Compliance / Securities Counsel

Form 144 confirms compliance steps for a public sale under Rule 144 but does not itself effect a sale.

The document records acquisition details: a stock conversion before IPO on 12/31/2020 and indicates payment was wired to portfolio company. It also contains the required seller representation about absence of undisclosed material adverse information and the caution about criminal penalties for misstatements.

Stakeholders should watch for subsequent Form 4 or 5 filings that report completed sales or any amendments that change the aggregate amount or disclose a trading plan adoption date.
