Insights

Equity Capital Markets Analyst

Form 144 notice lists proposed resale of common stock via Merrill Lynch on NASDAQ.

The filing is a regulatory notice of an intended sale method rather than a completed transaction. It names Merrill Lynch and shows an entry of 2,500 alongside exchange identification NASDAQ and filing date 05/11/2026.

Because the document records historical stock plan issuances dated in 2021–2022, subsequent SEC filings or broker confirmations would be needed to confirm execution or proceeds; the form itself does not state that sales occurred.

Corporate Governance Specialist

This is an administrative resale notice referencing prior stock plan activity.

The entries labeled Stock Plan Activity list small issuance counts by date; these illustrate source dates for the shares but do not change ownership details within this excerpt.

Regulatory timing and any volume limits under Rule 144 are not shown here; confirm lockup, holding periods, or broker execution details in related filings if needed.

Rule 144 regulatory

"notice of proposed sale under Rule 144 (Form 144 context)"

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.
