Risk factors and legal proceedings
The risks Perma-Fix Environmental Services names in Item 1A of its 10-K filed Mar 24, 2026: 40 risks under these headings, as written.5
- 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.
- Changes in government regulation, policy and programs could impact our business, affecting our profitability and future growth.
- 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.
- If we cannot maintain adequate insurance coverage, we will be unable to continue certain operations.
- 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.
- Our existing and future customers may reduce or halt their spending on hazardous waste and nuclear services with outside vendors, including us.
- Economic downturns, reductions in federal government funding or other events beyond our control could have a material negative impact on our businesses.
- The loss of one or a few customers could have an adverse effect on us.
- We are a holding company and depend, in large part, on receiving funds from our subsidiaries to fund our indebtedness.
- Our Treatment Segment has limited end disposal sites to utilize to dispose of its waste which could significantly 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.
- Our operations are subject to seasonal factors, which cause our revenues to fluctuate.
The other 28 risks
- We are engaged in highly competitive businesses and typically must bid against other competitors to obtain major contracts.
- 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.
- Adequate bonding is necessary for us to win certain types of new work and support facility closure requirements.
- If we cannot maintain our permits or cannot obtain required permits, we may not be able to continue or expand our operations.
- 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.
- Changes in environmental regulations and enforcement policies could subject us to additional liability and adversely affect our ability to continue certain operations.
- Our businesses subject us to substantial potential environmental liability.
- As our operations expand, we may be subject to increased litigation, which could have a negative impact on our future financial results.
- If environmental regulation or enforcement is relaxed, the demand for our services could decrease.
- 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.
- The elimination or any modification of the Price-Anderson Act’s indemnification authority could have adverse consequences for our business.
- If any of our permits, other intangible assets, and tangible assets become impaired, we may be required to record significant charges to earnings.
- 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.
- A lack of positive operating results could limit our borrowing capacity under our credit facility.
- If our financial and operating activities are limited, it could adversely affect our ability to incur additional debt to fund future needs.
- We may be unable to utilize loss carryforwards in the future.
- We sustained losses in each of the years 2025 and 2024 and our inability to become profitable on an annual basis in the foreseeable future could have a material adverse effect on our operations, credit facility, liquidity and potential growth.
- 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.
- We do not intend to pay dividends on our Common Stock in the foreseeable future.
- 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.
- Loss of certain key personnel could have a material adverse effect on us.
- We may not be successful in winning new business from our government, commercial or international customers.
- Our failure to maintain our safety record could have an adverse effect on our business.
- Systems failures, interruptions or breaches of security and other cybersecurity risks could have an adverse effect on our financial condition and results of operations.
- Climate change could negatively impact the Company’s operations and financial condition.
- Failure to obtain intellectual property protection for our proprietary technologies could negatively affect us.
- 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.
- 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.
