Limbach Holdings Inc. (LMB) experienced a sharp after-hours plunge of 6.92% following the release of its fourth-quarter financial results. The building systems solutions firm reported mixed performance, with earnings surpassing expectations but revenue falling short of analyst estimates.

The company reported Q4 adjusted earnings per share of $1.40, beating the FactSet consensus estimate of $1.24. However, revenue for the quarter came in at $186.9 million, missing the analyst expectation of $197.6 million. This revenue miss appears to be the primary driver behind the stock's negative after-hours reaction, overshadowing the positive earnings performance.

Despite the quarterly revenue shortfall, Limbach provided full-year 2026 revenue guidance in the range of $730 million to $760 million, which aligns with analyst expectations of approximately $746.1 million. The company also announced a $50 million share repurchase program and the relocation of its corporate headquarters to Tampa, Florida, as part of its 125th-anniversary initiatives.
