restricted stock unit financial
"upon vesting and settlement of a restricted stock unit (RSU) granted under the 2023 Plan"
A restricted stock unit is a promise from a company to give an employee shares of stock after certain conditions are met, like staying with the company for a set amount of time. It’s like earning a bonus that turns into company stock once you’ve proven your commitment, making it a way to motivate and reward employees.
2023 Stock Option and Incentive Plan financial
"RSU granted under the Issuer's 2023 Stock Option and Incentive Plan (the 2023 Plan)"
weighted-average price financial
"The price reported in Column 4 is a weighted-average price."
Weighted-average price is the average of multiple prices where each price is counted according to its size or importance—larger trades carry more weight than smaller ones, like averaging course grades by credit hours. It matters to investors because it gives a more realistic picture of the true price paid or received, helping assess trade execution, compare performance, calculate cost basis, and value positions more accurately than a simple average.
pecuniary interest financial
"disclaims beneficial ownership of these securities except to the extent of his pecuniary interest"
Irrevocable Trust financial
"Shares held by The Ram Aiyar Irrevocable Trust, for which the Reporting Person serves as trustee."
An irrevocable trust is a legal arrangement where an owner transfers assets into a separate entity managed by a trustee and gives up the power to modify or reclaim those assets. For investors it matters because putting stock or other holdings into such a trust can change who controls and benefits from the assets, affect taxes and creditor protection, and influence how easy it is to sell or value those holdings—like placing valuables in a locked safe overseen by someone else.
