Finally, we expressly disclaim any intent or obligation to update any forward-looking statements to reflect subsequent events or circumstances. 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 3DHubs, Inc. ) (Hubs) in 2021, we are able to provide our customers access to a global network of premium manufacturing partners who reside acrossNorth America ,Europe andAsia , 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. OnMay 27, 2022 , our board of directors approved a plan for the closure of our manufacturing facility inJapan and announced an intention to cease operations in the region. Affected employees inJapan will receive severance and other transition assistance that meet or exceed local requirements. We expect to substantially complete the closure plan within the next year. Our decision to close theJapan business resulted in$5.2 million in operating expenses during the three and six months endedJune 30, 2022 . Operating expenses included$2.2 million of employee severance,$1.2 million related to the write-down of fixed assets,$0.9 million of facility-related charges,$0.6 million in goodwill impairment charges and$0.3 million in other closure related charges for the three and six months endedJune 30, 2022 . 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 toProto 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. 16

Table of Contents 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 metrics and trends
Revenue Our operations are comprised of three geographic operating segments inthe United States ,Europe andJapan . 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 offers;
? the introduction of our 3D printing product line through our acquisition of
Fine Line in 2014?
? extend 3D printing to
? the introduction of our line of sheet metal products through our acquisition of
Rapid Manufacturing Group, LLC in 2017; ? continuously improving the usability of our product lines such as our web-centric applications? and
? providing customers with on-demand access to a global network of
manufacturing partners through our acquisition of Hubs in 2021. During the three months endedJune 30, 2022 , we served 24,058 unique product developers and engineers who purchased our products through our web-based customer interface, an increase of 3.4% over the same period in 2021. During the six months endedJune 30, 2022 , we served 36,878 unique product developers and engineers who purchased our products through our web-based customer interface, an increase of 5.2% over the same period in 2021.
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, and foreign exchange rates. 17

Table of Contents Operating Expenses
Operating expenses include marketing and sales, research and development, and general and administrative expenses. Personnel costs are the largest component in each of these categories.
The launch of our Protolabs 2.0 project, an internal business systems initiative impacting both external customer-facing and internal back-end systems, inthe United States in the first quarter of 2021, and our acquisition of Hubs inJanuary 2021 , led to higher operating expenses in the first six months of 2021. 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 ofJapan business. Closure ofJapan business expense is driven by our decision to close theJapan manufacturing facility and exit theJapan 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 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 2022 and beyond may differ from historical effective tax rates due to increases in losses in foreign 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. 18

Changes in fair value of contingent consideration. We had no contingent consideration liabilities recorded in 2022. The change in fair value of contingent consideration associated with the acquisition of Hubs was
Other income (loss), net. We recognized no other income, net for the three months endedJune 30, 2022 , a decrease of$0.1 million compared to other income, net of$0.1 million for the three months endedJune 30, 2021 . Other income, net for the three months endedJune 30, 2022 primarily consisted of a$0.3 million loss on foreign currency, which was offset by interest income on investments and other income. Other income, net for the three months endedJune 30, 2021 primarily consisted of a$0.1 million gain on foreign currency and interest income on investments. Provision for Income Taxes. Our effective tax rate of 50.8% for the three months endedJune 30, 2022 increased 30.3% compared to 20.5% for the same period in 2021. The increase in the effective tax rate is primarily due to a decrease in tax benefits from the vesting of restricted stock and the exercise of stock options, as well as an increase in losses in jurisdictions, primarilyJapan , that are not eligible for tax benefits due to valuation allowances. Our income tax provision of$2.6 million for the three months endedJune 30, 2022 decreased$0.7 million compared to our income tax provision of$3.3 million for the three months endedJune 30, 2021 . 21
