Somnigroup sold less in the three months ended June 30, and made more money doing it.

Revenue fell 3.0% to $1.8 billion versus the comparable three months a year earlier. Operating income rose 12.1% to $201.7 million, while net income climbed 12.0% to $110.9 million. At the latest close, Somnigroup shares were down 6.8% at $64.92.

The important wrinkle is that the sales comparison is being rewritten by Mattress Firm. Somnigroup owned the retailer for a full quarter this time, but sales between the wholesale business and Mattress Firm no longer count as consolidated revenue. One business got bigger in the reported numbers; another got smaller because an internal transaction disappeared. Corporate accounting, undefeated at making a simple sales line needlessly interesting.

Somnigroup described the change this way:

"The change in net sales was driven by the following: Mattress Firm net sales increased $265.6 million, or 17.2%, primarily driven by the inclusion of net sales for a full quarter in the first quarter of 2026 as compared to the first quarter of 2025, which included Mattress Firm for the stub period."

Somnigroup, 10-Q filed Aug. 7, 2026.

That increase was offset in part by the wholesale channel, where sales fell $140.6 million because sales to Mattress Firm were eliminated for a full period rather than a stub period. The consolidated top line therefore says less about unit demand than it usually would. The company has not supplied a clean, apples-to-apples organic sales figure in these receipts.

The profit line is cleaner, at least on its face. Gross margin expanded from 44.0% to 44.8%, and operating margin widened from 9.6% to 11.1%. Somnigroup attributed the gross-margin improvement to Mattress Firm synergies, the elimination of intercompany sales, operational efficiencies, and favorable mix.

"The improvement in gross margin was primarily driven by the achievement of synergies from the Mattress Firm Acquisition of 480 basis points, elimination of intercompany sales to Mattress Firm of 290 basis points, operational efficiencies of 190 basis points and favorable mix."

Somnigroup, 10-Q filed Aug. 7, 2026.

The quoted contributors add up to more than the reported margin expansion because other items pulled in the opposite direction. Somnigroup separately said commodity-cost inflation before pricing actions reduced gross margin by 100 basis points, partly offset by operational efficiencies. The business is showing integration benefits, but it is also carrying a live exposure to input costs and pricing timing.

Lower financing costs helped the bottom line too. Management said the company made net repayments of $272.1 million on its credit facilities, compared with net borrowings of $1.1 billion a year earlier, when it funded the Mattress Firm acquisition. It also said lower interest rates on variable-rate debt reduced interest expense.

Cash-flow signals moved in the same direction as earnings, though not without a footnote. Free-cash-flow margin improved by 3.5 percentage points, inventory fell 8.4%, and accounts receivable was essentially unchanged. Capital spending, meanwhile, rose 89.8%. The filing gives the figures, not a single explanation tying those working-capital and investment movements together.

Somnigroup's latest annual results show why this comparison matters: revenue reached $7.5 billion in 2025 after the acquisition, but operating margin was 10.1%, below the 12.9% recorded in 2024. The current three-month report supplies evidence that the integration can add margin, while its distorted sales bridge leaves the underlying growth rate harder to read.

Somnigroup's next quarterly report will provide another comparable three-month sales and margin bridge. The filing leaves open whether Mattress Firm's full-quarter comparison can support comparable revenue growth without giving back the margin gains.

The 10-Q leaves one question open: can Mattress Firm's full-quarter comparison support sales growth without giving back the margin gains?
