Note 7. Revenue from Contracts with Customers

The Company’s net sales are generated primarily from sales of iDose TR, its iStent family of products, Epioxa, Photrexa and associated drug formulations, and the proprietary bioactivation systems. The Company’s customers are primarily comprised of ambulatory surgery centers, hospitals and physician private practices, with third party distributors being used in certain international locations where the Company currently does not have a direct commercial presence.

The Company concluded that one performance obligation exists for the majority of its contracts with customers, which is to deliver products in accordance with the Company’s normal delivery times. Revenue is recognized when this performance obligation is satisfied, which is the point in time when the Company considers control of a product to have transferred to the customer. Revenue recognized reflects the consideration to which the Company expects to be entitled in exchange for those products or services.

Revenue is recognized at an amount that reflects the consideration the Company expects to be entitled to in exchange for goods or services, and substantially all of the Company’s net sales for the three and six months ended June 30, 2026 and June 30, 2025 are considered revenue from contracts with customers.

Disaggregation of Revenue

Contract Balances

Contract Assets

Amounts are recorded as accounts receivable when the Company’s right to consideration becomes unconditional. Payment terms on invoiced amounts are typically between 30 – 60 days for glaucoma and corneal health products, though extended payment terms have been offered as part of the iDose TR and Epioxa commercial launches. However, the Company does not consider any significant financing components in customer contracts given the expected time between transfer of the promised products and the payment of the associated consideration is less than one year. As of June 30, 2026 and December 31, 2025, substantially all amounts included in accounts receivable, net on the condensed consolidated balance sheets are related to contracts with customers.

Aside from the aforementioned contract assets, the Company does not have any contract assets given that the Company does not have any unbilled receivables and sales commissions on products are expensed within selling, general and administrative expenses within the condensed consolidated statements of operations when incurred as any incremental cost of obtaining contracts with customers would have an amortization period of less than one year.

Contract Liabilities

Contract liabilities reflect consideration received from customers’ purchases allocated to the Company’s future performance obligations.

The Company has a performance obligation to issue a volume-based rebate to customers who may be eligible for such rebate at the conclusion of their contract term. This performance obligation is transferred over time and the Company’s method of measuring progress is the output method, whereby the progress is measured by the estimated rebate earned to date over the total rebate estimated to be earned over the contract period.

Certain sales of the Company’s pharmaceutical products are subject to rebates under the Medicaid Drug Rebate Program (MDRP). The rebate accrual calculation requires management to estimate the volume of net sales that will be subject to these rebates. There can be significant time-lag in receiving rebate notices from each state (generally, several months or longer after a sale is recognized). Estimated MDRP rebates are recorded as a reduction of revenue in the period the related sale is recognized.

The Company’s total accrued volume-based rebates and MDRP allowances are included in accrued liabilities on the condensed consolidated balance sheets. A roll forward of activity for the six months ended June 30, 2026 is as follows:

Additionally, the Company has performance obligations related to voluntary patient assistance programs to provide financial assistance to qualified patients. These performance obligations are expected to be recognized when the customer or patient elects to utilize the discount, which is generally within one year. The impact of these programs on revenue were not material for the periods presented.

During the three and six months ended June 30, 2026 and June 30, 2025, the Company did not recognize any revenue related to material changes in transaction prices regarding its contracts with customers and did not recognize any material changes in revenue related to amounts included in contract liabilities at the beginning of the period.

The Company’s net sales within a fiscal year may be impacted seasonally, as demand for U.S. ophthalmic procedures is typically softer in the first quarter and stronger in the fourth quarter of a given year.
