ITEM 1A. RISK FACTORS

In addition to the other information in this report, the following factors could affect our future business, results of operations, cash flows or financial position, and could cause future results to differ materially from those expressed in any of the forward-looking statements contained in this report. The risks and uncertainties described below are not the only ones we face. Additional risks not currently known to us or other factors not perceived by us to present significant risks to our business at this time also may impair our business operations.

Company, Industry and Economic Risk

If the Company is not successful at diversifying its business model, its revenues and profitability may decline.

The Company has historically relied on Gamma Knife unit placement and a PBRT system to provide its revenues. Currently, there is a limited market for Gamma Knife equipment and PBRT systems. As a result, we plan to adapt our business model to place other types of stereotactic radiosurgery and advanced radiation therapy equipment, including through the completion of the RI Acquisition, in addition to Gamma Knife units and PBRT systems. This will constitute an expanded product mix for the Company and there can be no assurance that we can successfully adapt our historical business model to these new product offerings. If we are not successful, our revenues and profitability could decline substantially as existing contracts expire and are not renewed.

The Federal reimbursement rate for Gamma Knife treatments may not provide the Company with an adequate return on its investment.

Congress enacted legislation in 2013 that significantly reduced the Medicare reimbursement rate for outpatient Gamma Knife treatment by setting it at the same amount paid for linear accelerator-based radiosurgery treatment. Gamma Knife treatment has been relatively stable during the last five years. There can be no assurance that CMS reimbursement levels will be maintained at levels providing the Company an adequate return on its investment. Any future reductions in the reimbursement rate would adversely affect the Company’s revenues and financial results.

The Company's revenue sharing is subject to payor mix variability which could negatively impact the Company's revenue and financial results.

The Company’s average reimbursement rate for its revenue sharing and retail customers is dependent on the percentage mix of government associated payors and commercial managed care payors. Commercial and managed care payors tend to reimburse at a higher level than government payors. Therefore, a shift in payor mix to a higher level of government payors will reduce the Company’s average reimbursement rate per treatment.

The Company’s capital investment at each site is substantial and the Company may not be able to fully recover its costs or capital investment which could have a material negative impact on its revenues and financial results.

Each Gamma Knife, PBRT or advanced LINEAR accelerator device requires a substantial capital investment. In some cases, we contribute additional funds for capital costs and/or annual operating and equipment related costs such as marketing, maintenance, insurance and property taxes. Due to the structure of our contracts with medical centers, there can be no assurance that these costs will be fully recovered or that we will earn a satisfactory return on our investment, which could have a material negative impact on our revenues and financial results. Additionally, the Company is obligated to remove the equipment at the end of the lease term. In the event the customer does not purchase the equipment from the Company or the Company is not able to trade in the equipment, the Company is required to remove the equipment and record an Asset Retirement Obligation (“ARO”).

The market for the Gamma Knife is limited and the Company may not be able to place additional Gamma Knife units which could negatively impact the Company's revenue and financial results.

There is a limited market for the Gamma Knife, and the market in the United States may be mature. The Company has begun and continued operation at only five new Gamma Knife sites in the United States since 2011. Due to the substantial costs of acquiring a Gamma Knife unit, we must identify medical centers that possess neurosurgery and radiation oncology departments capable of performing a large number of Gamma Knife procedures. There can be no assurance that we will be successful in placing additional units at any sites in the future. In recognition of the Gamma Knife's limited growth opportunity, the Company has expanded its product mix to include LINACs, MR LINACs, PET LINACs and is continuing to market PBRT units, but there can be no assurance that the Company will be successful in placing these products with customers. The Company’s existing contracts with its customers are fixed in length and there can be no assurance that the customers will wish to extend the contract beyond the end of the term.

The Company has incurred debt and may incur additional debt to finance its operations and if the Company is unable to secure additional credit in the future its operations and profits will be negatively impacted.

The Company’s business is capital intensive. 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, 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. On January 25, 2024, the Company and Fifth Third entered into the First Amendment which added an additional $2,700,000 term loan, and, on December 18, 2024 the Company entered into the Second Amendment which added another $7,000,000 term loan. In June 2020, the Company’s wholly-owned subsidiary, HoldCo, entered into the DFC Loan in connection with the acquisition of GKCE. The first tranche of the DFC Loan was funded in June 2020 in the amount of $1,425,000. 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 Company’s combined long-term debt, net, totaled $20,182,000 as of December 31, 2024. The Credit Agreement is secured by a lien on substantially all of the assets of the Company and certain of its domestic subsidiaries and the DFC Loan is secured by a lien on GKCE’s assets. The Credit Agreement includes a $7,000,000 Revolving Line available for future projects and general corporate purposes. Depending on the Company’s financing requirements and market conditions, the Company may seek to finance its operations by incurring additional long-term debt in the future. The Company’s current level of debt may adversely affect the Company’s ability to secure additional credit in the future, and as a result may affect operations and profitability. If a default on debt occurs in the future, the Company’s creditors would have the ability to accelerate the defaulted loan, to seize the Company’s assets with respect to which default has occurred, and to apply any collateral they may have at the time to cure the default.

Table of Contents

The Company’s debt agreements contain restrictions that limit its flexibility in operating its business, and the Company may be required to repay the outstanding indebtedness in an event of default, which would have an adverse effect on our business.

The Credit Agreement and the DFC Loan contain various covenants that limit the Company’s ability to engage in specified types of transactions. These covenants subject the Company to various restrictions that limit the Company from, among other activities, creating any unpermitted liens to exist on its assets, incurring additional indebtedness, causing a sale of all or substantially all of its assets, effecting a merger, paying dividends or other distributions on capital stock, redeeming shares of capital stock, engaging in transactions with affiliates, or undertaking lease obligations above certain thresholds. Moreover, under certain of our credit arrangements we have granted the lender a security interest in Company assets as security for our obligations.

In addition, the Company is obligated to comply with certain financial-reporting requirements, financial ratios, and liquidity and leverage thresholds under certain covenants in its Credit Agreement and DFC Loan. The Company’s ability to meet those financial ratios and tests can be affected by events beyond our control, including prevailing economic, financial market and industry conditions and the Company cannot give assurance that it will be able to satisfy such ratios and tests when required.

A breach of any of these covenants could result in a default under the Credit Agreement and the DFC Loan. Upon the occurrence of an event of default, the lenders could elect to declare the amount outstanding under the Credit Agreement or DFC Loan immediately due and payable. 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. The Company’s business, financial condition, and results of operations could be materially adversely affected as a result of any of those events. The Company may seek to enter into an extension of the credit and loan agreements or to enter into a new facility or loan agreement with another lender. However, the Company may not be able to extend the term or obtain other debt financing on terms that are favorable to the Company, if at all, and the Company could be subject to additional restrictions on its business operations. If the Company is unable to obtain adequate financing or financing on satisfactory terms when required, the Company’s ability to support its business growth and to respond to business challenges could be significantly impaired, and its business may be harmed.

As of December 31, 2023 and 2024, HoldCo was not in compliance with all of its debt covenants then in effect pursuant to the DFC Loan. However, on March 28, 2024, the Company obtained a waiver for the covenant non-compliance as of December 31, 2023 (the “DFC Waiver”). On March 3, 2025 the Company received an additional DFC waiver for certain covenants as of December 31, 2024 and through December 31, 2025. However, if a waiver from DFC is required in the future for potential non-compliance, DFC may be unwilling to provide a waiver and could, as a result, among other remedies, accelerate the repayment of the debt obligations outstanding under the DFC Loan, which could have a material adverse effect on the Company’s financial condition.

The Company’s failure to file certain financial statements in connection with the RI Acquisition pursuant to Rules 8-04 and 8-05 of Regulation S-X and Item 9.01 of Form 8-K will limit the Company’s ability to raise capital.

On May 7, 2024, the Company filed a Current Report on Form 8-K to report the completion of the Company’s acquisition of 60% of the equity interests in each of the RI Companies from GenesisCare. Based on information available to the Company, the Company believes that the acquisition would qualify as a “significant” acquisition under Rule 1-02(w) of Regulation S-X and as a result, under Rules 8-04 and 8-05 of Regulation S-X, the Company would be required to provide (i) audited financial statements for the RI Companies as of and for the period ended June 30, 2023 and unaudited interim financial statements to the extent applicable (the “8-04 financial information”), and (ii) pro forma historical financial information combined to reflect the RI Companies’ financial information for the most recent fiscal year and interim period (the “8-05 financial information” and, together with the 8-04 financial information, the “S-X financial information”).

The Company purchased its interest in the RI Companies as part of the sale of certain of GenesisCare’s assets in its bankruptcy proceedings which were initiated in early June 2023. Due to the lack of reliable financial information for the RI Companies following the protracted bankruptcy proceedings, the Company is not able to obtain financial information sufficient to be able to provide the S-X financial information. The Company, therefore, is not in compliance with Rules 8-04 and 8-05 of Regulation S-X. Unless the Company files the S-X financial information, the Securities and Exchange Commission will not declare effective registration statements or post-effective amendments filed by the Company until twelve months following the date on which the Company has filed a periodic report with the Securities and Exchange Commission that meets the requirements of Regulation S-X, and affiliates will be not be permitted to make sales of securities pursuant to Rule 144 pursuant to the Securities Act of 1933, as amended.

The Company may fail to successfully integrate the interests acquired in the RI Acquisition with its legacy business in a timely manner, which could have a material adverse effect on the Company’s business, financial condition, results of operations, or cash flows, or the Company may fail to realize all of the expected benefits of the RI Acquisition, which could negatively impact the Company’s future results of operations.

The integration of any acquisitions, including the RI Acquisition, completed during the 2024 fiscal year, requires significant time and resources. A failure by the Company to successfully integrate the businesses, operations, and contractual obligations of the RI Companies with the Company’s existing business in a timely manner could have a material adverse effect on the Company’s business, financial condition, cash flows, or results of operations. Acquiring a majority interest in the RI Companies, assuming obligations under the commercial payor contracts set forth in the IPA, and integrating the businesses of the three turn-key radiation therapy cancer centers that the RI Companies operate in Rhode Island has involved and likely will continue to involve several risks that could undermine the success and expected benefits of the RI Acquisition. Such risks include but are not limited to the following:

If the Company is not successful in addressing these risks effectively, the Company’s business and operations could be impaired.

The Company’s failure to remediate its material weakness in its internal control over financial reporting could adversely affect its ability to report its financial condition and results of operations in a timely and accurate manner, and may adversely affect investor confidence, our reputation, and our business operations and financial condition.

The Company is subject to various SEC reporting and other regulatory requirements. Effective internal controls over financial reporting are necessary for the Company to provide reliable financial reports and, together with adequate disclosure controls and procedures, are designed to prevent fraud and material errors in transactions and to fairly present financial statements. Any failure to implement required new or improved controls, or difficulties encountered in their implementation, could cause us to fail to meet our reporting obligations. As of December 31, 2024, the Company’s principal executive officer and principal financial officer carried out an evaluation of the effectiveness of the Company’s “disclosure controls and procedures” (as defined in the Rules 13a-15(e) and 15d-15(e)) of the Exchange Act) and concluded that the disclosure controls and procedures were not effective due to a material weakness in the Company’s internal control over financial reporting. The Company has limited accounting and finance personnel and expanded its operations in 2024, which impacted the Company’s ability to maintain an effective control environment. While the Company has processes to identify and appropriately apply applicable accounting requirements, the Company plans to continue to enhance its systems, processes, and human capital resources with respect to its accounting and finance functions. The elements of the Company’s remediation plan can only be accomplished over time with the addition of experienced accounting and finance employees and, where necessary, external consultants, and with the implementation of enhanced accounting systems and financial close processes.

The Company has commenced remediation of the above discussed material weakness as it has expanded its accounting staff and personnel since late in fiscal 2024. The Company will continue to evaluate its accounting and finance staffing needs as well as make planned enhancements to its systems and improvements to its financial reporting processes. However, there can be no assurance that the Company will be successful in remediating the material weakness in its internal control over financial reporting. If the Company is unable to successfully complete its remediation efforts or favorably assess the effectiveness of its internal control over financial reporting, the Company’s operating results, financial position, stock price, and ability to accurately report its financial results and timely file its SEC reports could be adversely affected.

Additionally, any failure to maintain effective controls could limit the Company’s ability to prevent or detect a misstatement of our accounts or disclosures that could result in material misstatements of the Company’s annual or interim financial statements. In such a case, the Company may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to the listing requirements of the NYSE American. In addition, the Company could be subject to sanctions or investigations by the SEC, the NYSE American, or other regulatory authorities as well as shareholder litigation which would require additional financial and management resources. Failures in internal controls may also negatively affect investor and customer confidence in Company management or result in adverse publicity and concerns from investors and customers, any of which could have a negative effect on the price of the Company’s common stock, subject the Company to regulatory investigations, potential penalties, or stockholder litigation, and have a material adverse impact on the Company’s business and financial condition.

The Company’s cash flow could become insufficient to service its debt due to financial, business, and other factors.

The Company’s ability to make scheduled payments of the principal and interest on its indebtedness depends on the Company’s financial condition and operating performance, which is subject to economic and competitive conditions and to certain financial, business, and other factors. There can be no assurance that the Company will maintain a level of cash flow from operating activities sufficient to permit it to pay the principal of and any interest on its indebtedness. If the Company’s cash flow and capital resources are insufficient to fund its debt obligations, the Company may be forced to delay investments and capital expenditures, to seek additional capital, or to restructure or refinance its indebtedness. There can be no guarantee that those alternative measures will be available, either at all or on terms that are favorable to the Company, or that they will be successful even if available in allowing the Company to meet its debt-service obligations. In the absence of such operating results and resources, the Company could experience liquidity issues, which could force the Company to take alternative measures to satisfy its debt obligations, such as selling assets, restructuring debt, or obtaining additional equity capital on potentially onerous or highly dilutive terms. The Credit Agreement and DFC Loan restrict the Company’s ability to dispose of assets and to use the proceeds from such dispositions, so the Company may be restricted from taking certain measures, such as conducting an asset sale, to meet its debt-service obligations. The ability to refinance indebtedness would also depend on the general state of capital markets and on the Company’s financial condition, neither of which can be predicted at this time.

A small number of customers account for a major portion of our revenues and the loss of any one of these significant customers could have a material adverse effect on the Company's business and results of operations.

A limited number of customers have historically accounted for a substantial portion of the Company’s total revenue, and the Company expects such customer concentration to continue for the foreseeable future. For example, in 2024, two customers individually accounted for approximately 35% and 27% of the Company’s revenue. The loss of a significant customer or a significant decline in the business from the Company’s largest customers could have a material adverse effect on the Company’s business and results of operations.

The Company occupies many of its facilities under long-term leases and the Company may not be able to renew its leases at the end of their terms.

The Company leases many of the facilities where it holds its equipment. At the end of the lease term for a facility, the Company may be unable to renew the lease without substantial additional costs, if at all. If we are unable to renew our facility leases, we may be required to relocate or close a facility. Additionally, due to the nature of its radiation equipment, there can be a long lead time to prepare space for holding its equipment and substantial cost involved in moving the equipment should the Company need to change locations. The failure to be able to obtain leased space when required or the costs of relocation could have a material adverse effect on our business and results of operations.

The market for the Company’s services is competitive and if the Company is not able to compete its business and results of operations could be negatively impacted.

The Company estimates that there are two other companies that actively provide alternative, non-conventional Gamma Knife financing to potential customers. The Company’s relationship with Elekta, the manufacturer of the Leksell Gamma Knife unit, is non-exclusive, and the Company has lost sales to customers that chose to purchase a Gamma Knife unit directly from Elekta. The Company also has several competitors in the financing of proton therapy projects. The Company’s business model differs from its competitors, but there can be no assurances that the Company will not lose placements to its competitors. In addition, the Company may continue to lose future sales to customers purchasing equipment directly from manufacturers. There can be no assurance that the Company will be able to successfully compete against others in placing future units and if the Company is not able to compete its business and results of operations could be negatively impacted.

There are alternatives to the Gamma Knife and medical centers could choose to use other radiosurgery devices instead of the Gamma Knife.

Other radiosurgery devices and conventional neurosurgery compete against the Gamma Knife. Each of the medical centers targeted by the Company could decide to acquire another radiosurgery device instead of a Gamma Knife to perform cranial radiosurgery. In addition, neurosurgeons who are responsible for referring patients for Gamma Knife surgery may not be willing to make such referrals for various reasons, instead opting for invasive surgery. Because of these competing alternatives, there can be no assurance that the Company will be able to secure a sufficient number of future sites or Gamma Knife procedures to sustain its profitability and growth and accordingly there may be a material negative impact on the business and results of operations of the Company.

International operations make the Company vulnerable to risks associated with doing business in foreign countries that can affect its business, financial condition, results of operations and cash flows.

The Company installed a Gamma Knife unit in Lima, Peru in 2017, acquired a Gamma Knife unit operation in Guayaquil, Ecuador in 2020, and installed a LINAC in Puebla, Mexico which began treating patients in July 2024. International operations can be subject to exchange rate volatility, which could have an adverse effect on our financial results and cash flows. In addition, international operations can be subject to legal and regulatory uncertainty and political and economic instability, which could result in problems asserting property or contractual rights, potential tariffs, increased compliance costs, increased regulatory scrutiny, foreign customers with longer payment cycles than customers in the United States, potential adverse tax consequences, the inability to repatriate funds to the United States, and the Company’s inability to operate in those locations.

Flaws in the Company’s due-diligence assessment in connection with the equity interests and payor contracts acquired in the RI Acquisition could have a significant negative effect on the Company’s financial condition and results of operations.

The Company conducted due diligence when evaluating the RI Acquisition prior to executing the IPA and during the interim period between signing the IPA and closing the RI Acquisition. The time and costs of the due-diligence process were amplified with respect to the Company’s evaluation of the potential costs and benefits of the RI Acquisition due to the distressed state and bankruptcy of GenesisCare. Despite the thoroughness of the Company’s review, diligence may not have revealed all material issues that could affect the Company’s interests in the RI Companies acquired in the RI Acquisition. In addition, factors outside of the Company’s control could later arise. The Company’s failure to identify material issues specific to the business and operations of the RI Companies and the liabilities and obligations the Company assumed from the assignment of the payor contracts, during the Company’s due diligence process, could negatively impact the Company’s financial condition and results of operations.

New technology and products could result in making the Company's equipment obsolete which could have a material adverse impact on its business and results of operations.

There is constant change and innovation in the market for highly sophisticated medical equipment. New and improved medical equipment can be introduced that could make the Gamma Knife technology obsolete and that would make it uneconomical to operate. In 2006, Elekta introduced a new model of the Gamma Knife, the Perfexion, which the Company has implemented at all of its domestic sites. The Perfexion can perform procedures faster than previous Gamma Knife models and it involves less health care personnel intervention. In 2015, Elekta introduced the Leksell Gamma Knife Icon TM. The Perfexion is upgradeable to the Icon platforms which has enhanced imaging capabilities allowing for treatment without a head frame and the treatment of larger tumors. In 2022, Elekta introduced an upgrade to the Icon, called the Esprit. Existing model 4(C)s of the Gamma Knife are not upgradeable to the Perfexion model. Currently, four of the Company’s eight Gamma Knife units in the United States are Esprits and all of the Company’s eight Gamma Knife units are Perfexion models, one of which has the Icon upgrade. The Company’s equipment in Ecuador was upgraded to a Perfexion with Icon in November 2023. The Company is in the process of upgrading the equipment in Peru from a Model 4(C) to the Esprit and expects to complete this upgrade during the second quarter of 2025. The failure to acquire or use new technology and products could have a material adverse effect on our business and results of operations.

Any failure, interruption, or breach in security of the Company’s information technology (“IT”) infrastructure due to a cyber-attack or other security incident could cause the Company to incur financial penalties and losses, reputational damage, and legal liability, which could have a material adverse effect on the Company’s business, financial condition, and results of operations.

The Company’s ability to carry out its internal and external business operations depends in part on an IT infrastructure that includes computer systems, hardware, software, online sites, servers, networks, and other IT products and services, some of which are owned and managed by third-party service providers and suppliers. Although the Company takes steps to safeguard its IT infrastructure, cybersecurity risks are an evolving and pervasive threat to the Company’s business, operations, and financial performance. Security incidents that the Company must protect against include unauthorized access of the Company’s IT systems, breaches of the Company’s data and confidential information, sophisticated malware, advanced phishing and social-engineering ploys, cyber-attacks, and commercial-software vulnerabilities that are integrated into the Company’s or any of its suppliers’ or service providers’ IT systems. While the Company strives to maintain the integrity and confidentiality of its data, systems, and information and to protect it from internal and external cybersecurity threats by taking the preventative measures and abiding by the security protocols identified in “Item 1C. Cybersecurity” below, there is no guarantee that the IT infrastructure developed by the Company and the cybersecurity measures implemented by the Company will be successful in preventing and defending against the evolving and increasingly sophisticated range of cyber incidents that the Company could be exposed to. Furthermore, there can be no assurance that the Company’s cybersecurity risk management strategy and processes will be fully implemented, complied with, or effective in safeguarding the Company’s data, systems, and information.

Any actual compromise of or perceived threat to the Company’s IT systems and infrastructure could cause significant legal and financial exposure for the Company, damage the Company’s reputation, and create adverse publicity, which could adversely affect the Company’s business, operations, and financial condition. Any necessary response to a cyber-attack, which could include analyzing a security incident, patching up security vulnerabilities, notifying individuals affected by the incident, determining the materiality of the incident, disclosing the incident in accordance with any applicable legal and regulatory requirements, and responding to any resulting litigation, could also divert the Company’s resources and attention from its growth operations and business objectives, which could further hinder its operational and financial performance.

Macroeconomic conditions could have a material adverse effect on our business, results of operations, and financial condition.

Unfavorable macroeconomic conditions, including low productivity growth, declining business investment, inflationary pressures, fluctuating interests rates, concerns regarding the imposition of tariffs (including retaliatory tariffs in response to tariffs imposed by the United States), concerns regarding the level of U.S. debt, shifts in monetary and fiscal policy, strained international trade relations, and heightened geopolitical pressures, could negatively impact our business, results of operations, and financial condition. Economic downturns may cause hospitals and medical centers to reduce spending on capital-intensive medical equipment, delay lease renewals for the radiation therapy devices, and decrease overall investment in new treatment technologies. Trade policies like tariffs and retaliatory measures, as well as geopolitical tensions in the U.S. and global markets, may cause disruptions to medical equipment supply chains, increase the cost of acquiring advanced radiation therapy technology, and delay the delivery of essential components of our Gamma Knife and LINAC systems.

Economic and inflationary pressure on patients and health care providers, along with prolonged uncertainty in the macroeconomic environment, could result in changes in hospital procurement decisions, reduced demand for elective procedures, and constrained budgets for medical technology investments. These conditions may also weaken investor confidence in the health care sector, reduce access to capital for expansion projects, reduce access to capital for expansion projects, and increase regulatory scrutiny over health care spending and reimbursement policies, all of which could have a material adverse effect on our business, financial condition, and results of operations.

We are subject to risks associated with foreign operations, including political, economic, and regulatory uncertainties.

We operate Gamma Knife and LINAC facilities in Peru, Ecuador, and Mexico. These operations expose us to various risks, including changes in foreign regulations, economic instability, and shifts in health care reimbursement policies. If any of these countries implement stricter health care-related requirements, impose price controls, or experience significant currency fluctuations, our international revenue profitability may be negatively impacted.

The potential impairment of our Gamma Knife portfolio and its salvage value could adversely impact our financial condition and results of operations.

As of December 31, 2024, we determined that our Gamma Knife portfolio had no remaining salvage value, and certain sites experienced equipment impairment or are expected to expire in the second quarter of 2025. Additionally, two sites that recently recognized their salvage value as part of the Esprit upgrade were subsequently impaired. Accordingly, we concluded that there was no salvage value remaining and the Company recognized equipment impairment as of December 31, 2024.

The impairment of equipment and change in estimate of salvage value could have a material adverse effect on our financial condition and results of operations. If additional impairments occur in the future, we may be required to recognize further losses on the write-down of impaired assets and incur additional removal costs for expired Gamma Knife units, which could negatively impact our reported earnings. Additionally, the continued aging of our equipment portfolio may necessitate increased capital expenditures to replace or upgrade systems, which could increase our financial burden.

Stock Ownership Risk

The trading volume of the Company’s common stock is low.

Although the Company’s common stock is listed on the NYSE American, the Company’s common stock has historically experienced low trading volume. Reported average daily trading volume in our common stock for the three-month period ended December 31, 2024 was approximately 21,000 shares. It is not likely that a further increase in an active trading market in the Company’s common stock will develop in the future. Limited trading volume subjects the Company’s common stock to greater price volatility and may make it difficult for shareholders to sell their shares in a quantity or at a price that is attractive.

Table of Contents

Our officers, directors and principal shareholders collectively own a substantial portion of our common stock.

Collectively, our officers and directors beneficially own approximately 23.2% of our outstanding common stock, with Raymond Stachowiak, the Executive Chairman of the Board, beneficially owning approximately 22.8% of our common stock. As a result, investors may face challenges in affecting matters involving our Company, including:

● any determinations with respect to mergers or other business combinations;

● our acquisition or disposition of assets; and

● our corporate financing activities.

Our officers, directors, and principal shareholders may act in concert to significantly influence these and other matters requiring shareholder approval. Furthermore, this concentration of voting power could have the effect of delaying, deterring, or preventing a change of control or other business combination that might otherwise be beneficial to our shareholders. This significant concentration of share ownership may also adversely affect the trading price for our common stock because investors may perceive disadvantages in owning stock in a company in which a small number of shareholders hold a significant ownership interest.

We do not anticipate paying dividends on our common stock.

We do not expect to pay or declare dividends in the foreseeable future. The declaration of dividends is subject to the discretion of our board of directors and will depend on various factors, including our operating results, financial condition, future prospects, covenants in documents governing our debt obligations and any other factors deemed relevant by our board of directors. You should not rely on an investment in our company if you require dividend income from your investment in our company. The success of your investment will likely depend entirely upon any future appreciation of the market price of our common stock, which is uncertain and unpredictable. There is no guarantee that our common stock will appreciate in value.

ITEM 1C. CYBERSECURITY

The Company recognizes the importance of securing its information, devices, and data and the IT systems it relies on to conduct its business. The Company has established its Network, Information, and Data Security Policy Guidelines (the “NIDSP Guidelines”) designed to protect the integrity and confidentiality of data and information belonging to or being exchanged by the Company and its employees, partners, customers, service providers, and suppliers and to safeguard that information and the Company’s IT infrastructure from unauthorized access, use, disclosure, alteration, and destruction.

Risk Management and Strategy

The protections, procedures, and controls set forth in the NIDSP Guidelines demonstrate the Company’s attention to and prioritization of cybersecurity as a component of its overall strategy and system for managing risks. The NIDSP Guidelines include five policies described below, that together define the Company’s strategy and practices for managing cybersecurity threats and mitigating cybersecurity risks.

The Company’s NIDSP Guidelines and policies apply not only to the Company’s employees and consultants but also to any third parties that access or utilize the Company’s information and systems. Such third parties may include the Company’s service providers, customers, suppliers, contractors, consultants, and any other individuals the Company conducts business with. The IT infrastructure that the Company has developed in accordance with the NIDSP Guidelines is designed to monitor both internal and external cybersecurity risks. The NIDSP Guidelines equip the Company with the tools and systems necessary to recognize, address, and protect against risks associated with its third-party interactions.

Cybersecurity Governance

The Company’s IT Manager and executive team is responsible for the day-to-day management of cybersecurity risks, while the Company’s Board of Directors has responsibility for oversight of risk management.

As part of the Company’s framework for cybersecurity risk oversight and governance, the Company’s network, information, and data-security policies set forth in the NIDSP Guidelines are enforced by the Company’s IT Manager and/or its executive team. The IT Manager is an employee designated by the Company to manage the Company’s security policies and program. The IT Manager is tasked with ensuring that the Company maintains compliance with the Company’s security policies and any applicable security regulations. The IT Manager is responsible for: (i) implementing the Company’s security policies; (ii) disseminating the Company’s security policies to all employees; (iii) establishing a training program for all employees and users covered by the Company’s IT security policy to notify them of the Company’s security policies, train and re-train them to comply with the Company’s IT security program, and educate them on the importance of data security; (iv) performing any ongoing testing or analysis of the Company’s security infrastructure, policies, and procedures; and (v) updating the NSP and any other policies and guidelines as needed to comply with applicable regulations and to stay up to date with the changing IT security landscape.

The IT Manager works closely with the Company’s management and executive team to determine the Company’s IT-related needs, to evaluate the sufficiency of the Company’s data-governance policies and practices, to keep the Company’s management informed of notable cybersecurity-related updates, to review its security-related policies, and to identify ways to strengthen the systems and procedures implemented by the Company to detect, assess, and manage data risks.

In the event of the detection of an actual or suspected cybersecurity incident, the Company's IT Team, lead by the IT Manager, assesses the incident as “minimal”, “low", “moderate” or “high”. Incidents assessed at a minimal or low risk are reported to Company’s management and the Executive Chairman of the Board and the Executive Chairman of the Board may share this information with the Board. Incidents assessed at a moderate or high risk are reported to Company’s management, the Executive Chairman of the Board, and the Company’s Board of Directors.

Notwithstanding the Company’s cybersecurity-related policies, procedures, and governance framework, the ever-present threat of a cyber-attack, data breach, or other security incident is pervasive. The increasingly sophisticated nature of the tactics used to circumvent IT security safeguards makes cybersecurity threats increasingly difficult to detect and respond to. While the Company does not believe its business strategy, results of operations, or financial condition have been materially adversely affected by any cybersecurity threats or incidents, there is no assurance that the Company will not be materially affected by such threats or incidents in the future. Accordingly, the Company will continue to monitor cybersecurity risks and strive to invest in and strengthen its cybersecurity infrastructure.

ITEM 6. [RESERVED]

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 nine Gamma Knife systems and one PBRT system as of December 31, 2024, where a contract exists between the hospital and the Company. The Company also owns and operates two single-unit Gamma Knife facilities in Lima, Peru and Guayaquil, Ecuador, one single-unit radiation therapy facility in Puebla, Mexico, and as a result of the completion of the RI Acquisition on May 7, 2024, the Company also has an interest in and operates three single-unit radiation therapy facilities in Rhode Island. These facilities constitute the direct patient services segment, 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 5

Fee Per Use 4 5

Medical Equipment Leasing ("Leasing") - Gamma Knife 9 10

Leasing - Proton Bream Radiation Therapy 1 1

Leasing - Total 10 11

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

Direct Patient Services ("Retail") - LINAC 4 —

Direct Patient Services ("Retail") - Total 6 2

The Company had two contracts expire in the second and third quarters of 2023, respectively, and one in November 2024. In February 2025, the Company and one of its customer mutually agreed to terminate their lease agreement prior to the contract term, and the Company expects a fourth contract to expire in the second quarter of 2025. The Company has one customer contract that was upgraded to the Esprit in January 2025. A summary of the Company’s procedure volumes for fiscal years 2024 and 2023 are set forth in the table below.

Volume

Increase Increase

PBRT Procedures (medical equipment leasing) 5,139 5,369 (230 ) (4.3 )%

LINAC Procedures (direct patient services) 14,662 — 14,662 *

The decrease in Gamma Knife volume during 2024 in the leasing segment was primarily due to the expiration of two contracts in the second and third quarters of 2023 and a third contract that expired in November 2024, respectively. Same center procedures decreased 15% compared to 2023, partially due to downtime for the upgrade of one Gamma Knife system to the Esprit during the second quarter of 2024 and other normal, cyclical fluctuations. The Company’s PBRT unit was impacted by several hurricanes during 2024, which drove lower procedure volume at that location.

The increase in Gamma Knife volume during 2024 in the retail segment was due to improved marketing and physician outreach at the Company’s international locations. In addition, the Company’s Gamma Knife unit in Ecuador was upgraded to the Esprit and received a Cobalt-60 reload in November 2023, providing for faster procedure time.

The LINAC procedure volume during 2024 was the result of the completion of the RI Acquisition in May 2024 and the beginning of the Company’s treatment of patients at its LINAC facility in Puebla, Mexico. On May 7, 2024, the Company acquired 60% of the interests of the RI Companies. The RI Companies operate three, existing, stand-alone radiation therapy cancer centers in Woonsocket, Warwick and Providence, Rhode Island. In July 2024, the Company began treating patients at a stand-alone LINAC facility in Puebla, Mexico.

Reimbursement

CMS established a 2025 delivery code reimbursement rate of approximately $7,645 ($7,420 in 2024) for a Medicare Gamma Knife treatment. The approximate CMS reimbursement rates for delivery of PBRT for a simple treatment without compensation for 2025 is $578 ($561 in 2024) and $1,276 ($1,362 in 2024) 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.

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

estimated useful lives of property and equipment and its salvage values, impairment of property and equipment, business combinations, and revenue recognition for revenue sharing customers, 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 nine Gamma Knife systems and one PBRT system as of December 31, 2024. 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 also owns and operates two single-unit Gamma Knife facilities in Lima, Peru and Guayaquil, Ecuador, one single-unit radiation therapy facility in Puebla, Mexico, and following the RI Acquisition on May 7, 2024, the Company also owns a 60% interest in and operates three single-unit radiation therapy facilities in Rhode Island, collectively, the retail segment.

Rental Revenue from Medical Equipment Leasing (“Leasing”)

The Company recognizes revenues 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 typically have a ten-year term and are classified as either fee per use or revenue sharing. Fee per use 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 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 statements of income. For the years ended, December 31, 2024 and 2023, the Company recognized leasing revenue of approximately $15,629,000 and $17,772,000 under ASC 842, respectively, of which approximately $9,952,000 and $10,133,000 were for PBRT services, respectively.

Revenue sharing arrangements amounted to approximately 47% and 70% of total revenue for the years ended December 31, 2024 and 2023, 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, 2024, 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 six and nine months, following issuance of invoice. The Company did not capitalize any incremental costs related to the fulfillment of its customer contracts.

On May 7, 2024, the Company acquired 60% of the interests of the RI Companies. The RI Companies operate three, existing, stand-alone radiation therapy cancer centers in Woonsocket, Warwick and Providence, Rhode Island, where contracts exist between the Company’s facilities and the individual patients treated at the facility. Under ASC 606, the Company acts as the principal in these transactions and provides, at a point in time, a single performance obligation, in the form of radiation therapy treatment. The Company’s stand alone radiation therapy facility in Puebla, Mexico is also accounted for under ASC 606. Revenue related to radiation therapy is recognized at the expected amount to be received, based on insurance contracts and payor mix, 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. Payment terms at these facilities are typically prepaid for self-pay patients and insurance providers are paid net 30 to 60 days. The Company did not capitalize any incremental costs related to the fulfillment of its customer contracts. The Company also concluded these facilities are part of its retail segment, see further discussion below.

Accounts receivable under ASC 606 at December 31, 2024 and January 1, 2024 were $11,229,000 and $1,626,000. Accounts receivable under ASC 606 at December 31, 2023 and January 1, 2023 were $1,626,000 and $1,119,000. For the years ended December 31, 2024 and 2023, the Company recognized retail revenues of approximately $12,556,000 and $3,553,000 under ASC 606, respectively.

Equipment Sales

During the year-ended December 31, 2024, the Company sold one of its Gamma Knife Perfexion units with an Icon upgrade to the customer it was leased to and recorded a net gain on equipment sale. 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 revenues of $155,000 and $200,000 on the sale of equipment for the years ended December 31, 2024 and 2023.

Salvage Value on Equipment

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 are 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 December 31, 2023, the Company had seven domestic Gamma Knife units with salvage value ranging from $140,000 to $300,000. As of December 31, 2024, the Company reduced its estimate of salvage value for the remaining five Gamma Knife units to $0. Prior to this change, the Company had five Gamma Knife units with salvage value ranging from $175,000 to $300,000. This change in estimate was made as of December 31, 2024, therefore, there was no impact for the current year, but this change in estimate will impact future periods.

See Note 3 - Property and Equipment to the consolidated financial statements for further discussion on salvage value.

Impairment of Long-lived Assets

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, 2024 and 2023, the Company recognized a loss on the write down of impaired assets of $3,084,000 and $940,000, respectively. Fluctuations in the Company’s projections of cash flows may result in a 5% to 10% change in the impairment write-down by approximately $87,000 to $174,000, as of December 31, 2024.

See Note 3 - Property and Equipment for further discussion.

Business Combinations

Business combinations are accounted for under ASC 805 Business Combinations (“ASC 805”) using the acquisition method of accounting. Under the acquisition method of accounting, all assets acquired, identifiable intangible assets, liabilities assumed and applicable non-controlling interests are recognized at fair value as of the acquisition date. Costs incurred associated with the acquisition of a business are expensed as incurred. The allocation of purchase price requires management to make significant estimates and assumptions, especially with respect to tangible assets, any intangible assets identified and non-controlling interests. These estimates include, but are not limited to, a market participant’s expectation of future cash flows from acquired customers, acquired trade names, useful lives of acquired assets, and discount rates. Physical deterioration and asset replacement costs were significant variables in the Company’s estimate for fair value of the medical equipment acquired. Fluctuations in these variables may result in a 5% to 10% change in the estimate, which could increase or decrease the fair value of medical equipment acquired as of December 31, 2024, by approximately $120,000 to $240,000. Lease term, renewal of lease terms, square footage allocation, and market lease rates were significant variables in the Company’s estimate for fair value of the facilities acquired. Fluctuations in these variables may result in a 5% to 10% change in the estimate, which could increase or decrease the fair value of leaseholds acquired as of December 31, 2024, by approximately $235,000 to $470,000.

See Note 12 - Rhode Island Acquisition to the consolidated financial statements for further discussion on acquisitions.

Accounting pronouncements issued andnotyet adopted - 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.

In November 2024, the FASB issued ASU 2024-03 Income Statement - Reporting Comprehensive Income - Expense DisaggregationDisclosures (“ASU 2024-03”) which requires entities to (1) disclose amounts of (a) purchase of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and, (e) depreciation, depletion, and amortization recognized as part of oil-and gas-producing activities, (2) include certain amounts that are already required to be disclosed under current Generally Accepted Accounting Principles in the same disclosures as other disaggregation requirements, (3) disclose a qualitative description of the amounts remaining in relevant expense captions that are not necessarily disaggregated quantitatively, and (4) disclose the total amount of selling expenses, in annual reporting periods, an entity’s definition of selling expense. ASU 2024-03 is effective for annual reporting periods beginning after December 15, 2026 and interim reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating ASU 2024-03 to determine the impact it may have on its consolidated financial statements.

2024 Results

For each of the years ended December 31, 2024 and 2023, 56% and 83% of the Company’s revenue was derived from the leasing segment, respectively, and 44% and 17% from the Company’s retail segment, respectively. For the year ended December 31, 2024, 35% of the Company’s revenue was derived from its PBRT business, 34% was derived from its Gamma Knife business, 30% was derived from its LINAC business, and 1% was derived from equipment sales. 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.

TOTAL REVENUE

Increase

Total revenue in 2024 increased 32.9% compared to 2023 primarily due to revenue generated from the Company’ssingle-unit radiation therapy facility in Puebla, Mexico, which began treating patients in July 2024, and revenue generated by the three single-unit radiation therapy facilities owned by the RI Companies, which the Company acquired a 60% interest in on May 7, 2024. Revenues from the Company’s leasing segment decreased $1,988,000 in 2024 compared to 2023 due to a decrease in PBRT volumes and due to the expiration of two contracts in the second and third quarters of 2023, and a third contract that expired in November 2024. Revenues from the Company’s retail segment increased by $9,003,000 in 2024 compared to 2023 due to higher volumes at the Company’s international Gamma Knife facilities, the Company’s single-unit facility in Puebla, Mexico and the three, recently acquired, radiation therapy facilities in Rhode Island.

LINAC Revenue

The Company acquired the RI Companies on May 7, 2024 and included the financial results from their operations from May 7, 2024, the Closing Date of the transaction, through December 31, 2024. The Company’s stand-alone radiation therapy facility in Puebla, Mexico also began treating patients in July 2024. Radiation therapy revenues generated from the three stand-alone facilities acquired through the RI Acquisition and the radiation therapy facility in Puebla were $8,517,000 for the year ended December 31, 2024. Radiation therapy procedures for the three stand-alone facilities acquired through the RI Acquisition and the radiation therapy facility in Puebla were 14,507 for the year ended December 31, 2024.

Proton Therapy Revenue

Increase

Revenue from PBRT (in thousands) $ 9,952 (1.8 )% $ 10,133

PBRT revenue for 2024 was $9,952,000 compared to $10,133,000 in 2023. The number of PBRT fractions performed in 2024 was 5,139 compared to 5,369 in 2023. Revenue per fraction in 2024 was $1,937 compared to $1,887 in 2023. The Company’s PBRT unit in Orlando, Florida, was impacted by several hurricanes during 2024, which resulted in lower procedure volume. 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.

Gamma Knife Revenue

Increase

Revenue from Gamma Knife (in thousands) $ 9,716 (11.6 )% $ 10,992

Number of Gamma Knife procedures 1,084 (9.3 )% 1,195

Average revenue per procedure $ 8,963 (2.6 )% $ 9,198

Gamma Knife revenue for 2024 was $9,716,000 compared to $10,992,000 in 2023. Gamma Knife revenue for 2024 decreased $1,276,000 compared to 2023 due to the expiration of two contracts in the second and third quarters of 2023, and a third contract that expired in November 2024.

The number of Gamma Knife procedures performed in 2024 decreased by 111 compared to 2023 primarily due to the expiration of two contracts in the second and third quarters of 2023, and a third contract that expired in November 2024. Excluding the three Gamma Knife contracts that expired during 2023 and 2024, Gamma Knife procedures for existing sites were consistent with the prior year. Gamma Knife procedures for existing customer sites, retail segment, increased by 24%, offset by a 15% decrease in the Company’s Gamma Knife leasing segment in 2024 compared to 2023, respectively. The increase in Gamma Knife volumes from retail sites was due to improved marketing and physician outreach at the Company’s international locations. In addition, the Company’s Gamma Knife unit in Ecuador was upgraded to the Esprit and received a Cobalt-60 reload in November 2023, providing for faster procedure time.

Revenue per procedure decreased by $235 in 2024 compared to 2023. This decrease was due to changes in reimbursement at the Company’s revenue share sites, which can fluctuate depending on payor mix and volume of procedures by site.

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 $7,174,000 in 2024 compared to 2023.

Maintenance and supplies and other direct operating costs, related party, as a percentage of total revenue were 10.7% and 13.5% in 2024 and 2023, respectively. Maintenance and supplies and other direct operating costs, related party increased by $138,000 in 2024 compared to 2023. The increase in 2024 compared to 2023was primarily due to maintenance at the Company’s radiation therapy facilities in Rhode Island, that were acquired during 2024, offset by lower maintenance expense for the Company’s Gamma Knife portfolio.

Depreciation and amortization costs as a percentage of total revenue were 21.4% and 23.8% in 2024 and 2023. Depreciation and amortization costs increased $996,000 in 2024 compared to 2023. The increase in 2024 compared to 2023was due to five upgrades performed between 2023 and 2024 where the Company upgraded an existing Gamma Knife to the Esprit, installed a new Esprit, or replaced the Cobalt-60 in the related machines, and the RI Acquisition where the Company acquired three, existing, single-unit radiation therapy facilities.

Other direct operating costs as a percentage of total revenue were 35.5% and 18.9% in 2024 and 2023, respectively. Other direct operating costs increased by $6,040,000 in 2024 compared to 2023. The increase in 2024 was primarily due to the Company’ssingle-unit radiation therapy facility in Puebla, Mexico, which began treating patients in July 2024, and the three single-unit radiation therapy facilities the Company acquired in Rhode Island on May 7, 2024. These facilities are part of the Company’s retail segment where the Company owns and operates the facilities, therefore, there are higher operating costs associated with them.

SELLING AND ADMINISTRATIVE EXPENSE

Increase

Selling and administrative expense $ 7,407 5.5 % $ 7,022

Percentage of total revenue 26.1 % 32.9 %

The Company’s selling and administrative costs increased $385,000 in 2024 compared to 2023. The increase in 2024 was due to increased staffing in the sales, finance and customer retention areas and approximately $560,000 in fees associated with new business opportunities, including those resulting from the RI Acquisition.

INTEREST EXPENSE

Increase

Percentage of total revenue 5.3 % 5.2 %

The Company’s interest expense increased $387,000 in 2024 compared to 2023. The increase for the year ended December 31, 2024 was due to an increase in borrowings, including the Supplemental Term Loan received in January 2024, and the second tranche of the DFC loan received in November 2023.

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

Increase

Loss on write down of impaired assets $ 3,084 228.1 % $ 940

Percentage of total revenue 10.9 % 4.4 %

As of December 31, 2024 and 2023, the Company recognized a loss on the write down of impaired assets of $3,084,000 and $940,000, respectively. During the year ended December 31, 2024, the Company recognized impairment on six of its domestic Gamma Knife units. The Company also increased and impaired its ARO liability for one of the impaired units where the Company does not plan to renew the contract in early 2025 and will remove this unit at its contract term. The six sites that were impaired and ARO for one of the impaired units were recorded as write down of impaired assets for the December 31, 2024.

During the year ended December 31, 2023, the Company recorded an 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.

BARGAIN PURCHASE GAIN RI ACQUISITION

Increase

Bargain purchase gain RI Acquisition, net $ 3,794 * $ —

Percentage of total revenue 13.39 % 0.0 %

The Company recorded a $3,794,000 net bargain purchase gain related to the RI Acquisition that closed on May 7, 2024. The Company acquired 60% of the equity interests of the RI Companies, which operate three radiation therapy facilities, for $2,850,000. The assets acquired exceeded the total purchase price by the bargain purchase amount and the Company recorded this difference as a gain for the year ended December 31, 2024. See Note 12 - RI Acquisition to the consolidated financial statements for further discussion on bargain purchase.

INTEREST AND OTHER INCOME

Increase

Interest and other income (loss) $ 248 (41.2 )% $ 422

Percentage of total revenue 0.9 % 2.0 %

Interest and other income decreased $174,000 in 2024 compared to 2023. The decrease is primarily due to the interest received on the Company’s cash, driven by lower average cash balances, compared to the prior year.

INCOME TAX EXPENSE

Increase

Income tax (benefit) expense $ (295 ) (168.4 )% $ 431

Percentage of total revenue (1.0 )% 2.0 %

Income tax expense decreased $726,000 in 2024 compared to 2023. The decrease in income tax expense in 2024 was primarily due to losses incurred by the Company’s leasing segment, driven by equipment impairment, and lower Gamma Knife volumes during 2024.

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.

NET LOSS ATTRIBUTABLE TO NON-CONTROLLING INTERESTS

Increase

Net loss attributable to non-controlling interests $ (654 ) 89.6 % $ (345 )

Percentage of total revenue (2.3 )% (1.6 )%

Net loss attributable to non-controlling interests increased $309,000 in 2024 compared to 2023. Net income or loss 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, and the 40% non-controlling interests in the RI facilities and their pre-tax income or losses. The decrease or increase in net income attributable to non-controlling interests reflects the relative profitability of GKF and the RI Companies. The increase in net loss attributable to non-controlling interests in 2024 compared to 2023 was due to higher pre-tax loss for GKF stand-alone operations.

NET INCOME ATTRIBUTABLE TO AMERICAN SHARED HOSPITAL SERVICES

(In thousands, Increase

except per share amounts) 2024 (Decrease) 2023

Net income per share attributable to ASHS, diluted $ 0.33 241.8 % $ 0.10

Net income attributable to American Shared Hospital Services increased $1,576,000 in 2024 compared to 2023. Net income for the Company’s retail segment increased $5,474,000 in 2024 compared to 2023. The increase in 2024 compared to 2023 was primarily due to the bargain purchase gain from the RI Acquisition and profitability of the three stand-alone facilities acquired, in which the Company acquired an interest. Net income for the Company’s leasing segment decreased $3,898,000 in 2024 compared to 2023. The decrease in 2024 compared to 2023 was primarily due to the impairment recognized on the Gamma Knife portfolio and related removal costs, along with operating losses at the domestic Gamma Knife leasing segment level.

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 defined above, the “Revolving Line”). The Company had cash and cash equivalents, including restricted cash, of $11,275,000 at December 31, 2024 compared to $13,808,000 at December 31, 2023, a decrease of $2,533,000. The Company’s expected primary cash needs on both a short and long-term basis are for capital expenditures, business expansion, working capital, and other general corporate purposes. The Company believes that its revenue from operations, together with borrowing capacity under the 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 $167,000 of cash in 2024, which was driven by net income of $1,532,000, non-cash charges for depreciation and amortization of $6,174,000, a loss on the write down of impaired assets of $3,084,000, gain on sale of equipment of $155,000, stock-based compensation expense of $373,000, accretion of deferred issuance costs of $95,000, changes in related party liabilities of $324,000, and changes in payables and other accrued liabilities of $2,227,000. These increases were offset by the gain on bargain purchase of $3,794,000, deferred income taxes of $359,000, accretion of unfavorable lease position of $65,000, changes in receivables of $6,939,000, changes in prepaids and other assets of $513,000, changes in ARO of $588,000, and income taxes payable of $1,229,000.

The Company’s trade accounts receivable increased by $7,267,000 to $11,610,000 at December 31, 2024 from $4,343,000 at December 31, 2023. The number of days revenue (sales) outstanding (“DSO”) in accounts receivable as of December 31, 2024 was 150 days compared to 74 days at December 31, 2023. 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. The Company added four retail sites during 2024, driving the increase in DSO.

Cash Flows Used in Investing Activities

Investing activities used $7,105,000 of cash in 2024, primarily due to payments made towards the purchase of property and equipment of $7,938,000, offset by cash received in excess of cash paid for the RI Acquisition of $538,000, and proceeds from equipment sales of $140,000. During 2024, the Company completed two Esprit upgrades at existing customer sites, began installation at a third site, and completed a Cobalt-60 reload and software upgrade at a fourth site.

Cash Flows Provided by Financing Activities

Financing activities provided $4,405,000 of cash during 2024, which was driven by long-term debt financing from the Supplemental Term Loan and Second Supplemental Term Loan of $9,860,000 and capital contributions of $38,000. These increases were offset by net payments on the Revolving Line of $2,500,000, payments on long-term debt of $2,734,000, debt issuance costs of $164,000, and distributions of noncontrolling interests of $95,000. The Company amended its Credit Agreement to include financing for capital expenditures made during 2024 and for the RI Acquisition.

Working Capital

The Company had working capital at December 31, 2024 of $15,853,000 compared to working capital of $9,677,000 at December 31, 2023. The $6,176,000 increase in net working capital was primarily due to an increase in trade, tax, and other receivables, primarily attributable to the RI Companies.

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 facilities have a five-year maturity, carry a floating interest of SOFR plus 3.0% and are secured by a lien on substantially all of the assets of the Loan Parties and guaranteed by ASHS.

On January 25, 2024 (the “First Amendment Effective Date”), the Company and Fifth Third entered into a First Amendment to the Credit Agreement (the “First Amendment”), which amended the Credit Agreement to add a new term loan in the aggregate principal amount of $2,700,000 (the “Supplemental Term Loan”). The proceeds of the Supplemental Term Loan were advanced in a single borrowing on January 25, 2024, and were used for capital expenditures related to the Company’s operations in Puebla, Mexico and other related transaction costs. The Supplemental Term Loan will mature on January 25, 2030 (the “Maturity Date”). 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%.

On December 18, 2024 (the “Second Amendment Effective Date”), the Company and Fifth Third entered into a Second Amendment to the Credit Agreement (the “Second Amendment”), which amended the Credit Agreement to add a new term loan in the aggregate principal amount of $7,000,000 (the “Second Supplemental Term Loan”). The proceeds of the Second Supplemental Term Loan were advanced in a single borrowing on December 18, 2024, and were used for capital expenditures related to the Company’s domestic Gamma Knife leasing operations and the RI Acquisition and related transaction costs. The Second Supplemental Term Loan will mature on December 18, 2029 (the “Second Maturity Date”). Interest on the Second Supplemental Term Loan is payable monthly during the initial twelve month period following the Second 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 Second Supplemental Term Loan over a period of seven years. All unpaid principal of the Second Supplemental Term Loan and accrued and unpaid interest thereon is due and payable in full on the Second Maturity Date. The Second Supplemental Term Loan is secured by a lien on substantially all of the assets of the Company and certain of its domestic subsidiaries.

The long-term debt on the consolidated balance sheets related to the Term Loan, DDTL, Supplemental Term Loan and Second Supplemental Term Loan was

$18,462,000 and

$10,825,000 as of

December 31, 2024 and

December 31, 2023, respectively. The Company capitalized debt issuance costs of

$164,000 as of

December 31, 2024 related to issuance of the Supplemental Term Loan and Second Supplemental Term Loan.

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 Company did not draw on the Revolving Line as of

December 31, 2024.

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), the Company maintain at least $5,000,000 of unrestricted cash, 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, 2024.

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

$1,806,000 and

$2,464,000 as of

December 31, 2024 and 2023, respectively. The Company capitalized debt issuance costs of $0 and $9,000 as of

December 31, 2024 and 2023, 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. On March 3, 2025 the Company received an additional waiver from DFC for certain covenants as of

December 31, 2024 and through December 31, 2025.

In November and December 2024, GKCE obtained two loans with banks locally in Ecuador (the “GKCE Loans”). The GKCE Loans carry interest rates of 12.60% and 12.78% and are payable in twelve and thirty-six equal monthly installments of principal and interest, respectively. Total long-term debt on the consolidated balance sheets related to the GKCE Loans was

$145,000. The Company did not capitalize any debt issuance costs related to the GKCE Loans.

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 $20,182,000 as of December 31, 2024. See Note 5 - Long Term Debt to the consolidated financial statements for additional information.

Commitments

As of December 31, 2024, the Company had commitments to purchase and install Gamma Knife and LINAC equipment totaling $13,053,000. 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 $11,275,000 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 $13,109,000. The Gamma Knife, PBRT, LINAC and related 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, 2024 and 2023, and the related consolidated statements of income, 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, 2024 and 2023, 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. Under revenue sharing arrangements, the Company recognizes revenue based on 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. Under fee per use arrangements, the Company recognizes revenue at the time the procedures are performed, based on each hospital’s contracted rate and number of procedures performed. During the year ended December 31, 2024, the Company recognized $15.6 million in rental revenue from medical equipment leasing.

We identified the auditing of management’s estimates of reimbursement rates to record rental revenue from medical equipment leasing and related accounts receivable under its revenue sharing arrangements as a critical audit matter. The estimates of reimbursement rates involve significant judgment and estimation by management and are subject to adjustments based on the actual reimbursements received. In turn, auditing management’s judgments used in the estimates of reimbursement rates involved a high degree of auditor judgment and subjectivity.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. Our audit procedures related to the matter included the following, among others:

● Testing the process used by management, including evaluating the methods used.

● Testing the reasonableness of significant assumptions used by management by:

o Testing cash receipts subsequent to year end.

Valuation of Facilities in a Business Combination Transaction

As described in Note 12 of the Company’s consolidated financial statements, on May 7, 2024, the Company closed the acquisition of Southern New England Regional Cancer Center and Roger Williams Radiation Therapy, LLC. The acquisition was accounted for as a business combination. The Company recorded the acquired facilities at their estimated fair value. The cost approach was used to estimate the fair value the facilities acquired.

We identified the auditing of the estimated fair value of the facilities with existing leases acquired in the business combination, as a critical audit matter. The estimated fair value of the facilities required significant management judgment. In turn, auditing management’s judgments required a high degree of auditor judgment including the need to involve our valuation specialists.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. Our audit procedures related to the estimated fair value of the acquired facilities included the following, among others:

● Testing the process used by management.

● Testing the underlying data for mathematical accuracy used in the estimate.

Impairment of Property and Equipment

As described in Note 2 to the consolidated financial statements, the Company assesses the recoverability of its long-lived assets when events or changes in circumstances indicate their carrying value may not be recoverable. 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, and measured as the amount by which the carrying amount exceeds estimated fair value. As of December 31, 2024, the Company’s balance of property and equipment was $31.1 million. During the year ended December 31, 2024, the Company recognized impairment losses related to property and equipment of $3.1 million.

We identified the auditing of the Company’s impairment assessment for property and equipment as a critical audit matter. Auditing the Company’s impairment assessment for its property and equipment is especially challenging due to the high degree of auditor judgment in evaluating management’s indicators of potential impairment for certain asset groups and determining the future cash flows and estimated fair values, where applicable, for certain asset groups where indicators of impairment were determined to be present.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements. Our audit procedures related to the matter included the following, among others:

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 2024, GKF leased Gamma Knife units to ten medical centers in the United States in the states of 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.

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 SNERCC and RWRT, (collectively, the “RI Companies”) and to assign certain payor contacts to the Company for a purchase price of $2,850,000 (such transaction, the “RI Acquisition”). The equity interests acquired by the Company under the IPA equates to a 60% interest in each RI Company. The RI Companies operate three functional radiation therapy cancer centers in Rhode Island. The parties closed the RI Acquisition on May 7, 2024. Accordingly, activity from May 7, 2024 forward is included in the consolidated financial statements. See Note 12 - Rhode Island Acquisition to the consolidated financial statements for further information.

On June 28, 2024, ASHS-Mexico, S.A.P.I. de C.V. signed a Joint Venture Agreement with Hospital San Javier, S.A. de C.V.

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, impairment of property and equipment, the obligation to remove this equipment at contract term (ARO), business combinations, and revenue recognition 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 $98,000 and $165,000 during the years ended December 31, 2024 and 2023, 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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

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.

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 its 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 by17 locations or 1 PBRT unit, 4 LINACs and 12 Gamma Knife units in 2024 and by 15 locations or 1 PBRT unit and 14 Gamma Knife units in 2023. Two customers individually accounted for approximately 35% and 27% of the Company’s total revenue in 2024, and one customer accounted for 48% of the Company’s total revenue in 2023, respectively. At December 31, 2024, one location accounted for 32% of total accounts receivable. At December 31, 2023, two locations each individually accounted for 30% and 31% 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 credit losses 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 the RI Companies and in the 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 income.

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 December 31, 2023, the Company had seven domestic Gamma Knife units with salvage value ranging from $140,000 to $300,000. As of December 31, 2024, the Company reduced its estimate of salvage value for all seven Gamma Knife units to $0. This change was made as of December 31, 2024, therefore there was no impact from the change in estimate for the current year, but this change in estimate will impact 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, 2024, the Company held equipment under operating lease contracts with customers with an original cost of $54,266,000 and accumulated depreciation of $37,002,000. 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 $51,976,000.

As of December 31, 2024 and 2023, the Company recognized a loss on the write down of impaired assets of $3,084,000 and $940,000, respectively. The Company reviewed its long-lived assets during the fourth quarter of 2024 and concluded events and circumstances existed that indicated six of the Company’s domestic Gamma Knife units were impaired. One of the assets was partially impaired in the prior year and is now fully impaired, and the Company expects to remove this equipment prior to the contract term. The Company also increased and impaired its asset removal obligation (“ARO”) liability for one of the impaired units where the Company does not plan to renew the contract in early 2025 and will remove this unit at its contract term. The six sites that were impaired and ARO for two of the impaired sites, were recorded as write down of impaired assets for the December 31, 2024. Total ARO impairment for the year ended December 31, 2023 was $450,000. Total equipment impairment for the year ended December 31, 2023 was $2,634,000.

During the year ended December 31, 2023, the Company recorded an 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 revenues 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 typically have a ten-year term and are classified as either fee per use or revenue sharing. Fee per use 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 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 statements of income. For the years ended, December 31, 2024 and 2023, the Company recognized leasing revenue of approximately $15,629,000 and $17,772,000 under ASC 842, respectively, of which approximately $9,952,000 and $10,133,000 were for PBRT services, respectively.

Revenue sharing arrangements amounted to approximately

70% and

67% of total revenue for the years ended

December 31, 2024 and 2023, 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 six and nine months, following issuance of invoice. The Company did not capitalize any incremental costs related to the fulfillment of its customer contracts.

On May 7, 2024, the Company acquired 60% of the equity interests of the RI Companies. The RI Companies operate three, existing, stand-alone radiation therapy cancer centers in Woonsocket, Warwick and Providence, Rhode Island, where contracts exist between the Company’s facilities and the individual patients treated at the facility. Under ASC 606, the Company acts as the principal in these transactions and provides, at a point in time, a single performance obligation, in the form of radiation therapy treatment. The Company’s stand alone radiation therapy facility in Puebla, Mexico is also accounted for under ASC 606. Revenue related to radiation therapy is recognized at the expected amount to be received, based on insurance contracts and payor mix, 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. Payment terms at these facilities are typically prepaid for self-pay patients and insurance providers are paid net 30 to 60 days. The Company did not capitalize any incremental costs related to the fulfillment of its customer contracts. The Company also concluded these facilities are part of its retail segment, see further discussion below.

Accounts receivable under ASC 606 at December 31, 2024 and January 1, 2024 were $11,229,000 and $1,626,000. Accounts receivable under ASC 606 at December 31, 2023 and January 1, 2023 were $1,626,000 and $1,118,000. For the years ended December 31, 2024 and 2023, the Company recognized retail revenues of approximately $12,556,000 and $3,553,000 under ASC 606, respectively.

Equipment sales – During the year-ended December 31, 2024, the Company sold one of its Gamma Knife Perfexion units with an Icon upgrade to the customer it was leased to and recorded a net gain on equipment sale. 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 revenues of $155,000 and $200,000 on the sale of equipment for the years ended December 31, 2024 and 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.

Business Combinations - Business combinations are accounted for under ASC 805Business Combinations (“ASC 805”) using the acquisition method of accounting. Under the acquisition method of accounting, all assets acquired, identifiable intangible assets, liabilities assumed and applicable non-controlling interests are recognized at fair value as of the acquisition date. Costs incurred associated with the acquisition of a business are expensed as incurred. The allocation of purchase price requires management to make significant estimates and assumptions, especially with respect to tangible assets, any intangible assets identified and non-controlling interests. These estimates include, but are not limited to, a market participant’s expectation of future cash flows from acquired customers, acquired trade names, useful lives of acquired assets, and discount rates. See Note 12 - Rhode Island Acquisition to the consolidated financial statements for further discussion on acquisitions.

Fair Values of Financial Instruments - Financial assets and liabilities measured at fair value on a recurring basis are classified in one of the three following categories, which are described below:

Level 1 — Valuations based on unadjusted quoted prices for identical assets in an active market.

Level 2 — Valuations based on quoted prices in markets where trading occurs infrequently or whose values are based on quoted prices of instruments with similar attributes in active markets.

Level 3 — Valuations based on inputs that are unobservable and involve management judgment and our own assumptions about market participants and pricing.

The Company does not have any financial assets or liabilities that are measured at fair value on a recurring basis.

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 its Gamma Knife site in Peru and its startup operations in Mexico for Puebla under ASC 830 as of December 31, 2024 and 2023 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, 2024, the Company had two AROs recorded for the two customer sites that will expire during 2025, totaling $1,200,000. One ARO was recorded and impaired in a prior period. The Company recorded and impaired an ARO for a second customer site during 2024.No liability has been recorded as of December 31, 2024 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.

Asset retirement obligations, included in related party liabilities, were $1,200,000 and $650,000 at December 31, 2024 and 2023, respectively. The following illustrates the change in asset retirement obligations, related party as of December 31, 2024 and 2023:

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.

NOTE 2– ACCOUNTING POLICIES (CONTINUED)

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 type of equipment varies by segment, but the method for recognizing revenue is the same. The operating results of the two reportable segments are reviewed by the Company’s Executive Chairman of the Board, who is also the CODM.
