What Happened?

Shares of ceiling and wall solutions company Armstrong World Industries (NYSE:AWI) jumped 6.6% in the afternoon session after the company reported impressive fourth quarter 2024 results that blew past analysts' revenue and EPS expectations. Profitability improved as operating income climbed 24%, and adjusted EBITDA increased 14%, driven by volume gains and pricing power. These factors contributed to a significant EPS beat, with adjusted diluted earnings per share rising 23%. 

Looking ahead, AWI issued bullish full-year 2025 guidance, forecasting 9% to 11% revenue growth and an 8% to 12% increase in adjusted EBITDA, both above Wall Street's expectations. The company expects continued strength in its Architectural Specialties business following the recent acquisitions of Zahner, 3form, and BOK. Zooming out, we think this quarter featured some important positives.
