New insider activity at Birkenstock Holding plc ( (BIRK) ) has taken place on June 9, 2026.

President EMEA Mehdi Nico Bouyakhf has executed a major stock sale in Birkenstock Holding plc, offloading 90,000 shares in a single transaction. The sale, valued at $3,829,200, highlights a significant move by the senior executive and represents a notable insider transaction in the company’s stock.

Birkenstock shares jumped about 17% to around $38.90 after the company announced a $250M accelerated share repurchase with Goldman Sachs, framed as exploiting a disconnect between its strong fundamentals and the stock price. Goldman Sachs modestly lifted its valuation model to reflect the buyback, which management presents as the best current capital use amid confidence in 13–15% annual revenue growth and solid cash generation, while Telsey trimmed its valuation assumptions after slightly soft Q2 results despite ongoing strong demand and expansion opportunities.
