Note 8—Revolving Credit Facility

Parkview Credit Facility

On April 21, 2026, the Company entered into a Loan Agreement (the “Loan Agreement”) with Parkview, an affiliate of K&V Investment LLC (“K&V Investment One”) (a holder of more than 5% of the Company’s fully diluted capital stock and an entity owned by Vijay Patel), pursuant to which Parkview agreed to extend a $50 million revolving credit facility to the Company maturing on April 21, 2031. Borrowings under the facility bear interest at 12% per annum (plus an additional 6% during any event of default), payable monthly in arrears, and are secured by substantially all assets of the Company and its subsidiaries. The Company is obligated

to repay principal equal to 75% of net profits from pharmaceutical product sales from the prior quarter if it achieves net profits for two consecutive fiscal quarters.

Each borrowing shall be an amount not to exceed the greater of (i) $1.7 million and (ii) the monthly budgeted expense amount in the Company’s expense budget (which will be subject to agreement of the Company and Parkview) for the immediately subsequent month. There have been $3.6 million proceeds received under this Loan Agreement through June 30, 2026.

In connection with the Loan Agreement, the Company and Parkview entered into: (i) a Fee Letter pursuant to which the Company agreed to pay a one-time commitment fee of $5 million, which the Company elected to pay by issuing 1,878,287 shares of Company common stock to Parkview (subject to stockholder approval) and an annual facility fee of 1.5% of the total commitment beginning on the first anniversary; (ii) a Royalty Agreement granting Parkview an annual royalty in the low to mid-single digits on Net Sales (as defined therein) of products based on the Company’s IFx-2.0 intellectual property, up to $450 million in Net Sales per year, continuing through the last-to-expire patent covering IFx-2.0; and (iii) two Warrant Amendment Agreements extending to April 21, 2031, the exercise period for an aggregate of 4,364,873 warrants to purchase common stock held by K&V Investment One (3,049,432 warrants at $3.69 per share and 1,315,441 warrants at $5.70 per share).

The Loan Agreement contains certain embedded features that were identified and evaluated as not material to the condensed consolidated financial statements. In particular, due to inherent uncertainties involved in bringing a product through regulatory approval, the Royalty Agreement has nominal value and therefore none of the debt proceeds have been allocated to this feature.
