DEREGISTRATION OF SECURITIES

This Post-Effective Amendment No. 1 (this “Post-Effective Amendment”) to the Registration Statement on Form S-3 (File No. 333-255771) (the “Registration Statement”) filed with the Securities and Exchange Commission on May 5, 2021 is being filed to deregister all securities that were registered for issuance on the Registration Statement and remain unsold thereunder.

On March 7, 2022, the company formerly known as Welltower Inc., a Delaware corporation (“Old Welltower”), announced that it intended to implement a corporate reorganization into a new holding company structure commonly referred to as an Umbrella Partnership Real Estate Investment Trust, or UPREIT. On April 1, 2022, in connection with such intended reorganization, Old Welltower entered into an Agreement and Plan of Merger (the “Merger Agreement”) with WELL Merger Holdco Inc., a Delaware corporation, which was a wholly owned subsidiary of Old Welltower (“New Welltower”), and WELL Merger Holdco Sub Inc., a Delaware corporation, which was a wholly owned subsidiary of New Welltower (“Merger Sub”). Effective on April 1, 2022, pursuant to the terms of the Merger Agreement, Merger Sub merged with and into Old Welltower, with Old Welltower continuing as the surviving corporation and a wholly owned subsidiary of New Welltower (the “Merger”). The Merger was conducted pursuant to Section 251(g) of the General Corporation Law of the State of Delaware, which provides for the formation of a holding company (i.e., New Welltower) without a vote of the shareholders of the constituent corporation (i.e., Old Welltower).

At the effective time of the Merger, (a) the separate existence of Merger Sub ceased; and (b) each share of Old Welltower common stock issued and outstanding immediately prior to the Merger converted on a share-for-share basis into an issued and outstanding share of New Welltower common stock. In connection with the Merger, Old Welltower’s name was changed to Welltower OP Inc., and New Welltower inherited the name “Welltower Inc.” and became the successor issuer to Old Welltower pursuant to Rule 12g-3 under the Securities Exchange Act of 1934.

As a result of the Merger, Old Welltower terminated all offers and sales of its securities registered for issuance on the Registration Statement that remained unsold thereunder as of the date hereof.
