1. DESCRIPTION OF BUSINESS AND PRESENTATION OF FINANCIAL STATEMENTS
Description of Business

Tarsus Pharmaceuticals, Inc. (“Tarsus” or the “Company”) is a biopharmaceutical company focused on the development and commercialization of therapeutics, starting with eye care. The Company’s operations currently consist of its preclinical and clinical studies, corporate administration and commercial leadership supporting planned business growth.
Liquidity

The Company has a limited operating history, no product sales and has accumulated losses and negative cash flows from operations since inception. The Company has funded its inception-to-date operations through equity capital raises; including the Company's initial public offering in 2020 and the follow-on public offering completed in May 2022 (see Note 5), proceeds from its out-license agreement, and draws from its credit facility. The Company estimates that its existing capital resources will be sufficient to meet projected operating expense requirements for at least 12 months from the filing date of the accompanying Condensed Financial Statements in this Form 10-Q, which have been prepared on a going-concern basis.

Management expects the Company to continue to incur operating losses for the foreseeable future and may be required to raise additional capital to fund its ongoing operations. However, no assurance can be given as to whether financing will be available on terms acceptable to the Company, or at all. If the Company is unable to raise additional funds as required, it may need to delay, reduce, or terminate some or all of its development programs and clinical trials. The Company may also be required to sell or license its rights to product candidates in certain territories or indications that it would otherwise prefer to develop and commercialize on its own and/or enter into collaborations and other arrangements to address its liquidity needs, which could materially and adversely affect its business and financial prospects, or even its ability to remain a going concern.
Operating Segment
To date, the Company has operated, managed and organized its business and financial information on an aggregate basis for the purposes of evaluating financial performance and the allocation of capital and personnel resources. The Company’s chief operating decision-maker (CODM), its Chief Executive Officer, reviews its operating results for the purpose of allocating resources and evaluating financial performance. Accordingly, the Company’s management determined that it operates one reportable operating segment.
Emerging Growth Company Status
The Company is an "emerging growth company," as defined in the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. The Company has irrevocably elected to not take this exemption. As a result, it will adopt new or revised accounting standards on the relevant effective dates on which adoption of such standards is required for other public companies that are not emerging growth companies.
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES AND USE OF ESTIMATES
(i) Basis of Presentation
The Company’s Condensed Financial Statements have been prepared in conformity with generally accepted accounting principles ("GAAP") in the United States ("U.S.") for interim financial information pursuant to Form 10-Q and with the rules and regulations of the Securities and Exchange Commission ("SEC"). Accordingly, the accompanying Condensed Financial Statements do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited financial statements and the related notes thereto in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the SEC on March 17, 2023.

TARSUS PHARMACEUTICALS, INC.
NOTES TO THE FINANCIAL STATEMENTS
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)
(Unaudited)
The interim Condensed Balance Sheet as of March 31, 2023, the interim Condensed Statements of Operations and Comprehensive Loss, the interim Condensed Statements of Stockholders’ Equity, and the interim Condensed Statements of Cash Flows for the three months ended March 31, 2023 and 2022, are unaudited. These unaudited interim financial statements have been prepared on the same basis as the Company’s annual financial statements and, in the opinion of management, reflect all adjustments, which consist of only normal and recurring adjustments for the fair presentation of its financial information.
The financial data and other information disclosed in these notes related to the three-month periods are also unaudited. The Condensed Balance Sheet as of December 31, 2022 has been derived from the audited financial statements at that date but does not include all information and footnotes required by GAAP for annual financial statements. The condensed interim operating results for three months ended March 31, 2023 are not necessarily indicative of results to be expected for the year ending December 31, 2023 or any other interim or annual period.

The preparation of financial statements in conformity with GAAP and with the rules and regulations of the SEC requires management to make informed estimates and assumptions that affect the amounts reported in these financial statements and accompanying notes. These estimates and assumptions are based upon historical experience, knowledge of current events and various other factors believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities and the recording of expenses that are not readily apparent from other sources and involve judgments with respect to numerous factors that are difficult to predict and may materially differ from the amounts ultimately realized and reported due to the inherent uncertainty of any estimate or assumption. Actual results could differ materially from those estimates.

The Company’s financial statements as of and for the year ended December 31, 2022, reflect the Company’s estimates of the impact of the macroeconomic environment, including the impact of inflation, higher interest rates, and foreign exchange rate fluctuations. The duration and the scope of these conditions cannot be predicted; therefore, the extent to which these conditions will directly or indirectly impact the Company’s business, results of operations and financial condition, is uncertain. The Company is not aware of any specific event or circumstance that would require an update to its estimates, judgments and assumptions or a revision of the carrying value of the Company’s assets or liabilities as of the issuance date of the accompanying Condensed Financial Statements.

Certain amounts in the prior years' financial statements have been reclassified to conform to the current year presentation. The Company reclassified license fees revenue and collaboration revenue which were historically separate financial statement line items on the Company's Statements of Operations and Comprehensive Loss and are now presented as a single revenue line— license fees and collaboration revenue. These reclassifications have no impact on total revenue or net loss.

There have been no significant changes in the Company’s significant accounting policies during the three months ended March 31, 2023, as compared with those disclosed in its Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 17, 2023, except as discussed below. The accounting policies and estimates that most significantly impact the presented amounts within the accompanying Condensed Financial Statements are further described below.
(ii) Cash and Cash Equivalents

Cash and cash equivalents consist of bank deposits and highly liquid investments, including money market fund accounts, that are readily convertible into cash without penalty, with original maturities of three months or less from the purchase date. The carrying amounts reported in the accompanying Condensed Balance Sheets for cash and cash equivalents are valued at cost, which approximate their fair value.
(iii) Marketable Securities and Long-Term Investments
Marketable securities consist of short-term fixed income investments carried at estimated fair value as determined based upon quoted market prices or pricing models for similar securities (see Note 3). Management determines the appropriate classification of its investments in fixed income securities at the time of purchase. Available-for-sale securities are classified as current assets on the accompanying Condensed Balance Sheets due to their highly liquid nature and availability for use in current operations.
F-7
Table of Contents
TARSUS PHARMACEUTICALS, INC.
NOTES TO THE FINANCIAL STATEMENTS
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)
(Unaudited)
Marketable securities are recorded at fair value with unrealized losses and gains reported as a component of accumulated other comprehensive loss within the accompanying Condensed Statements of Stockholders' Equity until realized. The Company periodically evaluates whether declines in fair values of its available-for-sale securities below their book value are other-than-temporary. This evaluation consists of several qualitative and quantitative factors regarding the severity and duration of the unrealized loss as well as the Company’s ability and intent to hold the available-for-sale security until a forecasted recovery occurs. The cost of debt securities is adjusted for amortization of premiums and accretion of discounts to maturity. Such amortization and accretion, as well as interest and dividends, are included in interest income. Realized losses and gains as well as credit losses, if any, on marketable securities identified on a specific identification basis and are included in other income (expense), net on the accompanying Condensed Statement of Operations and Comprehensive Loss. The Company evaluated the underlying credit quality and credit ratings of the issuers during the period. To date, the Company has not identified any other than temporary declines in fair value of its investments and no credit losses associated with credit risk have occurred or have been recorded. Interest earned on marketable securities is included in interest income within the accompanying Condensed Statements of Operations and Comprehensive Loss.

Long-term investments consist of holdings of common stock in the publicly-traded parent company of LianBio Ophthalmology Limited ("LianBio"), reflecting the intent to hold these shares for at least one year from the balance sheet date. These equity securities are designated as available-for-sale with associated gains or losses reported in other income (expense), net within the Condensed Statements of Operations and Comprehensive Loss for each reported period.
(iv) Fair Value Measurements
Assets and liabilities recorded at fair value on a recurring basis in the balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows:
•Level 1: Quoted prices (unadjusted) in active markets for identical assets or liabilities that are publicly accessible at the measurement date.
•Level 2: Observable prices that are based on inputs not quoted on active markets, but that are corroborated by market data. These inputs may include quoted prices for similar assets or liabilities or quoted market prices in markets that are not active to the general public.
•Level 3: Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
The carrying amounts for financial instruments consisting of cash, cash equivalents, short-term marketable securities, long-term investments, accounts payable and accrued liabilities approximate fair value due to the short maturities for each. The Company's equity warrant holdings disclosed as other assets are carried at fair value based on unobservable market inputs (see Note 3).
Assets and liabilities are classified based on the lowest level of input that is significant to the fair value measurements. The Company reviews the fair value hierarchy classification on a quarterly basis. Changes in the ability to observe valuation inputs may result in a reclassification of levels for certain assets or liabilities within the fair value hierarchy. The Company did not have any transfers of assets and liabilities between the levels of the fair value hierarchy during the years presented.

(v) Property and Equipment, Net

Property and equipment, net are stated at historical cost less accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful lives of the assets that range from three to five years. Leasehold

NOTES TO THE FINANCIAL STATEMENTS
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)
(Unaudited)
improvements are amortized on a straight-line basis over the shorter of the remaining lease term or the estimated useful lives of related improvements. The Company evaluates the recoverability of its property and equipment, net whenever events or changes in circumstances of the business indicate that the asset’s carrying amount may not be recoverable. Recoverability of these assets is measured by a comparison of the carrying amounts to the sum of the future undiscounted cash flows the assets are expected to generate over the remaining useful lives of the assets. If a long-lived asset fails a recoverability test, the Company measures the amount by which the carrying value of the asset exceeds its fair value. There were no impairments recognized during the three months ended March 31, 2023 and 2022.
(vi) Concentration of Credit Risk and Other Risks and Uncertainties

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash, cash equivalents and marketable securities. The Company maintains cash held in deposit at financial institutions in the U.S., including Silicon Valley Bank ("SVB"). As of March 31, 2023 and December 2022, the Company held cash and cash equivalents in its depository accounts of $8.1 million and $15.0 million, respectively. These deposits are insured by the Federal Deposit Insurance Corporation ("FDIC") in an amount up to $250,000 for any depositor. To the extent the Company holds cash deposits in amounts that exceed the FDIC insurance limitation, it may incur a loss in the event of a failure of any of the financial institutions where it maintains deposits.
The Company's monitoring ongoing events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, including SVB. On March 10, 2023, SVB was closed by the California Department of Financial Protection and Innovation, which appointed the FDIC as receiver, and all of SVB’s deposits and substantially all of SVB’s assets were transferred into a new entity, Silicon Valley Bridge Bank, N.A. (“SVBB”). On March 12, 2023, the Department of the Treasury, the Federal Reserve and the FDIC jointly released a statement that depositors at SVB would have access to their funds, even those in excess of the standard FDIC insurance limits, under a systemic risk exception. Such parties also announced, among other items, that SVBB had assumed the obligations and commitments of former SVB and commitments to advance under existing credit agreements with former SVB will be honored by SVBB pursuant to the terms of such credit agreements. On March 27, 2023, First Citizens Bank assumed all of SVBB’s obligations and commitments, and SVBB began operating as Silicon Valley Bank, a division of First Citizens Bank. Unless otherwise noted herein, all references to SVB or Silicon Valley Bank shall refer to Silicon Valley Bank, a division of First Citizens Bank. In light of the foregoing, the Company does not believe it has exposure to loss as a result of SVB’s receivership.

Management believes the Company is not exposed to significant credit risk due to the financial position of the depository institution, but will continue to monitor regularly and adjust, if needed, to mitigate risk. The Company has established guidelines regarding diversification of its investments and their maturities, which are designed to maintain principal and maximize liquidity. To date, the Company has not experienced any losses associated with this credit risk and continues to assess that this exposure is not significant.
(vii) Revenue Recognition for Out-License Arrangements
    
Overview

The Company currently has no product revenue. Reported revenue in the accompanying Condensed Statements of Operations and Comprehensive Loss is associated with one out-license agreement (the "China Out-License") that allows the third-party licensee to market the Company's TP-03 product candidate (representing functional intellectual property) in the People's Republic of China, Hong Kong, Macau, and Taiwan (the "China territory")— see Note 9. The accounting and reporting of revenue for out-license arrangements requires significant judgment for: (a) identification of the number of performance obligations within the contract, (b) the contract’s transaction price for allocation (including variable consideration), (c) the stand-alone selling price for each identified performance obligation, and (d) the timing and amount of revenue recognition in each period.

The China Out-License was analyzed under GAAP to determine whether the promised goods or services are distinct or must be accounted for as part of a combined performance obligation. In making these assessments, the Company considers factors such as the stage of development of the underlying intellectual property and the capabilities of the customer to develop the intellectual property on their own, and/or whether the required expertise is readily available. If the license is not distinct, the license is combined with other promised goods or services as a combined performance obligation for revenue recognition.

NOTES TO THE FINANCIAL STATEMENTS
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)
(Unaudited)
The China Out-License arrangement included the following forms of consideration: (i) non-refundable upfront license payment, (ii) equity-based consideration, (iii) sales-based royalties, (iv) sales-based threshold milestones, (v) one-time payments for executing drug supply agreements, (vi) development milestone payments, and (vii) regulatory milestone payments. Revenue is recognized in proportion to the allocated transaction price when (or as) the respective performance obligation is satisfied. The Company evaluates the progress related to each milestone at each reporting period and, if necessary, adjusts the probability of achievement and related revenue recognition. The measure of progress, and thereby periods over which revenue is recognized, is subject to estimates by management and may change over the course of the agreement.


Contractual Terms for Receipt of Payments

A performance obligation is a promise in a contract to transfer a distinct good or service and is the unit of accounting. A contract’s transaction price is allocated among each distinct performance obligation based on relative standalone selling price and recognized when, or as, the applicable performance obligation is satisfied.

The contractual terms that establish the Company’s right to collect specified amounts from its customers and that require contemporaneous evaluation and documentation under GAAP for the corresponding timing and amount of revenue recognition, are as follows:

(1) Upfront License Fees: The Company determines whether non-refundable license fee consideration is recognized at the time of contract execution (i.e., when the license is transferred to the customer and the customer is able to use and benefit from the license) or over the actual (or implied) contractual period of the China Out-License. The Company also evaluates whether it has any other requirements to provide substantive services that are inseparable from the performance obligation of the license transfer to determine whether any combined performance obligation is satisfied over time or at a point in time. Upfront payments may require deferral of revenue recognition to a future period until the Company performs obligations under these arrangements.

(2) Development Milestones: The Company utilizes the most likely amount method to estimate the amount of consideration to which it will be entitled for achievement of development milestones as these represent variable consideration. For those payments based on development milestones (e.g., patient dosing in a clinical study or the achievement of statistically significant clinical results), the Company assesses the probability that the milestone will be achieved, including its ability to control the timing or likelihood of achievement, and any associated revenue constraint. Given the high degree of uncertainty around the occurrence of these events, the Company determines the milestone and other contingent amounts to be constrained until the uncertainty associated with these payments is resolved. At each reporting period, the Company re-evaluates this associated revenue recognition constraint. Any resulting adjustments are recorded to revenue on a cumulative catch-up basis, and reflected in the financial statements in the period of adjustment.

(3) Regulatory Milestones: The Company utilizes the most likely amount method to estimate the consideration to which it will be entitled and recognizes revenue in the period regulatory approval occurs (the performance obligation is satisfied) as these represent variable consideration. Amounts constrained as variable consideration are included in the transaction price to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The Company evaluates whether the milestones are considered probable of being reached and not otherwise constrained. Accordingly, due to the inherent uncertainty of achieving regulatory approval, associated milestones are deemed constrained for revenue recognition until achievement.

(4) Royalties: Under the sales-or-usage-based royalty exception the Company recognizes revenue based on the contractual percentage of the licensee’s sale of products to its customers at the later of (i) the occurrence of the related product sales or (ii) the date upon which the performance obligation to which some or all of the royalty has been allocated has been satisfied or partially satisfied. To date, the Company has not recognized any royalty revenue from the China Out-License.

(5) Sales Threshold Milestones: Similar to royalties, applying the sales-or-usage-based royalty exception, the Company recognizes revenue from sales threshold milestones at the later of (i) the period the licensee achieves the one-time annual product sales levels in their territories for which the Company is contractually entitled to a specified lump-sum receipt,

(Unaudited)
or (ii) the date upon which the performance obligation to which some or all of the milestone has been allocated has been satisfied or partially satisfied. To date, the Company has not recognized any sales threshold milestone revenue from the China Out-License.

The Company re-evaluates the measure of progress to each performance obligation in each reporting period as uncertain events are resolved and other changes in circumstances occur.
(viii) Research and Development Costs

Research and development costs are expensed as incurred or as certain upfront or milestone payments become contractually due to licensors upon the achievement of clinical or regulatory events. Research and development expenses include internal costs directly attributable to in-development programs, including costs of certain salaries and other employee-related costs (including stock-based compensation), and costs to conduct nonclinical studies, clinical trials and contract manufacturing activities. The Company accrues these costs based on factors such as estimates of the work completed and in accordance with agreements established with third-party service providers under the service agreements. As it relates to clinical trials, the financial terms of these contracts are subject to negotiations which vary from contract to contract and may result in payment flows that do not match the periods over which materials or services are provided under such contracts. Payments made prior to the receipt of goods or services to be used in research and development are capitalized until the goods or services are received. Such payments are evaluated for current or long-term classification based on when they will be realized. The Company's objective is to reflect the appropriate expense in its financial statements by matching those expenses with the period in which the services and efforts are expended. The Company accounts for these expenses according to the progress of the trial as measured by patient progression and the timing of various aspects of the trial taking into consideration discussions with applicable personnel and outside service providers. The clinical trial accrual is dependent in part upon the timely and accurate reporting of progress and efforts incurred from contract research organizations ("CROs"), contract manufacturers and other third-party vendors. Although estimates are expected to be materially consistent with actual amounts incurred, the Company's understanding of the status and timing of services performed relative to the actual status and timing of services performed can vary and may result in changes in estimates in any particular period. The Company makes significant judgments and estimates in determining the accrued liabilities balance at each reporting period. As actual costs become known, the Company adjusts its accrued liabilities. To date, there have been no material differences between estimates of such expenses and the amounts actually incurred.
(ix) Stock-Based Compensation

The Company recognizes stock-based compensation expense for equity awards granted to employees, consultants, and members of its Board of Directors. Stock option awards are at an exercise price of not less than 100% of the fair market value of common stock on the respective date of grant. The grant date is the date the terms of the award are formally approved by the Company’s Board of Directors or its designee. The Company uses the Black-Scholes option pricing model to estimate the fair value of stock option awards as of the date of grant. The fair value of restricted stock units is representative of the closing market price of the Company's stock on the date preceding the award grant date.

Stock awards granted typically have one to four-year service conditions and a contractual term of 10 years. Any performance conditions for vesting are explicitly stated in each award agreement and are associated with clinical, business development, or operational milestones. For stock-based awards that vest subject to the satisfaction of a service requirement, the related expense is recognized on a straight-line basis over each award’s actual or implied vesting period. For stock-based awards that vest subject to a performance condition, the Company recognizes related expense on an accelerated attribution method, if and when it concludes that it is highly probable that the performance condition will be achieved. At each reporting period, the Company reassesses the probability of the achievement of the performance vesting conditions. As applicable, the Company reverses previously recognized expense for unvested awards in the same period of forfeiture.
All stock-based compensation expense is reported in the accompanying Condensed Statements of Operations and Comprehensive Loss within research and development expense or general and administrative expense, based upon the assigned department of the award recipient. The measurement of the fair value of stock option awards and recognition of stock-based compensation expense requires assumptions to be estimated by management that involve inherent uncertainties and the application of management’s judgment, including:
F-11
Table of Contents
TARSUS PHARMACEUTICALS, INC.
NOTES TO THE FINANCIAL STATEMENTS
(all tabular amounts presented in thousands, except share, per share, per unit, and number of years)
(Unaudited)
Fair Value of Common Stock — Subsequent to the IPO, the fair value of the Company’s common stock is based on the closing quoted market price of its common stock as reported by the Nasdaq Global Select Market on the date of the option grant.
Expected Term — The Company’s expected term represents the period that the Company’s stock option awards are expected to be outstanding. Management estimates the expected term of awarded stock options utilizing the simplified method (based on the mid-point between the vesting date and the end of the contractual term) to determine the expected term since the Company does not yet have sufficient exercise history. 
Expected Volatility — Prior to 2023, the Company did not have sufficient trading history for its common stock to use its own historical volatility. Management estimated the expected volatility based on a designated peer-group of publicly-traded companies for a look-back period (from the date of grant) that corresponded with the expected term of the awarded stock option. Beginning in January 2023, the Company began using its own historical stock price for expected volatility.
Risk-Free Interest Rate — The Company estimates the risk-free interest rate based upon the U.S. Department of Treasury yield curve in effect at award grant date for the time period that corresponds with the expected term of the awarded stock option.
Dividend Yield — The Company’s expected dividend yield is zero because it has never paid cash dividends and does not expect to for the foreseeable future.
(x) Net Loss per Share
Basic net loss per share is calculated by dividing the net loss by the weighted-average number of shares of common stock outstanding for the period, without consideration for potential dilutive shares of common stock. Diluted net loss per share is computed by dividing the net loss by the weighted-average number of common stock equivalents outstanding for the period determined using the treasury-stock method and if-converted method as applicable.

Due to a net loss for the three months ended March 31, 2023 and 2022, all otherwise potentially dilutive securities are antidilutive, and accordingly, the reported basic net loss per share equals the reported diluted net loss per share in each period presented.
(xi) Comprehensive Loss
Comprehensive loss represents (i) net loss for the periods presented, and (ii) unrealized gains or losses on the Company's reported available-for-sale debt securities.
(xii) Recently Issued or Effective Accounting Standards
Recently issued or effective accounting pronouncements that impact, or may have an impact, on the Company’s financial statements have been discussed within the footnote to which each relates. Other recent accounting pronouncements not disclosed in these Condensed Financial Statements have been determined by the Company’s management to have no impact, or an immaterial impact, on its current financial position, results of operations, or cash flows.

Money Market Funds and U.S. Treasury Securities

Money market funds and U.S. Treasury securities are highly liquid investments and are actively traded with readily-available market prices that are publicly observable and independently validated as of the measurement date. This approach results in the classification of these securities as Level 1 of the fair value hierarchy.
Commercial Paper, Corporate Debt Securities and Government-related Debt Securities

Commercial paper, corporate debt securities and government-related debt securities were valued using Level 2 inputs that utilized industry standard valuation models, including both income and market-based approaches, for which all significant inputs are observable, either directly or indirectly, to estimate fair value. The Company reviews trading activity and pricing for these investments as of each measurement date.
LianBio Common Stock and Equity Warrants
In March 2021, contemporaneous with the China Out-License transaction (see Note 9), the Company and LianBio, executed a warrant agreement for the Company to purchase, in three tranches, common shares in LianBio at an exercise price equal to common stock par value, which converted into warrants of the parent company of LianBio (LianBio, a pharmaceutical company focused on the Greater China and other Asian markets; Nasdaq: LIAN; any references to common stock or warrants of LianBio shall refer to common stock or warrants of the publicly-traded parent of LianBio) in connection with LianBio's previous Initial Public Offering. The first two tranches were vested and exercised as of December 31, 2022 and converted into 156,746 shares of LianBio common stock as recognized at fair value within long-term investments on the Condensed Balance Sheets as of March 31, 2023 and December 31, 2022. LianBio common stock is classified within Level 1 of the fair value hierarchy, given its publicly reported price on the Nasdaq Global Market.
The third warrant tranche will vest upon the achievement of a regulatory event and is presented within other assets in the accompanying Condensed Balance Sheets as of March 31, 2023 and December 31, 2022. This warrant tranche remains classified as Level 3 in the fair value hierarchy. The most significant assumptions used in the option pricing valuation model as

(Unaudited)
In March 2023, a clinical milestone was triggered to Elanco under the Eye and Derm Agreement upon enrollment of the first patient in the Phase 2a Galatea trial, evaluating the potential treatment of rosacea. The related milestone of $1.0 million was included in research and development expense on the accompanying Condensed Statements of Operations and Comprehensive Loss for the three months ended March 31, 2023. The milestone achievement fully offset a $0.6 million remaining prepayment and $0.4 million was recognized in accounts payable and other accrued liabilities on the accompanying Condensed Balance Sheets as of March 31, 2023.

As of March 31, 2023, the Company is obligated to make further cash payments to Elanco of $2.4 million under the Eye and Derm Elanco Agreement upon achievement of the last clinical milestone in the treatment of human skin diseases using lotilaner and a maximum of $79.0 million for various commercial and sales threshold milestones for the treatment of human skin diseases and the treatment of blepharitis in humans using lotilaner. In addition, the Company will be obligated to pay tiered contractual royalties to Elanco in the mid to high single digits of its net sales. If the Company receives certain types of payments from its sublicensees, it will be obligated to pay Elanco a variable percentage in the low to mid double-digits of such proceeds, until achievement of the first applicable regulatory approval of a product covered under the license.

September 2020 Agreement for All Other Diseases or Conditions in Humans

In September 2020, the Company executed a license agreement with Elanco granting it a worldwide license to certain intellectual property for the development and commercialization of lotilaner for the treatment, palliation, prevention, or cure of all other diseases and conditions in humans (i.e., beyond that of the eye or skin), as amended in June 2022 (the "All Human Uses Elanco Agreement"). In September 2020, the Company issued Elanco 222,460 shares of its common stock with an estimated fair value of $3.1 million ($14.0003 per share, approximating the issuance price of the Company's Series C preferred stock in September 2020).

The Company's made cash payments under the All Human Uses Elanco Agreement of $0.5 million related to a clinical milestone that was triggered in December 2022 upon enrollment of the first patient in the Phase 2a Carpo trial, for the treatment of Lyme disease. The Company is required to make further cash payments under this agreement upon the achievement of various clinical milestones for an aggregate maximum of $4.0 million and various commercial and sales threshold milestones for an aggregate maximum of $77.0 million. In addition, the Company will be obligated to pay contractual royalties to Elanco in the single digits of its net product sales. If the Company receives certain types of payments from its sublicensees, it will also be obligated to pay Elanco a variable percentage in the low to mid double-digits of such proceeds, until achievement of the first applicable regulatory approval of a product covered under the license.


Employment Agreements
The Company has entered into employment agreements with seven of its executive officers. These agreements provide for the payment of certain benefits upon separation of employment under specified circumstances, such as termination without cause, or termination in connection with a change in control event.
Consulting Agreements

The Company has a preexisting consulting agreement with a board member that was appointed in December 2021. This consulting agreement provides for annual cash compensation of approximately $0.2 million and option grants to purchase 45,134 shares of the Company’s common stock, with exercise prices ranging from $2.01 to $34.72 per share.

Litigation Contingencies
From time to time, the Company may be subject to various litigation and related matters arising in the ordinary course of business. The Company is currently not aware of any such matters where there is at least a reasonable probability that a material loss, if any, has been or will be incurred for financial statement recognition.
Indemnities and Guarantees
The Company has certain indemnity commitments, under which it may be required to make payments to its officers and directors in relation to certain transactions to the maximum extent permitted under applicable laws. The duration of these indemnities vary, and in certain cases, are indefinite and do not provide for any limitation of maximum payments. The Company has not been obligated to make any such payments to date and no liabilities have been recorded for this contingency in the accompanying Condensed Balance Sheets.
9. OUT-LICENSE AGREEMENT
Out-License of TP-03 Commercial Rights in the China Territory in March 2021

On March 26, 2021, the Company entered into The China Out-License agreement with LianBio for its exclusive development and commercialization rights of TP-03 (lotilaner ophthalmic solution, 0.25%) in the China Territory, as defined in the agreement, for the treatment of Demodex blepharitis and Meibomian Gland Disease. LianBio is contractually responsible for all clinical development and commercialization activities and costs within the China Territory.

The Company assessed this arrangement in accordance with ASC 606 and identified the following material promises under the arrangement: (i) the exclusive license to research, develop, manufacture, commercialize, make, offer for sale, sell, and import TP-03 in the China Territory, and (ii) the research and development services in the form of clinical study materials for the respective Phase 2b/3 trial (Saturn-1) and Phase 3 (Saturn-2) TP-03 trials. The promises to provide research and development services for Saturn-1 and Saturn-2 clinical trials were evaluated and determined to be distinct promises in the contract and each of the two clinical trials are separate performance obligations apart from the promise to provide the license.

The assessment of the initial transaction price for the China Out-License agreement included an analysis of amounts the Company expected to receive, which at contract inception consisted of: (i) the upfront cash payment of $15.0 million, (ii) a second cash payment of $10.0 million, (iii) a $10.0 million milestone that was determined to be within the control of the Company, and (iv) $1.2 million representing the initial fair value of the equity warrant.

The Company accounted for each performance obligation as follows:

Out-License

The Company determined that this license was distinct based on an evaluation of the delivery of the functional license that was in the later stages of development, and it met the criteria for being distinct from the research and development services required under the China Out-License agreement. The Company determined the standalone selling price of this license using a discounted projected sales model and recognized as license fees and collaboration revenue the total allocated transaction price at contract inception, upon delivery of the license.

Research and Development Services

The standalone selling price of these performance obligations was determined using the adjusted market assessment approach. The Company analyzed costs expected to be incurred for each of the clinical trials through completion to estimate the price that a customer would be willing to pay for these services in order to benefit from the clinical trials. The Company determined that LianBio simultaneously benefited from the research and development services that are satisfied over time, as they were able to request and access the clinical trial data at any point through the trial completion. Therefore, the Company recognized the amounts allocated to the respective research and development performance obligations for Saturn-1 and Saturn-2

as the research and development services were provided using an input method, based on the costs incurred for each clinical trial and the total costs expected to be incurred to satisfy each performance obligation. The Company believes this method most faithfully depicted its performance in transferring the promised services during the expected period of time that each clinical trial was ongoing. The Company monitored the expected completion dates for each clinical trial and updated its estimated time to completion at each reporting period, as necessary.

In February 2023, a specified milestone event was triggered resulting in $2.5 million recognized as license fees and collaboration revenue in the Condensed Statements of Operations for the three months ended March 31, 2023. This cash payment was received in the second quarter of 2023. Through March 31, 2023, the Company had received payments from LianBio totaling $80.0 million, comprised of initial consideration of $15.0 million and $65.0 million for the achievement of specified milestones.
As of March 31, 2023 the Company is eligible to receive further consideration from LianBio upon the achievement of additional TP-03 events, including: (i) additional regulatory milestone and one-time payments of up to an aggregate of $25.0 million (including the $2.5 million cash payment received in the second quarter of 2023), (ii) China-Based TP-03 sales threshold milestone payments of up to an aggregate of $100.0 million, (iii) tiered low-to-high-teen royalties for China Territory TP-03 product sales, and (iv) vesting of a LianBio equity warrant upon certain regulatory milestones.
Revenue recognized in the accompanying Condensed Statements of Operations and Comprehensive Loss relates to the satisfaction of performance obligations including (i) the transfer of TP-03 license rights in the China Territory to LianBio and (ii) the completion of U.S. clinical activities and then providing LianBio with the related data to supplement its local pivotal trial package for TP-03 in the treatment of Demodex blepharitis.
As part of the China Out-License with LianBio the Company granted Elanco an additional 187,500 shares of the Company's common stock that otherwise would have been issuable no later than the 18-month anniversary of the All Human Uses Elanco Agreement for its continued license exclusivity. These issued shares were valued at $5.5 million, based on the Company's closing stock price of $29.30 per share on the date this issuance became contractually required.

The Company made a contractual payment in the amount of $2.5 million to Elanco following the receipt of $25 million of proceeds from LianBio during the second quarter of 2021. During the fourth quarter of 2022, the Company recognized $0.4 million of cost of license fees and collaboration revenue upon receipt of $10 million of cash proceeds from LianBio for the achievement of a clinical development milestone.

The expenses recognized under the China-Out License were not material for the three month periods ended March 31, 2023 and 2022.

10. CREDIT FACILITY AGREEMENT

On February 2, 2022, the Company executed the Credit Facility with Hercules Capital, Inc. ("Hercules") and SVB that expires on February 2, 2027. Concurrent with the execution of the Credit Facility, the Company made a $20.0 million draw.

On January 5, 2023, the Company entered into an amendment to the loan and security agreement (the "First Amendment"). The First Amendment set a maximum interest rate, and updated the terms of prepayment under the Credit Facility and other certain specific conditions, including an extended period for the Company to draw down the $25.0 million tranche associated with the New Drug Application ("NDA") submission, from March 15, 2023 to March 15, 2024, provided at least $5.0 million was drawn on or before March 15, 2023 and at least an additional $5 million is drawn on or before September 15, 2023. The Company did not incur any lender fees as part of this First Amendment.

On March 15, 2023, the Company made a $5.0 million draw (including SVB's commitment of $1.25 million) from the $25.0 million tranche that became available upon submission of the NDA. As of March 31, 2023, the Credit Facility provides for a remaining aggregate principal amount of up to $130.0 million with tranched availability as follows: $20.0 million currently available related to the Company's NDA submission with the FDA for TP-03 in September 2022, $35.0 million available upon FDA approval of TP-03, $50.0 million available upon achievement of product net revenue thresholds, and $25.0 million available upon lender approval.

(Unaudited)

Each of these tranches may be drawn down in $5.0 million increments at the Company's election. The Credit Facility requires interest-only payments through February 1, 2026, followed by 12 months of principal amortization, unless extended for one year to its maturity, upon meeting certain contractual conditions. All unpaid amounts under the Credit Facility become due on its February 2, 2027 expiry.

Under the First Amendment, the outstanding principal draws accrue interest at a floating interest rate per annum equal to the greater of either (i) The Wall Street Journal ("WSJ") prime rate plus 4.45% with an aggregate cap of 11.45%, or (ii) 8.45%. At the execution date of the Credit Facility, the WSJ prime rate was 3.25% and increased to 8.00% as of March 31, 2023.

The Company is required to pay a specified fee upon the earlier of (i) February 2, 2027 or (ii) the date the Company prepays, in full or in part, the outstanding principal balance of the Credit Facility ("End of Term Charge"). The current End of Term Charge of $1.2 million was derived by multiplying 4.75% by the $25.0 million outstanding principal balance as of March 31, 2023 and is accreted to interest expense through maturity.

As of March 31, 2023 and 2022, the effective interest rate for the full term of the Credit Facility was 12.12% and 9.66%, respectively.

During the three months ended March 31, 2023 and 2022, the Company recognized interest expense on the accompanying Condensed Statements of Operations and Comprehensive Loss in connection with the Credit Facility as follows:

Three Months Ended
March 31, 2023		Three Months Ended March 31, 2022

Accretion of end of term charge53 32 
Amortization of debt issuance costs29 23 
Total interest expense related to term loan$684 $329 


The carrying value of the Credit Facility consists of principal outstanding less legal and administrative issuance costs that were recorded as a debt discount to the term loan, net and will continue to be accreted to interest expense using the effective interest method during its term. The principal balance of this Credit Facility and related accretion and amortization as of March 31, 2023 and December 31, 2022 are reported on a combined basis as term loan, net on the accompanying Condensed Balance Sheets as follows:

Overview
Our Business
We are a biopharmaceutical company focused on the development and commercialization of therapeutics, starting with eye care. Our lead product candidate, TP-03 (lotilaner ophthalmic solution, 0.25%), is a novel investigational eye drop to treat blepharitis caused by the infestation of Demodex mites, which is referred to as Demodex blepharitis. Blepharitis ("Blephar" is a reference to eyelid and “itis” is a reference to inflammation) is an ophthalmic lid margin disease characterized by inflammation of the eyelid margin, redness and ocular irritation, including a specific type of eyelash dandruff called collarettes, which are pathognomonic for Demodex blepharitis. Poorly controlled and progressive blepharitis can lead to corneal damage over time and, in extreme cases, blindness. There are an estimated 25 million people in the U.S. who suffer from Demodex blepharitis.

We designed TP-03 to target and eradicate the root cause of Demodex blepharitis — Demodex mite infestation. The active pharmaceutical ingredient ("API") of TP-03, lotilaner, paralyzes and eradicates mites and other parasites through the inhibition of parasite-specific gamma-aminobutyric acid-gated chloride ("GABA-Cl") channels.

To date, we have completed seven clinical trials that include a Phase 3 Saturn-2 trial, a Phase 2b/3 Saturn-1 trial, four Phase 2 trials, and a Phase 1 trial for TP-03 in Demodex blepharitis, all of which met their primary, secondary and/or certain exploratory endpoints, with the drug well tolerated throughout each trial. In November 2022, we announced the New Drug Application ("NDA") submission package for TP-03 for the treatment of Demodex blepharitis was accepted by the U.S. Food and Drug Administration ("FDA") with a PDUFA decision date of August 25, 2023. We believe TP-03 has the potential
25
Table of Contents
to be the first therapeutic approved by the FDA and become the definitive standard of care for the treatment of Demodex blepharitis.

We intend to further advance our pipeline with the lotilaner API to address several diseases across therapeutic and/or prophylactic categories in human medicine, including eye care, dermatology, and other diseases. We are investigating the development of product candidates to address targeted diseases with high unmet medical needs, which currently include TP-03 for the potential treatment of MGD, TP-04 for the potential treatment of rosacea, and TP-05 for potential Lyme disease prophylaxis and community malaria reduction.
Recent Business and Clinical Highlights

TP-03 Demodex Blepharitis, PDUFA August 25, 2023: Our sales force leadership infrastructure is in place for the potential upcoming commercial launch of TP-03 for the treatment of Demodex blepharitis, including the Vice President of Sales, two regional directors and eleven district managers. The sales force will be focused on targeting approximately 15,000 optometrists and ophthalmologists, which represents greater than 80% of the market.

•In March 2023, the Demodex Expert Panel on Treatment and Eyelid Health (“DEPTH”) published two papers on the importance of diagnosis and management of Demodex blepharitis Eye; https://doi.org/10.1038/s41433-023-02500-4, which showed the following:

◦Clinical diagnosis and management of Demodex blepharitis established consensus about the disease, including signs, symptoms and diagnosis;

◦DEPTH consensus regarding current clinical practice management options for Demodex blepharitis showed collarettes are pathognomonic, patients with greater than 10 collarettes should be treated even in the absence of symptoms and efficacy can be tracked by collarette resolution; and

◦DEPTH panel consensus was obtained by using the Delphi methodology, an approach that allows experts to achieve consensus by performing qualitative and quantitative analyses and utilizing sequential surveys.

•In March 2023, we presented health economics data at the Academy of Managed Care Pharmacy 2023, which suggests a costly, substantial burden of illness in patients with Demodex blepharitis and the need for a safe and effective FDA-approved treatment. The data presented included:

◦Ongoing disease impact and additional office visits are potentially driving up healthcare resource utilization;

◦Patients reported having delayed diagnosis, multiple office visits, unresolved Demodex blepharitis and high costs of disease management; and

◦Current non-FDA approved therapies to manage Demodex blepharitis do not address the root problem nor provide satisfactory relief for most patients.

•An Awareness, Trial and Usage (ATU) market research survey of approximately 250 optometrists and ophthalmologists was conducted to capture and analyze awareness and the likelihood to prescribe a potential prescription therapeutic for Demodex blepharitis, including:

◦Growing confidence in making a diagnosis with 68% believing collarettes are pathognomonic to Demodex blepharitis and 66% recognizing the importance of screening patients for the presence of collarettes during eye exams; and

◦93% indicated they would prescribe an FDA-approved therapeutic for Demodex blepharitis.

•We have raised awareness on the prevalence and impact of Demodex blepharitis through launching disease education campaigns, including:

◦The “Look at the Lids” disease education campaign, which generated nearly 200,000 unique website visits, up from 125,000 during the quarter ended December 31, 2022 and more than 2.3 million digital/media impressions, an increase of 300,000 impressions from the quarter ended December 31, 2022; and

26
Table of Contents
◦The “Don’t Freak Out. Get Checked Out.” disease education campaign, which was designed to encourage patients who may have Demodex blepharitis to visit their eye care provider for an eyelid check.

TP-03 Meibomian Gland Disease, Ersa Trial: In August 2022, we announced the enrollment of our first patient in the Phase 2a Ersa clinical trial studying TP-03 for the treatment of MGD. We expect to report topline data during the second half of 2023.

TP-04 Rosacea, Galatea Trial: In March 2023, we initiated the Galatea trial, a Phase 2a trial evaluating TP-04, a novel gel formulation of lotilaner, for the treatment of rosacea.

TP-05 Lyme Disease, Callisto and Carpo Trials: In December 2022, we announced positive topline results from the completed Phase 1 Callisto trial and enrollment of the first patient in the Phase 2a Carpo trial. The Callisto and Carpo trials are designed to evaluate TP-05, a novel investigative oral, non-vaccine pharmacological prophylactic for the potential prevention of Lyme disease. The Callisto Phase 1 trial was a randomized, double-blind, single and multiple-ascending dose trial that evaluated the safety, tolerability, and PK of TP-05 in healthy subjects. Results from the trial showed that TP-05 was well tolerated with no dose-related or drug-related serious adverse events. Pharmacokinetic data from the trial demonstrated rapid absorption and an extended half-life of TP-05 that potentially supports a convenient oral therapy regimen, supporting its potential as a rapid onset, prophylactic therapy for Lyme disease. Additionally, exploratory ex-vivo tick kill modeling utilizing serum from TP-05 treated subjects demonstrated potent, rapid killing of adult and nymph ticks. The Carpo trial, evaluating TP-05 for the potential prevention of Lyme disease in humans, is a randomized, double-blind trial that will evaluate the efficacy of TP-05 in killing lab grown, non-disease carrying ticks after they have attached to the skin of healthy volunteers, as well as confirm the safety, tolerability, and blood concentration of TP-05. We expect to report topline data from the Phase 2a Carpo trial during the second half of 2023.

We believe TP-05 is currently the only non-vaccine, drug-based prophylaxis in development that targets the ticks, and potentially prevents Lyme disease transmission. It is designed to rapidly and durably provide systemic blood levels of lotilaner potentially sufficient to kill infected ticks attached to the human body before they can transmit the Borrelia bacteria that causes Lyme disease.

TP-03 China Territory Out-License: In March 2021, we executed an out-license agreement (the "China Out-License") with LianBio Ophthalmology Limited ("LianBio"), granting exclusive commercial rights to TP-03 for the treatment of Demodex blepharitis and MGD within The People’s Republic of China, Macau, Hong Kong, and Taiwan (the "China Territory").

In February 2023, a specified milestone was triggered resulting in $2.5 million recognized as license fees and collaboration revenue in the accompanying Condensed Statements of Operations for the three months ended March 31, 2023. This cash payment was received in the second quarter of 2023. As of the date of this filing, we have received contractual cash proceeds from LianBio of $82.5 million (including the $2.5 million received in the second quarter of 2023), representing initial consideration of $15.0 million and $67.5 million for the achievement of specified milestone events. We also received equity in LianBio as part of this China Out-License, a portion of which remains subject to a China-based regulatory vesting provision.

Credit Facility with Hercules Capital and Silicon Valley Bank: On February 2, 2022, we executed a loan and security agreement with Hercules Capital, Inc. ("Hercules") and Silicon Valley Bank ("SVB") (the "Credit Facility). On January 5, 2023, we entered into an amendment to the loan and security agreement, which set a maximum interest rate, and updated the terms of prepayment under the Credit Facility and other certain specific conditions. On March 15, 2023, we made a $5.0 million draw (including SVB's commitment of $1.25 million) from the $25.0 million tranche that became available upon submission of the NDA. As of March 31, 2023, the Credit Facility provides for a remaining aggregate principal amount of up to $130.0 million (see Note 10). As further described below in the section titled “Impact of the COVID-19 Pandemic and the Macroeconomic Environment,” SVBB (as defined below) assumed the obligations and commitments of SVB, and subsequently, on March 27, 2023, First-Citizens Bank & Trust Company (“First Citizens Bank”) assumed all of SVBB’s obligations and commitments and SVBB began operating as Silicon Valley Bank, a division of First Citizens Bank. Unless otherwise noted herein, all references to SVB or Silicon Valley Bank shall refer to Silicon Valley Bank, a division of First Citizens Bank.

Corporate and Financial Overview
We were incorporated as a Delaware corporation in November 2016, and our headquarters is located in Irvine, California. Since our inception, we have devoted substantially all of our resources to organizing and staffing our company,
27
Table of Contents
acquiring intellectual property, clinical development of our product candidates, building our research and development capabilities, raising capital, and enhancing our corporate infrastructure.
To date we have financed our operations through private placements of preferred stock, convertible promissory notes, the net proceeds from issuance of common stock in our IPO and Follow-On Public Offering, cash proceeds from our China Out-License, and draw-downs from our Credit Facility.
We have incurred significant net operating losses in every year since our inception and expect to continue to incur significant operating expenses and, other than the effect of license fees and collaboration revenue from the China Out-License, increasing operating losses for the foreseeable future. Our net loss was $23.4 million and $20.2 million for the three months ended March 31, 2023 and 2022, respectively. Our net losses may fluctuate significantly from quarter to quarter and year to year and could be substantial. We anticipate that our operating expenses will increase significantly as we:
•seek regulatory approvals for TP-03 and other product candidates that successfully complete clinical development, if any;
•advance the clinical development of TP-03 for the potential treatment of MGD, TP-04 for the potential treatment of rosacea and TP-05 for potential Lyme prophylaxis;
•establish our own sales force in the U.S. to commercialize TP-03 upon regulatory approval and our other products for which we obtain such approvals;
•engage with contract manufacturers to ensure a sufficient supply chain capacity to provide commercial quantities of any products for which we may obtain marketing approval;
•maintain, expand and protect our intellectual property portfolio;
•hire additional staff, including clinical, scientific, technical, regulatory, marketing, operations, financial, and other support personnel, to execute our business plan; and
•add information systems and personnel to support our product development and potential future commercialization efforts, and to enable us to operate as a public company.
We do not yet have revenue from product sales. Our reported revenue within license fees and collaboration revenue is from our China Out-License; we expect to report additional revenue under this caption in future periods.
We do not expect to generate revenues from product sales unless and until we successfully complete clinical development and obtain regulatory approval for a product candidate and commercially launch such product. Until such time as we can generate significant revenue from product sales and achieve profitability, if ever, we expect to finance our operations through private or public equity or debt financings, or collaborations, strategic alliances, or licensing arrangements with third parties. Adequate funding may not be available to us when needed on acceptable terms, or at all. If we raise additional funds through collaborations, strategic alliances, or licensing arrangements with third parties, we may have to relinquish valuable rights to our intellectual property, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us. If we are unable to raise additional capital or enter into such agreements as and when needed, we could be forced to significantly delay, scale back, or discontinue our product development and/or commercialization plans, which would negatively and adversely affect our financial condition.
Because of the numerous risks and uncertainties associated with drug product development, we are unable to accurately forecast the timing or amount of increased expenses or when or if we will be able to achieve or maintain profitability. Even if we are able to generate revenue from product sales, we may not become profitable. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels.
As of March 31, 2023, our aggregate cash, cash equivalents and marketable securities was $201.2 million – see the section below titled “Management's Discussion and Analysis of Financial Condition and Results of Operations — Liquidity and Capital Resources.”
Impact of the COVID-19 Pandemic and Macroeconomic Environment
28
Table of Contents
We have been monitoring the COVID-19 pandemic and its potential impact on our business. To date, we have been able to continue our key business activities and advance our clinical programs. However, in the future, it is possible that our clinical development timelines and business plans could be adversely affected. We maintain regular communication with our vendors and clinical sites to appropriately plan for, and mitigate, the impact of the COVID-19 pandemic on our operations. While the pandemic has begun to subside, a resurgence in the COVID-19 pandemic, or other health epidemics or outbreaks in the future, could have a material, adverse impact on our commercialization and development timelines for our products and product candidates.
Further, the economic downturn resulting from the COVID-19 pandemic precipitated a global recession, and together with high rates of inflation and energy supply issues experienced in certain regions, have led to regional and/or global macroeconomic challenges, the effects of which may be of an extended duration.
In addition, we may be exposed to credit risk on deposits at financial institutions to the extent our account balances exceed the amount insured by the Federal Deposit Insurance Corporation (“FDIC”). We are monitoring ongoing events involving limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions, including SVB. On March 10, 2023, SVB was closed by the California Department of Financial Protection and Innovation, which appointed the FDIC as receiver, and all of SVB’s deposits and substantially all of SVB’s assets were transferred into a new entity, Silicon Valley Bridge Bank, N.A. (“SVBB”). On March 12, 2023, the Department of the Treasury, the Federal Reserve and the FDIC jointly released a statement that depositors at SVB would have access to their funds, even those in excess of the standard FDIC insurance limits, under a systemic risk exception. Such parties also announced, among other items, that SVBB had assumed the obligations and commitments of former SVB; commitments to advance under existing credit agreements with former SVB will be honored by SVBB pursuant to the terms of such credit agreements. On March 27, 2023, First Citizens Bank assumed all of SVBB’s obligations and commitments, and SVBB began operating as Silicon Valley Bank, a division of First Citizens Bank. In light of the foregoing, we do not believe we have exposure to loss as a result of SVB’s receivership.

See the section titled Risk Factors in our Annual Report on Form 10-K for the year ended December 31, 2022, filed with the SEC on March 17, 2023 and in this Quarterly Report, for a further discussion of the potential adverse impact of COVID-19 and unfavorable global economic conditions on our business, results of operations and financial condition.

Table of Contents
License Fees and Collaboration Revenue For the three months ended March 31, 2023 and 2022, we recognized $2.5 million and $0.5 million, respectively, of license fees and collaboration revenue under the China Out-License. These amounts represent the contractual milestones achieved or allocated under the China Out-License that have been fully or partially completed by the period end. These allocated amounts represented the satisfaction of the transfer of license rights to LianBio and the completion of related performance obligations.
We will recognize additional license fees and collaboration revenue to the extent other events occur, specifically related to (i) milestone achievement of an additional drug supply agreement execution, (ii) milestone achievement of certain regulatory events in the China Territory, and (iii) royalties and milestones from our licensee's product sales of TP-03 in the China Territory.
Cost of License Fees and Collaboration Revenue
Cost of license fees and collaboration revenue was $33 thousand for the three months ended March 31, 2022. This amount relates to our contractual payment obligations to Elanco, in proportion to our recognized license fees and collaboration revenue in the same period.

Total research and development expenses$12,356 $12,081 $275 
Research and development expenses increased by $0.3 million for the three months ended March 31, 2023, as compared to the prior year period. This increase was primarily due to (i) $2.8 million of increased indirect expenses related to payroll and personnel-related costs (including stock-based compensation) for 28 employee additions period over period to drive our product development initiatives, (ii) $1.0 million of milestone expense related to our in-license agreement with Elanco, and (iii) $1.8 million of increased TP-05 program expenses primarily related to a new food effect study that was initiated during the three months ended March 31, 2023 and other clinical trial initiatives. These increases were partially offset by decreases in direct external spend for the TP-03 and TP-04 programs of $4.9 million and $0.5 million, respectively. The decrease in our TP-03 program expenses was primarily due to significantly reduced clinical trial costs given the completion of our Saturn-2 trial in the first half of 2022. The decrease in our TP-04 program expenses were primarily due to decreases in preclinical costs.
General and Administrative Expenses

General and administrative expenses increased by $7.2 million for the three months ended March 31, 2023, as compared to the prior year period. The increase was primarily due to (i) $3.7 million of increased payroll and personnel-related costs (including stock-based compensation) for 31 corporate employee additions, period over period, to support our business growth and commercial leadership hires for readiness of our anticipated commercial launch of TP-03 in the second half of 2023, and (ii) $2.9 million of increased commercial and market research costs as we continue our commercial expansion and prepare for the potential launch of TP-03 in the second half of 2023, (iii) $0.2 million of increased IT application expenses to support the continued growth and expansion of our corporate infrastructure, and (iv) $0.2 million of increased facilities and other office and administrative expenses. We expect sales and marketing headcount and associated vendor expenses to meaningfully increase during 2023 as part of our TP-03 commercial launch-related activities.
Other Income (Expense), Net

Other income (expense), net increased by $2.2 million primarily due to (i) $2.3 million of increased interest income earned on our cash, cash equivalents and marketable securities, (ii) $0.2 million change in estimated fair value of the LianBio equity warrants we received as part of our China Out-License in March 2021, and (iii) $0.1 million change in fair value of the
30
Table of Contents
LianBio common stock. These increases were partially offset by a decrease of interest expense of $0.4 million on the Credit Facility.
Provision for Income Taxes
We maintain a valuation allowance against our net deferred tax assets as of March 31, 2023 and 2022 due to the uncertainty that such assets will be realized. We evaluate the recoverability of our deferred tax assets on at least an annual basis.
Liquidity and Capital Resources
Sources of Liquidity
Overview
As of March 31, 2023, we had cash, cash equivalents and marketable securities of $201.2 million. Since our inception, our operations have been substantially financed by cash proceeds of private placements of preferred stock, IPO proceeds from the issuance of common stock, China Out-License consideration, Credit Facility draws, and the Follow-On Public Offering.
IPO and Follow-On Public Offering
In connection with our October 2020 IPO, we sold 6,325,000 shares of our common stock (inclusive of the full exercise of the underwriters’ option to purchase 825,000 shares of common stock). After deducting underwriting discounts, commissions and other related expenses, our IPO proceeds were $91.7 million. In May 2022, we completed the Follow-On Public Offering. We also granted the underwriters a 30-day option to purchase up to 840,000 additional shares of common stock at the public offering price, less underwriting discounts and commissions. In June 2022, the underwriters partially exercised their option to purchase an additional 289,832 shares of common stock at the offering price of $13.50 per share, before underwriting discounts and commissions. After giving effect to the exercise of the underwriters’ option, we sold 5,889,832 shares for total gross proceeds of $79.5 million, before underwriting discounts, commissions and other estimated offering expenses for total net proceeds received of $74.3 million.
China Out-License
As of the date of this filing, we have received $82.5 million of total proceeds in connection with our China Out-License. We expect to receive an additional $2.5 million during 2023 for the achievement of a specific milestone, for cumulative milestone receipts of $85.0 million through December 2023. The remaining $120.0 million of available milestones under this arrangement will potentially be received upon future regulatory and sales achievements all within the China Territory.
Credit Facility

In February 2022, we drew $20.0 million from our Credit Facility with Hercules and SVB. Capital draws are at our election and are in $5.0 million increments. This Credit Facility was amended in January 2023. The Credit Facility, as amended, includes an extended period to draw down the tranche associated with the NDA submission, from March 15, 2023 to March 15, 2024 provided at least $5 million was drawn on or before March 15, 2023 and at least an additional $5 million is drawn on or before September 15, 2023. On March 15, 2023 we made a $5.0 million draw (including SVB's commitment of $1.25 million) from the $25.0 million tranche associated with the NDA submission of TP-03. The Credit Facility includes four-year period of interest-only payments and is extendable for a fifth year to February 2027 maturity, upon our expected achievement of required conditions. We currently have no other financing commitments, such as lines of credit or guarantees.

As of the date of this filing, we have $130.0 million of tranched availability as follows:

• $20.0 million, which became available in September 2022 upon our NDA submission of TP-03 to the FDA;
• $35.0 million available upon FDA approval of TP-03;
• $50.0 million available upon achievement of certain quarterly revenue thresholds; and
• $25.0 million available with lender approval.
Funding Requirements
Liquidity
31
Table of Contents
Our operating expenditures currently consist of research and development costs (including activities within our preclinical, clinical, regulatory, and drug manufacturing initiatives) and general and administrative costs. Our use of cash is impacted by the timing and extent of payments for each of these activities and other business requirements.

We believe that our cash and investments of $201.2 million as of March 31, 2023 is sufficient to fund our current and planned operations for at least the next twelve months from the date of this filing on Form 10-Q. Based upon this plan, we anticipate these funds in combination with our Credit Facility, revenues generated from TP-03, and milestones from the China Out-License to fund our commercial launch of TP-03 in Demodex blepharitis and advance our pipeline through Phase 2 studies in MGD, Lyme disease and rosacea.

We anticipate having at least $55.0 million of available capital from our Credit Facility through March 2024 and an additional $75.0 million of additional tranched availability through December 2024. The Credit Facility requires interest-only debt service payments that are expected to remain through its maturity in February 2027 and its remaining tranches are subject to undrawn expiry in either March 2024 or December 2024 (see Note 10).
Our cash runway estimate is predicated on current assumptions for future revenue, operating expenses, and debt availability and may require future adjustments. Accordingly, we may be required to raise additional capital earlier than we currently expect based on our cash requirements and market dynamics.
Shelf Registration Statement

On November 1, 2021, we filed a shelf registration statement on Form S-3 that was declared effective by the SEC on November 5, 2021 (the “Shelf Registration Statement”), which permitted us to offer up to $300.0 million of common stock, preferred stock, debt securities and warrants in one or more offerings and in any combination, including in units from time to time. We have approximately $220 million remaining under our Shelf Registration Statement, after giving effect to the Follow-On Public Offering (but inclusive of the sales agreement prospectus described below). Our Shelf Registration Statement is intended to provide us with additional flexibility to access capital markets for general corporate expenses and acquisitions of complementary products, technologies, or businesses. We completed the Follow-On Public Offering under this Shelf Registration Statement.

Also, as part of this Shelf Registration Statement, we concurrently filed a sales agreement prospectus covering the sale of up to $100.0 million of our common stock pursuant to an Open Market Sale AgreementTM (the “ATM Agreement”) with Jefferies LLC. Through the date of this filing, we have not sold any shares of our common stock under the ATM Agreement.

Other Liquidity Risks
To date, we have not generated any product sales, though we have recognized revenue and cash receipts from our China Out-License. We do not expect to report any product revenue unless and until we (i) complete development of any of our product candidates; (ii) obtain applicable regulatory approvals; and then (iii) successfully commercialize our product candidates or enter into other collaborative agreements for our product candidates with third parties. We do not know with certainty when, or if, any of these items will ultimately occur.
We expect to incur significant operating losses for the foreseeable future, and expect these losses to further increase, as we expand our clinical development programs and as we prepare for the potential commercial launch of TP-03. We may also encounter unforeseen expenses, difficulties, complications, delays and other currently unknown factors that could adversely affect our business.
We may require additional capital to fully develop our product candidates and to execute our business strategy. Our requirements of a future capital raise will depend on many factors, including:
•the amount of revenue, if any, received from commercial sales of our product candidates, should any of our product candidates receive marketing approval;
•the cost and timing associated with commercializing our product candidates, if they receive marketing approval;
•the scope, timing, rate of progress and costs of our drug discovery efforts, preclinical development activities, laboratory testing and clinical trials for our product candidates;
•the number and scope of clinical programs we decide to pursue;
32
Table of Contents
•the cost, timing and outcome of preparing for and undergoing regulatory review of our product candidates;
•the scope and costs of development and commercial manufacturing activities;
•the achievement of milestones or occurrence of other developments that trigger payments under any collaboration agreements we might have at such time and availability of our Credit Facility;
•the extent to which we acquire or in-license other product candidates and technologies;
•the costs of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending intellectual property-related claims;
•our ability to establish and maintain collaborations on favorable terms, if at all;
•our efforts to enhance operational systems and our ability to attract, hire and retain qualified personnel, including personnel to support the development of our product candidates and, ultimately, the sale of our products, following FDA approval;
•our implementation of various computerized information systems;
•impact of health epidemics, including COVID-19, on our clinical development or operations; and
•the costs associated with being a public company.
A change in the outcome of any of these or other variables with respect to the development of any of our product candidates could significantly change the costs and timing associated with the development of that product candidate. Furthermore, our operating plans may change in the future, and we will continue to require additional capital to meet operational needs and capital requirements associated with such operating plans. If we raise additional funds by issuing equity securities, our stockholders may experience dilution. Any future debt financing into which we enter may impose upon us additional covenants that restrict our operations, including limitations on our ability to incur liens or additional debt, pay dividends, repurchase our common stock, make certain investments or engage in certain merger, consolidation or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us or our stockholders.
Adequate funding may not be available to us on acceptable terms or at all. Our potential inability to raise capital when needed could have a negative impact on our financial condition and our ability to pursue our business strategies. If we are unable to raise additional funds as required, we may need to delay, reduce, or terminate some or all development programs and clinical trials. We may also be required to sell or license our rights to product candidates in certain territories or indications that we would otherwise prefer to develop and commercialize ourselves. If we are required to enter into collaborations and other arrangements to address our liquidity needs, we may have to give up certain rights that limit our ability to develop and commercialize our product candidates or may have other terms that are not favorable to us or our stockholders, which could materially and adversely affect our business and financial prospects. See the section titled “Risk Factors” in this report for additional risks associated with our substantial capital requirements.

Net Cash Used in Operating Activities
Net cash used in operating activities was $22.0 million for the three months ended March 31, 2023, which primarily consisted of our net loss of $23.4 million partially offset by stock-based compensation of $3.9 million. For the three months ended March 31, 2023, our cash payments to vendors totaled $15.2 million and payroll-related cash payments (inclusive of 2022 bonus payouts) totaled $10.4 million.

Net cash provided by operating activities was $15.3 million for the three months ended March 31, 2022. Though we recognized $0.5 million of license fee and collaboration revenue, no corresponding cash was received in connection with our China Out-License. In the prior year period, our cash payments to vendors for our operating activities totaled $10.1 million and payroll-related cash payments (inclusive of 2021 bonus payouts) totaled $5.2 million.

Net Cash Provided by (Used in) Investing Activities
Net cash provided by investing activities was $11.3 million for the three months ended March 31, 2023, and primarily relates to $40.3 million of proceeds from maturities of investments, partially offset by $28.7 million of purchased investments and $0.3 million of purchased furniture, fixtures and leasehold improvements for our laboratory and administrative offices.
Net cash used in investing activities was $0.2 million for the three months ended March 31, 2022, which consisted of leasehold improvements for our laboratory and administrative offices and various purchases of computer hardware and office equipment.

Net Cash Provided by Financing Activities
Net cash provided by financing activities was $5.0 million and $19.1 million for the three months ended March 31, 2023 and 2022, respectively, which substantially relates to proceeds from our Credit Facility.
Critical Accounting Policies, Significant Judgments and Use of Estimates

Our management's discussion and analysis of financial condition and results of operations is based on our Condensed Financial Statements, which have been prepared in conformity with U.S. generally accepted accounting principles ("GAAP") requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of these condensed 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. Actual results may differ materially from these estimates under different assumptions or conditions. A summary of our critical accounting policies is presented in our filed Annual Report on Form 10-K for the year ended December 31, 2022.
There were no material changes to our previously reported Critical Accounting Policies during the three months ended March 31, 2023.

Table of Contents
Recent Accounting Pronouncements
A description of recent accounting pronouncements that may potentially impact our financial position, results of operations or cash flows are disclosed in the footnote to which each relates within these accompanying Condensed Financial Statements.
Off-Balance Sheet Arrangements
Since our inception, we have not engaged in any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.
Indemnification Agreements
As permitted under Delaware law and in accordance with our bylaws, we indemnify our officers and directors for certain events or occurrences while the officer or director is or was serving in such capacity. We are also party to indemnification agreements with our officers and directors. We believe the fair value of the indemnification rights and agreements is minimal. Accordingly, we have not recorded any liabilities for these indemnification rights and agreements as of March 31, 2023.
JOBS Act Accounting Election
The Jumpstart Our Business Startups Act of 2012 permits an “emerging growth company” such as us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have irrevocably elected to opt out of this provision and, as a result, we will comply with new or revised accounting standards as required when they are adopted.
We will remain an emerging growth company until the earliest of (1) December 31, 2025, which is the last day of our first fiscal year following the fifth anniversary of the completion of our IPO, (2) the last day of our first fiscal year (a) in which we have total annual gross revenues of at least $1.235 billion or (b) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million, as of the prior June 30th and (3) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.
Item 3. Quantitative and Qualitative Disclosures about Market Risk
Interest Rate Risk
The market risk inherent in our financial instruments and in our financial position represents the potential loss arising from adverse changes in interest rates. As of March 31, 2023, we had cash, cash equivalents, and marketable securities of $201.2 million, consisting of interest-bearing money market accounts, U.S. Treasury securities, commercial paper, corporate debt securities and government-related debt securities for which the fair market value would be affected by changes in the general level of United States interest rates. However, due to the short-term maturities and the low-risk profile of our investments, an immediate 100 basis point change in interest rates would not have a material effect on the fair market value of our cash, cash equivalents and marketable securities.
As of March 31, 2023, we had $25.0 million of debt principal outstanding. Our Credit Facility bears interest at an annual rate equal to the greater of (i) the prime rate as reported in the Wall Street Journal plus 4.45% with an aggregate cap of 11.45% or (ii) 8.45%. A hypothetical interest rate of 20% would have resulted in reported interest expense of $1.3 million for the three months ended March 31, 2023.
We do not believe inflation, interest rate changes, and foreign currency exchange rate fluctuations had a significant impact on our results of operations for any periods presented herein. However, with further inflationary pressures, certain significant increased costs could have an adverse impact on the results of our operations.
Item 4. Controls and Procedures
Evaluation of Disclosure Controls and Procedures
35
Table of Contents
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 (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act of 1934, as amended ("Exchange Act")) as of the end of the period covered by this report. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective to provide reasonable assurance that 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 SEC’s rules and forms and to provide reasonable assurance that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.
Changes in Internal Control Over Financial Reporting
There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the period covered by this report that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
Inherent Limitations on Effectiveness of Controls
Our management, including our Chief Executive Officer and Chief Financial Officer, do not expect that our disclosure controls or our internal controls over financial reporting will prevent all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty, and that breakdowns can occur because of a simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of the controls. The design of any system of controls is also based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions, over time, controls may become inadequate because of changes in conditions, or the degree of compliance with policies or procedures may deteriorate. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.
