Forward-Looking Statements

This communication contains “forward-looking statements” within the meaning of The Private Securities Litigation Reform Act of 1995. Forward-looking statements include, without limitation, statements regarding the estimated future financial performance, financial position and financial impacts of the potential transaction, the satisfaction of closing conditions to the potential transaction and the private placement, the level of redemptions by GSAH’s public stockholders and purchase price adjustments in connection with the potential transaction, the timing of the completion of the potential transaction, the anticipated pro forma enterprise value and Adjusted EBITDA of the combined company following the potential transaction, anticipated ownership percentages of the combined company’s stockholders following the potential transaction, and the business strategy, plans and objectives of management for future operations, including as they relate to the potential transaction. Such statements can be identified by the fact that they do not relate strictly to historical or current facts. When used in this communication, words such as “pro forma,” “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “should,” “strive,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. When GSAH or Mirion discusses its strategies or plans, including as they relate to the potential transaction, it is making projections, forecasts and forward-looking statements. Such statements are based on the beliefs of, as well as assumptions made by and information currently available to, GSAH’s or Mirion’s management.

These forward-looking statements involve significant risk and uncertainties that could cause the actual results to differ materially from the expected results. Most of these factors are outside GSAH’s and Mirion’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: (1) GSAH’s ability to complete the potential transaction or, if GSAH does not complete the potential transaction, any other initial business combination; (2) satisfaction or waiver (if applicable) of the conditions to the potential transaction, including with respect to the approval of the stockholders of GSAH; (3) the ability to maintain the listing of the combined company’s securities on the New York Stock Exchange; (4) the inability to complete the private placement; (5) the risk that the proposed transaction disrupts current plans and operations of GSAH or Mirion as a result of the announcement and consummation of the transaction described herein; (6) the ability to recognize the anticipated benefits of the proposed transaction, which may be affected by, among other things, competition, the ability of the combined company to grow and manage growth profitably, maintain relationships with customers and suppliers and retain its management and key employees; (7) costs related to the proposed transaction; (8) changes in applicable laws or regulations and delays in obtaining, adverse conditions contained in, or the inability to obtain necessary regulatory approvals required to complete the potential transaction; (9) the possibility that GSAH and Mirion may be adversely affected by other economic, business, and/or competitive factors; (10) the outcome of any legal proceedings that may be instituted against GSAH, Mirion or any of their respective directors or officers, following the announcement of the potential transaction; (11) the failure to realize anticipated pro forma results or projections and underlying assumptions, including with respect to estimated stockholder redemptions, purchase price and other adjustments; (12) future global, regional or local political, market and social conditions, including due to the COVID-19 pandemic; and (13) other risks and uncertainties indicated from time to time in the preliminary proxy statement of GSAH, including those under “Risk Factors” therein, and other documents filed or to be filed with the Securities and Exchange Commission (“SEC”) by GSAH.

Neither GSAH nor Mirion undertakes any obligation to update its forward-looking statements to reflect events or circumstances after the date of this release. Additional risks and uncertainties are identified and discussed in GSAH’s reports filed with the SEC and available at the SEC’s website at http://www.sec.gov.
