On April 1, 2020, the Company obtained a controlling interest in TotalStone, a materials distribution company that distributes masonry and stone veneer products for residential and commercial construction across the United States. TotalStone operates under the trade names Instone and Northeast Masonry Distributors ("NMD").

On August 22, 2025, the Company, through its subsidiary CS Purchase Holdings LLC, acquired all the issued and outstanding membership interests (the "Holdings Membership Interests") in Carolina Stone Holdings, which owns all the issued and outstanding membership interests of Carolina Stone Distributors, LLC. Carolina Stone 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 in the Raleigh-Durham and Charlotte, North Carolina markets.

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 $1,143,646 (representing $1,006,377 of original principal plus $137,269 of accrued 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 3 Summary of Significant Accounting Policies

Basis of Presentation and Preparation

The ~~accompanying~~ consolidated financial statements include the accounts of Capstone and its consolidated subsidiaries (collectively, the “Company”). Intercompany accounts and transactions have been eliminated. ~~Prior-year~~The ~~amounts~~preparation ~~may~~of ~~include~~these ~~instances~~financial statements and accompanying notes is in accordance with accounting principles generally accepted in the United States of ~~changes~~America. toIn ~~prior-year~~the ~~amounts~~opinion toof ~~achieve~~management, ~~comparability to~~the financial statements include all adjustments necessary for the ~~most~~fair ~~recent~~presentation ~~fiscal~~of ~~year~~our financial position, results of operations, and cash flows, and all adjustments were of a normal recurring nature.

The accompanying unaudited interim consolidated financial statements have been prepared in accordance with GAAP for interim financial information and with the rules and regulations for reporting the Quarterly Report on Form 10-Q (“Form 10-Q”). Accordingly, they do not include all of the information and notes required by GAAP for annual consolidated financial statements.

The consolidated balance sheet at on December 31, ~~2024~~2025 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 on December 31, ~~2024~~ 2025 (“~~2024~~2025 Form 10-K”). This report should be read in conjunction with our ~~2024~~ 2025 Form 10-K filed with the SEC on April ~~March~~16, 312026, ~~2025~~as amended on April 17, 2026.

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 March ~~September 30~~31, ~~2025~~ 2026 and its results of operations, cash flows, and changes in stockholders’ Equity (deficit ) for the three ~~and nine~~ months ended ~~September 30~~ March 31, ~~2025~~ 2026 and ~~2024~~ 2025. The results for the three ~~and~~ ~~nine~~ months ~~ending September 30~~ ended March 31, ~~2025~~ 2026, 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 asome ~~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~~ the estimated fair values of the assets acquired and liabilities assumed at acquisition date.

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.

Fair Value Measurements

The Company measures certain assets and liabilities at fair value in accordance with ASC 820, Fair Value Measurement. ASC 820 defines fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. ASC 820 establishes a three-level hierarchy that prioritizes the inputs used in measuring fair value at the date of acquisition:

Level 1 — Quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

Level 2 — Inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, and inputs that are derived principally from or corroborated by observable market data.

Level 3 — Unobservable inputs for the asset or liability that are supported by little or no market activity and that are significant to the fair value measurement. Level 3 inputs reflect the Company's own assumptions about the assumptions market participants would use in pricing an asset or liability, developed based on the best information available in the circumstances.

The categorization of an asset or liability within the hierarchy is based on the lowest level of input that is significant to the fair value measurement. Transfers between levels are recognized at the end of the reporting period in which the transfer occurs.

The Company's recurring fair value measurements as of March 31, 2026 consist of (i) the embedded conversion features bifurcated from the Senior Secured Convertible Notes, classified as derivative liabilities and measured at fair value using significant unobservable inputs (Level 3); and (ii) the contingent earn-out consideration related to the Carolina Stone and Fraser Canyon acquisitions, measured at fair value using a probability-weighted discounted cash flow model with significant unobservable inputs (Level 3). The Company also performs nonrecurring fair value measurements in connection with business combinations (Note 4) and goodwill impairment testing (Note 7), which involve Level 3 inputs including projected cash flows, discount rates, and market multiples. The Company has no recurring Level 1 or Level 2 fair value measurements as of March 31, 2026 or December 31, 2025.

Cash

Cash consists of balances held in a commercial bank account.

Accounts Receivable

Accounts ~~receivable~~receivables 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 March ~~September 30~~31, ~~2025~~ 2026 and December 31, ~~2024~~2025, the allowance for doubtful accounts totaled approximately $~~104~~135.0 and $127.0 thousand, respectively.

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~~are retained and ~~includes it~~ included in contract receivables when obligations have been satisfied and the right to receipt is subject only to the passage of time. As of March ~~September~~31, 302026 and December 31, 2025, retainage receivables were $~~162~~15.0 thousand. ~~There were no retainage receivables as of December 31, 2024.~~

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash and trade accounts receivable. The Company places cash with high credit quality institutions. During the normal course of business, balances in these accounts may exceed the maximum amount insured by the Federal Deposit Insurance Corporation (“FDIC”). Concentrations of credit risk with respect to accounts receivable are limited due to the large number of customers comprising the Company’s diverse customer base and generally short payment terms. Management believes there is no business vulnerability regarding concentrations of accounts receivable and sales due to the strong relationships and financial strength of our customers.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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 March ~~September~~31, 302026, the ~~2025~~Company ~~and~~did not have a prepaid inventory balance. At December 31, ~~2024~~ 2025, the total prepaid inventory balance was $~~219~~61.0 thousand ~~and $163~~.0 ~~thousand, respectively.~~ The reserve for obsolete inventory at ~~September 30~~ March 31, ~~2025~~ 2026 and December 31, ~~2024~~2025, totaled $~~608~~840.0 and $~~576~~793.0 thousand, respectively.

Property and Equipment

Property and equipment isare 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~~Minor maintenance and repairs are charged to expense as incurred. Depreciation and amortization expense on property and equipment for the three and nine months ended September 30, 2025 and 2024 were $63.0 and $71.0 thousand and $192.0 and $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~~allocated into ~~two~~the Company’s reporting units for impairment assessment purposes. As of March 31, 2026, the Company has three reporting units: TotalStone (TotalStone, LLC), Canadian Stone Industries (Fraser Canyon Holdings Inc.), and Carolina Stone (Carolina Stone Distributors, LLC). The Company aggregates TotalStone and Canadian Stone Industries into a single reportable segment for ASC 280 segment-reporting purposes (see Note 18).

In evaluating potential goodwill impairment, we the Company first ~~assess~~assesses 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, wethe ~~perform~~Company performs a quantitative analysis. If the quantitative analysis indicates the carrying value of a reporting unit exceeds its fair value, wethe ~~measure~~Company measures any goodwill impairment ~~losses~~loss 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.~~

During the year ended December 31, 2025, the Company performed a quantitative goodwill impairment test for the Instone reporting unit as of October 1, 2025, and recorded a goodwill impairment charge of $6.2 million. See Note 7 for additional information regarding the Company's goodwill impairment testing. As of March 31, 2026, the Company concluded no goodwill impairment was required.

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

Convertible Debt

The Company accounts for convertible debt in accordance with ASC 470-20, ~~Debt~~ – Debt with Conversion and Other Options., ~~Convertible~~and ~~debt~~ASC ~~instruments~~815, ~~are~~Derivatives ~~evaluated~~and atHedging. At issuance, tothe ~~determine whether~~Company ~~they~~evaluates ~~contain~~whether embedded conversion features ~~that~~ require bifurcation as ~~derivatives~~derivative orliabilities ~~equity~~under ~~components~~ASC 815-15.

Revenue Recognition

Our sales primarily consist of distributing manufactured and natural stone cladding products, natural stone landscape products, and related goods for residential and commercial construction through a dealer network in 3238 states ~~in the Midwestern, Northeastern~~ and ~~Southeastern~~two ~~United~~Canadian ~~States~~provinces. For distribution sales, the Company recognizes revenue when control over the products has been transferred to the customer, typically upon shipment, and the Company has a present right to payment. For installation and project-based work, the Company recognizes revenue over time as performance obligations are satisfied. For production and custom residential jobs, revenue is generally recognized upon completion, as substantially all projects are short-term in nature. A small portion of commercial projects are recognized based on progress toward percentage of completion, typically through monthly billings. For the three months ended March 31, 2026 and 2025, there are no estimates of variable consideration represented in revenue. Net revenue recognized at a point in time totaled approximately $10.2 million and $7.9 million for the three months ended March 31, 2026 and 2025, respectively. Net revenue recognized over time totaled approximately $2.4 Million for the three months ended March 31, 2026 and primarily relates to Carolina Stone.

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.

Advertising Costs

Advertising and promotional expenses are expensed in the period incurred unless there are material costs that benefit future periods. The consolidated financial statements currently do not reflect any prepaid advertising expenses. For the three months ended March 31, 2026 and 2025, advertising expenses were $28.0 thousand and $15.0 thousand, respectively.

Research and Development

Research and development costs are expensed as incurred and were not significant in the periods presented.

Mandatorily Redeemable Preferred Stock

The Company classifies preferred stock that embodies an unconditional obligation to redeem the instrument by transferring assets at a specified or determinable date as a liability in accordance with ASC 480, Distinguishing Liabilities from Equity. Such instruments are initially measured at fair value and subsequently measured at the present value of the amount to be paid at settlement, with interest expense accrued using the rate implicit at inception. Periodic dividend obligations on mandatorily redeemable preferred stock classified as a liability are presented as interest expense in the consolidated statements of operations. The Company's Series Z 8% Non-Convertible Preferred Stock, issued September 30, 2025, has been assessed as mandatorily redeemable and is presented as a liability in the accompanying consolidated balance sheets. See Note 15 for additional information.

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. Warrants issued with a nominal exercise price of $0.01 per share are considered common stock equivalents and are included in the weighted-average number of common shares outstanding used to compute basic earnings (loss) per share.

For the ~~nine~~three months ended March ~~September 30~~31, ~~2025~~2026 and ~~2024~~ 2025, the calculations of basic and diluted loss per share are the same because potential dilutive securities would have had an anti-dilutive effect. ~~The~~For the three months ended March 31, 2026 and 2025, the number of incremental common shares from potentially dilutive securities consisted of the following:

The Company has 120 days from closing to complete the final calculation of the net working capital adjustment, after which any required payment or adjustment will be made pursuant to the terms of the Acquisition agreement. The Company has retained the working capital holdback amount of $201,500 which is accrued in current liabilities on the consolidated balance sheet as of September 30, 2025.

Carolina Stone Distributors, LLC

On August 22, 2025, the Company, through its subsidiary CS Purchase Holdings LLC, completed its acquisition of all the issued and outstanding 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”). Carolina Stone is a Morrisville, North Carolina-based distributor and installer of stone veneer and masonry products serving the Raleigh-Durham and Charlotte metropolitan areas.

Purchase Consideration. The aggregate purchase consideration for the Carolina Stone Companies was approximately $4,202.0 thousand, consisting of the following: cash at closing of $2,625.0 thousand (less preliminary working capital adjustment of $124.0 thousand for net cash transferred of $2,501.0 thousand), a subordinated promissory note of $1,250.0 thousand, final working capital adjustment of $77.0 thousand, and contingent consideration (earn-out) at fair value of $250.0 thousand.

The subordinated promissory note was issued to D22L, Inc. in the original principal amount of $1,250 thousand, maturing February 22, 2028. The note bears interest at SOFR plus 1.25%, payable quarterly commencing December 31, 2025, with quarterly principal payments of $100.0 thousand beginning December 31, 2026. After application of the working capital true-up of approximately $56.0 thousand, the outstanding principal balance at closing was approximately $1,306.0 thousand.

Contingent consideration of up to $825.0 thousand is payable as a singular payment based on Carolina Stone’s EBITDA performance during three annual measurement periods (fiscal years 2025, 2026, and 2027). Only one payment can be earned across all three periods. If Carolina Stone achieves EBITDA of at least $1,000 thousand in either the first or second measurement period, the seller receives the full $825 thousand, payable in equal quarterly installments through June 30, 2028. If the EBITDA threshold is not met in the first two periods, the seller may receive up to $825.0 thousand in the third measurement period if the full amount if EBITDA exceeds $1,000 thousand, or a pro-rata amount determined by linear interpolation if EBITDA falls between $800.0 thousand and $1,000.0 thousand (as the value that EBITDA represents between $775.0 thousand and $1,000.0 thousand). If EBITDA does not reach $800.0 thousand in any measurement period, no earn-out is payable. Based on Carolina Stone's audited financial results for the year ended December 31, 2025, the EBITDA threshold of $1,000 thousand was not achieved for the First Earn-out Period, and accordingly no Earn-Out Payment is payable in respect of the First Earn-out Period.

The fair value of contingent consideration at acquisition date of $250.0 thousand was estimated using a Monte Carlo simulation model with key assumptions including asset volatility of 35.0%, risk-free rate of 3.69%, and EBITDA projections based on management forecasts. Based on management’s assessment as of March 31, 2026 and December 31, 2025, no significant remeasurement of the contingent consideration fair value was required for the three months ended March 31, 2026.

On December 1, 2025, the Company completed the acquisition of Fraser Canyon Holdings Inc. (“FCHI”) and its subsidiaries, including Canadian Stone Industries Inc. (“CSI”), through two simultaneous transactions: (i) TotalStone, LLC acquired substantially all of the assets and assumed certain liabilities of Continental Stone Industries, Inc. (the “Asset Purchase”), and (ii) a subsidiary of TotalStone acquired all of the outstanding shares of FCHI (the “Share Purchase”). CSI is a Langley, British Columbia-based distributor of manufactured and natural stone products serving Western and Eastern Canada.

Purchase Consideration. The Fraser Canyon Acquisition comprises two simultaneous transactions: (i) the CSIA Asset Purchase, in which TotalStone, LLC acquired substantially all of the assets and assumed certain liabilities of Continental Stone Industries, Inc. for cash consideration of approximately US$459.0 thousand (CAD $647.0 thousand); and (ii) the FCHI Share Purchase, in which Instone Canada Corp., a wholly-owned subsidiary of TotalStone, acquired all of the outstanding shares of Fraser Canyon Holdings Inc. for consideration of approximately US$6,267 thousand (representing the FCHI Share Purchase portion of the combined transaction). Under ASC 805, both transactions have been accounted for as a single combined business combination because they were entered into in contemplation of one another and effected concurrently. The purchase consideration for the combined Fraser Canyon Acquisition consisted of: (i) C$6,200,000 in cash (approximately US$4,447 thousand at the closing-day exchange rate of US$1.00 = C$1.3943), of which US$459.0 thousand (C$647 thousand) represented the Continental Cash Purchase Price paid by TotalStone, LLC for the CSIA Asset Purchase, reduced by a working capital adjustment of C$473,189 (approximately US$339.0 thousand) that lowered the Cash Purchase Price payable to the FCHI sellers; (ii) Seller Note I in the principal amount of C$1,600,000 (approximately US$1,148.0 thousand), maturing March 31, 2027; (iii) Seller Note II in the principal amount of C$2,000,000 (approximately US$1,434.0 thousand), maturing December 1, 2028; and (iv) contingent earn-out consideration of up to C$3,000,000 (approximately US$2,152.0 thousand) based on Average EBITDA during the 2026–2027 and 2027–2028 measurement periods, with an acquisition-date fair value of US$100 thousand (US$80.0 thousand for Earn-Out Provision I and US$20.0 thousand for Earn-Out Provision II) as measured with the assistance of Loop Capital and reflected in the purchase price allocation set forth below. The seller notes, working capital adjustment, and earn-out provisions relate solely to the FCHI Share Purchase. U.S. dollar amounts have been translated from Canadian dollars at the closing-day exchange rate of US$1.00 = C$1.3943. The purchase price is subject to finalization during the measurement period.

The Company engaged Loop Capital to assist with the valuation of identifiable intangible assets and contingent consideration; the purchase price allocation presented below is based on valuations performed with the assistance of Loop Capital. The Company will finalize the purchase price allocation within the measurement period. The purchase price allocation is based on management’s best estimates and is subject to adjustment during the measurement period (up to one year from the acquisition date) as additional information is obtained about facts and circumstances that existed at the acquisition date. The aggregate purchase consideration of approximately US$6,262.0 thousand reflected in the purchase price allocation below represents the FCHI Share Purchase only, stated net of the Continental Cash Purchase Price paid separately for the CSIA Asset Purchase and net of the working capital reduction described above, with U.S. dollar amounts translated at the exchange rates used for purchase accounting purposes.

Goodwill totaled approximately US$617 thousand and US$616 thousand at March 31, 2026 and December 31, 2025 (compared to US$601.0 thousand at the acquisition date), including approximately $16.0 thousand and $15.0 thousand of foreign currency translation impact, respectively. Of the goodwill recognized at the acquisition date, $601.0 thousand was recognized in connection with the FCHI Share Purchase, attributable to the assembled workforce (valued at approximately US$230.0 thousand) and expected synergies from integrating Canadian Stone Industries’ western Canadian distribution operations with the Company’s existing platform. Goodwill from the FCHI Share Purchase is not deductible for Canadian income tax purposes. The CSIA Asset Purchase did not result in goodwill, as the cash purchase consideration approximated the fair value of the net assets acquired; any tax basis in goodwill from the CSIA Asset Purchase is amortizable for U.S. income tax purposes pursuant to Section 197 of the Internal Revenue Code. Goodwill recognized in connection with the Fraser Canyon acquisition is allocated to the TotalStone reporting unit.

CSI contributed revenue of $592.0 thousand and net loss of $92.0 thousand for the period from December 1, 2025 through December 31, 2025. For the three months ended March 31, 2026, CSI contributed revenue of $2.5 million and a net loss of $292.0 thousand to the Company's consolidated results. Acquisition-related costs, including the Nectarine consent fee of $89.0 thousand and legal and advisory fees, were expensed as incurred.

Pro Forma Financial Information

The following unaudited pro forma information presents the Company’s consolidated results of operations for the three months ended March 31, 2026 and 2025 as though both acquisitions had been completed as of January 1, 2025:

	*Three Months Ended*
	*March 31,*
	*2026*			*2025*
Revenue	$	12,636		$	13,751
Net income (loss)		(1,915	)		(1,503	)
Earnings (loss) per common share:		(0.21	)		(0.29	)

The Company prepared this unaudited pro forma information under ASC 805-10-50-2(h), presenting consolidated results as if the Carolina Stone Holdings acquisition and the Fraser Canyon acquisition had closed on January 1, 2025. Pro forma earnings per share uses the Company's actual weighted-average common shares outstanding — 9,329,828 for the three months ended March 31, 2026 and 5,190,251 for the three months ended March 31, 2025 — because neither acquisition involved share consideration.

The pro forma results include the following adjustments directly attributable to the acquisitions, consistent with the Company's prior pro forma disclosures in Forms 8-K/A filed with the SEC:

(a) Acquisition-related transaction expenses — Under the assumed acquisition date of January 1, 2025, $99 thousand of acquisition-related transaction expenses recorded in the three months ended March 31, 2026 is excluded from pro forma 2026 results because all transaction-related costs would have been incurred prior to the comparative period.

(b) Incremental amortization expense —$32 thousand for the three months ended March 31, 2025, on the identifiable intangible assets recognized in the finalized purchase price allocations for the Carolina Stone acquisition (trade names of $670 thousand amortized over 20 years; customer relationships of $740 thousand amortized over 12 years; and non-compete agreements of $60 thousand amortized over 5 years) and the Fraser Canyon acquisition (trade names of $190 thousand amortized over 20 years and customer relationships of $170 thousand amortized over 17 years). For the three months ended March 31, 2026, the related amortization expense is already reflected in reported results.

(c) Income taxes — No incremental tax effect has been recognized on Carolina Stone or other U.S.-jurisdiction pro forma adjustments because the Company maintains a full valuation allowance against its U.S. net deferred tax assets. Canadian income tax effects on the Fraser Canyon-related pro forma adjustments are not material to the pro forma presentation and have not been separately reflected.

The pro forma results do not represent what the Company would have reported had the acquisitions closed on the assumed date, nor do they predict future performance.

In December 2022, TotalStone sold its facility in Navarre, Ohio to a nonaffiliated third party for a purchase price of $3.2 million and concurrently entered into a leaseback transaction. The transaction is treated as a failed sale in accordance with U.S. GAAP. The Company therefore recorded a financing liability related to the sale-leaseback in the amount of the sale price.

During the year ended December 31, 2025, the Company engaged Loop Capital and performed a quantitative goodwill impairment test for the Instone reporting unit as of October 1, 2025. The estimated fair value of the reporting unit was determined using a weighted blend of the income approach (discounted cash flow method, 50% weight), the guideline public company method (25% weight), and the guideline merged and acquired company method (25% weight). The blended enterprise value of approximately $28,148.0 thousand, after adjustment for net debt of approximately $14,632.0 thousand, resulted in an estimated fair value of equity of $13,516.0 thousand, which was $6.2 million (31.4%) below the carrying value of $19.7 million. Accordingly, the Company recorded a goodwill impairment charge of $6.2 million during the fourth quarter of 2025. Following the impairment charge, goodwill allocated to the Instone reporting unit was $17.1 million as of December 31, 2025.

Note 8 Fair Value Measurements

The Company’s fair value hierarchy policy is described in Note 3. There were no material changes in the carrying amount of goodwill between December 31, 2025 and March 31, 2026.The following table presents assets and liabilities measured at fair value by level:

At March 31, 2026, the Company’s Level 3 recurring fair value measurements consisted of derivative liabilities of $197 thousand (down from $702.0 thousand at December 31, 2025, principally due to derecognition upon convertible note conversions during the period) and earn-out payable of $352.0 thousand (unchanged from December 31, 2025). The non-recurring Level 3 measurement of goodwill — Instone reporting unit was $17,086.0 thousand at both March 31, 2026 and December 31, 2025; no triggering events for interim impairment testing were identified during the three months ended March 31, 2026. The goodwill of each of the Company's three reporting units - TotalStone (Instone), Canadian Stone Industries, and Carolina Stone - is evaluated for impairment at least annually, or more frequently if impairment indicators arise. Goodwill of the Canadian Stone Industries reporting unit ($617.0 thousand at March 31, 2026 and $616.0 thousand at December 31, 2025) and Carolina Stone reporting unit ($758.0 thousand at both dates) was recognized at acquisition-date fair value in the respective 2025 business combinations (see Note 4); no impairment indicators were identified for these reporting units, and no remeasurement was required, through March 31, 2026. Total goodwill of $18,461.0 thousand at March 31, 2026 and $18,460.0 thousand at December 31, 2025 agrees to the consolidated balance sheets and to the goodwill roll-forward in Note 7. The February 2026 warrants issued to 3i, LP — a non-recurring Level 3 fair value measurement during the period — are described in Note 14.

Significant unobservable inputs used in the Level 3 measurement of the derivative liabilities (Black-Scholes option-pricing model) are summarized below:

	SSN #1 at			SSN #2 at
	Issuance			Issuance			March 31,			December 31,
	(7/29/2025)			(10/22/2025)			2026			2025
Expected term (years)		0.51			0.5			0.06–0.33			0.08–0.31
Risk-free rate		4.28	%		3.78	%		3.70%–3.74	%		3.67%–3.74	%
Annualized volatility		129.3			144.80	%		119.40	%		137.40	%

In addition to the embedded derivative liabilities described above, the Company's Level 3 recurring fair value measurements include contingent earn-out consideration of $352 at both March 31, 2026 and December 31, 2025, comprising $250 from the Carolina Stone acquisition and $102 from the Fraser Canyon acquisition at each date. The fair value of each earn-out was determined at the respective acquisition date using an option pricing model implemented through a Monte Carlo simulation of the underlying EBITDA of each acquired business. As there were no material changes in management's underlying EBITDA forecasts or other significant unobservable inputs from the respective acquisition dates through March 31, 2026, the contingent earn-out consideration continues to be carried at its acquisition-date fair value, and no remeasurement was required during the three months ended March 31, 2026.

The significant unobservable inputs used in the Carolina Stone earn-out valuation included EBITDA volatility of 35.0%, a risk-adjusted discount rate of 15.00% to 15.50%, and risk-free rates of 3.75% to 4.37% across the three annual measurement periods through 2027, with forecasted annual EBITDA ranging from $285 to $1,021. The Carolina Stone earn-out is capped at $825 per annual measurement period subject to EBITDA floors and targets of $800 to $1,000. For the Fraser Canyon earn-out, the significant unobservable inputs included EBITDA volatility of 40.0%, a risk-adjusted discount rate of 11.50%, and risk-free rates of 3.55% to 3.63% across the three annual measurement periods through 2028, with forecasted annual EBITDA ranging from CAD $776 to CAD $1,065.

The fair value of the contingent earn-out consideration is most sensitive to changes in projected EBITDA, EBITDA volatility, and the risk-adjusted discount rate. Significant increases (decreases) in expected EBITDA would result in a higher (lower) fair value measurement. Significant increases (decreases) in EBITDA volatility generally result in a higher (lower) fair value given the option-like payoff structure. Increases (decreases) in the risk-adjusted discount rate would result in a lower (higher) fair value. Changes in the fair value of the earn-out liabilities are recognized within operating expenses in the consolidated statements of operations.

The fair value of the embedded derivative liabilities is highly sensitive to changes in the expected volatility input. Significant increases (decreases) in the expected annualized volatility would result in a significantly higher (lower) fair value measurement of the derivative liabilities, which would be recognized as a non-operating loss (gain) in the consolidated statements of operations.

Note 9 Investment in Non-Marketable Securities

On January 15, 2021, Capstone acquired a minority interest in a consumer products company, Diamond Products Holdings, LLC (“Diamond”), a sexual wellness holding company. The structure of the transaction was as follows: i) Brookstone Acquisition Partners XXI Corporation (“Brookstone XXI”) contributed its approximately 95% equity interest in Diamond, which represented approximately 62% equity ownership on a fully-diluted basis, to Diamond Products Holdings, LLC (“DPH”); ii) The Company formed Capstone Beta LLC (“Beta”) as a wholly-owned subsidiary, and Beta purchased a portion of Brookstone XXI’s interest in DPH; iii) Beta issued a promissory note to Brookstone XXI in the original principal amount of $8.0 million, bearing interest at 1% per annum over a 36 month term, and secured its obligations thereunder by pledging Beta’s interests in DPH; and iv) As additional credit support, Capstone issued a limited payment guaranty to Brookstone XXI in the amount of 10% of the principal amount of Beta’s promissory note. The terms of the promissory note issued by Beta to Brookstone XXI include provisions whereby in the event that the membership interests in Diamond are sold or otherwise disposed of, any proceeds received by Beta are to be utilized to prepay the promissory note to Brookstone XXI and Brookstone XXI’s remaining recourse for the remaining note balance, if any, is limited to the pledged collateral (Beta’s membership interest in DPH) and the $800.0 thousand limited payment guarantee provide by Capstone. DPH was structured to hold one asset, the membership interest in Diamond, and accordingly upon the sale or other disposition of the membership interests in Diamond, the sole recourse of payment by Brookstone XXI is the $800.0 thousand limited payment guarantee. In summary, the intent of Brookstone XXI and the special committee of Capstone’s independent directors entering this arrangement was to limit Capstone’s downside risk to $800.0 thousand.

Diamond was previously sold to its lender in satisfaction of outstanding secured indebtedness, and the Company recognized an impairment charge equal to its full basis in the investment. As of March 31, 2026, and December 31, 2025, the carrying value of the Company's investment in DPH was $0, and no amount is presented in the accompanying consolidated balance sheets.

Note 10 Line of Credit

On December 20, 2017, TotalStone executed a Revolving Credit, Term Loan and Security Agreement with Berkshire Bank (the “Revolving Credit Agreement”). The Revolving Credit Agreement has been amended fifteen times through the fiscal year ended December 31, 2025. In connection with the Carolina Stone acquisition, CS Purchase Holdings LLC, Carolina Stone Holdings, LLC, and Carolina Stone Distributors, LLC were added as co-borrowers under the Fourteenth Amendment, dated August 22, 2025.

The Borrower is required to maintain minimum undrawn availability of $317,000 at all times. The balance outstanding on the line of credit was $ 9.6 and $7.9 million as of March 31, 2026 and December 31, 2025 respectively. Financial covenants include a minimum Cash Flow Coverage Ratio of 1.15x and a minimum Tangible Net Worth of $1,250,000. As of March 31, 2026, the borrowers were not in compliance with the minimum Cash Flow Coverage Ratio under the Revolving Credit Agreement. The Company received a written waiver of the covenant noncompliance from Beacon Bank & Trust dated May 18, 2026. The lender has not declared an Event of Default or accelerated the obligations under the Revolving Credit Agreement.

In connection with the Fraser Canyon acquisition, on November 7, 2025, Canadian Stone Industries and Klad Envelope Solutions Inc. entered into a Letter of Agreement with The Toronto-Dominion Bank ("TD Bank") providing Canadian Stone Industries with a revolving operating loan with a credit limit of CAD $5,000,000 for working capital purposes. Advances are available as Prime Rate Based Loans at Prime Rate + 0.50% per annum or United States Base Rate Loans at USBR + 0.50% per annum. The facility is uncommitted and repayable on demand. Advances are limited to a formula-based amount equal to the lesser of (i) CAD $5,000,000 and (ii) the sum of 80% of eligible Canadian and U.S. accounts receivable plus 50% of inventory held in Canada net of 30-day accounts payable. The balance outstanding on the TD Bank operating loan was approximately $3.1 million and $2.4 million as of March 31, 2026 and December 31, 2025 respectively. The TD Bank credit facility is secured by first-priority General Security Agreements from Canadian Stone Industries, Fraser Canyon Holdings Inc., Canadian Stone Industries (2022) Inc., Klad Envelope Solutions Inc., and Instone Canada Corp., covering all present and after-acquired personal property. Instone Canada Corp. has provided an unlimited guarantee. Financial covenants include a minimum trailing twelve-month Debt Service Coverage Ratio of 1.25x. As of March 31, 2026, the Borrowers were in compliance with the financial covenants under the TD Bank Letter of Agreement.

Liquidity and Nasdaq Listing Compliance

In January 2026, the Company received a notification from the Nasdaq Stock Market indicating that the closing bid price of its Common Stock had been below $1.00 per share for 30 consecutive business days and that the Company was therefore not in compliance with Nasdaq Listing Rule 5550(a)(2). The Company has until July 6, 2026 to regain compliance, and the Board of Directors intends to seek shareholder authorization at the 2026 Annual Meeting to effect a reverse stock split, if needed, to satisfy the minimum bid price requirement. Continued listing on Nasdaq is an important component of the Company's access to capital markets, including its ability to issue shares under the ELOC and to raise additional equity capital on favorable terms. A delisting or prolonged non-compliance could adversely impact the Company's liquidity position. In addition, the Company has generated recurring net losses, including a net loss of $1,915 thousand for the three months ended March 31, 2026, and has had negative cash flow from operations in each of the past two fiscal years.

The Company’s recurring net losses, accumulated deficit, and upcoming debt maturities represent conditions that, in the aggregate, could raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date these consolidated financial statements are issued. Management has evaluated these conditions together with the Company's liquidity resources and operational plans. In April 2025, the Company entered into a $20.0 million Equity Line of Credit agreement with the Equity Line Investor (the "ELOC"), under which the Company has the right, but not the obligation, to require the Equity Line Investor to purchase shares of Common Stock from time to time, subject to certain conditions, including a per-notice "VWAP Purchase Maximum Amount", under which the Company may sell shares of its Common Stock from time to time to the Equity Line Investor at pricing determined under the ELOC agreement, subject to certain conditions, including the Company's continued Nasdaq listing. As of December 31, 2025, approximately $19.5 million remained undrawn under the ELOC, and as of May 19, 2026, approximately $19.2 million remained undrawn. The Company's ability to access the ELOC is subject to certain conditions, including the maintenance of the Company's Nasdaq listing (with respect to which the Company is currently not in compliance with the $1.00 per share minimum bid price requirement, as described above), the per-notice VWAP Purchase Maximum Amount, and other limitations under the ELOC. The Company intends to continue using the ELOC as a component of its liquidity strategy alongside its Revolving Credit Agreement. The Company is also actively integrating the businesses acquired in 2025 and implementing plans to realize operating synergies and cost reductions across the combined platform. On the revenue side, management is expanding the Company's product offering — including new stone veneer lines, complementary hardscape and masonry categories, and broader distribution into the Carolinas and Canadian markets — to drive organic growth and improve operating leverage in 2026. Based on this evaluation, management believes these plans alleviate the substantial doubt. Accordingly, the Company’s cash and available liquidity are expected to be sufficient to fund operations and meet obligations for at least one year from the issuance date of these consolidated financial statements.

Representative's Warrant. In connection with the March 7, 2025, Public Offering, the Company issued warrants to the underwriters to purchase 62,500 shares of Common Stock at an exercise price of $4.00 per share. The Representative's Warrant became exercisable on September 5, 2025, and expires on September 7, 2026. As of March 31, 2026, no portion had been exercised.

February 2026 Warrant (3i, LP). On February 12, 2026, in connection with the Letter Agreement deferring the $606,054 installment payment originally due January 22, 2026 under SSN #2 (see Note 11), the Company issued to 3i, LP a five-year warrant to purchase 405,000 shares of Common Stock at an exercise price of $0.01 per share, expiring February 12, 2031. The Company evaluated the modification under ASC 470-50, concluded the 10% test was not met, and accounted for it as a modification. The warrant was classified as equity under ASC 815-40 and is not subject to recurring remeasurement. The fair value of $203 thousands was estimated using the Black-Scholes option-pricing model with the following inputs: stock price $0.5077 (CAPS closing on 2/12/2026), exercise price $0.01, expected term 5.0 years, risk-free rate 3.67%, dividend yield 0%, and annualized volatility 100.5%. The fair value was recorded as an increase to additional paid-in capital with a corresponding discount on SSN #2, which is being amortized to interest expense over the remaining term to maturity. As of March 31, 2026, no portion of the warrant had been exercised.

As of March 31, 2026, the Company had 11,423,707 shares of Common Stock issued and 9,428,707 outstanding, the difference representing 1,995,000 unvested restricted stock awards granted on March 30, 2026 that have voting rights but are excluded from basic earnings per share until vesting and 25,000,000 shares of preferred stock authorized, of which 2,000,000 are designated as Series B Preferred Stock (985,063 shares issued and outstanding) and 3,500,000 are designated as Series Z 8% Non-Convertible Preferred Stock (1,467,532 shares issued and outstanding, classified as a liability pursuant to ASC 480).

In June 2015, our stockholders approved the 2015 Equity Incentive Plan (the “2015 Plan”) and reserved 1,000,000 shares of our common stock for issuance. At March 31, 2026 and December 31, 2025, no shares remained available to grant under the Plan and all granted shares are fully vested.

Stock-based compensation expense reflects the fair value of stock-based awards measured at the grant date and recognized over the relevant vesting period. The Company generally estimates the fair value of each stock-based award on the measurement date using the Black-Scholes option valuation model which incorporates assumptions as to stock price volatility, the expected life of the options, risk-free interest rate and dividend yield. No options were granted in 2026 or 2025.

Stock Compensation

On March 30, 2026, the Board of Directors approved the Capstone Holding Corp. 2025 Stock Incentive Plan (the “2025 Plan”), reserving up to 5,000,000 shares of common stock for issuance in the form of stock options, restricted stock awards, and other equity-based awards. On the same date, the Board approved an initial grant of 1,995,000 restricted stock awards (“RSAs”) under the 2025 Plan, at a grant-date fair value of $0.6490 per share (the closing price of the Common Stock on the Nasdaq Capital Market on March 30, 2026), resulting in aggregate grant-date fair value of approximately $1,295,000. The grants are bifurcated into two cohorts: (i) 1,116,250 shares that vest in full on the third anniversary of the grant date ( March 30, 2029) subject to continued service, recognized straight-line over the 36-month service period; and (ii) 878,750 shares that vest in full upon the recipient’s separation from the Board of Directors, with the requisite service period inferred from the recipient’s remaining director term. Because the grants were made on the last day of the quarter, stock-based compensation expense recognized for the three months ended March 31, 2026 was de minimis. Total unrecognized compensation cost related to these grants was approximately $1,295,000 as of March 31, 2026, expected to be recognized over a period of 36 months for cohort (i) and through the separation date from the Board of Directors, a weighted-average period of approximately 10 months, for cohort (ii).

As of March 31, 2026 and December 31, 2025, there were 0 and 50 stock options exercisable and vested at a weighted-average exercise price of $163.00, respectively. During 2026 and 2025, 50 and 450 options expired unexercised. No options were granted or exercised in 2026 or 2025.

The Brookstone Partners warrant expired unexercised on April 1, 2024.

Preferred Stock

On February 20, 2025, following the Company’s controlling shareholder’s approval, the Company filed an amendment to its Restated Certificate of Incorporation to increase the authorized shares of preferred stock to 25,000,000 shares. As of March 31, 2026, the Company had 985,063 shares of Series B Preferred Stock outstanding. Additionally, 1,467,532 shares of Series Z 8% Non-Convertible Preferred Stock were issued and outstanding; however, the Series Z Preferred Stock is classified as a liability on the consolidated balance sheet pursuant to ASC 480, Distinguishing Liabilities from Equity (see Series Z disclosure below).

The Tax Benefit Preservation Plan adopted by the Board on April 18, 2017 between the Company and Computershare, which had been extended in May 2024 through December 31, 2027, was cancelled on March 3, 2025 pursuant to the Master Exchange and Other Transaction Agreement.

Series B Preferred Stock: In February 2025, the Company filed the Certificate of Designation of Preferences, Rights and Limitations of Series B Preferred Stock with the Delaware Secretary of State, designating 2,000,000 shares as Series B Preferred Stock, no par value. Nectarine Management, LLC, an entity controlled by Michael Toporek, the chairman of the board of directors, purchased 985,063 shares of Series B Preferred Stock for a purchase price of $30,000. The holders of Series B Preferred Stock have the right to vote together with common stockholders, casting one vote per share. Series B Preferred Stock is convertible into Common Stock at the holder’s option after the two-year anniversary of the Company’s February 2025 initial public offering, provided the Common Stock’s closing price meets or exceeds $40 per share. Until less than 50% of the originally issued Series B Preferred Stock remains outstanding, holders of at least 50% of such shares may appoint two directors to the Board and the Company cannot take certain corporate actions without the approval of at least 50% of the outstanding Series B Preferred Stock.

Series Z 8% Non-Convertible Preferred Stock (Classified as Liability): On September 30, 2025, the Company filed the Certificate of Designation of Preferences, Rights and Limitations of Series Z 8% Non-Convertible Preferred Stock with the Secretary of State of the State of Delaware, designating 3,500,000 shares as Series Z Preferred Stock, no par value. A total of 1,467,532 shares were issued to BP Peptides, LLC (642,364 shares) and Brookstone Partners Acquisition XXI Corporation (825,168 shares), both affiliates of Brookstone Partners, the Company’s majority shareholder, in exchange for the extinguishment of outstanding related party promissory notes with a combined principal and accrued interest balance of approximately $1.94 million. The shares were issued pursuant to the exemption from registration under Section 4(a)(2) of the Securities Act of 1933, as amended. The Series Z Preferred Stock is non-convertible and carries a cumulative dividend at the rate of 8% per annum, accruing daily on the $1.32 per share stated value based on a 360-day year of twelve 30-day months. Accrued but unpaid dividends compound quarterly. The Series Z Preferred Stock is mandatorily redeemable at the earlier of (a) the seventh anniversary of the original issue date ( September 30, 2032) or (b) the occurrence of a Fundamental Transaction, at a redemption price equal to the stated value plus all accrued and unpaid dividends. Because the Series Z Preferred Stock embodies an unconditional obligation requiring the Company to transfer assets to redeem the instrument at a specified date, and the instrument is non-convertible, the Company has classified the Series Z Preferred Stock as a liability in accordance with ASC 480-10-25-4, Distinguishing Liabilities from Equity. The Series Z liability was initially measured at fair value, which approximated the aggregate stated value of $1,936,893, and is subsequently measured using the interest method, with periodic accretion of interest expense at the 8% contractual rate. Interest expense of approximately $39,500 was recognized for the period from December 31, 2025, through March 31, 2026. The carrying value of the Series Z liability, including accrued interest as of March 31, 2026 and December 31, 2025, was approximately $ 2,015 thousands and $1,976 thousands respectively.

In connection with the Public Offering that closed on March 7, 2025, the Company issued to the underwriters warrants to purchase an aggregate of 62,500 shares of Common Stock (the “Representative’s Warrant”), representing 5% of the shares issued in the Public Offering. The Representative’s Warrant is exercisable commencing on September 5, 2025 and expiring on September 7, 2026, at an exercise price of $4.00 per share. As of March 31, 2026, the Representative’s Warrant had not been exercised.

The Company’s Senior Secured Convertible Notes (see Note 11) are convertible into shares of Common Stock at conversion prices ranging from $0.75 to $1.10 per share. During the year ended December 31, 2025, holders converted an aggregate principal amount of $2,897,196 into 3,166,667 shares of Common Stock at conversion prices ranging from $0.75 to $1.00 per share. As of December 31, 2025, the remaining outstanding principal of $3,859,541 would be convertible into approximately 4,393,933 shares of Common Stock at conversion prices ranging from $0.75 to $1.10 per share. As of March 31, 2026, the remaining outstanding principal of $3,625,896 would be convertible into approximately 4,082,407 shares of Common Stock at conversion prices ranging from $0.75 to $1.10 per share. Subsequent to March 31, 2026, the conversion price applicable to $500,000 of principal under the October Note was reduced to $0.57 per share (see Note 19).

On February 12, 2026, the Company and the Buyer entered into a Letter Agreement (the "February 2026 Letter Agreement") deferring the $606,054 installment payment originally due January 22, 2026 under the October Note to the Maturity Date. As consideration for the deferral, the Company issued to the Buyer warrants to purchase 405,000 shares of Common Stock at an exercise price of $0.01 per share, with a five-year term expiring February 12, 2031. The Company evaluated the modification under ASC 470-50 and concluded that the change in the present value of cash flows under the modified terms did not exceed 10% of the present value of cash flows under the original terms, and accordingly accounted for the transaction as a modification rather than an extinguishment. The Company estimated the fair value of the warrants at $202,734 using the Black-Scholes option pricing model with the following inputs: stock price of $0.5077 (the closing price of the Common Stock on the issuance date), exercise price of $0.01, expected term of 5.0 years, risk-free rate of 3.67%, dividend yield of 0%, and annualized volatility of 100.5%. The warrants were classified as equity in accordance with ASC 815-40, and the fair value was recorded as an increase to additional paid-in capital with a corresponding discount on the October Note, which is being amortized to interest expense over the remaining term to maturity. During the three months ended March 31, 2026, $37,812 of the discount was amortized to interest expense.

Note 16 TotalStone 401(K) Retirement Savings Plan

TotalStone maintains a defined contribution pension plan, which covers all employees electing to participate after completing certain service requirements. Employer contributions are made at the Company’s discretion. Generally, the Company makes safe harbor matching contributions equal to 100% of employee contributions up to 4% of the employee’s Plan Compensation, as defined. Each participant is 100% vested in their salary deferral and the safe harbor matching contributions. Other employer discretionary contributions are subject to a graded vesting schedule. Company matching contribution expense was approximately $32.6 thousand for the three months ended March 31, 2026.

Carolina Stone Distributors, LLC maintained a SIMPLE IRA plan covering eligible employees after 90 days of service. Under the plan, Carolina Stone matched employee contributions up to 3% of eligible compensation. Employer matching contributions for the period from the acquisition date of August 22, 2025 through December 31, 2025 totaled $10.0 thousand. The SIMPLE IRA was terminated effective December 31, 2025, and Carolina Stone employees became eligible to participate in TotalStone's 401(k) Plan effective January 1, 2026; contributions on their behalf during the three months ended March 31, 2026 are included within the TotalStone matching contribution expense disclosed above.

Canadian Stone Industries Inc. sponsors a Group Registered Savings Plan ("Group RSP") through RBC covering all employees after three months of continuous service. Under the plan, CSI matches employee contributions at 2% of eligible compensation with immediate vesting. Employer matching contributions for the three months ended March 31, 2026 totaled approximately $4.9 thousand.

Note 17 Income Taxes

The Company's effective tax rate for the three months ended March 31, 2026 and 2025 was 0.0%. In both periods, the Company maintained a full valuation allowance against its U.S. net deferred tax assets and accordingly recognized no income tax benefit on its U.S. pretax losses. The three months ended March 31, 2026 income tax provision of approximately $2.0 thousand represents Canadian income taxes on the operations of Canadian Stone Industries Inc. The three months ended March 31, 2025 effective tax rate of 0.0% represents U.S. state and local income tax expense for which no tax benefit was recognized.

Overview

Capstone Holding Corp., ~~formerly known as Capstone Therapeutics Corp. and OrthoLogic Corp.,~~ incorporated in Delaware in 1987 as a domestic corporation, is ~~the~~a ~~parent~~national, ~~entity~~technology-enabled ofbuilding products distribution and installation platform. Through our three operating subsidiaries — Instone (TotalStone, LLC), ~~(dba~~Canadian ~~Instone).~~Stone ~~Instone~~Industries ~~has~~(Fraser aCanyon ~~building~~Holdings ~~products~~Inc. ~~distribution~~and ~~network~~its ~~that~~subsidiaries, ~~services~~“CSI”), 31and USCarolina ~~states~~Stone (~~with~~Carolina ~~such~~Stone ~~states~~Distributors, ~~having~~LLC) ~~over 60%~~— ofwe ~~American~~distribute ~~households).~~and ~~Our~~install ~~over~~thin ~~400~~veneer ~~active~~stone, ~~customers~~natural ~~are~~stone, ~~primarily~~manufactured ~~masonry~~stone, ~~building~~and ~~materials~~related masonry and ~~landscape~~hardscape ~~dealers~~products for residential and commercial construction markets across 38 U.S. states and two Canadian provinces.

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.

Sales were $34.4 million for the nine months ended September 30, 2025 compared to $34.6 million for the nine months ended September 30, 2024. Revenue decreased between the nine months ended September 30, 2025 and 2024 by $158.0 thousand.

Cost of goods sold

Cost of goods sold decreased by $366.0 thousand, or 1%, for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024.

Selling general and administrative expenses

Selling general and administrative expenses increased by $1.7 million, or 22.0%, for the nine months ended September 30, 2025 compared to the nine months ended September 30, 2024. The increase results primarily from an increase in investor relations of $1.0 million and the acquisition of Carolina Stone Holdings.

Transaction expenses

Transaction expenses increased by $652.0 thousand or 100% for the nine months ended September 30, 2025. The increase is related to transaction expenses for the Company’s acquisition expenses.

Loss on extinguishment of debt

Loss on extinguishment of debt increased by $652.0 thousand for the nine months ended September 30, 2025. The increase relates to a substantial change to the conversion feature of the Company’s Convertible Notes in accordance with ASC 470-50 (see Note 10).

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.

Income Tax Expense

Income tax expense decreased by $22.0 thousand or 100% for the nine months ended September 30, 2025, compared to the nine months ended September 30, 2024.

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 the Company. The 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 $2.89 million and $23.18 million as of March ~~September 30~~31, ~~2025~~2026 and December 31, ~~2024~~2025, respectively. The $~~700.~~0.9 ~~thousand~~ million decrease was primarily driven by a $2.4 million increase in ~~working~~borrowings ~~capital~~under isour ~~primarily~~revolving ~~attributable~~line toof ancredit and a $2.0 million increase in accounts ~~receivable~~payable, ~~inventory~~partially ~~and cash;~~ offset by ~~accounts~~a ~~payable and~~$2.0 anmillion increase in ~~our~~accounts ~~revolving~~receivable ~~line~~and ofa ~~credit~~$1.0 million increase in inventory.

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~~ Table of ~~the~~Contents ~~Revolver’s financial covenants which have been waived by our lender. As of September 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.

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 March 31, 2026 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.

The Company’s ability to continue as a going concern depends on its ability to generate sufficient cash flows from operations, access additional capital, and manage its debt maturities. The Senior Secured Convertible Notes mature in July and October 2026. The Company’s U.S. revolving credit facility with Beacon Bank & Trust (successor by merger to Berkshire Bank) matures in June 2026, and Canadian Stone Industries’ operating loan with TD Bank is subject to annual renewal. The mezzanine term loan with Stream Finance, LLC matures in September 2027. Management is evaluating alternatives to refinance or extend these obligations and believes that the Company’s existing cash, availability under its revolving credit facilities, and expected operating cash flows will be sufficient to fund operations for at least the next twelve months from the date of this filing.

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.

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 ~~September~~March 3031, ~~2025~~2026, our disclosure controls and procedures were not effective. The ineffectiveness of our 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~~which inhas ahistorically ~~situation~~resulted ~~where~~in limitations on segregation of duties ~~exist~~. ~~All~~To ~~responsibility~~address ~~for~~this ~~accounting~~matter ~~entries~~ and the ~~creation~~ ofrelated ~~financial~~material ~~statements has historically been held primarily by a single person~~weakness, ~~though~~ the Company ~~engages~~has ~~multiple~~undertaken ~~accounting consultants for accounting, tax~~ and ~~audit~~continues ~~support.~~to Inimplement ~~April 2025,~~ the ~~Company~~following ~~hired~~remediation ~~a controller.~~steps:

Process and review enhancements. The Company has implemented additional review procedures over journal entries, account reconciliations, and the consolidation process. Management is documenting key accounting policies, formalizing close calendars and review checklists, and engaging multiple external accounting, tax, and audit consultants to supplement internal staffing during the remediation period.

Post-acquisition disclosure controls. Following the acquisitions of Carolina Stone Holdings on August 22, 2025 and Fraser Canyon Holdings on December 1, 2025, the Company has integrated each acquired business into its quarterly disclosure controls and procedures, including expanding the close calendar to incorporate the acquired entities, aligning the chart of accounts and reporting packages, and extending review and certification responsibilities to the acquired-entity finance leads.

Expected timing. The Company expects the remediation steps described above, taken together with the completion of the additional staff accountant hire for TotalStone and the continuing engagement of external accounting consultants, to substantially remediate the identified material weaknesses by the end of fiscal year 2026, subject to the operating effectiveness of the new controls being demonstrated for a sufficient period of time.

The Company will continue to evaluate the design and operating effectiveness of its internal control over financial reporting, and management will reassess the remediation status quarterly. Until the remediation is complete and the relevant controls have operated effectively for a sufficient period, the material weaknesses described above will continue to exist.

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 ~~September~~March 3031, ~~2025~~2026 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~~This ~~information~~Quarterly ~~regarding~~Report ~~the~~contains ~~risk~~forward-looking ~~factors~~statements that ~~could~~ ~~affect~~involve ~~the~~risks ~~Company’s~~and ~~business,~~uncertainties. ~~results~~Our ofactual ~~operations,~~results ~~financial~~could ~~condition~~differ ~~and~~materially ~~liquidity,~~from ~~see~~those ~~the~~discussed ~~information~~in ~~under~~this ~~Part~~Quarterly ~~I, Item 1A~~Report. ~~“Risk~~ Factors” inthat ~~the~~could ~~Form~~cause ~~10-K,~~or ~~which~~contribute isto ~~accessible~~these ondifferences ~~the~~include, ~~SEC’s~~but ~~website~~are atnot ~~www.sec.gov.~~limited ~~There have been no material changes~~ to, ~~the~~those ~~risk~~discussed ~~factors~~below ~~previously~~and ~~disclosed~~elsewhere in ~~the~~this ~~Form~~Quarterly ~~10-K~~Report.

You should carefully consider the risk factors disclosed in Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (the "2025 Form 10-K"), together with all other information in this Quarterly Report, including our unaudited condensed financial statements and notes thereto, and in our other filings with the Securities and Exchange Commission. If any such risks, including the risk set out below, or other risks not presently known to us or that we currently believe to not be significant, develop into actual events, then our business, financial condition, results of operations or prospects could be materially adversely affected. If that happens, the market price of our common stock could decline, and stockholders may lose all or part of their investment.

In addition to the risk factors set forth in the 2025 Form 10-K, the following risk factors represent material updates to our risk factor disclosures. The risk factors set forth in the 2025 Form 10-K, as updated by the foregoing, should be read in conjunction with the other information set forth in this Quarterly Report.

We were not in compliance with the minimum Cash Flow Coverage Ratio under our Revolving Credit Agreement as of March 31, 2026, and although we have received a written waiver from our lender, there can be no assurance that we will maintain compliance in future periods or that our lender will grant additional waivers, which could result in acceleration of our outstanding indebtedness and materially impair our liquidity.

As of March 31, 2026, we were not in compliance with the minimum Cash Flow Coverage Ratio covenant under our Revolving Credit Agreement with Beacon Bank & Trust. On May 18, 2026, we received a written waiver limited to this specific violation; the waiver does not extend to any future defaults or events of default.

There can be no assurance that we will maintain compliance in future periods or that our lender will grant additional waivers if we do not. Any future waiver, if obtained, may be conditioned upon terms less favorable to the Company, including increased interest rates, additional collateral requirements, or other operational restrictions. If we fail to obtain a necessary waiver, our lender could declare an event of default, accelerate all outstanding amounts under the Revolving Credit Agreement, and exercise its remedies against pledged collateral. Acceleration could also trigger cross-default provisions in our other debt agreements, including the October Note, and could materially impair our financial condition and our ability to continue as a going concern. Recurring covenant non-compliance may also impair our ability to access additional financing and may be viewed unfavorably by investors and counterparties.

The reduction of the conversion price under the October Note and the resulting conversion of a substantial portion of the principal and accrued interest into shares of common stock resulted in significant dilution to our existing stockholders, and future conversions at the reduced conversion price or further reductions in the conversion price could result in additional substantial dilution.

On April 16, 2026, we reduced the conversion price applicable to $500,000 of the principal amount outstanding under the October Note to $0.57 per share. On the same date, the buyer converted an aggregate of $1,725,136 of principal and $120,762 of accrued interest into 2,557,198 shares of common stock, increasing our outstanding share count by approximately 22% in a single day.

This conversion has resulted in significant dilution to existing stockholders with respect to earnings, book value, and voting power per share, and may depress the market price of our Common Stock. If additional principal or interest is converted at the reduced price, or if we further reduce the conversion price, stockholders will experience additional material dilution. The shares of common stock issuable upon conversion of remaining unconverted principal may exert continued downward pressure on our stock price, which could impair our ability to raise capital through equity offerings or our Equity Line of Credit and could make any future conversions even more dilutive.

Table of Contents

We have received a notification from Nasdaq regarding non-compliance with the minimum bid price requirement, and failure to regain compliance could result in delisting of our Common Stock.

In January 2026, the Company received a notification from the Nasdaq Stock Market indicating that the closing bid price of its Common Stock had been below $1.00 per share for 30 consecutive business days, and that the Company was therefore not in compliance with Nasdaq Listing Rule 5550(a)(2). The Company has until July 6, 2026, to regain compliance, which requires the closing bid price of its Common Stock to be at least $1.00 per share for a minimum of 10 consecutive business days. If the Company does not regain compliance within the initial compliance period, it may be eligible for an additional 180-day compliance period, subject to meeting certain requirements. There can be no assurance that the Company will be able to regain compliance. If the Company fails to regain compliance, its Common Stock may be subject to delisting from Nasdaq, which could materially adversely affect the liquidity and trading price of its Common Stock and its ability to raise capital. In January 2025, the SEC approved amendments to Nasdaq Listing Rule 5810(c)(3)(A) that restrict the ability of listed companies to use reverse stock splits as a compliance tool. Under the amended rules, if a company effects a reverse stock split and subsequently fails to maintain the minimum bid price requirement within one year, the company will not be eligible for any compliance period and Nasdaq will issue a delisting determination. In addition, companies that effect reverse stock splits with a cumulative ratio of 250-to-1 or greater over any two-year period are subject to immediate delisting without a compliance period. The Company’s Board of Directors is seeking shareholder authorization at the 2026 Annual Meeting to effect a reverse stock split as a potential backstop measure to regain compliance if necessary. However, even if authorized and effected, a reverse stock split may not result in sustained compliance with the minimum bid price requirement, and the amended Nasdaq rules would preclude the Company from relying on an additional compliance period if the stock price subsequently falls below $1.00 within one year of such reverse split.

Changes in foreign currency translation and transaction risks that could adversely affect our reported financial results and the cost of servicing our Canadian dollar-denominated obligations.

Our Canadian operating subsidiary, Canadian Stone Industries Inc., generates revenues and incurs expenses in Canadian dollars, and we have outstanding debt and seller notes denominated in Canadian dollars. These exposures subject us to foreign currency translation risk when consolidating the subsidiary's results into U.S. dollars, and to transaction risk affecting the U.S. dollar cost of servicing our Canadian dollar-denominated obligations.

Fluctuations in the CAD/USD exchange rate may cause variability in our reported financial results independent of underlying operating performance. While this risk was not material in prior periods, it could become increasingly material if our Canadian operations or Canadian dollar-denominated indebtedness grow or as exchange rate volatility increases.
