Summary of Significant Accounting Policies [Abstract]

Going Concern

For the six months ended June 30, 2026, the Company incurred a net loss of $6,782,691 and negative cash flows from operating activities. These factors raise substantial doubt regarding the Company’s ability to continue as a going concern. During the next twelve months, the Company intends to fund its operations with revenue from revenue-producing activities by intensifying sales strategies and key account management, and exploring additional equity and debt financing. If the Company cannot secure additional short-term capital, it may cease operations. These financial statements and related notes thereto do not include any adjustments that might result from these uncertainties.

Use of Estimates

In preparing the unaudited interim condensed consolidated financial statements in conformity with U.S. GAAP, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the dates of the unaudited interim condensed consolidated financial statements, as well as the reported amounts of revenue and expenses during the reporting periods. Significant items subject to such estimates and assumptions include, but are not limited to, the assessment of the allowance for doubtful accounts, the realizability of deferred income tax assets and cost of assurance-type warranty. The current economic environment has increased the degree of uncertainty inherent in those estimates and assumptions.

The Company is required to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, expenses, and related disclosure of contingent assets and liabilities. On an on-going basis, the Company evaluates its estimates based on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates.

Restricted Cash

Restricted cash represents cash that cannot be withdrawn without the permission of third parties. The Company’s restricted cash is substantially cash balance in designated bank accounts as security for payment processing. Restriction on the use of such cash and the interest earned thereon is imposed by the banks and remains effective throughout the term of the security period. Upon maturities of the security period, the bank’s deposits are available for general use by the Company.

Fair Value of Financial Instruments

Fair Value of Financial Instruments – the Company adopted ASC 820-10-50, “Fair Value Measurements”. This guidance defines fair value, establishes a three-level valuation hierarchy for disclosures of fair value measurement and enhances disclosure requirements for fair value measures. The three levels are defined as follows:

●

Level one – Quoted market prices in active markets for identical assets or liabilities;

●

Level two – Inputs other than level one inputs that are either directly or indirectly observable; and

●

Level three – Unobservable inputs developed using estimates and assumptions, which are developed by the reporting entity and reflect those assumptions that a market participant would use.

The Company’s financial instruments consist principally of cash and cash equivalents, restricted cash, short-term investments, non-current financial investments, accounts receivable, accounts payable, short-term debts, notes payable and other liabilities.

Acquisition

These consolidated financial statements include the operations of acquired businesses from the date of the acquisitions. On November 25, 2025, the Company completed the acquisition of a 51% equity interest of an operating subsidiary of iTonic Corporation, a Delaware corporation. The decision of whether to consolidate an entity for financial reporting purposes requires consideration of majority voting interests, as well as effective economic or other control over the entity.

We account for business combinations using the acquisition method. Under this method, the identifiable assets acquired, liabilities assumed, and any non-controlling interest are recorded at their estimated fair values. We engage third-party valuation specialists to assist in determining fair values. Our income approach valuation process depends on the assets being valued. Goodwill is measured as the excess of consideration transferred over the fair value of the assets acquired and the liabilities assumed. The allocation of the purchase price relies on estimates and significant assumptions to determine the fair values of identifiable assets acquired and liabilities assumed, particularly for intangible assets. These estimates are based on all available information as of the acquisition date and may involve assumptions about the timing and amounts of future revenues and expenses associated with an asset.

Management applied judgment in determining the fair value of the acquired assets in the iTonic Corporation acquisitions. The judgments made in determining the estimated fair value of the assets acquired, as well as the estimated useful lives of those assets, can materially affect net income in periods subsequent to the acquisition through depreciation and amortization. In particular, judgment was applied with respect to determining the fair value of acquired customer relationships, intangible assets, which involved the use of estimates and significant assumptions with respect to the timing and amounts of cash flow projections, the revenue growth rates, the customer attrition rates, the EBITDA margins, and the discount rate. Unanticipated events and circumstances may occur, which may affect the accuracy or validity of such assumptions or estimates.

Goodwill and Other Intangibles

The Company accounts for business acquisitions in accordance with GAAP. Goodwill in such acquisitions is determined as the excess of fair value over amounts attributable to specific tangible and intangible assets. GAAP specifies criteria to be used in determining whether intangible assets acquired in a business combination must be recognized and reported separately from goodwill. Amounts assigned to goodwill and other identifiable intangible assets are based on independent appraisals or internal estimates.

In accordance with GAAP, the Company does not amortize goodwill. Management evaluates the remaining useful life of an intangible asset that is not being amortized each reporting period to determine whether events and circumstances continue to support an indefinite useful life. Amortizable intangible assets, including customer relationships are amortized on a straight-line basis over 5 years.

The Company tests goodwill for impairment annually as of December 31, or if an event occurs or circumstances change that indicate that the fair value of the entity, or the reporting unit, may be below its carrying amount (a “triggering event”). Whenever events or circumstances change, entities have the option to first make a qualitative evaluation about the likelihood of goodwill impairment. If impairment is deemed more likely than not, management would perform the two-step goodwill impairment test. Otherwise, the two-step impairment test is not required. In assessing the qualitative factors, the Company assessed relevant events and circumstances that may impact the fair value and the carrying amount of the reporting unit. The identification of the relevant events and circumstances and how these may impact a reporting unit’s fair value or carrying amount involve significant judgements and assumptions. The judgement and assumptions include the identification of macroeconomic conditions, industry and market considerations, overall financial performance, Company specific events and share price trends, an assessment of whether each relevant factor will impact the impairment test positively or negatively, and the magnitude of such impact.

If a quantitative assessment is performed, a reporting unit’s fair value is compared to its carrying value. A reporting unit’s fair value is determined based upon consideration of various valuation methodologies, including the income approach, which utilizes projected future cash flows discounted at rates commensurate with the risks involved and multiples of current and future earnings. If the fair value of a reporting unit is less than its carrying amount, an impairment charge is recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value; however, the loss recognized cannot exceed the total amount of goodwill allocated to that reporting unit.

We test goodwill for impairment annually in the fiscal fourth quarter or whenever events or circumstances indicate the carrying value may not be recoverable.

The useful life of intangible assets has been assessed as follows:

Category		Useful Life
Property rights		5 years
Software		5 years
License		5 years
Customer relationships		5 years
IP		5 years

Revenue recognition

The Company adopted ASC Topic 606, Revenue from Contracts with Customers, effective as of January 1, 2020. Accordingly, the unaudited interim condensed consolidated financial statements for the six months ended June 30, 2025 and 2026 are presented under ASC 606. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Revenue is the transaction price the Company expects to be entitled to in exchange for the promised services in a contract in the ordinary course of the Company’s activities and is recorded net of value-added tax (“VAT”). To achieve that core principle, the Company applies the following steps:

Step 1: Identify the contract (s) with a customer;

Step 2: Identify the performance obligations in the contract;

Step 3: Determine the transaction price;

Step 4: Allocate the transaction price to the performance obligations in the contract;

Step 5: Recognize revenue when (or as) the entity satisfies a performance obligation.

The Company is primarily engaged in the industry of medical instrumental software, with required medical instruments with which such software operates. Our main business during the reporting periods are sales of Particle Implantation Radiotherapy Treatment Planning System (FTTPS), sales of Medical Auxiliary Supplies, and others. No practical expedients were used when adoption ASC 606. Revenue recognition policies for each type of revenue stream are as follows:

Sales of FTTPS:

The Company sells FTTPS with computers, monitors or other medical equipment required by customers’ specific needs. The FTTPS sales contracts are primarily on a fixed price basis, which requires the Company to provide core software, a set of hardware as peripherals to operate the software, and related services, including transportation, packaging, installation and training based on customers’ specific needs. The execution timeline of these sales contracts is typically within three months.

The hardware, software and services are considered as a single performance obligation, because the complete functionality required for brachytherapy is achieved only when these components are used in conjunction with one another. The customers cannot benefit from the hardware, software or services alone, but only upon the integration of software, hardware, installation and training. Typically, installation and training can be completed within two days after delivery. Revenue from sales of FTTPS is recognized at a point in time after the Company transferred control of the Company’s products and provided the services, generally upon the customer’s acceptance of the products and services. Beijing Feitian has not entered into any loss contracts to date.

In certain sales agreements, the Company provides an assurance-type warranty to the customers’ warranty. This type of warranty promises to repair or replace a delivered good or service if it does not perform as expected. Since an assurance-type warranty guarantees the functionality of a product, the warranty is not accounted for as a separate performance obligation, and thus no transaction price is allocated to it. Rather, to account for an assurance-type warranty the vendor should estimate and accrue a warranty liability when the promised products or service is delivered to the customer under ASC 460. Generally, the estimated claim rates of warranty are based on actual warranty experience or Company’s best estimate. There were no such reserves for the six months ended June 30, 2025 and 2026, because the Company’s historical warranty expenses were immaterial to the Company’s consolidated financial statements.

Sales of Medical Auxiliary Supplies:

The Company sells Medical Auxiliary Supplies to customers for the operation of FTTPS system. The promised goods are considered as a single performance obligation because the sales of Medical Auxiliary Supplies are independent and unrelated to sales of FTTPS. Revenue from sales of Medical Auxiliary Supplies is recognized at the point in time when the goods are delivered and the customer has accepted the delivery.

Foreign currency translation and transactions

The reporting currency of the Company is U.S. dollars (“$”) and the accompanying consolidated financial statements have been expressed in U.S. dollars. The Company’s principal country of operations is the PRC. The financial position and results of its operations are determined using the Chinese Yuan (“RMB”), the local currency, as the functional currency. The Company’s consolidated financial statements have been translated into the reporting currency U.S. dollars. The results of operations and the consolidated statements of cash flows denominated in foreign currency are translated at the average rate of exchange during the reporting period. Assets and liabilities denominated in foreign currencies at the balance sheet date are translated at the applicable rates of exchange in effect at that date. The equity denominated in the functional currency is translated at the historical rate of exchange at the time of capital contribution. Because cash flows are translated based on the average translation rate, amounts related to assets and liabilities reported on the consolidated statements of cash flows will not necessarily agree with changes in the corresponding balances on the consolidated balance sheets. Translation adjustments arising from the use of different exchange rates from period to period are included as a separate component of accumulated other comprehensive income included in consolidated statements of changes in shareholders equity. Gains and losses from foreign currency transactions and balances are included in the results of operations.

The following table outlines the currency exchange rates that were used in preparing the consolidated financial statements:

		June 30,		June 30,
		2025		2026
Period-end spot rate	$	1 = RMB 7.1636	$	1=RMB 6.7851
Average rate	$	1 = RMB 7.2526	$	1=RMB 6.8624

Segment reporting

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker (CODM), or decision making-group, in deciding how to allocate resources and in assessing performance.

In November 2023, FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures, which expands public entities’ segment disclosures, among others, requiring disclosure of significant segment expenses that are regularly provided to the CODM and included within each reported measure of segment profit or loss; an amount and description of its composition for other segment items; and interim disclosures of a reportable segment’s profit or loss and assets. This new guidance was effective for us beginning with the annual report for the year ended December 31, 2024, and applied retrospectively to all prior periods presented. The impact of the adoption of this guidance was not material to our financial position or results of operations, as the requirements impact only segment reporting disclosures in our notes to financial statements.

The Company operates as one operating and reportable segment. All of the Company’s long-lived assets, comprised of property and equipment, are based in China. All of the Company’s revenue was in China for the six months ended June 30, 2025 and 2026, based on the location of the customers.

The Company’s CODM is our Chief Executive Officer. Our CODM makes decisions on resource allocation, evaluates operating performance, and monitors budget versus actual results using net income (loss). There are no reconciling items or adjustments between segment income (loss) and net income (loss) as presented in our statements of operations. The CODM does not review assets in evaluating the segment results and therefore such information is not presented.
