At each reporting date, the Company performs an evaluation of impairment to determine if any unrealized losses are the result of credit losses. Impairment is assessed at the individual security level. Factors considered in determining whether a loss resulted from a credit loss or other factors include the Company’s intent and ability to hold the investment until the recovery of its amortized cost basis, the extent to which the fair value is less than the amortized cost basis, the length of time and extent to which fair value has been less than the cost basis, the financial condition of the issuer, any historical failure of the issuer to make scheduled interest or principal payments, any changes to the rating of the security by a rating agency, any adverse legal or regulatory events affecting the issuer or issuer’s industry, and any significant deterioration in economic conditions.

The credit-related portion of unrealized losses, and any subsequent improvements, are recorded in interest expense in the accompanying condensed consolidated statements of operations through an allowance for credit losses. Unrealized gains and losses that are not credit-related are included in accumulated other comprehensive loss. Unrealized losses on available-for-sale debt securities as of September 30, 2026 and December 31, 2025 were not significant and were primarily due to changes in interest rates, including market credit spreads, and not due to increased credit risks associated with specific securities. Further, the Company does not intend to sell these investments prior to maturity and it is not more likely than not that the Company will be required to sell these investments before recovery of their amortized cost basis. Accordingly, the Company did not record an allowance for credit losses with respect to these investments as of September 30, 2026 and December 31, 2025.

Accounts receivable, net increased as of September 30, 2026 compared to December 31, 2025 primarily due to an increased proportion of net sales from iDose TR and Epioxa during the first nine months of 2026 given iDose TR and Epioxa have extended payment terms and higher net sales price per unit than the Company’s other products. The Company’s allowance for credit losses represents management’s estimate of current expected credit losses related to customer receivables. Bad-debt write-offs charged during the three and nine months ended September 30, 2026 were not significant.

Additionally, one customer, the Company's specialty pharmacy, accounted for approximately 17% of net accounts receivable as of September 30, 2026. No single customer accounted for more than 10% of net accounts receivable as of December 31, 2025.
