure of data, or any security issues or cyber-attacks affecting Rockley, could result in significant liability, costs (including the costs of mitigation and recovery), and a material loss of revenue resulting from the adverse impact on its reputation and brand, loss of proprietary information and data, disruption to its business and relationships, and diminished ability to retain or attract customers and business partners. Such events may result in governmental enforcement actions and prosecutions, private litigation, fines, and penalties or adverse publicity, and could cause customers and business partners to lose trust in Rockley, which could have an adverse effect on its reputation and business.

Further, in the event Rockley’s products, or the end products into which Rockley’s products are incorporated, involve the collection of personal medical or clinical data, Rockley would be subject to additional privacy regulations. For example, the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”) regulations apply U.S. national standards for some types of electronic health information transactions and the data elements used in those transactions to ensure the integrity, security, and confidentiality of health information and standards to protect the privacy of individually identifiable health information businesses receive, maintain or transmit. The Health Information Technology for Economic and Clinical Health Act of 2009 (“HITECH Act”) expanded the scope of the privacy and security requirements under HIPAA and increased penalties for violations. In addition, the HITECH Act enacted federal breach notification rules requiring notification to affected individuals and the Department of Health and Human Services (and in some cases, relevant media outlets) whenever a breach of protected health information occurs. Rockley’s failure to maintain confidentiality of sensitive protected health information or other personal information in accordance with the applicable regulatory requirements could damage its reputation and expose Rockley to claims, fines, and penalties. Rockley’s business, operating results, and financial condition could also be negatively impacted by a violation of the HIPAA privacy or security rules or any other applicable privacy or data security law.

Many U.S. states and international jurisdictions in which Rockley operates also have laws and regulations that protect the privacy and security of confidential, protected health information, or other personal information and have similar or even more protection than U.S. federal regulations. Furthermore, state data breach notification laws continue to expand the type of protected health information and other personal information they encompass, and in many cases are more burdensome than the HIPAA/HITECH breach reporting requirements.

Risks Related to Rockley’s Intellectual Property

Despite the actions Rockley is taking to defend and protect its intellectual property, Rockley may not be able to adequately protect or enforce its intellectual property rights or prevent unauthorized parties from copying or reverse engineering its products or technology. Rockley’s efforts to protect and enforce its intellectual property rights and prevent third parties from violating its rights may be costly.

The success of Rockley’s products and its business depend in part on Rockley’s ability to obtain patents and other intellectual property rights and maintain adequate legal protection for its products in the United States and other international jurisdictions. Rockley relies on a combination of patent, trademark, and trade secret laws, as well as confidentiality procedures and contractual restrictions, to establish and protect its proprietary rights, all of which provide only limited protection.

Rockley cannot assure you that any patents will be issued with respect to its currently pending patent applications or that any trademarks will be registered with respect to its currently pending applications in a manner that gives Rockley adequate defensive protection or competitive advantages, if at all, or that any patents issued to Rockley or any trademarks registered by it will not be challenged, invalidated, or circumvented. Rockley may file for patents and trademarks in the United States and in certain international jurisdictions, but such protections may not be available in all countries in which it operates or in which Rockley seeks to enforce its intellectual property rights, or may be difficult to enforce in practice. For example, the legal environment relating to intellectual property protection in certain emerging market countries where Rockley may operate in the future is relatively weaker, often making it difficult to create and enforce such rights. Rockley’s currently registered trademarks and any patents and trademarks that may be issued or registered, as applicable, in the future with respect to pending or future applications may not provide sufficiently broad protection or may not prove to be enforceable in actions against alleged infringers. Rockley cannot be certain that the steps it has taken will prevent unauthorized use of its technology or the reverse engineering of its technology. Moreover, others may independently develop technologies that are competitive to Rockley or infringe Rockley’s intellectual property.

Protecting against the unauthorized use of Rockley’s intellectual property, products, and other proprietary rights is expensive and difficult, particularly internationally. Unauthorized parties may attempt to copy or reverse engineer Rockley’s sensing technology or certain aspects of Rockley’s products or manufacturing processes that it considers proprietary. Litigation may be necessary in the future to enforce or defend Rockley’s intellectual property rights, to prevent unauthorized parties from copying or reverse engineering its products, or technology to determine the validity and scope of the proprietary rights of others or to block the importation of infringing products into the United States.

Any such litigation, whether initiated by Rockley or a third party, could result in substantial costs and diversion of management resources, either of which could adversely affect Rockley’s business, operating results, and financial condition. Even if it obtains favorable outcomes in litigation, Rockley may not be able to obtain adequate remedies, especially in the context of unauthorized parties copying or reverse engineering its products or technology.

Further, many of Rockley’s current and potential competitors have the ability to dedicate substantially greater resources to defending intellectual property infringement claims and to enforcing their intellectual property rights than Rockley has. Attempts to enforce its rights against third parties could also provoke these third parties to assert their own intellectual property or other rights against Rockley or result in a holding that invalidates or narrows the scope of Rockley’s rights, in whole or in part. Effective patent, trademark, service mark, copyright, and trade secret protection may not be available in every country in which Rockley’s products are available and competitors based in other countries may sell infringing products in one or more markets. Failure to adequately protect Rockley’s intellectual property rights could result in Rockley’s competitors offering similar products, potentially resulting in the loss of some of Rockley’s competitive advantage and a decrease in its revenue, which would adversely affect Rockley’s business, operating results, financial condition, and prospects.

Third-party claims that Rockley is infringing intellectual property, whether successful or not, could subject Rockley to costly and time-consuming litigation or expensive licenses, and its business could be adversely affected.

Although Rockley has applied for patents related to its products and technology, a number of companies hold patents covering aspects of sensing and photonic chip technologies. In addition to these patents, participants in this industry typically also protect their technology, especially embedded software, through copyrights and trade secrets. As a result, there is frequent litigation based on allegations of infringement, misappropriation, or other violations of intellectual property rights. Rockley may in the future receive inquiries from other intellectual property holders and may become subject to claims that it infringes their intellectual property rights, particularly as Rockley expands its presence in the market, expands to new use cases, and faces increasing competition. In addition, parties may claim that the names and branding of Rockley’s products infringe their trademark rights in certain countries or territories. If such a claim were to prevail, Rockley may have to change the names and branding of its products in the affected territories and it could incur other costs.

Rockley currently has a number of agreements in effect pursuant to which it has agreed to defend, indemnify, and hold harmless its customers, suppliers, and channel partners and other counterparties from damages and costs which may arise from the infringement by Rockley’s products of third-party patents or other intellectual property rights. The scope of these indemnity obligations varies, and, in some instances, include indemnification for damages and expenses, including attorneys’ fees. Rockley’s insurance may not cover all intellectual property infringement claims. A claim that its products infringe a third party’s intellectual property rights, even if untrue, could adversely affect Rockley’s relationships with its customers, may deter future customers from purchasing its products, and could expose Rockley to costly litigation and settlement expenses. Even if Rockley is not a party to any litigation between a customer and a third party relating to infringement by its products, an adverse outcome in any such litigation could make it more difficult for Rockley to defend its products against intellectual property infringement claims in any subsequent litigation in which it is a named party. Any of these results could adversely affect Rockley’s brand and operating results.

Rockley may in the future need to initiate infringement claims or litigation to try to protect its intellectual property rights. In addition to litigation where Rockley is a plaintiff, Rockley’s defense of intellectual property rights claims brought against it or its customers, suppliers, and channel partners, with or without merit, could be time-consuming, expensive to litigate or settle, divert management resources and attention, and force Rockley to acquire intellectual property rights and licenses, which may involve substantial royalty or other payments and may not be available on acceptable terms or at all. Further, a party making such a claim, if successful, could secure a judgment that requires Rockley to pay substantial damages or obtain an injunction and also Rockley may lose the opportunity to license its technology to others or to collect royalty payments. An adverse determination also could invalidate or narrow Rockley’s intellectual property rights and adversely affect its ability to offer its products to its customers and may require that Rockley procure or develop substitute products that do not infringe, which could require significant effort and expense. Any of these events could adversely affect Rockley’s business, reputation, operating results, financial condition, and prospects.

Rockley’s intellectual property applications, including patent applications, may not be approved or granted or may take longer than expected to result in approval or grant, which may have a material adverse effect on Rockley’s ability to prevent others from commercially exploiting products similar to Rockley’s.

Rockley cannot be certain that it is the first inventor of the subject matter to which it has filed a particular patent application, or if it is the first party to file such a patent application. If another party has filed a patent application to the same subject matter as Rockley has, Rockley may not be entitled to the protection sought by the patent application. Rockley also cannot be certain whether the claims included in a patent application will ultimately be allowed in the applicable issued patent or the timing of any approval or grant of a patent application. Further, the scope of protection of issued patent claims is often difficult to determine. As a result, Rockley cannot be certain that the patent applications that it files will issue, or that its issued patents will afford protection against competitors with similar technology. In addition, Rockley’s competitors may design around Rockley’s registered or issued intellectual property, which may adversely affect Rockley’s business, prospects, financial condition, and operating results.

In addition to patented technology, Rockley relies on its unpatented proprietary technology, trade secrets, designs, experiences, workflows, data, processes, software, and know-how.

Rockley relies on proprietary information (such as trade secrets, designs, experiences, workflows, data, know-how, and confidential information) to protect intellectual property that may not be patentable or subject to copyright, trademark, trade dress, or service mark protection, or that Rockley believes is best protected by means that do not require public disclosure. Rockley generally seeks to protect this proprietary information by entering into confidentiality agreements, or consulting, services, or employment agreements that contain non-disclosure and non-use provisions with its employees, consultants, contractors, and third parties. However, these agreements may be breached or may otherwise fail to prevent disclosure, third-party infringement, or misappropriation of its proprietary information, may be limited as to their term, and may not provide an adequate remedy in the event of unauthorized disclosure or use of proprietary information. Rockley has limited control over the protection of trade secrets used by its current or future manufacturing counterparties and suppliers and could lose future trade secret protection if any unauthorized disclosure of such information occurs. In addition, Rockley’s proprietary information may otherwise become known or be independently developed by its competitors or other third parties. To the extent that its employees, consultants, contractors, advisors, and other third parties use intellectual property owned by others in their work for Rockley, disputes may arise as to the rights in related or resulting know-how and inventions. Costly and time-consuming litigation could be necessary to enforce and determine the scope of Rockley’s proprietary rights, and failure to obtain or maintain protection for its proprietary information could adversely affect its competitive business position. Furthermore, laws regarding trade secret rights in certain markets where Rockley operates may afford little or no protection to its trade secrets.

Rockley also relies on physical and electronic security measures to protect its proprietary information, but it cannot provide assurance that these security measures will not be breached or provide adequate protection for its property. There is a risk that third parties may obtain and improperly utilize Rockley’s proprietary information to its competitive disadvantage. Rockley may not be able to detect or prevent the unauthorized use of such information or take appropriate and timely steps to enforce its intellectual property rights.

Rockley may be subject to damages resulting from claims that it or its current or former employees have wrongfully used or disclosed alleged trade secrets of its current or former employees’ former employers. Rockley may be subject to damages if its current or former employees wrongfully use or disclose Rockley’s trade secrets.

Rockley may be subject to claims that it or its current or former employees have inadvertently or otherwise used or disclosed trade secrets or other proprietary information of a current or former employee’s former employers. Litigation may be necessary to defend against these claims. If Rockley fails to defend against such claims, in addition to paying monetary damages, it may lose valuable intellectual property rights or talent. A loss of key talent or their work product could hamper or prevent Rockley’s ability to commercialize its products, which could severely harm its business. Even if Rockley is successful in defending against these claims, litigation could result in substantial costs and demand on management resources.

Risks Related to Infrastructure, Cybersecurity and Privacy

A network or data security incident may allow unauthorized access to Rockley’s network or data, harm its reputation, create additional liability, and adversely impact its financial results.

Rockley and its third-party service providers may face security threats and attacks from a variety of sources. In addition to traditional computer “hackers,” malicious code (such as viruses and worms), phishing attempts, employee theft or misuse, and denial of service attacks, sophisticated nation-state and nation-state supported actors engage in attacks (including advanced persistent threat intrusions) and increase the risks to Rockley’s internal networks and customer facing environments and the information they store and process. These risks may increase due to COVID-19. A breach in Rockley’s data or an attack against its service availability, or that of its third-party service providers, could impact Rockley’s networks, creating system disruptions or slowdowns and exploiting security vulnerabilities of Rockley’s products, and the information stored on Rockley’s networks or those of its third-party service providers could be accessed, publicly disclosed, altered, lost, or stolen, which could subject Rockley to liability and cause it financial harm.

Unauthorized access by a third party to Rockley’s internal network, any actual or perceived breach of network security in its systems or networks, or any other actual or perceived data security incident Rockley or its third-party service providers suffer, could result in damage to its reputation, negative publicity, loss of channel partners, end-customers and sales, loss of competitive advantages over its competitors, increased costs to remedy any problems and otherwise respond to any incident, regulatory investigations and enforcement actions, costly litigation, and other liability. In addition, Rockley may incur significant costs to investigate and remediate any security breaches and other security incidents. Rockley’s data, corporate systems, third-party systems, and security measures may be breached due to the actions of outside parties, employee error, malfeasance, a combination of these, or otherwise, and, as a result, an unauthorized party may obtain access to its data. For example, in late 2020, Rockley was subject to phishing attacks, one involving a spoofed email whereby certain vendor account information was charged and payment was made to a fraudulent account and a second closely timed incident where a “forwarding” rule was applied to the spoofed email’s recipient. While no personal data was accessed and the issue was addressed, the incident resulted in a net loss of approximately $66,345, which loss has been accounted for in Rockley’s 2020 financial statements (which amount has been offset by a payout under our cybersecurity insurance policy in March 2021). While Rockley maintains cybersecurity insurance, such insurance may be insufficient to cover all liabilities incurred by these incidents, and any incidents may result in loss or increased costs of its cybersecurity insurance. Any of these negative outcomes could adversely impact the market perception of, and investor confidence in, Rockley.

Any disruption or performance issues with Rockley’s network infrastructure could harm its brand, reputation, and business.

Rockley has experienced, and may in the future experience, disruptions, outages, and other performance problems due to a variety of factors, including infrastructure changes, human or software errors, capacity constraints, and fraud. Any disruptions or other performance problems with Rockley’s products or reliability or security of Rockley’s systems could harm its reputation, brand, and Rockley’s business and operating results. In addition, Rockley must continually improve its computer network and infrastructure to avoid service interruptions or slower system performance. Rockley will need to devote additional resources to improving its platform architecture and its infrastructure. Any failure or delays in Rockley’s computer systems could cause service interruptions or slower system performance. These performance issues could harm Rockley’s business operations and financial condition.

Rockley relies on third parties to maintain and operate certain elements of its network infrastructure.

Rockley relies on third parties to operate and maintain certain elements of its network infrastructure. Interruptions in Rockley’s systems or the third-party systems on which it relies, whether due to system failures, computer viruses, physical or electronic break-ins, or other factors, could affect the security or availability of Rockley’s network infrastructure and website. Rockley’s existing data center facilities and third-party hosting providers have no obligations to renew their agreements with Rockley on commercially reasonable terms or at all, and certain of the agreements governing these relationships may be terminated by either party at any time, with no or limited notice. If any of these arrangements with third parties are terminated, Rockley could experience interruptions, as well as downtime, delays, and additional expenses in arranging alternative cloud infrastructure services. Rockley may incur significant liability from those customers and from third parties with respect to any breach of security affecting third parties’ infrastructure.

General Risks

The recurrence or continued effects of a global economic downturn as a result of the COVID-19 pandemic, political instability, and geopolitical conflicts could have an adverse effect on Rockley’s business and operating results.

Rockley operates globally and as a result its business and revenue are impacted by global macroeconomic conditions. The multinational efforts to contain the spread of COVID-19 had a significant adverse effect on the global macroeconomic environment. In addition, the instability in the global credit markets, uncertainties regarding the effects of Brexit, uncertainties related to the timing of the lifting of governmental restrictions to mitigate the spread of COVID-19, uncertainties related to changes in public policies such as domestic and international regulations, taxes, or international trade agreements, international trade disputes, government shutdowns, geopolitical turmoil such as the conflict between Russian and Ukraine, and other disruptions to global and regional economies and markets could continue to add uncertainty to global economic conditions. These adverse conditions could result in longer sales, development, and production cycles, slower adoption of new technologies, and increased price competition. As a result, any continued or further uncertainty, weakness, or deterioration in global macroeconomic and market conditions may cause Rockley’s customers to modify spending priorities or delay purchasing decisions, and result in lengthened sales, development, and production cycles, any of which could harm its business and operating results.

Overview

We have developed a unique sensing platform that we believe can reshape the wellness and healthcare industries through multiple applications in non-invasive, multi-modal biomarker monitoring. We believe products based on our technology platform could have the potential to unlock and accelerate advancements in areas such as early disease detection, nutrition management, and preventative healthcare delivery through continuous health and wellness monitoring.

To date, we have been engaged in developing customer-specific designs of our silicon photonics chipsets for incorporation into our customers’ end products. Accordingly, all of our products are presently in the development stage and we do not currently have any of our own end products in commercial production and have not yet shipped any products commercially. Our unique sensing platform has been built upon our silicon photonics technology, which enables compelling sensor performance, power, resolution, and density. This technology has the potential to allow monitoring devices, currently the size of clinical machines, to be condensed to the size of a wearable device. We believe this in turn has the potential to unlock additional uses in consumer electronics and medical devices. The resulting combination of technologies and manufacturing know-how is the “full-stack Rockley Platform” which is made up of PICs in silicon with integrated III-V devices (devices incorporating certain conductor elements that offer superior electronic properties, such as lasers), ASICs, photonic and electronic co-packaging, together with biosensing algorithms and AI cloud analytics, firmware/software, system architecture, and hardware design.

As testament to the relevance of our product development, we have captured the attention of several consumer electronics companies and, as of the date of this Annual Report on Form 10-K, we have established strategic relationships with six of the world’s top-ten largest manufacturers of smart watches and wristbands (based on volume as reported by IDC) and two of the five largest medtech companies (based on Becker’s ASC Review). We plan to leverage this attention to develop new capabilities in consumer wearables in the near term, and to expand over time into medical devices and other industry applications.

Our vision is to address many pressing healthcare concerns using our technology and we believe that there exists a large market opportunity for our platform. We estimate that the TAM for the consumer wearables, mobile device, and medical device markets is projected to be over $50 billion by 2025, based on data sourced from the Yole Report, the IDtexEx Report, the TrendForce Report, and our internal volume forecasts for smartphone, smart watch, and smart earbuds through 2025 (based on customer data), as the universe of healthcare and consumer wearable devices incorporating additional sensing capabilities emerges. Our target biomarkers for consumer healthcare include lactate, alcohol, glucose (indicator), carbon monoxide, blood pressure, blood oxygen, and core body temperature, among others. Our high-performance lasers have up to 1,000,000 times higher resolution, 1,000 times higher accuracy and 100 times broader range in wavelengths compared with existing LED offerings in wearable solutions (based on product analysis undertaken by Rockley comparing the Rockley silicon photonics-based spectrometer chip to existing solutions). In addition, as opposed to LED-based solutions, our lasers can be turned on more intermittently, and we employ dynamic adaptive power control to optimize laser on-time and overall power consumption for each different biomarker measurement, thus our solution will be more efficient than existing solutions.

We believe our platform will also be able to address existing applications in consumer wearable devices with significantly higher resolution, accuracy, and range. Further, we believe there are multiple additional markets and concrete opportunities for our technology platform in areas such as data center connectivity (optical transceivers), machine vision (robotic and automotive LiDAR), and compute connectivity (co-packaged optics, or CPO).

Following the completion of our product development phase and introduction of our products to the consumer and medtech wearable markets, we expect our revenue to be derived from sales of both high-volume consumer wearable products and wearables targeting medical applications. In addition, we plan to offer advanced module applications with biomarker detection capabilities for advanced health metrics that can detect and classify data that could potentially alert patients and healthcare providers to take preemptive action to prevent disease. We also expect to offer a cloud analytics platform to provide a full range of subscription services, including the deployment of our technology through a subscription and cloud-based software as a service

To date, we have generated revenue primarily from non-recurring engineering (“NRE”) and development services for customer-specific designs of silicon photonics chipsets for incorporation into their customers’ end products and we have financed our operations primarily through the Business Combination, issuance of convertible loan notes, as well as private placements of ordinary shares. For the year ended December 31, 2022, we incurred a net loss of $224.0 million and utilized $126.2 million in cash to fund our operations.

We expect both our capital and operating expenditures will increase significantly in connection with our ongoing activities, as we:

•

continue to invest in our technology and our silicon photonics solutions;

•

continue to develop innovative solutions and applications for our technology;

•

commercialize our silicon photonics solutions;

•

continue to invest in our sales and marketing activities and distribution channels;

•

invest and improve our operational, financial, and management information systems;

•

retain key talent and increase our headcount;

•

maintain and expand our intellectual property portfolio

Impact of COVID-19

The COVID-19 pandemic has nearly reached the three-year mark and our priority continues to be the health and safety of our employees. The overall recovery from the COVID-19 pandemic has been uneven and has presented many challenges and risks from general economic uncertainty, changes in consumer demand, disruption of supply chains, challenges with hiring, and labor and supply cost inflation. However, as we implemented our phased return to office plan starting in July 2021, we were able to provide greater levels of work flexibility to employees and maintain health and safety standards for employees meeting all regulatory requirements.

We continually evaluate the nature and extent of changes to the market and economic conditions related to the COVID-19 pandemic and assess the potential impact on our business and financial position. Despite the emergence of vaccines and vaccine boosters, the end of the COVID-19 pandemic is still uncertain. As such, we expect that the pandemic may continue to have an effect on our results, although the magnitude, duration, and full effects of the pandemic on our future results of operations or cash flows remain difficult to predict at this time.

For more information on risks associated with the COVID-19 pandemic and regulatory actions, see “Risk Factors — General Risks.”

Business Combination and Public Company Costs

As described in “Note 1 – Description of Business and Significant Accounting Policies” and “Note 2 – Note 2 – Business Combination” of the notes to the consolidated financial statements, we completed the Business Combination on August 11, 2021, with Legacy Rockley surviving the Business Combination as a wholly owned subsidiary of the Company.

Prior to the Business Combination, Legacy Rockley financed its operations primarily from the issuance of convertible loan notes and private placements of ordinary shares.

Upon the consummation of the Business Combination, we issued 104.0 million shares of ordinary shares for all the issued and outstanding equity interests of Legacy Rockley inclusive of ordinary shares issued in exchange for the issued and outstanding convertible loan notes (inclusive of interest accrued thereon) and warrants, as if each had converted into the Company’s ordinary shares immediately prior to the Business Combination. In addition, certain accredited investors (including entities affiliated with the SC Health Sponsor) purchased an aggregate of 15.0 million ordinary shares for a purchase price of $10.00 per share, or an aggregate purchase price of $150.0 million. The net cash received from the Business Combination after underwriter and transaction costs was $122.5 million.

•

Legacy Rockley’s existing shareholders hold a majority voting interest in the combined company, and as such, have the power to appoint a majority of the members of the Company’s Board;

•

Legacy Rockley’s senior management team comprise the majority of the senior management of the combined company;

•

Legacy Rockley is the larger of the companies based on historical operating activity and employee base; and

•

Legacy Rockley’s operations comprise the ongoing operations of the combined entity.

Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Legacy Rockley with the acquisition being treated as the equivalent of Rockley issuing stock for the net assets of SC Health, accompanied by a recapitalization.

As a consequence of the Business Combination, the Company became an SEC-registered and NYSE-listed company, which requires us to hire additional talent and implement procedures and processes to address public company regulatory requirements and customary practices. We expect to incur incremental annual expenses as a public company for, among other things, increased directors’ and officers’ liability insurance; director fees; and additional internal and external accounting, legal, and administrative resources.

Key Factors Affecting Operating Results

We believe that our performance and future success depend on several factors that present significant opportunities for us but also pose risks and challenges, including, without limitation, the following:

Resource Constraints

Our products are currently under development and we do not have any products in commercial production. Our ability to achieve our product roadmaps and development timelines, including our ability to commence commercial production of our products, may be impacted by resource constraints, including the need for additional capital. We have a history of losses and our determination of substantial doubt as a going concern could materially limit our ability to raise additional funds through the issuance of equity securities or otherwise. Further, our products must also meet certain technical standards and customer requirements, which in turn require additional funds and other resources. Additional financing and resources may not be available to us when needed or on commercially reasonable terms.

Ability to Achieve Design Wins or Long-Term Production Contracts

We may engage in discussions with customers and co-develop products but we may not be able to convert the relationship into a design win or a long-term production contract due to resource constraints, delays, or technical challenges. We work closely with our customers and potential customers to understand their product roadmaps and strategies. Our customers also continuously develop new products in existing and new application areas. We believe achieving design wins and the ability to secure long-term

production contracts will be critical to our future success. The selection process is typically lengthy and may require us to incur significant design and development expenditures in pursuit of a design win with no assurance that our products will be selected. The failure to secure a design win or long-term production contract could adversely affect our business.

Customer Orders and Forecasts

We currently anticipate that sales of our future products will be made pursuant to standard purchase orders, which may be cancelled, reduced, or rescheduled with little or no notice and without penalty. Cancellations of orders could result in the loss of anticipated sales without allowing us sufficient time to reduce our inventory and operating expenses. In addition, changes in forecasts or the timing of orders from customers, including if and when we commence commercial production of our products, could expose us to the risks of inventory shortages or excess inventory.

Pricing and Customer Demand

We expect our operating results, including if and when we commence commercial production of our products, will be impacted by the pricing of our products, our average selling prices, and fluctuations in customer purchasing volumes. If and when we begin commercial production of our products, we may not be able to fulfill customer demand in a timely manner or at all. We monitor and work to reduce our product manufacturing costs and improve the potential value our products can provide to our customers’ end products. The cost of raw materials and components critical for the manufacture of our anticipated products is largely out of our control and may fluctuate significantly. Since we rely on third-party wafer foundries and assembly and test contractors to manufacture, assemble, and test our products, we maintain a close relationship with our suppliers to improve quality, increase yields, and lower manufacturing costs.

New Markets and Applications

As we evaluate potential markets and applications for the products we are developing, we analyze forecasts by industry analysts, the adoption curve of technology, and potential competing forces that could hinder such adoption. If we fail to anticipate or respond to technological shifts or market demands, or to timely develop products or technologies in response to the same, it could result in our inability to achieve revenue growth and could harm our business and operations.

Cyclical Nature of the Semiconductor Industry

The semiconductor industry is highly cyclical and is characterized by constant and rapid technological change, rapid product obsolescence, price erosion, evolving standards, short product life cycles, and wide fluctuations in product supply and demand. Downturns in the semiconductor industry have been characterized by diminished product demand, production overcapacity, high inventory levels, and accelerated erosion of average selling prices. Any prolonged or significant downturn in the semiconductor industry generally could adversely affect our business and reduce demand for our products and otherwise harm our financial condition and results of operations.

See the “Risk Factors” section of this annual report on Form 10-K for additional discussion of the risks and challenges facing our business.

Basis of Presentation

Currently, we conduct business through one operating and reportable segment. All long-lived assets are maintained in, and all losses are attributable to the one segment. See Note 1 in our accompanying audited consolidated financial statements for more information about our operating segment.

Components of Results of Operations

The following discusses certain line items in our consolidated statements of operations.

Revenue

To date, we have primarily generated revenue from development services, which entail developing customer-specific designs of silicon photonics chipsets. Our contracts with customers include specific achievement of agreed-upon projects and a substantive acceptance criteria for each agreed-upon project. In the event an agreed-upon project is successful and the customer provides acceptance, we allocate the contract consideration related to the performance obligations that are satisfied during the period and recognize the revenue at that point in time.

Following the completion of our product development phase and introduction of our spectra-sense chipsets to the wearable devices market, we expect the majority of our revenue to be derived from sales of high-volume consumer wearable products. In addition, we plan to offer advanced module applications with biomarker detection capabilities for advanced health metrics that can detect, classify, and potentially prevent disease. We also expect to offer a cloud analytics platform to provide a full range of subscription services, including the deployment of our technology through a subscription and cloud-based software as a service.

Cost of Revenue

To date, our cost of revenue has included cost related to our development services, which include cost of materials, cost associated with packaging and assembly, testing and shipping, cost of talent, including stock-based compensation, and equipment associated with manufacturing support, logistics, and quality assurance, overhead, and occupancy costs. Once we commence commercial production of our silicon photonics chipsets, cost of revenues will include direct parts, material, and labor costs, manufacturing overhead, including amortized tooling costs, shipping and logistics costs, and reserves for estimated warranty expenses.

Gross Profit and Gross Margin

Gross profit is calculated based on the difference between our revenue and cost of revenue. Gross margin is the percentage obtained by dividing gross profit by our revenue. As we approach commercial production of spectra-sense chipsets, advanced module applications, and Rockley Photonics Cloud Analytics technology, we expect our gross profit and gross margin to vary.

Selling, General, and Administrative Expense

Selling, general, and administrative expenses consist of human capital related expenses for employees involved in general corporate functions, including executive management and administration, accounting, finance, tax, legal, information technology, marketing, and human resources; depreciation expense and rent relating to facilities; travel costs; professional fees; and other general corporate costs. Human capital expenses primarily include salaries, benefits, bonuses, and stock-based compensation.

Research and Development Expense

Research and development expense consists primarily of talent costs for engineers and third parties engaged in the design and development of products, software, and technologies, including salary, bonus, and stock-based compensation expense, project material costs, services, and depreciation of our research and development facilities and equipment. We expense research and development costs as they are incurred. Research and development expense also includes the research and development tax credits that we are able to claim in accordance with the relevant U.K. tax legislation. These tax credits are payable to us in cash and are carried on the consolidated balance sheets at the amount claimed and expected to be received from the U.K. government within the next 12 months. We expect research and development expense to increase in absolute dollars as we continue to invest in the development of our products and technology.

Other Income (Expense)

Other income consists of miscellaneous non-operating items, such as forgiveness of debt and related accrued interest.

Interest Income (Expense)

Interest income consists primarily of interest received or earned on our cash, cash equivalents, and investment balances held in interest-bearing deposit accounts. Interest expense consists of interest paid on our convertible loan notes and capital lease obligations.

Equity Method Investment

Equity method investments consist of entities over which we have significant influence but not control or joint control. Under the equity method of accounting, all of our investments are initially recognized at cost and adjusted thereafter to recognize our share of the post-acquisition profits or losses of the investee in our consolidated statements of operations.

Change in Fair Value of Debt Instruments

Gains or losses from the change in fair value of debt instruments are recorded from the remeasurement of the fair value of our convertible loan notes using a discounted cash flow methodology based upon certain valuation assumptions.

Change in Fair Value of Warrant Liabilities

Gains or losses from the change in fair value of warrants are recorded from the remeasurement of the fair value of our private placement warrants, public warrants and warrants issued in connection with certain convertible notes based upon certain valuation assumptions.

Gain (Loss) on Foreign Currency

We have significant international operations that are denominated in foreign currencies, primarily the British Pound and Euro, subjecting us to foreign currency exchange risk that may adversely impact our financial results. We calculate the year-over-year impact of foreign currency movement on our business using foreign currency exchange rates that are applied to transactional currency amounts.

Provision for Income Tax

We are subject to income taxes in the United Kingdom, the United States, Finland, Ireland, and Switzerland. Our income tax provision consists of an estimate of federal, state, and foreign income taxes based on enacted federal, state, and foreign tax rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in the valuation of our deferred tax assets and liabilities, and changes in tax laws. Due to cumulative losses, we maintain a valuation allowance against our U.S. federal and foreign deferred tax assets.

NM – Not meaningful

Cost of revenue decreased by $3.0 million, or 26%, to $8.5 million for the year ended December 31, 2022 from $11.4 million for the year ended December 31, 2021. This decrease in cost of revenue was primarily driven by an overall decrease in revenue and decrease in allocation of costs related to revenue generating activities when compared to the prior year.

Gross profit decreased by $2.0 million to $(5.2) million for the year ended December 31, 2022 from $(3.2) million for the year ended December 31, 2021. The decrease in gross profit was primarily driven by a decrease in revenue for the year ended December 31, 2022.

Our gross margin has fluctuated and may fluctuate from period to period based on a number of factors, including the timing of completion of project milestones, with each project requiring differing levels of time and costs. The projects we undertake are determined by our customer commitments and our long-term strategy goals.

To date, our cost of revenue has included cost related to our development services which include cost of materials, cost associated with packaging and assembly, testing and shipping, cost of talent, including stock-based compensation, and equipment associated with manufacturing support, logistics, and quality assurance, overhead, and occupancy costs. Once we commence commercial production of our silicon photonics chipsets, cost of revenues will include direct parts, material, and labor costs, manufacturing overhead, including amortized tooling costs, shipping and logistics costs, and reserves for estimated warranty expenses.

Selling, General and Administrative Expenses (in thousands, except for percentages)


	Years Ended December 31,				Change
	2022		2021		$		%

Selling, general and administrative expenses	$	61,532	$	39,976	$	21,556		54	%

Selling, general and administrative expenses increased by $21.6 million, or 54%, to $61.5 million for the year ended December 31, 2022 from $40.0 million for the year ended December 31, 2021. The increase was primarily due to an increase in professional fees of $16 million related to our financing activities in fiscal 2022. Further, the increase relates general corporate growth, of which $2.9 million was due to an increase in insurance expense, $1.6 million and $0.6 million were due to increased human capital and stock-based compensation costs, respectively.

Research and Development Expenses (in thousands, except for percentages)


	Years Ended December 31,				Change
	2022		2021		$		%

Research and development expenses	$	103,095	$	72,573	$	30,522		42	%

Research and development expenses increased by $30.5 million, or 42%, to $103.1 million for the year December 31, 2022 from $72.6 million for the year ended December 31, 2021. The increase was primarily attributable to an increase in stock-based compensation expenses of $1.7 million, higher IT infrastructure costs of $1.4 million, higher third party engineering costs of $5.1 million and a decrease in allocation of expenses of $7.9 million to R&D and a decrease in the R&D tax credit of $16.6 million.

Research and development expense consists primarily of talent costs for engineers and third parties engaged in the design and development of products, software, and technologies, including salary, bonus, and stock-based compensation expense, project material costs, services, and depreciation of our research and development facilities and equipment. We expense research and development costs as they are incurred. Research and development expense also includes the research and development tax credits that we are able to claim in accordance with the relevant U.K. tax legislation. These tax credits are payable to us in cash and are carried on the consolidated balance sheets at the amount claimed and expected to be received from the U.K. government within the next 12 months. We proactively manage research and development expense whilst remaining focused in the development of our products and technology.

Other income, net (in thousands, except for percentages)


	Years Ended December 31,					Change
	2022			2021		$			%
Other income, net	$	(348	)	$	2,860	$	(3,208	)		(112	)%

The decrease in other income, net, for the year ending December 31, 2022 compared to the year ending December 31, 2021, is attributable to the absence of the forgiveness of Paycheck Protection Program debt and related accrued interest which only occurred in fiscal 2021.

Interest Expense, net (in thousands, except for percentages)


	Years Ended December 31,						Change
	2022			2021			$			%
Interest expense, net	$	(14,697	)	$	(4,781	)	$	(9,916	)		207	%

The change in interest expense, net by $9.9 million, or 207%, for the years ended December 31, 2022 and December 31, 2021, respectively was primarily due to the interest expense recorded in fiscal 2022 due to the imputed interest expense from the 2020 Term Facility Loan and interest on the May and October Notes.

Interest income consists primarily of interest received or earned on our cash, cash equivalents, and investment balances held in interest-bearing deposit accounts. Interest expense consists of interest paid or accrued on our Term Facility Loan and May and October Notes.

Equity Method Investment Loss (in thousands, except for percentages)


	Years Ended December 31,						Change
	2021			2020			$		%
Equity method investment loss	$	(523	)	$	(703	)	$	180		(26	)%

Change in equity method investment captures our share of losses of the investment in HRT according to our percentage of ownership.

Change in Fair Value of Debt Instruments (in thousands, except for percentages)


	Years Ended December 31,						Change
	2022			2021			$			%
Change in fair value of debt instruments	$	(73,361	)	$	(59,916	)	$	(13,445	)		22	%

Change in fair value of debt instruments captures losses from a change in fair value estimates using discounted cash flow and binomial lattice methodologies that are based upon a set of valuation assumptions to value the May and October Notes.

All convertible debt instruments held by the Company prior to the Business Combination in August 2021 were converted to ordinary shares in the Company as part of the close of the Business Combination in August 2021.

Change in Fair Value of Warrant Liabilities (in thousands, except for percentages)


	Years Ended December 31,				Change
	2022		2021		$		%
Change in fair value of warrant liabilities		44,138	$	10,827	$	33,311		308	%

Change in fair value of warrant liabilities captures activity from a change in fair value estimates based upon a set of Black-Scholes valuation assumptions or binomial lattice methodologies. The warrant liabilities include the Private Placement Warrants assumed from SC Health as part of the Business Combination in August 2021 and the May 144A Warrants issued by the Company in May 2022 and the October 144A Warrants issued by the Company in October 2022.

Gain (Loss) on Foreign Currency (in thousands, except for percentages)


	Years Ended December 31,					Change
	2022			2021		$			%
Gain (loss) on foreign currency	$	(5,905	)	$	119	$	(6,024	)		(5,062	)%

Change in gain (loss) on foreign currency captures losses from the impact of foreign currency exchange rates as a result of the translation of foreign functional currencies into our reporting currency and the re-measurement of foreign currency transactions and balances. For the years ended December 31, 2022 and 2021, most of our balances are held in the reporting currency, which decrease the impact of foreign currency fluctuations on the results of our operations.

Provision for Income Tax (in thousands, except for percentages)


	Years Ended December 31,				Change
	2022		2021		$		%
Provision for income tax	$	3,504	$	667	$	2,837		425	%

Change in provision for income tax expense for the years ended December 31, 2022 and 2021 is due primarily to changes in U.S. tax laws which required capitalization of certain research and development expenditures for tax purposes. Our effective tax rate differs from the U.K. statutory rate primarily due to a substantially full valuation allowance against our net deferred tax assets where it is more likely than not that some or all of the deferred tax assets will not be realized. The income tax expenses shown above are primarily related to corporate income taxes in the United States, which operates on a cost-plus arrangement and minimum filing fees in the foreign jurisdictions where we have operations.

Liquidity and Capital Resources

Due to Rockley’s history of recurring losses from operations, negative cash flows from operations, and a significant accumulated deficit, and the Chapter 11 bankruptcy petition filed in January 2023, management concluded that there is substantial doubt about Rockley’s ability to continue as a going concern. In addition, our independent registered public accounting firm has included an explanatory paragraph in their opinion for the year ended December 31, 2022 as to the substantial doubt about our ability to continue as a going concern. Since inception, Rockley has financed its operations primarily through the issuance and sale of convertible loan notes, ordinary shares and agreed-upon projects. As of December 31, 2022, the Company had cash, cash equivalents and investments of approximately $23.0 million.

Short-Term and Long-Term Liquidity Requirements

In October 2021, the Company entered into an equity line of credit arrangement (“ELOC”) with Lincoln Park Capital Fund, LLC, an Illinois limited liability company (“LPCF”). The ELOC is a private placement with registration rights, providing LPCF the ability to purchase up to 7.8 million of the Company’s ordinary shares for up to $50.0 million over 24 months. Proceeds from the sale of shares will go towards the Company to be used for working capital.

On May 27, 2022, the Company issued the May Notes in an aggregate principal amount of $81.5 million pursuant to the May Indenture, dated as of May 27, 2022, among the Company, certain of its subsidiaries, as guarantors, and Wilmington Savings Fund Society, FSB, as trustee and as collateral agent in a private placement financing and in connection therewith agreed to comply with the affirmative and negative covenants contained in the May Indenture, including a covenant that requires the Company to pledge at all time at least $20.0 million of cash and cash equivalents to secure the May Notes. This minimum cash and cash equivalents requirement potentially limits the Company’s liquidity position. See “Risk Factors — We are subject to restrictive debt covenants that limit our ability to finance our future operations and capital needs and to pursue business opportunities and activities.” for a discussion of risks related to restrictive covenants in the May Indenture.

On October 25, 2022, the Company issued the May Notes in an aggregate principal amount of $90.6 million pursuant to the October Indenture, dated as of October 25, 2022, among the Company, certain of its subsidiaries, as guarantors, and Wilmington Savings Fund Society, FSB, as trustee and as collateral agent in a private placement financing and in connection therewith agreed to comply with the affirmative and negative covenants contained in the October Indenture, including a covenant that requires the Company to have a minimum amount of cash and cash equivalents of $5.0 million (including amounts in escrow) through December 29, 2022 and $20.0 million thereafter to secure the October Notes. This minimum cash and cash equivalents requirement potentially limits the Company’s liquidity position. See “Risk Factors — We are subject to restrictive debt covenants that limit our ability to finance our future operations and capital needs and to pursue business opportunities and activities.” for a discussion of risks related to restrictive covenants in the October Indenture.

As of the date of this Annual Report on Form 10-K, we have yet to generate any material revenue from our business operations. In addition, we have substantial debt obligations and limited liquidity. If we are unable to pay our obligations as they become due, our creditors could exercise their remedies under our debt agreements, which could include seizing control of our bank accounts, which in turn could require us to initiate bankruptcy proceedings. These actions could have the effect of substantially reducing or completely eliminating the value of our ordinary shares. You should not invest in our ordinary shares unless you are willing and able to withstand the complete loss of your investment.

On January 23, 2023, the Company filed a voluntary petition for relief under chapter 11 of title 11 (the “Chapter 11 Case”) of the United States Code (the “Bankruptcy Code”) in the United States Bankruptcy Court for the Southern District of New York (the “Bankruptcy Court”). The Company filed motions with the Bankruptcy Court seeking authorization to continue operating its business as a “debtor in possession” under the jurisdiction of the Bankruptcy Court and in accordance with the applicable provisions of the Bankruptcy Code and the orders of the Bankruptcy Court. The Company filed a series of first day motions with the Bankruptcy Court that sought authorization to continue conducting its business without interruption. These motions were designed primarily to minimize the effect of bankruptcy on the Company’s operations and were subsequently approved by the Bankruptcy Court. None of Rockley’s subsidiaries have filed voluntary petitions for relief under the Bankruptcy Code. The Company also filed the Prepackaged Chapter 11 Plan of Reorganization of Rockley Photonics Holdings Limited (as amended, supplemented, or modified from time to time, the “Plan”) and a related disclosure statement (the “Disclosure Statement”).. The Company sought expedited approval of the Plan as part of a comprehensive restructuring to de-lever the Company’s consolidated balance sheet by eliminating existing debt and introducing a new capital structure that would provide approximately $35 million of cash for ongoing operations. On January 24, 2023, the Company filed a petition with the Grand Court of the Cayman Islands seeking the appointment of joint restructuring officers to advise the Company and facilitate the restructuring transactions to be effectuated in connection with the Chapter 11 Case.

The filing of the Chapter 11 Case described above constituted an event of default or otherwise triggered repayment obligations under a number of instruments and agreements relating to direct financial obligations of the Company and certain of its subsidiaries. The May Notes and the October Notes each provide that, as a result of the Chapter 11 Case, the principal, accrued and unpaid interest and certain other amounts due thereunder, including certain prepayment premiums payable, shall be immediately due and payable. Any efforts to enforce such payment obligations under the Debt Instruments as to the Company were automatically stayed as a result of the Chapter 11 Case, and the Company’s creditors’ rights of enforcement in respect of the Debt Instruments are subject to the applicable provisions of the Bankruptcy Code and the Bankruptcy Court’s orders.

On March 10, 2023, the Bankruptcy Court approved the adequacy of the Disclosure Statement and confirmed the Plan. The Plan became effective March 14, 2023 (the “Effective Date”).

Pursuant to the Plan, after the Effective Date, the Company will liquidate pursuant to Cayman Islands law. Holders of existing equity interests in the Company will not receive or retain any distribution or property on account of such equity interests. In connection with the liquidation, the Company expects to file a Form 15 with the Securities and Exchange Commission to terminate the registration of its ordinary shares. Thereafter, the Company’s reporting obligations under the Securities Exchange Act of 1934, as amended shall be terminated.

Off-Balance Sheet Arrangements

Since the date of our incorporation, we have not engaged in any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Recent Accounting Pronouncements

Please refer to Note 1—Description of Business and Significant Accounting Policies of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for more information about recent accounting pronouncements, the timing of their adoption, and our assessment, to the extent we have made one, of their potential impact on our financial condition and our results of operations.

Critical Accounting Policies and Estimates

Our financial statements have been prepared in accordance with GAAP as set forth in the Financial Accounting Standards Board’s Accounting Standards Codification, and we consider the various staff accounting bulletins and other applicable guidance issued by the SEC. The preparation of our consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported expenses incurred during the reporting periods. Our estimates are based on our historical experience and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying value of assets and liabilities that are not readily apparent from other sources. Our actual results may differ from these estimates under different assumptions or conditions. To the extent that there are material differences between these estimates and our actual results, our future financial statements will be affected. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates.

See Note 1—Description of Business and Significant Accounting Policies of the Notes to Consolidated Financial Statements included in Item 8 of this Annual Report on Form 10-K for a summary of our significant accounting policies and the effect on our financial statements.

Revenue Recognition

We generate revenue principally from development services, which entails developing customer-specific designs of photonics chipsets. Our contracts with customers include specific achievement milestones and a substantive acceptance criteria for each milestone. In the event a milestone is achieved and the customer provides acceptance, the Company allocates the contract consideration related to the performance obligations that are satisfied during the period and recognizes the revenue at that point in time.

Stock-based Compensation

We recognize the cost of stock-based awards granted to our employees and directors based on the estimated grant-date fair value of the awards. Cost is recognized on a straight-line basis over the service period, which is generally the vesting period of the award. We have elected to recognize the effect of forfeitures in the period they occur. We determine the fair value of stock options using the Black-Scholes option pricing model, which is impacted by the following assumptions:

•

Expected Term—This is the period that the awards that have been granted are expected to remain unexercised. The Company employs the average period the awards are expected to remain outstanding;

•

Volatility—Our stock was not publicly traded prior to August 11, 2021. The volatility used in stock grants made prior to that date was based on a benchmark of comparable companies within the silicon photonics industries;

•

Risk-Free Interest Rate—The interest rates used are based on the implied yield available on U.S. Treasury zero-coupon issues with an equivalent remaining term equal to the expected life of the award; and

•

Dividend Yield—The dividend rate used is zero as we have never paid any cash dividends on our ordinary shares and do not anticipate doing so in the foreseeable future.

Following the Business Combination, the fair value of our ordinary shares is now determined based on the quoted market price. Prior to the Business Combination, our management and board of directors considered various objectives and subjective factors to determine the fair value of Legacy’s Rockley ordinary shares as of each grant date, including the value determined by a third-party valuation firm. These factors included, among other things, financial performance, capital structure, forecasted operating results and market performance analyses of similar companies in our industry.

Convertible Debt

The fair value of the May Notes and October Notes was measured using a binomial lattice model based on assumptions as to when the May and October Notes would be converted or redeemed at each decision point. The lattice model uses the stock price, maturity date, risk-free rate, estimated stock volatility and estimated credit spread as significant assumptions used to estimate fair value. The May Notes and October Notes are re-measured to fair value at each subsequent reporting date. We will continue to adjust the liability for changes in fair value for the May Notes and October until they mature or are converted to Company stock and present the changes in fair value in the consolidated statement of operations at each reporting period.

Warrants

We classify the Private Placement Warrants as a long-term liability on our consolidated balance sheets as of December 31, 2022 and 2021. The Private Placement Warrants were traded on the NYSE prior to their redemption and recorded at fair value using a Black-Scholes option-pricing model. The Private Placement Warrants are re-measured to fair value at each subsequent reporting date. We will continue to adjust the liability for changes in fair value for the Private Placement Warrants until the warrants are exercised, redeemed or cancelled and present the changes in fair value in the consolidated statement of operations at each reporting period.

We classify the Public Warrants as equity and present within Additional Paid-In Capital on our consolidated balance sheets as of December 31, 2022 and 2021. Although an event such as a qualifying cash tender offer could occur outside of the company’s control that would require net cash settlement, equity classification for the Public Warrants is not precluded per ASC 815-40-25. The Public Warrants were initially recorded using the closing stock price as of the measurement date, with no subsequent measurement.

We classified the May 144A Warrants and October 144A Warrants as long-term liabilities on our consolidated balance sheet as of December 31, 2022. The May 144A and October 144A Warrants were recorded at fair value using the Monte Carlo simulation method. The May 144A Warrants and October 144A Warrants are re-measured to fair value at each subsequent reporting date. We will continue to adjust the liability for changes in fair value for the May 144A Warrants and October 144A Warrants until the warrants are exercised, redeemed or cancelled and present the changes in fair value in the consolidated statement of operations at each reporting period.

Income Taxes

We record income tax expense for the anticipated tax consequences of the reported results of operations using the asset and liability method. Under this method, we recognize deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax basis of asset and liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. We record valuation allowances to reduce its deferred tax assets to the net amount that it believes is more likely than not to be realized. Its assessment considers the realization of deferred tax assets on a jurisdictional basis. We recognize the income tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by taxing authorities, based on the technical merits of the position. The income tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.

Item 7A. Quantitative and Qualitative Disclosures about Market Risk

The Company is a smaller reporting company, as defined by Rule 12b-2 of the Securities Exchange Act of 1934, as amended, and is not required to provide this item.

Report of Independent Registered Public Accounting Firm

To the Stockholders and the Board of Directors of Rockley Photonics Holdings Limited

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Rockley Photonics Holdings Limited (the Company) as of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive loss, stockholders’ equity (deficit) and cash flows for each of the two years in the period ended December 31, 2022, and the related notes

(collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2022 in conformity with U.S. generally accepted accounting principles.

The Company’s Ability to Continue as a Going Concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the consolidated financial statements, the Company has incurred losses from operations since inception and has stated that substantial doubt exists about the Company’s ability to continue as a going concern. Management’s evaluation of the events and conditions and management’s plans regarding these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the

amounts

and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ Ernst & Young LLP

We have served as the Company’s auditor since 2020.

ROCKLEY PHOTONICS HOLDINGS LIMITED

Notes to Consolidated Financial Statements

1.	Description of Business and Significant Accounting Policies

Description of Business

Rockley specializes in the research and development of integrated silicon photonics chipsets. Rockley has developed a versatile, application specific, third-generation silicon photonics platform specifically designed for the optical integration challenges facing numerous mega-trend markets. Rockley has partnered with multiple

tier-1

customers across the markets to deliver complex optical systems required for transformational sensors, communications, and medical product realization.

On August 11, 2021, Rockley Photonics Limited (“Legacy Rockley”) completed a business combination (the “Business Combination”) with SC Health Corporation, a special purpose acquisition company (“SC Health”), with Rockley Photonics Holdings Limited and its subsidiaries surviving the merger. Upon the consummation of the Business Combination, the Company became a publicly traded company listed on the New York Stock Exchange (“NYSE”) under the symbol “RKLY”. For additional information on the Business Combination, please refer to

Note 2

Business Combination

, to these consolidated financial statements. Unless the context otherwise requires, references in these notes to “Rockley”, the “Company”, “we”, “us”, or “our” and any related terms are intended to mean the post-Business Combination consolidated company, Rockley Photonics Holdings Limited, while “Legacy Rockley” and “SC Health” refers to the entities prior to the Business Combination.

Going Concern

The Company has incurred net losses since inception, has an accumulated deficit of $624.9 million as of December 31, 2022 and negative cash flow from operations of $126.2 million for the year ended December 31, 2022 and expects to incur losses from operations for the foreseeable future. As of December 31, 2022, the Company had cash, cash equivalents and investments of approximately $23.0 million. Our financing agreements prior to the bankruptcy proceedings noted below also contained restrictive covenants, including a requirement to maintain a minimum amount of cash on hand, that limited our ability to take certain actions.

As a result, there is substantial doubt about the Company’s ability to continue as a going concern. The consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the normal course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty. Such adjustments could be material.

On March 10, 2023, we filed a voluntary petition for relief under chapter 11 of title 11 of the United States Code in the Bankruptcy Court to implement the “Plan of Reorganization” in order to facilitate the Company’s restructuring. On March 10, 2023, the Bankruptcy Court entered its Order approving the Plan of Reorganization. Rockley’s ordinary shares and public warrants have been delisted from the New York Stock Exchange and Rockley intends to file to deregister as a public company shortly after the filing of this Form

10-K.

Rockley may be unable to successfully implement the Plan of Reorganization and restructuring and could therefore fail to emerge from bankruptcy, in which case it would cease operations as an independent company or otherwise.

Global Pandemic

The

COVID-19

pandemic has reached the three-year mark and our priority continues to be the health and safety of our employees. The overall recovery from the

COVID-19

pandemic has been uneven and has presented many challenges and risks from general economic uncertainty changes in consumer demand, disruption of supply chains and challenges with hiring, labor and supply cost inflation. We continue to provide greater levels of work flexibility to employees and maintain health and safety standards for employees meeting all regulatory requirements.

We continually evaluate the nature and extent of changes to the market and economic conditions related to the

COVID-19

pandemic and assess the potential impact on our business, financial results and overall financial position.

Basis of Presentation and Preparation

The accompanying consolidated financial statements have been prepared by the Company, and reflect all adjustments, consisting only of normal recurring adjustments, that are, in the opinion of management, necessary for the fair presentation of our financial position, results of operations, comprehensive income, cash flows and shareholders’ equity for the periods presented. The consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the U.S. SEC. All intercompany transactions and balances between the various legal entities comprising the Company have been eliminated in consolidation.

We accounted for the Business Combination as a forward recapitalization in accordance with GAAP (the “Forward Recapitalization”). Under this method of accounting, SC Health was treated as the acquired company and Legacy Rockley was deemed to be the accounting acquirer for financial reporting purposes. Accordingly, for accounting purposes, the Forward Recapitalization was treated as the equivalent of Legacy Rockley issuing stock for the net assets of SC Health, accompanied by a recapitalization. The net assets of SC Health are stated at historical cost, with no goodwill or other intangible assets recorded. The consolidated assets, liabilities and results of operations prior to the Forward Recapitalization are those of Legacy Rockley. The consolidated financial statements of the combined company post-Forward Recapitalization represents the combined results of Rockley and SC Health beginning August 11, 2021, the date the Business Combination was consummated. The shares, corresponding capital amounts and earnings per share available for shareholders of Legacy Rockley, prior to the Business Combination, converted into the right to receive 2.4835 shares (the “Exchange Ratio”) of ordinary shares, par value $0.000004 (the “ordinary shares”). The recapitalization of the number of ordinary shares attributable to Legacy Rockley is reflected retroactively as shares reflecting the Exchange Ratio to the earliest period presented and is utilized for calculating earnings per share in all prior periods presented.

The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods. Such estimates include, but are not limited to, revenue recognition, reserves and allowances; valuation of intangibles; product warranties; employee compensation and benefit accruals; stock-based compensation; loss contingencies; income taxes; fair value measurements; and warrant liabilities. Actual results could differ materially from those estimates. Management’s estimates include, as applicable, the anticipated impacts of the

COVID-19

pandemic.

Certain reclassifications have been made to the prior year presentation to conform to the current year presentation. These reclassifications had no impact on consolidated net loss, consolidated shareholder’s equity, earnings per share, or cash flows as previously reported.

Cash and Cash Equivalents

Cash and cash equivalents include short-term, highly liquid investments with an original maturity of three months or less at the time of purchase.

Accounts Receivable

Accounts receivable is recorded at the invoiced amount and do not bear interest. We assess the need for an allowance for doubtful accounts based upon an analysis of past credit history and the current financial condition of its customers, as well as the consideration of expected trends based upon characteristics of the accounts and general economic conditions. Account balances are written off against the allowance after all means of collection have been exhausted and the potential for recovery is considered remote.

Equity Method Investments

Equity method investments are all entities over which we have significant influence but not control or joint control. Under the equity method of accounting, the investments are initially recognized at cost and adjusted thereafter to recognize the Company’s share of the post-acquisition profits or losses of the investee in the consolidated statement of operations. Earnings and losses of equity method investments are based on the most recently available financial statements of the investee. Basis differences between the cost of an equity method investment and the underlying equity in the long-lived assets are amortized over the estimated economic useful life of the underlying long-lived asset. We periodically review our equity method investments for impairment and record a reduction in the carrying value, if and when necessary. To date, no such impairment losses have been recorded.

Available-for-Sale

Investments

The investments in debt securities are classified as

available-for-sale

investments. Debt securities primarily consisted of corporate bonds, commercial paper and U.S. Treasury debt securities. These investments were primarily held in the custody of a major financial institution. A specific identification method is used to determine the cost basis of debt securities sold. These investments were recorded in the consolidated balance sheets at fair value.

Unrealized gains and temporary losses, net of related taxes, are included in accumulated other comprehensive income (loss) (“AOCI”). Upon realization, those amounts are reclassified from AOCI to earnings. The amortization of premiums and discounts on the investments are included in our results of operations. Realized gains and losses are calculated based on the specific identification method.

We classify our investments as current or

non-current

based on the nature of the investment and their availability for use in current operations.

Other-than-Temporary Impairments on Investments

All of our

available-for-sale

investments are subject to periodic impairment review. When the fair value of a debt security is less than its amortized cost, it is deemed impaired, and we assess whether the impairment is other-than-temporary. An impairment is considered other-than-temporary if (i) we have the intent to sell the security, (ii) it is more likely than not that we will be required to sell the security before recovery of the entire amortized cost basis, or (iii) we do not expect to recover the entire amortized cost basis of the security. If impairment is considered other-than-temporary based on condition (i) or (ii) described above, the entire difference between the amortized cost and the fair value of the debt security is recognized in the results of operations. If an impairment is considered other-than-temporary based on condition (iii) described above, the amount representing credit losses (defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis of the debt security) is recognized in earnings, and the amount relating to all other factors is recognized in other comprehensive income (OCI).

Property and Equipment, Net

Property and equipment are recorded at cost and presented net of accumulated depreciation and amortization. Significant additions or improvements extending the useful life of an asset are capitalized, while repairs and maintenance costs are expensed as incurred. Leasehold improvements are amortized on a straight-line basis over the shorter of the term of the lease or the useful life of the assets. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related assets.


Computer equipment		3 years
Lab equipment		3 years
Furnitures and fixtures		4 years
Leasehold improvements		Shorter of the lease term and the useful life

Table of Contents

Impairment of Long-Lived Assets

We evaluate our long-lived assets, such as property and equipment, and

right-of-use

assets for impairment whenever events or changes in circumstances indicate that the carrying value of assets or asset group may not be recoverable. Recoverability of these assets or asset groups is measured by comparing their carrying value to the future net undiscounted cash flows the assets are expected to generate over their remaining economic life. If such assets or asset groups are considered impaired, the impairment to be recognized is measured by the amount by which the carrying value of the assets exceeds their fair value.

The Company tests other intangible assets not subject to amortization for impairment annually and more frequently if events or changes in circumstances between annual tests indicate that it is more likely than not that the asset is impaired.

For the purposes of assessing impairment, assets are grouped at the lowest levels for which there are separately identifiable cash inflows which are largely independent of the cash inflows from other assets or groups of assets. To date, no such impairment losses have been recorded.

Revenue Recognition

We generate our revenue principally from development services, which entails developing the customer-specific designs of photonics chips. Revenue is recognized when control of promised goods and services are transferred to customers in an amount that reflects the expected consideration in exchange for those products and services. This principle is achieved by applying the following five-step approach:

•

Identification of the contract with a customer—

A contract with a customer exists when we enter into an enforceable contract with a customer that defines each party’s rights and obligations regarding the goods or services to be transferred and identifies the payment terms related to these goods or services, the contract has commercial substance, and we determine that collection of substantially all consideration for goods or services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. We consider the terms and conditions of the contracts and customary business practices in identifying contracts under Topic 606 Revenue from Contracts with Customers. Our contracts with a customer generally consist of a development services contract against which statements of work (“SOW”) are issued. Each SOW contains one or more agreed-upon projects. We consider the arrangement to be the development services contract combined with the SOW. While the typical duration of a development services contract is multiple years, we generally expect the duration of agreed-upon projects to be six months or less. Generally, our customers have the right to cancel their contracts at any time.

•

Identification of the performance obligations in the contract

—Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract. To the extent a contract includes multiple promised goods or services, we apply judgment to determine whether promised goods or services are capable of being distinct and distinct in the context of the contract. If these criteria are not met, the promised goods or services are accounted for as a combined performance obligation. The individual components of the development services are generally capable of being distinct but not distinct in the context of the contract unless all the goods and services within a certain agreed-upon project of the contract are completed. Generally, the deliverables associated with each agreed-upon project, when combined, are considered a distinct performance obligation.

•

Determination of the transaction price

—The transaction price is determined based on the consideration to which we are entitled in exchange for transferring goods or services to the customer. Our contracts generally do not contain a significant amount of variable consideration as the price of our services are generally fixed at the inception of the agreed-upon project. The Company excludes sales taxes and other taxes from the measurement of transaction price. None of the contracts contain a significant financing component.

•

Allocation of the transaction price to the performance obligations in the contract

—Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price (“SSP”). The Company prices each agreed-upon project with an SOW at SSP based on the expected cost plus a margin approach.

Table of Contents

•

Recognition of revenue when or as performance obligations are satisfied

—We satisfy performance obligations at a point in time for the development services since the customers do not simultaneously receive and consume the benefits, we do not create or enhance an asset that the customer controls, and we do not have an enforceable right to payment for the performance completed to date. The contracts also contain substantive acceptance terms for each agreed-upon project. Revenue is recognized at the time the related performance obligation is satisfied through the transfer of control of a promised good or service to a customer, which is upon achievement of the agreed-upon project and acceptance by the customer.

Contract balances

—The timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable is recorded when the right to consideration is unconditional. We generally have the right to invoice the customer upon acceptance of the agreed-upon project. The payment terms on invoiced amounts are typically

30-45

days, and such amounts are nonrefundable. In situations where revenue recognition occurs before invoicing, an unbilled receivable is recorded, which represents a contract asset. Deferred revenue is recognized if we have an unconditional right to bill or have collected consideration in advance of the right to recognize revenue. There have been no contract balances recorded to date.

Costs to obtain and fulfill a contract—

Incremental costs incurred to obtain a contract with a customer are required to be capitalized and amortized over the period in which the goods and services to which the asset relates are transferred to the customer. We have not incurred any incremental costs in connection with obtaining the revenue contracts. We recognize an asset from the costs to fulfill a contract only if, the costs relate directly to a contract or an anticipated contract, the costs generate or enhance resources of the Company that will be used in satisfying a performance obligation in the future, and the costs are expected to be recovered. These costs have been insignificant to date.

Foreign Currency Transactions

The Company’s reporting currency is the U.S. dollar and the functional currency of the Company’s foreign subsidiaries is the U.S. dollar. Assets and liabilities that are not denominated in the functional currency are remeasured into the functional currency with any related gain or loss recorded in earnings.

Transaction gains and losses that arise from exchange rate fluctuations on transactions denominated in a currency other than the functional currency are included in realized and unrealized losses/(gains) on foreign currency in the accompanying consolidated statements of operations.

Segment Information

Operating segments are defined as components of an entity for which discrete financial information is available that is regularly reviewed by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources to an individual segment and in assessing performance. The Company’s Chief Executive Officer is the CODM. The CODM reviews financial information presented on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company determined that it has one operating and reportable segment.

Concentration of Risk

Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents,

available-for-sale

investments, accounts receivable and revenue. We maintain cash balances at financial institutions that management believes are high-credit, quality financial institutions, where deposits, at times, exceed the Federal Deposit Insurance Corporation limits.

Table of Contents

Net Loss Per Share

Basic earnings per share is calculated using our weighted-average outstanding ordinary shares. Diluted earnings per share is calculated using our weighted-average outstanding ordinary shares including the dilutive effect of outstanding equity instruments as determined under the treasury stock method. For periods in which we report net losses, diluted net loss per ordinary share attributable to ordinary stockholders is the same as basic net loss per ordinary share attributable to ordinary stockholders, because all potentially dilutive ordinary shares are anti-dilutive.

Stock-Based Compensation

We recognize all stock-based awards to employees and directors as stock-based compensation expense based upon their fair values on the date of grant. Compensation expense is generally recognized as expense on a straight-line basis over the service period based on the vesting requirements. We recognize forfeitures as they occur. We estimate the fair value of stock options granted to employees using the Black-Scholes option pricing model, which requires the input of subjective assumptions, including (i) the fair value of ordinary shares, (ii) the expected stock price volatility, (iii) the expected term of the award, (iv) the risk-free interest rate and (v) expected dividends. The grant-date fair value of restricted stock is calculated based on the fair value of the underlying ordinary shares .

We measure nonemployee awards at their fair value on the adoption date of ASU

No. 2018-07.

Following the adoption of ASU

No. 2018-07

on January 1, 2018, the accounting for nonemployee awards is consistent with the accounting for employee stock-based compensation as described above.

We granted options and restricted stock units which vest on the satisfaction of a service-based condition.

Warrants

We determine the accounting classification of warrants, as either liability or equity classified, by first assessing whether the warrants meet liability classification in accordance with ASC

480-10, Accounting

for Certain Financial Instruments with Characteristics of both Liabilities and Equity, then in accordance with ASC

815-40, Accounting

for Derivative Financial Instruments Indexed to and Potentially Settled in, a Company’s Own Stock. Under ASC 480, warrants are considered liability classified if the warrants are mandatorily redeemable, obligate the Company to settle the warrants or the underlying shares by paying cash or other assets, and warrants that must or may require settlement by issuing variable number of shares. If warrants do not meet the liability classification under ASC

480-10,

the Company assesses the requirements under ASC

815-40,

which states that contracts that require or may require the issuer to settle the contract for cash are liabilities recorded at fair value, irrespective of the likelihood of the transaction occurring that triggers the net cash settlement feature. If the warrants do not require liability classification under ASC

815-40,

in order to conclude equity classification, the company also assesses whether the warrants are indexed to the Company’s ordinary shares and whether the warrants are classified as equity under ASC

815-40

or other U.S. GAAP. After all such assessments, the Company concludes whether the warrants are classified as liability or equity. Liability classified warrants require fair value accounting at issuance and subsequent to initial issuance with all changes in fair value after the issuance date recorded in the statements of operations. Equity classified warrants only require fair value accounting at issuance with no changes recognized subsequent to the issuance date.

Leases

Our lease portfolio is comprised of two major classes: real estate leases, which are the majority of our leased assets, are accounted for as operating leases and a manufacturing equipment lease accounted for as a finance lease on the consolidated balance sheet.

We classify leases as either operating or financing. We determine if an arrangement is a lease at inception by evaluating whether the arrangement conveys the right to use an identified asset and whether we obtain substantially all the economic benefits from and have the ability to direct the use of the asset. Operating lease assets are included under other

non-current

assets and operating lease liabilities under other current and long-term liabilities, respectively in the consolidated balance sheets. We recognize lease expense for operating leases on a straight-line basis over the term of the lease. Finance lease asset is included under property, equipment, and finance lease

right-of-use

assets, net and finance lease liabilities, current portion under other current liabilities in the consolidated balance sheets. Finance ROU assets are amortized on a straight-line basis over their estimated useful lives.

Table of Contents

ROU assets represent the right to use an underlying asset for the lease term and lease liabilities represent the obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at commencement date based on the present value of lease payments over the lease term. As the Company’s leases do not provide an implicit rate, an incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments is used. The operating lease ROU asset includes any lease payments made and excludes lease incentives. Lease terms may include options to extend or terminate the lease when it is reasonably certain that the option will be exercised. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and

non-lease

components, which are generally combined.

We elected, as an accounting policy for leases of real estate, to account for lease and

non-lease

components in a contract as a single lease component. In addition, the recognition requirements are not applied to leases with a term of twelve months or less. Rather, the lease payments for short-term leases are recognized on the consolidated statements of operations on a straight-line basis over the lease term.

Variable payments, such as common area charges, maintenance, insurance and taxes, are primarily based on the amount of space occupied. These payments in the Company’s leases are not dependent on an index or a rate and are excluded from the measurement of the lease liabilities and recognized in the consolidated statements of operations in the period in which the obligation for those payments is incurred. The Company remeasures lease payments when the contingency underlying such variable payments is resolved such that some or all of the remaining payments become fixed.

Cost of Revenue

Our cost of revenue consists of costs related to the Company’s development services which includes cost of materials, cost associated with packaging and assembly, testing and shipping, cost of personnel, including stock-based compensation, and equipment associated with manufacturing support, logistics and quality assurance, overhead and occupancy costs.

Research and Development Expenses (R&D)

Research and development expense consists primarily of personnel costs for engineers and third parties engaged in the design and development of products, software and technologies, including salary, bonus and share-based compensation expense, project material costs, services and depreciation. The Company expenses research and development costs as they are incurred

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist of human capital related expenses for employees involved in general corporate functions, including executive management and administration, accounting, finance, tax, legal, information technology, marketing, and human resources; depreciation expense and rent relating to facilities; travel costs; professional fees; and other general corporate costs. Human capital expenses primarily include salaries, benefits, bonuses and stock-based compensation. As we continue to grow as a company, we expect that our selling, general and administrative costs will increase on an absolute dollar basis.

Income Taxes

Deferred income taxes are provided on a liability method, whereby deferred income tax assets are recognized for deductible temporary differences, operating losses, and tax loss carryforwards, and deferred income tax liabilities are recognized for taxable temporary differences. Deferred income tax balances reflect the effects of temporary differences between the carrying amounts of assets and liabilities and their tax bases and are stated at enacted tax rates expected to be in effect when taxes are actually paid or recovered. Deferred income tax assets are reduced by a valuation allowance when, considering all sources of taxable income, in the opinion of management, it is more likely than not that some portion or all of the deferred income tax assets will not be realized. Deferred income tax assets and liabilities are adjusted for the effects of changes in tax laws and rates on the date of enactment.

Table of Contents

The Company recognizes the income tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained upon examination by taxing authorities, based on the technical merits of the position. The income tax benefits recognized in the financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement.

2.	Business Combination

On August 11, 2021 (the “Closing Date”), Legacy Rockley, SC Health, and Rockley Mergersub Limited, an exempted company incorporated in the Cayman Islands as a direct wholly owned subsidiary of the Company (“Merger Sub”), consummated the business combination contemplated by the Business Combination Agreement and Plan of Merger, dated as of March 19, 2021 (the “Business Combination Agreement”). Immediately upon the consummation of the Business Combination, Legacy Rockley became a wholly owned subsidiary of the Company and Merger Sub merged with and into SC Health, with SC Health surviving the merger and becoming a direct wholly owned subsidiary of the Company. Subsequently, SC Health’s ordinary shares and warrants ceased trading on the NYSE while the Company’s ordinary shares and warrants began trading on the NYSE under the symbols “RKLY” and “RKLY.WS,” respectively.

Pursuant to the Business Combination Agreement, each of the following transactions occurred in the following order: (i) pursuant to a scheme of arrangement approved by the UK courts (the “Scheme”), on August 9, 2021, all of Legacy Rockley’s ordinary shares, including shares issued immediately prior to the Scheme becoming effective as a result of the conversion of then-outstanding convertible loan notes and the exercise of warrants, were transferred by Rockley shareholders in exchange for an equivalent number of shares in the Company; (ii) the holders of options over shares in Legacy Rockley rolled over their options into new options to purchase shares in the Company; (iii) warrants to purchase shares in Legacy Rockley (other than one warrant instrument that by its terms was replicated at the Company) not exercised for shares in Legacy Rockley prior to the effectiveness of the Scheme described above were cancelled, such that immediately following the Scheme, Legacy Rockley became a direct wholly-owned subsidiary of the Company; (iv) the Company subsequently completed a stock-split to prepare its share capital for Merger Sub’s merger into SC Health; (v) certain accredited investors (including entities affiliated with the SC Health Sponsor) purchased an aggregate of 15 million ordinary shares for a purchase price of $10.00 per share, or an aggregate purchase price of $150.0 million; (vi) on August 11, 2021, Merger Sub was merged with and into SC Health, with SC Health surviving the merger and becoming a direct wholly-owned subsidiary of the Company; and (vii) the ordinary shares and warrants in SC Health were exchanged for ordinary shares and warrants in the Company.

Table of Contents

The Business Combination was accounted for as a forward recapitalization, with no goodwill or other intangible assets recorded, in accordance with GAAP. Under this method of accounting, SC Health was treated as the acquired company and Legacy Rockley was deemed to be the accounting acquirer for financial reporting purposes. This determination was primarily based on the existing shareholders of Legacy Rockley obtaining a majority voting power in the Company, and as such, having the power to appoint a majority of the members of the Company’s board of directors (the “Board”); the operations of Legacy Rockley prior to the acquisition comprising the only ongoing operations of the combined entity based on the historical operating activity and employee base; and the senior management of Legacy Rockley comprising the majority of the senior management of the Company. Accordingly, for accounting purposes, the financial statements of the Company represent a continuation of the financial statements of Legacy Rockley with the acquisition being treated as the equivalent of Legacy Rockley issuing stock for the net assets of SC Health, accompanied by a recapitalization.

As a result of the Business Combination, the Company incurred equity issuance costs and other costs considered direct and incremental to the transaction, totaling $45.5 million and consisting of legal, accounting, financial advisory and other professional fees. These amounts are reflected within additional

paid-in

capital in the consolidated balance sheet as of December 31, 2021.

4.	Equity Method Investment

As of December 31, 2022 and 2021, we held an investment in Hengtong Rockley Technology Co., Ltd (“HRT”) and we appointed two of the HRT’s five board members. HRT manufactures and sells optical fiber transceivers based on silicon photonics chipsets. HRT has share capital consisting solely of ordinary shares. We hold 24.9% of HRT’s ordinary shares, and the same proportion of its voting rights. We consider HRT to be a variable interest entity upon which the Company does exercise significant influence. However, considering key factors, such as ownership interest, representation on the board of directors, and participation in policy-making decisions, the Company concluded it does not control the investment. Accordingly, the investment in HRT is accounted for under the equity method. We elected to use a three-month lag to record our share of HRT’s results. See Note 13, Related Party Transactions for details of the Company’s transactions with HRT.

The following table summarizes our investment in HRT for the years ended December 31, 2022 and 2021 (in thousands):

5.	Fair Value Measurements

The accounting guidance for fair value measurements provides a framework for measuring fair value on either a recurring or nonrecurring basis, whereby the inputs used in valuation techniques are assigned a hierarchical level. The following are the three levels of inputs to measure fair value:

Level

Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level

Inputs that reflect quoted prices for identical assets or liabilities in less active markets; quoted prices for similar assets or liabilities in active markets; benchmark yields, reported trades, broker/dealer quotes, inputs other than quoted prices that are observable for the assets or liabilities; or inputs that are derived principally from or corroborated by observable market data by correlation or other means.

Level

Unobservable inputs that reflect our own assumptions incorporated in valuation techniques used to measure fair value. These assumptions are required to be consistent with market participant assumptions that are reasonably available.

We consider an active market to be one in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis, and consider an inactive market to be one in which there are infrequent or few transactions for the asset or liability, the prices are not current, or price quotations vary substantially either over time or among market makers. Where appropriate, our own or the counterparty’s

non-performance

risk is considered in measuring the fair values of liabilities and assets, respectively.

Investments

The following is a summary of our investments at their cost or amortized cost for the years ended December 31, 2022 and 2021 (in thousands):

Private Placement Warrants

The Private Placement Warrants are accounted for as liabilities in accordance with the FASB’s Accounting Standards Codification (“ASC”)

815-40

and are presented within the Warrants Liabilities on the consolidated balance sheet. The warrant liabilities were measured at fair value at inception and are measured on a recurring basis, with changes in fair value presented within change in fair value of warrants liabilities in the consolidated statement of operations.

The Private Placement Warrants are measured at fair value on a recurring basis. The measurement of the warrants as of December 31, 2022 and 2021 was $18 thousand and $3.5 million, respectively. The Company has classified the Private Placement Warrants as a liability due to certain settlement terms and provisions related to certain tender offers and indexation characteristics following the Business Combination and has accounted for them as liability instruments in accordance with ASC 815, adjusting the fair value at the end of each reporting period. Additionally, the Company has determined that the Private Placement Warrants are classified within Level 3 of the fair value hierarchy as the fair value is estimated using the Modified Black Scholes Option Pricing Model.

May Notes

On May 27, 2022, we issued $81.5 million aggregate principal amount of the 2026 Convertible Notes (the “May Notes”) and detachable warrants (the “May 144A Warrants”) to purchase approximately 26.5 million ordinary shares of the Company (see Note 7, Debt and Note 8, Warrants for details). At December 31, 2022, after accounting for conversions and additional issuances described further in Note 7—“Debt”, the outstanding principal balance of the May Notes was $29.3 million .

At December 31, 2022, the fair value of the outstanding principal of the May Notes was $23.5 million which was measured using a lattice model (which is discussed in further detail below) with the following significant inputs:


Fair value per share of ordinary shares, net of 4.0% discount for lack of marketability	$	0.14

Binomial Lattice Model

A lattice model was used to determine the fair value of the May Notes based on assumptions as to when the May Notes would be converted or redeemed at each decision point. Within the lattice model, the following assumptions were made: (i) each holder shall have the option to convert the May Notes to the Company’s ordinary shares at a rate of 324.6753 (the “conversion rate”) per $1,000 principal amount of May Notes prior to the close of the second trading date immediately preceding the maturity date; (ii) at any time prior to the maturity date, the Company may redeem the May Notes in an amount equal to the sum of the redemption price plus the redemption premium; (iii) the holders may surrender the May Notes subject to the optional redemption or tax redemption at any time prior to the close of business on the second trading day immediately preceding the redemption date; and (iv) upon any conversion, other than a conversion “in connection with” a Make-Whole Fundamental Change, Springing Repurchase Offer, a Make-Whole Redemption or a Tax Redemption, the Company will make an interest make-whole payment to the converting holder equal to the sum of the remaining scheduled payments of interest that would have been made on the May Notes to be converted had such May Notes remained outstanding from the conversion date to and including the maturity date. The lattice model uses the stock price, maturity date, risk-free rate, estimated stock volatility, and estimated credit spread. We remeasure the fair value of the debt instrument and record the change as a gain or loss from change in fair value of debt in the statements of operations for each reporting period.

May 144A Warrants issued in connection with the May Notes

In connection with the issuance of the May Notes, we issued detachable May 144A Warrants which were bifurcated from the May Notes and recorded at fair value as a liability. At December 31, 2022, the fair value of the May 144A Warrants was $4.7 million which was measured using the Monte Carlo simulation method. The May 144A Warrants’ ratchet anti-dilution provision creates path-dependent exercise prices of the May 144A Warrants. The Company therefore concluded that the Monte Carlo simulation model is the appropriate method to fair value the May 144A Warrants and the inputs of the valuation model are classified as “Level 3”.

The following key inputs to the Monte Carlo simulation model were used at December 31, 2022:

May Notes

On May 27, 2022, we issued $81.5 million aggregate principal amount of Convertible Senior Secured Notes Due 2026 (the “May Notes”) and warrants (the “May 144A Warrants”) to purchase approximately 26.5 million ordinary shares of the Company. The May Notes bear interest at a rate of 9.5% per annum if paid in cash or, subject to the satisfaction of certain conditions, at a rate of 12.0% per annum payable at a rate of 5.75% per annum in cash and 6.25% per annum through the issuance of additional Notes

(“Payment-in-Kind”

or “PIK”), which will also bear interest. Interest on the May Notes is payable quarterly in arrears on February 15, May 15, August 15 and November 15, commencing on August 15, 2022. The May Notes will mature on May 15, 2026 unless redeemed, repurchased or converted in accordance with their terms prior to such date. The May Notes were issued pursuant to an indenture (the “May Indenture”), which includes customary terms and covenants including certain events of default after which the May Notes may be due and payable immediately.

The Company has also granted the May Note holders an option to purchase up to an additional $81.5 million aggregate principal amount of notes and warrants for a period of 12 months following the date that the registration statement covering the resale of the ordinary shares issuable upon conversion of the May Notes and upon exercise of the May 144A Warrants became effective.

The May Notes are convertible at an initial conversion price equal to $3.08 per ordinary share. Holders of the May Notes have the right to convert all or a portion of their May Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, holders of the May Notes will receive ordinary shares and an interest make-whole for interest that would have accrued from the date of conversion until the maturity date, which interest make-whole shall be paid in cash or in ordinary shares at the Company’s election.

Following certain corporate events that occur prior to the maturity date or notice of redemption issued by the Company (as defined in the May Indenture), the Company will increase the conversion rate for a holder who elects to convert its May Notes in connection with such a corporate event or who elects to convert any May Notes called for redemption during the related redemption period. Additionally, in the event of a fundamental change (as defined in the May Indenture), the holders of the May Notes may require the Company to repurchase all or a portion of their May Notes at a price equal to the aggregate principal amount of any May Notes to be repurchased plus accrued and unpaid interest thereon plus a make-whole premium (as defined in the May Indenture).

The Company may redeem the May Notes in whole, and not in part, at its option, at any time prior to the maturity date, for a cash purchase price equal to the aggregate principal amount of any May Notes to be redeemed plus accrued and unpaid interest plus a make-whole premium as provided in the May Indenture. At any time prior to the maturity date, the Company may also redeem the May Notes in whole, if the last reported sale price of the ordinary shares exceeds 250.0% of the conversion price then in effect for at least 20 trading days (which need not be consecutive), for a cash purchase price equal to the aggregate principal amount of any May Notes to be redeemed plus accrued and unpaid interest thereon. The May Notes are also subject to redemption at the option of the Company in the event of certain changes in tax law or listing status of the Company.

Net proceeds from the offering of the May Notes were $80.7 million after deducting the initial purchasers’ discount of 1.0%. As of December 31, 2022, the Company incurred approximately $11.5 million in transaction costs that was recognized as an expense in the consolidated statements of operations under selling, general and administrative. The Company used approximately $32.3 million of the net proceeds to repay the 2020 Term Facility Loan, which included principal and accrued interest. The Company used or intends to use the remaining net proceeds for operating expenses, working capital, general corporate purposes, and capital expenditures.

The Company allocated the proceeds from the May Notes and May 144A Warrants issued in the financing transaction using a relative fair value method at the issuance date. The issuance-date fair values for the May Notes and May 144A Warrants were measured using the binomial lattice and Monte Carlo simulation model, respectively. The initial amount recognized for the May Notes and May 144A Warrants was established by applying the respective fair values of the May Notes and May 144A Warrants to the amount of the proceeds of $81.5 million on a

pro-rata

basis.

Table of Contents

The Company elected to account for May Notes at fair value as of the May 27, 2022 issuance date. Management believes that the fair value option appropriately reflects the underlying economics of the May Notes. Under the fair value election, changes in fair value will be reported in the consolidated statements of operations, under change in fair value of debt instrument, in each reporting period subsequent to the issuance of the May Notes. For the year ended December 31, 2022, the Company recorded a change in fair value of $26.5 million. See Note 5 – Fair Value Measurements for information on the assumptions that the Company used to measure the fair value of the May Notes.

The Company registered the ordinary shares underlying the May Notes and the May 144A Warrants for sale by the initial purchasers pursuant to a Registration Rights Agreement. The Company’s Registration Statement on Form

S-1

(File

No. 333-266077),

was filed with the SEC on July 11, 2022 and declared effective on July 27, 2022. The Company registered up to 40,316,038 ordinary shares issuable upon conversion of the May 2026 Convertible Notes, which consists of (i) 26,461,038 ordinary shares initially issuable upon conversion of all of the May Notes at a conversion price of $3.08 per ordinary share; and (ii) an additional 13,855,000 ordinary shares that would have become due, assuming that the May Notes were converted on the date they were issued and the interest make-whole payment (as defined in the May Indenture) that would have become due in connection therewith was paid by the Company in ordinary shares on that date. The Company also registered up to 47,251,857 ordinary shares issuable upon the exercise of all the May 144A Warrants, which consists of (i) 26,461,038 ordinary shares initially issuable upon the exercise of all of the May 144A Warrants at an exercise price of $5.00 per ordinary share; and (ii) an additional 20,790,819 ordinary shares that, together with 26,461,038 ordinary shares, would be issuable upon the exercise of all the May 144A Warrants in connection with a ratchet anti-dilution adjustment at an assumed exercise price of $2.80 per ordinary share. See Note 8 - Warrants below.

The May Notes were classified as a current liability in the consolidated balance sheet as of December 31, 2022 due to the filing of the Chapter 11 bankruptcy petition in January 2023, which constituted an event of default under the May Indenture.

In August 2022, $4.8 million of the May Notes with a fair value of $5.5 million were converted for 1.5 million ordinary shares. In connection with the conversion, the noteholder was entitled to $1.7 million of interest make-whole payable in cash. However, an additional $1.7 million of May Notes were issued

in-kind

in accordance with the interest make-whole provision in the May Indenture agreement.

Bridge Notes

On October 3, 2022, the Company issued $12.4 million aggregate original principal amount of senior secured notes due 2022 (the “Bridge Notes”) to (i) raise additional financing of $10.5 million, of which $7.5 million was received by the Company, approximately $1.9 million was applied to pay transaction expenses and the remaining amount of approximately $1.1 million was placed in an escrow account to be released at the direction of the requisite number of noteholders; and (ii) pay certain fees owing to holders of May Notes in an aggregate principal amount of approximately $1.9 million. Dr. Andrew Rickman, the Company’s founder and Chief Executive Officer, invested $0.5 million in Bridge Notes on the same terms as the holders of May Notes, and Dr. Rickman’s participation was separately reviewed and approved by the Company’s Audit Committee and independent members of the Company’s Board of Directors. In connection with the Bridge Note transaction, we also entered into a Forbearance Agreement and obtained a waiver of defaults related to the minimum liquidity covenant in the May Indenture covering the May Notes, and the minimum liquidity covenant was temporarily lowered from $20 million to $5 million.

Table of Contents

On October 25, 2022, the Company paid off the total outstanding principal balance and all accrued interest for the Bridge Notes balance, which resulted in a total cash payment of $12.4 million.

October Notes

On October 25, 2022, we issued $90.6 million in aggregate principal amount of a new series of Convertible Senior Secured Notes Due 2026 (the “October Notes”) with an initial conversion price of $0.6888 and warrants (the “October 144A Warrants”) to purchase approximately 131.6 million ordinary shares of the Company at an exercise price of $1.1182 per share, subject to certain anti-dilution adjustments and repurchased all of the Bridge Notes in an aggregate original principal amount of approximately $12.4 million and a portion of the May Notes in an aggregate original principal amount of $50.0 million. The Company used or intends to use the remaining net proceeds for operating expenses, working capital, general corporate purposes, and capital expenditures. As a result of the conversion price of the October Notes and the initial exercise price of the October 144A Warrants being less than the initial exercise price of the May Warrants, the exercise price of the May 144A Warrants was reset to $2.80 per share and each May 144A Warrant became entitled to an additional 0.7857 shares upon exercise thereof due to the ratchet antidilution provision. The securities were issued in a private placement in reliance on an exemption from the registration requirements of the Securities Act of 1933 (the “Securities Act”) provided by Section 4(a)(2) of the Securities Act.

The October Notes bear interest at a rate of 12.5% per annum if paid in cash or, subject to the satisfaction of certain conditions, at a rate of 15.0% per annum payable at a rate of 5.75% per annum in cash and 9.25% per annum through the issuance of additional Notes

(“Payment-in-Kind”

or “PIK”), which will also bear interest. Interest on the October Notes is payable quarterly in arrears on January 15, April 15, July 15 and October 15, commencing on January 15, 2023. The October Notes will mature on May 15, 2026 unless redeemed, repurchased or converted in accordance with their terms prior to such date. The October Notes were issued pursuant to an indenture (the “October Indenture”), which includes customary terms and covenants including certain events of default after which the October Notes may be due and payable immediately.

The October Notes are convertible at an initial conversion price equal to $0.6888 per ordinary share. Holders of the October Notes have the right to convert all or a portion of their October Notes at any time prior to the close of business on the second scheduled trading day immediately preceding the maturity date. Upon conversion, holders of the October Notes will receive ordinary shares and an interest make-whole for interest that would have accrued from the date of conversion until the maturity date, which interest make-whole shall be paid in cash or in ordinary shares at the Company’s election, provided, however, until the earlier to occur of (x) the third business day prior to December 31, 2022 and (y) the approval by the shareholders of the Company to authorize the issuance of ordinary shares in connection therewith at less than the closing price of such ordinary shares on the trading day immediately preceding the date of the repurchase and subscription agreement, if the Company would not be entitled to otherwise issue such shares in satisfaction of such interest make whole payment because the shares would be valued in accordance with the October Indenture at less than such closing price, the holder who so converted all or a portion of its October Notes will be entitled to either (x) exercise an option under the repurchase and subscription agreement to purchase additional October Notes and Warrants or (y) receive shares valued at such closing price, in each case, in the amount of cash that would otherwise have come due to such holder.

Following certain corporate events that occur prior to the maturity date or notice of redemption issued by the Company (as defined in the October Indenture), the Company will increase the conversion rate for a holder who elects to convert its October Notes in connection with such a corporate event or who elects to convert any October Notes called for redemption during the related redemption period. Additionally, in the event of a fundamental change (as defined in the October Indenture), the holders of the October Notes may require the Company to repurchase all or a portion of their October Notes at a price equal to the aggregate principal amount of any October Notes to be repurchased plus accrued and unpaid interest thereon plus a make-whole premium (as defined in the October Indenture).

in-kind

from the conversion of $4.8 million of May Notes to equity.

As a result of the conversion price of the October Notes and the initial exercise price of the October 144A Warrants being less than the initial exercise price of the May Warrants, the exercise price of the May 144A Warrants was reset to $2.80 per share and each May 144A Warrant became entitled to an additional 0.7857 shares upon exercise thereof due to the ratchet antidilution provision.

October 144A Warrants issued in connection with the October Notes

The Company issued October 144A Warrants in connection with the October Notes with a balance of $26.7 million as of December 31, 2022, classified as a liability.

less than the exercise price then in effect, which automatically decreases the exercise price of the October 144A Warrants upon the occurrence of such event, and increases the number of ordinary shares issuable upon exercise of the October 144A Warrants, such that the aggregate exercise price of all October 144A Warrants remains the same before and after any such dilutive event; provided, that the exercise price may not be less than $0.6262 per ordinary share.

Upon the occurrence of a fundamental transaction (as defined in the October 144A Warrant Agreement), the October 144A Warrants provide each holder a put right. Upon the exercise of a put right by the holder, the Company is obligated to repurchase the October 144A Warrants from the holder for the fair market value (as defined in the October 144A Warrant Agreement) of the remaining exercised portion of the October 144A Warrants repurchased.

The October 144A Warrants also include cashless exercise rights which will go into effect if after the six months of the issue date, there is no effective registration statement registering the ordinary shares underlying the October 144A Warrants. The ordinary shares underlying the October 144A Warrants were registered for sale by the initial purchasers pursuant to the Company’s Registration Statement on Form

S-3,

filed with the SEC on November 1, 2022. The Company registered up to 235,001,542 ordinary shares issuable upon the exercise of all the October 144A Warrants, which consists of (i) 131,600,861 ordinary shares initially issuable upon the exercise of all of the October 144A Warrants at an exercise price of $1.1182 per ordinary share; and (ii) an additional 131,600,861 ordinary shares that, together with 131,600,861 ordinary shares, would be issuable upon the exercise of all the October 144A Warrants in connection with a ratchet anti-dilution adjustment at an assumed exercise price of $0.6262 per ordinary share. The Company also registered up to 208,806,697 ordinary shares issuable upon conversion of the October 2026 Convertible Notes, which consists of (i) 131,600,861 ordinary shares initially issuable upon conversion of all of the October Notes at a conversion price of $0.6888 per ordinary share; and (ii) an additional 77,205,836 ordinary shares that would have become due, assuming that the October Notes were converted on the date they were issued and the interest make-whole payment (as defined in the October Indenture) that would have become due in connection therewith was paid by the Company in ordinary shares on that date. See Note 7 - Debt above.

The October 144A Warrants were accounted for as liabilities in accordance with ASC

815-40,

Derivatives and Hedging-Contracts in Entity’s Own Equity, and are presented within warrant liabilities on our consolidated balance sheet. The liability is remeasured on a recurring basis, with changes in fair value presented in the consolidated statements of operations at each reporting period. The October 144A Warrants are considered to be a Level 3 liability, see Note 5 – Fair Value Measurements for description of the valuation methodology of the October 144A Warrants.

The October 144A Warrants were classified as a current liability and included in the consolidated balance sheet as of December 31, 2022.

Deferred Tax Assets and Liabilities

Deferred income taxes reflect the net effects of (a) temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and (b) operating losses and tax credit carryforwards.

We record income tax expense for the anticipated tax consequences of the reported results of operations using the asset and liability method. Under this method, the Company recognizes deferred tax assets and liabilities for the expected future tax consequences of temporary differences between the financial reporting and tax basis of assets and liabilities, as well as for operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using tax rates that are expected to apply to taxable income for the years in which those tax assets and liabilities are expected to be realized or settled. The Company records valuation allowances to reduce its deferred tax assets to the net amount that it believes is more likely than not to be realized. Its assessment considers the realization of deferred tax assets on a jurisdictional basis.

ASC 740 requires that the tax benefit of net operating losses (“NOLs”), temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is “more likely than not.” Realization of our future tax benefits is dependent on our ability to generate sufficient taxable income within the carryforward period. Management believes that recognition of the deferred tax assets arising from the above-mentioned future tax benefits from operating loss carryforwards is currently not likely to be realized and, accordingly, has provided a valuation allowance has provided a full valuation allowance against its deferred tax assets.

The changes in valuation allowance related to operating activity was an increase in the amount of $79.3 million and $33.8 million during the years ended December 31, 2022 and 2021, respectively.

NOLs and tax credit gross carryforwards as of December 31, 2022 are as follows (in thousands):

Uncertain Tax Positions

The Company recognizes tax benefits from uncertain tax positions only if it believes that it is more likely than not that the tax position will be sustained on examination by the taxing authorities based on the technical merits of the position. As the Company expands, it will face increased complexity in determining the appropriate tax jurisdictions for revenue and expense items. The Company’s policy is to adjust these reserves when facts and circumstances change, such as the closing of a tax audit or refinement of an estimate. To the extent that the final tax outcome of these matters is different than the amounts recorded, such differences will affect the income tax expense in the period in which such determination is made and could have a material impact on its financial condition and operating results. The income tax expense includes the effects of any accruals that the Company believes are appropriate, as well as the related net interest and penalties. As of

Table of Contents

December 31, 2022 and 2021, the Company had total uncertain tax positions of $7.4 million and $3.2 million, which is recorded as a reduction of the deferred tax asset related research and developments. No interest or penalties have been recorded related to the uncertain tax positions. None of the unrecognized tax benefits, if recognized, would affect the effective tax rate. A reconciliation of the beginning and ending balances of unrecognized tax benefits is as follows (in thousands):


	Years Ended December 31,
	2022			2021
Balance at beginning of the year	$	3,217		$	2,236
Increases based on tax positions related to current year		4,458			1,061

Decreases based on tax positions related to prior years		(250	)		(245	)

Balance at end of year	$	7,425		$	3,217

It is not expected that there will be a significant change in uncertain tax position in the next 12 months. We are subject to income tax in the U.K., U.S. federal and various states and three other foreign jurisdictions. During 2021, our U.S. income tax filings were under audit for the tax year ended December 31, 2018. The audit was completed in 2022 with no material findings. The statute of limitations for U.K. and foreign tax jurisdictions other than the U.S. are no longer subject to audit for tax years before December 31, 2020. We are no longer subject to U.S. federal income tax audit for the tax years before the year ended December 31, 2019 and are no longer subject to state income tax audit for tax years before December 31, 2016. The Tax Cuts and Jobs Act requires research and development expenditures to be capitalized and amortized, effective January 1, 2022, which accounts for approximately $4.4 million of the increase in the uncertain tax position for the year ended December 31,

2022.

10.	Shareholders’ Equity (Deficit)

The Company

is authorized to issue

12,443,961,038

ordinary shares with par value of $

0.000004

per share. Each holder of the Company’s ordinary shares is entitled to one vote per share. As of December 31, 2022 and 2021, there were

132,923,224

and

127,860,639

of the Company’s ordinary shares issued and outstanding, respectively. Holders of the Company’s ordinary shares do not have cumulative voting rights. Additionally, the Company has

172,690,795

and

14,074,986

warrants outstanding as of December 31, 2022 and 2021, respectively. See Note 8, Warrants for additional information.

Each holder of the Company’s ordinary shares is entitled to the payment of dividends and other distributions as may be declared by the Board from time to time out of the Company’s assets or funds legally available for dividends or other distributions. The Company has not declared or paid any dividends with respect to its ordinary shares for the periods presented.

If the Company is involved in voluntary or involuntary liquidation, dissolution or winding up of the Company’s affairs, or a similar event, each holder of the Company ordinary shares will participate pro rata in all assets remaining after payment of liabilities, subject to prior distribution rights of the Company preferred shares, if any, then outstanding.

Equity Line of Credit

In October 2021, the Company entered into an equity line of credit arrangement (“ELOC”) with Lincoln Park Capital Fund, LLC, an Illinois limited liability company (“LPCF”). The ELOC is a private placement with registration rights, providing LPCF the ability to purchase up to 7.8 million of the Company’s ordinary shares for $50.0 million over 24 months. Proceeds from the sale of shares will go towards the Company to be used for working capital.

No amounts were drawn against the ELOC during any of the periods presented.

11.	Net Loss per Share

The following is a calculation of basic and diluted net loss per share (in thousands, except for share and per share amounts):


	Years Ended December 31,
	2022			2021
Basic and diluted:
Net loss	$	(224,040	)	$	(168,013	)
Weighted average ordinary shares outstanding		130,348,047			100,917,939

Basic and diluted net loss per share	$	(1.72	)	$	(1.66	)

Basic net loss per share is calculated by dividing net loss for the period by the weighted average number of the ordinary shares outstanding plus outstanding warrants with a 0.01 exercise price during the period.

For the years ended December 31, 2022 and 2021, we excluded the potential effect of outstanding and exercisable options (including performance options), outstanding RSU’s, and warrants in the calculation of the diluted loss per share, as the effect would be anti-dilutive due to losses incurred. As of December 31, 2022, there were approximately 22.0 million outstanding options and RSU’s and 14.1 million of private and public warrants of potentially issuable shares with dilutive effect, May 144A Warrants to purchase approximately 26.5 million ordinary shares and the May Notes described in Note 7—Debt above, as well as October 144A Warrants to purchase approximately 131.7 million ordinary shares and the October Notes described in Note 7—Debt above. As of December 31, 2021, there were approximately 12.6 million potentially issuable shares respectively, with dilutive effect.

12.	Stock-Based Compensation

The Company has established a number of share-based incentive plans for current employees, directors and others, which include Share Appreciation Rights (“SARs”), 2013 Equity Incentive Plan (the “2013 Plan”), 2021 Stock Incentive Plan (the “2021 Plan”), Restricted Stock Units (“RSUs”), 2021 Employee Stock Purchase Plan (the “ESPP”), and Warrants.

Share Appreciation Rights

As of December 31, 2022 and 2021, there were no SARs outstanding. In connection with the Business Combination on August 11, 2021, the liability associated with outstanding SARs was settled with a cash payment of $0.7 million.

2013 Equity Incentive Plan

The holders of Legacy Rockley options under the 2013 Plan continue to hold such options and such options remain subject to the same vesting, exercise and other terms and conditions outlined in the stock option agreements and the 2013 Plan. In connection with the Business Combination, the holders of Legacy Rockley options may exercise their options to purchase a number of ordinary shares equal to the number of Legacy Rockley ordinary shares subject to such Legacy Rockley options multiplied by the Exchange Ratio of 2.4835 (rounded down to the nearest whole share) at an exercise price per share divided by the Exchange Ratio (rounded to the nearest whole cent). The information presented herein is as if the exchange of stock options occurred as of the earliest period presented.

As of December 31, 2022 and 2021, there were no options available for grant. Any new grants will become available for issuance under the 2021 Plan.

Restricted Stock Units

In 2021, the Company granted restricted RSUs to employees and directors under the 2021 Plan. Each award will vest based on continued service which is generally over a four-year period. The grant date fair value of the award will be recognized as stock-based compensation expense over the requisite service period. The fair value of RSUs was estimated on the date of grant based on the fair value of the Company’s ordinary shares.

Employee RSUs activity for the years ended December 31, 2022 and 2021 was as follows:

2021 Employee Stock Purchase Plan

On October 2021, the Company adopted the 2021 Employee Stock Purchase Plan (the “ESPP”), which became effective on December 1, 2021. The purpose of the ESPP is to provide eligible employees with an opportunity to purchase shares of our ordinary shares at a discounted price through payroll deductions with the goal of enhancing employees’ sense of participation in the Company and further align employee interests with those of the Company’s shareholders.

Under the ESPP, eligible employees may purchase shares of Company ordinary shares through payroll deductions of between 1% to 15% of

after-tax

compensation each pay period, with a maximum participation of $25,000 annually. The shares are purchased at the end of each

six-month

offering period at a 15% discount from the closing market price as reported on the New York Stock Exchange on the last trading day of the offering period.

Subject to adjustments provided in the ESPP, the maximum number of ordinary shares available for purchase under the ESPP is 1,526,239 plus an annual increase to be added on the first day of each of the Company’s fiscal years for a period of up to 10 years, beginning with the fiscal year that begins on January 1, 2022, equal to the least of (i) 1% of the outstanding shares on such date, (ii) 7,631,196 shares, or (iii) a lesser amount determined by the Board. As of December 31, 2022 and 2021, 1,526,239 shares were available for issuance under the ESPP.

The initial offering period for the ESPP is one year, commencing on December 1, 2021 and ending on November 30, 2022. As of December 31, 2022, 392,509 ordinary shares have been purchased under the ESPP.

The ESPP was suspended on October 7, 2022. All employee payroll withholdings related to the ESPP were reimbursed subsequent to the suspension of the program.

The assumptions that the Company used in the Black-Scholes option-pricing model to determine the fair value of the purchase rights under the ESPP for the year ended December 31, 2022 and 2021, were as follows:

Stock-based compensation expense

The following table summarizes our stock-based compensation expense for all equity arrangements and is included in the consolidated statements of operations as follows (in thousands):

Total stock-based compensation expense	$	14,333	$	12,013

As of December 31, 2022 and 2021, there was approximately $23.0 million and $40.5 million, respectively of total unrecognized stock based compensation expense related to our equity awards, which is expected to be recognized over a weighted average period of 1.7 years and 1.5 years, respectively

Performance Awards

For the years December 31, 2022 and 2021, we recognized a total expense of $0.2 and $0.3 million respectively in relation to the performance-based options. As of December 31, 2022 and 2021, there were approximately $0 million and $0.9 million of unrecognized stock-based compensation expense related to the performance-based awards. During the years ended December 31, 2022 and 2021, no additional performance-based awards were granted.

Modification of Equity Awards

On June 15, 2022, the Company entered into a separation agreement with our former Chief Financial Officer, which amended his employment agreement and provided for changes in the term of service and compensation under the agreement. The outstanding stock options under the Company’s 2013 Plan held by our former Chief Financial Officer were modified to extend the post-termination exercise period through June 13, 2024. As a result, the Company recorded stock-based compensation expense of $0.2 million related to the incremental fair value of the modified awards.

Valuation of Stock Options

The fair values of options granted during the period were determined using a Black-Scholes option pricing model. The determination of the fair value of stock-based payment awards on the date of grant using an option-pricing model is affected by our stock price as well as assumptions regarding complex and subjective variables. These variables include the expected stock price volatility over the term of the awards, risk-free interest rate and expected dividends.

We estimated expected volatility based on historical data of the price of our ordinary shares over the expected term of the options. The expected term, which represents the period of time that options granted are expected to be outstanding, is estimated based on guidelines provided in U.S. SEC Staff Accounting Bulletin No. 110 and represents the average of the vesting tranches and contractual terms. The risk-free rate assumed in valuing the options is based on the U.S. Treasury rate in effect at the time of grant for the expected term of the option. We do not anticipate paying any cash dividends in the foreseeable future and, therefore, used an expected dividend yield of zero in the option pricing model. Stock-based compensation awards (i.e. options and RSUs) are amortized on over a four-year period with 25% cliff vest at the first year anniversary of the grant and ratably over the next three years. We made an accounting policy election to account for forfeitures in the period they occur.

Warrants

In connection with the Business Combination on August 11, 2021, all outstanding warrants of Legacy Rockley were exercised on a cashless basis and converted into the right to receive 1.8 million ordinary shares of the Company, with a fair value of $18.1 million.

13.	Related Party Transactions

The Company formed HRT, a joint venture with Hengtong Optic-Electric Co., Ltd. in 2017, which was recognized by the Company as an equity method investment. As of and in the year ended December 31, 2022, we made sales to and were owed from the HRT joint venture, $0 and $0, respectively. As of and in the year ended December 31, 2021, we made sales to and were owed from the HRT joint venture, $5.3 million and $3.3 million, respectively. The balance owed by the joint venture was included in accounts receivable in the consolidated balance sheet.

14.

Leases

We have operating leases for office space and a finance lease for manufacturing equipment. These leases have remaining lease terms of 1 to 6 years. Some leases include extension options for up to 5 years. These options are included in the lease term when it is reasonably certain that the option will be exercised.

The weighted average remaining lease term was approximately 3.8 years for operating leases as of December 31, 2022. The weighted average discount rate was 6.4% for operating leases as of December 31, 2022. The weighted average remaining lease term was approximately 2.5 years for finance leases as of December 31, 2022. The weighted average discount rate was 23.22% for finance leases as of December 31, 2022.

15.	Commitments and Contingencies

Legal Contingencies

From time to time, we are a party to various lawsuits, claims and other legal proceedings that arise in the ordinary course of business. We apply accounting for contingencies to determine when and how much to accrue for and disclose related to legal and other contingencies. Accordingly, we disclose contingencies deemed to be reasonably possible and accrue loss contingencies when, in consultation with legal advisors, it is concluded that a loss is probable and reasonably estimable. Although the ultimate aggregate amount of monetary liability or financial impact with respect to these matters is subject to many uncertainties and is therefore not predictable with assurance, management believes that as of December 31, 2022 there are no litigation pending that could have, individually and in the aggregate, a material adverse effect on our financial position, results of operations or cash flows.

Financial Commitments

In the ordinary course of business, we make commitments to third-party suppliers for various research and development activities. As of December 31, 2022 and 2021, we had $8.3 million and $13.6 million, respectively, in contractual obligations for which we have not yet received the services.

16.	Defined Contribution Plan

We have defined contribution plans, under which we contribute based on a percentage of the employees’ elected contributions. We will have no legal or constructive obligation to pay further amounts. Obligations for contributions to defined contribution plans are recognized within selling, general and administrative expenses and research and development in the consolidated statements of operations. Defined contributions were $0.7 million for years ended December 31, 2022 and 2021, respectively.

restructuring to

de-lever

the Company’s consolidated balance sheet by eliminating existing debt and introducing a new capital structure that would provide approximately $35 million of cash for ongoing operations. On January 24, 2023, the Company filed a petition with the Grand Court of the Cayman Islands seeking the appointment of joint restructuring officers to advise the Company and facilitate the restructuring transactions to be effectuated in connection with the Chapter 11 Case.

On March 10, 2023, the Bankruptcy Court approved the adequacy of the Disclosure Statement and confirmed the Plan. The Plan became effective March 14, 2023 (the “Effective Date”).

Effective March 17, 2023, Chad Becker resigned as Chief Financial Officer of the Company. Mr. Becker’s resignation was not in connection with any known disagreement with the Company on any matter. Richard Meier, our Chief Executive Officer, assumed the duties of the Company’s principal accounting officer and principal financial officer upon the effectiveness of Mr. Becker’s resignation.

On December 9, 2022, the Company received a letter from the New York Stock Exchange (“NYSE”) notifying it that the Company is not in compliance with the continued listing requirement in Section 802.01B of the NYSE’s Listed Company Manual because the Company’s market capitalization fell below $50 million over a 30 trading day period and its stockholders’ equity is less than $50 million. On February 21, 2023, as a result of the Chapter 11 Cases in accordance with Section 802.01D of the NYSE Listed Company Manual, the Company’s ordinary shares and warrants were delisted from the NYSE.

On February 21, 2023, the Company executed a restructuring plan to reduce costs and redirect resources to our highest priority activities, which included a reduction in our global workforce by approximately 27%, which resulted in a restructuring charge of $1.9 million consisting of employee severance-related costs.

Effective May 10, 2023, Richard Meier resigned as Chief Executive Officer of the Company. Mr. Meier was also the Company’s principal accounting officer and principal financial officer. Mr. Meier’s resignation was not in connection with any known disagreement with the Company on any matter. Dr. Andrew Rickman, our Executive Chairman of the Board of Directors, assumed the duties of the Chief Executive Officer upon Mr. Meier’s resignation.

Item 9. Changes In and Disagreements with Accountants on Accounting and Financial Disclosure

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

We maintain a system of disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) designed to ensure that the information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission, and is accumulated and communicated to our management, including our Chief Executive Officer (our principal executive officer) and Chief Financial Officer (our principal financial officer and principal accounting officer), as appropriate, to allow timely decisions regarding required disclosure.

Our management, with the participation of our Chief Executive Officer and our Chief Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures under the Exchange Act as of and for the year ended December 31, 2022. Based on such evaluation, our Chief Executive Officer and our Chief Financial Officer have concluded that our disclosure controls and internal control over financial reporting were effective at the reasonable level.

Management’s Report on Internal Controls Over Financial Reporting

This Annual Report on Form 10-K does not include a report of management’s assessment regarding internal control over financial reporting due to a transition period established by rules of the Securities and Exchange Commission for newly public companies.

No Attestation Report of Registered Public Accounting Firm

This Annual Report on Form 10-K does not contain an attestation report of our registered public accounting firm regarding internal control over financial reporting since the Company, as an “emerging growth company,” is not required to provide such report pursuant to Section 404 until we are no longer an ‘emerging growth company” as defined by the JOBS Act.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the year ended December 31, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Inherent Limitations on Effectiveness of Controls

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, in designing and evaluating the disclosure controls and procedures, management recognizes that any system of internal control over financial reporting, including Rockley’s, no matter how well designed and operated, can only provide reasonable, not absolute assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business, but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.

Prior to the bankruptcy proceedings, our Amended and Restated Memorandum and Articles of Association (the “Articles”) provided that our Board shall consist of not less than one and no more than nine directors. The authorized number of directors may be changed by the shareholders of the Company by a resolution passed in a general meeting. Vacancies on our Board can be filled by resolution of our Board. Our Board was divided into three classes, each serving staggered, three-year terms:

•

Our Class I directors were Brian Blaser and Pamela Puryear, and their terms would have expired at the 2025 Annual Meeting of shareholders;

•

Our Class II directors were Nicolaus Henke, Karim Karti and Michele Klein and their terms were to expire at the 2023 Annual Meeting of shareholders; and

•

Our Class III directors were Andrew Rickman, William Huyett and Caroline Brown, and their terms were to expire at the 2024 Annual Meeting of shareholders.

As a result of the bankruptcy proceedings, the terms of each member of our Board expired on March 14, 2023 (the “Effective Date”).

Director Independence

Prior to the Effective Date, our Board determined that six out of eight directors on our Board qualified as independent directors, as defined under the listing rules of the NYSE: Brian Blaser, Caroline Brown, Nicolaus Henke, William Huyett, Michele Klein and Pamela Puryear. There were no family relationships among any of our directors or executive officers.

Compensation Committee Interlocks and Insider Participation

The members of our Compensation Committee during 2022 were Pamela Puryear, William Huyett and Michele Klein, none of whom has ever been an executive officer or employee of ours. None of our executive officers currently serve, or have served during the last completed fiscal year, on the Compensation Committee or Board of any other entity that had one or more executive officers serving as a member of our Board or Compensation Committee.

Board Meetings

Our Board held fifteen meetings during 2022. Each director attended at least 75% of the aggregate meetings held by our Board and the committees on which such director served, during the time such director was a director. We do not have a policy that requires the attendance of directors at the Annual Meeting.

Meeting of Non-Management and Independent Directors and Communications with Directors

The independent directors met in an executive session in connection with each regularly scheduled board meeting, during which the independent directors had the opportunity to discuss, among other matters, management performance. The purpose of these executive sessions was to promote open and candid discussion among the non-management directors.

Board Committees

Prior to the bankruptcy proceedings, we had established an Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee, each of which operated under a charter approved by our Board. We believe that the composition of these committees met the criteria for independence under, and the functioning of these committees complied with the applicable requirements of the Sarbanes-Oxley Act, and the applicable rules and regulations of the SEC and the NYSE. Each committee had the composition and responsibilities described below.

Audit Committee

Members:

Brian Blaser (Chair)

William Huyett

•

reviewing and evaluating on an annual basis the performance of the Audit Committee and the Audit Committee Charter.

Our Board determined that each of the members of our Audit Committee satisfied the independence requirements of the NYSE and Rule 10A-3 under the Exchange Act. Each member of our Audit Committee was able to read and understand fundamental financial statements in accordance with NYSE audit committee requirements. In arriving at this determination, our Board examined each Audit Committee member’s scope of experience and the nature of their prior and current employment.

Our Board determined that Dr. Brown qualifies as an audit committee financial expert within the meaning of SEC regulations and meets the financial sophistication requirements of the NYSE listing rules. In making this determination, our Board considered Dr. Brown’s formal education and previous experience in financial roles. Both our independent registered public accounting firm and management periodically met privately with our Audit Committee.

Compensation Committee

Members:

Pamela Puryear (Chair)

William Huyett

Michele Klein

Number of meetings in 2022: 8

The functions of this committee included, among other things:

This includes discussion of any significant trends or regulatory events or risks.

Our Board determined that each of the members of the Compensation Committee was a non-employee director, as defined in Rule 16b-3 promulgated under the Exchange Act, and satisfied the independence requirements of the NYSE.

The Compensation Committee had the authority, in its sole discretion, to select, retain and obtain the advice of a compensation consultant and outside legal counsel as necessary to assist with the execution of its duties and responsibilities. In 2022, the Compensation Committee retained Semler Brossy Consulting Group, LLC (“Semler Brossy”) to provide advice and counsel. Semler Brossy provided compensation advice to the Committee on our Chief Executive Officer, Chief Financial Officer and the next three highest-paid executives.

100

The Compensation Committee assessed the independence of Semler Brossy pursuant to SEC and NYSE rules and determined that no conflict of interest existed that would prevent Semler Brossy from independently representing the Committee. In making this assessment, the Committee considered each of the factors set forth by the SEC and the NYSE with respect to the Semler Brossy’s independence, including that Semler Brossy provided no services for the Company other than pursuant to its engagement by the Committee. The Committee also determined there were no other factors the Committee should consider in connection with the assessment or that were otherwise relevant to the Committee’s engagement of Semler Brossy.

Nominating and Corporate Governance Committee

Members:

Michele Klein (Chair)

Nicolaus Henke

Pamela Puryear

Number of meetings in 2022: 5

The functions of this committee included, among other things:

•

evaluating the performance of our Board, committees of our Board, and individual directors and determining whether continued service on our Board is appropriate;

•

evaluating nominations by shareholders of candidates for election to our Board;

reviewing periodically the Nominating and Corporate Governance Committee Charter, structure, and membership requirements and recommending any proposed changes to our Board, including undertaking an annual review of its own performance.

Our Board determined that each of the members of our Nominating and Corporate Governance Committee satisfied the independence requirements of the NYSE.

Corporate Governance Guidelines

Our Board adopted written corporate governance guidelines (the “Corporate Governance Guidelines”) to ensure that the Board had the necessary authority and practices in place to review and evaluate our business operations as needed and to make decisions independent of our management. The guidelines were also intended to align the interests of directors and management with those of our shareholders. The Corporate Governance Guidelines set forth the practices the Board followed with respect to board composition and selection, board meetings and involvement of senior management, Chief Executive Officer performance evaluations and succession planning, and board committees and compensation. The Nominating and Corporate Governance Committee assisted our Board in implementing and adhering to the Corporate Governance Guidelines. The Corporate Governance Guidelines had been reviewed at least annually by the Nominating and Corporate Governance Committee, and changes were recommended to our Board as warranted.

101

Role in Risk Oversight

One of the key functions of our Board was informed oversight of our risk management process. Our Board did not have a standing risk management committee, but rather administered this oversight function directly through our Board as a whole, as well as through various standing committees of our Board that addressed risks inherent in their respective areas of oversight. In particular, our Board was responsible for monitoring and assessing strategic risk exposure and our Audit Committee had the responsibility to consider and discuss our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management was undertaken. The Audit Committee also monitored compliance with legal and regulatory requirements. Our Compensation Committee assessed and monitored whether our compensation plans, policies, and programs comply with applicable legal and regulatory requirements. The Nominating and Corporate Governance Committee also periodically evaluated our risk management process in light of the nature of the material risks we faced and the adequacy of our governance policies and procedures designed to address risk.

Code of Business Conduct and Ethics

We believe that our corporate governance initiatives complied with the Sarbanes-Oxley Act and the rules and regulations of the SEC adopted thereunder. In addition, we believe our corporate governance initiatives complied with the rules of the NYSE.

Our Board adopted a Code of Business Conduct and Ethics that applied to each of our directors, officers and employees. The code addressed various topics, including:

•

compliance with laws, rules and regulations;

•

confidentiality;

•

conflicts of interest;

•

corporate opportunities;

•

competition and fair dealing;

•

payments or gifts from others;

•

health and safety;

•

insider trading;

•

protection and proper use of company assets; and

•

record keeping.

Our Board also adopted a Code of Ethics for Senior Financial Officers applicable to our Chief Executive Officer and Chief Financial Officer as well as other key management employees. The Code of Business Conduct and Ethics and the Code of Ethics for Senior Financial Officers are each posted on our website investors.rockleyphotonics.com. The Code of Business Conduct and Ethics and the Code of Ethics for Senior Financial Officers could only be amended by the approval of a majority of our Board. Any waiver to the Code of Business Conduct and Ethics for an executive officer or director or any waiver of the Code of Ethics for Senior Financial Officers could only be granted by our Board or our Nominating and Corporate Governance Committee and had to be timely disclosed as required by applicable law. We implemented a whistleblower policy that established formal protocols for receiving and handling complaints from employees through an independent third-party reporting company.

To date, there have been no waivers under our Code of Business Conduct and Ethics or Code of Ethics for Senior Financial Officers.

Anti-Hedging Policy

Under our insider trading policy, our directors, officers, employees, consultants and contractors were prohibited from engaging in short sales of our securities, purchases of our securities on margin, hedging or monetization transactions through the use of financial instruments, and options and derivatives trading on any of the stock exchanges or futures exchanges, without prior written pre-clearance from our General Counsel.

Availability of Corporate Governance Documents

Our Corporate Governance Guidelines, Code of Business Conduct and Ethics, Code of Ethics for Senior Financial Officers, charters for each of the Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee and other corporate governance documents, are posted on the investor relations section of our website at www.rockleyphotonics.com under the heading “Governance — Governance Documents.”

For grants made prior to our initial public offering, the fair value of the stock awards was determined using a third-party valuation firm.

The following table sets forth the aggregate number of shares of common stock underlying option awards and restricted stock unit awards outstanding as of December 31, 2022:

Other Compensation Arrangements

Employee directors did not receive any compensation for service as a member of our Board. We reimbursed our non-employee directors for their reasonable out-of-pocket costs and travel expenses in connection with their attendance at board and committee meetings. We have also, from time to time, granted stock options or restricted stock units (“RSUs”) to our non-employee directors as compensation under our equity incentive plans.

We adopted a non-employee director compensation policy that includes the following cash compensation for non-employee directors, which was based on a review of director compensation at comparable companies in our industry, consisting of a $45,000 annual retainer, an additional $23,000 annual retainer for the Lead Independent Director and the following additional annual retainers for committee service:


Committee	Chair		Member
Compensation	$	15,000	$	7,500
Nominating and Corporate Governance		10,000		5,000
Audit		20,000		10,000

103

The non-employee director compensation policy also provided for the annual grant of RSUs under our 2021 Stock Incentive Plan (the “2021 Plan”) following the conclusion of each regular annual meeting of our shareholders, commencing with the 2022 Annual Meeting, to each non-employee director who will continue serving as a member of the Board. The annual RSU award was with respect to a number of ordinary shares having an aggregate fair market value equal to $162,000 calculated on the date of grant.

Each annual RSU award became fully vested, subject to continued service as a director, on the earliest of the twelve (12) month anniversary of the date of grant, the next annual meeting of shareholders following the date of grant, or the consummation of a change in control as defined in the 2021 Plan.

Our board of directors adopted a Code of Business Conduct and Ethics that applies to all of our employees, officers, and directors, including our Chief Executive Officer, Chief Financial Officer and other executive and senior financial officers. The full text of our code of conduct is posted on the investor relations section on our website, which is located at https://investors.rockleyphotonics.com. We intend to satisfy the disclosure requirement under Item 5.05 of Form 8-K regarding amendment to, or waiver from, a provision of our Code of Business Conduct and Ethics by posting such information in the investor relations section of our website.

Compensation Table

We review compensation annually for all employees, including our named executive officers. In setting our named executive officers’ base salaries and bonuses and granting equity incentive awards, we seek to align pay for performance and consider, among other factors, compensation for comparable positions in the market, the historical compensation levels of our named executive officers, individual performance as compared to our expectations and objectives, our desire to motivate our named executive officers to achieve short- and long-term results that are in the best interests of our shareholders, and a long-term commitment to our company.

Base Salaries

In 2022, each of the named executive officers of Rockley received an annual base salary to compensate them for services rendered to Rockley. The base salary payable to each named executive officer was intended to provide a fixed component of compensation reflecting such executive’s skill set, experience, role, and responsibilities.

Annual Cash Bonuses

In 2022, Mr. Meier was eligible to earn a bonus of up $400,000 and Mr. Becker was eligible to earn a bonus targeted at 60% of his base salary. Each named executive officer was eligible to earn his bonus based on the attainment of company and individual performance metrics, as determined by the Board, in its discretion. The actual annual cash bonuses awarded to each named executive officer for 2022 performance are set forth above in the Summary Compensation Table in the column titled “Nonequity Incentive Plan Compensation”. Dr. Rickman and Messrs. Karanth and Nagra did not receive any bonus in 2022.

Non-Equity and Incentive Awards Granted in 2022 to Our Named Executive Officers

Pursuant to Mr. Meier employment agreement, on October 21, 2022, Mr. Meier was granted restricted stock units with respect to 1,891,521 ordinary shares and a stock option to purchase 1,891,521 ordinary shares at a price equal to the fair market value of such shares on the grant date, with both equity awards vesting over four years, with 25% of each award vesting on the first anniversary of that award’s date of grant and the remaining portion vesting in quarterly installments over the remaining three years, subject to Mr. Meier’s continued service. In addition, in the event Mr. Meier’s employment is terminated by the Company without cause or by Mr. Meier for good reason on or within 12 months following a change in control of the Company, subject to Mr. Meier’s executing a release, these equity grants will vest in full.

Retirement Plans

In 2022, Dr. Rickman participated in the Rockley U.K. pension (“U.K. Pension”) and our other executives participated in the ADP TotalSource Retirement Savings Plan, a multiple employer defined contribution plan in which Rockley participates (“401(k) Plan”). The U.K. Pension and the 401(k) Plan are designed to take advantage of certain provisions of Her Majesty’s Revenue and Customs and the Internal Revenue Code, respectively, which allow eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis to the U.K. Pension or the 401(k) Plan, as applicable. In 2022, contributions made by participants in the U.K. Pension and the 401(k) Plan were matched up to a specified percentage of the employee contributions on behalf of the named executive officers. These matching contributions are fully vested as of the date on which the contribution is made.

Employment Agreements with Our Named Executive Officers

Below are descriptions of the material terms of the offer letter agreements with our named executive officers. These agreements generally provide for at-will employment and set forth the named executive officer’s initial base salary and eligibility for employee benefits.

Employment Agreement with Richard Meier

We entered into an amended employment agreement with Mr. Meier in 2022 pursuant to which he will receive a base salary of $500,000 with a target bonus opportunity equal to 80% of his annual base salary, including a $400,000 bonus opportunity for 2022. Under his employment agreement, Mr. Meier also received an initial equity grant consisting of RSUs and stock options. In the event Mr. Meier’s employment is terminated by the Company without cause or by Mr. Meier for good reason, subject to his execution of a release, Mr. Meier will be eligible to receive (i) a lump sum equal to his annual salary and target bonus, plus any earned but unpaid annual bonus for the prior completed calendar year, and (ii) 12 months of Company paid COBRA premiums. If such a termination occurs on or within 12 months following a change in control of the Company, subject to Mr. Meier’s executing a release, Mr. Meier’s initial equity grants will vest in full.

Employment Agreement with Andrew Rickman

We entered into an amended employment agreement with Dr. Rickman in 2021 in connection with the Business Combination, pursuant to which Dr. Rickman served as the chief executive officer of Rockley. The terms of Dr. Rickman’s employment did not change in connection with his becoming executive chair and stepping down as the Company’s CEO in December of 2022. Effective May 10, 2023, Dr. Rickman succeeded Mr. Meier as the Company’s CEO.

Under the amended employment agreement, among other terms, Dr. Rickman is entitled to receive an annual base salary of $500,000 and is eligible to receive an annual performance bonus targeted at 100% of Dr. Rickman’s annual base salary. The actual amount of any such bonus will be determined by reference to the attainment of applicable Rockley and/or individual performance objectives, as determined by the Board or the Compensation Committee.

107

Dr. Rickman will also be eligible to participate in the customary health, welfare, and fringe benefit plans we provided to our employees.

In addition, we entered into a side letter pursuant to which Dr. Rickman became eligible to receive equity awards with a fair value of $5.0 million in connection with the Business Combination, to be split between stock options and RSUs, which awards were granted in 2021 and are described in “Equity and Incentive Awards Granted in 2021 to Our Named Executive Officers” above and the “Outstanding Equity Awards at Fiscal Year-End Table”, below.

Under his amended employment agreement, we must provide Dr. Rickman at least 12 months’ notice, or pay in lieu of notice, prior to any termination of his employment unless that termination is for “cause” (as defined under his amended employment agreement). Dr. Rickman must provide us with at least 12 months’ notice prior to his resignation, unless we reasonably determine that such resignation is for “good reason” (as defined in his amended employment agreement).

If Dr. Rickman’s employment is terminated by us without “cause,” or by Dr. Rickman for “good reason,” subject to his execution and non-revocation of a release of claims and continued compliance with his confidentiality and non-solicitation requirements, then, in addition to any accrued amounts, Dr. Rickman will be entitled to receive the following severance payments and benefits: (i) an amount equal to the sum of (a) his annual base salary then in effect and (b) 100% of his target annual bonus amount, payable in equal instalments over one year and reduced by any basic salary paid in lieu of notice; and (ii) continuation of all benefits for a period of 12 months.

The amended employment agreement contains non-competition and non-solicitation and confidentiality provisions which, among other restrictions, and except in the case of an involuntary termination, restrict Dr. Rickman’s ability to be engaged or employed by, undertake duties for or be otherwise interested in our competitors, customers or suppliers, for a period of 12 months following his termination (reduced by any portion of Dr. Rickman’s pre-termination notice period during which time he is not providing services, or “garden leave”).

Employment Agreement with Chad Becker

In connection with Mr. Becker’s appointment as our interim chief financial officer, we entered into an amended employment agreement pursuant to which Mr. Becker would receive a base salary of $370,000 and was eligible for annual performance bonus targeted at 60% of Mr. Becker’s then-current annual base salary.

Employment Agreement with Mahesh Karanth

We entered into an amended employment agreement with Mr. Karanth, pursuant to which Mr. Karanth would serve as the chief financial officer of Rockley and would report directly to our chief executive officer. Under the amended employment agreement, Mr. Karanth received a base salary of $450,000 and was eligible for an annual performance bonus targeted at 60% of Mr. Karanth’s then-current annual base salary. Pursuant to his amended employment agreement, Mr. Karanth was also eligible to participate in the customary health, welfare, and fringe benefit plans we provide to our employees.

In connection with Mr. Karanth’s resignation effective June 13, 2022, Mr. Karanth also received the severance contemplated under his employment agreement, namely, in exchange for his execution and non-revocation of a general release of claims in our favor and continued compliance with customary confidentiality and non-solicitation requirements, Mr. Karanth received, in addition to any accrued amounts, (i) an amount equal to the sum of (a) 6 months of his annual base salary then in effect and (b) 50% of his target annual bonus amount, payable in equal installments over six months; and (ii) payment of premiums for continued healthcare coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 (“COBRA”) for up to 6 months after the termination date.

Employment Agreement with Amit Nagra

We entered into an amended employment agreement with Mr. Nagra pursuant to which Mr. Nagra would serve as the chief operating officer of Rockley and would report directly to our chief executive officer. On January 19, 2022, the Compensation Committee approved an amendment (the “First Amendment”) to Mr. Nagra’s employment agreement, pursuant to which Mr. Nagra’s employment would be terminated on or around March 31, 2022 in connection with the intended monetization of the Company’s ultra-high-speed fiber optic communication solutions (as discussed below and previously in our December 22, 2021 press release), which date could be extended upon mutual agreement. Under the First Amendment, Dr. Nagra was to receive an annual base salary of $450,000 and would be eligible to receive an annual performance bonus targeted at 60% of Dr. Nagra’s then-current annual base salary. Pursuant to his Employment Agreement, Dr. Nagra was also eligible to participate in the customary health, welfare, and fringe benefit plans, provided by us to our employees.

Mr. Nagra’s employment was ultimately terminated on April 15, 2022. In connection with Mr. Nagra’s termination, Mr. Nagra received the severance contemplated under his employment agreement, as amended, namely, in exchange for his execution and non-revocation of a general release of claims in our favor and continued compliance with customary confidentiality and non-solicitation requirements, Mr. Nagra received, in addition to any accrued amounts, (i) an amount equal to the sum of (a) 6 months of his annual base salary then in effect and (b) 50% of his target annual bonus amount, payable in equal installments over six months; and (ii) payment of premiums for continued healthcare coverage under the COBRA for up to 6 months after the termination date.

Equity Compensation Plan Information

For equity compensation plan information, see Note 12 to the Consolidated Notes to Financial Statements.

Item 12. Security Ownership of Certain Beneficial Owners and Management

The following table sets forth certain information as of March 10, 2023, the most recent practicable date for which such information was available, as to our ordinary shares beneficially owned by: (1) each person who is known by us to own beneficially more than 5% of our ordinary shares, (2) each of our named executive officers and directors, and (3) all of our current directors and executive officers as a group.

Beneficial ownership is determined according to the rules of the SEC, which generally provide that a person has beneficial ownership of a security if he, she or it possesses sole or shared voting or investment power over that security, including options and warrants that are currently exercisable or exercisable within 60 days.

109

The beneficial ownership percentages set forth in the table below are based on approximately 132,747,605 ordinary shares outstanding as of March 10, 2023.

In computing the number of ordinary shares beneficially owned by a person and the percentage ownership of that person, we deemed outstanding ordinary shares subject to options held by that person that are currently exercisable, or RSUs that vest, in each case, within 60 days of March 10, 2023. We did not deem these shares outstanding, however, for the purpose of computing the percentage ownership of any other person.

Except as otherwise set forth in footnotes to the table below, the address of each of the persons listed below is 3rd Floor 1 Ashley Road, Altrincham, Cheshire, WA14 2DT, United Kingdom.

Dr. Rickman has pledged up to 6.0 million of his Rockley ordinary shares to facilitate the Sponsor’s financing of its PIPE subscription commitment, which, if forfeited in their entirety, would reduce his estimated beneficial ownership by approximately 4%. The lender may have dispositive power over such pledged shares but would not have voting power unless and until such shares are forfeited to the lender. In addition, Sponsor-affiliated entities have agreed to transfer shares held by such entities to Dr. Rickman in exchange for Dr. Rickman’s making available up to 6.0 million of his Rockley ordinary shares to facilitate the Sponsor’s financing of its PIPE subscription commitment, with the number of shares to be transferred to be based on the price performance of Rockley ordinary shares.

Item 13. Certain Relationships and Related Transactions, and Director Independence

In addition to the compensation arrangements of our directors and named executive officers discussed elsewhere in this Annual Report, the following includes a summary of transactions since January 1, 2022 to which we have been or will be a party, and in which the amount involved exceeded or will exceed $120,000 and in which any of our directors, executive officers, beneficial holders of more than 5% of our capital stock, or entities affiliated with, or immediate family members of, any of the foregoing, had or will have a direct or indirect material interest.

Consultancy Agreements

Rockley engages two affiliate entities of certain of Rockley’s directors for consulting and administrative services, Rockley Ventures Limited and Rockley Management (HK) Limited. For the years ended December 31, 2022 and 2021, Rockley incurred $0.4 million and $0.8 million in fees for these services, respectively. On March 14, 2021, Rockley Photonics, Inc., a subsidiary of Rockley, entered into a consulting agreement with HealthKapital LLC, a California limited liability company wholly owned by Karim Karti, a former director of Rockley. Pursuant to the terms of the consulting agreement, Mr. Karti is entitled to cash compensation at the rate of $600 per hour, estimated at up to 20 hours per week, and fully vested 4,000 RSUs for every 30 days of service during the consultation period, up to a maximum of 24,000 RSUs, subject to the terms and conditions of the consulting agreement.

Intra Group Loans

On January 24, 2022, Rockley (as lender) entered into two separate Intra Group Loan Agreements with RPL (as borrower): (i) one for an amount of $110,000,000; and (ii) one for an amount of $35,000,000 (the “RPL Loans”). The purpose of the RPL Loans is to: (i) cover working capital requirements; and (ii) provide for long term cash investment funds. The interest is the Bank of England base rate from time to time. The amount of the loans will be repayable by RPL on September 1, 2022 or such later date agreed between the parties.

On February 24, 2022, Rockley entered into an Intra Group Loan Agreement with Rockley Photonics Oy as borrower, for an amount of €928,794 (the “Finland Loan”). The Finland Loan will be drawn down in full on or before February 28, 2023 and be repayable immediately by the borrower to Rockley following the final claim submission to a grant funded project with Business Finland (the Finnish funding agency for innovation) scheduled for June 30, 2023.

Indemnification Agreements

We have entered into separate indemnification agreements with our directors and executive officers, in addition to the indemnification provided for in our Articles. These agreements, among other things, require us to indemnify our directors and executive officers for certain expenses, including attorneys’ fees, judgments, fines, and settlement amounts incurred by a director or executive officer in any action or proceeding arising out of their services as one of our directors or executive officers or as a director or executive officer of any other company or enterprise to which the person provides services at our request. We believe that these provisions in our Articles and indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

Policies and Procedures for Transactions with Related Persons

We adopted a written Related Person Transactions Policy that sets forth our policies and procedures regarding the identification, review, consideration, and oversight of “related person transactions.” For purposes of our policy only, a “related person transaction” is a transaction, arrangement, or relationship (or any series of similar transactions, arrangements or relationships, including any indebtedness or guarantee of indebtedness) in which we or any of our subsidiaries are participants, in which any “related person” has a material interest.

Transactions involving compensation for services provided to us as an employee, consultant, or director are not considered related person transactions under this policy. A related person is any executive officer, director, nominee to become a director, or a holder of more than 5% of any class of our voting securities (including our ordinary shares), including any of their immediate family members and affiliates, including entities owned or controlled by such persons.

Under the policy, the related person in question or, in the case of transactions with a holder of more than 5% of any class of our voting securities, an executive officer with knowledge of the proposed transaction, must present information regarding the proposed related person transaction to our Audit Committee (or, where review by our Audit Committee would be inappropriate, to another independent body of our Board) for review. To identify related person transactions in advance, we rely on information supplied by our executive officers, directors, and certain significant shareholders. In considering related person transactions, our Audit Committee takes into account the relevant available facts and circumstances, which may include, but are not limited to:

•

the risks, costs, and benefits to us;

•

the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated;

•

the terms of the transaction;

•

AUDIT COMMITTEE REPORT

The Audit Committee operates under a written charter adopted by the Board. A link to the Audit Committee charter is available on our website at www.rockleyphotonics.com.

In performing its functions, the Audit Committee acts in an oversight capacity and necessarily relies on the work and assurances of the Company’s management, which has the primary responsibility for financial statements and reports, and of the independent registered public accounting firm, who, in their report, express an opinion on the conformity of the Company’s annual financial statements with accounting principles generally accepted in the United States. It is not the duty of the Audit Committee to plan or conduct audits, to determine that the Company’s financial statements are complete and accurate and are in accordance with generally accepted accounting principles, or to assess or determine the effectiveness of the Company’s internal control over financial reporting.

Within this framework, the Audit Committee has reviewed and discussed with management the Company’s audited financial statements as of and for the year ended December 31, 2022. The Audit Committee has also discussed with the independent registered public accounting firm, Ernst & Young LLP, the matters required to be discussed by Auditing Standard No. 1301, Communications with Audit Committees, issued by the Public Company Accounting Oversight Board and the SEC. In addition, the Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence and has discussed with the independent registered public accounting firm the independent registered public accounting firm’s independence.

Based upon these reviews and discussions, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022.

Pre-approval Policies and Procedures

Our Audit Committee implemented a policy to pre-approve all audit and permissible non-audit services provided by our independent registered public accounting firm. All of the services provided were pre-approved to the extent required. During the approval process, the Audit Committee considered the impact of the types of services and the related fees on the independence of the independent registered public accounting firm. The services and fees had to be deemed compatible with the maintenance of that firm’s independence, including compliance with rules and regulations of the SEC.
