(To Prospectus Dated April 3, 2020)

Stabilis Energy, Inc.

2,769,787 Shares of Common Stock

This prospectus supplement no. 1 (the “Supplement”) supplements information contained in the prospectus dated April 3, 2020 (the “Prospectus”) relating to the offering for resale from time to time by the selling stockholders identified therein of up to an aggregate of 2,769,787 shares of common stock, which the selling stockholders acquired pursuant to private placements between us and the selling stockholders. We registered the offer and sale of the shares of common stock to satisfy registration rights we granted to the selling stockholders.

The selling stockholders may also offer and sell the shares of common stock being offered by the Prospectus from time to time in public or private transactions, or both. These sales may occur at fixed prices, at market prices prevailing at the time of sale, at prices related to prevailing market prices, or at negotiated prices. The selling stockholders may sell shares to or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling stockholders, the purchasers of the shares, or both.

This Supplement is being filed to supersede and replace in its entirety the section entitled “Incorporation By Reference” in the Prospectus.

This Supplement is incorporated by reference into, and should be read in conjunction with, the Prospectus. This Supplement is not complete without, and may not be delivered or utilized except in connection with, the Prospectus, including any amendments or supplements thereto. Any statement contained in the Prospectus shall be deemed to be modified or superseded to the extent that information in this Supplement modifies or supersedes such statement. Any statement that is modified or superseded shall not be deemed to constitute a part of the Prospectus except as modified or superseded by this Supplement.

Our common stock is quoted on the OTCQX Best Market under the symbol “SLNG.” Our common stock previously traded on the Nasdaq Stock Market under the same symbol until October 3, 2019. On May 8, 2020, the closing price of our common stock on the OTCQX Best Market was $1.99 per share.
