SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NOTE 3 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Principles of Consolidation and Basis of Presentation

The Condensed Consolidated Financial Statements include all of the accounts of the Company and our subsidiaries. We have eliminated all significant intercompany transactions and balances in consolidation. In management’s opinion, all adjustments, consisting only of normal recurring accruals, necessary for a fair statement of our Condensed Consolidated Balance Sheet as of March 31, 2026 and our Condensed Consolidated Statements of Operations for the three months ended March 31, 2026 and 2025 have been made. The results set forth in our Condensed Consolidated Statements of Operations for the three months ended March 31, 2026 and in our Condensed Consolidated Statements of Cash Flows for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the full year. The Condensed Consolidated Balance Sheet as of December 31, 2025 was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States (“GAAP”).

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions about future events that affect the amounts reported in the condensed consolidated financial statements and the accompanying notes. Management bases its estimates on historical experience and other assumptions that it believes to be reasonable at the time. Actual results could differ from those estimates and any such differences may be material to the financial statements. Significant estimates are contained in the accompanying financial statements for the useful lives for depreciation and amortization of long-lived assets, allowance for credit losses, fair value of financial instruments, stock based compensation and the incremental borrowing rate used in determining the right-of-use assets and operating lease liabilities.

Cash and Cash Equivalents

The Company places its cash with high credit quality financial institutions. The Company’s account at these institutions are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. All cash amounts in excess of $250,000 are unsecured. The Company has a deposit placement agreement for Insured Cash Sweep Service (“ICS”). This service is a secure, and convenient way to access FDIC protection on large deposits, earn a return, and enjoy flexibility. The Company believes that the ICS agreement will mitigate its credit risk as it relates to uninsured FDIC amounts in excess of $250,000. At March 31, 2026 and December 31, 2025, the Company’s balances exceeded federally insured limits by approximately $1,001,505 and $1,701,861, respectively.

Accounts Receivable

Accounts receivable are recorded at the invoiced amount, which is the amount the Company expects to collect from its customers. Generally, payment is due from customers within 30-90 days of the invoice date. On a regular basis, the Company evaluates its accounts receivable and establishes the allowance for credit losses based on an evaluation of certain criteria and evidence of collection uncertainty including historical collection trends, reasonable expectations of future collections, current economic trends and changes in customer payment patterns. Past-due receivable balances are written off when the Company’s collection efforts have been deemed unsuccessful. The Company maintains an allowance for credit losses to reserve for potential uncollectible receivables. The allowance for credit losses as of March 31, 2026 and December 31, 2025 are as follows:

	March 31, 2026			December 31, 2025
Beginning balance	$	61,675		$	64,000
Provision (recovery) for credit losses		(868	)		230,190
Related allowances for written off accounts receivable		-			(152,568	)
Reversal of allowance related to reinstated invoices previously charged off		-			(82,000	)
Others		-			2,053
Ending balance	$	60,807			61,675

Credit Concentration

The concentration of credit risks in accounts receivable is due to several large customers comprising the Company’s customer base throughout North America. The Company maintains policies over credit extension that include credit evaluations, credit limits and collection monitoring procedures on a customer-by-customer basis. However, the Company generally does not require collateral before services are performed.

The Company has several customers for the three months ended March 31, 2026 and 2025 that make up in excess of 10% of revenue as follows:

	Three months ended
Customer	March 31, 2026			March 31, 2025
1		67	%		56	%
2		13	%		14	%

Inventory

Inventory is stated at the lower of cost (using the first-in, first-out method (“FIFO”)) or net realizable value. We continually analyze our slow moving and excess inventories. Based on historical and projected sales volumes and anticipated selling prices, we determined that establishing a reserve was not necessary at this time. Inventory that is in excess of current and projected use is reduced by an allowance to a level that approximates its estimate of future demand. Products that are determined to be obsolete are written down to net realizable value. The Company’s inventory is comprised of raw materials for a customer’s packaging needs as follows:

	March 31, 2026		December 31, 2025
Raw materials	$	218,076	$	243,285

Property and Equipment

Property and equipment, net is stated at cost less accumulated depreciation. Expenditures for major renewals and improvements which extend the life or usefulness of the asset are capitalized. Items of an ordinary repair or maintenance nature are charged directly to operating expense as incurred. During the construction and development period of an asset, the costs incurred, including interest expense, are classified as construction-in-progress. When the asset is ready for its intended use, the asset is reclassified to an appropriate asset classification and depreciation, or amortization commences.

The Company depreciates and amortizes the capitalized cost of these assets, using the straight-line method as follows:

Asset Classification:

Computer equipment 3-5 years

Furniture and fixtures 5-8 years

Leasehold Improvements Limited to lease term

The Company recognized depreciation expense of $37,379 and $37,857 for the three months ended March 31, 2026 and 2025, respectively, in its condensed consolidated statements of operations, respectively. Fully depreciated assets are retained in property, plant and equipment and accumulated depreciation until they are removed from service.

The Company tests for impairment whenever events or changes in circumstances indicate that the carrying value may not be recoverable. An impairment in the carrying value of long-lived assets is recognized if the expected future undiscounted cash flows derived from the assets, or group of assets, are less than their carrying value. The Company did not record any impairment charges related to long-lived assets in the periods presented.

Revenue Recognition

The Company recognizes revenue when control of the promised goods or services is transferred to the Company’s customers. Revenue is recorded at the transaction price, which is the amount that reflects the consideration the Company expects to receive in exchange for providing the goods or services. The Company’s primary performance obligations in our contracts with customers are to provide services related to emergency preparedness or to deliver specialty packaging. Most of the Company’s revenues are for services, which are recognized over time as the related time and materials are incurred at contractually agreed-upon rates. Product revenues are recognized at a point in time when the products are delivered and control transfers to the customer. The Company’s payment terms vary by the type of customers and the products or services offered. The periods between invoicing and when payments are due are not significant. Amounts billed to customers related to shipping and handling are classified as revenue, and the Company’s shipping and handling costs are included in costs of revenues.

Disaggregation of Revenue

The following table presents our disaggregated revenues by distribution channel:

	Three Months Ended March 31,
Sales by distribution channel:	2026		2025
Emergency preparedness	$	878,596	$	941,721
Specialty packaging		227,547		507,656
Total	$	1,106,143	$	1,449,377

	Three Months Ended March 31,
Sales by customer type:	2026		2025
Governmental	$	884,667	$	1,078,501
Non-governmental		221,476		370,876
Total	$	1,106,143	$	1,449,377

Emergency preparedness

We provide comprehensive services primarily to state and local governments. These services include managing their building sites, medical stockpiles of equipment, supplies and responding to state or local emergencies. We also provide Quality Control/Assurance to safeguard vaccines, medical supplies, and equipment. Revenue is recognized when services are rendered, or medical supplies are shipped.

Specialty Packaging.

Our specialty temperature-regulating packaging solutions provide a better thermal system to maintain and protect products and ensure peak customer experience. In utilizing this packaging, customers yield the benefits of lower costs and overhead while improving process, agility, velocity, accuracy, and repeatability of complex fulfillment networks. Revenue is recorded when products are delivered, or services are rendered. Additionally, it also includes amounts billed to customers related to shipping and handling are classified as revenue and the Company’s shipping and handling costs are included in costs of revenues as well as the Company’s contract with a customer for cloud-based temperature monitoring software. The customer paid their contract in advance and therefore revenue is earned monthly over the term of the contract.

Stock Warrants

During the first quarter ended March 31, 2025, the Company granted 72,179 stock warrants to various individuals of the underwriting firm that assisted the Company with its initial public offering on February 4, 2025. The stock warrants were issued in lieu of cash for a portion of their services. There were no warrants issued during the first quarter ended March 31, 2026. The Company accounts for its warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in ASC 480, “Distinguishing Liabilities from Equity” and ASC 815, “Derivatives and Hedging”. The assessment considers whether the warrants are freestanding financial instruments that would require classification as a liability under ASC 480, as well as whether the warrants qualify for equity classification or require liability classification after consideration of the guidance and criteria outlined in ASC 815, including whether the warrants are indexed to the Company’s own common shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions that impact classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance. For issued warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. As of March 31, 2026, the Company’s condensed consolidated balance sheet included equity classified warrants, reported as additional paid in capital.

Share-Based Compensation

The Company provides share-based compensation to its employees and Board of Directors. The Company is required to exercise judgment and make estimates when determining the (i) fair value of each award granted and (ii) projected number of awards expected to vest. The Company calculates the fair value of all share-based awards at the date of grant using the Black-Scholes option-pricing model for stock options and Monte Carlo simulation model for market-based awards. The Company uses the straight-line method to amortize this fair value as compensation cost over the requisite service period. Any forfeitures are recognized as they occur.

Net Loss per Common Share

The following table sets forth the number of potential shares of common stock that have been excluded from diluted net loss per share because their effect was anti-dilutive for the three months ended March 31, 2026 and March 31, 2025:

	Three Months ended
	March 31,
	2026		2025
Stock Options		1,287,500		1,275,000
Restricted Stock Awards		531,250		531,250
Stock Warrants		72,179		72,179
Total		1,890,929		1,878,429

Cost of Revenues

Our cost of revenue primarily includes the amounts paid to outside service providers, monitoring, direct and indirect labor, warehouse rent and other related expenses.

Advertising Expense

Advertising costs primarily consist of trade shows, other promotional expenses and the cost to retain our marketing firm. Advertising costs are expensed as incurred. Advertising expense for the three months ended March 31, 2026 and 2025 was $75,250 and $140,949, respectively.

Fair Value of Financial Instruments

The Company accounts for its derivative instruments in accordance with the provisions of Accounting Standards Codification (“ASC”) 820-10, Fair Value Measurement, which among other things provides the framework for measuring fair value. That framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level I measurement) and the lowest priority to unobservable inputs (Level III measurements). The three levels of fair value hierarchy under ASC 820-10, Fair Value Measurement, are as follows:

Level I - Quoted prices are available in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date.

Level II - Significant observable inputs other than quoted prices in active markets for which inputs to the valuation methodology include: (1) Quoted prices for similar assets or liabilities in active markets; (2) Quoted prices for identical or similar assets or liabilities in inactive markets; (3) Inputs other than quoted prices that are observable; and (4) Inputs that are derived principally from or corroborated by observable market data by correlation or other means. If the asset or liability has a specified (contractual) term, the Level II input must be observable for substantially the full term of the asset or liability.

Level III - Significant unobservable inputs that reflect an entity’s own assumptions that market participants would use in pricing the assets or liabilities.

The asset or liability fair value measurement level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement.

The Company’s financial instruments primarily consist of cash and cash equivalents, accounts receivable, accounts payable and derivative liabilities.

The carrying amounts of cash and cash equivalents, accounts receivable, and accounts payable approximate their respective fair values because of the short-term maturities or expected settlement dates of these instruments.

The derivative liability is valued using a Monte Carlo simulation model utilizing a variety of inputs and assumptions such as volatility, risk-free rates, volume weighted average price and cash flow assumptions. This is considered a Level III valuation technique. Please see Note 6, “Equity – Equity Line of Credit” for information on these assumptions and fair value of this derivative liability as of March 31, 2026.

	March 31, 2026		Level 1		Level 2		Level 3
Derivative liability at fair value	$	709,445	$	—	$	—	$	709,445
Total liability measured at fair value	$	709,445	$	—	$	—	$	709,445

Deferred Revenue

Deferred revenue represents customer billings for services that are not yet rendered and is primarily related to a customer invoice billed before service was rendered and for billings of annual or multi-year service contracts. As of March 31, 2026 and December 31, 2025, the Company has no deferred revenue that can be recognized over the next year.

Income Tax

The Company provides for income taxes and the related accounts under the asset and liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities using enacted tax rates expected to be in effect during the year in which the basis differences reverse. Valuation allowances are established when management determines it is more likely than not that some portion, or all, of the deferred tax assets will not be realized.

Leases

The Company’s leases predominantly relate to real estate equipment, such as vehicles and industrial equipment utilized in operations. Contracts are reviewed at inception to determine if the arrangement is a lease. The Company generally enters into long-term real estate leases with one to ten-year terms. In the normal course of business, the Company also enters into short-term leases having terms of one year or less. These leases are generally equipment leases entered into for short periods of time (e.g., daily, weekly, or monthly) to satisfy immediate and/or short-term operational needs of the business which can arise based upon the nature of particular services performed. The Company has elected not to recognize right-of-use (“ROU”) assets and lease liabilities for these short-term leases. Operating leases with terms exceeding one year are recognized as ROU assets and lease liabilities and measured at the commencement date based on the present value of the future lease payments over the lease term. Certain of the Company’s real estate leases contain escalating future lease payments. Escalating lease payments that are based upon explicit amounts contained in the lease or an index (e.g., consumer price index) are included in the Company’s determination of future lease payments to determine the ROU asset and lease liability recognized at the commencement date. Any differences in the future lease payments from initial recognition are not anticipated to be material and will be recorded as variable lease cost in the period incurred. The variable lease cost will also include the Company’s portion of property tax, utilities, and common area maintenance. A significant portion of the Company’s real estate lease agreements include renewal periods at the Company’s option. The Company includes these renewal periods in the lease term only when renewal is reasonably certain based upon facts and circumstances specific to the lease and known by the Company. The Company uses its incremental borrowing rate available at the lease commencement date in determining the present value of future lease payments as the implicit rate is typically not readily determinable. For operating leases, lease cost is recognized on a straight-line basis over the lease term and is included in cost of revenues or selling, general and administrative expenses depending on the use of the asset. As of March 31, 2026 and December 31, 2025, the Company did not have any leases that were classified as finance leases.

Recent Accounting Pronouncements

In November 2024, the FASB issued ASU 2024-03, Income Statement Reporting-Comprehensive Income-Expense Disaggregation Disclosures (Subtopic 220-40), Disaggregation of Income Statement Expenses. The standard update improves the disclosures about a public business entity’s expenses by requiring more detailed information about certain types of costs and expenses in the notes to the financial statements. The guidance will be effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The standard updates are to be applied prospectively, with the option to apply them retrospectively. We are currently evaluating the impact of the new standard’s disclosure requirements on our financial statements.

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. This standard introduces a practical expedient for the application of the current expected credit loss (“CECL”) model to current accounts receivable and contract assets. ASU 2025-05 is effective for annual periods beginning after December 15, 2025 and interim periods within those annual periods. The Company adopted ASU 2025-05 for the fiscal year and interim period beginning January 1, 2026 and elected the practical expedient. The adoption did not have a material impact on the consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU No. 2025-11, “Interim Reporting – Narrow-Scope Improvements,” which is intended to improve the navigability of previous guidance and clarify when that guidance is applicable. Among other items, it establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is not intended to change the fundamental nature of interim reporting or expand or reduce current interim disclosure requirements. The guidance may be applied retrospectively or prospectively and will be effective for the Company for interim periods beginning in fiscal year 2028. The Company is currently evaluating the impact of this ASU but does not anticipate this adoption to have a material impact on the Company’s financial statements.

The FASB issues ASUs to amend the authoritative literature in ASC. There have been a number of ASUs to date, including those above, that amend the original text of ASC. Management believes that those issued to date either (i) provide supplemental guidance, (ii) are technical corrections, (iii) are not applicable to us or (iv) are not expected to have a significant impact on our consolidated financial statements.
