NOTE A – General Business Description We are a leading provider of on-demand supply chain management solutions and the Retail Universe community, providing integration, collaboration, connectivity, visibility and data analytics to thousands of customers worldwide. We provide our solutions through SPSCommerce.net, a hosted software suite that improves the way suppliers, retailers, distributors and other customers manage and fulfill orders. We deliver our solutions to our customers over the Internet using a Software-as-a-Service model and 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 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 footnotes 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, 2011 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, 2011 included in our Annual Report on Form 10-K as filed with the Securities and Exchange Commission on March 9, 2012. 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, 2012, 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, 2011, as filed with the Securities and Exchange Commission on March 9, 2012, for additional information regarding our significant accounting policies. Recent Accounting Pronouncements We have evaluated all recent accounting pronouncements and believe that none of them will have a material effect on our consolidated financial statements.

NOTE B – Business Acquisition On August 6, 2012, we entered into an asset purchase agreement with Edifice Information Management Systems, Inc. (“Edifice”), a privately-held information services company specializing in the collection, analysis and distribution of point-of-sale data used by retailers and suppliers to improve their supply chain efficiencies. We completed the asset purchase on August 7, 2012. Under the asset purchase agreement, we purchased and acquired substantially all of the assets of Edifice for $26.3 million in cash and 347,852 shares of our common stock. We also assumed certain liabilities of Edifice. This acquisition allows us to expand our point-of-sale analytic offerings, expand our base of recurring revenue customers and add suppliers to our network.   Purchase Price Allocation We accounted for the acquisition as a business combination. We allocated the purchase price to the tangible and identifiable intangible assets acquired and liabilities assumed based on their estimated fair values as of the acquisition date. We engaged an independent third-party valuation firm to assist us in the determination of the value of the purchased intangible assets. The excess of the purchase price over the fair value of net tangible and identifiable intangible assets acquired was recorded as goodwill. Goodwill is attributed to a trained workforce and other buyer-specific value resulting from expected synergies, including long-term cost savings, which are not included in the fair values of assets. Goodwill will not be amortized; however it is deductible for tax purposes. Although we believe the purchase price allocation is substantially complete, it is considered preliminary and the finalization of the valuation of the net tangible and intangible assets acquired and liabilities assumed could result in a future adjustment to the purchase price allocation. The purchase price consisted of the following (in thousands):   <table cellspacing="0" cellpadding="0" width="68%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="88%"> </td> <td valign="bottom" width="6%"> </td> <td> </td> <td> </td> <td> </td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> Cash </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">26,275</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> SPS Commerce common stock </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">11,396</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> </td> <td valign="bottom"> </td> <td valign="bottom">$</td> <td valign="bottom" align="right">37,671</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr style="font-size:1px"> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom">   </td> <td valign="bottom">   </td> <td> </td> </tr>  </table> We borrowed $11.0 million under our existing line of credit to fund a portion of the cash paid for the acquisition. The number of shares of our common stock issued for the acquisition was 347,852 shares as calculated according to the terms of the purchase agreement. The fair value of the shares issued was determined using the closing price of our common stock on August 6, 2012.

NOTE D – 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. In connection with the acquisition of Edifice (see Note B), we borrowed $11.0 million under our line of credit to fund a portion of the cash paid for the acquisition. On September 11, 2012, this debt was repaid in full with a portion of the proceeds received from our public offering of common stock on that date (see Note F). There were no borrowings outstanding at September 30, 2012 and we were in compliance with all covenants under the revolving credit agreement as of that date.

NOTE E – Commitments and Contingencies Operating Leases On February 14, 2012, we executed a new lease agreement for our current headquarters location which commences on November 1, 2012 and expires on April 30, 2020. The lease includes additional square footage upon commencement, an automatic expansion of space on or about September 1, 2013, a right of first offer to lease certain additional space, and two options to extend the term of the lease for three years at a market rate determined in accordance with the lease. We will also have a rent holiday from November 2012 to October 2013 which will be incorporated into our deferred rent calculation upon commencement of the lease. In connection with this new lease, we delivered to the landlord cash or an irrevocable letter of credit for approximately $172,000, subject to increase based on square footage expansion, as security for performance of our obligations under the lease.

NOTE F – Stockholders’ Equity In connection with the acquisition of Edifice (see Note B), we issued 347,852 shares of our common stock. The fair value of the shares issued was determined using the closing price of our common stock on August 6, 2012. On September 11, 2012, we completed a public stock offering where we issued and sold 1,840,000 shares of common stock, including 240,000 shares sold pursuant to the exercise in full of the underwriters’ over-allotment option, at a price to the public of $33.50 per share. We received net proceeds of approximately $57.8 million from this offering after payment of approximately $3.8 million of underwriting discounts and commissions and legal, accounting and other fees incurred in connection with the offering.

NOTE G – Stock-Based Compensation Our equity compensation plans provide for the grant of incentive and nonqualified stock options, as well as other stock-based awards, to employees, non-employee directors and other consultants who provide services to us. Stock options generally vest over four years and have a contractual term of seven to ten years from the date of grant. At September 30, 2012, there were approximately 1.1 million shares available for grant under approved equity compensation plans. We recorded stock-based compensation expense of $715,000 and $2.0 million for the three and nine months ended September 30, 2012, respectively. We recorded stock-based compensation expense of $487,000 and $1.3 million for the three and nine months ended September 30, 2011, respectively.

At September 30, 2012, there were 75,873 restricted stock units and 6,330 restricted stock awards outstanding. The restricted stock units vest over a four year period and the restricted stock awards vest over a one year period. Upon vesting, the holder is entitled to receive shares of our common stock. Employee Stock Purchase Plan Effective July 1, 2012, we adopted an employee stock purchase plan which 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 July 1 and January 1 of each calendar year. As of September 30, 2012, we have withheld approximately $225,000 from employees participating in the plan for the offering period that began on July 1, 2012. A total of 1.2 million shares of common stock are reserved for issuance under the plan and, at September 30, 2012, all 1.2 million shares were available for future purchases as the first offering period ends on December 31, 2012. For the three and nine months ended September 30, 2012, we recorded approximately $70,000 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 the offering period, which was $30.38 per share, and using the Black-Scholes option pricing model with the following assumptions:   <table cellspacing="0" cellpadding="0" width="68%" border="0" style="border-collapse:collapse; text-align: left" align="center">  <tr> <td width="92%"> </td> <td valign="bottom" width="6%"> </td> <td> </td> <td> </td> <td> </td> </tr>   <tr bgcolor="#cceeff"> <td valign="top"> Expected volatility </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">46.0</td> <td nowrap="nowrap" valign="bottom">% </td> </tr> <tr> <td valign="top"> Expected dividend yield </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">0</td> <td nowrap="nowrap" valign="bottom">% </td> </tr> <tr bgcolor="#cceeff"> <td valign="top"> Expected life (in years) </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">0.50</td> <td nowrap="nowrap" valign="bottom"> </td> </tr> <tr> <td valign="top"> Risk-free interest rate </td> <td valign="bottom"> </td> <td valign="bottom"> </td> <td valign="bottom" align="right">0.15</td> <td nowrap="nowrap" valign="bottom">% </td> </tr>  </table>

NOTE H – Income Taxes We recorded an income tax benefit of $124,000 and income tax expense of $329,000 for the three and nine months ended September 30, 2012, respectively. We recorded income tax expense of $81,000 and $188,000 for the three and nine months ended September 30, 2011, respectively. We record our interim provision for income taxes based on our estimated annual effective tax rate for the year. Our provisions for income taxes included current federal alternative minimum tax expense, current foreign and state income tax expense, and deferred tax expense. The decrease in income tax expense for the three months ended September 30, 2012, compared to the three months ended September 30, 2011, was primarily related to discrete net favorable items of $175,000, consisting of an increase in the state deferred tax rate related to the Edifice acquisition and provision to return adjustments for the year 2011. The increase in income tax expense for the nine months ended September 30, 2012, compared to the nine months ended September 30, 2011 was primarily related to deferred tax expense incurred in 2012 subsequent to the reversal of substantially all of the valuation allowance on our deferred tax assets in the fourth quarter of 2011. For periods prior to the fourth quarter of 2011, a full valuation allowance was recorded against all of our deferred tax assets as it was more-likely-than-not that we would not realize these deferred tax assets, largely due to our history of taxable losses since inception. Based on our assessment during the fourth quarter of 2011, we determined that it was more-likely-than-not that we would be able to realize approximately $12.8 million of our deferred tax assets, which enabled us to release a substantial portion of the valuation allowance previously recorded. This determination was based on weighing both the positive and negative evidence available including, but not limited to, our earnings history, our projected future taxable income, our business strategy and the nature of each of our deferred tax assets. We are subject to income taxes in the U.S. federal and various state and international jurisdictions. As of September 30, 2012, we are generally subject to tax examinations for all prior years due to our net operating loss carry forwards. As of September 30, 2012, 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 I – 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 and awards. Potential common shares that are anti-dilutive are excluded from the calculation of diluted net income per share.
