PERMA-FIX ENVIRONMENTAL SERVICES, INC.

INDEX

PART I

Company Overview and Principal Products and Services

Perma-Fix Environmental Services, Inc. (the Company, which may be referred to as we, us, or our), a Delaware corporation incorporated in December 1990, is an environmental and environmental technology know-how company.

The principal element of our business strategy consists of upgrading our facilities within our Treatment Segment to increase efficiency and modernize and expand treatment capabilities to meet the changing markets associated with the waste management industry. Within our Services Segment, we are attempting to increase competitive procurement effectiveness and broaden the market penetration within both the commercial and government sectors. We continue to increase our focus on expansion into both commercial and international markets (see “Foreign Revenue and Initiatives” below for further discussion of our international initiatives to supplement government spending in the United States of America (“USA”), from which a significant portion of our revenue is derived). This includes new services, new customers and increased market share in our current markets.

We were disappointed with our 2024 financial results, which were negatively impacted by a number of unexpected events and factors. These events and factors included among other things,

Although we are disappointed with our 2024 financial results, we believe our base business is positioned for improvement and we expect that our results of operations should improve in 2025. We continue to advance a number of initiatives that are discussed within this report. Some of these initiatives have been realized, with additional initiatives expected to be more fully realized in 2025. In December 2024, BWXT Technologies, Inc (“BWXT”) announced that the U.S. Department of Energy (“DOE”) had awarded BWXT and its team, of which we are a member, the contract for the cleanup operations at the West Valley Development Project in West Valley, NY. As disclosed by BWXT, the contract has a 10-year ordering period with a maximum value of up to $3 billion that can be performed for up to 15 years. The scope attributable to us has not yet been defined and is subject to certain approvals. The West Valley Project is anticipated to begin transition in the first quarter of 2025 and realize full operations 120 days from initiation. Also, as previously disclosed, in December 2023 we and our Italian team partner were awarded a multi-year contract for the treatment of radioactive waste from the Joint Research Center in Ispra, Italy (see “Foreign Revenue and Initiatives” below for a discussion of this contract and further international initiatives).

Our continuing initiatives include, among other things, positioning ourselves for further large and mid-size procurements within the DOE and U.S. Department of Defense (“DOD”) and waste treatment in support of DOE’s Hanford closure strategy, continued investments in our facilities and capabilities to allow for broader waste treatment (including PFAS) (see “New Processing Technology” below for a discussion of our PFAS technology), and continued expansion of our waste treatment offerings within the international and commercial markets.

Although we expect our financial results to improve in 2025, uncertainties exist regarding how future federal government budget and program and policy decisions will unfold, which include the spending priorities of the new Administration and Congress, passage of the 2025 fiscal year U.S. government budget and potential for enactment of additional continuing resolutions to keep government departments and agencies in operations. A significant amount of our revenues are generated indirectly as subcontractors for others who are contractors to federal government authorities, which include the DOE and DOD, or directly as the prime contractor to federal government authorities. The full impact of these uncertainties could negatively impact our financial results by impairing our ability to perform work on existing contracts, delaying or cancelling procurement actions by government entities, and/or cause other disruptions or delays, including payment delays.

Segment Information

We have two reporting segments:

TREATMENT SEGMENT reporting includes:

For 2024, the Treatment Segment accounted for $34,953,000, or 59.1%, of total revenue, as compared to $43,477,000, or 48.5%, of total revenue for 2023.

SERVICES SEGMENT, which includes:

For 2024, the Services Segment accounted for $24,164,000, or 40.9%, of total revenue, as compared to $46,258,000, or 51.5%, of total revenue for 2023.

Our Treatment and Services Segments provide services primarily to research institutions, commercial companies, public utilities, and governmental entities, including the DOE and DOD. However, we continue to increase our focus on expansion into international markets. The distribution channels for our services are through direct sales to customers or via intermediaries.

Our corporate office is located at 8302 Dunwoody Place, Suite 250, Atlanta, Georgia 30350.

Foreign Revenue and Initiatives

We continue to increase our focus on expansion into international markets. In 2024, we were awarded contracts in support of waste treatment services from Mexico and Canada totaling approximately $6,000,000 (US$). These contracts require specific permits that can include a six to nine-month approval period. As such, receipts of these waste shipments are expected in 2025. We expect additional opportunities forthcoming in Germany in support of existing commercial clients as well as providing support to Germany’s power utility decommissioning program.

As previously disclosed, in December 2023, we and our partner, Campoverde Srl, each owning 50% of the partnership, in connection with an Italian project, were awarded a multi-year contract valued up to approximately EUR 50 million by the European Commission (the “Contracting Authority”) for the treatment of radioactive waste from the Joint Research Center in Ispra, Italy. Revenue generated and to be generated by us from this contract has been and will be limited to project management support through 2025. The scope of work in the initial phases of this contract is being performed predominantly by our partner. We expect to generate an increase in revenue under this contract starting in 2026 when the waste treatment phases begin. The Contracting Authority may terminate the contract under certain conditions as set forth in the contract.

Our consolidated revenue for 2024 and 2023 included approximately $2,452,000, or 4.1%, and $2,066,000, or 2.3%, respectively, from foreign customers.

New Processing Technology

During 2024, we completed the fabrication, installation, commissioning and startup of our first full scale commercial Perma-FAS system (“System”) for PFAS destruction, located at our Perma-Fix Florida, Inc. facility. PFAS, commonly known as “forever chemicals,” is the acronym for Perfluoroalkyl and Polyfluoroalkyl Substances, a diverse group of thousands of humanmade chemical pollutants that have the potential to persist in both the environment and the human body. An increasing number of studies have documented adverse health risks that are associated with PFAS exposure, including increased risks of some cancers, reduced immune function, and developmental delays in children. Commercial destruction of PFAS offers a promising new source of revenue for us, as it complements our core waste remediation technologies, and wee have filed patent applications relating to our System technology for PFAS destruction. With the successful startup of our pilot System, we have already processed commercial quantities of PFAS-containing waste materials. There are limited current treatment options for these materials, and we expect that our process will exceed any of these other current methods. Some of the sizable markets for PFAS include AFFF (aqueous film-forming foam) firefighting foams, both expired concentrate and flushing liquids, contaminated liquids from PFAS systems, and other water-based separation products from a variety of industrial systems. We have already secured and are treating approximately 6,000 gallons of AFFF liquids to support ongoing operations, demonstration, and further testing of our System. We believe that we will receive an additional 20,000 gallons in the coming months.

Our strategy for our System includes continued treatment of PFAS liquids over the coming months and targeting engineering refinements to support larger-scale Systems. With significant upgrades to our prototype currently in the design phase, we anticipate deployment of the second generation unit in the third quarter of 2025 at one of our other existing treatment facilities. By the third quarter of 2025, we expect to advance this technology into pilot-scale applications for soil, biosolids, and filter media, broadening the reach of our System’s PFAS destruction capabilities.

Seasonal Factors of our Business

Our operations are generally subject to seasonal factors. See “Risk Factors – Risks Related to our Business and Operations – Our operations are subject to seasonal factors, which causes our revenues to fluctuate” for a discussion of our seasonal factors.

Permits and Licenses

Waste management service companies are subject to extensive, evolving and increasingly stringent federal, state, and local environmental laws and regulations. Such federal, state and local environmental laws and regulations govern our activities regarding the treatment, storage, processing, disposal and transportation of hazardous, non-hazardous and radioactive wastes, and require us to obtain and maintain permits, licenses and/or approvals in order to conduct our waste activities. We are dependent on our permits and licenses discussed below in order to operate our businesses. Failure to obtain and maintain our permits or approvals would have a material adverse effect on us, our operations, and financial condition. The permits and licenses have terms ranging from one to ten years, and provide that we maintain a reasonable level of compliance, and renew with minimal effort and cost. We believe that these permit and license requirements represent a potential barrier to entry for possible competitors.

PFF, located in Gainesville, Florida, operates its hazardous, mixed and low-level radioactive waste activities under a Resource Conservation and Recovery Act (“RCRA”) Part B permit, Toxic Substances Control Act (“TSCA”) authorization, Restricted RX Drug Distributor-Destruction license, biomedical, and a radioactive materials license issued by the State of Florida. Co-regulated TSCA Polychlorinated Biphenyl (“PCB”) wastes are also managed for PCB under EPA Approval.

DSSI, located in Kingston, Tennessee, conducts mixed and low-level radioactive waste storage and treatment activities under RCRA Part B permits and a radioactive materials license issued by the State of Tennessee Department of Environment and Conservation, Division of radiological health. Co-regulated TSCA PCB wastes are also managed for PCB destruction under EPA Approval.

PFNWR, located in Richland, Washington, operates a low-level radioactive waste processing facility as well as a mixed waste processing facility. Radioactive material processing is authorized under radioactive materials licenses issued by the State of Washington and mixed waste processing is additionally authorized under a RCRA Part B permit. Co-regulated TSCA PCB wastes are also managed for PCB under EPA Approval.

EWOC, located in Oak Ridge, Tennessee, operates a low-level radioactive waste material processing facility. Radioactive material processing is authorized under radioactive material licenses issued by the State of Tennessee Department of Environmental and Conservation, Division of Radiological Health.

The combination of RCRA Part B hazardous waste permits, TSCA authorizations, and radioactive material licenses held by us and our subsidiaries comprising our Treatment Segment are very difficult to obtain for a single facility and make this Segment unique.

We believe that the permitting and licensing requirements, and the cost to obtain such permits, are barriers to the entry of hazardous waste and radioactive and mixed waste activities as presently operated by our waste treatment subsidiaries. If the permit requirements for hazardous waste treatment, storage, and disposal (“TSD”) activities and/or the licensing requirements for the handling of low-level radioactive matters are eliminated or if such licenses or permits were made less rigorous to obtain, we believe we would face greater competition in this segment.

Number of Employees

As of December 31, 2024, we employed approximately 305 employees, of whom 293 are full-time employees and 12 are part-time/temporary employees.

As previously disclosed, the Company entered into a Project Labor Agreement (“PLA”), dated June 21, 2023, with UA Plumbers & Steamfitters Local 598. The goal of this partnership is to supply our PFNWR facility with the organized labor force needed to take on the challenges of providing a supplement treatment alternative to include concrete-like grout for Hanford’s Low Activity Tank Waste if and when the DOE grants a contract to PFNWR to treat the Low Activity Tank Waste. We believe that this supplemental capability would support DOE’s glassifying process provided by the Hanford Vitrification Plant for safe transport and disposal off-site of the Low Activity Tank Waste.

Dependence Upon a Single or Few Customers

Our Treatment and Services Segments have significant relationships with federal government authorities. A significant amount of our revenues from our Treatment and Services Segments are generated indirectly as subcontractors for others who are contractors to federal government authorities, particularly the DOE and DOD, or directly as the prime contractor to federal government authorities. The contracts that we are a party to with others as subcontractors to federal government or directly with the federal government generally provide that the government may terminate the contract at any time for convenience at the government’s option. Our inability to continue under existing contracts that we have with federal government authorities (directly or indirectly as a subcontractor) or significant reductions in the level of federal governmental funding in any given year could have a material adverse impact on our operations and financial condition.

We performed services relating to waste generated by federal government clients, either indirectly for others as a subcontractor to federal government entities or directly as a prime contractor to federal government entities, representing approximately $40,550,000 or 68.6% of our total revenue during 2024, as compared to $68,595,000 or 76.4% of our total revenue during 2023.

Our revenues are project/event based where the completion of one contract with a specific customer may be replaced by another contract with a different customer from year to year.

Competitive Conditions

The Treatment Segment’s largest competitor is EnergySolutions which operates numerous treatment facilities and two treatment/disposal facilities for low level radioactive waste. Waste Control Specialists is also a competitor in the treatment/disposal market of low-level radioactive waste. These two competitors also provide us with options for disposal of our treated nuclear waste. The Treatment Segment treats and disposes of DOE generated waste largely at DOE owned sites. Our Treatment Segment currently solicits business primarily on a North American basis with both government and commercial clients; however, we continue to focus on emerging international markets for additional work.

Our Services Segment is engaged in highly competitive businesses in which a number of our government contracts and some of our commercial contracts are awarded through competitive bidding processes. The extent of such competition varies according to the industries and markets in which our customers operate as well as the geographic areas in which we operate. The degree and type of competition we face is also often influenced by the project specification being bid on and the different specialty skill sets of each bidder for which our Services Segment competes, especially projects subject to the governmental bid process. We also have the ability to directly bid on prime federal government small business procurements (small business set asides). Based on past experience, we believe that large businesses are more willing to team with small businesses in order to be part of these often-substantial procurements. There are a number of qualified small businesses in our market that will provide intense competition that may challenge our ability to maintain strong growth rates and acceptable profit margins. For international business there are additional competitors, many from within the country the work is to be performed, making winning work in foreign countries more challenging. If our Services Segment is unable to meet these competitive challenges, it could lose market share and experience an overall reduction in its profits.

Certain Environmental Expenditures and Potential Environmental Liabilities

Environmental Liabilities

We have three remediation projects, that are currently in progress relating to our Perma-Fix of Dayton, Inc. (“PFD”), Perma-Fix of Memphis, Inc. (“PFM”), and Perma-Fix South Georgia, Inc. (“PFSG”) subsidiaries, which are all included within our discontinued operations. These remediation projects principally entail the removal/remediation of contaminated soil and, in most cases, the remediation of surrounding ground water. These remediation activities are closely reviewed and monitored by the applicable state regulators.

As of December 31, 2024, we had total accrued environmental remediation liabilities of $767,000, a decrease of $78,000 from the December 31, 2023, balance of $845,000. The decrease represents payments for our PFSG remediation project. As of December 31, 2024, $1,000 of the total accrued environmental liabilities was recorded as current.

The nature of our business exposes us to significant cost to comply with governmental environmental laws, rules and regulations and risk of liability for damages. Such potential liability could involve, for example, claims for cleanup costs, personal injury or damage to the environment in cases where we are held responsible for the release of hazardous materials; claims of employees, customers or third parties for personal injury or property damage occurring in the course of our operations; and claims alleging negligence or professional errors or omissions in the planning or performance of our services. In addition, we could be deemed a potentially responsible party (“PRP”) for the costs of required cleanup of properties, which may be contaminated by hazardous substances generated or transported by us to a site we selected, including properties owned or leased by us. We could also be subject to fines and civil penalties in connection with violations of regulatory requirements.

R&D

Innovation and technical know-how by our operations is very important to the success of our business. Our goal is to discover, develop and bring to market innovative ways to process waste that address unmet environmental needs. We conduct research internally, and also through collaborations with other third parties. The majority of our research activities are performed as we receive new and unique waste to treat. Our competitors also devote resources to R&D and many such competitors have greater resources at their disposal than we do. R&D totaled $1,172,000 and $561,000 for 2024 and 2023, respectively. The increase in our R&D expenses was attributable primarily to R&D in connection with developing our new technology in treating PFAS (See “New Processing Technology” above for a discussion of this new technology).

Governmental Regulation

Environmental companies, such as us, and their customers are subject to extensive and evolving environmental laws and regulations by a number of federal, state and local environmental, safety and health agencies, the principal of which being the EPA. These laws and regulations largely contribute to the demand for our services. Although our customers remain responsible by law for their environmental problems, we must also comply with the requirements of those laws applicable to our services. We cannot predict the extent to which our operations may be affected by future enforcement policies as applied to existing laws or by the enactment of new environmental laws and regulations. Moreover, any predictions regarding possible liability are further complicated by the fact that under current environmental laws we could be jointly and severally liable for certain activities of third parties over whom we have little or no control. Although we believe that we are currently in substantial compliance with applicable laws and regulations, we could be subject to fines, penalties or other liabilities or could be adversely affected by existing or subsequently enacted laws or regulations. The principal environmental laws affecting our customers and us are briefly discussed below.

The Resource Conservation and Recovery Act of 1976, as amended (“RCRA”)

RCRA and its associated regulations establish a strict and comprehensive permitting and regulatory program applicable to companies, such as us, that treat, store or dispose of hazardous waste. The EPA has promulgated regulations under RCRA for new and existing treatment, storage and disposal facilities including incinerators, storage and treatment tanks, storage containers, storage and treatment surface impoundments, waste piles and landfills. Every facility that treats, stores or disposes of hazardous waste must obtain a RCRA permit or must obtain interim status from the EPA, or a state agency, which has been authorized by the EPA to administer its program, and must comply with certain operating, financial responsibility and closure requirements.

The Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA,” also referred to as the “Superfund Act”)

CERCLA governs the cleanup of sites at which hazardous substances are located or at which hazardous substances have been released or are threatened to be released into the environment. CERCLA authorizes the EPA to compel responsible parties to clean up sites and provides for punitive damages for noncompliance. CERCLA imposes joint and several liabilities for the costs of clean up and damages to natural resources.

Health and Safety Regulations

The operation of our environmental activities is subject to the requirements of the OSHA and comparable state laws. Regulations promulgated under OSHA by the Department of Labor require employers of persons in the transportation and environmental industries, including independent contractors, to implement hazard communications, work practices and personnel protection programs in order to protect employees from equipment safety hazards and exposure to hazardous chemicals.

Atomic Energy Act

The Atomic Energy Act of 1954 governs the safe handling and use of Source, Special Nuclear and Byproduct materials in the U.S. and its territories. This act authorized the Atomic Energy Commission (now the Nuclear Regulatory Commission “USNRC”) to enter into “Agreements with states to carry out those regulatory functions in those respective states except for Nuclear Power Plants and federal facilities like the VA hospitals and the DOE operations.” The State of Florida Department of Health (with USNRC oversight), Office of Radiation Control, regulates the licensing and radiological program of the PFF facility; the State of Tennessee (with USNRC oversight), Tennessee Division of Radiological Health, regulates licensing and the radiological program of the DSSI facility and the EWOC facility; and the State of Washington (with USNRC oversight) Department of Health, regulates licensing and the radiological operations of the PFNWR facility.

Other Laws

Our activities are subject to other federal environmental protection and similar laws, including, without limitation, the Clean Water Act, the Clean Air Act, the Hazardous Materials Transportation Act and the TSCA. Many states have also adopted laws for the protection of the environment which may affect us, including laws governing the generation, handling, transportation and disposition of hazardous substances and laws governing the investigation and cleanup of, and liability for, contaminated sites. Some of these state provisions are broader and more stringent than existing federal law and regulations. Our failure to conform our services to the requirements of any of these other applicable federal or state laws could subject us to substantial liabilities which could have a material adverse effect on us, our operations and financial condition. In addition to various federal, state and local environmental regulations, our hazardous waste transportation activities are regulated by the U.S. Department of Transportation, the Interstate Commerce Commission and transportation regulatory bodies in the states in which we operate. We cannot predict the extent to which we may be affected by any law or rule that may be enacted or enforced in the future, or any new or different interpretations of existing laws or rules.

The following are certain risk factors that could affect our business, financial performance, and results of operations. These risk factors should be considered in connection with evaluating the forward-looking statements contained in this Form 10-K, as the forward-looking statements are based on current expectations, and actual results and conditions could differ materially from the current expectations. Investing in our securities involves a high degree of risk, and before making an investment decision, you should carefully consider these risk factors as well as other information we include or incorporate by reference in the other reports we file with the Securities and Exchange Commission (the “Commission”).

Risks Relating to our Business and Operations

The failure of Congress to approve appropriations bills in a timely manner for the federal government agencies and departments we support, or the failure of the Administration and Congress to reach an agreement on fiscal issues, could delay and reduce spending, cause us to lose revenue and profit, and affect our cash flow.

On an annual basis, Congress is required to approve appropriations bills that govern spending by each of the federal government agencies and departments we support. When Congress is, or Congress and the Administration are, unable to agree on budget priorities or specifics, and thus unable to pass annual appropriations bills on a timely basis, Congress typically enacts a continuing resolution (“CR”). CRs generally allow federal government agencies and departments to operate at spending levels based on the previous fiscal year. When agencies and departments operate on the basis of a CR, funding we expect to receive from clients for work we are already performing and for new initiatives may be delayed or canceled. Congress and the Administration have from time to time failed to agree on a CR, resulting in temporary shutdowns of non-essential federal government functions and our work on such functions. Failures by Congress and the Administration to enact appropriations bills in a timely manner can force federal government agencies and departments to shut down or to cancel, change, or delay the implementation of existing or new initiatives. Such events may result in the loss of revenue and profit, or the deferral of revenue and profit to later periods. There is also the possibility that Congress will fail to raise the U.S. debt ceiling when necessary which, in addition to resulting in federal government shutdowns, could significantly impact the U.S. and global economy, affecting the discretionary spending decisions of our non-governmental clients and affecting the capital markets and our access to sources of liquidity on terms that are acceptable to us. The delayed funding or shutdown of many parts of the federal government, including agencies, departments, programs, and projects we support, could have a substantial negative effect on our revenue, profit, and cash flows.

Budget compromises that may be needed for future fiscal years may continue to be extraordinarily difficult given the complicated grassroots political environment, a closely divided Congress, an increasing federal deficit and debt load, and a challenged economy.

The budgets of many of our state and local government clients are also subject to similar divisions, risks, and uncertainties as are inherent in the federal budget process.

Government regulation, policy and program decisions under the new Administration could impact our business, affecting our profitability and future growth.

A material amount of our revenues is derived from various federal government contracts or subcontracts. Considerable uncertainties exist regarding how future federal budget and program decisions under the new Administration will unfold. Program and policy decisions that have been implemented or may be implemented could negatively impact our business. These programs and policies include, among other things, a scaled down government workforce. These programs and policies and the transition of employees from the government agencies with which we do business could create delays in waste receipts from federal government clients, project, procurements, and contract awards. Additionally, trade tensions or restrictions on trade, including the tariffs that have been imposed, have resulted and could further result in retaliation by imposing tariffs by other countries. The imposition of these tariffs by the U.S. and other countries could result in disruption in supply chains, increased costs on products that we utilize in our business operations, reduce profitability on waste that we treat for international clients and increased cybersecurity threats, among other things. Shift in decreased priorities in government funding for remediation projects by the new administration may also negatively impact our results of operations and financial conditions.

Failure to maintain our financial assurance coverage that we are required to have in order to operate our permitted treatment, storage and disposal facilities could have a material adverse effect on us.

We maintain finite risk insurance policies and bonding mechanisms which provide financial assurance to the applicable states for our permitted facilities in the event of unforeseen closure of those facilities. We are required to provide and to maintain financial assurance that guarantees to the state that in the event of closure, our permitted facilities will be closed in accordance with the regulations. Although we have not had a problem as of the date of this report in maintaining our financial assurance coverage, in the event that we are unable to obtain or maintain our financial assurance coverage for any reason, this could materially impact our operations and our permits which we are required to have in order to operate our treatment, storage, and disposal facilities.

If we cannot maintain adequate insurance coverage, we will be unable to continue certain operations.

Our business exposes us to various risks, including claims for causing damage to property and injuries to persons that may involve allegations of negligence or professional errors or omissions in the performance of our services. Such claims could be substantial. We believe that our insurance coverage is presently adequate. If we are unable to obtain adequate or required insurance coverage in the future, or if our insurance is not available at affordable rates, we would violate our permit conditions and other requirements of the environmental laws, rules, and regulations under which we operate. Such violations would render us unable to continue certain of our operations. These events would have a material adverse effect on our financial condition.

The inability to maintain existing federal government contracts or win new government contracts over an extended period could have a material adverse effect on our operations and adversely affect our future revenues.

A material amount of our Treatment and Services Segments’ revenues are generated through various federal government contracts or subcontracts. Most of our federal government contracts or our subcontracts granted under federal government contracts are awarded through a regulated competitive bidding process. Some federal government contracts are awarded to multiple competitors, which increase overall competition and pricing pressure and may require us to make sustained post-award efforts to realize revenues under these government contracts. Contracts with, or subcontracts involving, federal government are generally terminable for convenience at any time at the option of the governmental agency. From time to time, we have experienced difficulty in obtaining new federal contracts or subcontracts. If we fail to maintain or replace these relationships, or if a material contract is terminated or renegotiated in a manner that is materially adverse to us, our revenues and future operations could be materially adversely affected.

Our existing and future customers may reduce or halt their spending on hazardous waste and nuclear services with outside vendors, including us.

A variety of factors may cause our existing or future customers to reduce, delay or halt their spending on hazardous waste and nuclear services from outside vendors, including us. These factors include, but are not limited to, the following. We have experienced certain of the below factors from time to time:

These events could result in or cause government clients to terminate or cancel existing contracts involving us to treat, store or dispose of contaminated waste and/or to perform remediation projects, at one or more of government sites. These events also could adversely affect us to the extent that they result in the reduction or elimination of contractual requirements, lower demand for nuclear services, burdensome regulation, disruptions of shipments or production, increased operational costs or difficulties or increased liability for actual or threatened property damage or personal injury.

Economic downturns, reductions in federal government funding or other events beyond our control could have a material negative impact on our businesses.

Demand for our services has been, and we expect that demand will continue to be, subject to significant fluctuations due to a variety of factors beyond our control, including, without limitation, economic conditions, reductions in the budget for spending to remediate federal sites due to numerous reasons including, without limitation, the substantial deficits that the federal government has and is continuing to incur, domestic political environment, and competing demands for federal funds that can pressure various areas. During economic downturns, large budget deficits that the federal government and many states are experiencing, and other events beyond our control, including, but not limited to the impact from public health events (such as COVID-19 or other unforeseen public health event), the ability of private and government entities to spend on waste services, including nuclear services, may decline significantly. Our operations depend, in large part, upon governmental funding (for example, the annual budget of the DOE) or specifically mandated levels for different programs that are important to our business could have a material adverse impact on our business, financial position, results of operations and cash flow.

The loss of one or a few customers could have an adverse effect on us.

One or a few governmental customers or governmental related customers have in the past, and may in the future, account for a significant portion of our revenue in any one year or over a period of several consecutive years. Because customers generally contract with us for specific projects, we may lose, and have in the past lost, these significant customers from year to year as their projects with us are completed. Our inability to replace the business with other similar significant projects could have an adverse effect on our business and results of operations.

We are a holding company and depend, in large part, on receiving funds from our subsidiaries to fund our indebtedness.

Because we are a holding company and operations are conducted through our subsidiaries, our ability to meet our obligations depends, in large part, on the operating performance and cash flows of our subsidiaries.

Our Treatment Segment has limited end disposal sites to utilize to dispose of its waste which could significantly impact our results of operations.

Our Treatment Segment has limited options available for disposal of our nuclear waste. Currently, there are only four commercial disposal sites for our low-level radioactive waste and six commercial disposal sites for our very low-level activity waste we receive from non-governmental sites, allowing us to take advantage of the pricing competition between these sites. If one or more of these commercial disposal sites ceases to accept waste or closes for any reason or refuses to accept the waste of our Treatment Segment, for any reason, we would have limited remaining site to dispose of our nuclear waste. With limited end disposal site to dispose of our waste, we could be subject to significantly increased costs which could negatively impact our results of operations.

Direct and indirect macroeconomic impacts resulting from natural disasters, public health events and/or world conflicts in various regions could continue to and may in the future negatively impact our business and results of operations.

Public health threats and outbreaks such as COVID-19 and natural disasters such as hurricanes and severe weather conditions have previously negatively impacted our results of operations. The direct impacts of these such events resulted in delayed waste shipments and temporary shut-down of projects by certain of our customers, and delays in procurement, contract awards and planning on behalf of our government clients which negatively impacted our revenue. Residual and lingering macroeconomic effects from these such events could again in the future impact supply chain, workforce availability, and/or increased costs which could have a downward effect on our business, financial condition and results of operations. Additionally, world conflicts occurring in various regions may lead to similar macroeconomic effects which could have a downward effect on our business, financial conditions and results of operations. We may attempt to increase our sales prices in order to maintain satisfactory margin; however, competitive pressures in our industry may have the effect of inhibiting our ability to reflect these increased costs in the prices of our services that we provide to our customers and therefore reduce our profitability.

Our operations are subject to seasonal factors, which cause our revenues to fluctuate.

We have historically experienced reduced revenues and losses during the first and fourth quarters of our fiscal years due to a seasonal slowdown in operations from poor weather conditions, overall reduced activities during these periods resulting from holiday periods, and finalization of government budgets during the fourth quarter of each year. During our second and third fiscal quarters there has historically been an increase in revenues and operating profits. If we do not continue to have increased revenues and profitability during the second and third fiscal quarters, this could have a material adverse effect on our results of operations and liquidity.

We are engaged in highly competitive businesses and typically must bid against other competitors to obtain major contracts.

We are engaged in highly competitive business in which most of our government contracts and some of our commercial contracts are awarded through competitive bidding processes. We compete with national, regional firms and some international firms with nuclear and/or hazardous waste services practices, as well as small or local contractors. Some of our competitors have greater financial and other resources than we do, which can give them a competitive advantage. In addition, even if we are qualified to work on a new government contract, we might not be awarded the contract because of existing government policies designed to protect certain types of businesses and under-represented minority contractors. Although we believe we have the ability to certify and bid government contract as a small business, there are a number of qualified small businesses in our market that will provide intense competition. For international business, which we continue to focus on, there are additional competitors, many from within the country the work is to be performed, making winning work in foreign countries more challenging. Competition places downward pressure on our contract prices and profit margins. From time to time, we have not been awarded a contract due to one or more of the above competitive conditions. If we are unable to meet these competitive challenges, resulting in our ability to be awarded contracts, we could lose market share and experience on overall reduction in our profits.

We bear the risk of cost overruns in fixed-price contracts. We may experience reduced profits or, in some cases, losses under these contracts if costs increase above our estimates.

Our revenues may be earned under contracts that are fixed-price or maximum price in nature. A number of contracts in our Services Segment are and have in past, been fixed-price or maximum price contracts. Fixed-price contracts expose us to a number of risks not inherent in cost-reimbursable contracts. Under fixed price and guaranteed maximum-price contracts, contract prices are established in part on cost and scheduling estimates which are based on a number of assumptions, including assumptions about future economic conditions, prices and availability of labor, equipment and materials, and other exigencies. If these estimates prove inaccurate, or if circumstances change such as unanticipated technical problems, difficulties in obtaining permits or approvals, changes in laws or labor conditions, supply chain interruptions, weather delays, cost of raw materials, our suppliers’ or subcontractors’ inability to perform, and/or other events beyond our control, such as the impact of public health events, cost overruns may occur and we could experience reduced profits or, in some cases, a loss for that project. Errors or ambiguities as to contract specifications can also lead to cost-overruns.

Adequate bonding is necessary for us to win certain types of new work and support facility closure requirements.

We are often required to provide performance bonds to customers under certain of our contracts, primarily within our Services Segment. These surety instruments indemnify the customer if we fail to perform our obligations under the contract. If a bond is required for a particular project and we are unable to obtain it due to insufficient liquidity or other reasons, we may not be able to pursue that project. In addition, we provide bonds to support financial assurance in the event of facility closure pursuant to state requirements. We currently have a bonding facility but, the issuance of bonds under that facility is at the surety’s sole discretion. Moreover, due to events that affect the insurance and bonding markets generally, bonding may be more difficult to obtain in the future or may only be available at significant additional cost. There can be no assurance that bonds will continue to be available to us on reasonable terms. Our inability to obtain adequate bonding and, as a result, to bid on new work could have a material adverse effect on our business, financial condition and results of operations.

If we cannot maintain our governmental permits or cannot obtain required permits, we may not be able to continue or expand our operations.

We are a nuclear services and waste management company. Our business is subject to extensive, evolving, and increasingly stringent federal, state, and local environmental laws and regulations. Such federal, state, and local environmental laws and regulations govern our activities regarding the treatment, storage, recycling, disposal, and transportation of hazardous and non-hazardous waste and low-level radioactive waste. We must obtain and maintain permits or licenses to conduct these activities in compliance with such laws and regulations. Failure to obtain and maintain the required permits or licenses would have a material adverse effect on our operations and financial condition. If any of our facilities are unable to maintain currently-held permits or licenses or obtain any additional permits or licenses which may be required to conduct its operations, we may not be able to continue those operations at these facilities, which could have a material adverse effect on us.

Risks Related to Laws and Regulations

As a government contractor, we are subject to extensive government regulation, and our failure to comply with applicable regulations could subject us to penalties that may restrict our ability to conduct our business.

Our governmental contracts or subcontracts relating to DOE and DOD sites are a significant part of our business. Allowable costs under U.S. government contracts are subject to audit by the U.S. government. Although we believe that we have complied with applicable environmental regulations, if these audits result in determinations that costs claimed as reimbursable are not allowed costs or were not allocated in accordance with applicable regulations, we could be required to reimburse the U.S. government for amounts previously received.

Governmental contracts or subcontracts involving governmental facilities are often subject to specific procurement regulations, contract provisions and a variety of other requirements relating to the formation, administration, performance and accounting of these contracts. Many of these contracts include express or implied certifications of compliance with applicable regulations and contractual provisions. If we fail to comply with any regulations, requirements or statutes, our existing governmental contracts or subcontracts involving governmental facilities could be terminated or we could be suspended from government contracting or subcontracting. If one or more of our governmental contracts or subcontracts are terminated for any reason, or if we are suspended or debarred from government work, we could suffer a significant reduction in expected revenues and profits. Furthermore, as a result of our governmental contracts or subcontracts involving governmental facilities, claims for civil or criminal fraud may be brought by the government or violations of these regulations, requirements or statutes.

Changes in environmental regulations and enforcement policies could subject us to additional liability and adversely affect our ability to continue certain operations.

We cannot predict the extent to which our operations may be affected by future governmental enforcement policies as applied to existing environmental laws, by changes to current environmental laws and regulations, or by the enactment of new environmental laws and regulations. Any predictions regarding possible liability under such laws are complicated further by current environmental laws which provide that we could be liable, jointly and severally, for certain activities of third parties over whom we have limited or no control.

Our businesses subject us to substantial potential environmental liability.

Our business of rendering services in connection with management of waste, including certain types of hazardous waste, low-level radioactive waste, and mixed waste (waste containing both hazardous and low-level radioactive waste), subjects us to risks of liability for damages. Such liability could involve, without limitation:

Our operations are subject to numerous environmental laws and regulations. We have in the past, and could in the future, be subject to substantial fines, penalties, and sanctions for violations of environmental laws and substantial expenditures as a responsible party for the cost of remediating any property which may be contaminated by hazardous substances generated by us and disposed at such property or transported by us to a site selected by us, including properties we own or lease.

As our operations expand, we may be subject to increased litigation, which could have a negative impact on our future financial results.

Our operations are highly regulated and we are subject to numerous laws and regulations regarding procedures for waste treatment, storage, recycling, transportation, and disposal activities, all of which may provide the basis for litigation against us. In recent years, the waste treatment industry has experienced a significant increase in so-called “toxic-tort” litigation as those injured by contamination seek to recover for personal injuries or property damage. We believe that, as our operations and activities expand, there will be a similar increase in the potential for litigation alleging that we have violated environmental laws or regulations or are responsible for contamination or pollution caused by our normal operations, negligence or other misconduct, or for accidents, which occur in the course of our business activities. Such litigation, if significant and not adequately insured against, could adversely affect our financial condition and our ability to fund our operations. Protracted litigation would likely cause us to spend significant amounts of our time, effort, and money. This could prevent our management from focusing on our operations and expansion.

If environmental regulation or enforcement is relaxed, the demand for our services could decrease.

The demand for our services is substantially dependent upon the public’s concern with, and the continuation and proliferation of, the laws and regulations governing the treatment, storage, recycling, and disposal of hazardous, non-hazardous, and low-level radioactive waste. A decrease in the level of public concern, the repeal or modification of these laws, or any significant relaxation of regulations relating to the treatment, storage, recycling, and disposal of hazardous waste and low-level radioactive waste could significantly reduce the demand for our services and could have a material adverse effect on our operations and financial condition. We are not aware of any current federal or state government or agency efforts in which a moratorium or limitation has been, or will be, placed upon the creation of new hazardous or radioactive waste regulations that would have a material adverse effect on us; however, no assurance can be made that such a moratorium or limitation will not be implemented in the future.

We and our customers operate in a politically sensitive environment, and the public perception of nuclear power and radioactive materials can affect our customers and us.

We and our customers operate in a politically sensitive environment. Opposition by third parties to particular projects can limit the handling and disposal of radioactive materials. Adverse public reaction to developments in the disposal of radioactive materials, including any high-profile incident involving the discharge of radioactive materials, could directly affect our customers and indirectly affect our business. Adverse public reaction also could lead to increased regulation or outright prohibition, limitations on the activities of our customers, more onerous operating requirements or other conditions that could have a material adverse impact on our customers’ and our business.

The elimination or any modification of the Price-Anderson Acts indemnification authority could have adverse consequences for our business.

The Atomic Energy Act of 1954, as amended, or the AEA, comprehensively regulates the manufacture, use, and storage of radioactive materials. The Price-Anderson Act (“PAA”) supports the nuclear services industry by offering broad indemnification to DOE contractors for liabilities arising out of nuclear incidents at DOE nuclear facilities. That indemnification protects DOE prime contractors, but also similar companies that work under contract or subcontract for a DOE prime contract or transporting radioactive material to or from a site. The indemnification authority of the DOE under the PAA was extended through 2025 by the Energy Policy Act of 2005.

Under certain conditions, the PAA’s indemnification provisions may not apply to our processing of radioactive waste at governmental facilities and may not apply to liabilities that we might incur while performing services as a contractor for the DOE and the nuclear energy industry. If an incident or evacuation is not covered under PAA indemnification, we could be held liable for damages, regardless of fault, which could have an adverse effect on our results of operations and financial condition. If such indemnification authority is not applicable in the future, our business could be adversely affected if the owners and operators of new facilities fail to retain our services in the absence of commercial adequate insurance and indemnification.

Risks Relating to our Financial Performance and Position and Need for Financing

If any of our permits, other intangible assets, and tangible assets becomes impaired, we may be required to record significant charges to earnings.

Under accounting principles generally accepted in the United States (“U.S. GAAP”), we review our intangible and tangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Our permits are tested for impairment at least annually. Factors that may be considered a change in circumstances, indicating that the carrying value of our permit, other intangible assets, and tangible assets may not be recoverable, include a decline in stock price and market capitalization, reduced future cash flow estimates, and slower growth rates in our industry. We may be required, in the future, to record impairment charges in our financial statements, in which any impairment of our permit, other intangible assets and tangible assets is determined. Such impairment charges could negatively impact our results of operations.

Breach of any of the covenants in our credit facility could result in a default, triggering repayment of outstanding debt under the credit facility and the termination of our credit facility.

Our credit facility with our bank contains financial covenants. A breach of any of these covenants could result in a default under our credit facility triggering our lender to immediately require the repayment of all outstanding debt under our credit facility and terminate all commitments to extend further credit. We were not required to perform testing of our fixed charge coverage ratio (“FCCR”) in each of the quarters in 2024 but otherwise met all of our other financial covenant requirements. In the past, we have failed to meet our minimum FCCR requirement in certain instances and in each case, our lender has either waived these instances of non-compliance or provided certain amendments to our FCCR requirements which enabled us to meet our quarterly FCCR requirements. Also, our lender has in the past waived our FCCR testing requirement in certain quarters. If we fail to meet any of our financial covenants going forward, including the minimum quarterly FCCR requirement, and our lender does not waive the non-compliance or revise our covenant requirement so that we are in compliance, our lender could accelerate the payment of our borrowings under our credit facility and terminate our credit facility. In such event, we may not have sufficient liquidity to repay our debt under our credit facility and other indebtedness and/or operate our business.

Inability to maintain the required liquidity under our loan agreement with our lender could adversely affect our operations.

We are required to maintain a certain level of Liquidity (defined as borrowing availability under the revolving credit plus cash in our money market deposit account (“MMDA”) maintained with our lender) under our credit facility. The maximum we can borrow under the revolving part of our credit facility is based on a percentage of the amount of our eligible receivables outstanding at any one time reduced by outstanding standby letters of credit and any borrowing reduction that our lender has or may impose from time to time. As of December 31, 2024, we had no borrowing under the revolving part of our credit facility and our Liquidity, as defined under our credit facility was approximately $33,905,000, which included approximately $28,898,000 cash in our MMDA account primarily from the sales of our Common Stock completed in May 2024 and December 2024. These sales were consummated at a negotiated price. A lack of positive operating results could have material adverse consequences on our ability to operate our business. Our ability to make principal and interest payments, to refinance indebtedness, and borrow under our credit facility will depend on both our and our subsidiaries’ future operating performance and cash flow. Prevailing economic conditions, interest rate levels, and financial, competitive, business, and other factors affect us. Many of these factors are beyond our control.

If our financial and operating activities are limited, it could adversely affect our ability to incur additional debt to fund future needs.

We could, among other things, be:

Any of the foregoing could adversely impact our operating results, financial condition, and liquidity. Our ability to continue our operations depends on our ability to generate profitable operations or complete equity or debt financings to increase our capital. See above risk factor for a discussion as to raising Liquidity in connection with our equity financing.

We may be unable to utilize loss carryforwards in the future.

We have approximately $33,470,000 and $81,775,000 in net operating loss carryforwards for federal and state income tax purposes, respectively and expires in various amounts starting in 2024 if not used against future federal and state income tax liabilities, respectively. All of our federal net operating loss carryforwards were generated after December 31, 2017 and thus do not expire. Our net loss carryforwards are subject to various limitations. Our ability to use the net loss carryforwards depends on whether we are able to generate sufficient income in the future years. Given our recent financial performance, we fully reserved these loss carryforwards in 2024. Further, our net loss carryforwards have not been audited or approved by the Internal Revenue Service.

We sustained substantial losses in 2024 and our inability to become profitable on an annualize basis in the foreseeable future could have a material adverse effect on our operations, credit facility, liquidity and potential growth.

The Company sustained substantial losses in 2024. We believe that our results of operations should substantially improve in 2025. If, however, we fail to become profitable on an annualized basis in the foreseeable future, this could have a material adverse effect on our operations, credit facility, liquidity and potential growth.

Risks Relating to our Common Stock

Issuance of substantial amounts of our common stock, par value $0.001 per share (the “Common Stock”) could depress our stock price or dilute the percentage ownership of our Common Stockholders.

Any sales of substantial amounts of our Common Stock in the public market could cause an adverse effect on the market price of our Common Stock and could impair our ability to raise capital through the sale of additional equity securities. The issuance of our Common Stock will result in the dilution in the percentage equity interest of our stockholders and the dilution in ownership value. During 2024, we raised capital through the sales of our Common Stock in May 2024 (2,051,282 shares) and December 2024 (2,530,000 shares). As of December 31, 2024, we had 18,377,237 shares of Common Stock outstanding. In addition, as of December 31, 2024, we had outstanding options to purchase 1,000,900 shares of our Common Stock at exercise prices ranging from $3.15 to $10.20 per share and warrants to purchase 188,038 shares of our Common Stock at exercise prices of $11.50 and $12.19 per share. Future sales of the shares issuable could also depress the market price of our Common Stock.

We do not intend to pay dividends on our Common Stock in the foreseeable future.

Since our inception, we have not paid cash dividends on our Common Stock, and we do not anticipate paying any cash dividends in the foreseeable future. Our credit facility prohibits us from paying cash dividends on our Common Stock without prior approval from our lender.

The price of our Common Stock may fluctuate significantly, which may make it difficult for our stockholders to resell our Common Stock when a stockholder wants or at prices a stockholder finds attractive.

The price of our Common Stock on the Nasdaq Capital Market constantly fluctuates. We expect that the market price of our Common Stock will continue to fluctuate. This may make it difficult for our stockholders to resell the Common Stock when a stockholder wants or at prices a stockholder finds attractive.

General Risk Factors

Loss of certain key personnel could have a material adverse effect on us.

Our success depends on the contributions of our key management, environmental and engineering personnel. Our future success depends on our ability to retain and expand our staff of qualified personnel, including environmental specialists and technicians, sales personnel, and engineers. Without qualified personnel, we may incur delays in rendering our services or be unable to render certain services. We have in the past lost certain key personnel. We cannot be certain that we will be successful in our efforts to attract and retain qualified personnel as their availability is limited due to the demand for hazardous waste management services and the highly competitive nature of the hazardous waste management industry. We do not maintain key person insurance on any of our employees, officers, or directors.

We may not be successful in winning new business mandates from our government, commercial or international customers.

We must be successful in winning mandates from our government, commercial and international customers to replace revenues from projects that we have completed or that are nearing completion and to increase our revenues. We bid on numerous projects, and a number of the projects we bid on, we are not successful in obtaining. Our business and operating results can be adversely affected by the size and timing of a single material contract.

Our failure to maintain our safety record could have an adverse effect on our business.

Our safety record is critical to our reputation. We have from time to time, experienced incidents which impacted certain safety records. In addition, many of our government and commercial customers require that we maintain certain specified safety record guidelines to be eligible to bid for contracts with these customers. Furthermore, contract terms may provide for automatic termination in the event that our safety record fails to adhere to agreed-upon guidelines during performance of the contract. As a result, our failure to maintain our safety record could have a material adverse effect on our business, financial condition and results of operations.

Systems failures, interruptions or breaches of security and other cybersecurity risks could have an adverse effect on our financial condition and results of operations.

We are subject to certain operational risks to our information systems. Because of efforts on the part of computer hackers and cyberterrorists to breach data security of companies, we face risk associated with potential failures to adequately protect critical corporate, customer and employee data. As part of our business, we develop and retain confidential data about us and our customers, including the U.S. government. We also rely on the services of a variety of vendors to meet our data processing and communications needs.

Despite our implemented security measures and established policies, we cannot be certain that all of our systems are entirely free from vulnerability to attack or other technological difficulties or failures or failures on the part of our employees to follow our established security measures and policies. Information security risks have increased significantly. Our technologies, systems, and networks may become the target of cyber-attacks, computer viruses, malicious code, or information security breaches that could result in the unauthorized release, gathering, monitoring, misuse, loss or destruction of our or our customers’ confidential, proprietary and other information and the disruption of our business operations. A security breach could adversely impact our customer relationships, reputation and operations, result in violations of applicable privacy and other laws and/or financial loss to us or to our customers or to our employees, and similar litigation exposure. While we maintain a system of internal controls and procedures, any breach, attack, or failure as discussed above could have a material adverse impact on our business, financial condition, and results of operations or liquidity.

There is also an increasing attention on the importance of cybersecurity relating to infrastructure. This creates the potential for future developments in regulations relating to cybersecurity that may adversely impact us, our customers and how we offer our services to our customers.

Climate change could negatively impact the Company’s operations and financial condition.

Climate change may present both immediate and long-term risks to the Company and our customers and these risks may increase over time. Climate risks can arise from both physical risks (those risks related to the physical effects of climate change) and transition risks (risks related to governmental regulatory requirements, legal technology, market and reputational changes from a transition to a low carbon economy). Climate change could have a material, adverse effect on environmental companies like ours that are involved in the treatment, disposal and other services related to hazardous waste, radioactive waste and/or mixed (waste that contain both hazardous and radioactive) waste by changing or restricting how we perform our services or what services we can perform or taking action that materially increases our costs to do business in order to regulate or reduce climate change.

Failure to obtain intellectual property protection for our proprietary technologies could negatively affect us.

We believe that it is important that we maintain our proprietary technologies. There can be no assurance that our steps to protect our proprietary technologies will be adequate to prevent misappropriation of these technologies by third parties. Such misappropriation could adversely affect our operations and financial condition. Changes to current environmental laws and regulations also could limit the use of our proprietary technology.

Failure to maintain effective internal control over financial reporting or failure to remediate a material weakness in internal control over financial reporting could have a material adverse effect on our business, operating results, and stock price.

Maintaining effective internal control over financial reporting is necessary for us to produce reliable financial reports and is important in helping to prevent financial fraud. If we are unable to maintain adequate internal controls, our business and operating results could be harmed. We are required to satisfy the requirements of Section 404 of Sarbanes Oxley and the related rules of the Commission, which require, among other things, management to assess annually the effectiveness of our internal control over financial reporting.

In the period ended September 30, 2024, we identified a material weakness related to the precision level required to properly evaluate the need for a valuation allowance on our U.S. deferred tax assets. This material weakness resulted in an income tax valuation adjustment recorded during the quarter. The necessary level of precision was not applied when evaluating the need for a valuation allowance. The error was corrected by us in our condensed consolidated financial statements as of September 30, 2024, and for the three and nine months ended September 30, 2024. The material weakness noted did not result in a material misstatement in our previously issued financial statements, nor in the financial statements included in our Quarterly Report on Form 10-Q for the period ended September 30, 2024. We have remediated this material weakness as of December 31, 2024 (see “Item 9A. – Controls and Procedures” for a discussion of the remediation of this material weakness).

If we are unable to maintain adequate internal control over financial reporting or remediate any material weakness identified, there is a reasonable possibility that a misstatement of our annual or interim financial statements will not be prevented or detected in a timely manner. If we cannot produce reliable financial reports, investors could lose confidence in our reported financial information, the market price of our Common Stock could decline significantly, and our business, financial condition, and reputation could be harmed.

Delaware law, certain of our charter provisions, our stock option plans, outstanding warrants and our Preferred Stock may inhibit a change of control under circumstances that could give you an opportunity to realize a premium over prevailing market prices.

We are a Delaware corporation governed by the Delaware General Corporation Law. In general, Section 203 prohibits a Delaware public corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. As a result of Section 203, potential acquirers may be discouraged from attempting to effect acquisition transactions with us, thereby possibly depriving our security holders of certain opportunities to sell, or otherwise dispose of, such securities at above-market prices pursuant to such transactions. Further, certain of our option plans provide for the immediate acceleration of, and removal of restrictions from, options and other awards under such plans upon a “change of control” (as defined in the respective plans). Such provisions may also have the result of discouraging acquisition of us.

As of December 31, 2024, out of 30,000,000 shares of our Common Stock authorized, we had 18,377,237 shares of Common Stock outstanding and 7,642 shares of treasury stock. In addition, as of December 31, 2024, we had outstanding options to purchase 1,000,900 shares of our Common Stock at exercise prices ranging from $3.15 to $10.20 per share and warrants to purchase 188,038 shares of our Common Stock at exercise prices of $11.50 and $12.19 per share. Assuming the issuance of the Common Stock underlying such options and warrant, as of December 31, 2024, we had available for future issuance 10,426,183 shares of authorized and unissued Common Stock, and 2,000,000 shares of our preferred stock. All of our authorized preferred stock ae available for issuance. Future sales of authorized and unissued shares could be used by our management to make it more difficult for, and thereby discourage, an attempt to acquire control of us.

Not Applicable.

Cybersecurity Risk Management and Strategy

Cybersecurity Governance

Our principal executive office is in Atlanta, Georgia. Our Business Center is located in Oak Ridge, Tennessee. Our Treatment Segment facilities are located in Gainesville, Florida; Kingston, Tennessee; Richland, Washington; and Oak Ridge, Tennessee. All of the properties where these facilities operate on are pledged to our senior lender as collateral for our credit facility with the exception of the property at Oak Ridge, Tennessee, which is held as collateral by another bank. Our Services Segment maintains offices, which are all leased properties. We maintain properties in Valdosta, Georgia and Memphis, Tennessee, which are all non-operational and are included within our discontinued operations.

The Company currently leases properties in the following locations for operations and administrative functions within our Treatment and Services Segments, including our corporate office and Business Center:

We believe that the above facilities currently provide adequate capacity for our operations and that additional facilities are readily available in the regions in which we operate, which could support and supplement our existing facilities.

Our Common Stock is traded on the Nasdaq Capital Market (“Nasdaq”) under the symbol “PESI.” The following table sets forth the high and low market trade prices quoted for the Common Stock during the periods shown. The source of such quotations and information is the NASDAQ online trading history reports.

At March 10, 2025, there were approximately 115 stockholders of record of our Common Stock. The actual number of our stockholders is greater than this number since beneficial owners are owners of shares that are held in “street name” by banks, brokers, and other nominees.

Since our inception, we have not paid any cash dividends on our Common Stock and have no dividend policy. Our Loan Agreement dated May 8, 2020, as amended, prohibits us from paying any cash dividends on our Common Stock without prior approval from our lender. We do not anticipate paying cash dividends on our outstanding Common Stock in the foreseeable future.

No sales of unregistered securities occurred during 2024 except the following:

During the first quarter of 2024, the Company issued 30,000 shares of its Common Stock resulting from the exercise of a warrant for the purchase of up to 30,000 shares of the Company’s Common Stock at an exercise price of $3.51 per share, resulting in proceeds received by the Company of approximately $105,000. See “Warrant” in “Note 6 - Capital Stock, Stock Plans, Warrants, and Stock Based Compensation” in “Part II, Item 8, Financial Statements and Supplementary Data” for further discussion of this warrant exercise.

There were no purchases made by us or on behalf of us or any of our affiliated members of shares of our Common Stock during 2024.

See “Note 6 - Capital Stock, Stock Plans, Warrants, and Stock Based Compensation” in Part II, Item 8, “Financial Statements and Supplementary Data” and “Equity Compensation Plans” in Part III, Item 12, “Security Ownership of Certain Beneficial Owners and Management and Related Stockholders Matter” for securities authorized for issuance under equity compensation plans which are incorporated herein by reference.

Certain statements contained within Item 1 – “Business” and this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (“MD&A”) may be deemed “forward-looking statements” within the meaning of Section 27A of the Act, and Section 21E of the Securities Exchange Act of 1934, as amended (collectively, the “Private Securities Litigation Reform Act of 1995”).

Management’s discussion and analysis is based, among other things, on our audited consolidated financial statements and includes our accounts and the accounts of our wholly-owned subsidiaries.

The following discussion and analysis should be read in conjunction with our consolidated financial statements and the notes thereto included in Item 8 of this report.

Overview

We were disappointed with our 2024 financial results, which were negatively impacted by a number of unexpected events and factors. These events and factors included among other things,

As a result of the aforementioned events and factors, overall revenue decreased by $30,618,000 or 34.1% to $59,117,000 for the twelve-months ended December 31, 2024, from $89,735,000 for the corresponding period of 2023. Treatment Segment revenue decreased by $8,524,000 to $34,953,000 or 19.6% from $43,477,000, and Services Segment revenue decreased by $22,094,000 or 47.8% to $24,164,000 from $46,258,000. Total gross profit for the twelve-months ended December 31, 2024, decreased $16,367,000 or 100.0% due to decreased revenue generated in both segments. Selling, general and administrative (“SG&A”) expenses decreased $484,000 or 3.2% for the twelve-months ended December 31, 2024, as compared to the corresponding period of 2023.

During 2024, we provided a full valuation allowance against our deferred tax assets (see a discussion of this valuation allowance and the impact to our financial statements in “Results of Operations – Income Taxes” below).

In 2024, we completed two public equity raises and sold an aggregate 4,581,282 shares of our Common Stock. See “Liquidity and Capital Resources - Financing Activities” within this MD&A for discussions of these equity raises that occurred in May 2024 and December 2024.

Although we are disappointed with our 2024 financial results, we believe our base business is positioned for improvement and that our results of operations should improve in 2025. We continue to advance a number of initiatives which are discussed within this report on Form 10-K. Some of these initiatives have been realized, with additional initiatives that are expected to be more fully realized in 2025. In December 2024, BWXT Technologies, Inc (“BWXT”) announced that the DOE had awarded BWXT and its team, which we are a member of, the contract for the cleanup operations at the West Valley Development Project in West Valley, NY. As disclosed by BWXT, the contract has a 10-year ordering period with a maximum value of up to $3 billion that can be performed for up to 15 years. The scope attributable to us has not yet been defined and is subject to certain approvals. The West Valley Project is anticipated to begin transition in the first quarter of 2025 and realize full operations in 120 days from initiation. As previously disclosed, in December 2023, we and our partner, Campoverde Srl, each owning 50% of the partnership, were awarded a multi-year contract for the treatment of radioactive waste from the Joint Research Center in Ispra, Italy. Revenue generated and to be generated by us from this contract has been and will be limited to project management support through 2025. The scope of work in the initial phases of this contract is being performed predominantly by our partner. We expect to generate an increase in revenue under this contract starting in 2026 when the waste treatment phases begin.

Our continuing initiatives include, among other things, positioning ourselves for further large and mid-size procurements within the DOE and DOD and waste treatment in support of DOE’s Hanford closure strategy, continued investments in our facilities and capabilities to allow for broader waste treatment (including PFAS) (see “Known Trends and Uncertainties - New Processing Technology” within this MD&A for a discussion of our PFAS technology), and continued expansion of our waste treatment offerings within the international and commercial markets (see “Part I, Item 1 – Business – Foreign Revenue and Initiatives” for a discussion of our foreign revenue and initiatives).

See “Known Trends and Uncertainties – Federal Funding” within this MD&A for a discussion of factors that could impacts our results of operations in 2025.

Business Environment

Our Treatment and Services Segments’ business continues to be heavily dependent on services that we provide to federal governmental clients, primarily as subcontractors for others who are contractors to government entities or directly as the prime contractor. We believe demand for our services will continue to be subject to fluctuations due to a variety of factors beyond our control, including, without limitation, current economic and political conditions, the manner in which the applicable government authority will be required to spend funding to remediate various sites and potential future federal budget issues. In addition, our governmental contracts and subcontracts relating to activities at federal governmental sites in the United States are generally subject to termination for convenience at any time at the government’s option. Significant reductions in the level of governmental funding or specifically mandated levels for different programs that are important to our business could have a material adverse impact on our business, financial position, results of operations, and cash flows.

Results of Operations

The reporting of financial results and pertinent discussions are tailored to our two reportable segments: The Treatment Segment and Services Segment.

Summary - Years Ended December 31, 2024 and 2023

Below are the results of continuing operations for years ended December 31, 2024, and 2023 (amounts in thousands):

Revenue

Consolidated revenues decreased $30,618,000 for the year ended December 31, 2024, compared to the year ended December 31, 2023, as follows:

¹⁾ Includes wastes generated by government clients of $2,898,000 and $2,943,000 for the twelve months ended December 31, 2024, and 2023, respectively.

Treatment Segment revenue decreased by $8,524,000 or 19.6% for the twelve-months ended December 31, 2024, over the same period in 2023. The overall decrease in revenue was primarily due to lower waste volume attributed from the factors as discussed in the “Overview” section above. Overall lower averaged price from waste mix within the Treatment Segment also contributed to the revenue decrease. Services Segment revenue decreased by approximately $22,094,000 or 47.8%. The decrease in revenue in the Services Segment was due to the reasons as discussed in the “Overview” above. Additionally, our Services Segment revenues are project based; as such, the scope, duration, and completion of each project vary.

Cost of Goods Sold

Cost of goods sold decreased $14,251,000 for the year ended December 31, 2024, as compared to the year ended December 31, 2023, as follows:

Cost of goods sold for the Treatment Segment decreased by approximately $538,000 or 1.5%. Treatment Segment’s variable costs decreased by approximately $1,467,000 primarily due to overall lower transportation, disposal, lab and bonus/incentive costs. Treatment Segment’s overall fixed costs increased by approximately $929,000 resulting from the following: salaries and payroll related expenses were higher by $1,717,000 due to higher headcount; regulatory costs were higher by approximately $101,000; depreciation expenses were lower by approximately $626,000 due to fully depreciated AROs that occurred in the third quarter of 2023 in connection with our EWOC facility; maintenance costs were lower by approximately $123,000; general expenses were lower by $111,000 in various categories; and travel expenses were lower by approximately $29,000. Services Segment cost of goods sold decreased $13,713,000 or 37.3% primarily due to lower revenue. The decrease in cost of goods sold was primarily due to overall lower salaries/payroll related, outside services, and travel costs totaling approximately $13,565,000; lower depreciation expenses of approximately $220,000; lower general expenses of $49,000 in various categories; and higher material and supplies expenses of approximately $121,000. Included within cost of goods sold is depreciation and amortization expense of $1,637,000 and $2,484,000 for the twelve months ended December 31, 2024, and 2023, respectively.

Gross Profit

Gross profit for the year ended December 31, 2024, was $16,367,000 lower than 2023 as follows:

Treatment Segment gross profit decreased by $7,986,000 or approximately 116.1% and gross margin decreased to (3.2)% from 15.8% primarily due to lower revenue from lower waste volume, overall lower averaged price from waste mix and the impact of our fixed cost structure. Services Segment gross profit decreased by $8,381,000 or 88.3% primarily due to decreased revenue as discussed in the “Overview” above. The decrease in gross margin from 20.5% to 4.6% was attributed to overall lower margin projects as the two large projects completed in late 2023 were higher margin projects. Our overall Services Segment gross margin is impacted by our current projects which are competitively bid on and will therefore have varying margin structures.

SG&A

SG&A expenses decreased $484,000 for the year ended December 31, 2024, as compared to the corresponding period for 2023 as follows:

Administrative SG&A expenses were lower primarily due to lower incentive expenses of approximately $540,000, which was offset by overall higher expenses of $206,000 in various categories. Administrative SG&A expenses in 2023 included incentives earned in connection with the Company’s management incentive plans (“MIPs”) and other employees’ bonus plans. Such incentives were not earned in 2024. Treatment Segment SG&A expenses were higher primarily due to higher salaries and payroll related expenses of approximately $420,000 which were offset by overall lower travel, outside services and general expenses totaling approximately $379,000. The decrease in Services Segment SG&A was primarily due to lower outside services expenses of approximately $102,000 from fewer consulting and legal matters and lower salaries and payroll related expenses of approximately $249,000. The overall lower SG&A expenses were offset by higher credit loss expenses of approximately $160,000 as a certain account receivable was determined to be uncertain as to collectability as of December 31, 2024. Included in SG&A expenses is depreciation and amortization expense of $126,000 and $84,000 for the twelve months ended December 31, 2024 and 2023, respectively.

R&D

R&D expenses increased by $611,000 for the twelve-months ended December 31, 2024, as compared to the corresponding period of 2023 primarily due to expenses incurred in connection with our new PFAS technology.

Interest Income

Interest income increased by approximately $315,000 for the twelve-months ended December 31, 2024, as compared to the corresponding period of 2023. The increase was primarily due to higher interest income earned from our finite risk sinking fund from higher interest rates that took effect starting in March 2023. Additionally, the increase in interest income resulted from more funds that we maintained in our money market deposit accounts from the two equity raises that were complete in May 2024 and December 2024. The overall increase in interest income from the above was reduced by interest income received in March of 2023 of approximately $60,000 in connection with the Employee Retention Credit refund that we received.

Interest Expense

Interest expense increased by approximately $150,000 for the twelve-months ended December 31, 2024, as compared to the corresponding period of 2023. The increase was attributed primarily to interest incurred on the $2,500,000 term loan dated July 31, 2023, under our credit facility and the promissory note that we entered into on July 24, 2024, for the purchase of our EWOC facility. The higher interest expense was also attributed to more finance leases.

Income Taxes

We record a valuation allowance against our net deferred tax asset to the extent we determine it is more likely than not that such asset will not be realized in the future. We regularly evaluate the probability that our deferred tax assets will be realized and determines whether valuation allowances or adjustments thereto are needed. This determination involves judgement and the use of estimates and assumptions, including expectations of future taxable income and tax planning strategies. We apply judgment to consider the relative impact of negative and positive evidence, and the weight given to negative and positive evidence is commensurate with the extent to which such evidence can be objectively verified. Based on our evaluation of all available positive and negative evidence, and with greater weight placed on the objectively verifiable evidence which primarily included our three-year cumulative losses, we determined that it was more likely than not that our net U.S. deferred tax asset will not be realized. As a result, in 2024, we provided a full valuation allowance against our U.S. federal and state deferred tax assets and recorded an income tax expense in the amount of approximately $8,194,000. We continue to maintain a valuation allowance against foreign tax attributes that may not be realized.

We had income tax expenses of $4,435,000 and $17,000 for continuing operations for the twelve-months ended December 31, 2024 and 2023, respectively. Our effective tax rates were approximately 29.3% and 1.8% for the twelve-month ended December 31, 2024 and 2023, respectively. Our effective tax rate for the twelve-months ended December 31, 2024, was impacted primarily by the income tax expense recorded in the amount of approximately $8,194,000 as we provided for a full valuation allowance against our U.S. federal and state deferred tax assets. Our effective tax rate for the twelve-months ended December 31, 2023, was impacted by non-deductible expenses and state taxes.

Backlog

Our Treatment Segment maintains a backlog of stored waste, which represents waste that has not been processed. The backlog is principally a result of the timing and complexity of the waste being brought into the facilities and the selling price per container. As of December 31, 2024, our Treatment Segment had a backlog of approximately $7,859,000, as compared to approximately $8,702,000 as of December 31, 2023. Additionally, the time it takes to process waste from the time it arrives may increase due to the types and complexities of the waste we are currently receiving. We typically process our backlog during periods of low waste receipts, which historically has been in the first or fourth quarters.

Discontinued Operations and Environmental Contingencies

Our discontinued operations consist of all our subsidiaries included in our Industrial Segment which encompasses subsidiaries divested in 2011 and earlier, as well as three previously closed locations.

Our discontinued operations had no revenue for the twelve-months ended December 31, 2024 and 2023. We incurred net losses of $410,000 (net of tax benefit of $149,000) and $433,000 (net of tax benefit of $117,000) for our discontinued operations for the twelve-months ended December 31, 2024, and 2023, respectively. Net losses for both years were primarily due to costs incurred in connection with management of administrative and regulatory matters related to our remediation projects. We have three environmental remediation projects, all within our discontinued operations, which principally entail the removal/remediation of contaminated soil, and, in most cases, the remediation of surrounding ground water.

Liquidity and Capital Resources

Our cash flow requirements during the twelve-months ended December 31, 2024, were primarily financed by our Liquidity (defined as borrowing availability under the revolving credit plus cash in our MMDA maintained with our lender). Our Liquidity included net proceeds received from the sales of an aggregate 4,581,282 shares of our Common Stock pursuant to certain Securities Purchase and Underwriting Agreements executed in May 2024 and December 2024 (see “Financing Activities” below for a discussion of these offerings, including the planned usage of the proceeds). We believe our cash flow requirements for the next twelve months will consist primarily of general working capital needs, scheduled principal payments on our debt obligations, remediation projects, R&D on our PFAS technology and capital expenditures (which include our PFAS technology) (see “Known Trends and Uncertainties – New Processing Technology” within this MD&A for a discussion of this technology). We plan to fund these requirements from our operations and Liquidity under our Credit Facility. We are continually reviewing operating costs and reviewing the possibility of further reducing operating costs and non-essential expenditures to bring them in line with revenue levels. As of December 31, 2024, we had no outstanding borrowing under our revolving credit and our Liquidity under our Credit Facility was approximately $33,905,000. We believe that our cash flows from operations and our Liquidity should be sufficient to fund our operations for the next twelve months. Although we believe our operations should improve in 2025, if we continue to incur losses such as in 2024, this could cause a reduction in our Liquidity.

The following table reflects the cash flow activity for the year ended December 31, 2024, and the corresponding period of 2023:

As of December 31, 2024, we were in a positive cash position with no revolving credit balance. As of December 31, 2024, we had cash on hand of approximately $28,975,000.

Operating Activities

Cash used in operating activities of our continuing operations during 2024 consisted mostly of the significant net loss that we incurred of approximately $19,569,000, adjusted for certain non-cash items, such as $656,000 of stock-based compensation expense, $1,763,000 of depreciation and amortization expense and the deferred income tax expense of $4,448,000. The decrease in cash used in operating activities of our continuing operations from 2023 to 2024 was driven primarily from the significant net loss that we incurred. Our cash used in operating activities of our discontinued operations consisted primarily of expenses incurred in connection with management and administration of regulatory matters for the Company’s remediation projects.

We had working capital of $28,283,000 (which included working capital of our discontinued operations) as of December 31, 2024, as compared to working capital of $4,613,000 as of December 31, 2023. The improvement in our in our working capital was primarily due to the increase in our cash from the sales of our Common Stock in May 2024 and December 2024, which was offset by the significant losses incurred from our results of operations attributed to the various factors as previously discussed.

Perma-Fix Canada Inc. (“PF Canada”)

Our cash used in operating activities in 2024 included receipt of certain outstanding receivables from Canadian Nuclear Laboratories, LTD (“CNL”) as follows: During the fourth quarter of 2021, PF Canada received a Notice of Termination (“NOT”) from CNL on a Task Order Agreement (“TOA”) that PF Canada entered into with CNL in May 2019 for remediation work within Ontario, Canada (“Agreement”). The NOT was received after work under the TOA was substantially completed and work under the TOA has since been completed. CNL may terminate the TOA at any time for convenience. At year-end 2023, PF Canada had approximately $2,389,000 in outstanding receivables due from CNL as a result of work performed under the TOA. A settlement agreement was reached between PF Canada and CNL on the payment of the aforementioned amount by CNL, subject to certain conditions/terms precedents being met. PF Canada received a partial payment from CNL of the outstanding receivables during the first quarter of 2024. In May 2024, PF Canada received the remaining approximately $1,612,000 in outstanding receivables from CNL. As a result of the aforementioned payments received from CNL, no outstanding receivables remain under the TOA from CNL.

Investing Activities

Cash used in investing activities of our continuing operations during 2024 consisted mostly of our purchases of property and equipment totaling approximately $3,811,000, of which $406,000 was financed. The remaining cash used in investing activities consisted of cash outlays made in connection with our operating permits and certain intangible assets. The increase in cash used in investing activities of our continuing operations in 2024 as compared to 2023 was primarily due to capital expenditures made in connection with our PFAS technology which included the installation of our first unit in treating PFAS. Cash used in investing activities of our discontinued operations was primarily for roof replacement at our PFSG location.

Capital Expenditures

We anticipate making capital expenditures of approximately $2,000,000 to $5,500,000 in 2025 to maintain operations and regulatory compliance requirements and support revenue growth. We expect our capital expenditures to be higher in 2025 based on certain strategic project initiatives which include the installation of our second generation unit for our PFAS technology. We plan to fund our capital expenditures for 2025 from cash from operations, Liquidity under our Credit Facility and/or financing. The initiation and timing of our capital expenditures are subject to a number of factors which include, among other things, cost/benefit analysis, the pace of our strategic project initiatives and improvement in our operations.

Financing Activities

Our cash provided by financing during 2024 consisted mostly of net proceeds of $41,859,000 received from the sales of our Common Stock in May 2024 and December 2024 as discussed below and proceeds received from option and a warrant exercises totaling approximately $292,000, partially offset by principal payments of approximately $832,000 primarily for our Terms Loans and Capital Loan under our Credit Facility (see below for a discussion of our Credit Facility) and $291,000 for our finance leases.

Credit Facility

We entered into a Second Amended and Restated Revolving Credit, Term Loan and Security Agreement, dated May 8, 2020, which has since been amended from time to time, with PNC National Association (“PNC” and “lender”), acting as agent and lender (the “Loan Agreement”). The Loan Agreement provides us with the following credit facility with a maturity date of May 15, 2027 (the “Credit Facility): (a) up to $12,500,000 revolving credit (“revolving credit”), which borrowing capacity is subject to eligible receivables (as defined) and reduced by outstanding standby letters of credit ($3,200,000 as of December 31, 2024) and borrowing reductions that our lender may impose from time to time ($750,000 as of December 31, 2024); (b) a term loan (“Term Loan 1”) of approximately $1,742,000, requiring monthly installments of $35,547 (Term Loan 1 was paid off by us in June 2024); (c) a term loan (“Term Loan 2”) of $2,500,000, requiring monthly installments of $41,667; and (d) a capital expenditure loan (“Capital Loan”) of approximately $524,000, requiring monthly installments of principal of approximately $8,700 plus interest, that commenced on June 1, 2022.

On May 8, 2024 and November 12, 2024, we entered into amendments to our Loan Agreement with our lender which provided the following, among other things:

In connection with the amendments, we paid our lender fees totaling $37,500 which is being amortized over the remaining term of the Loan Agreement as interest expense-financing fees.

On March 11, 2025, we entered into an amendment to our Loan Agreement with our lender which provided the following, among other things:

In connection with the amendment, the Company paid its lender a fee of $12,500.

Our Credit Facility under our Loan Agreement with PNC contains certain financial covenants, along with customary representations and warranties. A breach of any of these financial covenants, unless waived by PNC, could result in a default under our Credit Facility allowing our lender to immediately require the repayment of all outstanding debt under our Credit Facility and terminate all commitments to extend further credit. We were not required to perform testing of our FCCR requirement for the first, second and third quarters of 2024 pursuant to the amendments dated May 8, 2024, and November 12, 2024, to our Loan Agreement as discussed above. We were also not required to perform testing of our FCCR requirement for the fourth quarter of 2024 pursuant to the amendment dated March 11, 2025, to our Loan Agreement, as amended, as discussed above. Otherwise, we met all of our other financial covenant requirements in each of the quarters in 2024. We expect to meet our quarterly financial covenant requirements for the next twelve months.

EWOC Note

Our financing activities for 2024 included monthly principal payments on a note that we entered into on July 24, 2024, to finance the balance of the purchase price of the property where our EWOC facility operates. Pursuant to a Purchase and Sales Agreement dated April 30, 2024, we acquired the property for a purchase price of $425,000, paying $63,750 in cash and financing the balance with a bank loan of $361,250 (the “Note”). The Note, which matures on July 24, 2044 (the “Note”), provides for monthly payments of $3,100 for the first five years commencing August 24, 2024, which payments includes interest at an annual fixed interest rate of 8.10%. Monthly payments under the Note will then be adjusted at the end of years five, ten and fifteen, with interest calculated based on the weekly average five-year US Treasury Securities Rate plus 3.0%. Under no circumstances will the variable interest rate on the Note be less than 4.0% per annum or more than (except in the case of default) the lesser of 20.5% per annum or the maximum rate allowed by applicable law. We agreed to pay the lender 3.0% of the total outstanding principal balance under the Note in the event we pay off our obligations during the first year of the Note. The prepayment penalty rate will be reduced by 1.0% at each subsequent annual anniversary of the Note. No prepayment penalty will apply in the event we pay off the Note on the fourth anniversary of the Note or thereafter. The property was previously accounted for under our operating leases.

Sale of Common Stock (May 2024)

On May 21, 2024, we entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with certain institutional and retail investors (the “Purchasers”), pursuant to which we sold and issued, in a registered direct public offering, an aggregate of 2,051,282 shares of the Company’s Common Stock, at a negotiated purchase price per share of $9.75 (the “Shares”), for aggregate gross proceeds to us of approximately $20,000,000, before deducting fees payable to the placement agents and other estimated offering expenses payable by the Company (the “Offering”). The net proceeds from the Offering was utilized to fund (i) continued R&D and business development relating to our patent-pending process for the destruction of PFAS, as well as the cost of installing at least one commercial treatment unit; (ii) ongoing facility capital expenditures and maintenance costs; and (iii) general corporate and working capital purposes. The Shares were offered and sold by the Company pursuant to the Company’s “shelf” registration statement on Form S-3 and prospectus supplement relating thereto.

Craig-Hallum Capital Group LLC (“Craig-Hallum”) and Wellington Shields & Co. LLC (“Wellington Shields”) (Wellington Shields and Craig-Hallum together are known as the “Placement Agents”) served as the exclusive placement agents in connection with the Offering. We paid the Placement Agents an aggregate cash fee of $1,200,000, which represented 6.00% of the gross proceeds of the Offering. We also reimbursed the Placement Agents certain expenses in connection with the Offering in an aggregate amount of approximately $80,000. As additional compensation to the Placement Agents in connection with the Offering, we also issued to the Placement Agents and two (2) of their designees, warrants (the “Placement Agents’ Warrants”) to purchase an aggregate of 61,538 shares of Common Stock (the “Warrant Shares”), an amount equal to 3.0% of the number of Shares sold in the registered direct offering. The Placement Agents’ Warrants have an exercise price per share equal to $12.19, which is equal to approximately 125% of the price per share of the Shares sold in the Offering. Neither the Placement Agents’ Warrants nor the Warrant Shares have been registered under the Registration Statement or otherwise. The Placement Agents’ Warrants have a term of five years, are exercisable at any time and from time to time, in whole or in part, during the four and one-half (4 ½) year period commencing 180 days from the last date of closing of the Offering, which was May 24, 2024, and are exercisable via “cashless exercise” in certain circumstances. The aggregate fair value of the “Placement Agents’ Warrants” was determined to be approximately $331,000 using the Black-Scholes pricing model with the following assumptions: 58.78% volatility, risk free interest rate of 4.53%, an expected life of five years and no dividend. The aggregate fair market value of the Placement Agent’s Warrants was recorded as an offset to gross proceeds of the Offering and an increase to additional paid-in capital.

After deducting costs incurred (which have all been paid) of approximately $1,544,000 (exclusive of the aggregate fair market value of the Placement Agents’ Warrants as discussed above) which were recorded as a deduction to equity in connection with the Offering, net cash proceeds to us totaled approximately $18,456,000.

Sale of Common Stock (December 2024)

On December 18, 2024, we entered into an underwriting agreement (the “Underwriting Agreement”) with Craig-Hallum Capital Group, LLC (the “Underwriter”) to which we sold and issued pursuant to the terms and conditions of the Underwriting Agreement, 2,200,000 shares of the Company’s Common Stock. The shares of Common stock were sold at a negotiated price to the public of $10.00 per share. The Underwriting Agreement also allowed the Underwriter a 30-day over-allotment option (the “Over-Allotment Option”) to purchase up to an additional 330,000 shares of our Common Stock on the same terms and conditions, which option was exercised in its entirely on December 18, 2024. The shares were offered and sold to the public pursuant to our “universal shelf” registration statement on Form S-3 filed with the Commission on December 2, 2024, and declared effective by the Commission on December 12, 2024, and prospectus supplement relating thereto. The aggregate gross proceeds received by us from the sale of the 2,530,000 shares sold totaled $25,300,000, before deducting fees payable to the Underwriter and other estimated offering expenses payable by us (the “Offering”). The net proceeds from the Offering is anticipated to fund (i) continued R&D and business development relating to our patent-pending process for the destruction of PFAS, as well as the cost of installing at least one second-generation Perma-FAS commercial treatment unit; (ii) ongoing facility capital expenditures and maintenance costs; and (iii) general corporate and working capital purposes.

We paid the Underwriter a total cash fee of 7.00% of the aggregate gross proceeds in the Offering, which totaled approximately $1,771,000. We also reimbursed the Underwriter certain expenses in connection with the Offering in an aggregate amount of approximately $95,000. As additional compensation to the Underwriter in connection with the Offering, we also issued to the Underwriter and three (3) of their designees, warrants (the “Underwriters’ Warrant’s”) to purchase an aggregate of 126,500 shares of Common Stock (the “Warrant Shares”), equal to 5.0% of the number of Shares sold in the offering, at an exercise price per share equal to $11.50, which exercise price is equal to approximately 115% of the price per share of the shares sold in the Offering. The Underwriter’s Warrants have a term of five years, are exercisable at any time and from time to time, in whole or in part, during the five (5) year period commencing on December 19, 2024, the closing date of the Offering, and are exercisable via “cashless exercise” in certain circumstances. The aggregate fair value of the “Underwriter’s Warrants” was determined to be approximately $695,000 using the Black-Scholes pricing model with the following assumptions: 58.51% volatility, risk free interest rate of 4.43%, an expected life of five years and no dividend. The aggregate fair market value of the Underwriter’s Warrants was recorded as an offset to gross proceeds of the Offering and an increase to additional-paid-in capital.

After deducting costs incurred of approximately $2,092,000 (exclusive of the aggregate fair market value of the Underwriter’s Warrants as discussed above) which were recorded as a deduction to equity in connection with the Offering, net cash proceeds to us totaled approximately $23,208,000. We have paid approximately $1,897,000 of the $2,092,000 costs incurred in connection with the Offering.

Off Balance Sheet Arrangements

From time to time, we are required to post standby letters of credit and various bonds to support contractual obligations to customers and other obligations, including facility closures. As of December 31, 2024, the total amount of standby letters of credit outstanding was approximately $3,200,000 and the total amount of bonds outstanding was approximately $20,930,000. We also provide closure and post-closure requirements through a financial assurance policy for certain of our Treatment Segment facilities through American International Group, Inc. (“AIG”). As of December 31, 2024, the closure and post-closure requirements for these facilities were approximately $23,379,000.

Critical Accounting Policies and Estimates

Our consolidated financial statements are prepared based upon the selection and application of US GAAP, which may require us to make estimates, judgments and assumptions that affect amounts reported in our financial statements and accompanying notes. The accounting policies below are those we believe affect the more significant estimates and judgments used in preparation of our financial statements. Our other accounting policies are described in the accompanying notes to our consolidated financial statements of this Form 10-K (see “Item 8 – Financial Statements and Supplementary Data – Notes to Consolidated Financial Statements – Note 2 – Summary of Significant Accounting Policies”):

Revenues. Our revenues are generated from our two reportable segments, Treatment and Services. Certain contracts within our Services Segment are generated from long-term fixed price contracts. Under fixed price contracts, the objective of the project is not attained unless all scope items within the contract are completed and all of the services promised within fixed fee contracts constitute a single performance obligation. Transaction price is determined based on fixed price outline within the contract. Revenue from fixed price contracts is recognized over time primarily using the input method. For the input method, revenue is recognized based on costs incurred on the project relative to the total estimated costs of the project.

Contracts in our Treatment Segment primarily have a single performance obligation as the promise to receive, treat and dispose of waste is not separately identifiable in the contract and, therefore, not distinct. Revenue for Treatment Segment performance obligations are generally satisfied over time using the input method. For the input method, revenue is recognized based on the costs incurred. Transaction price for Treatment Segment contracts are determined by the stated fixed rate per unit price as stipulated in the contract.

Some of our contracts have multiple performance obligations, most commonly when we provide additional services to the customer under a waste treatment contract. For contract with multiple performance obligations, the contract’s transaction price is allocated to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. Generally, we use the observable selling prices from an observable price list, but when a price list is not available, the standalone selling price is determined by the cost plus margin approach.

Within our Treatment Segment, we periodically enter into arrangements with customers for transportation of wastes to either our facility or to non-company owned disposal sites. Revenue from this arrangement is recognized at a point in time, upon the transfer of control. Control transfers when the wastes are picked up by us.

Our contracts generally do not give rise to variable consideration. However, from time to time, we may submit requests for equitable adjustments under certain of our government contracts for price or other modifications that are determined to be variable consideration. We estimate the amount of variable consideration to include in the estimated transaction price based on historical experience with government contracts, anticipated performance and management’s best judgment at the time and to the extent it is probable that a significant reversal of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is resolved. These estimates are re-assessed each reporting period as required.

Intangible Assets. Intangible assets consist primarily of the recognized value of the permits required to operate our business. We continually monitor the propriety of the carrying amount of our permits to determine whether current events and circumstances warrant adjustments to the carrying value.

Indefinite-lived intangible assets are not amortized but are reviewed for impairment annually as of October 1, or when events or changes in the business environment indicate that the carrying value may be impaired. We perform a quantitative test to determine if the fair value of the assets is less than the carrying value. The impairment loss, if any, is measured as the excess of the carrying value of the asset over its fair value. Significant judgments are inherent in these analyses and include assumptions for, among other factors, forecasted revenue, gross margin, growth rate, operating income, timing of expected future cash flows, and the determination of appropriate long-term discount rates.

Impairment testing of our permits related to our Treatment reporting unit as of October 1, 2024, and 2023 resulted in no impairment charges.

Intangible assets that have definite useful lives are amortized using the straight-line method over the estimated useful lives and are excluded from our annual intangible asset valuation review as of October 1. Intangible assets with definite useful lives are tested for impairment whenever events or changes in circumstances indicate that the asset’s carrying value may not be recoverable.

Our future cash flow assumptions and conclusions with respect to asset impairments could be impacted by changes arising from (i) a sustained period of economic and industrial slowdowns (ii) inability to scale our operations and implement cost reduction efforts during reduced demand and/or (iii) a significant decline in our share price for a sustained period of time. These factors, among others, could significantly impact the impairment analysis and may result in future asset impairment charges that, if incurred, could have a material adverse effect on our financial condition and results of operations. We believe that the assumptions and estimates utilized for the reporting periods are appropriate based on the information available to management.

Accrued Closure Costs and Asset Retirement Obligations (“ARO”). Accrued closure costs represent our estimated environmental liability to clean up our facilities as required by our permits, in the event of closure. ASC 410, “Asset Retirement and Environmental Obligations” requires that the discounted fair value of a liability for an ARO be recognized in the period in which it is incurred with the associated ARO capitalized as part of the carrying cost of the asset. The recognition of an ARO requires that management make numerous estimates, assumptions and judgments regarding such factors as estimated probabilities, timing of settlements, material and service costs, current technology, laws and regulations, and credit adjusted risk-free rate to be used. We develop estimates for the cost of these activities based on our evaluation of site-specific facts and circumstances, such as the existence of structures and other improvements that would need to be dismantled and the length of the post-closure period as determined by the applicable regulatory agency, among other things. Included in our cost estimates are our interpretation of current regulatory requirements and any proposed regulatory changes. These cost estimates may change in the future due to various circumstances including, but not limited to, permit modifications, changes in legislation or regulations, technological changes and results of environmental studies. Our cost estimates are calculated using internal sources as well as input from third-party experts. This estimate is inflated, using an inflation rate, to the expected time at which the closure will occur, and then discounted back, using a credit adjusted risk free rate, to the present value. ARO’s are included within buildings as part of property and equipment and are depreciated over the estimated useful life of the property. In periods subsequent to initial measurement of the ARO, we must recognize period-to-period changes in the liability resulting from the passage of time and revisions to either the timing or the amount of the original estimate of undiscounted cash flow. Increases in the ARO liability due to passage of time impact net income as accretion expense and are included in cost of goods sold in the Consolidated Statements of Operations. Changes in the estimated future cash flows costs underlying the obligations (resulting from changes or expansion at the facilities) require adjustment to the ARO liability calculated and are capitalized and charged as depreciation expense, in accordance with our depreciation policy.

Income Taxes. The provision for income tax is determined in accordance with ASC 740, “Income Taxes.” As part of the process of preparing our consolidated financial statements, we are required to estimate our income taxes in each of the jurisdictions in which we operate. We record this amount as a provision or benefit for taxes. This process involves estimating our actual current tax exposure, including assessing the risks associated with tax audits, and assessing temporary differences resulting from different treatment of items for tax and accounting purposes. These differences result in deferred tax assets and liabilities.

We regularly review deferred tax assets by jurisdiction to assess their potential realization and establish a valuation allowance for portions of such assets that we believe will not be realized. In performing this review, we make estimates and assumptions regarding projected future taxable income, the expected timing of the reversals of existing temporary differences and the implementation of tax planning strategies. A change in these assumptions could cause an increase or decrease to the valuation allowance which could materially impact our results of operations.

Recent Accounting Pronouncements

See “Item 8 – Financial Statements and Supplementary Data” – Notes to Consolidated Financial Statements – Note 2 – Summary of Significant Accounting Policies” for the recent accounting pronouncement that was adopted in 2024 and recent accounting pronouncements that will be adopted in future periods.

Known Trends and Uncertainties

Significant Customers. Our Treatment and Services Segments have significant relationships with federal governmental authorities through contracts entered into indirectly as subcontractors for others who are contractors or directly as the prime contractor to federal government authorities. Our inability to continue under existing contracts that we have with the federal government (directly or indirectly as a subcontractor) or significant reductions in the level of governmental funding in any given year could have a material adverse impact on our operations and financial condition.

The contracts that we are a party to with others as subcontractors to the federal government or directly with the federal government generally provide that the government may terminate the contract at any time for convenience at the government’s option. Our inability to continue under existing contracts that we have with the federal government authorities (directly or indirectly as a subcontractor) or significant reductions in the level of governmental funding in any given year could have a material adverse impact on our operations and financial condition. We performed services relating to waste generated by federal government clients, either directly as a prime contractor or indirectly for others as a subcontractor to federal government entities, representing approximately $40,551,000, or 68.6%, of our total revenue during 2024, as compared to $68,595,000 or 76.4%, of our total revenue during 2023.

Federal Funding. As discussed above, a significant portion of our revenue is generated through contracts entered into indirectly as subcontractors for others who are prime contractors or directly as the prime contractor to federal government authorities. Uncertainties exist regarding how future federal government budget and program and policy decisions will unfold, which include, the spending priorities of the new Administration and Congress, passage of the 2025 fiscal year U.S. government budget and potential for enactment of additional continuing resolutions to keep government departments and agencies in operations. The full impact of these uncertainties could negatively impact our financial results by impairing our ability to perform work on existing contracts, delaying or cancelling procurement actions by government entities, and/or cause other disruptions or delays, including payment delays.

New Processing Technology. We have completed the fabrication, installation, commissioning and startup of our first full scale commercial Perma-FAS system (“System”) for PFAS (commonly known as “forever chemicals”) destruction at our Perma-Fix Florida, Inc. facility. Our System and patent-pending technology successfully processed commercial PFAS-containing waste materials. There are limited current treatment options for these materials, and we expect that our process will exceed any of these methods. Some of the sizable markets for PFAS include AFFF (aqueous film-forming foam) firefighting foams, both expired concentrate and flushing liquids, contaminated liquids from PFAS systems, and other water-based separation products from a variety of industrial systems. We have already secured and are treating approximately 6,000 gallons of AFFF liquids to support ongoing operations, demonstration, and further testing of our System. We believe that we will receive an additional 20,000 gallons in the coming months.

Our strategy for our System includes continued treatment of PFAS liquids over the coming months and targeting engineering refinements to support larger-scale Systems. With significant upgrades to our prototype currently in the design phase, we anticipate deployment of the second-generation unit in the third quarter of 2025 at one of our other existing treatment facilities to support revenue generation in the fourth quarter of 2025. By the third quarter of 2025, we expect to advance this technology into pilot-scale applications for soil, biosolids, and filter media, broadening the reach of our System’s destruction capabilities for PFAS.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders

Perma-Fix Environmental Services, Inc.

Opinion on the financial statements

We have audited the accompanying consolidated balance sheets of Perma-Fix Environmental Services, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related consolidated statements of operations, comprehensive (loss) income, stockholders’ 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 financial position of the Company as of December 31, 2024 and 2023, and the 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 audit to obtain reasonable assurance about whether the 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 financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 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 financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical audit matter

The critical audit matter communicated below is a matter arising from the current period audit of the 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 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 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 it relates.

In-Process Fixed Price Service Revenue

As described further in Note 2 to the financial statements, the Company recognizes revenue over time using an input measure of progress for certain fixed priced service arrangements. Under this method, revenue is recorded proportionally based on project costs incurred relative to the estimated total project costs. Auditing the Company’s in-process fixed price arrangements was complex given the judgment required in determining the estimated total project costs. We identified the estimated total project costs for in-process fixed price service arrangements as a critical audit matter.

The principal consideration for our determination that the estimated total project costs for in-process fixed price service arrangements at year-end is a critical audit matter is due to management’s significant judgments when determining such estimated total project costs. Auditing the estimate of total project costs requires a high degree of auditor judgment and increased audit effort due to the judgement involved in management’s estimation of total project costs, which impacts revenue recognition.

Our audit procedures related to the estimated total project costs for in-process fixed price service arrangements included the following, among others.
