Rule 10b5-1 plan financial
"Transaction effected pursuant to a Rule 10b5-1 plan adopted by the Reporting Person on November 5, 2025."
A Rule 10b5-1 plan is a prearranged, written schedule that lets corporate insiders buy or sell company stock at set times or amounts, even if they later learn material nonpublic information. Think of it like setting an automatic thermostat for trades: it creates a clear record that trades were planned in advance, reducing the risk of insider-trading accusations and helping investors trust that insider transactions are routine rather than based on secret information.
RSUs financial
"Includes (i) 72,375 unvested RSUs of the 289,500 RSUs granted to the Reporting Person on January 11, 2023..."
RSUs, or restricted stock units, are a form of company shares given to employees as part of their compensation. They are typically awarded with certain restrictions, such as a waiting period before they can be fully owned or sold, similar to earning a gift that becomes fully yours over time. For investors, RSUs can impact a company's stock offerings and reflect how much the company relies on stock-based incentives to attract and retain talent.
volume weighted average price financial
"Price is the volume weighted average price of all transactions made by the Reporting Person on the transaction date..."
The volume weighted average price (VWAP) is a way to measure the average price of a security, such as a stock, over a specific period, taking into account how many units were traded at each price. It’s similar to calculating the average cost of items bought when some are more frequently purchased than others. Investors use VWAP to assess whether a security is being bought or sold at a fair price during trading.
Employee Stock Purchase Plan financial
"The 10,696 shares that the Reporting Person previously acquired under the Liquidia Corporation 2020 Employee Stock Purchase Plan ("ESPP") have been rescinded..."
An employee stock purchase plan is a company program that lets workers buy shares through small payroll deductions, often at a discount to the market price and after a set offering period. Think of it like a workplace savings plan that turns into ownership: it encourages employees to share in the company’s success and can create predictable buying or selling of stock that investors watch because it affects supply, demand and employee incentives.
