restricted stock units financial

"Includes 30,000 restricted stock units granted under the Issuer's 2020 Equity Incentive Plan which will vest on June 23, 2027."

Restricted stock units are a type of company reward where employees are promised shares of stock, but they only fully own these shares after meeting certain conditions, like staying with the company for a set time. They matter because they can become valuable assets and are often used to motivate employees to help the company succeed.

2020 Equity Incentive Plan financial

"Includes 30,000 restricted stock units granted under the Issuer's 2020 Equity Incentive Plan which will vest on June 23, 2027."

beneficial ownership financial

"The reporting person disclaims beneficial ownership of these securities except to the extent of his pecuniary interest therein"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

pecuniary interest financial

"except to the extent of his pecuniary interest therein, and the inclusion of these shares in this report shall not be deemed an admission"
