Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of PC Connection, Inc. and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of income, comprehensive income, changes in shareholder’s equity, and cash flows, for each of the three years in the period ended December 31, 2024, and the related notes and the schedule listed in the Index at Item 15 (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2024, based on criteria established inInternal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 24, 2025, expressed an unqualified opinion on the Company’s internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the 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 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the 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 — Refer to Note 2 to the financial statements

Critical Audit Matter Description

As described in Note 2 to the consolidated financial statements, the Company recognizes revenue when control is transferred to the customer. The amount of revenue recognized by the Company is dependent upon whether the Company is the principal in the transaction whereby revenue is recorded on a gross basis or the agent whereby the revenue is reported net. The Company applies judgment to determine if the Company is the principal or the agent in the transaction. The Company has determined that in general they are the principal in providing hardware products and on-premise software products, and that they are the agent in providing cloud-based software products and maintenance products. This determination is based on certain factors such as whether the Company controls the goods or services before they are transferred to the customer, whether the Company is primarily responsible for fulfilling the promise to provide the good or service, the inventory risk associated with the transaction, and the discretion in establishing price for good or service.

Given these factors and due to the volume of transactions, the related audit effort in evaluating management's judgments in determining principal versus agent determination for these customer agreements was extensive and required a high degree of auditor judgment.
