AI brief of an SEC Form 8-K · MasterBrand (MBC)

MasterBrand posts first-quarter net loss of $15.4 million on 6.4% sales decline

Negative Impact 4 of 5 earnings Written later

MasterBrand reported first-quarter 2026 net sales of $618.0 million, down 6.4% from a year earlier, and a net loss of $15.4 million, compared with net income of $13.3 million in the prior-year quarter. Adjusted EBITDA fell to $28.0 million from $67.1 million, and the company now expects its full-year 2026 effective tax rate to be elevated, citing non-deductible costs tied to its pending combination with American Woodmark.

Key points

  • Net sales were $618.0 million, down from $660.3 million, following a mid-single-digit market decline and slower housing completions.
  • Net loss was $(15.4) million versus net income of $13.3 million; diluted EPS was $(0.12) and adjusted diluted EPS was $0.06, compared with $0.18.
  • Second-quarter 2026 adjusted EBITDA is guided to $51 million to $61 million, with adjusted diluted EPS of $0.03 to $0.13.
  • The company is no longer reiterating its prior outlook for full-year effective tax rate improvement; the merger with American Woodmark is expected to close in the second calendar quarter of 2026.
