As previously announced, on June 14, 2026, Roku, Inc., a Delaware corporation (the "Company" or "Roku"), entered into an Agreement and Plan of Merger (the "Merger Agreement") with Fox Corporation, a Delaware corporation ("FOX" or "Parent"), Falcon Merger Sub 1, Inc., a Delaware corporation and wholly owned subsidiary of FOX ("Merger Sub 1"), and Falcon Merger Sub 2, LLC, a Delaware limited liability company and wholly owned subsidiary of FOX ("Merger Sub 2"), pursuant to which, subject to the terms and conditions of the Merger Agreement, (i) Merger Sub 1 will merge with and into Roku (the "First Merger"), with Roku continuing as the surviving corporation (the "Surviving Corporation") and becoming a wholly owned subsidiary of FOX, and (ii) immediately following the First Merger, and as the second step in a single integrated transaction with the First Merger, the Surviving Corporation will merge with and into Merger Sub 2 (the "Second Merger" and, together with the First Merger, the "Mergers"), with Merger Sub 2 continuing as the surviving entity and a wholly owned subsidiary of FOX. Capitalized terms used but not defined herein have the meanings specified in the Merger Agreement.

In connection with the Mergers and the other transactions contemplated by the Merger Agreement (the "Transactions"), on August 7, 2026, Parent filed a registration statement on Form S-4 (as amended on August 21, 2026, the "Registration Statement") with the Securities and Exchange Commission (the "SEC"), which includes a prospectus with respect to the shares of Parent Class A Common Stock to be issued in the Mergers and a joint proxy statement for the Company's and Parent's respective stockholder meetings. On September 1, 2026, the Registration Statement was declared effective, Parent filed a final prospectus, and the Company filed a definitive proxy statement (together with the final prospectus, the "Joint Proxy Statement/Prospectus"). The Joint Proxy Statement/Prospectus was mailed to stockholders of the Company and Parent on or about September 1, 2026.

Litigation Related to the Mergers

Since the filing of the Joint Proxy Statement/Prospectus, Roku has received certain demand letters from purported stockholders of Roku generally alleging omissions or misstatements in the disclosures in the Joint Proxy Statement/Prospectus and requesting that Roku file corrective disclosures prior to the Roku Special Meeting (collectively, the "Demand Letters").

Although Roku believes that the disclosures in the Joint Proxy Statement/Prospectus comply with all applicable laws and that the Demand Letters are without merit, in order to avoid nuisance and possible expense and business delays and provide additional information to its stockholders, Roku has determined voluntarily to supplement certain disclosures in the Joint Proxy Statement/Prospectus with the supplemental disclosures set forth below (the "Supplemental Disclosures"). Nothing in the Supplemental Disclosures should be deemed an admission of the legal merit, necessity or materiality under applicable laws of any of the claims or allegations in the Demand Letters or the disclosures set forth herein. To the contrary, Roku specifically denies all allegations in the Demand Letters, including that any additional disclosure was or is required or material.

It is possible that lawsuits may be filed challenging the Transactions against Roku or naming the members of the Roku board of directors or others as defendants or that additional demand letters will be received by Roku. If this occurs, Roku will not necessarily publicly disclose the filing or receipt of any such lawsuit or demand letter unless required by law.

Supplement to the Joint Proxy Statement/Prospectus

The supplemental information should be read in conjunction with the Joint Proxy Statement/Prospectus, which should be read in its entirety. Page references in the below disclosures are to pages in the Joint Proxy Statement/Prospectus, and defined terms used below but not defined herein have the meanings set forth in the Joint Proxy Statement/Prospectus. To the extent the information in the Supplemental Disclosures differs from or conflicts with the information contained in the Joint Proxy Statement/Prospectus, the information set forth below shall be deemed to supersede or supplement the respective information in the Joint Proxy Statement/Prospectus. Nothing in this Current Report on Form 8-K shall be deemed an admission of the legal necessity or materiality under applicable laws of any of the disclosures set forth herein. Except as otherwise described in the below Supplemental Disclosures or the documents referred to, contained in or incorporated by reference herein, the Joint Proxy Statement/Prospectus, the annexes to the Joint Proxy Statement/Prospectus and the documents referred to, contained in or incorporated by reference in the Joint Proxy Statement/Prospectus are not otherwise modified, supplemented or amended. For clarity, new text within restated paragraphs from the Joint Proxy Statement/Prospectus is highlighted with bold, underlined text, while deleted text is bold and stricken-through.

Cautionary Statement Regarding Forward-Looking Statements

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 Transactions 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 stockholder 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) litigation relating to the Transactions that has been or 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, as well as in the following periodic reports filed with the SEC: (a) the Annual Report on Form 10-K of Fox Corporation for the fiscal year ended June 30, 2026, filed with the SEC on August 6, 2026; and (b) the Quarterly Report on Form 10-Q of Roku, Inc. for the quarter ended June 30, 2026, filed with the SEC on August 6, 2026. While the lists of factors presented here, in the Joint Proxy Statement/Prospectus, and in the foregoing periodic reports are 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.
