Investing.com -- Coca-Cola (NYSE: KO) shares jumped 3.19% following the company's first quarter results, which showed volume growth ahead of expectations and raised full-year earnings guidance.

The beverage giant reported 3% unit case growth and 5% organic sales growth, exceeding consensus estimates by 100 basis points. Concentrate sales grew 10% organically, benefiting from six additional selling days in the quarter. The company raised its fiscal year earnings per share guidance by 100 basis points, attributed to tax benefits.

First quarter earnings per share beat consensus estimates by 6%, while profit exceeded expectations by 2%. However, gross margin came in 80 basis points below consensus, and operating margin missed by 10 basis points.

Morgan Stanley analysts noted, "Net, the quarter should instill continued confidence in the Coke story, even with a higher bar given a premium valuation vs peers."

The results highlight Coca-Cola's sustained organic sales growth outperformance compared to consumer packaged goods peers. The company's ability to raise full-year guidance stands out in the CPG sector, where most peers are expected to lower forecasts due to higher costs following recent tariff developments.
