Soft beer volumes get blamed on the consumer. Deep in the 10-K footnotes, a single distributor now controls 27.5% of sales and 22% of accounts receivable ($STZ).
BY MANISH T. · BREAKOUTBULLETIN · AUGUST 5, 2026
When Constellation Brands’ (NYSE: STZ) beer growth slows, the explanation you hear is macro: a stretched consumer, a softer high-end. That is part of it.
But there is a structural pressure the headline numbers don’t show, and it sits in plain sight in the notes to the financial statements – under “Significant Customers and Concentration of Credit Risk.”
What the Note Discloses
In its FY2026 10-K, Constellation disclosed that its single largest customer – the Reyes Beer Division, i.e. Reyes Beverage Group, the largest beer distributor in the United States – accounted for 27.5% of net sales. That is up from 25.4% the prior year, 25.1% before that, and 22.7% the year before. Its ten largest customers together were about 59% of net sales.
This is not a new disclosure – that is the first thing to get right. Reyes has been an above-10% customer for years; what has changed is that the concentration has climbed steadily to a new high. The company also notes these customer arrangements “may, generally, be terminated by either party with prior notice.”
The Honest Nuance Most Write-Ups Miss
Part of that rise is arithmetic, not a distributor grabbing power. In FY2026, Constellation’s net sales fell around 10% because it divested most of its mainstream wine and spirits business. Shrinking the denominator made beer – and therefore Reyes, a beer distributor – a larger slice of a smaller pie.
The same math explains why Southern Glazer’s, the wine-and-spirits distributor, dropped to 6.7% of net sales from 11.2%: that is the divestiture, not a competitive shift. Write the story as “Reyes is gaining leverage” and you overstate it.
The fresher wrinkle is on the balance sheet, not the income statement. Reyes’ share of Constellation’s accounts receivable jumped to 22% from 15%. More of what Constellation is owed now sits with one counterparty. That is a genuine, rising credit-concentration point the sales percentage alone doesn’t capture.
Why It Matters
US beverage-alcohol distribution is consolidating. When a single distributor is worth more than a quarter of your sales on an arrangement either side can end with notice, that distributor’s shelf priorities, promotional support, and payment timing carry real weight – a structural consideration the market tends to fold into the “it’s just macro” bucket.
SIGNAL VS NOISE
Noise: “Constellation beer volumes soften on a cautious consumer.” True, macro, widely discussed.
Signal: The FY2026 10-K shows one distributor – Reyes – at 27.5% of net sales and climbing, on a terminable-with-notice arrangement, with its receivables share up to 22% from 15%. Concentration, not just consumer – and rising.
WATCH · TRACK · MEASURE
Watch: next year’s “Significant Customers” note – whether Reyes crosses 30% of net sales on an organic (non-divestiture) basis.
Track: the receivables concentration line – the 15%-to-22% move is the newer signal.
Measure: beer net sales versus total, to separate genuine distributor share-gain from the divestiture mix effect.

BreakoutBulletin thesis When “it’s just the consumer” is the consensus explanation, the notes to the financials often name a second, more structural pressure – here, one distributor and a rising receivables balance.
