[SCHEDULE 13G] HELIUS MEDICAL TECHNOLOGIES, INC. SEC Filing

Rhea-AI Filing Summary

Solana Rocket Holdings Limited and CHUNG Wai Shing jointly disclosed beneficial ownership in Helius Medical Technologies (HSDT). They report shared voting and dispositive power over 4,040,871 Class A shares, representing 9.99% of the outstanding shares based on 40,295,612 shares outstanding as of September 24, 2025. Solana Rocket directly holds 3,887,319 shares plus pre-funded warrants for up to 10,936,107 shares and cash stapled warrants for up to 14,823,426 shares. A Beneficial Ownership Blocker limits exercise of the warrants so the reporting persons are capped at 9.99% (calculated to include 153,552 shares issuable under partial exercise). The filing includes a joint filing agreement as Exhibit 99.1.

Positive

• Transparent disclosure of combined common stock and warrant positions totaling a capped 9.99% beneficial ownership
• Joint filing and attached agreement (Exhibit 99.1) clarify coordination between Solana Rocket and CHUNG Wai Shing

Negative

• Significant warrant exposure (pre-funded warrants for up to 10,936,107 shares and cash stapled warrants for up to 14,823,426 shares) indicates potential future dilution
• Concentration of control as Mr. CHUNG is identified as the controlling shareholder of Solana Rocket, implying shared voting power over 4,040,871 shares

Insights

Financial Analyst

TL;DR: Joint holders report a near-10% capped position using warrants and common stock, creating potential dilution if exercised.

The filing shows a material stake equivalent to 9.99% of HSDT, derived from a combination of common shares and extensive warrant positions held by Solana Rocket. The Beneficial Ownership Blocker constrains immediate conversion, so current reported percent reflects a capped, calculable exposure rather than full warrant conversion. For investors this clarifies ownership concentration and potential latent share supply from warrants, but does not change outstanding shares absent exercise.

Corporate Governance Expert

TL;DR: A controlling shareholder of the reporting entity may be deemed to beneficially own the securities, raising governance concentration questions.

The disclosure identifies Mr. CHUNG as the controlling shareholder of Solana Rocket and reports shared voting and dispositive power over 4,040,871 shares. The joint filing and explicit attribution of control provide transparency on who effectively influences these holdings. The Beneficial Ownership Blocker is disclosed and quantified, which is important for assessing voting influence and any potential coordinated action.
