These are expected to be treated as financial adjustments under the credit facility.
Analysis · SGI · Manufacturing
The all-stock acquisition of Leggett & Platt is now complete, creating a combined company with over 170 manufacturing facilities across 37 countries and more than 36,000 employees. Valued at approximately $2.3 billion based on Somnigroup's August 25 closing price, the deal leaves former Leggett & Platt shareholders owning roughly 9% of the combined company on a fully diluted basis. Management raised its annual run-rate synergy target to $75 million from the initial $50 million estimate — a 50% increase that signals greater confidence in integration benefits. The transaction reduced net leverage by approximately 0.2x, and the company expects to reach the midpoint of its 2.0-3.0x adjusted EBITDA target range by year-end. Somnigroup also disclosed approximately $60 million in combined annualized non-cash expenses from purchase accounting fair value adjustments, which will impact cost of goods sold and interest expense but are expected to be treated as financial adjustments under its credit facility. Tyson Hagale was named President of Leggett & Platt, effective immediately, reporting to CEO Karl Glassman. A business update call is scheduled for September 2, 2026.
