Madison Small Cap Fund stated the following regarding Primo Brands Corporation (NYSE:PRMB) in its fourth quarter 2025 investor letter:
“On the other hand, longtime portfolio holding Primo Brands Corporation (NYSE:PRMB), saw its stock price cut in half. We acquired PRMB back in 2020. We like the water delivery business, we believe it exhibits all the traits we look for in a quality business. PRMB is one of the largest, if not the largest direct water delivery companies in North America, serving 5 gallon bottled water to consumers and small businesses via a modest monthly subscription or direct exchange. They also own some very attractive consumer retail brands like Mountain Valley and Saratoga Springs. In 2022 PRMB was acquired by Blue Triton Holdings which was the rebranded Nestle Water business and privately held. Blue Triton acquired Primo via a reverse merger, allowing it to go public. The combination created North America’s largest water delivery and consumer retail franchise and potentially $200 million in cost savings, along with noncore asset sales that would clean up the balance sheet. The company delivered on expanding margins with steady topline growth and the market rewarded the company with a much higher valuation, making this one of our better performing stocks in 2023 and 2024. In 2025, the company decided to accelerate the integration and pull forward the cost savings. This proved to be a poor decision and during the summer of 2025 the company faced several logistical challenges with late or missed deliveries and subscription cancellations. This was exacerbated by a tornado that damaged one of their critical bottling plants in Texas. Although unfortunate, the mistakes were nowhere near fatal and new management has been quick to right the ship. However, the stock has been vaporized, erasing two years’ worth of gains.
We believe the business is on track to deliver on all its opportunities from the combination and the current stock price represents an excellent investment opportunity.”
