Restricted stock units ("RSUs") financial

"Restricted stock units ("RSUs") vest in three equal installments on the first, second and third anniversaries..."

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.

1-for-10 reverse split financial

"Effective at 12:01 AM on July 1, 2026, the Issuer effected a 1-for-10 reverse split of the Issuer's common stock..."

equity awards financial

"In addition, proportionate adjustments were made to the Issuer's outstanding equity awards."

Equity awards are payments to employees or directors made in the form of company stock or rights to buy stock later, serving as a way to share ownership rather than cash. For investors, they matter because they align staff incentives with company performance, can increase the number of shares outstanding over time (which can reduce each share’s claim on profits), and create compensation costs that affect reported earnings.
