Principles of Consolidation

The unaudited interim condensed consolidated financial statements include the financial statements of the Company and its subsidiaries. All transactions and balances among the Company and its subsidiaries have been eliminated upon consolidation.

Subsidiaries are those entities in which the Company, directly or indirectly, controls more than one half of the voting power; or has the power to govern the financial and operating policies, to appoint or remove the majority of the members of the board of directors, or to cast a majority of votes at the meeting of directors.

Cash

Cash

Cash consists of cash on hand and at banks. The Company has not experienced any losses in such accounts and does not believe the cash is exposed to any significant risk.Pursuant to the Regulations on Deposit Insurance of the People’s Republic of China, corporate legal entities are entitled to deposit insurance coverage with a maximum limit of RMB 500,000 per insured institution. This coverage applies to the aggregate principal and interest of all deposit accounts held by the same corporate entity at the same bank. Deposits within the limit are fully protected and shall be repaid in full within seven working days upon bank failure. Any amount exceeding RMB 500,000 is not covered by the deposit insurance fund and shall be settled in accordance with the bank’s liquidation process.

Prepayment, Net

Prepayment, Net

Prepayments are cash deposited or advanced to suppliers for future inventory purchases or service providers for future services. This amount is refundable and bears no interest. For any prepayments determined by management that such advances will not be in receipts of inventories, services, or refundable, the Company will recognize an allowance account to reserve such balances. Management reviews its advances to suppliers on a regular basis to determine if the allowance is adequate, and adjusts the allowance when necessary. Delinquent account balances are written-off against allowance for doubtful accounts after management has determined that the likelihood of collection is not probable. The Company’s management continues to evaluate the reasonableness of the valuation allowance policy and update it if necessary.

Lease

Lease

Under ASC Topic 842, lease assets and liabilities are recognized at the present value of the future lease payments at the lease commencement date. The interest rate used to determine the present value of the future lease payments is the Company’s incremental borrowing rate based on the information available at the lease commencement date. The Company generally uses the base, non-cancellable lease term in calculating the right-of-use assets and lease liabilities.

For operating leases, lease expense for lease payments is recognized on a straight-line basis over the lease term. Variable lease payments that do not depend on a rate or index are expensed as incurred.

The Company elected the practical expedients for an entity ongoing accounting and applied the short-term lease exception for lease arrangements with a lease term of 12 months or less at commencement. Lease terms used to compute the present value of lease payments do not include any option to extend, renew or terminate the lease that the Company is not able to reasonably certain to exercise upon the lease inception. Accordingly, operating lease right-of-use assets and liabilities do not include leases with a lease term of 12 months or less.

The Company did not adopt the practical expedient that allows lessees to treat the lease and non-lease components of a lease as a single lease component. Non-lease components include payments for building management, utilities and property tax. It separates the non-lease components from the lease components to which they relate.

The Company’s accounting for finance lease (formerly called capital lease) remains substantially unchanged. ASC Topic 842 adoption did not have a material impact on the Company’s unaudited interim condensed consolidated financial statements. On the other hand, operating lease expense is recognized on a straight-line basis over the lease term.

The Company evaluates the impairment of its right of use (ROU) assets consistent with the approach applied for its other long-lived assets. The Company reviews the recoverability of its long-lived assets when events or changes in circumstances occur that indicate that the carrying value of the asset may not be recoverable. The assessment of possible impairment is based on its ability to recover the carrying value of the asset from the expected undiscounted future pre-tax cash flows of the related operations. The Company has elected to include the carrying amount of finance and operating lease liabilities in any tested asset group and include the associated lease payments in the undiscounted future pre-tax cash flows. For the years ended October 31, 2025 and 2024, the Company did not have any impairment loss against its operating lease ROU assets.

Intangible Assets

Intangible Assets

Intangible assets mainly comprise patent right. Intangible assets are recorded at cost less accumulated amortization with no residual value. Amortization of intangible assets is computed using the straight-line method over their estimated useful lives. The amortization is recorded under the general and administrative expenses in the unaudited interim condensed consolidated statements of operation and comprehensive (loss) income.

The estimated useful lives of the Company’s intangible assets are listed below:

		Estimated useful lives (years)
Patent right		20

Revenue Recognition

Revenue Recognition

The Company recognized its revenue under Accounting Standards Codification (ASC) Topic 606, Revenue from Contracts with Customers (ASC 606). The Company recognizes revenues when its customer obtains control of promised goods or services, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods or services. The Company recognizes revenues following the five-step model prescribed under Topic 606: (i) identify contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenues when (or as) the Company satisfies the performance obligation.

Revenues are recognized when control of the promised goods or services is transferred to our customers, which may occur at a point in time or over time depending on the terms and conditions of the agreement, in an amount that reflects the consideration we expect to be entitled to in exchange for those goods or services.

The Company generates its revenues primarily from 5 sources: (1) Wastewater treatment revenue, (2) River water quality management revenue, (3) Product sales revenue, (4) Training and (5) Others. The Company recognizes revenue, excluding any VAT, when performance obligations under the terms of a contract with its customers are satisfied. This occurs when the control of the goods and services have been transferred to the customer.

Wastewater treatment segment

As of April 30, 2026, RMB 35,700,000 (approximately $5.2 millions) of the agreement that were signed but had unperformed obligations related to river water quality management project, and it was completed in June 2026. As of April 30, 2026, RMB 41,000,000 (approximately $6.0 millions) of the agreement that were signed but had unperformed obligations related to wastewater treatment revenue, and it was not yet completed as of the issuance date of this report.

(1) Wastewater treatment revenue

For wastewater treatment projects, the Company contracts with customers to provide design proposal according to customers’ need and complete the construction. The terms of pricing and payment are fixed with no discount or rebate offered, no variable consideration is involved. Apart from the completion of the construction, an assurance-type warranty promise is identified in the contract, which normally for one year. This promise is used to complete the project, and the customers cannot benefit from standalone promise. Thus, there is only one performance obligation with standard quality guarantee for wastewater treatment projects. The revenue is recognized at a point in time since the projects do not meet any of the following criteria:

1.

The customer simultaneously receives and consumes the economic benefits of the provided asset as the entity performs;

2.

The seller’s performance creates or enhances an asset controlled by the customer as the asset is created or enhanced; or

3.

The seller’s performance creates an asset with no alternative use, and the seller has an enforceable right to payment for performance completed to date.

The performance obligation is satisfied at a point of time and recognized in revenue upon the completion of project, usually at the time when the project has been passed final acceptance by customers. The control of the project is then transferred from the Company to the customers upon completion of customers’ final acceptance. Payments are due from its customers based on the payment terms established in its contracts.

The Company only provides customers with the assurance that the projects would function in accordance with agreed-upon specifications are accounted for in accordance with existing guidance on product warranties. Hence, the warranties are considered as assurance type warranties, and would be treated as a liability with no impact to revenue recognition.

(2) River water quality management revenue

For river water quality management projects, the Company contracts with customers to provide design proposal according to customers’ need and achieve the target of water quality improvement which often takes an extended period of time. The terms of pricing and payment are fixed, no variable consideration is involved. Thus, there is only one performance obligation. Revenue generated from river water quality management is recognized over time using contract cost-based input method to measure progress. Contract costs include labor, material and allocable indirect expenses. Revenue is recognized proportionally as contract costs are incurred plus estimated fees. Under this method, the extent of progress towards completion is measured based on the ratio of total cost incurred to date to the total estimated cost at completion of the performance obligation. Revenues are recorded proportionally as total costs are incurred. The customer simultaneously receives and consumes the economic benefits once the river water quality management projects are performed. Payments are due from its customers based on the payment terms established in its contracts.

The Company only provides customers with the assurance that the products would function in accordance with agreed-upon specifications are accounted for in accordance with existing guidance on product warranties. Hence, the warranties are considered as assurance type warranties, and would be treated as a liability with no impact to revenue recognition.

(3) Product sales revenue

For product sales, the Company contracts with customers to provide hydrophyte and chemical reagent, which is the only performance obligation under the contract. The terms of pricing and payment are fixed with no discount or rebate offered, no variable consideration is involved. The performance obligation is satisfied at a point of time and recognized in revenue upon the completion of delivery to the customers, usually at the time when the goods related to products sales contract is delivered to and accepted by the customers. Payments are due from its customers based on the payment terms established in its contracts.

Digital health and wellness segment

The Company enters into cooperation agreements with service partners and business partners to expand its “Digital Health Center” (数字康养中心)门店 and partner network. Each agreement requires the partner to pay a nonrefundable upfront “Startup Service Package” (启动服务包) fee, including training service, core product package and supporting service. The Company should recognize the full upfront fee as Contract liabilities. Under ASC 606, the upfront cooperation fees should be treated as transaction price and allocated to identified performance obligations within the “Startup Service Package” (启动服务包). Revenue shall be recognized when each performance obligation is satisfied. Revenue recognition should be disaggregated based on the distinct performance obligations: (1) tangible products revenues was recognised at the point in time upon delivery (Product sales revenue); (2) training services revenues was recognised over the service period (Training revenue); and (3) one-time Q&A supporting services revenue was recognised at the point in time upon suppurting or 3 days after the delivery of training manual (Others).

Timing of revenue recognition may differ from the timing of invoicing to customers. In accordance with ASC 340-40-25-1, an entity shall recognize as an asset the incremental costs of obtaining a contract with a customer if the entity expects to recover those costs.

The revenue is recognized when control of the promised is rendered over the service period and the payment from customers is not contingent on a future event, and the right to consideration in exchange that the Company has transferred to a customer is only conditioned on the passage of time. The contract assets as of April 30, 2026 and October 31, 2025 are as follows:

Selling expenses

Selling expenses

Selling expenses consist primarily of salaries and welfare expenses to sales and marketing personnel and costs associated with use by sales function, such as travelling expenses, business entertainment expense and other sales related expenses. These expenses are charged to the unaudited interim condensed consolidated statements of operation and comprehensive (loss) income as incurred.

Comprehensive income

Comprehensive income

The Company applies ASC 220, Comprehensive Income (“ASC 220”), with respect to reporting and presentation of comprehensive income and its components in a full set of financial statements. Comprehensive income is defined to include all changes in equity of the Company during a period arising from transactions and other event and circumstances except those resulting from investments by shareholders and distributions to shareholders. For the six months ended April 30, 2026 and 2025, the Company’s comprehensive income includes net income, and other comprehensive income (loss) consists of a foreign currency translation adjustment resulting from the Company’s subsidiaries not using the U.S. dollar as their functional currencies.

Fair Value Measurements

Fair Value Measurements

U.S. GAAP establishes a three-tier hierarchy to prioritize the inputs used in the valuation methodologies in measuring the fair value of financial instruments. This hierarchy also requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The three-tier fair value hierarchy is:

Level 1 – observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.

Level 2 – include other inputs that are directly or indirectly observable in the market place.

Level 3 – unobservable inputs which are supported by little or no market activity.

The carrying value of the Company’s financial instruments, including cash, accounts and other receivables, other current assets, accounts and other payables, and other short-term liabilities approximate their fair value due to their short maturities.

Foreign Currency and Foreign Currency Translation

Foreign Currency and Foreign Currency Translation

An entity’s functional currency is the currency of the primary economic environment in which it operates, normally that is the currency of the environment in which the entity primarily generates and expends cash. Management’s judgment is essential to determine the functional currency by assessing various indicators, such as cash flows, sales price and market, expenses, financing and inter-company transactions and arrangements. The functional currency of the Company is the United States dollar (“U.S. dollar”). The functional currency of the Company’s subsidiaries in the Hong Kong, China is the Hong Kong dollar (“HKD”). The functional currency of the Company’s operations in the PRC is the Chinese Yuan or Renminbi (“RMB”).

The unaudited interim condensed consolidated financial statements are presented in U.S. dollars. Assets and liabilities are translated into U.S. dollars at the current exchange rate in effect at the balance sheet date, and revenues and expenses are translated at the average of the exchange rates in effect during the reporting period. Shareholders’ equity accounts are translated using the historical exchange rates at the date the entry to shareholders’ equity was recorded, except for the change in retained earnings during the period, which is translated using the historical exchange rates used to translate each period’s income statement. Differences resulting from translating functional currencies to the reporting currency are recorded in accumulated other comprehensive income in the unaudited interim condensed consolidated balance sheets.

Foreign currency transactions denominated in currencies other than the functional currency are translated into the functional currency using the exchange rates prevailing at the dates of the transactions. Monetary assets and liabilities denominated in foreign currencies at the balance sheet date are re-measured at the applicable rates of exchange in effect at that date. Gains and losses resulting from foreign currency re-measurement are included in the statements of operation and comprehensive (loss).

Translation of amounts from RMB into U.S. dollars has been made at the following exchange rates:

Balance sheet items, except for equity accounts
April 30, 2026			RMB6.8273 to $1
October 31, 2025			RMB7.1169 to $1

Income statement and cash flows items
For the six months ended April 30, 2026			RMB6.9555 to $1
For the six months ended April 30, 2025			RMB7.2681 to $1

Commitments and Contingencies

Commitments and Contingencies

In the normal course of business, the Company is subject to contingencies, including legal proceedings and claims arising out of the business that relate to a wide range of matters, such as government investigations and tax matters.
