Insights

Corporate Governance Analyst

Multiple pre-arranged sales recorded under a trading plan; vesting and sales are administrative compensation and liquidity events.

The filing lists RSU vesting on 05/22/2026 and numerous 10b5-1 sales by Jeremy Chadwick dated from 03/02/2026 to 04/22/2026. The presence of a 10b5-1 plan implies transactions executed under a pre-established plan; the excerpt labels several entries explicitly as 10b5-1 Sales.

Cash treatment and whether sales were part of the Form 144 registration or prior dispositions are not detailed in the excerpt; subsequent filings or confirmations would clarify proceeds recipient and any remaining holdings.

Sale volumes vary widely; a few large dispositions (e.g., 91,250 shares) dominate the reported activity.

The excerpt provides per-trade share counts and gross proceeds for many entries, for example 91,250 shares for $7,063,733.26 on 03/23/2026, and smaller trades such as 300 shares on 04/22/2026. These figures form the transaction record visible in this filing.

Post-transaction holdings and whether any sales were for tax withholding related to RSU vesting are not specified in the provided excerpt; further disclosure would show remaining insider position and tax treatments.

10b5-1 regulatory

"Entries labeled "10b5-1 Sales" for Jeremy Chadwick"

A 10b5-1 plan is a pre-set schedule that lets company insiders buy or sell shares according to written instructions made when they do not possess material, nonpublic information. Think of it as a timed automatic payment for stock trades: it helps insiders avoid accusations of trading on secret information and gives outside investors a clearer signal about whether sales are routine or potentially informative about the company’s prospects.

Restricted Stock Units financial

"Shares acquired upon vesting of Restricted Stock Units awarded under the Issuer's 2020 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.

Form 144 regulatory

"Filer Information | Securities To Be Sold | Securities Sold During The Past 3 Months"

Form 144 is a document that investors must file with the government when they plan to sell a large number of shares of a company's stock. It helps ensure transparency so everyone knows how many shares are being sold and when, which can impact the stock's price.
