Somnigroup Completes $2.3 Billion Leggett & Platt Acquisition

Mixed Impact 4 of 5 m&a Written later

Somnigroup completed its all-stock acquisition of Leggett & Platt on August 26, 2026, a transaction the company values at about $2.3 billion including Leggett & Platt's existing debt. Former Leggett & Platt shareholders now own about 9% of the combined company on a fully diluted basis, which dilutes existing Somnigroup holders, while the company reports leverage reduced by about 0.2 times and a higher synergy target.

Key points

  • Merger closed August 26, 2026 under an agreement dated April 13, 2026; Leggett & Platt is now a wholly owned subsidiary.
  • Each Leggett & Platt share converted into 0.1455 Somnigroup shares; former Leggett & Platt shareholders own about 9% of the combined company.
  • Annual run-rate synergy target raised to $75 million from the initial $50 million; net leverage reduced by about 0.2 times.
  • The company expects about $50 million of annualized non-cash expense from fair value adjustments to the acquired business and about $10 million from the acquired bonds; $1.5 billion of Leggett & Platt notes remain outstanding.
