Annual 
Report

To Our Valued Shareholders,

2023  was  a  transformative  year  for  the  Company,  in  which  we 
laid  the  foundation  for  several  key  initiatives  that  we  believe 
will  be    highly  impactful  to  our  business,  starting  in  the  second 
half  of  2024  and  throughout  2025.  At  the  same  time, 
I  am 
pleased  to  report  we achieved  solid  financial  results  in  2023,  with 
revenue  increasing  by 27.1% and  gross  profit  increasing by 70.4% 
for  the  full  year.    Despite  investments 
internal 
bidding  organization  as  well  as  in  research  and  development, 
we  achieved  positive  EBITDA(1)  and positive net income in 2023.

Within  our  Treatment  Segment,  we  witnessed  an 
volume  with  steady  improvement  in  waste  receipts  early  in  the 
quarter.  This  included 
increased  waste  shipments  within  the 
commercial  sector  along  with  steady  sales  from  our  industrial 
waste programs.

Within  the  Services  Segment,  we  realized  several  new  strategic 
wins  from  the  Buffalo  Corp  of  Engineers,  the  U.S.  Geological 
Survey,  the  U.S.  Navy,  and  several  commercial  clients.  We  also 
developed  teaming  relationships  for  several  large  procurements.

the  next  7 years. Work  under this JV is beginning in Q1 2024, and 
the scope of work for  the  Company  is  expected  to  ramp  up  in  late 
2025.  Overall,  we  believe  these  strategic  awards  should  help  us 
further  diversify  our revenue streams.

In  addition  to  the  growth

We remain optimistic about reports coming from DFLAW in regard 
to  the  startup  of  the  melters  and  supporting  systems,  which 
continues  to  progress  towards  hot  commissioning  in  early  2025. 
This  waste,  estimated  by  DOE  to  be  over  8,000  cubic  meters 
annually, would more than double the production of all our plants 
combined on an annual basis. 

In addition, we have made important advances in a new technology 
to  treat  PFAS  (Per-and  Polyfluorinated  Substances)  contamination. 
Specifically, we completed pilot plant testing with PFAS destruction 
levels  exceeding  anticipated  regulatory  requirements.  We  are  now 
in  the  process  of  final  design  and  fabrication  for  installation  of  the 
first operational unit and plan to begin accepting commercial waste 
for destruction by the end of the year. We have established goals for 
additional  units  to  be  installed  at  each  of  our  existing  treatment 
plants. 

Finally,  we  are  expanding  our  waste  treatment  offering  within  the 
commercial  and  international  markets,  including  central  Europe, 
Mexico, and Canada. These opportunities would generate sustained 
receipts  beginning  in  2025,  providing  combined  annual  revenues 
estimated  at  over  $10  million,  which  we  expect  will  begin  in  late 
2024. 

The  first  half  of  2024 
looks  to  be  below  our  performance 
objectives, with a few temporary headwinds resulting from delays in 
procurements,  project  starts  and  waste  shipments,  due  in  part  to 
the  Continuing  Resolution  for  the  2024  federal  budget. However, 
we  remain  encouraged  by  the  long-term  outlook  for  the  business 
based  on  the  growing  project  opportunities,  sales  pipeline, 
and  potentially company-changing projects discussed above.  

We  truly  believe  our  best  years  are  ahead  and  we  look  forward  to 
advancing  our  mission  of  addressing  some  of  the  nation’s  most 
pressing  environmental  challenges.  I  would  like  to  thank  our 
shareholders,  employees  and  Board  of  Directors  for  your  ongoing 
support.  

Sincerely, 

Mark Duff 
President and Chief Executive Officer

PART I 

ITEM 1.   BUSINESS 
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  continue  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 a recently 
won foreign contract) 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 experienced significant improvement in our 2023 financial results as the lingering effects of COVID-19 
began  to  subside  starting  in  the  early  part  of  2022.  Our  Treatment  Segment  continued  to  see  steady 
improvements in waste receipts from certain customers who had previously delayed waste shipments due, in 
part,  from  the  impact  of  COVID-19.  Within  our  Services  Segment,  certain  projects  which  were 
delayed/curtailed in the first part of 2022 due, in part, from the lingering effects of the COVID-19, achieved 
full  operational  status  and  improved  productivity  in  2023  which  positively  impacted  revenue.  Revenues 
from both of our Segments were also positively impacted from contracts won in 2023 as procurement and 
planning on behalf of our government clients continued to progress as the lingering effects of COVID-19 
pandemic subsided.  

Heading into 2024, we expect to see overall continue steady improvements in waste receipts and increases 
in project work from certain existing contracts, contracts won in 2023, and bids submitted in both segments 
that are awaiting awards. However, due to our operations which is subject to seasonal factor, we generally 
experience  lower  revenue  in  the  first  quarter  due  to  overall  reduced  activities  by  our  customers  from  the 
usual  slowdown  in  operations  due,  in  part,  from  returning  from  the  holiday  periods  and  poorer  weather 
conditions. Additionally, due to Congress’s inability to timely approve FY 2024 budget and the extension of 
the  continuing  resolution,  certain  of  our  government  related  customers  have  informed  us  that  waste 
shipments will likely be delayed. Although we expect to see overall improvements in revenue in 2024 as 
disclosed  above, if  Congress  is  unable to  enact  the  full  FY  2024  appropriation bills  or  further extend the 
continuing resolutions to fund government spending by the late March deadline, the U.S. government will 
enter  into  a  partial  shutdown.  The  full  impact  of  any  additional  continued  resolution  beyond  March  or  a 
partial  government  shutdown  is  uncertain.  If  a  partial  government  shutdown  were  to  occur  and  were  to 
continue an extended period, our financial results of operations could be negatively impacted by delays in 
procurement  actions,  waste  shipments  and  project  delays  on  newly  awarded  projects  (See  “Item  7. 
Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations  –  for  a  full 
discussion of the Company’s results of operations for 2023). 

Segment Information and Foreign and Domestic Operations and Sales 
For  2023,  we  have  two  reportable  segments.  In  accordance  with  Financial  Accounting  Standards  Board 
(“FASB”) Accounting Standards Codification (“ASC”) 280, “Segment Reporting”, we define an operating 
segment as: 






a business activity from which we may earn revenue and incur expenses;
whose  operating  results  are  regularly  reviewed  by  the  chief  operating  decision  maker  “(CODM”) to
make decisions about resources to be allocated and assess its performance; and
for which discrete financial information is available.

Foreign Revenue and Initiative 
As noted previously, we continue to increase our focus on expansion into international markets.   

On December 18, 2023, the joint venture (“JV”) where we and Campoverde Srl (“JV partner”) each owns 
50% of the partnership, was 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.  Work  under  this  JV  has  not  started  as  of  December  31,  2023.  The 
scope of work to be performed in the initial phases of this contract will be performed predominately by our 
JV partner. Revenue generated by us under the initial phases will be limited to project management support 
through 2025. 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. 

During  March  2022,  we  signed  a  non-binding  joint  venture  term  sheet  addressing  plans  to  partner  with 
Springfields  Fuels  Limited  (“SFL”), an  affiliate  of Westinghouse  Electric  Company  LLC, to  develop  and 
manage a nuclear waste-materials treatment facility (the “Facility”) in the United Kingdom. The Facility is 
for the purpose of expanding the partners’ waste treatment capabilities for the European nuclear market. It is 
expected that upon finalization of a partnership agreement, SFL will have an ownership interest of fifty-five 
(55) percent and our interest will be forty-five (45) percent. The finalization, form and capitalization of this 
unpopulated  partnership  is  subject  to  numerous  conditions,  including  but  not  limited  to,  completion  and 
execution of a definitive agreement and facility design, granting of required regulatory, lender or permitting 
approvals  and  updated  cost  and  profitability  analysis  based  on  current  and  forecast  future  economic 
conditions. Upon finalization of this venture, we will be required to make an investment in this venture. The 
amount  of  our  investment,  the  period  of  which  it  is  to  be  made  and  the  method  of  funding  are  to  be 
determined.  

Our consolidated revenue for 2023 and 2022 included approximately $2,066,000, or 2.3%, and $1,226,000, 
or 1.7%, respectively, from foreign customers.  

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, 
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 
3 

 
 
 
 
 
 
 
 
 
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 is 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 such would allow 
companies to enter into these markets and provide greater competition.   

Number of Employees 
At December 31, 2023, we employed approximately 297 employees, of whom 288 are full-time employees 
and 9 are part-time/temporary employees. None of our current employees are unionized.  

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.  This  supplemental  capability  would  support  DOE’s 
glassifying process provided by the Hanford Vitrification Plant for safe transport and disposal off-site.   

Environmental, Social and Governance (“ESG”) 
We  have  a  ESG  subcommittee  under  our  Corporate  Governance  and  Nominating  Committee  to  provide 
guidance  on  ESG management.  Our  executive  team is  responsible for the  continuing  development  of  our 
ESG strategic roadmap with support from management from key functional areas. The key areas of focus 
under  our  ESG  initiatives  continue  to  be  health  and  safety,  environmental  performance,  DEI  (diversity, 
equality and inclusion), talent retention and development, corporate governance and climate-forward service 
development that support our customers’ transition to low carbon economy. Our executive team is involved 
in policy planning and coordination of corporate-wide ESG efforts. See our website at https://www.perma-
fix.com/esg.aspx  for some highlights of  our  ESG initiatives as  well  as our policies  under  our  ESG as  we 
continue to improve our ESG initiatives. The information on our website is not part of, or incorporated by 
reference in this Form 10-K.  

Dependence Upon a Single or Few Customers 
Our Treatment and Services Segments have significant relationships with the U.S. governmental authorities. 
A significant amount of our revenues from our Treatment and Services Segments are generated indirectly as 
subcontractors  for  others  who  are  prime  contractors  to  government  authorities,  particularly  the  DOE  and 
DOD, or directly as the prime contractor to government authorities. The contracts that we are a party to with 
others  as  subcontractors  to  the  U.S  federal  government  or  directly  with  the  U.S  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 U.S government 

4 

 
 
 
 
 
 
 
 
 
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 government clients (domestic), either indirectly for 
others  as  a  subcontractor  to  government  entities  or  directly  as  a  prime  contractor  to  government  entities, 
representing  approximately  $70,642,000  or  78.7%,    of  our  total  revenue  during  2023,  as  compared  to 
$59,658,000, or 84.5%, of our total revenue during 2022.  

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 treatment facilities in Oak 
Ridge, TN and Erwin, TN and treatment/disposal facilities for low level radioactive waste in Clive, UT and 
Barnwell,  SC.  Waste  Control  Specialists,  which  has  licensed  treatment/disposal  capabilities  for  low  level 
radioactive  waste  in  Andrews,  TX,  is  also  a  competitor  in  the  treatment  market  with  increasing  market 
share.  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  America  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  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  provide  a  challenge  to  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, which 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,  2023,  we  had  total  accrued  environmental  remediation  liabilities  of  $845,000,  a 
decrease of $16,000 from the December 31, 2022, balance of $861,000. The decrease represents payments 
for remediation projects. As of December 31, 2023, $61,000 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, 
5 

 
 
 
 
 
 
 
 
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 $561,000 and $336,000 for 2023 and 2022, respectively.  

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 
6 

 
 
 
 
 
 
 
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  the  USNRC 
oversight), Office of Radiation Control, regulates the licensing and radiological program of the PFF facility; 
the State of Tennessee (with the 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  the  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.  

ITEM 1A. 

RISK FACTORS 

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 

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. 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 
and similar to, or greater than, the coverage maintained by other companies in the industry of our size.  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. 

7 

 
 
 
 
 
 
The  inability  to  maintain  existing  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 
government contracts or subcontracts. Most of our government contracts or our subcontracts granted under 
government  contracts  are  awarded  through  a  regulated  competitive  bidding  process.  Some  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,  the  U.S  federal  government  are  generally  terminable  for 
convenience at any time at the option of the governmental agency. The multi-year contract that was awarded 
to us and our JV partner, Campoverde Srl, by the European Commission (the “Contracting Authority”) on 
December 18, 2023, for the treatment of radioactive waste from the Joint Research Center in Ispra, Italy as 
discussed previously may be terminated by the Contracting Authority under certain conditions as set forth in 
the contract. 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 (including government clients) to reduce or 
halt  their  spending  on  hazardous  waste  and  nuclear  services  from  outside  vendors,  including  us.  These 
factors include, but are not limited to: 

 

 

accidents, terrorism, natural disasters or other incidents occurring at nuclear facilities or involving 
shipments of nuclear materials; 
failure  of  government  to  approve  necessary  budgets,  or  to  reduce  the  amount  of  the  budget 
necessary, to fund remediation sites, including DOE and DOD sites; 

  government shut-downs; 
 
 
 

civic opposition to or changes in government policies regarding nuclear operations;  
a reduction in demand for nuclear generating capacity; or 
failure to perform under existing contracts, directly or indirectly, with the government. 

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  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. 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), 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 

8 

 
 
 
 
 
 
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  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  from  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 currently 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 
9 

 
 
 
 
 
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. If we are unable to meet these competitive 
challenges, 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. 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.  If 
these audits result in determinations that costs claimed as reimbursable are not allowed costs or were not 
10 

 
 
 
 
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:  

 

 

 

claims for clean-up costs, personal injury or damage to the environment in cases in which we are 
held responsible for the release of hazardous or radioactive 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. 

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, 

11 

 
 
 
 
 
 
 
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 contractor, 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 

12 

 
 
 
 
 
 
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 the first quarter of 2023 but 
otherwise met all of our other financial covenant requirements. We met all of our covenant requirements in 
each  of  the  remaining  quarters  of  2023.  In  the  past,  when  we  failed  to  meet  our  minimum  FCCR 
requirement in certain instances, 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 borrow under our credit facility could adversely affect our operations. 
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, 2023, we had no borrowing under the revolving part of our credit facility and borrowing availability of 
up to an additional $10,622,000, which included our cash (deposited with our lender) and was based on our 
eligible receivables and was net of approximately $3,950,000 in outstanding standby letters of credit and a 
$750,000 indefinite reduction in borrowing availability that our lender imposed. 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: 

 

required  to  dedicate  a  substantial  portion  of  our  cash  flow  to  the  payment  of  principal  and 
interest, thereby  reducing the funds  available  for operations and  future business opportunities; 

  make it more difficult for us to satisfy  our obligations; 
 

limit  our  ability  to  borrow  additional  money  if needed  for  other  purposes, including  working 
capital, capital  expenditures, debt  service  requirements, acquisitions and  general  corporate  or 
other purposes, on satisfactory terms  or at all; 
limit our ability  to adjust  to changing economic,  business and  competitive conditions; 

 
  place  us  at  a  competitive  disadvantage with  competitors who  may  have  less  indebtedness or 

greater access  to financing; 

  make  us  more  vulnerable  to  an  increase  in  interest  rates,  a  downturn  in  our  operating 

performance or a decline  in general  economic  conditions;  and 

  make  us more  susceptible to changes in credit  ratings, which could  impact  our ability  to obtain 

financing  in the future  and  increase  the cost of such financing. 

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.  

We may be unable to utilize loss carryforwards in the future. 
We  have approximately  $19,450,000  and $72,859,000  in  net operating  loss  carryforwards  for  federal  and 

13 

 
 
 
 
 
state income tax purposes, respectively and expires in various amounts starting in 2023 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.    Further,  our  net  loss  carryforwards  have  not  been 
audited or approved by the Internal Revenue Service. 

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 
membership interest of our stockholders and the dilution in ownership value. As of December 31, 2023, we 
had  13,646,559  shares  of  Common  Stock  outstanding.  In  addition,  as  of  December  31,  2023,  we  had 
outstanding options to purchase 994,500 shares of our Common Stock at exercise prices ranging from $3.15 
to $9.81 per share and an outstanding warrant to purchase 30,000 shares of our Common Stock at exercise 
price  of  $3.51  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 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. 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.  In  addition,  many  of  our  government  and  commercial 
14 

 
 
 
 
 
 
 
 
 
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.  

We believe our proprietary technology is important to 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 effect on 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 
15 

 
 
 
 
 
 
 
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.  If  we  are  unable  to  maintain  adequate  internal  control  over  financial  reporting,  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  General  Corporation  Law  of  Delaware,  an  anti-takeover 
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. 

At  December  31,  2023,  out  of  30,000,000  shares  of  our  Common  Stock  authorized,  we  had  13,646,559 
shares of common stock outstanding and 7,642 shares of treasury stock. In addition, at December 31, 2023, 
we had outstanding options to purchase 994,500 shares of our common stock at exercise prices ranging from 
$3.15 to $9.81 per share, and an outstanding warrant to purchase 30,000 shares of our Common Stock at an 
exercise price of $3.51 per share. Assuming the issuance of the Common Stock underlying such options and 
warrant, at December 31, 2023, we had available for future issuance 15,321,299 shares of authorized and 
unissued  Common  Stock,  and  2,000,000  shares  of  our  preferred  stock.  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. 

Third party expectations relating to ESG factors may impose additional costs and expose us and our 
clients to new risks. 
There  is  an  increasing  focus  from  certain  investors  and  certain  of  our  customers,  and  other  stakeholders 
concerning  corporate  responsibility,  specifically  related  to  ESG factors.  Some  investors  may  use  these 
factors to guide their investment strategies and, in some cases, may choose not to invest in us, or otherwise 
do business with us, if they believe our policies relating to corporate responsibility are inadequate or do not 
align  with theirs.  Third party providers of corporate responsibility ratings  and  reports  on  companies  have 
increased in number, resulting in varied standards. In addition, the criteria by which companies’ corporate 
responsibility practices are assessed are evolving, which could result in greater expectations of us and cause 
us to undertake costly initiatives to satisfy such new criteria. Alternatively, if we elect not to or are unable to 
satisfy such new criteria or do not meet the criteria of a specific third-party provider, some investors may 
conclude that our policies with respect to corporate responsibility are inadequate. We may face reputational 
damage in the event that our corporate responsibility procedures or standards do not meet the standards set 
by  various  constituencies.  If  we  fail  to  satisfy  the  expectations  of  investors,  our  customers  and  other 
stakeholders  or  our  initiatives  are  not  executed  as  planned,  our  reputation  and  financial  results  could  be 
adversely  affected  and  our  revenues,  results  of  operations  and  ability  to  grow  our  business  may  be 
negatively impacted. Additionally, new legislative or regulatory initiatives related to ESG could adversely 
affect our business.

CYBERSECURITY 

Cybersecurity Risk Management and Strategy 
The  Company  recognizes  the  importance  of  identifying,  assessing,  and  managing  risks  associated  with 
cybersecurity threats. The Company’s cybersecurity program utilizes components of the National Institute 
of  Standards  and Technology  (“NIST”)  Cybersecurity  Framework.   Key  components  of  our cybersecurity 
program  include  governance,  risk  management,  access  and  authentication  controls,  change  management, 
audit  and  assessment,  awareness  and  training,  contingency  planning,  recovery,  media  handling,  incident 
response, personnel and physical security, and communication integrity.  

Our  program  is  embedded  into  Information Technology  (“IT”)  and  Information  System  (“IS”)  operations 
across  the  business  with  a  focus  on  awareness,  transparency,  minimizing  business  impacts,  and  reducing 
enterprise  risk,  including  strategic,  compliance,  legal  and  financial  risk.  The  Company  has  policies  and 
procedures  in  place  to  ensure  compliance  with  its  cybersecurity  program  and  cybersecurity  controls.  Our 
program  relies  on  a  philosophy  of  continuous  improvement  by  using  periodic  self-assessments,  3rd  party 
assessments,  and  customer/agency  audits  to  determine  cyber  control  presence,  applicability,  and 
effectiveness.  Our  program  is  customized  with  additional  controls  that  address  financial  systems  risk, 
nuclear  quality  assurance,  Sarbanes  Oxley,  European  Union  cyber  and  data  protection  requirements,  and 
supply chain risks.   

Our  risk  management  process  addresses  confidentiality,  availability,  and  integrity  and  includes  evaluating 
information  systems  specific  threats,  vulnerabilities,  likelihood,  and  potential  impact.    Impact  thresholds, 
which are reviewed and approved by the Board of Directors (the “Board”) and senior management, are used 
to define incident escalation paths from IT operations to management, the Audit Committee and the Board. 
This process is used to identify, manage, and communicate material risks to the business. Additional cyber 
incident reporting requirements are in place to comply with customers and regulatory agency requirements.   

Automated  threat  and  vulnerability  management  systems  are  in  place  and  updated  per  industry  standards 
and  best  practices.  Our  IT  team  further  manages  risk  by  evaluating  external  providers  of  threat, 
vulnerability,  and  risk  mitigation  information.    This  information  is  used  to  proactively  implement  new 
methods or controls for reducing risk associated with a particular emerging threat or vulnerability.  

The  Company’s  cybersecurity  program  is  managed  by  the  Vice  President  (“VP”)  of  IS,  who  has  been 
employed by the Company for 20 years and has over  35 years of total experience in information systems.  
The  VP  of  IS  has  an  extensive  career  in  software  development  and  infrastructure  management  including 
working with Fortune 500 companies in his prior positions.  The VP of information system is a participant 
in the overall Company strategic process and has aligned the program to best service the strategic objectives 
of the business. 

Cybersecurity Governance 
The  Company’s  Audit  Committee  has  oversight  responsibility  for  risks  and  incidents  relating  to 
cybersecurity threats. Our senior management is responsible for the day-to-day management of the material 
risks we face. Our VP Of Information System is scheduled to report to the CFO on a weekly basis and the 
Audit Committee on a quarterly basis on cybersecurity matters to include updates on cybersecurity threat 
management, strategy processes, system updates and cybersecurity risks activities, including but not limited 
to any recent cybersecurity incidents and related responses. Our Board is also engaged in discussion with 
senior  management  and  the  Audit  Committee  at  least  on  a  quarterly  basis  on  cybersecurity  matters  to 
discuss any updates to our cybersecurity risk management and strategy program. Each member of our Board 
has a working knowledge and/or experience with cybersecurity, IT strategy and IT risk assessment. 

In  the  past  2  years,  the  Company  does  not  believe  that  it  has  experienced  any  material  cybersecurity 
incidents, nor any material costs related to immaterial cyber incidents. Although we have a comprehensive 
process for the prevention of material cybersecurity incidents as discussed, we cannot provide assurance that 
our results of operations and financial condition and business strategy will not be materially impacted from 
cybersecurity risks in the future. For more information on our cybersecurity related risk and potential effects

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION 
AND RESULTS OF OPERATIONS 

Certain  statements  contained  within  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”).  See  “Special  Note  regarding  Forward-Looking 
Statements” contained in this report. 

Management's  discussion  and  analysis  is  based,  among  other  things,  our  audited  consolidated  financial 
statements  and  includes  our  accounts  and  the  accounts  of  our  wholly-owned  subsidiaries.  Our  2022 
consolidated financial statements also included the accounts of a variable interest entity (“VIE”) for which 
we  were  the  primary  beneficiary.  During  the  fourth  quarter  of  2022,  project  work  under  this  VIE  was 
completed. 

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 experienced significant improvement in our 2023 financial results as the lingering effects of COVID-19 
began  to  subside  starting  in  the  early  part  of  2022.  Our  Treatment  Segment  continued  to  see  steady 
improvements in waste receipts from certain customers who had previously delayed waste shipments due, in 
part,  from  the  impact  of  COVID-19.  Within  our  Services  Segment,  certain  projects  which  were 
delayed/curtailed in first part of 2022 due, in part, from the lingering effects of the COVID-19, achieved full 
operational  status  and  improved  productivity  in  2023  which  positively  impacted  revenue.  Revenue  from 
both  of  our  Segments  were  also  positively  impacted  from  contracts  won  in  2023  as  procurement  and 
planning on behalf of our government clients continued to progress as the lingering effects of COVID-19 
pandemic subsided.  

19 

 
 
 
 
 
 
 
 
 
 
  
 
 
Revenue  increased  by  $19,136,000  or  27.1%  to  $89,735,000  for  the  twelve-months  ended  December  31, 
2023, from $70,599,000 for the corresponding period of 2022. We saw increases in both Segments where 
Treatment  Segment  revenue  increased  by  $10,119,000  or  30.3%  to  $43,477,000  from  $33,358,000  and 
Services  Segment  revenue  increased  by  $9,017,000  or  24.2%  to  $46,258,000  from  $37,241,000.  The 
increase in revenue in the Treatment Segment was primarily due to overall higher waste volume which was 
offset  by  lower  averaged  price  from  waste  mix.  The  increase  in  revenue  in  the  Services  Segment  was 
primarily due to achievement of full operational status and improved productivity on certain projects which 
had  been  delayed/curtailed  in  2022  due,  in  part,  from  the  lingering  effects  of  the  COVID-19  pandemic. 
Total gross profit for 2023 increased $6,760,000 or 70.4% due to increased revenue. Selling, General, and 
Administrative (“SG&A”) expenses increased $323,000 or 2.2% for the twelve-months ended December 31, 
2023, as compared to the corresponding period of 2022.   

In  March  2023,  we  received  the  Employee  Retention  Credit  (“ERC”)  of  $1,975,000  that  we  applied  for 
during the third  quarter of 2022  as  permitted  under  the  Coronavirus  Aid,  Relief and  Economic  Securities 
Act,  as  amended  (the  “CARES  Act”).  In  addition  to  the  $1,975,000,  we  also  received  approximately 
$60,000 in interest (recorded within “Interest Income” on our Consolidated Statements of Operations).   

We  believe  we  have  sufficient  liquidity  on  hand  to  continue  business  operations  during  the  next  twelve 
months. See a discussion of our liquidity overview within this MD&A – “Liquidity and Capital Resources.” 

Heading into 2024, we expect to see overall continue steady improvements in waste receipts and increases 
in project work from certain existing contracts, contracts won in 2023, and bids submitted in both segments 
that are awaiting awards. However, due to our operations which is subject to seasonal factor, we generally 
experience  lower  revenue  in  the  first  quarter  due  to  overall  reduced  activities  by  our  customers  from  the 
usual  slowdown  in  operations  due,  in  part,  from  returning  from  the  holiday  periods  and  poorer  weather 
conditions. Additionally, due to Congress’s inability to timely approve FY 2024 budget and the extension of 
the  continuing  resolution,  certain  of  our  government  related  customers  have  informed  us  that  waste 
shipments will likely be delayed. Although we expect to see overall improvements in revenue in 2024 as 
disclosed  above, if  Congress  is  unable to  enact  the  full  FY  2024  appropriation bills  or  further extend the 
continuing resolutions to fund government spending by the late March deadline, the U.S. government will 
enter  into  a  partial  shutdown.  The  full  impact  of  any  additional  continued  resolution  beyond  March  or  a 
partial  government  shutdown  is  uncertain.  If  a  partial  government  shutdown  were  to  occur  and  were  to 
continue an extended period, our financial results of operations could be negatively impacted by delays in 
procurement actions, waste shipments and project delays on newly awarded projects. 

Business Environment  
Our  Treatment  and  Services  Segments’  business  continues  to  be  heavily  dependent  on  services  that  we 
provide  to  governmental  clients,  primarily  as  subcontractors  for  others  who  are  prime  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, the 
economic conditions and the manner in which the applicable government will be required to spend funding 
to  remediate  various  sites  and  a  potential  partial  government  shutdown.  In  addition,  our  governmental 
contracts  and  subcontracts  relating  to  activities  at  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.   

We are continually reviewing methods to raise additional capital to supplement our liquidity requirements, 
when  needed,  and  reducing  our  operating  costs.  We  continue  to  aggressively  bid  on  various  contracts, 
including potential contracts within the international markets. On December 18, 2023, the JV where we and 
Campoverde  Srl  (“JV  partner”)  each  owns  50%  of  the  partnership,  was  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. Work under this JV has not 
started as of December 31, 2023. The scope of work to be performed in the initial phases of this contract 
will be performed predominately by our JV partner. Revenue generated by us under the initial phases will 
20 

 
 
 
 
 
 
be limited to project management support through 2025. 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. Once activities commence under 
this JV, we will consolidate the operations of this JV into our financial statements. 

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

1)  Includes  wastes  generated  by  government  clients  of  $2,943,000  and  $2,380,000  for  the  twelve  months  ended 
December 31, 2023, and 2022, respectively. 

Treatment Segment revenue increased by $10,119,000 or 30.3% for the twelve-months ended December 31, 
2023 over the same period in 2022. The overall increase was primarily due to higher waste volume offset by 
lower  averaged  price  from  waste  mix.  As  previously  disclosed,  starting  in  the  latter  part  of  the  second 
quarter of 2022, our Treatment Segment began to see steady improvements in waste receipts from certain 
customers who had previously delayed waste shipments due, in part, from the lingering effects of COVID-
21 

 
 
 
 
 
   
   
      
     
      
     
      
     
        
     
      
     
      
     
           
           
             
             
           
       
      
           
             
          
          
            
            
            
        
       
           
       
       
      
             
          
       
      
 
      
      
        
        
        
        
      
      
      
        
        
      
      
    
    
 
19.  Services  Segment  revenue  increased  by  approximately  $9,017,000  or  24.2%.  primarily  due  to 
achievement  of  full  operational  status  and  improved  productivity  on  certain  projects  which  had  been 
delayed/curtailed  in  the  early  part  of  2022  due,  in  part,  from  the  lingering  effects  of  the  COVID-19 
pandemic. Our Services Segment revenues are project-based; as such, the scope, duration, and completion 
of each project vary. As a result, our Services Segment revenues are subject to differences relating to timing 
and project value. Revenues from both of our segments were also positively impacted from contracts won in 
2023. 

Cost of Goods Sold 
Cost of goods sold increased $12,376,000 for the year ended December 31, 2023, as compared to the year

Cost of goods sold for the Treatment Segment increased by approximately $8,486,000 or 30.2%. Treatment 
Segment’s  variable  costs  increased  by  approximately  $6,189,000  primarily  due  to  higher  material  and 
supplies, disposal, lab, outside services costs and higher employee incentives. Treatment Segment’s overall 
fixed  costs  were  higher  by  approximately  $2,297,000  resulting  from  the  following:  salaries  and  payroll 
related expenses were higher by approximately $1,483,000 due to higher headcount; depreciation expenses 
were higher by approximately $393,000 due to depreciation for asset retirement obligations in connection 
with our EWOC facility; general expenses were higher by approximately $279,000 primarily due to higher 
utility  costs;  maintenance  costs  were  higher  by  approximately  $235,000;  travel  expenses  were  higher  by 
approximately $90,000; and regulatory expenses were lower by approximately $183,000. Services Segment 
cost  of  goods  sold  increased  $3,890,000  or  11.8%  due  to  higher  revenue.  The  overall  increase  in  cost  of 
goods sold was primarily due to the following: aggregated higher salaries/payroll related, outside services, 
and travel costs totaling approximately $4,356,000; higher depreciation expenses of $63,000; lower material 
and  supplies,  lab,  regulatory  and  disposal  expenses  totaling  approximately  $444,000;  and  lower  general 
expenses by approximately $85,000 in various categories. Included within cost of goods sold is depreciation 
and amortization expense of $2,484,000 and $2,027,000 for the twelve months ended December 31, 2022, 
and 2021, respectively.

Treatment  Segment  gross  profit  increased  by  $1,633,000  or  31.1%  primarily  due  to  higher  revenue  as 
discussed  previously.  Despite  the  slight  increase  in  gross  margin,  Treatment  Segment  gross  margin  was 
negatively  impacted  by  higher  variable  costs  from  waste  mix  and  the  impact  of  overall  increase  in  fixed 
costs. Services Segment gross profit increased by $5,127,000 or 117.4% and gross margin increased from 
11.7%  to  20.5%  primarily  due  to  higher  revenue  and  improved  margin  projects.  Our  overall  Services 
Segment gross margin is impacted by our current projects which are competitively bid and therefore have 
varying margin structures. 

SG&A 
SG&A  expenses  increased  $323,000  for  the  year  ended  December  31,  2023,  as  compared  to  the

Administrative SG&A expenses were higher primarily due to the following: payroll-related expenses were 
higher  by  approximately  $660,000  primarily  due  to  higher  accrued  employee  incentives  (including  our 
management incentive plans (“MIPs”)) and higher 401(k) matching expenses as payroll expenses in 2022 
included more forfeitures of 401(k) plan matching funds contributed by us for former employees who failed 
to  meet  the  401(k)  plan  vesting  requirements;  outside  services  expenses  were  lower  by  approximately 
$256,000 as a result of fewer audit/consulting matters; and general expenses were lower by approximately 
$56,000  in  various  categories.  Treatment  Segment  SG&A  expenses  were  lower  primarily  due  to  the 
following:  outside  services  expenses  were  lower  by  approximately  $110,000  due  to  fewer  consulting 
matters; salaries and payroll related expenses were lower by approximately $212,000; travel expenses were 
lower by approximately $24,000; and general expenses were higher by approximately $176,000 in various 
categories.  The  increase  in  SG&A  expenses  within  our  Services  Segment  was  primarily  due  to  the 
following:  salaries/payroll-related  expenses  were  higher  by  approximately  $92,000  due  to  more 
administrative  support  functions  required  as  the  result  of  higher  revenue;  travel  expenses  were  higher  by 
approximately $43,000; credit losses on accounts receivable were higher by approximately $59,000, as in 
the first quarter of 2022 our Services Segment collected on certain accounts that were previously deemed to 
be uncollectible; outside services expenses were lower by approximately $41,000 due to fewer consulting 
matters; and general expenses were lower slightly by $8,000. Included in SG&A expenses is depreciation 
and  amortization  expense  of  $84,000  and  $82,000  for  the  twelve  months  ended  December  31,  2023  and 
2022, respectively.  

Interest Income 
Interest  income  increased  by  approximately  $507,000  for  the  twelve-months  ended  December  31,  2023, 
respectively, as compared to the corresponding period of 2022 primarily due to higher interest earned from 
the  finite  risk  sinking  fund.  Interest  income  for  2023  also  included  approximately  $60,000  received  in 
March 2023 under the ERC program under the CARES Act. 

Interest Expense 
Interest expense increased by approximately $148,000 for the twelve-months ended December 31, 2023, as 
compared  to  the  corresponding  period  of  2022  due  to  interest  incurred  on  the  new  $2,500,000  term  loan 
dated July 31, 2023, under our credit facility. Interest expense was also higher in 2023 from higher interest 
rate on our term loan dated May 8, 2020, which was offset by the declining term loan balance. Additionally, 
the increase in interest expense in 2023 was also the result of interest incurred from advances made in May 
of 2022 from the capital line under our credit facility. 

Income Taxes 
We had income tax expense of $17,000 and income tax benefit of $378,000 for continuing operations for 
the  twelve-months  ended  December  31,  2023  and  2022,  respectively.  Our  effective  tax  rates  were 
approximately  1.8%  and  10.5%  for  the  twelve-  month  ended  December  31,  2023  and  2022,  respectively. 
Our effective tax rates for the twelve-months ended December 31, 2023, and 2022 were 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, 2023, our Treatment Segment had a 
backlog of approximately $8,702,000, as compared to approximately $9,156,000 as of December 31, 2022. 
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,  2023  and  2022.  
We  incurred  net  losses  of  $433,000  (net  of  tax  benefit  of  $117,000)  and  $605,000  (net  of  tax  benefit  of 
$199,000)  for  our  discontinued  operations  for  the  twelve-months  ended  December  31,  2023,  and  2022, 
respectively.  In  2022,  we  incurred  additional  costs  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, 2023, were primarily financed 
by our operations, cash on hand (which included the ERC, along with interest, that we received in March 
2023 and proceeds from a new term loan dated July 31, 2023, in the amount of $2,500,000 provided to us 
under  an  amendment  to  our  existing  credit  facility),  and  credit  facility  availability.  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, and planned capital expenditures. We plan 
to fund these requirements from our operations, credit facility availability, cash on hand and collections of 
unpaid receivables (See “Known Trends and Uncertainties – Perma-Fix Canada, Inc. (“PF Canada”)” for a 
discussion of unpaid receivables due to our Perma-Fix Canada, Inc. subsidiary from a certain customer in 
which a settlement agreement has been reached, subject to meeting certain conditions/terms precedent and a 
partial payment received in January 2024). Our ability to utilize our credit facility from our lender is subject 
to meeting our quarterly financial covenant requirements, among other things. We continue to explore all 
sources of increasing our capital and/or liquidity and to improve our revenue and working capital, including, 
but  not limited to  entering  into  equity transactions.  There  are  no  assurances that  we  will be successful  in 
increasing our liquidity through our efforts. 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, when necessary. As of December 31, 2023, our borrowing availability under our revolving 
part  of  our  credit  facility  was  approximately  $10,622,000,  which  included  our  cash  (deposited  with  our 
lender) and was based on our eligible receivables and was net of approximately $3,950,000 in outstanding 
standby  letters  of  credit  and  a  $750,000  indefinite  reduction  in  borrowing  availability  that  our  lender 
imposed pursuant to the July 31, 2023 amendment of our Loan Agreement. We believe that our cash flows 
from operations, our available liquidity from our credit facility, and our cash on hand should be sufficient to 
fund our operations for the next twelve months.  

The  following  table  reflects  the  cash  flow  activity  for  the  year  ended  December  31,  2023,  and  the 
corresponding period of 2022:

Operating Activities 
Accounts  receivable,  net  of  credit  losses,  totaled  $9,722,000  as  of  December  31,  2023,  an  increase  of 
$358,000  from  the  December  31,  2022,  balance  of  $9,364,000.  The  increase  was  attributed  to  increased 
revenue, timing of invoicing, and our accounts receivable collection. Our contracts with our customers are 
subject to various payment terms and conditions. Our accounts receivable at December 31, 2023, included 
invoices for work performed for a certain Canadian project that remained outstanding which a settlement 
agreement has been reached, subject to meeting certain conditions/terms precedent (See discussion under 
“Known Trends and Uncertainties - Perma-Fix Canada Inc. (“PF Canada”)” below for a discussion of the 
accounts receivable and a partial payment made by the customer on January 22, 2024).  

Prepaid and  other assets  totaled  $3,738,000  as  of  December  31,  2023,  a  decrease  of  $1,667,000 from  the 
December  31,  2022,  balance  of  $5,405,000.  The  decrease  was  primarily  due  to  receipt  of  the  ERC  of 
$1,975,000 in March 2023 that we applied for during the third quarter of 2022. 

Accounts payable totaled $9,582,000 as of December 31, 2023, a decrease of $743,000 from the December 
31, 2022, balance of $10,325,000. Our accounts payable are impacted by the timing of payments as we are 
continually  managing  payment  terms  with  our  vendors  to  maximize  our  cash  position  throughout  our 
segments. 

Accrued  expenses  totaled  $6,560,000  as  of  December  31,  2023,  an  increase  of  $1,967,000  from  the 
December 31, 2022, balance of $4,593,000. The increase was primarily due to higher employee incentive 
and commission accruals totaling approximately $1,346,000. Our employee incentive accruals included an 
aggregate of approximately $750,000 recorded under our 2023 Management Incentive Plans (“MIPs”) for 
our executives.  

We had working capital of $4,613,000 (which included working capital of our discontinued operations) as 
of  December  31,  2023,  as  compared  to  working  capital  of  $818,000  as  of  December  31,  2022.  The 
improvement  in  our  working  capital  was  primarily  due  to  increases  in  our  cash  and  unbilled  receivables 
from improved operations. In 2023, our cash was also increased from the receipt of the ERC in March 2023 
and the additional Term Loan 2 dated July 31, 2023, that we entered into with our lender under our Loan 
Agreement  (see  a  discussion  of  the  Term  Loan  2  below  under  “Financing  Activities).  The  overall 
improvement  in  our  working  capital  was  offset  by  the  increases  in  our  accrued  expenses  and  deferred 
revenues.  

See discussion of a multi-year contract valued up to approximately EUR 50 million awarded to us and our 
JV partner by the European Commission on December 18, 2023, for the treatment of radioactive waste from 
the Joint Research Center in Ispra, Italy under “Business Environment” within this MD&A.  

Investing Activities 
During 2023, our purchases of capital equipment totaled approximately $2,498,000, of which $784,000 was 
subject to financing, with the remaining funded from cash from operations and our credit facility. We have 
budgeted approximately $2,000,000 for 2024 capital expenditures primarily for our Treatment and Services 
Segments  to  maintain  operations  and  regulatory  compliance  requirements  and  support  revenue  growth. 
Certain of these budgeted projects may either be delayed until later years or deferred altogether. We plan to 
fund  our  capital  expenditures  from  cash  from  operations,  collections  of  unpaid  receivables,  borrowing 
availability  under  our  credit  facility  and/or  financing.  The  initiation  and  timing  of  projects  are  also 
determined by financing alternatives or funds available for such capital projects.   

During  March  2022,  we  signed  a  non-binding  joint  venture  term  sheet  addressing  plans  to  partner  with 
Springfields  Fuels  Limited  (“SFL”), an  affiliate  of Westinghouse  Electric  Company  LLC, to  develop  and 
manage a nuclear waste-materials treatment facility (the “Facility”) in the United Kingdom. The Facility is 
for the purpose of expanding the partners’ waste treatment capabilities for the European nuclear market. It is 
expected that upon finalization of a partnership agreement, SFL will have an ownership interest of fifty-five 
(55) percent and our interest will be forty-five (45) percent. The finalization, form and capitalization of this 
unpopulated  partnership  is  subject  to  numerous  conditions,  including  but  not  limited  to,  completion  and 
execution of a definitive agreement and facility design, granting of required regulatory, lender or permitting 
25 

 
 
 
 
 
 
 
 
approvals  and  updated  cost  and  profitability  analysis  based  on  current  and  forecast  future  economic 
conditions. Upon finalization of this venture, we will be required to make an investment in this venture. The 
amount  of  our  investment,  the  period  of  which  it  is  to  be  made  and  the  method  of  funding  are  to  be 
determined. 

Financing Activities 
We entered into a Second Amended and Restated Revolving Credit, Term Loan and Security Agreement, 
dated May 8, 2020 (“Loan Agreement”), with PNC National Association (“PNC” and “lender”), acting as 
agent  and lender.  The  Loan  Agreement,  as amended (including  the two amendments  that  we entered into 
with our lender in 2023 described below), provides us with the following credit facility with a maturity date 
of May 15, 2027: (a) up to $12,500,000 revolving credit (“revolving credit”), with the maximum that we can 
borrow under the revolving credit based on a percentage of eligible receivables (as defined) at any one time 
reduced by outstanding standby letters of credit and borrowing reductions that our lender may impose from 
time to time; (b) a term loan (“Term Loan 1”) dated May 8, 2020, of approximately $1,742,000, requiring 
monthly  installments  of  $35,547;  (c)  a  term  loan  (“Term  Loan  2”)  of  $2,500,000  dated  July  31,  2023, 
requiring  monthly  installments  of  $41,667;  and  (d)  a  capital  expenditure  line  (“Capital  Line”)  of  up  to 
$1,000,000  with  advances  on  the  line,  subject  to  certain  limitations,  permitted  for  up  to  twelve  months 
starting  May  4,  2021  (the  “Borrowing  Period”),  with  interest  only  payable  on  advances  during  the 
Borrowing  Period.  Amounts  advanced  under  the  Capital  Line  at  the  end  of  the  Borrowing  Period  totaled 
approximately $524,000, requiring monthly installments of principal of approximately $8,700 plus interest, 
commencing June 1, 2022.  

On March 21, 2023, we entered into an amendment to our Loan Agreement, as amended, with our lender 
which provided, among other things, the following: 

 

 

 

 

removed  the  quarterly  fixed  charge  coverage  ratio  (“FCCR”)  testing  requirement  for  the  fourth 
quarter of 2022 and removed the FCCR testing requirement for the first quarter of 2023; 
reduced  the  maximum  revolving  credit  line  under  the  credit  facility  from  $18,000,000  to 
$12,500,000; 
reinstated  the  quarterly  FCCR  testing  requirement  starting  in  the  second  quarter  of  2023  using  a 
trailing  twelve-months  period  (with  no  change  to  the  minimum  1.15:1  ratio  requirement  for  each 
quarter); and  
required  maintenance  of  a  minimum  of  $3,000,000  in  borrowing  availability  under  the  revolving 
credit until the minimum FCCR requirement for the quarter ended June 30, 2023 has been met and 
certified  to  the  lender  (we  met  our  FCCR  requirement  in  the  second  quarter  of  2023  which  was 
certified  to  our  lender  and  therefore,  this  requirement  is  no  longer  applicable  under  our  Loan 
Agreement, as amended).  

In  connection  with  the  March  2023  amendment,  we  paid  our  lender  a  fee  of  $25,000  which  is  being 
amortized over the remaining term of the Loan Agreement, as amended, as interest expense-financing fees. 

On  July  31,  2023,  we  entered  into  a  further  amendment  of  the  Loan  Agreement,  as  amended,  with  our 
lender which provided, among other things, the following:   

 

 

 

extended  the maturity  date  of  the  Loan  Agreement,  as  amended, to  May  15,  2027,  from May  15, 
2024; 
an  additional  term  loan  (“Term  Loan  2”)  to  us  in  the  amount  of  $2,500,000,  requiring  monthly 
installments of approximately $41,667. The annual rate of interest due on Term Loan 2 is at prime 
(8.50%  at  December  31,  2023)  plus  3.00%  or  Secured  Overnight  Finance  Rate  (“SOFR”)  (as 
defined in the Loan Agreement, as amended) plus 4.00% plus an SOFR Adjustment applicable for 
an interest period selected by us. A SOFR Adjustment rate of 0.10% and 0.15% is applicable for a 
one-month interest period and three-month period, respectively, that may be selected by us; 
removed  the  minimum  Tangible  Adjusted  Net  Worth  (as  defined  in  the  Loan  Agreement,  as 
amended) covenant requirement; 

  placed an indefinite reduction in borrowing availability of $750,000; and 
 

allows  for  up  to  $2,500,000  in  capital  expenditure  made  in  fiscal  year  2023  and  thereafter  to  be 

26 

 
 
 
 
 
 
treated  as  financed  capital  expenditure  in  the  Company’s  quarterly  FCCR  covenant  calculation 
requirement.  

At  maturity  of  the  Loan  Agreement,  as  amended,  any  unpaid  principal  balance  plus  interest,  if  any,  will 
become due. 

Pursuant  to  the  amendment  dated  July  31,  2023,  we  have  agreed  to  pay  PNC  1.0%  of  the  total  financing 
under the Loan Agreement, as amended, in the event we pay off our obligations on or before July 31, 2024, 
and 0.5% of the total financing if we pay off our obligations after July 31, 2024, to and including July 31, 
2025. No early termination fee shall apply if we pay off our obligations under the amended Loan Agreement 
after July 31, 2025. 

In connection with amendment dated July 31, 2023, we paid our lender a fee of $100,000 which is being 
amortized over the remaining term of the Loan Agreement, as amended, as interest expense-financing fees.  

Pursuant to the  Loan  Agreement, as amended,  the  annual rate of interest  due  on  the  revolving  credit is  at 
prime plus 2% or SOFR plus 3.00% plus an SOFR Adjustment applicable for an interest period selected by 
us. The annual rate of interest due on Term Loan 1 and the Capital line is at prime plus 2.50% or SOFR plus 
3.50% plus an SOFR Adjustment applicable for an interest period selected by us. 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 us. See payment of annual rate of interest due on Term Loan 2 under the amendment 
dated July 31, 2023, as discussed above. 

Our credit facility under our Loan Agreement, as amended, contains certain financial covenants, along with 
customary representations and warranties. A breach of any of these financial covenants, unless waived by 
our lender, 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  the  FCCR  requirement  in  the  first  quarter  of  2023 
pursuant to the March 21, 2023, amendment as discussed above. We otherwise met all of our other financial 
covenant requirements. We met all of our covenant requirements in each of the second to fourth quarters of 
2023 and we expect to meet our covenant requirements in the next twelve months.  

On May 19, 2023, we filed a shelf registration statement on Form S-3 with the U.S Securities and Exchange 
Commission (the “Commission”), which was declared effective by the Commission on June 1, 2023. The 
shelf registration statement gives us the ability to sell up to 2,500,000 shares of our Common Stock from 
time to time and through one or more methods of distribution, subject to market conditions and our capital 
needs at that time. The terms of any offering under the registration statement will be established at the time 
of  the  offering  and  be  set  forth  in  an  accompanying  prospectus  or  prospectus  supplement  relating  to  the 
offering. At this time, we do not have any immediate plans or current commitments to issue shares under the 
registration statement. This is not an offer to sell or a solicitation of an offer to buy, nor shall there be a sale 
of securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to 
registration or qualification under the securities laws of such state or jurisdiction. 

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. At December 31, 2023, the total 
amount  of  standby  letters of  credit  outstanding totaled  approximately  $3,950,000  and  the total  amount  of 
bonds  outstanding  totaled  approximately  $36,674,000.  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”).  At  December  31,  2023,  the  closure  and  post-closure 
requirements for these facilities were approximately $22,461,000. 

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 
27 

 
 
 
 
 
 
 
 
 
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 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 estimated based upon the estimated cost to complete the overall project. 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. 

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. 
If the fair value of the asset is less than the carrying amount, we perform a quantitative test to determine the 
fair 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, 2023, and 2022 
resulted in no impairment charges.  

Intangible  assets  that  have  definite  useful  lives  are  amortized  using  the  straight-line  method  over  the 
estimated  useful  lives  (with  the  exception  of  customer  relationships  which  are  amortized  using  an 
accelerated method) and  are  excluded from  our  annual  intangible  asset  valuation  review  as  of  October  1. 
Intangible  assets  with  definite  useful  lives  are  also  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 
28 

 
 
 
 
 
 
 
 
 
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 
pronouncements that will be adopted in future periods. 

Known Trends and Uncertainties  
Economic  Conditions.  Our  business  continues  to  be  heavily  dependent  on  services  that  we  provide  to 
governmental  clients  (domestic),  primarily  as  subcontractors  for  others  who  are  prime  contractors  to 
government  authorities  (particularly  the  DOE  and  DOD)  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,  the  economic  conditions  and  the  manner  in  which  the  government 
entity  will  be  required  to  spend  funding  to  remediate  various  sites.  In  addition,  our  U.S.  governmental 
contracts and subcontracts relating to activities at governmental sites are generally subject to termination for 
convenience at any time at the option of the government. 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.   

Significant  Customers.  Our  Treatment  and  Services  Segments  have  significant  relationships  with  the  U.S 
governmental  authorities  through  contracts  entered  into  indirectly  as  subcontractors  for  others  who  are 
29 

 
 
 
 
 
 
prime  contractors  or  directly  as  the  prime  contractor  to  government  authorities.  Our  inability  to  continue 
under existing contracts that we have with the U.S 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. 

We  performed  services  relating  to  waste  generated  by  government  clients  (domestic),  either  directly  as  a 
prime  contractor  or  indirectly  for  others  as  a  subcontractor  to  government  entities,  representing 
approximately  $70,642,000,  or  78.7%,  of  our  total  revenue  during  2023,  as  compared  to  $59,658,000,  or 
84.5%, of our total revenue during 2022.  

See discussion of a multi-year contract valued up to approximately EUR 50 million awarded to us and our 
JV partner by the European Commission on December 18, 2023, for the treatment of radioactive waste from 
the Joint Research Center in Ispra, Italy under “Business Environment” within this MD&A.  

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.  

Perma-Fix Canada Inc. (“PF Canada”). During the fourth quarter of 2021, PF Canada received a Notice of 
Termination  (“NOT”)  from  Canadian  Nuclear  Laboratories,  LTD.  (“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. As of 
December  31,  2023,  PF  Canada  has  approximately  $2,389,000  in  unpaid  receivables  due  from  CNL  as  a 
result  of  work  performed  under  the  TOA.  CNL  and  PF  Canada  have  reached  a  settlement  agreement  on 
payment of the receivables to PF Canada by CNL, subject to certain conditions/terms precedents being met, 
including  release  of  certain  liens.  On  January  22,  2024,  we  received  a  partial  payment  of  approximately 
$741,000 from CNL, with the remaining receivables to be paid by CNL upon completion of the settlement 
conditions/terms, which we believe should occur during 2024. 

Potential Partnership with Springfields Fuels Limited. As discussed above, we have signed a non-binding 
term sheet addressing plans to partner with Springfields Fuels Limited, an affiliate of Westinghouse Electric 
Company LLC, to develop and manage a nuclear waste-materials treatment facility in the United Kingdom. 
See  “Liquidity  and  Capital  Resources  –  Investing  Activities”  of  this  MD&A  for  a  discussion  of  this 
transaction. 

Inflation  and  Supply  Chain.  Our  financial  results  have  been  negatively 
impacted  by  various 
macroeconomic factors, including  the  effects  of inflation, supply chain issues, labor shortages, and higher 
interest rates, due, in part, to the impact of COVID-19 (which has mostly subsided). Continued increases in 
any  of  our  operating  costs,  including  utility,  transportation,  wage  rates,  and  supply  costs,  may  further 
increase our overall cost of goods sold or operating expenses. We may attempt to increase our service and 
treatment prices in order to maintain satisfactory margin from the effect of these  factors as discussed above; 
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.

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,  2023  and  2022,  the  related 
consolidated statements of operations, comprehensive income (loss), stockholders’ equity, and cash flows for 
the  years  then  ended,  and  the  related  notes  (collectively  referred  to  as  the  “financial  statements”).  In  our 
opinion, the financial statements present fairly, in all material respects, the financial position of the Company 
as  of  December  31,  2023  and  2022,  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  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our  responsibility  is  to 
express an opinion on the Company’s 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. 

Realizability of deferred tax assets 
As described further in Note 13 to the financial statements, deferred tax assets are reduced by a valuation 
allowance if, based on the evaluation of positive and negative evidence, in management’s judgement it is 
more likely than not that some portion or all, of the deferred tax assets will not be realized. During the year 
ended  December  31,  2023,  management  concluded  that  sufficient  positive  evidence  exists  to  ensure  the 
realizability of the net deferred tax assets that are recorded on the balance sheet.  

The  principal  consideration  for  our  determination  that  the  realizability  of  the  net  deferred  tax  assets  is  a 
critical audit matter is that the projected financial information related to the profitability of the Company, 
which  is  primarily  reliant  on  the  ability  to  predict  future  revenue,  subject  to  significant  management 

34 

 
 
 
 
 
 
 
judgement in determining whether the net deferred tax assets are more likely than not to be realized in the 
future.  This,  in  turn,  led  to  a  high  degree  of  auditor  judgement  and  effort  in  performing  procedures  and 
evaluating  audit  evidence  related  to  management’s  assessment  of  the  realization  of  the  net  deferred  tax 
assets. 

Our audit procedures related to the realizability of the net deferred tax assets included the following, among 
others. 

  We evaluated the positive and negative evidence available to support management’s assessment of the 

realizability of the net deferred tax assets 

  We tested the completeness and accuracy of the underlying data used in management’s assessment 
  We  evaluated 

the  prospective  financial 

to  future  profitability 

information  related 

including 

consideration of: 

o  The current and past performance of the Company 
o  The consistency with external market and industry data 
o  The consistency with evidence obtained in other areas of the audit

Notes to Consolidated Financial Statements 
December 31, 2023, and 2022 

NOTE 1 
DESCRIPTION OF BUSINESS AND BASIS OF PRESENTATION 

Perma-Fix  Environmental  Services,  Inc.    (the  Company,  which  may  be  referred  to  as  we,  us,  or  our),  an 
environmental  and  technology  know-how  company,  is  a  Delaware  corporation,  engaged  through  its 
subsidiaries, in two reportable segments: 

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 

o 

installations using advanced methods, technology and engineering; 
integrated  Occupational  Safety  and  Health  services  including  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  OSHA 
citation assistance; 

o  global  technical  services  providing  consulting,  engineering,  project  management,  waste 
management,  environmental,  and  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. 

-  Nuclear services, which include: 

o 

o 

technology-based services including engineering, D&D, specialty services and construction, 
logistics, transportation, processing and disposal; 
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 NEOSH instrumentation. 

The  Company’s  continuing  operations  consist  of  the  operations  of  our  subsidiaries/facilities  as  follow: 
Diversified Scientific Services, Inc. (“DSSI”), Perma-Fix of Florida, Inc. (“PFF”), Perma-Fix of Northwest 
Richland,  Inc.  (“PFNWR”),  Safety  &  Ecology  Corporation  (“SEC”),  Perma-Fix  Environmental  Services 
UK  Limited  (“PF  UK  Limited”),  Perma-Fix  Canada,  Inc.  (“PF  Canada”)  and  Oak  Ridge  Environmental 
Waste Operations Center (“EWOC”).   

The Company’s continuing operations also consisted of Perma-Fix ERRG, a variable interest entity (“VIE”) 
for  which  we  were  the  primary  beneficiary.  The  VIE  was  an  unpopulated  joint  venture  (“JV”)  entered 
between the Company and Engineering/Remediation Resources Group, Inc. (“ERRG”) for a specific project 
under the Services Segment in which the Company and ERRG had a 51% and 49% partnership interest in 
the joint venture, respectively.  During the fourth quarter of 2022, project work under the JV was completed  

The Company’s discontinued operations (see “Note 8 – Discontinued Operations”) consist of operations of 
all our subsidiaries included in our Industrial Segment which encompasses subsidiaries divested in 2011 and 

42 

 
 
 
 
 
 
 
 
earlier, as well as three previously closed locations.     

On December 18, 2023, a JV where the Company and Campoverde Srl (“JV partner”) each owns 50% of 
the  partnership,  was  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. Work under this JV has not started as of December 31, 2023. The scope of 
work  to  be  performed  in  the  initial  phases  of  this  contract  will  be  performed  predominately  by  our  JV 
partner. Revenue generated by the Company under the initial phases will be limited to project management 
support through 2025. The Company expects 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. Once activities commence under this JV, the Company 
will consolidate the operations of this JV into its financial statements. 

Financial Positions and Liquidity 
The Company experienced significant improvement in its 2023 financial results as the lingering effects of 
COVID-19  began  to  subside  starting  in  the  early  part  of  2022.  The  Company’s  Treatment  Segment 
continued to see steady improvements in waste receipts from certain customers who had previously delayed 
waste  shipments  due,  in  part,  from  the  impact  of  COVID-19.  Within  the  Company’s  Services  Segment, 
certain projects which were delayed/curtailed in first part of 2022 due, in part, from the lingering effects of 
the  COVID-19,  achieved  full  operational  status  and  improved  productivity  in  2023  which  positively 
impacted  revenue.  Revenues  from  both  of  the  Company’s  Segments  were  also  positively  impacted  from 
contracts  won  in  2023  as  procurement  and  planning  on  behalf  of  our  government  clients  continued  to 
progress as the lingering effects of COVID-19 pandemic subsided.  

Heading into 2024, the Company expects to see overall continue steady improvements in waste receipts and 
increases in project work from certain existing contracts, contracts won in 2023, and bids submitted in both 
segments that are awaiting awards. However, due to our operations which is subject to seasonal factor, the 
Company generally experiences lower revenue in the first quarter due to overall reduced activities by our 
customers from the usual slowdown in operations due, in part, from returning from the holiday periods and 
poorer weather conditions. Additionally, due to Congress’s inability to timely approve FY 2024 budget and 
the extension of the continuing resolution, certain of our government related customers have informed us 
that waste shipments will likely be delayed. Although the Company expects to see overall improvements in 
revenue in 2024 as disclosed above, if Congress is unable to enact the full FY 2024 appropriation bills or 
further extend the continuing resolutions to fund government spending by the late March deadline, the U.S. 
government  will  enter  into  a  partial  shutdown.  The  full  impact  of  any  additional  continued  resolution 
beyond  March  or  a  partial  government  shutdown  is  uncertain.  If  a  partial  government  shutdown  were  to 
occur  and  were  to  continue  an  extended  period,  our  financial  results  of  operations  could  be  negatively 
impacted by delays in procurement actions, waste shipments and project delays on newly awarded projects. 

The  Company’s  cash  flow  requirements  during  the  twelve-months  ended  December  31,  2023,  were 
primarily financed by its operations, credit facility availability and cash on hand (which included the ERC, 
along with interest, that the Company received in March 2023 (See “Note 10 – Employee Retention Credit 
(“ERC”) and proceeds from a new term loan dated July 31, 2023, in the amount of $2,500,000 provided to 
us under an amendment to the Company’s existing credit facility (See “Note 9 – Long Term Debt”)). The 
Company’s  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,  and  planned 
capital  expenditures.  The  Company  plans  to  fund  these  requirements  from  its  operations,  cash  on  hand, 
credit  facility  availability,  and  collections  of  unpaid  receivables  (See  “Note  14  –  Commitments  and 
Contingencies - Perma-Fix Canada, Inc. (“PF Canada”)” and “Note 19 – Subsequent Events – Perma-Fix 
Canada, Inc. (“PF Canada”)” for a discussion of a settlement agreement relating to unpaid receivables due 
to the Company from Canadian Nuclear Laboratories (“CNL”)). The Company’s ability to utilize its credit 
facility  from  its  lender  is  subject  to  meeting  its  quarterly  financial  covenant  requirements,  among  other 
things.  The  Company  continues  to  explore  all  sources  of  increasing  its  capital  and/or  liquidity  and  to 
improve  its  revenue  and  working  capital,  including,  but  not  limited  to  entering  into  equity  transactions. 
There are no assurances that the Company will be successful in increasing our liquidity through our efforts. 
The  Company  is  continually  reviewing  operating  costs  and  reviewing  the  possibility  of  further  reducing 
43 

 
 
 
 
 
operating costs and non-essential expenditures to bring them in line with revenue levels, when necessary. At 
this time, the Company believes that its cash flows from operations, our available liquidity from our credit 
facility, and our cash on hand should be sufficient to fund our operations for the next twelve months.  

NOTE 2 
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES 

Principles of Consolidation 
The  Company’s  consolidated  financial  statements  include  our  accounts  and  those  of  our  wholly-owned 
subsidiaries.  The  Company’s  consolidated  financial  statements  for  2022  also  included  the  accounts  of 
Perma-Fix ERRG, a VIE for which we were the primary beneficiary as discussed above, after elimination of 
all significant intercompany accounts and transactions.  

Use of Estimates 
The Company prepares financial statements in conformity with accounting standards generally accepted in 
the United States (“U.S. GAAP”), which may require estimates of future cash flows and assumptions that 
affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the 
date  of  the  financial  statements,  as  well  as  the  reported  amounts  of  revenues  and  expenses  during  the 
reporting period. Due to the inherent uncertainty involved in making estimates, actual results could differ 
from those estimates.  

Cash and Finite Risk Sinking Fund (Restricted Cash) 
As  of  December  31,  2023,  and  2022,  the  Company  had  cash  on  hand  of  approximately  $7,500,000  and 
$1,866,000, respectively. Starting in late 2023, the Company maintained an interest bearing money account 
with  its  lender.  At  December  31,  2023,  and  2022,  the  Company  had  finite  risk  sinking  funds  of 
approximately $12,074,000 and $11,570,000, respectively, which represented cash held as collateral under 
the Company’s financial assurance policy (see “Note 14 – Commitment and Contingencies – Insurance” for 
a discussion of this finite risk sinking fund). 

Accounts Receivable 
Accounts  receivable  are  customer  obligations  due  under  normal  trade  terms  generally  requiring  payment 
within  30  or  60  days  from  the  invoice  date  based  on  the  customer  type  (government,  broker,  or 
commercial).  The  carrying  amount  of  accounts  receivables  is  reduced  by  a  credit  loss  determined  in 
accordance with Accounting Standards Update (“ASU”) 2016-13 “Credit Losses (Topic 326) Measurement 
of  Credit  Losses  on  Financial  Instruments.”  which  requires  the  Company  to  consider  forward-looking 
information in estimating the expected loss and is developed using historical collection experience, current 
and future economic and market conditions that may affect customers’ ability to pay, and a review of the 
current status of customers’ accounts receivables. The Company does not apply a credit loss allowance to 
government related receivables due to our past successful experience in their collectability. The Company’s 
monitoring  activities  include  routine  follow-up  on  past  due  accounts  and  consideration  of  customers’ 
financial conditions. Once the Company has exhausted all options in the collection of a delinquent accounts 
receivable  balance,  which  includes  collection  letters,  demands  for  payment,  collection  agencies  and 
attorneys, the account is deemed uncollectible and subsequently written off. The write off process involves 
approvals from senior management based on required approval thresholds.  

The following table sets forth the activity in the allowance for credit losses for the years ended December 
31, 2023, and 2022 (in thousands):

Unbilled Receivables 
Unbilled  receivables  are  generated  by  differences  between  invoicing  timing  and  our  over  time  revenue 
recognition  methodology  used  for  revenue  recognition  purposes.  As  major  processing  and  contract 
completion  phases  are  completed  and  the  costs  are  incurred,  the  Company  recognizes  the  corresponding 
percentage  of  revenue.  Within  our  Treatment  Segment,  the  facilities  experience  delays  in  processing 
invoices due to the complexity of the documentation that is required for invoicing, as well as the difference 
between  completion  of revenue recognition milestones  and  agreed  upon invoicing  terms,  which results in 
unbilled  receivables.  The  timing  differences  occur  for  several  reasons  which  include:  delays  in  the  final 
processing of all wastes associated with certain work orders and delays for analytical testing that is required 
after the facilities have processed waste but prior to our release of waste for disposal. The tasks relating to 
these delays can take months to complete but are generally completed within twelve months.  

Unbilled  receivables  within  our  Services  Segment  can  result  from  work  performed  under  contracts  but 
invoice  milestones  have  not  yet  been  met  and/or  contract  claims  and  pending  change  orders,  including 
requests for equitable adjustments (“REA”) for which work has been performed and collection of revenue is 
reasonably assured.   

Inventories 
Inventories  consist  of  treatment  chemicals,  saleable  used  oils,  and  certain  supplies.  Additionally,  the 
Company has replacement parts in inventory, which are deemed critical to the operating equipment and may 
also  have  extended  lead  times  should  the  part  fail  and  need  to  be  replaced.  Inventories  are  valued  at  the 
lower of cost or net realizable value with cost determined by the first-in, first-out method. 

Disposal and Transportation Costs 
The Company accrues for waste disposal based on the waste at each facility at the end of each accounting 
period.  Current market  prices for transportation and disposal  costs  are  applied to  the  end of  period  waste 
inventories to calculate for the transportation and disposal accruals.  

Property and Equipment  
Property and equipment expenditures are capitalized and depreciated using the straight-line method over the 
estimated useful lives of the assets for financial statement purposes, while accelerated depreciation methods 
are  principally  used  for  income  tax  purposes.  Generally,  asset  lives  range  from  ten  to  forty  years  for 
buildings (including improvements and asset retirement costs) and three to seven years for office furniture 
and  equipment,  vehicles,  and  decontamination  and  processing  equipment.  Leasehold  improvements  are 
capitalized and amortized over the lesser of the term of the lease or the life of the asset. Maintenance and 
repairs are charged directly to expense as incurred. The cost and accumulated depreciation of assets sold or 
retired are removed from the respective accounts, and any gain or loss from sale or retirement is recognized 
in  the  accompanying  Consolidated  Statements  of  Operations.  Renewals  and  improvements,  which  extend 
the useful lives of the assets, are capitalized.  

Certain property and equipment expenditures are financed through leases. Amortization of financed leased 
assets  is  computed  using  the  straight-line  method  over  the  estimated  useful  lives  of  the  assets.  As  of 
December 31, 2023, assets recorded under finance leases were $1,608,000 less accumulated depreciation of 
$545,000, resulting in net fixed assets under finance leases of $1,063,000. As of December 31, 2022, assets 
recorded under finance leases were $1,201,000 less accumulated depreciation of $549,000, resulting in net 
fixed assets under finance leases of $652,000. These assets are recorded within net property and equipment 
on the Consolidated Balance Sheets.  

Long-lived assets, such as property, plant and equipment, are reviewed for impairment whenever events or 
changes  in  circumstances  indicate  that  the  carrying  amount  of  an  asset  may  not  be  recoverable. 
Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset 
to estimated undiscounted future cash flows expected to be generated by the asset.  If the carrying amount of 
an asset exceeds its estimated future cash flows, an impairment charge is recognized in the amount by which 
the carrying amount of the asset exceeds the fair value of the asset. Assets to be disposed of are separately 
presented in the balance sheet and reported at the lower of the carrying amount or fair value less costs to sell 
and are no longer depreciated.  

45 

 
 
 
 
 
 
 
Our depreciation expense totaled approximately $2,370,000 and $1,872,000 in 2023 and 2022, respectively. 

Leases 
The Company accounts for leases in accordance with FASB’s ASU 2016-02, “Leases (Topic 842).” 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. The Company’s operating leases also 
include  the  lease  of  a  building  with  land  utilized  for  our  waste  treatment  operations  which  includes  a 
purchase  option.  These  leases  have  remaining  terms  of  approximately  one  to  six  years.    The  Company 
includes renewal options in valuing its ROU assets and liabilities when it determines that it is reasonably 
certain to exercise these renewal options; however, at December 31, 2023, none of our operating leases has 
remaining renewal options. As most of our operating leases do not provide an implicit rate, the Company 
uses  its  incremental  borrowing  rate  as  the  discount  rate  when  determining  the  present  value  of  the  lease 
payments. The incremental borrowing rate is determined based on the Company’s secured borrowing rate, 
lease  terms  and  current  economic  environment.  Some  of  our  operating  leases  include  both  lease  (rent 
payments) and non-lease components (maintenance costs such as cleaning and landscaping services). The 
Company has elected the practical expedient to account for lease component and non-lease component as a 
single component for all leases under ASU 2016-02. Lease expense for operating leases is recognized on a 
straight-line basis over the lease term.  

Finance  leases  primarily  consist  of  processing  and  transport  equipment  used  by  our  facilities’  operations. 
The Company’s finance leases have remaining terms of approximately one to six years. See “Property and 
Equipment”  above  for  assets  recorded  under  financed  leases.  Borrowing  rates  for  our  finance  leases  are 
either  explicitly  stated  in  the  lease  agreements  or implicitly  determined  from  available  terms  in  the  lease 
agreements. 

The Company adopted the policy to not recognize ROU assets and liabilities for short term leases.  

Intangible Assets 
Intangible assets consist primarily of the recognized value of the permits required to operate our business. 
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. 
If the fair value of the asset is less than the carrying amount, a quantitative test is performed to determine 
the fair value. The impairment loss, if any, is measured as the excess of the carrying value of the asset over 
its fair value. Judgments and estimates 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 
indefinite-lived permits related to our Treatment reporting unit as of October 1, 2023 and 2022 resulted in 
no impairment charges. 

Intangible  assets  that  have  definite  useful  lives  are  amortized  using  the  straight-line  method  over  the 
estimated  useful  lives  (with  the  exception  of  customer  relationships  which  are  amortized  using  an 
accelerated method) and  are  excluded from  our  annual  intangible  asset  valuation  review  as  of  October  1. 
Definite-lived intangible assets are also tested for impairment whenever events or changes in circumstances 
suggest impairment might exist.  

Research and Development (“R&D”) 
Operational innovation and technical know-how are 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  and  to  develop  new  company  service  offerings.  The  Company  conducts  research 
internally and also through collaborations with other third parties. R&D costs consist primarily of employee 
salaries  and  benefits,  laboratory  costs,  third  party  fees,  and  other  related  costs  associated  with  the 
development  and  enhancement  of  new  potential  waste  treatment  processes  and  new  technology  and  are 
46 

 
 
 
 
 
 
 
 
charged to expense when incurred in accordance with ASC Topic 730, “Research and Development.”  

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.  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, the Company 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  flows.  Increases  in  the  ARO  liability  due  to  passage  of  time  impact  net  income  as 
accretion  expense,  which  is  included  in  cost  of  goods  sold.  Changes  in  costs  resulting  from  changes  or 
expansion  at  the  facilities  require  adjustment  to  the  ARO  liability  and  are  capitalized  and  charged  as 
depreciation expense, in accordance with the Company’s depreciation policy.  

Income Taxes 
Income  taxes  are  accounted  for  in  accordance  with  ASC  740,  “Income  Taxes.”  Under  ASC  740,  the 
provision for income taxes is comprised of taxes that are currently payable and deferred taxes that relate to 
the temporary differences between financial reporting carrying values and tax bases of assets and liabilities. 
Deferred tax assets and liabilities are measured using enacted income tax rates expected to apply to taxable 
income in the years in which those temporary differences are expected to be recovered or settled. Any effect 
on  deferred  tax  assets  and  liabilities  of  a  change  in  tax  rates  is  recognized  in  income  in  the  period  that 
includes the enactment date. 

ASC 740 requires that deferred income tax assets be reduced by a valuation allowance if it is more likely 
than  not  that  some  portion  or  all  of  the  deferred  income  tax  assets  will  not  be  realized.  The  Company 
regularly assesses the likelihood that the deferred tax asset will be recovered from future taxable income. 
The Company considers projected future taxable income and ongoing tax planning strategies, then records a 
valuation allowance to reduce the carrying value of the net deferred income taxes to an amount that is more 
likely than not to be realized.  

ASC 740 sets out a consistent framework for preparers to use to determine the appropriate recognition and 
measurement  of  uncertain  tax  positions.  ASC  740  uses  a  two-step  approach  wherein  a  tax  benefit  is 
recognized if a position is more-likely-than-not to be sustained. The amount of the benefit is then measured 
to  be  the  highest  tax  benefit  which  is  greater  than  50%  likely  to  be  realized.  ASC  740  also  sets  out 
disclosure  requirements  to  enhance  transparency  of  an  entity’s  tax  reserves.  The  Company  recognizes 
accrued interest and income tax penalties related to unrecognized tax benefits as a component of income tax 
expense. 

The  Company  reassesses  the  validity  of  our  conclusions  regarding  uncertain  income  tax  positions  on  a 
quarterly  basis  to  determine  if  facts  or  circumstances  have  arisen  that  might  cause  us  to  change  our 
judgment regarding the likelihood of a tax position’s sustainability under audit.  

Foreign Currency 
The  Company’s  foreign  subsidiaries  include  PF  UK  Limited  and  PF  Canada.  Assets  and  liabilities  are 
translated to U.S. dollars at the exchange rate in effect at the balance sheet date and revenue and expenses at 
the average exchange rate for the period. Foreign currency translation adjustments for these subsidiaries are 
accumulated as a separate component of accumulated other comprehensive income (loss) in stockholders’ 
equity.  Gains  and  losses  resulting  from  foreign  currency  transactions  are  recognized  in  the  Consolidated 
Statements of Operations.   

47 

 
 
 
 
 
 
 
 
Concentration Risk 
The  Company  performed  services  relating  to  waste  generated  by  government  clients  (domestic),  either 
indirectly for others as a subcontractor to government entities or directly as a prime contractor, representing 
approximately  $70,642,000,  or  78.8%,  of  our  total  revenue  during  2023,  as  compared  to  $59,658,000,  or 
84.5%, of our total revenue during 2022.  

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. 

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist 
principally  of  cash  and  accounts  receivable.  The  Company  maintains  cash  with  high  quality  financial 
institutions, which may exceed Federal Deposit Insurance Corporation (“FDIC”) insured amounts from time 
to  time.  The  Company  has  not  experienced  any  losses  due  to  such  cash  concentration.  Concentration  of 
credit risk with respect to accounts receivable is limited due to the Company's large number of customers 
and  their  dispersion  throughout  the  United  States  as  well  as  with  the  significant  amount  of  work  that  we 
perform for government entities. 

The Company had two government related customers whose total unbilled and net outstanding receivable 
balances each represented 13.2% of the Company’s total consolidated unbilled and net accounts receivable 
at December 31, 2023. The Company had two government related customers whose total unbilled and net 
outstanding receivable balances represented 12.5% and 23.0% of the Company’s total consolidated unbilled 
and net accounts receivable at December 31, 2022. 

Revenue Recognition and Related Policies 
The  Company  recognizes  revenue  in  accordance  with  FASB’s  ASC  606,  “Revenue  from  Contracts  with 
Customers.”  ASC  606  provides a  single,  comprehensive  revenue  recognition model for  all contracts  with 
customers.  Under  ASC  606,  a  five-step  process  is  utilized  in  order  to  determine  revenue  recognition, 
depicting  the  transfer  of  goods  or  services  to  a  customer  at  an  amount  that  reflects  the  consideration  it 
expects to receive in exchange for those goods or services. Under ASC 606, a performance obligation is a 
promise  in  a  contract  to  transfer  a  distinct  good  or  service  to  the  customer  and  is  the  unit  of  account.  A 
contract transaction price is allocated to each distinct performance obligation and recognized as revenues as 
the performance obligation is satisfied.  

Treatment Segment Revenues: 
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. 
Performance obligations are generally satisfied over time using the input method.  Under the input method, 
the  Company  uses  a  measure  of  progress  divided  into  major  phases  which  include  receipt  (ranging  from 
9.0% to 33%), treatment/processing (ranging from 40% to 87%) and shipment/final disposal (ranging from 
2.0%  to  27%).  As  major  processing  phases  are  completed  and  the  costs  are  incurred,  the  proportional 
percentage of revenue is recognized. Transaction price for Treatment Segment contracts are determined by 
the stated fixed rate per unit price as stipulated in the contract. 

The Company 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 the Company.    

Services Segment Revenues: 
Revenues for our Services Segment are generated from time and materials or fixed price arrangements: 

The Company’s primary obligation to customers in time and materials contracts relate to the provision of 
services to the customer at the direction of the customer.  This provision of services at the request of the 
customer  is  the  performance  obligation,  which  is  satisfied  over  time.  Revenue  earned  from  time  and 
materials contracts is determined using the input method and is based on contractually defined billing rates 
applied to services performed and materials delivered.  

48 

 
 
 
 
 
 
 
 
 
 
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 estimated based upon the estimated cost to complete the overall 
project. 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. 

As  discussed  above  for  the  Treatment  and  Services  Segments,  the  Company’  revenue  is  generally 
recognized using the input method. This method of measuring progress provides a faithful depiction of the 
transfer to goods and services because the costs incurred are expected to be substantially proportionate to 
the Company’s satisfaction of the performance obligation.  

Contracts  with  our  customers  within  our  Treatment  Segment  are  generally  short  term  with  an  original 
expected length of one year or less. For the Services Segment, contracts with our customers generally have 
original  terms  ranging  from  one  year  or  less  to  approximately  twenty-four  months.  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.  

Variable Consideration 
The Company’s contracts generally do not give rise to variable consideration. However, from time to time, 
the Company may submit requests for equitable adjustments under certain of its government contracts for 
price or other modifications that are determined to be variable consideration. The Company estimates 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.   

Significant Payment Terms 
Invoicing is based on schedules established in customer contracts. Payment terms vary by customers but are 
generally established at 30 days from invoicing.   

Incremental Costs to Obtain a Contract 
Costs incurred to obtain contracts with our customers are immaterial and as a result, the Company expenses 
(within  selling,  general  and  administration  expenses  (“SG&A”))  incremental  costs  incurred  in  obtaining 
contracts with our customer as incurred.  

Remaining Performance Obligations 
The Company applies the practical expedient in 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.   

Stock-Based Compensation 
Stock-based  compensation  granted  to  employees  are  accounted  for  in  accordance  with  ASC  718, 
“Compensation – Stock Compensation.” Stock-based payment transactions for acquiring goods and services 
from  nonemployees  are  also  accounted  for  under  ASC  718.  ASC  718  requires  stock-based  payments  to 
49 

 
 
 
 
 
 
  
 
 
 
employees and nonemployees, including grant of options, to be recognized in the Statement of Operations 
based on their fair values. The Company uses the Black-Scholes option-pricing model to determine the fair-
value of stock-based awards which requires subjective assumptions. Assumptions used to estimate the fair 
value  of  stock-based  awards  include  the  exercise  price  of  the  award,  the  expected  term,  the  expected 
volatility  of  our  stock  over  the  stock-based  award’s  expected  term,  the  risk-free  interest  rate  over  the 
award’s expected term, and the expected annual dividend yield. The Company accounts for forfeitures when 
they occur. 

Comprehensive Income (Loss) 
The components of comprehensive income (loss) are net income (loss) and the effects of foreign currency 
translation adjustments.    

Income (Loss) Per Share 
Basic income (loss) per share is calculated based on the weighted-average number of outstanding common 
shares  during  the  applicable  period.  Diluted  income  (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 
earnings per share. Income (loss) per share is computed separately for each period presented.   

Fair Value of Financial Instruments 
Certain assets and liabilities are required to be recorded at fair value on a recurring basis, while other assets 
and  liabilities  are  recorded  at  fair  value  on  a  nonrecurring  basis. Fair  value  is  determined  based  on  the 
exchange  price  that  would  be  received  for  an  asset  or  paid  to  transfer  a  liability  (an  exit  price)  in  the 
principal  or  most  advantageous  market  for  the  asset  or  liability  in  an  orderly  transaction  between  market 
participants. The three-tier value hierarchy, which prioritizes the inputs used in the valuation methodologies, 
is: 

Level 1—Valuations based on quoted prices for identical assets and liabilities in active markets. 
Level 2—Valuations based on observable inputs other than quoted prices included in Level 1, such as 
quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar 
assets  and  liabilities  in  markets  that  are  not  active,  or  other  inputs  that  are  observable  or  can  be 
corroborated by observable market data. 
Level  3—Valuations  based  on  unobservable  inputs  reflecting  the  Company’s  own  assumptions, 
consistent with reasonably available assumptions made by other market participants. 

Financial  instruments  include  cash (Level  1),  accounts  receivable,  accounts  payable, and  debt  obligations 
(Level 3).  Credit is extended to customers based on an evaluation of a customer’s financial condition and, 
generally, collateral is not required. As of December 31, 2023, and December 31, 2022, the fair value of the 
Company’s  financial  instruments  approximated  their  carrying  values. The  fair  value  of  the  Company’s 
revolving credit, term loans and capital loan approximate its carrying value due to the variable interest rate.   

Recently Issued Accounting Standards – Not Yet Adopted 
In  August  2023,  the  FASB  issued  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 Company is currently evaluating the impact of this ASU on its consolidated financial 
statements.  

In  November  2023,  the  FASB  issued ASU  2023-07,  “Segment  Reporting  (Topic  280):  Improvements  to 
Reportable Segment Disclosures,” which expands reportable segment disclosure requirements by requiring 
disclosures  of  significant  reportable  segment  expenses  that  are  regularly  provided  to  the  CODM  and 
included within each reported measure of a segment's profit or loss. The ASU also requires disclosure of the 
title and position of the individual identified as the CODM and an explanation of how the CODM uses the 
reported  measures  of  a  segment's  profit  or  loss  in  assessing  segment  performance  and  deciding  how  to 
allocate resources. Additionally,  ASU 2023-07 requires all segment profit or loss and assets disclosures to 
50 

 
 
 
 
 
 
 
be  provided  on an  annual and  interim  basis. The  amendments  in this  ASU  are required to  be  adopted  for 
fiscal  years  beginning  after  December  15,  2023,  and  interim  periods  within  fiscal  years  beginning  after 
December  15,  2024  with  early  adoption  permitted,  and  should  be  applied  on  a  retrospective  basis.  ASU 
2023-07  will  be  effective  for the  Company’s  financial  statements  for the  year  ended  December  31,  2024. 
This ASU will not have impact on the Company’s consolidated financial condition or results of operations. 
The Company is evaluating the impact to the related segment reporting disclosures.  

In  December  2023,  the  FASB  issued Accounting  Standards  Update  No.  2023-09,  “Income  Taxes  (Topic 
740): Improvements to Income Tax Disclosures” (“ASU 2023-09”), 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. The guidance is effective for annual periods beginning 
after  December  15,  2024.  ASU  2023-09  should  be  applied  on  a  prospective  basis,  but  retrospective 
application is permitted. This ASU will not have impact on the Company’s consolidated financial condition 
or results of operations. The Company is evaluating the impact to its income taxes reporting disclosures.

Contract Balances 
The  timing  of  revenue  recognition  and  billings  results  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  our  performance  obligation.  The  following  table  represents 
changes  in  our  contract  asset  and  contract  liabilities  balances:  Our  deferred  revenue  as  of  December  31, 
2023,  included  a  remaining  prepayment  of  approximately  $2,031,000  by  a  certain  customer  for  a  waste 
treatment project which is expected to be completed in 2024.

NOTE 6 
CAPITAL STOCK, STOCK PLANS, WARRANTS AND STOCK BASED COMPENSATION 

Stock Option Plans 
The Company’s 2003 Outside Directors Stock Plan, as amended (the “2003 Plan”) provides for the grant of 
Non-Qualified Stock Options (“NQSOs”) to member of the Company’s Board of Directors (the “Board”) 
who  is  not  an  employee  of  the  Company  or  its  subsidiaries  (“Eligible  Director”).  The  2003  Plan  also 
provides for the grant of an NQSO to purchase up to 10,000 shares of the Company’s Common Stock for 
each  Eligible  Director  upon  each  re-election  to  the  Board,  and  the  grant  of  an  NQSO  to  purchase  up  to 
20,000 shares of the Company’s Common Stock upon initial election. NQSOs granted prior to July 20, 2021 
have a vesting period of six months from the date of grant and a term of 10 years, with an exercise price 
equal to the closing trade price on the date prior to grant date. NQSOs granted on and after July 20, 2021 
vest 25% per year, beginning on the first anniversary date of the grant and also have a term of 10 years, with 
an exercise price equal to the closing trade price on the date prior to grant date. Additionally, the 2003 Plan 
provides for the issuance to each Eligible Director a number of shares of the Company’s Common Stock in 
lieu of 65% or 100% (based on option elected by each director) of the fee payable to the Eligible Director 
for services rendered as a member of the Board. The number of shares issued is determined at 75% of the 
market  value  as  defined  in  the  plan  (the  Company  recognizes  100%  of  the  market  value  of  the  shares 
issued). At December 31, 2023, the 2003 Plan had available for issuance 318,680 shares. 

The Company’s 2017 Stock Option Plan, as amended (the “2017 Plan”), authorizes the grant of options to 
officers and  employees  of the  Company,  including  any  employee  who is  also  a member  of  the  Board,  as 
well as to consultants of the Company. The 2017 Plan authorizes an aggregate grant of 1,740,000 NQSOs 
and Incentive Stock Options (“ISOs”), which included an increase of 600,000 additional authorized shares 
approved by the Company’s Stockholders at the Company’s 2023 Annual Meeting of Stockholders held on 
July  20,  2023.  Consultants  of  the  Company  can  only  be  granted  NQSOs.  The  term  of  each  stock  option 
granted  under  the  2017  Plan  shall  be  fixed  by  the  Compensation  and  Stock  Option  Committee  (the 
“Compensation Committee”), but no stock options will be exercisable more than ten years after the grant 
date,  or  in  the  case  of  an  ISO  granted  to  a 10%  stockholder, five  years after  the  grant  date.  The exercise 
price of any ISO granted under the 2017 Plan to an individual who is not a 10% stockholder at the time of 
the grant shall not be less than the fair market value of the shares at the time of the grant, and the exercise 
price of any ISO granted to a 10% stockholder shall not be less than 110% of the fair market value at the 
time of grant. The exercise price of any NQSOs granted under the plan shall not be less than the fair market 
value of the shares at the time of grant. At December 31, 2023, the 2017 Plan had available for issuance 
720,500 shares. 

Stock Options to Employees and Outside Director 
On January 19, 2023, the Company granted ISOs to certain employees under the 2017 Plan, for the purchase 
of up to an aggregate 295,000 shares of the Company’s Common Stock. The total ISOs granted included an 
ISO  for  each  of  the  Company’s  executive  officers  for  the  purchase  set  forth  in  his  respective  ISO

Agreement, as follows: 70,000 shares for the Chief Executive Officer (“CEO”); 40,000 shares for the Chief 
Financial Officer (“CFO”); 30,000 shares for the Executive Vice President (“EVP”) of Strategic Initiatives; 
30,000 shares for the EVP of Waste Treatment Operations; and 30,000 shares for the EVP of Nuclear and 
Technical  Services.  Each  of  the  ISOs  granted  has  a  contractual  term  of  six  years  with  one-fifth  yearly 
vesting over a five-year period. The exercise price of each ISO is $3.95 per share, which was equal to the 
fair market value of the Company’s Common Stock on the date of grant.   

On  July  20,  2023, the  Company  issued  a  NQSO  to each  of the  Company’s  seven  reelected  outside  (non-
management)  directors  under  the  2003  Plan,  for  the  purchase  of  up  to  10,000  shares  of  the  Company’s 
Common Stock. The CEO and EVP of Strategic Initiatives, each an executive officer of the Company as 
well as a director, were not eligible to receive an option under the 2003 Plan. Each NQSO granted is for a 
contractual term of ten years with one-fourth vesting annually over a four-year period. The exercise price of 
each NQSO is $9.81 per share, which was equal to the fair market value of the Company’s Common Stock 
on the day preceding the grant date, in accordance with the 2003 Plan.  

On October 19, 2023, the Company granted an ISO to an employee under the 2017 Plan, for the purchase of 
up to 5,000 shares of the Company’s Common Stock. The ISO granted is for a contractual term of six years 
with  one-fifth  vesting  annually  over  a  five-year  period.  The  exercise  price  of  the  ISO  is  $9.62  per  share, 
which was equal to the fair market value of the Company’s Common Stock on the date of grant.  

On July 21, 2022, the Company issued a NQSO to each of the Company’s seven reelected outside directors 
under  the  2003  Plan,  for  the  purchase  of  up  to  10,000  shares  of  the  Company’s  Common  Stock.  The 
Company’s  EVP  of  Strategic  Initiatives  and  also  a  member  of  the  Company’s  Board,  was  not  eligible  to 
receive  an  option  under  the  2003  Plan  as  an  employee  of  the  Company.  Each  NQSO  granted  is  for  a 
contractual term of ten years with one-fourth vesting annually over a four-year period. The exercise price of 
the NQSO is $5.15 per share, which was equal to the fair market value of the Company’s Common Stock 
the day preceding the grant date, pursuant to the 2003 Plan.  

On July 21, 2022, the Company granted ISOs to certain employees under the 2017 Plan, for the purchase of 
up to an aggregate of 24,000 shares of the Company’s Common Stock. Each ISO granted is for a contractual 
term of six years with one-fifth vesting annually over a five-year period. The exercise price of the ISO is 
$5.34 per share, which was equal to the fair market value of the Company’s Common Stock on the date of 
grant.  

During  2023,  the  Company  issued  an  aggregate  185,549  shares  of  its  Common  Stock  from  cashless 
exercises  of  options  for  the  purchases  of  280,000  shares  of  the  Company’s  Common  Stock,  at  exercise 
prices ranging from $3.60 per share to $7.005 per share. Additionally, the Company issued 40,400 shares of 
its Common Stock from the cash exercise of options for the purchase of 40,400 shares of the Company’s 
Common  Stock,  at  exercise  prices  ranging  from  at  $2.785  per  share  to  $7.005  per  share  resulting  in 
proceeds of approximately $164,000. Income tax benefit associated with stock options exercised with cash 
during 2023 was approximately $25,000. 

During 2022, the Company issued 16,526 shares of its Common Stock from a cashless exercise of an option 
for the purchase of 50,000 shares of the Company’s Common Stock at $3.97 per share. Additionally, the 
Company issued 2,400 shares of its Common Stock from the exercise of an option for the purchase of 2,400

The Company estimates fair value of stock options using the Black-Scholes valuation model.  Assumptions 
used to estimate the fair value of stock options granted include the exercise price of the award, the expected 
term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest 
rate over the option’s expected term, and the expected annual dividend yield.  The fair value of the options 
granted during 2023 and 2022 and the related assumptions used in the Black-Scholes option model used to 
value the options granted were as follows:

 (1)  The risk-free interest rate is based on the U.S. Treasury yield in effect at the grant date over the expected term of the option. 

(2)  The expected volatility is based on historical volatility from our traded Common Stock over the expected term of the option. 

(3)  The Company has never paid any dividends on its Common Stock. Our Loan Agreement prohibits the Company from paying any 

cash dividends without prior approval from our lender. 

(4)  The expected option life is based on historical exercises and post-vesting data.

Stock Options to Consultant 
On July 27, 2017, the Company granted a NQSO from the 2017 Plan to Robert Ferguson, for the purchase 
of up to 100,000 shares of the Company’s Common Stock (“Ferguson Stock Option”), at an exercise price 
of $3.65 per share, which was the fair market value of the Company’s Common Stock on the date of grant. 
The  Ferguson  Stock  Option  was  granted  in  connection  with  Mr.  Ferguson’s  work  as  a  consultant  to  the 
Company’s Test Bed Initiative (“TBI”) at our PFNWR facility. The term of the Ferguson Stock Option was 
seven  years  from  the  grant  date,  with  vesting  subject  to  the  achievement  of  three  separate  milestones  by 
certain  dates,  the  achievement  of  which  would  entitle  Mr.  Ferguson  to  purchase,  respectively,  10,000, 
30,000,  and  60,000  shares  of  the  Company’s  Common  Stock  issuable  under  the  Ferguson  Stock  Option.  
Mr. Ferguson previously achieved the first milestone during the first vesting period. Upon the death of Mr. 
Ferguson, the balance of the shares issuable under the Ferguson Stock Option was forfeited in accordance 
with the terms of the option.

Warrant 
In connection with a $2,500,000 loan that the Company received from Mr. Robert Ferguson (the “Ferguson 
Loan”) on April 1, 2019, the Company issued a warrant to Mr. Ferguson (the “Ferguson Warrant”) for the 
purchase of up to 60,000 shares of our Common Stock at an exercise price of $3.51 per share. The Ferguson 
Loan was paid in full in December 2020. Upon Mr. Ferguson’s death, the Ferguson Warrant was transferred 
equally to Mr. Ferguson’s two heirs with each holding a Warrant for the purchase of up to 30,000 shares of 
the Company’s Common Stock, as permitted under the Ferguson Warrant. On December 12, 2023, one of 
the  Warrants  was  exercised  by  Mr.  Ferguson’s  heir  for  the  purchase  of  30,000  shares  of  the  Company’s 
Common  Stock,  resulting  in  proceeds  received  by  the  Company  of  approximately  $105,000.  As  of 
December 31, 2023, the remaining Warrant remains outstanding and will expire on April 1, 2024.

Common Stock Issued for Services 
The  Company  issued  a  total  of  65,854  and  90,920  shares  of  our  Common  Stock  in  2023  and  2022, 
respectively, under our 2003 Plan to our outside directors as compensation for serving on our Board.  As a 
member of the Board, each director elects to receive either 65% or 100% of the director’s fee in shares of 
our Common Stock.  The number of shares received is calculated based on 75% of the fair market value of 
our Common Stock determined on the business day immediately preceding the date that the quarterly fee is 
due.  The balance of each director’s fee, if any, is payable in cash. The Company recorded approximately 
$477,000 in each of the years 2023 and 2022 in compensation expense (included in SG&A expenses) for the 
for the portion of director fees earned in the Company’s Common Stock.  

Shares Reserved 
As of December 31, 2023, the Company has reserved approximately 994,500 shares of our Common Stock 
for future issuance under all of the option arrangements.

Environmental Liabilities 
The Company has three remediation projects, which are currently in progress relating to our PFD, PFM and 
PFSG subsidiaries, all within our discontinued operations. The Company divested PFD in 2008; however, 
the  environmental  liability  of  PFD  was  retained  by  the  Company  upon  the  divestiture  of  PFD.  These 
remediation projects principally entail the removal/remediation of contaminated soil and, in most cases, the 
remediation of surrounding ground water.  The remediation activities are closely reviewed and monitored by 
the applicable state regulators.  

As  of  December  31,  2023,  the  Company  had  total  accrued  environmental  remediation  liabilities  of 
$845,000, a decrease of $16,000 from the December 31, 2022 balance of $861,000. The decrease represents 
payments for remediation projects. As of December 31, 2023, $61,000 of the total accrued environmental 
liabilities was recorded as current. 

The current and long-term accrued environmental liabilities as of December 31, 2023, are summarized as

Revolving Credit and Term Loan Agreement 
The  Company  entered  into  a  Second  Amended  and  Restated  Revolving  Credit,  Term  Loan  and  Security 
Agreement, dated May 8, 2020 (“Loan Agreement”), with PNC National Association (“PNC” and “lender”), 
acting as agent and lender. The Loan Agreement, as amended from time to time and including the March 21, 
2023,  and  the  July  31,  2023,  amendments  as  discussed  below,  provides  the  Company  with  the  following 
credit  facility  with  a  maturity  date  of  May  15,  2027:  (a)  up  to  $12,500,000  revolving  credit  (“revolving 
credit”), with the maximum that the Company can borrow under the revolving credit based on a percentage 
of  eligible  receivables  (as  defined)  at  any  one  time  reduced  by  outstanding  standby  letters  of  credit  and 
borrowing  reductions  that  the  Company’s  lender  may  impose  from  time  to  time;  (b)  a  term  loan  (“Term 
Loan 1”) of approximately $1,742,000, requiring monthly installments of $35,547; (c) a term loan (“Term 
Loan  2”)  of  $2,500,000,  requiring  monthly  installments  of  $41,667;  and  (d)  a  capital  expenditure  line 
(“Capital Line”) of up to $1,000,000 with advances on the line, subject to certain limitations, permitted for 
up to twelve months starting May 4, 2021 (the “Borrowing Period”), with interest only payable on advances 
during the Borrowing Period. Amounts advanced under the Capital Line at the end of the Borrowing Period 
totaled approximately $524,000, requiring monthly installments of principal of approximately $8,700 plus 
interest, commencing June 1, 2022.  

On March 21, 2023, the Company entered into an amendment to its Loan Agreement, as amended, with its 
lender which provided, among other things, the following: 

 

 

 

 

removed  the  quarterly  FCCR  testing  requirement  for  the  fourth  quarter  of  2022  and  removed  the 
FCCR testing requirement for the first quarter of 2023; 
reduced  the  maximum  revolving  credit  line  under  the  credit  facility  from  $18,000,000  to 
$12,500,000; 
reinstated  the  quarterly  FCCR  testing  requirement  starting  in  the  second  quarter  of  2023  using  a 
trailing  twelve-months  period  (with  no  change  to  the  minimum  1.15:1  ratio  requirement  for  each 
quarter); and  
required  maintenance  of  a  minimum  of  $3,000,000  in  borrowing  availability  under  the  revolving 
credit until the minimum FCCR requirement for the quarter ended June 30, 2023 has been met and 

60 

 
               
             
                  
                
               
                
 
 
 
 
 
 
certified  to  the  lender  (the  Company  met  its  FCCR  in  the  second  quarter  of  2023  which  was 
certified  to  its  lender  and  therefore,  this  requirement  is  no  longer  applicable  under  the  Loan 
Agreement, as amended). 

In connection with the March 21, 2023, amendment, the Company paid its lender a fee of $25,000 which is 
being amortized over the remaining term of the Loan Agreement, as amended, as interest expense-financing 
fees. 

On  July  31,  2023,  the  Company  entered  into  a  further  amendment  to  its  Loan  Agreement,  as  amended, 
which provided, among other things, the following:   

 

 

 

extended  the maturity  date  of  the  Loan  Agreement,  as  amended, to  May  15,  2027,  from May  15, 
2024; 
an additional term loan (“Term Loan 2”) to the Company in the amount of $2,500,000, requiring 
monthly installments of approximately $41,667. The annual rate of interest due on Term Loan 2 is 
at prime (8.50% at December 31, 2023) plus 3.00% or SOFR (as defined in the Loan Agreement, as 
amended)  plus  4.00%  plus  an  SOFR  Adjustment  applicable  for  an  interest  period  selected  by the 
Company.  A  SOFR  Adjustment  rate  of  0.10%  and  0.15%  is  applicable  for  a  one-month  interest 
period and three-month period, respectively, that may be selected by the Company; 
removed the minimum Tangible Adjusted Net Worth (as defined in the Loan Agreement) covenant 
requirement; 

  placed an indefinite reduction in borrowing availability of $750,000; and 
 

allows  for  up  to  $2,500,000  in  capital  expenditure  made  in  fiscal  year  2023  and  thereafter  to  be 
treated  as  financed  capital  expenditure  in  the  Company’s  quarterly  FCCR  covenant  calculation 
requirement.  

At  maturity  of  the  Loan  Agreement,  as  amended,  any  unpaid  principal  balance  plus  interest,  if  any,  will 
become due. 

Pursuant to the amendment dated July 31, 2023, as discussed above, the Company agreed to pay PNC 1.0% 
of  the  total  financing  under  the  Loan  Agreement,  as  amended,  in  the  event  the  Company  pays  off  its 
obligations  on  or  before  July  31,  2024,  and  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. 

In  connection  with  the  amendment  dated  July  31,  2023,  the  Company  paid  its  lender  a  fee  of  $100,000 
which is being amortized over the remaining term of the Loan Agreement, as amended, as interest expense-
financing fees.  

Pursuant to the  Loan  Agreement, as amended,  the  annual rate of interest  due  on  the  revolving  credit is  at 
prime plus 2% or SOFR plus 3.00% plus an SOFR Adjustment applicable for an interest period selected by 
the Company. The annual rate of interest due on Term Loan 1 and the Capital Line is at prime plus 2.50% or 
SOFR  plus  3.50%  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. See payment of annual rate of interest due on 
Term Loan 2 as provided under the amendment dated July 31, 2023. 

The Company’s credit facility under its Loan Agreement, as amended, 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.  The  Company’s  Loan  Agreement,  as  amended,  prohibits  us  from 
paying cash dividends on our Common Stock without prior approval from our lender. The Company was 
not required to perform testing of the FCCR requirement in the first quarter of 2023 pursuant to the March 

61 

 
 
 
 
 
 
 
 
 
21, 2023, amendment as discussed above. It otherwise met all of its other financial covenant requirements. 
The Company met all of its covenant requirements in each of the second to fourth quarters of 2023.  

At December 31, 2023, the borrowing availability under the Company’s credit facility was approximately 
$10,622,000 which included our cash (deposited with the Company’s lender) and was based on our eligible 
receivables  and is  net  of  approximately  $3,950,000 in  outstanding  standby letters  of  credit  and  net  of the 
$750,000 indefinite reduction in borrowing availability imposed by the Company’s lender pursuant to the 
amendment dated July 31, 2023, as discussed above.  

The  following  table  details  the  amount  of the maturities  of  long-term  debt maturing in  future  years as  of 
December 31, 2023 (excludes unamortized debt issuance costs of $170,000).

NOTE 10 
EMPLOYEE RETENTION CREDIT (“ERC”) 

The Coronavirus Aid, Relief and Economic Securities Act (“CARES Act”), which was enacted on March 
27, 2020, provided an Employee Retention Credit (“ERC”) for qualifying businesses keeping employees on 
their  payroll  during  the  COVID-19  pandemic.  The  ERC  was  subsequently  amended  by  the  Taxpayer 
Certainty  and  Disaster  Tax  Relief  Act  of  2020,  the  Consolidated  Appropriation  Act  of  2021,  and  the 
American Rescue Plan Act of 2021, all of which amended and extended the ERC availability and guidelines 
under the CARES Act. Following these amendments, the Company determined that it was eligible for the 
ERC, and as a result of the foregoing legislations, was eligible to claim a refundable tax credit against the 
Company’s share of certain payroll taxes equal to 70% of the qualified wages paid to employees between 
July 1, 2021 and September 30, 2021. Qualified wages were limited to $10,000 per employee per calendar 
quarter in 2021 for a maximum allowable ERC per employee of $7,000 per calendar quarter in 2021. For 
purposes of the amended ERC, an eligible employer was defined as having experienced a significant (20% 
or  more)  decline  in  gross  receipts  during  one  or  more  of  the  first  three  2021  calendar  quarters  when 
compared to 2019.  

During the third quarter of 2022, the Company determined it was eligible for the ERC and amended its third 
quarter  2021  employer  payroll  tax  filings  claiming  a  refund  from  the  U.S.  Treasury  in  the  amount  of 
approximately  $1,975,000.  As  there  is  no  authoritative  guidance  under  U.S.  GAAP  on  accounting  for 
government  assistance  to  for-profit  business  entities,  the  Company  accounted  for  the  ERC  by  analogy  to 
International  Accounting  Standard  ("IAS")  20,  “Accounting  for  Government  Grants  and  Disclosure  of 
Government Assistance.” In accordance with IAS 20, management determined it had reasonable assurance 
for receipt of the ERC and recorded the expected refund as other income (within “Other income (expense)”) 
on the Company’s Consolidated Statements of Operations and other receivables (within “Prepaid and other 
assets”)  on  the  Company’s  Consolidated  Balance  Sheets.  On  March  30,  2023,  the  Company  received  the 
ERC refund of $1,975,000 and approximately $60,000 in interest (recorded within “Interest Income” on the 
Company’s  Consolidated  Statements  of  Operations  for  the  quarter  ended  March  31,  2023),  totaling 
approximately $2,035,000.

In  2022,  the  Company  recorded  a  total  of  approximately  $1,339,000  in  additional  estimated  closure 
liabilities  of  which  approximately  $465,000  (within  long-term)  was  recorded  in  connection  with  the 
footprint expansion at one of our facilities and an update to a processing enclosure area at another facility. 
The  remaining  additional  closure  liabilities  was  recorded  for  our  EWOC  facility  for  decommissioning 
activities due to changes in estimated closure costs.  

As  of  December  31,  2023,  and  December  31,  2022,  the  current  portion  of  the  closure  liabilities  totaled 
approximately $79,000 and $682,000, respectively, which reflect closure liabilities for our EWOC facility. 
The spending made in each of the years 2023 and 2022 was primarily for our EWOC facility. 

The  reported  closure  asset  or  ARO,  is  reported  as  a  component  of  “Net  Property  and  equipment”  in  the

The global intangible low-taxed income (“GILTI”) provisions under the Tax Cuts and Jobs Act of 2017 (the 
“TCJA”) require the Company to include in its U.S. income tax return foreign subsidiary earnings in excess 
of an allowable return on the foreign subsidiary’s tangible assets. The Company has elected to account for 
GILTI tax in the period in which it is incurred, and therefore has not provided any deferred tax impacts of 
GILTI  in  its consolidated financial  statements for  the  years  ended  December  31,  2023  and  2022.    As the 
Canada  and  United  Kingdom  foreign  subsidiaries  are  in  loss  positions  for  2023,  no  GILTI  inclusion  is 
expected for these entities for the current year.  

The  Company  had  temporary  differences  and  net  operating loss  carry  forwards  from  both  our  continuing 
and discontinued operations, which gave rise to deferred tax assets as of December 31, 2023, and 2022 as 
follows (in thousands): 

Deferred tax assets:

Net operating losses

As of December 31, 2023, the Company assessed whether its deferred tax asset will more likely than not to 
be  realized.  This  assessment  included  both  positive  and  negative  available  evidences,  which  included  the 
Company’s  current  contracts,  cumulative  loss,  future  reversal  of  existing  taxable  differences,  and  overall 
prospect of future business and earnings. Based on the weight of these available evidences, the Company 
concluded that it will more likely than not utilize its Federal and certain state net operating losses.

purposes  of  approximately  $19,450,000  and  $72,859,000,  respectively,  as  of  December  31,  2023.  These 
NOLs  can  be  carried  forward  and  applied  against  future  taxable  income,  if  any,  and  expire  in  various 
amounts starting in 2023. All of our federal NOLs were generated after December 31, 2017 and thus do not 
expire.  

The  Company  accounts  for  uncertainties  in  income  tax  pursuant  to  ASC  740.  A  reconciliation  of  the 
beginning and ending amount of our recognized tax expense is summarized as follows (in thousands):

The tax years 2020 through 2022 remain open to examination by taxing authorities in the jurisdictions in 
which the Company operates. 

The Company had $76,000 and $0 federal income tax payable for the years ended December 31, 2023 and 
2022, respectively. 

Beginning  in  2022,  the  Tax  Cuts  and  Jobs  Act  of  2017  (the  “TCJA”)  amended  Section  174  to  eliminate 
current-year deductibility of research and experimentation (“R&E”) expenditures and software development 
costs (collectively, “R&E expenditures”) and instead require taxpayers to charge their R&E expenditures to 
a  capital  account  amortized  over  five  years  (15  years  for  expenditures  attributable  to  R&E  activity 
performed  outside  the  United  States).  For  each  tax  year  2023  and  2022,  the  Company  has  capitalized 
$2,059,000 of research and development expenses. While Management believes the estimate for 2023 to be 
materially accurate, the Company plans to complete a formal IRC Section 174 analysis in advance of filing 
the tax return for the year ended December 31, 2023. 

NOTE 14 
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. 

66 

 
 
 
         
         
 
 
 
 
 
 
 
 
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. 

The  Company’s  insurance  carrier  is  providing  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  have  been  dismissed  by  the  Court.  Remaining  claims  include:  (1) 
intentional  interference  with  contractual  relations;  and  (2)  inducing  a  breach  of  contract.  The  Company 
continues to believe it has no liability exposure to Tetra Tech. 

Insurance 
The Company has a 25-year finite risk insurance policy entered into in June 2003 (“2003 Closure Policy”) 
with 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 $22,461,000 at 
December  31,  2023.  As  of  December  31,  2023,  and  December  31,  2022,  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  Consolidated  Balance  Sheets  totaled  $12,074,000  and  $11,570,000,  respectively, 
which  included  interest  earned  of  $2,603,000  and  $2,099,000  on  the  finite  risk  sinking  funds  as  of 
December 31, 2023 and December 31, 2022, respectively. Interest income for the year ended 2023 and 2022 
was approximately $504,000 and $99,000, 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. 

Perma-Fix Canada Inc. (“PF Canada”) 
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. As of December 31, 2023, PF Canada has approximately $2,389,000 in unpaid receivables due 
from CNL as a result of work performed under the TOA. CNL and PF Canada have reached a settlement 
agreement  on  payment  of  the  aforementioned    receivables  to  PF  Canada  by  CNL,  subject  to  certain 
conditions/terms precedents being met, including release of certain liens. (see “Note 19 - Subsequent Event 
– PF Canada” for a discussion of a partial payment made by CNL in January 2024 on the receivables and 
the remaining receivables to be paid by CNL). 

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.  At  December  31, 
2023, the total amount of standby letters of credit outstanding was approximately $3,950,000 and the total 
amount of bonds outstanding was approximately $36,674,000.   

NOTE 15 
PROFIT SHARING PLAN 

The Company adopted a 401(k) Plan in 1992, which is intended to comply with Section 401 of the Internal 
Revenue Code and the provisions of the Employee Retirement Income Security Act of 1974. All full-time 
employees  who  have  attained  the  age  of  18  are  eligible  to  participate  in  the  401(k)  Plan.  Eligibility  is

NOTE 17 
SEGMENT REPORTING 

In accordance with ASC 280, “Segment Reporting”, we define an operating segment as a business activity: 

  from which we may earn revenue and incur expenses; 
  whose operating results are regularly reviewed by the CODM to make decisions about 

resources to be allocated to the segment and assess its performance; and 

  for which discrete financial information is available. 

We have two reporting segments, consisting of the Treatment and Services Segments, which are based on a 
service offering approach. Our reporting segments exclude our corporate headquarter, business center and 
our discontinued operations (see “Note 8 – Discontinued Operations”) which do not generate revenues. 

The table below shows certain financial information of our reporting segments as of and for the years ended 
December 31, 2023, and 2022 (in thousands).

NOTE 18 
EMPLOYEMENT AGREEMENTS AND MIPS 

Employment Agreements 
On April 20, 2023, the Company entered into employment agreements with each of its executive officers: 
Mark  Duff,  President  and  CEO;  Ben  Naccarato,  EVP  and  CFO;  Dr.  Louis  Centofanti,  EVP  of  Strategic 
Initiatives;  Andrew  Lombardo,  EVP  of  Nuclear  and  Technical  Services;  and  Richard  Grondin,  EVP  of 
Waste Treatment Operations (collectively the “New Employment Agreements” and each, individually, the 
“New Employment Agreement”). The Company had previously entered into employment agreements with 
each of the aforementioned executive officers on July 22, 2020, all five of which agreements were due to 
expire on July 22, 2023, but which were terminated effective April 20, 2023, upon the execution of the New 
Employment Agreements.  

Each of the New Employment Agreements are substantially identical except for compensation. Under the 
New Employment Agreements, each of these executive officers is provided an annual salary, which annual 
salary may be increased from time to time, but not reduced, as determined by the Compensation Committee. 
In addition, each of these executive officers is entitled to participate in the Company’s broad-based benefits 
plans and to certain performance compensation payable under separate Management Incentive Plan (“MIP”) 
as approved by the Company’s Compensation Committee and the Company’s Board.   

Each  of  the  New  Employment  Agreements  is  effective  for  three  years  from  April  20,  2023  (the  “Initial 
Term”) unless earlier terminated by the Company or by the executive officer. At the end of the Initial Term 
of each New Employment Agreement, each New Employment Agreement will automatically be extended 
for one additional year, unless at least six months prior to the expiration of the Initial Term, the Company or 
the executive officer provides written notice not to extend the terms of the New Employment Agreement. 
Mr.  Andrew  Lombardo  retired  from  the  position  of  EVP  of  Nuclear  and  Technical  Services  effective 
January  1,  2024.  Upon  Mr.  Lombardo’s  retirement  from  the  position  of  EVP  of  Nuclear  and  Technical 
Services, he no longer was an executive officer of the Company and his employment agreement dated April 
20, 2023, was terminated effective January 1, 2024. Mr. Lombardo remains employed by the Company at a 
reduced  capacity,  and  assists  with  the  transition  of  his  former  responsibilities  as  well  as  contributing  to 
certain business development matters. 

Pursuant to the New Employment Agreements, if the executive officer’s employment is terminated due to 
death, disability or for cause (as defined in the agreements), the Company will pay to the executive officer 
or  to  his  estate  an  amount  equal  to the  sum  of  any  unpaid  base  salary  and  accrued  unused  vacation  time 
through the date of termination and any benefits due to the executive officer under any employee benefit 
plan  (the  “Accrued  Amounts”)  plus  any  performance  compensation  payable  pursuant  to  the  MIP  with 
respect  to  the  fiscal  year  immediately  preceding  the  date  of  termination.  In  the  event  that  an  executive 
officer’s  employment  is  terminated  due  to  death,  the  Company  will  also  pay  a  lump-sum  payment  (the 
“Cash Medical Continuation Benefit”) equal to eighteen times the monthly premium that would be required 
to  be  paid,  pursuant  to  the  Consolidated  Omnibus  Budget  Reconciliation  Act  of  1985,  as  amended 
(“COBRA”), to continue group health coverage for the executive officer’s eligible covered dependents in 
effect on the date of the executive officer’s termination of employment, based on the premium for the first 
month of COBRA coverage. Such cash payment will be taxable and will be made regardless of whether the 
executive officer’s eligible covered dependents elect COBRA continuation coverage.  

If the executive officer terminates his employment for “good reason” (as defined in the agreements) or is 
terminated  by  the  Company  without  cause  (including  any  such  termination  for  “good  reason”  or  without 
cause within 24 months after a Change in Control (as defined in the agreements), the Company will pay the 
executive officer Accrued Amounts, (a) two years of full base salary, plus (b) (i) two times the performance 
compensation  (under  the  executive  officer’s  MIP)  earned  with  respect  to  the  fiscal  year  immediately 
preceding the date of termination provided the performance compensation earned with respect to the fiscal 
year  immediately  preceding  the  date  of  termination  has  not  yet  been  paid,  or  (ii)  if  performance 
compensation  earned  with  respect  to  the  fiscal  year  immediately  preceding  the  date  of  termination  has 
70 

 
 
 
 
 
 
 
already  been  paid  to  the  executive  officer,  the  executive  officer  will  be  paid  an  additional  year  of  the 
performance  compensation  earned  with  respect  to  the  fiscal  year  immediately  preceding  the  date  of 
termination,  and  (c)  the  Cash  Medical  Continuation  Benefit.  If  the  executive  officer  terminates  his 
employment  for  a  reason  other  than  for  good  reason,  the  Company  will  pay  to  the  executive  officer  an 
amount  equal  to  the  Accrued  Amounts  plus  any  performance  compensation  payable  pursuant  to  the  MIP 
applicable to such executive officer.    

Additionally,  in  the  event  of  a  Change  in  Control  (as  defined  in  the  agreements),  all  outstanding  stock 
options to purchase common stock held by the executive officer will immediately become exercisable in full 
commencing on the date of termination through the original term of the options. In the event of the death of 
an executive officer, all outstanding stock options to purchase common stock held by the executive officer 
will immediately become exercisable in full commencing on the date of death, with such options exercisable 
for the lesser of the original option term or twelve months from the date of the executive officer’s death. In 
the event an executive officer terminates his employment for “good reason” (as defined in the agreements) 
or  is  terminated  by the  Company  without  cause,  all outstanding stock  options  to  purchase  common  stock 
held by the officer will immediately become exercisable in full commencing on the date of termination, with 
such  options  exercisable  for  the  lesser  of the  original  option term  or  within  60  days  from  the  date  of the 
executive officer’s date of termination. Severance benefits payable with respect to a termination (other than 
Accrued  Amounts)  shall  not  be  payable  until  the  termination  constitutes  a  “separation  from  service”  (as 
defined under Treasury Regulation Section 1.409A-1(h)).  

MIPs 
On January 19, 2023, the Board and the Compensation Committee approved individual MIP for the calendar 
year  2023  for  each  of  the  Company’s  executive  officers.  Each  MIP  was  effective  January  1,  2023,  and 
applicable for year 2023. Each MIP provided 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  was  based  upon  meeting  certain  of  the  Company’s  separate  target 
objectives during 2023. The total potential target performance compensation payable ranged from 25% to 
150% of the 2023 base salary for the CEO ($93,717 to $562,304), 25% to 100% of the 2023 base salary for 
the CFO ($76,193 to $304,772), 25% to 100% of the 2023 base salary for the EVP of Strategic Initiatives 
($63,495 to $253,980), 25% to 100% of the 2023 base salary for the EVP of Nuclear and Technical Services 
($76,193  to  $304,772),  and  25%  to  100%  ($65,308  to  $261,233)  of  the  2023  base  salary  for  the  EVP  of 
Waste  Treatment  Operations.  Total  compensation  earned  under  the  five  2023  MIPs  were  approximately 
$750,000, which is to be paid on or about 90 after year-end, or sooner, based on the Company’s filing of its 
2023  Form  10-K.  As  disclosed  above,  Mr.  Lombardo  retired  from  the  position  of  EVP  of  Nuclear  and 
Technical Services effective January 1, 2024. He is entitled to compensation earned under his 2023 MIP as 
EVP of Nuclear and Technical Services. 

NOTE 19 
SUBSEQUENT EVENTS 

The  Company  evaluated  subsequent  events  and  transactions  that  occurred  after  the  balance  sheet  date 
through March 13, 2024, the date that these consolidated financial statements were available to be issued. 
Based  upon  this  review,  the  Company  did  not  identify  any  subsequent  events  that  would  have  required 
adjustment or disclosure in the consolidated financial statements other than the below.  

MIPs 
On  January  18,  2024,  the  Board  (with  Mr.  Mark  Duff  and  Dr.  Louis  Centofanti  abstaining)  and  the 
Compensation  Committee  approved  individual  MIP  for  the  calendar  year  2024  for  each  of  our  executive 
officers. Each MIP is effective January 1, 2024 and applicable for year 2024. 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  2024.  The  total  potential  target  performance 
compensation  payable  ranges  from  25%  to  150%  of  the  2024  base  salary  for  the  CEO  ($104,287  to 
$625,733), 29% to 100% of the 2024 base salary for the CFO ($95,681 to $332,811), 25% to 100% of the 
71 

 
 
 
 
 
 
2024 base salary for the EVP of Strategic Initiatives ($69,337 to $277,346), and 25% to 100% ($71,317 to 
$285,267) of the 2024 base salary for the EVP of Waste Treatment Operations. 

PF Canada 
As discussed in “Note 14 – Commitment and Contingencies - Perma-Fix Canada Inc. (“PF Canada”),” the 
Company’s  subsidiary,  PF  Canada.  has  unpaid  receivables  due  from  CNL  for  a  previous  TOA  that  PF 
Canada  entered  into  with  CNL  in  May  2019  for  remediation  work  within  Ontario,  Canada  in  which  a 
settlement  agreement  on  the  payment  of  the  receivables  by  CNL  was  reached,  subject  to  certain 
conditions/terms  precedents  being  met,  including  release  of  certain  liens.  On  January  22,  2024,  the 
Company  received  approximately  $741,000  of  the  $2,389,000  in  unpaid  receivables,  with  the  remaining 
receivables  to  be  paid  by CNL  upon  completion  of  the  settlement  conditions/terms,  which the  Company 
believes should occur during 2024.

AND FINANCIAL DISCLOSURE 
None. 

ITEM 9A.  CONTROLS AND PROCEDURES 

Evaluation of disclosure controls and procedures. 
We maintain disclosure controls and procedures that are designed to ensure that information 
required  to  be  disclosed  in  our  periodic  reports  filed  with  the  Securities  and  Exchange 
Commission (the “Commission”) is recorded, processed, summarized and reported within the 
time periods specified in the rules and forms of the Commission and that such information is 
accumulated  and  communicated  to  our  management,  including  the  Chief  Executive  Officer 
(“CEO”)  (Principal  Executive  Officer),  and  Chief  Financial  Officer  (“CFO”)  (Principal 
Financial Officer), as appropriate to allow timely decisions regarding the required disclosure. 
In  designing  and  assessing  our  disclosure  controls  and  procedures,  our  management 
recognizes that any controls and procedures, no matter how well designed and operated, can 
provide only reasonable assurance of achieving their stated control objectives and are subject 
to  certain  limitations,  including  the  exercise  of  judgment  by  individuals,  the  difficulty  in 
identifying  unlikely  future  events,  and  the  difficulty  in  eliminating  misconduct  completely.  
Our management, with the participation of our CEO and CFO, evaluated the effectiveness of 
our  disclosure  controls  and  procedures  pursuant  to  Rule  13a-15(e)  and  15d-15(e)  of  the 
Securities  Exchange  Act  of  1934,  as  amended.  Based  upon  this  assessment,  our  CEO  and 
CFO  have  concluded  that  our  disclosure  controls  and  procedures  were  effective  as  of 
December 31, 2023.  

Management's Report on Internal Control over Financial Reporting 
Our  management  is  responsible  for  establishing  and  maintaining  adequate  internal  control 
over  financial  reporting,  as  such  term  is  defined  in  Rules  13a-15(f)  and  15d-15(f)  of  the 
Securities  Exchange  Act  of  1934.  Internal  control  over  financial  reporting  is  designed  to 
provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the 
preparation  of  financial  statements  for  external  purposes  in  accordance  with  accounting 
principles  generally  accepted  in  the  United  States  of  America.  Because  of  its  inherent 
limitations, internal control over financial reporting may not prevent or detect misstatements 
or  fraudulent  acts.  Also,  projections  of  any  evaluation  of  effectiveness  to  future  periods  are 
subject to the risk that controls may become inadequate because of changes in conditions, or 
that  the  degree  of  compliance  with  the  policies  or  procedures  may  deteriorate.  A  control 
system, no matter how well designed, can provide only reasonable assurance with respect to 
financial statement preparation and presentation.   

Internal control over financial reporting includes those policies and procedures that (i) pertain 
to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the 
transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance 
that  transactions  are  recorded  as  necessary  to  permit  the  preparation  of  the  consolidated 
financial statements in accordance with generally accepted accounting principles in the United 

72 

 
 
 
 
 
 
 
 
 
 
 
 
States of America, and that receipts and expenditures of the Company are being made only in 
accordance with appropriate authorizations of management and directors of the Company; and 
(iii) provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized 
acquisition, use or disposition of the Company's assets that could have a material effect on the 
consolidated financial statements. 

Management,  with  the  participation  of  our  CEO  and  CFO,  conducted  an  assessment  of  the 
effectiveness of internal control over financial reporting as of December 31, 2023 based on the 
framework  in  Internal  Control  –  Integrated  Framework  (2013)  issued  by  the  Committee  of 
Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, 
management  and  our  CEO  and  CFO,  concluded  that  the  Company’s  internal  control  over 
financial reporting was effective as of December 31, 2023. 

This  Form  10-K  does  not  include  an  attestation  report  of  the  Company’s  independent 
registered public accounting firm regarding internal control over financial reporting.  Since the

which  is  critical  for  a  waste  management  company.  In  addition,  his  service  in  the  government  sector 
provides a solid foundation for the continuing growth of the Company, particularly within the Company’s 
Nuclear  business.  Dr.  Centofanti’s  comprehensive  understanding  of  the  Company’s  operations  and  his 
extensive  knowledge  of  its  history,  coupled  with  his  drive  for  innovation  and  excellence,  positions  Dr.

Segments.  In  the  Treatment  Segment,  he  continues  to  upgrade  each  facility  to  increase  efficiency  and 
modernize  treatment  capabilities  to  meet  the  changing  markets  associated  with  the  waste  management 
industry.  This  growth  includes  expansion  into  additional  market  sectors  including  development  of  new

As a director since our inception, Mr. Zwecker’s understanding of our business provides valuable insight to 
the Board.  With years of experience in operations and finance for various companies, including a number 
of  waste  management  companies,  Mr.  Zwecker  combines  extensive  knowledge  of  accounting  principles, 
financial  reporting  rules  and  regulations,  the  ability  to  evaluate  financial  results,  and  understanding  of 
financial  reporting  processes.  He  has  an  extensive  background  in  operating  complex  organizations.  Mr. 
Zwecker’s experience and background position him well to serve as a member of our Board. These factors 
led the Board to conclude that he should serve as a director. 

Board Skills Matrix 
The  Company  is  focused  on  nominating  a  Board  of  Directors  with  a  balance  of  functional  expertise, 
leadership  experience,  high  moral  character,  critical  thinking,  and  a  diversity  of  backgrounds  and  tenure

CORPORATE GOVERNANCE AND NOMINATING COMMITTEE 
We  have  a  separately-designated  standing  Corporate  Governance  and  Nominating  Committee  (the 
“Governance  and  Nominating  Committee”).  Members  of  the  Governance  and  Nominating  Committee 
during 2023 were Joe R. Reeder (Chairperson), Thomas P. Bostick, Kerry C. Duggan and Zach P. Wamp. 
All members of the Nominating Committee are and were “independent” as that term is defined by current 
Nasdaq listing standards. 

The Governance and Nominating Committee has specific responsibilities which include: 

 

considering  and  making  recommendations  to  the  Board  regarding  the  composition  and 
chairmanship of the committees of our Board; 

  developing and making recommendations to our Board regarding corporate governance guidelines 
which include policies and procedures that promote honest and ethical conduct and prohibit conflict 
of interest in business conduct;  

  overseeing evaluations of the Board’s performance, including committees of the Board; and 
  overseeing Company practices and initiatives with respect to environmental, social and governance 

matters.  

The  Governance  and  Nominating  Committee  recommends  to  the  Board  of  Directors  candidates  to  fill 
vacancies on the Board and the nominees for election as directors at each annual meeting of stockholders. In 
making such recommendations, the Governance and Nominating Committee takes into account information 
provided to them from the candidates, as well as the Committee’s own knowledge and information obtained 
through inquiries to third parties to the extent the Committee deems appropriate. The Company’s Bylaws 
sets  forth  certain  minimum  director  qualifications  to  qualify  as  a  nominee  for  election  as  a  director.  To 
qualify for nomination or for election as a director, an individual must: 

  be an individual at least 21 years of age who is not under legal disability; 
  have  the  ability  to  be  present,  in  person,  at  all  regular  and  special  meetings  of  the  Board  of 

Directors; 

  not serve on the boards of more than three other publicly-held companies;  
 

satisfy the director qualification requirements of all environmental and nuclear commissions, boards 
or similar regulatory or law enforcement authorities to which the Company is subject so as not to

cause  the  Company  to  fail  to  satisfy  any  of  the  licensing  requirements  imposed  by  any  such 
authority;  

  not be affiliated with, employed by or be a representative of, or have or acquire a material personal 
involvement  with,  or  material  financial  interest  in,  any  “Business  Competitor”  (as  defined  in  the 
Bylaws); 

  not have been convicted of a felony or of any misdemeanor involving moral turpitude; and 
  have  been  nominated  for  election  to  the  Board  of  Directors  in  accordance  with  the  terms  of  the 

Bylaws. 

In addition to the minimum director qualifications as mentioned above, in order for any proposed nominee 
to  be  eligible to  be  a candidate for election  to  the  Board of  Directors,  such  candidate must deliver to the 
Governance  and  Nominating  Committee  a  completed  questionnaire  with  respect  to  the  background, 
qualifications,  stock  ownership  and  independence  of  such  proposed  nominee.  The  Governance  and 
Nominating Committee reviews each candidate’s qualifications to include considerations of: 

 

 
 

standards  of  integrity,  personal  ethics  and  values,  commitment,  and  independence  of  thought  and 
judgment; 
ability to represent the interests of the Company’s stockholders;  
ability  to  dedicate  sufficient  time, energy  and  attention  to fulfill  the requirements  of the  position; 
and 

  diversity  of  skills  and  experience  with  respect  to  accounting  and  finance,  management  and 
leadership,  business  acumen,  vision  and  strategy,  charitable  causes,  business  operations,  and 
industry knowledge.   

The Governance and Nominating Committee does not assign specific weight to any particular criteria and 
no  particular  criterion  is  necessarily  applicable  to  all  prospective  nominees.  The  Governance  and 
Nominating  Committee  does  not  have  a  formal  policy  for  the  consideration  of  diversity  in  identifying 
nominees for directors. However, diversity is one of the many factors taken into account when considering 
potential  candidates  to  serve  on  the  Board  of  Directors.  The  Company  recognizes  that  diversity  in 
professional and life experiences may include consideration of gender, race, cultural background or national 
origin,  in  identifying  individuals  who  possess  the  qualifications  that  the  Governance  and  Nominating 
Committee  believes  are  important  to  be  represented  on  the  Board.  The  Company  also  views  and  values 
diversity  from  the  perspective  of  professional  and  life  experiences,  as  well  as  geographic  location, 
representative of the markets in which we do business. The Company believes that the inclusion of diversity 
as one of many factors considered in selecting director nominees is consistent with the Company's goal of 
creating a board of directors that best serves our needs and those of our shareholders.  

Stockholder Nominees 
The Governance and Nominating Committee will consider properly submitted stockholder nominations for 
candidates for membership on the Board from stockholders who meet each of the requirements set forth in 
the Bylaws, including, but not limited to, the requirements that any such stockholder own at least 1% of the 
Company’s  shares  of  the  Common  Stock  entitled  to  vote  at  the  meeting  on  such  election,  has  held  such 
shares continuously for at least one full year, and continuously holds such shares through and including the 
time of the annual or special meeting. Nominations of persons for election to the Board may be made at any 
Annual  Meeting  of  Stockholders,  or  at  any  Special  Meeting  of  Stockholders  called  for  the  purpose  of 
electing directors. Any stockholder nomination (“Proposed Nominee”) must comply with the requirements 
of the Company’s Bylaws and the Proposed Nominee must meet the minimum qualification requirements as 
discussed  above.  For  a  nomination  to  be  made  by  a  stockholder,  such  stockholder  must  provide  advance 
written  notice  to  the  Governance  and  Nominating  Committee,  delivered  to  the  Company’s  principal 
executive office address (i) in the case of an Annual Meeting of Stockholders, no later than the 90th day nor 
earlier  than  the  120th  day  prior  to  the  anniversary  date  of  the  immediately  preceding  Annual  Meeting  of 
Stockholders; and (ii)  in the  case  of  a  Special Meeting  of  Stockholders  called for the  purpose  of  electing 
directors, not later than the 10th day following the day on which public disclosure of the date of the Special 
Meeting of Stockholders is made.   

81 

 
 
 
 
 
 
The Governance and Nominating Committee will evaluate the qualification of the Proposed Nominee and 
the  Proposed  Nominee’s  disclosure  and  compliance  requirements  in  accordance  with  the  Company’s 
Bylaws. If the Board, upon the recommendation of the Governance and Nominating Committee, determines 
that a nomination was not made in accordance with the Company’s Bylaws, the Chairman of the Meeting 
shall declare the nomination defective and it will be disregarded. 

BOARD LEADERSHIP STRUCTURE 
We currently separate the roles of Chairman of the Board and CEO. The Board believes that this leadership 
structure promotes balance between the Board’s independent authority to oversee our business, and the CEO 
and his management team, who manage the business on a day-to-day basis.  

The Company does not have a written policy with respect to the separation of the positions of Chairman of 
the  Board  and  CEO.  The  Company  believes  it  is  important  to  retain  its  flexibility  to  allocate  the 
responsibilities  of  the  offices  of  the  Chairman  and  CEO  in  any  way  that  is  in  the  best  interests  of  the 
Company at a given point in time; therefore, the Company’s leadership structure may change in the future 
as circumstances may dictate. 

Mark A. Zwecker, a current member of our Board, continues to serve as the Independent Lead Director, a 
position he has held since February 2010. The Lead Director’s role includes:  

 

 
 
 

convening and chairing meetings of the non-employee directors as necessary from time to time and 
Board meetings in the absence of the Chairman of the Board; 
acting as liaison between directors, committee chairs and management;  
serving as an information source for directors and management; and 
carrying out responsibilities as the Board may delegate from time to time. 

AUDIT COMMITTEE 
We  have  a  separately  designated  standing  Audit  Committee  of  our  Board  established  in  accordance  with 
Section  3(a)(58)(A)  of  the  Exchange  Act.  Members  of  the  Audit  Committee  are  Mark  A.  Zwecker 
(Chairperson), Joseph T. Grumski and Larry M. Shelton.  

Our Board has determined that each of our Audit Committee members is independent within the meaning of 
the  rules  of  the  Nasdaq  and  is  an  “audit  committee  financial  expert”  as  defined  by  Item  407(d)(5)(ii)  of 
Regulation S-K of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).   

The Audit Committee has also discussed with Grant Thornton, LLP, the Company’s independent registered 
accounting  firm,  the  matters  required  to  be  discussed  by  Public  Company  Accounting  Oversight  Board 
(“PCAOB”) Auditing Standard No. 16 (Communications with Audit Committee). 

BOARD OF DIRECTOR INDEPENDENCE 
The  Board  has  determined  that  each  director,  other than  Dr.  Centofanti  and  Mark  Duff,  is  “independent” 
within the meaning of applicable Nasdaq rules. Each of Dr. Centofanti and Mark Duff is not deemed to be 
an “independent director” because of his employment as an executive officer of the Company.  

COMPENSATION AND STOCK OPTION COMMITTEE  
The Compensation and Stock Option Committee (the “Compensation Committee”) reviews and recommends 
to  the  Board  the  compensation  and  benefits  of  all  of  the  Company’s  officers  and  reviews  general  policy 
matters relating to compensation and benefits of the Company’s employees. The Compensation Committee 
also administers the Company’s stock option plans. The Compensation Committee has the sole authority to 
retain and terminate a compensation consultant, as well as to approve the consultant’s fees and other terms of 
engagement.  It  also  has  the  authority  to  obtain  advice  and  assistance  from  internal  or  external  legal, 
accounting  or  other  advisors.  No  compensation  consultant  was  employed  during  2023.  Members  of  the 
Compensation Committee during 2023 were Joseph T. Grumski (Chairperson), Zach P. Wamp and Mark A. 
Zwecker. None of the members of the Compensation Committee has been or is an officer or employee of the 
Company  or  has  had  or  has  any  relationship  with  the  Company  requiring  disclosure  under  applicable 

82 

 
 
 
 
 
 
 
 
 
 
Commission regulations. 

STRATEGIC ADVISORY COMMITTEE      
We have a separately designated Strategic Advisory Committee (the “Strategic Committee”). The primary 
functions  of  the  Strategic  Committee  are  to  investigate  and  evaluate  strategic  alternatives  available  to  the 
Company and to work with management on long-range strategic planning and identification of potential new 
business  opportunities.  The  members  of  the  Strategic  Advisory  Committee  are  Dr.  Louis  Centofanti 
(Chairperson),  Kerry  C.  Duggan,  Joe  R.  Reeder,  and  Zach  P.  Wamp,  who  replaced  Mark  A.  Zwecker, 
effective October 19, 2023.   

The Board has adopted a written charter for each of the Audit Committee, the Compensation Committee, the 
Governance and Nominating Committee, and the Strategic Advisory Committee, each of which is available 
on our website at https://ir.perma-fix.com/governance-docs.

Certificate  of  Business  Management  from  the  School  of  Higher  Commercial  Studies  from  Montreal 
University (Montreal, Canada). 

Certain Relationships 
There are no family relationships between any of the directors or executive officers. 

Section 16(a) Beneficial Ownership Reporting Compliance 
Section  16(a)  of  the  Exchange  Act,  and  the  regulations  promulgated  thereunder  require  our  executive 
officers  and  directors  and  beneficial  owners  of  more  than  10%  of  our  Common  Stock  to  file  reports  of 
ownership and changes of ownership of our Common Stock with the Commission, and to furnish us with 
copies of all such reports. Based solely on a review of the copies of such reports furnished to us and written 
information  provided  to  us,  we  believe  that  during  2023  none  of  our  executive  officers,  directors,  or 
beneficial owners of more than 10% of our Common Stock failed to timely file reports under Section 16(a).   

Schelhammer Capital Bank AG, a banking institution regulated by the banking regulations of Austria, has 
represented to the Company that as of February 1, 2024, it holds of record as a nominee for, and as an agent 
of, certain accredited investors, 1,837,572 shares of our Common Stock.  Schelhammer Capital Bank AG 
has  also  represented  to  the  Company  that  none  of  the  investors,  individually  or  as  a  group,  as  the  term 
“group”  is  defined  under  Rule  13d-5(b)  of  the  Exchange  Act,  beneficially  owns  more  than  4.9%  of  our 
Common Stock. Additionally, the investors for whom Schelhammer Capital Bank AG acts as nominee with 
respect  to  such  shares  maintain  full  voting  and  dispositive  power  over  the  Common  Stock  beneficially 
owned by such investors, and Schelhammer Capital Bank AG has neither voting nor investment power over 
such shares. Accordingly, Schelhammer Capital Bank AG believes that (i) it is not the beneficial owner, as 
such  term  is  defined  in  Rule  13d-3  of  the  Exchange  Act,  of  the  shares  of  Common  Stock  registered  in 
Schelhammer  Capital  Bank  AG’s  name  because  (a)  Schelhammer  Capital  Bank  AG  holds  the  Common 
Stock as a nominee only, (b) Schelhammer Capital Bank AG has neither voting nor investment power over 
such shares, and (c) Schelhammer Capital Bank AG has not nominated or sought to nominate, and does not 
intend to nominate in the future, any person to serve as a member of our Board; and (ii) it is not required to 
file  reports  under  Section  16(a)  of  the  Exchange  Act  or  to  file  either  Schedule  13D  or  Schedule  13G  in 
connection with the shares of our Common Stock registered in the name of Schelhammer Capital Bank AG. 

If  the  representations  of,  or  information  provided  by  Schelhammer  Capital  Bank  AG,  are  incorrect  or 
Schelhammer Capital Bank AG was historically acting on behalf of its investors as a group, rather than on 
behalf  of  each  investor  independent  of  other  investors,  then  Schelhammer  Capital  Bank  AG  and/or  the 
investor group would have become a beneficial owner of more than 10% of our Common Stock on February 
9,  1996,  as  a  result  of  the  acquisition  on  such  date  of  1,100  shares  of  our  Preferred  Stock  that  were 
convertible into a maximum of 256,560 shares of our Common Stock.  If either Schelhammer Capital Bank 
AG or a group of Schelhammer Capital Bank AG’s investors became a beneficial owner of more than 10% 
of our Common Stock on February 9, 1996, or at any time thereafter, and thereby required to file reports 
under Section 16(a) of the Exchange Act, then Schelhammer Capital Bank AG has failed to file a Form 3 or 
any Forms 4 or 5 since February 9, 1996. (See “Item 12 - Security Ownership of Certain Beneficial Owners 
and Management and Related Stockholder Matters – Security Ownership of Certain Beneficial Owners” for 
a discussion of Schelhammer Capital Bank AG’s current record ownership of our securities).

Code of Ethics 
Our  Code  of  Business  Conduct  and  Ethics  (“Code  of  Ethics”),  which  applies  to  our  Board  and  all  our 
employees,  including  our CEO  and  our  senior  financial  officers,  complies  with  applicable  SEC  rules  and 
Nasdaq listing standards. and is available on our website at https://ir.perma-fix.com/governance-docs.  The 
provisions of the Code of Ethics that apply to the CEO and our senior financial officers, including our CFO 
and  our  chief  accounting  officer,  complies  with  the  requirements  imposed  by  the  Sarbanes-Oxley  Act  of 
2002 and the rules issued thereunder for codes of ethics applicable to such officers.  If any amendments are 
made to the Code of Ethics, or any grants of waivers are made to any provision of the Code of Ethics, that 
are  applicable to  our  CEO  and  our  senior financial  officers,  we  will  promptly disclose the  amendment or 
waiver and nature of such amendment or waiver on our website at the same web address.

(1) On May 22, 2023, Mr. Duff exercised 100% of his ISO granted to him on July 27, 2017 under the Company’s 2017 Stock Option 
Plan for the purchase of up to 100,000 shares (Option Shares) of the Company’s Common Stock at $3.65 per share. As permitted 
by the 2017 Stock Option Plan, Mr. Duff elected to pay the exercise price of the Option Shares by having the Company withhold 
from the Option Shares a number of shares having a fair market value equal to the aggregate exercise price of $365,000. Since the 
fair market value of the Company’s Common Stock on May 22, 2023, (as determined in accordance with the 2017 Stock Option 
Plan)  was  $11.05  per  share, the Company  withheld 33,032  shares  of  Common  Stock  ($365,000 divided  by $11.05)  to pay  the 
aggregate  exercise  price  for  the  Option  Shares  and  issued  66,968  shares  to  Mr.  Duff.  Realized  value  on  this  exercise  was 
determined  based  on  the  difference  between  the  (a)  exercise  price  ($3.65)  per  share  of  the  Option  Shares  multiplied    by  the 
100,000  Option  Shares  exercised,  and  (b)  the  market  value  ($11.05)  on  the  date  of  exercise  of  the  Option  Shares  times  the 
100,000 Option Shares exercised.   

(2) On May 22, 2023, Mr. Naccarato exercised 100% of his ISO granted to him on July 27, 2017 under the Company’s 2017 Stock 
Plan for the purchase of up to 50,000 shares (Option Shares) of the Company’s Common Stock at $3.65 per share. As permitted 
by  the 2017  Stock  Option  Plan, Mr.  Naccarato  elected  to pay  the  exercise  price  of  the  Option  Shares  by having  the  Company 
withhold from the Option Shares a number of shares having a fair market value equal to the aggregate exercise price of $182,500. 
Since  the  fair  market  value  of  the  Company’s  Common  Stock  on  May  22,  2023,  (as  determined  in  accordance  with  the  2017 
Stock Option Plan) was $11.05 per share, the Company withheld 16,516 shares of Common Stock ($182,500 divided by $11.05) 
to  pay  the  aggregate  exercise  price  for  the  Option  Shares  and  issued  33,484  shares  to  Mr.  Naccarato.  Realized  value  on  this 
exercise was determined based on the difference between the (a) exercise price ($3.65) per share of the Option Shares multiplied  
by the 50,000 Option Shares exercised, and (b) the market value ($11.05) on the date of exercise of the Option Shares times the 
50,000 Option Shares exercised.   

(3) On May 22, 2023, Dr. Louis Centofanti exercised 100% of his ISO granted to him on July 27, 2017 under the Company’s 2017 
Stock  Plan  for  the  purchase  of  up  to  50,000  shares  (Option  Shares)  of  the  Company’s  Common  Stock  at  $3.65  per  share.  As 
permitted  by  the  2017 Stock  Option Plan,  Dr.  Centofanti  elected to  pay  the  exercise  price  of  the Option  Shares  by  having  the 
Company withhold from the Option Shares a number of shares having a fair market value equal to the aggregate exercise price of 
$182,500. Since the fair market value of the Company’s Common Stock on May 22, 2023, (as determined in accordance with the 
2017 Stock Option Plan) was $11.05 per share, the Company withheld 16,516 shares of Common Stock ($182,500 divided by 
$11.05) to pay the aggregate exercise price for the Option Shares and issued 33,484 shares to Dr. Centofanti. Realized value on 
this  exercise  was  determined  based  on  the  difference  between  the  (a)  exercise  price  ($3.65)  per  share  of  the  Option  Shares 
multiplied  by the 50,000 Option Shares exercised, and (b) the market value ($11.05) on the date of exercise of the Option Shares 
times the 50,000 Option Shares exercised. 

(4) On  March  28,  2023,  Mr.  Lombardo  exercised  100%  of  his  remaining  ISO  granted  to  him  on  October  19,  2017  under  the 
Company’s 2017 Stock plan for the purchase of up to 12,000 shares (Option shares) of the Company’s Common Stock at $3.60 
per share. As permitted by the 2017 Stock Option Plan, Mr. Lombardo elected to pay the exercise price of the Option Shares by 
having  the  Company  withhold  from  the  Option  Shares  a  number  of  shares  having  a  fair  market  value  equal  to  the  aggregate

exercise price of $43,200. Since the fair market value of the Company’s Common Stock on March 28, 2023, (as determined in 
accordance  with  the  2017  Stock  Option  Plan)  was  $11.995  per  share,  the  Company  withheld  3,602  shares  of  Common  Stock 
($43,200 divided by $11.995) to pay the aggregate exercise price for the Option Shares and issued 8,398 shares to Mr. Lombardo. 
Realized value on this exercise was determined based on the difference between the (a) exercise price ($3.60) per share of the 
Option Shares multiplied  by the 12,000 Option Shares exercised, and (b) the market value ($11.995) on the date of exercise of 
the Option Shares times the 12,000 Option Shares exercised. 

(5) On  October 2,  2023,  Mr.  Grondin  exercised  100% of  an  ISO granted  to him  on  October  19,  2017  under the  Company’s  2017 
Stock Option Plan for the purchase of up to 20,000 shares (Option Shares) of the Company’s Common Stock at $3.60 per share. 
As permitted by the 2017 Stock Option Plan, Mr. Grondin elected to pay the exercise price of the Option Shares by having the 
Company withhold from the Option Shares a number of shares having a fair market value equal to the aggregate exercise price of 
$72,000. Since the fair market value of the Company’s Common Stock on October 2, 2023, (as determined in accordance with the 
2017  Stock  Option  Plan)  was  $10.115  per  share,  the  Company  withheld  7,118  shares  of  Common  Stock  ($72,000  divided  by 
$10.115)  to  pay  the  aggregate  exercise  price  of  the  option  and  issued  12,882  shares  to  Mr.  Grondin.  Realized  value  on  this 
exercise was determined based on the difference between the (a) exercise price ($3.60) per share of the Option Shares multiplied  
by the 20,000 Option Shares exercised, and (b) the market value ($10.115) on the date of exercise of the Option Shares times the 
20,000 Option Shares exercised. 

(6) On  October  2,  2023,  Mr.  Grondin  exercised  the  vested  portion  of  an  ISO  granted  to  him  on  January  17,  2019  under  the 
Company’s 2017 Stock Option Plan for the purchase of 8,000 shares (Option Shares) of the Company’s Common Stock at $3.15 
per share. As permitted by the 2017 Stock Option Plan, Mr. Grondin elected to pay the exercise price of the Option Shares by 
having  the  Company  withhold  from  the  Option  Shares  a  number  of  shares  having  a  fair  market  value  equal  to  the  aggregate 
exercise price of $25,200. Since the fair market value of the Company’s Common Stock on October 2, 2023, (as determined in 
accordance  with  the  2017  Stock  Option  Plan)  was  $10.115  per  share,  the  Company  withheld  2,491  shares  of  Common  Stock 
($25,200 divided by $10.115) to pay the aggregate exercise price of the option and issued 5,509 shares to Mr. Grondin. Realized 
value  on  this  exercise  was  determined  based  on  the  difference  between  the  (a)  exercise  price  ($3.15)  per  share  of  the  Option 
Shares multiplied  by the 8,000 Option Shares exercised, and (b) the market value ($10.115) on the date of exercise of the Option 
Shares times the 8,000 Option Shares exercised. 

Employment Agreements  
On April 20, 2023, upon recommendation by the Compensation Committee and approval by the Board, the 
Company  entered  into  employment  agreements  with  each  of  Mark  Duff,  President  and  CEO,  Ben 
Naccarato, EVP and CFO, Dr. Louis Centofanti, EVP of Strategic Initiatives, Andrew Lombardo, EVP of 
Nuclear  and  Technical  Services,  and  Richard  Grondin,  EVP  of  Waste  Treatment  Operations  (collectively 
the  “New  Employment  Agreements”  and  each,  individually,  a  “New  Employment  Agreement”).”  The 
Company had previously entered into employment agreements with each of Mark Duff, Ben Naccarato, Dr. 
Louis Centofanti, Andrew Lombardo and Richard Grondin on July 22, 2020, all five of which agreements 
were due to expire on July 22, 2023, but which were terminated effective April 20, 2023 upon the execution 
of the New Employment Agreements.  

Each of the New Employment Agreements, which are substantially identical except for compensation, are 
effective  April  20,  2023.  Under  the  New  Employment  Agreements,  each  of  these  executive  officers  is 
provided  an  annual  salary,  which  annual  salary  may  be  increased  from  time  to  time,  but  not  reduced,  as 
determined  by  the  Compensation  Committee.  In  addition,  each  of  these  executive  officers  is  entitled  to 
participate in the Company’s broad-based benefits plans and to certain performance compensation payable 
under separate MIPs as approved by the Company’s Compensation Committee and the Company’s Board.  
The  Company’s  Compensation  Committee and  the  Board approved individual  2023  MIPs  on January 19, 
2023  (which  were  effective  January  1,  2023  and  applicable  for  the  2023  fiscal  year)  for  each  of  the 
executive officers (see discussion of each of the 2023 MIPs below under “2023 MIPs”).  

Each  of  the  New  Employment  Agreements  is  effective  for  three  years  from  April  20,  2023  (the  “Initial 
Term”) unless earlier terminated by the Company or by the executive officer. At the end of the Initial Term 
of each New Employment Agreement, each New Employment Agreement will automatically be extended 
for one additional year, unless at least six months prior to the expiration of the Initial Term, the Company or 
the executive officer provides written notice not to extend the terms of the New Employment Agreement. 
Mr.  Andrew  Lombardo  retired  from  the  position  of  EVP  of  Nuclear  and  Technical  Services  effective 
January  1,  2024.  Upon  Mr.  Lombardo’s  retirement  from  the  position  of  EVP  of  Nuclear  and  Technical 
Services, he no longer was an executive officer of the Company. Upon his retirement as EVP of Nuclear 
and Technical Services, his employment agreement dated April 20, 2023, was terminated effective January 
1,  2024.  Mr.  Lombardo  remains  employed  by  the  Company  at  a  reduced  capacity,  and  assists  with  the 
transition of his former responsibilities as well as contributing to certain business development matters.

Pursuant to the New Employment Agreements, if the executive officer’s employment is terminated due to 
death, disability or for cause (as defined in the agreements), the Company will pay to the executive officer 
or  to  his  estate  an  amount  equal  to the  sum  of  any  unpaid  base  salary  and  accrued  unused  vacation  time 
through the date of termination and any benefits due to the executive officer under any employee benefit 
plan  (the  “Accrued  Amounts”)  plus  any  performance  compensation  payable  pursuant  to  the  executive 
officer’s MIP with respect to the fiscal year immediately preceding the date of termination. In the event that 
an  executive  officer’s  employment  is  terminated  due  to  death,  the  Company  will  also  pay  a  lump-sum 
payment  (the  “Cash  Medical  Continuation  Benefit”)  equal  to  eighteen  times  the  monthly  premium  that 
would be required to be paid, pursuant to the Consolidated Omnibus Budget Reconciliation Act of 1985, as 
amended  (“COBRA”),  to  continue  group  health  coverage  for  the  executive  officer’s  eligible  covered 
dependents  in  effect  on  the  date  of  the  executive  officer’s  termination  of  employment,  based  on  the 
premium  for  the  first  month  of  COBRA  coverage.  Such  cash  payment  will  be  taxable  and  will  be  made 
regardless  of  whether  the  executive  officer’s  eligible  covered  dependents  elect  COBRA  continuation 
coverage.  

If the executive officer terminates his employment for “good reason” (as defined in the agreements) or is 
terminated  by  the  Company  without  cause  (including  any  such  termination  for  “good  reason”  or  without 
cause within 24 months after a Change in Control (as defined in the agreements), the Company will pay the 
executive officer Accrued Amounts, (a) two years of full base salary, plus (b) (i) two times the performance 
compensation  (under  the  executive  officer’s  MIP)  earned  with  respect  to  the  fiscal  year  immediately 
preceding the date of termination provided the performance compensation earned with respect to the fiscal 
year  immediately  preceding  the  date  of  termination  has  not  yet  been  paid,  or  (ii)  if  performance 
compensation  earned  with  respect  to  the  fiscal  year  immediately  preceding  the  date  of  termination  has 
already  been  paid  to  the  executive  officer,  the  executive  officer  will  be  paid  an  additional  year  of  the 
performance  compensation  earned  with  respect  to  the  fiscal  year  immediately  preceding  the  date  of 
termination,  and  (c)  the  Cash  Medical  Continuation  Benefit.  If  the  executive  officer  terminates  his 
employment  for  a  reason  other  than  for  good  reason,  the  Company  will  pay  to  the  executive  officer  an 
amount  equal  to  the  Accrued  Amounts  plus  any  performance  compensation  payable  pursuant  to  the  MIP 
applicable to such executive officer.    

Additionally,  in  the  event  of  a  Change  in  Control  (as  defined  in  the  agreements),  all  outstanding  stock 
options to purchase the common stock held by the executive officer will immediately become exercisable in 
full  commencing  on  the  date  of  termination  through  the  original  term  of  the  options.  In  the  event  of  the 
death of an executive officer, all outstanding stock options to purchase common stock held by the executive 
officer  will  immediately  become  exercisable  in  full  commencing  on  the  date  of  death,  with  such  options 
exercisable  for  the  lesser  of  the  original  option  term  or  twelve  months  from  the  date  of  the  executive 
officer’s death. In the event an executive officer terminates his employment for “good reason” (as defined in 
the agreements) or is terminated by the Company without cause, all outstanding stock options to purchase 
common stock held by the officer will immediately become exercisable in full commencing on the date of 
termination, with such options exercisable for the lesser of the original option term or within 60 days from 
the  date  of  the  executive  officer’s  date  of  termination.  Severance  benefits  payable  with  respect  to  a 
termination  (other  than  Accrued  Amounts)  shall  not  be  payable  until  the  termination  constitutes  a 
“separation from service” (as defined under Treasury Regulation Section 1.409A-1(h)).  

Potential Payments Upon Termination or Change in Control 
The  following  table  sets  forth  the  potential  (estimated)  payments  and  benefits  to  which  each  executive 
officer would be entitled upon termination of employment by the executive officer for “good reason” or by 
the Company “without cause,” or following a Change in Control of the Company, as specified under each of 
their respective Employment Agreements with the Company, assuming each circumstance described below 
occurred on December 31, 2023, the last day of our most recent fiscal year. Such potential payments include 
any  Accrued  Amounts (accrued  base  salary  earned  for  2023  but  paid in  2024, as  well  as  accrued  unused 
vacation/sick  time  and  other  vested  benefits  under  the  Company  plans  in  which  the  executive  officer 
participates). The executive officer is not entitled to payment of any benefits upon termination for cause or 
resignation without good reason other than for Accrued Amounts.

Benefit is calculated based on the difference between the exercise price of each option and the market value of the Company’s 
Common  Stock  per  share  (as  reported  on  the  Nasdaq)  at  December  31,  2023  times  the  number  of  options  outstanding  at 
December 31, 2023. Benefit excludes options which were out-of-the-money at December 31, 2023. 

Represents a lump-sum payment equal to eighteen times the monthly premium that would be required to be paid to continue 
group health coverage for the executive officer’s eligible covered dependents in effect on the date of the executive officer’s 
termination of employment as defined in the employment agreement, 

2023 Executive Compensation Components  
For  the  fiscal  year  ended  December 31,  2023,  the  principal  components  of  compensation  for  executive 
officers were:  

  base salary; 
  performance-based incentive compensation; 
 
 
  perquisites.  

long term incentive compensation; 
retirement and other benefits; and 

Based  on  the  amounts  set  forth  in  the  Summary  Compensation  table,  during  2023,  salary  accounted  for 
approximately  52.4%  of  the  total  compensation  of  our  NEOs,  while  equity  option  awards,  MIP 
compensation, bonus and other compensation accounted for approximately 47.6% of the total compensation 
92 

 
 
 
 
 
 
 
 
of the NEOs. 

Base Salary  
The NEOs, other officers, and other employees of the Company receive a base annual salary. Base salary 
ranges  for  executive  officers  are  determined  for  each  executive  based  on  his  or  her  position  and 
responsibility by using market data and comparisons to similar companies within the business segments in 
which the Company operates.    

During its review of base salaries for executives, the Compensation Committee primarily considers:  

  market  data  and  comparisons  to  similar  companies  within  the  business  segments  in  which  the 

Company operates; 

 

 

internal review of the executive’s compensation, both individually and relative to other officers; and 

individual performance of the executive. 

Salary levels are typically considered annually as part of the performance review process as well as upon a 
promotion or other change in job responsibility. Merit-based salary increases for executives are based on the 
Compensation  Committee’s  assessment  of  the  individual’s  performance.  The  base  salary  and  potential 
annual base salary adjustments for the NEOs are set forth in their respective employment agreements. On 
October 19, 2023, the Compensation Committee and the Board approved a base salary increase adjustment, 
effective  January  1,  2024,  of  seven  percent  for  the  CEO  and  five  percent  for  each  of  the  CFO,  EVP  of 
Strategic Initiatives, and the EVP of Waste Treatment Operations. The following reflects the base salary for 
each of the NEOs on January 1, 2024, after the base salary increase: $417,155 for the CEO; $332,811 for 
the  CFO;  $277,346  for  the  EVP  of  Strategic  Initiatives;  and  $285,267  for  the  EVP  of  Waste  Treatment 
Operations. 

Performance-Based Incentive Compensation  
The  Compensation  Committee  has  the  latitude  to  design  cash  and  equity-based  incentive  compensation 
programs  to  promote  high performance  and  achievement  of  our  corporate  objectives  by  directors  and  the 
NEOs,  encourage  the  growth  of  stockholder  value  and  enable  employees  to  participate  in  our  long-term 
growth  and  profitability.  The  Compensation  Committee  may  grant  stock  options  and/or  performance 
bonuses.  In  granting  these  awards,  the  Compensation  Committee  may  establish  any  conditions  or 
restrictions it deems appropriate.  In addition, the CEO has discretionary authority to grant stock options to 
certain high-performing executives or officers, subject to the approval of the Compensation Committee. The 
exercise price for each stock option granted is at or above the market price of our Common Stock on the 
date of grant. Stock options may be awarded to newly hired or promoted executives at the discretion of the 
Compensation Committee. Grants of stock options to eligible newly hired executive officers are generally 
made at the next regularly scheduled Compensation Committee meeting following the hire date.  

2023 MIPs 
On  January  19,  2023,  the  Compensation  Committee  and  the  Board  approved  individual  MIPs  for  the 
calendar year 2023 for each of the NEOs. Each of the MIPs was effective January 1, 2023.  

The performance compensation payable under each MIP was based upon meeting certain of the Company’s 
separate  target  objectives  during  2023  as  described  in  each  of  the  MIPs  below,  provided,  however,  no 
performance  compensation  was  to  be  paid  for  attaining  any  of  the  Company’s  separate  target  objectives 
unless  a  minimum  of  75%  of  the  EBITDA  target  objective  was  achieved.  The  Compensation  Committee 
believes performance compensation payable under each of the MIPs should be based on achievement of at 
least  75%  of  EBITDA  (earnings  before  interest,  taxes,  depreciation  and  amortization),  a  non-U.S.  GAAP 
(accounting  principles  generally  accepted  in  the  United  States  of  America)  financial  measurement,  as  the 
Company believes that this target provides a better indicator of operating performance as it excludes certain 
non-cash items. EBITDA has certain limitations as it does not reflect all items of income or cash flows that 
affect the Company’s financial performance under U.S. GAAP.  

93 

 
 
 
  
 
 
 
 
 
 
In formulating certain targets set forth in the MIPs, the Compensation Committee and the Board considered 
the  Board-approved  budget  for  2023,  economic  conditions  (continued  potential  impact  of  COVID-19), 
forecasts  for  2023  government  spending,  as  well  as  the  Compensation  Committee’s  expectation  for 
performance that in its estimation would warrant payment of incentive cash compensation.  

Performance compensation amounts earned under the 2023 MIPs are to be paid on or about 90 days after 
year-end, or sooner, based on finalization of our audited financial statements for 2023. For 2023, a total of 
approximately $750,000 was earned by the NEOs under the MIPs. See “Compensation Earned Under 2023 
MIPs” below for amount earned by each NEO under his respective MIP. 

The Compensation Committee retained the right to modify, change or terminate each MIP and may adjust 
the various target amounts described below, at any time and for any reason. 

The total to be paid to the NEOs under the 2023 MIPs may not exceed 50% of the Company’s pre-tax net 
income prior to the calculation of performance compensation. 

The following schedules reflect performance compensation that was payable under each of the 2023 MIPs, 
along with a description of the target objectives.

(1)  Revenue was defined as the total consolidated third-party top line revenue as publicly reported in the 
Company’s  2023  financial  statements.  The  percentage  achieved  was  determined  by  comparing  the 
actual consolidated revenue for 2023 to the Board-approved revenue target for 2023.   

(2)  EBITDA was defined as earnings before interest, taxes, depreciation, and amortization from continuing 
and  discontinued  operations.  The  percentage  achieved  was  determined  by  comparing  the  actual 
EBITDA to the Board-approved EBITDA target for 2023.    

(3)  The Health and Safety Incentive target was based upon the actual number of Worker’s Compensation 
Lost Time Accidents (“WCLTA”), as provided by the Company’s Worker’s Compensation carrier. For 
the EVP of Nuclear and Technical Services and the EVP of Waste Treatment Operations, the incentive 
target  was  based  on  actual  number  of  WCLTA  in  the  Services  and  Treatment  Segments  only, 
respectively.  The  Corporate  Controller  submitted  a  report  on  a  quarterly  basis  documenting  and 
confirming  the  number  of  Worker’s  Compensation  Lost  Time  Accidents,  supported  by  the  Worker’s 
Compensation Loss Report provided by the company’s carrier or broker.  Such claims were identified 
on the loss report as “indemnity claims.” The following number of Worker’s Compensation Lost Time 
Accidents  and  corresponding  performance  target  thresholds  was  established  for  the  annual  Incentive 
Compensation Plan calculation for 2023.

(4)  Permits or License Violations incentive was earned/determined according to the scale set forth below:  
An “official notice of non-compliance” was defined as an official communication during 2023 from a 
local, state,  or federal regulatory  authority alleging  one  or more violations of  an  otherwise  applicable 
Environmental,  Health  or  Safety  requirement  or  permit  provision,  which  resulted  in  a  facility’s 
implementation of corrective action(s) which included a material financial obligation, as determined by 
the Company’s Board of Directors in their sole discretion, to the Company .

(5)  CPI  incentive  was  earned/determined  by  maintaining  project  performance  metrics  for  all  Firm  Fixed 
Price task orders and projects to include monitoring CPI based on recognized earned value calculations. 
As  defined  through  monthly  project  reviews,  all  CPI  metrics  should  exceed  1.0  for  Nuclear  Services 
Projects.  A  cumulative  CPI  (CCPI)  was  calculated from  all  fixed  cost  contracts.  The following  CCPI 
and  corresponding  performance  target  thresholds  were  established  for  annual  incentive  compensation 
plan calculation for 2023.

2024 MIPs 
On  January  18,  2024,  the  Compensation  Committee  and  the  Board  (with  Mr.  Mark  Duff  and  Dr.  Louis 
Centofanti abstaining) approved individual MIPs for the calendar year 2024 for each of the NEOs. Each of 
the MIPs is effective January 1, 2024.  

The  performance  compensation  payable  under each MIP  is  based upon meeting  certain  of  the  Company’s 
separate  target  objectives  during  2024  as  described  in  each  of  the  MIPs  below,  provided,  however,  no 
performance compensation will be paid for attaining any of the Company’s separate target objectives unless 
a  minimum  of  75%  of  the  EBITDA  target  objective  is  achieved.  In  formulating  such  targets,  the 
Compensation  Committee  and  the  Board  considered  2023  results,  the  Board-approved  budget  for  2024, 
economic  conditions,  forecasts  for  2024  government  spending,  as  well  as  the  Compensation  Committee’s 
expectation for performance that in its estimation would warrant payment of incentive cash compensation 

Performance compensation amounts under the 2024 MIPs are to be paid on or about 90 days after year-end, 
or sooner, based on finalization of our audited financial statements for 2024.  

The Compensation Committee retains the right to modify, change or terminate each MIP and may adjust the 
various target amounts described below, at any time and for any reason. 

The total to be paid to the NEOs under the MIPs shall not exceed 50% of the Company’s pre-tax net income 
prior to the calculation of performance compensation. 

The following schedules reflect performance compensation payable under each of the MIPs, along with a

(1)  Revenue  is  defined  as  the  total  consolidated  third-party  top  line  revenue  as  publicly  reported  in  the 
Company’s 2024 financial statements. The percentage achieved is determined by comparing the actual 
consolidated revenue for 2024 to the Board-approved revenue target for 2024.   

(2)  EBITDA  is  defined  as  earnings before interest,  taxes,  depreciation, and  amortization  from  continuing 
and discontinued operations. The percentage achieved is determined by comparing the actual EBITDA 
to the Board-approved EBITDA target for 2024.    

(3)  Regulatory  Filing  Incentive  Target  is  based  on  meeting  all  deadlines  (including  allowable  extension 
granted  by  the  SEC)  for  the  Form  10-K,  Form  10-Q  and  8-Ks  required  by  SEC  (Securities  and 
Exchange Commission). 

(4)  The Health and Safety Incentive target was based upon the actual number of Worker’s Compensation 
Lost Time Accidents (“WCLTA”), as provided by the Company’s Worker’s Compensation carrier. For 
the EVP of Waste Treatment Operations, the incentive target is based on actual number of WCLTA in 
the  Treatment  Segments  only.  The  Corporate  Controller  will  submit  a  report  on  a  quarterly  basis 
documenting and  confirming  the  number  of  Worker’s  Compensation  Lost  Time  Accidents, supported 
by the Worker’s Compensation Loss Report provided by the company’s carrier or broker.  Such claims 
will  be  identified  on  the  loss  report  as  “indemnity  claims.”    The  following  number  of  Worker’s 
Compensation  Lost  Time  Accidents  and  corresponding  performance  target  thresholds  has  been 
established for the annual Incentive Compensation Plan calculation for 2024.

Long-Term Incentive Compensation  

Employee Stock Option Plans 
The 2017 Stock Option Plan (“2017 Plan”) encourages participants to focus on long-term performance and 
provides an opportunity for executive officers and certain designated key employees to increase their stake 
in the Company. Stock options succeed by delivering value to executives only when the value of our stock 
increases.  The  2017  Plan  authorizes  the  grant  of  Non-Qualified  Stock  Options  (“NQSOs”)  and  Incentive 
Stock Options (“ISOs”) for the purchase of our Common Stock.   

The 2017 Plan was adopted to: 

 

enhance  the  link  between  the  creation  of  stockholder  value  and  long-term  executive  incentive 
compensation; 

  provide an opportunity for increased equity ownership by executives; and 

  maintain competitive levels of total compensation;  

Stock  option  award  levels  are  determined  based  on  market  data,  vary  among  participants  based  on  their 
positions  with  the  Company  and  are  granted  generally  at  the  Compensation  Committee’s  regularly 
scheduled July or August meeting. Newly hired or promoted executive officers who are eligible to receive 
options  are  generally  awarded  such  options  at  the  next  regularly  scheduled  Compensation  Committee 
meeting following their hire or promotion date.  

Options  are  awarded  with  an  exercise  price  equal  to  or  not  less  than  the  closing  price  of  the  Company’s 
Common Stock on the date of the grant as reported on the Nasdaq.  In certain limited circumstances, the 
Compensation  Committee may  grant  options  to  an  executive  at  an  exercise  price in  excess  of the closing 
price of the Company’s Common Stock on the grant date.  

The Company’s NEOs have outstanding options from the Company’s 2017 Plan (See “Item 11 – Executive 
Compensation – Outstanding Equity Awards at Fiscal Year-End - Outstanding Equity Awards at December 
31, 2023,” for outstanding options under the 2017 Plan for each of our NEOs).  

In  cases  of  termination  of  an  executive  officer’s  employment  due  to  death,  by  the  executive  for  “good 
reason,” by the Company without cause, and due to a “change of control,” all outstanding stock options to 
purchase  common  stock  held  by  the  executive  officer  will  immediately  become  exercisable  in  full  (see 

101 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
further  discussion  of  the  exercisability  term  of  these  options  in  each  of  these  circumstances  in 
“EXECUTIVE  COMPENSATION  –  Employment  Agreements”).  Otherwise,  vesting  of  option  awards 
ceases upon termination of employment and exercise right of the vested option amount ceases upon three 
months from termination of employment except in the case of retirement (subject to a six-month limitation) 
and disability (subject to a one-year limitation). 

Accounting for Stock-Based Compensation  
We  account  for  stock-based  compensation  in  accordance  with  ASC  718,  “Compensation  –  Stock 
Compensation.”  ASC  718 establishes  accounting standards  for  entity  exchanges  of equity instruments  for 
goods or services.  It also addresses transactions in which an entity incurs liabilities in exchange for goods 
or services that are based on the fair value of the entity’s equity instruments or that may be settled by the 
issuance of those equity instruments. ASC 718 requires all stock-based payments to employees, including 
grants of employee stock options, to be recognized in the income statement based on their fair values. The 
Company  uses  the  Black-Scholes  option-pricing  model  to  determine the  fair-value  of  stock-based  awards 
which requires subjective assumptions. Assumptions used to estimate the fair value of stock options granted 
include the exercise price of the award, the expected term, the expected volatility of the Company’s stock 
over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected 
annual dividend yield. We recognize stock-based compensation expense using a straight-line amortization 
method over the requisite period, which is the vesting period of the stock option grant.  

Retirement and Other Benefits  

401(k) Plan 
The Company adopted the Perma-Fix Environmental Services, Inc. 401(k) Plan (the “401(k) Plan”) in 1992, 
which  is  intended  to  comply  with  Section  401  of  the  Internal  Revenue  Code  and  the  provisions  of  the 
Employee Retirement Income Security Act of 1974. All full-time employees who have attained the age of 
18 are eligible to participate in the 401(k) Plan. Eligibility is immediate upon employment but enrollment is 
only allowed during four quarterly open periods of January 1, Apri1 1, July 1, and October 1. Participating 
employees may make annual pretax contributions to their accounts up to 100% of their compensation, up to 
a maximum amount as limited by law. At our discretion, we may make matching contributions based on the 
employee’s  elective  contributions.  Company  contributions  vest  over  a  period  of  five  years.  In  2023,  the 
Company contributed approximately $576,000 in 401(k) matching funds, of which approximately $34,000 
was  for  our  NEOs  (see  the  “Summary  Compensation”  table  in  this  section  for  401(k)  matching  fund 
contributions made for the NEOs for 2023).  

Perquisites and Other Personal Benefits  
The  Company  provides  executive  officers  with  limited  perquisites  and  other  personal  benefits 
(health/disability/life insurance) that the Company and the Compensation Committee believe are reasonable 
and  consistent  with  its  overall  compensation  program  to  better  enable  the  Company  to  attract  and  retain 
superior  employees  for  key  positions.  The  Compensation  Committee  periodically  reviews  the  levels  of 
perquisites and other personal benefits provided to executive officers. The executive officers are provided 
an auto allowance.  

Compensation of Directors 
Directors  who  are  employees  receive  no  additional  compensation  for  serving  on  the  Board  or  its 
committee(s).  In  2023,  the  Company  provided  the  following  annual  compensation  to  each  non-employee 
director for service on the Board and the committee(s) for which he/she serves:    

 
 
 
 

a quarterly fee of $11,500; 
an additional quarterly fee of $8,750 to the Chairman of the Board; 
an additional quarterly fee of $6,250 to the Chairman of the Audit Committee; 
an  additional  quarterly  fee  of  $3,125  to  the  Chairman  of  each  of  the  Compensation  Committee,  the 
Governance and Nominating Committee, and the Strategic Committee. The Chairman of the Board was 
not  eligible  to  receive  a  quarterly  fee  for  serving  as  the  Chairman  of  any  the  aforementioned 
committees; 

102 

 
  
 
 
 
 
 
 

 

 

an  additional  $1,250  to  each  Audit  Committee  member  (excluding  the  Chairman  of  the  Audit 
Committee);  
an additional quarterly fee of $500 to each member of the Compensation Committee, the Governance 
and Nominating Committee, and the Strategic Committee. Such fee was payable only if the member did 
not also serve as the Chairman of any other standing committees or as the Chairman of the Board; and 
a fee of $1,000 for each in-person board meeting attended and a $500 fee for meeting attendance via 
conference call; 

Under the 2003 Outside Directors Stock Plan (“2003 Outside Directors Plan”), each director may elect to 
have either 65% or 100% of such fees payable in Common Stock, with the balance, if any, payable in cash.  
Each non-employee director was also granted a NQSO to purchase up to 10,000 shares of Common Stock 
upon reelection at the 2023 Annual Meeting of Stockholders, with vesting at 25% per year, beginning on the 
first anniversary date of the grant, with each option having a 10-year term.  

Dr. Louis Centofanti, a current member of the Board, is not eligible to receive compensation for his service 
as a director of the Company as he is an employee of the Company. As the Company’s President and CEO, 
Mr. Duff, who was elected by the Company’s Board as a Board member effective April 20, 2023, also is not 
eligible  to  receive  compensation  for  his  service  as  a  director  of  the  Company  (see  “Summary 
Compensation” table in this section for each of Dr. Centofanti’s and Mark Duff’s annual salary and other 
compensation as an employee of the Company).  

The table below summarizes the director compensation expenses recognized by the Company for director 
options and stock awards (resulting from fees earned) for the year ended December 31, 2023.  The terms of 
the 2003 Outside Directors Plan are further described below under “2003 Outside Directors Plan.”

(1)  Under the 2003 Outside Directors Plan, each director elects to receive 65% or 100% of the director’s fees in shares of our 
Common Stock.  The amounts set forth above represent the portion of the director’s fees paid in cash and exclude the value of 
the director’s fee elected to be paid in Common Stock under the 2003 Outside Directors Plan, which values are included under 
“Stock Awards.” 

(2) 

(3) 

(4) 

The number of shares of Common Stock comprising stock awards granted under the 2003 Outside Directors Plan is calculated 
based on 75% of the closing market value of the Common Stock as reported on the Nasdaq on the business day immediately 
preceding the date that the quarterly fee is due. Such shares are fully vested on the date of grant. The value of the stock award 
is based on the market value of our Common Stock at each quarter end times the number of shares issuable under the award.  
The amount shown is the fair value of the Common Stock on the date of the award.     

Reflects options granted under the Company’s 2003 Outside Directors Plan resulting from re-election to the Board on July 20, 
2023. Options are for a 10-year period with an exercise price of $9.81 per share and vest 25% per year, beginning on the first 
anniversary date of the grant. The value of the option award for each outside director is calculated based on the fair value of 
the  option  per  share  (approximately  $6.46)  on  grant  date  times  the  number  of  options  granted,  which  was  10,000  for  each 
director, pursuant to ASC 718, “Compensation – Stock Compensation.”.  

The following table reflects the aggregate number of outstanding NQSOs held by the Company’s directors at December 31, 
2023. As an employee of the Company or its subsidiaries, neither Dr. Centofanti nor Mark Duff is eligible to participate in the

2003 Outside Directors Plan 
We believe that it is important for our directors to have a personal interest in our success and growth and for 
their  interests  to  be  aligned  with  those  of  our  stockholders;  therefore,  under  our  2003  Outside  Directors 
Plan, each outside director is granted a 10-year NQSO to purchase up to 20,000 shares of Common Stock on 
the  date  such  director  is  initially  elected  to  the  Board,  and  receives  on  each  re-election  date  a  NQSO  to 
purchase up to another 10,000 shares of our Common Stock, with the exercise price being the fair market 
value  of  the  Common  Stock  preceding  the  option  grant  date.  Common  Stock  shares  subject  to  option 
granted  vest  at  25%  per  year,  beginning  on  the  first  anniversary  date  of  the  grant  and  no  option  shall  be 
exercisable after the expiration of ten years from the date the option is granted. As of December 31, 2023, 
options to purchase 300,000 shares of Common Stock were outstanding under the 2003 Outside Directors 
Plan, of which 142,500 were vested. 

As a member of the Board, each director may elect to receive either 65% or 100% of his or her director's fee 
in shares of our Common Stock. The number of shares received by each director is calculated based on 75% 
of the fair market value of the Common Stock determined on the business day immediately preceding the 
date that the quarterly fee is due. The balance of each director’s fee, if any, is payable in cash. In 2023, fees 
earned by our outside directors totaled approximately $572,000. 

In the event of a “change of control” (as defined in the 2003 Outside Directors Plan) or by reason of the 
director’s death or Disability (as defined), each outstanding stock option and stock award shall immediately 
become exercisable in full notwithstanding the vesting or exercise provisions contained in the stock option 
agreement.   

ITEM 12. 

SECURITY  OWNERSHIP  OF  CERTAIN  BENEFICIAL  OWNERS  AND 
MANAGEMENT AND RELATED STOCKHOLDER MATTERS 

Security Ownership of Certain Beneficial Owners 
Schelhammer Capital Bank AG, a banking institution regulated by the banking regulations of Austria, has 
represented to the Company that as of February 1, 2024, it holds of record as a nominee for, and as an agent 
of, certain accredited investors, 1,837,572 shares of our Common Stock.  None of the Common Stock held 
by Schelhammer Capital Bank AG for the account of any single investor represents more than 4.9% of our 
Common Stock and, to the best knowledge of Schelhammer Capital Bank AG, as far as stocks held by such 
investors in accounts with Schelhammer Capital Bank AG, none of such investors act together as a group or 
otherwise act in concert for the purpose of voting on matters subject to the vote of our stockholders or for 
purpose  of  disposition  or  investment  of  such  stock.  Additionally,  the  investors  for  whom  Schelhammer 
Capital  Bank  AG  acts  as  nominee  with respect  to  such  shares maintain full  voting  and  dispositive  power 
over  the  Common  Stock  beneficially  owned  by  such  investors,  and  Schelhammer  Capital  Bank  AG  has 
neither  voting  nor  investment  power  over  such  shares.  Accordingly,  Schelhammer  Capital  Bank  AG 
believes that (i) it is not the beneficial owner, as such term is defined in Rule 13d-3 of the Exchange Act, of 
the shares of Common Stock registered in Schelhammer Capital Bank AG’s name because (a) Schelhammer 
Capital  Bank  AG  holds  the  Common  Stock  as  a  nominee  only,  (b)  Schelhammer  Capital  Bank  AG  has 
104 

 
 
     
     
   
     
     
     
     
     
     
   
 
 
 
 
 
neither  voting  nor  investment  power  over  such  shares,  and  (c)  Schelhammer  Capital  Bank  AG  has  not 
nominated or sought to nominate, and does not intend to nominate in the future, any person to serve as a 
member of our Board; and (ii) it is not required to file reports under Section 16(a) of the Exchange Act or to 
file either Schedule 13D or Schedule 13G in connection with the shares of our Common Stock registered in 
the name of Schelhammer Capital Bank AG. 

Notwithstanding the previous paragraph, if Schelhammer Capital Bank AG's representations to us described 
above are incorrect or if the investors for whom Schelhammer Capital Bank AG acts as nominee are acting 
as a group, then Schelhammer Capital Bank AG or a group of such investors could be a beneficial owner of 
more than 5% of our voting securities. If Schelhammer Capital Bank AG was deemed the beneficial owner 
of  such  shares,  the  following  table  sets  forth  information  as  to  the  shares  of  voting  securities  that 
Schelhammer Capital Bank AG may be considered to beneficially own on February 1, 2024:

plus  the  number  of  shares  of  Common  Stock  which  Schelhammer  Capital  Bank  AG,  as  agent  for  certain 
accredited investors, has the right to acquire within 60 days, which is none.   

(+)  This  amount  is the  number  of  shares  that  Schelhammer  Capital  Bank  AG  has  represented  to  us  that  it 
holds of record as nominee for, and as an agent of, certain accredited investors.  As of February 1, 2024, the 
date  of  Schelhammer  Capital  Bank  AG’s  representations  to  us,  Schelhammer  Capital  Bank  AG  has  no 
warrants  or  options  to  acquire,  as  agent  for  certain  investors,  additional  shares  of  our  Common  Stock. 
Although Schelhammer Capital Bank AG is the record holder of the shares of Common Stock described in 
this note, Schelhammer Capital Bank AG has advised us that it does not believe it is a beneficial owner of 
the Common Stock or that it is required to file reports under Section 16(a) or Section 13(d) of the Exchange 
Act.  Schelhammer Capital Bank AG has advised us that it (a) holds the Common Stock as a nominee only 
and that it does not exercise voting or investment power over the Common Stock held in its name and that 
no one investor for which it holds our Common Stock holds more than 4.9% of our issued and outstanding 
Common Stock and (b) has not nominated, and has not sought to nominate, and does not intend to nominate 
in  the  future,  any  person  to  serve  as  a  member  of  our  Board.  Accordingly,  we  do  not  believe  that

Beneficial ownership has been determined in accordance with the rules promulgated under Section 13(d) of

ITEM 13.  CERTAIN  RELATIONSHIPS  AND  RELATED  TRANSACTIONS,  AND  DIRECTOR 

INDEPENDENCE 

We describe below transactions to which we were a party during our last two fiscal years or to which we 
currently propose to be a party in the future, and in which: 

 

 

the amounts involved exceeded or will exceed the lesser of $120,000 or one percent of the average 
of our total assets at year-end for the last two completed fiscal years; and  
any of our directors, executive officers or beneficial owners of more than 5% of any class of our 
voting securities, or any member of the immediate family of the foregoing persons, had or will have 
a direct or indirect material interest. 

Audit Committee Review 
Our  Audit  Committee  Charter  provides  for  the  review  by  the  Audit  Committee  of  any  related  party 
transactions,  other  than  transactions  involving  an  employment  relationship  with  the  Company,  which  are 
reviewed  by  the  Compensation  Committee.  Although  we  do  not  have  written  policies  for  the  review  of 
related party transactions, the Audit Committee reviews transactions between the Company and its directors, 
executive  officers,  holders  of  more  than  5%  of  any  class  of  the  Company’s  voting  securities,  and  their 
respective immediate family members. In reviewing a proposed transaction, the Audit Committee takes into 
account, among other factors it deems appropriate: 

(1)  the extent of the related person’s interest in the transaction; 
(2)  whether the transaction is on terms generally available to an unaffiliated third-party under the 

same or similar circumstances; 

107 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
(3)  the cost and benefit to the Company; 
(4)  the impact or potential impact on a director’s independence in the event the related party is a 
director, an immediate family member of a director or an entity in which a director is a partner, 
stockholder or executive officer; 

(5)  the availability of other sources for comparable products or services; 
(6)  the terms of the transaction; and 
(7)  the risks to the Company. 

In addition, as applicable, the Audit Committee considers Section 144 of the Delaware General Corporation 
Law (“DGCL”) and the Company’s Code of Ethics. 

The  provisions  of  Section  144  of  the  DGCL  apply  to  transactions  between  the  Company  and  any  of  its 
officers or directors, or any organization in which any such individual has a financial interest or serves as a 
director  or  officer  (individually,  a  “Section  144  Related  Party,”  and,  collectively,  “Section  144  Related 
Parties”). Section 144 provides that a transaction between a corporation and any Section 144 Related Party 
will not be void or voidable solely because such transaction involves the corporation and the Section 144 
Related Party, or solely because the Section 144 Related Party is present at or participates or votes in the 
meeting  of  the  board  or  committee  which  authorizes  the  transaction,  if  the  transaction  (a)  is  approved  in 
good  faith  after  full  disclosure  of  the  material  facts  of  the  transaction  by  a  majority  vote  of  (i)  the 
disinterested  directors,  or  (ii)  the  stockholders,  and  (b)  is  fair  as  to  the  corporation  as  of  the  time  it  is 
authorized, approved, or ratified by the board, a committee or the stockholders. 

Our  Code  of  Ethics,  which  applies  to  our  Board  and  all  our  employees,  including  the  executive  officers 
identified  under  the  heading  “Named  Executive  Officers”  and  our  senior  financial  officers,  provides  that 
such individuals must exhibit and promote honest and ethical conduct in connection with the performance of 
his  or  her  duties  for  and  on  behalf  of  the  Company,  including  the  ethical  handling  of  actual  or  apparent 
conflicts of interest involving such individual and the Company, by, among other considerations: 

  not  entering  into  a  transaction  that  would  result  in  a  conflict  of  interest  with  what  is  in  the  best 
interest of the Company and that is reasonably likely to result in material personal gain to any such 
individuals or their affiliates; 

  not having a personal financial interest in any of the Company’s suppliers, customers or competitors 
that  could  cause  divided  loyalty  as  a  result  of  having  the  ability  to  influence  the  Company’s 
decisions with that particular supplier or customer or actions to be taken by the Company that could 
materially benefit a competitor. 

Related  party  transactions  are  reviewed  by  the  Audit  Committee  prior  to  the  consummation  of  the 
transaction. With respect to a related party transaction arising between Audit Committee meetings, the CFO 
may  present  it  to  the  Audit  Committee  Chairperson,  who  will  review  and  may  approve  the  related  party 
transaction  subject  to  ratification  by  the  Audit  Committee  at  the  next  scheduled  meeting.  Our  Audit 
Committee shall approve only those transactions that, in light of known circumstances, are not inconsistent 
with the Company’s best interests. 

Related Party Transactions 
David Centofanti 
David  Centofanti  serves  as  our  Vice  President  of  Information  Systems.    For  such  position,  he  received 
annual  compensation of $191,000 and $187,000 for  2023  and  2022, respectively.  David  Centofanti is  the 
son of Dr. Louis F. Centofanti, our EVP of Strategic Initiatives and a Board member.   

Board Independence 
Our Common Stock is listed on the Nasdaq Capital Market. Rule 5605 of the Nasdaq Marketplace Rules 
requires  a  majority  of  a  listed  company's  board  of  directors  to  be  comprised  of  independent  directors.  In 
addition,  the  Nasdaq  Marketplace  Rules  require  that,  subject  to  specified  exceptions,  each  member  of  a 
listed company's audit, compensation and nominating and corporate governance committees be independent 
under  applicable  provisions  of  the  Securities  Exchange  Act  of  1934,  as  amended  (the  “Exchange  Act”). 

108 

 
 
 
 
 
 
 
 
Audit  committee  members  must  also  satisfy  independence  criteria  set  forth  in  Rule  10A-3  under  the 
Exchange Act, and compensation committee members must also satisfy the independence criteria set forth 
in Rule 10C-1 under the Exchange Act. Under Nasdaq Rule 5605(a)(2), a director will only qualify as an 
"independent director" if, in the opinion of our Board, that person does not have a relationship that would 
interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order 
to be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit 
committee  of  a  listed  company  may  not,  other  than  in  his  or  her  capacity  as  a  member  of  the  audit 
committee,  the  board  of  directors,  or  any  other  board  committee,  accept,  directly  or  indirectly,  any 
consulting,  advisory,  or  other  compensatory  fee  from  the  listed  company  or  any  of  its  subsidiaries  or 
otherwise be an affiliated person of the listed company or any of its subsidiaries. In order to be considered 
independent  for  purposes  of  Rule  10C-1,  the  board  must  consider,  for  each  member  of  a  compensation 
committee  of  a  listed  company,  all  factors  specifically  relevant  to  determining  whether  a  director  has  a 
relationship to such company which is material to that director's ability to be independent from management 
in connection with the duties of a compensation committee member, including, but not limited to: the source 
of compensation of the director, including any consulting advisory or other compensatory fee paid by such 
company to the director; and whether the director is affiliated with the company or any of its subsidiaries or 
affiliates. 

Our  Board  annually  reviews  the  composition  of  our  Board  of  Directors  and  its  committees  and  the 
independence  of  each  director.  Based  upon  information  requested  from  and  provided  by  each  director 
concerning  his/her  background,  employment  and affiliations,  including  family  relationships,  our  Board  of 
Directors  has  determined  that  Ms.  Kerry  C.  Duggan  and  each  of  Messrs.  Thomas  P.  Bostick,  Joseph  T. 
Grumski,  Joe  R.  Reeder,  Larry  M.  Shelton,  Zach  P.  Wamp  and  Mark  A.  Zwecker  is  an  "independent 
director" as defined under the Nasdaq Marketplace Rules. Our Board of Directors has also determined that 
each member of our Audit Committee, consisting of Mark A. Zwecker (Chairperson), Joseph T. Grumski, 
and Larry M. Shelton, and each member of our Compensation and Stock Option Committee, consisting of 
Joseph  T.  Grumski  (Chairperson),  Zach  P.  Wamp,  and  Mark  A.  Zwecker,  satisfy  the  independence 
standards  for  such  committees  established  by  the  Commission  and  the  Nasdaq  Marketplace  Rules,  as 
applicable.  In  making  such  determination,  our  Board  of  Directors  considered  the  relationships  that  each 
such  non-employee  director  has  with  our  Company  and  all  other  facts  and  circumstances  our  Board  of 
Directors deemed relevant in determining independence, including the beneficial ownership of our capital 
stock by each non-employee director. 

Our Board of Directors has determined that neither Dr. Louis Centofanti nor Mark J. Duff is deemed to be 
an “independent director” because of their employment as a senior executive of the Company.

audit services that are compatible with maintaining its independence, the Audit Committee has a policy that 
requires  the  Committee  to  review  and  approve  in  advance  all  services  to  be  provided  by  the  Company’s 
independent  accounting  firm  before  the  firm  is  engaged  to  provide  those  services.  The  Audit  Committee 
considers non-audit services and fees when assessing auditor independence, and determined that tax return 
preparation  and  other  tax  compliance  services  is  compatible  with  maintaining  our  accounting  firm's 
independence.  All  services  under  the  headings  Audit  Fees  and  Tax  Fees  were  approved  by  the  Audit 
Committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X of the Exchange Act.  The 
Audit Committee's pre-approval policy provides as follows: 

    The Audit Committee will review and pre-approve on an annual basis all audits, audit-related, 
tax and other services,  along  with  acceptable  cost levels,  to  be  performed by the  independent 
accounting  firm  and  any  member  of  the  independent  accounting  firm’s  alliance  network  of 
firms, and may revise the pre-approved services during the period based on later determinations. 
Pre-approved  services 
include:  audits,  quarterly  reviews,  regulatory  filing 
requirements, consultation on new accounting and disclosure standards, employee benefit plan 
audits, reviews and reporting on management's internal controls and specified tax matters. 
    Any  proposed  service  that  is  not  pre-approved  on  the  annual  basis  requires  a  specific  pre-

typically 

approval by the Audit Committee, including cost level approval. 

    The  Audit  Committee  may  delegate  pre-approval  authority  to  one  or  more  of  the  Audit 
Committee members. The delegated member must report to the Audit Committee, at the next 
Audit Committee meeting, any pre-approval decisions made.

Included  within  this  Annual  Report  is  a  list  briefly  describing  all  exhibits  listed  in  the  Company’s  Form  10-K.  We  will  furnish  any  exhibit  to  a  shareholder  upon 
receipt of a written request and payment of a specified reasonable fee, which fee shall be limited to the registrant’s reasonable expenses in furnishing such exhibit. 
Each request must set  forth  a  good-faith  representation  that,  as  of  the  record  date  for  the  solicitation  of  proxies,  the  person  making  the  request  was  a  beneficial 
owner of securities of the Company entitled to vote.

The  Company  defines  EBITDA  as  earnings  before  interest,  taxes,  depreciation  and  amortization.  Adjusted  EBITDA  is  defined  as  EBITDA  before  research  and 
development costs related to the Medical Isotope project, gain on extinguishment of debt, income from Employee Retention Credit (ERC) refund claim (net of costs 
incurred), and loss  on  deconsolidation  of  subsidiary  (where  applicable).  Both  EBITDA  and  adjusted  EBITDA  are  not  measures  of  performance  calculated  in 
accordance  with  accounting  standards  generally  accepted  in  the  United  States  of  America  (U.S.  GAAP),  and  should  not  be  considered  in  isolation  of,  or  as  a 
substitute  for,  earnings  as  an  indicator  of  operating  performance  or  cash  flows  from  operating  activities  as  a  measure  of  liquidity.  The  Company  believes  the 
presentation  of  EBITDA  and  adjusted  EBITDA  is  relevant  and  useful  by  enhancing  the  readers’  ability  to  understand  the  Company’s  operating  performance.  The 
Company’s management utilizes EBITDA and adjusted EBITDA as a means to measure performance. The Company’s meas urements of EBITDA and adjusted EBITDA 
may  not  be  comparable  to  similar  titled  measures  reported  by  other  companies.  The  table  below  reconciles  EBITDA  and  adjusted  EBITDA,  both  non-GAAP 
measures, to GAAP numbers for  income (loss) from continuing operations for the periods noted.
