	Note 1 – Basis of Presentation
	The unaudited interim Consolidated Financial Statements of Proto Labs, Inc. (Proto Labs, 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. These statements are unaudited but, in the opinion of management, reflect all adjustments necessary for a fair presentation of the Company’s statement 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, 2013 as filed with the Securities and Exchange Commission (SEC) on February 28, 2014.
	The accompanying Consolidated Balance Sheet as of December 31, 2013 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 Form 10-Q should be read in conjunction with the Company’s Consolidated Financial Statements and Notes included in the Annual Report on Form 10-K filed on February 28, 2014 as referenced above.

	Note 2 – Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2014-09, Revenue from Contracts with Customers. This ASU is a comprehensive new revenue recognition model that requires a company to recognize revenue from the transfer of goods or services to customers in an amount that reflects the consideration that the entity expects to receive in exchange for those goods or services. The Company is required to adopt the new pronouncement on January 1, 2017 using one of two retrospective application methods. The Company is evaluating the application method and the impact of this new standard on our financial statements.
	In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern, to provide guidance on management’s responsibility in evaluating whether there is substantial doubt about a company’s ability to continue as a going concern and to provide related footnote disclosures. The Company is required to adopt the new pronouncement for the annual period ending after December 15, 2016, with early adoption permitted. We believe the impact of ASU 2014-15 will not affect the Company.
	There are no other new accounting pronouncements that are expected to have a significant impact on the Company’s consolidated financial statements.

	Note 3 – Business Combinations
	On April 23, 2014, the Company acquired 100% of the outstanding shares of FineLine Prototyping, Inc. (“FineLine”) for $33.9 million net cash consideration, which was funded with cash available in the United States and the sale of $15.5 million of held-to-maturity securities. The shares of FineLine acquired through the Stock Purchase Agreement (“Agreement”) were initially issued in a private transaction exempt from the registration under the Securities Act of 1933 and the operations of FineLine will be integrated into the operations of the Company. Under the terms of the Agreement, the Company is obligated to make an additional cash payment of up to $3.0 million, contingent upon both the achievement of 2014 revenue goals and certain milestones relating to the integration of FineLine’s operations with the Company.
	FineLine is based in Raleigh, North Carolina and is a leading producer of parts using additive manufacturing technologies, often times referred to as 3D printing. FineLine produces high-quality parts using stereolithography (SLA), selective laser sintering (SLS) and direct metal laser sintering (DMLS) technologies to customers in a wide variety of industries, including medical, aerospace, computer/electronics, consumer products and industrial machinery, among others. Along with Protomold and Firstcut, the Company will offer these technologies to its customers under the Fineline product name.
	Consistent with the provisions of Accounting Standards Codification (ASC) 805, Business Combinations (ASC 805), the Company accrued the contingent payment on the date of acquisition after determining its fair value of $3.0 million in arriving at $36.9 million of total consideration, net of cash acquired. The contingent consideration liability is reflected in accrued liabilities and other as of September 30, 2014 and continues to be remeasured to fair value at each reporting period with changes in fair value reflected in the Consolidated Statements of Comprehensive Income. To date as of September 30, 2014, the Company has made payments of $0.8 million related to the attainment of milestones and as of September 30, 2014, the contingent consideration balance totaled $2.2 million.
	The fair value of the consideration paid for this acquisition was allocated to the assets purchased and liabilities assumed based on their estimated fair values as of the acquisition date, with any excess recorded as goodwill. The goodwill associated with the acquisition is deductible for tax purposes and represents the strategic and growth opportunities from strengthening the Company’s portfolio of rapid prototyping product offerings. The addition of additive manufacturing expands Proto Labs’ products to address a wider spectrum of need for the product developer. From concept models, to form and fit testing, to functional testing and short-run production, the acquisition of FineLine allows the Company to offer a broader range of quick-turn custom parts with speed, reliability and consistency.
	The results of FineLine since the date of acquisition and pro forma disclosures of the consolidated results of the Company with the full year effects of FineLine have not been separately presented since the impact to the Company's results of operations was not material.
	The acquisition has been accounted for under the acquisition method of accounting in accordance with ASC 805. As of September 30, 2014, this allocation for FineLine remains preliminary as it relates to the valuation of certain working capital accounts, intangible assets and taxes. The preliminary allocation of the purchase price to assets acquired and liabilities assumed is as follows:
	(in thousands)

	Current assets	$	1,248

	Note 5 – 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 the 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.

	Note 6 – Fair Value Measurements
	ASC 820, 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 which requires classification based on observable and unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value:
	Level 1—Quoted prices in active markets for identical assets or liabilities.
	Level 2—Observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.
	Level 3—Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.
	The Company’s cash consists of bank deposits. The Company’s cash equivalents measured at fair value consist of money market mutual funds. The Company determines the fair value of these investments using Level 1 inputs.
	A summary of financial assets as of September 30, 2014 and December 31, 2013 measured at fair value on a recurring basis follows:

	The Company invests in short-term and long-term agency, municipal, corporate, commercial paper and other debt securities. The securities are categorized as held-to-maturity and are recorded at amortized cost. Categorization as held-to-maturity is based on the Company’s ability and intent to hold these securities to maturity. Information regarding the Company’s short-term and long-term marketable securities as of September 30, 2014 and December 31, 2013 is as follows:

	Total marketable securities		$	100,362	$	86	$	(72	)	$	100,376
	Fair values for the corporate debt securities are 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 commercial paper are primarily determined using dealer quotes or quoted market prices for similar securities (Level 2).
	The Company tests for other than temporary losses on a quarterly basis and has considered the unrealized losses indicated above to be temporary in nature. The Company intends to hold the investments to maturity and recover the full principal.
	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, 2014 balance of held-to-maturity debt securities by contractual maturity is shown in the following table at amortized cost. Actual maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

	Under the 2012 Long-Term Incentive Plan (2012 Plan), the Company has the ability to grant stock options, stock appreciation rights (SARs), restricted stock, stock units, other stock-based awards and cash incentive awards. Awards under the 2012 Plan will have a maximum term of ten years from the date of grant. The compensation committee may provide that the vesting or payment of any award will be subject to the attainment of specified performance measures in addition to the satisfaction of any continued service requirements and the compensation committee will determine whether such measures have been achieved. The per share exercise price of stock options and SARs granted under the 2012 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’s 2012 Employee Stock Purchase Plan (ESPP), allows eligible employees to purchase shares of the Company’s common stock at a discount through payroll deductions of up to 15 percent of their eligible compensation, subject to plan limitations. The ESPP provides for six-month offering periods ending May 15 and November 15, respectively. At the end of each offering period, employees are able to purchase shares at 85 percent of the lower of the fair market value of the Company’s common stock on the first trading day of the offering period or on the last trading day of the offering period.
	Stock-Based Compensation Expense
	Stock-based compensation expense was $1.4 million and $0.9 million for the three months ended September 30, 2014 and 2013, respectively, and $3.6 and $2.6 million for the nine months ended September 30, 2014 and 2013, respectively.
	Stock Options
	A summary of stock option activity for the nine months ended September 30, 2014 is as follows:
					Weighted-
					Average
		Stock Options			Exercise Price
	Options outstanding at December 31, 2013		1,143,250		$	19.03

	Exercisable at September 30, 2014		394,085		$	15.46
	The outstanding options generally have a term of ten years. For employees, options granted become exercisable ratably over the vesting period, which is generally a five-year period beginning on the first anniversary of the grant date, subject to the employee’s continuing service to the Company. For directors, options generally become exercisable in full on the first anniversary of the grant date.
	The weighted-average grant date fair value of options that were granted during the nine months ended September 30, 2014 was $32.76.
	The following table provides the assumptions used in the Black-Scholes pricing model valuation of options during the nine months ended September 30, 2014 and 2013, respectively:

	Note 11 – 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, 2014 and 2013 the Company recorded an income tax provision of $5.0 million and $4.6 million, respectively. For the nine months ended September 30, 2014 and 2013 the Company recorded an income tax provision of $14.4 million and $11.8 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, 2014 was 32.5 percent compared with 34.0 percent in the same period of the prior year. The effective income tax rate for each of the nine months ended September 30, 2014 and 2013 was 31.4 percent.
	The effective income tax rate for the three and nine months ended September 30, 2014 differs from the U.S. federal statutory rate of 35 percent due primarily to the mix of revenue earned in domestic and foreign tax jurisdictions and deductions for which the Company qualifies.
	The Company had liabilities related to unrecognized tax benefits totaling $0.9 million at September 30, 2014 and $0.7 million December 31, 2013, all of which, if recognized, would affect the Company’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.
	During the quarter ended September 30, 2014, the Company decreased its prior year uncertain tax positions by $0.4 million due to the expiration of the statutes of limitations on the Company’s 2010 federal income tax return.  Also, during the quarter ended September 30, 2014, the Company increased its prior year and current year uncertain tax positions by $0.4 million and $0.5 million, respectively.  The increase was due to certain tax positions not meeting the more-like-than-not standard for accounting for uncertain tax positions under the Company’s current facts and circumstances.
	Based upon the information available as of September 30, 2014, the Company anticipates the amount of uncertain tax positions will change in the next twelve months; however, the change cannot be estimated.
