What happened?
Shares of ceiling and wall solutions company Armstrong World Industries (NYSE: AWI) fell 5.7% in the morning session after the company reported third-quarter earnings that missed analyst expectations and issued full-year profit guidance below consensus estimates.
According to a company press release, Armstrong World reported third-quarter net sales of $475.8 million, up 11.9% year on year, and adjusted earnings of $2.26 per share. While net sales topped Wall Street expectations of $473 million, adjusted profit fell short of analyst estimates of $2.39 per share. The company updated its full-year guidance amid accelerating inflationary pressures, cost burdens, and timing-related mix headwinds in Mineral Fiber sales.
Management lowered its full-year adjusted earnings guidance to $8.35 per share at the midpoint and projected adjusted EBITDA of $607 million, falling short of analyst expectations of $613.2 million. Although the business achieved double-digit Architectural Specialties sales growth and a 12% rise in operating income, higher cost pressures and a trimmed earnings outlook dampened investor sentiment.
