Forward-Looking Statements

This Form 8-K, including Exhibit 99.1 attached hereto, may contain forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. Such forward-looking statements are characterized by future or conditional verbs such as “may,” “will,” “expect,” “intend,” “anticipate,” “believe,” “estimate” and “continue” or similar words, including statements regarding the Company’s ability to consummate the Merger. You should read statements that contain these words carefully because they discuss future expectations and plans, which contain projections of future results of operations or financial condition or state other forward-looking information. Such statements are only predictions and the Company’s actual results may differ materially from those anticipated in these forward-looking statements. Such forward-looking statements are subject to risks and uncertainties, many of which are beyond the Company’s control, which could cause the Company’s actual results to differ materially from those expressed in or implied by these statements.

By their nature, forward-looking statements address matters that are subject to risks and uncertainties. A variety of factors could cause actual events and results to differ materially from those expressed in or contemplated by the forward-looking statements. Risk factors affecting the Company are discussed in detail in the Company’s filings with the U.S. Securities and Exchange Commission (“SEC”). The Company undertakes no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future events or otherwise, except to the extent required by applicable laws. These forward-looking statements include, but are not limited to, statements regarding the proposed merger between the Company and RTB Digital, Inc. (collectively, the “Parties”), the expected closing of the proposed Merger and the timing thereof and as adjusted descriptions of the post-transaction company and its operations, strategies and plans, including the management team and board of directors of the Company following the consummation of the Merger. There are a number of risks and uncertainties that could cause actual results to differ materially from the forward-looking statements included in the Form 8-K and the Press Release. These include: the risk that the Parties’ businesses will not be integrated successfully and the risk that cost savings, synergies and growth from the proposed Merger may not be fully realized or may take longer to realize than expected; the possibility that stockholders of the Company may not approve the issuance of new shares of Company common stock in the Merger or that stockholders of the Company may not approve the Merger; the risk that a condition to the closing of the Merger may not be satisfied, that either party may terminate the definitive agreement or that the closing of the Merger might be delayed or may not occur at all; potential adverse reactions or changes to business or employee relationships, including those resulting from the announcement or completion of the Merger; the risk that the Parties do not receive regulatory or other approvals of the Merger; the occurrence of any other event, change, or other circumstances that could give rise to the termination of the Merger agreement or changes to the transactions; the risk that changes in the Company’s capital structure and governance could have adverse effects on the market value of its securities; the ability of the Parties to retain customers and retain and hire key personnel and maintain relationships with their suppliers and customers and on the Parties’ operating results and business generally; the risk the Merger could distract the respective managements of the Parties from ongoing business operations or cause the Parties to incur substantial costs; impacts on the Parties’ plans for value creation and strategic advantages, market size and growth opportunities, regulatory conditions, competitive position and the interest of other corporations in similar business strategies, technological and market trends, future financial condition and performance and expected financial impacts of the Merger; the risk that the Parties may be unable to reduce expenses or access financing or liquidity; the impact of any economic downturn; the risk of changes in governmental regulations or enforcement practices; and other important factors that could cause actual results to differ materially from those projected and those discussed under risk factors in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 and other filings filed with the SEC (including its Current Reports on Form 8-K and Quarterly Reports on Form 10-Q). Forward-looking statements speak only as of the date they are made. The Company does not assume any obligation to update forward-looking statements as circumstances change. The Company gives no assurance that it will achieve its expectations.

Additional Information and Where to Find It

The Company intends to file with the SEC a registration statement on Form S-4 (as may be amended, the “Registration Statement”), which will include a preliminary proxy statement in connection with the proposed Merger pursuant to a definitive merger agreement. The definitive proxy statement and other relevant documents will be mailed to stockholders of the Company as of a record date to be established for voting on the proposed Merger. STOCKHOLDERS OF THE COMPANY AND OTHER INTERESTED PARTIES ARE URGED TO READ, WHEN AVAILABLE, THE PRELIMINARY PROXY STATEMENT, AND AMENDMENTS THERETO, AND THE DEFINITIVE PROXY STATEMENT IN CONNECTION WITH THE COMPANY’S SOLICITATION OF PROXIES FOR THE SPECIAL MEETING OF ITS STOCKHOLDERS TO BE HELD TO APPROVE THE PROPOSED MERGER BECAUSE THESE DOCUMENTS WILL CONTAIN IMPORTANT INFORMATION ABOUT THE PARTIES AND THE PROPOSED MERGER. Stockholders will also be able to obtain copies of the Registration Statement and the proxy statement/prospectus, without charge, once available, on the SEC’s website at www.sec.gov.

NEITHER THE SEC NOR ANY STATE SECURITIES REGULATORY AGENCY HAS APPROVED OR DISAPPROVED THE MERGER DESCRIBED HEREIN, PASSED UPON THE MERITS OR FAIRNESS OF THE TRANSACTIONS OR ANY RELATED TRANSACTIONS OR PASSED UPON THE ADEQUACY OR ACCURACY OF THE DISCLOSURE IN THIS FORM 8-K. ANY REPRESENTATION TO THE CONTRARY CONSTITUTES A CRIMINAL OFFENSE.

Each of the Parties, their respective directors and executive officers and other employees may be considered participants in the solicitation of proxies from the stockholders of each of the Parties with respect to the Merger transaction. Information about the directors and executive officers of the Company is set forth in its Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

These documents can be obtained free of charge from the sources indicated above.
