Management Commentary
“Following successful launches in the prior quarter, ZixProtect and ZixArchive continued to perform well ahead of our internal plan,” saidDave Wagner, Zix’s Chief Executive Officer. “Our early traction with these solutions has validated the timely rollout of our bundled product suite, when many customers are increasingly seeking more value from fewer vendors. During the quarter, several partner-based accounts fell behind their deployment schedules, and therefore their contributions could not be included in our third quarter revenue results. We also experienced weakness in our customer renewals which was largely driven by customer M&A activity. Our strategic decision to enter into the advanced threat protection and email archiving markets while also strengthening our hosted solution better positions us to mitigate these pressures and drive greater long-term value for our customers.”
Zix’s Chief Financial OfficerDave Rockvam added: “New first year orders during the third quarter increased 11.4% and experienced a solid boost due to the recent introductions of ZixProtect and ZixArchive. We also experienced solid year-over-year revenue growth and achieved record revenue for the 14th quarter in a row. Additionally, we achieved ournon-GAAP fully diluted earnings per share guidance of $0.07. Complementing these healthy results was our return to achieving a 28% adjusted


EBITDA margin, which we forecasted in the prior quarter and which is consistent with our long-term model. Looking ahead, we expect similar strong bottom-line results but expect a slight impact to our previously forecasted topline.”
Wagner continued: “We are driven by innovation and our commitment to our customers to provide the very best email security solution possible, which is why we acquired Entelligence Messaging Server (EMS) during the third quarter. The EMS technology will be integrated into our ZixEncrypt roadmap to enhance ourend-to-end encryption capabilities, as well as give us more delivery and deployment options and FIPS validated cryptography, which will give us an added edge when marketing to new customers and upselling existing ones. When combined with the portfolio expansion from our Greenview Data acquisition earlier in the year, we believe our enhanced product suite positions us as not only the gold standard in email encryption but in the broader email security market as well.”
Third Quarter 2017 Operational Highlights
| • | | Acquired Entelligence Messaging Server business to strengthen Zix’s industry-leading email encryption solutions |
| • | | Entered into astrategic partnership with Digital Guardian, a next-generation data protection platform, to bring togetherbest-in-class email encryption with enterprise data loss prevention |

ZIX CORPORATION
NOTES TO RECONCILIATION OF GAAP TONON-GAAP FINANCIAL MEASURES
USE OFNON-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 theseNon-GAAP measures provide investors with a more informed baseline for modeling the Company’s future financial performance. Management uses theseNon-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. TheseNon-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 certainNon-GAAP financial measures, together with an explanation of why management uses these measures and why management believes that theseNon-GAAP financial measures are useful to investors. In addition, in our earnings release we have provided tables to reconcile theNon-GAAP financial measures utilized to GAAP financial measures.
ADJUSTEDNON-GAAP MEASURES
OurNon-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 fornon-cash stock-based compensation expense, and strategic consulting and litigation costs to deriveNon-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 adjustedNon-GAAP measures to GAAP Gross profit, Operating income, Net income, Net income per share - diluted and EBITDA.
Our forward-looking adjustedNon-GAAP earnings per share information consistently excludesnon-cash stock-based compensation expense. Additionally, the adjustedNon-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 toNon-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 (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 ofnon-cash stock-based compensation charges on our operating results.
(B) Strategic consulting 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) TheNon-GAAP adjustment to the tax provision represents thenon-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.
