Lululemon has appointed CFO Meghan Frank and Chief Commercial Officer André Maestrini as co-CEOs while it searches for a full-time replacement for former CEO Calvin McDonald. This leadership shift comes as the company grapples with significant financial challenges, including a 50% decline in stock price and a projected 22.8% drop in earnings per share. Although the last reported quarter saw a 7% increase in revenue, Lululemon is facing headwinds from weak U.S. traffic trends and a 2% year-over-year decline in Americas revenues.
