Apogee Therapeutics files Form 15-12G to terminate SEC registration

What happened

Apogee Therapeutics, Inc. (ticker APGE) submitted a Form 15‑12G to the U.S. Securities and Exchange Commission on September 14 2026.

The filing, titled “Certification and Notice of Termination of Registration,” indicates that the company is terminating its registration of its common stock under Section 12(g) of the Securities Exchange Act of 1934 and suspending its duty to file periodic reports under Sections 13 and 15(d).

The company reported that, as of the certification date, there was only one holder of record for its common stock.

Company background

Apogee Therapeutics, Inc. develops and commercializes biological products, primarily focused on therapeutic treatments. The company is headquartered in North Chicago, Illinois, and its common stock has a par value of $0.00001 per share.

What this means

A Form 15‑12G is used by a company to formally notify the SEC that it is ending its registration under Section 12(g). This typically occurs when a company no longer meets the requirements for a public reporting company, such as having fewer than 300 holders of record for its securities, or when it chooses to go private or otherwise cease public reporting.

By checking the boxes for Rule 12g‑4(a)(1) and Rule 12h‑3(b)(1)(i), Apogee indicated that it is relying on the provisions that allow termination of registration when the number of shareholders falls below the threshold and when the company has filed a final report with the SEC.

With registration terminated, Apogee is no longer required to file Forms 10‑K, 10‑Q, or 8‑K, and its common stock will be removed from any SEC‑regulated exchange listings. Holders of the stock will retain ownership, but the shares will trade, if at all, on a less regulated market or over the counter.

The filing does not provide a reason for the deregistration, so the specific motive—whether a strategic move to go private, a merger, or simply a decline in shareholder count—cannot be confirmed from the available information.
