Provides Financial Flexibility to Capitalize on Growth Opportunities

Soluna Holdings, Inc. (Nasdaq: SLNH) (formerly Mechanical Technology), a developer of green data centers for cryptocurrency mining and other intensive computing, announced today that it has filed a "universal shelf" registration statement on Form S-3 with the Securities and Exchange Commission (SEC) for the registration of Common Stock, Preferred Stock, Debt Securities, Warrants, Units, and the Subscription Rights, as well as the resale of certain securities privately offered by the Company.

When declared effective by the SEC, the shelf registration statement will allow the Company to raise capital, up to an aggregate of $150.0 million, excluding the resale of certain securities privately offered by the Company. The specifics of any future offering, along with the prices and terms of any such securities and the use of proceeds of a particular offering, will be determined at the time of any such offering and will be described in a prospectus supplement filed in connection with such offering. Once declared effective by the SEC, the shelf registration statement will be in effect for three years, or such shorter period that the securities registered under the shelf registration statement have been issued or sold.

“Today’s shelf registration statement was filed in the ordinary course of business,” said Michael Toporek, Soluna’s CEO.  "Over this past year, we have been executing against an aggressive growth plan and achieved several critical milestones as we continue to build and transform our company. With the filing of this registration statement, we believe we gain important financial flexibility and access to additional forms of growth capital, especially non-dilutive instruments.” 

The registration statement on Form S-3 has been filed with the SEC but is not yet effective. Securities may not be sold nor may offers to buy such securities be accepted prior to the time that the registration statement is declared effective by the SEC. This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of any securities in any state in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities law of any such state.

Any offering of the securities will be made solely by means of a prospectus and an accompanying prospectus supplement relating to that offering.  The Company will not receive any proceeds from any sale of securities by the selling stockholders.
