PBF Energy Inc (PBF) shares plummeted 5.00% during Thursday's intraday trading session, marking a sharp decline despite the company reporting a surprise profit for the fourth quarter.

The steep drop appears driven by investor concern over the company's full-year financial results. While PBF Energy swung to an adjusted net income in Q4, beating analyst estimates, it reported a net loss of $158.6 million for the full year 2025. This annual loss likely overshadowed the positive quarterly performance, prompting a sell-off.

Additionally, the company's Q4 revenue fell compared to the prior year, indicating underlying challenges despite improved refining margins. The combination of a significant annual loss and declining revenue contributed to the negative market reaction during the session.
