KORU Medical Systems, Inc.

NOTES TO THE UNAUDITED FINANCIAL STATEMENTS

NOTE 1 —NATURE OF OPERATIONS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

NATURE OF OPERATIONS

KORU MEDICAL SYSTEMS, INC. (the “Company,” “KORU Medical,” “KORU,” “we,” “us” or “our”) develops, manufactures and commercializes innovative and patient-centric large volume subcutaneous infusion solutions primarily for the subcutaneous drug delivery market as governed by the United States Food and Drug Administration (the “FDA”) quality and regulatory system and international standards for quality system management. The Company operates as one segment.

BASIS OF PRESENTATION

The accompanying financial statements should be read in conjunction with the Company’s annual report on Form 10-K for the year ended December 31, 2025 (“Annual Report”). In accordance with the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”), the Company has omitted footnote disclosures that would substantially duplicate the disclosures contained in the audited financial statements of the Company. The accompanying interim financial statements are unaudited and reflect all adjustments which are in the opinion of management necessary for a fair statement of the Company’s financial position, results of operations, and cash flows for the periods presented. All such adjustments are of a normal, recurring nature. The Company’s results of operations and cash flows for the interim periods are not necessarily indicative of the results of operations and cash flows that it may achieve in future periods.

CASH AND CASH EQUIVALENTS

For purposes of the statements of cash flows, the Company considers all short-term investments with an original maturity of three months or less to be cash equivalents. As of March 31, 2026 the Company held cash and cash-equivalents of $8.8 million, the majority of which was held in a secured US-treasury money market fund.

PATENTS

Costs incurred in obtaining patents have been capitalized and are being amortized over the legal life of the patents.

STOCK-BASED COMPENSATION

The Company maintains an omnibus equity incentive plan under which it grants options and other equity incentive awards to certain executives, employees and consultants, as well as shares of common stock to non-employee directors.

The fair value of each stock option grant is estimated on the date of the grant using the Black-Scholes option-pricing model. All options are charged against income at their fair value. The entire compensation expense of the award is recognized over the vesting period.

Shares of stock granted for director fees are recorded at the fair value of the shares at the grant date.

Restricted stock awards are equity classified and measured at the fair market value of the underlying stock at the grant date. The fair value of restricted stock awards vesting at certain market capitalization thresholds were estimated on the date of grant using the Brownian Motion Monte Carlo lattice model. The fair value of restricted stock awards with time-based vesting were estimated on the date of grant at the current stock price. The fair value of restricted stock awards vesting at certain annual sales growth thresholds were estimated as of the date of Board acknowledgement of the achievement, at the current stock price. We recognize restricted stock expense using the straight-line attribution method over the requisite service period and account for forfeitures as they occur.

Restricted stock units (“RSUs”) and performance stock units (“PSUs”) are equity classified and measured at the fair market value of the underlying stock at the grant date.

NET LOSS PER SHARE

The Company computes net loss per share using the weighted-average number of common shares outstanding during the period. Basic and diluted net loss per share are the same because the conversion, exercise or issuance of all potential common stock equivalents, which comprise the Company’s outstanding common stock options, unvested restricted stock units, performance stock units and warrants, would be anti-dilutive, due to the reporting of a net loss for each of the periods in the accompanying statements of operations.

USE OF ESTIMATES IN THE FINANCIAL STATEMENTS

The preparation of financial statements in conformity with United States generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results could differ from those estimates. Important estimates include but are not limited to asset lives, deferred tax valuation allowances, inventory valuation, expected credit losses, and customer rebate and incentive accruals. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results that may be expected for the entire 2026 fiscal year.

REVENUE RECOGNITION

Our revenues are derived from three business sources: (i) domestic core (which consists of US and Canada), (ii) international core, and (iii) pharma services and clinical trials. Our domestic and international core revenues consist of sales of our syringe drivers, tubing and needles (“Product Revenue”) for the delivery of subcutaneous drugs that are FDA cleared for use with the KORU Medical infusion system, with the primary delivery for immunoglobulin to treat Primary Immunodeficiency Diseases (“PIDD”) and Chronic Inflammatory Demyelinating Polyneuropathy (“CIDP”). Pharma services and clinical trials consist of Product Revenue for feasibility/clinical trials (pre-clinical studies, Phase I, Phase II, Phase III) of biopharmaceutical companies in the drug development process as well as non-recurring engineering services (“NRE”) revenues (including testing and registration services) received from biopharmaceutical companies to ready or customize the FREEDOMTM System for clinical and commercial use across multiple drug categories.

For Product Revenue, we recognize revenues when shipment occurs, at which point the customer obtains control and ownership of the goods. Shipping costs generally are billed to customers and are included in Product Revenue.

The Company generally does not accept return of goods shipped unless it is a Company error. The only credits provided to customers are for defective merchandise. The Company warrants the syringe driver from defects in materials and workmanship under normal use and the warranty does not include a performance obligation. The costs under the warranty are expensed as incurred.

Rebates are provided to distributors for the difference in selling price to distributors and pricing specified to select customers. In addition, rebates are provided to customers for meeting growth targets. Provisions for both distributor pricing and customer growth rebates are variable consideration and are recorded as a reduction of revenue in the same period the related sales are recorded or when it is probable the growth target will be achieved.

We recognize NRE revenue under an input method, which recognizes revenue on the basis of our efforts or inputs (for example, resources consumed, labor hours expended, costs incurred, or time elapsed) to the satisfaction of a performance obligation relative to the total expected inputs to the satisfaction of that performance obligation (i.e. completion milestone). The input method that we use is based on costs incurred.

Contracts are often modified to account for changes in contract specifications and requirements. Contract modifications exist when the modification either creates new, or changes existing, enforceable rights and obligations. Generally, when contract modifications create new performance obligations, the modification is considered to be a separate contract and revenue is recognized prospectively. When contract modifications change existing performance obligations, the impact on the existing transaction price and measure of progress for the performance obligation to which it relates is generally recognized as an adjustment to revenue (either as an increase in or a reduction of revenue) on a cumulative catch-up basis. Contract assets primarily represent revenue earnings over time that are not yet billable based on the terms of the contracts. Contract liabilities (i.e., deferred revenue) consist of fees invoiced or paid by the Company’s customers for which the associated performance obligations have not been satisfied and revenue has not been recognized based on the Company’s revenue recognition criteria described above. The Company has recognized a contract asset, which is included in other receivables in the accompanying balance sheet, of $335,206 and $319,955 as of March 31, 2026 and December 31, 2025, respectively.

The following table summarizes net revenues from our distributors and direct customers by geography for the three months ended March 31, 2026, and 2025.

ACCOUNTING PRONOUNCEMENTS RECENTLY ADOPTED

The Company considers the applicability and impact of all recently issued accounting pronouncements. Recent accounting pronouncements not specifically identified in our disclosures are either not applicable to the Company or are not expected to have a material effect on our financial condition or results of operations.

IMPAIRMENT OF LONG-LIVED ASSETS

The Company reviews long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amount of the assets may not be fully recoverable. An impairment loss would be recognized when estimated undiscounted future cash flows expected to result from the use of the asset and its eventual disposition are less than the carrying amount. The impairment loss, if recognized, would be based on the excess of the carrying value of the impaired asset over its respective fair value. The Company did not record any impairment losses for the quarter ended March 31, 2026, nor March 31, 2025.

NOTE 4 —DEBT OBLIGATIONS

On March 8, 2024, the Company entered into a loan and security agreement with a large domestic banking institution, as lender, providing for a $5,000,000 revolving credit facility and a $5,000,000 term loan facility. Borrowings are secured by a first-priority lien on substantially all of the assets of the Company, subject to customary exceptions. On March 30, 2026 the loan and security agreement was amended to extend the maturity of the $5,000,000 revolver from December 31, 2026 to March 30, 2028, and extends the interest-only period of the $5,000,000 term loan from September 30, 2026 to June 30, 2027 with a possible further extension to December 31, 2027 upon the achievement of certain EBITDA milestones as set forth therein. The term loan maturity has been extended from December 1, 2028 to December 1, 2029. The amendment lowers the interest rate floor to 5.50% from 6.50% for the revolver and the term loan. The amendment removes the adjusted quick ratio covenant for both the term loan and the revolver. The adjusted quick ratio covenant for the revolver has been replaced with a remaining months liquidity covenant of at least twelve months, to be tested monthly beginning the first month the revolver is drawn on; provided, however, the Company will be in compliance if trailing three (3) month average Adjusted EBITDA (as defined in the revolver) is positive.

NOTE 6 —INCOME TAXES

For interim income tax reporting, the Company estimates its annual effective tax rate and applies it to fiscal year-to-date pretax loss, excluding unusual or infrequently occurring discrete items. Tax jurisdictions with losses for which tax benefits cannot be realized are excluded. The Company reported an income tax expense ofzero for the three months ended March 31, 2026, and 2025, which is lower than the statutory tax rate at 21% primarily due to the valuation allowance established against the net deferred tax assets.

We evaluate our deferred tax assets to determine if they are more likely than not to be realized by assessing both positive and negative evidence in accordance with ASC Topic 740, Income Taxes. After considering our cumulative pretax loss (the three-year period ended with the current year), as well as analyzing all available evidence, we maintained the full valuation allowance against our net deferred tax assets. As we continue to assess the realizability of our deferred tax assets, reported pretax income and new evidence may result in a partial or full reduction of the valuation allowance in future periods.

The Company files income tax returns in the U.S. federal jurisdiction and in various state jurisdictions. Income tax returns for years prior to fiscal 2022 are no longer subject to examination by tax authorities.
