Notes to Condensed Consolidated Financial Statements (Unaudited)

NOTE A – General

Business Description

We are a leading provider of cloud-based supply chain management solutions, providing prewired, proven integrations and comprehensive retail performance analytics to thousands of customers worldwide. We provide our solutions through the SPS Commerce platform, a cloud-based software suite that improves the way suppliers, retailers, distributors and other customers manage and fulfill orders. We derive the majority of our revenues from thousands of monthly recurring subscriptions from businesses that utilize our solutions.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of SPS Commerce, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP. We have included all normal recurring adjustments considered necessary to give a fair statement of our financial position, results of operations and cash flows for the interim periods shown. Operating results for these interim periods are not necessarily indicative of the results to be expected for the full year. The December 31, 2013 condensed consolidated balance sheet data was derived from our audited financial statements at that date. For further information, refer to the consolidated financial statements and accompanying notes for the year ended December 31, 2013 included in our Annual Report on Form 10-K as filed with the Securities and Exchange Commission on February 20, 2014.

Use of Estimates

Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Significant Accounting Policies

During the nine months ended September 30, 2014, there were no material changes in our significant accounting policies. See Note A to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the Securities and Exchange Commission on February 20, 2014, for additional information regarding our significant accounting policies.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued new accounting requirements for the recognition of revenue from contracts with customers. These new requirements are effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. We are currently evaluating the impact of this guidance on our results of operations and financial position.

NOTE B – Goodwill and Intangible Assets, net

There was no change in our goodwill for the nine months ended September 30, 2014.

Intangible assets included the following (in thousands):

	September 30, 2014							December 31, 2013
	Carrying Amount		Accumulated Amortization			Net		Carrying Amount		Accumulated Amortization			Net
Subscriber relationships	$	23,160	$	(8,270	)	$	14,890	$	23,160	$	(6,376	)	$	16,784
Non-competition agreements		1,710		(1,562	)		148		1,710		(1,412	)		298
	$	24,870	$	(9,832	)	$	15,038	$	24,870	$	(7,788	)	$	17,082

Amortization expense for intangible assets was $645,000 and $2.0 million for the three and nine months ended September 30, 2014, and $1.0 million and $2.4 million for the three and nine months ended September 30, 2013, respectively.

At September 30, 2014, future amortization expense for intangible assets was as follows (in thousands):

Remainder of 2014	$	643
2015		2,578
2016		2,578
2017		2,557
2018		2,062
Thereafter		4,620
	$	15,038

NOTE C – Line of Credit

We have a revolving credit agreement with JPMorgan Chase Bank, N.A. which provides for a $20 million revolving credit facility that we may draw upon from time to time, subject to certain terms and conditions, and will mature on September 30, 2016.

There were no borrowings outstanding at September 30, 2014 and we were in compliance with all covenants under the revolving credit agreement as of that date.

NOTE D – Stock-Based Compensation

Our equity compensation plans provide for the grant of incentive and nonqualified stock options, as well as other stock-based awards including restricted stock and restricted stock units, to employees, non-employee directors and other consultants who provide services to us. Restricted stock awards result in the issuance of new shares when granted. For other stock-based awards, new shares are issued when the award is exercised, vested or released according to the terms of the agreement. In January 2014, 965,527 additional shares were reserved for future issuance under our 2010 Equity Incentive Plan. At September 30, 2014, there were approximately 2.6 million shares available for grant under approved equity compensation plans.

7

We recorded non-cash stock-based compensation expense of $1.3 million and $4.0 million for the three and nine months ended September 30, 2014, and $1.1 million and $3.1 million for the three and nine months ended September 30, 2013, respectively. This expense was allocated as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2014		2013		2014		2013
Cost of revenues	$	134	$	128	$	439	$	353
Operating expenses
Sales and marketing		469		378		1,423		1,106
Research and development		134		71		322		195
General and administrative		556		508		1,807		1,466
Total stock-based compensation expense	$	1,293	$	1,085	$	3,991	$	3,120

As of September 30, 2014, there was approximately $9.9 million of unrecognized stock-based compensation expense under our equity compensation plans, which is expected to be recognized on a straight line basis over a weighted average period of 2.7 years.

Stock Options

Stock options generally vest over four years and have a contractual term of seven to ten years from the date of grant. Our stock option activity was as follows:

	Options (#)			Weighted Average Exercise Price ($/share)
Outstanding at December 31, 2013		1,097,223		$	19.62
Granted		150,230			63.01
Exercised		(138,420	)		11.20
Forfeited		(12,334	)		41.36
Outstanding at September 30, 2014		1,096,699			26.38

Of the total outstanding options at September 30, 2014, 724,045 were exercisable with a weighted average exercise price of $17.68 per share. The total outstanding options had a weighted average remaining contractual life of 5.5 years.

The weighted average fair value per share of options granted during the first nine months of 2014 was $24.46 and this was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

Weighted-average volatility	41.8	%
Expected dividend yield	0	%
Expected life (in years)	4.2
Risk-free interest rate	1.06-1.55	%

Restricted Stock Units and Awards

Restricted stock units vest over four years and, upon vesting, the holder is entitled to receive shares of our common stock. With restricted stock awards, shares of our common stock are issued when the award is granted and the restrictions lapse over one year.

8

Our restricted stock units activity was as follows:

	Restricted Stock Units (#)			Weighted Average Grant Date Fair Value ($/share)
Outstanding at December 31, 2013		102,644		$	33.77
Granted		40,503			65.19
Vested and common stock issued		(28,271	)		32.77
Forfeited		(1,145	)		35.42
Outstanding at September 30, 2014		113,731			45.19

The number of restricted stock units outstanding at September 30, 2014 included 19,262 units that have vested but for which shares of common stock have not yet been issued pursuant to the terms of the agreement.

Our restricted stock awards activity was as follows:

	Restricted Stock Awards (#)			Weighted Average Grant Date Fair Value ($/share)
Outstanding at December 31, 2013		1,422		$	48.66
Restricted common stock issued		5,352			51.74
Restrictions lapsed		(3,861	)		50.79
Forfeited		(237	)		48.66
Outstanding at September 30, 2014		2,676			51.74

Employee Stock Purchase Plan

Our employee stock purchase plan allows participating employees to purchase shares of our common stock at a discount through payroll deductions. The plan is available to all employees subject to certain eligibility requirements. Participating employees may purchase common stock, on a voluntary after-tax basis, at a price that is the lower of 85% of the fair market value of one share of common stock at the beginning or end of each stock purchase period. The plan consists of two six-month offering periods, beginning on January 1 and July 1 of each calendar year. A total of 1.2 million shares of common stock are reserved for issuance under the plan.

For the offering period that began on January 1, 2014 and ended June 30, 2014, we withheld approximately $680,000 from employees participating in the plan. On June 30, 2014, approximately $672,000 of these funds was used to purchase 12,520 shares on behalf of the employees participating in the plan. The remaining funds were refunded to employees pursuant to the requirements of the plan. For the offering period that began on July 1, 2014 and will end on December 31, 2014, we have withheld approximately $358,000 as of September 30, 2014 from employees participating in the plan.

For the three and nine months ended September 30, 2014, we recorded approximately $85,000 and $286,000, respectively, of stock-based compensation expense associated with the employee stock purchase plan. The fair value was estimated based on the market price of our common stock at the beginning of each offering period and using the Black-Scholes option pricing model with the following assumptions:

Expected volatility	48.9	%
Expected dividend yield	0	%
Expected life (in years)	0.50
Risk-free interest rate	0.10	%

9

NOTE E – Income Taxes

We record our interim provision for income taxes by applying our estimated annual effective tax rate to our year-to-date pretax income and adjust the provision for discrete tax items recorded in the period. Differences between our effective tax rate and statutory tax rates are primarily due to the impact of meals and entertainment expense, employee stock purchase plan expense, as well as the federal R&D credit.

We recorded income tax expense of $532,000 and $1.2 million for the three and nine months ended September 30, 2014. We recorded income tax expense of $169,000 and $272,000 for the three and nine months ended September 30, 2013. Our provisions for income taxes included current foreign and state income tax expense, as well as deferred tax expense.

We are subject to U.S federal income tax as well as income tax in various state and international jurisdictions. We are generally subject to tax examinations for all prior years due to our net operating loss carryforwards. As of September 30, 2014, we were not under any income tax audits by tax authorities.

As of September 30, 2014 we do not have any unrecognized tax benefits. It is our practice to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. We do not expect any material changes in our unrecognized tax positions over the next 12 months.

NOTE F – Net Income Per Share

Basic net income per share has been computed using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share also includes the impact of our outstanding potential common shares, including options and restricted stock units. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net income per share.

The following table presents the components of the computation of basic and diluted net income per share for the periods indicated (in thousands, except per share amounts):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2014		2013		2014		2013
Numerator
Net income	$	838	$	270	$	1,850	$	757
Denominator
Weighted average common shares outstanding, basic		16,254		15,223		16,207		15,064
Options to purchase common stock		488		706		544		666
Restricted stock units		36		54		41		48
Employee stock purchase plan		2		3		1		3
Weighted average common shares outstanding, diluted		16,780		15,986		16,793		15,781
Net income per share
Basic	$	0.05	$	0.02	$	0.11	$	0.05
Diluted	$	0.05	$	0.02	$	0.11	$	0.05

The effect of approximately 126,000 outstanding potential common shares was excluded from the calculation of diluted net income per share for each of the three and nine months ended September 30, 2014 because they were anti-dilutive. For each of the three and nine months ended September 30, 2013, the effect of all outstanding potential common shares was included in the calculation of diluted net income per share.

NOTE G – Subsequent Event

On October 12, 2014, we, together with our wholly owned subsidiary SPS Commerce Australia Pty Ltd, entered into and completed an asset purchase agreement with Leadtec Systems Australia Pty Ltd (“Leadtec”) and its affiliates, Advanced Barcode Solutions Pty Ltd, Scott Needham and Leading Technology Group Pty Ltd. Under the asset purchase agreement, we purchased and acquired from Leadtec substantially all of the assets used in Leadtec’s business. Leadtec is in the business of cloud-based integration solutions. We paid Leadtec $12.7 million in cash, issued 43,595 shares of our common stock to Leadtec and assumed certain liabilities of Leadtec. This acquisition allows us to expand our geographical presence, expand our base of recurring revenue customers and add suppliers to our network. Our consolidated statements of income for the three and nine months ended September 30, 2014 included approximately $200,000 of fees related to this transaction.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are a leading provider of cloud-based supply chain management solutions, providing prewired, proven integrations and comprehensive retail performance analytics to thousands of customers worldwide. We provide our solutions through the SPS Commerce platform, a cloud-based software suite that improves the way suppliers, retailers, distributors and other customers manage and fulfill orders. We derive the majority of our revenues from thousands of monthly recurring subscriptions from businesses that utilize our solutions.

We plan to continue to grow our business by further penetrating the supply chain management market, increasing revenues from our customers as their businesses grow, expanding our distribution channels, expanding our international presence and, from time to time, developing new solutions and applications. We also intend to selectively pursue acquisitions that will add customers, allow us to expand into new regions or allow us to offer new functionalities.

For the three months ended September 30, 2014, our revenues were $32.5 million, an increase of 20% from the comparable period in 2013, and represented our 55^th consecutive quarter of increased revenues. Total operating expenses increased 15% and net income increased 210% for the same period in 2014 from 2013. Similar results were experienced for the nine months ended September 30, 2014 with increased revenues of 21%, increased operating expenses of 17% and increased net income of 144% compared to the same period in 2013.

Subsequent to September 30, 2014, on October 12, 2014, we entered into and completed an asset purchase agreement with Leadtec Systems Australia Pty Ltd (“Leadtec”), a privately-held cloud-based integration solutions company. This acquisition allows us to expand our geographical presence, expand our base of recurring revenue customers and add suppliers to our network. See Note G to our consolidated financial statements included in this Quarterly Report on Form 10-Q for additional information regarding this acquisition.

Key Financial Terms and Metrics

We have several key financial terms and metrics, including annualized average recurring revenues per recurring revenue customer, which we also refer to as wallet share. During the nine months ended September 30, 2014, there were no changes in the definitions of our key financial terms and metrics, which are discussed in more detail under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in our Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission on February 20, 2014.

To supplement our financial statements, we also provide investors with Adjusted EBITDA and non-GAAP income per share, both of which are non-GAAP financial measures. We believe that these non-GAAP measures provide useful information to management and investors regarding certain financial and business trends relating to our financial condition and results of operations. Our management uses these non-GAAP measures to compare the company’s performance to prior periods for trend analyses and planning purposes. Adjusted EBITDA is also used for purposes of determining executive and senior management incentive compensation. These measures are also presented to our board of directors.

11

These non-GAAP measures should not be considered a substitute for, or superior to, financial measures calculated in accordance with generally accepted accounting principles in the United States of America (“GAAP”). These non-GAAP financial measures exclude significant expenses and income that are required by GAAP to be recorded in our financial statements and are subject to inherent limitations. Investors should review the reconciliations of non-GAAP financial measures to the comparable GAAP financial measures that are included in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Critical Accounting Policies and Estimates

This discussion of our financial condition and results of operations is based upon our condensed consolidated financial statements, which are prepared in accordance with GAAP. The preparation of these financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues, costs and expenses and related disclosures. We base our estimates of the carrying value of certain assets and liabilities on historical experience and on various other assumptions that we believe to be reasonable. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates under different assumptions or conditions.

A critical accounting policy is one that is both material to the presentation of our financial statements and requires us to make difficult, subjective or complex judgments for uncertain matters that could have a material effect on our financial condition and results of operations. Accordingly, we believe that our policies for revenue recognition, the allowance for doubtful accounts, income taxes and stock-based compensation are the most critical to aid in fully understanding and evaluating our financial condition and results of operations.

During the nine months ended September 30, 2014, there were no changes in our significant accounting policies or estimates. See Note A to our consolidated financial statements included in this Quarterly Report on Form 10-Q and in our Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the Securities and Exchange Commission on February 20, 2014, for additional information regarding our accounting policies.

Three and Nine Months Ended September 30, 2014 compared to Three and Nine Months Ended September 30, 2013

Revenues. Revenues for the three months ended September 30, 2014 increased $5.5 million, or 20%, to $32.5 million from $27.0 million for the same period in 2013. Revenues for the nine months ended September 30, 2014 increased $16.1 million, or 21%, to $92.5 million from $76.4 million for the same period in 2013.

The increase in revenues for both the three and nine month periods resulted from two primary factors: the increase in recurring revenue customers and the increase in annualized average recurring revenues per recurring revenue customer, which we also refer to as wallet share.

• The number of recurring revenue customers increased 9% to 21,218 at September 30, 2014 from 19,387 at September 30, 2013.

• Annualized average recurring revenues per recurring revenue customer, or wallet share, increased 12% to $5,596 for the three months ended September 30, 2014 from $5,018 for the same period in 2013. This increase in wallet share was primarily attributable to increased fees resulting from increased usage of our solutions by our recurring revenue customers and growth in larger customers.

Recurring revenues from recurring revenue customers accounted for 90% of our total revenues for each of the three and nine months ended September 30, 2014, compared to 89% for each of the same periods in 2013. We anticipate that the number of recurring revenue customers and wallet share will continue to increase as we increase the number of solutions we offer and increase the penetration of those solutions across our customer base.

Cost of Revenues. Cost of revenues for the three months ended September 30, 2014 increased $1.7 million, or 21%, to $10.0 million from $8.2 million for the same period in 2013. Cost of revenues for the nine months ended September 30, 2014 increased $5.6 million, or 24%, to $28.9 million from $23.3 million for the same period in 2013. The increase in cost of revenues for the three and nine month periods in 2014 was primarily due to increased headcount in 2014 which resulted in higher personnel costs. Also contributing to the increase for both periods were increased expenses for software subscriptions in 2014 as compared to 2013. As a percentage of revenues, cost of revenues was 31% for each of the three months ended September 30, 2014 and 2013, compared to 31% and 30%, respectively, for each of the nine months ended September 30, 2014 and 2013. Going forward, we anticipate that cost of revenues will increase in absolute dollars as we continue to expand our business.

Sales and Marketing Expenses. Sales and marketing expenses for the three months ended September 30, 2014 increased $1.8 million, or 17%, to $12.0 million from $10.3 million for the same period in 2013. Sales and marketing expenses for the nine months ended September 30, 2014 increased $5.3 million, or 18%, to $34.5 million from $29.2 million for the same period in 2013. The increase in sales and marketing expenses for the three and nine month periods in 2014 was primarily due to increased headcount in 2014, which resulted in higher personnel costs, as well as increased commissions earned by sales personnel from new business. We also had increased promotional, occupancy, depreciation and stock-based compensation expenses in 2014 as compared to 2013. As a percentage of revenues, sales and marketing expenses were 37% for each of the three and nine months ended September 30, 2014 compared to 38% for each of the comparable periods in 2013. As we expand our business, we will continue to add resources to our sales and marketing efforts over time, and we expect that these expenses will continue to increase in absolute dollars.

Research and Development Expenses. Research and development expenses for the three months ended September 30, 2014 increased $532,000, or 19%, to $3.3 million from $2.8 million for the same period in 2013. Research and development expenses for the nine months ended September 30, 2014 increased $1.7 million, or 22%, to $9.7 million from $8.0 million for the same period in 2013. The increased research and development expenses for the three and nine month periods in 2014 were primarily due to increased headcount in 2014, which resulted in higher personnel costs. We also had increased expenses for depreciation and stock-based compensation in 2014 as compared to 2013. As a percentage of revenues, research and development expenses were approximately 10% for all periods presented in 2014 and 2013. As we enhance and expand our solutions and applications, we expect that research and development expenses will continue to increase in absolute dollars.

14

General and Administrative Expenses. General and administrative expenses for the three months ended September 30, 2014 increased $869,000, or 20%, to $5.2 million from $4.3 million for the same period in 2013. General and administrative expenses for the nine months ended September 30, 2014 increased $2.0 million, or 16%, to $14.5 million from $12.5 million for the same period in 2013. The increase in general and administrative expenses for the three and nine month periods in 2014 was primarily due to increased legal costs, including costs related to the Leadtec acquisition, and increased costs for computer software and hardware maintenance, stock-based compensation and personnel in 2014 as compared to 2013. As a percentage of revenues, general and administrative expenses were approximately 16% for all periods presented in 2014 and 2013. Going forward, we expect that general and administrative expenses will continue to increase in absolute dollars as we expand our business.

Income Tax Expense. We recorded income tax expense of $532,000 and $1.2 million for the three and nine months ended September 30, 2014. We recorded income tax expense of $169,000 and $272,000 for the three and nine months ended September 30, 2013. Our provisions for income taxes included current foreign and state income tax expense, as well as deferred tax expense. We expect that our annual effective income tax rate will be approximately 40%.

The increase in income tax expense for the three and nine months ended September 30, 2014, compared to the same periods in 2013, was primarily due to the increase in pretax book income in 2014. In addition, there was a discrete tax benefit of $117,000 in 2013 for the retroactive benefit of the 2012 federal R&D credit. The American Taxpayer Relief Act of 2012 was enacted on January 2, 2013 and extended the federal R&D credit from January 1, 2012 through December 31, 2013.

Adjusted EBITDA. Adjusted EBITDA, which is a non-GAAP measure of financial performance, consists of net income plus depreciation and amortization, interest expense, interest income, income tax expense, stock-based compensation expense and other adjustments as necessary for a fair presentation. For 2014 and 2013, other adjustments included the impact of a use tax refund related to items previously expensed. The following table provides a reconciliation of net income to Adjusted EBITDA (in thousands):

	Three Months Ended						Nine Months Ended

Non-GAAP Income Per Share. Non-GAAP income per share, which is also a non-GAAP measure of financial performance, consists of net income plus stock-based compensation expense and amortization expense related to intangible assets divided by the weighted average number of shares of common stock outstanding during each period. The following table provides a reconciliation of net income to non-GAAP income per share (in thousands, except per share amounts):

	Three Months Ended				Nine Months Ended

Liquidity and Capital Resources

At September 30, 2014, our principal sources of liquidity were cash and cash equivalents of $140.8 million and accounts receivable, net of allowance for doubtful accounts, of $13.6 million. Our working capital at September 30, 2014 was $149.7 million compared to $137.2 million at December 31, 2013. The increase in working capital from December 31, 2013 to September 30, 2014 resulted from the following:

• $9.5 million increase in cash and cash equivalents, due primarily to the $11.6 million of cash provided by operations and the $2.3 million of cash received from the exercise of stock options and proceeds from our employee stock purchase plan, reduced by the $4.4 million of cash used for capital expenditures;

• $2.0 million increase in net accounts receivable, as new accounts exceeded collections of outstanding balances for the nine months ended September 30, 2014;

• $2.1 million increase in deferred costs, current, for expenses related to increased implementation resources and commission payments for new business;

• $974,000 increase in prepaid expenses and other current assets due primarily to prepaid service contracts;

• $300,000 increase in accounts payable, primarily due to timing of payments;

• $2.1 million increase in accrued compensation and benefits, due primarily to payroll timing;

• $1.0 million decrease in accrued expenses and other current liabilities due primarily to payments completed under a software licensing agreement; and

• $626,000 increase in deferred revenue, current, due to new business for the nine months ended September 30, 2014.

Net Cash Flows from Operating Activities

Net cash provided by operating activities was $11.6 million for the nine months ended September 30, 2014 compared to $16.1 million for the same period in 2013. The increase in net income, the changes in non-cash expenses, including increased depreciation and stock-based compensation, and the changes in our working capital accounts, including those discussed above, resulted in the overall decrease in net cash provided by operations.

16

Net Cash Flows from Investing Activities

Net cash used in investing activities was $4.4 million and $5.0 million for the nine months ended September 30, 2014 and 2013, respectively, all for capital expenditures. Our capital expenditures are for supporting our business growth and existing customer base, as well as for our internal use such as equipment for our employees.

Net Cash Flows from Financing Activities

Net cash provided by financing activities was $2.3 million and $3.7 million for the nine months ended September 30, 2014 and 2013, respectively, all related to the exercise of stock options and our employee stock purchase plan.

Credit Facility

We have a revolving credit agreement with JPMorgan Chase Bank, N.A. that will mature on September 30, 2016. The revolving credit agreement provides for a $20 million revolving credit facility that we may draw upon from time to time, subject to certain terms and conditions. There were no borrowings outstanding at September 30, 2014 and we were in compliance with all covenants under the revolving credit agreement as of that date.

Adequacy of Capital Resources

Our future capital requirements may vary significantly from those now planned and will depend on many factors, including the costs to develop and implement new solutions and applications, the sales and marketing resources needed to further penetrate our market and gain acceptance of new solutions and applications we develop, the expansion of our operations in the United States and internationally, the response of competitors to our solutions and applications and our use of capital for acquisitions, if any. Historically, we have experienced increases in our expenditures consistent with the growth in our operations and personnel, and we anticipate that our expenditures will continue to increase as we grow our business.

We believe our cash and cash equivalents and our cash flows from operations will be sufficient to meet our working capital and capital expenditure requirements for at least the next twelve months.

Inflation and changing prices did not have a material effect on our business during the nine months ended September 30, 2014. We do not expect that inflation or changing prices will materially affect our business in the foreseeable future.

Our results of operations and cash flows are not materially affected by fluctuations in foreign currency exchange rates.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, investments in special purpose entities or undisclosed borrowings or debt. Additionally, we are not a party to any derivative contracts or synthetic leases.

17

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Interest Rate Sensitivity Risk

For fixed rate debt, interest rate changes affect the fair value of financial instruments but do not impact earnings or cash flows. Conversely, for floating rate debt, interest rate changes generally do not affect the fair market value but do impact future earnings and cash flows, assuming other factors are held constant. The principal objectives of our investment activities are to preserve principal, provide liquidity and maximize income consistent with minimizing risk of material loss. The recorded carrying amounts of cash and cash equivalents approximate fair value due to their short maturities. We did not have any outstanding debt as of September 30, 2014. We therefore do not have any material risk to interest rate fluctuations unless we borrow under our credit facility in the future.

Foreign Currency Exchange Risk

Our results of operations and cash flows are not materially affected by fluctuations in foreign currency exchange rates.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this Quarterly Report on Form 10-Q, our management has evaluated, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934). Disclosure controls and procedures are designed to ensure that information required to be disclosed in our reports filed under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that our disclosure controls and procedures were effective as of September 30, 2014.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting during the quarter ended September 30, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

18

PART II. – OTHER INFORMATION

Item 1. Legal Proceedings

We are not currently subject to any material legal proceedings. From time to time, we may be named as a defendant in legal actions or otherwise be subject to claims arising from our normal business activities. Any such actions, even those that lack merit, could result in the expenditure of significant financial and managerial resources. We believe that we have obtained adequate insurance coverage or rights to indemnification in connection with potential legal proceedings that may arise.

Item 1A. Risk Factors

There have been no material changes in our risk factors from those disclosed under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission on February 20, 2014.

Stock-Based Compensation

NOTE D – Stock-Based Compensation

Our equity compensation plans provide for the grant of incentive and nonqualified stock options, as well as other stock-based awards including restricted stock and restricted stock units, to employees, non-employee directors and other consultants who provide services to us. Restricted stock awards result in the issuance of new shares when granted. For other stock-based awards, new shares are issued when the award is exercised, vested or released according to the terms of the agreement. In January 2014, 965,527 additional shares were reserved for future issuance under our 2010 Equity Incentive Plan. At September 30, 2014, there were approximately 2.6 million shares available for grant under approved equity compensation plans.

We recorded non-cash stock-based compensation expense of $1.3 million and $4.0 million for the three and nine months ended September 30, 2014, and $1.1 million and $3.1 million for the three and nine months ended September 30, 2013, respectively. This expense was allocated as follows (in thousands):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2014		2013		2014		2013
Cost of revenues	$	134	$	128	$	439	$	353
Operating expenses
Sales and marketing		469		378		1,423		1,106
Research and development		134		71		322		195
General and administrative		556		508		1,807		1,466
Total stock-based compensation expense	$	1,293	$	1,085	$	3,991	$	3,120

As of September 30, 2014, there was approximately $9.9 million of unrecognized stock-based compensation expense under our equity compensation plans, which is expected to be recognized on a straight line basis over a weighted average period of 2.7 years.

Stock Options

Stock options generally vest over four years and have a contractual term of seven to ten years from the date of grant. Our stock option activity was as follows:

	Options (#)			Weighted Average Exercise Price ($/share)
Outstanding at December 31, 2013		1,097,223		$	19.62
Granted		150,230			63.01
Exercised		(138,420	)		11.20
Forfeited		(12,334	)		41.36
Outstanding at September 30, 2014		1,096,699			26.38

Of the total outstanding options at September 30, 2014, 724,045 were exercisable with a weighted average exercise price of $17.68 per share. The total outstanding options had a weighted average remaining contractual life of 5.5 years.

The weighted average fair value per share of options granted during the first nine months of 2014 was $24.46 and this was estimated on the date of grant using the Black-Scholes option pricing model with the following assumptions:

Weighted-average volatility	41.8	%
Expected dividend yield	0	%
Expected life (in years)	4.2
Risk-free interest rate	1.06-1.55	%

Restricted Stock Units and Awards

Restricted stock units vest over four years and, upon vesting, the holder is entitled to receive shares of our common stock. With restricted stock awards, shares of our common stock are issued when the award is granted and the restrictions lapse over one year.

Our restricted stock units activity was as follows:

	Restricted Stock Units (#)			Weighted Average Grant Date Fair Value ($/share)
Outstanding at December 31, 2013		102,644		$	33.77
Granted		40,503			65.19
Vested and common stock issued		(28,271	)		32.77
Forfeited		(1,145	)		35.42
Outstanding at September 30, 2014		113,731			45.19

The number of restricted stock units outstanding at September 30, 2014 included 19,262 units that have vested but for which shares of common stock have not yet been issued pursuant to the terms of the agreement.

Our restricted stock awards activity was as follows:

	Restricted Stock Awards (#)			Weighted Average Grant Date Fair Value ($/share)
Outstanding at December 31, 2013		1,422		$	48.66
Restricted common stock issued		5,352			51.74
Restrictions lapsed		(3,861	)		50.79
Forfeited		(237	)		48.66
Outstanding at September 30, 2014		2,676			51.74

Employee Stock Purchase Plan

Our employee stock purchase plan allows participating employees to purchase shares of our common stock at a discount through payroll deductions. The plan is available to all employees subject to certain eligibility requirements. Participating employees may purchase common stock, on a voluntary after-tax basis, at a price that is the lower of 85% of the fair market value of one share of common stock at the beginning or end of each stock purchase period. The plan consists of two six-month offering periods, beginning on January 1 and July 1 of each calendar year. A total of 1.2 million shares of common stock are reserved for issuance under the plan.

For the offering period that began on January 1, 2014 and ended June 30, 2014, we withheld approximately $680,000 from employees participating in the plan. On June 30, 2014, approximately $672,000 of these funds was used to purchase 12,520 shares on behalf of the employees participating in the plan. The remaining funds were refunded to employees pursuant to the requirements of the plan. For the offering period that began on July 1, 2014 and will end on December 31, 2014, we have withheld approximately $358,000 as of September 30, 2014 from employees participating in the plan.

For the three and nine months ended September 30, 2014, we recorded approximately $85,000 and $286,000, respectively, of stock-based compensation expense associated with the employee stock purchase plan. The fair value was estimated based on the market price of our common stock at the beginning of each offering period and using the Black-Scholes option pricing model with the following assumptions:

Expected volatility	48.9	%
Expected dividend yield	0	%
Expected life (in years)	0.50
Risk-free interest rate	0.10	%

Accounting Policies [Abstract]

General

NOTE A – General

Business Description

We are a leading provider of cloud-based supply chain management solutions, providing prewired, proven integrations and comprehensive retail performance analytics to thousands of customers worldwide. We provide our solutions through the SPS Commerce platform, a cloud-based software suite that improves the way suppliers, retailers, distributors and other customers manage and fulfill orders. We derive the majority of our revenues from thousands of monthly recurring subscriptions from businesses that utilize our solutions.

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of SPS Commerce, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP. We have included all normal recurring adjustments considered necessary to give a fair statement of our financial position, results of operations and cash flows for the interim periods shown. Operating results for these interim periods are not necessarily indicative of the results to be expected for the full year. The December 31, 2013 condensed consolidated balance sheet data was derived from our audited financial statements at that date. For further information, refer to the consolidated financial statements and accompanying notes for the year ended December 31, 2013 included in our Annual Report on Form 10-K as filed with the Securities and Exchange Commission on February 20, 2014.

Use of Estimates

Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Significant Accounting Policies

During the nine months ended September 30, 2014, there were no material changes in our significant accounting policies. See Note A to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the Securities and Exchange Commission on February 20, 2014, for additional information regarding our significant accounting policies.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued new accounting requirements for the recognition of revenue from contracts with customers. These new requirements are effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. We are currently evaluating the impact of this guidance on our results of operations and financial position.

On October 12, 2014, we, together with our wholly owned subsidiary SPS Commerce Australia Pty Ltd, entered into and completed an asset purchase agreement with Leadtec Systems Australia Pty Ltd (“Leadtec”) and its affiliates, Advanced Barcode Solutions Pty Ltd, Scott Needham and Leading Technology Group Pty Ltd. Under the asset purchase agreement, we purchased and acquired from Leadtec substantially all of the assets used in Leadtec’s business. Leadtec is in the business of cloud-based integration solutions.

Basic net income per share has been computed using the weighted average number of shares of common stock outstanding during each period. Diluted net income per share also includes the impact of our outstanding potential common shares, including options and restricted stock units. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net income per share.

The following table presents the components of the computation of basic and diluted net income per share for the periods indicated (in thousands, except per share amounts):

	Three Months Ended September 30,				Nine Months Ended September 30,

Diluted	$	0.05	$	0.02	$	0.11	$	0.05

The effect of approximately 126,000 outstanding potential common shares was excluded from the calculation of diluted net income per share for each of the three and nine months ended September 30, 2014 because they were anti-dilutive. For each of the three and nine months ended September 30, 2013, the effect of all outstanding potential common shares was included in the calculation of diluted net income per share.

Basis of Presentation

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements include the accounts of SPS Commerce, Inc. and its subsidiaries. All intercompany accounts and transactions have been eliminated in the condensed consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, these condensed consolidated financial statements do not include all of the information and notes required by GAAP. We have included all normal recurring adjustments considered necessary to give a fair statement of our financial position, results of operations and cash flows for the interim periods shown. Operating results for these interim periods are not necessarily indicative of the results to be expected for the full year. The December 31, 2013 condensed consolidated balance sheet data was derived from our audited financial statements at that date. For further information, refer to the consolidated financial statements and accompanying notes for the year ended December 31, 2013 included in our Annual Report on Form 10-K as filed with the Securities and Exchange Commission on February 20, 2014.

Use of Estimates

Use of Estimates

Preparing financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

Significant Accounting Policies

Significant Accounting Policies

During the nine months ended September 30, 2014, there were no material changes in our significant accounting policies. See Note A to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2013, as filed with the Securities and Exchange Commission on February 20, 2014, for additional information regarding our significant accounting policies.

Recent Accounting Pronouncements

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board issued new accounting requirements for the recognition of revenue from contracts with customers. These new requirements are effective for annual reporting periods beginning after December 15, 2016, and interim periods within those annual periods. We are currently evaluating the impact of this guidance on our results of operations and financial position.

Income Tax Disclosure [Abstract]

Income Taxes

NOTE E – Income Taxes

We record our interim provision for income taxes by applying our estimated annual effective tax rate to our year-to-date pretax income and adjust the provision for discrete tax items recorded in the period. Differences between our effective tax rate and statutory tax rates are primarily due to the impact of meals and entertainment expense, employee stock purchase plan expense, as well as the federal R&D credit.

We recorded income tax expense of $532,000 and $1.2 million for the three and nine months ended September 30, 2014. We recorded income tax expense of $169,000 and $272,000 for the three and nine months ended September 30, 2013. Our provisions for income taxes included current foreign and state income tax expense, as well as deferred tax expense.

We are subject to U.S federal income tax as well as income tax in various state and international jurisdictions. We are generally subject to tax examinations for all prior years due to our net operating loss carryforwards. As of September 30, 2014, we were not under any income tax audits by tax authorities.

As of September 30, 2014 we do not have any unrecognized tax benefits. It is our practice to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. We do not expect any material changes in our unrecognized tax positions over the next 12 months.
