Keurig comes up short

Keurig Dr Pepper reported revenue in the quarter up 2.3% to $3.89 billion, which was short of estimates at $3.93 billion.

Sales were up 3.1% on a constant-currency basis, benefiting from a 3.5% increase in volume and sales mix, though prices fell 0.4%. The U.S. soft drink business was strong with sales up 5.3% to $2.4 billion, though U.S. coffee sales were down 3.6% to $1 billion.

Further down the income statement, the company said adjusted operating income was up 7.5% to $1.05 billion. Adjusted earnings per share (EPS) rose from $0.48 to $0.51, matching estimates.

The bigger news seemed to be the company's acquisition of Ghost, an energy drink business that gives it exposure to growth in beverages.

It agreed to pay $990 million for a 60% stake in the business and will purchase the remaining 40% in 2028 at a valuation that's based on the Ghost's 2027 financial performance.

Management said the deal would be neutral to modestly accretive to EPS starting in 2025.

What's next for Keurig Dr Pepper

Keurig Dr Pepper reaffirmed its full-year guidance calling for constant-currency sales in the mid-single-digit range, and adjusted EPS in the high-single-digit range.

While the financial results were mostly fine, the Ghost acquisition seems to be giving investors pause as it comes at a time when the energy drink category is slowing.

Keurig is paying a price-to-sales multiple of 3 for Ghost, which is similar to the valuation that Keurig trades at. Keep an eye on the integration in the coming quarters.
