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. Our audit 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 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. #### Auditor's Report on Supplemental Information The information in Schedules "1" through "3" 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 supplemental information reconciles to the financial statements or the {5}------------------------------------------------ underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with 17 C.F.R. §240.17a-5. In our opinion, the information in Schedules "1" through "3" 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 2009. Herauit, & Ullomann, I.C.

ORGANIZATION AND NATURE OF BUSINESS** Seaport Securities Corporation, a New York "S" Corporation, is a broker-dealer registered with the SEC and a member of the NYSE, FINRA, and SIPC. It offers execution services to other broker-dealers and "buy" side institutions (mutual funds, money managers, pension funds, hedge funds, banks, etc.) as well as offering discount brokerage services including online brokerage services to the general investing public. #### **2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES** #### Revenue Recognition: The Company recognizes revenue in accordance with ASC Topic 606, "Revenue from Contracts with Customers". The core principal of the standard is that revenue is recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration the Company expects to be entitled to receive in exchange for those goods and services. Commissions - The Company earns commissions on securities orders it executes on behalf of the customer. The related commission income and clearing expense are recognized on a trade-date basis. All such transactions are cleared through another broker-dealer on a fully disclosed basis. Mutual Fund Fees - The Company earns 12B-1 fee income from customer money market fund balances. The money market funds are offered by the Company's clearing broker. The 12B-1 income is computed daily and paid monthly by the clearing firm. The income is recognized by the Company on a monthly basis. Margin Balance Income - The Company earns interest income on customer margin balances. The firm's clearing broker shares the income it earns with the Company based upon total customer margin balances held by the clearing broker. The income is computed daily and paid monthly by the clearing firm. The income is recognized by the Company on a monthly basis. Fee Income - The Company earns management fees and referral fees for services performed in accordance with customer agreements. Under agreed terms, these fees are billed based on a percentage of assets under management and collected quarterly. #### Securities Transactions: Profit and loss arising from all securities transactions entered into for the account and risk of the Company are recorded on a settlement date basis. The Company uses the specific identification method for determining the cost basis in computing realized gains and losses. {11}------------------------------------------------ ## **2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES** (Continued) Marketable securities are valued at market value based on the closing sales prices as listed on the securities exchange on the last business day of each month. The resulting difference between cost and market is included in income as gain on investment securities. Accrued Commission Receivable: The Company records accrued commission receivable for trading commissions earned but not received as of December 31, 2025. It has not recorded any provision for credit losses because management believes that the accrued commission receivable will be fully collected. # Valuation of Securities: The Company has adopted the Fair Value Measurements Topic of the Financial Accounting Standards Board Accounting Standards Codification (FASB ASC). It defines fair value as the price that the Company would receive upon selling an investment in a timely transaction to an independent buyer in the principal or most advantageous market for the investment. It also established a three-tier hierarchy to maximize the use of observable market data and minimize the use of unobservable inputs and to establish classification of fair value measurements for disclosure purposes. Inputs refer broadly to the information that market participants would use in pricing the asset or liability, including assumptions about risk, and are classified as observable or unobservable. The three-tier hierarchy of inputs is summarized in the three broad levels listed below. Level 1 – quoted prices in active markets for identical investments Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, credit risk, etc.) Level 3 – significant unobservable inputs (including the Company's own assumptions in determining the fair value of investments) The Company's investment in marketable securities consists entirely of Level 1 securities utilizing valuation techniques consisting exclusively of quoted market prices. # Cash and cash equivalents: For purposes of the statement of cash flows, the Company has defined cash equivalents as highly liquid investments, with original maturities of less than three months that are not held for sale in the ordinary course of business. ## Use of Estimates: The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results may differ from those estimates. {12}------------------------------------------------ # **2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES** (Continued) Subsequent Events: The Company has evaluated subsequent events through February 27, 2026, the date that the financial statements were available to be issued. ## **3. CASH-RESTRICTED** Cash of \$295,762 has been segregated in a special deposit account with the clearing broker for the benefit of customers under an agreement with the clearing broker. ## **4. SUPPLEMENTARY CASH FLOW INFORMATION** #### **Reconciliation of Cash, Cash Equivalents, and Restricted Cash:** The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Statement of Cash Flows that sum to the total of the same such amounts shown in the Statement of Cash Flows: | Cash and cash equivalents | \$6,061,654 | |----------------------------------------------------------------|-------------| | Restricted cash | 295,762 | | Total cash, cash equivalents, and restricted cash shown in the | | | Statement of Cash Flows | \$6,357,416 | ## **5. NET CAPITAL REQUIREMENTS** Pursuant to the net capital provisions of Rule 15c3-1 of the Securities Exchange Act of 1934, the Company is required to maintain a minimum net capital, as defined under such provisions, of \$100,000 or 6 2/3% of aggregate indebtedness as defined, if larger. Net capital and aggregate indebtedness fluctuate from day to day but, at December 31, 2025, the Company's net capital exceeds such capital requirements by \$9,285,641 and the ratio of aggregate indebtedness to net capital is .0366 to 1. ## **6. INCOME TAXES** The shareholders of the Company have elected to treat the corporation as an "S" Corporation for Federal and New York State tax purposes. As a result, in lieu of corporation income taxes, the stockholders are taxed on the proportionate share of the Company's taxable income. However, the Company is subject to New York City corporation taxes. The Company's income tax returns for 2022, 2023 and 2024 are subject to examination by tax authorities, generally for three years after they were filed. {13}------------------------------------------------ # **6. INCOME TAXES** (Continued) The Company computes its New York City tax in accordance with the requirements of the Income Tax Topic of the FASB's ASC. The provision for income taxes includes the following at December 31, 2025: | State and local tax expense | Current | Deferred | Total | |-----------------------------|----------|----------|----------| | | \$25,406 | \$0 | \$25,406 | | | \$25,406 | \$0 | \$25,406 | Deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of the Company's assets and liabilities. The tax effect of the temporary differences giving rise to the Company's deferred tax liability results from unrealized gains on marketable securities. The provision for deferred income taxes is not a material component of the financial statements. # **7. PENSION PLAN** The Company has a profit-sharing pension plan for all full-time employees who have completed at least one full year of service. The Company did not make a contribution to the plan for the year ended December 31, 2025. ## **8. CONCENTRATIONS OF CREDIT RISK** As a securities broker, the Company is engaged in buying and selling securities for a diverse group of institutional and individual investors. The Company introduces these transactions for clearance to another broker-dealer on a fully disclosed basis. The Company's exposure to credit risk associated with non-performance of customers in fulfilling their contractual obligations pursuant to securities transactions can be directly impacted by volatile trading markets which may impair customers' ability to satisfy their obligations to the Company and the Company's ability to liquidate the collateral at an amount equal to the original contracted amount. The agreement between the Company and its clearing broker provides that the Company is obligated to assume any exposure related to such non-performance by its customers. The Company seeks to control the aforementioned risks by requiring customers to maintain margin collateral in compliance with various regulatory requirements and the clearing broker's internal guidelines. The Company monitors its customer activity by reviewing information it receives from its clearing broker on a daily basis, and requiring customers to deposit additional collateral, or reduce positions, when necessary. The Company maintains cash in bank accounts which, at times, may exceed federally insured limits or where no insurance is provided. The Company has not experienced any losses in such accounts and does not believe it is exposed to any significant credit risk on cash. {14}------------------------------------------------ ## **9. OPERATING LEASE OBLIGATION** The Company conducts its operations from premises leased on a month to month basis. Rent expense is \$86,636 for the year ended December 31, 2025, which includes utilities and real estate taxes. #### **10. RELATED PARTY TRANSACTIONS** The Company made reimbursements in the amount of \$50,145 to an officer/owner for expenses incurred on behalf of the Company. # **11. BUSINESS SEGEMNTS** The Company has determined that it has one reportable segment, given the common nature of the Company's operations, products and services, and regulatory environment. It provides brokerage and advisory services to institutional and individual investors from which it derives its revenues and incurs expenses. The Company has identified its president and CEO as the chief operating decision maker (CODM) as specified in ASU 2023-7, who uses net income to evaluate the results of the business and make decisions about resource allocation. The Company's operations constitute a single operating segment and therefore, a single reporting segment, because the CODM manages the business activities using information of the Company as a whole. All required segment financial information can be found directly in the financial statements. The accounting policies used for our reportable segment are the same as those described in the summary of significant accounting policies. {15}------------------------------------------------ # **SEAPORT SECURITIES CORPORATION COMPUTATION OF NET CAPITAL UNDER SEC RULE 15c3-1 DECEMBER 31, 2025** | SHAREHOLDERS' EQUITY, PER STATEMENT OF FINANCIAL
