It's neither odd nor surprising that the 78-year-old founder of a company would sell shares periodically. Even as a fellow stockholder down 70%, I don't begrudge Dr. Taylor his right to sell.
On the other hand, if he's on a glide path to retirement, why are we paying him over $600K per year when Mr. Dunleavy (CEO of this small, unprofitable firm) also receives almost $600K? Viewed through a financial analyst's lens, the firm looks too much like a piggy bank for its execs.
OPTT's sales in the past year are about $6 million, and the salaries for those two alone soak up almost 20% of sales. We shareholders are paying Messrs Taylor and Dunleavy (together) over $0.11 per share in annual salary. Ouch.
They have never sold one single fudging PowerPhooey! The only income they ever get is from "pre-feasibility" studies gummint handouts and of course the lovely IPO's. Must be time to print some more shares!
