Analysis: a capital return proposed after a 13.3 point fall in margin

The sequence matters more than either announcement alone. In the space of five days Aeroméxico had the legal basis of its largest commercial partnership restored and then said it would ask shareholders for authority to buy its own stock. Both statements address the same question a company nine months past its listing has to answer, which is whether the cash on its balance sheet is committed to defending the business or is genuinely surplus.

On the reported numbers, the case for surplus rests on liquidity rather than on earnings. Adjusted EBITDAR fell 35.5% year on year and the margin lost 13.3 percentage points, so the proposal follows a quarter in which the adjusted EBITDAR margin was 17.9%, against 31.2% a year earlier. What did not weaken is cash, which rose 114.3 million dollars year on year while the company added no financial debt, and leverage, which ended below 2.0 times adjusted net debt to EBITDAR. A 100 million dollar annual ceiling sits inside the 114.3 million dollar year on year cash increase.

The guidance is the other half of the argument. Management expects adjusted EBITDAR margins of 26.5% to 29.5% in the third quarter and 28.0% to 31.0% in the fourth, against 17.9% in the second, on a more favourable fuel price assumption of 3.2 dollars and 3.0 dollars per gallon. A buyback authorisation sought now would be exercisable through that expected recovery. The authorisation is a ceiling, not a commitment, and nothing in the release obliges the company to spend it.

What a careful reader would watch next is the meeting notice, since it must carry the terms the press release omits, and the fuel and currency assumptions behind the guidance, since a 79.9% rise in fuel expense was enough to halve the margin in a quarter when revenue set a record. The Delta ruling removes a legal risk but does not by itself add revenue, and the company said it is still reviewing the opinion.

What the documents say

Grupo Aeroméxico, S.A.B. de C.V. (NYSE: AERO) said on August 24, 2026 that it intends to put a share repurchase programme of up to 100 million dollars a year to an upcoming shareholders’ meeting. The airline furnished the announcement to the United States Securities and Exchange Commission on Form 6-K the same day, under commission file number 001-42931. It would be the group’s first standing capital return mechanism since its initial public offering, whose final prospectus is dated November 5, 2025.

What the proposal says and what it leaves open

The programme would be established in accordance with the applicable provisions of the Mexican Securities Market Law and the company’s bylaws. Subject to approval, Aeroméxico would be authorised to repurchase its common shares from time to time, at the company’s discretion, depending on market conditions, capital allocation priorities, available liquidity, legal and regulatory requirements and other relevant factors. The stated objective is to return value to common shareholders and to holders of the company’s American depositary receipts, which trade in New York under the same symbol as the shares do on the Mexican exchange.

Four things the announcement does not contain are worth naming, because each is normally the operative detail of a buyback. It does not fix a date for the shareholders’ meeting. It does not say whether the authorisation would be annual and renewable or a single approval. It does not set a floor or ceiling price, or a maximum share count. And it does not say whether purchases would be executed in Mexico City, in New York against the depositary receipts, or both. The release is an intention to propose, not a programme.

The quarter behind the proposal

Aeroméxico reported second quarter results on July 13, 2026. Total revenue was a record for a second quarter at 1,479 million dollars, up 12.6% from 1,314 million dollars, on capacity that grew 1.9% measured in available seat miles. For the first half, revenue was 2,821 million dollars against 2,498 million dollars.

Profitability moved the other way. Total fuel expense was 493.8 million dollars, a 79.9% year on year increase, and Chief Executive Andrés Conesa put the fuel headwind at roughly 30 million dollars against guidance. Adjusted EBITDAR fell 35.5% to 264.2 million dollars, taking the margin to 17.9% from 31.2%, a fall of 13.3 percentage points. Operating income was 67.9 million dollars at a 4.6% margin. For the half, adjusted EBITDAR was 600 million dollars against 729 million dollars, a margin of 21.3% against 29.2%.

The balance sheet is where the buyback proposal connects. Cash and cash equivalents stood at 1.0 billion dollars at June 30, 2026, 114.3 million dollars higher than a year earlier and 12.5 million dollars above the level at the end of 2025, which the company said was achieved through operating cash generation without incurring additional financial debt. Including a 200.0 million dollar revolving credit facility, total liquidity was 1.2 billion dollars, or 21.8% of revenue over the last twelve months. Total adjusted net debt to EBITDAR ended the quarter below 2.0 times.

Guidance points to a recovery in margin. The company expects full year revenue of 6.05 billion to 6.12 billion dollars, up 13.0% to 14.0%, with an adjusted EBITDAR margin of 24.0% to 26.0% and an operating margin of 11.0% to 13.0%. For the third quarter it guides to an adjusted EBITDAR margin of 26.5% to 29.5%, and for the fourth quarter 28.0% to 31.0%. Those figures assume an average all in fuel price of about 3.2 dollars per gallon in the third quarter and 3.0 dollars in the fourth, and exchange rates of 17.5 and 17.6 Mexican pesos to the dollar.

A court ruling four days earlier

On August 20, 2026 Aeroméxico announced that the United States Court of Appeals for the Eleventh Circuit had ruled in favour of the airline and Delta Air Lines and vacated the United States Department of Transportation order that terminated approval of the Aeroméxico and Delta joint venture and its antitrust immunity. The company said the joint venture and its immunity remain in effect, and that it was reviewing the opinion and potential next steps with Delta and its legal advisers.

The immunity at issue is granted under United States law. Section 41308 of title 49 of the United States Code allows the Secretary of Transportation, as part of an order under section 41309 or 42111, to exempt a person affected by that order from the antitrust laws to the extent necessary to proceed with the approved transaction, and requires that exemption where an order under section 41309 approves an agreement on the findings that section demands. Immunity is therefore an attribute of a departmental order rather than a standing right, which is what made the vacated termination order consequential.
