Applied Therapeutics ends S-3 after going private

Applied Therapeutics, Inc. has filed a post-effective amendment to shut down a prior Form S-3 resale registration.

Rhea-AI Filing Summary

Applied Therapeutics, Inc. has filed a post-effective amendment to shut down a prior Form S-3 resale registration. The original shelf allowed selling stockholders to offer up to 14,285,714 shares of common stock, but the company has since completed a merger.

On February 3, 2026, a subsidiary of Cycle Group Holdings Limited merged with Applied Therapeutics, leaving Applied Therapeutics as a private company and an indirect wholly owned subsidiary of Cycle Group Holdings. Because of this change, the company is terminating all offerings under the S-3 and deregistering any shares that remained unsold, so there are no securities left registered under that statement.

What does Applied Therapeutics (APLT) change in this post-effective amendment?

Applied Therapeutics is terminating its prior Form S-3 registration statement and deregistering any unsold securities. This means the earlier shelf for selling stockholders is no longer effective, and no securities remain registered under that specific S-3.

How many shares were originally covered by Applied Therapeutics’ S-3 shelf?

The original Form S-3 shelf covered the resale of up to 14,285,714 shares of Applied Therapeutics common stock. These shares were registered for offer and sale by specified selling stockholders, rather than as a primary capital-raising offering by the company itself.

Why is Applied Therapeutics (APLT) deregistering securities from its S-3?

Applied Therapeutics is deregistering the securities because it completed a merger with AT2B, Inc., a subsidiary of Cycle Group Holdings Limited. After the merger, Applied Therapeutics became a private, indirect wholly owned subsidiary, so it is ending all offerings under the S-3.

What is Applied Therapeutics’ corporate status after the merger mentioned in the amendment?

After the merger, Applied Therapeutics survives as a private company and an indirect wholly owned subsidiary of Cycle Group Holdings Limited. The merger combined Applied Therapeutics with AT2B, Inc., a Delaware corporation that was an indirect wholly owned subsidiary of Cycle Group Holdings.

Does Applied Therapeutics’ S-3 registration statement remain effective after this filing?

No. The post-effective amendment expressly terminates the effectiveness of the Form S-3 registration statement. It also removes from registration any securities that were previously registered under that filing but remained unsold as of the amendment’s effective date.

Where can investors find more details on the Applied Therapeutics merger agreement?

Further details on the merger and related agreement are available in the merger agreement filed as Exhibit 2.1 to Applied Therapeutics’ Current Report on Form 8-K, submitted to the SEC on December 12, 2025, which describes the transaction terms and related provisions.
