The accompanying unaudited condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting only of normal recurring adjustments, necessary for a fair statement of the Company’s financial position, results of operations and cash flows for the periods presented. Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (the “FASB”).

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2025 included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025 (the “2025 10-K”). All intercompany balances and transactions have been eliminated in consolidation. The preparation of our interim consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed. We have made reasonable estimates and judgments of such items within our financial statements and there may be changes to those estimates in future periods.

During the three and six months ended June 30, 2026 and 2025, comprehensive income was equal to the net income amounts presented for the respective periods in the accompanying condensed consolidated statements of operations. Results for interim periods are not necessarily indicative of the results that may be expected for the full fiscal year.

The preparation of financial statements requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Significant estimates include estimates related to the Company’s effective tax rate.

Accounts receivable is reported at realizable value, net of allowances for customer credits and credit losses in the amount of $0.8 million and $0.3 million at June 30, 2026 and December 31, 2025, respectively. The Company extends credit to its customers based upon an evaluation of each customer’s financial condition and credit history. Evaluations of the financial condition, payment history and associated credit risk of customers are performed on an ongoing basis. Based on these evaluations, the Company has concluded that its credit risk is minimal. At June 30, 2026 and December 31, 2025, two customers accounted for an aggregate of approximately 81% and 87%, respectively, of the Company’s total accounts receivable.

Raw materials inventory consists of normal source plasma (“NSP”) and respiratory syncytial virus (“RSV”) high-titer plasma collected at the Company’s plasma collection facilities or purchased from third parties, along with various materials purchased from suppliers, used in the production of the Company’s products. Work-in-process and finished goods inventories (see Note 3) reflect the cost of raw materials as well as costs for direct and indirect labor, primarily salaries, wages and benefits for applicable employees, as well as an allocation of overhead costs related to the Boca Facility including utilities, property taxes, general repairs and maintenance, consumable supplies and depreciation.

Inventories, including plasma intended for resale and plasma intended for internal use in the Company’s manufacturing, commercialization or research and development activities, are carried at the lower of cost or net realizable value determined by the first-in, first-out method. For both the Company’s immune globulin products and plasma intended for resale and internal use, net realizable value is generally determined based upon the consideration the Company expects to receive when the inventory is sold, less costs to deliver the inventory to the recipient. The estimates for net realizable value of inventory are based on contractual terms or upon historical experience and certain other assumptions, and the Company believes that such assumptions are reasonable. Inventory is periodically reviewed to ensure that its carrying value does not exceed its net realizable value, and adjustments are recorded to write down such inventory, with a corresponding charge to cost of product revenue, when the carrying value or historical cost exceeds its estimated net realizable value. In addition, costs associated with the production of engineering lots that would not qualify as immediately available for commercial sale are charged to cost of product revenue and not capitalized into inventory.

Revenues are comprised of (i) revenues from the sale of the Company’s immunoglobulin products, ASCENIV, BIVIGAM and Nabi-HB, (ii) product revenues from the sale of human plasma collected by the Company’s Plasma Collection Centers business segment, (iii) contract manufacturing and laboratory services revenue, (iv) revenues from the sale of intermediate by-products and (v) license and other revenues primarily attributable to the out-licensing of ASCENIV to Biotest AG (“Biotest”) in 2012 to market and sell this product in Europe and certain countries in Northern Africa and the Middle East. Biotest has provided the Company with certain services and financial payments in accordance with the related Biotest license agreement and is obligated to pay the Company certain amounts in the future if certain milestones are achieved. Deferred revenue is amortized into income over the term of the Biotest license, representing a period of approximately 22 years.

Product revenue is recognized when the customer is deemed to have control over the product and the performance obligation is satisfied. Control is determined based on when the product is shipped or delivered and title passes to the customer. Revenue is recorded in an amount that reflects the consideration the Company expects to receive in exchange. Revenue from the sale of the Company’s immunoglobulin products is recognized when the product reaches the customer’s destination, and is recorded net of estimated rebates, wholesaler distribution and related fees, customer incentives, including prompt pay discounts, wholesaler chargebacks, group purchasing organization fees and reimbursements for patient assistance. These estimates are based on contractual arrangements, historical experience and certain other assumptions, and while the Company believes that such estimates are reasonable, they are subject to change based on future developments and other factors.

Product revenues from the sale of human plasma collected at the Company’s plasma collection centers are recognized at the time control of the product has been transferred to the customer and the performance obligation is satisfied, which generally occurs at the time of shipment from one of the Company’s plasma collection facilities or from a third-party warehouse that is utilized by the Company. Product revenues are recognized at the time of delivery if the Company retains control of the product during shipment.

For the three and six months ended June 30, 2026, three customers represented an aggregate of approximately 76% and 79%, respectively, of the Company’s consolidated revenues. For the three and six months ended June 30, 2025, three customers represented an aggregate of approximately 88% and 81%, respectively, of the Company’s consolidated revenues.

Cost of product revenue includes costs associated with the manufacture of the Company’s FDA approved products and intermediates and for the collection of human source plasma, as well as expenses related to conformance batch production, process development and scientific and technical operations when these operations are attributable to marketed products. When the activities of these operations are attributable to new products in development, the expenses are classified as research and development expenses.

The carrying amounts of certain of the Company’s financial instruments, including cash and cash equivalents, accounts receivable and accounts payable are shown at cost, which approximates fair value due to the short-term nature of these instruments. The debt outstanding under the Company’s senior notes payable (see Note 7) also approximates fair value, based on a Level 3 classification under the fair value hierarchy, due to the variable interest rate on this debt.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements (“ASU 2025-11”), which clarifies the guidance in Topic 270 to improve the consistency of interim financial reporting. The ASU provides a comprehensive list of required interim disclosures and introduces a disclosure principle requiring entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for fiscal years beginning after December 15, 2027, including interim periods within those fiscal years, with early adoption permitted. The Company is currently evaluating the impact of adopting ASU 2025-11.

In November 2024, FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses (“ASU 2024-03”), requiring public entities to disclose additional information about specific expense categories in the notes to the financial statements on an interim and annual basis. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027, with early adoption permitted. The adoption of ASU 2024-03 will result in changes to the presentation of the Company’s financial statements, the impact of which is currently being evaluated.
