Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Otis Worldwide Corporation and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of operations, of comprehensive income, of changes in 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 accompanying index (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 the accompanying Management’s Report on Internal Control over Financial Reporting. 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 matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (i) relates 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 matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition - Estimated Costs at Completion for New Equipment and Modernization Contracts

As described in Notes 2 and 21 to the consolidated financial statements, the Company recognized $5.0 billion and $1.9 billion of revenue from new equipment and modernization contracts, respectively, for the year ended December 31, 2025. For new equipment and modernization contracts, equipment and installation are typically procured in a single contract providing the customer with a complete installed elevator or escalator unit. The combination of equipment and installation promises are typically a single performance obligation. For these performance obligations, revenue is recognized over time using costs incurred to date relative to total estimated costs at completion to measure progress. As disclosed by management, contract costs are usually incurred over a period of time, which can be several years, and the estimation of these costs requires management’s judgment. The long-term nature of the contracts, the complexity of the products and the scale of the projects can affect management’s ability to estimate costs precisely. In developing the cost estimates, management utilizes a combination of the historical costs and expected costs considering current circumstances. Management reviews cost estimates for modification on significant new equipment and modernization contracts on a quarterly basis and when circumstances change and, for others, no less frequently than annually or when circumstances change and warrant a modification to a previous estimate. Management records changes in contract estimates using the cumulative catch-up method and reviews changes in contract estimates for their impact on net sales or operating profit in the consolidated financial statements. Contract costs included in the calculation are comprised of labor, materials, subcontractors’ costs or other direct costs and indirect costs, which include indirect labor costs.

The principal considerations for our determination that performing procedures relating to revenue recognition - estimated costs at completion for new equipment and modernization contracts is a critical audit matter are the significant judgment by management to determine the estimated costs at contract completion, which in turn led to significant auditor judgment, subjectivity and effort in performing procedures and evaluating audit evidence related to the estimated expected labor and indirect labor costs used in the development of estimated costs at contract completion.

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 revenue recognition process, including controls over the determination of the estimated costs at contract completion and development of the significant assumptions related to the estimated expected labor and indirect labor costs. These procedures also included, among others, evaluating and testing management’s process for developing and modifying estimated costs at contract completion for a sample of contracts, which included evaluating the reasonableness of significant assumptions related to the estimated expected labor and indirect labor costs considered by management specific to each contract. Evaluating the reasonableness of the estimated expected labor and indirect labor costs involved assessing management’s ability to reasonably estimate costs at completion by (i) testing costs incurred to date and obtaining a sample of executed contracts and related change orders, (ii) performing a comparison of the margin, driven by the estimated and actual costs incurred, to that of similar completed equipment contracts, and (iii) evaluating the timely identification of circumstances that may warrant a modification to estimated total cost to complete.
