The increase was primarily driven by increased investment in clinical program and employee-related spend. Non-GAAP costs and expenses for the three months ended September 30, 2026, were $19.1 million, an increase of $4.5 million compared to $14.6 million in the prior year period, driven by increased clinical program and employee-related spend.

GAAP net loss for the three months ended September 30, 2026 was ($23.1) million compared to ($19.4) million for the three months ended September 30, 2025. Non-GAAP net loss for the three months ended September 30, 2026, was ($17.5) million compared to ($13.5) million for the three months ended September 30, 2025.

Cash, cash equivalents, and marketable securities totaled $189.2 million as of September 30, 2026, compared to $101.6 million in cash and cash equivalents as of June 30, 2026. The sequential increase of $87.6 million reflects net proceeds raised under the Company’s ATM programs. Cash used in operating activities in the third quarter of 2026 totaled $15.3 million, compared to $13.0 million in the same period of the prior year and $18.7 million in the second quarter of 2026.

The Company raised $95.8 million in net proceeds through its ATM programs during the third quarter, bringing the total since May to more than $150 million, representing under 6% dilution. Approximately $64 million of ATM capacity remains available.

Non-GAAP Financial Measures

In this press release, in order to supplement the Company’s condensed consolidated financial statements presented in accordance with Generally Accepted Accounting Principles, or GAAP, management has disclosed certain non-GAAP financial measures for the statement of operations. The Company believes that an evaluation of its ongoing operations (and comparisons of its current operations with historical and future operations) would be difficult if the disclosure of its financial results were limited to financial measures prepared in accordance with GAAP. As a result, the Company is disclosing certain non-GAAP results in order to supplement investors’ and other readers’ understanding and assessment of the Company’s financial performance. Company management uses these measurements as aids in monitoring the Company’s ongoing financial performance from quarter to quarter, and year to year, on a regular basis and for financial and operational decision-making. Non-GAAP adjustments include stock-based compensation, depreciation and amortization, and a legal settlement. From time to time in the future, there may be other items that the Company may exclude if the Company believes that doing so is consistent with the goal of providing useful information to management and investors. The Company has provided a reconciliation of each non-GAAP financial measure used in this earnings release to the most directly comparable GAAP financial measure. Investors are cautioned that there are a number of limitations associated with the use of non-GAAP financial measures as analytical tools. Investors are encouraged to review these reconciliations, and not to rely on any single financial measure to evaluate the Company’s business.

Non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies, which could reduce the usefulness of the Company’s non-GAAP financial measures as tools for comparison. Investors and other readers are encouraged to review the related GAAP financial measures and the reconciliation of non-GAAP measures to their most directly comparable GAAP measures set forth below and should consider non-GAAP measures only as a supplement to, not as a substitute for or as a superior measure to, measures of financial performance prepared in accordance with GAAP. Non-GAAP financial measures in this earnings release exclude non-cash expenses for stock-based compensation, depreciation and amortization and legal settlement expenses.
