No Offer or Solicitation

This communication relates to a proposed business combination transaction (the “Merger”) between Sitio Rotyalties Corp. (“Sitio”) and Brigham Minerals, Inc. (“Brigham”). This communication is for informational purposes only and does not constitute an offer to sell or the solicitation of an offer to buy any securities or a solicitation of any vote or approval, in any jurisdiction, pursuant to the Merger or otherwise, nor shall there be any sale, issuance, exchange or transfer of the securities referred to in this document in any jurisdiction in contravention of applicable law. 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.

Forward-Looking Statements

The information included herein and in any oral statements made in connection herewith include “forward-looking statements” within the meaning of Section 27A of the Securities Act, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of present or historical fact included herein, regarding the proposed Merger between Sitio and Brigham, the likelihood that the conditions to the consummation of the Merger will be satisfied on a timely basis or at all, Sitio’s and Brigham’s ability to consummate the Merger at any time or at all, the benefits of the Merger and the post-combination company’s future financial performance following the Merger, as well as the post-combination company’s strategy, future operations, financial position, estimated revenues, and losses, projected costs, prospects, plans and objectives of management are forward looking statements. When used herein, including any oral statements made in connection herewith, the words “may,” “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project” and similar expressions and the negative of such words and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on Sitio’s and Brigham’s management’s current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. Such statements may be influenced by factors that could cause actual outcomes and results to differ materially from those projected. Except as otherwise required by applicable law, Sitio and Brigham disclaim any duty to update any forward-looking statements, all of which are expressly qualified by the statements in this section, to reflect events or circumstances after the date hereof. Sitio and Brigham caution you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of Sitio and Brigham. These risks include, but are not limited to, the post-combination company’s ability to successfully integrate Sitio’s and Brigham’s businesses and technologies; the risk that the expected benefits and synergies of the Merger may not be fully achieved in a timely manner, or at all; the risk that Sitio or Brigham will not, or that following the Merger, New Sitio will not, be able to retain and hire key personnel; the risk associated with Sitio’s and Brigham’s ability to obtain the approvals of their respective stockholders required to consummate the Mergers and the timing of the closing of the Merger, including the risk that the conditions to the transaction are not satisfied on a timely basis or at all or the failure of the transaction to close for any other reason or to close on the anticipated terms, including the anticipated tax treatment; the risk that any regulatory approval, consent or authorization that may be required for the Merger is not obtained or is obtained subject to conditions that are not anticipated; unanticipated difficulties or expenditures relating to the transaction, the response of business partners and retention as a result of the announcement and pendency of the transaction; Sitio’s ability to finance New Sitio (including the repayment of certain of Brigham’s indebtedness) on acceptable terms or at all; uncertainty as to the long-term value of New Sitio’s common stock; and the diversion of Sitio’s and Brigham’s management’s time on transaction-related matters. Should one or more of the risks or uncertainties described herein and in any oral statements made in connection therewith occur, or should underlying assumptions prove incorrect, actual results and plans could different materially from those expressed in any forward-looking statements. Additional information concerning these and other factors that may impact Sitio’s and Brigham’s expectations and projections can be found in Sitio’s periodic filings with the SEC, including Sitio’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021, Part II, Item 1A “Risk Factors” in Sitio’s Quarterly Reports on Form 10-Q and Current Reports on Form 8-K and Brigham’s periodic filings with the SEC, including Brigham’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and any subsequent Quarterly Reports on Form 10-Q and Current Reports on Form 8-K.
