Calix, Inc. (NYSE:CALX) today announced that its board of directors increased the authorization to repurchase the Company's common stock by an additional $100 million under the existing stock repurchase program. The additional authorization announced today will be added to the remaining common stock repurchase authorization which totaled $63.4 million at the end of the first quarter of 2026.

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 Securities and Exchange Commission and other applicable legal requirements. The specific timing, price and size of the purchases will depend on prevailing stock prices, general economic and market conditions, and other considerations consistent with the Company's capital allocation strategy.
