The Company revised the financial information and disclosures included in the 2017 10-K as a result of the Company's previously announced segment reorganization and retrospective adoption of new accounting pronouncements.

~~The Registration~~Forward ~~Statement~~Looking has not been declared effective by the SEC. This communication shall neither constitute an offer to sell or the solicitation of an offer to buy any securities, which will only be made by Agiliti after the Registration Statement is effective. Statements

~~Forward~~Certain ~~Looking~~statements ~~Statements~~made herein include forward looking statements within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Specifically, the words “estimates,” “projected,” “expects,” “anticipates,” “forecasts,” “plans,” “intends,” “believes,” “seeks,” “may,” “will,” “should,” “future,” “propose” and variations of these words or similar expressions (or the negative versions of such words or expressions) are intended to identify forward-looking statements. These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside FSAC’s or UHS’s management’s control, that could cause actual results or outcomes to differ materially from those discussed in the forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described in the section entitled “Risk Factors” in the Prospectus filed by FSAC with the SEC and those described in the section entitled “Risk Factors” in UHS’s annual report on Form 10-K for the year ended December 31, 2017 filed with the SEC, as well as UHS’s other filings with the SEC. Important factors, among others, that may affect actual results or outcomes include: the inability to complete the transactions contemplated by the proposed Business Combination; the inability to recognize the anticipated benefits of the proposed Business Combination, which may be affected by, among other things, the amount of cash available following any redemptions by FSAC stockholders; the ability to meet NASDAQ’s listing standards following the consummation of the transactions contemplated by the proposed Business Combination; and costs related to the proposed Business Combination. Important factors that could cause the combined company’s actual results or outcomes to differ materially from those discussed in the forward-looking statements include: UHS’s history of net losses; the need for substantial cash to operate and expand the combined company’s business as planned; the combined company’s expected substantial outstanding debt following the business combination; a decrease in the number of patients the combined company’s customers serve; the combined company’s ability to effect change in the manner in which healthcare providers traditionally procure medical equipment; the absence of long-term commitments with customers; the combined company’s ability to renew contracts with group purchasing organizations and integrated delivery networks; changes in reimbursement rates and policies by third-party payors; the impact of healthcare reform initiatives; the impact of significant regulation of the healthcare industry and the need to comply with those regulations; the effect of prolonged negative changes in domestic and global economic conditions; difficulties or delays in the combined company’s continued expansion into certain of UHS’s businesses/geographic markets and developments of new businesses/geographic markets; additional credit risks in increasing business with home care providers and nursing homes, impacts of equipment product recalls or obsolescence; and increases in vendor costs that cannot be passed through to the combined company’s customers.

We believe statements in Exhibit 99.1 looking forward in time involve risks and uncertainties. The following factors, among others, could adversely affect our business, operations and financial condition, causing our actual results to differ materially from those expressed in any forward-looking statements:2

2Neither FSAC nor UHS undertakes any obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.

~~We undertake~~Item ~~no obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law~~9.01. InFinancial ~~light~~Statements ~~of these risks, uncertainties~~ and ~~assumptions, the forward-looking events included in Exhibit 99.1 might not occur~~ Exhibits
