Investors haven’t been too hopeful lately: Neuronetics has lost 90 percent of its initial stock value, dropping from around $25 to $2.50 a share. That didn’t stop the board from paying Thacher $3.3 million in stock and cash last year. Neuronetics announced Thacher’s departure in February, but it has agreed to continue his $535,000 base salary, plus benefits, this year.
