Item 2.02 RESULTS OF OPERATIONS AND FINANCIAL CONDITION.

On October 24, 2007, GSI Commerce, Inc. (“we” or the “Registrant”) issued a press release announcing results for its 2007 fiscal third quarter ended September 29, 2007 and certain other information. A copy of the press release is furnished as part of this report and incorporated herein by reference.

The press release (included as Exhibit 99.1) contains the non-GAAP financial measures merchandise sales, adjusted EBITDA, non-GAAP net income and free cash flow. We also discuss certain ratios that use those measures.

We use these non-GAAP financial measures for financial and operational decision making and as a means to evaluate our performance. In our opinion, these non-GAAP measures provide meaningful supplemental information regarding our performance. We believe that both management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting and analyzing future periods. These non-GAAP financial measures also facilitate management’s internal comparisons to our historical performance and liquidity as well as to the operating results of comparable companies. We believe these non-GAAP financial measures are useful to investors both because (1) they allow for greater transparency with respect to key metrics used by management in its financial and operational decision making and (2) they are used by institutional investors and the analyst community to help them analyze the health of our business.

Merchandise sales. We define merchandise sales as the retail value of all sales transactions, inclusive of freight charges and net of allowances for returns and discounts, which flow through our platform, whether we record the full amount of such transaction as a product sale or a percentage of such transaction as a service fee on our financial statements. Merchandise sales exclude the retail value of all sales transactions from partners acquired through the acquisition of Accretive Commerce as such sales do not flow through our platform. Merchandise sales do, however, include the value of freight services sold by Accretive Commerce to its partners. We consider merchandise sales to be a useful metric for management and investors because a significant portion of our sales and marketing expenses, including fulfillment and customer service labor expense, order processing costs such as credit card and bank processing fees and organizational costs such as business management, are related to the amount of sales made through our platform, whether or not we record the revenue from such sales. As a result, we use this metric as part of our revenue and expense forecasting process and for capacity planning purposes. We monitor this metric on a daily basis and consider it to be a critical measure of the health of our business.

Adjusted EBITDA. We have defined adjusted EBITDA as income from operations excluding stock-based compensation and depreciation and amortization expenses. Beginning with this release we are also excluding acquisition-related integration expenses. We consider adjusted EBITDA to be a useful metric for management and investors because it excludes certain non-cash and non-operating items. Because of varying available valuation methodologies, subjective assumptions and the variety of award types that companies can use when valuing equity awards under SFAS 123R, we believe that viewing income from operations excluding stock-based compensation expense allows investors to make meaningful comparisons between our operating performance and those of other businesses. Because we are growing rapidly and operate in an emerging and rapidly changing industry, we believe that our level of capital expenditures and consequently the level of depreciation and amortization expense relative to our revenues could be meaningfully greater today than it will be over time. As a result, we believe it is useful supplemental information to view income from operations excluding depreciation and amortization expense as it provides a potential indicator of the future operating margin potential of the business. We believe the exclusion of acquisition-related integration expenses permits evaluation and a comparison of results for on-going business operations, and it is on this basis that management internally assesses the company's performance.

Non-GAAP net income. We have defined non-GAAP net income as net income plus stock-based compensation expense and amortization of acquisition-related intangibles minus cumulative effect of change in accounting principle related to the adoption of SFAS 123R and plus/minus the provision/benefit for income taxes. Beginning with this release, we are also adding back acquisition-related integrated expenses to net income. This figure is then taxed at our current annual effective tax rate to arrive at non-GAAP net income. We believe it is useful to exclude stock-based compensation expense and acquisition-related integration expenses from non-GAAP net income for the same reasons we exclude them from adjusted EBITDA. We believe it is useful to exclude amortization of acquisition-related intangibles because in our opinion the benefits of these assets could exceed the amortization period and this supplemental view enables management and investors to measure the business without this potential effect. The gain we recorded from the cumulative effect of change in accounting principle related to the adoption of SFAS 123R is an item we view as non-recurring in nature. We believe it is useful to view net income without the benefit of this non-recurring item. We exclude the GAAP income tax provision in order to compute the non-GAAP pre-tax income. The non-GAAP pre-tax income is then taxed at our current annual effective tax rate to arrive at non-GAAP net income.

Free cash flow. We define free cash flow as net cash provided by operating activities minus cash paid for fixed assets, including capitalized software development. We consider free cash flow to be a liquidity measure that provides useful information to management and investors about the amount of cash generated by the business that, after the acquisition of property and equipment, including information technology infrastructure, can be used for strategic opportunities, including investing in the business, making strategic acquisitions and strengthening the balance sheet. Analysis of free cash flow also facilitates management’s comparisons of our operating results to the operating results of comparable companies. A limitation of using free cash flow as a means for evaluating our performance is that free cash flow reflects changes in working capital which is impacted by short-term changes in cash flow and the seasonality of our business which may not be indicative of long-term performance. Another limitation of free cash flow is that it excludes fixed assets purchased and placed in service but not paid for during the applicable period. Our management compensates for this limitation by providing information about capital expenditures on the face of the cash flow statement and in supplemental disclosures in our Forms 10-K and 10-Q.

These financial measures are not intended to be considered in isolation of, as a substitute for or superior to our GAAP financial information. The non-GAAP financial measures included in the press release and to be included the conference call have been reconciled to the nearest GAAP measure as is required under Securities and Exchange Commission rules.

As used herein, “GAAP” refers to accounting principles generally accepted in the United States.
