Mechanics Bank Trust Department holds a diversified book of 211 stocks worth $808.2M as of Q2 2026 (disclosed Jul 7, 2026, a ~7-day 13F lag). This quarter Honeywell Aerospace Inc became 13F-reportable for the first time, a listing rather than a purchase; they opened Honeywell International Inc and trimmed Alphabet Inc-CL A. Their largest long position is SS SPDR S&P 500 ETF Trust-US at 5% of the equity book.

Mechanics Bank Trust Department files as a bank or broker: much of this book is custody and client positions, not a proprietary portfolio.
