Will the Somnigroup / Leggett & Platt merger close by January 13, 2027?

Announced industrial M&A with negotiated outside date and bilateral termination fees closes at ~85-92% base rate. Discount for vertical integration antitrust complexity: Leggett supplies Serta Simmons and other SGI competitors, which invites DOJ 'foreclosure of inputs' scrutiny. Customer ring-fencing commitment in joint PR addresses most of this, but not all. SGI's Mattress Firm FTC remedy (43% third-party floor slots, monitored) demonstrates regulatory competence. All-stock structure eliminates financing risk. 9-month window is tight if DOJ opens a second request. Net: 0.75.

Decision tree: P(shareholder approval) * P(regulatory clearance) * P(no MAC/renegotiation). Shareholder approval ~0.90 (Leggett at distressed multiples, 0.1455 exchange is attractive to LEG holders). Regulatory ~0.85 (customer ring-fencing substantial mitigant; Mattress Firm case sets precedent). MAC ~0.97 (bedding industry already trough-priced, low incremental risk). Joint: 0.90 * 0.85 * 0.97 = 0.74. Round up slightly for SGI's demonstrated regulatory competence = 0.78.

Lower-end view: vertical integration deals involving component suppliers to direct competitors are the classic DOJ case study. Even with customer ring-fencing, a DOJ second request could consume 6-12 months, taking SGI past the outside date. Asymmetric termination fees ($64M SGI / $80M LEG) suggest SGI anticipated the possibility of walking. 9-month window is tight. Base 85% * 0.85 antitrust discount = 0.72.

Announced deals with binding agreement and outside date typically close 85-90% of the time. Vertical integration with customer ring-fencing commitment is moderate-risk antitrust setup — Customers protected, but DOJ still investigates horizontal effects on competitors' supply. SGI's Mattress Firm FTC remedy handling is strong reference. All-stock removes financing risk. Net: 0.76.

Risk-adjusted base case: 90% deal closure * 0.82 antitrust pass factor = 0.74. Antitrust factor reflects: (+) customer ring-fencing, all-stock, management track record; (-) vertical integration into supplier-to-competitors, 9-month window tight. Shareholder vote low risk (distressed LEG multiple attractive at 0.1455 ratio).

Conservative reading: vertical integration deals with customer/supplier overlap see ~70-75% closure rates historically. SGI's Mattress Firm precedent helps but Leggett is arguably more complex (multiple competitor customers vs single-retailer case). 9-month window leaves little margin for DOJ delays. Net: 0.72.

Announced M&A with outside date ~9 months closes in ~75-85% of cases absent major antitrust concerns. Customer ring-fencing addresses vertical integration concerns. Base rate minus antitrust discount = 0.75.

All-stock, negotiated outside date, bilateral termination fees = strong deal structure. Shareholder approval at distressed Leggett price should be straightforward. Antitrust risk moderate given ring-fencing. Settle at 0.78.

Cautious 0.73: Leggett's component-supplier relationships with SGI competitors create unique antitrust setup. SGI's Mattress Firm experience is positive precedent. 9-month window creates execution timing pressure. Net 0.73.
