• Option exercise (code M): 50,000 shares acquired at $1.17 → total cost $58,500.

Context

• The filing shows both option exercise(s) and an immediate open-market sale; the Form does not state whether the sale covered exercise costs or tax withholding.
• Exercises convert derivative instruments (options) into common stock; the $0 disposition line reflects the conversion/termination of the derivative interest.
• The sale under a 10b5-1 plan indicates it was preplanned and thus may be routine rather than an ad hoc decision.
