at

Pursuant to the Offer to Purchase dated December 18, 2020

by

Safari Merger Subsidiary, Inc.

a wholly owned subsidiary of

Safari Parent, Inc.

Safari Merger Subsidiary, Inc., a Delaware corporation (“Purchaser”), is offering to purchase , subject to certain conditions, including the satisfaction of the Minimum Tender Condition, as described and defined below, any and all of the issued and outstanding shares of common stock, par value $0.01 per share (the “Shares”), of SEACOR Holdings Inc., a Delaware corporation (“SEACOR”), at a price per Share of $41.50, net to the holder in cash, without interest (the “Offer Price”) and subject to any withholding of taxes, upon the terms and subject to the conditions described in the Offer to Purchase, dated December 18, 2020 (together with any amendments or supplements thereto, the “Offer to Purchase”), and in the related Letter of Transmittal (together with any amendments or supplements thereto, the “Letter of Transmittal” and, together with the Offer to Purchase, the “Offer”). Purchaser is a wholly owned subsidiary of Safari Parent, Inc., a Delaware corporation (“Parent”). Parent is indirectly controlled by affiliates of American Industrial Partners Capital Fund VII, L.P., a Delaware limited partnership.

The Offer is being made in connection with the Agreement and Plan of Merger, dated as of December 4, 2020 (together with any amendments or supplements thereto, the “Merger Agreement”), among SEACOR, Parent and Purchaser, pursuant to which, after the completion of the Offer and the satisfaction or waiver of certain conditions, Purchaser will be merged with and into SEACOR in accordance with Section 251(h) of the General Corporation Law of the State of Delaware (as amended, the “DGCL”), and SEACOR will be the surviving corporation and a wholly owned subsidiary of Parent (such merger, the “Merger”). At the effective time of the Merger, each Share outstanding immediately prior to the effective time of the Merger (other than (i) Shares held by SEACOR (or held in SEACOR’S treasury), (ii) Shares held by Parent, Purchaser or any other direct or indirect wholly owned subsidiary of Parent and (iii) Shares held by stockholders who are entitled to appraisal rights under Section 262 of the General Corporation Law of the State of Delaware (“DGCL”) and have properly exercised and perfected their respective demands for appraisal of such Shares in the time and manner provided in Section 262 of the DGCL and, as of the effective time of the Merger, have neither effectively withdrawn nor lost their rights to such appraisal and payment under the DGCL) will be converted into the right to receive consideration equal to the Offer Price payable, without any interest, and subject to any withholding taxes, in accordance with the terms and conditions of the Merger Agreement. As a result of the Merger, SEACOR will cease to be a publicly-traded company and will become wholly owned by Parent. Under no circumstances will interest be paid on the purchase price for Shares, regardless of any extension of the Offer or any delay in making payment for Shares. Subject to the conditions specified in the Merger Agreement, the Merger will become

effective as soon as practicable after the consummation of the Offer, without a vote of SEACOR’S stockholders to adopt the Merger Agreement, in accordance with Section 251(h) of the DGCL. The Merger Agreement is more fully described in the Offer to Purchase.

Tendering stockholders of SEACOR who have Shares registered in their names and who tender directly to American Stock Transfer & Trust Company (the “Depository”) will not be obligated to pay brokerage fees or commissions or, except as set forth in the Letter of Transmittal, transfer taxes on the purchase of Shares by Purchaser pursuant to the Offer. Stockholders who hold their Shares through a broker or bank should consult with such institution as to whether it charges any service fees or commissions.

THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT ONE MINUTE AFTER 11:59 P.M., EASTERN TIME, ON JANUARY 20, 2021 (SUCH DATE, OR ANY SUBSEQUENT DATE TO WHICH THE EXPIRATION OF THE OFFER IS EXTENDED, THE “EXPIRATION DATE”), UNLESS THE OFFER IS EXTENDED OR EARLIER TERMINATED.

The Offer is conditioned upon, among other things, (a) the Merger Agreement not having been terminated in accordance with its terms (the “Termination Condition”) and (b) the satisfaction of:

(i) the Minimum Tender Condition (as described below);

(ii) the HSR Condition (as described below); and

(iii) the Governmental Impediment Condition (as described below).

The Offer is not subject to a financing condition. The Minimum Tender Condition requires that the number of Shares validly tendered and not validly withdrawn (excluding Shares tendered in the Offer pursuant to guaranteed delivery procedures that have not yet been “received” (as such term is defined in Section 251(h)(6)(f) of the DGCL), together with all other Shares (if any) beneficially owned by Parent and its affiliates, represents one Share more than 66 2/3% of the total number of Shares outstanding at the time of the expiration of the Offer. The HSR Condition requires that each consent, approval or clearance with respect to, or termination or expiration of any applicable waiting period (or any extension thereof) under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 as amended, has been obtained, terminated or expired. The Governmental Impediment Condition requires that no governmental entity of competent jurisdiction has enacted or promulgated any law, statute, rule, regulation, executive order, decree, ruling, injunction or other order (whether temporary, preliminary or permanent) to prohibit, restrain, enjoin or make illegal the consummation of the Offer or the Merger that remains in effect. The Offer is also subject to other conditions as described in the Offer to Purchase (collectively, the “Offer Conditions”). See Section 13—”Conditions of the Offer” of the Offer to Purchase.

After careful consideration, the SEACOR board of directors has, subject to the terms and upon the conditions set forth in the Merger Agreement: (i) determined that the Merger Agreement and the transactions contemplated thereby, including the Offer and the Merger, are fair to, and in the best interests of, SEACOR and its stockholders, (ii) declared it advisable to enter into the Merger Agreement, (iii) approved the execution, delivery and performance by SEACOR of the Merger Agreement and the consummation of the transactions contemplated thereby, including the Offer and the Merger, (iv) resolved that the Merger shall be effected under Section 251(h) of the DGCL, and (v) resolved to recommend that the stockholders of SEACOR accept the Offer and tender their Shares to Purchaser pursuant to the Offer.

SEACOR will file a Solicitation/Recommendation Statement on Schedule 14D-9 (the “Schedule 14D-9”) with the United States Securities and Exchange Commission (the “SEC”) and disseminate the Schedule 14D-9 to SEACOR’S stockholders with the Offer to Purchase. The Schedule 14D-9 will include a description of the SEACOR board of directors’ reasons for authorizing and approving the Merger Agreement and the transactions contemplated thereby and therefore stockholders are encouraged to review the Schedule 14D-9 carefully and in its entirety.

The Merger Agreement contains provisions to govern the circumstances in which Purchaser is required to extend the Offer and in which Parent is required to cause Purchaser to extend the Offer. Specifically, the Merger Agreement provides that Purchaser shall (and Parent shall cause Purchaser to) extend the Offer (i) if, as of the then-scheduled Expiration Date, any Offer Condition is not satisfied (unless such condition is waivable by Purchaser or Parent and has been waived), for additional periods of up to 10 business days per extension to permit such Offer Condition (as defined in the Merger Agreement) to be satisfied and (ii) from time to time for any period required by any legal requirement, any interpretation or position of the SEC or its staff or the NYSE applicable to the Offer. Notwithstanding the foregoing, in no event will Purchaser be required to extend the Offer beyond April 5, 2021 (such date, the “End Date”) or the earlier termination of the Merger Agreement, and in no event will Purchaser be permitted to extend the Offer beyond the End Date or the earlier termination of the Merger Agreement without SEACOR’S prior written consent.

The purpose of the Offer and the Merger is for Parent and its affiliates, through Purchaser, to acquire control of, and the entire equity interests in, SEACOR. Following the consummation of the Offer, subject to the satisfaction or waiver of the conditions set forth in the Merger Agreement, Parent and Purchaser intend to effect the Merger. No appraisal rights are available to holders of Shares in connection with the Offer. However, if the Merger is consummated, a stockholder of SEACOR that has not tendered its Shares in the Offer will have rights under Section 262 of the DGCL to dissent from the Merger and demand appraisal of, and obtain payment in cash for the “fair value” of, that stockholder’s Shares.

On the terms and subject to the conditions of the Merger Agreement and the applicable rules and regulations of the SEC, Purchaser expressly reserves the right to (i) increase the amount of cash constituting the Offer Price (except to the extent required under the Merger Agreement when applicable), (ii) waive any Offer Condition (to the extent permitted under applicable Law (as defined in the Merger Agreement)) and (iii) make any other changes in the terms and conditions of the Offer that are not inconsistent with the Merger Agreement. However, without the consent of SEACOR, Parent and Purchaser are not permitted to (i) decrease the Offer Price, (ii) change the form of consideration payable in the Offer, (iii) decrease the maximum number of Shares sought to be purchased in the Offer, (iv) impose conditions or requirements to the Offer in addition to the Offer Conditions, (v) amend, modify or waive the Minimum Tender Condition, the Termination Condition, the HSR Condition or the Governmental Impediment Condition, (vi) otherwise amend or modify any of the other terms of the Offer in a manner that adversely affects, or would reasonably be expected to adversely affect, any holder of Shares in its capacity as such, (vii) withdraw or terminate the Offer or accelerate, extend or otherwise change the Expiration Date except as provided in the Merger Agreement, or (viii) provide any “subsequent offering period” (or any extension thereof) within the meaning of applicable SEC rules and regulations.

Any extension, waiver or amendment of the Offer or termination of the Offer will be followed, as promptly as practicable, by public announcement thereof, such announcement in the case of an extension to be issued no later than 9:00 a.m., Eastern Time, on the next business day after the previously scheduled Expiration Date.

For purposes of the Offer, Purchaser will be deemed to have accepted for payment, and thereby purchased, Shares validly tendered, and not properly withdrawn, prior to the expiration of the Offer if and when Purchaser gives oral or written notice to the Depository of Purchaser’s acceptance for payment of such Shares pursuant to the Offer. Upon the terms and subject to the conditions of the Offer, payment for Shares accepted for payment pursuant to the Offer will be made by deposit of the aggregate Offer Price for such Shares with the Depository, which will act as paying agent for the tendering stockholders for the purpose of receiving payments from Purchaser and transmitting such payments to the tendering stockholders. No interest will be paid on the Offer Price for Shares, regardless of any extension of the Offer or any delay in making payment for Shares.

In all cases, payment for Shares tendered and accepted for payment pursuant to the Offer will be made only after timely receipt by the Depository of (a) certificates for such Shares (“Share Certificates”) or timely confirmation of the book-entry transfer of such Shares (“Book-Entry Confirmations”) into the Depository’s account at The Depository Trust Company (“DTC”) pursuant to the procedures set forth in the Offer to Purchase,

3

(b) a Letter of Transmittal, properly completed and duly executed, with any required signature guarantees (or, in the case of a book-entry transfer, an Agent’s Message (as defined in the Offer to Purchase) in lieu of the Letter of Transmittal) and (c) any other documents required by the Letter of Transmittal. Accordingly, tendering stockholders may be paid at different times depending upon when Share Certificates or Book-Entry Confirmations with respect to Shares are actually received by the Depository.

Pursuant to Section 14(d)(5) of the Securities Exchange Act of 1934, as amended, Shares tendered pursuant to the Offer may be withdrawn at any time prior to the expiration of the Offer and, unless theretofore accepted for payment by Purchaser pursuant to the Offer, may also be withdrawn at any time after February 16, 2021, which is the 60th day after the date of the commencement of the Offer.

For a withdrawal of Shares to be effective, a written notice of withdrawal must be timely received by the Depository at its address set forth on the back cover of the Offer to Purchase. Any such notice of withdrawal must specify the name of the person having tendered the Shares to be withdrawn, the number of Shares to be withdrawn and the name of the record holder of the Shares to be withdrawn, if different from that of the person who tendered such Shares. The signature(s) on the notice of withdrawal must be guaranteed by an Eligible Institution (as defined in the Offer to Purchase), unless such Shares have been tendered for the account of any Eligible Institution. If Shares have been tendered pursuant to the procedures for book-entry transfer as set forth in the Offer to Purchase, any notice of withdrawal must specify the name and number of the account at DTC to be credited with the withdrawn Shares and must otherwise comply with DTC’s procedures. If certificates representing the Shares to be withdrawn have been delivered or otherwise identified to the Depository, the name of the registered holder and the serial numbers shown on such certificates must also be furnished to the Depository as aforesaid prior to the physical release of such certificates.

All questions as to the form and validity (including time of receipt) of any notice of withdrawal will be determined by Purchaser, in its sole discretion, which determination shall be final and binding, subject to the rights of tendering stockholders to challenge Purchaser’s determination in a court of competent jurisdiction. No withdrawal of tendered Shares shall be deemed to have been properly made until all defects and irregularities have been cured or waived. None of Parent, Purchaser or any of their respective affiliates or assigns, the Depository, the Information Agent (listed below), or any other person will be under any duty to give notification of any defects or irregularities in any notice of withdrawal or incur any liability for failure to give such notification. Withdrawals of tendered Shares may not be rescinded, and any Shares properly withdrawn will be deemed not to have been validly tendered for purposes of the Offer. However, withdrawn Shares may be retendered by following one of the procedures for tendering Shares described in the Offer to Purchase at any time prior to the expiration of the Offer.

The information required to be disclosed by paragraph (d)(1) of Rule 14d-6 under the Securities and Exchange Act of 1934, as amended, is contained in the Offer to Purchase and is incorporated herein by reference.

SEACOR has provided Purchaser with SEACOR’S stockholder list and securities position listings for the purpose of disseminating to the holders of Shares information regarding the Offer. The Offer to Purchase and related Letter of Transmittal will be mailed to record holders of Shares whose names appear on SEACOR’S stockholder list and will be furnished to brokers, dealers, commercial banks, trust companies and similar persons whose names, or the names of whose nominees, appear on the stockholder list or, if applicable, who are listed as participants in a clearing agency’s security position listing for subsequent transmittal to beneficial owners of Shares.

The receipt of the Offer Price for Shares in the Offer or consideration for Shares in the Merger will be a taxable transaction for U.S. federal income tax purposes. Stockholders of SEACOR should consult with their tax advisors as to the particular tax consequences of the Offer and the Merger to them.
