Key Points from the 2025 Annual Report

• Company Identity and Structure:
  • Soluna Holdings, Inc. is a non-accelerated filer and a smaller reporting company, not an emerging growth company.
  • The company’s common stock and 9.0% Series A Cumulative Perpetual Preferred Stock are listed on The Nasdaq Stock Market LLC under tickers SLNH and SLNHP, respectively.
• Share Capital and Market Value:
  • As of March 20, 2026, the company had 111,381,064 shares of common stock outstanding.
  • The aggregate market value of voting and non-voting common equity held by non-affiliates as of June 30, 2025, was approximately \$8.28 million, based on a closing price of \$0.58 per share.
• Filing and Compliance:
  • Soluna has filed all required reports under Section 13 or 15(d) of the Exchange Act for the preceding 12 months and submitted all Interactive Data Files as required by Regulation S-T.
  • The company is not a shell company and has not restated financials due to error corrections or incentive-based compensation recovery analysis.
  • No indication of auditor attestation for internal control effectiveness (Section 404(b) of Sarbanes-Oxley Act).
• Outstanding Securities and Shareholder Structure:
  • Common stock and 9.0% Series A Cumulative Perpetual Preferred Stock are the primary equity securities.
  • There are also Series B Preferred Stock and various classes of warrants and restricted stock units (RSUs), some of which are listed as antidilutive and excluded from earnings per share calculations, indicating potential dilution risk if converted in the future.
• Key Risks and Disclosures:
  • There is significant customer concentration risk, especially linked to “Project Dorothy1A” and “Project Dorothy2”. Data hosting revenue is a major segment, and loss or change in these customers could materially impact revenue.
  • Soluna’s business includes cryptocurrency mining and data hosting, both of which are subject to market risk, regulatory risk, and volatility in underlying assets and customer base.
  • The company has disclosed operating segments, consolidated entities, and investments in joint ventures and subsidiaries, such as KKSL JV Co, Harmattan Energy Limited, and DVSL Compute Co LLC, which can affect consolidated results and risk profile.
• Governance, Compensation, and Related Party Transactions:
  • The report contains sections on executive compensation, director independence, and related party transactions, which are available for scrutiny but not detailed in the excerpt above.
• Forward-Looking Statements and Cautionary Notes:
  • The company provides a cautionary note on forward-looking statements, warning investors that actual results could differ materially from those indicated, due to risks related to operations, regulation, and market conditions in the cryptocurrency and data hosting sectors.

Potentially Price-Sensitive and Strategic Insights

• Low Public Float and Share Price: With a public float of just over \$8 million and a low share price, the company’s stock could be highly volatile and susceptible to large price swings with relatively modest trading volume.
• Customer Concentration Risk: The company’s reliance on a small number of major customers for data hosting revenue represents a significant risk. Any changes in these relationships or contracts could materially affect revenue and share value.
• Complex Capital Structure: The presence of multiple classes of preferred stock, warrants, and antidilutive securities means that future share dilution is possible, which could impact existing shareholders’ value.
• Cryptocurrency Exposure: Involvement in cryptocurrency mining exposes the firm to the volatile crypto market, regulatory risk, and fluctuations in crypto asset prices, which have proven to be highly sensitive to global macroeconomic and regulatory events.
• No Auditor Attestation on Internal Control: The company’s internal control over financial reporting has not been attested by its auditor. This may be a concern for investors focused on governance and financial integrity.

What Shareholders Should Watch For

• Upcoming Financial Results: Investors should closely monitor quarterly and annual results, especially as they relate to customer concentration, contract renewals, and revenue diversification.
• Potential Dilution: Holders should be aware of possible dilution from the conversion of preferred stock, warrants, and RSUs.
• Regulatory Developments: Any changes in the regulatory landscape for cryptocurrency mining or data hosting could have a swift and material impact on Soluna’s business model and share price.
• Mergers, Acquisitions, or Joint Ventures: The company’s involvement in various joint ventures and subsidiaries could lead to strategic changes, asset sales, or acquisitions, which may move the share price.

Conclusion

Soluna Holdings, Inc. faces several critical business, operational, and market risks that shareholders should closely monitor. The company’s low public float, reliance on a few major customers, involvement in the volatile cryptocurrency sector, and complex capital structure all contribute to potentially high share price volatility. Investors are advised to review official filings in detail and stay alert to future disclosures, especially around customer contracts, regulatory matters, and the company’s capital markets activity.
