ATIP Tender Offer Employee Letter

From: Sharon Vitti
To: All Employees
Subject: Strengthening ATI’s Financial Foundation

Team,

As we continue executing our strategic plan and positioning ATI for long-term growth, a key objective is to strengthen our financial foundation and simplify our capital structure. In connection with those efforts, earlier today we announced that ATI is offering to repurchase up to 1.65 million shares of the Company’s publicly traded common stock. This action is intended to provide liquidity to our stockholders and to help us on a path to greater financial flexibility in the future.

This stock repurchase will be conducted through a tender offer process — which is described in the press release. To keep it simple, a tender offer is a proposal made directly to a company’s stockholders to purchase their stock. In this instance, ATI is offering to buy our stockholders’ common shares for $2.85 per share in cash. To facilitate the tender, some of our investors have agreed to provide financing, as described in the press release.

For those of you who hold ATI common stock, please note that our Board of Directors recommends that stockholders tender their shares ahead of the January 15, 2025 deadline. You can reach out to our information agent, Innisfree M&A Incorporated, by telephone at (888) 750-5835, or by writing to 501 Madison Avenue, 20th Floor, New York, New York, 10022, with any questions or requests for additional information about the tender offer.

Most importantly, it remains business as usual across ATI. We continue to take care of our patients, focus on operational excellence and invest in our teams, building on our momentum in 2024 to start the new year. The best way to contribute to these efforts is to stay focused on your daily responsibilities in support of the patients we serve and our national practice.

Please reach out to your manager should you have any questions.

Thank you for your hard work and dedication to ATI as we advance our purpose of making every life an active life.

Kind regards,

Sharon
