So what is going on here is that he disposed of derivative securities (in this case, options to acquire common stock) and acquired non-derivative securities (LBSR common stock). The difference between 75K derivative securities and the 70K common reflects the cashless exercise price (rather than pay the option strike price, just receive less common stock of commensurate value). So this is a nothing-burger. Just reflecting the change from owning options to owning the stock itself.
