Notes to Consolidated Financial Statements
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, 2022, as filed with the Securities and Exchange Commission (SEC) on February 21, 2023 .
The accompanying Consolidated Balance Sheet as of December 31, 2022 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 Quarterly Report on Form 10-Q should be read in conjunction with the Company’s Consolidated Financial Statements and Notes included in the Company's Annual Report on Form 10-K filed on February 21, 2023 as referenced above.
Note 2 – Recent Accounting Pronouncements
The Company did not recently adopt any accounting pronouncements that had a material impact on the Company's Consolidated Financial Statements. There are no pending accounting pronouncements that are expected to have a material impact on the Company's 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 and other stock-based 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. Anti-dilutive options were excluded from the calculation of diluted weighted average shares outstanding and were 393,592 and 210,443 for the three months ended September 30, 2023 and 2022 , respectively, and 372,353 and 202,901 for the nine months ended September 30, 2023 and 2022, respectively.

Note 5 – Fair Value Measurements
Accounting Standards Codification, Fair Value Measuremen t (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 assets and liabilities that are required to be measured or disclosed at fair value on a recurring basis include cash and cash equivalents and marketable securities. The Company’s cash consists of bank deposits and cash equivalents consist primarily of money market mutual funds. The Company determines the fair value of these investments using Level 1 inputs. The Company's marketable securities consist of short-term and long-term agency, municipal, corporate and other debt securities. Fair value for the corporate debt securities is 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).
The following table summarizes financial assets as of September 30, 2023 and December 31, 2022 measured at fair value on a recurring basis:

Note 8 – Stock-Based Compensation
Under the Company’s 2012 Long-Term Incentive Plan, as amended (the 2012 Plan), the Company had the ability to grant stock options, stock appreciation rights (SARs), restricted stock, restricted stock units, other stock-based awards and cash incentive awards through February 23, 2022 . On July 8, 2022 , the board of directors approved the Proto Labs, Inc. 2022 Long-Term Incentive Plan (the 2022 Plan), which was approved by the Company's shareholders at a Special Meeting of Shareholders on August 29, 2022 . No awards were granted from February 23, 2022 to August 29, 2022 . Awards outstanding under the 2012 Plan as of August 29, 2022 will continue to be subject to the terms of the 2012 Plan, but if those awards subsequently expire, are forfeited or cancelled or are settled in cash, the shares subject to those awards will become available for awards under the 2022 Plan. Under the 2022 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 2022 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 2022 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 $ 4.4 million and $ 4.9 million for the three months ended September 30, 2023 and 2022, respectively, and $ 11.8 million and $ 13.3 million for the nine months ended September 30, 2023 and 2022.

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 September 30, 2023 and 2022, the Company recorded an income tax provision of $ 2.8 million and $ 2.1 million, respectively. For the nine months ended September 30, 2023 and 2022, the Company recorded an income tax provision of $ 7.8 million and $ 7.2 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 September 30, 2023 was 25.9 percent compared to 34.5 percent in the same period of the prior year. The effective tax rate decreased by 8.6 percent for the three months ended September 30, 2023 when compared to the same period in 2022, primarily due to a decrease in losses in jurisdictions that are not eligible for tax benefits due to valuation allowances. Th e effective income tax rate for the nine months ended September 30, 2023 was 43.2 percent compared to 38.4 percent in the same period of the prior year. The effective tax rate increased by 4.8 percent for the nine months ended September 30, 2023 when compared to the same period in 2022, primarily due to the tax impact of the foreign currency translation loss from the substantial completion on the closure of our Japan business.
The effective income tax rate for the three and nine months ended September 30, 2023 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 $ 3.9 million as of September 30, 2023 and $ 3.2 million as of December 31, 2022, respectively, that if recognized would result in a reduction of the Company’s effective tax rate. The liabilities are classified as other long-term liabilities in the accompanying consolidated balance sheets. 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.

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 nine months ended September 30, 2023 and 2022 were as follows:

Overview
We are one of the world’s largest and fastest digital manufacturers of custom prototypes and on-demand production parts. Our mission is to empower companies to bring new ideas to market by offering the fastest and most comprehensive digital manufacturing service in the world. Our automated quoting and manufacturing systems allow us to produce commercial-grade plastic, metal, and liquid silicone rubber parts in as fast as one day. We manufacture prototype 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. For most of our offerings, 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. In addition, we serve procurement and supply chain professionals seeking to manufacture custom parts on-demand. Through the acquisition of Hubs (formerly 3D Hubs, Inc.) (Hubs) in 2021, we are able to provide our customers access to a global network of premium manufacturing partners who reside across North America, Europe and Asia, complementing our in-house manufacturing. We believe our use of advanced technology enables us to offer significant advantages at competitive prices to many customers and is the primary reason we have become a leading supplier of custom parts.
On May 27, 2022, our board of directors approved a plan for the closure of our manufacturing facility in Japan and announced an intention to cease operations in the region. Affected employees in Japan received severance and other transition assistance that meet or exceed local requirements. We expect to complete the closure plan within the year.
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. In 2021, we augmented our internal manufacturing operations through our acquisition of Hubs to expand the envelope of custom parts we can provide to our customers through a network of premium manufacturing partners in each of our product lines.
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 molds and quick turnaround times help reduce design risk and limit overall production costs for product developers and engineers. Because we retain possession of the molds, customers who need short-run production often come back to Proto
17
Labs’ 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 service. This service utilizes our existing processes, but is designed to fulfill the needs of customers with on-going production needs.
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 customer. CNC turning is a subtractive manufacturing process that rotates a metal rod while a cutting tool is used to remove material and create final parts. Quick-turn CNC machining works best for prototyping, form and fit testing, jigs and fixtures and functional components for end-use applications.
Industrial 3D Printing
Our Industrial 3D Printing product line includes SL, SLS, DMLS, MJF, PolyJet, Carbon DLS and fused deposition modeling (FDM) processes, which offers 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.
Sheet Metal
Our Sheet Metal product line includes quick-turn and e-commerce-enabled custom sheet metal parts, providing 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 customer to fabricate rapid prototyping sheet metal or end-use production parts and assemblies.
Key Financial Measures and Trends
Revenue
Our operations are comprised of three geographic operating segments in the United States, Europe and Japan. On May 27, 2022, our board of directors approved a plan for the closure of our manufacturing facility in Japan and announced an intention to cease operations in the region. 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 gaining new customers and selling to our existing customer base by increasing marketing and selling activities, including:
• expanding the breadth and scope of our products by adding more sizes and materials to our offerings;

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 customer 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.
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, the mix between revenue produced in our internal manufacturing operations and outsourced to our external manufacturing partners, the mix between premium expedited manufacturing and longer lead times, and foreign currency exchange rates.
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 business strategy is to continue to be a leading online and technology-enabled manufacturer of quick-turn, on-demand injection-molded, CNC-machined, 3D-printed and sheet metal custom parts for prototyping and low-volume production. In order to achieve our goals, we anticipate continued substantial investments in technology and personnel, resulting in increased operating expenses in the future.
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, which includes an allocation of information technology expense including amortization of Protolabs 2.0 software assets. 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, which includes an allocation of information technology expense including amortization of Protolabs 2.0 software assets. We expect general and administrative expense to increase in the future as we continue to grow and expand as a global organization.
Closure of Japan business. Closure of Japan business expense is driven by our decision to close the Japan manufacturing facility and exit the Japan market. The expenses consist primarily of operating expense, including employee severance, write-down of fixed assets, facility-related charges and goodwill impairment charges.
Other Income (Loss), net
Other income (loss), 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 foreign currency 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, our effective tax rate for 2023 and beyond may differ from historical effective tax rates due to increases in losses in foreign
19
operations that are not eligible for tax benefits on account of valuation allowances, as well as any future tax law changes that may impact our effective tax rate.

Revenue in Europe increased $5.3 million, or 24.7%, and revenue in Japan decreased $1.3 million, or 100.0% in each case for the three months ended September 30, 2023 compared to the same period in 2022. The decrease in Japan revenue was driven by our decision in the second quarter of 2022 to close our Japan operation s. Revenue generated from our digital network powered by Hubs was $22.6 million and $12.1 million for the three months ended September 30, 2023 and 2022, respectively. International revenue was positively impacted by $1.7 million du ring three months ended September 30, 2023 compared to the same period in 2022 as a result of foreign currency movements, primarily the strengthening of the British Pound and Euro relative to the United States Dollar.
During the three months ended September 30, 2023, we served 23,080 unique product developers and engineers, which is a decrease of 3.1% from the same period in 2022. Our decline in product developers and engineers served decreased at a higher rate than our revenue growth, resulting in an increase in the average spend per product developer and engineer primarily due to a larger portion of the business shifting to larger orders and improvements in average order values in digital network powered by Hubs.
Revenue by product line and the related changes for the three months ended September 30, 2023 and 2022 were as follows:
Three Months Ended September 30,

Total Revenue $ 130,705 100.0 % $ 121,721 100.0 % $ 8,984 7.4 %
By product line, our revenue increase was driven by a 11.4% increase in CNC Machining revenue, a 5.6% increase in Injection Molding revenue and a 9.1% increase in 3D Printing revenue, which was partially offset by a 17.8% decrease in
21
Sheet Metal revenue and a 24.8% decrease in Other Revenue, in each case for the three months ended September 30, 2023 compared to the same period in 2022.
Cost of Revenue, Gross Profit and Gross Margin

Marketing and Sales. Marketing and sales expenses increased $1.1 million, or 5.3%, during the three months ended September 30, 2023 compared to the same period in 2022. The increase in marketing and sales expenses was primarily driven by increases in personnel and related costs of $1.2 million and marketing program cost decreases of $0.1 million during the three months ended September 30, 2023 when compared to the same period in 2022.
Research and Development. Our research and development expenses increased $0.8 million, or 8.6%, during the three months ended September 30, 2023 compared to the same period in 2022 primarily due to increases of $1.1 million in personnel and related costs, which were partially offset by decreases of $0.3 million in professional services and other operating costs.
General and Administrative.

Net increase (decrease) in cash and cash equivalents $ 26,938 $ (6,568)
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 $83.5 million as of September 30, 2023, an increase of $26.9 million from December 31, 2022. The increase in our cash was primarily due to cash provided by operating activities of $56.0 million and proceeds from call redemptions and maturities of marketable securities of $19.1 million, which were partially offset by $9.9 million for purchases of property, equipment and other capital assets, and $39.1 million in repurchases of common stock.
We believe that our existing cash and cash equivalents together with cash generated from operations will be sufficient to meet our working capital and capital expenditure requirements for at least the next 12 months.

Critical Accounting Estimates
We have adopted various accounting policies to prepare the Consolidated Financial Statements in accordance with accounting principles generally accepted in the United States of America (U.S. GAAP). The preparation of these financial statements requires us to make estimates, judgements and assumptions. Our significant accounting policies and estimates are disclosed in Note 2 to the Consolidated Financial Statements included Pat II, Item 8 in our Annual Report on Form 10-K for the year ended December 31, 2022. There were no material changes to our critical accounting policies and estimates during the nine months ended September 30, 2023.

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. During the nine months ended September 30, 2023, we recognized a foreign currency translation loss of $3.9 million in connection with substantially completing our closure of our Japan business. We recognized foreign currency losses of $0.2 million and $0.4 million during the three months ended September 30, 2023 and 2022, respectively. We recognized foreign currency losses of $0.1 million and $0.8 million during the nine months ended September 30, 2023 and 2022, respectively. The changes in foreign exchange rates had a positive impact on consolidated revenue of $1.7 million for the three months ended September 30, 2023 and a negative impact of $1.3 million for the nine months ended September 30, 2023 as compared to the same period in 2022.
