Securities Purchase Agreements

On September 15, 2025, Helius Medical Technologies, Inc. (the “Company”) entered into securities purchase agreements (the “Cash Securities Purchase Agreements”) with certain accredited investors (the “Cash Purchasers”) pursuant to which the Company agreed to sell and issue to the Cash Purchasers in a private placement offering (the “Cash Offering”) an aggregate offering of (i) either shares (the “Cash Shares”) of Class A common stock of the Company, par value $0.001 per share (the “Common Stock”) at an offering price of $6.881 per Cash Share (the “Per Share Cash Purchase Price”); and/or pre-funded warrants (the “Cash Pre-Funded Warrants”) to purchase shares of the Common Stock (the “Cash Pre-Funded Warrant Shares”) at an offering price of the Per Share Cash Purchase Price less $0.001 per Cash Pre-Funded Warrant, and (ii) stapled warrants (the “Cash Stapled Warrants” and, together with the Cash Shares and the Cash Pre-Funded Warrants, the “Cash Securities”) to purchase shares of the Common Stock (the “Cash Stapled Warrant Shares”) at an exercise price of $10.134 per Cash Stapled Warrant. In the Cash Offering, the Cash Purchasers will tender any of U.S. dollars, USDC or USDT (or a combination thereof) to the Company as consideration for the Cash Shares, Cash Stapled Warrants and Cash Pre-Funded Warrants.

Each of the Cash Pre-Funded Warrants is exercisable for one share of Common Stock at the remaining exercise price of $0.001 per Cash Pre-Funded Warrant Share, immediately exercisable by the registered holder, and may be exercised at any time following registration until all of the Cash Pre-Funded Warrants issued in the Cash Offering are exercised in full. Each Purchaser’s ability to exercise its Cash Pre-Funded Warrants in exchange for shares of Common Stock is subject to certain beneficial ownership limitations set forth therein. Each of the Cash Stapled Warrants is exercisable for one share of Common Stock at the exercise price of $10.134 per Cash Stapled Warrant Share, immediately exercisable upon registration, and may be exercised at any time following registration until the earlier of (i) 36 months after the closing of the Cash Offering or (ii) all of the Cash Stapled Warrants issued in the Cash Offering are exercised in full. If the daily volume-weighted average price of the Common Stock is above 200% of the share offering price during any 20 trading days in a 30-trading day period (the “Measurement Period”) and for each of the last five (5) consecutive trading days during the Measurement Period, at the election of the Company, the Company can require the Cash Stapled Warrants be exercised.

Additionally, on September 15, 2025, the Company entered into securities purchase agreements (the “Cryptocurrency Securities Purchase Agreements,” and together with the Cash Securities Purchase Agreements, the “Securities Purchase Agreements”) with certain accredited investors (the “Cryptocurrency Purchasers,” and together with the Cash Purchasers, the “Purchasers”) pursuant to which the Company agreed to sell and issue to the Cryptocurrency Purchasers in a private placement (the “Cryptocurrency Offering,” and together with the Cash Offering, the “Offerings”) (i) pre-funded warrants (“Cryptocurrency Pre-Funded Warrants” and, together with the Cash Pre-Funded Warrants, the “Pre-Funded Warrants”) to purchase shares of Common Stock (“Cryptocurrency Pre-Funded Warrant Shares” and, together with the Cash Pre-Funded Warrant Shares, the “Pre-Funded Warrant Shares”) at an offering price of $6.881 less $0.001 and (ii) stapled warrants (the “Cryptocurrency Stapled Warrants,” and together with the Cash Stapled Warrants, the “Stapled Warrants”) to purchase shares of Common Stock (the “Cryptocurrency Stapled Warrant Shares,” and together with the Cash Stapled Warrant Shares, the “Stapled Warrant Shares”) at an exercise price of $10.134 per Cryptocurrency Stapled Warrant. In the Cryptocurrency Offering, the Cryptocurrency Purchasers will tender either Unlocked SOL tokens or Locked SOL tokens to the Company as consideration for the Cryptocurrency Pre-Funded Warrants and the Cryptocurrency Stapled Warrants.

The exercise of the Cryptocurrency Pre-Funded Warrants and Cryptocurrency Stapled Warrants into Cryptocurrency Pre-Funded Warrant Shares and Cryptocurrency Stapled Warrant Shares, respectively, is subject to stockholder approval (“Stockholder Approval”) and such warrants will not be exercisable for Common Stock until such Shareholder Approval is received. Pursuant to the Cryptocurrency Securities Purchase Agreement, the Company will hold a special meeting of stockholders to obtain Stockholder Approval as soon as practicable after the closing date of the Offerings.

Each of the Cryptocurrency Pre-Funded Warrants is exercisable for one share of Common Stock at the exercise price of $0.001 per Cryptocurrency Pre-Funded Warrant Share, immediately exercisable following Stockholder Approval (the “Effective Date”), and may be exercised at any time on or after the Effective Date until all of the Cryptocurrency Pre-Funded Warrants issued in the Offerings are exercised in full. Each Cryptocurrency Purchaser’s ability to exercise its Cryptocurrency Pre-Funded Warrants in exchange for shares of Common Stock is subject to certain beneficial ownership limitations set forth therein. Each of the Cryptocurrency Stapled Warrants is exercisable for one share of Common Stock at the exercise price of $10.134 per Cryptocurrency Stapled Warrant Share, immediately exercisable on or after the Effective Date, and may be exercised at any time on or after the Effective Date until the earlier of (i) 36 months after the closing of the Cryptocurrency Offering or (ii) all of the Cryptocurrency Stapled Warrants issued in the Cryptocurrency Offering are exercised in full. If the daily volume-weighted average price of the Common Stock is above 200% of the share offering price during the Measurement Period and for each of the last five (5) consecutive trading days during the Measurement Period, and subject to election and notice by the Company, the Company can require the Cryptocurrency Stapled Warrants be exercised.

The Common Stock, the Pre-Funded Warrants, the Pre-Funded Warrant Shares, the Stapled Warrants, and the Stapled Warrant Shares are being offered in reliance upon the exemption from the registration requirement of the Securities Act of 1933, as amended (the “Securities Act”), pursuant to Section 4(a)(2) thereof and/or Rule 506(b) of Regulation D promulgated thereunder, and applicable state securities laws. The issuance of the Common Stock, the Pre-Funded Warrants, the Pre-Funded Warrant Shares, the Stapled Warrants, and the Stapled Warrant Shares have not been registered under the Securities Act and such securities may not be offered or sold in the United States absent registration or an exemption from registration under the Securities Act and any applicable state securities laws.

The closing of the Offerings is expected to occur on or about September 18, 2025, subject to the satisfaction of customary closing conditions. The Company intends to use the net proceeds from the Offerings to fund the acquisition of SOL, the native cryptocurrency of the Solana Foundation blockchain, through open market purchases only and the establishment of the Company’s Solana treasury operations, as well as for working capital, general corporate purposes and to pay all transaction fees and expenses related thereto. The Company will not use the net proceeds from the Offerings: (a) for the redemption of any outstanding Common Stock or Common Stock equivalents of the Company, (b) for the settlement of any outstanding litigation or (c) in violation of the Foreign Corrupt Practices Act of 1977, as amended or the Office of Foreign Assets Control of the U.S. Treasury Department regulations.

The Securities Purchase Agreements contain customary representations, warranties and agreements by the Company, customary conditions to closing, indemnification obligations of the Company, other obligations of the parties and termination provisions. Additionally, pursuant to the Purchase Agreements, the Company agreed to use commercially reasonable efforts to file a registration statement with the U.S. Securities and Exchange Commission, within 30 days of the closing of the Offering registering the resale of the Common Stock sold in the Offering, the Pre-Funded Warrants, the Pre-Funded Warrant Shares, the Stapled Warrants, the Stapled Warrant Shares, and certain securities to be issued to the Company’s strategic advisor.

Each of the Cash Purchasers have agreed to not to sell, transfer, pledge, hedge, or otherwise dispose of any Cash Securities until the resale registration statement is declared effective (the “Effectiveness Date”), and with respect to 50% of the Cash Securities, until 30 calendar days following the Effectiveness Date (the “PIPE Lock-Up Period”), except with the Company’s prior written consent and subject to certain customary exceptions. Each of the Cryptocurrency Purchasers have agreed to not to sell, transfer, pledge, hedge, or otherwise dispose of any Cryptocurrency Securities during the PIPE Lock-Up Period, except with the Company’s prior written consent and subject to certain customary exceptions.
