Karman Holdings (NYSE: KRMN) experienced a significant overnight decline of 10.55%, reversing gains made during the regular trading session. The sharp drop occurred in after-hours trading following the release of the company's first-quarter financial results.

The plunge was primarily triggered by the company's adjusted earnings per share of $0.11 for the quarter, which missed the analyst consensus estimate of $0.12 by 8.33%. This earnings disappointment came despite the company reporting quarterly sales of $151.210 million, which slightly exceeded the $150.148 million estimate and represented a 51.02% increase from the same period last year.

Earlier in the day, the stock had rallied during regular trading on news that Karman Space & Defense secured conditional demand commitments for key space and defense programs with a potential total multi-year value exceeding $1 billion. However, this positive sentiment was overshadowed by the earnings miss in the after-hours session, leading to a full reversal of the intraday gains.
