2. Summary of Significant Accounting Policies

(a) Basis of presentation

The financial statements for Yellowstone Group Ltd for three months ended June 30, 2025 are prepared in accordance with accounting principles generally accepted in the United States of America (“US GAAP”). The Company has adopted March 31 as its fiscal year end.

(b) Use of estimates

Management uses estimates and assumptions in preparing these financial statements in accordance with US GAAP. Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities in the balance sheets, and the reported revenue and expenses during the periods reported. Actual results may differ from these estimates.

(c) Cash and Cash Equivalents

Cash and cash equivalents are carried at cost and represent cash on hand, demand deposits placed with banks or other financial institutions and all highly liquid investments with an original maturity of three months or less as of the purchase date of such investments.

(d) Accounts Receivable, net

Accounts receivable, net represents those receivables derived from the ordinary course of business and are recorded net of allowance that reflects the Company’s best estimate of the amounts that will not be collected. In determining collectability of the accounts receivables, the Company considers factors in assessing the expected credit losses, including historical credit loss experience, credit quality of customers, aging of the receivables, and specific facts and circumstances.

Accounts Receivable and allowance for credit losses. Trade receivables are uncollateralized customer obligations due under normal trade terms. The Company has established procedures to monitor credit risk. The estimated allowance is based on an analysis that estimates the amount of its total customer receivable balance that is not collectible. This analysis includes assessing a default probability to customers’ receivable balances, which is influenced by several factors including (i) current market conditions, (ii) periodic review of customer credit worthiness, and (iii) review of customer receivable aging and payment trends. Write-offs are recorded at the time a customer receivable is deemed uncollectible. In accordance with Accounting Standards Update (“ASU”) 2016-13, Financial Instruments – Credit Losses, Measurement of Credit Losses on Financial Instruments the Company recognizes expected credit losses based on a broader range of reasonable and supportable information to inform credit loss estimates. The Company accrued allowance for credit losses of nil for the three months ended June 30, 2025.

(f) Revenue Recognition

Revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The amount of revenue that is recorded reflects the consideration that the Company expects to receive in exchange for those goods and services. The Company applies the following five-step model in order to determine this amount:

The Company adopted ASU 2014-09, Revenue from Contracts with Customers (Topic 606). Under Topic 606, the Company records revenue when persuasive evidence of an arrangement exists, delivery has occurred, the fee is fixed or determinable and collectability is probable. The Company records revenue from the provision of services upon delivery of the finalized Personal Financial Report to the customer.

(g) Earnings Per Share

The Company reports earnings per share in accordance with ASC 260 “Earnings Per Share”, which requires presentation of basic and diluted earnings per share in conjunction with the disclosure of the methodology used in computing such earnings per share. Basic earnings per share excludes dilution and is computed by dividing income available to common stockholders by the weighted average common stock outstanding during the period. Diluted earnings per share takes into account the potential dilution that could occur if securities or other contracts to issue common stock were exercised and converted into common stock. Further, if the number of common stock outstanding increases as a result of a stock dividend or stock split or decreases as a result of a reverse stock split, the computations of a basic and diluted earnings per share shall be adjusted retroactively for all periods presented to reflect that change in capital structure.

The Company’s basic earnings per share is computed by dividing the net income available to holders by the weighted average number of the Company’s common stock outstanding. Diluted earnings per share reflects the amount of net income available to each common stock outstanding during the period plus the number of additional shares that would have been outstanding if potentially dilutive securities had been issued.

(h) Income Taxes

The Company accounts for income taxes using the asset and liability method prescribed by ASC 740 “Income Taxes”. Under this method, deferred tax assets and liabilities are determined based on the difference between the financial reporting and tax bases of assets and liabilities using enacted tax rates that will be in effect in the years in which the differences are expected to reverse. The Company records a valuation allowance to offset deferred tax assets if based on the weight of available evidence, it is more-likely-than-not that some portion, or all, of the deferred tax assets will not be realized. The effect on deferred taxes of a change in tax rates is recognized as income or loss in the period that includes the enactment date.

New U.S. federal tax legislation, commonly referred to as the Tax Cuts and Jobs Act (the “U.S. Tax Reform”), was signed into law on December 22, 2017. The U.S. Tax Reform modified the U.S. Internal Revenue Code by, among other things, reducing the statutory U.S. federal corporate income tax rate from 35% to 21% for taxable years beginning after December 31, 2017; limiting and/or eliminating many business deductions; migrating the U.S. to a territorial tax system with a one-time transaction tax on a mandatory deemed repatriation of previously deferred foreign earnings of certain foreign subsidiaries; subject to certain limitations, generally eliminating U.S. corporate income tax on dividends from foreign subsidiaries; and providing for new taxes on certain foreign earnings. Taxpayers may elect to pay the one-time transition tax over eight years, or in a single lump-sum payment.

(i) Comprehensive Loss

Comprehensive Loss includes all changes in equity except those resulting from investments by owners and distributions to owners. For the years presented, the Company’s total comprehensive loss includes net loss.

(j) Related parties

Parties, which can be a corporation or individual, are considered to be related if the Company has the ability, directly or indirectly, to control the other party or exercise significant influence over the other party in making financial and operating decisions. Companies are also considered to be related if they are subject to common control or common significant influence.

(k) Fair Value Measurement

Accounting Standards Codification (“ASC”) 820 “Fair Value Measurements and Disclosures”, which defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. The statement clarifies that the exchange price is the price in an orderly transaction between market participants to sell the asset or transfer the liability in the market in which the reporting entity would transact for the asset or liability, that is, the principal or most advantageous market for the asset or liability. It also emphasizes that fair value is a market-based measurement, not an entity-specific measurement, and that market participant assumptions include assumptions about risk and effect of a restriction on the sale or use of an asset.

This ASC establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below:

Level 1: Unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities;

Level 2: Quoted prices in markets that are not active, or inputs that are observable, either directly or indirectly, for substantially the full term of the asset or liability; and

Level 3: Prices or valuation techniques that require inputs that are both significant to the fair value measurement and unobservable (supported by little or no market activity).

(l) Recently issued and adopted accounting pronouncements

The Company reviews new accounting standards as issued. Management has not identified any other new standards that it believes will have a significant impact on the Company’s financial statements.
