SAN ANTONIO, August 19, 2026, 12:58 a.m. CDT — U.S. markets have finished trading.
- The refining crack for U.S. diesel hit an all-time high of $102.20 per barrel on August 17.
- Valero ended Tuesday at $350.05, finishing 0.27% under its 52-week peak.
- Analysts have set an average target price of $320.67, representing an 8.4% discount to the last close.
Valero Energy Corporation NYSE:VLO closed Tuesday just below an all-time high, after the U.S. diesel crack surpassed $100 per barrel for the first time. The surge is driving exceptionally strong short-term refining margins, but it also results in only a thin valuation buffer.
The diesel crack climbed to $102.20 on Monday, indicating the difference between diesel futures and West Texas Intermediate crude prices. U.S. distillate stocks were at 107.1 million barrels on August 7, the lowest seasonal figure since 1996.
The squeeze is now worldwide. In July, refinery throughput averaged 80.9 million barrels per day, nearly 5 million less than the same period last year. NitrolOil chief executive Shohruh Zukhritdinov stated: “The U.S. is producing more diesel, not less, and yet the crack is still above $100.” Reuters

Valero reported a surge in adjusted refining operating income for the second quarter, climbing to $4.44 billion from $1.27 billion. While throughput rose just 1%, improved margins delivered the primary boost. The results highlight how swiftly wider spreads can feed into earnings.
| Refining indicator | Q2 2026 | Q2 2025 | Change |
|---|---|---|---|
| Margin per barrel | $23.62 | $12.35 | +91% |
| Adjusted operating profit per barrel | $16.56 | $4.78 | +246% |
| Throughput at refineries | 2.950m bpd | 2.922m bpd | +1% |
| Gulf Coast ULS diesel minus Brent | $43.52/bbl | $14.79/bbl | +194% |
The diesel crack on Monday, at $102.20, was roughly 2.35 times Valero’s Gulf Coast diesel benchmark for the second quarter. These metrics are based on different crude references, making their comparison directional rather than exact. Nevertheless, it highlights the extent of the current market dislocation.
The composition of profits widened. Renewable diesel posted an operating profit of $717 million. Ethanol earnings increased nearly six times. Chief executive Lane Riggs said the quarter was “driven by excellent operations and commercial execution across all three of our business segments.” Valero
| Segment operating result | Q2 2026 | Q2 2025 | Year-on-year change |
|---|---|---|---|
| Adjusted refining profit | $4.44bn | $1.27bn | +$3.17bn |
| Renewable diesel profit | $717m | -$79m | +$796m |
| Ethanol profit | $318m | $54m | +$264m |
Valero’s cash flow supports capital returns. The company generated $5.6 billion in operating cash flow for the quarter, distributed $2.6 billion to shareholders, and reported $7.9 billion in cash at the end of June. Net debt to capital stood at 11%.
Questions over valuation have intensified. Valero finished trading at $350.05, just $0.95 shy of its highest level from the past 52 weeks. Of fifteen analyst opinions gathered over the last three months, nine are buys while six recommend holding. However, the consensus price target stands at $320.67, pointing to an expected drop of 8.4%.
| Analyst | Firm | Rating | Target | Date |
|---|---|---|---|---|
| Neil Mehta | Goldman Sachs | Buy | $365 | Aug. 3 |
| Sam Margolin | Wells Fargo | Buy | $356 | July 31 |
| Manav Gupta | UBS | Buy | $355 | July 31 |
| Jason Gabelman | TD Cowen | Hold | $350 | Aug. 3 |
| Nitin Kumar | Mizuho | Hold | $300 | Aug. 4 |
The difference indicates investors are ahead of current forecasts. Goldman’s $365 high-end target implies a 4.3% potential gain, while TD Cowen’s $350 target is about the same as the stock’s current value.
The short-term outlook continues to look favorable. On Tuesday, the energy sector advanced 1.8%, leading gains on the S&P 500, which declined by 0.69%. Valero added 0.83%. Although the company benefited from the diesel trade, it trailed other major refiners.
Risks: Rapid diesel crack compression may occur if global supply returns or demand weakens. Refinery disruptions, changes in crude prices and renewable-fuel regulations could also erode earnings leverage. The stock’s closeness to its peak heightens the potential for disappointment.
For investors, the key question is how long margins will remain high. Valero does not require crack spreads to stay at $100 indefinitely. The company only needs strong margins to continue long enough for earnings forecasts to align with its current share value.
