ST. LOUIS – (BUSINESS WIRE) – Belden Inc. (NYSE: BDC) today announced that it has commenced a cash tender offer to purchase any and all of its outstanding 5.5% senior subordinated notes due 2022 (the “2022 Notes”). As of June 27, 2017, there was $700 million aggregate principal amount of the 2022 Notes outstanding. The tender offer is being made pursuant to an offer to purchase, dated today, and a related letter of transmittal and notice of guaranteed delivery. The tender offer will expire at 5:00 p.m., New York City Time, on July 5, 2017, unless extended or earlier terminated (the “Expiration Time”). Tendered 2022 Notes may be withdrawn at any time before the Expiration Time.

Holders that validly tender their 2022 Notes prior to the Expiration Time, or who deliver to the information agent a properly completed and duly executed notice of guaranteed delivery and subsequently deliver such 2022 Notes, each in accordance with the instructions described in the offer to purchase, will receive total cash consideration of $1,033.00 per $1,000 principal amount of 2022 Notes, plus any accrued and unpaid interest to, but not including, the settlement date, which is expected to be July 6, 2017, subject to satisfaction of the conditions to the tender offer.

The tender offer is conditioned upon, among other things, Belden’s successful completion of a proposed issuance (the “Notes Offering”) of debt securities in an aggregate principal amount of at least €400 million (equivalent to approximately $448 million as of June 26, 2017) on terms satisfactory to Belden. The tender offer is not conditioned on any minimum amount of 2022 Notes being tendered. Subject to applicable law, Belden may amend, extend or terminate the tender offer, and may waive conditions to the offer, in each case in its sole discretion. Belden currently intends to redeem or otherwise repurchase any 2022 Notes outstanding following the consummation of the tender offer that are not purchased pursuant to the tender offer; however, Belden has not determined the timing of any such redemption or repurchases and is under no obligation to redeem or repurchase any such 2022 Notes, and Belden expressly reserves the right to elect not to redeem or repurchase any such 2022 Notes for any reason, including general market conditions or other uses for its cash resources.
