Item 7.01. Regulation FD Disclosure

Attached as Exhibit 99.1 and incorporated by reference into this Item 7.01 is a copy of an investor relations update to be presented at DNB's 11th Annual Oil, Offshore & Shipping Conference in Oslo, Norway by GulfMark Offshore, Inc. (the “Company”) on March 7, 2018 by Quintin Kneen, the Company’s President and Chief Executive Officer.

The information in this Item 7.01, including Exhibit 99.1 attached hereto, is being furnished and shall not be deemed “filed” for the purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that Section. The information in this Item 7.01 shall not be incorporated by reference into any registration statement or other document pursuant to the Securities Act of 1933, as amended (the “Securities Act”), except as otherwise expressly stated in such filing.

The presentation referenced in this report and any oral or written statements made in connection with the presentation that are not historical facts are “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements. Forward-looking statements include, without limitation, any statement that may project, indicate or imply future results, events, performance or achievements. In addition, any statement concerning future financial performance, ongoing business strategies or prospects are also forward-looking statements as so defined. Such statements may include, but are not limited to, statements concerning anticipated cash flows, income, costs, liabilities, profits, future production of oil and gas, future capital expenditures and drilling of wells and future financial or operating results. These forward-looking statements are based on the Company’s current expectations and beliefs concerning future developments and their potential effect on the Company. While management believes that these forward-looking statements are reasonable as and when made, there can be no assurance that future developments affecting the Company will be those that the Company anticipates. Forward-looking statements involve significant risks and uncertainties (many of which are beyond the Company’s control) and assumptions that could cause actual results to differ materially from present expectations or projections. Important factors that could cause actual results to differ materially from those in the forward-looking statements include, but are not limited to: risks of insufficient access to sources of liquidity; operational risk; the price of oil and gas and its effect on offshore drilling, vessel utilization and day rates; industry volatility; fluctuations in the size of the offshore marine vessel fleet in areas where we operate; changes in competitive factors; and other material factors that are described from time to time in the Company’s filings with the SEC, including the Company’s Annual Report on Form 10-K, Quarterly Reports on Form 10-Q and Current Reports on Form 8-K. Consequently, these forward-looking statements should not be regarded as representations that the projected or anticipated outcomes can or will be achieved. Given these risks and uncertainties, investors should not place undue reliance on forward-looking statements. Each forward-looking statement speaks only as of the date of such statement, and the Company expressly disclaims any obligation or undertaking to publicly update or revise any forward-looking statement after the date it is made, whether as a result of new information, future events or otherwise.
