Corporate Governance Specialist

TL;DR: The filer affirms no undisclosed material non-public information and follows Rule 144 mechanics.

The filing documents the acquisition date (05/31/2019) and the nature of acquisition (stock conversion before IPO), which supports Rule 144 compliance timing for affiliates selling restricted shares. The certification that no material adverse information is undisclosed is a required attestation for these notices.

Investors should watch for any SEC Form 4 filings or company disclosures clarifying whether sales are part of an organized program; absent such disclosures, this remains a notification of intent rather than confirmation of execution.
