SAN ANTONIO, August 17, 2026, 12:18 CDT — U.S. cash markets have begun trading.
- On August 10, U.S. diesel margins hit an all-time high of $93.84 per barrel.
- Valero’s stock has climbed approximately 98% this year, exceeding analyst projections.
- The current earnings case is propelled by refinery shortages, not elevated crude prices.
Valero Energy Corporation NYSE:VLO faces an uncommon challenge this week. On August 10, the U.S. ultra-low-sulfur diesel crack hit an all-time high at $93.84 a barrel. This figure stands at 2.16 times the Gulf Coast diesel spread Valero reported for the second quarter.
The spread is more significant than crude’s movement. Brent closed at around $88.58 on Monday, nearly 30% under its peak during the Iran conflict. However, refinery outages and bottlenecks continue to limit supplies of diesel, jet fuel, and gasoline.
Refinery stocks have outperformed since the war began, driven by limited supply. Shares of Valero, Marathon Petroleum Corporation NYSE:MPC, and Phillips 66 NYSE:PSX have jumped an average of 66%. In comparison, oil majors advanced about 8% during the same timeframe.
| Refining-market measure | Latest verified reading | Investor signal |
|---|---|---|
| Brent crude | $88.58 a barrel | Remains far from the peak seen during wartime |
| U.S. ultra-low-sulfur diesel crack | $93.84 a barrel, August 10 | Unprecedented margin for product |
| Valero Gulf Coast diesel less Brent | $43.52 a barrel, Q2 2026 | Threes times greater than the spread a year ago |
| Middle East processing gap | 2.2 million bpd expected in Q3 | Deficit in product remains ongoing |
| July export decline | 1.3 million bpd year on year | About 20% of total seaborne product commerce |
Europe displays a similar disparity. Gasoil stocks are 24% under their five-year average. Jet-fuel inventories are down by 39%. The premium of European diesel to Brent has climbed above $70 a barrel, compared to about $25 at the beginning of the year.
Valero posted net income of $3.7 billion in the second quarter, an increase of approximately 418% compared to the prior year, reflecting only a portion of the expanding margin. Refining operating income rose more than threefold.
| Valero measure | Q2 2026 | Q2 2025 | Change |
|---|---|---|---|
| Net income attributable to Valero | $3.7 billion | $714 million | Increase of about 418% |
| Diluted earnings per share | $12.62 | $2.28 | Rise of about 454% |
| Refining operating income | $4.47 billion | $1.27 billion | Up approximately 253% |
| Refining throughput | About 3.0 million bpd | About 3.0 million bpd | Remained close to unchanged |
| Stockholder returns | $2.6 billion | $1.0 billion | Increase of about 160% |
Chief Executive Lane Riggs said, “Our strong results reflect the discipline and consistency of our operational and commercial execution.” At the end of June, Valero reported $7.9 billion in cash alongside $9.1 billion in debt, with net debt accounting for 11% of total capital.
The balance sheet provides flexibility for management to return cash to investors. Valero approved a fresh $5 billion share buyback program, having already distributed $2.6 billion in the quarter. Shareholder returns for the second quarter totaled $6.3 billion at Valero, Marathon and Phillips 66, up from $2.6 billion in the same period a year ago.
TD Cowen analyst Jason Gabelman projects that Valero and Marathon might each buy back about 20% of their market capitalization from the third quarter up to 2027. This outlook is based on expectations that solid margins will continue and that both firms will maintain their focus on share repurchases.
Valero’s valuation is now considered riskier. Shares ended at $342.92 on August 13 following four consecutive advances. This price is higher than all but Goldman Sachs’ $357 price target among the latest analyst recommendations.
| Broker | Most recent rating | Target price | Date issued |
|---|---|---|---|
| Goldman Sachs | Buy | $357 | July 22, 2026 |
| Mizuho | Hold | $289 | July 2, 2026 |
| Barclays | Buy | $279 | July 1, 2026 |
| Morgan Stanley | Hold | $255 | June 12, 2026 |
| UBS | Buy | $280 | June 11, 2026 |
The main issue for the market remains how long current conditions will last. Morgan Stanley projects a 2.5 million barrels per day increase in refined-fuels demand over three years, while net refining capacity might only rise by 1.2 million barrels per day. This gap could sustain higher-than-normal profits for complex U.S. refineries.
There is limited flexibility for near-term operations, with U.S. refiners operating at unprecedented levels. Energy Secretary Chris Wright stated Monday he plans to speak with refiners about increasing production, as average gasoline prices rose above $4.06 per gallon.
Jet fuel may drive the next margin increase. Chief Operating Officer Gary Simmons noted the absence of its support in the early third quarter. “I suspect we’ll start to see jet strengthen as we move throughout the quarter,” he said.
Risks: Swift narrowing of cracks is possible if a lasting ceasefire is reached, refinery capacity returns, or travel and freight demand softens. High utilization rates also heighten the risk of outages. Shares currently trade above the majority of analyst price targets, meaning even robust earnings may not keep the rally going.
Crude now offers less clarity for investors. Key indicators include product stockpiles, refinery disruptions, and diesel crack spreads. Valero’s strategy will hinge on whether the $93.84 surge represents a top, or signals a lasting shift in margins.
