This presentation includes Non-GAAP measures. Our Non-GAAP measures are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read only in conjunction with our consolidated financial statements prepared in accordance with GAAP. For a detailed explanation of the adjustments made to comparable GAAP measures, the reasons why management uses these measures, the usefulness of these measures and the material limitations of these measures, see Notes to Reconcilation of GAAP to Non-GAAP Financial Measures on the next page.
ZIX CORPORATION
NOTES TO RECONCILIATION OF GAAP TO NON-GAAP FINANCIAL MEASURES
USE OF NON-GAAP FINANCIAL INFORMATION
The Company occasionally utilizes financial measures and terms not calculated in accordance with generally accepted accounting principles in the United States (“GAAP”) in order to provide investors with an alternative method for assessing our operating results in a manner that enables investors to more thoroughly evaluate our current performance as compared to past performance. We also believe these Non-GAAP measures provide investors with a more informed baseline for modeling the Company’s future financial performance. Management uses these Non-GAAP financial measures to make operational and investment decisions, to evaluate the Company’s performance, to forecast and to determine compensation. Further, management utilizes these performance measures for purposes of comparison with its business plan and individual operating budgets and allocation of resources. We believe that our investors should have access to, and that we are obligated to provide, the same set of tools that we use in analyzing our results. These Non-GAAP 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. We have provided definitions below for certain Non-GAAP financial measures, together with an explanation of why management uses these measures and why management believes that these Non-GAAP financial measures are useful to investors. In addition, in our earnings release we have provided tables to reconcile the Non-GAAP financial measures utilized to GAAP financial measures.
ADJUSTED NON-GAAP MEASURES
Our Non-GAAP measures adjust GAAP Cost of revenue, Gross profit, Research and development expense, Selling and marketing expense, General and administrative expense, Operating income, Net income, Net income per share - diluted, and EBITDA for non-cash stock-based compensation expense, and non-recurring litigation expense to derive Non-GAAP adjusted Cost of revenue, adjusted Gross profit, adjusted Research and development expense, adjusted Selling and marketing expense, adjusted General and administrative expense, adjusted Operating income, adjusted Net income, adjusted Net income per share - diluted and adjusted EBITDA. We provide a reconciliation of these adjusted Non-GAAP measures to GAAP Gross profit, Operating income, Net income, Net income per share - diluted and EBITDA.
We do not provide a reconciliation of forward-looking adjusted Non-GAAP earnings per share to GAAP earnings per share. Our forward-looking adjusted Non-GAAP earnings per share information consistently excludes non-cash stock-based compensation expense. Additionally, the adjusted Non-GAAP earnings per share will consistently exclude non-recurring items that impact our ongoing business. See items (A) through (C) below for further information on the current quarter’s reconciling items.
Items (A) through (D) on the “Reconciliation of GAAP to Non-GAAP Financial Measures” table are listed to the right of certain categories under “Gross profit,” “Operating income,” “Net income,” “Net income per share - diluted” and “EBITDA” and correspond to the categories explained in further detail below under (A) through (D).
(A) Non-cash stock-based compensation charges relating to stock option grants, restricted stock, and restricted stock units awarded to and accounted for in accordance with Share-Based Payment accounting guidance. See (1) on previous page for breakdown of stock-based compensation. Because of varying valuation methodologies, subjective assumptions and varying award types, the Company believes that the exclusion of stock-based compensation charges provides for more accurate comparisons to our peer companies and for a more accurate comparison of our financial results to previous periods. Additionally, the Company believes it is useful to investors to understand the specific impact of non-cash stock-based compensation charges on our operating results.
(B) Non-recurring litigation costs. See item (2) on previous page for breakdown of non-recurring litigation costs. The Company’s management excludes these costs when evaluating its ongoing performance and/or predicting its earnings trends and therefore excludes these charges on our adjusted operating results.
(C) The Non-GAAP adjustment to the tax provision represents the non-cash tax expense included in the GAAP tax provision, including the current period utilization of deferred tax assets created in previous periods. The remaining provision for income taxes represents expected cash taxes to be paid.
(D) EBITDA represents earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA adds back stock-based compensation charges and non-recurring litigation expenses.
