In our opinion, the statement of financial condition presents fairly, in all material respects, the financial position of the America. #### Basis for Opinion This financial statement is the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statement 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 statement is 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 of the financial statement, 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 statement. 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 statement. We believe that our audit provides a reasonable basis for our opinion. We have served as the Company's auditor since 2023.

The Company is a registered broker-dealer in securities under the Securities Act of 1934 and is a member of the Financial Industry Regulatory Authority ("FINRA") and Securities Investor Protection Corporation ("SIPC"). The Company provides financial and investment services to predominantly retail clients. The Company operates as an introducing broker-dealer in which all brokerage activity is handled by a clearing broker, Hilltop Securities, LLC. The Company is headquartered in Naples, Florida, and has customers located throughout the United States. #### BASIS OF ACCOUNTING The financial statements of the Company have been prepared on the accrual basis of accounting and accordingly reflect significant receivables, payables and other liabilities. ### CASH The Company considers all short-term investments with original maturity of three months or less to be cash equivalents. The Company had no cash equivalents at December 31, 2025. #### SECURITIES TRANSACTIONS Securities transactions and the related revenues and expenses are recorded in the financial statements on a trade date basis. #### INCOME TAXES The Company is organized as a limited liability company and is taxed as a disregarded entity for income tax purposes. Accordingly, it is not subject to federal and state income taxes and makes no provision for income taxes in its financial statements. The taxable income or loss of the Company is includible in the income tax returns of its member. Taxable years ended from December 31, 2022, through present are subject to IRS and other jurisdictions' tax examinations. The Company is not currently under audit by any tax jurisdiction. #### INCOME TAX UNCERTANTIES The Company follows FASB guidance for how uncertain tax positions should be recognized, measured, disclosed and presented in the financial statements. This requires the evaluation of tax positions taken or expected to be taken in the course of preparing the Company's tax returns to determine whether the tax positions are "more-likely-than-not" of being sustained "when challenged" or "when examined" by the applicable tax authority. Tax positions not deemed to meet the more-likely-than-not threshold would be recorded as a tax expense and liability in the current year. Management has evaluated the effect of guidance surrounding uncertain income tax positions and concluded that the Company has no material uncertain tax positions that require recognition or disclosure in its financial statements. {7}------------------------------------------------ # McDermott Investment Services, LLC NOTES TO FINANCIAL STATEMENTS, Continued DECEMBER 31, 2025 #### 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 and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. # LEASES In accordance with ASU 2016-02 – Leases (Topic 842), the Company recognizes all leasing activity with initial terms in excess of twelve months on the statement of financial condition with lease liabilities and corresponding right-of-use assets based on the present value of lease payments. # ACCOUNTS RECEIVABLE Receivable from brokers and dealers represent amounts due from its clearing broker relating to customer securities transactions introduced by the Company. The company had no receivable from broker or dealers at December 31, 2025. Accounts receivable represent commissions due from mutual funds, insurance companies and trust sponsors and reimbursements due from advisors. In accordance with ASU 2016-13 - Current Expected Credit Losses ("CECL"), the Company recognizes credit impairment losses using an expected loss model for trade and other receivables. The Company considers an allowance for credit losses based on factors surrounding the credit risk of customers, past events, current conditions, reasonable and supportable forecasts concerning the future, and other information. Management has determined that no allowance for credit losses is necessary at December 31, 2025. # SUBSEQUENT EVENTS Management has evaluated events through the date the financial statements were issued and has determined that no additional disclosures are necessary. # NOTE 2: REVENUE FROM CONTRACTS WITH CUSTOMERS The Company recognizes revenue under ASU 2014-09, Revenue Recognition from Contracts with Customers ("Topic 606"). Accounts receivable from revenue from contracts with customers as of December 31, 2025, and January 1, 2025 were \$313,334 and \$158,758, respectively. The Company had no contract assets or liabilities as of January 1, 2025 or December 31, 2025. {8}------------------------------------------------ # McDermott Investment Services, LLC NOTES TO FINANCIAL STATEMENTS, Continued DECEMBER 31, 2025 #### NOTE 3: SEGMENT REPORTING The Accounting Standards Update (ASU) 2023-07 issued by the Financial Accounting Standards Board (FASB) introduced enhancements to segment reporting requirements for public entities, including brokerdealers. The update aimed to improve the transparency and usefulness of financial disclosures for investors and other stakeholders. ASU 2023-07 disclosure requirements are effective for fiscal years starting after December 15, 2023. The Company has identified its Managing Member as the Chief Operating Decision Maker as specified in the ASU 2023-07. Company management reviewed the ASU 2023-07 disclosure requirements and determined that no additional disclosures are required as the Company has only one reportable segment. ### NOTE 4: PROPERTY AND EQUIPMENT The Company capitalizes major capital expenditures. Depreciation is calculated on a straight-line method over the estimated useful lives of the related assets that range from two to five years. | Furniture and fixtures | \$9,273 | | |--------------------------------|----------|--| | Equipment | 15,847 | | | Leasehold improvements | 19,710 | | | | 44,830 | | | Less: accumulated depreciation | (27,486) | | | Property and equipment, net | \$17,344 | | # NOTE 5: RIGHT OF USE ASSET AND OPERATING LEASE LIABILITY | Furniture and fixtures

Off balance sheet credit risk exists with respect to these transactions due to the possibility that customers may be unable to fulfill their contractual commitments wherein the clearing broker-dealer may charge any losses it incurs to the Company. The Company seeks to minimize this risk through procedures designed to monitor the credit worthiness of its customers and that customer transactions are executed properly by the clearing broker-dealer. At December 31, 2025, cash was held on deposit at a diversified U.S. financial institution insured by the Federal Deposit Insurance Corporation ("FDIC"). The Company's cash balance regularly exceeds the FDIC insured limit of \$250,000. #### NOTE 7: CONCENTRATIONS The Company offers a diversified array of products to investors.

The Company and MIA are owned by the same individual. Under the Agreement, MIA provided office space, furniture and telecommunications services to the Company and called for the Company to pay MIA 50% of its monthly incurred expenses per the rental agreement with the landlord. The Company provides execution services to MIA in connection with MIA's transactions at Hilltop Securities, LLC. The Company does not charge MIA for these services. #### NOTE 9: CONTINGENCIES The Company may, from time to time, be involved in judicial, regulatory and arbitration proceedings concerning matters arising in connection with the conduct of the Company's business.
