Navitas Semiconductor Corp (NVTS) experienced a significant after-hours plunge of 5.03% on Monday, reversing gains from the regular trading session.

The sharp decline appears to be driven by two key factors. Firstly, the company's Q1 revenue is expected to decline year-over-year, which weighed on investor sentiment despite improvements in other financial metrics. Secondly, Navitas Semiconductor filed for a mixed shelf offering of up to $250 million, a move that could potentially dilute existing shareholders' equity.

These developments triggered a selloff in the post-market session as investors reacted to the combination of near-term revenue challenges and the potential dilution from the proposed capital raise.
