Curaleaf celebrates six years of its national at-register donation program for Breast Cancer Action Month

All contributions benefit The Carol M. Baldwin Breast Cancer Research Fund of CNY, also known as The Baldwin Fun

STAMFORD, Conn.Oct. 1, 2025  — Curaleaf Holdings, Inc. (TSX: CURA) (OTCQX: CURLF) (“Curaleaf” or the “Company”), a leading international provider of consumer cannabis products, is proud to announce its continued Breast Cancer Action Month (BCAM) initiative, this year in partnership with Carol M. Baldwin Breast Cancer Research Fund of CNY, also known as The Baldwin Fund. Throughout October, Curaleaf customers at the majority of the company’s retail locations are invited to “Round Up for Research” at checkout, with proceeds supporting lifesaving breast cancer research at Upstate Medical University in Syracuse, New York.

This year’s partnership will allow Curaleaf to scale its impact nationwide, uniting customers and communities around a shared goal of funding breakthrough research and honoring those who have faced breast cancer. For more than 20 years, The Baldwin Fund has raised over $13 million to advance breast cancer research and patient care, building on founder Carol M. Baldwin’s mantra: “Together We Will Find a Cure.” Today, the Fund is embarking on a bold $50 million campaign to help the Upstate Cancer Center achieve National Cancer Institute (NCI) designation, the gold standard for innovative cancer programs.

“My mother’s mission was simple but powerful—’Together We Will Find a Cure,'” said Stephen Baldwin on behalf of The Baldwin Fund. “This partnership with Curaleaf not only carries her legacy forward but also gives people across the country an easy and meaningful way to join us in the fight against breast cancer. I’ve been a patron of Curaleaf since the day they opened, and I truly believe it’s the most trustworthy brand and product in the industry, with a deep commitment to quality and community. By rounding up at the register, every customer can play a role in honoring survivors, supporting families, and funding the research that will one day end this disease.”

“At Curaleaf, Breast Cancer Action Month is a moment we have recognized on a national scale since 2020, and for us it’s an opportunity to stand with our communities, customers and patients in a meaningful way,” said Boris Jordan, Curaleaf Chairman and CEO. “During the month of October, we pause to recognize those who have been diagnosed, are currently facing a diagnosis, or have passed as a result of breast cancer. By partnering with The Baldwin Fund, we’re inviting our customers to join us in honoring their strength, supporting their families, and funding the research that will one day bring us closer to a cure.”

While cannabis is not a treatment for cancer, some people living with breast cancer report that cannabis products can help them manage pain, nausea, anxiety, insomnia, and other side effects of treatment. Curaleaf is committed to providing safe, high-quality cannabis options for patients and consumers navigating their health journeys, while continuing to advocate for more research into cannabis and cancer care.

The majority of Curaleaf dispensaries across the Company’s retail footprint will participate in this program, as permitted within state regulations. The 13 participating states include, ArizonaConnecticutFloridaIllinoisMaineMarylandMassachusettsNevadaNew JerseyNew YorkNorth DakotaPennsylvania and Utah.
