GURU Organic Energy Sets New Amazon Records During October Prime Big Deal Days

Canada Sells 51% More Units in Two Days Than During Last Year’s Four-Day Event
U.S. Units Up 25% for a Third Straight Record, With Zero Sugar Leading in Both Countries

MONTRÉAL, Oct. 20, 2026 (GLOBE NEWSWIRE) — GURU Organic Energy Corp. (TSX: GURU) (“GURU” or the “Company”), Canada’s leading organic energy drink brand¹, today announced record results on Amazon in both Canada and the United States during Amazon’s October Prime Big Deal Days event, held on October 6 and 7, 2026.

In just two days, GURU sold 51% more units on Amazon.ca than during last year’s entire four-day event, making this the Company’s largest Prime Big Deal Days ever in Canada². In the United States, units sold rose 25% over last year’s two-day event, marking GURU’s third consecutive record Prime Big Deal Days on Amazon.com.

A RECORD DAY IN CANADA
October 6 was the best day in GURU’s history on Amazon.ca, for both dollar sales and units sold. The Company sold about 50% more units that day than on its previous best day, and more than twice as many as on the opening day of last year’s event.

Third-party data shows GURU also gained ground in the category. According to Stackline estimates, GURU was the #2 energy drink brand by sales on Amazon.ca during the week of the event and grew its share of category sales compared with the same week last year. Stackline also ranked the GURU Zero Variety Pack as the top-selling energy drink product of any brand on Amazon.ca³.

A THIRD STRAIGHT RECORD IN THE UNITED STATES
On Amazon.com, October 6 was GURU’s second-best sales day ever, behind only the opening day of Amazon’s Prime Day event in June 2026. Over the past two years, GURU’s U.S. unit sales during Prime Big Deal Days have grown nearly 70%.

ZERO SUGAR LEADS THE WAY
GURU’s Zero Sugar line, the focus of the Company’s innovation over the past year, led the event. Zero Sugar products made up nearly half of GURU’s units sold on Amazon.ca and about four in ten on Amazon.com, with the GURU Zero Variety Pack as the Company’s top seller in both countries. In the United States, Zero Sugar accounted for most of the year-over-year unit growth. The three Sorbet-inspired flavors launched since last year’s event (GURU Zero Dragon Fruit Cherry Sorbet, Orange Raspberry Sorbet, and Tropical Sorbet) all added new volume in both markets.

“Prime Big Deal Days is where shoppers vote with their carts, and this year they chose GURU in record numbers. In Canada, we sold more in two days than we did in four last year, and in the U.S. we posted a third straight record. Just as important is where that growth came from: our Zero Sugar line, the focus of our innovation this year, led the way in both countries. We head into the holiday season with real momentum,” commented Tyler Ricks, Executive Chair at GURU.

LOOKING AHEAD
GURU now turns to Black Friday and Cyber Monday on Amazon and on guruenergy.com. Last year, that period delivered record Amazon results for the Company in both markets.
