# **RUBIO CPA, PC**

CERTIFIED PUBLIC ACCOUNTANTS 3500 Lenox Road NE

Suite 1500 Atlanta, GA 30326 770-690-8995

## **REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM**

To the Members of Peakstone Securities, LLC

## Opinion on the Financial Statements

We have audited the accompanying statement of financial condition of Peakstone Securities, LLC (the "Company") as of December 31 , 2025, the related statements of operations, changes in members' equity, and cash flows for the year then ended 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, 2025, and the results of its operations and its cash flows for the year then ended 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 audit 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. 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 audit 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 audit included performing procedures to assess the risks of material misstatement to 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 audit 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 audit provides a reasonable basis for our opinion.

## Supplemental Information

The information contained in Schedules I, II and III has been subjected to audit procedures performed in conjunction with the audit of the Company's financial statements. The supplemental information is the responsibility of the Company's management. Our audit procedures included determining whether the information in Schedules I, II and III reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the accompanying schedules. In forming our opinion on the accompanying schedules, we evaluated whether the supplemental information, including its form and content, is presented

{4}------------------------------------------------

in conformity with 17 C.F.R. §240.l 7a-5. In our opinion, the aforementioned supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

We have served as the Company's auditor since 2016.

## **PEAKSTONE SECURITIES, LLC NOTES TO FINANCIAL STATEMENTS December 31, 2025**

### **Note (1) Nature of Operations and Summary of Significant Accounting Policies**

### **A. Nature of Operations**

Peakstone Securities, LLC (the "Company") is an Illinois limited liability company established on February 17, 2011, and is a registered broker-dealer under the Securities Exchange Act of 1934. As a limited liability company, the members' liability is limited to their investment. The Company is registered with the Securities and Exchange Commission (SEC), the securities commissions of appropriate states, and is a member of the Financial Industry Regulatory Authority (FINRA). The Company received approval to operate as a licensed broker-dealer on March 2, 2012.

### **B. Accounts Receivable**

Accounts receivable are non-interest-bearing uncollateralized obligations receivable in accordance with the terms agreed upon with each customer. The Company regularly reviews its accounts receivable for any uncollectible amounts. The review for uncollectible amounts is based on an analysis of the Company's collection experience, customer credit worthiness, and current economic trends. Based on management's review of accounts receivable, no allowance for credit losses is considered necessary.

### **C. Cash**

The Company maintains its bank account in a high credit quality financial institution which, at times, may exceed federally insured limits.

### **D. Revenue Recognition**

Revenue from contracts with customers includes placement and advisory services related to capital raising activities and mergers and acquisitions transactions. The recognition and measurement of revenue is based on the assessment of individual contract terms. The agreements often contain nonrefundable retainer fees, and/or success fees, which may be fixed or represent a percentage of the value that the customer receives, if and when the transaction is completed ("success fees"). The Company has evaluated its nonrefundable retainer fees to ensure they related to the transfer of a good or service, as a distinct performance obligation, in exchange for the retainer.

Significant judgment is required to determine whether performance obligations are satisfied at a point in time or over time; how to allocate transaction prices where multiple performance obligations are identified; when to recognize revenue based on appropriate measure of the Company's progress under the contract; whether revenue should be presented gross or net of certain costs; and whether constraints on variable consideration should be applied due to uncertain future events. In some circumstances, significant judgment is needed to determine the timing and measure of progress appropriate for revenue recognition under a specific contract. If a promised good or service is not distinct, the Company combines that good or service with other promised goods or services until it identifies a bundle of goods or services that is distinct. In some cases, this would result in the Company accounting for all the services promised in a contract as a single performance obligation and, if unfulfilled, amounts received from such contracts would be reflected as deferred revenues on the Statement of Financial Condition.

The Company recognizes certain retainer revenue from contracts with customers at the point in time in which specified deliverables are transferred to the Company's customer. The amount of retainer revenue recognized upon the transfer of deliverables without the consummation of a success fee based transaction or formal termination of the contract was approximately \$227,500 during the year ended December 31 , 2025, which is included in investment banking revenue in the accompanying Statement of Operations.

Success fee revenue from advisory agreements is recognized at the point in time that performance under the agreement is completed (the closing date of transaction).

{10}------------------------------------------------

## **PEAKSTONE SECURITIES, LLC NOTES TO FINANCIAL STATEMENTS December 31, 2025**

#### **Note (1) Nature of Operations and Summary of Significant Accounting Policies - Continued**

### **E. Income Taxes**

The Company has elected to be taxed as a partnership under the provisions of the Internal Revenue Code and, accordingly, is generally not subject to income taxes. Instead, Members are liable for federal and state income taxes on their respective share of the taxable income of the Company. Accordingly, no provision for income tax has been provided for in the accompanying financial statements.

Under the provisions of FASB Accounting Standards Codification 740-10 (ASC 740-10), Accounting for Uncertainty in Income Taxes, the Company is required to evaluate each of its tax positions to determine if they are more likely than not to be sustained if the taxing authority examines the respective position. A tax position includes an entity's status, including its status as a pass-through entity, and the decision not to file a tax return. The Company has evaluated each of its tax positions and has determined that no provision or liability for income taxes is necessary.

The Company is subject to the Illinois 1.5% replacement tax on income. There is no Illinois replacement tax expense for the year ended December 31 , 2025.

### **F. Use of Estimates**

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses. While actual results may differ from those estimates, management does not expect the differences, if any, to have a material effect on the financial statements.

### **G. Date of Management's Review**

Subsequent events were evaluated through the date the financial statements were issued.

#### **Note (2) Net Capital Requirement**

The Company is subject to the SEC Uniform Net Capital Rule (SEC Rule 15c3-1 ), which requires the maintenance of a minimum net capital, as defined, equal to the greater of \$5,000 or 6 2/3% of aggregate indebtedness. At December 31 , 2025, the Company had net capital of \$142,856 which was \$137,856 in excess of its required minimum net capital of \$5,000. The Company's percentage of aggregate indebtedness to net capital was 9.61 %.

#### **Note (3) Related Party Transactions**

The Company has an expense sharing agreement with The Peakstone Group, LLC, an affiliated entity, for occupancy and certain general and administrative expenses provided to the Company. The Company's share of expenses is calculated based on estimated usage. Allocated expenses to the Company under the agreement amounted to approximately \$46,534 for the year ended December 31 , 2025. The balance due from affiliate on the accompanying statement of financial condition arose from an overpayment by the Company under the expense sharing agreement.

{11}------------------------------------------------

## **PEAKSTONE SECURITIES, LLC NOTES TO FINANCIAL STATEMENTS December 31, 2025**

#### **Note (3) Related Party Transactions - Continued**

Separately, the affiliate entity at times pays for and subsequently seeks reimbursement of the Company's allocated share of certain research and technology expenses. The Company expensed during 2025 approximately \$7,879 of such research and technology and insurance expenses that were paid for on its behalf by the affiliate entity. There were no amounts due to the affiliate at December 31, 2025 as a result of such payments.

Financial position and results of operations could differ if these related party transactions did not exist.

### **Note (4) Contingencies**

The Company is subject to litigation in the normal course of business. The Company has no litigation in progress at December 31, 2025.

### **Note (5) Concentration**

90% of investment banking revenues earned in 2025 were from three customers. All of accounts receivable as of December 31 , 2025 are due from one customer.

### **Note (6) Segment Reporting**

The Company's chief operating decision maker is its chief executive officer. The Company has one reportable segment: investment banking. The accounting policies of the investment banking segment are the same as those described in the summary of significant accounting policies. The chief operating decision maker assesses performance for the investment banking segment and decides how to allocate resources based on the Company's net income or loss as is reported within the accompanying statement of operations. Additionally, the chief operating decision maker uses excess net capital (see Note 2), which is not a measure of profit and loss, to make operational decisions while maintaining capital adequacy, such as whether to reinvest profits or pay distributions. The Company's operations constitutes a single operating segment and therefore, a single reportable segment, because the chief operating decision maker manages the business activities using information of the Company as a whole.
