#### REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

# To the Stockholder of Martinson & Company, Ltd.

We have reviewed management's statements, included in the accompanying Martinson & Company, Ltd. Exemption Report pursuant to SEC Rule 17a-5, in which (1) Martinson & Company, Ltd. (the Company) did not claim an exemption under paragraph (k) of 17 C.F.R. §240.15c3-3, and (2) the Company is filing this Exemption Report relying on Footnote 74 of the SEC Release No. 34-70073 adopting amendments to 17 C.F.R. § 240.17a-5 because the Company limits its business activities exclusively to providing nontransactional and non-portfolio management advisory services such as valuation report or general consulting on a fee for service basis and receiving transaction for identifying potential merger and acquisition or private placement of debt or equity opportunities for clients, and the Company (1) did not directly or indirectly receive, hold, or otherwise owe funds or securities for or to customers, (other than money or other consideration received and promptly transmitted in compliance with paragraph (a) or (b)(2) of Rule 15c2-4 and/or funds received and promptly transmitted for effecting transactions via subscriptions on a subscription way basis where the funds are payable to the issuer or its agent and not to the Company); (2) did not carry accounts of or for customers; and (3) did not carry PAB accounts (as defined in Rule 15c3-3) throughout the most recent fiscal year without exception.

Martinson & Company, Ltd.'s management is responsible for compliance with Footnote 74 of the SEC Release No. 34-70073 adopting amendments to 17 C.F.R. § 240.17a-5, and related SEC Staff Frequently Asked Questions and its statements.

Our review was conducted in accordance with the standards of the Public Company Accounting Oversight Board (United States) and, accordingly, included inquiries and other required procedures to obtain evidence about Martinson & Company, Ltd.'s compliance with Footnote 74 of the SEC Release No. 34-70073 adopting amendments to 17 C.F.R. § 240.17a-5, and related SEC Staff Frequently Asked Questions. A review is substantially less in scope than an examination, the objective of which is the expression of an opinion on management's statements. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to management's statements referred to above for them to be fairly stated, in all material respects, based upon the Company's business activities contemplated by Footnote 74 of the SEC Release No. 34-70073 adopting amendments to 17 C.F.R. § 240.17a-5, and related SEC Staff Frequently Asked Questions.

### NOTES TO FINANCIAL STATEMENTS

### ( 1 ) Nature of business and significant accounting policies

Nature of business - Martinson & Company, Ltd. (the Company) provides investment banking and advisory services to corporate clients regarding strategic financial and general business matters. The Company is registered as a broker-dealer with the United States Securities and Exchange Commission and the Financial Industry Regulatory Authority, Inc. From time to time, the Company performs services for clients with revenues sufficient to define this client as a major client. While such relationships are considered significant relationships, the clients change annually. For the fiscal year ended June 30, 2026 the Company's investment banking activities and advisory services generated \$24,000 in revenue.

### Significant accounting policies:

Accounts receivable - Accounts receivable are customer obligations due under normal trade terms requiring payment within 30 days of the invoice date. Unpaid accounts receivable which are past due are not charged a monthly service fee.

Accounts receivable are stated at the amount billed to the customer. Customer account balances with invoices dated over 90 days old are considered delinquent.

Payments of accounts receivable are allocated to the specific invoices identified on the customer's remittance advice or, if unspecified, are applied to the oldest invoices on the customer's account.

The carrying amount of accounts receivable is reduced by a bad debt allowance that reflects management's best estimate of the accounts that will not be collected. Management reviews all accounts receivable balances and determines an appropriate course of action on a delinquent account.

Revenue recognition - Investment banking revenues, which include advisory and placement fees, are recorded when the performance obligation for the transaction is satisfied under the terms of each engagement. Expenses associated with such transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded. Investment banking revenues are presented gross of related client reimbursed deal expenses. Expenses for completed deals are reported separately in deal-related expenses on the statements of operations.

The Company's advisory fees generally consist of a nonrefundable up-front fee and a success fee. The nonrefundable fee is recorded as deferred revenue upon receipt and recognized at a point in time when the performance obligation is satisfied, or when the transaction is deemed by management to be terminated. Management's required in determining when a transaction is considered to be terminated.

The substantial majority of the Company's advisory and placement fees (i.e., the success related advisory fee) are considered variable consideration and recognized when it is probable that the variable consideration will not be reversed in a future period. The variable consideration is considered to be constrained until satisfaction of the performance obligation.

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

#### NOTES TO FINANCIAL STATEMENTS

The Company's performance obligation is generally satisfied at a point in time upon the closing of a strategic transaction, completion of a financing or placement arrangement, or some other defined outcome (e.g., providing a fairness opinion). At this time, the Company has transferred control of the promised service and the customer obtains control. As these arrangements represent a single performance obligation of the transaction price is not necessary. The Company has elected to apply the following optional exemptions regarding disclosure of its remaining performance obligations: (i) the Company's performance obligation is part of a contract that has an original expected duration of one year or less and/or (ii) the variable consideration is allocated entirely to a wholly unsatisfied promise to transfer a distinct service that forms part of a single performance obligation.

As discussed in Note 2, the Company receives support fees revenue from two employees to cover the employee share of the operating and regulatory expenses of the company. Support fees are deemed to be earned for the year of operations that the fees are supporting. There are no remaining performance obligations related to support fees received in the year ended June 30, 2026.

Income taxes – Effective July 1, 2018, the Company, with the consent of its stockholder, has elected to be taxed under sections of the federal and state income tax laws which provide that, in lieu of corporation income taxes, the stockholder separately accounts for the Company items of income, deductions, losses, and credits. Therefore, these statements do not include any provision for corporate income taxes.

The Company reviews and assesses its tax positions taken or expected to be taken in tax returns. Based on this assessment, the Company determines whether it is more likely than not that the position would be sustained upon examination by tax authorities. The Company's assessment has not identified any significant positions that it believes would not be sustained under examination.

The Company files tax returns in the United States federal jurisdiction and in Minnesota. Uncertain tax positions include those related to tax years that remain subject to examination. The Company's federal and state tax returns are generally open for examination for three years following the date filed.

Concentration of credit risk - As a broker and dealer, the Company is engaged in various securities trading and brokerage activities servicing a diverse group of corporate and individual investors. The Company's exposure to credit risk associated with the nonperformance of these customers in fulfilling their contractual obligations pursuant to securities, options and commodities transactions can be directly impacted by volatile securities markets, credit markets and regulatory changes which may impair the customer's ability to satisfy their obligations to the Company.

Use of estimates - The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

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

### NOTES TO FINANCIAL STATEMENTS

Subsequent events policy - Subsequent events have been evaluated through the date of the report of independent registered public accounting firm which is the date the financial statements were issued and did not note any events requiring reporting or disclosures.

Single Reportable Segment - The Company is engaged in a single line of business as a securities broker-dealer which is comprised of investment banking services described in Note 4. The Company has identified its Chief Executive as the chief operating decision maker ("CODM"), who uses net income to evaluate the results of the business, predominantly in the forecasting process, to manage the Company. Additionally, the CODM uses excess net capital which is not a measure of profit and loss, to make operational decisions while maintaining capital adequacy, such as whether to maintain profits or pay distributions. The Company's operations constitute a single operating segment and therefore, a single reportable segment, because the CODM manages the business activities using information of the Company as a whole. The accounting policies used to measure the profit and loss of the segment are the same as those described in the policies listed below.

#### ( 2 ) Related party

During the year ended June 30, 2026 the Company received support fees totaling \$5,348 from two employees pursuant to expense sharing reimbursement agreements

#### Net capital requirements (3)

The Company is subject to the Securities and Exchange Commission Uniform Net Capital Rule 15c3-1, which requires the maintenance of minimum net capital and requires that the ratio of aggregate indebtedness to net capital, both as defined, shall not exceed 15 to 1. In addition, restrictions may be imposed to prohibit equity withdrawals or cash dividends if the resulting net capital ratio would exceed 10 to 1. At June 30, 2026, the Company had net capital as defined by Rule 15c3-1 of \$25,595 which exceeds its required net capital of \$5,000 by \$20,595. The Company's ratio of aggregate indebtedness to net capital was .002 to 1 at June 30, 2026.

#### ( 4 ) Exemption

Because the Company carries no customer accounts and receives no customer funds or securities, it is exempt from Rule 15c3-3 under the 1934 Act in reliance upon Footnote 74 of the SEC Release No. 34-70073 adopting amendments to 17 C.F.R. § 240.17a-5.

The Company is exempt from Rule 15c3-3 of the Securities and Exchange Commission. Therefore, the Company is not required to make the periodic computation of reserve requirements for the exclusive benefit of customers.

## ( 5 ) Commitments and Contingencies

The Company has no material commitments or contingencies at June 30, 2026 which require disclosure or recognition.
