Delek's Margin Capture Improves Sharply: Is This More Than a Cycle?
Delek US Holdings DK is showing that refining profitability is not being driven solely by a stronger margin environment. The company is also improving how much of that market opportunity it captures. In the second quarter, DK’s refining margin increased sharply, supported by robust distillate yields and higher throughput after the successful completion of the Big Spring refinery turnaround. Management identified stronger refining margins and higher throughput as two of the three key drivers of the sequential increase in adjusted EBITDA.
This improvement is visible in Delek’s net-capture metrics. The company’s net capture reached 65% in second-quarter 2026, up from 53.7% in third-quarter 2023, while refining margin increased from $12.57 per barrel to $25.25 over the same period. Delek also expects its Enterprise Optimization Plan to generate at least $220 million of annual free cash flow improvement, providing another lever to strengthen profitability through the cycle.

Importantly, Delek’s advantage is tied to its refinery configuration. The company has one of the highest diesel and jet yields among its peer group, while access to barrels gathered by Delek Logistics and connections to several domestic crude hubs provide procurement flexibility. These characteristics can support stronger market capture when refined-product margins remain favorable.
How Are MPC and VLO Faring?
Marathon Petroleum MPC and Valero Energy VLO also benefit from strong refining portfolios, but Delek’s improving capture rate highlights a more specific operational advantage. MPC benefits from its large and diversified refining system, while Valero Energy has a broad refining footprint and strong exposure to refined products. For DKDK--, however, higher distillate and jet yields, crude flexibility and improving refinery reliability are directly supporting market capture. Marathon Petroleum and Valero Energy remain useful benchmarks for determining whether Delek can sustain its improving economics.
Delek’s ability to improve profitability is particularly important because refining margins can be highly cyclical. A higher capture rate means the company can potentially retain more of the available market economics rather than relying entirely on an improvement in industry-wide crack spreads. This makes operational execution and refinery reliability important factors for investors to monitor.
DK Beats Peers as Valuation Stays Competitive and Earnings Estimates Rise
Delek’s shares have gained 87.6% over the past six months, outperforming Marathon Petroleum’s 85.2% rise and Valero Energy’s 80.4% increase. The latest performance data show that DK has not only kept pace with its larger refining peers but has slightly outperformed both.

Conclusion
Delek’s improving refining capture rate highlights its growing ability to capitalize on favorable market conditions. Stronger refining margins, higher throughput and improved operational reliability should support results, particularly following the completion of the Big Spring turnaround. The company’s refinery configuration, solid distillate exposure and crude-sourcing flexibility could provide additional support if refining fundamentals remain favorable.
Meanwhile, significant upward revisions to earnings estimates indicate growing analyst confidence in Delek’s earnings prospects. The company’s strong style scores, with A grades for Value, Growth, Momentum and VGM, along with its top-4% industry ranking, further reinforce the positive outlook.
