"The Reporting Person was granted 6,250 restricted stock units ("RSUs") pursuant to the Issuer's 2021 Equity Incentive Plan"
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.

"The Reporting Person disclaims beneficial ownership of the common stock owned directly by Alma Life Sciences, LLC, except to the extent of her pecuniary interest therein"
stock option financial
"The stock option will vest in substantially equal monthly installments over the 12 months following the date of grant"
A stock option is a contract that gives you the right to buy or sell a company's stock at a specific price within a certain time frame. People use them to potentially make money if the stock's price moves favorably or to protect against losses. It's like holding a coupon that can be used to buy or sell stock at a set price later on.
vesting financial
"any remaining unvested portion of the stock option will vest on the date of such 2027 Annual Meeting"
Vesting is the process by which you earn full ownership of something, like company stock or a retirement benefit, over time. It’s like earning the right to keep a gift piece by piece the longer you stay with a company, making sure employees stay committed before they receive all the benefits.
