Janus International Group, Inc. Announces Redemption of Warrants

TEMPLE, GA, October 13, 2021 – Janus International Group, Inc. (NYSE: JBI) (“Janus” or the “Company”) today announced that the Company will redeem all of its outstanding warrants (the “Warrants”) to purchase shares of the Company’s common stock, par value $0.0001 per share (the “Common Stock”), that were issued under the Warrant Agreement, dated as of June 7, 2021 by and between the Company (f/k/a Juniper Industrial Holdings, Inc.) and Continental Stock Transfer & Trust Company (the “Warrant Agent”) and the Warrant Agreement, dated as of July 15, 2021, by and between the Company and the Warrant Agent (together, the “Warrant Agreements”), for a redemption price of $0.10 per Warrant (the “Redemption Price”), that remain outstanding at 5:00 p.m. New York City time on November 12, 2021 (the “Redemption Date”).

Under the terms of the Warrant Agreements, the Company is entitled to redeem all of the outstanding Warrants if the last sales price of the Common Stock has been at least $10.00 per share on the trading day prior to the date on which a notice of redemption is given. This share price performance target has been met. At the direction of the Company, the Warrant Agent has delivered a notice of redemption to each of the registered holders of the outstanding Warrants.

In accordance with the Warrant Agreements, upon delivery of the notice of redemption, the Warrants may be exercised either for cash or on a “cashless basis.” Accordingly, holders may continue to exercise Warrants and receive Common Stock in exchange for payment in cash of the $11.50 per warrant exercise price. Alternatively, a holder may surrender Warrants for a certain number of a share of Common Stock (such fraction determined by reference to the Warrant Agreements and described in the notice of redemption) that such holder would have been entitled to receive upon a cash exercise of a Warrant. Holders of warrants that elect a “make-whole” cashless exercise of the Warrants will receive 0.3 of a share of Common Stock for each Warrant surrendered for exercise. The exercise procedures are described in the notice of redemption and the election to purchase included therein. Any Warrants that remain unexercised at 5:00 p.m. New York City time on the Redemption Date will be delisted, void and no longer exercisable, and the holders will have no rights with respect to those Warrants, except to receive the Redemption Price.

The number of shares of Common Stock that each exercising warrant holder will receive by virtue of the make-whole cashless exercise (instead of paying the $11.50 per Warrant cash exercise price) was calculated in accordance with the terms of the Warrant Agreements with reference to the table set forth in Section 6.2 of the Warrant Agreements based on the fair market value of the shares of Common Stock and length of time to the applicable expiration of the Warrants. If any holder of Warrants would, after taking into account all of such holder’s Warrants exercised at one time, be entitled to receive a fractional interest in a share of Common Stock, the number of shares the holder will be entitled to receive will be rounded down to the nearest whole number of shares.

Janus understands from the New York Stock Exchange that November 11, 2021, the trading day prior to the Redemption Date, will be the last day on which the Warrants will be traded on the New York Stock Exchange.

None of Janus, its board of directors or employees has made or is making any representation or recommendation to any holder of the Warrants as to whether to exercise, whether on a cash or cashless basis, or refrain from exercising any Warrants.

Issuance of the shares of Common Stock underlying the Warrants has been registered by Janus under the Securities Act of 1933, as amended, and is covered by a registration statement filed on Form S-1 with, and declared effective by, the Securities and Exchange Commission (Registration No. 333-257731). Exercise of Warrants held in “street name” should be directed through the broker of the warrant holder. In addition to the broker, questions may also be directed to Continental Stock Transfer & Trust Company, 1 State Street, 30th Floor, New York, New York 10004, Attention: Compliance Department, Telephone Number (212) 509-4000 or to Morrow Sodali at (800) 662-5200 (for individuals) / (203) 658-9400 (for banks and brokerages) or by email at JBI@info.morrowsodali.com.
