Enovix Corporation's stock experienced a significant after-hours plunge of 5.03% following the release of its fourth-quarter and full-year 2025 financial results.

While the company reported a Q4 revenue beat and a narrower-than-expected adjusted loss per share, investor sentiment turned negative due to disappointing forward guidance. The company's Q1 2026 revenue forecast of $6.5 million to $7.5 million fell short of analyst estimates of $8.34 million, raising concerns about near-term growth.

Further pressure came from details in the full-year report, which showed a 218% surge in interest expense to $21.6 million for FY 2025, contributing to a substantial net loss of $156.6 million. The company also reported a year-over-year decline in Q4 revenue, adding to the bearish outlook that drove the sell-off in the extended trading session.
