TABLE OF CONTENTS

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited consolidated financial statements and related notes appearing elsewhere in this Quarterly Report on Form 10-Q and our Annual Report on Form 10-K for the year ended December 31, 2015 .

Forward-Looking Statements

Overview

We are a leading online and technology-enabled manufacturer of quick-turn, on-demand 3D printed, CNC-machined and injection-molded custom parts for prototyping and low-volume production. We provide “Real Parts, Really Fast” to product developers and engineers worldwide, who are under increasing pressure to bring their finished products to market faster than their competition. We believe custom parts manufacturing has historically been an underserved market due to the inefficiencies inherent in the quotation, equipment set-up and non-recurring engineering processes required to produce custom parts. Our proprietary technology eliminates most of the time-consuming and expensive skilled labor conventionally required to quote and manufacture parts. Our customers conduct nearly all of their business with us over the Internet. We target our products to the millions of product developers and engineers who use three-dimensional computer-aided design (3D CAD) software to design products across a diverse range of end-markets.

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

Injection Molding ( Protomold )

Our Injection Molding (Protomold) product line uses our 3D CAD-to-CNC machining technology for the automated design and manufacture of thermoplastic, metal, or liquid silicone injection molds, which are then used to produce custom injection-molded parts on commercially available equipment. Our Injection Molding (Protomold) product line is used for prototype, on-demand and low-volume production. Prototype quantities typically range from 25 to 100 parts. Because we retain possession of the molds, customers who need low-volume production often come back to Proto Labs’ Injection Molding product line for additional quantities typically ranging up to 10,000 parts or more. They do so to support pilot production 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 will only be released in a limited quantity, or because they need end-of-life production support. These additional part orders typically occur on approximately half of the molds that we make, typically accounting for approximately half of our total Injection Molding (Protomold) revenue.

CNC Machining ( Firstcut )

Our CNC Machining (Firstcut) product line uses commercially available CNC machines to cut plastic or metal blocks or bars into one or more custom parts based on the 3D CAD model uploaded by the product developer or engineer. Our efficiencies derive from the automation of the programming of these machines and a proprietary fixturing process. The CNC Machining (Firstcut) product line is well suited to produce small quantities, typically in the range of one to 200 parts.

3D Printing ( Fineline )

Our 3D Printing (Fineline) includes stereolithography (SL), selective laser sintering (SLS) and direct metal laser sintering (DMLS) 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. 3D Printing is well suited to produce small quantities, typically in the range of one to 50 parts.

Key Financial Measures and Trends

Revenue

The Company’s operations are conducted in three geographic markets consisting of the United States, Europe and Japan, which we believe are three of the largest geographic markets where product developers and engineers are located. Revenue within each of our United States and Europe markets is derived from our Injection Molding (Protomold), CNC Machining (Firstcut) and 3D Printing (Fineline) product lines. Revenue within our Japan market is derived from our Injection Molding (Protomold) and CNC Machining (Firstcut) product lines. Our historical and current efforts to increase revenue have been directed at gaining new customers and selling to our existing customer base by:

Excluding product developers and engineers gained through the acquisition of Alphaform, we served 13,519 unique product developers and engineers during the three months ended June 30 , 2016, an increase of 14.4% over the same period in 2015. We served 20,240 unique product developers and engineers during the six months ended June 30, 2016, an increase of 17.7% over the same period in 2015.

Cost of Revenue, Gross Profit and Gross Margin

Cost of revenue consists primarily of raw materials, employee compensation, benefits, stock-based compensation, equipment depreciation, facilities costs and overhead allocations associated with the manufacturing process for molds and custom parts. We expect cost of revenue to increase in absolute dollars, but remain relatively constant as a percentage of total revenue.

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

Our recent growth in operating expenses is mainly due to higher headcounts to support our growth and expansion, and we expect that trend to continue. Our business strategy is to continue to be a leading online and technology-enabled manufacturer of quick-turn, on-demand 3D printed, CNC-machined, CNC-turned and injection-molded 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.

Marketing and sales. Marketing and sales expense consists primarily of employee compensation, benefits, commissions, stock-based compensation, marketing programs such as print and pay-per-click advertising, trade shows, direct mail 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.

Research and development. Research and development expense consists primarily of employee compensation, benefits, stock-based compensation, depreciation on equipment, outside services and other related overhead. All of our research and development costs have been expensed as incurred. We expect research and development expense to increase in the future as we seek to enhance and expand our product line offerings.

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

Other Income (Expense), N et

Other income (expense), 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 I ncome T axes

Provision for income taxes is comprised of federal, state, local and foreign taxes based on pre-tax income. We expect income taxes to increase as our taxable income increases and we expect our effective tax rate to remain relatively constant.
