On October 28, 2021, we announced that our Board of Directors authorized a $70 million share repurchase program. This share repurchase program was effective as of November 2, 2021, and has no expiration date. On October 25, 2022, our Board of Directors authorized an additional $70 million under the share repurchase program. The timing of share repurchases and the number of shares of common stock to be repurchased will depend upon prevailing market conditions and other factors. Repurchases under this program will be made using our existing cash resources and may be commenced or suspended from time to time at our discretion without prior notice. Repurchases may be made in the open market, through 10b5-1 programs, or in privately negotiated transactions at prevailing market rates in accordance with federal securities laws. All such repurchased shares and related costs are held as treasury stock and accounted for at trade date using the cost method. We did not repurchase any shares of our common stock during the three and nine months ended September 26, 2026.
