Insights

Equity Capital Markets Analyst

Form 144 lists resale activity by trusts under brokered plans.

The table shows multiple 10b5-1 program sales executed or scheduled through Morgan Stanley Smith Barney LLC, with rows for 05/07/2026 and 05/19/2026

Cash proceeds per trade are included in the rows; the filing is procedural notice of resale rather than issuer dilution. Subsequent filings may report further sales or confirmations.

Compliance Attorney

The filing documents Rule 144 resale mechanics by affiliated trusts.

The entries identify trusts (e.g., NAVAD TRUST, N2021 IRREVOCABLE TRUST) using 10b5-1 plans to sell shares and provide trade dates, share counts, and gross proceeds per line.

This is a disclosure step required for certain resale exemptions; it does not indicate issuer action or change to capital structure.

Form 144 regulatory

"Filer Information | 144: Filer Information"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.

10b5-1 regulatory

"10b5-1 Sales for N2021 IRREVOCABLE TRUST"

A 10b5-1 plan is a pre-set schedule that lets company insiders buy or sell shares according to written instructions made when they do not possess material, nonpublic information. Think of it as a timed automatic payment for stock trades: it helps insiders avoid accusations of trading on secret information and gives outside investors a clearer signal about whether sales are routine or potentially informative about the company’s prospects.

Irrevocable Trust U/A DTD other

"N2021 IRREVOCABLE TRUST U/A DTD06/10/2021"

Broker-dealer market

"Morgan Stanley Smith Barney LLC Executive Financial Services"

A broker-dealer is a licensed firm or individual that both executes trades on behalf of clients (acting as a broker) and buys or sells securities for its own account (acting as a dealer). Investors care because broker-dealers provide the plumbing of markets — they place orders, hold or move cash and securities, offer research or advice, and their stability and fees directly affect trade execution, costs, and the safety of client funds; think of them as a combined travel agent and taxi for your investments.
