Rule 144 notice lists proposed resale quantities and broker details.

The notice documents proposed sales of 210,066 shares via an Exercise of Stock Options on 05/26/2026, and previously vested equity awards: 28,229 RSUs (grant 02/06/2025) and 80,153 PSUs (grant 02/08/2025).

Because Rule 144 filings notify of intended resales under a public‑sale exemption, actual execution, proceeds, and timing depend on holder decisions and market arrangements; subsequent SEC filings may show completed transactions.

Rule 144 regulatory

"Securities To Be Sold; Exercise of Stock Options on 05/26/2026"

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.

RSU financial

"Restricted Stock Units | 02/06/2025 | Issuer | 28,229"

Restricted stock units (RSUs) are a form of company shares given to employees as part of their compensation, usually with certain restrictions or conditions, such as remaining with the company for a set period. When these restrictions lift, employees receive actual shares that they can sell or hold. For investors, RSUs can impact a company's stock supply and reflect the company's commitment to attracting and retaining talent.

PSU financial

"Performance Stock Units | 02/08/2025 | Issuer | 80,153"

A PSU is a company where the government owns a controlling stake and often plays a direct role in its management and strategy. Think of it like a business that operates with public oversight, similar to a town-run utility versus a private neighborhood service. Investors watch PSUs differently because government involvement can affect profits, dividend policies, regulatory treatment and stability, so these stocks may behave more like policy instruments than pure market-driven enterprises.
