Item 7.01.  Regulation FD Disclosure.
On July 1, 2021, Magnite, Inc., a Delaware corporation (the "
Company
"), issued a press release announcing that it has consummated the acquisition (the "
Acquisition
") of ServeMotion, Inc., a Delaware corporation ("
SpringServe
"), through its wholly-owned subsidiary SpotX, Inc., a Delaware corporation ("
SpotX
"), pursuant to a definitive agreement entered into on July 1, 2021.  As a result of the Acquisition, SpringServe has become a wholly-owned subsidiary of SpotX, and a wholly-owned indirect subsidiary of the Company.  The full text of the press release issued in connection with the announcement of the Acquisition is furnished as Exhibit 99.1 to this Current Report on Form 8-K.
The information in this Item 7.01 (including Exhibit 99.1) shall not be deemed "filed" for purposes of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act or the Exchange Act, except as expressly set forth by specific reference in such a filing.
Forward Looking Statements
This Current Report on Form 8-K may include forward-looking statements, including statements based upon or relating to our expectations, assumptions, estimates, and projections.  In some cases, you can identify forward-looking statements by terms such as "may," "might," "will," "objective," "intend," "should," "could," "can," "would," "expect," "believe," "design," "anticipate," "estimate," "predict," "potential," "plan" or the negative of these terms, and similar expressions.  These statements are not guarantees of future performance; they reflect our current views with respect to future events and are based on assumptions and estimates and subject to known and unknown risks, uncertainties and other factors that may cause our actual results, performance or achievements to be materially different from expectations or results projected or implied by forward-looking statements.
We discuss many of the risks and additional factors that could cause actual results to differ materially from those anticipated by our forward-looking statements under the headings "Risk Factors" and "Management's Discussion and Analysis of Financial Condition and Results of Operations," and elsewhere in filings we have made and will make from time to time with the Securities and Exchange Commission, or SEC, including our Annual Report on Form 10-K for the year ended December 31, 2020 and subsequent Quarterly Reports on Form 10-Q for 2021. These forward-looking statements represent our estimates and assumptions only as of the date of the report in which they are included.  Unless required by federal securities laws, we assume no obligation to update any of these forward-looking statements, or to update the reasons actual results could differ materially from those anticipated, to reflect circumstances or events that occur after the statements are made.  Without limiting the foregoing, any guidance we may provide will generally be given only in connection with quarterly and annual earnings announcements, without interim updates, and we may appear at industry conferences or make other public statements without disclosing material nonpublic information in our possession.  Given these uncertainties, investors should not place undue reliance on these forward-looking statements.  Investors should read this Current Report on Form 8‑K and the documents that we reference in this Current Report on Form 8‑K and have filed or will file with the SEC completely and with the understanding that our actual future results may be materially different from what we expect.  We qualify all of our forward-looking statements by these cautionary statements.
