The Company&#x2019;s cash consists of bank deposits. The Company&#x2019;s cash equivalents measured at fair value consist of money market mutual funds. The Company determines the fair value of these investments using Level <em style="font: inherit;">1</em> inputs. The Company's marketable securities consist of&#xa0;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 <em style="font: inherit;">1</em>). 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 <em style="font: inherit;">2</em>).

  <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">In the first quarter of 2021, the Company sold held-to-maturity securities in order to partially fund the acquisition of 3D Hubs. As a result of the sale, all remaining marketable securities were reclassified to available-for-sale securities and reported at fair value.</p>

  <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">The Company recorded a contingent consideration liability at the acquisition date of 3D Hubs representing the amounts payable to former shareholders, as outlined under the terms of the merger agreement, payable subject to the satisfaction of performance-based targets during fiscal year 2021 and fiscal year 2022, consisting of up to $25.0 million in cash and up to 143,983 shares of the Company's common stock valued at $27.8 million on the date of close. The fair value of the contingent consideration (Level 3) is determined using a Monte Carlo pricing model. Subsequent changes in the fair value of the contingent consideration liabilities will be recorded in the Consolidated Statements of Comprehensive Income. Fluctuations due to foreign currency translation will be recorded in the Consolidated Statements of Shareholders&#x2019; Equity.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><b>Overview</b></p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">We are the world&#x2019;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. In January 2021, we acquired 3D Hubs, a leading online manufacturing platform based in Amsterdam, Netherlands, that provides customers with on-demand access to a global network of premium manufacturing partners. This acquisition creates the world's largest digital manufacturing platform, offering the broadest set of manufacturing services with the help of a global network of premium manufacturing providers. 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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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. The acquisition of 3D Hubs broadens our offer beyond our current manufacturing capabilities and provides a broader range of price and lead time options by leveraging a network of manufacturing partners to meet the holistic needs of our customers.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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&#x2019; 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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">Quick-turn CNC machining works best for prototyping, form and fit testing, jigs and fixtures and functional components for end-use applications.</p>

The increase in product developers was driven by our acquisition of 3D Hubs. Excluding the impact of 3D Hubs, our product developers declined 6.8% during the three months ended March 31, 2021 when compared to the same period in 2020. 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.</p>

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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><i><b>Operating Expenses</b></i></p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">Our recent growth in operating expenses is mainly due to the launch of our Protolabs 2.0 project in the fourth quarter of 2020. Expenses that were previously capitalizable as part of the project were expensed after the system was placed in service in November 2020. Our 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 goals, we anticipate continued substantial investments in technology and personnel, resulting in increased operating expenses.</p>
  <p style="margin: 0pt; text-align: center; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><i>Marketing and sales. </i>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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><i>Research and development.</i> 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, <i>Intangibles &#x2014; Goodwill and Other, Internal-Use Software</i>. 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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><i>General and administrative.</i> 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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><i><b>Provision for Income Taxes</b></i></p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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 2021 and beyond will remain consistent based on the current tax laws.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">During the three months ended March 31, 2021, we served 22,605 unique product developers and engineers, an increase of 8.3% over the same period in 2020. The increase in product developers was driven by our acquisition of 3D Hubs. Excluding the impact of 3D Hubs, our product developers declined 6.8% during the three months ended March 31, 2021 when compared to the same period in 2020. 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.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">By product line, our revenue increase was driven by an 8.1% increase in 3D Printing revenue and a 2.9% increase in Injection Molding revenue, which was partially offset by a 3.1% decrease in CNC Machining revenue, a 7.6% decrease in Sheet Metal revenue and a 28.2% decrease in Other Revenue, in each case for the three months ended&#xa0;March 31, 2021 compared to the same period in 2020.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><i>Cost of Revenue. </i>Cost of revenue increased $3.8 million, or 6.6%, for the three months ended&#xa0;March 31, 2021 compared to the same period in 2020, which was greater than the rate of revenue increase of 0.9% for the three months ended&#xa0;March 31, 2021 compared to the same period in 2020. The increase in cost of revenue was driven by a $5.1 million increase resulting from our recent acquisition of 3D Hubs. The increase was partially offset by our legacy business where there was a decrease in headcount resulting in personnel and related cost decreases of $1.0 million, as well as a decrease in raw material and product costs of $0.5 million, which were partially offset by an increase in equipment and facility related costs of $0.2 million.</p>

The increase is primarily driven by our acquisition of 3D Hubs which provided $1.0 million in marketing and sales expense during the three months ended March 31, 2021. In our legacy business, personnel and related cost increases of $1.0 million were partially offset by marketing program cost decreases of $0.7 million.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><i>Research and Development. </i>Our research and development expenses increased $3.2 million, or 35.5%, during the three months ended&#xa0;March 31, 2021 compared to the same period in&#xa0;2020 primarily due to personnel and related cost increases of $2.8 million driven by personnel and contractor resources dedicated to the launch of our Protolabs 2.0 system.&#xa0;Expenses that were previously capitalizable as part of the project were expensed after the system was placed in service in November 2020. In addition, increases of $0.5 million resulted from our acquisition of 3D Hubs, which were partially offset by decreases of $0.1 in professional service costs.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><i>Other&#xa0;(Loss) Income, net. </i>We recognized other loss, net of $0.3 million for the three months ended March 31, 2021, a decrease of $1.4 million compared to other income, net of $1.1&#xa0;million for the three&#xa0;months ended March 31, 2020. Other loss, net&#xa0;for the three months ended&#xa0;March 31, 2021 primarily consisted of a $0.5 million loss on foreign currency, which was partially offset by $0.1 million in interest income on investments and $0.1 million in other income. Other income, net&#xa0;for the&#xa0;three months ended&#xa0;March 31, 2020 primarily consisted of $0.6&#xa0;million in interest income on investments and a $0.7 million gain on foreign currency, which was partially offset by a $0.2&#xa0;million in other expense.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><i>Provision for Income Taxes. </i>Our effective tax rate of 6.0% for the three months ended&#xa0;March 31, 2021 decreased 15.8% compared to 21.8% for the same period in 2020. 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. Our income tax provision of $0.2 million for the three months ended&#xa0;March 31, 2021 decreased $3.7 million&#xa0;compared to our income tax provision of $3.9&#xa0;million for the three months ended March 31, 2020, due to a combination of lower pre-tax income and the lower effective tax rate.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">Historically, we have primarily financed our operations and capital expenditures through cash flow from operations. We had cash and cash equivalents of $43.8 million as of March 31, 2021, a decrease of $83.8 million from December 31, 2020. The decrease in our cash was primarily due to cash used in investing activity for our acquisition of 3D Hubs of $127.7 million and purchases of property, equipment and other capital assets of $6.5 million, which were partially offset by net proceeds from investments in marketable securities of $44.1 million and cash generated through operations of $6.4 million.</p>

Cash flows from operating activities were $22.4&#xa0;million during the&#xa0;three months ended March 31, 2020 and primarily consisted of net income of $14.0&#xa0;million, adjusted for certain non-cash items, including depreciation and amortization of $8.0&#xa0;million, stock-based compensation expense of $3.0&#xa0;million and deferred taxes of $3.4&#xa0;million, which were partially offset by&#xa0;changes in operating assets and liabilities and other items totaling $6.0&#xa0;million.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">Cash flows from operating activities decreased $16.0 million during the&#xa0;three months ended March 31, 2021 compared to the same period in 2020, primarily due to decreases in net income of $10.3 million, decreases in changes in operating assets and liabilities of $7.7 million&#xa0;driven by timing of cash receipts and payments, and decreases in deferred taxes of $3.5 million, which were partially offset by increases in depreciation and amortization of $2.1 million, increases in stock-based compensation of $2.6 million and increases of $0.8 million in other items.</p>

  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;"><b>Foreign Currency Risk</b></p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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.</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#xa0;</p>
  <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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 losses of $0.5 million and foreign currency gains of $0.7&#xa0;million during the three months ended March 31, 2021 and 2020, respectively. The changes in foreign exchange rates had a positive impact of $1.6 million and negative impact of $0.6&#xa0;million for the&#xa0;three months ended March 31, 2021 and 2020, respectively.</p>

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&#x2019;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.</p>

Emphasis has been on the maintenance of effective internal controls throughout development and deployment of all phases. The Company evaluated and concluded the implementation of Protolabs 2.0 has not materially affected the Company's internal control over financial reporting. Based on this evaluation, 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.</p>

Except as otherwise disclosed herein, these adjustments consist of normal, recurring items. Operating results for interim periods are &lt;em style="font: inherit;"&gt;not&lt;/em&gt; necessarily indicative of results that &lt;em style="font: inherit;"&gt; may &lt;/em&gt;be expected for the fiscal year as a whole.&lt;/p&gt;

   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;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&#x2019;s Annual Report on Form &lt;em style="font: inherit;"&gt;10&lt;/em&gt;-K for the year ended&#160;&lt;em style="font: inherit;"&gt; December 31, 2020&lt;/em&gt; as filed with the Securities and Exchange Commission (SEC) on &lt;em style="font: inherit;"&gt; February 19, 2021.&lt;/em&gt;&lt;/p&gt;

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.

(&lt;em style="font: inherit;"&gt;&#x201c;3D&lt;/em&gt; Hubs&#x201d;), for $294.4 million, consisting of $127.7 million in cash and 863,995 shares of the Company's common stock valued at $166.7 million on the date of close. Up to an additional $52.8 million of contingent consideration is payable after closing, subject to the satisfaction of performance-based targets during fiscal year &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; and fiscal year &lt;em style="font: inherit;"&gt;2022,&lt;/em&gt; consisting of up to $25.0 million in cash and up to 143,983 shares of the Company's common stock valued at $27.8 million on the date of close.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;"&gt;&lt;em style="font: inherit;"&gt;3D&lt;/em&gt; Hubs is based in Amsterdam, Netherlands and is a leading online manufacturing platform that provides customers with on-demand access to a global network of approximately &lt;em style="font: inherit;"&gt;240&lt;/em&gt; premium manufacturing partners. The acquisition enhances the Company&#x2019;s customer value proposition by enabling the Company to more holistically serve customers&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;"&gt;The fair value of the consideration paid for this acquisition has been allocated on a preliminary basis to the assets purchased and liabilities assumed based on their estimated fair values as of the acquisition date, with any excess recorded as goodwill.&#160; The goodwill associated with the acquisition represents the strategic and growth opportunities by significantly expanding the customer offering with a network of premium manufacturing partners. The goodwill related to the acquisition is &lt;em style="font: inherit;"&gt;not&lt;/em&gt; deductible for tax purposes.&#160;&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;"&gt;On a preliminary basis, the Company recorded a contingent consideration liability of $10.3 million as of the acquisition date representing the amounts payable to former shareholders, as outlined under the terms of the merger agreement, payable subject to the satisfaction of performance-based targets during fiscal year &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; and fiscal year &lt;em style="font: inherit;"&gt;2022,&lt;/em&gt; consisting of up to &lt;em style="font: inherit;"&gt;$25.0&lt;/em&gt; million in cash and up to &lt;em style="font: inherit;"&gt;143,983&lt;/em&gt; shares of the Company's common stock valued at &lt;em style="font: inherit;"&gt;$27.8&lt;/em&gt; million on the date of close. The fair value of the contingent consideration (Level &lt;em style="font: inherit;"&gt;3&lt;/em&gt;) is determined using a Monte Carlo pricing model. Once final, subsequent changes in the fair value of the contingent consideration liabilities will be recorded in the Consolidated Statements of Comprehensive Income. Fluctuations due to foreign currency translation will be recorded in the Consolidated Statements of Shareholders&#x2019; Equity.&lt;/p&gt;
   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;"&gt;The results of &lt;em style="font: inherit;"&gt;3D&lt;/em&gt; Hubs since the date of acquisition have been included with Protolabs' results.

   &lt;p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;"&gt;The acquisition has been accounted for under the acquisition method of accounting in accordance with ASC &lt;em style="font: inherit;"&gt;805,&lt;/em&gt; &lt;i&gt;Business Combinations&lt;/i&gt;. As of &lt;em style="font: inherit;"&gt; March 31, &lt;/em&gt;the allocation of purchase price to assets and liabilities is preliminary.

   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;Intangible assets increased $34.7 million during the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; March 31, 2021&lt;/em&gt; as a result of our acquisition of &lt;em style="font: inherit;"&gt;3D&lt;/em&gt; Hubs.

Foreign currency losses related to intangible assets were $0.6 million as of &lt;em style="font: inherit;"&gt; March 31, 2021. &lt;/em&gt;There was no foreign currency translation impact as of &lt;em style="font: inherit;"&gt; December 31, 2020. &lt;/em&gt;Amortization expense for intangible assets was $1.5&#160;million and $0.8&#160;million for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended&#160;&lt;em style="font: inherit;"&gt; March 31, 2021 &lt;/em&gt;and &lt;em style="font: inherit;"&gt;2020&lt;/em&gt;, respectively.&lt;/p&gt;

   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;Accounting Standards Codification, &lt;i&gt;Fair Value Measuremen&lt;/i&gt;t (ASC &lt;em style="font: inherit;"&gt;820&lt;/em&gt;), 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 &lt;em style="font: inherit;"&gt;820&lt;/em&gt; also establishes a fair value hierarchy that requires classification based on observable and unobservable inputs when measuring fair value. There are &lt;em style="font: inherit;"&gt;three&lt;/em&gt; levels of inputs that &lt;em style="font: inherit;"&gt; may &lt;/em&gt;be used to measure fair value:&lt;/p&gt;

   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;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, marketable securities and contingent consideration. The Company&#x2019;s cash consists of bank deposits. The Company&#x2019;s cash equivalents measured at fair value consist of money market mutual funds. The Company determines the fair value of these investments using Level &lt;em style="font: inherit;"&gt;1&lt;/em&gt; inputs. The Company's marketable securities consist of&#160;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 &lt;em style="font: inherit;"&gt;1&lt;/em&gt;). 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 &lt;em style="font: inherit;"&gt;2&lt;/em&gt;). The Company's contingent consideration is owed to the former shareholders of &lt;em style="font: inherit;"&gt;3D&lt;/em&gt; Hubs and is determined using the Monte Carlo pricing model (Level &lt;em style="font: inherit;"&gt;3&lt;/em&gt;).&lt;/p&gt;

   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;The Company invests in short-term and long-term agency, municipal, corporate and other debt securities. As of &lt;em style="font: inherit;"&gt; March 31, 2021 &lt;/em&gt;the securities are categorized as available-for-sale and are recorded at fair value. As of &lt;em style="font: inherit;"&gt; December 31, 2020, &lt;/em&gt;the securities were categorized as held-to-maturity and were recorded at amortized cost, net of an allowance for credit losses. The change in categorization was a result of the sale of securities in the &lt;em style="font: inherit;"&gt;first&lt;/em&gt; quarter of &lt;em style="font: inherit;"&gt;2021&lt;/em&gt; in order to partially fund the acquisition of &lt;em style="font: inherit;"&gt;3D&lt;/em&gt; Hubs and did &lt;em style="font: inherit;"&gt;not&lt;/em&gt; have a material impact on our financial statements.

   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;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 &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended&#160;&lt;em style="font: inherit;"&gt; March 31, 2021&lt;/em&gt; and &lt;em style="font: inherit;"&gt;2020&lt;/em&gt;, the Company recorded an income tax provision of $0.2 million and $3.9&#160;million, respectively.&#160;The income tax provision is based on the estimated annual effective tax rate for the year applied to pre-tax income. The results for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; March 31, 2021 &lt;/em&gt;reflect losses in jurisdictions that are &lt;em style="font: inherit;"&gt;not&lt;/em&gt; eligible for tax benefits on account of valuation allowances. The effective income tax rate for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended&#160;&lt;em style="font: inherit;"&gt; March 31, 2021&lt;/em&gt; was 6.0 percent compared to 21.8&#160;percent in the same period of the prior year. The effective tax rate decreased by 15.8 percent&#160;for the &lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended&#160;&lt;em style="font: inherit;"&gt; March 31, 2021&lt;/em&gt; when compared to the same period in&#160;&lt;em style="font: inherit;"&gt;2020&lt;/em&gt;, primarily due to an increase in tax benefits from the vesting of restricted stock and the exercise of stock options.&lt;/p&gt;
   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;The effective income tax rate for the&#160;&lt;em style="font: inherit;"&gt;three&lt;/em&gt; months ended &lt;em style="font: inherit;"&gt; March 31, 2021&lt;/em&gt; 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.&lt;/p&gt;
   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;The Company had unrecognized tax benefits totaling $4.9 million as of &lt;em style="font: inherit;"&gt; March 31, 2021&lt;/em&gt; and $4.8&#160;million as of&#160;&lt;em style="font: inherit;"&gt; December 31, 2020&lt;/em&gt;, respectively, all of which, if recognized, would affect the Company&#x2019;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.&lt;/p&gt;
   &lt;p style="margin: 0pt; text-align: left; font-family: &amp;quot;Times New Roman&amp;quot;, Times, serif; font-size: 10pt;"&gt;&#160;&lt;/p&gt;
   &lt;p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;"&gt;On &lt;em style="font: inherit;"&gt; March 11, 2021, &lt;/em&gt;the President signed into law the ARP Act, a legislative package which is generally &lt;em style="font: inherit;"&gt;not&lt;/em&gt; significant to the Company's current tax footprint; however, the Company will continue to assess the ARP Act on an ongoing basis. Similar tax provisions and other stimulus measures have been granted either before or after &lt;em style="font: inherit;"&gt; March 31, 2021 &lt;/em&gt;by certain foreign and U.S. state jurisdictions, which the Company continues to evaluate and apply, if applicable.&lt;/p&gt;

   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#160;</p>
   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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&#160;are excluded from the calculation of dilutive potential common shares until the performance conditions have been satisfied.</p>

   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#160;</p>
   <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">On <em style="font: inherit;"> January 22, 2021, </em>the Company acquired all outstanding shares of <em style="font: inherit;">3D</em> Hubs, Inc. (<em style="font: inherit;">&#8220;3D</em> Hubs&#8221;), for $294.4 million, consisting of $127.7 million in cash and 863,995 shares of the Company's common stock valued at $166.7 million on the date of close. Up to an additional $52.8 million of contingent consideration is payable after closing, subject to the satisfaction of performance-based targets during fiscal year <em style="font: inherit;">2021</em> and fiscal year <em style="font: inherit;">2022,</em> consisting of up to $25.0 million in cash and up to 143,983 shares of the Company's common stock valued at $27.8 million on the date of close.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;"><em style="font: inherit;">3D</em> Hubs is based in Amsterdam, Netherlands and is a leading online manufacturing platform that provides customers with on-demand access to a global network of approximately <em style="font: inherit;">240</em> premium manufacturing partners. The acquisition enhances the Company&#8217;s customer value proposition by enabling the Company to more holistically serve customers</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">The fair value of the consideration paid for this acquisition has been allocated on a preliminary basis to the assets purchased and liabilities assumed based on their estimated fair values as of the acquisition date, with any excess recorded as goodwill.&#160; The goodwill associated with the acquisition represents the strategic and growth opportunities by significantly expanding the customer offering with a network of premium manufacturing partners. The goodwill related to the acquisition is <em style="font: inherit;">not</em> deductible for tax purposes.&#160;</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">On a preliminary basis, the Company recorded a contingent consideration liability of $10.3 million as of the acquisition date representing the amounts payable to former shareholders, as outlined under the terms of the merger agreement, payable subject to the satisfaction of performance-based targets during fiscal year <em style="font: inherit;">2021</em> and fiscal year <em style="font: inherit;">2022,</em> consisting of up to <em style="font: inherit;">$25.0</em> million in cash and up to <em style="font: inherit;">143,983</em> shares of the Company's common stock valued at <em style="font: inherit;">$27.8</em> million on the date of close. The fair value of the contingent consideration (Level <em style="font: inherit;">3</em>) is determined using a Monte Carlo pricing model. Once final, subsequent changes in the fair value of the contingent consideration liabilities will be recorded in the Consolidated Statements of Comprehensive Income. Fluctuations due to foreign currency translation will be recorded in the Consolidated Statements of Shareholders&#8217; Equity.</p>
   <p style="font-family:'Times New Roman';font-size:10pt;font-variant:normal;margin:0pt;">&#160;</p>
   <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">The results of <em style="font: inherit;">3D</em> Hubs since the date of acquisition have been included with Protolabs' results. Pro forma disclosures of the consolidated results of the Company with the full year effects of <em style="font: inherit;">3D</em> Hubs, as if the acquisition had occurred on <em style="font: inherit;"> January 1, 2020, </em>have <em style="font: inherit;">not</em> been separately presented since the impact to the Company's results of operations was <em style="font: inherit;">not</em> material.</p>

   <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">The acquisition has been accounted for under the acquisition method of accounting in accordance with ASC <em style="font: inherit;">805,</em> <i>Business Combinations</i>. As of <em style="font: inherit;"> March 31, </em>the allocation of purchase price to assets and liabilities is preliminary.

The Company&#8217;s cash consists of bank deposits. The Company&#8217;s cash equivalents measured at fair value consist of money market mutual funds. The Company determines the fair value of these investments using Level <em style="font: inherit;">1</em> inputs. The Company's marketable securities consist of&#160;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 <em style="font: inherit;">1</em>). 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 <em style="font: inherit;">2</em>). The Company's contingent consideration is owed to the former shareholders of <em style="font: inherit;">3D</em> Hubs and is determined using the Monte Carlo pricing model (Level <em style="font: inherit;">3</em>).</p>

   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#160;</p>
   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">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 <em style="font: inherit;">three</em> months ended&#160;<em style="font: inherit;"> March 31, 2021</em> and <em style="font: inherit;">2020</em>, the Company recorded an income tax provision of $0.2 million and $3.9&#160;million, respectively.&#160;The income tax provision is based on the estimated annual effective tax rate for the year applied to pre-tax income. The results for the <em style="font: inherit;">three</em> months ended <em style="font: inherit;"> March 31, 2021 </em>reflect losses in jurisdictions that are <em style="font: inherit;">not</em> eligible for tax benefits on account of valuation allowances. The effective income tax rate for the <em style="font: inherit;">three</em> months ended&#160;<em style="font: inherit;"> March 31, 2021</em> was 6.0 percent compared to 21.8&#160;percent in the same period of the prior year. The effective tax rate decreased by 15.8 percent&#160;for the <em style="font: inherit;">three</em> months ended&#160;<em style="font: inherit;"> March 31, 2021</em> when compared to the same period in&#160;<em style="font: inherit;">2020</em>, primarily due to an increase in tax benefits from the vesting of restricted stock and the exercise of stock options.</p>
   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#160;</p>
   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">The effective income tax rate for the&#160;<em style="font: inherit;">three</em> months ended <em style="font: inherit;"> March 31, 2021</em> 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.</p>
   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#160;</p>
   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">The Company had unrecognized tax benefits totaling $4.9 million as of <em style="font: inherit;"> March 31, 2021</em> and $4.8&#160;million as of&#160;<em style="font: inherit;"> December 31, 2020</em>, respectively, all of which, if recognized, would affect the Company&#8217;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.</p>
   <p style="margin: 0pt; text-align: left; font-family: &quot;Times New Roman&quot;, Times, serif; font-size: 10pt;">&#160;</p>
   <p style="font-family: Times New Roman; font-size: 10pt; font-variant: normal; margin: 0pt;">On <em style="font: inherit;"> March 11, 2021, </em>the President signed into law the ARP Act, a legislative package which is generally <em style="font: inherit;">not</em> significant to the Company's current tax footprint; however, the Company will continue to assess the ARP Act on an ongoing basis. Similar tax provisions and other stimulus measures have been granted either before or after <em style="font: inherit;"> March 31, 2021 </em>by certain foreign and U.S. state jurisdictions, which the Company continues to evaluate and apply, if applicable.</p>

That is the same as the standard deviation of the differences in the natural logarithms of the stock prices plus dividends, if any, over the period.",
