Corporate transaction and change in listing status

Triumph’s status as a public company changed following a merger transaction with affiliates of Warburg Pincus LLC and Berkshire Partners LLC. According to a Form 8-K filed on July 24, 2025, and related press releases, Triumph entered into an Agreement and Plan of Merger under which Titan BW Acquisition Merger Sub Inc., a wholly owned subsidiary of Titan BW Acquisition Holdco Inc., merged with and into Triumph Group, Inc., with Triumph surviving as a wholly owned subsidiary of the parent entity. Parent and Merger Sub are described as affiliates of investment funds managed by Warburg Pincus and Berkshire Partners.

At the effective time of the merger, each share of Triumph common stock issued and outstanding immediately prior to the effective time (subject to specified exceptions) was converted into the right to receive a cash merger consideration amount per share. As a result, all such shares ceased to be outstanding and were automatically cancelled. The Form 8-K explains that, following the merger, a change of control occurred and Triumph became a wholly owned subsidiary of the parent entity. The filing also notes that Triumph’s equity incentive plans and employee stock purchase plan were terminated as of the effective time.

In connection with the merger, Triumph notified the New York Stock Exchange that a certificate of merger had been filed and requested that the NYSE file a Form 25 to remove its common stock from listing and registration under Section 12(b) of the Exchange Act. A Form 25 filed by the NYSE on July 25, 2025, identifies Triumph Group Inc. and its common stock and indicates removal from listing and/or registration on the NYSE. A separate Form 25 filing references purchase rights. The Form 8-K states that trading of Triumph common stock on the NYSE, under the ticker symbol TGI, would be suspended prior to the opening of trading on July 25, 2025.

Subsequently, Triumph filed a Form 15 (Form 15-12G) dated August 4, 2025, certifying termination of registration of its common stock under Section 12(g) of the Exchange Act and suspension of its duty to file reports under Sections 13 and 15(d). The Form 15 notes that, on July 24, 2025, Merger Sub merged with and into Triumph, with Triumph surviving as a wholly owned subsidiary of Titan BW Acquisition Holdco Inc., and that the parent and merger subsidiary are affiliates of investment funds managed by Warburg Pincus and Berkshire Partners.

Implications for the TGI stock symbol

As a result of the merger and subsequent delisting and deregistration, TGI no longer trades on the New York Stock Exchange, and Triumph Group, Inc. is no longer an SEC-reporting public company. Historical references to TGI as a stock symbol relate to Triumph’s period as a listed issuer. The company continues to operate as a privately held aerospace and defense business under the ownership of affiliates of Warburg Pincus and Berkshire Partners, as described in the acquisition-related press releases.
