SUBJECT: Important News About Stericycle

Dear [NAME],

I’m reaching out to share that Stericycle has announced that it has entered into an agreement to be acquired by WM, one of North America’s leading providers of comprehensive environmental solutions. The WM leadership team identified Stericycle as an ideal partner as they sought to expand and diversify, and engaged our Board in discussions about a future together. While we did not seek to be acquired, we are confident that this transaction is the right next chapter for Stericycle.

We expect this transaction to enhance Stericycle’s value proposition with stronger, more diversified services and solutions and enable our business to help customers manage a greater volume and variety of materials safely, responsibly, and sustainably. Meanwhile, we’ll benefit as part of a larger, best-in-class organization. WM has greater resources to bolster capacity, drive innovation, and improve the customer experience. And there is more opportunity for our team members that comes along with that.

As we met with WM leaders to discuss the potential future together, it was evident that they deeply value our talented team. Our team members possess great expertise in managing regulated medical waste and secure information destruction services, and WM believes that our team’s knowledge and skills will be valuable as they expand their environmental services and solutions.

Until we complete this transaction – which is still subject to certain conditions and approvals – Stericycle and WM will continue to operate separately, just as we always have. It is business as usual until the transaction is complete. That means nothing about our current collective bargaining agreement changes. Nor will anything about your members’ benefits or compensation immediately change. We can assure you that WM has been advised of the bargaining obligation that exists with the unions and works councils that currently represent Stericycle employees through existing collective bargaining agreements.

After the closing date, both Stericycle and WM will work together to plan for a transition of Stericycle team members to WM’s benefits plans. Information around timing will be communicated in advance of the transition so your members may plan appropriately.

As we have information to share, we are committed to communicating clearly and transparently, and we will keep you all updated as appropriate. Please don’t hesitate to reach out with any questions.

Thank you.

Sincerely,

Cal Schmidt

Vice President, Global Labor

Such statements generally include words such as “believes,” “expects,” “intends,” “anticipates,” “estimates,” “continues,” “may,” “plan,” “will,” “goal,” or similar expressions. Forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and projections of our management about future events and are therefore subject to risks and uncertainties, many of which are outside Stericycle’s control, which could cause actual results to differ materially from what is contained in such forward-looking statements as a result of various factors, including, without limitation: (1) the inability to consummate the proposed transaction within the anticipated time period, or at all, due to any reason, including the failure to obtain stockholder approval to adopt the Agreement and Plan of Merger, dated as of June 3, 2024 (the “Merger Agreement”), the failure to obtain required regulatory approvals for the proposed transaction or the failure to satisfy the other conditions to the consummation of the proposed transaction; (2) the risk that the Merger Agreement may be terminated in circumstances requiring Stericycle to pay a termination fee; (3) the risk that the proposed transaction disrupts Stericycle’s current plans and operations or diverts management’s attention from its ongoing business; (4) the effect of the announcement of the proposed transaction on the ability of Stericycle to retain and hire key personnel and maintain relationships with its customers, suppliers and others with whom it does business; (5) the effect of the announcement of the proposed transaction on Stericycle’s operating results and business generally; (6) the significant costs, fees and expenses related to the proposed transaction; (7) the risk that Stericycle’s stock price may decline significantly if the proposed transaction is not consummated; (8) the nature, cost and outcome of any litigation and other legal proceedings, including any such proceedings related to the proposed transaction and instituted against Stericycle and/or its directors, executive officers or other related persons; and (9) other factors that could affect Stericycle’s business such as, without limitation, inflationary cost pressure in labor, supply chain, energy, and other expenses, decreases in the volume of regulated wastes or personal and confidential information collected from customers, and disruptions resulting from deployment of systems, disruptions in our supply chain, changing market conditions in the healthcare industry, competition and demand for services in the regulated waste and secure information destruction industries, Sorted Office Paper (“SOP”) pricing volatility or pricing volatility in other commodities, changes in the volume of paper processed by our secure information destruction business and the revenue generated from the sale of SOP, and changes in governmental regulation of the collection, transportation, treatment and disposal of regulated waste or the proper handling and protection of personal and confidential information.
