Synacor Delivers on First-Quarter 2017 Financial Guidance;

Achieves Milestones on Path to 3/30/300

BUFFALO, N.Y., May 10, 2017 - Synacor, Inc. (NASDAQ: SYNC), the trusted multiscreen technology and monetization partner for video, internet and communications providers, device manufacturers, governments and enterprises, today announced its financial results for the quarter ended March 31, 2017.

“We continue to see strong customer affirmation of Synacor platforms, as we renew and expand key current relationships and win new customers. And I’m pleased to announce that the new ATT.net portal is live and the phased rollout is well underway,” said Synacor CEO Himesh Bhise.

“In April, we strengthened our balance sheet with $20 million in capital from an equity offering in order to execute on our strong growth pipeline. We remain well positioned to deliver on our target of $300 million in revenue and $30 million in adjusted EBITDA in 2019,” said Bhise.  

Recent Highlights

Q1 2017 Financial Results

Revenue: For the first quarter of 2017, revenue was $26.5 million, in line with guidance, a decrease of 12% compared with the first quarter of 2016, primarily due to the anticipated year-over-year decline in desktop search revenue.

Net Income: For the first quarter of 2017, net loss was $6.7 million, compared with net loss of $1.6 million in the first quarter of 2016, reflecting continued customer-driven product development investment. Earnings per share, or EPS, was a loss of $0.21 compared with a loss of $0.05 in the first quarter of 2016.

Adjusted EBITDA: For the first quarter of 2017, adjusted earnings before interest, taxes, depreciation, and amortization (adjusted EBITDA), which excludes stock-based compensation expense, was ($3.3) million in line with guidance compared with $1.5 million for the first quarter of 2016, reflecting customer-driven product development investment.

Cash: The Company ended the first quarter of 2017 with $11.3 million in cash and cash equivalents, compared with $14.3 million at the end of the prior quarter. This excludes the $20 million raised in April from the equity offering, net of underwriting costs and commissions.

Non-GAAP Financial Measures

The Company uses certain non-GAAP financial measures in this release. Generally, a non-GAAP financial measure is a numerical measure of a company's performance, financial position or cash flows that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with generally accepted accounting principles (GAAP).

We report adjusted EBITDA because it is a key measure used by our management and Board of Directors to understand and evaluate our core operating performance and trends, to prepare and approve our annual budget and to develop short- and long-term operational plans. In particular, the exclusion of certain expenses in calculating adjusted EBITDA can provide a useful measure for period-to-period comparisons of our core business. Accordingly, we believe that adjusted EBITDA provides useful information to investors and others in understanding and evaluating our operating results in the same manner as our management and Board of Directors.

For a reconciliation of adjusted EBITDA to net income (loss), the most directly comparable financial measure calculated and presented in accordance with GAAP, please refer to the table “Reconciliation of GAAP to Non-GAAP Measures” in this press release.
