PHI, INC. ANNOUNCES FINAL RESULTS OF TENDER OFFER AND CONSENT SOLICITATION FOR ITS 8.625% SENIOR NOTES DUE 2018

LAFAYETTE, LA—March 31, 2014 — PHI, Inc. (“PHI”) (The Nasdaq Global Market: PHII (voting) and PHIIK (non-voting)) announced today the final results of the previously-announced tender offer and consent solicitation (the “Tender Offer”) for all of its outstanding 8.625% Senior Notes due 2018 (the “2018 Notes”). The Tender Offer expired at 12:00 midnight, New York City time, at the end of March 28, 2014 (the “Expiration Time”).

As of the Expiration Time, $292,571,000 aggregate principal amount of the outstanding 2018 Notes (representing approximately 97.52% of the outstanding 2018 Notes) had been validly tendered and not validly withdrawn. All $292,571,000 aggregate principal amount of such notes were validly tendered before the early tender deadline on March 14, 2014 and purchased by PHI on March 17, 2014, and no additional 2018 Notes were tendered after such early tender deadline. Currently, $7,429,000 aggregate principal amount of the 2018 Notes remain outstanding.

On March 17, 2014, PHI called for redemption all of the 2018 Notes that remain outstanding following consummation of the Tender Offer at a “make-whole” redemption price to be determined prior to the redemption date in accordance with the terms of the 2018 Notes and the indenture governing the 2018 Notes (the “2018 Indenture”), plus accrued and unpaid interest relating to such redeemed notes up to, but not including, the redemption date, if any. The redemption is expected to occur on April 16, 2014 in accordance with the terms of the 2018 Indenture.

This press release is neither (i) an offer to purchase, nor a solicitation of an offer to sell, any securities nor (ii) a notice of redemption of any securities.

The complete terms and conditions of the tender offer and consent solicitation are set forth in the Offer to Purchase and related letter of transmittal, which have been previously furnished to the holders of the 2018 Notes.
