QUARTA-RAD,

INC. AND SUBSIDIARIES

Notes

to the unaudited Condensed and Consolidated Financial Statements

NOTE 1 - BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements of Quarta-Rad, Inc. and subsidiaries (the “Company”) as of March 31, 2026, and for the three months ended March 31, 2026 and 2025, have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 8 of Regulation S-X of the Securities and Exchange Commission (“SEC”).

In the opinion of management, the accompanying unaudited condensed consolidated financial statements contain all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the Company’s financial position as of March 31, 2026, and the results of operations and cash flows for the periods presented. The condensed consolidated balance sheet as of December 31, 2025 was derived from the audited consolidated financial statements included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025.

Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to SEC rules and regulations for interim reporting. These interim condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2025. Interim results are not necessarily indicative of the results that may be expected for the full fiscal year or any future interim period.

Beginning in 2024, the Company significantly reduced and began winding down its legacy radiation detection equipment business and shifted its primary operational focus to Sellavir, Inc., its wholly owned subsidiary. Sellavir is focused on the development and commercialization of artificial intelligence-driven software solutions for the call center and customer engagement industry, including the CenterEye platform.

The

Company has experienced recurring operating losses and negative cash flows from operations and had an accumulated deficit of approximately $532,500 as of March 31, 2026. These factors raise substantial doubt about the Company’s ability to continue as a going concern within one year after the issuance date of these financial statements. Management’s plans include continued development and commercialization of the Company’s software platforms, expansion of strategic partnerships, pursuit of additional customer engagements, and raising additional capital, if necessary. There can be no assurance that these plans will be successful.

The Company’s majority shareholder has historically provided financial support for operations and may continue to provide additional support, as needed. In addition, the Company is evaluating strategic alternatives related to its legacy operations, including a potential separation or spin-off of certain historical business activities; however, no definitive transaction has been approved or completed as of the filing date of this report.

NOTE

2 - NATURE OF BUSINESS

Quarta-Rad, Inc. (the “Company”) was historically engaged in the distribution of radiation detection devices, including Geiger counters, to consumers and commercial customers in North America and Europe. Beginning in 2024, the Company significantly reduced and began winding down these legacy operations, and such activities are no longer expected to represent a significant component of the Company’s future business.

The Company’s primary operational focus has shifted to Sellavir, Inc. (“Sellavir”), its wholly owned subsidiary. Sellavir is an artificial intelligence and analytics company focused on developing software solutions for the call center and customer engagement industry. Sellavir’s core product, CenterEye, is a software platform designed to leverage AI and advanced analytics to improve call center operations, enhance customer engagement, and support operational efficiencies through integration with major cloud-based contact center platforms.

NOTE

3 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principlesof Consolidation

The consolidated financial statements include the accounts Quarta-Rad, Inc. and its wholly-owned subsidiary Sellavir, Inc. All significant intercompany balances and transactions have been eliminated in consolidation.

Useof Estimates and Assumptions

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“U.S. GAAP”) requires management to make estimates and judgments that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting periods.

Significant estimates made by management include, among others, the recognition of revenue from related party arrangements, the recoverability of related party receivables and notes receivable, and the valuation of deferred tax assets. The Company bases its estimates on historical experience, knowledge of current conditions, and assumptions believed to be reasonable under the circumstances. The Company reviews its estimates on an ongoing basis. Actual results may differ materially from those estimates.

NotesReceivable – related party

Notes Receivable – related party consists of loan agreements entered into by Sellavir discussed in Note 4. Amounts payable marked to value in functional currency at the balance sheet date where the Company records foreign transaction gain or loss. The Company’s functional currency is the United States Dollar.

Concentrationof Credit Risk

Credit is extended to online customers based on an evaluation of their financial condition, and collateral is generally not required. The Company performs ongoing credit evaluations of its customers and provides an allowance for doubtful accounts as appropriate.

One related party customer accounted for substantially all accounts receivable of Sellavir as of March 31, 2026. One related party customer accounted for all the revenue for Sellavir for the three months ended March 31, 2026 and March 31, 2025. In addition, one selling platform/distributor accounted for substantially all accounts receivable of Quarta-Rad as of March 31, 2026 and December 31, 2025.

Earningsper Share

The Company’s basic earnings per share are calculated by dividing its net income available to common stockholders by the weighted average number of common shares outstanding for the period. The Company’s dilutive earnings per share is calculated by dividing its net income available to common shareholders by the diluted weighted average number of shares outstanding during the period. The diluted weighted average number of shares outstanding is the basic weighted number of shares adjusted for any potentially dilutive debt or equity. There were no potentially dilutive instruments outstanding during the periods ended March 31, 2026 and 2025.

FairValue of Financial Instruments

The Company’s financial instruments as defined by Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 825, “Financial Instruments” include cash, trade accounts receivable, and accounts payable and accrued expenses. All instruments, except marketable securities are accounted for on a historical cost basis, which, due to the short maturity of these financial instruments, approximates fair value at March 31, 2026 and December 31. 2025. Marketable securities are level one assets recorded at fair value.

FASB ASC 820 “Fair Value Measurements and Disclosures” defines fair value, establishes a framework for measuring fair value in accordance with U.S. GAAP, and expands disclosures about fair value measurements. ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

●	Level<br> 1. Observable inputs such as quoted prices in active markets;
●	Level<br> 2. Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly; and
●	Level<br> 3. Unobservable inputs in which there is little or no market data, which requires the reporting<br> entity to develop its own assumptions.

The Company’s investment securities consist of common and preferred stock. Substantially all the Company’s investments are Level 1. The fair market value is based on quoted prices in active markets for identical assets. Financial assets are measured at fair value on a recurring basis. The following table provides information at March 31, 2026, and December 31, 2025 about the Company’s financial assets measured at fair value on a recurring basis.

RevenueRecognition

The Company follows guidance from FASB Accounting Standards Codification ASC Topic 606, Revenue from Contracts with Customers (“ASC 606”). The guidance sets forth a five-step revenue recognition model. The underlying principle of the standard is that a business or other organization will recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects what it expects to receive in exchange for the goods or services.

The Company generates revenue primarily from software development services, consulting services, and limited product sales associated with its legacy radiation detection business.

Notes

to the unaudited Condensed and Consolidated Financial Statements

Revenue is measured based on consideration specified in a contract with a customer. A contract with a customer exists when we enter into an enforceable contract with a customer. The contract is based on either the acceptance of standard terms and conditions on the websites for e-commerce customers and via telephone with our third-party call center for our print media and direct mail customers, or the execution of terms and conditions contracts with retailers and wholesalers. These contracts define each party’s rights, payment terms and other contractual terms and conditions of the sale. Consideration is typically paid prior to shipment via credit card or check when our products are sold direct to consumers or approximately 30 days from the time control is transferred when sold to wholesalers, distributors and retailers. We apply judgment in determining the customer’s ability and intention to pay, which is based on a variety of factors including the customer’s historical payment experience and, in some circumstances, published credit and financial information pertaining to the customer.

A performance obligation is a promise in a contract to transfer a distinct product to the customer, which for us is transfer of devices to our customers. Performance obligations promised in a contract are identified based on the goods that will be transferred to the customer that are both capable of being distinct and are distinct in the context of the contract, whereby the transfer of the goods is separately identifiable from other promises in the contract. We have concluded the sale of goods and related shipping and handling are accounted for as the single performance obligation.

The transaction price of a contract is allocated to each distinct performance obligation and recognized as revenue when or as the customer receives the benefit of the performance obligation. The transaction price is determined based on the consideration to which we will be entitled to receive in exchange for transferring goods to the customer. We issue refunds to e-commerce and print media customers, upon request, within 30 days of delivery. We estimate the amount of potential refunds at each reporting period using a portfolio approach of historical data, adjusted for changes in expected customer experience, including seasonality and changes in economic factors. For retailers, distributors and wholesalers, we do not offer a right of return or refund, and revenue is recognized at the time products are shipped to customers. In all cases, judgment is required in estimating these reserves. Actual claims for returns could be materially different from the estimates. There was no reserve for sales returns and allowances at March 31, 2026 and December 31, 2025, respectively.

We recognize revenue when we satisfy a performance obligation in a contract by transferring control over a product to a customer when a product is shipped. Taxes assessed by a governmental authority that are both imposed on and concurrent with a specific revenue-producing transaction, that are collected by us from a customer, are excluded from revenue. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfilment cost and are included in cost of product sales.

We recognize consulting revenue over time as services are performed. Invoiced amounts are determined based on the level of work completed by contractors, measured against predetermined project milestones. These milestones are defined in the client contract and are tied to specific deliverables or stages in the agreed-upon project timeline.

RecentAccounting Pronouncements

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. The update is intended to improve the navigability of the guidance in ASC 270 and clarify the applicability, form, content, and disclosure requirements for interim financial statements. The amendments also clarify that entities should disclose events and changes occurring since the end of the most recent annual reporting period that have a material impact on the entity. The guidance is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact this guidance may have on its consolidated financial statements and related disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement—Reporting Comprehensive Income (Topic 220): Expense Disaggregation Disclosures. This update requires entities to disaggregate operating expenses into specific categories, such as salaries and wages, depreciation, and amortization, to provide enhanced transparency into the nature and function of expenses. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, with early adoption permitted. ASU 2024-03 may be applied retrospectively or prospectively. The Company is currently evaluating the impact of this standard on its financial statement presentation and disclosures.

We have adopted all recently issued accounting pronouncements. The adoption of the new accounting pronouncements is not anticipated to have a material effect on our operations.

Risksand Uncertainties

The Company is continuing to expand its artificial intelligence-driven software business through the development of new software platforms, consulting services, and AI-based solutions for the call center and customer engagement industry. Beginning in 2024, the Company significantly reduced its legacy radiation detection equipment business and shifted its primary operational focus to Sellavir and the development of the CenterEye platform.

The Company’s future success depends in part on its ability to successfully develop, commercialize, and achieve market acceptance of its AI-driven software products and services. The Company operates in a rapidly evolving and highly competitive industry characterized by changing technologies, evolving customer requirements, and frequent introductions of new products and services.

The success of the CenterEye platform depends on the Company’s ability to develop features that meet customer needs, maintain compatibility with third-party platforms, respond to technological advancements, and address software defects, cybersecurity risks, and operational challenges in a timely manner. There can be no assurance that the Company will successfully commercialize CenterEye or achieve significant market acceptance. Failure to do so could adversely affect the Company’s financial condition, results of operations, and future growth prospects.

NOTE

4–NOTE RECEIVABLE – RELATED PARTY

In March 2023, Sellavir entered into a loan agreement with a related Thai corporation for the purpose of purchasing land for development. In May 2023, the Company’s Chief Executive Officer and majority shareholder became the Chief Executive Officer and a minority shareholder of the Thai entity.

Under

the terms of the agreement, the Thai corporation is obligated to repay Sellavir 9,000,000 Thai Baht (approximately $261,038 at inception), which includes a premium of $16,038, plus interest at a rate of 15% per annum.

In

January 2024, the loan agreement was amended to reduce the interest rate to 10% and to provide Sellavir with an additional 3% participation in the selling price of the underlying property. As a result of this modification, the Company recorded a loss of $8,188.

The

loan is denominated in Thai Baht and is remeasured at each reporting date. The carrying value of the note was $254,719 and $263,970 as of March 31, 2026 and December 31, 2025, respectively. As a result of foreign currency fluctuations, the Company recorded a foreign currency translation loss of $10,053 for the three months ended March 31, 2026, compared to a foreign currency translation gain of $23,244 for the year ended December 31, 2025.

The

unamortized premium related to the loan was $6,412 and $7,214 as of March 31, 2026 and December 31. 2025, respectively, and is being amortized over the life of the loan.

Pursuant to amendments in January 2024 and May 2025, principal payments are deferred until April 1, 2027, after which quarterly principal payments are due through April 1, 2031. Interest is payable at maturity. The loan is secured by land located in Thailand.

Sellavir

received a principal payment of $14,897 in April 2024. As of March 31, 2025, the Company ceased recognizing accrued interest income on the loan.

Item2. Management’s Discussion and Analysis of Financial Conditions and Results of Operations

The following is management’s discussion and analysis of financial condition and results of operations and is provided as a supplement to the accompanying unaudited condensed financial statements and notes to help provide an understanding of our financial condition, results of operations and cash flows during the periods included in the accompanying unaudited condensed financial statements.

In this Quarterly Report on Form 10-Q, “Company,” “the Company,” “us,” and “our” refer to Quarta-Rad, Inc., a Delaware corporation, unless the context requires otherwise.

We intend the following discussion to assist in the understanding of our financial position and our results of operations for the three months ended March 31, 2026, and 2025. You should refer to the Financial Statements and related Notes in conjunction with this discussion.

Resultsof Operations

General

We were incorporated under the laws of the State of Delaware on November 29, 2011, with a fiscal year end of December 31. We were initially formed to distribute and sell radiation detection devices and related products to consumers and businesses in North America.

Beginning in 2013, we purchased products from Quarta-Rad, Ltd. (“QRR”), a company located in Russia, and shipped products to third-party online retailers and resellers for distribution. In recent periods, the Company has reduced its focus on its historical radiation detection product line and has shifted its primary business focus toward software development and AI-driven technologies.

During April 2020, we acquired Quarta-Rad USA, Inc., a Delaware corporation, as a wholly owned subsidiary. No consideration was paid for the shares. The purpose of the acquisition was to separate certain operations into a separate entity. There was no activity, assets, or liabilities in the subsidiary through March 31, 2026.

During December 2020, we acquired Sellavir, Inc. (“Sellavir”), an AI software company focused on advanced analytics, image processing, and call center software solutions. Sellavir’s technology platform is designed to assist organizations in analyzing video and operational data through proprietary AI technologies.

Sellavir has developed CenterEye, a software platform intended to simplify the use and management of cloud-based call center systems. CenterEye is designed to enhance call center operations through AI-driven analytics, automation, and operational monitoring capabilities.

Prior to April 2024, our chief executive officer and director, Victor Shvetsky, and our former director and president, Alexey Golovanov, were our only employees. In April 2024, Mr. Golovanov resigned from the Company.

| 15 |

| --- |

The Company’s current focus is the continued development and commercialization of CenterEye and related AI-driven software solutions. Management is actively pursuing opportunities in the United States, Japan, and other international markets. The Company currently generates revenue primarily through relationships with its Japanese reseller associated with Sellavir’s software and development services.

Our administrative office is located at 1201 N. Orange St., Suite 700, Wilmington, DE 19801.

Our business strategy is focused on expanding the development, marketing, and deployment of CenterEye and related technologies. We aim to enhance call center efficiency and customer engagement through AI-driven solutions while pursuing strategic relationships with businesses requiring advanced customer service and operational analytics platforms.

SellavirConsulting

We expanded our operations through the acquisition of Sellavir in December 2020. Sellavir leverages its expertise in neural networks and artificial intelligence technologies to provide customized software development and AI-related services to clients. These services include image processing applications, operational analytics, and call center software solutions.

Our business model is focused on identifying customer-specific operational needs and developing software solutions to address those needs. Currently, the Company’s revenue associated with Sellavir operations is generated primarily through its Japanese reseller relationships.

The Company acquired Sellavir to:

● leverage Sellavir’s AI capabilities in connection with future technology initiatives;

● expand operations beyond the Company’s historical radiation detection product business; and

● pursue opportunities within the call center software industry through the development and commercialization of CenterEye.

CenterEye is intended to be offered as a subscription-based software platform, which management believes may provide recurring revenue opportunities in future periods. Sellavir began recognizing revenue related to call center software operations during 2024.

Management’sPlan to Address Going Concern Considerations

The Company has experienced recurring operating losses, primarily due to limited revenues. The Company’s current financial conditions and recurring losses raise substantial doubt about its ability to continue as a going concern.

Management intends to fund operations through existing cash balances, revenues generated from operations, related party support, and, if necessary, additional capital raises or strategic financing arrangements. There can be no assurance that such financing will be available on acceptable terms or at all.

ConsolidatedTotals:

Planof Operation

Our business strategy has evolved from primarily marketing radiation detection products to focusing on the development and commercialization of CenterEye, our proprietary AI-driven call center software platform. We aim to enhance call center efficiency, operational visibility, and customer engagement through advanced analytics, automation, and monitoring solutions. While we continue to maintain our online presence related to our historical product lines, management’s primary efforts are directed toward software development, marketing, and establishing strategic relationships with businesses requiring advanced customer service and operational analytics platforms.

While we continue to maintain our website at www.quartarad.com, we have increased our focus on Sellavir’s operations and related marketing efforts as part of our long-term business strategy.

During December 2020, Quarta-Rad acquired Sellavir, Inc., a Delaware corporation under common control, as a wholly owned subsidiary in exchange for 333,333 shares of common stock. The value of the shares issued was approximately $170,000 on the date of issuance.

Sellavir is an AI software and analytics company focused on advanced operational analytics, image processing, and call center software technologies. Sellavir’s platform utilizes artificial intelligence (“AI”) and proprietary technologies designed to assist organizations in analyzing operational and video-based data to improve business performance and customer engagement.

Sellavir, Inc., our wholly-owned subsidiary, is currently focused on the continued development and commercialization of CenterEye, a call center software platform that leverages AI and advanced analytics to improve call center operations. CenterEye is designed to provide real-time insights, operational metrics, monitoring capabilities, and customer engagement tools intended to improve efficiency and customer satisfaction.

Management is actively pursuing opportunities in Japan, the United States, and other international markets through reseller relationships and direct marketing efforts.

We intend to implement the following tasks within the next twelve months:

SoftwareDevelopment:

We intend to continue investing in the development and enhancement of CenterEye to meet the evolving needs of the call center industry. This includes adding new features, improving user experience, enhancing reporting and analytics capabilities, and improving scalability and platform functionality.

Marketing:

(Estimated cost $25,000 - $75,000). We intend to increase our marketing efforts to generate additional leads, reseller opportunities, and customer relationships for CenterEye and related software solutions. Marketing efforts may include digital advertising, website enhancements, promotional materials, and attendance at industry-related events and conferences.

| 19 |

| --- |

Partnershipsand Client Acquisition:

(Estimated cost $20,000). We intend to pursue strategic relationships with call center operators, technology providers, and resellers. Management intends to focus on pilot projects, reseller arrangements, and initial software deployments designed to demonstrate the effectiveness of CenterEye and support future recurring revenue opportunities.

HistoricalProduct Operations:

While the Company continues to maintain limited activities associated with its historical radiation detection product business, management’s primary operational focus has shifted toward AI-driven software and analytics solutions.

Our management does not currently anticipate the need to hire additional full-time employees over the next three months, as the services currently provided by our officers, directors, and independent contractors are expected to be sufficient for current operations. As our software development and commercialization activities expand, we may engage additional independent contractors or consultants to support development, marketing, operational, or business development activities.

We currently do not own material equipment that we intend to sell in the near future, do not have any off-balance sheet arrangements, and have not paid material expenses on behalf of our directors outside the ordinary course of business.

Off-BalanceSheet Arrangements

None.

The ReformAct provides a safe harbor for forward-looking statements to encourage companies to provide prospective information about themselvesso long as they identify these statements as forward-looking and provide meaningful cautionary statements identifying important factorsthat could cause actual results to differ from the projected results. All statements, other than statements of historical fact that wemake in this Quarterly Report on Form 10-Q, are forward-looking. The words “anticipates,” “believes,” “expects,”“intends,” “will continue,” “estimates,” “plans,” “projects,” the negativeof these terms and similar expressions are intended to identify forward-looking statements. However, the absence of these words doesnot mean the statement is not forward-looking.

Forward-lookingstatements involve risks, uncertainties or other factors which may cause actual results to differ materially from the future results,performance or achievements expressed or implied by the forward-looking statements. These statements are based on our management’sbeliefs and assumptions, which in turn are based on currently available information. Certain risks, uncertainties or other importantfactors are detailed in this Quarterly Report on Form 10-Q and may be detailed from time to time in other reports we file with the Securitiesand Exchange Commission, including on Forms 8-K and 10-K.

Weoperate in a very competitive and rapidly changing environment. New risks emerge from time to time.

CriticalAccounting Policies

Our condensed financial statements and accompanying notes have been prepared in accordance with U.S. GAAP. The preparation of these financial statements requires management to make estimates, judgments and assumptions that affect reported amounts of assets, liabilities, revenues and expenses. We continually evaluate the accounting policies and estimates used to prepare the condensed financial statements. The estimates are based on historical experience and assumptions believed to be reasonable under current facts and circumstances. Actual amounts and results could differ from these estimates made by management. Certain accounting policies that require significant management estimates and are deemed critical to our results of operations or financial position are discussed in our Annual Report on Form 10-K for the year ended December 31, 2025, and Note 1 to the Condensed and Consolidated Financial Statements in this Form 10-Q.

Accounts Receivable Accounts Receivable and related party notes receivable amounts from sales to various suppliers and online platforms and loans. Accounts receivable are stated at the amount management expects to collect from outstanding balances. Management provides for probable uncollectable amounts through a charge to bad debt expense and a credit to a valuation allowance based on its assessment of the current status of individual accounts. Balances that are still outstanding after management has used reasonable collection efforts are written off through a charge to the valuation allowance and a credit to accounts receivable. A reserve for sales returns and allowances is considered immaterial and, as a result, there was no reserve for sales returns and allowances, at March 31, 2026, and December 31, 2025, respectively.

Item3. Quantitative and Qualitative Disclosures about Market Risk

As a “smaller reporting company” as defined by Item 10 of Regulation S-K, we are not required to provide information required by this item.

Item4. Controls and Procedures

Disclosure of controls and procedures.

The Company is responsible for establishing and maintaining adequate internal control over financial reporting in accordance with the Rule 13a-15 of the Securities Exchange Act of 1934. The Company’s officer, its president, conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of March 31, 2026 based on the criteria establish in Internal Control Integrated Framework issued by the 2013 Committee of Sponsoring Organizations of the Treadway Commission. Based on the foregoing evaluation, we concluded that our disclosure controls and procedures were not effective as of March 31, 2026 and were not effective to ensure that information required to be disclosed by the Company in reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified by SEC rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is accumulated and communicated to the Company’s management, including its Chief Executive and Principal Accounting & Financial Officers as appropriate to allow timely decisions regarding required disclosure.

The material weaknesses relate to the following:

●	We<br> do not have adequate segregation of duties in the handling of our financial reporting. This is caused by a very limited number of<br> personnel.
●	Our<br> accounting staff does not have sufficient technical accounting knowledge relating to accounting for income taxes and complex US GAAP<br> matters.
●	The<br> Company has not performed a risk assessment and mapped our process to control objectives.
●	The<br> Company has not implemented comprehensive entity-level internal controls.
●	The<br> Company has not implemented adequate system and manual controls.

| 21 |

| --- |

Plan for Remediation of Material Weaknesses

We intend to take appropriate and reasonable steps to make the necessary improvements to remediate this deficiency as resources to do so become available. We intend to consider the results of our remediation efforts and related testing as part of our year-end 2026 assessment of the effectiveness of our internal control over financial reporting.

Such remediation would entail enhancing the training and oversight of the accounting personnel responsible for non-routine transactions involving complex accounting matters and engaging the services of an independent consultant with sufficient expertise in income tax and complex U.S. GAAP matters to assist us in the preparation of our financial statements.

Management believes that the aforementioned material weaknesses did not impact our financial reporting or result in a material misstatement of our condensed financial statements.

Changes in internal controls over financial reporting.

There were no changes in our internal control over financial reporting that occurred during the period covered by this Quarterly Report on Form 10-Q that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
