The S&P 500 energy sector reports Q1 2026 earnings this week and the cluster will tell investors how Hormuz tension translated into actual cash flow at the integrated oil majors. Exxon Mobil reports Friday May 1 before the open, Chevron reports Friday May 1 before the open, and ConocoPhillips reports Thursday May 7 before the open. Halliburton and Schlumberger reported earlier this month and beat consensus on services revenue, suggesting upstream activity held through the quarter. The full sector is currently expected to report a year-over-year earnings decline of 0.1 percent, the third largest decline of the eleven S&P sectors, according to FactSet's preview published April 21.
The headline misleads. Brent crude opened the quarter at $57.42 per barrel and closed at $101.38, an increase of 77 percent. The average price for the quarter was $72.67, only 1.8 percent above the Q1 2025 average of $71.38. The math means that even though headlines for most of March focused on triple-digit oil, the quarter's actual revenue base was barely above prior year. The price spike happened in the back half. Q2 will capture the full benefit if the Hormuz risk premium holds. Analysts have already moved Q2 sector earnings expectations to 71 percent year-over-year growth, with 42.1 percent expected for Q3, 40.9 percent for Q4, and 37.6 percent for Q1 2027.
Exxon is the swing vote on the sector print. The company is the largest contributor to the expected Q1 sector decline. Analysts cut Exxon EPS estimates from $1.91 to $1.31, a 31 percent reduction reflecting weaker downstream margins in February and a planned maintenance outage at the Beaumont refinery. If Exxon is excluded from the calculation, the energy sector would post a year-over-year earnings growth of 12.5 percent. The Friday print therefore matters more for sector psychology than the underlying fundamentals suggest. Chevron's Permian production guidance and capital allocation update will move the stock more than the headline EPS number.
The two sub-industries inside the sector that are expected to grow earnings year-over-year are oil and gas refining and marketing, which is forecast to swing from a $125 million loss in Q1 2025 to $1.9 billion in profit, and oil and gas storage and transportation, which is expected to grow earnings 27 percent. Refining margins were the surprise of the quarter. Crack spreads in the Gulf Coast averaged $24.50 per barrel in March, up from $14.10 in March 2025, driven by tight inventory and the closure of two East Coast refineries during the prior 12 months. Pipeline operators including Enterprise Products Partners and Energy Transfer benefited from increased Permian throughput and stronger NGL demand.
Valuation has reset. The S&P 500 energy sector trades at 14.8 times forward earnings as of Friday's close, a 31 percent discount to the broader S&P 500's 21.5 times. The dividend yield on the sector ETF, XLE, sits at 3.4 percent against the S&P 500's 1.3 percent. Free cash flow yield on Exxon is 7.8 percent, on Chevron 6.9 percent, and on ConocoPhillips 6.4 percent based on consensus estimates. The combination of below-average valuation, above-average yield, and an earnings growth runway over the next four quarters has drawn capital back to the sector. XLE is up 9.1 percent year to date through Friday, ahead of the S&P 500's 6.4 percent return.
The geopolitical premium is the variable that breaks any model. Iran has held production around 3.4 million barrels per day through the quarter, despite the U.S. naval posture in the Strait of Hormuz and the December 2025 U.N. Security Council resolution. The market has priced in a 22 percent probability of a complete Hormuz disruption in 2026 according to options data on Brent futures. A full disruption would push Brent toward $130 and pull energy sector earnings to growth rates above 100 percent. The base case priced into current models is partial, intermittent disruption with Brent settling between $85 and $95 for the year. Last week's announcement that Iran is collecting tolls from tanker traffic transiting Hormuz has lifted the floor on the geopolitical premium.
What investors should watch in the prints. Exxon's downstream segment will tell you whether February's margin compression was structural or transient. Chevron's Permian breakeven and 2026 capex guidance will signal U.S. shale discipline. ConocoPhillips' Alaska commentary will indicate the Willow project ramp pace. Across the cluster, the dividend and buyback announcements will matter more than EPS surprises. The sector has rewarded capital return more than production growth since 2022 and management teams know it.
