STERICYCLE, INC.

Until 4 November 2024, Stericycle, Inc.’s common stock traded on the Nasdaq Global Select Market under the ticker symbol SRCL, and its shareholder base consisted of the institutional and retail investors typical of a Nasdaq-listed company, with major holders reported through Schedule 13D and 13G beneficial-ownership filings with the US Securities and Exchange Commission. Following completion of Waste Management, Inc.’s acquisition of Stericycle on 4 November 2024, Stericycle’s shares were delisted and withdrawn from Nasdaq trading; the company no longer has publicly traded stock, and Schedule 13D/13G filings are no longer applicable to it.

According to the Form 8-K that Stericycle filed with the SEC on 4 November 2024, the merger converted each outstanding share of common stock into 62.00 US dollars in cash and left Stericycle, Inc. as an indirect wholly-owned subsidiary of Waste Management, Inc. On this basis, Waste Management, Inc. is Stericycle’s sole shareholder as of the closing date, and no other person or entity holds a disclosed ownership interest in Stericycle, Inc.

This profile’s underlying registry data lists a shareholder table showing multiple institutional funds (including index and asset-management funds) each holding percentages of roughly one to five percent, refreshed as of September 2026. That table reflects Stericycle’s pre-acquisition public shareholder register, last accurate while its stock traded publicly, and does not describe Stericycle’s actual current ownership, which has been wholly held by Waste Management, Inc. since 4 November 2024. It should not be relied on as a current shareholder list.

Ultimate beneficial ownership. Because Stericycle, Inc. is wholly owned by Waste Management, Inc., itself a widely held, separately listed public company (NYSE: WM) without a single disclosed controlling shareholder, no individual ultimate beneficial owner can be identified for Stericycle, Inc. Ownership runs through a public company with dispersed institutional and public shareholders, so no natural person is disclosed as meeting a beneficial-ownership threshold.

Data availability. Shareholder information is full and current for the period after 4 November 2024 (100 percent ownership by Waste Management, Inc., per SEC Form 8-K), but historical, pre-delisting shareholder detail is available only through Stericycle’s last SEC filings made while it was independently listed.

As of 4 November 2024, Stericycle, Inc.’s board of directors and several executive officers were replaced in connection with the completion of Waste Management, Inc.’s acquisition of the company. According to the Form 8-K that Stericycle filed with the SEC on 4 November 2024, ten members of the pre-merger board of directors — Robert S. Murley, Cindy J. Miller, Victoria L. Dolan, Naren K. Gursahaney, James L. Welch, J. Joel Hackney Jr., Stephen C. Hooley, Brian P. Anderson, Lynn D. Bleil and Thomas F. Chen — ceased to serve as directors effective on completion of the merger, and Rafael E. Carrasco and Courtney A. Tippy became Stericycle’s new directors.

The same filing reports that Cindy J. Miller, Janet H. Zelenka, S. Cory White, Daniel V. Ginnetti, Kurt M. Rogers and Richard J. Hoffman ceased to be executive officers of Stericycle, and that Rafael E. Carrasco, Mark A. Lockett, Courtney A. Tippy, James A. Wilson, John Carroll, Leslie K. Nagy, Jeff Bennett and Jeff Viola became officers of the company; the filing does not specify each individual’s new job title. Nationality and country of residence are not disclosed in this filing for any of the named individuals.

Recent officer changes. Effective 4 November 2024: (1) ten directors, including Robert S. Murley and Stephen C. Hooley, ceased to serve on the board; (2) Rafael E. Carrasco and Courtney A. Tippy were appointed as new directors; (3) six named executive officers departed and eight new officers, including Carrasco and Tippy, were appointed. Source: Stericycle, Inc. Form 8-K filed with the SEC on 4 November 2024.

This profile’s underlying registry record lists a set of officers under the generic title “Governor,” several of whom — including Stephen C. Hooley, Robert S. Murley, Lynn Bleil and Brian P. Anderson — correspond to members of Stericycle’s pre-merger board described above, all of whom ceased to hold office effective 4 November 2024. That registry listing should therefore be treated as historical rather than current.

Data availability. Officer information for Stericycle is partial: the 4 November 2024 Form 8-K names the individuals who left and joined the board and executive officer group but does not disclose their specific titles, nationality or country of residence. Because Stericycle no longer files periodic reports with the SEC as an independent registrant, more recent changes to its officers may not be publicly available.

Until 4 November 2024, Stericycle, Inc. was an independent, Nasdaq-listed public company with no verified parent. Effective that date, Waste Management, Inc. (NYSE: WM) completed its previously announced acquisition of Stericycle: Stag Merger Sub Inc., a Delaware corporation and indirect wholly-owned subsidiary of Waste Management, Inc., merged with and into Stericycle, with Stericycle continuing as the surviving corporation. As a result, Stericycle, Inc. is now an indirect wholly-owned subsidiary of Waste Management, Inc., its ultimate parent, for consideration of 62.00 US dollars per share in a transaction valued at approximately 7.2 billion US dollars. The Form 8-K disclosing the merger does not name a specific intermediate holding company between Waste Management, Inc. and Stericycle beyond describing the relationship as “indirect,” so Stericycle’s immediate parent entity is not separately confirmed; ownership is reported as 100 percent.

Waste Management has stated that Stericycle’s regulated medical waste and secure information destruction operations are now managed as part of its WM Healthcare Solutions division alongside Waste Management’s existing waste-services business.

Before the acquisition, Stericycle, Inc. itself controlled numerous direct and indirect subsidiaries. Exhibit 21 to its Form 10-K for the year ended 31 December 2023 listed dozens of operating subsidiaries in the United States and abroad, including Stericycle International, LLC and Stericycle Management, LLC (both Delaware) and Stericycle of Washington, Inc. in the United States, and non-US entities such as Stericycle ULC (Canada), SRCL Limited and Shred-it Limited (United Kingdom), SRCL Consenur S.L.U. (Spain), and further subsidiaries in Portugal, Belgium, Puerto Rico and Barbados. This subsidiary list reflects the last publicly disclosed pre-acquisition group structure; whether each entity remains a subsidiary of Stericycle under Waste Management’s ownership has not been independently reconfirmed here.

Recent structural changes. (1) Stericycle entered into an Agreement and Plan of Merger with Waste Management, Inc. and Stag Merger Sub Inc. on 3 June 2024. (2) The merger completed on 4 November 2024, making Stericycle an indirect wholly-owned subsidiary of Waste Management, Inc. and delisting its shares from Nasdaq. (3) Stericycle’s certificate of incorporation and bylaws were amended and restated in connection with the merger’s completion.

Data availability. Corporate-linkage information is partial: the immediate, direct parent entity between Waste Management, Inc. and Stericycle is not disclosed in the reviewed filing, and Stericycle’s pre-acquisition subsidiary list has not been independently reconfirmed as current under its new ownership.
