Resideo Technologies Inc. (REZI) experienced a significant after-hours plunge of 7.63% following the release of its first-quarter 2026 financial results.

The company reported GAAP earnings per share of $0.17 for Q1 2026, which fell substantially short of the analyst forecast of $0.60. While the company's adjusted EPS of $0.65 slightly exceeded the forecast of $0.61, the significant miss on the GAAP measure appears to have driven negative investor sentiment. The company reported Q1 revenue of $1,910 million and a gross margin of 28.8%.

Despite the quarterly earnings disappointment, Resideo reaffirmed its full-year 2026 revenue outlook in the range of $7.80 billion to $7.90 billion, compared with the FactSet estimate of $7.77 billion. The company also provided Q2 2026 guidance for net revenue between $1,916 million and $1,940 million and non-GAAP adjusted EPS in the range of $0.71 to $0.75.
