01—Abstract

Summary

Summary of the 8-K filed October 6, 2025. Cited figures are marked; the original filing is the authoritative source.

TransDigm Group (NYSE: TDG) announced on October 6, 2025 that it completed its acquisition of the Simmonds Precision Products, Inc. business from Goodrich Corporation, a subsidiary of RTX Corporation, for approximately $765 milliona in cash, including certain tax benefits.

The deal was funded entirely from cash on hand, and the agreement was first disclosed in an 8-K filed June 30, 2025. The filing itself is brief, furnishing the press release as Exhibit 99.1 under Item 8.01 (Other Events), so the key financial details come from that release rather than from detailed financial statements. Simmonds is a designer and manufacturer of fuel and proximity sensing and structural health monitoring solutions for aerospace and defense.

Per the press release, it is expected to generate roughly $350 millionb in revenue for calendar 2025, about 40% of which comes from aftermarket sales, and nearly all revenue derives from proprietary products. The business employs approximately 900 people and is headquartered in Vergennes, Vermont. Proprietary, aftermarket-heavy product lines are the kind of profile TransDigm typically targets, since they support high margins and recurring revenue tied to installed aircraft fleets.

For investors, the transaction is a bolt-on acquisition that adds sensing and monitoring capabilities to TransDigm's portfolio at a cost of about 2.2xc expected 2025 revenue, without new debt financing. The filing does not disclose purchase price multiples on EBITDA, expected margins, or synergy targets, so those factors would need to come from TransDigm's earnings materials. Forward-looking risks flagged in the release include integration execution, indebtedness, defense budget exposure, and aerospace demand sensitivity.
