Rhea-AI Filing Summary

Twilio Inc. Chief Financial Officer Aidan Viggiano reported selling a total of 9,093 shares of Twilio Class A Common Stock on June 30, 2026 in a series of open-market transactions.

Following these transactions, Viggiano continues to hold a direct position of more than 100,000 Twilio Class A shares.

Tax-related sales Portion of 9,093 shares Shares sold to cover statutory tax withholding on RSU vesting
Restricted Stock Units ("RSUs") financial
"Represents the number of shares sold to cover the statutory tax withholding obligations in connection with the vesting of Restricted Stock Units ("RSUs")."
Restricted stock units (RSUs) are a company promise to give an employee shares of stock (or cash equivalent) in the future, but only after certain conditions—usually staying with the company for a set time or hitting performance goals—are met. Investors watch RSUs because when they vest they increase the number of shares outstanding and can lead insiders to sell shares, affecting share price, company dilution and the true cost of employee pay.
sell-to-cover financial
"require the satisfaction of minimum statutory tax withholding obligations to be funded by a "sell-to-cover" transaction"
Sell-to-cover is when part of newly issued or exercised company stock is immediately sold to pay required taxes and fees, so the recipient keeps the remaining shares. For investors this matters because it reduces the number of shares insiders or employees actually hold after a grant, can create small, routine share sales that aren’t signal of cashing out, and slightly increases share supply on the market—like selling a portion of a paycheck to cover the tax bill.
weighted average price financial
"The reported price in Column 4 is a weighted average price."
Weighted average price is the average price of a security where each trade or component is counted according to its size, so bigger trades pull the average more than smaller ones. Think of it like calculating the average cost of a grocery haul where items you bought more of have greater influence on the final per-item cost. Investors use it to understand the true average price paid or received, judge execution quality, and compare trading performance against market movement.
statutory tax withholding obligations financial
"sold to cover the statutory tax withholding obligations in connection with the vesting of Restricted Stock Units"
Class A Common Stock financial
"security_title": "Class A Common Stock""
Class A common stock is a category of a company’s shares that carries a specific set of ownership rights—most commonly defined voting power and claims on dividends—set out in the company’s charter. For investors it matters because the class determines how much influence you have over corporate decisions, the share’s likely dividend and trading behavior, and how it compares in value to other share classes, like choosing a particular seat with different privileges at the company’s decision-making table.
