To the Stockholders and Board of Directors of

Acorn Energy, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Acorn Energy, Inc. (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations, changes in equity (deficit), and cash flows for each of the two years in the period ended December 31, 2024, and the related notes (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 two years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

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 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 financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

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 Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate 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 matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Realizability of Deferred Tax Assets

Critical Audit Matter Description

As described in Note 10 of the financial statements, at December 31, 2024, the Company had deferred tax assets of $4.4 million (net of a $11.4 million valuation allowance). Deferred tax assets are reduced by a valuation allowance if, based upon the weight of all available evidence, it is more likely than not that some portion, or all, of the deferred tax assets will not be realized.

Auditing the Company’s analysis of the realizability of its deferred tax assets required complex auditor judgment because the amounts are material to the financial statements and the assessment process involves significant judgment related to the projections of future taxable income that may be affected by future market or economic conditions.

How the Critical Audit Matter Was Addressed in the Audit

We obtained an understanding and evaluated the design of controls that address the risks of material misstatement relating to the realizability of deferred tax assets. This included controls over management’s projected financial information that have been identified as a source of future taxable income.

To test the Company’s assessment of the realizability of deferred tax assets and the resulting valuation allowance, our audit procedures included, among others, testing the Company’s calculation of future taxable income from the reversal of existing temporary taxable differences. In addition, we evaluated projected future taxable income exclusive of reversing temporary differences and carryforwards. We involved our tax professionals to assist in evaluating the application of tax law in the Company’s consideration of the sources of future taxable income.
