Membership Interest Purchase Agreement.

On March 20, 2020, a certain indirect wholly-owned subsidiary (the “Purchaser”) of SEACOR Marine Holdings Inc. (the “Company”) entered into a membership interest purchase agreement with the Company, Montco Offshore, LLC (the “Seller”) and Lee Orgeron, the principal of the Seller (such agreement, the “MIPA”), pursuant to which the Purchaser purchased the 28% minority equity interest in Falcon Global Holdings LLC (“Falcon Global Holdings”) held by the Seller (the “Equity Purchase”) in exchange for a private placement of 900,000 shares of common stock, par value $0.01 per share, of the Company (the “Consideration Shares”) that were issued to Seller as purchase consideration. The purchase resulted in the Purchaser owning 100% of Falcon Global Holdings. The issuance of the Consideration Shares pursuant to the MIPA was made in reliance upon the exemption from registration provided under Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”). In determining that the issuance of the Consideration Shares qualified for an exemption under Section 4(a)(2), the Company relied on the following facts: (i) the Seller was an accredited investor or qualified institutional buyer, (ii) the Company did not use any form of general solicitation or advertising to offer the common stock and (iii) the investment intent of the Seller.

Registration Rights Agreement.

In connection with the Equity Purchase, the Company and the Seller entered into a Registration Rights Agreement, dated March 20, 2020 (the “Registration Rights Agreement”). Pursuant to the Registration Rights Agreement, the Company agreed to use its commercially reasonable efforts to file a shelf registration statement with the Securities and Exchange Commission (the “Commission”) on Form S-3 under the Securities Act no later than 60 days after the date of the Registration Rights Agreement (such date, except as noted below, the “Mandatory Shelf Filing Date”) providing for registration and resale of the Consideration Shares. If the Company is not eligible to file and use a Form S-3 to register resales of the Consideration Shares by the Seller by the Mandatory Shelf Filing Date, it is required to use its commercially reasonable efforts to file a Form S-1 under the Securities Act (or such other form of registration statement as is then available to permit resales by holders of the Consideration Shares on a continuous or delayed basis) providing for registration and resale of the Consideration Shares. Under the Registration Rights Agreement, the Company is required to use its commercially reasonable efforts to cause the registration statement to be declared effective under the Securities Act by the Commission as soon as reasonably practicable after the Mandatory Shelf Filing Date and keep the registration statement continuously effective under the Securities Act until the earlier of (A) the date when all of the Consideration Shares covered by such registration statement have been sold and (B) the date on which all of the Consideration Shares cease to be registrable securities under the Registration Rights Agreement. The Registration Rights Agreement provides the Company with customary blackout rights and requires the Company to pay liquidating damages under certain circumstances if the registration is not filed or declared effective by specified dates. The foregoing description of Registration Rights Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as Exhibit 4.1 hereto and the terms of which are incorporated herein by reference.

On March 20, 2020, the Company issued a press release announcing the Equity Purchase. A copy of the press release is included as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

The Registration Statement when effective (including the documents incorporated therein by reference) will comply as to form in all material respects with all applicable requirements of the Securities Act and the Exchange Act and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading (in the case of any prospectus contained in such Registration Statement, in the light of the circumstances under which a statement is made). As soon as practicable following the date that the Registration Statement becomes effective, but in any event within two (2) Business Days of such date, the Company shall provide the Holder with written notice of the effectiveness of the Registration Statement.

(b) the Company may, upon written notice to any Selling Holder whose Registrable Securities are included in the Registration Statement or other registration statement contemplated by this Agreement, suspend such Selling Holder’s use of any prospectus which is a part of the Registration Statement or other registration statement (in which event the Selling Holder shall discontinue sales of the Registrable Securities pursuant to the Registration Statement or other registration statement contemplated by this Agreement but may settle any previously made sales of Registrable Securities) if (i) the Company determines that it would be required to make disclosure of material information in the Registration Statement that the Company has a bona fide business purpose for preserving as confidential, (ii) the Company has experienced some other material non-public event the disclosure of which at such time, in the good faith judgment of the Company, would adversely affect the Company or (iii) the Company determines that it is required to amend or supplement the affected Registration Statement or the related prospectus so that such Registration Statement or prospectus does not include an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in the case of the prospectus in light of the circumstances under which they were made, not misleading; provided, however, in no event shall the Selling Holders be suspended from selling Registrable Securities pursuant to the Registration Statement or other registration statement for a period that exceeds an aggregate of 90 days in any 180-day period. Upon disclosure of such information or the termination of the condition described above, the Company shall provide prompt notice to the Selling Holders whose Registrable Securities are included in the Registration Statement, and shall promptly terminate any suspension of sales it has put into effect and shall take such other reasonable actions to permit registered sales of Registrable Securities as contemplated in this Agreement.

The Company will not name a Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act in any Registration Statement without such Holder’s consent. If the staff of the Commission requires the Company to name any Holder as an underwriter as defined in Section 2(a)(11) of the Securities Act, and such Holder does not consent thereto, then such Holder’s Registrable Securities shall not be included on the Registration Statement and the Company shall have no further obligations hereunder with respect to Registrable Securities held by such Holder or be required to pay any Liquidated Damages to the Holder.

Each Selling Holder, upon receipt of notice from the Company of the happening of any event of the kind described in subsection (e) of this Section 2.04 or the exercise of its rights pursuant to Section 2.03, shall forthwith discontinue offers and sales of the Registrable Securities by means of a prospectus or prospectus supplement until such Selling Holder’s receipt of the copies of the supplemented or amended prospectus contemplated by subsection (e) of this Section 2.04 or until it is advised in writing by the Company that the use of the prospectus may be resumed and has received copies of any additional or supplemental filings incorporated by reference in the prospectus, and, if so directed by the Company, such Selling Holder will deliver to the Company (at the Company’s expense) all copies in their possession or control, other than permanent file copies then in such Selling Holder’s possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice.

7

omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, and the Company will reimburse such seller and each such director, officer, and controlling Person for any legal or any other expenses reasonably incurred by them in connection with investigating or defending any such loss, claim, liability, action or proceeding; provided that the Company shall not be liable in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect thereof) or expense arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, any such preliminary prospectus, final prospectus, summary prospectus, amendment or supplement in reliance upon and in conformity with information regarding such seller furnished by such seller (or any representative of such seller) to the Company in writing or electronically specifically stating that it is for use in the preparation thereof. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of such seller or any such director, officer or controlling Person and shall survive the transfer of such securities by such seller.

(b) Indemnification by the Sellers. The Company may require, as a condition to including any Registrable Securities in any registration statement filed pursuant to Section 2.01 above, that the Company shall have received an undertaking satisfactory to it from the prospective seller of such securities, to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 2.07(a) above) the Company, each director of the Company, each officer of the Company and each other Person, if any, who controls the Company within the meaning of the Securities Act, with respect to any statement or alleged statement in or omission or alleged omission from such registration statement, any preliminary prospectus, final prospectus or summary prospectus contained therein, or any amendment or supplement thereto, if such statement or alleged statement or omission or alleged omission was made in reliance upon and in conformity with information regarding such seller furnished by such seller (or any representative of such seller) to the Company in writing or electronically specifically stating that it is for use in the preparation of such registration statement, preliminary prospectus, final prospectus, summary prospectus, amendment or supplement. The maximum liability of each seller for any such indemnification shall not exceed the amount of proceeds actually received by such seller from the sale of his/its Registrable Securities. Such indemnity shall remain in full force and effect, regardless of any investigation made by or on behalf of the Company or any such director, officer or controlling Person and shall survive the transfer of such securities by such seller.

(c) Notices of Claims, etc. Promptly after receipt by an indemnified party of notice of the commencement of any action or proceeding involving a claim referred to in Section 2.07(a) or (b) above, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the latter of the commencement of such action; provided that the failure of any indemnified party to give notice as provided herein shall not relieve the indemnifying party of its obligations under Section 2.07(a) or (b) above, except to the extent that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an indemnified party, unless in such indemnified party’s reasonable judgment a conflict of interest between such indemnified and indemnifying parties may exist in respect of such claim, the indemnifying party shall be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel reasonably satisfactory to such indemnified party, and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof. No indemnifying party shall, without the consent of the indemnified party, consent to entry of any judgment or enter into any settlement which does not include as an unconditional term thereof the giving by the claimant or plaintiff to such indemnified party of a release from all liability in respect to such claim or litigation. No indemnified party shall settle any claim for which indemnity maybe sought under this Agreement without the consent of the indemnifying party.

Exhibit 99.1

SEACOR MARINE CONSOLIDATES OWNERSHIP OF

LIFTBOAT BUSINESS IN SHARE TRANSACTION

Houston, Texas

March 20, 2020

FOR IMMEDIATE RELEASE - SEACOR Marine Holdings Inc. (NYSE:SMHI) (the “Company” or “SEACOR Marine”), a leading provider of marine and support transportation services to offshore oil and natural gas and wind farm facilities worldwide, today announced that a wholly-owned subsidiary of the Company acquired the remaining 28% of the equity interests in Falcon Global Holdings LLC (“FGH”) that it did not already own from Montco Offshore, LLC (“Montco Offshore”), resulting in 100% ownership of FGH by the Company. As consideration for the acquisition, the Company will issue 900,000 shares of its common stock in a private placement to Montco Offshore.

The acquisition consolidates the Company’s ownership of 14 liftboats with vessels currently working in the U.S. Gulf of Mexico, Mexico, and Saudi Arabia. Liftboats provide a self-propelled, stable platform to perform support for wind farm installation and maintenance, and services to oil and gas platforms and structures, including platform construction, inspection, maintenance and removal, well intervention and work-over, well production enhancement, well plug and abandonment, pipeline installation and maintenance and diving operations.

John Gellert, SEACOR Marine’s Chief Executive Officer, commented “We are pleased to complete this acquisition at the current price levels and expand our equity base during these challenging times. Consolidating our ownership of the liftboat fleet will allow us to manage the business with full flexibility going forward, which we believe will create value for our shareholders.”

SEACOR Marine provides global marine and support transportation services to offshore oil and natural gas and windfarm facilities worldwide. SEACOR Marine and its joint ventures operate a diverse fleet of offshore support and specialty vessels that deliver cargo and personnel to offshore installations; handle anchors and mooring equipment required to tether rigs to the seabed; tow rigs and assist in placing them on location and moving them between regions; provide construction, well workover and decommissioning support; and carry and launch equipment used underwater in drilling and well installation, maintenance and repair. Additionally, SEACOR Marine’s vessels provide accommodations for technicians and specialists, safety support and emergency response services.

Certain statements discussed in this release as well as in other reports, materials and oral statements that the Company releases from time to time to the public constitute “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Generally, words such as “anticipate,” “estimate,” “expect,” “project,” “intend,” “believe,” “plan,” “target,” “forecast” and similar expressions are intended to identify forward-looking statements. Such forward-looking statements concern management’s expectations, strategic objectives, business prospects, anticipated economic performance and financial condition and other similar matters. Forward-looking statements are inherently uncertain and subject to a variety of assumptions, risks and uncertainties that could cause actual results to differ materially from those anticipated or expected by the management of the Company. These statements are not guarantees of future performance and actual events or results may differ significantly from these statements. Actual events or results are subject to significant known and unknown risks, uncertainties and other important factors, many of which are beyond the Company’s control. It should be understood that it is not possible to predict or identify all such factors. Consequently, the preceding should not be considered to be a complete discussion of all potential risks or uncertainties. Given these risk factors, investors and analysts should not place undue reliance on forward-looking statements. Forward-looking statements speak only as of the date of the document in which they are made. The Company disclaims any obligation or undertaking to provide any updates or revisions to any forward-looking statement to reflect any change in the Company’s expectations or any change in events, conditions or circumstances on which the forward-looking statement is based, except as required by law. It is advisable, however, to consult any further disclosures the Company makes on related subjects in its filings with the Securities and Exchange Commission, including Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K (if any). These statements constitute the Company’s cautionary statements under the Private Securities Litigation Reform Act of 1995.
