Primo Brands added about $68 million of operating income, nearly as much as the $66.1 million of sales it added, during the three months ended June 30. That is the headline version of the latest report: modest top-line growth, a much larger profit jump, and shares at $23.32 after a 4.5% move at the latest close.
The less tidy detail is where the profit came from. Revenue rose 3.8% to $1.8 billion, but gross profit increased only 1.4% and gross margin fell 0.7 percentage points to 30.5%. The operating margin jump, from 6.5% to 10.0%, was helped by a sharply smaller integration and restructuring bill.
Primo described that comparison plainly:
"During the three months ended June 30, 2026, acquisition, integration and restructuring expenses were $10.0 million, a decrease of $39.7 million, as compared to the three months ended June 30, 2025, primarily due to lower integration costs incurred during the current year period compared to the prior year period as integration efforts begin to wind down as well as net restructuring gains in the current year period driven primarily by gains associated with the sale of facilities compared to net restructuring costs in the prior year period primarily driven by facility charges."

That is a meaningful change in the cost base, but it is not the same thing as selling 4% more water at a 4% better margin. The company reported $10.0 million of these expenses in the latest three months, down from the comparable period's $49.7 million.
The sales mix supplied some lift. Regional spring water grew 4.1%, while premium water climbed 30.5%, adding $26.7 million. The smaller lines were mixed, and the divested coffee business reduced sales by $6.9 million.
Meanwhile, the gross-margin line faced a different set of receipts. Primo said:
"During the three months ended June 30, 2026, cost of sales were $1,247.5 million, an increase of $58.3 million, or 4.9%, as compared to the three months ended June 30, 2025, primarily due to increased transportation related costs of $42.6 million and increased depreciation and amortization of $8.4 million, partially offset by a decrease of $6.8 million related to lower non-recurring integration related costs incurred in the current year period and a decrease of $5.2 million related to the divested coffee business."

The result was an operating-income surge alongside a narrower gross spread, with the operating improvement carrying a clear contribution from work that management says is winding down.
The balance-sheet and investment numbers add another layer. Capital spending rose 58.6% to $85.5 million, while inventory increased 3.5% to $257.0 million and accounts receivable fell 2.0% to $575.4 million. Those are reported movements, not explanations, but they add balance-sheet and investment context.
Primo's own annual results show how much the margin picture has moved around: revenue reached $6.7B in 2025, while operating margin was 6.5%. The latest three-month figure is higher, though the filing's most immediate explanation is lower integration and restructuring expense rather than a widening gross margin.
That distinction matters beside the stock's valuation. Primo has a market cap of $8.7B, net debt of $4.7B, and a reported P/E of 145.5x. At that price tag, the durability of the operating improvement matters at least as much as the headline earnings jump.
The specific number to compare in Primo's next quarterly report is the $10.0 million acquisition, integration, and restructuring expense, which gives the latest operating-profit lift a clean reference point.
