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, 2025, as filed with the Securities and Exchange Commission (SEC) on February 20, 2026.

The accompanying Consolidated Balance Sheet as of December 31, 2025 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 thereto included in the Company's Annual Report on Form 10-K filed on February 20, 2026 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.

Apart from the items discussed in our Annual Report on Form 10-K for the year ended December 31, 2025, there are no other new accounting pronouncements that are expected to have a significant impact on the Company’s Consolidated Financial Statements or related disclosures.

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 106,341 and 214,801 for the three months ended September 30, 2026 and 2025, respectively, and 50,464 and 380,740 for the nine months ended September 30, 2026 and 2025, respectively.

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

Note 4 –Goodwill and Other Intangible Assets

There wereno changes in the carrying amount of goodwill during the three and nine months ended September 30, 2026.

Intangible assets other than goodwill at September 30, 2026 and December 31, 2025 were as follows:

Intangible assets allocated to the Protolabs Network entities consisted of intangible assets of €11.6 million in Europe and $16.6 million in the United States as of the date of the acquisition. The Euro-denominated intangible assets are translated at the end of each period using the current exchange rates resulting in a foreign currency translation adjustment that is recorded as a component of other comprehensive (loss) income. Foreign currency unrealized losses related to intangible assets were $1.0 million and $0.5 million as of September 30, 2026 and December 31, 2025, respectively. Amortization expense for intangible assets was $0.9 million for each of the three months ended September 30, 2026 and 2025, and $2.7 million and $2.8 million for the nine months ended September 30, 2026 and 2025, respectively.

Estimated aggregate amortization expense based on the current carrying value of the amortizable intangible assets and current exchange rates is as follows:

Note 5 –Fair Value Measurements and Marketable Securities

Accounting Standards Codification, 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 arenot 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 financial assets measured at fair value on a recurring basis consist primarily of cash equivalents and marketable securities. The Company’s cash equivalents consist primarily of money market mutual funds that are valued using Level 1 inputs. The Company's marketable securities consist of 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 the Company's financial assets measured at fair value on a recurring basis as of September 30, 2026 and December 31, 2025:

The Company's marketable securities are classified as available-for-sale and recorded at fair value.

The following table summarizes the amortized cost, unrealized gains (losses), and fair value of the Company’s marketable securities as of September 30, 2026 and December 31, 2025:

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 September 30, 2026 balance of available-for-sale debt securities by contractual maturity is shown in the following table at fair value. Actual maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

Note 6 –Inventory

Inventory consists primarily of raw materials, which are recorded at the lower of cost and net realizable value using the standard cost method, which approximates first-in, first-out (FIFO) cost. The Company periodically reviews its inventory for slow-moving, damaged and discontinued items and provides allowances to reduce such items identified to their recoverable amounts.

The Company’s inventory consisted of the following as of the dates indicated:

Note 7 –Stock-Based Compensation

The Proto Labs, Inc. 2022 Long-Term Incentive Plan (as amended, the 2022 Plan) was originally approved by the Company's shareholders on August 29, 2022, and subsequently amended and restated on May 23, 2024. The term of the 2022 Plan runs forten years from the date of the shareholder approval. On May 20, 2025 and May 19, 2026, the Company's shareholders approved additional amendments to the 2022 Plan to increase the number of shares available for issuance pursuant to awards under the 2022 Plan by an additional 296,000 shares and 395,000 shares, respectively. 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 often years from the date of grant. The compensation and talent 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 and talent 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.

The Company also has outstanding awards under the 2012 Long-Term Incentive Plan, as amended (the 2012 Plan), although the plan expired in February 2022 and no additional awards have since been or will be made under the 2012 Plan. The 2012 Plan provided the Company the ability to grant stock options, SARs, restricted stock, restricted stock units, other stock-based awards and cash incentive awards. Awards under the 2012 Plan that subsequently expired, were forfeited or cancelled, or settled in cash after August 29, 2022 became available for awards under the 2022 Plan.

In addition, the Company has outstanding awards that were not granted under the 2022 Plan or the 2012 Plan. These awards were granted as inducement awards to the Company’s Chief Executive Officer in May 2025.

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 forsix-month offering periods, each with a single purchase period ending on May 15 or November 15, as applicable. 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 $3.4 million and $3.7 million for the three months ended September 30, 2026 and 2025, respectively, and $10.7 million and $11.9 million for the nine months ended September 30, 2026 and 2025, respectively.

Stock Options

The following table summarizes stock option activity during the nine months ended September 30, 2026:

The outstanding options generally have a term often years. For employees, options granted become exercisable ratably over the vesting period, which is generally a period offour years, beginning on the first anniversary of the grant date, subject to the employee’s continuing service to the Company.

The weighted-average grant date fair value of options that were granted during the nine months ended September 30, 2026 was $35.95.

The following table provides the assumptions used in the Black-Scholes pricing model valuation of options during the nine months ended September 30, 2026 and 2025:

As of September 30, 2026, there was $3.7 million of unrecognized compensation expense related to non-vested stock options, which is expected to be recognized over a weighted-average period of 3.0 years.

Restricted Stock Units

Restricted stock unit (RSU) awards are share-settled awards and restrictions lapse ratably over the vesting period, which is generally a period offour years, beginning on the first anniversary of the grant date, subject to the employee's continuing service to the Company. For the board of directors, restrictions generally lapse in full on the first anniversary of the grant date.

The following table summarizes RSU activity during the nine months ended September 30, 2026:

As of September 30, 2026, there was $17.3 million of unrecognized compensation expense related to non-vested RSU, which is expected to be recognized over a weighted-average period of 2.8 years.

Performance Stock Units

Performance stock units (PSUs) are expressed in terms of a target number of PSUs, with anywhere between 0 percent and 200 percent of that target number capable of being earned and vesting at the end of athree-year performance period depending on the Company’s three-year cumulative total shareholder return performance relative to an index and the award recipient’s continued employment. The Company’s PSUs are based on market conditions and the related compensation cost is based on the fair value at grant date calculated using a Monte Carlo pricing model.

The following table summarizes PSU activity during the nine months ended September 30, 2026:

The following table provides the assumptions used in the Monte Carlo pricing model valuation of PSUs during the nine months ended September 30, 2026 and 2025:

As of September 30, 2026, there was $8.8 million of unrecognized compensation expense related to non-vested PSU, which is expected to be recognized over a weighted-average period of 2.0 years.

Employee Stock Purchase Plan

The following table presents the assumptions used to estimate the fair value of the ESPP during the nine months ended September 30, 2026 and 2025:

Note 8 –Accumulated Other Comprehensive (Loss) Income

Other comprehensive (loss) income is comprised of foreign currency translation adjustments and net unrealized (losses) gains on investments in securities.

The following table presents the changes in accumulated other comprehensive (loss) income balances during the three and nine months ended September 30, 2026 and 2025:

Note 9 –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, 2026 and 2025, the Company recorded an income tax provision of $4.4 million and $3.0 million, respectively. For the nine months ended September 30, 2026 and 2025, the Company recorded an income tax provision of $11.1 million and $7.7 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 September 30, 2026 was 27.4 percent compared to 29.6 percent in the same period of the prior year. The effective tax rate decreased by 2.2 percent for the three months ended September 30, 2026 when compared to the same period in 2025, primarily due to an operating rate catch-up credit driven by strong pre-tax income and an offset by reduced excess tax benefits on stock-based compensation. The effective income tax rate for the nine months ended September 30, 2026 was 27.7 percent compared to 33.5 percent in the same period of the prior year. The effective tax rate decreased by 5.8 percent for the nine months ended September 30, 2026 when compared to the same period in 2025, primarily due to a favorable shift in the geographic mix of pre-tax income toward lower-tax jurisdictions and strong domestic pre-tax income.

The effective income tax rate for the three and nine months ended September 30, 2026 differs from the U.S. federal statutory rate of 21.0 percent due to various factors, including operating in multiple state and foreign jurisdictions partially offset by tax credits for which the Company qualifies.

The Company had unrecognized tax benefits totaling $3.2 million and $3.1 million as of September 30, 2026 and December 31, 2025, 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 10 –Segment Reporting

The Company’s reportable segments are based on the internal reporting used by the Company’s Chief Executive Officer (CEO), who is the chief operating decision maker (CODM), to assess operating performance and make decisions about the allocation of resources. The CODM's primary profit measure for purposes of resource allocation and performance assessment is income (loss) from operations at the segment level. This measure is used to evaluate current-period performance, develop forecasts and budgets, and make decisions about capital and other resource allocations between segments. The Company’s reportable segments are based upon geographic region, consisting of the United States and Europe. The Corporate Unallocated 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.

Revenue in the United States and Europe is derived primarily from 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 and lathe-turned custom parts. 3D Printing revenue consists of sales of 3D-printed parts. Sheet Metal revenue consists of sales of fabricated sheet metal parts.

Intercompany transactions primarily relate to intercontinental activity and have been eliminated and are excluded from the reported amounts. The difference between income (loss) 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 reportable segments.

The following table summarizes selected financial information by reportable segments:

1 Segment expenses consist primarily of raw materials, equipment depreciation, employee compensation including benefits, commissions and stock-based compensation, facilities costs and overhead allocations associated with the manufacturing process for molds and custom parts, marketing programs such as electronic, print and pay-per-click advertising and trade shows and other related costs for our United States and Europe reportable segments. Segment expenses for our Corporate Unallocated category consist primarily of personnel and outside service costs related to the development of new processes and product lines, enhancements of existing product lines, software developed for internal use, maintenance of internally developed software, quality assurance and testing, employee compensation including benefits and stock-based compensation, severance, professional service fees related to accounting, tax and legal, and other related overhead costs.

Total long-lived assets, expenditures for additions to long-lived assets, and depreciation and amortization expense were as follows:

Revenue by product line for the three and nine months ended September 30, 2026 and 2025 was as follows:
