DEREGISTRATION OF SECURITIES

These post-effective amendments (the “Post-Effective Amendments”), filed by Inari Medical, Inc., a Delaware corporation (the “Company”), remove from registration all shares of common stock, par value $0.001 per share, of the Company (the “Common Stock”) previously registered under the following Registration Statements on Form S-8 filed by the Company (the “Registration Statements”) with the U.S. Securities and Exchange Commission (the “SEC”) pertaining to the registration of shares of Common Stock.

On January 6, 2025, the Company entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Stryker Corporation, a Delaware corporation (“Parent”), and, by way of a joinder dated January 7, 2025, Eagle 1 Merger Sub, Inc., a Delaware corporation and a wholly owned subsidiary of Parent (“Offeror”). On February 19, 2025, pursuant to the Merger Agreement, Offeror merged with and into the Company, with the Company surviving as a wholly owned subsidiary of Parent (the “Merger”).

As a result of the Merger, the Company has terminated all offerings of the Company’s securities registered pursuant to its existing registration statements under the Securities Act of 1933, as amended, including the Registration Statements. The Company, by filing these Post-Effective Amendments, hereby terminates the effectiveness of the Registration Statements and removes from registration any and all plan interests and any and all securities registered for issuance under the Registration Statements that remain unsold as of the date hereof. This filing is made in accordance with an undertaking made by the Company in each of the Registration Statements to remove from registration by means of a post-effective amendment any securities that had been registered for issuance that remain unsold at the termination of the offering.
