Item

3.01. Notice of Delisting or Failure to Satisfy a Continued Listing Rule or Standard; Transfer of Listing.

On

April 10, 2026, Soluna Holdings, Inc. (the “Company”) received written notice (the “Notice”) from The Nasdaq

Stock Market LLC (“Nasdaq”) that the closing bid price for the Company’s common stock, par value $0.001 per share (the

“Common Stock”), had been below $1.00 per share for the previous 30 consecutive business days, and that the Company is therefore

not in compliance with the minimum bid price requirement for continued listing on the Nasdaq Capital Market as set forth in Nasdaq Listing

Rule 5550(a)(2).

The

Notice has no immediate effect on the listing or trading of the Common Stock on the Nasdaq Capital Market.

In

accordance with the Nasdaq Listing Rule 5810(c)(3)(A), the Company has a period of 180 calendar days, or until October 7, 2026, to regain

compliance with the minimum bid price requirement. To regain compliance, the closing bid price of the Common Stock must meet or exceed

$1.00 per share for a minimum of ten consecutive business days during this 180-day period.

If

the Company is not in compliance by October 7, 2026, the Company may qualify for a second 180 calendar-day period to regain compliance.

If the Company does not qualify for, or fails to regain compliance during the second compliance period, then Nasdaq will notify the Company

of its determination to delist the Common Stock, at which point the Company would have an option to appeal the delisting determination

to a Nasdaq hearings panel.

The

Company intends to actively monitor the closing bid price of the Common Stock and may, if appropriate, consider implementing available

strategies to regain compliance with the minimum bid price requirement under the Nasdaq Listing Rules.

SIGNATURES

Pursuant

to the requirements of the Securities Exchange Act of 1934, as amended, the registrant has duly caused this report to be signed on its

behalf by the undersigned hereunto duly authorized.
