CAPSTONE HOLDING CORP.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 Nature of Operations

Capstone Holding Corp. (the “Capstone”) is a holding company and its operations consist substantially of the operations of its consolidated subsidiary, TotalStone, LLC (“TotalStone”). On April 1, 2020, Capstone obtained controlling interest in TotalStone, a materials distribution company that distributes masonry stone products for residential and commercial construction in the Midwest and Northeast United States under the trade names Instone and Northeast Masonry Distributors (“NMD”). On August 22, 2025, Capstone purchased all of the issued and outstanding membership interests (the “Holdings Membership Interests”) in Carolina Stone Holdings, LLC (“Carolina Stone Holdings”), which owns all of the issued and outstanding membership interests of Carolina Stone Distributors, LLC. Carolina Stone Holdings is a stone supplier and installer specializing in both manufactured and natural stone veneer and offering end-to-end services, including material supply, installation, and project management for residential, commercial, and multi-family projects.

Note 2 IPO and Restructuring

On March 7, 2025 (the “Restructuring Date”), Capstone closed its Public Offering of 1,250,000 shares of common stock (the “Public Offering Shares”), which were registered under the Rule 424(b) of the Securities Act of 1933, as amended, pursuant to the Registration Statement on Form S-1 (File No. 333-284105) which was declared effective by the SEC on February 14, 2025. The Public Offering Shares were sold at a public offering price of $4.00 per share, which generated net proceeds of approximately $3,252,000 after deducting underwriting discounts and commissions and other offering expenses.

On March 7, 2025, TotalStone entered into a fifth amended and restated limited liability company agreement to govern its operations and affairs and its relationship with its members, which post restructuring is solely Capstone.

On March 10, 2025, TotalStone paid Brookstone Partners IAC, Inc. $200,000 for financial advisory and related services with respect to Capstone’s capital raising transaction as agreed upon in the Restated Management Fee Agreement and Transaction Fee Agreement executed in March 2025.

Outstanding warrants to purchase 1,125 Class A Common Interests in TotalStone were cancelled on the Restructuring Date.

On the Restructuring Date, pursuant to a master exchange agreement (the “Master Exchange Agreement”) entered into by the Capstone, TotalStone and TotalStone’s Class B and Class C Members, all of TotalStone’s Class B and Class C Preferred Interests were exchanged for 3,782,641 shares of Common Stock that constitute approximately 96% of the shares of Common Stock outstanding on the Restructuring Date, which were allocated to the Class B and Class C Members as set forth in the Master Exchange Agreement. As consideration for the issuance of 3,782,641 shares of Common Stock, the Class B and Class C Members surrendered their existing TotalStone’s membership interests and withdrew from the membership of TotalStone. Following the restructuring, BP Peptides, LLC, the owner of approximately 77.3% of Capstone’s shares prior to the restructuring, owns approximately 3% of Capstone’s shares on a post restructuring basis. Following the restructuring, the largest holder of Capstone’s shares (approximately 64%) will be BPA XIV, LLC. BP Peptides, LLC is jointly controlled by Matthew Lipman, our chief executive officer and a member of our board of directors, and Michael Toporek, the chairman of our board of directors, and BPA XIV, LLC is controlled by Mr. Lipman. On the Restructuring Date, the Class C Member cancelled his Class A TS Warrants, and his right to receive incentive compensation from TotalStone. TotalStone’s Class C Preferred Interests were historically included in TotalStone’s Class B Preferred Interests on the Company’s consolidated balance sheet.

TotalStone’s Special Preferred Membership Interests were exchanged on the Restructuring Date for loans in an aggregate principal amount of $1,006,377 plus interest.

In connection with the Restructuring, Capstone also increased its authorized shares of Common Stock to 50,000,000 shares and increased the authorized shares of preferred stock to 25,000,000 shares.

The consolidated balance sheet at December 31, 2024 has been derived from the audited consolidated financial statements at that date but does not include all of the information and notes required by GAAP for complete financial statements. These financial statements have been prepared on a basis that is consistent with the accounting principles applied in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 (“2024 Form 10-K”). This report should be read in conjunction with our 2024 Form 10-K filed with the SEC on March 31, 2025.

In our opinion, the accompanying unaudited interim consolidated financial statements include all normal and recurring adjustments (which consist primarily of accruals, estimates, and assumptions that impact the financial statements) considered necessary to present fairly the Company’s financial position as of ~~June~~September 30, 2025 and its results of operations, cash flows, and changes in stockholders’ deficit for the ~~three~~ three and ~~six~~nine months ended ~~June~~September 30, 2025 and 2024. The results for the three and ~~six~~nine months ending ~~June~~September 30, 2025, are not necessarily indicative of the results expected for any future period or the full year.

Use of Estimates

The preparation of financial statements in accordance with US GAAP requires management to make a number of assumptions and estimates that affect the reported amounts of assets, liabilities, and expenses in our financial statements and accompanying notes. Management bases its estimates on historical experience and various other assumptions believed to be reasonable. Although these estimates are based on management’s assumptions regarding current events and actions that may impact on the Company in the future, actual results may differ from these estimates and assumptions.

Business Combinations

The Company accounts for business acquisitions using the acquisition method of accounting, in accordance with which assets acquired and liabilities assumed are recorded at their respective fair values at the acquisition date. The fair value of the consideration paid, including contingent consideration, is assigned to the assets acquired and liabilities assumed based on their respective fair values. Goodwill represents the excess of the purchase price over the estimated fair values of the assets acquired and liabilities assumed.

The Company’s management exercises significant judgments in determining the fair value of assets acquired and liabilities assumed, as well as intangibles and their estimated useful lives. Fair value and useful life determinations are based on, among other factors, estimates of future expected cash flows and appropriate discount rates used in computing present values. These judgments may materially impact the estimates used in allocating acquisition date fair values to assets acquired and liabilities assumed, as well as the Company’s current and future operating results. Actual results may vary from these estimates which may result in adjustments to goodwill and acquisition date fair values of assets and liabilities during a measurement period or upon a final determination of asset and liability fair values, whichever occurs first. Adjustments to the fair value of assets and liabilities made after the end of the measurement period are recorded within the Company’s operating results.

Accounts Receivable

Accounts receivable are recorded and carried at the original invoiced amount less an allowance for any potential uncollectible amounts. The Company estimates expected credit losses for the allowance for expected credit losses based upon its assessment of various factors, including historical experience, the age of the accounts receivable balances, credit quality of its customers, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect the Company’s ability to collect from customers. As of ~~June~~September 30, ~~2025~~ 2025 and December 31, 2024, the allowance for doubtful accounts totaled approximately $104.0 thousand.

Certain of the Company’s contracts with customers include retainage provisions. Retainage represents amounts withheld from billings by customers until installation work has been inspected to ensure that obligations have been satisfied under the contract. Company invoices retainage and includes it in contract receivables when obligations have been satisfied and the right to receipt is subject only to the passage of time. As of September 30, 2025, retainage receivables were $162.0 thousand. There were no retainage receivables as of December 31, 2024.

Note 3 Summary of Significant Accounting Policies (cont.)

Inventories

Inventories consisting of finished goods are stated at the lower of cost, determined by the average cost method, or net realizable value. Inventories also include deposits placed on inventory purchases for shipments not yet received. Significant prepaid inventory may be located overseas. At ~~June~~September 30, 2025 and December 31, 2024, the total prepaid inventory balance was $~~290~~219.0 thousand and $163.0 thousand, respectively. The reserve for obsolete inventory at ~~June~~September 30, 2025 and December 31, 2024, totaled $~~596~~608.0 and $576.0 thousand, respectively.

Property and Equipment

Property and equipment is stated at cost and is depreciated over the estimated useful lives ranging from three to forty years. Depreciation is computed by using the straight-line method for financial reporting purposes and straight-line and accelerated methods for income tax purposes. Property and equipment is comprised of building, machinery & equipment, computer equipment, leasehold improvements, software, office equipment, vehicles, and furniture & fixtures. Maintenance and repairs are charged to expense as incurred. Depreciation and amortization expense on property and equipment for the three and ~~six~~nine months ended ~~June~~September 30, 2025 and 2024 were $6563.0 and $71.0 thousand and $~~130~~192.0 and $~~139~~209.0 thousand, respectively.

Goodwill and Other Intangible Assets

Goodwill represents costs in excess of fair values assigned to the underlying net assets of acquired businesses. Goodwill and indefinite lived intangible assets are not amortized but rather are tested for impairment annually as of the 1st day of the fourth quarter of each year or more frequently if indications of potential impairment exist. The Company’s goodwill is recognized in ~~one~~two reporting ~~unit~~units, ~~its~~TotalStone ~~consolidated~~and ~~subsidiary,~~Carolina ~~TotalStone~~Stone.

In evaluating potential goodwill impairment, we first assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If, based on a review of qualitative factors, it is more likely than not that the fair value of a reporting unit is less than its carrying value, we perform a quantitative analysis. If the quantitative analysis indicates the carrying value of a reporting unit exceeds its fair value, we measure any goodwill impairment losses as the amount by which the carrying amount of a reporting unit exceeds its fair value, not to exceed the total amount of goodwill allocated to that reporting unit. The Company determined that no impairment was required for the periods presented.

Intangible assets with finite lives, consist of a distribution agreement, customer relationships and non-compete agreements that are amortized over the ~~term~~terms of the ~~agreement~~agreements or expected useful lives.

Long-lived Asset Impairments

Long-lived assets and finite lived identifiable intangibles are reviewed for impairment whenever events of changes in circumstances indicate that the carrying amount of an asset may not be recoverable. Recoverability of the assets is measured by a comparison of the carrying amount of an asset to future undiscounted net cash flows expected to be generated by the asset. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount of which the carrying amount of the assets exceeds the fair value of the assets. The Company determined that no impairment was required for the periods presented.

Convertible Debt

The Company accounts for convertible debt in accordance with ASC 470-20, Debt – Debt with Conversion and Other Options. Convertible debt instruments are evaluated at issuance to determine whether they contain embedded features that require bifurcation as derivatives or equity components. If the embedded conversion feature meets the criteria for derivative accounting under ASC 815, Derivatives and Hedging, it is bifurcated and recorded separately at fair value, with subsequent changes in fair value recognized in earnings. Upon modification, conversion or repurchase of convertible debt, the Company evaluates the potential of a gain or loss in accordance with ASC 470-20 and ASC 470-50, Debt Modifications and Extinguishments.

Shipping and Handling

The Company includes amounts billed to customers related to shipping and handling and shipping and handling expenses in cost of goods sold.

Earnings Per Share

Basic earnings (loss) per share is computed by dividing the net income (loss) applicable to the common stockholders of Capstone Holding Corp. by the weighted average number of shares of common stock outstanding during the year. Diluted earnings (loss) per share is computed by dividing the net income (loss) applicable to common stockholders by the weighted average number of common shares outstanding plus the number of additional common shares that would have been outstanding if all dilutive potential common shares had been issued, using the treasury stock method and the if-converted method for convertible notes. Potential common shares are excluded from the computation when their effect is antidilutive.

For the ~~six~~nine months ended ~~June~~September 30, 2025 and 2024, the calculations of basic and diluted loss per share are the same because potential dilutive securities would have had an anti-dilutive effect. The number of incremental common shares from potentially dilutive securities consisted of the following:

	June 30, 2025		June 30, 2024
	September 30, 2025		September 30, 2024

Note 9 Stockholders’ Equity (cont.)

On June 26, 2025, the Company and the Equity Line Investor entered into a first amendment to the Purchase Agreement (the “First Amendment to Purchase Agreement”), which amended the definition of “VWAP Purchase Maximum Amount” in the Purchase Agreement to (a) remove the volume limitation on the number of Equity Line Securities that may be purchased pursuant to a single VWAP Purchase (as defined in the Purchase Agreement) based on 100% of the five-day average trading volume, and (b) increase the dollar-based limitation on the number of Equity Line Securities that may be purchased pursuant to a single VWAP Purchase from $2 million to $3 million. As amended, the term “VWAP Purchase Maximum Amount” now means the maximum number of Equity Line Securities that can be purchased in a single VWAP Purchase is equal to the lesser of (a) 40% of the trading volume in the Company’s common stock on the relevant exchange on the day the VWAP Purchase is exercised, or (b) $3 million divided by the volume-weighted average price of the common stock on the trading day immediately preceding the date the VWAP Purchase is exercised.

Effective August 14, 2025, the conversion price per share of the Convertible Notes was amended to decrease the conversion price to $1.00 with regard to $1,363,736 of principal of the Convertible Note. The Company evaluated the amendment to the conversion price of the Convertible Notes accordance with ASC 470-50 and concluded that the amendment should be accounted for as a debt 10extinguishment ~~Segment~~because of a substantial change to the conversion feature. ~~Information~~The total fair value of the portion of the Convertible Notes with amendment to the conversion price on the date of the amendment was $1,759,219 which resulted in the recognition of a loss on extinguishment of $652,161 in the Company’s consolidated statement of operations for the three and nine months ended September 30, 2025.

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis provides information that our management believes is relevant to an assessment and understanding of our consolidated results of operations and financial condition. This discussion may contain certain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and is subject to the safe harbor created by those sections. For more information, see “Cautionary Note Regarding Forward-Looking Statements.” When reviewing the discussion below, you should keep in mind the substantial risks and uncertainties that impact our business. In particular, we encourage you to review the risks and uncertainties described in our Annual Report on Form 10-K for the year ended December 31, 2024 and this Quarterly Report on Form 10-Q under the caption “Part II. Item 1A. Risk Factors”. These risks and uncertainties could cause actual results to differ materially from those projected or implied by our forward-looking statements contained in this report. These forward-looking statements are made as of the date of this report, and we do not intend, and do not assume any obligation, to update these forward-looking statements, except as required by law.

The following discussion and analysis should be read in conjunction with our unaudited consolidated financial statements and related notes thereto included in this Quarterly Report and our audited consolidated financial statements and related notes thereto for the year ended December 31, 2024, included in our 2024 Form 10-K. Throughout this discussion, unless the context specifies or implies otherwise the terms the “Company”, “we”, “us” and “our” refer to the business and operations of Capstone Holding Corp and its operating subsidiary, TotalStone, LLC (dba Instone).

All dollar amounts stated herein are in U.S. dollars unless specified otherwise.

Overview

Capstone Holding Corp., formerly known as Capstone Therapeutics Corp. and OrthoLogic Corp., incorporated in Delaware in 1987 as a domestic corporation, is the parent entity of TotalStone, LLC (dba Instone). Instone has a building products distribution network that services 31 US states (with such states having over 60% of American households). Our over 400 active customers are primarily masonry, building materials and landscape dealers.

Through TotalStone, the Company also operates Carolina Stone Products, a distributor and installer of stone and masonry products serving the Southeastern United States. From two strategic locations in Raleigh and Charlotte, North Carolina, Carolina Stone Products provides showroom, warehouse, and staging-yard capabilities that support both direct-to-builder installations and distribution to regional dealers. The addition of Carolina Stone Products enhances Instone’s service capacity, extends our geographic coverage, and strengthens relationships with builders and distributors in a growing regional market.

Historically, the product mix for Instone was heavily concentrated on Cultured Stone®, in 2018 Cultured Stone® comprised almost 80% of our total revenue. Through acquisition and product expansions, we have increased our product offering to our customers. This expansion has made Instone a more attractive supplier to new and existing dealers.

We provide value to our dealers by making the procurement and logistics process easy for product lines that are otherwise challenging for dealers to manage if they were to purchase directly with a manufacturer or quarry. Our website provides efficiency, and we believe our product offering provides options and ability for vendor consolidation and our logistical capabilities provide cost effective and efficient delivery, typically within a week or less.

A key differentiating factor for our strategy is that we own or control five of the eight brands we sell. Our products include stone veneer, landscape stone, and modular masonry fireplaces. The brands we distribute which we do not control are Cultured Stone®, Dutch Quality®, and Isokern®. The brands we distribute which we own or control include Aura™, Pangea Stone®, Toro Stone™, Beon Stone®, and Interloc™.

We operate in a market environment where there are about 7,000 building products dealers, most of which are privately held. Many of these dealers are not able to efficiently purchase or optimize storage space, which constrains their ability to sell the diverse range of products we offer. Our website enables dealers to buy in the quantities they require thus driving a more optimal level of inventory while also significantly reducing logistical challenges. We believe the ability for customers to buy in the quantities they need across many product lines instead of buying single product lines form different manufacturers helps them manage cash and, in turn, allows them to offer a higher level of service to their own customers.

We intend to continue to grow our business organically and through successfully integrating well-timed acquisitions.

Recent Developments

On March 7, 2025, the Company closed its public offering (the “March 2025 Public Offering”) of 1,250,000 shares of common stock (the “Public Offering Shares”), which were registered under the Rule 424(b) of the Securities Act of 1933, as amended, pursuant to the Registration Statement on Form S-1 (File No. 333-284105) which was declared effective by the SEC on February 14, 2025.

Sales

Sales were $2034.74 million for the ~~six~~nine months ended ~~June~~September 30, 2025 compared to $2234.26 million for the ~~six~~nine months ended ~~June~~September 30, 2024. Revenue decreased between the ~~six~~ nine months ended ~~June~~ September 30, 2025 and 2024 by $1158.50 ~~million~~thousand.

Sales decreased in 2025 due to colder winter temperatures experienced when compared to prior year, along with challenging economic conditions attributable to trade policies, interest rates, and concerns about inflation.

The majority of the decline was driven by lower volumes in our veneer products resulting in $2.4 million in lower revenues; offset by an increase in our landscaping products of $760.0 thousand.

We continue to evaluate the potential impact of tariffs and have successfully transitioned the sourcing of higher volume products from China to other parts of the world. We believe the actions taken will minimize the impact of tariffs on our customers and end users.

Cost of goods sold

Cost of goods sold decreased by $1366.40 ~~million~~thousand, or 81%, for the ~~six~~nine months ended ~~June~~September 30, 2025 compared to the ~~six~~nine months ended ~~June~~September 30, 2024.

The decrease in cost of goods sold was driven primarily by product mix, lower outbound freight, and lower landed cost goods.

Gross profit margin increased from 20.3% for the six months ended June 30, 2024 to 21.5% for the six months ended June 30, 2025. The increase in gross profit margin was primarily driven by product mix, lower outbound freight, and lower landed cost goods.

Interest expense

Interest expense increased by $186.0 thousand, or 16%, for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. The increase is largely attributed to the amortization of debt costs related to our Senior Convertible Note.

The above discussion of consolidated operating results through operating income (loss) is in substance the operating results of TotalStone for the comparable periods presented. The elimination of selling, general and administrative expenses reflect the elimination of management fees incurred by TotalStone and earned by ~~Parent~~the Company. The ~~Parent~~Company classifies the management fee income earned as a component of net non-operating income (expense) and the corresponding income is also eliminated in the Company’s consolidated results.

Liquidity and Capital Resources

Working capital excluding the current portion of long-term debt was $2.58 million and $2.1 million as of ~~June~~September 30, 2025 and December 31, 2024, respectively. The $~~400~~700.0 thousand ~~increase~~ increase in working capital is primarily attributable to an increase in accounts receivable, inventory and cash; offset by accounts payable and an increase in our revolving line of credit.

The Company primarily funds our operations through cash provided from operations of our building products distribution network and available capacity under our ABL Facility (“Revolver”). Our operating cash flows fluctuate based on seasonality with the first quarter typically a slower period in our calendar year resulting in negative operating cash flows from the building of accounts receivables and inventory levels. During the second half of the year we generate positive operating cash flows as we bring down accounts receivables and inventory levels from seasonal high periods and pay down our Revolver.

In 2024 the Company was not in compliance with certain of the Revolver’s financial covenants which have been waived by our lender. As of June 30, 2025, the Company was in compliance with the Revolver’s financial covenant as of the issuance date of these interim consolidated financial statements. In June 2025, the Company executed an amendment to the Revolver that extended the maturity date from April 2025 to December 2025. The Company believes the Revolver will continue to be available and the longer-term extension will be executed with financial covenants aligned to the Company’s anticipated future results.22

~~The~~In ~~liquidity~~2024, of the Company iswas ~~largely~~not ~~dependent on~~in ~~our~~compliance ~~ability~~with certain ~~to borrow funds on our Revolver. The longer-term extension~~ of the Revolver’s ~~and~~financial ~~future~~covenants ~~compliance~~which ~~with~~have ~~financial~~been ~~covenants are~~waived ~~subject~~by toour ~~risks~~lender. ~~and~~As ~~uncertainties~~of ~~which~~September ~~could~~30, ~~have~~2025, athe ~~material~~Company ~~adverse~~was ~~effect~~in compliance onwith ~~our~~the ~~business,~~Revolver’s financial ~~condition~~covenant ~~and~~as ~~results~~ of ~~operations.~~ ~~The~~the ~~Company~~issuance ~~currently~~date ~~believes~~of ~~that~~these itinterim ~~will~~consolidated ~~have~~financial ~~sufficient~~statements. ~~working~~In June ~~capital~~2025, tothe ~~operate~~Company ~~for~~executed aan ~~period~~amendment ofto atthe ~~least~~Revolver ~~one~~that ~~year~~extended ~~from~~ the ~~issuance~~maturity date offrom ~~the~~April ~~June~~2025 ~~30,~~to December 2025. ~~interim~~The ~~consolidated~~Company believes ~~financial~~the ~~statements~~Revolver ~~based~~will oncontinue ~~future~~to ~~expected~~be ~~results.~~available ~~Future~~and ~~acquisitions may~~the belonger-term ~~financed~~extension ~~through~~will ~~other~~be ~~forms~~executed ofwith ~~financing~~financial ~~that~~covenants ~~will~~aligned ~~depend~~to the onCompany’s ~~existing~~anticipated ~~conditions~~future results.

The liquidity of the Company is largely dependent on our ability to borrow funds on our Revolver. The longer-term extension of the Revolver and future compliance with financial covenants are subject to risks and uncertainties which could have a material adverse effect on our business, financial condition and results of operations. The Company currently believes that it will have sufficient working capital to operate for a period of at least one year from the issuance date of the September 30, 2025 interim consolidated financial statements based on future expected results. Future acquisitions may be financed through other forms of financing that will depend on existing conditions.

Seasonality

The Company historically experiences higher sales during our second and third quarters due to the favorable weather in the Midwestern and Northeastern United States for new construction and remodeling.

Net cash used in by financing activities was $1.0 million for the nine months ended September 30, 2024. The cash out was primarily related to the repayment of term debt of $750.0 thousand.

Funding Requirements

We currently expect to use some of the net proceeds of our March 2025 Public Offering primarily for organic growth, by expanding the breadth of our distribution network by both geography and new products, and inorganic growth via rapid acquisition program of building products distributors and manufacturers whose distribution core can be fortified to expand their footprint.

The Company, as described in Note 910 to the consolidated financials statements included in this Quarterly Report and in the Recent Developments section of this Management’s Discussion and Analysis, received $36,250,000 ~~million~~ in gross proceeds pursuant to the Convertible Note Financing. In addition, as described in Note 45, the Company may receive up to $20.0 million from the sale of the Equity Line Securities to the Equity Line Investor. The Company plans to raise additional funds to finance the growth of our operations through equity financing or debt financing arrangements. If we raise additional funds by issuing equity or equity-linked securities, the ownership of our existing stockholders will be diluted.

Off-Balance Sheet Arrangements

During the periods presented we did not have, and we do not currently have, any off-balance sheet arrangements, as defined in the rules and regulations of the SEC.

Critical Accounting Policies and Significant Judgments and Estimates

The Critical Accounting Policies and Significant Judgments and Estimates included in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 31, 2025, have not materially changed. For the quarter ended September 30, 2025, we added the following two critical accounting policies and Significant Judgments and Estimates to Note 3 in the footnotes to the consolidated financial statements: Business Combinations and Convertible Notes.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Not applicable.

ITEM 4. CONTROLS AND PROCEDURES

Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as that term is defined in Rule 13a-15(e), promulgated by the SEC pursuant to the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed in our Company’s reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer to allow timely decisions regarding required disclosure. Our management, with the participation of our principal executive officer and principal financial officer, evaluated our Company’s disclosure controls and procedures as of the end of the period covered by this Form 10-Q. Based on this evaluation, our principal executive officer and principal financial officer concluded that as of ~~June~~September 30, 2025, our disclosure controls and procedures were not effective. The ineffectiveness of our ~~disclosure~~ disclosure controls and procedures was due to the following material weaknesses in our internal control over financial reporting.

Due to accounting resource constraints, we have had limited review controls. These constraints have resulted in (1) a lack of segregation of duties, since we have a limited administrative staff, and (2) lack of internal controls structure review.

Our management is composed of a small number of individuals resulting in a situation where limitations on segregation of duties exist. All responsibility for accounting entries and the creation of financial statements has historically been held primarily by a single person, though the Company engages multiple accounting consultants for accounting, tax and audit support. In April 2025, the Company hired a controller.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal controls over financial reporting, as defined in Rules 13a-15(f) of the Exchange Act, during the quarter ended ~~June~~September 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting

PART II

ITEM 1. LEGAL PROCEEDINGS

From time to time, we may be engaged in various lawsuits and legal proceedings in the ordinary course of our business. We are currently not aware of any legal proceedings the ultimate outcome of which, in our judgment based on information currently available, would have a material adverse effect on our business, financial condition or results of operations.

ITEM 1A: RISK FACTORS

For information regarding the risk factors that could affect the Company’s business, results of operations, financial condition and liquidity, see the information under Part I, Item 1A. “Risk Factors” in the Form 10-K, which is accessible on the SEC’s website at www.sec.gov. There have been no material changes to the risk factors previously disclosed in the Form 10-K.

ITEM 2: UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

During the three months ended ~~June~~September 30, 2025, there have been no unregistered sales of equity securities that have not been previously disclosed in a Current Report on Form 8-K.

ITEM 3: DEFAULTS UPON SENIOR SECURITIES.

None.

ITEM 4. MINE SAFETY DISCLOSURES

Not applicable.

ITEM 5: OTHER INFORMATION.

Insider trading arrangements and policies.

During the quarter ended ~~June~~ September 30, 2025, no director or officer of the Company adopted or terminated any “Rule 10b5-1 trading arrangement” or “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K.
