Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Adeia Inc. and its subsidiaries (the “Company”) as of December 31, 2025 and 2024, and the related consolidated statements of income, of comprehensive income, of equity and of cash flows for each of the three years in the period ended December 31, 2025, including the related notes and financial statement schedule listed in the index appearing under Item 15(a)(2) (collectively referred to as the “consolidated financial statements”). We also have audited the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025 in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the COSO.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in Management’s Report on Internal Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on the Company’s consolidated financial statements and on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that (i) relate to accounts or disclosures that are material to the consolidated financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Revenue Recognition – Determination of Standalone Selling Price of Performance Obligations in a Certain Long-Term License Contract

As described in Note 4 to the consolidated financial statements, at times, the Company enters into long-term license contracts with more than one performance obligation, which may include releases from past patent infringement claims or one or more prospective licenses. In these arrangements, management allocates the transaction price between releases for past patent infringement claims and prospective licenses based on their relative standalone selling prices. Determination of standalone selling price requires significant management judgment. In determining the standalone selling price of each performance obligation, management considers such factors as the customer’s revenues, the number of past and projected future subscribers, units shipped, and units manufactured, as well as the per-subscriber or per-unit licensing rates the Company generally receives from licensees of comparable sizes in comparable markets and geographies. The Company recorded total revenue of $443 million for the year ended December 31, 2025, of which a portion relates to a certain long-term license contract with multiple performance obligations.

The principal considerations for our determination that performing procedures relating to the determination of standalone selling price of performance obligations in a certain long-term license contract is a critical audit matter are (i) the significant judgment by management when determining the standalone selling price of the performance obligations and (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating management’s determination of standalone selling price.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the licensing revenue recognition process, including controls over the determination of standalone selling price of performance obligations in certain long-term license contracts. These procedures also included, among others, (i) reading the executed contract to understand the terms and conditions, (ii) evaluating management’s identification of the performance obligations, (iii) testing management’s process for determining the value of standalone selling prices of identified performance obligations, (iv) evaluating the appropriateness of the overall methodology used by management to develop the standalone selling price, and (v) evaluating, as applicable, the reasonableness of the factors used in management’s determination of standalone selling price. Evaluating the reasonableness of the factors used by management included, as applicable, assessing whether they were consistent with (i) the Company’s relevant historical transactions, (ii) external market data, and (iii) other information obtained in the audit. Testing the determination of standalone selling price also involved testing the completeness and accuracy of the data utilized by management.

Valuation of Noncash Consideration Received in a Certain Contract with a Customer

As described in Notes 4 and 7 to the consolidated financial statements, in certain contracts with customers, the Company receives noncash consideration in the form of patents, and the fair value of those assets is included in the transaction price for revenue recognition purposes. For noncash consideration received in the year ended December 31, 2025, management determined the fair value at contract inception using an analysis of comparable market transactions (the market approach). Estimating the fair value of the patents requires significant judgments and assumptions, including the selection and weighting of comparable market transactions. As disclosed by management, revenue recognized from noncash consideration represented 5.8% of total revenue recognized of $443 million for the year ended December 31, 2025, of which a significant portion of the revenue recognized from noncash consideration received related to a certain contract with a customer.

The principal considerations for our determination that performing procedures relating to the valuation of noncash consideration received in a certain contract with a customer is a critical audit matter are (i) the significant judgment by management when developing the fair value estimate of the noncash consideration; (ii) a high degree of auditor judgment, subjectivity and effort in performing procedures and evaluating management’s significant assumptions used in the market approach related to the selection and weighting of comparable market transactions; and (iii) the audit effort involved the use of professionals with specialized skill and knowledge.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. These procedures included testing the effectiveness of controls relating to the licensing revenue recognition process, including controls over the valuation of noncash consideration received from customers. These procedures also included, among others (i) reading the executed contract to understand the terms and conditions, (ii) testing management’s process for developing the fair value estimate of the noncash consideration; (iii) evaluating the appropriateness of the market approach used by management; (iv) testing the completeness and accuracy of underlying data used in the market approach; and (v) evaluating the reasonableness of the significant assumptions used by management related to the selection and weighting of comparable market transactions. Professionals with specialized skill and knowledge were used to assist in evaluating (i) the appropriateness of the market approach and (ii) the reasonableness of the selection and weighting of comparable market transaction assumptions.
