PBF Energy Inc (PBF) saw its stock plummet 5.18% during intraday trading on Friday, as investors reacted to news about operational challenges at one of its key refineries. The significant drop comes amid a crucial period for the company, which recently released its Q2 earnings report.

The main factor contributing to the stock's decline appears to be the announcement regarding PBF Energy's Martinez refinery. The company stated on Thursday that the refinery was only partially operational and expected to run at a reduced capacity until repairs are completed. PBF Energy plans a full restart of the remaining units by the end of 2025, indicating a prolonged period of reduced output from this important facility.

This operational setback could potentially impact PBF Energy's production volumes and financial performance in the coming quarters. Investors seem to be pricing in the possibility of lower revenues and increased costs associated with the refinery repairs, leading to the sharp decline in the company's stock price.
