Question · Q4 2025
Paul Chang followed up on Valero's refinery utilization rates, asking if the company now believes it can achieve better maximum full-cycle utilization than the historical 94%-95% due to improved operations, and if the entire industry is also improving, along with any noticeable downtime from the recent winter storm.
Answer
Gary Simmons, EVP and COO, confirmed a record year for mechanical availability in 2025, which should lead to better utilization, but found it difficult to quantify. He noted that strong margins and moderate temperatures allowed higher utilization in Q4 2025, but December's 95.4% is unsustainable. He also stated that Valero fared well during the winter storm, with no material downtime impacting the quarter's guidance.
