On March 9, 2026, the Issuer entered into a subscription agreement (the "Subscription Agreement") with a number of institutional accredited investors, including NEA 17, pursuant to which the Issuer agreed to issue and sell to the investors in a private placement (the "2026 Private Placement") (i) an aggregate of 4,501,928 shares of Common Stock and (ii) pre-funded warrants to purchase an aggregate of 3,148,836 shares of Common Stock (the "Pre-Funded Warrants"). The 2026 Private Placement closed on March 10, 2026. In connection with the closing, NEA 17 purchased (i) 207,100 shares of Common Stock at a purchase price of $11.11 per share and (ii) Pre-Funded Warrants to purchase 242,945 shares of Common Stock (the "NEA 17 Pre-Funded Warrants") at a purchase price of $11.109 per Pre-Funded Warrant with an exercise price of $0.001 per underlying share of Common Stock. The exercise price of each Pre-Funded Warrant is subject to customary adjustments. The Pre-Funded Warrants are exercisable at the option of the holder at any time after their issuance; provided that the Pre-Funded Warrants carry a limitation on exercise if such exercise would cause the number of shares of Common Stock owned by the holder (together with its affiliates and certain other related parties) to exceed 9.99% of the total number of shares of Common Stock, which percentage may be increased or decreased at the option of the holder upon 61 days' prior notice, not to exceed 19.99% (the "Beneficial Ownership Limitation").

The working capital of NEA 17 is the source of the funds for the purchase of the NEA 17 Shares. No part of the purchase price of the NEA 17 Shares is represented by funds or other consideration borrowed or otherwise obtained for the purpose of acquiring, holding, trading or voting the NEA 17 Shares. The foregoing description of the Subscription Agreement and the terms and conditions of the securities issued thereunder is qualified in its entirety by reference to the full text of the Subscription Agreement, a copy of which is attached as Exhibit 10.1 to the Issuer's Form 8-K filed with the Securities and Exchange Commission (the "SEC") on March 9, 2026 (the "Form 8-K") and incorporated herein by reference.
