• In connection with certain of our acquisitions, we expect to incur $6.2 million, and may make up to $7.0 million in aggregate earn-out payments between the years 2026 and 2027, of which up to $3.8 million may be paid only in cash, up to $2.8 million may be paid only in common stock and up to $0.4 million may be paid, at our option, in cash or common stock.
