Key Points:

  • Refinery Failure Chain: Monroe leak and fire (June 16 to 25) -> refinery at 75% capacity through Q3 -> 5 to 7 cent per gallon cost drag on top of a 40% year over year fuel spike.

  • Estimate Erosion: Wall Street's Q3 consensus has fallen 10.9% in 30 days to $1.88, now below the low end of Delta's own $2.00 to $2.50 guidance range.

  • Full-Year Risk: If Bastian narrows or lowers the $6.50 to $7.50 full-year EPS guide on Friday, the analyst average of $6.00 suggests the Street has already priced in a cut.

  • Options Positioning: The market is pricing a 6.4% to 8% post-earnings move in DAL, roughly $5 to $7 on a stock trading near $83, reflecting elevated uncertainty around fuel cost absorption.

On June 25, a column of black smoke rose over Trainer, Pennsylvania. It drifted across the Delaware River into South Jersey. Chopper 6 caught it from the air. A worker was airlifted to Thomas Jefferson University Hospital with burn injuries. The plant on fire was Monroe Energy. A 190,000-barrel-a-day oil refinery. It supplies more than half the jet fuel on the East Coast. Delta Air Lines owns it.

If you hold DAL, or you own shares through JETS or XTN, that fire is your problem today. Delta reports Q3 earnings this morning before the bell. The stock is up 52% over the past year and sits near $83. Options are pricing a swing of roughly $5 to $7 in either direction. Delta's fuel shield spent the whole quarter running broken.

I don't think most people realize how Delta hedges its fuel. Most airlines buy derivatives contracts. They lock in prices months ahead. Delta does not do that. In 2012, Delta bought the Trainer refinery for $150 million. That is roughly the cost of one widebody jet. The goal was simple. Make its own jet fuel and cut costs by $300 million a year. The refinery produces about 80% of Delta's domestic supply. No contracts. No financial instruments. One plant. One location. One bet. That bet worked for 14 years.

OpenAI, Amazon, Microsoft, IBM, and AMD already have multi-billion dollar deals with it.

Wall Street projects sales will triple in 2027 alone.

Then came June. On the 16th, a process leak shut down both crude distilleries at Monroe. The plant went dark. Eight days later, crews were restarting a key processing unit. A fire broke out in a pump room. One worker was airlifted. Two more were treated for heat stress. The fire hit during the restart. A double failure. CEO Ed Bastian spoke to investors on July 10. The refinery entered Q3 at about 75% of capacity. CFO Erik Snell said the outage would have a tail into the third quarter.

Here's what worries me. The refinery didn't just break. It broke at the worst possible moment. Jet fuel spot prices hit $4.40 a gallon by late September. Brent crude touched $108. Fuel costs rose 40% over the prior year. In Q2, Delta had already absorbed the highest quarterly fuel expense in its history. Fuel prices ran 75% above the year before. Fare hikes covered only about 60% of that jump. The rest hit the bottom line. Q3 was supposed to be the quarter when the refinery earned its keep. Instead, the outage added 5 to 7 cents per gallon in extra costs on top of the 40% spike. Delta's moat became a cost amplifier.

The One Device That Could Decide The AI Race

“Whoever wins AI, wins.”

That’s how President Trump sums up America’s AI race with China.

I believe all it comes down to a radical “light-speed” technology…

Turning AI as we know it into “Accelerated AI”…

Making it 100 times faster…

And 100 times more energy efficient.

The stocks at the center of it already ripped 133%, 217%, and even 320% — in a few short months.

And it’s just getting started.

Let the money flow to you,

P.S. I believe my #1 pick could break out in a matter of days. Click here before it does.

I looked at the numbers Delta gave in July. They guided Q3 earnings at $2.00 to $2.50 per share. That assumed fuel at $3.15 a gallon. It baked in a 5-cent refinery benefit. Today the consensus sits at $1.88. Below the low end of Delta's own guidance. Estimates have fallen 10.9% in just 30 days. Zacks gives the stock a Strong Sell and expects the miss to be worse than the Street thinks. The Street does not believe Delta's own numbers.

Delta has no Plan B. European carriers hedge 60% or more of their fuel with derivatives. Delta carries no broad fuel derivatives book. The refinery is the entire strategy. When Monroe went offline, nothing stood behind it. Look at American Airlines for contrast. American does not own a refinery. American cut its 2026 earnings guidance for the second time in three months back in July. American is heading toward breakeven. Delta was supposed to be the one that was different. That was the whole thesis. I can't stop thinking about this. Delta was built to survive a fuel shock. It is sinking right alongside the airline with no protection at all.

Nobody knows what Ed Bastian will say about Q4 guidance this morning. The full-year range is $6.50 to $7.50 per share. Analysts already project $6.00 on average. If he narrows or lowers that range, the entire airline sector reprices before lunch. I get it. If you bought DAL for the refinery story, it made sense. A structural edge no other U.S. airline could match. It made sense right up until a pump room caught fire on June 25.

I keep coming back to one number. $150 million. That is what Delta paid for the only asset standing between it and a 40% fuel cost spike. The price of one airplane. Fourteen years later, that single plant is Delta's entire fuel hedge. No backup. No second line. It caught fire during the worst fuel shock since the Iran conflict began. And there was nothing behind it.

This morning, before the bell, Ed Bastian will step up and explain what happened to the numbers. But the answer was already in the air three months ago. A column of black smoke rising over Trainer, Pennsylvania. Drifting across the Delaware. Visible from two states. Delta's only shield was burning.

More on this tomorrow.
