The Company expects that its existing cash, cash equivalents and marketable securities at September 30, 2026 will be sufficient to fund its current and planned operating expenses and capital expenditures for at least 12 months from the filing date of this Quarterly Report on Form 10-Q. Beyond that date, the Company may need to raise additional capital through a combination of equity offerings, debt financings, collaborations, strategic alliances and licensing arrangements to achieveits longer-term business objectives.
