4 terms

Rule 144 regulatory

"See the definition of "person" in paragraph (a) of Rule 144."

Rule 144 is a U.S. securities regulation that sets conditions under which restricted or insider-held shares can be legally resold to the public, such as required holding periods, availability of public information, limits on how much can be sold at once, and certain filing requirements. For investors it matters because it determines when previously locked-up shares can enter the market — like a release valve that can increase supply, affect share price, and signal insider intent.

Rule 10b5-1(c) regulatory

"selling plan dated 12/12/2025, that is intended to comply with Rule 10b5-1(c)."

Rule 10b5-1(c) is an SEC guideline that lets company insiders set up a written, pre-planned schedule to buy or sell their company stock when they are not in possession of material, nonpublic information. For investors, it matters because such plans can reduce the appearance of insider trading by separating decisions from inside knowledge—like putting your trades on autopilot—while also requiring scrutiny since pre-planned trades can still affect market confidence and share value.

selling plan financial

"The sales of shares set forth herein are made in connection with a selling plan dated 12/12/2025"

private transaction financial

"Acquired from issuer in private transaction"

A private transaction is the sale or transfer of securities, assets, or ownership stakes carried out directly between a small number of parties rather than on a public exchange. For investors it matters because these deals are less visible and often less liquid than public trades, so pricing can be harder to verify, the investment can be harder to sell quickly, and buyers or sellers may gain strategic advantages not available in open markets — like negotiated terms similar to a private garage sale versus a crowded marketplace.
