Note 1 – Basis of Presentation

The unaudited interim Consolidated Financial Statements of Proto Labs, Inc. (Protolabs, the Company, we, us or our) have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. In the opinion of management, the accompanying financial statements reflect all adjustments necessary for a fair presentation of the Company’s statements of financial position, results of operations and cash flows for the periods presented. Except as otherwise disclosed herein, these adjustments consist of normal, recurring items. Operating results for interim periods are not necessarily indicative of results that may be expected for the fiscal year as a whole.

The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and the related disclosures at the date of the financial statements and during the reporting period. Actual results could materially differ from these estimates. For further information, refer to the audited Consolidated Financial Statements and Notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2019 as filed with the Securities and Exchange Commission (SEC) on February 26, 2020.

The accompanying Consolidated Balance Sheet as of December 31, 2019 was derived from the audited Consolidated Financial Statements but does not include all disclosures required by U.S. GAAP for a full set of financial statements. This Form 10-Q should be read in conjunction with the Company’s Consolidated Financial Statements and Notes included in the Annual Report on Form 10-K filed on February 26, 2020 as referenced above.

Note 2 – Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

During the first quarter of 2020, the Company adopted the Financial Accounting Standards Board (FASB) Accounting Standards Update (ASU) 2016-13, Financial Instruments – Credit Losses, which is intended to provide financial statement users with more decision-useful information about the expected credit losses on financial instruments held by a reporting entity at each reporting date. The adoption of this guidance had no material impact on our consolidated financial statements.

During the fourth quarter of 2019, the Company early adopted the FASB ASU 2017-04, Intangibles – Goodwill and Other, which is intended to simplify the subsequent measurement of goodwill. The adoption of this guidance had no material impact on our consolidated financial statements.

Note 3 – Net Income per Common Share

Basic net income per share is computed based on the weighted-average number of common shares outstanding. Diluted net income per share is computed based on the weighted-average number of common shares outstanding, increased by the number of additional shares that would have been outstanding had potentially dilutive common shares been issued and reduced by the number of shares the Company could have repurchased from the proceeds from issuance of the potentially dilutive shares. Potentially dilutive shares of common stock include stock options, restricted stock units and restricted stock awards granted under stock-based compensation plans and shares committed to be purchased under the employee stock purchase plan. Performance stock units are excluded from the calculation of dilutive potential common shares until the performance conditions have been satisfied.

The table below sets forth the computation of basic and diluted net income per share:

Note 5 – Fair Value Measurements

Accounting Standards Codification (ASC 820), Fair Value Measurement (ASC 820), defines fair value as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. ASC 820 also establishes a fair value hierarchy that requires classification based on observable and unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

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 Company’s cash consists of bank deposits. The Company’s cash equivalents measured at fair value consist of money market mutual funds. The Company determines the fair value of these investments using Level 1 inputs.

The following table summarizes financial assets as of June 30, 2020 and December 31, 2019 measured at fair value on a recurring basis:

	*June 30, 2020*						*December 31, 2019*

Note 6 – Marketable Securities

The Company invests in short-term and long-term agency, municipal, corporate and other debt securities. The securities are categorized as held-to-maturity and are recorded at amortized cost, net of an allowance for credit losses. Categorization as held-to-maturity is based on the Company’s ability and intent to hold these securities to maturity. The following table summarizes information regarding the Company’s short-term and long-term marketable securities as of June 30, 2020 and December 31, 2019:

	*June 30, 2020*
(in thousands)	*Cost*		*Unrealized Gains*		*Unrealized Losses*			*Fair Value*
U.S. municipal securities	$	8,840	$	71	$	-		$	8,911

Total marketable securities	$	48,397	$	112	$	(22	)	$	48,487

Fair values for the corporate debt securities are primarily determined based on quoted market prices (Level 1). Fair values for the U.S. municipal securities, U.S. government agency securities, certificates of deposit and U.S. treasury securities are primarily determined using dealer quotes or quoted market prices for similar securities (Level 2).

During the first quarter of 2020, the Company adopted the FASB ASU 2016-13, Financial Instruments – Credit Losses. The Company calculated the expected credit loss for each security in its portfolio using the probability-of-default method. The Company concluded the adoption of the guidance had no material impact on its consolidated financial statements.

Classification of marketable securities as current or non-current is based upon the security’s maturity date as of the date of these financial statements.

The June 30, 2020 balance of held-to-maturity debt securities by contractual maturity is shown in the following table at amortized cost, net of an allowance for credit losses. Actual maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

	*June 30,*
(in thousands)	*2020*
Due in one year or less	$	33,128
Due after one year through five years		44,127
Total marketable securities	$	77,255

Note 7 – Inventory

Inventory consists primarily of raw materials, which are recorded at the lower of cost or market using the average-cost method, which approximates first-in, first-out (FIFO) cost.

Note 8 – Stock-Based Compensation

Under the Company’s 2012 Long-Term Incentive Plan, as amended (the 2012 Plan), the Company has the ability to grant stock options, stock appreciation rights (SARs), restricted stock, restricted stock units, other stock-based awards and cash incentive awards. Awards under the 2012 Plan have a maximum term of ten years from the date of grant. The compensation committee may provide that the vesting or payment of any award will be subject to the attainment of specified performance measures in addition to the satisfaction of any continued service requirements and the compensation committee will determine whether such measures have been achieved. The per-share exercise price of stock options and SARs granted under the 2012 Plan generally may not be less than the fair market value of a share of our common stock on the date of the grant.

Employee Stock Purchase Plan

The Company’s 2012 Employee Stock Purchase Plan (ESPP) allows eligible employees to purchase a variable number of shares of the Company’s common stock each offering period at a discount through payroll deductions of up to 15 percent of their eligible compensation, subject to plan limitations. The ESPP provides for six-month offering periods with a single purchase period ending May 15 and November 15, respectively. At the end of each offering period, employees are able to purchase shares at 85 percent of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last trading day of the offering period.

Stock-Based Compensation Expense

Stock-based compensation expense was $3.6 million and $3.5 million for the three months ended June 30, 2020 and 2019, respectively, and $6.7 million and $6.5 million for the six months ended June 20, 2020 and 2019, respectively.

Note 10 – Income Taxes

The Company is subject to income tax in multiple jurisdictions and the use of estimates is required to determine the provision for income taxes. For the three months ended June 30, 2020 and 2019, the Company recorded an income tax provision of $2.5 million and $4.5 million, respectively. For the six months ended June 30, 2020 and 2019, the Company recorded an income tax provision of $6.4 million and $8.7 million, respectively. The income tax provision is based on the estimated annual effective tax rate for the year applied to pre-tax income. The effective income tax rate for the three months ended June 30, 2020 was 16.6 percent compared to 21.9 percent in the same period of the prior year. The effective tax rate decreased by 5.3 percent for the three months ended June 30, 2020 when compared to the same period in 2019 primarily due to an increase in tax benefits from the vesting of restricted stock and the exercise of stock options and an increase in the research and development tax credit. The effective income tax rate for the six months ended June 30, 2020 was 19.4 percent compared to 21.5 percent in the same period of the prior year. The effective tax rate decreased by 2.1 percent for the six months ended June 30, 2020 when compared to the same period in 2019 primarily due to an increase in tax benefits from the vesting of restricted stock and the exercise of stock options and an increase in the research and development tax credit.

The effective income tax rate for the six months ended June 30, 2020 differs from the U.S. federal statutory rate of 21.0 percent due to various factors, including operating in multiple state and foreign jurisdictions and tax credits for which the Company qualifies.

The Company had unrecognized tax benefits totaling $4.7 million as of June 30, 2020 and $4.6 million as of December 31, 2019, respectively, all of which, if recognized, would affect the Company’s effective tax rate. The Company recognizes interest and penalties related to income tax matters in income tax expense, and reports the liability in current or long-term income taxes payable as appropriate.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act was signed into law on March 27, 2020. The CARES Act is meant to infuse companies with various income and payroll tax cash benefits to ease the impact of the pandemic. A technical correction to the Tax Cuts and Jobs Act of 2017 was included in the CARES Act allowing qualified improvement property to claim bonus depreciation for respective assets placed in service in 2018 and 2019. The impact of the CARES Act to the Company was a $2.6 million reduction in our income taxes payable and a corresponding increase to our deferred tax liability. In addition, the Company has elected to defer deposits of the employer portion of the Social Security tax for the quarter ended June 30, 2020 through the quarter ended December 31, 2020. The Social Security taxes are being accrued for and will be paid beginning in 2021.

Note 11 – Segment Reporting

The Company’s reportable segments are based on the internal reporting used by the Company’s Chief Executive Officer, who is the chief operating decision maker (CODM), to assess operating performance and make decisions about the allocation of resources. The Corporate Unallocated and Japan category includes non-reportable segments, as well as research and development and general and administrative costs that the Company does not allocate directly to its operating segments.

Intercompany transactions primarily relate to intercontinental activity and have been eliminated and are excluded from the reported amounts. The difference between income from operations and pre-tax income relates to foreign currency-related gains and losses and interest income on cash balances and investments, which are not allocated to business segments.

Revenue and income from operations by reportable segment for the three and six months ended June 30, 2020 and 2019 were as follows:

Overview

We are the world’s largest and fastest digital manufacturer of custom prototypes and on-demand production parts. We manufacture prototypes and low-volume production parts for companies worldwide, who are under increasing pressure to bring their finished products to market faster than their competition. We utilize injection molding, computer numerical control (CNC) machining, 3D printing and sheet metal fabrication to manufacture custom parts for our customers. Our proprietary technology eliminates most of the time-consuming and expensive skilled labor conventionally required to quote and manufacture parts. Our customers conduct nearly all of their business with us over the Internet. We target our products to the millions of product developers and engineers who use three-dimensional computer-aided design (3D CAD) software to design products across a diverse range of end-markets.

Our primary manufacturing product lines currently include Injection Molding, CNC Machining, 3D Printing and Sheet Metal. We continually seek to expand the range of sizes and geometric complexity of the parts we can make with these processes, to extend the variety of materials we are able to support and to identify additional manufacturing processes to which we can apply our technology in order to better serve the evolving preferences and needs of product developers and engineers.

Injection Molding

Our Injection Molding product line uses our 3D CAD-to-CNC machining technology for the automated design and manufacture of molds, which are then used to produce custom plastic and liquid silicone rubber injection-molded parts and over-molded and insert-molded injection-molded parts on commercially available equipment. Our Injection Molding product line works best for on-demand production, bridge tooling, pilot runs and functional prototyping. Our affordable aluminum molds and quick turnaround times help reduce design risk and limit overall production costs for product developers and engineers. Prototype quantities typically range from 25 to 100 parts. Because we retain possession of the molds, customers who need short-run production often come back to Protolabs’ Injection Molding product line for additional quantities. They do so to support pilot production for product testing, while their tooling for high-volume production is being prepared, because they need on-demand manufacturing due to disruptions in their manufacturing process, because their product requires limited annual quantity or because they need end-of-life production support. In 2017, we launched an on-demand manufacturing injection molding product offering. This product offering utilizes our existing processes, but is designed to fulfill the needs of customers with on-going production needs, typically in annual volumes of less than 10,000 parts.

CNC Machining

Our CNC Machining product line uses commercially available CNC machines to offer milling and turning. CNC milling is a manufacturing process that cuts plastic and metal blocks into one or more custom parts based on the 3D CAD model uploaded by the product developer or engineer. CNC turning with live tooling combines both lathe and mill capabilities to machine parts with cylindrical features from metal rod stock. Our efficiencies derive from the automation of the programming of these machines and a proprietary fixturing process.

Quick-turn CNC machining works best for prototyping, form and fit testing, jigs and fixtures and functional components for end-use applications. The CNC Machining product line is well suited to produce small quantities, typically in the range of one to 1,000 parts.

Table of Contents

3D Printing

Our 3D Printing product line includes stereolithography, selective laser sintering, direct metal laser sintering, Multi Jet Fusion, PolyJet and digital light synthesis processes, which offer customers a wide-variety of high-quality, precision rapid prototyping and low-volume production. These processes create parts with a high level of accuracy, detail, strength and durability. Industrial 3D Printing is best suited for functional prototypes, complex designs and end-use applications produced in small quantities, typically in the range of one to several hundred parts.

Sheet Metal

Our Sheet Metal product line includes quick-turn and e-commerce-enabled custom sheet metal parts, which provides customers with prototype and low-volume production parts. The rapid prototype sheet metal process is most often used when form, fit and function are all a priority. Our manufacturing process uses customer 3D CAD models uploaded by the product developer or engineer to fabricate quick-turn prototype sheet metal or short-run production parts. The Sheet Metal product line is well suited to produce quantities in the range of one to 500 parts.

Key Financial Measures and Trends

Revenue

Our operations are comprised of three geographic operating segments in the United States, Europe and Japan. Revenue is derived from our Injection Molding, CNC Machining, 3D Printing and Sheet Metal product lines. Injection Molding revenue consists of sales of custom injection molds and injection-molded parts. CNC Machining revenue consists of sales of CNC-machined custom parts. 3D Printing revenue consists of sales of 3D-printed parts. Sheet Metal revenue consists of sales of fabricated sheet metal custom parts. Our historical and current efforts to increase revenue have been directed at expanding the breadth of our product offerings, gaining new customers and selling to our existing customer base by increasing marketing and selling activities, including:

	●	expanding the breadth and scope of each of our product lines by adding more sizes and materials to our offerings;

	●	the introduction of our 3D Printing product line through our acquisition of FineLine in 2014;

	●	expanding 3D Printing to Europe through our acquisition of Alphaform in October 2015;

	●	the introduction of our Sheet Metal product line through our acquisition of Rapid Manufacturing Group, LLC (RAPID) in 2017; and

	●	continuously improving the usability of our product lines such as our web-centric applications.

During the three months ended June 30, 2020, we served 17,037 unique product developers and engineers who purchase our products through our web-based customer interface, a decrease of 18.2% over the same period in 2019. During the six months ended June 30, 2020, we served 29,703 unique product developers and engineers who purchase our products through our web-based customer interface, a decrease of 5.9% over the same period in 2019. The economic uncertainty arising from the COVID-19 pandemic has impacted the number of product developers and engineers who purchase our products. While we expect the number of product developers and engineers served to grow in the long-term, challenges posed by the COVID-19 pandemic on the global economy have continued through the date of this report. Steps taken by national and local governments to slow the spread of the virus, including business shutdowns and shelter in place orders, have hindered the ability and willingness of project developers and engineers to proceed with development and commercialization projects on the same scale as they have historically. At this time, it is difficult to predict the future given the current economic uncertainty and evolving market conditions.

Cost of Revenue, Gross Profit and Gross Margin

Cost of revenue consists primarily of raw materials, equipment depreciation, employee compensation, benefits, stock-based compensation, facilities costs and overhead allocations associated with the manufacturing process for molds and custom parts. We expect our personnel-related costs to increase in order to retain and attract top talent and remain competitive in the market. Overall, we expect cost of revenue to increase in absolute dollars, but remain relatively constant as a percentage of total revenue.

We define gross profit as our revenue less our cost of revenue, and we define gross margin as gross profit expressed as a percentage of revenue. Our gross profit and gross margin are affected by many factors, including our mix of revenue by product line, pricing, sales volume, manufacturing costs, the costs associated with increasing production capacity, the mix between domestic and foreign revenue sources and foreign exchange rates.

Table of Contents

Operating Expenses

Operating expenses consist of marketing and sales, research and development and general and administrative expenses. Personnel-related costs are the most significant component in each of these categories.

Our recent decrease in operating expenses is mainly due to cost saving measures implemented as a result of the COVID-19 pandemic. However, our long-term business strategy is to continue to be a leading online and technology-enabled manufacturer of quick-turn, on-demand injection-molded, CNC-machined, CNC-turned, 3D-printed and sheet metal custom parts for prototyping and low-volume production. In order to achieve our long-term goals and support our revenue growth, we anticipate continued substantial investments in technology and personnel, resulting in increased operating expenses.

Marketing and sales. Marketing and sales expense consists primarily of employee compensation, benefits, commissions, stock-based compensation, marketing programs such as electronic, print and pay-per-click advertising, trade shows and other related overhead. We expect sales and marketing expense to increase in the future as we increase the number of marketing and sales professionals and marketing programs targeted to increase our customer base and grow revenue.

Research and development. Research and development expense consists primarily of personnel and outside service costs related to the development of new processes and product lines, enhancement of existing product lines, development of software for internal use, maintenance of internally developed software, quality assurance and testing. Costs for internal use software are evaluated by project and capitalized where appropriate under ASC 350-40, Intangibles — Goodwill and Other, Internal-Use Software. We expect research and development expense to increase in the future as we seek to enhance our e-commerce interface technology, internal software and supporting business systems, and continue to expand our product lines.

General and administrative. General and administrative expense consists primarily of employee compensation, benefits, stock-based compensation, professional service fees related to accounting, tax and legal and other related overhead. We expect general and administrative expense to increase in the future as we continue to grow and expand as a global organization.

Other Income, net

Other income, net primarily consists of foreign currency-related gains and losses and interest income on cash balances and investments. Our foreign currency-related gains and losses will vary depending upon movements in underlying exchange rates. Our interest income will vary each reporting period depending on our average cash balances during the period, composition of our marketable security portfolio and the current level of interest rates.

Provision for Income Taxes

Provision for income taxes is comprised of federal, state, local and foreign taxes based on pre-tax income. Overall, we expect our effective tax rate for 2020 and beyond will remain consistent based on the current tax laws.

Market Conditions

On March 11, 2020, the World Health Organization declared the outbreak of the novel coronavirus (COVID-19) a pandemic. The full financial impact of COVID-19 is unknown at this time and will depend on the duration of government restrictions, including travel restrictions, quarantines, shelter in place orders and shutdowns and duration of the economic slowdown and nature and timing of a recovery. The Company has been deemed an essential business and all of our global manufacturing operations have remained open. The Company has activated a global, cross-functional response team, which is closely monitoring the situation and implementing additional safety measures to help ensure the well-being of our employees, customers and suppliers, to minimize disruptions and provide for the safe and reliable supply of products to our customers. In accordance with the guidance provided by both the World Health Organization and the U.S. Centers for Disease Control and Prevention, the Company has implemented safe work practices, including social distancing and work from home guidelines.

We are actively monitoring key product availability and continue to stay connected with our customers to understand impacts on their operations. All of these efforts will help us better plan and prepare, so we can continue to be a leading supplier of custom parts. In anticipation of exposure due to an economic slowdown driven by COVID-19, the Company increased its bad debt reserve by $0.9 million as of June 30, 2020.

The Coronavirus Aid, Relief, and Economic Security (CARES) Act was signed into law on March 27, 2020. The CARES Act is meant to infuse companies with various income and payroll tax cash benefits to ease the impact of the pandemic. A technical correction to the Tax Cuts and Jobs Act of 2017 was included in the CARES Act allowing qualified improvement property to claim bonus depreciation for respective assets placed in service in 2018 and 2019. The impact of the CARES Act to the Company was a $2.6 million reduction in our income taxes payable and a corresponding increase to our deferred tax liability. In addition, the Company has elected to defer deposits of the employer portion of the Social Security tax for the quarter ended June 30, 2020 through the quarter ended December 31, 2020. The Social Security taxes are being accrued for and will be paid beginning in 2021.

See "Risk Factors" in Item 1A of this Quarterly Report on Form 10-Q for further information of the possible impact of the COVID-19 pandemic on our business.

Comparison of Three Months Ended June 30, 2020 and 2019

Revenue

Revenue by reportable segment and the related changes for the three months ended June 30, 2020 and 2019 were as follows:

Total revenue	$	106,575		100.0	%	$	115,932		100.0	%	$	(9,357	)		(8.1	)%

Our revenue decreased $9.4 million, or 8.1%, for the three months ended June 30, 2020 compared to the same period in 2019. By reportable segment, revenue in the United States decreased $4.3 million, or 4.7%, for the three months ended June 30, 2020 compared to the same period in 2019. Revenue in Europe decreased $4.2 million, or 20.1%, and revenue in Japan decreased $0.8 million, or 21.3%, in each case for the three months ended June 30, 2020 compared to the same period in 2019. Our revenue in Europe was impacted by foreign currency exchange rates. Excluding the $0.4 million impact of the changes in foreign currency exchange rates, the decrease in Europe revenue would have been 18.1%. In addition, our revenue in each region was impacted by a decline in order activity driven by current economic conditions as a result of the COVID-19 pandemic.

Our revenue decline during the three months ended June 30, 2020 was the result of a decrease in the volume of product developers and engineers we served. During the three months ended June 30, 2020, we served 17,037 unique product developers and engineers, a decrease of 18.2% over the same period in 2019. The economic uncertainty arising from the COVID-19 pandemic has impacted the number of product developers and engineers who purchase our products. While we expect the number of product developers and engineers served to grow in the long-term, challenges posed by the COVID-19 pandemic on the global economy have continued through the date of this report. Steps taken by national and local governments to slow the spread of the virus, including business shutdowns and shelter in place orders, have hindered the ability and willingness of project developers and engineers to proceed with development and commercialization projects on the same scale as they have historically. At this time, it is difficult to predict the future given the current economic uncertainty and evolving market conditions.

Our revenue decreases were primarily driven by a decline in order activity as a result of the economic uncertainty created by the COVID-19 pandemic. International revenue was negatively impacted by $0.4 million during the three months ended June 30, 2020 compared to the same period in 2019 as a result of foreign currency movements, primarily the weakening of the British Pound and Euro relative to the United States Dollar.

Revenue by product line and the related changes for the three months ended June 30, 2020 and 2019 were as follows:

	Three Months Ended June 30,
	2020					2019					Change
(dollars in thousands)	$		% of Total Revenue			$		% of Total Revenue			$			%
Revenue
Injection Molding	$	57,894		54.3	%	$	55,457		47.8	%	$	2,437			4.4	%

Total revenue	$	106,575		100.0	%	$	115,932		100.0	%	$	(9,357	)		(8.1	)%

By product line, our revenue decrease was driven by a 26.0% decrease in CNC Machining revenue, a 6.7% decrease in 3D Printing revenue, and a 14.7% decrease in Sheet Metal revenue, which was partially offset by a 4.4% increase in Injection Molding revenue and a 19.7% increase in Other Revenue, in each case for the three months ended June 30, 2020 compared to the same period in 2019.

Cost of Revenue, Gross Profit and Gross Margin

Cost of Revenue. Cost of revenue decreased $1.6 million, or 2.8%, for the three months ended June 30, 2020 compared to the same period in 2019, which was less than the rate of revenue decrease of 8.1% for the three months ended June 30, 2020 compared to the same period in 2019. The decrease in cost of revenue was primarily driven by lower revenue volumes and cost saving measures implemented as a result of the COVID-19 pandemic. Specifically, the decreases were driven by a decrease in direct labor headcount and hours worked resulting in personnel and related cost decreases of $1.5 million and raw material and production cost decreases of $0.6 million, which were partially offset by equipment and facility-related cost increases of $0.5 million to support future growth of the business.

Gross Profit and Gross Margin. Gross profit decreased from $60.2 million in the three months ended June 30, 2019 to $52.5 million in the three months ended June 30, 2020. Gross margin decreased from 52.0% in the three months ended June 30, 2019 to 49.2% in the three months ended June 30, 2020 primarily due to the fixed cost structure of our facilities and equipment supporting lower revenue this quarter and the timing and mix of revenue.

Operating Expenses, Other Income, net and Provision for Income Taxes

Marketing and Sales. Marketing and sales expenses decreased $2.3 million, or 12.2%, during the three months ended June 30, 2020 compared to the same period in 2019 due primarily to personnel and related cost decreases of $1.0 million as well as marketing program cost decreases of $1.3 million.

Research and Development. Our research and development expenses increased $0.5 million, or 5.9%, during the three months ended June 30, 2020 compared to the same period in 2019 due to an increase in headcount resulting in personnel and related cost increases of $0.5 million.

General and Administrative. Our general and administrative expenses decreased $0.7 million, or 5.2%, during the three months ended June 30, 2020 compared to the same period in 2019 due to administrative cost decreases of $0.5 million, amortization cost decreases of $0.1 million and stock-based compensation cost decreases of $0.2 million, which were partially offset by professional service cost increases of $0.1 million.

Other Income, net. We recognized other income, net of $0.8 million for the three months ended June 30, 2020, a decrease of $0.4 million compared to other income, net of $1.1 million for the three months ended June 30, 2019. Other income, net for the three months ended June 30, 2020 primarily consisted of $0.4 million in interest income on investments and a $0.3 million gain on foreign currency. Other income, net for the three months ended June 30, 2019 primarily consisted of $0.5 million in interest income on investments and a $0.5 million gain on foreign currency.

Provision for Income Taxes. Our effective tax rate of 16.6% for the three months ended June 30, 2020 decreased 5.3% compared to 21.9% for the same period in 2019. The decrease in the effective tax rate is primarily due to an increase in tax benefits from the vesting of restricted stock and the exercise of stock options and an increase in the research and development tax credit. Our income tax provision of $2.5 million for the three months ended June 30, 2020 decreased $2.0 million compared to our income tax provision of $4.5 million for the three months ended June 30, 2019.

By reportable segment, revenue in the United States decreased $2.1 million, or 1.2%, for the six months ended June 30, 2020 compared to the same period in 2019. Revenue in Europe decreased $4.7 million, or 11.1%, and revenue in Japan decreased $1.0 million, or 11.7%, in each case for the six months ended June 30, 2020 compared to the same period in 2019. Our revenue in Europe was impacted by foreign currency exchange rates. Excluding the $1.1 million impact of the changes in foreign currency exchange rates, the decrease in Europe revenue would have been 8.6%. In addition, our revenue in each region was impacted by a decline in order activity driven by current economic conditions as a result of the COVID-19 pandemic.

Our revenue decline during the six months ended June 30, 2020 was the result of a decrease in the volume of product developers and engineers we served. During the six months ended June 30, 2020, we served 29,703 unique product developers and engineers, a decrease of 5.9% over the same period in 2019. The economic uncertainty arising from the COVID-19 pandemic has impacted the number of product developers and engineers who purchase our products. While we expect the number of product developers and engineers served to grow in the long-term, challenges posed by the COVID-19 pandemic on the global economy have continued through the date of this report.

Our revenue decreases were primarily driven by a decline in order activity as a result of the economic uncertainty created by the COVID-19 pandemic. International revenue was negatively impacted by $0.9 million during the six months ended June 30, 2020 compared to the same period in 2019 as a result of foreign currency movements, primarily the weakening of the British Pound and Euro relative to the United States Dollar.

Cost of Revenue, Gross Profit and Gross Margin

Cost of Revenue. Cost of revenue increased $0.8 million, or 0.8%, for the six months ended June 30, 2020 compared to the same period in 2019, despite the rate of revenue decrease of 3.4% for the six months ended June 30, 2020 compared to the same period in 2019. The increases were driven by a $1.6 million increase in equipment and facility-related costs to support future growth of the business, which was partially offset by personnel and related cost decreases of $0.8 million.

Gross Profit and Gross Margin. Gross profit decreased from $119.1 million in the six months ended June 30, 2019 to $110.6 million in the six months ended June 30, 2020 primarily due to a decrease in revenue. Gross margin decreased from 51.9% in the six months ended June 30, 2019 to 49.9% in the six months ended June 30, 2020 due to the fixed cost structure of our facilities and equipment supporting lower revenue this year and the timing and mix of revenue.

Operating Expenses, Other Income, net and Provision for Income Taxes

Marketing and Sales. Marketing and sales expenses decreased $2.7 million, or 7.3%, during the six months ended June 30, 2020 compared to the same period in 2019 due primarily to personnel and related cost decreases of $1.2 million as well as marketing program cost decreases of $1.5 million.

Research and Development. Our research and development expenses increased $1.5 million, or 9.0%, during the six months ended June 30, 2020 compared to the same period in 2019 due to an increase in headcount resulting in personnel and related cost increases of $1.4 million and operating cost increases of $0.1 million.

General and Administrative. Our general and administrative expenses increased $0.6 million, or 2.3%, during the six months ended June 30, 2020 compared to the same period in 2019 due to personnel and related cost increases of $1.2 million and professional services increases of $0.2 million, which were partially offset by stock-based compensation decreases of $0.5 million, as well as a $0.3 million decrease in amortization cost.

Other Income, net. We recognized other income, net of $1.8 million for the six months ended June 30, 2020, an increase of $0.5 million compared to other income, net of $1.3 million for the six months ended June 30, 2019. Other income, net for the six months ended June 30, 2020 primarily consisted of $0.9 million in interest income on investments and a $0.9 million gain on foreign currency. Other income, net for the six months ended June 30, 2019 primarily consisted of $1.1 million in interest income on investments and a $0.1 million gain on foreign currency.

Provision for Income Taxes. Our effective tax rate of 19.4% for the six months ended June 30, 2020 decreased 2.1% compared to 21.5% for the same period in 2019. The decrease in the effective tax rate is primarily due to an increase in tax benefits from the vesting of restricted stock and the exercise of stock options and an increase in the research and development tax credit. Our income tax provision of $6.4 million for the six months ended June 30, 2020 decreased $2.3 million compared to our income tax provision of $8.7 million for the six months ended June 30, 2019.

Sources of Liquidity

Historically, we have primarily financed our operations and capital expenditures through cash flow from operations. We had cash and cash equivalents of $98.0 million as of June 30, 2020, a decrease of $27.2 million from December 31, 2019. The decrease in our cash was primarily due to cash used in investing activity including net investments in marketable securities of $29.0 million and purchases of property, equipment and other capital assets of $33.3 million and repurchases of common stock of $14.7 million, which were partially offset by cash generated through operations of $53.4 million.

Cash Flows from Operating Activities

Cash flows from operating activities were $53.4 million during the six months ended June 30, 2020 and primarily consisted of net income of $26.6 million, adjusted for certain non-cash items, including depreciation and amortization of $15.9 million, stock-based compensation expense of $6.7 million and deferred taxes of $5.7 million, which were partially offset by changes in operating assets and liabilities and other items totaling $1.5 million. Cash flows from operating activities were $54.9 million during the six months ended June 30, 2019 and primarily consisted of net income of $31.7 million, adjusted for certain non-cash items, including depreciation and amortization of $15.0 million, stock-based compensation expense of $6.5 million, deferred taxes of $1.6 million and changes in operating assets and liabilities and other items totaling $0.1 million.

Cash flows from operating activities decreased $1.5 million during the six months ended June 30, 2020 compared to the same period in 2019, primarily due to decreases in net income of $5.1 million, decreases in changes in operating assets and liabilities of $1.0 million driven by timing of cash receipts and payments, and decreases of $0.4 million in other items, which were partially offset by increases in deferred taxes of $4.1 million and increases in depreciation and amortization of $0.9 million.

Cash Flows from Investing Activities

Cash used in investing activities was $65.3 million during the six months ended June 30, 2020, consisting of $29.0 million in net investments in marketable securities, $33.3 million for the purchases of property, equipment and other capital assets and $3.0 million for purchases of other assets and investments.

Cash used in financing activities was $15.2 million during the six months ended June 30, 2020, consisting of $14.7 million in repurchases of common stock and $3.4 million in purchases of shares withheld for tax obligations associated with equity transactions, which were partially offset by $2.9 million in proceeds from the exercise of stock options.

Cash used in financing activities was $21.6 million during the six months ended June 30, 2019, consisting of $21.4 million in repurchases of common stock and $2.4 million in purchases of shares withheld for tax obligations associated with equity transactions, which were partially offset by $2.2 million in proceeds from the exercise of stock options.

Off-Balance Sheet Arrangements

Item 3. Quantitative and Qualitative Disclosures about Market Risk

Foreign Currency Risk

As a result of our foreign operations, we have revenue, expenses, assets and liabilities that are denominated in foreign currencies. We generate revenue and incur production costs and operating expenses in British Pounds, Euros and Japanese Yen.

Our operating results and cash flows are adversely impacted when the United States Dollar appreciates relative to foreign currencies. Additionally, our operating results and cash flows are adversely impacted when the British Pound appreciates relative to the Euro. As we expand internationally, our results of operations and cash flows will become increasingly subject to changes in foreign currency exchange rates.

We have not used forward contracts or currency borrowings to hedge our exposure to foreign currency risk. Foreign currency risk can be assessed by estimating the change in results of operations or financial position resulting from a hypothetical 10% adverse change in foreign exchange rates. We believe such a change would generally not have a material impact on our financial position, but could have a material impact on our results of operations. We recognized foreign currency gains of $0.3 million and $0.9 million during the three and six months ended June 30, 2020, respectively. We recognized foreign currency gains of $0.5 million and $0.1 million during the three and six months ended June 30, 2019, respectively. The changes in foreign exchange rates had a negative impact on consolidated revenue of $0.4 million for the three months ended June 30, 2020 and $0.9 million for the six months ended June 30, 2020 as compared to the same periods in 2019.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934 (Exchange Act)) as of the end of the period covered by this report. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of the period covered by this quarterly report, our disclosure controls and procedures are effective and 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 accurately and within the time frames specified in the SEC’s rules and forms and 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 have been no changes in our internal control over financial reporting (as such term is defined in Rule 13a-15(f) under the Exchange Act) during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

From time to time, we are subject to various legal proceedings and claims that arise in the ordinary course of our business activities. Although the results of litigation and claims cannot be predicted with certainty, as of the date of these financial statements, we do not believe we are party to any litigation the outcome of which, if determined adversely to us, would individually or in the aggregate be reasonably expected to have a material adverse effect on our business.

Item 1A. Risk Factors

Part I, Item 1A. “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2019 includes a discussion of our risk factors. The information presented below updates, and should be read in conjunction with, the risk factors and information disclosed in our Form 10-K. Except as presented below, there have been no material changes from the risk factors described in our Form 10-K.

Economic uncertainty arising from the recent COVID-19 pandemic could adversely affect our business and results of operations.

On March 11, 2020, the World Health Organization declared the outbreak of the novel coronavirus (COVID-19) a pandemic. The COVID-19 outbreak and associated counter-acting measures implemented by governments around the world, as well as increased business uncertainty, could adversely affect our business and results of operations. At this time, the Company is monitoring the global outbreak of the COVID-19 and is taking steps to mitigate the risks to our employees, customers, suppliers and other stakeholders. The Company has been deemed an essential business and all of our global manufacturing operations have remained open. The current business environment and quickly evolving market conditions require significant management judgment to interpret and quantify the potential impact on our assumptions about future financial performance and operating cash flows. To the extent that changes in the current business environment impact our ability to achieve levels of forecasted operating results and cash flows, if our stock price were to trade below book value per share for an extended period of time and/or should other events occur indicating the carrying value of our assets might be impaired, we may be required to recognize impairment losses on goodwill, intangible and tangible assets.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds

On February 9, 2017, we announced that our board of directors had authorized the repurchase of shares of our common stock from time to time on the open market or in privately negotiated purchases, at an aggregate purchase price of up to $50 million. On May 16, 2019, we announced that our board of directors approved a $50 million increase in its authorized stock repurchase program and extended the term of the program through December 31, 2023. This authorization increases the stock repurchase program to $100 million.

The timing and amount of any share repurchases will be determined by our management based on market conditions and other factors.

The common stock repurchase does not obligate us to repurchase any dollar amount or number of shares. During the three months ended June 30, 2020, we repurchased 38,154 shares of our common stock at a total purchase price of $2.7 million under this program. Common stock repurchase activity through June 30, 2020 was as follows:

Period	Total Number of Shares Purchased		Average Price Paid per Share		Total Number of Shares Purchased as Part of Publicly Announced Plans or Programs		Maximum Dollar Value of Shares that May Yet Be Purchased Under the Plans or Programs (in thousands) (1)
April 1, 2020 through April 30, 2020		38,154	$	70.81		38,154	$	35,175
May 1, 2020 through May 31, 2020		-	$	-		-	$	35,175

		38,154	$	70.81		38,154	$	35,175

(1) Effective May 15, 2019 the Board of Directors authorized the repurchase of shares of the Company’s common stock from time to time on the open market or in privately negotiated purchases, at an aggregate purchase price of up to $100 million.
