Janus International Group Announces $75 Million Increase to its Share Repurchase Program

TEMPLE, GA, May 15, 2025 – Janus International Group, Inc. (NYSE: JBI) (“Janus” or the “Company”), a leading provider of access control technologies and building product solutions for the self-storage and other commercial and industrial sectors, today announced its Board of Directors has expanded the Company’s existing share repurchase program, pursuant to which the Company is authorized to purchase up to an additional $75 million of its common stock.

The prior authorization was for $100 million. As of March 29, 2025, the Company has repurchased approximately 7.8 million shares of common stock at a total cost of $83.7 million under the share repurchase program. The repurchase authorization does not have an expiration date and may be terminated by the Company’s Board of Directors at any time.

“The expansion of our share repurchase program reflects the resilience of our business model and the consistency of our cash generation profile,” said Ramey Jackson, Chief Executive Officer. “We remain committed to delivering long-term shareholder value through a balanced and thoughtful approach to capital allocation.” 

The Company may repurchase shares from time to time through open market transactions, block trades, or otherwise, meeting the requirements of Rule 10b-18 under the Securities Exchange Act of 1934, as amended, and in compliance with applicable state and federal securities laws. The timing, as well as the number and value of shares repurchased under the program, will be determined by the Company at its discretion and will depend on a variety of factors, including the Company’s assessment of the intrinsic value of the Company’s common stock, the market price of the Company’s common stock, general market and economic conditions, available liquidity, compliance with the Company’s debt and other agreements, applicable legal requirements, the nature of other investment opportunities available to the Company, and other considerations. The Company is not obligated to purchase any additional shares under the repurchase program, and the program may be suspended, modified, or discontinued at any time without prior notice. No assurance can be given that any particular amount of common stock will be repurchased in the future. The Company expects to fund the repurchases by using cash on hand and expected free cash flow to be generated in the future.
