About Non-GAAP Financial Measures

To supplement the Company's condensed consolidated financial statements presented in accordance with GAAP, Stamps.com uses non-GAAP measures of certain components of financial performance. These non-GAAP measures include non-GAAP income from operations, non-GAAP adjusted income, non-GAAP adjusted income per fully diluted share, adjusted EBITDA and adjusted EBITDA margin. Non-GAAP adjusted income per fully diluted share is calculated as adjusted net income divided by fully diluted shares. Adjusted EBITDA margin is calculated as adjusted EBITDA divided by total revenue. Prior to the second quarter 2016, the Company referred to non-GAAP adjusted income as non-GAAP net income. Adjusted EBITDA as calculated in this release represents earnings before interest and other expense, net, interest and other income, net, income tax expense, income tax benefit, depreciation and amortization and incorporates certain items described in this release used to reconcile GAAP to non-GAAP income from operations. The presentation of non-GAAP financial measures is not intended to be considered in isolation or as a substitute for, or superior to, the financial information prepared and presented in accordance with GAAP. These non-GAAP financial measures may differ from similarly titled measures used by other companies. Reconciliation of non-GAAP financial measures included in this press release to the corresponding GAAP measures can be found in the financial tables of this earnings release.

Non-GAAP financial measures are provided to enhance investors' overall understanding of the Company's financial performance, prospects for the future and as a means to evaluate period-to-period comparisons. The Company believes the non-GAAP measures that exclude certain non-cash items including stock-based compensation expense, amortization of acquired intangibles, amortization of debt issuance costs, contingent consideration charges and income tax adjustments, and exclude certain expenses such as acquisition related expenses and litigation settlement expenses, provide meaningful supplemental information regarding financial performance by excluding certain expenses and benefits that may not be reflective of core business operating results. The Company believes that non-GAAP financial measures, when viewed with GAAP results and the accompanying reconciliation, enhance the comparability of results against prior periods and allow for greater transparency of financial results. Management uses non-GAAP financial measures in making financial, operating, compensation and planning decisions. The Company believes non-GAAP financial measures facilitate management and investors comparison of the Company's financial performance to that of prior periods as well as trend analysis over time.

Share Repurchase Timing

Share repurchases may be made from time-to-time on the open market or in negotiated transactions at the Company's discretion in compliance with Rule 10b-18 of the United States Securities and Exchange Commission.
