"Financially, we delivered 18% total revenue growth, 17% ARR growth and 7% adjusted gross profit dollar growth, while generating $14.7 million in cash flow from operations. Operationally, we continue to accelerate the adoption of our Secure Cloud platform which is further improving partner/customer experiences and allowing us to layer on more services. CloudAlly is continuing to perform exceedingly well, reflecting cloud backup's increasingly critical role within a secure modern workplace. We launched Secure Cloud into the German market this quarter, demonstrating both our commitment to the channel and execution on our international expansion plan. Looking ahead, Zix remains well positioned to capitalize on secular market trends of cloud adoption and ensuring that hybrid work environments are productive, secure, compliant and resilient."

Zix's Chief Financial Officer Dave Rockvam commented: "The second quarter again demonstrated our ability to continue driving profitable growth. In addition to robust revenue and ARR performances and strong cash flow generation, we delivered a meaningful increase in gross margin dollars in the period, highlighting our success in layering on organic, higher-margin products. Our cloud momentum has us on track to realize our goals for 2021, including revenue growth of 16% and Adjusted EBITDA of approximately $56.0 million."

Financial Outlook

Zix provides guidance based on current market conditions and expectations.

For the third quarter of 2021, the company forecasts revenue to range between $64.0 million and $64.4 million.

The company forecasts adjusted EBITDA to be approximately 22% of forecast revenue for Q3 2021.

Forward-Looking Statements

As more fully described in Zix's Annual Report on Form 10-K for the year ended December 31, 2020, which was filed with the SEC on March 5, 2021, the company has been actively monitoring the COVID-19 situation and its impact on both the company and the world in which we operate. The impact of COVID-19 and unprecedented measures to prevent its spread are affecting our business in various ways such as causing volatility in demand for our products, changes in customer behavior, including their spending and payment patterns, disruptions in the operations of our third-party suppliers and business partners, labor market conditions and limitations on our employees' and partners ability to work and travel. We expect the ultimate significance of the impact of the foregoing on our financial and operational results will be dictated by the length of time that these circumstances continue, which will depend on the currently unknowable extent and duration of the COVID-19 pandemic, or any variants thereof, and governmental and public actions taken in response. These factors also make it more challenging for management to estimate the future performance of our business, particularly over the near term.

Statements in this release that are not purely historical facts or that necessarily depend upon future events, including statements about forecasts of sales, revenue, annual recurring revenue, EBITDA, EBITDA margin, earnings or earnings per share, potential benefits of acquisitions and strategic relationships, or other statements about anticipations, beliefs, expectations, hopes, intentions or strategies for the future, may be forward-looking statements within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Readers are cautioned not to place undue reliance on forward-looking statements. All forward-looking statements are based upon information available to Zix on the date this release was issued. Zix undertakes no obligation to publicly update or revise any forward-looking statements, whether as a result of new information, future events or otherwise. Any forward-looking statements involve risks and uncertainties that could cause actual events or results to differ materially from the events or results described in the forward-looking statements, including but not limited to, risks or uncertainties related to the completion and integration of acquisitions, the effects of our debt and equity financing transactions, year-end adjustments to previously reported preliminary unaudited financial information, market acceptance of both existing and new Zix solutions, changing market dynamics resulting from technological change, innovation and continuing customer migration to the cloud, changes in the competitive ecosystem, how privacy and data security laws may affect demand for Zix data protection solutions, and business disruptions, uncertainty and market instability stemming from the COVID-19 pandemic and governmental actions related thereto. Zix may not succeed in addressing these and other risks. Further information regarding factors that could affect Zix's business and its financial and other results can be found in the risk factors section of Zix's most recent annual report on Form 10-K and quarterly report on Form 10-Q, each as filed with the Securities and Exchange Commission, as those risk factors may be supplemented in subsequent filings.

We monitor ARR as an operating metric, which we define as the aggregate annualized contract value attributable to recurring revenue contracts as of the end of the applicable reporting period. We calculate ARR by determining the annual or monthly revenue of subscription agreements that are active as of the end of the applicable period and multiplying by 1 or 12. We monitor this metric to aid in determining to what extent individual customer relationships, considered in the aggregate, are growing or declining in financial magnitude. ARR is an operating metric derived as of the date of determination, and should be viewed independently of revenue, unearned revenue and any other GAAP financial measure over any period.

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 excluding deferred tax (benefit) expense, Net income per share - diluted, Net income per share - diluted excluding deferred tax (benefit) expense, and EBITDA for non-cash stock-based compensation expense, and strategic consulting and litigation costs 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.

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 litigation expenses and non-recurring items that impact our ongoing business. See items (A) through (E) below for further information on the current quarter's reconciling items.

Items (A) through (F) 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 excluding deferred tax (benefit) expense," "Net income per share - diluted," "Net income per share excluding deferred tax (benefit) expense- diluted," and "EBITDA" and correspond to the categories explained in further detail below under (A) through (F).

(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) Strategic consulting, acquisition integration and litigation costs. See item (2) on previous page. The Company's management excludes certain board-directed consulting costs and litigation expenses when evaluating its ongoing performance and/or predicting its earnings trends and therefore excludes these charges on our adjusted operating results.

(C) Intangible amortization costs. See item (3) on previous page. The Company's management excludes amortization expenses associated with the acquisition of intangible assets when evaluating its ongoing performance and/or predicting its earnings trends and therefore excludes these charges on our adjusted operating results.

(D) Corporate separation payment relating to employment termination benefits agreement. See item (4) on previous page. 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.

(E) Deferred tax expense 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.

(F) EBITDA represents earnings before interest, taxes, depreciation and amortization. Adjusted EBITDA adds back stock-based compensation charges and litigation expenses.
