B. Riley Financial to Acquire United Online for $11.00 per share,

Announces Equity Offering and Earnings Guidance

LOS ANGELES, CA – May 4, 2016 – B. Riley Financial, Inc. (NASDAQ: RILY), a diversified provider of financial and business advisory services, today announced that it has signed a definitive agreement and plan of merger to acquire United Online, Inc. (NASDAQ: UNTD), a leading provider of consumer services and products over the Internet, for $11.00 per share, or approximately $170 million in aggregate merger consideration. The consideration represents approximately $48 million in cash consideration from B. Riley Financial after taking into account the projected United Online cash balance at closing.

United Online’s Communications segment features the Internet access brands, NetZero and Juno, which offer a range of high-quality, low-priced dial-up and DSL Internet access services. In 2015, United Online’s Communications segment generated approximately $90 million in revenue and $29.1 million of adjusted EBITDA. Additionally, United Online’s Unallocated Corporate segment expenses resulted in an adjusted EBITDA loss in 2015 of $(14.7) million.

“The acquisition of United Online is consistent with our long-term strategy of expanding and diversifying our business through opportunistic acquisitions,” said Bryant Riley, Chairman and CEO of B. Riley Financial. “We have spent the last few years strategically assembling professionals which have created a truly diversified financial services offering. With Great American’s expertise in asset valuation and disposition services, B. Riley’s investment banking, capital markets and restructuring expertise, combined with our wealth and asset management services, we have put ourselves in the unique position to capitalize on investment opportunities like United Online.”

“Given our longstanding history with and knowledge of United Online’s business, we understand that United Online is in a mature market. While factoring this in, we believe this acquisition presents our shareholders with a compelling risk-adjusted financial return that capitalizes on United Online’s predictable cash flow. United Online’s long standing employee base has done a fantastic job of managing the business in a declining business environment to maximize cash flow. We look to continue to capitalize on their prudent management.”

Mr. Riley continued, “We are also providing guidance regarding Adjusted EBITDA of $9 to $13 million for the year-to-date period through July 2016. As our investors have come to understand, our financial performance from quarter to quarter can vary significantly due to the episodic nature of some of our

underlying businesses. Several transactions this year are expected to conclude in June or July which impact the timing of our recognition of such revenues. As such, we have taken the unusual approach to give guidance for a period that extends through July.”

As separately announced, B. Riley Financial has launched today a $20 million follow-on public offering of common stock, with significant participation expected by senior management and members of the board of directors. In addition, the Company anticipates entering into a senior secured credit facility, collateralized by the assets of United Online to fund a portion of the merger consideration.

The merger is anticipated to close in the third quarter of 2016, pending satisfaction of customary closing conditions, including a favorable vote by stockholders of United Online.

Note: Certain of the information set forth herein, including adjusted EBITDA, may be considered non-GAAP financial measures. B. Riley Financial believes this information is useful to investors because it provides a basis for measuring the company’s available capital resources, the operating performance of its business and its cash flow, excluding depreciation and amortization, stock-based compensation, restructuring and other exit costs, litigation or dispute settlement costs, transaction-related costs, and net income attributable to non-controlling interests that would normally be included in the most directly comparable measures calculated and presented in accordance with Generally Accepted Accounting Principles (“GAAP”). In addition, the company’s management uses these non-GAAP financial measures along with the most directly comparable GAAP financial measures in evaluating the company’s operating performance, capital resources and cash flow. Non-GAAP financial measures should not be considered in isolation from, or as a substitute for, financial information presented in compliance with GAAP, and non-financial measures as reported by the company may not be comparable to similarly titled amounts reported by other companies. The non-GAAP measures are described above and are reconciled to the corresponding GAAP measure in the unaudited condensed consolidated financial statements portion of this release under the headings “Adjusted EBITDA and Proforma EBITDA Reconciliation.”
