<div align='center'>“Authorized ≠ Issued”</div>

A quick note on something we’ve seen a few questions about:

Authorized ≠ Issued.

Authorized shares are the maximum number of shares a company is permitted to issue, while issued shares are the number of shares the company actually sold or granted.

Increasing authorized shares does not mean they will necessarily be issued, but they will be available to be issued. It’s about flexibility and optionality — having the option to fund projects with equity enables the company to optimize the debt to equity capital structure of the company and its partnerships to grow shareholder value.

If you’re a shareholder, please take a moment to vote FOR all proposals in this Special Meeting proxy on November 7, 2025, at 10 a.m. ET. Every vote matters.

Increasing our authorized shares simply gives Soluna flexibility. It doesn’t mean those shares will be issued immediately, or ever.

Think of it as expanding the toolbox, not using every tool at once.

Authorizing up to 375M shares allows Soluna to:

| ● | Fund                                           
 growth opportunities when the timing is right. |

| ● | Support                                    
 partnerships and financings strategically. |

| ● | Compete                                                    
 on the same playing field as peers, without overextending. |

This grants your Board and Management access to an additional source of capital to put to work for our shareholders.

Vote FOR all proposals today.
