Ste. Michelle Wine Estates acquires A to Z Wineworks

WOODINVILLE, Wash. (September 7, 2022)

Ste. Michelle Wine Estates (“Ste. Michelle”) has acquired A to Z Wineworks (“A to Z”), a top-selling winery in Oregon. This is the first strategic acquisition for Ste. Michelle Wine Estates under the ownership of private equity firm Sycamore Partners.

Together with Ste. Michelle’s Erath Winery, the addition of the A to Z and REX HILL brands gives Ste. Michelle a substantial presence in Oregon and the combined business will be a leading producer of the state’s signature variety, Pinot Noir.

“We are delighted to welcome A to Z to the Ste. Michelle family,” said David Dearie, President and CEO of Ste. Michelle Wine Estates. “Erath and A to Z share the same passion for producing high quality wines at fair prices, making A to Z a natural fit for Ste. Michelle. The future of Pacific Northwest wines – both Oregon and Washington – is bright and we’re excited to introduce new consumers across the country and around the world to the full complement of our region’s outstanding wines.”

Amy Prosenjak, President and CEO of A to Z, will join Ste. Michelle as President of Oregon Brands, overseeing the company’s combined operations in the state.

“I’ve long admired Ste. Michelle’s leadership in the Pacific Northwest and their decades-long commitment to promoting the region’s wines,” said Ms. Prosenjak. “Bill Hatcher, who is retiring as Chairman of the Board for A to Z, gave me the great gift of mentorship over the years. With such deep roots, I look forward to joining David and the Ste. Michelle Senior Leadership Team and together raising the bar even higher for Oregon and the Pacific Northwest.”

In addition to Ms. Prosenjak, A to Z Founding Partners Deb Hatcher, Cheryl Francis, and Sam Tannahill will join Ste. Michelle as consultants. A to Z’s Founding Partners started the company 20 years ago and have worked tirelessly to create the highest quality wine for the greatest sustainable value, a goal that remains the company’s guiding principle.

In addition to developing into one of Oregon’s most iconic wineries, A to Z became a certified B Corp in 2014 in recognition of its positive environmental practices.

“We could not have found a better partner than Ste. Michelle to carry on the legacy of both A to Z and REX HILL,” said Ms. Hatcher. “They understand the Pacific Northwest better than anyone, and they know what it takes to promote an entire region on the global stage.” “Ste. Michelle understands quality and production for both small and large wineries,” said Francis. “We are excited to work with Ste. Michelle to further Oregon’s hard-earned reputation for producing world-class wines.”

Added Tannahill, “Ste. Michelle has always taken a long-term view regarding grape-growing and winemaking, including their commitment to sustainability and their support for viticulture and enology research.”

BNP Paribas Securities Corp. served as financial advisor to A to Z. Bank of the West is continuing as the lender to both Ste. Michelle and A to Z. Kirkland & Ellis acted as legal counsel for Ste. Michelle and Tonkon Torp supported A to Z.

Terms of the transaction were not disclosed.
