10% owner KELLOGG bought 70,000 shares of MERC at $3.38 on 2025-07-22; stock now -78.1% from 52-week high at $1.67.

KELLOGG, a 10% owner of Mercer International, purchased 70,000 shares at $3.38 on 2025-07-22, increasing his holdings to 1,000,000 shares.

This buy activity by a director occurs at a depressed absolute price point relative to recent trading history, though without visibility into her prior trade patterns or stated investment thesis, the motivation for accumulation at this juncture is not transparent. The persistence of unprofitability and the significant discount to prior highs warrant investor attention to whether operational performance stabilizes ahead.
