Press Release Details

CAMP HILL, Pa., June 1, 2015 (GLOBE NEWSWIRE) -- Harsco Corporation (NYSE:HSC) today announced that it has commenced a cash tender offer (the "Tender Offer") for any and all of its outstanding 2.700% Senior Notes due 2015 (the "Notes").

The Tender Offer is scheduled to expire at 8:30 a.m., New York City time, June 8, 2015, unless extended or earlier terminated (such time, as may be extended, the "Expiration Time"). Holders who validly tender (and do not validly withdraw) their Notes prior to the Expiration Time will be eligible to receive $1,006.25 for each $1,000 principal amount of such tendered Notes, plus any accrued and unpaid interest up to, but not including, the settlement date.

Tendered Notes may be withdrawn at any time at or prior to (i) the Expiration Time or (ii) if the Tender Offer is extended, the 10th business day after the commencement of the Tender Offer. Tendered Notes may also be withdrawn after the 60th business day after commencement of the Tender Offer if for any reason the Tender Offer has not been consummated within 60 business days after commencement of the Tender Offer. Completion of the Tender Offer is subject to certain market and other conditions, including the consummation of the concurrently announced financing transaction. We expect settlement of the Tender Offer to occur promptly after the Expiration Time, which may be the same day as the Expiration Time, unless the Tender Offer is extended or earlier terminated.

The complete terms and conditions of the Tender Offer are described in the Offer to Purchase dated as of June 1, 2015, the related Letter of Transmittal and the Notice of Guaranteed Delivery, copies of which may be obtained from Global Bondholder Services Corporation, the information agent and tender agent and for the Tender Offer, at http://www.gbsc-usa.com/Harsco/, or by telephone at (212) 430-3774 (collect) or at (866) 470-3900 (toll-free).

None of the Company, the trustee, the dealer manager or the information agent and tender agent make any recommendations as to whether holders should tender their Notes pursuant to the Tender Offer, and no one has been authorized by any of them to make such recommendations. Holders must make their own decisions as to whether to tender their Notes, and, if so, the principal amount of Notes to tender.
