SEACOR HOLDINGS ANNOUNCES NOTIFICATION FOR

REPURCHASE OF 2.50% CONVERTIBLE SENIOR NOTES AT OPTION

OF HOLDERS

Fort Lauderdale, Florida

November 13, 2017

FOR IMMEDIATE RELEASE - SEACOR Holdings Inc. (NYSE: CKH) (“SEACOR” or the “Company”) announced today that it is notifying holders of its 2.50% Convertible Senior Notes due 2027 (CUSIP Number: 811904 AM3) (the “Notes”) that they have the right to surrender their Notes for repurchase by SEACOR for cash pursuant to their option (the “Put Option”) under the Indenture, dated as of December 11, 2012, as amended or supplemented from time to time, (the “Indenture”) between SEACOR and Wells Fargo Bank, National Association, a national banking association, as trustee and paying agent (the “Trustee” or “Paying Agent”). The Put Option entitles each holder of the Notes to require SEACOR to repurchase any and all of such holder’s outstanding Notes on December 19, 2017 (the “Repurchase Date”) at a purchase price in cash (the “Repurchase Price”) equal to 100% of the principal amount of the Notes, plus accrued and unpaid interest thereon up to, but excluding, the Repurchase Date.

The opportunity to exercise the Put Option commenced on November 13, 2017 and expires at 5:00 p.m., New York City time, on December 18, 2017, which is the first business day immediately preceding the Repurchase Date. In order to exercise the Put Option and receive the Repurchase Price, or validly withdraw Notes previously surrendered, a holder must follow the procedures set forth in the Issuer Repurchase Notice given by SEACOR today. SEACOR will accept for payment all validly surrendered and not validly withdrawn Notes promptly upon expiration of the Put Option. On or before 10:00 a.m., New York City time, on the Repurchase Date, SEACOR will deposit with the Paying Agent for the Notes the appropriate amount of cash required to pay the Repurchase Price of all validly surrendered and not validly withdrawn Notes, to be paid to the holders of record of the Notes. Unless SEACOR defaults in repurchasing Notes validly surrendered pursuant to the Put Option and not validly withdrawn, interest on those Notes will cease to accrue on the Repurchase Date. Notes in respect of which the Put Option is exercised will not be convertible in accordance with their terms, if otherwise convertible, unless surrender of those Notes is validly withdrawn.

None of the Company, its Board of Directors or its officers is making any representation or recommendation to any Holder as to whether to exercise the Put Option. Beneficial owners and Holders should consult with their own financial and tax advisors and must make their own decision as to whether to exercise the Put Option and, if so, the principal amount of notes for which the Put Option should be exercised.

Wells Fargo Bank, National Association is the Trustee and Paying Agent with respect to the Notes. Its address is:

At SEACOR’s request, the Trustee is delivering an Issuer Repurchase Notice relating to the Put Option to all registered holders of the Notes. In addition, SEACOR will file the Issuer Repurchase Notice with a Tender Offer Statement on Schedule TO with the Securities and Exchange Commission (“SEC”) today. Holders of Notes and other interested parties are urged to read the Issuer Repurchase Notice and other relevant documents filed with the SEC when they become available because they will contain important information about SEACOR and the repurchase. Materials filed with the SEC are available without charge at the SEC’s website, www.sec.gov. Documents filed with the SEC may also be obtained without charge at SEACOR’s website, www.seacorholdings.com.

Copies of the Issuer Repurchase Notice and additional information relating to the procedure for the surrender of the Notes may also be obtained from Wells Fargo Bank, National Association by calling (800) 344-5128.

The Trustee has informed SEACOR that, as of this date, all custodians and beneficial holders of the Notes hold the Notes through The Depository Trust Company (“DTC”) accounts and that there are no certificated Notes in non-global form. Accordingly, all Notes surrendered for repurchase must be delivered through the transmittal procedures of DTC’s Automated Tender Offer Program, subject to the terms and conditions of that system. To exercise the Put Option and receive payment of the Repurchase Price, custodians and beneficial holders of the Notes must validly and timely deliver their Notes through DTC’s transmittal procedures and should not submit a physical repurchase notice to SEACOR, the Trustee or the Paying Agent. Notes delivered through DTC’s transmittal procedures for repurchase may be withdrawn only by complying with the withdrawal procedure of DTC.

This press release is for information only and is not an offer to purchase, a solicitation of an offer to purchase, or a solicitation of an offer to sell securities of SEACOR. The offer to repurchase the Notes will be only pursuant to, and the Notes may be surrendered only in accordance with, the Issuer Repurchase Notice dated November 13, 2017 and related materials.
