The market reaction was less about demand and more about timing. Airlines still want Airbus jets, but the company is struggling to turn a record order book into cash on schedule, and those are not the same thing.

Airbus added 398 net orders in the first quarter of 2026, pushing its backlog past 9,000 aircraft, including 20 A350 freighters ordered by Atlas Air, Leeham News reported in April. That is a healthy pipeline by any normal standard. It just does not pay the bills until the handover happens.

The numbers from the quarter were ugly enough on their own. Airbus Commercial’s adjusted EBIT fell to €81 million on €8.426 billion in sales, which is a margin of less than 1%, Leeham News reported in April. A backlog can be a beautiful thing on a slide deck. It is less charming when it is sitting in the warehouse.

Back in January, then-Airbus Commercial CEO Christian Scherer said the A350’s delivery stagnation was “not a lack of demand,” blaming fuselage section problems at the supplier formerly known as Spirit AeroSystems, Leeham News reported in January. That matters because the latest delay report does not point to a lost market. It points to a company that keeps tripping over its own supply chain.

There is no single bottleneck here, which is part of the problem. Guillaume Faury described the situation in late April as a “desynchronization between production and delivery,” a neat phrase for a messy business.

He pointed to fuselage panel quality issues, an administrative delay that held up delivery of nearly 20 aircraft to China, Pratt & Whitney engine shortages, a seating shortfall, and broader disruption from tariffs and conflict, Leeham News reported in April. That is a lot of friction at once. Too much, in fact, for a smooth production ramp.

The engine issue is the biggest constraint on the A320 program. Faury said Pratt & Whitney “remains the key pacer of our A320 ramp-up trajectory and deliveries for this year and for next year,” covering both 2026 and 2027, Leeham News reported in April. Airbus has leaned on additional CFM LEAP engines to help, but Faury said that still was “not enough to offset the significant number of missing engines.”

The A350 problem has been hanging around longer. Airbus said in its Q1 2025 results press release that Spirit AeroSystems issues were “currently putting pressure on the ramp-up of the A350 and the A220.” More than a year later, that pressure has not gone away.

That is why the delay story has legs. Engines, structures, interiors, logistics and geopolitics are all leaning on the same machine at the same time. There is no one lever to pull and be done with it.

The latest report matters because it arrives on top of a first quarter that was already under strain. Investors are not being asked to imagine trouble. They are looking at it in the numbers.

Airbus generated €300 million in group-wide adjusted EBIT on €12.651 billion in revenue in Q1 2026, compared with €624 million on €13.542 billion a year earlier, Leeham News reported in April. That was a 7% drop in revenue and a 52% collapse in earnings.

Free cash flow was negative €2.422 billion for the quarter, Leeham News reported in April. CFO Thomas Toepfer said Airbus built about $5 billion of inventory, almost $1.5 billion more than a year earlier, which helped explain the cash drain. Aircraft sitting around look impressive only to accountants and warehouse staff.

Airbus is still holding its full-year guidance steady: 870 commercial deliveries, about €7.5 billion in adjusted EBIT and around €4.5 billion in free cash flow before customer financing, Airbus said in April. That target now depends on a sharp pickup in the remaining three quarters, and the latest delay report makes that harder to take on faith.

The next few months now matter far more than the first quarter. Airbus has kept its target of a monthly A350 production rate of 12 aircraft by 2028, Airbus said in April, but the near-term delivery trend is heading the wrong way.

Pratt & Whitney will be the variable to watch on the A320 side. Faury’s description of the engine maker as the “key pacer” for deliveries through 2026 and 2027 means any improvement, or any further slip, will feed straight through to Airbus output, Leeham News reported in April.

For now, the market is doing what markets do when the numbers and the guidance stop lining up. It is questioning how much improvement is left to come, and how quickly Airbus can deliver it. The next mid-year delivery update will tell investors whether this is a bad quarter, or the start of a more stubborn problem.
