AMASS Brands Group (NASDAQ:AMSS) ("AMASS" or "the Company"), a premium, multi-category beverage platform spanning non-alcohol, functional, and alcohol 2.0 products, today announced the launch of two limited edition flavors within its AMASS Electrolyte Mixers ready-to-drink ("RTD") line: Tonic and Transfusion. The limited edition launch builds on strong early commercial traction for the AMASS Electrolyte Mixers line. In the first full month following its May 2026 debut, the line generated approximately $36,000 in gross revenue across the Company's direct-to-consumer and wholesale channels, representing approximately $429,000 in annualized gross revenue1, supported by the brand's initial distribution partnership in the Midwest.

AMASS Tonic delivers 82% less sugar than the leading tonic water mixer and AMASS Transfusion has 66% less sugar than its leading competitor. The new, non-alcoholic flavors are formulated with essential electrolytes and real Pacific sea salt. Each serving contains 250mg of sodium, 60mg of potassium, and 20mg of magnesium. Both flavors contain no artificial sweeteners, colors, or flavors, and are Non-GMO, Vegan, and Gluten-Free. The drinks are designed for dual use as a standalone beverage or mixer with alcoholic or non-alcoholic spirits, and are initially available through the Company’s direct-to-consumer channel at www.amass.com.

Amass Tonic delivers the crisp, bittersweet profile of a classic tonic water, built for the premium mixer occasion. The Tonic launch enters the largest tonic water market in the world. North America accounted for 39.4% of global tonic water value in 2024, approximately $0.6 billion, driven by cocktail culture and sustained demand for premium mixers.2 The U.S. and Canada tonic water market is projected to grow from $399 million in 2025 to $655 million by 2032, a 7.3% compound annual growth rate.3

Amass Transfusion pairs grape and ginger in a flavor profile inspired by the iconic golf course cocktail widely known as "Golf’s Greatest Drink." The Transfusion launch arrives amid a record golf boom in the United States. According to the National Golf Foundation, 47.2 million Americans played golf in 2024, up 5% year-over-year and 38% versus pre-pandemic 2019, with rounds played reaching a record 545 million.4 The Transfusion, the grape and ginger cocktail that has become golf’s signature drink, is now crossing from course beverage carts into mainstream bars and at-home occasions, supported by growing social media attention.5
