Ingram Micro Holding Corp. (INGM) experienced a sharp decline of 5.53% in after-hours trading on Thursday. The drop followed the company's announcement regarding a significant transaction involving its shares.

The movement was triggered by the company's disclosure that its principal stockholder is launching a secondary offering of $200 million worth of common stock. Concurrently, the company announced a stock repurchase program. Market participants typically view large secondary offerings by major insiders as a potential sign of reduced confidence or an increase in share supply, often leading to downward pressure on the stock price in the near term.
