Business Combination Prospectus (Form 425)

Roku Vendor Email

Subject: An Important Update About Roku

Dear [Valued Partner // VENDOR NAME // INSERT CUSTOMARY GREETING],

I'm reaching out to share some exciting news about Roku's future. We just announced [INSERT LINK TO RELEASE] that Roku has agreed to combine with Fox Corporation, a diversified media and entertainment leader with scaled businesses across live sports, national and local news and both ad-supported and subscription streaming.

The streaming, advertising and AI landscapes continue to evolve, and we believe this combination is the right next step to accelerate our long-term strategy and build an even better streaming platform. Together, FOX and Roku will create a next-generation media and technology company positioned to support a broad and diverse ecosystem of streaming services and content, benefiting viewers, partners and advertisers.

The transaction is expected to close in the first half of calendar year 2027, subject to customary closing conditions. Until close, Roku and FOX will continue to operate as separate companies, and it remains business as usual for all of us at Roku. This means that we are continuing to work with you as we always have. Our partnership will continue to be critical for enabling our mutual success.

Following closing, we expect a smooth transition, including continuing to operate under the Roku brand. In the meantime, please don't hesitate to reach out with any questions.

On behalf of the Roku team, thank you for your continued support and partnership.

Sincerely,

[NAME]

No Offer or Solicitation

This communication is for informational purposes only and does not constitute, or form a part of, an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval, nor shall there be any sale of securities in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction. No offer of securities shall be made except by means of a prospectus meeting the requirements of Section 10 of the Securities Act of 1933, as amended, and otherwise in accordance with applicable law.

This document contains "forward-looking statements" within the meaning of the federal securities laws, including Section 27A of the U.S. Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These forward-looking statements are based on Parent's and the Company's current expectations, estimates and projections about the expected date of closing of the Transactions and the potential benefits thereof, their respective businesses and industries, management's beliefs and certain assumptions made by Parent and the Company, all of which are subject to change. In this context, forward-looking statements often address expected future business and financial performance and financial condition, and often contain words such as "expect," "anticipate," "intend," "plan," "believe," "could," "seek," "see," "will," "may," "would," "might," "potentially," "estimate," "continue," "target," similar expressions or the negatives of these words or other comparable terminology that convey uncertainty of future events or outcomes. All forward-looking statements by their nature address matters that involve risks and uncertainties, many of which are beyond our control and are not guarantees of future results, such as statements about the consummation of the Transactions and the anticipated benefits thereof. These and other forward-looking statements, including the failure to consummate the Transactions or to make or take any filing or other action required to consummate the transaction in a timely manner or at all, are not guarantees of future results and are subject to risks, uncertainties and assumptions that could cause actual results to differ materially from those expressed in any forward-looking statements. Accordingly, there are or will be important factors that could cause actual results to differ materially from those indicated in such statements and, therefore, you should not place undue reliance on any such statements and caution must be exercised in relying on forward-looking statements. Important risk factors that may cause such a difference include, but are not limited to: (i) the completion of the Transactions on anticipated terms and timing, including obtaining shareholder and regulatory approvals, anticipated tax treatment, unforeseen liabilities, future capital expenditures, revenues, expenses, earnings, synergies, economic performance, indebtedness, financial condition, losses, future prospects, business and management strategies, expansion and growth of Parent's and the Company's businesses and other conditions to the completion of the Transactions; (ii) failure to realize the anticipated benefits of the Transactions, including as a result of delay in completing the transaction or integrating the businesses of Parent and the Company; (iii) Parent's and the Company's ability to implement their business strategies; (iv) pricing trends; (v) potential litigation relating to the Transactions that could be instituted against Parent, the Company or their respective directors; (vi) the risk that disruptions from the Transactions will harm Parent's or the Company's business, including current plans and operations; (vii) the ability of Parent or the Company to retain and hire key personnel; (viii) potential adverse reactions or changes to business relationships resulting from the announcement, pendency or completion of the Transactions; (ix) uncertainty as to the long-term value of Parent's common stock; (x) legislative, regulatory and economic developments affecting Parent's and the Company's businesses; (xi) general economic and market developments and conditions; (xii) the evolving legal, regulatory and tax regimes under which Parent and the Company operate; (xiii) potential business uncertainty, including changes to existing business relationships, during the pendency of the Transactions that could affect Parent's or the Company's financial performance; (xiv) restrictions during the pendency of the Transactions that may impact Parent's or the Company's ability to pursue certain business opportunities or strategic transactions; (xv) unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as Parent's and the Company's response to any of the aforementioned factors; and (xvi) failure to receive the approval of the stockholders of Parent and the Company. These risks, as well as other risks associated with the Transactions, are more fully discussed in the Joint Proxy Statement/Prospectus to be filed with the SEC in connection with the Transactions. While the list of factors presented here is, and the list of factors presented in the Joint Proxy Statement/Prospectus will be, considered representative, no such list should be considered to be a complete statement of all potential risks and uncertainties. Unlisted factors may present significant additional obstacles to the realization of forward-looking statements. Consequences of material differences in results as compared with those anticipated in the forward-looking statements could include, among other things, business disruption, operational problems, financial loss, legal liability to third parties and similar risks, any of which could have a material adverse effect on Parent's or the Company's consolidated financial condition, results of operations or liquidity. Neither Parent nor the Company assumes any obligation to publicly provide revisions or updates to any forward-looking statements, whether as a result of new information, future developments or otherwise, should circumstances change, except as otherwise required by securities and other applicable laws.
