EBITDA represents earnings (or losses) before interest, income taxes, depreciation, and amortization. Adjusted EBITDA further eliminates the effect of stock-based compensation, merger integration related expenses and impairment of goodwill and identifiable intangible assets.

Free cash flow is defined as net cash provided by (used in) operating activities less capital expenditures.

Non-GAAP net income (loss), EBITDA, Adjusted EBITDA and free cash flow are used by management, analysts, investors and other interested parties in evaluating our operating performance compared to that of other companies in our industry. The calculation of non-GAAP net income (loss) eliminates the effect of stock-based compensation, amortization of intangible assets and impairment of goodwill and intangible assets and EBITDA and Adjusted EBITDA further eliminates the effect of financing, income taxes, the accounting effects of capital spending and certain other merger related expenses, which items may vary from different companies for reasons unrelated to overall operating performance. Free cash flow is used as a supplemental financial measure in our evaluation of liquidity and financial strength.

PFSweb believes these non-GAAP measures provide useful information to both management and investors by excluding certain expenses that may not be indicative of its core operating results. These measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. These non-GAAP measures included in this press release have been reconciled to the GAAP results in the attached tables.

Merchandise Sales

Merchandise sales represent the estimated value of all fulfillment activity that flows through PFSweb including whether or not PFSweb is the seller of the merchandise or records the full amount of such sales on its financial statements, excluding service fee revenues that PFSweb might recognize for the underlying sales transactions.
