Notes to Condensed Financial Statements (Unaudited) Note 1. Interim Financial Reporting Basis of presentation: Electromed, Inc. (the “Company”) develops, manufactures and markets innovative airway clearance products that apply High Frequency Chest Wall Oscillation (“HFCWO”) therapy in pulmonary care for patients of all ages. The Company markets its products in the U.S. to the home health care and institutional markets for use by patients in personal residences, hospitals and clinics. The Company also sells internationally both directly and through distributors. International sales were $ 432,000 and $ 297,000 for the nine months ended March 31, 2022 and 2021, respectively. Since its inception, the Company has operated in a single industry segment: developing, manufacturing and marketing medical equipment. The accompanying unaudited Condensed Financial Statements of the Company have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial statements and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. In the opinion of management, the accompanying unaudited Condensed Financial Statements reflect all adjustments consisting of normal recurring adjustments necessary for a fair presentation of the Company’s financial position and results of operations as required by Regulation S-X. Interim results of operations are not necessarily indicative of the results that may be achieved for the full year. The financial statements and related notes do not include all information and footnotes required by U.S. GAAP for annual reports. This interim report should be read in conjunction with the financial statements included in the Company’s Annual Report on Form 10-K for the fiscal year ended June 30, 2021 (“fiscal 2021”). Impacts of COVID-19 on the Company’s business: The impact of the COVID-19 pandemic on the Company’s business remains uncertain, and its effects on our operational and financial performance will depend in large part on future developments, which cannot be reasonably estimated at this time. Such future developments include, but are not limited to, the duration, scope and severity of the COVID-19 pandemic in geographic areas where the Company operates or in which its patients live, actions taken to contain or mitigate its impact, the impact on governmental healthcare programs and budgets, the development and distribution of treatments or vaccines, and the resumption of widespread economic activity. Due to the inherent uncertainty of the unprecedented and rapidly evolving situation, the Company is unable to predict with confidence the likely impact of the COVID-19 pandemic on its future operations. For a more detailed discussion, see “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in Part I, Item 2 of this Quarterly Report on Form 10-Q. A summary of the Company’s significant accounting policies follows: Use of estimates . Management uses estimates and assumptions in preparing the unaudited Condensed Financial Statements in accordance with U.S. GAAP. Those estimates and assumptions affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported revenues and expenses. Actual results could vary from the estimates that were used. The Company believes the critical accounting policies that require the most significant assumptions and judgments in the preparation of its unaudited Condensed Financial Statements include revenue recognition and the related estimation of variable consideration, inventory valuation, share-based compensation and warranty reserve. Net income per common share . Net income is presented on a per share basis for both basic and diluted common shares. Basic net income per common share is computed using the weighted average number of common shares outstanding during the period, excluding any restricted stock awards which have not vested. The diluted net income per common share calculation includes outstanding restricted stock grants and assumes that all stock options were exercised and converted into common stock at the beginning of the period unless their effect would be anti-dilutive. Common stock equivalents excluded from the calculation of diluted earnings per share because their impact was anti-dilutive were 102,435 and 52,017 for the three months ended March 31, 2022 and 2021, respectively, and were 112,427 and 52,017 for the nine months ended March 31, 2022 and 2021, respectively. 5 Note 2. Revenues Revenue is measured based on consideration specified in the contract with a customer, adjusted for any applicable estimates of variable consideration and other factors affecting the transaction price, including consideration paid or payable from customers and significant financing components. Revenue from all customers is recognized when a performance obligation is satisfied by transferring control of a distinct good or service to a customer, as further described below under Performance obligations and transaction price . Individual promised goods and services in a contract are considered a performance obligation and accounted for separately if the individual good or service is distinct (i.e., the customer can benefit from the good or service on its own or with other resources that are readily available to the customer and the good or service is separately identifiable from other promises in the arrangement). If an arrangement includes multiple performance obligations, the consideration is allocated between the performance obligations in proportion to their estimated standalone selling price, unless discounts or variable consideration is attributable to one or more but not all the performance obligations. Costs related to products delivered are recognized in the period incurred, unless criteria for capitalization of costs under Accounting Standards Codification (“ASC”) 340-40, “Other Assets and Deferred Costs” (“ASC 340”), or other applicable guidance are met. The Company includes shipping and handling fees in net revenues. Shipping and handling costs associated with the shipment of the Company’s SmartVest® Airway Clearance System (“SmartVest System”) after control has transferred to a customer are accounted for as a fulfillment cost and are included in cost of revenues in the Condensed Statements of Operations. The timing of revenue recognition, billings and cash collections results in accounts receivable on the Condensed Balance Sheets as further described below under Accounts receivable and Contract assets . Disaggregation of revenues. In the following table, net revenues are disaggregated by market: Schedule of disaggregated revenue Three Months Ended March 31, Nine Months Ended March 31, 2022 2021 2022 2021 Home care $ 9,033,000 $ 8,163,000 $ 27,721,000 $ 24,529,000 Institutional 392,000 443,000 1,174,000 1,029,000 Home care distributor 520,000 105,000 1,063,000 432,000 International 196,000 76,000 432,000 297,000 Total $ 10,141,000 $ 8,787,000 $ 30,390,000 $ 26,287,000 In the following table, net home care revenue is disaggregated by payer type: Three Months Ended March 31, Nine Months Ended March 31, 2022 2021 2022 2021 Commercial $ 3,358,000 $ 3,111,000 $ 10,738,000 $ 9,212,000 Medicare 5,027,000 4,622,000 15,603,000 14,224,000 Medicaid 373,000 316,000 790,000 669,000 Other 275,000 114,000 590,000 424,000 Total $ 9,033,000 $ 8,163,000 $ 27,721,000 $ 24,529,000 Revenues in the Company’s home care, home care distributor, and international markets are recognized at a point-in-time when control passes to the customer upon product shipment or delivery. Revenues in the Company’s institutional market include revenue recognized at a point-in-time upon shipment or delivery as well as revenue recognized over time under operating leases. Performance obligations and transaction price. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is the unit of account under ASC 606, “Revenue From Contracts With Customers” (“ASC 606”). A contract’s transaction price is allocated to each distinct performance obligation in proportion to the standalone selling price for each and recognized as revenue when, or as, the performance obligation is satisfied. The Company’s performance obligations and the timing or method of revenue recognition in each of the Company’s markets are discussed below: Home care market . In the Company’s home care market, its customers are patients who use the SmartVest System. The various models of the SmartVest System are comprised of three main components - a generator, a vest and a connecting hose - that are sold together as an integrated unit. Accordingly, in contracts within the home care market, the Company regards the SmartVest System to be a single performance obligation. 6 The Company makes available to its home care patients limited post-sale services that are not material in the context of the contracts, either individually or taken together, and therefore does not consider them to be performance obligations. The costs associated with the services are accrued and expensed when the related revenues are recognized. As such, transactions in the home care market consist of a single performance obligation: the SmartVest System. Home care patients generally will rely on third-party payers, including commercial payers and governmental payers such as Medicare, Medicaid and the U.S. Department of Veterans Affairs to cover and reimburse all or part of the cost of the SmartVest System. The third-party payers’ reimbursement programs fall into three types, distinguished by the differences in the timing of payments from the payer, consisting of either (i) outright sale, in which payment is received from the payer based on standard terms, (ii) capped installment sale, under which the SmartVest System is sold for a series of payments that are capped not to exceed a prescribed or negotiated amount over a period of time or (iii) installment sale, under which the SmartVest System is paid for over a period of several months as long as the patient continues to use the SmartVest System. Regardless of the type of transaction, provided criteria for an enforceable contract are met, it is the Company’s long- standing business practice to regard all home care agreements as transferring control to the patient upon shipment or delivery, in spite of possible payment cancellation under government or commercial programs where the payer is controlling the payment over specified time periods. For home care sales that feature installment payments, the ultimate amount of consideration received from Medicare, Medicaid or commercial payers can be significantly less than expected if the contract is terminated due to changes in the patient’s status, including insurance coverage, hospitalization, death or otherwise becoming unable to use the SmartVest System. However, once delivered to a patient who needs the SmartVest System, the patient is under no obligation to return the SmartVest System should payments be terminated as a result of the described contingencies. As a result, the Company’s product sales qualify for point-in-time revenue recognition. Control transfers to the patient, and revenue is recognized, upon shipment of the SmartVest System. At this point, physical possession and the significant risks and rewards of ownership are transferred to the patient and either a current or future right to payment is triggered, as further discussed under Accounts receivable and Contract assets below. The Company’s contractually stated transaction prices in the home care market are generally set by the terms of the contracts negotiated with insurance companies or by government programs. The transaction price for the Company’s products may be further impacted by variable consideration. ASC 606 requires the Company to adjust the transaction price at contract inception and throughout the contract duration for the estimated value of payments to be received from insurance payers based on historical experience and other available information, subject to the constraint on estimates of variable consideration. Transactions requiring estimates of variable consideration primarily include (i) capped installment payments, which are subject to the third-party payer’s termination due to changes in insurance coverage, death or the patient’s discontinued use of the SmartVest System, (ii) contracts under appeal and (iii) patient responsibility amounts for deductibles, coinsurance, copays and other similar payments. Although estimates may be made on a contract-by-contract basis, whenever possible, the Company uses all available information, including historical collection patterns, to estimate variable consideration for portfolios of contracts. The Company’s estimates of variable consideration consist of amounts it may receive from insurance providers in excess of its initial revenue estimate due to patients meeting deductibles or coinsurance during the payment duration, changes to a patient’s insurance status, changes in an insurance allowable, claims in appeals with Medicare and amounts received directly from patients for their allowable or coinsurance. The Company believes it has representative historical information to estimate the amount of variable consideration in relevant portfolios considering the significant experience it has with each portfolio and the similarity of patient accounts within a portfolio. The analysis includes steps to ensure that revenue recognized on a portfolio basis does not result in a material difference when compared with an individual contract approach. The Company also leverages its historical experience and all available relevant information for each portfolio of contracts to minimize the risk its estimates used to arrive at the transaction price will result in a significant reversal in the amount of cumulative revenue recognized when the uncertainty associated with the variable consideration is subsequently resolved. Variable consideration is included in the transaction price if, in the Company’s judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. For example, for contracts in which the Company believes the criteria for reimbursement under government or commercial payer contracts have been met but for which coverage is unconfirmed or payments are under appeal, the Company has significant observable evidence of relatively consistent claims recovery experience over the prior three to five years. The Company believes the low volatility in historical claims approval rates for populations of patients whose demographics are similar to those of current patients provides reliable predictive value in arriving at estimates of variable consideration in such contracts. Similarly, historical payment trends for recovery of claims subject to payer installments and payments from patients have remained relatively consistent over the past five years. No significant changes in patient demographics or other relevant factors have occurred that would limit the predictive value of such payment trends in estimating variable consideration for current contracts. As a result, the Company believes its estimates of variable consideration are generally not subject to the risk of significant revenue reversal. 7 For each type of variable consideration discussed above, there are a large number of contracts with similar characteristics with a wide range of possible transaction prices. For that reason, the Company uses the probability-weighted expected value method provided under ASC 606 to estimate variable consideration. The Company often receives payment from third-party payers for SmartVest System sales over a period of time that may exceed one year. Despite these extended payment terms, no significant financing component is deemed to exist because the purpose of such terms is not to provide financing to the patient, the payer or the Company. Rather, the extended payment terms are mandated by the government or commercial insurance programs; the fundamental purpose of which is to avoid paying the full purchase price of equipment that may potentially be used by the patient for only a short period of time. Home care distributors. Sales to distributors, who sell direct to patients, are made at fixed contract prices and may include tiered pricing structures or volume-based rebates which offer more favorable pricing once certain volumes are achieved per the negotiated contract. The distributor’s purchases accumulate to give the distributor a right to a higher discount on purchases in excess of the specified level within the contract period. As a result, to the extent the Company expects the distributor to exceed the specified volume of purchases in the annual period, it recognizes revenue at a blended rate based on estimated total annual volume and sales revenue. This effectively defers a portion of the transaction price on initial purchases below the specified volumes for recognition when the higher discount is earned on purchases in excess of specified volumes. Transfer of control of the products occurs upon shipment or delivery to the distributor, as applicable. Institutional market. The Company’s institutional sales are made to hospitals and home health care centers, pulmonary rehabilitation centers and other clinics. Sales to these institutions are negotiated with the individual institution or with group purchasing organizations, with payments received directly from the institution. No insurance reimbursement is involved. Generators are either sold or leased to the institutions and associated hoses and wraps (used in institutional settings rather than vests) are sold separately. Accordingly, each product is distinct and considered a separate performance obligation in sales to institutional customers. The agreements with institutions fall into two main types, distinguished by differences in the timing of transfer of control and timing of payments: ● Outright sale – Under these transactions, the Company sells its products for a prescribed or negotiated price. Transfer of control of the product, and associated revenue recognition, occurs at the time of shipment and payment is made within normal credit terms, usually thirty days. ● Wrap usage agreements – Under these transactions, the Company provides a generator device at no cost to the hospital in return for a fixed annual commitment to purchase consumable wraps. These agreements are cancellable upon at least sixty days prior written notice by either party. If cancelled, the generator is returned to the Company, where it can be refurbished and used again at a later date. Revenue for the consumable wraps is recognized when control transfers to the customer. International market. Sales to international markets are made directly to a number of independent distributors at fixed contract prices that are not subject to further adjustments for variable consideration. Transfer of control of the products occurs upon shipment or delivery to the distributor, as applicable. Product warranty. The Company offers warranties on its products. These warranties are assurance-type warranties not sold on a standalone basis or are otherwise considered immaterial in the context of the contract, and therefore are not considered distinct performance obligations under ASC 606. The Company estimates the costs that may be incurred under its warranties and records a liability in the amount of such costs at the time the product is sold. Accounts receivable. The Company’s accounts receivable balance is comprised of amounts due from individuals, institutions and distributors. Balances due from individuals are typically remitted to the Company by third-party reimbursement agencies such as Medicare, Medicaid and private insurance companies. Accounts receivable are carried at amounts estimated to be received from patients under reimbursement arrangements with third-party payers. Accounts receivable are also net of an allowance for doubtful accounts. Management determines the allowance for doubtful accounts by regularly evaluating individual customer receivables and considering a customer’s financial condition and credit history. Receivables are written off when deemed uncollectible. 8 Contract assets. Contract assets include amounts recognized as revenue that are estimates of variable consideration for Medicare appeals where the final determination of the insurance coverage amount is dependent on future approval of an appeal, or when the consideration due to the Company is dependent on a future event such as the patient meeting a deductible prior to the Company’s claim being processed by the payer. Contract assets are classified as current as amounts will turn into accounts receivable and be collected during the Company’s normal business operating cycle. Contract assets are reclassified to accounts receivable when the right to receive payment is unconditional. Contract balances. The following table provides significant changes in contract assets from contracts with customers: Schedule of contract assets Nine Months Ended March 31, 2022 Fiscal Year Ended June 30, 2021 Increase (decrease) Increase (decrease) Contract assets, beginning $ 393,000 $ 903,000 Reclassification of contract assets to accounts receivable ( 169,000 ) ( 1,551,000 ) Contract assets recognized 151,000 1,060,000 Decrease as a result of changes in the estimate of amounts to be realized from payers, excluding amounts transferred to receivables during the period ( 80,000 ) ( 19,000 ) Contract assets, ending $ 295,000 $ 393,000 Incremental costs to obtain a contract. Sales incentives paid to sales representatives are eligible for capitalization as they are incremental costs that would not have been incurred without entering into a specific sales arrangement and are recoverable through the expected margin on the transaction. However, the recovery period is less than one year as the performance obligation is satisfied upon shipment or delivery. Consequently, the Company applies the practical expedient provided by ASC 340 and expenses sales incentives as incurred. These costs are included in selling, general and administrative expenses in the Condensed Statements of Operations. Note 3.

Warranty Reserve The Company provides a lifetime warranty on its products to the prescribed patient for sales within the U.S. and a three-year warranty for all institutional sales and sales to individuals outside the U.S. The Company estimates the costs that may be incurred under its warranty and records a liability in the amount of such costs at the time the product is shipped. Factors that affect the Company’s warranty reserve include the number of units shipped, historical and anticipated rates of warranty claims, the product’s useful life and cost per claim. The Company periodically assesses the adequacy of its recorded warranty reserve and adjusts the amounts as necessary. 9 Changes in the Company’s warranty reserve were as follows: Schedule of changes in warranty liability Nine Months Ended March 31, 2022 Fiscal Year Ended June 30, 2021 Warranty reserve, beginning $ 940,000 $ 740,000 Accrual for products sold 122,000 354,000 Expenditures and costs incurred for warranty claims ( 124,000 ) ( 154,000 ) Warranty reserve, ending $ 938,000 $ 940,000 Note 5.

Estimated income tax expense for the nine months ended March 31, 2021 included such $ 37,000 discrete tax benefit as well as a $ 32,000 discrete tax benefit related to the exercise of stock options. The net impact of these discrete events decreased the estimated effective tax rates by 2.7 % during the nine months ended March 31, 2021. The Company is subject to U.S. federal and state income tax in multiple jurisdictions. With limited exceptions, years prior to the Company’s fiscal year ended 2019 are no longer open to U.S. federal, state or local examinations by taxing authorities. The Company is currently under examination by the Internal Revenue Service (the “IRS”) for the fiscal year ended June 30, 2020. To date, the IRS is continuing its examination process and no formal assessments have been issued. The Company is not under any current income tax examinations by any other state or local taxing authority. If any issues addressed in the Company’s tax audits are resolved in a manner not consistent with management’s expectations, the Company could be required to adjust its provision for income taxes in the period such resolution occurs. Note 6. Financing Arrangements The Company has a credit facility that provides for a revolving line of credit. Effective December 17, 2021 , the Company renewed its $ 2,500,000 revolving line of credit. There was no outstanding principal balance on the line of credit as of March 31, 2022, or June 30, 2021. Interest on borrowings under the line of credit, if any, accrues at the prime rate ( 3.50 % at March 31, 2022) less 1.0 % and is payable monthly. The amount eligible for borrowing on the line of credit is limited to the lesser of $ 2,500,000 or 57.0 % of eligible accounts receivable and the line of credit expires on December 18, 2023 , if not renewed before such date. At March 31, 2022, the maximum $ 2,500,000 was eligible for borrowing. Payment obligations under the line of credit, if any, are secured by a security interest in substantially all of the tangible and intangible assets of the Company. The documents governing the line of credit contain certain financial and nonfinancial covenants that include a minimum tangible net worth covenant of not less than $ 10,125,000 and restrictions on the Company’s ability to incur certain additional indebtedness or pay dividends.

Note 8. Commitments and Contingencies The Company is occasionally involved in claims and disputes arising in the ordinary course of business. The Company insures certain business risks where possible to mitigate the financial impact of individual claims and establishes reserves for an estimate of any probable cost of settlement or other disposition. On September 8, 2021, a state court putative class action lawsuit was filed in Minnesota against the Company asserting injury resulting from the previously announced data breach that impacted the Company’s customer protected health information and employee personal information and seeking compensatory damages, equitable relief and attorneys’ fees and costs. On October 6, 2021, the proceeding was removed to the District of Minnesota. The Company believes the plaintiff was not injured as a result of the data privacy incident, and, as a result, the claims are without merit. Accordingly, on November 11, 2021, the Company moved to dismiss the complaint in its entirety, and the hearing on such motion is currently set for May 2022. The Company expects to continue to vigorously defend the lawsuit; however, it is currently unable to determine the ultimate outcome or potential exposure to loss, if any. 11
