Johnson Controls announces expiration and final tender results of cash tender offers for senior notes

CORK, Ireland, May 30, 2019 – Johnson Controls International plc (NYSE: JCI) today announced the expiration and the final tender results of its previously announced cash tender offers (each, an “Offer,” and collectively, the “Offers”) to purchase for cash up to $1,500,000,000 aggregate principal amount of certain of its outstanding senior notes (collectively, the “Notes”). The Offers were made pursuant to the terms and conditions set forth in JCI’s Offer to Purchase, dated May 1, 2019, as amended by JCI’s First Supplement to the Offer to Purchase, dated May 15, 2019 (the “First Supplement to the Offer to Purchase” and, as amended, the “Offer to Purchase”).

On May 17, 2019, JCI purchased $1,450,000,000 aggregate principal amount of certain of its Notes that had been tendered and accepted for payment in the Offers. The First Supplement to the Offer to Purchase amended the Offer solely with respect to JCI’s 6.000% notes due 2036 (the “6.000% 2036 Notes”) to provide that the maximum aggregate principal amount of 6.000% 2036 Notes that JCI will accept for purchase in the Offer for such Notes is $50,000,000 (the “6.000% 2036 Notes Series Maximum”) and to extend the withdrawal deadline with respect to the 6.000% 2036 Notes to 11:59 p.m., New

York City time, on May 29, 2019 (the “6.000% 2036 Notes Withdrawal Deadline”). The terms of the Offers provide that Notes tendered at or prior to 5:00 p.m., New York City time, on May 14, 2019 (the “Early Tender Deadline”) have priority over any Notes tendered after the Early Tender Deadline (including any 6.000% Notes withdrawn after the Early Tender Deadline and thereafterre-tendered at or prior to 11:59 p.m., New York City time, on May 29, 2019 (the “Expiration Date”)).

As of the Expiration Date, according to information received from D.F. King & Co., Inc., the Tender Agent and Information Agent for the Offers, $211,236,000 aggregate principal amount of 6.000% 2036 Notes had been validly tendered and not validly withdrawn on or prior to the 6.000% 2036 Notes Withdrawal Deadline, which amount is greater than the 6.000% 2036 Notes Series Maximum. No 6.000% 2036 Notes were tendered after the Early Tender Deadline. As a result, JCI expects to accept for purchase $50,000,000 aggregate principal amount of 6.000% 2036 Notes using a proration factor of approximately 23.67% and none of JCI’s 4.950% notes due 2064 or other Notes will be purchased in the Offers. Notes not accepted for purchase will be promptly credited to the account of the registered holder of such Notes with The Depository Trust Company in accordance with the Offer to Purchase.

Holders of 6.000% 2036 Notes accepted for purchase will receive total consideration of $1,191.91 per $1,000 in aggregate principal amount of 6.000% 2036 Notes (which represents the Total Consideration (as defined in the Offer to Purchase) for such series and includes an early tender premium of $30 per $1,000 in aggregate principal amount of Notes accepted for purchase) plus accrued and unpaid interest, if any, from the last interest payment date for the 6.000% 2036 Notes up to, but not including, the settlement date for the 6.000% 2036 Notes accepted in the Offers, which is expected to be May 31, 2019.

JCI’s obligation to accept for purchase, and to pay for, Notes that are validly tendered and not validly withdrawn pursuant to each Offer is conditioned on the satisfaction or waiver by JCI of a number of conditions as described in the Offer to Purchase. No Offer is conditioned on the consummation of the other Offers, or on the receipt of financing.
