Key Highlights

● Higher fuel costs drove the cut.

● Third-quarter results were mixed.

SkyWest (NASDAQ:SKYW) sank on Friday, October 30, 2026, after the regional carrier lowered its 2026 earnings-per-share outlook, citing higher fuel costs. The company also reported mixed third-quarter results against a backdrop of rising fuel prices, according to market data. The stock was among the steepest decliners on the FT Wilshire 5000, though reports differed slightly on the size of the move.

SkyWest, based in St. George, Utah, is one of the largest regional airlines in the United States. It operates flights on behalf of major carriers including United Airlines (NASDAQ:UAL), Delta Air Lines (NYSE:DAL), American Airlines (NASDAQ:AAL) and Alaska Airlines, flying smaller jets on shorter routes that feed passengers into its partners' networks.

The oil problem

Fuel is one of the largest costs for any airline, and prices have climbed sharply. On Friday, West Texas Intermediate crude for December delivery rose $2.12 to $104.12 a barrel, and Brent Crude settled at $113.43, according to market data. Brent's four-year high of $116.72 came on October 23, according to Trading Economics.

The rise has been driven by tensions involving Iran. Reports said the U.S. could resume strikes on Iran, there were tanker incidents in the Strait of Hormuz, and Iran claimed vessels had been struck by mines. A Ukrainian strike on a refinery in Samara, Russia, added to Supply worries. President Trump said the Iran war is "going to end soon," according to market data, but oil markets remained tense.

When fuel costs rise faster than an airline can adjust, profits come under pressure. For SkyWest, the higher bill was enough to prompt a cut to its full-year Earnings outlook. The company's capacity-purchase arrangements with its major-airline partners shape how much of the cost it bears, but the outlook cut showed the pressure was still meaningful.

Mixed results

The company's third-quarter results were mixed, according to market data, with the higher fuel prices weighing on the quarter. Detailed figures were not included. The combination of a mixed quarter and a lower outlook left investors with little to cheer.

A tough day all around

SkyWest's decline came on Wall Street's worst day since June. The S&P 500 fell 140.32 points to 7,580.07, the Dow Jones Industrial Average lost 572.25 points to 51,770.31 and the Nasdaq Composite dropped 747.73 points to 25,437.00, its worst day since June 5. The Russell 2000 slid 47.37 points to 2,811.84. Closing levels for the FT Wilshire 5000 were not available.

Industrials, the sector that includes airlines, was among the weakest groups, second only to technology, which was hammered after Intel (NASDAQ:INTC)'s weak outlook and cash-burn warning. Energy was the best-performing sector as oil climbed, with Exxon Mobil (NYSE:XOM) and Chevron (NYSE:CVX) briefly touching record highs after reporting strong refining results.

The rise in oil also fed into worries about inflation. Federal Reserve Chair Kevin Warsh said this week, "But Inflation remains elevated," and markets moved to price in a rate hike in December. Higher rates can weigh on travel Demand and raise borrowing costs for airlines that finance aircraft.

What to watch

The path of oil prices will be the biggest Factor for SkyWest. Any easing of tensions involving Iran or the Strait of Hormuz could relieve fuel costs, while further escalation could add to them. Vice President JD Vance sent a letter to Tehran about reviving talks, but Iran said it won't soften its position, according to Trading Economics.

Investors will also watch for updates on travel demand heading into the holiday season. The midterm elections on Tuesday, November 3, and the October jobs report on Friday, November 6, could also influence the broader market.
