Calix CALX Share Repurchase Program - Amount Remaining

We maintain a common stock repurchase program. Under the repurchase program, repurchases can be made from time to time using a variety of methods, which may include open market purchases, privately negotiated transactions or otherwise, all in accordance with the rules of the SEC and other applicable legal requirements. The specific timing, price and size of the purchases depends on prevailing stock prices, general economic and market conditions and other considerations consistent with our capital allocation strategy. The repurchase program does not obligate us to acquire a particular amount of common stock, and the repurchase program may be suspended or discontinued at any time at our discretion. During 2026, our Board of Directors authorized a $225.0 million increase to this program. During the three months ended June 27, 2026, we purchased 1.6 million shares of common stock for an aggregate purchase price of $69.4 million at an average price per share of $42.48. During the six months ended June 27, 2026, we purchased 5.0 million shares of common stock for an aggregate purchase price of $240.2 million at an average price per share of $48.42. As of June 27, 2026, the remaining authorized balance under this program was $94.1 million.
