REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of CEA Industries Inc.:

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of CEA Industries Inc. (“the Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations, changes in shareholders’ equity , and cash flows for each of the years in the two-year period December 31, 2024 and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements referred to above 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 years in the two-year period 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 audit. 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 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) related to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgements. 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 matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates.

Revenue Recognition – Contracts with Multiple Performance Obligations

Critical Audit Matter Description

As described in Note 2 to the financial statements, the Company’s contracts with customers often include the promise to transfer multiple goods and services to a customer. Distinct promises within a contract are referred to as performance obligations and are accounted for as separate units of account. Management assesses whether each promised good or service is distinct for the purpose of identifying the performance obligations in the contract. This assessment involves subjective determinations and requires management to make judgments about the individual promised goods or services and whether such goods or services are separable from the other aspects of the contractual relationship. The Company’s performance obligations include various distinct goods and services such as equipment and various engineering services. When multiple performance obligations are identified within a contract, management exercises judgement in allocating the transaction price amongst the various performance obligations. In addition, when discounts are provided for a particular contract, the discount is allocated to each performance obligation proportionally based upon the stand-alone selling price of each performance obligation.

We determined that performing procedures related to the identification of performance obligations in revenue contracts and allocation of the transaction price to the respective performance obligations is a critical audit matter as there was significant judgment by management in identifying performance obligations in revenue contracts and allocating the consideration, which in turn led to a high degree of auditor judgment, subjectivity and effort in performing procedures to evaluate whether performance obligations in revenue contracts were appropriately identified by management and consideration was appropriately allocated.
