Pague Menos admits its digital checkout choked on GLP-1 pen demand in Q2

On the August 4, 2026 earnings call, Pague Menos CEO Jonas Marques did something unusual for a Brazilian retailer: he said the company had erred. 'We had the lowest growth level of the quarter... We could have done better, we made a mistake, the digital operation was overloaded,' he told analysts, explaining April-June results in which the chain lost part of its sales of GLP-1 weight-loss pens — a category where most volume happens online because that is where the discounts are.

The failure was technical and specific: the problem was identified in a Vtex system update at the moment of product payment. Pague Menos brought in its platform partner Vtex to help stabilise the operation through a 'war room', and the fault was found when Marques himself ran a simulated purchase of a pen and hit the broken checkout. The cost showed in the mix: the GLP-1 category contributed 6.1% of company growth in the quarter, versus 13.8% a year earlier and 7.9% in the first quarter — with management also citing a high base of comparison from last year.

By July the indicator had recovered, with pens' weight in total sales growing again. The wider quarter was healthy — gross revenue up 9.3% to R$4.3 billion, net income of R$71.2 million against R$50.3 million a year before, EBITDA margin up from 6.1% to 6.5% — and the market read the results that way, sending the stock up more than 7% on the day. Marques still found room for colour: Ozivy pens were scarce and sold out fast, price cuts doubled sales, and 'thank God we are far from Paraguay', away from irregular imports.

The company put the failure on the record itself, on the earnings call, with the CEO narrating his own broken test purchase — a rare admission in Brazilian retail.

The broken step was payment at checkout on a platform update, the one moment where a discount-hunting GLP-1 customer becomes a lost sale.

GLP-1 pens are exactly the kind of viral, price-sensitive category that punishes downtime: demand was there and went elsewhere for a quarter.

The fix — a war room with Vtex — shows the dependence of retailer growth math on a third-party commerce platform's release cycle.

Surging demand for a hero category is exactly when infrastructure fails: test the purchase path as a customer, and put the platform vendor in a war room before the quarter's numbers show it for you.

Management said the GLP-1 contribution to growth improved in July 2026, with the category's weight in total sales rising again; the material reports no further outage.
