Valero's refining windfall is piling up as cash, nearly twice its own target

Valero Energy earns its living on the gap between what crude oil costs and what gasoline, diesel and jet fuel sell for. In the September 2026 quarter that gap widened sharply: the refining margin per barrel processed was $39.24, against $13.14 a year earlier. Operating income rose to $9.1 billion, about six times the year-earlier figure, calculated from the reported results. Much of that money has not left the company. Cash stood at $9.8 billion at the end of September, nearly twice the top of the $4 billion to $5 billion range Valero says it aims to hold over the long term.

The jump came from price, not from more barrels. Valero processed fewer barrels a day than a year earlier, largely because its Benicia refinery on the West Coast is now idle, so nearly all of the gain came from earning more on each one. The chief operating officer, Gary Simmons, said management had high confidence that today's wide spread would last. He also named the condition that would narrow it: "if for some reason, crude runs up, I do think that it could cause some compression of refinery cracks."

The windfall arrived as cash. Adjusted operating cash flow, a measure that leaves out swings in working capital and the share of the Diamond Green Diesel joint venture belonging to Valero's partner, was $7.3 billion last quarter. The company returned a little over half of it through dividends and share buybacks, roughly $3.8 billion when that rounded ratio is applied to the cash flow. About half of what was left went into the bank: cash rose by about $2.0 billion in the quarter, and by about $5.2 billion since December, calculated from the balance sheets.

The share handed back has slipped, from 66% of adjusted operating cash flow three quarters earlier to 52% last quarter, the lowest of those four quarters. The dollars handed back have not shrunk: Valero returned $2.6 billion in the quarter before and more last quarter; the ratio fell because the cash coming in grew faster than the amount handed back, as adjusted operating cash flow climbed from $4.5 billion in the quarter before.

Nor is the money being pushed into new projects. Valero still expects capital investment of about $2 billion for this year, up from the $1.7 billion it guided at the start of the year; the higher figure includes repairing a damaged unit at its Port Arthur refinery. The chief executive, Lane Riggs, said the large cash balance would not change the hurdle rates and return targets the company has long used to judge projects.

The dividend will not absorb the surplus either. The chief financial officer, Homer Bhullar, described it as "a one-way ratchet": once raised it is defended, so increases will come at a steady pace, with buybacks left as the flexible way to return the rest. Buybacks have already cut the diluted share count to 285 million from 309 million a year earlier.

Bhullar explained the cash pile as a buffer. When commodity prices fall fast, he said, working capital usually soaks up cash, and the company wants to keep paying shareholders through such a fall. Working capital already drew on cash last quarter. He also said that "all the excess cash we're accumulating will ultimately be directed towards our owners."

Management ties the pace of those returns to volatility: it says it can be more aggressive if volatility returns and as cash moves back toward its long-term target. While refining margins stay near last quarter's level, paying out a little above half of cash flow adds to the balance each quarter, as it did last quarter. If crude rises and the spread narrows, as Simmons allowed it could, cash flow would shrink; management says the cash it holds above its target will still go to shareholders over time, whether margins stay strong or not. The buffer it describes is for a different risk, a sharp fall in commodity prices that drains working capital.
