TL;DR: Insider/trust sale disclosed: 25,000 shares proposed, prior 10,000-share 10b5-1 sale reported; transaction size is modest versus total outstanding.

The Form 144 reports a proposed sale of 25,000 common shares through Morgan Stanley Smith Barney with an aggregate market value of $288,250 and lists 102,111,652 shares outstanding. The filer states acquisition occurred on 12/31/2014 via a Private Investment Series A from the issuer. A disclosed 10b5-1 sale of 10,000 shares on 05/12/2025 generated $120,000.

Corporate Governance Expert

TL;DR: Disclosure aligns with Rule 144 requirements; includes representation about absence of undisclosed material information and 10b5-1 activity.

The filing includes the standard attestation that the seller is unaware of material adverse nonpublic information and notes a prior 10b5-1 plan sale. It documents acquisition date and payment for the securities and identifies the broker and planned exchange. The disclosure elements are consistent with regulatory expectations for an officer/affiliate or related trust reporting an intended sale, but the form provides no additional governance commentary or rationale for the sale.
