# REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Members' and Board of Members' of White Mountain Capital, LLC

# Opinion on the Financial Statements

<sup>I</sup> have audited the accompanying statement of financial condition of White Mountain Capital Group, LLC as of December 31, 2025, and the related notes (collectively referred to as the financial statements). In my opinion, the financial statements present fairly, in all material respects, the financial position of White Mountain Capital Group, LLC as of December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

## Basis for Opinion

These financial statements are the responsibility of White Mountain Capital Group, LLC's management. My responsibility is to express an opinion on White Mountain Capital Group, LLC's financial statements based on my audit. <sup>I</sup> am <sup>a</sup> public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and am required to be independent with respect to White Mountain Capital Group, LLC in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

<sup>I</sup> conducted my audit in accordance with the standards of the PCAOB. Those standards require that <sup>I</sup> 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. My 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 <sup>a</sup> test basis, evidence regarding the amounts and disclosures in the financial statements. My audit also included evaluating the accounting principles used and significant estimates made by management, as evaluating the overall presentation of the financial statements. <sup>I</sup> believe that my audit provides <sup>a</sup> reasonable basis for my opinion.

### Note 1- Organization and Nature of Business

White Mountain Capital, LLC ("the Company") is <sup>a</sup> securities broker. The Company also engages in proprietary trading of equity securities. The Company's customers are primarily located in the New York Tri-State Area. The Company does not carry customer accounts and does not process or safe-keep customer funds or securities and is therefore exempt from Rule 15c3-3 of the Securities and Exchange Commission. The Company is registered with the Securities and Exchange Commission (SEC) and is <sup>a</sup> member of the Financial Industry Regulatory Authority (FINRA).

The Company entered into <sup>a</sup> clearing agreement with Hilltop Securities, that automatically renews, to execute and clear transactions and carry accounts on <sup>a</sup> fully disclosed basis on behalf of the Company's customers. The minimum clearing and execution charges are \$7,500 per month. The Company has deposited \$100,000 with its clearing firm as security for its transactions with them which is the balance at December 31, 2025. The Company also maintains other cash at the clearing organization.

### Note 2- Summary of Significant Accounting Policies

#### Basis of Presentation

The Company prepares its financial statements on the accrual basis of accounting in accordance with the Accounting Standards Codification that was approved by the Financial Accounting Standards Board as being the single source of authoritative United States accounting and reporting standards.

#### Uses of Estimates

The preparation of financial statements in conformity with generally accepted accounting principles 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 the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

### Cash and Cash Equivalents

The Company considers all highly liquid debt instruments purchased with original maturities of three months or less to be cash and cash equivalents. As of December 31, 2025, the Company had no deposits at any financial institution in excess of the Federal Deposit Insurance Corporation limit of \$250,000.

#### Fair Value Measurement

\_ASB ASC 820 defines fair value, establishes <sup>a</sup> framework for measuring fair value, and establishes <sup>a</sup> fair value hierarchy which prioritizes the inputs to valuation techniques. Fair value is the price that would be received to sell an asset or paid to transfer <sup>a</sup> liability in an orderly transaction between market participants at the measurement date. A fair value measurement assumes that the transaction to sell the asset or liability or, in the absence of <sup>a</sup> principal market, the most advantageous market for the asset of liability. Valuation techniques that are consistent with the market, income or cost approach, as specified by FASB ASC 820 are used to measure fair value.

{7}------------------------------------------------

# Note <sup>2</sup> - Summary of Significant Accounting Policies (continued)

The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels:

Level <sup>1</sup> inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities the Company has the ability to access.

Level <sup>2</sup> inputs are inputs (other than quoted prices included within Level 1) that are observable for the asset or liability, either directly or indirectly.

Level 3 are unobservable inputs for the asset or liability and rely on management's own assumptions about the assumptions that market participants would use in pricing the asset or liability. (The unobservable inputs should be developed based on the best information available in the circumstances and may include the Company's own data.)

Following is description of the valuation methodologies used for assets measured at fair value.

Stocks: Unrestricted quoted market price at major stock markets

Stocks: Restricted quoted market price at major stock markets unable to trade due to stock restriction

The methods described above may produce <sup>a</sup> fair value calculation that may not be indicative of net realizable value or reflective of future fair values. Furthermore, while the Company believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in <sup>a</sup> different fair value measurement at the reporting date.

There were no levels to measure at December 31, 2025.

# Note <sup>2</sup> - Summary of Significant Accounting Policies (continued)

#### Revenue Recognition

Revenue is measured based on <sup>a</sup> consideration specified in <sup>a</sup> contract with<sup>a</sup> customer, and excludes any sales incentives and amounts collected on behalf of third parties. The Company recognizes revenue when it satisfied <sup>a</sup> performance obligation by transferring control over <sup>a</sup> product or service to <sup>a</sup> customer.

Commissions: This includes performance obligations related to transactions that is subject to SEA Rule 10b-10 for any renumeration that would need to be disclosed. It also includes any transaction when the Company is engaged as an agent. It does not include net gains or losses from transactions made by the Company when acting as <sup>a</sup> principal, or riskless principal.

Principal transactions, including the related expenses, which are recorded on <sup>a</sup> trade date basis, including realized and unrealized gains and losses for the purchase or sale of securities on <sup>a</sup> first-in, first-out basis. Unrealized gains and losses for securities are recorded on <sup>a</sup> mark-to-mark basis at the date of the financial statements.

Interest income and expense is recorded on an accrual basis which is calculated based on contractual interest rates.

#### Income Taxes

The Company was organized as <sup>a</sup> limited liability company, and accordingly, no provision is required for federal and state income taxes. Under the Internal Revenue Code and similar state regulations, the Company is treated as <sup>a</sup> partnership and the taxable income or loss of the Company is taxed to the members. However, the Company is subject to Florida taxes.

Segment Reporting: The Company Is engaged in <sup>a</sup> single line of business as <sup>a</sup> securities broker dealer, which is comprised of several classes of services, including principal transactions and agency transactions. The Company has identified its Chief Executive Officer 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 <sup>a</sup> measure of profit and loss, to make operational decisions while maintaining capital adequacy, such as whether to reinvest profits or pay dividends. The Company's operations constitute <sup>a</sup> single operating segment and therefore, <sup>a</sup> single reportable segment, because the CODM manages the business activities using information from the Company as <sup>a</sup> whole. The accounting policies used to measure the profit and loss of the segment are the same as those described in the summary of significant accounting policies.

{9}------------------------------------------------

## Note <sup>2</sup> - Summary of Significant Accounting Policies (continued)

As of December 31, 2025, the Company did not have any unrecognized tax benefits or liabilities. The Company is no longer subject to tax examinations for years previous to the three-year statute of limitations and there are presently no ongoing tax examinations.

#### Guaranteed Payments to Members

Guaranteed payments to members that are intended as compensation for services rendered are accounted for as expenses rather than as allocations of net income.

#### Note 3 - Related Party Transactions

The Company is <sup>a</sup> member of <sup>a</sup> group of affiliated entities in the financial services industry. The Company earns commission income from an affiliated investment partnership (IP) as well as from officers and employees of companies in the affiliated group and their family members. In connection with the Company's broker agreement, under certain circumstances, the Company also earns fees on the IP's short cash balances held at the broker and on the margin interest paid by the IP to the broker.

The Company received commission income of approximately \$892,000 from affiliates and other related parties.

#### Note 4 - Membership Interests

After paying the initial capital contribution to class <sup>B</sup> units, the remaining distributions shall be pro rata according to ownership percentage.

#### Note 5 - Financial Instruments With Off Balance Sheet Risk

The Company is engaged in various trading and brokerage activities whose counterparties include primarily broker-dealers, banks, and other financial institutions. In the event counterparties do not fulfill their obligations, the Company may be exposed to risk. The risk of default depends on the credit worthiness of the counter party. It is the Company's policy to review, as necessary, the credit standing of each counterparty. The Company's exposure to risk associated with nonperformance of customers in fulfilling their contractual obligations pursuant to securities transactions can be directly impacted by volatile trading markets which may impair <sup>a</sup> customer's 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 nonperformance by its customers. The Company seeks to control the aforementioned risks by requiring customers to maintain margin collateral in compliance with the clearing broker's internal guidelines. The Company monitors its customers' activity by reviewing information it receives from its clearing broker on <sup>a</sup> daily basis and requiring customers to deposit additional collateral, or reduce positions, when necessary.

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

## Note 6 - Securities Sold Short

The Company is subject to certain inherent risks arising from its activities of selling securities short. The ultimate cost of the Company to acquire these securities may exceed the liability reflected in the financial statements. In addition, the Company is required to maintain collateral with the broker to secure these short positions.

### Note 7- Concentrations of Credit Risk

As <sup>a</sup> securities broker and dealer, the Company is engaged in various securities trading and brokerage activities servicing <sup>a</sup> diverse group of domestic and foreign corporations, institutional and individual investors. <sup>A</sup> substantial portion of the Company's transactions are executed with and on behalf of institutional investors including other brokers and dealers, mortgage brokers, commercial banks, U.S. governmental agencies, mutual funds and other financial institutions.
