Zix Reports Fourth Quarter and Full Year 2018 Financial Results

Higher Cloud Based Encryption Adoption and Increasing Attach Rates Drive Record Fourth Quarter New First Year Orders, Double-Digit Revenue Growth and Record Adjusted EBITDA

Zix Corporation (Zix) ZIXI, a leader in email security, today announced financial results for the fourth quarter and full year ended December 31, 2018.

Fourth Quarter 2018 Financial Highlights (results compared to the same year-ago quarter)

Revenue increased 10% to a record $18.4 million.
Annual recurring revenue (ARR) increased 13% to a record $75.8 million.
New First Year Orders (NFYO) increased 23% to $3.1 million.
Total orders increased 21% to $17.6 million.
GAAP net income increased from ($12.9) million to $9.2 million.*
GAAP fully diluted earnings per share increased from ($0.24) to $0.17.*
Non-GAAP fully diluted earnings per share increased from ($0.20) to $0.22.
Non-GAAP fully diluted earnings per share excluding deferred tax (benefit) expense increased 1% to $0.09.
Cash flow from operations increased 16% to $4.9 million.
Adjusted EBITDA increased 14% to a record $5.6 million, representing an adjusted EBITDA margin of 30.2%.
The company ended the quarter with $27.1 million in cash.

* The income of $9.2 million (or $0.17 per fully diluted share) was largely the result of a $7.8 million reduction in the company's deferred tax valuation allowance based on current and expected future profitability. The net loss of $12.9 million (or $0.24 per fully diluted share) in Q4 2017 was largely a result of a one-time non-cash charge of $12.5 million due to the future effect of the lower U.S. corporate income tax rate resulting from the 2017 tax reform legislation.

Management Commentary

"With revenue up 10% to a record $18.4 million and adjusted EBITDA up 14% to a record level of $5.6 million, representing an adjusted EBITDA margin of 30.2%, the fourth quarter of 2018 topped off another strong year for the company," said David Wagner, Zix's Chief Executive Officer. "Our commitment to profitable growth continues to inform our growth strategy and is shaping our journey to become one of the leading cloud-based email security providers. Building off of the success we have been experiencing with ZixProtect and ZixArchive, earlier this year we announced major enhancements to ZixArchive, significantly expanding our archiving capabilities. Our work in 2018 also focused on strengthening our distribution capabilities. We expanded our managed service provider (MSP) program, added dozens of G-Suite resellers and reduced our reliance on OEM partnerships in favor of partners more aligned with our cloud-based offerings. Earlier this quarter we launched ZixSuite, a cloud-based business communications security and compliance solution that combines advanced threat protection, business email continuity, email encryption, email DLP and unified archiving, all managed from a centralized interface. We believe the end result has been the successful alignment of our business to the cloud—and a really strong foundation from which to further build with the acquisition of AppRiver that closed earlier this month. Today, we are a much stronger business that is even better positioned to help our customers. We're also a business with much greater scale, and with significant cost synergies, cross-selling opportunities, and market tailwinds working in our favor."

Zix's Chief Financial Officer Dave Rockvam added: "Q4 was a success in many ways, with record revenue, record ACV, a return to double-digit topline growth, and New First Year Orders growth of more than 20% for the third consecutive quarter. This strong performance was once again driven by the success of our sales teams in attracting new customers and selling additional solutions into our growing installed base. Our progress in driving stronger topline growth coupled with our continued success in managing our costs enabled us to achieve a 30.2% adjusted EBITDA margin during the quarter—the highest level achieved since Dave and I joined Zix in 2016. Overall, our results for the quarter and full year demonstrate that the strategy we laid out three years ago to drive strong returns for our shareholders is really starting to bear fruit. With our recent transformational acquisition of AppRiver, we look to extend this success in a much more impactful way by leveraging our newfound scale, cost synergies, expanded customer base, and complementary solutions."

Recent Operational Highlights

Acquired AppRiver, a leading cloud-based cybersecurity solutions provider, creating significant scale and accelerating growth, attractive cross-selling opportunities, and a strengthened position in the cloud-based email security market.
Expanded unified archiving solution ZixArchive beyond email to include 48 new business communication channels, including social media, instant message, mobile, web, audio and video.
Launched ZixSuite, a cloud-based business communications security and compliance solution that combines advanced threat protection, business email continuity, email encryption, email DLP and unified archiving, all managed from a centralized interface.

2018 Operational Highlights

Acquired Seattle-based Erado to expand unified archiving, eDiscovery, and compliance solution.
Strengthened the Zix managed service provider program by expanding offerings to include email threat protection and email archiving and providing additional partner value with flexible billing, rapid deployment and a centralized management console for administration of Zix solutions.
Launched ZixEncrypt EMS featuring a new, on-premise portal capability, a broader range of delivery options (including SMIME) and meaningfully improved the EMS user experience.
Strengthened the Zix partner program with addition of top Google partners, which will resell the full suite of Zix solutions, including ZixArchive^®, ZixEncrypt^® and ZixProtect^®.

Zix management is also expecting revenue of approximately $47 million to $50 million with a 24% adjusted EBITDA margin in the fourth quarter of 2019.

The company's targeted earnings per share both on a GAAP and non-GAAP adjusted basis include the addition of approximately 16.6 million common shares equivalents associated with the $100 million preferred stock investment by True Wind Capital, which occurred simultaneously with the acquisition of AppRiver.

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 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.
