Inventories are valued under a standard costing methodology on a first-in, first-out basis and are stated at the lower of cost or net realizable value. The Company capitalizes inventory costs related to products to be sold in the ordinary course of business. The Company makes a determination of capitalizing inventory costs for a product based on, among other factors, status of

regulatory approval, information regarding safety, efficacy and expectations relating to commercial sales and recoverability of costs. Capitalized costs of inventories for LUPKYNIS (voclosporin) mainly include third party manufacturing costs, transportation, storage, insurance, and allocated internal labor. Due to the nature of the Company's supply chain process, inventory that is owned by the Company, is physically stored at third-party warehouses, logistics providers, and contract manufacturers.

The Company assesses recoverability of inventory each reporting period to determine if any write-down to net realizable value is necessary. As of September 30, 2024, and December 31, 2023, Aurinia recorded reserves of finished goods inventories of nil and $0.8 million, respectively, which were primarily related to potential inventory obsolescence.
