Notes to Condensed Consolidated Financial Statements

March 31, 2025

(Unaudited)

Reference is made herein to the notes to consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2024.

1. Basis of Presentation

The condensed consolidated financial statements included herein have been prepared by the Company (which may be referred to as we, us or our), without an audit, pursuant to the rules and regulations of the Securities and Exchange Commission (the “Commission”). Certain information and note disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) have been condensed or omitted pursuant to such rules and regulations, although the Company believes the disclosures which are made are adequate to make the information presented not misleading. Further, the condensed consolidated financial statements reflect, in the opinion of management, all adjustments (which include only normal recurring adjustments) necessary to present fairly the financial position and results of operations as of and for the periods indicated. The results of operations for the three months ended March 31, 2025, are not necessarily indicative of results to be expected for the fiscal year ending December 31, 2025.

These condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K as of and for the year ended December 31, 2024.

The condensed consolidated financial statements include the accounts of our wholly-owned subsidiaries.

2. Summary of Significant Accounting Policies

Our accounting policies are as set forth in the notes to the December 31, 2024, consolidated financial statements referred to above.

Recently Issued Accounting Standards –Adopted

In August 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-05, “Business Combinations—Joint Venture Formations (Subtopic 805-60): Recognition and Initial Measurement.” ASU 2023-05 applies to the formation of a “joint venture” or a “corporate joint venture” and requires a joint venture to initially measure all contributions received upon its formation at fair value. The guidance does not impact accounting by the venturers. The new guidance is applicable to joint venture entities with a formation date on or after January 1, 2025, on a prospective basis. The adoption of ASU 2023-05 by the Company on January 1, 2025, had no impact to its condensed consolidated financial statements.

Recently Issued Accounting Standards – Not Yet Adopted

In November 2024, the FASB issued ASU 2024-03, “Income Statement— Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40) - Disaggregation of Income Statement Expenses,” which enhances the disclosures required for certain expense captions in the Company’s annual and interim consolidated financial statements. ASU 2024-03 is effective prospectively or retrospectively for fiscal years beginning after December 15, 2026, and for interim periods beginning after December 15, 2027. Early adoption is permitted. The Company is currently evaluating the impact of this standard on its disclosures.

7

In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures”, which modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. ASU 2023-09 will become effective starting with the Company’s annual financial statements for the year ended December 31, 2025. The Company is currently evaluating the impact of this standard on its disclosures.

3. Revenue

Disaggregation of Revenue

In general, the Company’s business segmentation is aligned according to the nature and economic characteristics of our services and provides meaningful disaggregation of each business segment’s results of operations. The nature of the Company’s performance obligations within our Treatment and Services Segments results in the recognition of our revenue primarily over time. The following tables present further disaggregation of our revenues by different categories for our Services and Treatment Segments:

Contract Balances

The timing of revenue recognition and billings can result in unbilled receivables (contract assets). The Company’s contract liabilities consist of deferred revenues which represent advance payment from customers in advance of the completion of the Company’s performance obligation. The following table represents changes in our contract asset and contract liabilities balances for the periods noted:

Remaining Performance Obligations

The Company applies the practical expedient in Accounting Standards Codification (“ASC”) 606-10-50-14 and does not disclose information about remaining performance obligations that have original expected durations of one year or less.

Within our Services Segment, there are service contracts which provide that the Company has a right to consideration from a customer in an amount that corresponds directly with the value to the customer of our performance completed to date. For those contracts, the Company has utilized the practical expedient in ASC 606-10-55-18, which allows the Company to recognize revenue in the amount for which we have the right to invoice; accordingly, the Company does not disclose the value of remaining performance obligations for those contracts.

The Company’s contracts and subcontracts relating to activities at governmental sites generally allow for termination for convenience at any time at the government’s option without payment of a substantial penalty. The Company does not disclose remaining performance obligations on these contracts.

4. Leases

At the inception of an arrangement, the Company determines if an arrangement is, or contains, a lease based on facts and circumstances present in that arrangement. Lease classifications, recognition, and measurement are then determined at the lease commencement date.

The Company’s operating lease right-of-use (“ROU”) assets and operating lease liabilities include primarily leases for office and warehouse spaces used to conduct our business. Finance leases primarily consist of lab, processing and transport equipment used by our facilities’ operations.

7. Loss Per Share

Basic loss per share is calculated based on the weighted-average number of outstanding common shares during the applicable period. Diluted loss per share is based on the weighted-average number of outstanding common shares plus the weighted-average number of potential outstanding common shares. In periods where they are anti-dilutive, such amounts are excluded from the calculations of dilutive loss per shares. The following table reconciles the loss and average share amounts used to compute both basic and diluted loss per share:

Credit Facility

The Company entered into a Second Amended and Restated Revolving Credit, Term Loan and Security Agreement, dated May 8, 2020, which has since been amended, with PNC National Association (“PNC” and “lender”), acting as agent and lender (the “Loan Agreement”). The Loan Agreement provides the Company with a credit facility with a maturity date of May 15, 2027 (the “Credit Facility”) which consists of the following as of March 31, 2025: (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 March 31, 2025) and borrowing reductions that the Company’s lender may impose from time to time ($750,000 as of March 31, 2025); (b) a term loan (“Term Loan”) of $2,500,000, requiring monthly installments of $41,667; and (c) a capital expenditure loan (“Capital Loan”) of approximately $524,000, requiring monthly installments of principal of approximately $8,700 plus interest.

Pursuant to the Loan Agreement, payments of annual interest rates are as follows: (i) interest due on the revolving credit is at prime (7.50% at March 31, 2025) plus 2% or Secured Overnight Finance Rate (“SOFR”) (as defined in the Loan Agreement) plus 3.00% plus an SOFR Adjustment applicable for an interest period selected by the Company; (ii) interest due on the Capital Loan is at prime plus 2.50% or SOFR plus 3.50% plus an SOFR Adjustment applicable for an interest period selected by the Company; and (iii) interest due on the Term Loan is at prime plus 3% or SOFR plus 4.00% plus an SOFR Adjustment applicable for an interest period selected by the Company. SOFR Adjustment rates of 0.10% and 0.15% are applicable for a one-month interest period and three-month period, respectively, that may be selected by the Company.

The Company agreed to pay PNC 0.5% of the total financing if the Company pays off its obligations after July 31, 2024, to and including July 31, 2025. No early termination fee shall apply if the Company pays off its obligations under Loan Agreement, as amended, after July 31, 2025.

14

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

| ● | removed the quarterly fixed charge coverage ratio (“FCCR”) covenant testing requirement utilizing a twelve-month trailing basis; however, such FCCR testing requirement will be triggered on the day the Company fails to meet a minimum of $5,000,000 in daily Liquidity (defined under the Loan Agreement as borrowing availability under the revolving credit plus cash in the money market deposit account (“MMDA”) maintained with the Company’s lender). If triggered, the Company will be required to show compliance of a FCCR ratio of not less than 1.15 to 1.00 utilizing a trailing twelve-month-period ended starting with the most recently reported fiscal quarter and each fiscal quarter thereafter. The FCCR testing requirement can be removed again once the Company is able to achieve a minimum of $5,000,000 in daily Liquidity for a thirty-consecutive-day period from the trigger date;
| ● | revised the Facility Fee (as defined) from .375% to .500%. Such fee percentage will revert back to .375% at such time that the Company is able to achieve a minimum 1.15 to 1.00 ratio in FCCR on a twelve-month trailing basis; and
| ● | required payment of an amendment fee of $12,500, by the Company which is being amortized over the remaining term of the Loan Agreement as interest expense-financing fees.

As of March 31, 2025, the Company had no outstanding borrowing under its revolving credit and its Liquidity was approximately $29,277,000.

The Company’s Loan Agreement, as amended, with PNC contains certain financial covenant requirements, along with customary representations and warranties. A breach of any of these financial covenant requirements, unless waived by PNC, could result in a default under the Company’s Loan Agreement allowing its lender to immediately require the repayment of all outstanding debt under the Company’s Loan Agreement and terminate all commitments to extend further credit. The Company met all of its financial covenant requirements in the first quarter of 2025.

9. Commitments and Contingencies

Hazardous Waste

In connection with our waste management services, the Company processes hazardous, non-hazardous, low-level radioactive and mixed (containing both hazardous and low-level radioactive) waste, which we transport to our own, or other, facilities for destruction or disposal. As a result of disposing of hazardous substances, in the event any cleanup is required at the disposal site, the Company could be a potentially responsible party for the costs of the cleanup notwithstanding any absence of fault on our part.

Legal Matters

In the normal course of conducting our business, the Company may be involved in various litigation. The Company is not a party to any litigation or governmental proceeding which our management believes could result in any judgments or fines against us that would have a material adverse effect on our financial position, liquidity or results of future operations.

Tetra Tech EC, Inc. (“Tetra Tech”)

During July 2020, Tetra Tech EC, Inc. (“Tetra Tech”) filed a complaint in the U.S. District Court for the Northern District of California (the “Court”) against CH2M Hill, Inc. (“CH2M”) and four subcontractors of CH2M, including the Company (“Defendants”). The complaint alleges various claims, including a claim for negligence, negligent misrepresentation, equitable indemnification and related business claims against all Defendants related to alleged damages suffered by Tetra Tech in respect of certain draft reports prepared by Defendants at the request of the U.S. Navy as part of an investigation and review of certain whistleblower complaints about Tetra Tech’s environmental restoration at the Hunter’s Point Naval Shipyard in San Francisco.

CH2M was hired by the Navy in 2016 to review Tetra Tech’s work. CH2M subcontracted with environmental consulting and cleanup firms Battelle Memorial Institute, Cabrera Services, Inc., SC&A, Inc. and the Company to assist with the review, according to the complaint.

15

The Company’s insurance carrier provided a defense on our behalf in connection with this lawsuit, subject to a $100,000 self-insured retention and the terms and limitations contained in the insurance policy.

The majority of Tetra Tech’s claims were previously dismissed by the Court. The remaining claims of intentional interference with contractual relations and inducing a breach of contract were dismissed by the Court pursuant to Defendants’ request for summary judgment. Tetra Tech appealed the dismissal of the remaining two claims and subsequently agreed to withdraw its appeal, which the Court dismissed at Tetra Tech’s request. As of March 31, 2025, the litigation has been resolved, and Tetra Tech has formally released and forever discharged the Company from any and all claims arising out of or in any way related to the complaint.

Michael O’Neill

On November 25, 2024, purported shareholder Michael O’Neill filed a complaint in the Court of Chancery of the State of Delaware against the Company and all current directors of the Company, asserting individual and class action claims for alleged breach of contract and breach of fiduciary duty. The case is styled Michael O’Neill v. Perma-Fix Environmental Services, Inc., et al., C.A. No. 2024-1211-PAF.

The complaint purports to be brought by the named plaintiff individually and on behalf of all “similarly situated Perma-Fix stockholders.” According to the complaint, defendants allegedly made materially false and misleading statements in its proxy statement filed with the Securities and Exchange Commission on June 8, 2023 regarding the effect of broker non-votes. In particular, the complaint alleges that defendants incorrectly stated in the proxy statement that broker non-votes would have no effect on the vote solicited to approve an amendment to the Company’s 2017 Stock Option Plan to increase by 600,000 shares the number of shares of Common Stock issuable under the plan, resulting in an alleged defective approval of the plan amendment. As of the date of this Form 10-Q, the Company has not issued any options under the plan relating to the additional shares included in the plan amendment.

The Company believes that the complaint is without merit. The Company and the individual defendants are vigorously defending against the complaint.

The Company’s insurance carrier is providing a defense in connection with this lawsuit, subject to a $1,000,000 self-insured retention and the terms and limitations contained in the insurance policy.

Shareholder Demand Letter

The Company’s Board received a demand letter, dated February 4, 2025 (the “Letter”), from a putative shareholder of the Company, claiming that a provision in the Company’s Amended and Restated Bylaws (“Bylaws”), requiring shareholders, to the fullest extent permitted by law, to indemnify the Company for attorneys’ fees in certain corporate proceedings in which the shareholder is not the prevailing party, must be removed. This provision of the Company’s Bylaws was adopted in 2012 when the Company adopted its Amended and Restated Bylaws. The statute prohibiting certain reimbursements of attorneys’ fees was adopted in 2015. The Letter demands that the Board amend its Bylaws to remove the particular provision in question.

After reviewing the Letter, the Board established a Demand Review Committee (the “Committee”) to review, analyze and evaluate the shareholder demand received above, and to make recommendations to the Board with respect to such demand. The Committee was ad hoc, in that the composition of the Committee will necessarily change in response to the specific shareholder demand. Initial members of the Committee are comprised of Board members who are disinterested and independent with respect to the matters set forth in the Letter discussed above. The Committee was authorized to engage, at the Company’s expense, experts and advisors that the Committee deems appropriate to assist in its review and determination. Based on the Committee’s review and analysis of the demand and the current case law, in connection with the above Letter, the Committee determined to recommend to the Board to reject such demand as being baseless. Based on the Committee’s recommendation to the Board, the Board determined that the demand is meritless and rejected such demand.

Insurance

The Company has a 25-year finite risk insurance policy entered into in June 2003 (“2003 Closure Policy”) with AIG Specialty Insurance Company (“AIG”), which provides financial assurance to the applicable states for our permitted facilities in the event of unforeseen closure. The 2003 Closure Policy, as amended, provides for a maximum allowable coverage of $28,177,000 which includes available capacity to allow for annual inflation and other performance and surety bond requirements. Total coverage under the 2003 Closure Policy, as amended, was $23,949,000 as of March 31, 2025. As of March 31, 2025, and December 31, 2024, finite risk sinking funds contributed by the Company related to the 2003 Closure Policy which is included in other long term assets on the accompanying Condensed Consolidated Balance Sheets totaled $12,824,000 and $12,680,000, respectively, which included interest earned of $3,353,000 and $3,209,000 on the finite risk sinking funds as of March 31, 2025, and December 31, 2024, respectively. Interest income for the three months ended March 31, 2025, and 2024, was approximately $144,000 and $148,000, respectively. If the Company so elects, AIG is obligated to pay the Company an amount equal to 100% of the finite risk sinking fund account balance in return for complete release of liability from both the Company and any applicable regulatory agency using this policy as an instrument to comply with financial assurance requirements.

Letter of Credits and Bonding Requirements

From time to time, the Company is required to post standby letters of credit and various bonds to support contractual obligations to customers and other obligations, including facility closures. As of March 31, 2025, the total amount of standby letters of credit outstanding was approximately $3,200,000, and the total amount of bonds outstanding was approximately $21,481,000.

10. Discontinued Operations

The Company’s discontinued operations consist of all our subsidiaries included in our previous Industrial Segment which encompasses subsidiaries divested in 2011 and prior and three previously closed locations.

The Company’s discontinued operations had net losses of $73,000 (net of taxes of $0) and $102,000 (net of tax benefit of $29,000) for the three months ended March 31, 2025, and 2024. The losses were primarily due to costs incurred in the administration and continued monitoring of our discontinued operations. The Company’s discontinued operations had no revenues for each of the periods noted above.

The following table presents the major class of assets of discontinued operations as of March 31, 2025, and December 31, 2024. No assets and liabilities were held for sale at each of the periods noted.

11. Segment Reporting

In accordance with ASC 280, “Segment Reporting”, the Company defines an operating segment as a business activity: (1) from which we may earn revenue and incur expenses; (2) whose operating results are regularly reviewed by the Chief Operating Decision Maker (“CODM”) to make decisions about resources to be allocated to the segment and assess its performance; and (3) for which discrete financial information is available.

The Company has two reporting segments, consisting of the Treatment and Services Segments, which are primarily based on a service offering approach and defined as follow:

TREATMENT SEGMENT, which includes:

| - | nuclear, low-level radioactive, mixed waste (containing both hazardous and low-level radioactive constituents), hazardous and non-hazardous waste treatment, processing and disposal services primarily through four uniquely licensed and permitted treatment and storage facilities; and
| - | R&D activities to identify, develop and implement innovative waste processing techniques for problematic waste streams.

SERVICES SEGMENT, which includes:

| - | Technical services, which include:

| o | professional radiological measurement and site survey of large government and commercial installations using advanced methods, technology and engineering;
| o | integrated Occupational Safety and Health services including industrial hygiene (“IH”) assessments; hazardous materials surveys, e.g., exposure monitoring; lead and asbestos management/abatement oversight; indoor air quality evaluations; health risk and exposure assessments; health & safety plan/program development, compliance auditing and training services; and Occupational Safety and Health Administration (“OSHA”) citation assistance;
| o | global technical services providing consulting, engineering, project management, waste management, environmental, and decontamination and decommissioning (“D&D”) field, technical, and management personnel and services to commercial and government customers; and
| o | on-site waste management services to commercial and governmental customers.

18

| - | Nuclear services, which include:

| o | technology-based services including engineering, D&D, specialty services and construction, logistics, transportation, processing and disposal;
| o | remediation of nuclear licensed and federal facilities and the remediation cleanup of nuclear legacy sites. Such services capability includes: project investigation; radiological engineering; partial and total plant D&D; facility decontamination, dismantling, demolition, and planning; site restoration; logistics; transportation; and emergency response; and

| - | A company owned equipment calibration and maintenance laboratory that services, maintains, calibrates, and sources (i.e., rental) health physics, IH and customized nuclear, environmental, and occupational safety and health (“NEOSH”) instrumentation.

The Company’s reporting segments exclude our corporate headquarter which serves to support its two reporting segments through various functions, such as our executives, finance, treasury, human resources, accounting, and legal departments. Financial results for the corporate headquarter are not considered by the CODM in evaluating the performance of the reportable segments. Our reporting segment also excludes our discontinued operations (see “Note 10 – Discontinued Operations”) which do not generate revenues.

The Company’s CODM, which is its chief executive officer, evaluates the performance of the Treatment and Services segments and allocates resources (including financial or capital resources) to each reporting segment based on revenue and (loss) income from operations by comparing actual results for these metrics to budgeted and forecasted amounts for these metrics on a monthly, quarterly and year-to-date basis. The Company’s CODM does not evaluate and allocate resources for the reportable segments using assets; therefore, the Company does not disclosure assets for its reporting segments.

The table below summarizes loss from operations for the Company’s two reporting segments and its corporate headquarter and provides reconciliation of such financial metric to the Company’s consolidated totals for the three months ended March 31, 2025, and 2024 for our continuing operations. Significant segment expenses that are included in the measure of segment profit or losses for each reportable segment, and regularly provided to the CODM include payroll and benefit, material and supplies, disposal, transportation and subcontract expenses and are reflected separately, where applicable (in thousands).

12. Income Taxes

The Company uses an estimated annual effective tax rate, which is based on expected annual income, statutory tax rates and tax planning opportunities available in the various jurisdictions in which the Company operates, to determine its quarterly provision for income taxes.

The Company had income tax expense of $0 and income tax benefit of approximately $956,000 for continuing operations for the three months ended March 31, 2025, and 2024, respectively. The Company’s effective tax rate was approximately 0% and 21.7% for the three months ended March 31, 2025, and 2024, respectively. The Company’s effective tax rate for the three months ended March 31, 2025, was impacted by the Company’s recognition of a full valuation allowance against its U.S federal and state deferred tax assets in the quarter ended September 30, 2024. The Company’s effective tax rate for the three months ended March 31, 2024, was impacted by non-deductible expenses and state taxes.

13. Executive Compensation

Appointment of COO

On January 23, 2025, the Company’s Board approved the appointment of Mr. Troy Eshleman as the Company’s COO at an annual salary of $320,000. Mr. Troy Eshleman was originally hired by the Company on January 6, 2025, as Vice President of Operations.

Prior to his appointment to such office, Mr. Grondin previously served as the Company’s EVP of Waste Treatment Operations. Mr. Grondin remains a named executive officer of the Company.

Management Incentive Plans (“MIPs”)

Each MIP is effective January 1, 2025, and applicable for year 2025. Each MIP provides guidelines for the calculation of annual cash incentive-based compensation, subject to Compensation Committee oversight and modification. The performance compensation under each of the MIPs is based upon meeting certain of the Company’s separate target objectives during 2025. The total potential target performance compensation payable ranges from 25% to 150% of the 2025 base salary for the Chief Executive Officer (the “CEO”) ($104,287 to $625,733), 29% to 100% of the 2025 base salary for the Chief Financial Officer (the “CFO”) ($95,681 to $332,811), 29% to 100% of the 2025 base salary for the EVP of Strategic Initiatives ($79,736 to $277,346), 25% to 100% ($78,817 to $315,267) of the 2025 base salary for the EVP of Hanford and International Waste Operations, and 25% to 100% of the 2025 base salary for the COO ($80,000 to $320,000).

Although we believe the expectations reflected in these statements are reasonable, we cannot guarantee future results, levels of activity, performance, or achievements. You should not place undue reliance on the forward-looking statements as noted above, which apply only to as of the date of this Form 10-Q. We undertake no obligation to update these forward-looking statements, even if our situation changes in the future.

Overview

We were disappointed with our overall financial result for the first quarter of 2025 which were impacted by a number of factors which included the following, among other things:

| ● | usual seasonal slowdown in overall operations by customers due to winter weather and holiday returns which contributed to project and waste shipment delays;

23

| ● | delays in procurements and large waste shipments from certain customers due to temporary suspension mandates as directed by the new Administration transition team;
| ● | implementation of operational readiness to support receipts of a certain specific waste stream that are expected to continue for at least the remainder of 2025. The processing of this waste stream required hiring of additional staff, associated training and start-up costs. In late March, we began to accelerate processing of this waste stream backlog; and
| ● | continued aggressive approach to development of our PFAS (Per- and polyfluoroalkyl) technology which included increased spending in research and development (“R&D”), sales and marketing and capital expenditures.

The majority of these factors had limited duration effects as we began seeing improvement in waste receipts starting in the latter part of the first quarter of 2025 which is reflected in our strengthened waste backlog of approximately $10,237,000 as of March 31, 2025, an increase of approximately $2,378,000 or approximately 30.3%, from $7,859,000 as of December 31, 2024. We have also begun to see improvements in procurement actions within the government arena. We believe the continuing increase in waste receipts, combined with improving project visibility, should position us for a return to growth in the remainder of 2025.

In December 2024, BWXT Technologies and its team, of which we are a member, were awarded the West Valley Project contract for the cleanup operations at the West Valley Development Project in West Valley, New York. 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. We expect revenue contribution from this project in the second half of 2025 as our scope under the contract is further defined, approved and transitions into operation. Additionally, we are optimistic that the Direct-Feed Low-Activity Waste (“DFLAW”) program at Hanford, Washington remains on track to begin initial tank waste treatment operations in the third quarter of 2025 which our Perma-Fix Northwest, Richland facility is well-positioned to support. We continue to focus on increasing our expansion into the international markets.

We are continually monitoring our operating costs in order to align with our revenue level.

See “Federal Funding” and “Market Trends and Uncertainties” in “Known Trends and Uncertainties” within this MD&A for a discussion of factors that could negatively impact our results of operations for the remainder of 2025.

Revenue for the first quarter of 2025 increased by approximately $302,000 or approximately 2.2% to $13,919,000 for the first quarter of 2025 from $13,617,000 for the first quarter of 2024. The increase was attributed entirely to our Treatment Segment where revenue increased to $9,186,000 for the first quarter of 2025 from $8,709,000 for the first quarter of 2024, an increase of approximately $477,000 or 5.5%. Services Segment revenue decreased by approximately $175,000 or 3.6% to $4,733,000 for the first quarter of 2025 from $4,908,000 for the first quarter of 2024. Overall gross profit increased by approximately $1,277,000 or 206.0% for the first quarter of 2025 as compared to the corresponding period of 2024. Selling, General, and Administrative (“SG&A”) expenses increased by $471,000 or 13.3% for the three months ended March 31, 2025, as compared to the corresponding period of 2024 (see below “Results of Operations” for further discussions of our financial results).

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 the potential impact from the Continuing Resolution enacted by Congress through the next fiscal federal government budget. In addition, our governmental contracts and subcontracts relating to activities at federal governmental sites 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.

Revenues

Consolidated revenues increased $302,000 for the three months ended March 31, 2025, compared to the three months ended March 31, 2024, as follows:

(In thousands) |  | 2025 |  |  | % Revenue |  |  | 2024 |  |  | % Revenue |  |  | Change |  |  | % Change |

(1) Includes wastes generated by government clients of $440,000 and $628,000 for the three months ended March 31, 2025, and the corresponding period of 2024, respectively.

Treatment Segment revenue increased by $477,000 or 5.5% for the three months ended March 31, 2025, over the same period in 2024. The overall increase in revenue generated from government clients was primarily due to higher waste volume, partially offset by lower averaged price from waste mix. Revenue generated from government clients included approximately $2,207,000 in revenue generated from foreign waste receipts as the Company remains focused on its international initiatives. The decrease in other nuclear waste was primarily due to lower waste volume, partially offset by higher averaged price from waste mix. The decrease in revenue in the Services Segment was due to lack of projects due in part, to delay in procurement action resulting from the new Administration transition as previously discussed in the “Overview” section. Additionally, our Services Segment revenues are project based; as such, the scope, duration, and completion of each project vary.

25

Cost of Goods Sold

Cost of goods sold decreased $975,000 for the quarter ended March 31, 2025, compared to the quarter ended March 31, 2024, as follows:

|  |  |  |  | % |  |  |  |  |  | % |  |  |  |
(In thousands) |  | 2025 |  |  | Revenue |  |  | 2024 |  |  | Revenue |  |  | Change |
Treatment |  | $ | 8,936 |  |  |  | 97.3 |  |  | $ | 8,761 |  |  |  | 100.6 |  |  | $ | 175 |
Services |  |  | 4,326 |  |  |  | 91.4 |  |  |  | 5,476 |  |  |  | 111.6 |  |  |  | (1,150 | )
Total |  | $ | 13,262 |  |  |  | 95.3 |  |  | $ | 14,237 |  |  |  | 104.6 |  |  | $ | (975 | )

Cost of goods sold for the Treatment Segment increased by approximately $175,000 or 2.0%. Treatment Segment’s variable costs decreased by approximately $368,000 primarily due to lower disposal costs, partially offset by higher material and transportation costs. Treatment Segment’s overall fixed costs were higher by approximately $543,000 resulting from the following: salaries and payroll related expenses were higher by $556,000 due to higher headcount, attributed partly to the hiring of additional staff in connection with a certain waste stream as discussed in the “Overview” above. Also, salaries and payroll related expenses were higher in the first quarter of 2025 as more employees took vacation time in the first quarter of 2024 resulting in more hours charged to vacation accrual account; general expenses were higher by $113,000 primarily due to higher utility costs; maintenance expenses were higher by approximately $14,000; and regulatory expenses were lower by approximately $140,000. Services Segment cost of goods sold decreased by $1,150,000 or 21.0%. The decrease in cost of goods sold was primarily due to lower salaries/payroll related, outside services, and travel costs totaling approximately $1,513,000; lower general expenses by approximately $78,000 in various categories; and higher overall material and supplies, disposal, lab and regulatory expenses totaling approximately $441,000. The overall decrease in cost of goods sold within the Services Segment was attributed partly to cost cutting initiatives that we implemented in order to align expenses with revenue backlog. Additionally, cost of goods sold within our Services Segment are subject to variability as projects are competitively bid on. Included within cost of goods sold is depreciation and amortization expense of $421,000 and $404,000 for the three months ended March 31, 2025, and 2024, respectively.

Gross profit (loss)

Gross profit increased $1,277,000 for the quarter ended March 31, 2025, compared to the quarter ended March 31, 2024, as follows:

|  |  |  |  | % |  |  |  |  |  | % |  |  |  |
(In thousands) |  | 2025 |  |  | Revenue |  |  | 2024 |  |  | Revenue |  |  | Change |
Treatment |  | $ | 250 |  |  |  | 2.7 |  |  | $ | (52 | ) |  |  | (0.6 | ) |  | $ | 302 |
Services |  |  | 407 |  |  |  | 8.6 |  |  |  | (568 | ) |  |  | (11.6 | ) |  |  | 975 |
Total |  | $ | 657 |  |  |  | 4.7 |  |  | $ | (620 | ) |  |  | (4.6 | ) |  | $ | 1,277 |

Treatment Segment gross profit increased by $302,000 or approximately 580.8% and gross margin increased to 2.7% from (0.6)% primarily due higher revenue from overall higher waste volume, partially offset by overall lower averaged price from waste mix. The increase in fixed costs negatively impacted gross margin. Services Segment gross profit increased by $975,000 or 171.7% and gross margin increased to 8.6% from (11.6)%. The increase was attributed partly to cost cutting initiatives that we implemented within our Service Segment to align expenses with its revenue backlog as procurement cycles stabilize. Additionally, our overall Services Segment gross margin is impacted by our current projects which are competitively bid on and will therefore, have varying margin structures.

26

SG&A

SG&A expenses increased $471,000 for the three months ended March 31, 2025, as compared to the corresponding period for 2024, as follows:

(In thousands) |  | 2025 |  |  | % Revenue |  |  | 2024 |  |  | % Revenue |  |  | Change |
Administrative |  | $ | 1,923 |  |  |  | — |  |  | $ | 1,687 |  |  |  | — |  |  | $ | 236 |
Treatment |  |  | 1,356 |  |  |  | 14.8 |  |  |  | 1,065 |  |  |  | 12.2 |  |  |  | 291 |
Services |  |  | 736 |  |  |  | 15.6 |  |  |  | 792 |  |  |  | 16.1 |  |  |  | (56 | )
Total |  | $ | 4,015 |  |  |  | 28.8 |  |  | $ | 3,544 |  |  |  | 26.0 |  |  | $ | 471 |

Administrative SG&A expenses were higher primarily due to higher salaries, payroll related expenses and stock option compensation expenses totaling approximately $98,000. The hiring of the Company’s new COO in January 2025 contributed to this increase. Additionally, salaries and payroll related expenses were higher in the first quarter of 2025 as more employees took vacation time in the first quarter of 2024 resulting in more hours charged to vacation accrual account. Administrative Travel expenses were also higher by approximately $12,000 due trips made to the Company’s various facilities by the new COO. The remaining higher expenses in Administrative SG&A expenses were primarily due to higher outside services expenses by approximately $126,000 from more legal and consulting matters. Treatment Segment SG&A expenses were higher primarily due to higher salaries and payroll related expenses of approximately $204,000 as more employee hours were allocated to marketing initiatives of our new PFAS technology. Treatment Segment general expenses were also higher by approximately $87,000 primarily due to higher trade show expenses and higher expenses in various other categories. The decrease in Services Segment SG&A was primarily due to lower salaries and payroll related expenses totaling approximately $117,000, which was partially offset by higher general expenses of approximately $26,000 in various categories, higher travel expenses of approximately $9,000 and higher outside services expenses of approximately $26,000. Included in SG&A expenses is depreciation and amortization expense of $15,000 and $27,000 for the three months ended March 31, 2025, and 2024, respectively.

R&D

R&D expenses increased by approximately $87,000 in the first quarter of 2025 as compared to the corresponding period of 2024 primarily due to expenses incurred for our PFAS technology (see “Known Trends and Uncertainties – New Processing Technology” within this MD&A for a discussion of this technology).

Interest Income

Interest income increased by approximately $161,000 in the first quarter of 2025 as compared to the corresponding period of 2024 primarily due to interest income earned from funds deposited into our money market deposit account (“MMDA”) from the two equity raises that were completed in May 2024 and December 2024.

Income Taxes

We had income tax expense of $0 and income tax benefit of approximately $956,000 for continuing operations for the three months ended March 31, 2025, and 2024, respectively. Our effective tax rate was approximately 0% and 21.7% for the three months ended March 31, 2025, and 2024, respectively. Our effective tax rate for the three months ended March 31, 2025, was impacted by our recognition of a full valuation allowance against our U.S federal and state deferred tax assets in the quarter ended September 30, 2024. Our effective tax rate for the three months ended March 31, 2024, was impacted by non-deductible expenses and state taxes.

27

Liquidity and Capital Resources

Our cash flow requirements during the three months ended March 31, 2025, were primarily financed by our Liquidity (defined under our Loan Agreement as borrowing availability under the revolving credit plus cash in our MMDA maintained with our lender). 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 our Liquidity. 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 March 31, 2025, we had no outstanding borrowing under our revolving credit and our Liquidity was approximately $29,277,000. 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 the remainder of 2025, if we continue to incur losses such as in the first quarter of 2025, this could cause a reduction in our Liquidity.

The following table reflects the cash flow activities during the first three months of 2025 and 2024:

|  | Three months ended |
|  | March 31, |
(In thousands) |  | 2025 |  |  | 2024 |

Decrease in cash and finite risk sinking fund (restricted cash) |  | $ | (3,086 | ) |  | $ | (4,978 | )

As of March 31, 2025, we were in a positive cash position with no revolving credit balance. As of March 31, 2025, we had cash on hand of approximately $25,745,000.

Operating Activities

Cash used in operating activities of our continuing operations during the first quarter of 2025 consisted mostly of the significant net loss that we incurred of approximately $3,500,000, adjusted for certain non-cash items, such as $196,000 of stock-based compensation expenses and $436,000 of depreciation and amortization expenses. Cash flow increase of approximately $668,000 resulting from net change in assets and liabilities included a decrease in accounts receivable (net of provision for credit losses) of $2,248,000 and a decrease in deferred revenue of approximately $830,000. Our accounts receivables are impacted by timing of invoicing and collections. Our contracts with our customers are subject to various payment terms and conditions.

Cash used in operating activities of our continuing operations during the first quarter of 2024 consisted primarily of the significant net loss that we incurred of approximately $3,458,000, adjusted for certain non-cash items, which included $152,000 of stock-based compensation expenses, $431,000 of depreciation and amortization expense and deferred income tax benefit of $956,000. Cash flow decrease of approximately $646,000 resulting from net change in assets and liabilities included a decrease in accounts payables of approximately $1,603,000 and a decrease in accounts receivable (net of recovery of credit losses) of $1,032,000. Our accounts payable are impacted by the timing of our payments as we are continually managing payment terms with our vendors to maximize our cash position.

Cash used in operating activities of our discontinued operations in the first quarter of 2025 and 2024 consisted primarily of expenses incurred in connection with management and administration of regulatory matters for the Company’s remediation projects. Cash used in operating activities of our discontinued operations in the first quarter of 2025 was reduced by monthly rent payments of approximately $8,800, received from a tenant under a leasing agreement entered into on June 1, 2024, by our PFSG subsidiary, leasing a portion of the PFSG property.

28

We had working capital of $24,632,000 (which included working capital of our discontinued operations) as of March 31, 2025, as compared to working capital of $28,283,000 as of December 31, 2024. The decrease in our working capital was primarily due to the significant losses incurred from our operations as previously discussed.

Investing Activities

Cash used in investing activities of our continuing operations in the first quarter of 2025 consisted mostly of our purchases of property and equipment totaling approximately $655,000, of which $132,000 was financed. The remaining cash used in investing activities consisted of cash outlays made in connection with our operating permits and certain intangible assets.

Cash used in investing activities of our discontinued operations in the first quarter of 2025 consisted of payments made in connection with a certain regulatory permit at our PFSG subsidiary.

Cash used in investing activities of our continuing operations in the first quarter of 2024 consisted mostly of our purchases of property and equipment totaling approximately $288,000, of which $44,000 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 our purchases of property and equipment in 2025 as compared to 2024 was primarily due to capital expenditures made in connection with our PFAS technology which included the installation of our first unit in addition to upgrades made to the unit.

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. Our anticipated capital expenditures for 2025 include 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 and/or financing. The initiation and timing of our capital expenditures in 2025 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 used in financing during the first quarter of 2025 consisted mostly of principal payments of approximately $157,000 primarily for our Term and Capital Loans under our Credit Facility (see below for a discussion of our Credit Facility) principal payments of $71,000 for our finance leases, payments of $194,000 of offering costs from the equity raise that we completed in December 2024, partially offset by proceeds received from option exercises of approximately $41,000.

Our cash used in financing during the first quarter of 2024 consisted mostly of principal payments of approximately $259,000 for our Term and Capital Loans under our Credit Facility principal payments of $75,000 for our finance leases, partially offset by proceeds received from option and warrant exercises of approximately $209,000.

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, with PNC National Association (“PNC” and “lender”), acting as agent and lender (the “Loan Agreement”). The Loan Agreement provides us with a credit facility with a maturity date of May 15, 2027 (the “Credit Facility”) which consists of the following as of March 31, 2025: (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 March 31, 2025) and borrowing reductions that our lender may impose from time to time ($750,000 as of March 31, 2025); (b) a term loan (“Term Loan”) of $2,500,000, requiring monthly installments of $41,667; and (c) a capital expenditure loan (“Capital Loan”) of approximately $524,000, requiring monthly installments of principal of approximately $8,700 plus interest.

29

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

| ● | removed the quarterly fixed charge coverage ratio (“FCCR”) covenant testing requirement utilizing a twelve-month trailing basis; however, such FCCR testing requirement will be triggered on the day we fail to meet a minimum of $5,000,000 in daily Liquidity. If triggered, we will be required to show compliance of an FCCR ratio of not less than 1.15 to 1.00 utilizing a trailing twelve-month-period ended starting with the most recently reported fiscal quarter and each fiscal quarter thereafter. The FCCR testing requirement can be removed again once we are able to achieve a minimum of $5,000,000 in daily Liquidity for a thirty-consecutive-day period from the trigger date;
| ● | revised the Facility Fee (as defined) from .375% to .500%. Such fee percentage will revert back to .375% at such time that we are able to achieve a minimum 1.15 to 1.00 ratio in FCCR on a twelve-month trailing basis; and
| ● | required payment of an amendment fee of $12,500 by the Company, which is being amortized over the remaining term of the Loan Agreement as interest expense-financing fees.

Our Loan Agreement, as amended, with PNC, contains certain financial covenant requirements, along with customary representations and warranties. A breach of any of these financial covenant requirements, unless waived by PNC, could result in a default under our Loan Agreement allowing our lender to immediately require the repayment of all outstanding debt under our Loan Agreement and terminate all commitments to extend further credit. We met all of our financial covenant requirements in the first quarter of 2025. We expect to meet our covenant requirements under our Loan Agreement for the next twelve months.

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 March 31, 2025, the total amount of standby letters of credit outstanding totaled approximately $3,200,000 and the total amount of bonds outstanding totaled approximately $21,481,000. We also provide closure and post-closure requirements through a financial assurance policy for certain of our Treatment Segment facilities through AIG. As of March 31, 2025, the closure and post-closure requirements for these facilities were approximately $23,949,000.

Critical Accounting Policies and Estimates

There were no significant changes in our accounting policies or critical accounting estimates that are discussed in our Annual Report on Form 10-K for the year ended December 31, 2024.

Recent Accounting Pronouncements

See “Note 2 – Summary of Significant Accounting Policies” in the “Notes to Condensed Consolidated Financial Statements” for the recent accounting pronouncement that was adopted in the first quarter of 2025 and recent accounting pronouncements that will be adopted in future periods.

Known Trends and Uncertainties

Significant Customers. 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 indirectly as a subcontractor or directly as a prime contractor to federal government entities, representing approximately $8,404,00 or 60.4% of our total revenue during the three months ended March 31, 2025, as compared to $9,373,000 or 68.8% of our total revenue during the corresponding period of 2024.

30

Federal Funding. On March 15, 2025, the President signed a full-year Continuing Resolution (“CR”) that provides funding to federal government agencies through the rest of the fiscal year which ends September 30, 2025. Under the enactment of the CR, federal government entities continue to operate at the 2024 fiscal year budget approved level. 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. We have, in the past experienced delays in waste shipments and projects from certain federal government related customers resulting from numerous factors, including, but not limited to, impact of CR. Additionally, the mission to slash federal spending by the Department of Government Efficiency (“DOGE”) continues to contribute uncertainties in federal agencies from which we obtain, directly, or indirectly, government contracts. These aforementioned factors, among others, continue to create uncertainties in federal government spendings that 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.

Market Trends and Uncertainties. Macroeconomic conditions which include recent government and policy changes implemented in the United States, tariff actions and uncertainties related to trade wars, ambiguity around interest rates, softening labor markets, have created significant uncertainty in the global economy, volatility in the capital markets and recessionary pressures. We continue to monitor potential effects from these conditions that could impact our revenue and profitability which include supply chain challenges, cost volatility in goods that we utilize in our revenue production, and economic pressures on our customers that may result in reduced spending. While we have experienced limited impact from these conditions at this time, we continue to evaluate and implement a range of strategic options to manage potential impacts from these factors, including supply chain optimization, pricing strategies, sourcing adjustments and cost reduction measures in order to minimize impacts to our financial results.

New Processing Technology. We have 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 human-made 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 we 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 10,000 gallons of AFFF liquids to support ongoing operations, demonstration, and further testing of our System. We believe that we will receive an additional 50,000 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 fourth 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.

Environmental Contingencies

We are engaged in the waste management services segment of the pollution control industry. As a participant in the on-site treatment, storage and disposal market and the off-site treatment and services market, we are subject to rigorous federal, state and local regulations. These regulations mandate strict compliance and therefore are a cost and concern to us. Because of their integral role in providing quality environmental services, we make every reasonable attempt to maintain complete compliance with these regulations; however, even with a diligent commitment, we, along with many of our competitors, may be required to pay fines for violations or investigate and potentially remediate our waste management facilities.

31

We routinely use third party disposal companies, who ultimately destroy, or secure landfill residual materials generated at our facilities or at a client’s site. In the past, numerous third-party disposal sites have improperly managed waste and consequently require remedial action; consequently, any party utilizing these sites may be liable for some or all of the remedial costs. Despite our aggressive compliance and auditing procedures for disposal of wastes, we could further be notified, in the future, that we are a potentially responsible party (“PRP”) at a remedial action site, which could have a material adverse effect.

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. We expect to fund the expenses to remediate these sites from funds generated from operations. As of March 31, 2025, we had total accrued environmental remediation liabilities of $767,000, no change from the December 31, 2024 balance of $767,000. As of March 31, 2025, the total balance of the accrued environmental remediation liabilities was recorded as long-term.
