Item 2: Unregistered Sales of Equity Securities and Use of Proceeds

In January 2023, Teradyne’s Board of Directors cancelled our 2021 repurchase program and approved a new repurchase program for up to $2.0 billion of common stock. During the three months ended March 29, 2026, we repurchased 0.02 million shares of common stock for a total cost of $5.5 million at an average price of $229.00 per share. We record share repurchases at cost, which includes broker commissions and related excise taxes. During the three months ended March 30, 2025, we repurchased 1.5 million shares of common stock for $158.7 million at an average price of $107.21 per share.

The following table includes information with respect to repurchases we made of our common stock during the three months ended March 29, 2026, (in thousands except per share price):

(1)

Includes approximately 175,362 shares at an average price of $245.04 withheld from employees for the payment of taxes.

(2)

As of January 1, 2023, share repurchases net of share issuances are subject to a 1% excise tax under the Inflation Reduction Act. Excise tax incurred is included as part of the cost basis of shares repurchased in the Condensed Consolidated Statements of Convertible Common Shares and Stockholders’ Equity.

We satisfy U.S. federal and state minimum withholding tax obligations due upon the vesting and the conversion of restricted stock units into shares of our common stock, by automatically withholding from the shares being issued, a number of shares with an aggregate fair market value on the date of such vesting and conversion that would satisfy the minimum withholding amount due.
