Previous report
Proposed legislation in the U.S. Congress, including changes in U.S. tax law, may adversely impact us and the value of our shares of Common Stock, Pre-Funded Warrants, Warrants and Warrant Shares.
Previous report
Changes to U.S. tax laws (which changes may have retroactive application) could adversely affect us or holders of our shares of Common Stock, Pre-Funded Warrants, Warrants and Warrant Shares. In recent years, many changes to U.S. federal income tax laws have been proposed and made, and additional changes to U.S. federal income tax laws are likely to continue to occur in the future.
Previous report
The U.S. Congress is currently considering numerous items of legislation which may be enacted prospectively or with retroactive effect, which legislation could adversely impact our financial performance and the value of our shares of Common Stock, Pre-Funded Warrants, Warrants and Warrant Shares. Additionally, states in which we operate or own assets may impose new or increased taxes. If enacted, most of the proposals would be effective for the current or later years. The proposed legislation remains subject to change, and its impact on us and purchasers of our shares of Common Stock, Pre-Funded Warrants, Warrants and Warrant Shares is uncertain
Previous report
On May 22, 2025, the U.S. House of Representatives passed a tax bill, which the Senate Finance Committee subsequently modified and released on June 16, 2025, that, if enacted into law in its current form, may affect the U.S. federal income tax considerations applicable to certain non-U.S. investors in our shares of Common Stock, Pre-Funded Warrants, Warrants and Warrant Shares. In particular, the bill proposes to add new Section 899 to the Code, which could significantly increase the aggregate tax liability of certain non-U.S. investors with respect to their investment in our shares of Common Stock, Pre-Funded Warrants, Warrants and Warrant Shares. The likelihood of the bill or other similar legislation being enacted is uncertain, and the provisions of the bill or other similar legislation may change prior to enactment. Non-U.S. investors are urged to consult their tax advisors regarding the potential application of proposed Section 899 of the Code with respect to their investment in our shares of Common Stock, Pre-Funded Warrants, Warrants and Warrant Shares.

The Panel’s decision provided us with an exception until June 22, 2025, to demonstrate compliance with the Minimum Stockholders’ Equity Requirement (as defined below) for continued listing set forth in Nasdaq Listing Rule 5550(b). The Panel reviewed our compliance plan, which includes the continuation of fundraising efforts that began in 2024 and strategies for achieving long-term compliance with the Stockholders’ Equity Requirement.

Previous wording
Developing medical device products, including conducting preclinical studies and clinical trials, is expensive. We expect our research and development expenses to increase in connection with our ongoing activities, particularly as we advance our clinical programs. As of September 30, 2025, we have positive working capital of $10.8 million while we had negative working capital of $3.1 million on December 31, 2024, respectively. We currently do not have sufficient capital to support our operations and complete our planned regulatory approval process. We will need to secure additional capital to continue our operations, and such funding may not be available on acceptable terms, or at all.

Pursuant to Nasdaq Listing Rule 5815(d)(4)(B), we will be subject to a Mandatory Panel Monitor until July 1, 2026.
