Rule 10b5-1 trading plan regulatory

"These shares were sold pursuant to a plan adopted by the Reporting Person on or around March 13, 2026."

A Rule 10b5-1 trading plan is a pre-arranged schedule that allows company insiders to buy or sell stock at specific times, even if they have inside information. It helps prevent accusations of unfair trading by making these transactions look planned and transparent, rather than sneaky or illegal.

restricted stock units ("RSUs") financial

"arising in connection with the vesting on August 10, 2026 of the time-based restricted stock units ("RSUs") previously granted"

Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.

2025 Omnibus Plan financial

"previously granted to the Reporting Person on February 20, 2026 pursuant to the Issuer's 2025 Omnibus Plan."

tax withholding obligations financial

"withheld by the Issuer to satisfy the minimum tax withholding obligations of the Reporting Person arising in connection with the vesting"
