Securities Analyst

TL;DR: The filing shows a derivative option related to 8,773 underlying shares and an exercise price of $26.56 was cancelled; numbers reflect a reverse split.

The Form lists specific option parameters including exercisable and expiration dates and quantifies the underlying common stock. It also notes adjusted amounts resulting from the 1-for-20 reverse split. The reporting person did not receive consideration for the cancellation, per the explanatory footnote. For analysts, this provides a factual record of a contractual equity change but contains no additional financial terms or transfers to quantify immediate economic impact.
