Summary of Significant Accounting Policies

Note 3: Summary of Significant Accounting Policies

Basis of Presentation – The consolidated financial statements are prepared in conformity with accounting principles accepted in the United States of America (“GAAP”).

The consolidated financial statements and related disclosures as of March 31, 2026, are unaudited, pursuant to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with US GAAP have been condensed or omitted pursuant to such rules and regulations. In our opinion, these unaudited financial statements include all adjustments (consisting only of normal recurring adjustments) necessary for the fair statement of the results for the interim periods. These unaudited financial statements should be read in conjunction with the audited financial statements of the Company for the years ended December 31, 2025, and 2024 included in our Annual Report on Form 10-K for the year ended December 31, 2025, filed with the SEC on April 15, 2026. The results of operations for the three months ended March 31, 2026, are not necessarily indicative of the results to be expected for the full year ended December 31, 2026.

Principles of Consolidation – The accompanying consolidated financial statements include the accounts of Mitesco, Inc., and its wholly owned subsidiaries Mitesco NA, LLC, The Good Clinic, LLC, Vero Technology Ventures, LLC, and Centcore, LLC. In addition, we relied on the operating activities of certain legal entities in which we did not maintain a controlling ownership interest, but over which we had indirect influence and of which we were considered the primary beneficiary. These entities are typically subject to nominee ownership and transfer restriction agreements that effectively transfer the majority of the economic risks and rewards of their ownership to the Company. The Company’s management, restrictions and other agreements concerning such nominee-owned entities typically includes both financial terms and protective and participating rights to the entities’ operating, strategic and non-clinical governance decisions which transfer substantial powers over and economic responsibility for these entities to the Company. As such, the Company applies the guidance of the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 810 – Consolidation (“ASC 810”), to determine when an entity that is insufficiently capitalized or not controlled through its voting interests, referred to as a variable interest entity should be consolidated. All intercompany balances and transactions have been eliminated.

Use of Estimates - The preparation of these financial statements requires our management to make estimates and assumptions about future events that affect the amounts reported in the financial statements and related notes. Future events and their effects cannot be determined with absolute certainty. Therefore, the determination of estimates requires the exercise of judgment.

Revenue Recognition – The Company recognizes revenue in accordance with ASC 606 when it has satisfied the performance obligations under an arrangement with the customer reflecting the terms and conditions under which products or services will be provided, the fee is fixed or determinable, and collection of any related receivable is probable. ASC Topic 606, “Revenue from Contracts with Customers” establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the entity’s contracts to provide goods or services to customers. Revenues are recognized when control of the promised goods or services are transferred to a customer, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. The Company applies the following five steps in order to determine the appropriate amount of revenue to be recognized as it fulfills its obligations under each of its agreements: 1) identify the contract with a customer; 2) identify the performance obligations in the contract; 3) determine the transaction price; 4) allocate the transaction price to performance obligations in the contract; and 5) recognize revenue as the performance obligation is satisfied.

Our revenues generally relate to data center services. Revenues are recorded during the period our obligations to provide services are satisfied. The Company’s performance obligation for its revenue stream is to provide the access to its data centers to the customer, and revenues associated with completed sales are recognized rateably over the contractual term as services are provided to the customer. There is no significant financing component to the Company’s sales.

In September 2025 we received a contract for development of a new application intended to effect the listing and sale of properties and products specifically related to sports. We expect this project to be executed using both internal and external resources and to be completed in late FY2026. As of March 31, 2026, we have received an upfront fee of $10,000, which is reflected as deferred revenue as no performance obligations under the contract have been satisfied. 

Capitalized Software Development Costs - Software development costs primarily consist of personnel costs. We capitalize software development costs upon the establishment of technological feasibility and prior to the availability of the product for general release to clients for software sold to third parties. During the three months ended March 31, 2026 and during the year ended December 31, 2025, no costs have been capitalized as we have not yet reached technological feasibility. We begin to amortize capitalized costs when a product is available for general release to clients. Amortization expense is determined on a product-by-product basis at a rate not less than straight-line basis over the software’s remaining estimated economic life.

Software Research and Development Costs - Research and development costs are expensed as incurred and include compensation costs for engineering and product management personnel, third-party contractor expenses, software development tools and other expenses related to researching and developing new solutions or upgrading and enhancing existing solutions that do not qualify for capitalization. We expensed research and development costs of $103,533 during three months ended March, 2026 and $0 in 2025.

Segments - The Company manages its operations as a single segment for the purposes of assessing performance and making operating decisions. The Company’s Chief Operating Decision Maker (“CODM”) is its Chief Executive Officer. The CODM allocates resources and evaluates the performance of the Company at the consolidated level using information about its revenues, gross profit, and income from operations. All significant operating decisions are based upon an analysis of the Company as one operating segment, which is the same as its reporting segment.

Per Share Data - Basic income (loss) per share is computed by dividing net loss by the weighted average number of common shares outstanding for the year. Diluted loss per share is computed by dividing net loss by the weighted average number of common shares outstanding plus common stock equivalents (if dilutive) related to warrants, options, and convertible instruments.

The following table presents the effect of potential dilutive issuances for the three months ended March 31, 2026 and 2025:

	Three Months Ended
	March 31, 2026			March 31, 2025
Net income (loss) attributable to common stockholders	$	803,603		$	3,437,634
Preferred stock dividends		-			1,580
Derivative gain		-			(4,362,645	)
Interest expense associated with convertible debt		-			19,159
Net loss for dilutive calculation		(803,603	)		(904,272	)
Weighted average shares outstanding		17,225,015			9,772,319
Dilutive effect of preferred stock		-			126,748
Dilutive effect of convertible debt		-			2,045,192
Dilutive effect of common stock warrants		-			40,767
Weighted average shares outstanding for diluted net income (loss) per share		17,225,015			11,985,026

During the three months ended March 31, 2026 the effect of 3,286,256 shares issuable upon the conversion of Series A preferred shares, 14,131,738 shares of common stock issuable upon conversion of notes, and 37,556 shares issuable upon exercise of warrants were anti-dilutive and are not included in the computation of dilutive earnings per share. During the three months ended March 31, 2025 the effect of 3,298,159 shares issuable upon the conversion of Series A preferred shares were anti-dilutive and are not included in the computation of dilutive earnings per share.

Financial Instruments and Fair Values - The fair value of a financial instrument represents the amount at which the instrument could be exchanged in a current transaction between willing parties, other than in a forced or liquidation sale. Fair value estimates are made at a specific point in time, based upon relevant market information about the financial instrument. In determining fair value, we use various valuation methodologies and prioritize the use of observable inputs. We assess the inputs used to measure fair value using a three-tier hierarchy based on the extent to which inputs used in measuring fair value are observable in the market:

Level 1 – inputs include exchange quoted prices for identical instruments and are the most observable.

Level 2 – inputs include brokered and/or quoted prices for similar assets and observable inputs such as interest rates.

Level 3 – inputs include data not observable in the market and reflect management judgment about the assumptions market participants would use in pricing the asset or liability.

The use of observable and unobservable inputs and their significance in measuring fair value are reflected in our hierarchy assessment. The carrying amount of cash, prepaid assets, accounts payable and accrued liabilities approximate fair value due to the short-term maturities of these instruments. Because cash and cash equivalents are readily liquidated, management classifies these values as Level 1. The fair value of the derivative liabilities approximates their book value as the instruments are short-term in nature and contain market rates of interest. Because there is no ready market or observable transactions, management classifies the derivative liabilities as Level 3.

Recent Accounting Standards

In November 2024, the FASB issued ASU 2024-03, Disaggregation of Income Statement Expenses, and in January 2025, the FASB issued ASU 2025-01, Clarifying the Effective Date (“ASU 2025-01”). The amendments are intended to enhance disclosures regarding an entity’s costs and expenses by requiring additional disaggregated information disclosures about certain income statement expense line items. The amendments, as clarified by ASU 2025-01, are effective for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the effect of this pronouncement on its disclosures.

In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”). ASU 2025-05 amends ASC, Financial Instruments – Credit Losses (Topic 326) (“ASC Topic 326”) to simplify how entities measure credit losses for current accounts receivable and current contract assets arising from transactions accounted for under ASC, Revenue from Contracts with Customers (Topic 606) (“ASC Topic 606”). This update allows entities to assume that current conditions as of the balance sheet date will remain unchanged for the remaining life of the asset when estimating expected credit losses. ASU 2025-05 is effective for interim and annual periods beginning after December 15, 2025. Early adoption is permitted. The Company adopted this standard effective January 1, 2026, which did not have a material impact on the Company’s consolidated financial statements.

There are various other updates recently issued, most of which represent technical corrections to the accounting literature or application to specific industries and are not expected to have a material impact on the Company’s consolidated financial position, results of operations or cash flows.
