1. Nature of Business

Inhibikase Therapeutics, Inc. is a clinical-stage pharmaceutical company developing therapeutics to modify the course of cardiopulmonary diseases, namely, Pulmonary Arterial Hypertension (“PAH”), in which aberrant signaling through type III receptor tyrosine kinases, including platelet derived growth factor receptors and a stem cell factor receptor, known as “c-Kit”, has been implicated. The Company's lead product candidate is IKT-001, a prodrug of imatinib mesylate (“imatinib”), for PAH which is an orphan indication. Imatinib was first approved in the United States in 2001 for various cancers and blood disorders and, following more than 20 years of clinical use, has a well-characterized safety profile with the first reported use of imatinib in PAH occurring in 2005. PAH is a progressive, life-threatening disease characterized by pulmonary vascular remodeling and elevated pulmonary vascular resistance that affects approximately 50,000 Americans. The Company has completed a non-human primate safety study and a bioequivalence clinical study in healthy volunteers to determine the doses of IKT-001 that are equivalent to imatinib. Our Phase 3 clinical study, named IMPROVE-PAH (IKT-001 for Measuring Pulmonary Vascular Resistance and Outcome Variables in a Phase 3 Evaluation of PAH), has been initiated with the activation of a small number of sites and the recent commencement of patient pre-screening activities at those sites.

Liquidity

As of December 31, 2025, the Company had cash, cash equivalents and marketable securities of $178.8 million.

The Company has incurred recurring losses and at December 31, 2025, had an accumulated deficit of $142.7 million.

To date, the Company has funded its operations primarily through public offerings of its common stock, private placements of its common stock (and pre-funded warrants) and sales of common stock through at-the-market (“ATM”) offerings. In December 2020, June 2021, January 2023, May 2024, October 2024 and November 2025, the Company raised approximately $14.6 million, $41.1 million, $8.5 million, $3.2 million, $99.6 million and $107.6 million, respectively, in net proceeds and $0.5 million in net ATM proceeds in 2024.

The Company is subject to a variety of risks similar to other early-stage life science companies including, but not limited to, the successful development, regulatory approval, and market acceptance of the Company’s product candidates, development by its competitors of new technological innovations, protection of proprietary technology, and raising additional working capital. The Company has incurred significant research and development expenses, general and administrative expenses related to its product candidate programs and negative cash flows from operations. The Company anticipates costs and expenses to increase in the future as the Company continues to develop and pursue regulatory approval of IKT-001.

The Company may seek to fund its operations through additional public equity, private equity, or debt financings, as well as other sources. However, the Company may be unable to raise additional working capital, or if it is able to raise additional capital, it may be unable to do so on commercially favorable terms or in a timely fashion (see Note 11). In addition, potential proceeds from the exercise of the Series A-1 Warrants or the Series B-1 Warrants may not be available to the Company in a timely fashion, or at all. The Company’s failure to raise sufficient or timely capital or enter into such other arrangements would have a negative impact on the Company’s business, financial viability, results of operations and financial condition and the Company’s ability to continue to develop its product candidates.

The Company estimates that its cash and cash equivalents and marketable securities at December 31, 2025 is sufficient to fund its normal operations for at least the next twelve months from the date of issuance of these consolidated financial statements.

The accompanying consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and satisfaction of liabilities in the ordinary course of business. The consolidated financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of the uncertainties described above.
