Tim Wentworth, the CEO of Walgreens Boots Alliance said: "We continue to face a difficult operating environment, including persistent pressures on the US consumer and the impact of recent marketplace dynamics, which have eroded pharmacy margins. "Our results and outlook reflect these headwinds, despite solid performance in both our international and US healthcare segments." Wentworth continued: "Informed by our strategic review, we are focused on improving our core business: retail pharmacy, which is central to the future of healthcare. We are addressing critical issues with urgency and working to unlock opportunities for growth."
