Penobscot Investment Management Company, Inc. holds a diversified book of 315 reported positions worth $1.5B as of Q2 2026 (disclosed Jul 24, 2026, a ~24-day 13F lag). This quarter Honeywell Aerospace Inc first appears in 13F filings, a listing rather than a purchase; they opened Vertiv Holdings Co-A and trimmed Apple Inc. Their largest long position is Apple Inc at 6% of the reported non-option book. Cloning the disclosed picks since 2024 would be +22% (+11.6%/yr). That is a simulation of the disclosed long book, not audited returns.
Growth of $10,000 cloning Penobscot Investment Management Company, Inc.'s disclosed long 13F book, rebalanced on each filing date (so it reflects each quarter's actual reporting lag, ~24 days for the latest filing, with no look-ahead), total-return basis (dividends reinvested), derived from end-of-day prices. “Their reported book” values the same picks from quarter-end, before they were public. S&P 500 is SPY total return over the same window. Excludes shorts, cash, options and non-13F holdings. Not investment advice.
