Insider trading activity at TTM Technologies Inc. (NASDAQ:TTMI) has drawn attention following a significant stock sale by one of its top executives. Catherine A. Gridley, who serves as Executive Vice President and A&D Sector President, sold a substantial block of company shares on June 23, 2026. The transaction involved the disposal of 8,066 shares, generating proceeds of approximately $1.88 million. The shares were sold at varying prices within the range of $201.95 to $213.39 per share.
The sale was not an isolated market decision but rather a structured move executed under a pre-arranged 10b5-1 trading plan. This plan was adopted earlier in the year on February 24, 2026, and was designed specifically to manage tax liabilities arising from the vesting of restricted stock units. Post-transaction, Gridley’s direct holding in TTM Technologies common stock stands at 69,679 shares. This insider activity unfolds against a backdrop of strong market performance for TTMI. The stock is currently trading near its 52-week high of $223.83, reflecting a remarkable 435% return over the past year. Despite this impressive gain, certain analytical perspectives suggest the stock may be trading above its fair value estimate, indicating potential valuation concerns.
