BellRing to launch Premier Protein soda as growth slows, costs rise

BellRing Brands is preparing to push Premier Protein into soda, a sign that protein is moving beyond the supplement aisle and into a more casual, indulgent beverage lane. The company is leaning on its biggest name as it faces heavier competition, more price-sensitive shoppers and rising input cost inflation, making the soda play look both like an offensive launch and a defensive hedge.

Premier Protein gives BellRing a strong base to extend from. In fiscal 2025, the brand grew net sales 17%, reached about 22% household penetration in BellRing’s convenient nutrition category and remained the No. 1 brand in the ready-to-drink segment. BellRing says Premier Protein is sold in more than 20 countries, which helps explain why the company would rather stretch a familiar brand into a new format than build a soda concept from scratch.

The format matters. Protein soda opens the door to drinking occasions where a creamy shake does not naturally fit, including afternoon refreshment or a straight soda replacement. That makes the category feel less like a novelty and more like an attempt to redefine when protein can show up during the day. For BellRing, the question is whether consumers want protein soda as a durable habit or as the latest flavor of functional curiosity.

The timing also reflects pressure inside BellRing’s core business. The company reported second-quarter fiscal 2026 results on May 5, 2026, for the quarter ended March 31, 2026, and said it was updating its outlook amid increased competition, consumer price sensitivity and rising input cost inflation. BellRing has also said it depends on third-party contract manufacturers for most of its products, including one manufacturer that makes nearly half of its RTD protein shakes, a dependence that makes format diversification strategically important.

The company’s broader growth story shows why it is willing to keep innovating around Premier Protein. BellRing says net sales rose from $1.247 billion in 2021 to $2.3166 billion in 2025, and that it has delivered an 18% revenue CAGR since its 2019 IPO. Premier Protein’s lineage also runs deep, with Post having acquired Premier Nutrition in 2013 before BellRing was separated from Post in a corporate transaction completed in 2022.

BellRing’s stock price and capital allocation underline the pressure behind the move. The company’s investor site showed the shares at $16.34 on April 24, 2026, with a market cap of about $1.91 billion, and BellRing repurchased 3.0 million shares for $96.9 million in the first quarter of fiscal 2026. In that setting, Premier Protein soda is more than a flavor experiment. It is BellRing’s bet that protein’s next growth chapter will be written in mainstream beverage formats, not just in the shake fridge.
