ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

Overview

American Shared Hospital Services is a leading provider of turn-key technology solutions for stereotactic radiosurgery and advanced radiation therapy equipment and services. The main drivers of the Company’s revenue are numbers of sites, procedure volume, and reimbursement. The Company delivers radiation therapy through medical equipment leasing and direct patient services, its two reportable segments. The medical equipment leasing segment, which we also refer to as the Company’s leasing segment, operates by fee-per-use contracts or revenue sharing contracts where the Company shares in the revenue and operating costs of the equipment. The Company leases ten Gamma Knife systems and one PBRT system as of December 31, 2023, where a contract exists between the hospital and the Company. The Company, through GKF, also owns and operates two single-unit Gamma Knife facilities in Lima, Peru and Guayaquil, Ecuador. The Company’s facilities in Peru and Ecuador are considered direct patient services, which we also refer to as the Company’s retail segment, where a contract exists between the Company's facilities and the individual treated at the facility. A summary of the Company’s medical equipment leases and direct patient service sites is set forth in the table below:

Number of Sites

Revenue Sharing 5 6

Fee Per Use 5 6

Medical Equipment Leasing - Gamma Knife 10 12

Medical Equipment Leasing - Proton Bream Radiation Therapy 1 1

Medical Equipment Leasing - Total 11 13

Direct Patient Services ("Retail") - Gamma Knife 2 2

The Company had two contracts expire in the second and third quarters of 2023, respectively. The Company had a third contract up for renewal in 2023. This lease was extended and the equipment was upgraded to an Esprit during the fourth quarter. The Company has one customer contract that will expire in November 2024. A summary of the Company’s procedure volumes for fiscal years 2023 and 2022 are set forth in the table below.

Volume

Increase Increase

Medical Equipment Leasing - Gamma Knife 824 954 (130 ) (13.6 )%

Direct Patient Services ("retail") - Gamma Knife 371 332 39 11.7 %

PBRT Procedures (medical equipment leasing) 5,369 5,296 73 1.4 %

The decrease in Gamma Knife volume, under medical equipment lease, during 2023 was primarily due to the expiration of two contracts in the second and third quarters of 2023, respectively. Same center procedures decreased 4% compared to 2022 due to downtime for the upgrade of two Gamma Knife systems to the Esprit during the third and fourth quarters of 2023. The increase in Gamma Knife volume, under direct patient services, during 2023 was due to improved marketing and physician outreach at the Company’s international locations, offset by downtime to upgrade the Gamma Knife equipment in Ecuador to the Icon. The increase in PBRT volume was due to normal, cyclical fluctuations.

Reimbursement

CMS established a 2024 delivery code reimbursement rate of approximately $7,420 ($7,691 in 2023) for a Medicare Gamma Knife treatment. The approximate CMS reimbursement rates for delivery of PBRT for a simple treatment without compensation for 2024 is $561 ($572 in 2023) and $1,362 ($1,323 in 2023) for simple with compensation, intermediate and complex treatments, respectively.

On September 29, 2020, CMS published a final rule that would have implemented a new mandatory payment model for radiation oncology services delivered to certain Medicare beneficiaries: the RO APM. On August 29, 2022, CMS published a final rule that delayed the start date of the RO APM to a date to be determined through future rulemaking and amended the definition of “model performance period” to provide that the start and end dates of the five-year model performance period will be established by CMS through future rulemaking. If the RO APM had not been delayed, it would have significantly altered CMS’ payment methodology from a fee for service paradigm to a set reimbursement by cancer type methodology for radiation services provided within a 90 day episode of care. Under the RO APM, hospital based and free-standing radiation therapy providers would have been required to participate in the model based on whether the radiation therapy provider is located within a randomly selected core-based statistical area. At this time, it is not clear if the RO APM will be implemented and, if it is implemented, the timing for implementation and in what form it will be implemented. If a start date for the RO APM is proposed, CMS will provide at least six months’ notice in advance of the proposed start date, and the proposed start date will be subject to public comment.

Pending Acquisition

On November 10, 2023, the Company entered into the IPA with GenesisCare and GC Holdings pursuant to which GenesisCare agreed to sell to the Company its entire equity interest in each of RI Target Companies together with the assignment of certain payor contacts for a purchase price of $2,850,000. The equity interests to be acquired by the Company under the IPA equates to a 60% interest in each RI Target Company. The RI Target Companies operate three functional radiation therapy cancer centers in Rhode Island. The RI Acquisition is contingent upon certain closing conditions, including Genesis Care and the Company entering into a consent agreement with the Rhode Island Department of Health and approval of all equity holders and managers of each RI Target Company. On March 1, 2024, the Company, GenesisCare and GC Holding entered to a First Amendment to Investment Agreement pursuant to which the parties agreed to extend the date on which a party could terminate the IPA if the closing conditions had not been met from March 10, 2024 to April 30, 2024. The Company anticipates that the closing conditions will be met in April 2024.

APPLICATION OF CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The Company’s consolidated financial statements are prepared in accordance with generally accepted accounting principles and follow general practices within the industry in which it operates. Application of these principles requires management to make estimates, assumptions and judgments that affect the amounts reported in the consolidated financial statements and accompanying notes. These estimates, assumptions and judgments are based on information available as of the date of the consolidated financial statements; accordingly, as this information changes, consolidated the financial statements could reflect different estimates, assumptions and judgments. Certain policies inherently have a greater reliance on the use of estimates, assumptions and judgments and as such have a greater possibility of producing results that could be materially different than originally reported.

The most significant accounting policies followed by the Company are presented in Note 2 – Accounting Policies to the consolidated financial statements. These policies along with the disclosures presented in the other consolidated financial statement notes and, in this discussion, and analysis, provide information on how significant assets and liabilities are valued in the consolidated financial statements and how those values are determined. Based on the valuation techniques used and the sensitivity of the consolidated financial statement amounts, and the methods, assumptions and estimates underlying those amounts, management has identified revenue recognition and costs of sales for revenue sharing customers, and the salvage value of equipment, and as such the aforementioned could be most subject to revision as new information becomes available. The following are our critical accounting policies in which management’s estimates, assumptions and judgments most directly and materially affect the consolidated financial statements:

Revenue Recognition

The Company recognizes revenues under Accounting Standards Codification (“ASC”) 842 Leases (“ASC 842”) and ASC 606 Revenue from Contracts with Customers (“ASC 606”). The Company delivers radiation therapy through medical equipment leasing (“leasing”) and direct patient services (“retail”). The Company leased ten Gamma Knife systems and one PBRT system as of December 31, 2023. The leasing business operates by fee-per-use contracts or revenue sharing, where the Company shares in the revenue and operating costs of the equipment. The Company, through GKF, also owns and operates two single-unit Gamma Knife facilities in Lima, Peru and Guayaquil, Ecuador, which provide radiation therapy services directly to the patient, or, retail.

Rental Revenue from Medical Equipment Leasing (“Leasing”)

The Company recognizes leasing revenue under ASC 842 when services have been rendered and collectability is reasonably assured, on either a fee per use or revenue sharing basis. The terms of the contracts do not contain any guaranteed minimum payments. The Company’s lease contracts are typically for a ten-year term and are classified as either fee per use or revenue sharing. Revenue from fee per use contracts is determined by each hospital’s lease agreement with the Company. Revenues are recognized at the time the procedures are performed, based on each hospital’s contracted rate and the number of procedures performed. Under revenue sharing arrangements, the Company receives a contracted percentage of the reimbursement received by the hospital. The amount the Company expects to receive is recorded as revenue and estimated based on historical experience. Revenue estimates are reviewed periodically and adjusted as necessary. Some of the Company’s revenue sharing arrangements also have a cost sharing component and net profit share for the operating costs of the center. The Company receives payment from the hospital at an agreed upon percentage share of the hospital’s reimbursement from third party payors, and the Company is responsible for paying operating costs of the equipment determined primarily based on historical treatment protocols and cost schedules with the hospital. The Company records an estimate of operating costs which are reviewed on a regular basis and adjusted as necessary to more accurately reflect the actual operating costs and profit. The operating costs and estimated net operating profit are recorded as other direct operating costs in the consolidated statement of operations. For the years ended, December 31, 2023 and 2022, the Company recognized leasing revenue of approximately $17,772,000 and $16,655,000 under ASC 842, respectively, of which approximately $10,133,000 and $8,952,000 were for PBRT services, respectively.

Revenue sharing arrangements amounted to approximately 70% and 67% of total revenue for the years ended December 31, 2023 and 2022, respectively. Because the revenue estimates are reviewed on a quarterly basis, any adjustments required for past revenue estimates would result in an increase or reduction in revenue during the current quarterly period. Payor mix is a significant variable in the Company’s estimate for revenue sharing revenues. Fluctuations in payor mix that may result in a 5% to 10% change in the estimate could increase or decrease revenues as of December 31, 2023, by approximately $113,000 to $226,000.

Direct Patient Services Revenue(“Retail”)

The Company has stand-alone facilities in Lima, Peru and Guayaquil, Ecuador, where a contract exists between the Company’s facilities and the individual patient treated at the facility. Under ASC 606, the Company acts as the principal in this transaction and provides, at a point in time, a single performance obligation, in the form of a Gamma Knife treatment. Revenue related to a Gamma Knife treatment is recognized on a gross basis at the time when the patient receives treatment. There is no variable consideration present in the Company’s performance obligation and the transaction price is agreed upon per the stated contractual rate. GKPeru's payment terms are typically prepaid for self-pay patients and insurance provider payments are paid net 30 days. GKCE’s patient population is primarily covered by a government payor and payments are paid between three and six months, following issuance of invoice. The Company did not capitalize any incremental costs related to the fulfillment of its customer contracts. Accounts receivable under ASC 606 at December 31, 2023 was $1,626,000. Accounts receivable under ASC 606 at January 1, 2022 and December 31, 2022 was $668,000 and $1,119,000. For the years ended December 31, 2023 and 2022, the Company recognized retail revenues of approximately $3,553,000 and $3,091,000 under ASC 606, respectively.

Equipment Sales

During the year-ended December 31, 2023, the Company completed a sale of equipment to a new customer. The Company assessed this transaction under ASC 606 and concluded the Company acted as the agent in this transaction and provided, at a point in time, two performance obligations, in the form of an equipment sale of an Icon and Cobalt-60 reload. The performance obligation to sell, assign, transfer and deliver the equipment to the customer was carried out via Elekta. Revenue related to the equipment sale is recognized on a net basis when the sale is complete. The Company recognized net revenue of $200,000 on the sale of equipment for the year-ended December 31, 2023.

Salvage Value on Equipment

Salvage value is based on the estimated fair value of the equipment at the end of its useful life. The Company determines salvage value based on the estimated fair value of the equipment at the end of its useful life. There is no active resale market of Gamma Knife or PBRT equipment, but the Company believes its salvage value estimates were a reasonable assessment of the economic value of the equipment when the contract ends. There is no salvage value assigned to the two Gamma Knife units in Peru or Ecuador. The Company has not assigned salvage value to its PBRT equipment.

As of April 1, 2021, the Company reduced its estimate for salvage value for nine of its domestic Gamma Knife Perfexion units. As of October 1, 2022, the Company further reduced its estimate for salvage value for one of its domestic Gamma Knife Perfexion units. See Note 3 - Property and Equipment to the consolidated financial statements for further discussion on salvage value. As of December 31, 2023, the Company had seven domestic Gamma Knife units with salvage value ranging from $140,000 to $300,000. A further change in estimate for salvage value could have an impact on future earnings of the Company. For example, if the Company determined the salvage value of the existing seven domestic Gamma Knife units should be $0, there could be an annual increase to depreciation expense of approximately $676,000.

Accounting pronouncements issued andnotyet adopted - In November 2023, the FASB issued ASU 2023-07 Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”) which enhances the disclosure requirements for segment reporting, primarily disclosures around significant segment expenses. The key provisions of the amendments require disclosure of significant segment expense reviewed by the CODM, require disclosure of an “other” segment category, require disclosure of segment profit or loss and assets for interim periods, clarify and require disclosure of other measurements used by the CODM in assessing segment performance and allocating resources, and require disclosure of the CODM's title and position and explanation of how the CODM assesses segment performance. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating ASU 2023-07 to determine the impact it may have on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09 Income Taxes (Topic 740) Improvements to Income Tax Disclosures (“ASU 2023-09”) which requires entities, on an annual basis, to disclose: specific categories in the rate reconciliation, additional information for reconciling items that meet a quantitative threshold, the amount of income taxes paid, net of refunds, disaggregated by jurisdiction, income or loss from continuing operations before income tax, income tax expense from continuing operations disaggregated between foreign and domestic, and income tax expense from continuing operations disaggregated by federal, state and foreign. ASU 2023-09 is effective for annual periods beginning after December 31, 2024. The Company is currently evaluating ASU 2023-09 to determine the impact it may have on its consolidated financial statements.

2023 Results

For each of the years ended December 31, 2023 and 2022, 84% and 16% of the Company’s revenue was derived from the leasing segment versus the retail segment, respectively. For the year ended December 31, 2023, 51% of the Company’s revenue was derived from its Gamma Knife business, 48% was derived from its PBRT business and 1% was derived from equipment sales. For the year ended December 31, 2022, 55% of the Company’s revenue was derived from its Gamma Knife business and 45% was derived from its PBRT business.

TOTAL REVENUE

Increase

Total revenue in 2023 increased 8.0% compared to 2022 primarily due to an increase in PBRT revenues and equipment sales during the current year. Revenues from the Company’s leasing segment increased $1,117,000 in 2023 compared to 2022 due to an increase in PBRT volumes and PBRT average reimbursement, offset slightly by lower Gamma Knife revenues. Revenues from the Company’s retail segment increased by $462,000 in 2023 compared to 2022 primarily due to an increase in volume.

Gamma Knife Revenue

Increase

Revenue from Gamma Knife (in thousands) $ 10,992 1.8 % $ 10,794

Number of Gamma Knife procedures 1,195 (7.1 )% 1,286

Average revenue per procedure $ 9,198 9.6 % $ 8,393

Gamma Knife revenue for 2023 was $10,992,000 compared to $10,794,000 in 2022. Gamma Knife revenue for 2023 increased $198,000 compared to 2022 due to an increase in average reimbursement, offset by lower procedure volume.

The number of Gamma Knife procedures performed in 2023 decreased by 91 compared to 2022 primarily due to the expiration of two contracts in the second and third quarters of 2023. Excluding the two Gamma Knife contracts that expired, Gamma Knife procedures for existing sites increased 1% in 2023 compared to the prior year. The increase in Gamma Knife procedures for existing customer sites was driven by a 12% increase in the Company’s retail segment, partially offset by a 4% decrease in the Company’s Gamma Knife leasing segment in 2023 compared to 2022, respectively. The increase in Gamma Knife volumes from retail sites was due to improved marketing and physician outreach at the Company’s international locations, partially offset by downtime due to upgrade the Gamma Knife equipment in Ecuador to the Icon.

Revenue per procedure increased by $805 in 2023 compared to 2022. This increase was due to higher reimbursement at the Company’s retail sites, driven by several large reimbursements from commercial payors at a few of the customer sites.

Proton Therapy Revenue

Increase

21

Table of Contents

PBRT revenue for 2023 was $10,133,000 compared to $8,952,000 in 2022. The number of PBRT fractions performed in 2023 was 5,369 compared to 5,296 in 2022. Revenue per fraction in 2023 was $1,887 compared to $1,690 in 2022. The increase in PBRT volume was due to the higher utilization of the equipment by the customer. The average reimbursement increased due to a shift in payor mix from Medicare to commercial or other payors, which are reimbursed at a higher amount.

COSTS OF REVENUE

Increase

Percentage of total revenue 56.2 % 57.6 %

The Company’s costs of revenue, consisting of maintenance and supplies, depreciation and amortization, and other operating expenses (such as insurance, property taxes, sales taxes, marketing costs and operating costs from the Company’s revenue sharing and international sites) increased by $617,000 in 2023 compared to 2022.

Maintenance and supplies and other direct operating costs, related party, as a percentage of total revenue were 13.5% and 15.1% in 2023 and 2022, respectively. Maintenance and supplies and other direct operating costs, related party decreased by $89,000 in 2023 compared to 2022. The decrease in 2023 compared to 2022was primarily due to maintenance for one of the Company’s Gamma Knife contracts that expired in June 2023.

Depreciation and amortization costs as a percentage of total revenue were 23.8% and 23.9% in 2023 and 2022. Depreciation and amortization costs increased $347,000 in 2023 compared to 2022. The increase in 2023 compared to 2022was due to a change in estimate for useful life for one of the Company’s Gamma Knife units. As of January 1, 2023, the Company reduced its estimated useful life for one of its retail Gamma Knife units. The net effect of the change in estimate made January 1, 2023, for the year ended December 31, 2023, was a decrease in net income of approximately $207,000 or $0.03 per diluted share. This change in estimate also impacts future periods.

Other direct operating costs as a percentage of total revenue were 18.9% and 18.6% in 2023 and 2022, respectively. Other direct operating costs increased by $359,000 in 2023 compared to 2022. The increase in 2023 was primarily due to increased volume and therefore increased operating costs from the retail segment.

SELLING AND ADMINISTRATIVE EXPENSE

Increase

Selling and administrative expense $ 7,022 36.5 % $ 5,145

Percentage of total revenue 32.9 % 26.1 %

The Company’s selling and administrative costs increased $1,877,000 in 2023 compared to 2022. The increase in 2023 was due to increased staffing in the sales, finance and customer retention areas and approximately $919,000 in fees associated with new business opportunities, including the Company’s pending RI Acquisition.

INTEREST EXPENSE

Increase

Percentage of total revenue 5.2 % 4.1 %

The Company’s interest expense increased $306,000 in 2023 compared to 2022. The debt under the Credit Agreement carries a floating interest rate of LIBOR plus 3%. The increase for the year ended December 31, 2023 was due to an increase in LIBOR compared to the same period of the prior year.

(LOSS) ON WRITE DOWN OF IMPAIRED ASSETS AND ASSOCIATED REMOVAL COSTS

Increase

Loss on write down of impaired assets $ 940 * $ —

Percentage of total revenue 4.4 % 0.0 %

As of December 31, 2023 and 2022, the Company recognized a loss on the write down of impaired assets of $940,000 and $0, respectively. During the year ended December 31, 2023, the Company recorded an asset removal obligation (“ARO”) for one of the customer contracts that expired during 2023. An ARO for the second contract that expired during 2023 was recorded and impaired in a prior period. For the ARO recorded during 2023, the Company concluded the related increase to the underlying assets could not be supported by the cash flows of the equipment and therefore the Company recorded a loss on the write-down of the ARO during the three-month period ended June 30, 2023. The Company also reviewed its long-lived assets during the fourth quarter of 2023 and concluded events and circumstances existed that indicated additional impairment existed at a third Gamma Knife site related to the existing equipment. See Note 3 - Property and Equipment to the consolidated financial statements for further discussion on impairment.

INTEREST AND OTHER INCOME

Increase

Interest and other income (loss) $ 422 385.1 % $ 87

Percentage of total revenue 2.0 % 0.4 %

Interest and other income increased $422,000 in 2023 compared to 2022. The increases are primarily due to increases in the interest paid on the Company’s cash in 2023 compared to 2022.

INCOME TAX EXPENSE

Increase

Percentage of total revenue 2.0 % 4.9 %

Income tax expense decreased $532,000 in 2023 compared to 2022. The decrease in income tax expense in 2023 was due to lower earnings during 2023, and return-to-provision adjustments arising from foreign tax returns filed during 2022, as well as permanent domestic tax differences recorded in the prior year.

The Company anticipates that it will continue to record income tax expense if it operates profitably in the future. Currently there are state income tax payments required for most states in which the Company operates. At December 31, 2022, the Company exhausted the remainder of its net operating loss carryforward for federal income tax return purposes. The Company has net operating loss carryforwards for state income tax purposes.

Table of Contents

NET (LOSS) INCOME ATTRIBUTABLE TO NON-CONTROLLING INTERESTS

Increase

Percentage of total revenue (1.6 )% 1.1 %

Net income attributable to non-controlling interests decreased $572,000 in 2023 compared to 2022. Net income attributable to non-controlling interests represents the pre-tax income earned by the 19% non-controlling interest in GKF, and the pre-tax income or losses of the non-controlling interests in various subsidiaries controlled by GKF. The decrease or increase in net income attributable to non-controlling interests reflects the relative profitability of GKF. The decrease in 2023 compared to 2022 was due to lower pre-tax income for GKF stand-alone operations.

NET INCOME ATTRIBUTABLE TO AMERICAN SHARED HOSPITAL SERVICES

(In thousands, Increase

except per share amounts) 2023 (Decrease) 2022

Net income attributable to ASHS $ 610 (54.1 )% $ 1,328

Net income per share attributable to ASHS, diluted $ 0.10 (52.4 )% $ 0.21

Net income attributable to American Shared Hospital Services decreased $718,000 in 2023 compared to 2022. Net income for the Company’s retail segment decreased $49,000 in 2023 compared to 2022. The decrease in 2023 compared to 2022 was primarily due to down time for the upgrade of the equipment in Ecuador. Net income for the Company’s leasing segment decreased $669,000 in 2023 compared to 2022. The decrease in 2023 compared to 2022 was due to higher selling and administrative expense to support the Company’s pursuit of new business opportunities as well as higher interest expense, losses on the write-down of impaired equipment and associated removal costs, and the Company’s change in estimate for depreciation.

LIQUIDITY AND CAPITAL RESOURCES

The Company’s primary liquidity needs are to fund capital expenditures as well as support working capital requirements. In general, the Company’s principal sources of liquidity are cash and cash equivalents on hand and a $7,000,000 revolving line of credit. As of December 31, 2023, the Company borrowed $2,500,000 on its line of credit, which was paid off in January 2024. The Company had cash and cash equivalents, including restricted cash, of $13,808,000 at December 31, 2023 compared to $12,453,000 at December 31, 2022, an increase of $1,355,000. The Company’s expected primary cash needs on both a short and long-term basis are for capital expenditures, business expansion (including the payment of the purchase price in connection with the RI acquisition), working capital, and other general corporate purposes. The Company believes that its borrowing capacity under its Revolving Line and its access to capital resources are sufficient to continue funding its present operations, to meet its commitments on its existing debt, and to meet its operating capital and funding requirements for the next 12 months from the date of this Annual Report.

Cash Flows

Cash Flows Provided by Operating Activities

Operating activities provided $5,718,000 of cash in 2023, which was driven by net income of $265,000, non-cash charges for depreciation and amortization of $5,165,000, a loss on the write down of impaired assets of $940,000, stock-based compensation expense of $389,000, accretion of deferred issuance costs of $46,000, income taxes payable of $974,000, and changes in prepaids and other assets of $21,000. These increases were offset by net changes in Right-of-Use assets and lease liabilities of $34,000, deferred income taxes of $759,000, changes in payables and other accrued liabilities of $79,000, changes in receivables of $719,000, and changes in related party liabilities of $491,000.

The Company’s trade accounts receivable increased by $542,000 to $4,343,000 at December 31, 2023 from $3,801,000 at December 31, 2022. The number of days revenue (sales) outstanding (“DSO”) in accounts receivable as of December 31, 2023 was 74 days compared to 70 days at December 31, 2022. DSO fluctuates depending on timing of customer payments received and the mix of fee per use versus revenue sharing and retail customers. The revenue sharing and retail sites generally have longer collection periods than fee per use sites.

Cash Flows Used in Investing Activities

Investing activities used $6,273,000 of cash in 2023, due to payments made towards the purchase of property and equipment. During 2023, the Company completed one Esprit upgrade and began a second Esprit upgrade at existing customer sites, and predominantly completed the installation of a LINAC at it’s new site in Puebla, Mexico. The Company amended its Credit Agreement to include financing for the LINAC equipment in in January 2024.

Cash Flows Provided by (Used in) Financing Activities

Financing activities provided $1,910,000 of cash during 2023, which was driven by long-term debt financing from the second tranche of the DFC Loan of $1,750,000 and net borrowings on the Revolving Line of $2,500,000. These increases were offset by payments on long-term debt of $2,129,000, debt issuance costs of $9,000 and payments on short-term financing of insurance premiums of $202,000.

Working Capital

The Company had working capital at December 31, 2023 of $9,677,000 compared to working capital of $13,548,000 at December 31, 2022. The $3,871,000 decrease in net working capital was primarily due to a decrease in cash driven by payments for equipment that the Company financed subsequent to year-end. The Company paid substantially all of the project invoices for the Puebla equipment during 2023. On January 25, 2024, the Company amended the Credit Agreement to include financing for the LINAC equipment in Puebla totaling $2,700,000. See Note 5 - Long-Term Debt to the consolidated financial statements for more information.

Table of Contents

The Company, in the past, has secured financing for its Gamma Knife and radiation therapy units. The Company has secured financing for its projects from several lenders and anticipates that it will be able to secure financing on future projects from these or other lending sources, but there can be no assurance that financing will continue to be available on acceptable terms.

Long-Term Debt

On April 9, 2021, the Company and certain of its domestic subsidiaries entered into a five year $22,000,000 credit agreement with Fifth Third Bank, N.A., which refinanced its existing domestic Gamma Knife portfolio. The lease financing previously obtained by Orlando was also refinanced as long-term debt by the Credit Agreement. The Credit Agreement includes three loan facilities: (1) a $9,500,000 term loan (the “Term Loan”), which was used to refinance the domestic Gamma Knife debt and finance leases and the associated closing costs; (2) a $5,500,000 delayed draw term loan (the “DDTL”), which was used to refinance the Company’s PBRT finance leases and associated closing costs and to provide additional working capital for the Company; and (3) a $7,000,000 revolving line of credit (the “Revolving Line”), which is available for the Company’s future projects and general corporate purposes. The Company borrowed $2,500,000 under the Revolving Line as of December 31, 2023, which the Company repaid in January 2024. The Credit Agreement is 48% amortized over a 58-month period with a balloon payment upon maturity and is secured by a lien on substantially all of the assets of the Company and certain of its domestic subsidiaries. The Revolving Loan, the Term Loan, and the DDTL will mature on April 9, 2026 unless accelerated due to the occurrence of certain events specified in the Credit Agreement. The Revolving Line is charged an unused line fee of 0.25% per annum. The Term Loan and DDTL have interest and principal payments due quarterly. Principal amortization on an annual basis for the Term Loan and DDTL equates to 48% of the original principal loan commitments in years one through five and an end of term payment of the remaining principal balance.

On January 25, 2024, the, the Company entered into a First Amendment to Credit Agreement with Fifth Third which amended the Credit Agreement to add the Supplemental Term Loan, a new term loan in the aggregate principal amount of $2,700,000. The proceeds of the Supplemental Term Loan were advanced in a single borrowing on January 25, 2024, and were used to finance capital expenditures that the Company paid cash for during 2023 for its operations in Puebla, Mexico and other related transaction costs. The Supplemental Term Loan will mature on January 25, 2030, unless accelerated due to the occurrence of certain events specified in the Credit Agreement. Interest on the Supplemental Term Loan is payable monthly during the initial twelve month period following the First Amendment Effective Date. Following such twelve month period, the Company is required to make equal monthly payments of principal and interest to fully amortize the amount outstanding under the Supplemental Term Loan by the Maturity Date. The Supplemental Term Loan is secured by a lien on substantially all of the assets of the Company and certain of its domestic subsidiaries. The First Amendment also replaces the LIBOR-based rates in the Credit Agreement with SOFR-based rates. Pursuant to the First Amendment, advances under the Credit Agreement bear interest at a floating rate per annum equal to SOFR plus 3.00%, subject to a SOFR floor of 0.00%.

As of December 31, 2023, the Company was subject to customary covenants under the Credit Agreement which included, among other covenants and obligations, a minimum fixed charge coverage ratio of 1.25 to 1.0 and a total funded debt to EBITDA ratio of 3.0 to 1.0 (tested on a trailing twelve-month basis at the end of each fiscal quarter), along with an annual clean-up covenant that requires the Company to cause the outstanding principal balance under the Revolving Loan to be less than $3,500,000 for at least 30 consecutive days during each calendar year (the “Credit Agreement Covenants”). The Company was in compliance with the Credit Agreement Covenants as of December 31, 2023.

The Company’s acquisition of GKCE and the Gamma Knife Esprit in Ecuador is financed with DFC. The loan entered into with DFC in June 2020 was obtained through the Company's wholly-owned subsidiary, HoldCo, and is guaranteed by GKF. The DFC Loan is secured by a lien on GKCE’s assets. The first tranche of the DFC Loan was funded in June 2020. In October 2023, the second tranche of the DFC Loan was funded in the amount of $1,750,000 to finance its equipment upgrade in Ecuador. The amount outstanding under the first tranche of the DFC Loan is payable in 29 quarterly installments with a fixed interest rate of 3.67%. The amount outstanding under the second tranche of the DFC Loan is payable in 16 quarterly installments with a fixed interest rate of 7.49%. The Company’s loan with DFC also contains customary covenants and representations, which, following the funding of the second Tranche, the Company was not in compliance with as of December 31, 2023. The Company obtained a waiver for the covenants for December 31, 2023.

The DFC Loan contains customary covenants among other covenants and obligations, requirements that the Company maintain certain financial ratios related to liquidity and cash flow as well as depository requirements. On March 28, 2024 the Company received a waiver and amendment from DFC for certain covenants as of December 31, 2023 and through December 31, 2024 and amended other covenants and definitions permanently. The Company expects to be in compliance with all debt covenants pursuant to the DFC Loan as amended and waived at March 31, 2024.

If the Company fails to comply with the Credit Agreement Covenants or the DFC Loan Covenants, the Company’s credit commitments could be terminated and the principal of any outstanding borrowings, together with any accrued but unpaid interest, under the Credit Agreement or the DFC Loan could be declared immediately due and payable. Furthermore, The lenders under the Credit Agreement and the DFC Loan could also exercise their rights to take possession of, and to dispose of, the collateral securing the credit facilities and loans and could take any additional remedies upon default as set forth in each such agreement.

The Company’s combined long-term debt, net, totaled $13,125,000 as of December 31, 2023. See Note 5 - Long Term Debt to the consolidated financial statements for additional information.

Commitments

As of December 31, 2023, the Company had commitments to purchase and install Gamma Knife and LINAC equipment totaling $15,925,000. There are no significant cash requirements, pending financing, for these commitments in the next 12 months. There can be no assurance that financing will be available for the Company’s current or future projects, or at terms that are acceptable to the Company. However, the Company currently has cash on hand of $13,808,000 and a line of credit of $7,000,000 to fund these projects.

The Company also had commitments to service these various equipment commitments totaling $14,805,000. The Gamma Knife and certain other service contracts are paid monthly, as service is performed. The Company believes that cash flow from operations, cash on hand and its line of credit will be sufficient to cover these payments. See Note 10 - Commitments and Contingencies to the consolidated financial statements for further discussion on commitments.

The Company’s commitments to purchase a second and third PBRT unit expired in January 2024.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of

American Shared Hospital Services, Inc.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of American Shared Hospital Services, Inc. (the “Company”) as of December 31, 2023 and 2022, and the related consolidated statements of operations, shareholders’ equity and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the consolidated financial position of the Company as of December 31, 2023 and 2022, and the consolidated results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which they relate.

Rental Revenue from Medical Equipment Leasing – Estimates of Reimbursement Rates

As described in Note 2 in the Company’s consolidated financial statements, the Company has rental revenue from medical equipment leasing on either a fee per use or revenue sharing basis that are recognized under Accounting Standards Codification 842, Leases. Under revenue sharing arrangements, the Company receives a contracted percentage of the reimbursement received by the hospital. Under fee per use arrangements, the Company receives payment from the hospital as determined by each hospital’s lease agreement with the Company.

We identified management’s estimates of reimbursement rates to record rental revenue from medical equipment leasing and related accounts receivable, as a critical audit matter. Rental revenue from medical equipment leasing and related accounts receivable involves significant judgment and estimation, including measurement uncertainty, by management based on the estimates and assumptions used and are subject to adjustments based on actual reimbursements received by the Company. In turn, auditing management’s judgments and estimates related to rental revenue from medical equipment leasing and related accounts receivable involved a high degree of subjectivity, as they are based on estimates of reimbursement rates.

The primary procedures we performed to address this critical audit matter included:

We have served as the Company’s auditor since 2000.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1– BUSINESS AND BASIS OF PRESENTATION

Business – These consolidated financial statements include the accounts of American Shared Hospital Services (“ASHS”) and its subsidiaries (the “Company”) as follows: ASHS wholly-owns the subsidiaries American Shared Radiosurgery Services (“ASRS”), PBRT Orlando, LLC (“Orlando”), ASHS-Mexico, S.A. de C.V. (“ASHS-Mexico”), ASHS-Rhode Island Proton Beam Radiation Therapy, LLC, ASHS-Bristol Radiation Therapy, LLC, OR21, Inc., and MedLeader.com, Inc. (“MedLeader”); ASHS is the majority owner of Long Beach Equipment, LLC (“LBE”); ASRS is the majority-owner of GK Financing, LLC (“GKF”) which wholly-owns the subsidiary Instituto de Gamma Knife del Pacifico S.A.C. (“GKPeru”) and HoldCo GKC S.A. (“HoldCo”). HoldCo wholly owns the subsidiary Gamma Knife Center Ecuador S.A. (“GKCE”). GKF is the majority owner of the subsidiaries Albuquerque GK Equipment, LLC (“AGKE”) and Jacksonville GK Equipment, LLC (“JGKE”).

The Company (through ASRS) and Elekta AG (“Elekta”), the manufacturer of the Gamma Knife (through its wholly-owned United States subsidiary, GKV Investments, Inc.), entered into an operating agreement and formed GKF. During 2023, GKF leased Gamma Knife units to twelve medical centers in the United States in the states of California, Florida, Illinois, Indiana, Mississippi, Nebraska, New Mexico, New York, Ohio, Oregon, and Texas. GKF also owns and operates two single-unit Gamma Knife facilities in Lima, Peru and Guayaquil, Ecuador. The Company through its wholly-owned subsidiary, Orlando, provided proton beam radiation therapy (“PBRT”) and related equipment to a customer in the United States.

The Company formed the subsidiary GKPeru and acquired GKCE for the purposes of expanding its business internationally; Orlando and LBE to provide PBRT equipment and services in Orlando, Florida and Long Beach, California, respectively; and AGKE and JGKE to provide Gamma Knife equipment and services in Albuquerque, New Mexico and Jacksonville, Florida, respectively. AGKE began operations in the second quarter of 2011 and JGKE began operations in the fourth quarter of 2011. Orlando treated its first patient in April 2016. GKPeru treated its first patient in July 2017. LBE is not expected to generate revenue within the next two years.

On April 27, 2022, the Company signed a Joint Venture Agreement (the “Agreement”) with the principal owners of Radioterapia Guadalupe Amor y Bien S.A. de C.V. (“Guadalupe”) to establish AB Radiocirugia y Radioterapia de Puebla, S.A.P.I. de C.V. of Puebla (“Puebla”) to treat public- and private-paying cancer patients and provide radiation therapy and radiosurgery services locally in Mexico. The Company and Guadalupe hold 85% and 15% ownership interests, respectively, in Puebla. Under the Agreement, the Company is responsible for providing a linear accelerator and Guadalupe will be accountable for all site modification costs. The Company formed ASHS-Mexico on October 3, 2022 to establish Puebla. Puebla was formed on December 15, 2022 and the Company expects Puebla to begin treating patients in June 2024. Operating costs incurred during the year ended December 31, 2023 by Puebla, are included in the consolidated statement of operations.

The Company continues to develop its design and business model for The Operating Room for the 21st CenturySM through its 50% owned OR21, LLC (“OR21”). The remaining 50% of OR21 is owned by an architectural design company. OR21 is not expected to generate significant revenue within the next two years.

MedLeader was formed to provide continuing medical education online and through videos for doctors, nurses, and other healthcare workers. This subsidiary is not operational at this time.

On November 10, 2023, the Company entered into an Investment Purchase Agreement (the “IPA”) with GenesisCare USA, Inc. (the “GenesisCare”) and GenesisCare USA Holdings, Inc. (“GC Holdings”), pursuant to which GenesisCare agreed to sell to the Company its entire equity interest in each of Southern New England Regional Cancer Center, LLC and Roger Williams Radiation Therapy, LLC, (collectively, the “RI Target Companies”) together with the assignment of certain payor contacts for a purchase price of $2,850,000 (such transaction, the “RI Acquisition”). The equity interests to be acquired by the Company under the IPA equates to a 60% interest in each RI Target Company. The RI Target Companies operate three functional radiation therapy cancer centers in Rhode Island. The RI Acquisition is contingent upon certain closing conditions, including GenesisCare and the Company entering into a consent agreement with the Rhode Island Department of Health and approval of all equity holders and managers of each RI Target Company. On March 1, 2024, the Company, GenesisCare and GC Holding entered into a First Amendment to the Investment Agreement pursuant to which the parties agreed to extend the date on which a party could terminate the IPA if the closing conditions had not been met from March 10, 2024 to April 30, 2024. The Company anticipates that these conditions will be met in April 2024.

The transaction will be accounted for as a business combination under ASC 805 Business Combinations, which requires, among other things, that purchase consideration, assets acquired, and liabilities assumed be measured at their fair values as of the acquisition date. The initial purchase allocation for the business combination is incomplete at this time, subject to finalizing the IPA. After closing, disclosures regarding amounts recognized for major classes of assets acquired and liabilities assumed will be provided once the initial accounting is completed.

Costs related to legal, financial and due diligence services performed in connection with this transaction recorded in the consolidated statement of operations were $432,000 for the year ended December 31, 2023.

All intercompany accounts and transactions have been eliminated in consolidation.

NOTE 2– ACCOUNTING POLICIES

Use of estimates in the preparation of financial statements – In preparing the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America, management makes estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the consolidated financial statements, as well as the reported amounts of revenues and expenses during the reporting period. Significant accounting estimates reflected in the Company’s consolidated financial statements include the estimated useful lives of property and equipment and its salvage values, revenues and costs of sales for revenue sharing customers. Actual results could differ from those estimates.

Advertising and marketing – The Company expenses advertising and marketing costs as incurred (collectively, “marketing costs”). Marketing costs were $165,000 and $233,000 during the years ended December 31, 2023 and 2022, respectively. Marketing costs include joint marketing with customers and corporate advertising costs. Marketing costs are recorded in other direct operating costs and sales and administrative costs in the consolidated statements of income.

Sales and Service – The Company markets its financial and turn-key solutions directly to cancer treatment centers, hospitals, and large cancer networks worldwide through its sales staff. Sales expense includes payroll and travel costs for the Company’s sales staff. The Company also typically provides the equipment, as well as planning, installation, reimbursement and marketing support services to its customers.

Cash and cash equivalents – The Company considers all liquid investments with original maturities of three months or less at the date of purchase to be cash equivalents. Restricted cash is not considered a cash equivalent for purposes of the consolidated statements of cash flows.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Restricted cash – Restricted cash represents the minimum cash that must be maintained in GKF to fund operations, per the subsidiary’s operating agreement and the minimum cash that must be maintained by GKF per it’s financing agreement with the United States International Development Finance Corporation (“DFC”). See further discussion at Note 5 - Long Term Debt.

Business and credit risk – The Company maintains its cash balances, which exceed federally insured limits, in financial institutions. The Company believes it is not exposed to any significant credit risk on cash and cash equivalents. The Company monitors the financial condition of the financial institutions it uses on a regular basis.

All of the Company’s revenue was provided by 15 locations or 1 PBRT unit and 14 Gamma Knife units in each of 2023 and 2022. One location accounted for approximately 48% and 45% of the Company’s total revenue in 2023 and 2022, respectively. At December 31, 2023, two locations each individually accounted for 30% and 31% of total accounts receivable, respectively. At December 31, 2022, four locations each individually accounted for 12%, 14%, 16% and 22% of total accounts receivable, respectively. The Company performs credit evaluations of its customers and generally does not require collateral. The Company has not experienced significant losses related to receivables from individual customers or groups of customers in any particular geographic area.

All of the Company’s radiosurgery devices have been purchased through Elekta, to date. However, there are other manufacturers that also make radiosurgery devices.

Accounts receivable and allowance for credit losses – Accounts receivable are recorded at net realizable value. An allowance for doubtful accounts is estimated based on historical collections plus an allowance for expected losses. Receivables are considered past due based on contractual terms and are charged off in the period that they are deemed uncollectible. Recoveries of receivables previously charged off are offset against bad debt expense when received.

Non-controlling interests - The Company reports its non-controlling interests as a separate component of shareholders’ equity. Non-controlling interest is determined by the income (loss) multiplied by the non-controlling interest in subsidiaries, and the income or losses of the non-controlling interests in various subsidiaries controlled by GKF. The Company also presents the consolidated net income and the portion of the consolidated net income (loss) allocable to the non-controlling interests and to the shareholders of the Company separately in its consolidated statements of operations.

Property and equipment – Property and equipment are stated at cost less accumulated depreciation. Depreciation for Gamma Knife and other equipment is determined using the straight-line method over the estimated useful lives of the assets, which for medical and office equipment is generally 3 – 10 years, and after accounting for salvage value on the equipment where applicable. The Company acquired a building as part of the acquisition of GKCE in June 2020. Depreciation for buildings is determined using the straight-line method over 20 years. The Company determines salvage value based on the estimated fair value of the equipment at the end of its useful life. As of October 1, 2022, the Company reduced its estimate for salvage value for one of its domestic Gamma Knife Perfexion units. As of December 31, 2023 and 2022, the Company had seven domestic Gamma Knife units with salvage value ranging from $140,000 to $300,000.

As of January 1, 2023, the Company reduced its estimated useful life for one of its direct patient services Gamma Knife units. The net effect of the change in estimate made January 1, 2023, for the year ended December 31, 2023, was a decrease in net income of approximately $207,000 or $0.03 per diluted share. This change in estimate also impacts future periods.

Depreciation for PBRT and related equipment is determined using the modified units of production method, which is a function of both time and usage of the equipment. This depreciation method allocates costs considering the projected volume of usage through the useful life of the PBRT unit, which has been estimated at 20 years. The estimated useful life of the PBRT unit is consistent with the estimated economic life of 20 years.

The Company leases Gamma Knife and radiation therapy equipment to its customers under arrangements accounted for as operating leases. At December 31, 2023, the Company held equipment under operating lease contracts with customers with an original cost of $70,635,000 and accumulated depreciation of $52,302,000. At December 31, 2022, the Company held equipment under operating lease contracts with customers with an original cost of $69,306,000 and accumulated depreciation of $47,992,000.

As of December 31, 2023 and 2022, the Company recognized a loss on the write down of impaired assets of $940,000 and $0, respectively. During the year ended December 31, 2023, the Company recorded an asset removal obligation (“ARO”) for one of the customer contracts that expired during 2023. An ARO for the second contract that expired during 2023 was recorded and impaired in a prior period. For the ARO recorded during 2023, the Company concluded the related increase to the underlying assets could not be supported by the cash flows of the equipment and therefore the Company recorded a loss on the write-down of the ARO in June 2023. The Company’s estimate for the ARO liability was subsequently adjusted during the fourth quarter of 2023 based on new information. Total ARO impairment for the year ended December 31, 2023 was $290,000. The Company also reviewed its long-lived assets during the fourth quarter of 2023 and concluded events and circumstances existed that indicated additional impairment existed at a third Gamma Knife site related to the existing equipment. Total equipment impairment for the year ended December 31, 2023 was $650,000. See further discussion under Note 2 - Long-lived asset impairment and Note 3 - Property and Equipment.

NOTE 2– ACCOUNTING POLICIES (CONTINUED)

Revenue recognition - The Company recognizes revenues under ASC 842Leases (“ASC 842”) and ASC 606Revenue from Contracts with Customers (“ASC 606”).

Rental income from medical equipment leasing (“leasing”) – The Company recognizes leasing revenue under ASC 842 when services have been rendered and collectability is reasonably assured, on either a fee per use or revenue sharing basis. The terms of the contracts do not contain any guaranteed minimum payments. The Company’s lease contracts are typically for a ten-year term and are classified as either fee per use or revenue sharing. Revenue from fee per use contracts is determined by each hospital’s lease agreement with the Company. Revenues are recognized at the time the procedures are performed, based on each hospital’s contracted rate and the number of procedures performed. Under revenue sharing arrangements, the Company receives a contracted percentage of the reimbursement received by the hospital. The amount the Company expects to receive is recorded as revenue and estimated based on historical experience. Revenue estimates are reviewed periodically and adjusted as necessary. Some of the Company’s revenue sharing arrangements also have a cost sharing component and net profit share for the operating costs of the center. The Company receives payment from the hospital at an agreed upon percentage share of the hospital’s reimbursement from third party payors, and the Company is responsible for paying operating costs of the equipment determined primarily based on historical treatment protocols and cost schedules with the hospital. The Company records an estimate of operating costs which are reviewed on a regular basis and adjusted as necessary to more accurately reflect the actual operating costs and profit. The operating costs and estimated net operating profit are recorded as other direct operating costs in the consolidated statement of operations. For the years ended, December 31, 2023 and 2022, the Company recognized leasing revenue of approximately $17,772,000 and $16,655,000 under ASC 842, respectively, of which approximately $10,133,000 and $8,952,000 were for PBRT services, respectively.

Revenue sharing arrangements amounted to approximately

70% and

67% of total revenue for the years ended

December 31, 2023 and 2022, respectively. Because the revenue estimates are reviewed on a quarterly basis, any adjustments required for past revenue estimates would result in an increase or reduction in revenue during the current quarterly period. Payor mix is a significant variable in the Company’s estimate for revenue sharing revenues.

Direct patient services income (“retail”) – The Company has stand-alone facilities in Lima, Peru and Guayaquil, Ecuador, where a contract exists between the Company’s facilities and the individual patient treated at the facility. Under ASC 606, the Company acts as the principal in this transaction and provides, at a point in time, a single performance obligation, in the form of a Gamma Knife treatment. Revenue related to a Gamma Knife treatment is recognized on a gross basis at the time when the patient receives treatment. There is no variable consideration present in the Company’s performance obligation and the transaction price is agreed upon per the stated contractual rate. GKPeru's payment terms are typically prepaid for self-pay patients and insurance provider payments are paid net 30 days. GKCE’s patient population is primarily covered by a government payor and payments are paid between three and six months, following issuance of invoice. The Company did not capitalize any incremental costs related to the fulfillment of its customer contracts. Accounts receivable under ASC 606 at December 31, 2023 was $1,626,000. Accounts receivable under ASC 606 at January 1, 2022 and December 31, 2022 was $668,000 and $1,119,000. For the years ended December 31, 2023 and 2022, the Company recognized retail revenues of approximately $3,553,000 and $3,091,000 under ASC 606, respectively.

Equipment sales – During the year-ended December 31, 2023, the Company completed a sale of equipment to a new customer. The Company assessed this transaction under ASC 606 and concluded the Company acted as the agent in this transaction and provided, at a point in time, two performance obligations, in the form of an equipment sale of an Icon and Cobalt-60 reload. The performance obligation to sell, assign, transfer and deliver the equipment to the customer was carried out via Elekta. Revenue related to the equipment sale is recognized on a net basis when the sale is complete. The Company recognized net revenue of $200,000 on the sale of equipment for the year-ended December 31, 2023.

Stock-based compensation – The Company measures all stock-based compensation awards at fair value and records such expense in its consolidated financial statements over the requisite service period of the related award. See Note 8 - Stock-Based Compensation Expense for additional information on the Company’s stock-based compensation programs.

Costs of revenue – The Company’s costs of revenue consist primarily of maintenance and supplies, depreciation and amortization, and other operating expenses (such as insurance, property taxes, sales taxes, marketing costs and operating costs from the Company’s revenue sharing and retail sites). Costs of revenue are recognized as incurred.

Income taxes – The Company accounts for income taxes using the asset and liability method. Under this method, deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

NOTE 2– ACCOUNTING POLICIES (CONTINUED)

The Company accounts for uncertainty in income taxes as required by the provisions of ASC 740Income taxes (“ASC 740”), which clarifies the accounting for uncertainty in income taxes recognized in an enterprise’s financial statements. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained on audit, including resolution of related appeals or litigation processes, if any. The second step is to estimate and measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. It is inherently difficult and subjective to estimate such amounts, as this requires the Company to determine the probability of various possible outcomes. The Company considers many factors when evaluating and estimating the Company’s tax positions and tax benefits, which may require periodic adjustments and may not accurately anticipate actual outcomes.

See Note 7 - Income Taxes for further discussion on income taxes.

Functional currency – Based on guidance provided in accordance with ASC 830,Foreign Currency Matters (“ASC 830”), the Company analyzes its operations outside the United States to determine the functional currency of each operation. Management has determined that these operations are accounted for in U.S. dollars since the primary transactions incurred are in U.S. dollars and the Company provides significant funding towards the startup of the operation. When Management determines that an operation has become predominantly self-sufficient, the Company will reassess its accounting for the operation to the local currency from the U.S. dollar. The Company analyzed it’s Gamma Knife site in Peru and its startup operations in Mexico for Puebla under ASC 830 as of December 31, 2023 and 2022 and concluded the functional currency was the U.S. dollar. As facts and circumstances change, the Company will revisit this conclusion. The functional currency of the Company’s Gamma Knife site in Ecuador is the U.S. dollar because that is the local currency of Ecuador.

Asset Retirement Obligations – Based on the guidance provided in ASC 410,Asset Retirement Obligations (“ASC 410”), the Company analyzed its existing lease agreements and determined whether an ARO exists to remove the respective units at the end of the lease terms. As of December 31, 2023, the Company has two AROs recorded for the two customer sites that expired during the year, totaling $650,000. One ARO was recorded and impaired in a prior period. The Company recorded and impaired an ARO for the second customer site during 2023.No liability has been recorded as of December 31, 2023 for the remaining Gamma Knife or PBRT locations, because it is uncertain these units will be removed and the Company historically has not removed the equipment at the end of the lease term. The Company will re-evaluate the need to record additional ARO liabilities on a periodic basis when facts and circumstances change that could affect this conclusion.

Earnings per share – The Company calculates diluted shares using the treasury stock method. Basic earnings per share excludes dilution and is computed by dividing income available to common shareholders by the weighted average number of common shares outstanding for the year. The fully vested restricted stock units not issued and outstanding and unvested restricted stock units, are also included therein. Diluted earnings per share reflect the potential dilution that could occur if common shares were issued pursuant to the exercise of options and from unvested restricted stock units. The computation for the years ended December 31, 2023 and 2022 excluded approximately 144,000 and 20,000, respectively, of the Company’s stock options because the exercise price of the options was higher than the average market price during the period. The weighted average common shares outstanding for the years ended December 31, 2023 and 2022, included approximately 123,000 and 123,000, respectively, of the Company's restricted stock awards that are fully vested but are deferred for issuance.

The following table illustrates the computations of basic and diluted earnings per share for the years ended December 31, 2023 and 2022.

Business segment information - Based on the guidance provided in accordance with ASC 280Segment Reporting (“ASC 280”), the Company analyzed its subsidiaries which are all in the business of providing radiosurgery and radiation therapy services, either through leasing to healthcare providers or directly to patients, and concluded there are two reportable segments, leasing and retail. During 2023, the Company provided Gamma Knife and PBRT equipment to thirteen hospitals in the United States and owns and operates two single-unit facilities in Lima, Peru and Guayaquil, Ecuador as of December 31, 2023. An operating segment is defined by ASC 280 as it engages in business activities in which it may recognize revenues and incur expenses, its operating results are regularly reviewed by the Company’s Chief Operating Decision Maker (“CODM”), and its discrete financial information is available. The Company determined two reportable segments existed due to similarities in economics of business operations and how the Company recognizes revenue for the patient treatment. The operating results of the two reportable segments are reviewed by the Company’s Executive Chairman of the Board, who is also the CODM.

For the years ended December 31, 2023 and 2022, the Company’s PBRT operations represented a significant majority of the net income attributable to American Shared Hospital Services from the leasing segment, disclosed below. The revenues, depreciation, interest expense, interest income, tax expense, and net income attributable to American Shared Hospital Services, and total asset allocations for the Company’s two reportable segments as of December 31, 2023 and 2022 consists of the following:

NOTE 2– ACCOUNTING POLICIES (CONTINUED)

Long lived asset impairment – The Company assesses the recoverability of its long-lived assets when events or changes in circumstances indicate their carrying value may not be recoverable. Such events or changes in circumstances may include: a significant adverse change in the extent or manner in which a long-lived asset is being used, significant adverse change in legal factors or in the business climate that could affect the value of a long-lived asset, an accumulation of costs significantly in excess of the amount originally expected for the acquisition or development of a long-lived asset, current or future operating or cash flow losses that demonstrate continuing losses associated with the use of a long-lived asset, or a current expectation that, more likely than not, a long-lived asset will be sold or otherwise disposed of significantly before the end of its previously estimated useful life. The Company performs impairment testing at the asset group level that represents the lowest level for which identifiable cash flows are largely independent of the cash flows of other assets and liabilities. The Company assesses recoverability of a long-lived asset by determining whether the carrying value of the asset group can be recovered through projected undiscounted cash flows over their remaining lives. If the carrying value of the asset group exceeds the forecasted undiscounted cash flows, an impairment loss is recognized, measured as the amount by which the carrying amount exceeds estimated fair value. An impairment loss is charged to the consolidated statement of operations in the period in which management determines such impairment. As of December 31, 2023, impairment of $650,000 was recorded related to cash flow losses of one of the Company’s Gamma Knife units. No impairment was recorded as of December 31, 2022. See Note 3 - Property and Equipment for further discussion.

Goodwill and intangible assets - The Company recorded goodwill of $1,265,000 and an intangible asset with a fair value of $78,000 as part of the acquisition of GKCE in June 2020. The intangible asset identified was GKCE’s trade name and the Company assigned an indefinite useful life to the asset. Based on the guidance provided in accordance with ASC 350Intangibles-Goodwill and Other (“ASC 350”), the Company does not amortize the intangible asset because it has an indefinite life. The Company assesses goodwill at the reporting unit level, which has been determined to be GKCE. Each reporting period, the Company assesses whether events or circumstances continue to support an indefinite useful life for the intangible asset. Per ASC 350, the Company tests goodwill and intangibles for impairment annually or as events or circumstances change that indicate the fair value may be below the carrying amount. As of December 31, 2023 and 2022, there has been no change to the Company's assessment of the value of intangible assets or goodwill.

Accounting pronouncements issued andnotyet adopted - In November 2023, the FASB issued ASU 2023-07Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures (“ASU 2023-07”) which enhances the disclosure requirements for segment reporting, primarily disclosures around significant segment expenses. The key provisions of the amendments require disclosure of significant segment expense reviewed by the CODM, require disclosure of an “other” segment category, require disclosure of segment profit or loss and assets for interim periods, clarify and require disclosure of other measurements used by the CODM in assessing segment performance and allocating resources, and require disclosure of the CODM's title and position and explanation of how the CODM assesses segment performance. ASU 2023-07 is effective for annual periods beginning after December 15, 2023 and interim periods within fiscal years beginning after December 15, 2024. The Company is currently evaluating ASU 2023-07 to determine the impact it may have on its consolidated financial statements.

In December 2023, the FASB issued ASU 2023-09Income Taxes (Topic 740) Improvements to Income Tax Disclosures (“ASU 2023-09”) which requires entities, on an annual basis, to disclose: specific categories in the rate reconciliation, additional information for reconciling items that meet a quantitative threshold, the amount of income taxes paid, net of refunds, disaggregated by jurisdiction, income or loss from continuing operations before income tax, income tax expense from continuing operations disaggregated between foreign and domestic, and income tax expense from continuing operations disaggregated by federal, state and foreign. ASU 2023-09 is effective for annual periods beginning after December 31, 2024. The Company is currently evaluating ASU 2023-09 to determine the impact it may have on its consolidated financial statements.

Reclassifications - Certain comparative balances as of and for the year ended have been reclassified to make them consistent with the current year presentation.

NOTE 3– PROPERTY AND EQUIPMENT

Property and equipment consists of the following:

As of December 31, 2023 and 2022, approximately $3,966,000 and $2,201,000, respectively, of the net property and equipment balance is outside of the United States. Depreciation expense recorded in costs of revenue and selling and administrative expense in the consolidated statements of income for the years ended December 31, 2023 and 2022, was $5,165,000 and $4,783,000, respectively.

As of October 1, 2022, the Company reduced its estimate for salvage value for one of its domestic Gamma Knife Perfexion units. As of January 1, 2023, the Company reduced its estimated useful life for one of its direct patient services Gamma Knife units. The net effect of the change in estimate made January 1, 2023, for the year ended December 31, 2023, was a decrease in net income of approximately $207,000 or $0.03 per diluted share. This change in estimate also impacts future periods.

As of December 31, 2023 and 2022, the Company recognized a loss on the write down of impaired assets of $940,000 and $0, respectively. The impairment as of December 31, 2023 was related to cash flow impairment for one of the Company’s Gamma Knife units and estimated removal costs of the two Gamma Knife contracts that expired during the year. The Company reviewed its Gamma Knife equipment, in light of available information as of December 31, 2022 and concluded no impairment existed. The Company reviewed it’s PBRT equipment, in light of available information as of December 31, 2023 and 2022 and concluded no impairment exists.

Insurance financing $ — $ 591,000

NOTE 5 - LONG TERM DEBT

On April 9, 2021 the Company along with certain of its domestic subsidiaries (collectively, the “Loan Parties”) entered into a five year $22,000,000 credit agreement with Fifth Third Bank, N.A. (“the Credit Agreement”). The Credit Agreement includes three loan facilities. The first loan facility is a $9,500,000 term loan (the “Term Loan”) which was used to refinance the domestic Gamma Knife debt and finance leases, and associated closing costs. The second loan facility is a $5,500,000 delayed draw term loan (the “DDTL”) which was used to refinance the Company’s PBRT finance leases and associated closing costs, as well as to provide additional working capital. The third loan facility provides for a $7,000,000 revolving line of credit (the “Revolving Line”) available for future projects and general corporate purposes. The Company borrowed $2,500,000 on the Revolving Line as of December 31, 2023, which was paid off in January 2024. The facilities have a five-year maturity, carry a floating interest of LIBOR plus 3.0% and are secured by a lien on substantially all of the assets of the Loan Parties and guaranteed by ASHS. The long-term debt on the consolidated balance sheets related to the Term Loan and DDTL was $10,825,000 and $12,624,000 as of December 31, 2023 and 2022, respectively.

The Revolving Line is charged an unused line fee of 0.25% per annum. The Term Loan and DDTL have interest and principal payments due quarterly. Principal amortization on an annual basis for the Term Loan and DDTL equates to 48% of the original principal loan commitments in years one through five and an end of term payment of the remaining principal balance.

The Credit Agreement contains customary covenants and representations, including without limitation, a minimum fixed charge coverage ratio of 1.25 and maximum funded debt to EBITDA ratio of 3.0 to 1.0 (tested on a trailing twelve-month basis at the end of each fiscal quarter), reporting obligations, limitations on dispositions, changes in ownership, mergers and acquisitions, indebtedness, encumbrances, distributions, investments, transactions with affiliates and capital expenditures. The Loan Parties are in compliance with the Credit Agreement covenants as of December 31, 2023. On January 25, 2024, the Company amended its Credit Agreement to include financing for the equipment in Puebla, see Note 12 - Subsequent Event for further information.

The loan entered into with DFC in connection with the acquisition of GKCE in June 2020 (the “DFC Loan”) was obtained through the Company’s wholly-owned subsidiary, HoldCo, and is guaranteed by GKF. The DFC Loan is secured by a lien on GKCE’s assets. The first tranche of the DFC Loan was funded in June 2020. During the fourth quarter of 2023, the second tranche of the DFC loan was funded to finance the equipment upgrade in Ecuador. The amount outstanding under the first tranche of the DFC Loan is payable in 29 quarterly installments with a fixed interest rate of 3.67%. The amount outstanding under the second tranche of the DFC Loan is payable in 16 quarterly installments with a fixed interest rate of 7.49%. The long-term debt on the consolidated balance sheets related to the DFC loan was $2,464,000 and $1,041,000 as of December 31, 2023 and 2022, respectively. The Company capitalized debt issuance costs of $9,000 and $9,000 as of December 31, 2023 and 2022, respectively, related to maintenance and administrative fees on the DFC Loan.

The DFC Loan contains customary covenants among other covenants and obligations, requirements that the Company maintain certain financial ratios related to liquidity and cash flow as well as depository requirements. On March 28, 2024 the Company received a waiver and amendment from DFC for certain covenants as of December 31, 2023 and through December 31, 2024 and amended other covenants and definitions permanently. The Company expects to be in compliance with all debt covenants pursuant to the DFC Loan as amended and waived at March 31, 2024.

The accretion of debt issuance costs for the years ended December 31, 2023 and 2022, was $46,000 and $84,000, respectively. As of December 31, 2023 and 2022, the unamortized debt issuance costs on the consolidated balances sheets were $164,000 and $198,000.

The following are contractual maturities of long-term debt by year at December 31, 2023, excluding debt issuance costs of $164,000:

NOTE 6 - LEASES

The Company determines if a contract is a lease at inception. Under ASC 842, the Company is a lessor of equipment to various customers. Leases that commenced prior to ASC 842 adoption date were classified as operating leases under historical guidance. As the Company has elected the package of practical expedients allowing it to not reassess lease classification, these leases are classified as operating leases under ASC 842 as well. All of the Company’s lessor arrangements entered into after ASC 842 adoption are also classified as operating leases. Some of these lease terms have an option to extend the lease after the initial term, but do not contain the option to terminate early or purchase the asset at the end of the term. The Company has elected not to recognize right-of-use (“ROU”) assets and lease liabilities that arise from short-term (12 months or less) leases for any class of underlying asset.

The Company’s Gamma Knife and PBRT contracts with hospitals are classified as operating leases under ASC 842. The related equipment is included in medical equipment and facilities on the Company’s consolidated balance sheets (see further discussion at Note 2). As all income from the Company’s lessor arrangements is solely based on procedure volume, all income is considered variable payments not dependent on an index or a rate. As such, the Company does not measure future operating lease receivables.

On November 3, 2021, the Company entered into an agreement to sublease (the “Sublease”) its corporate office located at Two Embarcadero Center, Suite 410, San Francisco, California, where it leased approximately 3,253 square feet for $22,011 per month. The lease expired in August 2023. The Sublease was for $16,195 per month through the existing contract expiration date. The Company also entered into a lease (the “Lease”) agreement for new corporate office space at 601 Montgomery, Suite 1112, San Francisco, CA for approximately 900 square feet for $4,500 per month with a lease expiration date in November 2024. The Company assessed the Lease under ASC 842 and concluded the Lease should be classified as an operating lease.

The Company’s lessee operating leases are accounted for as ROU assets, current portion of lease liabilities, and lease liabilities on the consolidated balance sheets. Operating lease ROU assets and liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The Company’s operating lease contracts do not provide an implicit rate for calculating the present value of future lease payments, so the Company determined its incremental borrowing rate to be in the range of approximately 4.0% and 6.0% by using available market rates and expected lease terms. The operating lease ROU assets and liabilities also include any lease payments made and excludes lease incentives and initial direct costs incurred. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term. The Company’s lessee operating lease agreements are for administrative office space and related equipment, and the agreement to lease clinic space for its stand-alone facility in Lima, Peru. These leases have remaining lease terms of approximately 1 year, some of which include options to renew or extend the lease. As of December 31, 2023, operating ROU assets and lease liabilities were $57,000.

The following table summarizes maturities of lessee operating lease liabilities as of December 31, 2023:

The provision for income taxes differs from the amount computed by applying the U.S. federal statutory tax rate (21% in 2023 and 2022) to income before taxes as follows:

YEARS ENDED December 31,

State income taxes, net of federal benefit 12,000 100,000

As of December 31, 2023, the Company has net operating loss carryforwards for federal and state income tax return purposes of approximately $0 and $2,586,000 that begin to expire in 2029.

Utilization of the net operating loss and credit carryforwards may be subject to an annual limitation due to the ownership change limitations provided by the Internal Revenue Code of 1986, as amended (the “Code”), and similar state provisions. Any annual limitation may result in the expiration of net operating losses and credits before utilization.

At December 31, 2023, the Company has a capital loss carryforward for federal income tax return purposes of approximately $2,679,000,which start to expire in 2024. The Company has capital loss carryforwards for state income tax purposes of approximately $129,000, which starts to expire in 2024.

Due to uncertainty surrounding the realization of impairment losses, capital losses and foreign operating losses in future years, the Company has placed a valuation allowance against a portion of its net domestic and foreign deferred tax assets. The net valuation allowance increased by $17,000 and $0 for the years ended December 31, 2023 and 2022, respectively.

The tax return years 2019 through 2022 remain open to examination by the major domestic taxing jurisdictions to which the Company is subject. Net operating losses generated on a tax return basis by the Company for calendar years 1999 through 2004,2009,2010,2012,2014,2015,2016,2017 and 2018 remain open to examination by the major domestic taxing jurisdictions.

NOTE 7– INCOME TAXES (CONTINUED)

The Company has adopted accounting standards which prescribe a recognition threshold and measurement attribute for the financial statement recognition and measurement of uncertain tax positions taken or expected to be taken in a company’s income tax return, and also provides guidance on derecognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. Additionally, these accounting standards specify that tax positions for which the timing of the ultimate resolution is uncertain should be recognized as long-term liabilities. The Company has made no reclassifications between current taxes payable and long term taxes payable under this guidance.

As of December 31, 2023, the unrecognized tax benefit was $287,000 which, if recognized, will not affect the annual effective tax rate as these unrecognized tax benefits would increase deferred tax assets, which would be subject to a full valuation allowance. A reconciliation of the beginning and ending amount of unrecognized tax benefit is as follows:

YEARS ENDED December 31,

Additions based on tax positions of prior years 9,000 (17,000 )

The Company’s policy for deducting interest and penalties is to treat interest as interest expense and penalties as income taxes. As of December 31, 2023, the Company had $58,000 accrued for the payment of penalties and zero interest related to unrecognized tax benefits. The Company does not expect any material changes to our uncertain tax positions within the next 12 months. The Company believes that it is reasonably possible that a decrease of up to $100,000 in unrecognized tax benefits related to foreign taxes may be necessary within the coming year.

Incentive Compensation Plan

In June 2021, the Company’s shareholders approved an amendment and restatement of the Company’s Incentive Compensation Plan (the “Plan”), that among other things, increases the number of shares of the Company’s common stock reserved for issuance under the Plan to 2,580,000 and extends the term of the Plan by five years to February 22, 2027. The Plan provides that the shares reserved under the Plan are available for issuance to officers of the Company, other key employees, non-employee directors, and advisors. No further grants or share issuances will be made under the previous plans. As of December 31, 2023, approximately 935,000 shares remain available for grant under the Plan.

Under the Plan, a total of 898,000 restricted stock units have been granted, consisting of 53,000 of annual automatic grants to non-employee directors, 328,000 of deferred retainer fees to non-employee members of the Board, 57,000 grants issued in lieu of commission or bonus to employees of the Company, and 460,000 restricted stock units issued to the Executive Chairman of the Board, see further discussion below. Of the total restricted stock units granted under the Plan, 123,000 of them are fully vested but not yet deemed issued and outstanding, 742,000 are fully vested and outstanding, and 33,000 are outstanding as of December 31, 2023.

Changes in restricted stock units, consisting primarily of annual automatic grants, deferred compensation to non-employee directors, shares issued to employees as part of the Company’s bonus plan, and restricted stock units awards to the Executive Chairman of the Board, under the Incentive Compensation Plans during 2023 and 2022 are as follows:

The weighted average grant-date fair value of the options granted during the years 2023 and 2022 was $2.89and $1.49, respectively. There were no options exercised during the year ended December 31, 2023. There were 4,000 options exercised which resulted in 3,000 shares issued, due to cashless exercises, during the year ended December 31, 2022. Total stock-based compensation expense recognized for stock options for the years ended December 2023 and 2022 was $34,000 and $10,000, respectively.

The Company received approximately $5,000 from the exercise of 2,000 options under the share-based arrangements during the year ended December 31, 2022. The remaining options exercised during 2022 were cashless exercises.

At December 31, 2023, there was approximately $156,000of unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan. This cost is expected to be recognized over a period of approximately four years.

The Company’s stock option awards to employees are calculated using the Black-Scholes options valuation model. The Black-Scholes model was developed for use in estimating the fair value of traded options which have no vesting restrictions and are fully transferable. In addition, the Black-Scholes model requires the input of highly subjective assumptions including the expected stock price volatility. The Company’s stock-based awards have characteristics significantly different from those of traded options, and changes in the subjective input assumptions can materially affect the present value estimates. For these reasons, management believes that the existing models do not necessarily provide a reliable single measure of the fair value of its stock-based awards to employees.

The fair value of the Company’s option grants issued during 2023 and 2022 were estimated using assumptions for expected life, volatility, dividend yield, forfeiture rate, and risk-free interest rate which are specific to each award as summarized in the following table. The estimated fair value of the Company’s options is amortized over the period during which the optionee is required to provide service in exchange for the award, usually the vesting period.

The fair value of the Company’s option grants under the Plan in 2023 and 2022 was estimated using the following assumptions:

Expected life (years) 7.0 7.0

Expected forfeiture rate 0.0 % 0.0 %

Expected volatility 50 % 50 %

Dividend yield 0 % 0 %

Risk-free interest rate 3.6 % 3.3 %

The following summarizes the assumption inputs used for the Company’s Black-Scholes calculation:

Expected life (years): The expected term represents the weighted average period that the Company’s stock options are expected to be outstanding.

Expected forfeiture rate: Forfeitures are recognized as they occur.

Expected volatility: The expected volatility was derived from the Company’s historical stock volatility.

Dividend yield: The expected dividend yield was assumed to be zero, as the Company has not previously paid dividends on common stock and has no current plans to do so.

Risk-free interest rate: The risk-free interest rate is based on the interest yield in effect at the date of grant for zero coupon U.S. Treasury notes with maturities approximately equal to the option’s expected term.

Repurchase of Common Stock, Common Stock Warrants and Stock Options

In 1999 and 2001, the Board of Directors approved resolutions authorizing the Company to repurchase up to a total of 1,000,000 shares of its own stock on the open market, which the Board reaffirmed in 2008. There were no shares of the Company repurchased during 2023 or 2022. There are approximately 72,000 shares remaining under this repurchase authorization.

NOTE 9– RETIREMENT PLAN

The Company has a defined-contribution retirement plan (the “Retirement Plan”) that allows for a matching safe harbor contribution. For 2023, the Board of Directors elected to match participant deferred salary contributions up to a maximum of 4% of the participant’s annual compensation. Discretionary profit sharing contributions are allowed under the Retirement Plan in years that the Board does not elect a safe harbor match. During 2023, the Company contributed $43,000 to the Retirement Plan for the safe harbor match for the year ended December 31, 2023. The Company has accrued approximately $17,000 for additional safe harbor matching contribution for the year ended December 31, 2023. Also during 2023, the Company contributed $47,000 to the Retirement Plan for the safe harbor match for the year ended December 31, 2022.

NOTE 10– COMMITMENTS AND CONTINGENCIES

On December 20, 2018, the Company signed Second Amendments to two System Build Agreements for the Company’s second and third Mevion PBRT units. These commitments expired in January 2024 and the Company was not able to utilize this equipment. During the year-ended December 31, 2020, the Company impaired these deposits and wrote-off the deposits and related capitalized interest.

As of December 31, 2023, the Company had commitments to install three Leksell Gamma Knife Esprit Systems (“Esprit”), install one Cobalt-60 reload with software, purchase one Gamma Plan workstation, purchase one Linear Accelerator (“LINAC”) system, and purchase one Magnetic Resonance imaging guided LINAC (“MR LINAC”). The LINAC, MR LINAC and one Esprit will be placed at future customer sites. The remaining Esprit upgrades and Cobalt-60 reload are scheduled to occur during 2024 at existing customer sites. The Company also has one commitment to de-install a Gamma Knife unit at an existing customer site. The Company’s LINAC installation in Puebla was in process at December 31, 2023 and the Company made substantial payments towards the project during 2023. In January 2024, the Company amended the Credit Agreement to include financing for this project. At December 31, 2023, the Company had commitments remaining for some of the ancillary equipment in Puebla. Total Gamma Knife and LINAC commitments as of December 31, 2023, were $15,925,000. There are no deposits on the consolidated balance sheets related to these commitments as of December 31, 2023. It is the Company's intent to finance substantially all of these commitments. There can be no assurance that financing will be available for the Company’s current or future projects, or at terms that are acceptable to the Company. However, the Company currently has cash on hand of $13,808,000 and a line of credit of $7,000,000 to fund these projects, if necessary. The Company borrowed $2,500,000 on the Revolving Line as of December 31, 2023, which was paid off in January 2024.

On September 4, 2022, the Company entered into a Maintenance and Support Agreement with Mevion (the “Mevion Service Agreement”), which provides for maintenance and support of the Company’s PBRT unit at Orlando Health from September 2022 through April 2026. The agreement requires an annual prepayment of $1,865,000 for the current contractual period (one year). This payment portion was recorded as a prepaid contract and will be amortized over the one-year service period.

As of December 31, 2023, the Company had commitments to service and maintain its Gamma Knife and PBRT equipment. The service commitments are carried out via contracts with Mevion, Elekta and Mobius Imaging, LLC. The Company’s commitments to purchase two LINAC systems also include a 9-year and 5-year agreement to service the equipment, respectively. Total service commitments as of December 31, 2023 were $14,805,000. The Gamma Knife and certain other service contracts are paid monthly, as service is performed. The Company believes that cash flow from cash on hand and operations will be sufficient to cover these payments.
