Changes in Registrant’s Certifying Accountant.

(a) Resignation of Previous Independent Registered Public Accounting Firm

On October 15, 2025, the Audit Committee (the “ Committee”) of the Board of Directors of Solana Corporation (formerly known as Helius Medical Technologies, Inc.) (the “ Company”) received the resignation of Baker Tilly US, LLP (“ Baker Tilly”) as the Company’s independent registered public accounting firm, effective immediately. The Committee accepted Baker Tilly’s resignation.

The reports of Baker Tilly on the Company’s consolidated financial statements for each of the two most recent fiscal years ended December 31, 2024 and 2023 did not contain an adverse opinion or disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope, or accounting principles, except that such reports contained an explanatory paragraph expressing substantial doubt as to the Company’s ability to continue as a going concern.

During the Company’s two most recent fiscal years ended December 31, 2024 and 2023 and the subsequent interim period through October 15, 2025, there were (a) no “disagreements” (as that term is described in Item 304(a)(1)(iv) of Regulation S-K promulgated under the Securities Exchange Act of 1934, as amended (“ Regulation S-K”) and the related instructions) with Baker Tilly on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Baker Tilly, would have caused it to make reference to the subject matter of the disagreements in connection with its reports and (b) no “reportable events,” as defined in Item 304(a)(1)(v) of Regulation S-K and the related instructions.

The Company provided Baker Tilly with a copy of the foregoing disclosures and requested that Baker Tilly furnish a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the statements made herein, as specified by Item 304(a)(3) of Regulation S-K. A copy of Baker Tilly’s letter, dated October 16, 2025, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
