Overview

PART I

We are a commercial-stage company that develops and sells high performance water solutions to the medical and commercial markets.

In medical markets, we sell water filtration products and waterborne pathogen detection products. Our medical water filters, mostly classified as ultrafilters,
are used primarily by hospitals for the prevention of infection from waterborne pathogens, such as legionella and pseudomonas, and in dialysis centers for
the removal of biological contaminants from water and bicarbonate concentrate. Because our ultrafilters capture contaminants as small as 0.005 microns in
size, they minimize exposure to a wide variety of bacteria, viruses, fungi, parasites, and endotoxins.

In commercial markets, we manufacture and sell water filters that improve the taste and odor of water and reduce biofilm, bacteria, and scale build-up in
downstream  equipment.  Marketed  under  both  the  Nephros  and  AETHER  brands,  our  products  are  marketed  primarily  to  the  food  service,  hospitality,
convenience store, and health care markets.

Our pathogen detection systems are portable, near real-time systems designed to provide actionable data for infection control teams, biomedical engineers
in dialysis clinics, and water quality teams in building management organizations.

We  also  have  a  subsidiary,  Specialty  Renal  Products,  Inc.  (“SRP”),  a  development-stage  medical  device  company,  focused  primarily  on  developing
hemodiafiltration  (“HDF”)  technology.  SRP  is  developing  a  second-generation  of  the  Nephros  OLpūr  H2H  Hemodiafiltration  System,  the  FDA  510(k)-
cleared medical device that enables nephrologists to provide HDF treatment to patients with end stage renal disease (“ESRD”).

We were founded in 1997 by healthcare professionals affiliated with Columbia University Medical Center/New York-Presbyterian Hospital to develop and
commercialize  an  alternative  method  to  hemodialysis.  We  have  extended  our  filtration  technologies  to  meet  the  demand  for  liquid  purification  in  other
areas, in particular, water purification.

COVID-19 Pandemic

Most  customers  and  prospects  –  including  healthcare,  hospitality,  and  food  and  beverage  –  have  re-opened  to  our  sales  activity  as  the  country  has
progressed through the COVID-19 pandemic. In addition, our filter emergency response business has normalized. We expect the pandemic to continue its
overall trend toward abatement in the coming months, but recent infection increases from new viral variants may interrupt that abatement for a period of
time, as has occurred with the Delta and Omicron variants.

During the pandemic, we maintained full operations, supporting our customers and strategic partners, with no significant interruptions in supply chain or
service capabilities.

We believe that, as the COVID-19 pandemic generally subsides, we may experience a net positive impact on demand for our products, due especially to
increased global awareness of infectious pathogens and the serious problems they cause. Specifically, we expect that:

● Purchase decisions for infection control filtration that had been deferred, both in new and existing customer organizations, may be re-prioritized.
● Demand for  our  pathogen  detection  products  may  increase  as  unoccupied  buildings,  including  office  buildings  and  hotels,  are  readied  for  re-
occupation.  Extended  periods  of  low,  or  no,  water  flow  through  building  piping  creates  opportunities  for  biofilm  propagation  –  a  problem  our
strategic partners are trained to eradicate.

● Demand for our commercial filtration products may increase as business returns to hotels, casinos, and restaurants.

Our Products

Water Filtration Products

We develop and sell water filtration products used in both medical and commercial applications. Our water filtration products employ multiple filtration
technologies, as described below.

In medical markets, our primary filtration mechanism is to pass liquids through the pores of polysulfone hollow fiber. Our filters’ pores are significantly
smaller  than  those  of  competing  products,  resulting  in  highly  effective  elimination  of  waterborne  pathogens,  including  legionella  bacteria  (the  cause  of
Legionnaires disease) and viruses, which are not eliminated by most other microbiological filters on the market. Additionally, the fiber structure and pore
density in our hollow fiber enables significantly higher flow rates than in other polysulfone hollow fiber.

Our primary sales strategy in medical markets is to sell through value-added resellers (“VARs”). Leveraging VARs has enabled us to expand rapidly our
access to target customers without significant sales staff expansion. In addition, while we are currently focused on medical markets, the VARs that support
these customers also support a wide variety of commercial and industrial customers. We believe that our VAR relationships will facilitate growth in filter
sales outside of the medical industry.

In  commercial  markets,  we  develop  and  sell  our  Nephros-  and  AETHER-branded  filters,  for  which  carbon-based  absorption  is  the  primary  filtration
mechanism.  Aether  products  allow  us  to  improve  water’s  odor  and  taste,  to  reduce  scale  and  heavy  metals,  and  to  reduce  other  water  contaminants  for
customers who are primarily in the food service, convenience store, and hospitality industries.

Our Aether  filter  offerings  have  the  potential  to  generate  accretive  revenue  growth  in  at  least  three  ways.  First,  we  expect  the  business  to  continue  its
organic  growth.  Second,  cross-selling  opportunities  are  generated  by  offering  taste/odor-focused  products  to  the  medical  markets,  as  well  as  pathogen-
focused  filtration  to  the  commercial  markets.  Finally,  as  part  of  the  more  substantial  Nephros  organization, Aether  may  be  able  to  compete  for  larger
filtration contracts than may have been available to it as a smaller, independent firm.

In commercial markets, our model combines both direct and indirect sales. Our sales staff have sold products directly to a number of convenience stores,
hotels, casinos, and restaurants. We are also pursuing large corporate contracts through partnerships.

Target Markets

Our ultrafiltration products currently target the following markets:

● Hospitals and Other Healthcare Facilities: Filtration of water for washing and drinking as an aid in infection control. The filters produce water that

is suitable for wound cleansing, cleaning of equipment used in medical procedures, and washing of surgeons’ hands.

● Dialysis Centers: Filtration of water or bicarbonate concentrate used in hemodialysis.
● Commercial  and  Industrial  Facilities:  Filtration  and  purification  of  water  for  consumption,  including  for  use  in  ice  machines  and  soft  drink

dispensers.

● Military and Outdoor Recreation: Individual water purification devices used by soldiers and backpackers to produce drinking water in the field, as

well as filters customized to remote water processing systems.

Hospitals and Other Healthcare Facilities. Nephros filters are a leading tool used to provide proactive protection to patients in high-risk areas (e.g., ice
machines, surgical rooms, NICUs) and reactive protection to patients in broader areas during periods of water pathogen outbreaks. Our products are used in
hundreds of medical facilities to aid in infection control, both proactively and reactively.

As  of  2019,  according  to  the  American  Hospital  Association,  there  are  approximately  6,100  hospitals  in  the  U.S.,  with  approximately  921,000  beds.  In
2019, over 36 million patients were admitted to these hospitals. The U.S. Centers for Disease Control and Prevention (“CDC”) estimates that healthcare
associated infections (“HAI”) occurr in approximately 1 out of every 31 hospital patients, which calculates to over 1 million patients in 2019. HAIs affect
patients  in  hospitals  or  other  healthcare  facilities  and  are  not  present  or  incubating  at  the  time  of  admission.  They  also  include  infections  acquired  by
patients in the hospital or facility, but appearing after discharge, and occupational infections among staff. Many HAIs are caused by waterborne bacteria
and viruses that can thrive in aging or complex plumbing systems often found in healthcare facilities.

In  June  2017,  the  Center  for  Clinical  Standards  and  Quality  at  the  Centers  for  Medicare  and  Medicaid  Services  (“CMS”)  announced  the  addition  of
requirements for facilities to develop policies and procedures that inhibit the growth and spread of legionella and other opportunistic pathogens in building
water  systems.  Going  forward,  CMS  surveyors  will  review  policies,  procedures,  and  reports  documenting  water  management  implementation  results  to
verify that facilities are compliant with these requirements. We believe that these CMS regulations may have a positive impact on the sale of our HAI-
inhibiting ultrafilters.

We currently have FDA 510(k) clearance on the following portfolio of medical device products for use in the hospital setting to aid in infection control:

● The  DSU-H  and  SSU-H  are  in-line,  0.005-micron  ultrafilters  that  provide  dual-  and  single-stage  protection,  respectively,  from  waterborne
pathogens. They are primarily used to filter potable water feeding ice machines, sinks, and medical equipment, such as endoscope washers and
surgical room humidifiers. The DSU-H has an up to 6-month product life in a typical hospital setting, while the SSU-H has an up to 3-month life.

● The S100  is  a  point-of-use,  0.01-micron  microfilter  that  provides  protection  from  waterborne  pathogens.  The  S100  is  primarily  used  to  filter

potable water feeding sinks and showers. The S100 has an up to 3-month product life when used in a hospital setting.

● The  HydraGuardTM  and  HydraGuardTM  -  Flush  are  0.005-micron  cartridge  ultrafilters  that  provide  single-stage  protection  from  waterborne
pathogens. The HydraGuard ultrafilters are primarily used to filter potable water feeding ice machines and medical equipment, such as endoscope
washers and surgical room humidifiers. The HydraGuard has an up to 6-month product life and the HydraGuard - Flush has an up to 12-month
product life when used in a hospital setting.

Our  complete  hospital  infection  control  product  line,  including  in-line,  point-of-use,  and  cartridge  filters,  can  be  viewed  on  our  website  at
http://www.nephros.com/infection-control/. We are not including the information on our website as a part of, nor incorporating it by reference into, this
Annual Report on Form 10-K.

Dialysis  Centers  -  Water/Bicarbonate.  In  the  dialysis  water  market,  Nephros  ultrafiltration  products  are  among  the  highest  performing  products  on  the
market. The DSU-D, SSU-D and the SSUmini have become the standard endotoxin filter in many portable reverse osmosis systems. The EndoPur®, our
large-format ultrafilter targeted at dialysis clinic water systems, provides the smallest pore size available. Following a long pilot project at a major dialysis
provider, we are now seeing growth in the use of this product. In addition, we aim to expand EndoPur’s usage into heat-disinfected water systems, which
will further open the market for this product.

To  perform  hemodialysis,  all  dialysis  clinics  have  dedicated  water  purification  systems  to  produce  water  and  bicarbonate  concentrate,  two  essential
ingredients for making dialysate, the liquid that removes waste material from the blood. According to the American Journal of Kidney Diseases, there are
approximately  6,500  dialysis  clinics  in  the  United  States  servicing  approximately  468,000  patients  annually.  We  estimate  that  there  are  over  100,000
hemodialysis machines in operation in the United States.

5

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Medicare is the main payer for dialysis treatment in the United States. To be eligible for Medicare reimbursement, dialysis centers must meet the minimum
standards for water and bicarbonate concentrate quality set by the Association for the Advancement of Medical Instrumentation (“AAMI”), the American
National Standards Institute (“ANSI”) and the International Standards Organization (“ISO”). We anticipate that the stricter standards approved by these
organizations in 2009 will be adopted by Medicare in the near future.

We currently have FDA 510(k) clearance on the following portfolio of medical device products for use in the dialysis setting to aid in bacteria, virus, and
endotoxin retention:

● The DSU-D, SSU-D and SSUmini are in-line, 0.005-micron ultrafilters that provide protection from bacteria, viruses, and endotoxins. All of these
products have an up to 12-month product life in the dialysis setting and are used to filter water following treatment with a reverse osmosis (“RO”)
system, and to filter bicarbonate concentrate. These ultrafilters are primarily used in the water lines and bicarbonate concentrate lines leading into
dialysis machines, and as a polish filter for portable RO machines.

● The EndoPur is a 0.005-micron cartridge ultrafilter that provides single-stage protection from bacteria, viruses, and endotoxins. The EndoPur has
an up to 12-month product life in the dialysis setting and is used to filter water following treatment with an RO system. More specifically, the
EndoPur is used primarily to filter water in large RO systems designed to provide ultrapure water to an entire dialysis clinic. The EndoPur is a
cartridge-based, “plug and play” market entry that requires no plumbing at installation or replacement. The EndoPur is available in 10”, 20”, and
30” configurations.

Commercial  and  Industrial  Facilities.  Our  commercial  NanoGuard®  product  line  accomplishes  ultrafiltration  via  small  pore  size  (0.005  micron)
technology, filtering bacteria and viruses from water. In addition, the AETHER brand expanded our product line to include water filtration and purification
technologies that are primarily focused on improving odor and taste and on reducing scale and heavy metals from filtered water.

We purchased the AETHER brand to expedite our access to commercial markets and to expand our filtration expertise and capabilities. Our commercial
market  focus  is  on  the  hotel,  restaurant,  and  convenience  store  markets.  In  the  first-year  post-acquisition,  we  upgraded  Aether  facilities  to  increase
production and logistics capacity, integrated Aether products into the Nephros infection control product portfolio, and initiated sales efforts with several
large commercial customers. We have recently added to our commercial sales team and, going forward, expect to close on one or more large contracts that
may result in step-change increases in commercial market revenue.

Over time, we believe that the same water safety management programs currently underway at medical facilities may migrate to commercial markets. As
the epidemiology of waterborne pathogens expands, links to contamination sources will become more efficient and the data more readily available. In cases
where those sources are linked to restaurants, hotels, office buildings and residential complexes, the corporate owners of those facilities will likely face
increasing liability exposure. We expect that building owners will come to understand ASHRAE-188, which outlines risk factors for buildings and their
occupants, and provides water safety management guidelines. We believe, in time, most commercial buildings will need to follow the basic requirements of
ASHRAE-188: create a water management plan, perform routine testing, and establish a plan to treat the building in the event of a positive test.

As  demand  for  water  testing  and  microbiological  filtration  grows,  we  will  be  ready  to  deploy  our  expertise  and  solutions  based  on  years  of  experience
servicing the medical market. We believe that we have an opportunity to offer unique expertise and products to the commercial market, and that our future
revenue from the commercial market could even surpass our infection control revenue.

We currently market the following portfolio of proprietary products for use in the commercial, industrial, and food service settings:

● The NanoGuard set of products are in-line, 0.005-micron ultrafilter that provides dual-stage retention of any organic or inorganic particle larger
than  15,000  Daltons.  NanoGuard  products  are  designed  to  fit  a  variety  of  existing  plumbing  configurations,  including  10”  and  20”  standard
housings, and AETHER and Everpure® manifolds. Included in the NanoGuard product line are both conventional and flushable filters.

● The AETHER line of commercial filters, which are also sold under the Nephros brand, provide a variety of technology solutions that improve
water quality in food service, convenience store, hospitality, and industrial applications. AETHER filters improve water taste and odor, and reduce
sediment, dirt, rust particles and other solids, chlorine and heavy minerals, lime scale build-up, and both particulate lead and soluble lead.

6

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
AETHER  products  combine  effectively  with  NanoGuard  ultrafiltration  technologies  to  offer  full-featured  solutions  to  the  commercial  water  market,
including to existing users of Everpure filter manifolds.

Military  and  Outdoor  Recreation.  We  developed  our  individual  water  treatment  device  (“IWTD”)  in  both  in-line  and  point-of-use  configurations.  Our
IWTD  allows  a  soldier  in  the  field  to  derive  drinking  water  from  any  freshwater  source.  This  enables  the  soldier  to  remain  hydrated,  to  help  maintain
mission  effectiveness  and  unit  readiness,  and  to  extend  mission  reach.  Our  IWTD  has  been  validated  by  the  military  to  meet  the  NSF  Protocol  P248
standard. It has also been approved by the U.S. Army Public Health Command and the U.S. Army Test and Evaluation Command for deployment.

In May 2015, we entered into a Sublicense Agreement (the “Sublicense Agreement”) with CamelBak Products, LLC (“CamelBak”). Under this Sublicense
Agreement, we granted CamelBak an exclusive, non-transferable, worldwide (with the exception of Italy) sublicense and license, in each case solely to
market, sell, distribute, import and export the IWTD. In exchange for the rights granted to CamelBak, CamelBak agreed, through December 31, 2022, to
pay us a percentage of the gross profit on any sales made to a branch of the U.S. military, subject to certain exceptions, and to pay us a fixed per-unit fee for
any other sales made. CamelBak was also required to meet or exceed certain minimum annual fees payable to us, and, if such fees are not met or exceeded,
we  were  able  to  convert  the  exclusive  sublicense  to  a  non-exclusive  sublicense  with  respect  to  non-U.S.  military  sales.  In  the  first  quarter  of  2019,  the
Sublicense Agreement was amended to eliminate the minimum fee obligations starting May 6, 2018, and, as such, CamelBak has no further minimum fee
obligations. Related to this Sublicense Agreement, approximately $5,000 of revenue was recognized during the year ended December 31, 2021. There was
no royalty revenue recognized during the year ended December 31, 2021.

Pathogen Detection Systems

Pathogen  Detection  in  Infection  Control.  We  recently  expanded  our  portfolio  of  solutions  with  the  introduction  of  our  PluraPath™  pathogen  detection
system, which we believe represents a significant growth opportunity for Nephros.

We developed the PluraPath pathogen detection system to provide real-time data to infection control teams executing their water management plans. We
integrated  our  ultrafilter  technology  with  emerging,  quantitative  polymerase  chain  reaction  (qPCR)  technology  and  real-time  analytics.  We  chose  a
portable, open-source qPCR platform that allows us to parallel-processes up to 15 different bacteria and virus assays. We worked with industry experts to
select and develop DNA- and RNA-based assays that could meet our goals of providing quantitative precision within one hour. We also developed a mobile
application to extract and process the data real-time. Furthermore, we designed the system so that anyone can perform qPCR testing, not just someone with
training in microbiological laboratory techniques.

With the PluraPath system, it will be possible to map and track the changes to levels of multiple bacterial and viral pathogens in a building’s water system
on a real-time basis, at cost levels equivalent to assays that currently take 24-72 hours or more and typically provide data on only a single pathogen. Using
PluraPath, we expect that infection control teams will be able to quickly assess approximate levels of a broad array of pathogens in their water systems, and
optimally focus their secondary disinfection efforts and point-of-use filtration; services and products offered by our strategic partners.

The  PluraPath  system  does  not  replace  culture-based  assays,  which  are  the  current  regulatory  requirements  for  confirmation  in  testing  for  waterborne
pathogens.  Rather,  we  believe  PluraPath  will  become  a  valuable  tool  in  the  arsenal  of  defense,  permitting  faster  decision  making  about  a  larger  target
population of pathogens. Our objective is to provide our customers and strategic partners with a user-friendly system that delivers dependable, actionable

Pathogen Detection in Dialysis Facilities. We have also been investigating pathogen detection efforts in the dialysis space. The LAL (limulus amebocyte
lysate) test is a dialysis industry standard assay that identifies the presence of potential endotoxins, agnostic to the source species. The source of endotoxins
are gram-negative bacteria. LAL testing routinely takes 48-72 hours to provide results from the time of shipping the sample to a central laboratory. When
dialysis  clinics  have  urgent  contamination  or  severely  elevated  endotoxin  issues,  they  may  have  to  shut  down  for  extended  periods  of  time  creating
enormous logistical issues for patients and increasing the cost of care.

To provide a real-time solution for this testing paradigm, we announced the DialyPath™ pathogen detection and endotoxin estimation system in October
2020. The DialyPath system mirrors our PluraPath but includes a gram-negative DNA marker test and test for six different gram-negative bacteria. The
DialyPath  system  is  designed  to  provide  data  on  two  test  samples  in  one  run  in  less  than  one  hour.  The  system  will  provide  an  estimate  of  the  overall
endotoxin in the sample, as well as estimated levels of six specific endotoxin-generating bacteria known to be frequent invaders of dialysis clinic water
systems.

Facility-Wide Pathogen Detection. Bacterial contaminants in water systems can originate from thousands of different bacterial families. The technology
now exists to map the water system biome in real-time, on-site, using an enhanced form of the portable PluraPath system and a bioinformatics database.
The SequaPath system provides the capability to screen water for over 20,000 different bacterial genera (families), including genera of the 40+ pathogenic
bacteria listed by the Centers for Disease Control & Prevention (CDC) in their “Opportunistic Pathogens of Premise Plumbing.” The system incorporates
our  proprietary  filtration  technology  and  a  DNA  sequencing  step  that  makes  it  possible  to  screen  rapidly  for  genera  of  waterborne  pathogens.  Like
PluraPath, the SequaPath platform is portable, allowing for same-day on-site analysis.

The SequaPath technology was used in 2020 to perform an academic study that found far more bacteria in buildings unoccupied during the COVID-19
pandemic than in occupied buildings. The potential for building biome mapping is enormous. We are developing the technology, processes, and procedures
to perform as many as 96 tests in a single run. SequaPath is currently available as a service offering.

While this service could be of value to the management of any water system in any building in any part of the world, we will first focus on the hospital
customers  of  our  strategic  partners.  Once  proven  in  the  hospital  space,  we  believe  that  SequaPath  has  the  potential  to  shift  the  building  water  testing
paradigm across multiple markets and geographies.

Our Pathogen Detection Systems laboratories facility in Reno, Nevada, has matured into a first-class, environmental test development and manufacturing
organization.  The  lab  was  recently  enrolled  in  the  CDC’s  ELITE  Program,  which  recognizes  approximately  150  US  laboratories  capable  of  advanced
isolation techniques with respect to Legionella identification. Our focus extends well beyond Legionella. Indeed, we believe our laboratories now offer the
most extensive list of CDC-noted, opportunistic waterborne pathogens in a single test on the market today.

On July 9, 2021, we acquired 100% of GenArraytion, Inc. (“GenArraytion”). This acquisition gave us access to GenArraytion’s many proprietary assays,
multiplexing  technology,  and  selection  methods  for  detecting  waterborne  pathogens  and  other  microorganisms  using  Polymerase  Chain  Reaction
technology. GenArraytion’s assets will be integrated into our Pathogen Detection Systems segment.

Additional  Pathogen  Detection  Markets.  Due  primarily  to  the  intellectual  property  acquired  in  the  GenArraytion  acquisition,  including  proprietary
techniques  of  rapid  assay  development,  we  are  exploring  additional  pathogen  detection  market  opportunities,  including  additional  waterborne  pathogen
detection markets as well as non-waterborne areas, such as mosquito- and tick-borne illness and women’s health panels.

Specialty Renal Products: HDF System

Introduction to HDF

The current standard of care in the United States for patients with chronic renal failure is hemodialysis (“HD”), a process in which toxins are cleared via
diffusion. Patients typically receive HD treatments at least 3 times weekly for 3-4 hours per treatment. HD is most effective in removing smaller, easily
diffusible toxins. For patients with acute renal failure, the current standard of care in the United States is hemofiltration (“HF”), a process where toxins are
cleared  via  convection.  HF  offers  a  much  better  removal  of  larger  sized  toxins  when  compared  to  HD;  however,  HF  treatment  is  more  challenging  for
patients, as it is performed daily, and typically takes 12-24 hours per treatment.

Hemodiafiltration (“HDF”) is an alternative dialysis modality that combines the benefits of HD and HF into a single therapy by clearing toxins using both
diffusion and convection. Though not widely used in the United States, HDF is prevalent in Europe and is performed for a growing number of patients.
Clinical experience and literature show the following clinical and patient benefits of HDF:

● Enhanced clearance of middle and large molecular weight toxins
● Improved survival - up to a 35% reduction in mortality risk
● Reduction in the occurrence of dialysis-related amyloidosis
● Reduction in inflammation
● Reduction in medication such as EPO and phosphate binders
● Improved patient quality of life
● Reduction in number of hospitalizations and overall length of stay

However, like HD, HDF can be resource-intensive and can require a significant amount of time to deliver one course of treatment.

Nephros HDF Background

Over the course of our history, we originally developed a medical device that enabled a standard HD machine to perform HDF. We refer to our approach as
an on-line mid-dilution hemodiafiltration (“mid-dilution HDF”) system. Our original solution included an OLpūr H2H Hemodiafiltration Module (“H2H
Module”), an OLpūr MD 220 Hemodiafilter (“HDF Filter”) and an H2H Substitution Filter (“Dialysate Filter”).

Our  H2H  Module  attaches  to  a  standard  HD  machine  to  perform  on-line  HDF  therapy.  The  HD  machine  controls  and  monitors  the  basic  treatment
functions, as it would normally when providing HD therapy. The H2H Module is a free-standing, movable device that is placed next to either side of an HD
machine. The H2H Module connects to the clinic’s water supply, drain, and electricity.

The H2H Module utilizes the HDF Filter and is very similar to a typical hollow fiber dialyzer assembled with a single hollow fiber bundle made with a
high-flux  (or  high-permeability)  membrane.  The  fiber  bundle  is  separated  into  two  discrete,  but  serially  connected,  blood  paths.  Dialysate  flows  in  one
direction that is counter-current to blood flow in Stage 1 and co-current to blood flow in Stage 2.

In addition to the HDF Filter, the H2H Module also utilizes a Dialysate Filter during patient treatment. The Dialysate Filter is a hollow fiber, ultrafilter
device that consists of two sequential (redundant) ultrafiltration stages in a single housing. During on-line HDF with the H2H Module, fresh dialysate is
redirected by the H2H Module’s hydraulic (substitution) pump and passed through this dual-stage ultrafilter before being infused as substitution fluid into
the extracorporeal circuit. Providing ultrapure dialysate is crucial for the success of on-line HDF treatment.

Our original HDF system conformed with current ANSI/AAMI/ISO standards and was cleared by the U.S. Food and Drug Administration (“FDA”) for the
treatment of patients with chronic renal failure in 2012. To date, our HDF System is the only HDF system cleared by the FDA.

Over  the  last  four  years,  DaVita  Healthcare  Partners,  the  Renal  Research  Institute  (a  research  division  of  Fresenius  Medical  Care),  and  Vanderbilt
University  conducted  post-market  evaluations  of  our  hemodiafiltration  system  in  their  clinics.  We  gathered  direct  feedback  from  these  evaluations  to
develop  a  better  understanding  of  how  our  system  best  fits  into  the  current  clinical  and  economic  ESRD  treatment  paradigm. The  ultimate  goal  of  the
evaluations was to better understand the potential for HDF in the U.S. clinical setting in order to (a) improve the quality of life for the patient, (b) reduce
overall  expenditure  compared  to  other  dialysis  modalities,  (c)  minimize  the  impact  on  nurse  workflow  at  the  clinic,  and  (d)  demonstrate  the
pharmacoeconomic benefit of the HDF technology to the U.S. healthcare system, as has been done in Europe with other HDF systems. The last evaluation
was concluded at Vanderbilt in the first quarter of 2018.

Specialty Renal Products, Inc.

Over the past two years, we have dramatically simplified and redesigned our HDF device. Our updates have made the system significantly easier to use. By
shifting from a reusable substitution ultrafilter to a disposable substitution ultrafilter, we were able to simplify the set-up process and substantially reduce
the time required between patient treatments – two of the key complaints from users of our first-generation system. We used real-time user feedback to aid
in  the  fine-tuning  of  our  changes  to  the  system  that  impacted  usability.  We  believe  our  second-generation  HDF  system  will  meet  the  needs  of  both
clinicians and patients.

In 2018, we spun-off the development of the HDF device into SRP. We raised $3 million of outside capital directly into SRP to fund the second-generation
development described above. Nephros maintains a 62.5% ownership stake in SRP.

We submitted the second-generation HDF system for FDA clearance in June 2021. In October 2021, after an elongated review process, the FDA accepted
SRP’s HDF Assist Device into its “substantive review” phase for 510(k) clearance. In late December 2021, FDA requested additional information from
SRP about its submission. Specifically, the FDA requested additional support for the shelf-life and stability of SRP’s disposables; changes to its labels,
documentation, and user screens; additional electrical testing; additional user testing; and additional HD machine-specific system performance testing. We
expect to complete the work to address the FDA’s list in March or April of this year.

Once  the  HDF  system  is  cleared  by  the  FDA,  we  intend  to  launch  it  at  2-3  clinics  having  previous  experience  with  our  device.  Thereafter,  we  plan  to
expand our efforts, on a measured basis, to clinics that wish to provide HDF therapy to their patients. We believe this measured launch approach is more
likely to be successful than a broader push into the market. Nephrologists in the United States are not trained on HDF therapy; however, we believe many
nephrologists are interested in exploring the option. We also believe that early adopters will want to perform studies to better understand the technology.
We intend to support these investigator-initiated studies.

In anticipation of clearance, SRP has begun to manufacture supplies for its commercial launch, identify and hire key commercial launch staff, and select its
initial commercial clinics. Prior to FDA approval, supplies manufactured in preparation for commercial launch are expensed. We anticipate that SRP will
obtain 510(k) clearance in the first half of 2022 and will be in position to launch in the second half of the year.

While a number of studies have been performed in Europe, the body of evidence for optimal use of HDF needs to be built in the U.S. treatment setting.
According to European data from Fresenius, over 15% of dialysis treatments are HDF. That could translate to over 10 million individual treatments if HDF
achieved that level of penetration in the United States. We do not believe that the United States will instantaneously mirror Europe. However, we do believe
that HDF therapy has a place in the treatment landscape for patients with ESRD in the United States, and we look forward to enabling this pathway.

Manufacturing and Suppliers

We do not, and do not intend to in the near future, manufacture any of our medical device filtration products. We do manufacture some of our commercial
filtration products in our Aether facility in Las Vegas, Nevada. In addition, we plan to manufacture some pathogen detection products in our Reno, Nevada
facility.

Regarding the OLpūr MD190 and MD220, on June 27, 2011, we entered into a License Agreement (the “License Agreement”), effective July 1, 2011, as
amended  by  the  first  amendment  dated  February  19,  2014,  with  Bellco  S.r.l.  (“Bellco”),  an  Italy-based  supplier  of  hemodialysis  and  intensive  care
products, for the manufacturing, marketing and sale of our patented mid-dilution dialysis filters. Under the License Agreement, as amended, we granted
Bellco a license to manufacture, market and sell the covered products under its own name, label, and CE mark in certain countries on an exclusive basis,
and to do the same on a non-exclusive basis in certain other countries. The License Agreement expired on December 31, 2021.

On April 23, 2012, we entered into a License and Supply Agreement (the “License and Supply Agreement”) with Medica S.p.A. (“Medica”), an Italy-based
medical  product  manufacturing  company,  for  the  marketing  and  sale  of  certain  filtration  products  based  upon  Medica’s  proprietary  Medisulfone

Medica expires on December 31, 2025, unless earlier terminated by either party in accordance with the terms of the License and Supply Agreement.

In exchange for the rights granted, we agreed to make minimum annual aggregate purchases from Medica throughout the term of the License and Supply
Agreement. As part of the License and Supply Agreement, we granted to Medica 300,000 options to purchase our common stock, which vested over the
first three years of the agreement. We currently have an understanding with Medica whereby we have agreed to pay interest to Medica at a 12% annual rate
calculated on the principal amount of any outstanding invoices that are not paid pursuant to the original payment terms.

Sales and Marketing

Under the Bellco License Agreement, as discussed above, we granted Bellco a license to manufacture, market and sell the covered products under its own
name, label, and CE mark in the territory, as defined in the License Agreement. In addition, if requested by us, Bellco will be required to sell the covered
products to our distributors in the stated territory.

Our New Jersey headquarters oversees global sales and marketing activity of our ultrafilter products. We work with multiple distributors for our ultrafilter
products  in  the  hospital  and  dialysis  water  markets.  For  the  food  service  and  hospitality  markets,  our  Aether  division  leads  global  sales  and  marketing
activity. For other prospective markets for our ultrafilter products, we are pursuing alliance opportunities for joint product development and/or distribution.
Our ultrafilter manufacturer in Europe shares certain intellectual property rights with us for one of our dual stage ultrafilter designs.

Research and Development

Our research and development efforts continue on several fronts directly related to our current product lines. For the ultrafiltration systems business, we are
continually  working  with  existing  and  potential  distributors  of  ultrafilter  products  to  develop  solutions  to  meet  customer  needs.  Our  pathogen  detection
systems  organization  is  driving  the  development  of  PluraPath  and  other  related  systems  planned  for  the  future.  Our  SRP  subsidiary  is  driving  the
development of our second-generation HDF system.

Competition

With respect to the water filtration market, we compete with companies that are well-entrenched in the water filtration domain. These companies include
Pall Corporation (now wholly owned by Danaher Corporation), which manufactures point-of-use microfiltration products, as well as 3M and Pentair, who
manufacture the Cuno® and Everpure® brands of water filtration and purification products respectively. Our methods of competition in the water filtration
domain include:

● developing and marketing products that are designed to meet critical and specific customer needs more effectively than competitive devices;
● offering unique attributes that illustrate our product reliability, “user-friendliness,” and performance capabilities;
● selling products to specific customer groups where our unique product attributes are mission-critical; and
● pursuing alliance and/or acquisition opportunities for joint product development and distribution.

The  PluraPath  pathogen  detection  system  will  compete  in  the  $8  billion  global  water  testing  market.  Portable,  real-time  water  testing,  however,  is  a
relatively new market, with few competitors, including Spartan Bioscience.

The dialyzer and renal replacement therapy market is subject to intense competition. Accordingly, our future success will depend on our ability to meet the
clinical goals of nephrologists, improve patient outcomes, and remain cost-effective for payers.

We  also  compete  with  other  suppliers  of  ESRD  therapies,  supplies  and  services.  These  suppliers  include  Fresenius  Medical  Care  AG  and  Baxter
International, Inc., currently two of the primary machine manufacturers in hemodialysis. Fresenius Medical Care AG and Baxter International, Inc. also
manufacture HDF machines that are not currently approved in the United States.

The  markets  in  which  we  sell  our  dialysis  products  are  highly  competitive.  Our  competitors  in  the  sale  of  hemodialysis  products  include  Baxter
International Inc., Fresenius Medical Care AG, Asahi Kasei Medical Co. Ltd., B. Braun Melsungen AG, Nipro Medical Corporation Ltd., Nikkiso Co.,
Ltd., Terumo Medical Corporation and Toray Medical Co., Ltd.

Other competitive considerations include pharmacological and technological advances in preventing the progression of ESRD in high-risk patients, such as
those with diabetes and hypertension, technological developments by others in the area of dialysis, the development of new medications designed to reduce
the incidence of kidney transplant rejection, and progress in using kidneys harvested from genetically engineered animals as a source of transplants.

We  are  not  aware  of  any  other  companies  using  technology  similar  to  ours  in  the  treatment  of  ESRD.  Our  competition  would  increase,  however,  if
companies that currently sell ESRD products, or new companies that enter the market, develop technology that is more efficient than ours. We believe that
in order to become competitive in this market, we will need to develop and maintain competitive products and take and hold sufficient market share from
our competitors. Therefore, we expect our methods of competing in the ESRD marketplace to include:

● continuing our efforts to develop, manufacture, and sell products that, when compared to competitive products, perform more efficiently, and are

available at prices that are acceptable to the market;

● displaying our products and providing associated literature at major industry trade shows in the United States;
● initiating  discussions  with  dialysis  clinic  medical  directors,  as  well  as  representatives  of  dialysis  clinical  chains,  to  develop  interest  in  our

products;

● pursuing alliance opportunities in certain territories for distribution of our products and possible alternative manufacturing facilities; and
● entering into license agreements similar to our License Agreement with Bellco to expand market share.

Intellectual Property

Patents

We  protect  our  technology  and  products  through  patents  and  patent  applications.  In  addition  to  the  United  States,  we  also  apply  for  patents  in  other
jurisdictions,  such  as  the  European  Patent  Office,  Canada,  and  Japan,  to  the  extent  we  deem  appropriate.  We  have  built  a  portfolio  of  patents  and
applications covering our products, including their hardware design and methods of hemodiafiltration.

We  believe  that  our  patent  strategy  will  provide  a  competitive  advantage  in  our  target  markets,  but  our  patents  may  not  be  broad  enough  to  cover  our
competitors’ products and may be subject to invalidation claims. Our U.S. patents for the “Method and Apparatus for Efficient Hemodiafiltration” and for
the  “Dual-Stage  Filtration  Cartridge”  have  claims  that  cover  the  OLpūr  MDHDF  filter  series  and  the  method  of  hemodiafiltration  employed  in  the
operation of the products. Technological developments in ESRD therapy could reduce the value of our intellectual property. Any such reduction could be
rapid and unanticipated. We have issued patents on our water filtration products and applications in process to cover various applications in residential,
commercial, and remote environments.

As of December 31, 2021, we had five U.S. patents, one Chinese patent, one French patent, one German patent, one Italian patent, one United Kingdom
patent, and one Canadian patent. In addition, we had two pending patent applications in the United States. Our pending patent applications relate to a range
of filter technologies, including liquid purification filter systems and portable systems for detecting waterborne pathogens by rapid filtration, concentration,
and detection of the waterborne pathogens.

Trademarks

As  of  December  31,  2021,  in  the  United  States,  we  secured  registrations  of  the  trademarks  HYDRAGUARD,  NANOGUARD,  ENDOPUR,  FILPATH,
PLURAPATH, DIALYPATH MULTIFLEX, MULTIFLEX BIOASSAY, GenArraytion and SEQUAPATH. In Canada, we filed trademark applications for
PLURAPATH and SEQUAPATH. In Europe and the UK, we secured registrations for the trademark MULTIFLEX.

Governmental Regulation

The research and development, manufacturing, promotion, marketing and distribution of our ESRD therapy products in the United States, Europe and other
regions of the world are subject to regulation by numerous governmental authorities, including the FDA, the European Union and analogous agencies.

13

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
United States

The FDA regulates the manufacture and distribution of medical devices in the United States pursuant to the Food, Drug, and Cosmetics (FDC) Act. All of
our ESRD therapy products are regulated in the United States as medical devices by the FDA under the FDC Act. Under the FDC Act, medical devices are
classified in one of three classes, namely Class I, II or III, on the basis of the controls deemed necessary by the FDA to reasonably ensure their safety and
effectiveness.

● Class I  devices  are  medical  devices  for  which  general  controls  are  deemed  sufficient  to  ensure  their  safety  and  effectiveness.  General  controls
include  provisions  related  to  (1)  labeling,  (2)  producer  registration,  (3)  defect  notification,  (4)  records  and  reports  and  (5)  quality  service
requirements (“QSR”).

● Class II devices are medical devices for which the general controls for the Class I devices are deemed not sufficient to ensure their safety and
effectiveness and require special controls in addition to the general controls. Special controls include provisions related to (1) performance and
design standards, (2) post-market surveillance, (3) patient registries and (4) the use of FDA guidelines.

● Class III devices are the most regulated medical devices and are generally limited to devices that support or sustain human life or are of substantial
importance in preventing impairment of human health or present a potential, unreasonable risk of illness or injury. Pre-market approval by the
FDA is the required process of scientific review to ensure the safety and effectiveness of Class III devices.

Before  a  new  medical  device  can  be  introduced  to  the  market,  Section  510(k),  and  Section  515  of  the  FDC  Act  require  a  manufacturer  who  intends  to
market a medical device to submit a premarket notification (Section 510(k)) or a request for premarket approval (Section 515), to the FDA.

A  510(k)  clearance  will  be  granted  if  the  submitted  information  establishes  that  the  proposed  device  is  “substantially  equivalent”  to  a  legally  marketed
Class I or Class II medical device or to a Class III medical device for which the FDA has not called for premarket approval under Section 515. The 510(k)
clearance process is generally faster and simpler than the premarket approval process.

Premarket approval (PMA) is the FDA’s process of scientific and regulatory review to evaluate the safety and effectiveness of Class III medical devices.
Class III devices are those that support or sustain human life, are of substantial importance in preventing impairment of human health, or which present a
potential, unreasonable risk of illness or injury, or are new and present unknown safety or effectiveness issues or risks. PMA is the most stringent type of
device marketing application required by the FDA. To gain approval, the manufacturer must present adequate scientific evidence to assure that the device is
safe and effective for its intended use(s).

For any devices cleared through the 510(k) clearance process, modifications or enhancements that could significantly affect the safety or effectiveness of
the device or that constitute a major change to the intended use of the device will require a new 510(k) clearance submission. Accordingly, if we do obtain
Section  510(k)  clearance  for  any  of  our  ESRD  therapy  and/or  filtration  products,  we  will  need  to  submit  another  Section  510(k)  notification  if  we
significantly affect that product’s safety or effectiveness through subsequent modifications or enhancements.

All of our products have been cleared by the FDA as Class II devices, such as:

● DSU Dual Stage UltraFilter: In June 2009, we received FDA 510(k) clearance of the DSU to be used to filter biological contaminants from water

and bicarbonate concentrate used in hemodialysis procedures.

● SSU-D/DSU-D Dual Stage UltraFilter: In July 2011, we received FDA 510(k) clearance of the SSU/DSU to be used to filter water or bicarbonate

concentrate used in hemodialysis procedures.

● OLpūr H2H Module and OLpūr MD 220 Hemodiafilter: In April 2012, we received FDA 510(k) clearance of the OLpūr H2H Module and OLpūr
MD  220  Hemodiafilter  for  use  with  a  UF  controlled  hemodialysis  machine  that  provides  ultrapure  dialysate  in  accordance  with  current
ANSI/AAMI/ISO standards, for the treatment of patients with chronic renal failure in the United States.

● DSU-H/SSU-H:  In  October  2014,  we  received  FDA  510(k)  clearance  of  the  DSU-H  and  SSU-H  ultrafilters  to  be  used  to  filter  EPA  quality
drinking water. The filters retain bacteria, viruses, and endotoxin. By providing ultrapure water for patient washing and drinking, the filters aid in
infection control.

● S100 Point of Use Filter: In April 2016, we received FDA 510(k) clearance of the S100 point-of-use filter to be used to filter EPA quality drinking

water. The filters retain bacteria. By retaining bacteria in water for washing and drinking, the filter may aid in infection control.

● HydraGuard: In December 2016, we received FDA 510(k) clearance of the HydraGuard 10” ultrafilter intended to be used to filter EPA quality
drinking water. The filter retains bacteria, viruses and endotoxin. By providing ultrapure water for patient washing and drinking, the filter aids in
infection control.

● EndoPur: In March 2017, we received FDA 510(k) clearance of the EndoPur ultrafilter intended to be used to filter water used in hemodialysis
devices. It assists in providing hemodialysis quality water. The device is not a complete water treatment system but serves to remove biological
contaminants. Therefore, it must be used in conjunction with other water treatment equipment (Reverse Osmosis, Deionization, etc.).

The FDC Act requires that medical devices be manufactured in accordance with the FDA’s current QSR regulations which require, among other things,
that:

● the design and manufacturing processes be regulated and controlled by the use of written procedures;
● the ability to produce medical devices which meet the manufacturer’s specifications be validated by extensive and detailed testing of every aspect

of the process;

● any deficiencies in the manufacturing process or in the products produced be investigated;
● detailed records be kept, and a corrective and preventative action plan be in place; and
● manufacturing facilities be subject to FDA inspection on a periodic basis to monitor compliance with QSR regulations.

In addition to the requirements described above, the FDC Act requires that:

● all medical device manufacturers and distributors register with the FDA annually and provide the FDA with a list of those medical devices which

they distribute commercially;

● information be provided to the FDA on death or serious injuries alleged to have been associated with the use of the products, as well as product

malfunctions that would likely cause or contribute to death or serious injury if the malfunction were to recur; and

● certain medical devices not cleared with the FDA for marketing in the United States meet specific requirements before they are exported.

We and our contract manufacturers are required to manufacture our products in compliance with current Good Manufacturing Practice (GMP) requirements
set forth in the QSR. The QSR requires a quality system for the design, manufacture, packaging, labeling, storage, installation, and servicing of marketed
devices, and it includes extensive requirements with respect to quality management and organization, device design, buildings, equipment, purchase and
handling  of  components  or  services,  production  and  process  controls,  packaging  and  labeling  controls,  device  evaluation,  distribution,  installation,
complaint  handling,  servicing,  and  record  keeping.  The  FDA  evaluates  compliance  with  the  QSR  through  periodic  unannounced  inspections  that  may
include the manufacturing facilities of our subcontractors. If the FDA believes that we or any of our contract manufacturers, or regulated suppliers, are not
in compliance with these requirements, there may be a material adverse effect on our manufacturing operations, effecting our ability to sell.

European Union

The  European  Union  began  to  harmonize  national  regulations  comprehensively  for  the  control  of  medical  devices  in  member  nations  in  1993,  when  it
adopted  its  Medical  Devices  Directive  93/42/EEC.  The  European  Union  directive  applies  to  both  the  manufacturer’s  quality  assurance  system  and  the
product’s technical design and discusses the various ways to obtain approval of a device (dependent on device classification), how to properly CE mark a
device, and how to place a device on the market.

In 2017, the European Union (EU) adopted the EU Medical Device Regulation (Council Regulations 2017/745) which imposes stricter requirements for the
marketing  and  sale  of  medical  devices,  including  new  quality  system  and  post-market  surveillance  requirements.  The  regulation  has  a  three-year
implementation period to May 2020 and will replace the existing directives on medical devices in the EU. After May 2020, medical devices marketed in the
EU  require  certification  according  to  these  new  requirements,  except  that  devices  with  valid  CE  certificates,  issued  pursuant  to  the  Medical  Device
Directive  before  May  2020,  may  be  placed  on  the  market  until  2024.  Complying  with  this  new  regulation  will  require  us  to  incur  significant  costs  and
failure to meet the requirements of the regulation could adversely impact our business in the European Union and other countries that utilize or rely on
European Union requirements for medical device registrations.

As defined in Medical Devices Directive 93/42/EEC, the regulatory approach necessary to demonstrate to the European Union that the organization has the
ability  to  provide  medical  devices  and  related  services  that  consistently  meet  customer  requirements  and  regulatory  requirements  applicable  to  medical
devices requires the certification of a full quality management system by a notified body. Initially, we engaged TÜV Rheinland of North America, Inc.
(“TÜV Rheinland”) as the notified body to assist us in obtaining certification to ISO 13485/2003 standard, which demonstrates the presence of a quality
management  system  that  can  be  used  by  an  organization  for  design  and  development,  production,  installation  and  servicing  of  medical  devices  and  the
design, development and provision of related services.

European Union requirements for products are set forth in harmonized European Union standards and include conformity to safety requirements, physical
and biological properties, construction and environmental properties, and information supplied by the manufacturer. A company demonstrates conformity
to these requirements, with respect to a product, by pre-clinical tests, biocompatibility tests, qualification of products and packaging, risk analysis and well-
conducted clinical investigations approved by ethics committees.

Once a manufacturer’s full quality management system is determined to be in compliance with ISO 13485/2003 and other statutory requirements, and the
manufacturer’s products conform to harmonized European standards, the notified body will recommend and document such conformity. The manufacturer
will receive a CE marking and ISO certifications, and then may place a CE mark on the relevant products. The CE mark, which stands for Conformité
Européene, demonstrates compliance with the relevant European Union requirements. Products subject to these provisions that do not bear the CE mark
cannot be imported to, or sold or distributed within, the European Union.

Medical Devices sold in Europe/ anticipated to be sold in Europe, shall be examined, and classified as:

● Class I: Provided non-sterile or do not have a measuring functions; Low Risk
● Class I: Provided sterile and/or have a measuring function; Low/medium risk
● Class IIa: Medium risk
● Class IIb: Medium/high risk
● Class III: High risk

In  July  2003,  we  received  a  certification  from  TÜV  Rheinland  that  our  quality  management  system  conforms  to  the  requirements  of  the  European
Community.  At  the  same  time,  TÜV  Rheinland  approved  our  use  of  the  CE  marking  with  respect  to  the  design  and  production  of  high  permeability
hemodialyzer products for ESRD therapy. In April 2010, we changed our notified body from TÜV Rheinland to BSI America, Inc. and expanded our scope
to include design and development and production of water filters.

Under the License Agreement with Bellco, as discussed above, we granted Bellco a license to manufacture, market and sell the covered products under its
own name, label and CE mark in the stated territory. In addition, if requested by us, Bellco will be required to sell the covered products to our distributors
in the stated territory.

The following products have been certified by BSI America for CE marking and adherence to ISO13485 standards as Class IIa (Rule 3) medical devices:

● SSU-D/DSU-D Dual Stage Ultrafilter: Intended to be used to filter water or bicarbonate concentrate used in hemodialysis procedures.

Regulatory Authorities in Regions Outside of the United States and the European Union

In November 2007 and May 2011, the Therapeutic Products Directorate of Health Canada, the Canadian health regulatory agency, approved our OLpūr
MD220 Hemodiafilter and our DSU, respectively, for marketing in Canada. Other than the Canadian approval of our OLpūr MD220 Hemodiafilter and
DSU products, we have not obtained any regulatory approvals to sell any of our products outside of the United States and the European Union and there is
no assurance that any such clearance or certification will be issued.

Requirements pertaining to medical devices vary widely from country to country, ranging from no health regulations to detailed submissions such as those
required  by  the  FDA.  Our  manufacturing  facilities  are  subject  to  audits  and  have  been  certified  to  be  ISO  13485:2016  and  Medical  Device  Directive
93/42/EEC, which allows us to sell our products in the United States, Canada, and Europe.

Currently we are in the process to seek approval for MDSAP compliance. The Medical Device Single Audit Program (MDSAP) is a program that allows
the  conduct  of  a  single  regulatory  audit  of  a  medical  device  manufacturer’s  quality  management  system  that  satisfies  the  requirements  of  multiple
regulatory  jurisdictions.  Audits  are  conducted  by  Auditing  Organizations  authorized  by  the  participating  Regulatory  Authorities  to  audit  under  MDSAP
requirements. The MDSAP is a way that medical device manufacturers can be audited once for compliance with the standard and regulatory requirements
of up to five different medical device markets: Australia, Brazil, Canada, Japan, and the United States.

Following the completion of MDSAP, this certification will allow us to sell our products in the United States, Canada, Europe, and other territories around
the world, while maintaining our current approvals. The time and cost of obtaining new, and maintaining existing, market authorizations from countries
outside of North America, and the requirements for licensing products in these countries may differ significantly from FDA requirements.

Reimbursement

In  both  domestic  markets  and  markets  outside  of  the  United  States,  sales  of  our  ESRD  therapy  products  will  depend  in  part,  on  the  availability  of
reimbursement  from  third-party  payers.  In  the  United  States,  ESRD  providers  are  reimbursed  through  Medicare,  Medicaid,  and  private  insurers.  In
countries other than the United States, ESRD providers are also reimbursed through governmental insurers. In countries other than the United States, the
pricing  and  profitability  of  our  products  generally  will  be  subject  to  government  controls.  Despite  the  continually  expanding  influence  of  the  European
Union, national healthcare systems in its member nations, including reimbursement decision-making, are neither regulated nor integrated at the European
Union level. Each country has its own system, often closely protected by its corresponding national government.

Product Liability and Insurance

The production, marketing and sale of our products have an inherent risk of liability in the event of product failure or claim of harm caused by product
operation.  We  have  acquired  product  liability  insurance  for  our  products  in  the  amount  of  $2  million.  A  successful  claim  in  excess  of  our  insurance
coverage could materially deplete our assets. Moreover, any claim against us could generate negative publicity, which could decrease the demand for our
products, our ability to generate revenues and our profitability.

Some  of  our  existing  and  potential  agreements  with  manufacturers  of  our  products  and  components  of  our  products  do  or  may  require  us  (1)  to  obtain
product  liability  insurance  or  (2)  to  indemnify  manufacturers  against  liabilities  resulting  from  the  sale  of  our  products.  If  we  are  not  able  to  maintain
adequate product liability insurance, we will be in breach of these agreements, which could materially adversely affect our ability to produce our products.
Even if we are able to obtain and maintain product liability insurance, if a successful claim in excess of our insurance coverage is made, then we may have
to indemnify some or all of our manufacturers for their losses, which could materially deplete our assets.

Employees

As of December 31, 2021, we employed a total of 34 full-time employees, including 9 employed in sales/marketing/customer support, 14 in general and
administrative,  and  11  in  research  and  development.  None  of  our  employees  are  currently  represented  by  a  labor  union  or  covered  by  a  collective
bargaining  agreement  and  we  believe  that  our  relations  with  our  employees  are  good.  During  2021,  we  had  limited  voluntary  turnover  and  focused  on
maintaining our workforce throughout the COVID-19 pandemic. Going forward, we intend to focus on maintaining our current good relations with our
employees and continuing to develop and explore ways to collaborate with our employees and create a well-regarded workplace.

Available Information

We are subject to the reporting requirements of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Exchange Act requires us to
file  periodic  reports,  proxy  statements  and  other  information  with  the  SEC.  The  SEC  maintains  a  website  that  contains  reports,  proxy  and  information
statements, and other information regarding issuers that file electronically with the SEC. These materials may be obtained electronically by accessing the

Item 1A. Risk Factors

Risks Related to Our Overall Business and Operations

We have a history of operating losses and a significant accumulated deficit, and we may not achieve or maintain profitability in the future.

As of December 31, 2021, we had an accumulated deficit of $135.7 million as a result of historical operating losses. While we believe that the revenues
following the launch of our new products will help us achieve profitability, there can be no guarantee of this. We may continue to incur additional losses in
the future depending on the timing and marketplace acceptance of our products and as a result of operating expenses being higher than our gross margin
from product sales. We began sales of our first product in March 2004, and we may never realize sufficient revenues from the sale of our products or be
profitable. Each of the following factors, among others, may influence the timing and extent of our profitability, if any:

● the market acceptance of our technologies and products in each of our target markets;
● our ability to effectively and efficiently manufacture, market and distribute our products;
● our ability to sell our products at competitive prices that exceed our per unit costs; and
● our ability to continue to develop products and maintain a competitive advantage in our industry.

The COVID-19 pandemic may continue to adversely impact our sales and revenues.

There is uncertainty with respect to our projections regarding the availability of sufficient cash resources as a result of the COVID-19 pandemic and the
economic conditions it has caused. During the pandemic, we have seen decreased demand for our hospital filtration products, particularly in emergency
pathogen  outbreak  response.  In  addition,  sales  to  new  customers  –  including  water  filtration  and  pathogen  detection  products  –  have  been  hindered  by
pandemic-related travel restrictions. Also, our commercial filtration products, which are primarily targeted at the hospitality and food service markets, have
seen a decrease in demand, due to the closure or reduced occupancy of many hotels and restaurants. If these decreases in demand continue and we are
unable to achieve our revenue plan, we may cut budgeted expenditures as appropriate to preserve our available capital resources, which could slow our
revenue growth plans.

We face significant challenges in obtaining market acceptance of our products, which could adversely affect our potential sales and revenues.

We have only a limited established customer base for our products. Our failure to achieve sufficient market acceptance and sell our products at competitive
prices  will  limit  our  ability  to  generate  revenue  and  be  profitable.  Our  water  filtration  products  and  technologies  may  not  achieve  expected  reliability,
performance, and endurance standards. Our water filtration products and technologies may not achieve market acceptance, including among hospitals, or
may not be deemed suitable for other commercial, military, industrial or retail applications. Factors that may affect our ability to achieve acceptance of our
water filtration products and technologies in the marketplace include whether such products will be safe for use, whether they will be effective and whether
they will be cost-effective.

Further, acceptance of our chronic renal failure therapy products in the marketplace by both potential users, including chronic renal failure patients, and
potential  purchasers,  including  nephrologists,  dialysis  clinics  and  other  health  care  providers,  is  uncertain.  Market  acceptance  will  require  substantial
marketing  efforts  and  the  expenditure  of  significant  funds  by  us  to  inform  dialysis  patients  and  nephrologists,  dialysis  clinics  and  other  health  care
providers of the benefits of using our products. We may encounter significant clinical and market resistance to our products and our products may never
achieve market acceptance. We may not be able to build key relationships with physicians, clinical groups and government agencies, pursue or increase
sales  opportunities  in  Europe  or  elsewhere,  or  be  the  first  to  introduce  HDF  therapy  in  the  United  States.  Product  orders  may  be  cancelled,  patients  or
customers  currently  using  our  products  may  cease  to  do  so  and  patients  or  customers  expected  to  begin  using  our  products  may  not.  Additionally,
acceptance in the marketplace will depend on whether we will be able to demonstrate product safety, efficacy and cost-effectiveness, whether there are
unexpected side effects, complications or other safety issues associated with such products, and whether government or third-party reimbursement for the
cost of such products is available at reasonable rates, if at all.

18

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
If we are not able to successfully scale-up production of our products, then our sales and revenues will suffer.

In  order  to  successfully  commercialize  our  products,  we  need  to  be  able  to  produce  them  in  a  cost-effective  way  on  a  large  scale  to  meet  commercial
demand, while maintaining extremely high standards for quality and reliability. The extent to which we fail to successfully commercialize our products will
limit our ability to be profitable.

We  rely  on,  and  for  the  foreseeable  future  expect  to  continue  to  rely  on,  a  limited  number  of  independent  manufacturers  to  produce  our  products.  Our
manufacturers’ systems and procedures may not be adequate to support our operations and may not be able to achieve the rapid execution necessary to
exploit  the  market  for  our  products.  As  we  expect  to  continue  ramping  up  our  supply  requirements,  our  contracted  manufacturers  could  experience
manufacturing  and  control  problems  as  they  begin  to  scale-up  their  manufacturing  operations  to  timely  and  adequately  supply  us  with  product.  If  we
experience any of these problems with respect to our manufacturers’ scale-ups of manufacturing operations, then we may not be able to have our products
manufactured  and  delivered  in  a  timely  manner.  Our  products  are  new  and  evolving,  and  our  manufacturers  may  encounter  unforeseen  difficulties  in
manufacturing them in commercial quantities or at all.

If we cannot develop adequate distribution, customer service and technical support networks, then we may not be able to market and distribute our
products effectively and/or customers may decide not to order our products. In either case, our sales and revenues will suffer.

Our strategy requires us to distribute our products and provide a significant amount of customer service and maintenance and other technical service. To
provide these services, we have begun, and will need to continue, to develop a network of distribution and a staff of employees and independent contractors
in each of the areas in which we intend to operate. We cannot assure that we will be able to organize and manage this network on a cost-effective basis. If
we cannot effectively organize and manage this network, then it may be difficult for us to distribute our products and to provide competitive service and
support to our customers, in which case customers may be unable, or decide not, to order our products and our sales and revenues will suffer.

We have limited experience selling our products to healthcare facilities, and we might be unsuccessful in increasing our sales.

Our  business  strategy  depends  in  part  on  our  ability  to  sell  our  products  to  hospitals  and  other  healthcare  facilities,  including  dialysis  clinics.  We  have
limited experience with respect to sales and marketing. If we are unsuccessful at manufacturing, marketing, and selling our products, our operations and
potential revenues will be materially adversely affected.

Product  liability  associated  with  the  production,  marketing,  and  sale  of  our  products,  and/or  the  expense  of  defending  against  claims  of  product
liability, could materially deplete our assets and generate negative publicity which could impair our reputation.

The production, marketing and sale of kidney dialysis and water-filtration products have inherent risks of liability in the event of product failure or claim of
harm caused by product operation. Voluntary recalls could subject us to claims or proceedings by consumers, the FDA or other regulatory authorities which
may adversely impact our sales and revenues. Furthermore, even meritless claims of product liability may be costly to defend against. Although we have
acquired product liability insurance for our products, we may not be able to maintain or obtain this insurance on acceptable terms or at all. Because we may
not be able to obtain insurance that provides us with adequate protection against all potential product liability claims, a successful claim in excess of our
insurance coverage could materially deplete our assets. Moreover, even if we are able to obtain adequate insurance, any claim against us could generate
negative publicity, which could impair our reputation and adversely affect the demand for our products, our ability to generate sales and our profitability.

19

 
 
 
 
 
 
 
 
 
 
 
Some  of  the  agreements  that  we  may  enter  into  with  manufacturers  of  our  products  and  components  of  our  products  may  require  us  to  obtain  product
liability insurance; or to indemnify manufacturers against liabilities resulting from the sale of our products. For example, the agreement with our contract
manufacturer (“CM”) requires that we obtain and maintain certain minimum product liability insurance coverage and that we indemnify our CM against
certain  liabilities  arising  out  of  our  products  that  they  manufacture,  provided  they  do  not  arise  out  of  our  CM’s  breach  of  the  agreement,  negligence  or
willful misconduct. If we are not able to obtain and maintain adequate product liability insurance, then we could be in breach of these agreements, which
could materially adversely affect our ability to produce our products and generate revenues. Even if we are able to obtain and maintain product liability
insurance, if a successful claim in excess of our insurance coverage is made, then we may have to indemnify some or all of our manufacturers for their
losses, which could materially deplete our assets.

We cannot assure you that our products will be safe or that there will not be product-related deaths, serious injuries or product malfunctions. Further,
we are required under applicable law to report any circumstances relating to our medically approved products that could result in deaths or serious
injuries. These circumstances could trigger recalls, class action lawsuits and other events that could cause us to incur expenses and may also limit our
ability to generate revenues from such products.

We cannot assure you that our products will prove to be safe or that there will not be product-related deaths or serious injuries or product malfunctions,
which could trigger recalls, class action lawsuits and other events that could cause us to incur significant expenses, limit our ability to market our products
and generate revenues from such products or cause us reputational harm. Under the FDC Act, we are required to submit medical device reports (“MDRs”)
to the FDA to report device-related deaths, serious injuries and malfunctions of medically approved products that could result in death or serious injury if
they were to recur. Depending on their significance, MDRs could trigger events that could cause us to incur expenses and may also limit our ability to
generate revenues from such products. Additionally, any of the following could occur:

● information contained in the MDRs could trigger FDA regulatory actions such as inspections, recalls and patient/physician notifications;
● because the reports are publicly available, MDRs could become the basis for private lawsuits, including class actions; and
● if we fail to submit a required MDR to the FDA, the FDA could take enforcement action against us.

If any of these events occur, then we could incur significant expenses and it could become more difficult for us to market and sell our products and to
generate revenues from sales. Other countries may impose analogous reporting requirements that could cause us to incur expenses and may also limit our
ability to generate revenues from sales of our products.

We may face significant risks associated with international operations, which could have a material adverse effect on our business, financial condition,
and results of operations.

We expect to manufacture and to market our products globally. Our international operations are subject to a number of risks, including the following:

● fluctuations in exchange rates of the U.S. dollar could adversely affect our results of operations;
● we may face difficulties in enforcing and collecting accounts receivable under some countries’ legal systems;
● local regulations may restrict our ability to sell our products, have our products manufactured or conduct other operations;
● political instability could disrupt our operations;
● some governments and customers may have longer payment cycles, with resulting adverse effects on our cash flow; and
● some countries could impose additional taxes or restrict the import of our products.

Any one or more of these factors could increase our costs, reduce our revenues, or disrupt our operations, which could have a material adverse effect on our
business, financial condition, and results of operations.

20

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Risks Related to Government Regulation

If we violate any provisions of the FDC Act or any other statutes or regulations, then we could be subject to enforcement actions by the FDA or other
governmental agencies.

We face a significant compliance burden under the FDC Act and other applicable statutes and regulations which govern the testing, labeling, storage, record
keeping,  distribution,  sale,  marketing,  advertising  and  promotion  of  our  medically  approved  products.  If  we  violate  the  FDC  Act  or  other  regulatory
requirements (either with respect to our ultrafilters or otherwise) at any time during or after the product development and/or approval process, we could be
subject to enforcement actions by the FDA or other agencies, including:

● fines;
● injunctions;
● civil penalties;
● recalls or seizures of products;
● total or partial suspension of the production of our products;
● withdrawal of any existing approvals or pre-market clearances of our products;
● refusal to approve or clear new applications or notices relating to our products;
● recommendations that we not be allowed to enter into government contracts; and
● criminal prosecution.

Any of the above could have a material adverse effect on our business, financial condition, and results of operations.

We cannot sell our products, including certain modifications thereto, until we obtain the requisite regulatory approvals and clearances in the countries
in which we intend to sell our products. If we fail to receive, or experience a significant delay in receiving, such approvals and clearances, then we may
not be able to get our products to market and enhance our revenues.

Our business strategy depends in part on our ability to get our products into the market as quickly as possible. We have obtained a Conformité Européene
(“CE”) mark, which demonstrates compliance with the relevant European Union requirements and is a regulatory prerequisite for selling our products in
the European Union and certain other countries that recognize CE marking (collectively, “European Community”), for our OLpūr MD 220 Hemodiafilter
and our DSU. We have not yet obtained a CE mark for any of our other products. We previously received clearance from the FDA to market our OLpūr
MD220  Hemodiafilter  and  OLpūr  H2H  Module  for  use  with  a  hemodialysis  machine  that  provides  ultrapure  dialysate  in  accordance  with  current
ANSI/AAMI/ISO  standards,  for  the  treatment  of  chronic  renal  failure  patients.  We  have  not  begun  to  broadly  market  these  products  and  are  actively
seeking a commercialization partner in the United States.

We  cannot  ensure  that  any  existing  products  that  have  not  yet  been  approved,  or  any  new  products  developed  by  us  in  the  future,  will  be  approved  for
marketing. The clearance and/or approval processes can be lengthy and uncertain, and each requires substantial commitments of our financial resources and
our management’s time and effort. We may not be able to obtain further CE marking or regulatory approval for any of our existing or new products in a
timely manner or at all. Even if we do obtain regulatory approval, approval may be only for limited uses with specific classes of patients, processes, or
other devices. Our failure to obtain, or delays in obtaining, the necessary regulatory clearance and/or approvals would prevent us from selling our affected
products in the applicable regions. If we cannot sell some of our products in such regions, or if we are delayed in selling while waiting for the necessary
clearance and/or approvals, our ability to generate revenues from these products will be limited.

Over time, we intend to market our products globally. Requirements pertaining to the sale of our products vary widely from country to country. It may be
very expensive and difficult for us to meet the requirements for the sale of our products in many countries. As a result, we may not be able to obtain the
required approvals in a timely manner, if at all. If we cannot sell our products in a particular region, then the size of our potential market could be reduced,
which would limit our potential sales and revenues.

21

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Significant additional governmental regulation could subject us to unanticipated delays that would adversely affect our sales and revenues.

Our business strategy depends in part on our ability to get our products into the market as quickly as possible. Additional laws and regulations, or changes
to existing laws and regulations that are applicable to our business may be enacted or promulgated, and the interpretation, application or enforcement of the
existing laws and regulations may change. We cannot predict the nature of any future laws, regulations, interpretations, applications or enforcements or the
specific effects any of these might have on our business. Any future laws, regulations, interpretations, applications, or enforcements could delay or prevent
regulatory approval or clearance of our products and our ability to market our products. Moreover, changes that result in our failure to comply with the
requirements of applicable laws and regulations could result in enforcement actions by the FDA and/or other agencies, all of which could impair our ability
to have manufactured and to sell the affected products.

If we are not able to maintain sufficient quality controls, then the approval or clearance of our products by the European Union, the FDA or other
relevant authorities could be withdrawn, delayed or denied and our sales and revenues will suffer.

Approval  or  clearance  of  our  products  could  be  withdrawn,  delayed,  or  denied  by  the  European  Union,  the  FDA  and  the  relevant  authorities  of  other
countries if our manufacturing facilities do not comply with their respective manufacturing requirements. The European Union imposes requirements on
quality control systems of manufacturers, which are inspected and certified on a periodic basis and may be subject to additional unannounced inspections.
Failure by our manufacturers to comply with these requirements could prevent us from marketing our products in the European Community. The FDA also
imposes  requirements  through  quality  system  requirements  regulations,  which  include  requirements  for  good  manufacturing  practices.  Failure  by  our
manufacturers to comply with these requirements could prevent us from obtaining FDA pre-clearance or approval of our products and from marketing such
products in the United States. Although the manufacturing facilities and processes that we use to manufacture our OLpūr MD HDF filter series have been
inspected  and  certified  by  a  worldwide  testing  and  certification  agency  (also  referred  to  as  a  notified  body)  that  performs  conformity  assessments  to
European Union requirements for medical devices, they have not been inspected by the FDA. A “notified body” is a group accredited and monitored by
governmental agencies that inspects manufacturing facilities and quality control systems at regular intervals and is authorized to carry out unannounced
inspections. We cannot be sure that any of the facilities or processes we use will comply or continue to comply with their respective requirements on a
timely basis or at all, which could delay or prevent our obtaining the approvals we need to market our products in the European Community and the United
States.

To market our products in the European Community, the United States, and other countries, where approved, manufacturers of such products must continue
to comply or ensure compliance with the relevant manufacturing requirements. Although we cannot control the manufacturers of our products, we may
need to expend time, resources and effort in product manufacturing and quality control to assist with their continued compliance with these requirements. If
violations of applicable requirements are noted during periodic inspections of the manufacturing facilities of our manufacturers, then we may not be able to
continue to market the products manufactured in such facilities and our revenues may be materially adversely affected.

Clinical studies that may be required for our products are costly and time-consuming, and their outcome is uncertain.

Before  obtaining  regulatory  approvals  for  the  commercial  sale  of  any  of  our  products,  other  than  those  for  which  we  have  already  received  marketing
approval in the United States and elsewhere, we must demonstrate through clinical studies that our products are safe and effective.

For products other than those for which we have already received marketing approval, if we do not prove in clinical trials that our products are safe and
effective, we will not obtain marketing approvals from the applicable regulatory authorities. In particular, one or more of our products may not exhibit the
expected medical benefits, may cause harmful side effects, may not be effective in treating dialysis patients, or may have other unexpected characteristics
that preclude regulatory approval for any or all indications of use or limit commercial use if approved. The length of time necessary to complete clinical
trials varies significantly and is difficult to predict. Factors that can cause delay or termination of our clinical trials include:

● slower than expected patient enrollment due to the nature of the protocol, the proximity of subjects to clinical sites, the eligibility criteria for the

study, competition with clinical trials for similar devices or other factors;

● lower than expected retention rates of subjects in a clinical trial;
● inadequately trained or insufficient personnel at the study site to assist in overseeing and monitoring clinical trials;
● delays in approvals from a study site’s review board, or other required approvals;

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● longer treatment time required to demonstrate effectiveness;
● lack of sufficient supplies of the product;
● adverse medical events or side effects in treated subjects; and
● lack of effectiveness of the product being tested.

Even if we obtain positive results from clinical studies for our products, we may not achieve the same success in future studies of such products. Data
obtained from clinical studies is susceptible to varying interpretations that could delay, limit, or prevent regulatory approval. In addition, we may encounter
delays or rejections based upon changes in regulatory policy for device approval during the period of product development and regulatory review of each
submitted  new  device  application.  Moreover,  regulatory  approval  may  entail  limitations  on  the  indicated  uses  of  the  device.  Failure  to  obtain  requisite
governmental approvals or failure to obtain approvals of the scope requested will delay or preclude our licensees or marketing partners from marketing our
products or limit the commercial use of such products and will have a material adverse effect on our business, financial condition, and results of operations.

In addition, some, or all of the clinical trials we undertake may not demonstrate sufficient safety and efficacy to obtain the requisite regulatory approvals,
which could prevent or delay the creation of marketable products. Our product development costs will increase if we have delays in testing or approvals, if
we  need  to  perform  more,  larger  or  different  clinical  trials  than  planned  or  if  our  trials  are  not  successful.  Delays  in  our  clinical  trials  may  harm  our
financial results and the commercial prospects for our products. Additionally, we may be unable to complete our clinical trials if we are unable to obtain
additional capital.

Risks Related to our Intellectual Property

Protecting our intellectual property in our technology through patents may be costly and ineffective. If we are not able to adequately secure or enforce
protection of our intellectual property, then we may not be able to compete effectively and we may not be profitable.

Our future success depends in part on our ability to protect the intellectual property for our technology through patents. We will only be able to protect our
products and methods from unauthorized use by third parties to the extent that our products and methods are covered by valid and enforceable patents or
are  effectively  maintained  as  trade  secrets.  Our  11  granted  U.S.  patents  will  expire  at  various  times  from  2022  to  2040,  assuming  they  are  properly
maintained.

The  protection  provided  by  our  patents,  and  patent  applications  if  issued,  may  not  be  broad  enough  to  prevent  competitors  from  introducing  similar
products  into  the  market.  Our  patents,  if  challenged  or  if  we  attempt  to  enforce  them,  may  not  necessarily  be  upheld  by  the  courts  of  any  jurisdiction.
Numerous publications may have been disclosed by, and numerous patents may have been issued to, our competitors and others relating to methods and
devices for dialysis of which we are not aware and additional patents relating to methods and devices for dialysis may be issued to our competitors and
others in the future. If any of those publications or patents conflict with our patent rights, or cover our products, then any or all of our patent applications
could be rejected and any or all of our granted patents could be invalidated, either of which could materially adversely affect our competitive position.

Litigation and other proceedings relating to patent matters, whether initiated by us or a third party, can be expensive and time-consuming, regardless of
whether the outcome is favorable to us, and may require the diversion of substantial financial, managerial, and other resources. An adverse outcome could
subject us to significant liabilities to third parties or require us to cease any related development, product sales or commercialization activities. In addition,
if  patents  that  contain  dominating  or  conflicting  claims  have  been  or  are  subsequently  issued  to  others  and  the  claims  of  these  patents  are  ultimately
determined to be valid, then we may be required to obtain licenses under patents of others in order to develop, manufacture, use, import and/or sell our
products. We may not be able to obtain licenses under any of these patents on terms acceptable to us, if at all. If we do not obtain these licenses, we could
encounter delays in, or be prevented entirely from using, importing, developing, manufacturing, offering, or selling any products or practicing any methods,
or delivering any services requiring such licenses.

If we file for or obtain additional patents in foreign countries, we will be subject to laws and procedures that differ from those in the United States. Such
differences could create additional uncertainty about the level and extent of our patent protection. Moreover, patent protection in foreign countries may be
different  from  patent  protection  under  U.S.  laws  and  may  not  be  as  favorable  to  us.  Many  non-U.S.  jurisdictions,  for  example,  prohibit  patent  claims
covering methods of medical treatment of humans, although this prohibition may not include devices used for such treatment.

If we are not able to secure and enforce protection of our trade secrets through enforcement of our confidentiality and non-competition agreements,
then our competitors may gain access to our trade secrets, we may not be able to compete effectively, and we may not be profitable. Such protection may
be costly and ineffective.

We attempt to protect our trade secrets, including the processes, concepts, ideas, and documentation associated with our technologies, through the use of
confidentiality  agreements  and  non-competition  agreements  with  our  current  employees  and  with  other  parties  to  whom  we  have  divulged  such  trade
secrets. If these employees or other parties breach our confidentiality agreements and non-competition agreements, or if these agreements are not sufficient
to protect our technology or are found to be unenforceable, then our competitors could acquire and use information that we consider to be our trade secrets
and we may not be able to compete effectively. Policing unauthorized use of our trade secrets is difficult and expensive and, in the event, we further expand
our operations, the laws of other countries may not adequately protect our trade secrets.

Risks Related to Owning Our Common Stock

Our common stock could be further diluted as a result of the issuance of additional shares of common stock, warrants or options.

In the past we have issued common stock and warrants in order to raise capital to help fund our business. We have also issued stock options and restricted
stock as compensation for services and incentive compensation for our employees, directors, and consultants. We have shares of common stock reserved
for issuance upon the exercise of certain of these securities and may increase the shares reserved for these purposes in the future. Our issuance of additional
common stock, options and warrants could affect the rights of our stockholders, could reduce the market price of our common stock, or could obligate us to
issue additional shares of common stock.

Market sales of large amounts of our common stock, or the potential for those sales even if they do not actually occur, may have the effect of depressing the
market price of our common stock, the supply of common stock available for resale could be increased which could stimulate trading activity and cause the
market price of our common stock to drop, even if our business is doing well. Furthermore, the issuance of any additional shares of our common stock or
securities convertible into our common stock could be substantially dilutive to holders of our common stock if they do not invest in future offerings.

The prices at which shares of the common stock trade have been and will likely continue to be volatile.

During the two years ended December 31, 2021, our common stock has traded at prices ranging from a high of $11.67 to a low of $4.42 per share. Due to
the lack of an active trading market for our common stock, we expect the prices at which our common stock might trade to continue to be highly volatile.
The expected volatile price of our stock will make it difficult for investors to predict the value of an investment in our common stock, to sell shares at a
profit at any given time, or to plan purchases and sales in advance. A variety of other factors might also affect the market price of our common stock. These
include, but are not limited to:

● achievement or rejection of regulatory approvals by our competitors or us;
● publicity regarding actual or potential clinical or regulatory results relating to products under development by our competitors or us;
● delays or failures in initiating, completing, or analyzing clinical trials or the unsatisfactory design or results of these trials;
● announcements of technological innovations or new commercial products by our competitors or us;
● developments concerning proprietary rights, including patents;
● regulatory developments in the United States and foreign countries;
● economic or other crises and other external factors;
● period-to-period fluctuations in our results of operations;
● threatened or actual litigation;
● changes in financial estimates by securities analysts; and
● sales of our common stock.

24

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We are not able to control many of these factors, and we believe that period-to-period comparisons of our financial results will not necessarily be indicative
of our future performance.

We have never paid dividends and do not intend to pay cash dividends.

We have never paid dividends on our common stock and currently do not anticipate paying cash dividends on our common stock for the foreseeable future.
Consequently, any returns on an investment in our common stock in the foreseeable future will have to come from an increase in the value of the stock
itself. As noted above, the lack of an active trading market for our common stock will make it difficult to value and sell our common stock. While our
dividend policy will be based on the operating results and capital needs of our business, we anticipate that all earnings, if any, will be retained to finance
our future operations.

Several  provisions  of  the  Delaware  General  Corporation  Law,  our  fourth  amended  and  restated  certificate  of  incorporation,  as  amended,  and  our
second amended and restated bylaws could discourage, delay or prevent a merger or acquisition, which could adversely affect the market price of our
common stock.

Several provisions of the Delaware General Corporation Law, our fourth amended and restated certificate of incorporation, as amended, and our second
amended and restated bylaws could discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, and the market price of
our common stock could be reduced as a result. These provisions include:

● authorizing our board of directors to issue “blank check” preferred stock without stockholder approval;
● providing for a classified board of directors with staggered, three-year terms;
● prohibiting  us  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 certain provisions are met;

● prohibiting cumulative voting in the election of directors;
● limiting the persons who may call special meetings of stockholders; and
● establishing advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted on by

stockholders at stockholder meetings.

As a smaller reporting company with little or no name recognition and with several risks and uncertainties that could impair our business operations,
we are not likely to generate widespread interest in our common stock. Without widespread interest in our common stock, our common stock price may
be highly volatile and an investment in our common stock could decline in value.

Unlike  many  companies  with  publicly  traded  securities,  we  have  little  or  no  name  recognition  in  the  investment  community.  We  are  a  relatively  new
company and very few investors are familiar with either our company or our products. We do not have an active trading market in our common stock, and
one might never develop, or if it does develop, might not continue.

Additionally, the market price of our common stock may fluctuate significantly in response to many factors, many of which are beyond our control. Risks
and uncertainties, including those described elsewhere in this “Risk Factors” section could impair our business operations or otherwise cause our operating
results or prospects to be below expectations of investors and market analysts, which could adversely affect the market price of our common stock. As a
result, investors in our common stock may not be able to resell their shares at or above their purchase price and could lose all of their investment.

Securities class action litigation is often brought against public companies following periods of volatility in the market price of such company’s securities.
We may become subject to this type of litigation in the future. Litigation of this type could be extremely expensive and divert management’s attention and
resources from running our company.

Our directors, executive officers, and Wexford Capital LP (“Wexford”) control a significant portion of our stock and, if they choose to vote together,
could have sufficient voting power to control the vote on substantially all corporate matters.

As  of  February  23,  2022,  Wexford,  our  largest  stockholder,  beneficially  owned  approximately  36%  of  our  outstanding  common  stock.  Collectively,
Wexford, our directors and our executive officers beneficially owned approximately 40% of our outstanding common stock. As a result of this ownership,
Wexford has the ability to exert significant influence over our policies and affairs, including the election of directors. Wexford, whether acting alone or
acting with other stockholders, could have the power to elect all of our directors and to control the vote on substantially all other corporate matters without
the  approval  of  other  stockholders.  Furthermore,  such  concentration  of  voting  power  could  enable  Wexford,  whether  acting  alone  or  acting  with  other
stockholders, to delay or prevent another party from taking control of our company even where such change of control transaction might be desirable to
other stockholders. The interests of Wexford in any matter put before the stockholders may differ from those of any other stockholder.

Future sales of our common stock could cause the market price of our common stock to decline.

The market price of our common stock could decline due to sales of a large number of shares in the market, including sales of shares by Wexford or any
other  large  stockholder,  or  the  perception  that  such  sales  could  occur.  These  sales  could  also  make  it  more  difficult  or  impossible  for  us  to  sell  equity
securities in the future at a time and price that we deem appropriate to raise funds through future offerings of common stock. Future sales of our common
stock by stockholders could depress the market price of our common stock.

The following discussion includes forward-looking statements about our business, financial condition and results of operations including discussions about
management’s  expectations  for  our  business.  These  statements  represent  projections,  beliefs  and  expectations  based  on  current  circumstances  and
conditions and in light of recent events and trends, and these statements should not be construed either as assurances of performances or as promises of a
given course of action. Instead, various known and unknown factors are likely to cause our actual performance and management’s actions to vary, and the
results  of  these  variances  may  be  both  material  and  adverse.  A  list  of  the  known  material  factors  that  may  cause  our  results  to  vary,  or  may  cause
management to deviate from its current plans and expectations, is included in Item 1A, “Risk Factors,” of this Annual Report on Form 10-K. The following
discussion  should  also  be  read  in  conjunction  with  the  consolidated  financial  statements  and  notes  included  in  Item  8,  “Financial  Statements  and
Supplemental Data,” of this Annual Report on Form 10-K.

Business Overview

We are a commercial-stage company that develops and sells high performance water solutions to the medical and commercial markets.

In medical markets, we sell water filtration products and waterborne pathogen detection products. Our medical water filters, mostly classified as ultrafilters,
are used primarily by hospitals for the prevention of infection from waterborne pathogens, such as legionella and pseudomonas, and in dialysis centers for
the removal of biological contaminants from water and bicarbonate concentrate. Because our ultrafilters capture contaminants as small as 0.005 microns in
size, they minimize exposure to a wide variety of bacteria, viruses, fungi, parasites, and endotoxins.

In commercial markets, we manufacture and sell water filters that improve the taste and odor of water and reduce biofilm, bacteria, and scale build-up in
downstream  equipment.  Marketed  under  both  the  Nephros  and  AETHER  brands,  our  products  are  marketed  primarily  to  the  food  service,  hospitality,
convenience store, and health care markets.

Our pathogen detection systems are portable, near real-time systems designed to provide actionable data for infection control teams, biomedical engineers
in dialysis clinics, and water quality teams in building management organizations.

We  also  have  a  subsidiary,  Specialty  Renal  Products,  Inc.  (“SRP”),  a  development-stage  medical  device  company,  focused  primarily  on  developing
hemodiafiltration  (“HDF”)  technology.  SRP  is  developing  a  second-generation  of  the  Nephros  OLpūr  H2H  Hemodiafiltration  System,  the  FDA  510(k)-
cleared medical device that enables nephrologists to provide HDF treatment to patients with end stage renal disease (“ESRD”).

We were founded in 1997 by healthcare professionals affiliated with Columbia University Medical Center/New York-Presbyterian Hospital to develop and
commercialize  an  alternative  method  to  hemodialysis.  We  have  extended  our  filtration  technologies  to  meet  the  demand  for  liquid  purification  in  other
areas, in particular, water purification.

Recent Accounting Pronouncements

We  are  subject  to  recently  issued  accounting  standards,  accounting  guidance  and  disclosure  requirements.  For  a  description  of  these  new  accounting
standards, see “Note 2 – Summary of Significant Accounting Policies,” to our consolidated financial statements included in Item 8, “Financial Statements
and Supplementary Data,” of this Annual Report on Form 10-K.

Critical Accounting Policies and Estimates

Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared
in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of financial statements in accordance with
GAAP requires application of management’s subjective judgments, often requiring estimates about the effect of matters that are inherently uncertain and
may change in subsequent periods. Our actual results may differ substantially from these estimates under different assumptions or conditions. While our
significant  accounting  policies  are  described  in  more  detail  in  “Note  2  –  Summary  of  Significant  Accounting  Policies,”  to  our  consolidated  financial
statements  included  in  Item  8,  “Financial  Statements  and  Supplementary  Data,”  of  this  Annual  Report  on  Form  10-K,  we  believe  that  the  following
accounting policies require the application of significant judgments and estimates.

Inventories

Our inventory reserve requirements are based on various factors including product expiration date and estimates for the future sales of the product. Reserve
assessments include inventory obsolescence based upon expiration date, damaged, or rejected product, slow-moving products, and other considerations.
During  the  year  ended  December  31,  2021,  inventory  reserves  increased  $0.2  million  to  $0.3  million  primarily  due  to  expiration  of  products  that  were
manufactured  in  advance  of  demand,  and  which  expired  before  sales  began  to  accelerate.  We  continue  to  monitor  our  inventory  reserves  amounts  and
policies, and to update both as required by relevant circumstances.

Results of Operations

Fluctuations in Operating Results

Our results of operations have fluctuated significantly from period to period in the past and are likely to continue to do so in the future. We anticipate that
our annual results of operations will be impacted for the foreseeable future by several factors, including the progress and timing of expenditures related to
our research and development efforts, marketing expenses related to product launches, timing of regulatory approval of our various products and market
acceptance of our products. Due to these fluctuations, we believe that the period-to-period comparisons of our operating results are not a good indication of
our future performance.

December  31,  2021.  The  decrease  of  approximately  2%  was  driven  by  the  Water  Filtration  segment  primarily  as  a  result  of  an  increase  in  inventory
obsolescence.

Consolidated selling, general and administrative expenses increased $1.2 million primarily due to increased headcount related expenditures of $1.2 million
and increased travel and marketing expenses of $0.2 million in the Water Filtration segment. This increase was partially offset by a decrease in headcount
related expenditures of $0.2 million in the Renal Products segment.

Interest Expense

Interest expense was approximately $41,000 for the year ended December 31, 2021 compared to $110,000 for the year ended December 31, 2020. Both
expenses  included  our  secured  note  payable.  The  $69,000  reduction  is  primarily  due  to  elimination  of  both  our  secured  revolving  credit  facility  and
contingent consideration accretion expense.

Extinguishment of PPP loan

Our outstanding PPP loan was forgiven in January 2021 resulting in an extinguishment of approximately $482,000.

We operate under an Investment, Risk Management and Accounting Policy adopted by our Board of Directors. Such policy limits the types of instruments
or securities in which we may invest our excess funds: U.S. Treasury Securities; Certificates of Deposit issued by money center banks; Money Funds by
money center banks; Repurchase Agreements; and Eurodollar Certificates of Deposit issued by money center banks. This policy provides that our primary
objectives  for  investments  are  the  preservation  of  principal  and  achieving  sufficient  liquidity  to  meet  our  forecasted  cash  requirements.  In  addition,
provided that such primary objectives are met, we may seek to achieve the maximum yield available under such constraints.

At December 31, 2021, we had an accumulated deficit of $135.7 million, and we expect to incur additional operating losses from operations until such
time, if ever, that we are able to increase product sales and/or licensing revenue to achieve profitability.

Based on cash that is available for our operations and projections of our future operations, we believe that our cash balances will be sufficient to fund our
current operating plan through at least the next twelve months from the date of issuance of the consolidated financial statements in this Annual Report on
Form 10-K. Additionally, our operating plans are designed to help control operating costs, to increase revenue and to raise additional capital until such time
as  we  generate  sufficient  cash  flows  from  operations.  If  there  were  a  decrease  in  the  demand  for  our  products  due  to  either  economic  or  competitive
conditions, or we are unable to achieve our plan, there could be a significant reduction in liquidity due to our possible inability to cut costs sufficiently.

Our future liquidity sources and requirements will depend on many factors, including:

● the market acceptance of our products, and our ability to effectively and efficiently produce and market our products;
● the continued progress in, and the costs of, clinical studies and other research and development programs;
● the costs involved in filing and enforcing patent claims and the status of competitive products; and
● the cost of litigation, including potential patent litigation and any other actual or threatened litigation.

We expect to put our current capital resources to the following uses:

● the development, marketing, and sales of our water-filtration and water diagnostics product;
● the development of our second-generation HDF product; and
● working capital purposes.

Net cash used in operating activities was $1.4 million for the year ended December 31, 2021 compared to $6.9 million for the year ended December 31,
2020, a decrease of $5.5 million. The decrease of $5.5 million is due primarily to decreased expenditures on inventory, which were incurred in the first half
of fiscal year 2020 to reduce the risk of possible supply chain interruptions early in the COVID-19 pandemic, and an increase in revenue for the year ended
December 31, 2021 compared to the year ended December 31, 2020.

Net cash used in investing activities was $0.1 million for the year ended December 31, 2021 compared to $0.2 million for the year ended December 31,
2021. The change is due primarily due to decreased purchases of property and equipment.

Net cash provided by financing activities of $0.2 million for the year ended December 31, 2021 resulted from proceeds from the exercise of warrants and
stock options of $0.5 million partially offset by payments on our secured note payable of $0.3 million.

Net cash provided by financing activities of $11.2 million for the year ended December 31, 2020 resulted from net proceeds from the issuance of common
stock of $11.5 million, proceeds from a PPP loan of $0.5 million and proceeds from the exercise of warrants and stock options of $0.2 million, partially
offset  by  net  payments  on  our  secured  revolving  credit  facility  of  $0.6  million,  payments  on  our  secured  note  payable  of  $0.2  million  and  payment  of
contingent consideration related to the Aether Acquisition of $0.1 million.

Purchase Commitments

In exchange for the rights granted under the License and Supply Agreement with Medica, we agreed to make certain minimum annual aggregate purchases
from Medica over the term of the License and Supply Agreement. For the year ended December 31, 2021, the Company agreed to make minimum annual
aggregate  purchases  from  Medica  of  €3.3  million  (approximately  $3.9  million).  For  the  year  ended  December  31,  2021,  the  aggregate  purchase
commitments totaled €3.5 million (approximately $4.2 million).

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
Nephros, Inc.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Nephros, Inc. and Subsidiaries (the “Company”) as of December 31, 2021 and 2020, and
the related consolidated statements of operations and comprehensive loss, changes in stockholders’ equity, and cash flows for each of the two years in the
period ended December 31, 2021, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated
financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2021 and 2020, and the results of its
operations and its cash flows for each of the two years in the period ended December 31, 2021, in conformity with accounting principles generally accepted
in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s
consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board
(United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the
applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable
assurance  about  whether  the  consolidated  financial  statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  The  Company  is  not
required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain
an  understanding  of  internal  control  over  financial  reporting,  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the  Company’s
internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or
fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and
disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by
management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis
for our opinion.

Critical Audit Matters

The  critical  audit  matter  communicated  below  is  a  matter  arising  from  the  current  period  audit  of  the  consolidated  financial  statements  that  was
communicated or required to be communicated to the audit committee and that (i) relates to accounts or disclosures that are material to the consolidated
financial statements and (ii) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not
alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below,
providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Excess and Obsolete Inventory Reserve

As described in Note 2 to the financial statements, inventory consists of finished goods and raw materials and is valued at the lower of cost or net realizable
value using the first-in, first-out method. The Company’s inventory reserve requirements are based on various factors including product expiration date and
estimates for the future sales of the product. Reserve assessments include inventory obsolescence based upon expiration date, damaged, or rejected product,
slow-moving products, and other considerations.

We identified the assessment of the excess and obsolete inventory reserve as a critical audit matter. The principal consideration for our determination that
this is a critical audit matter is the significant judgment by management to estimate the excess and obsolete inventory reserve, which led to a high degree of
auditor judgment, subjectivity and effort in performing procedures to evaluate management’s significant assumptions.

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

● testing management’s process for estimating the excess and obsolete inventory reserve, including evaluating the appropriateness of the approach

utilized and underlying assumptions

● testing the mathematical accuracy of the excess and obsolete inventory reserve calculation
● testing the completeness and accuracy of underlying data used in the analysis, including historical usage and inventory age
● developing an  independent  expectation  of  management’s  estimate,  by  performing  sensitivity  analyses  to  evaluate  changes  in  the  estimate  that

result from changes in management’s significant assumptions

NEPHROS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note 1 - Organization and Nature of Operations

Nephros, Inc. (“Nephros” or the “Company”) was incorporated under the laws of the State of Delaware on April 3, 1997. The Company was founded by
health  professionals,  scientists  and  engineers  affiliated  with  Columbia  University  to  develop  advanced  end  stage  renal  disease  (“ESRD”)  therapy
technology and products.

Beginning in 2009, Nephros introduced high performance liquid purification filters to meet the demand for water purification in certain medical markets.
The Company’s filters, generally classified as ultrafilters, are primarily used in hospitals for the prevention of infection from waterborne pathogens, such as
legionella and pseudomonas, and in dialysis centers for the removal of biological contaminants from water and bicarbonate concentrate. The Company also
develops and sells water filtration products for commercial applications, focusing on the hospitality and food service markets. The water filtration business
is a reportable segment, referred to as the Water Filtration segment.

The Company’s pathogen detection systems are portable, near real-time systems designed to provide actionable data for infection control teams and other
organizations. The pathogen detection systems business is a reportable segment, referred to as the Pathogen Detection segment.

In  July  2018,  the  Company  formed  a  new  subsidiary,  Specialty  Renal  Products,  Inc.  (“SRP”),  to  drive  the  development  of  its  second-generation
hemodiafiltration system and other products focused on improving therapies for patients with renal disease. The Company transferred three patents to SRP,
which were carried at zero book value. SRP is a reportable segment, referred to as the Renal Products segment.

The Company’s primary U.S. facilities are located at 380 Lackawanna Place, South Orange, New Jersey 07079, 3221 Polaris Avenue, Las Vegas, Nevada
89102 and 1015 Telegraph Street, Unit B, Reno, Nevada 89502. These locations house the Company’s corporate headquarters, research, manufacturing,
and distribution facilities. In addition, the Company maintains small administrative offices in various locations in the United States and Ireland.

Note 2 - Summary of Significant Accounting Policies

Principles of Consolidation and Basis of Presentation

The  accompanying  consolidated  financial  statements  include  the  accounts  of  Nephros,  Inc.  and  its  subsidiaries,  including  SRP,  in  which  a  controlling
interest  is  maintained  by  the  Company.  Outside  stockholders’  interest  in  SRP  of  37.5%  is  shown  on  the  consolidated  balance  sheet  as  noncontrolling
interest. All intercompany accounts and transactions were eliminated in the preparation of the accompanying consolidated financial statements.

Use of Estimates

The  preparation  of  consolidated  financial  statements  in  conformity  with  accounting  principles  generally  accepted  in  the  United  States  of  America
(“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent
assets and liabilities, at the date of the financial statements, and the reported amount of revenues and expenses, during the reporting period. Actual results
could differ materially from those estimates. Included in these estimates are assumptions about the collection of accounts receivable, value of inventories,
useful life of fixed assets and intangible assets, the assessment of expected cash flows used in evaluating goodwill and other long-lived assets, value of
contingent consideration, the assessment of the ability to continue as a going concern and assumptions used in determining stock compensation such as
expected volatility and risk-free interest rate.

Liquidity

The Company has sustained operating losses and expects such losses to continue over the next several quarters. In addition, net cash from operations has
been negative since inception, generating an accumulated deficit of $135.7 million as of December 31, 2021.

On September 5, 2018, SRP completed a private placement transaction whereby SRP sold preferred shares equivalent to 37.5% of its outstanding equity
interests  for  aggregate  proceeds  of  $3.0 million.  As  of  approximately  July  1,  2020,  SRP  had  fully  spent  the  proceeds  from  this  private  placement.  On
October 9, 2020, Nephros and SRP entered into a loan agreement under which Nephros agreed to lend up to $1.3 million to SRP, including the $1.0 million
borrowed during the year ended December 31, 2020. These funds are to be used to fund SRP’s operating activities and are expected to be sufficient to fund
SRP through the planned FDA 510(k) clearance process of SRP’s second-generation hemodiafiltration system, which was initially submitted to the FDA
for  “Special  510(k)”  clearance  in  February  2021  and  resubmitted  for  “Traditional  510(k)”  clearance  in  June  2021.  As  of  December  31,  2021,  the
outstanding balance, including accrued interest, was $1.3 million.

Based on cash that is available for the Company’s operations and projections of future Company operations, the Company believes that its cash balances
will be sufficient to fund its current operating plan – including any remaining negative impact of the COVID-19 pandemic – through at least the next 12
months from the date of issuance of the accompanying consolidated financial statements. Additionally, the Company’s operating plans are designed to help
control operating costs and to increase revenue until such time as the Company generates sufficient cash flows from operations.

While significant progress has been made against the COVID-19 pandemic, some uncertainty remains with respect to the Company’s projections regarding
the availability of sufficient cash resources, due to the possibility that COVID-19 infections could increase again and cause further disruption to economic
conditions.  During  the  pandemic,  particularly  during  calendar  year  2020,  the  Company  saw  decreased  demand  for  its  hospital  filtration  products,
particularly in emergency pathogen outbreak response. In addition, sales to new customers – including water filtration and pathogen detection products –
were hindered by pandemic-related travel restrictions. Also, the Company’s commercial filtration products, which are primarily targeted at the hospitality
and  food  service  markets,  saw  a  decrease  in  demand,  due  to  the  closure  of  many  hotels  and  restaurants.  The  Company  believes  that  broad  vaccine
distribution  and  increased  population  immunity  has  reduced  the  probability  of  further  significant  negative  COVID-19  impacts,  but  if  these  decreases  in
demand return and the Company is unable to achieve its revenue plan, the Company may need to reduce budgeted expenditures as appropriate to preserve
its available capital resources, which could slow its revenue growth plans.

Recently Adopted Accounting Pronouncements

In December 2019, the FASB issued Accounting Standards Update (“ASU”) 2019-12, “Simplifying the Accounting for Income Taxes,” which removes
certain exceptions to the general principles of the accounting for income taxes and also improves consistent application of and simplification of other areas
when accounting for income taxes. The Company adopted this guidance as of January 1, 2021 and the guidance did not have an impact on its consolidated
financial statements.

39

 
 
 
 
 
 
 
 
 
Concentration of Credit Risk

The  Company  deposits  its  cash  in  financial  institutions.  At  times,  such  deposits  may  be  in  excess  of  insured  limits.  To  date,  the  Company  has  not
experienced any impairment losses on its cash. The Company also limits its credit risk with respect to accounts receivable by performing credit evaluations
when deemed necessary.

Cash and Cash Equivalents

The  Company  considers  all  highly  liquid  money  market  instruments  with  an  original  maturity  of  three  months  or  less  when  purchased  to  be  cash
equivalents.  At  December  31,  2021  and  2020,  cash  and  cash  equivalents  were  deposited  in  financial  institutions  and  consisted  entirely  of  immediately
available fund balances. The Company maintains its cash deposits and cash equivalents with financial institutions it believes to be well-known and stable.

Accounts Receivable

The Company provides credit terms to customers in connection with purchases of the Company’s products. Management periodically reviews customer
account activity in order to assess the adequacy of the allowances provided for potential collection issues and returns. Factors considered include economic
conditions, each customer’s payment and return history and credit worthiness. Adjustments, if any, are made to reserve balances following the completion
of these reviews to reflect management’s best estimate of potential losses. The allowance for doubtful accounts was approximately $1,000 and $11,000 as
of December 31, 2021 and 2020, respectively.

Inventory

For all medical device products and some commercial products, the Company engages third parties to manufacture and package its finished goods, which
are  shipped  to  the  Company  for  warehousing,  until  sold  to  distributors  or  end  customers.  Some  commercial  products  are  manufactured  at  Company
facilities.  Inventory  consists  of  finished  goods  and  raw  materials  and  is  valued  at  the  lower  of  cost  or  net  realizable  value  using  the  first-in,  first-out
method.

Our inventory reserve requirements are based on various factors including product expiration date and estimates for the future sales of the product. Reserve
assessments include inventory obsolescence based upon expiration date, damaged, or rejected product, slow-moving products, and other considerations.

License and Supply Rights

The  Company’s  rights  under  the  License  and  Supply  Agreement  with  Medica  are  capitalized  and  stated  at  cost,  less  accumulated  amortization,  and  are
amortized using the straight-line method over the term of the License and Supply Agreement, which is from April 23, 2012 through December 31, 2025.
The Company determines amortization periods for licenses based on its assessment of various factors impacting estimated useful lives and cash flows of
the  acquired  rights.  Such  factors  include  the  expected  launch  date  of  the  product,  the  strength  of  the  intellectual  property  protection  of  the  product  and
various  other  competitive,  developmental,  and  regulatory  issues,  and  contractual  terms.  See  Note  9  –  License  and  Supply  Agreement,  net  for  further
discussion.

Leases

The Company determines if an arrangement contains a lease at inception. Leases are included in lease right-of-use (“ROU”) assets and lease liabilities on
the consolidated balance sheet.

Lease  ROU  assets  and  lease  liabilities  are  recognized  based  on  the  present  value  of  the  future  minimum  lease  payments  over  the  lease  term  at
commencement  date.  As  most  of  the  Company’s  leases  do  not  provide  an  implicit  rate,  the  Company  uses  its  incremental  borrowing  rate  based  on  the
information  available  at  commencement  date  in  determining  the  present  value  of  future  payments.  The  operating  lease  ROU  asset  includes  any  lease
payments made and initial direct costs incurred and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the
lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line
basis over the lease term.

The Company has elected as an accounting policy not to apply the recognition requirements in ASC 842 to short-term leases. Short-term leases are leases
that have a term of 12 months or less and do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. The
Company recognizes the lease payments for short-term leases on a straight-line basis over the lease term.

The Company has also elected, as a practical expedient, by underlying class of asset, not to separate lease components from nonlease components and,
instead, account for them as a single component.

Property and Equipment, net

Property and equipment, net is stated at cost less accumulated depreciation. These assets are depreciated over their estimated useful lives of three to seven
years using the straight-line method.

The  Company  adheres  to  ASC  360  and  periodically  evaluates  whether  current  facts  or  circumstances  indicate  that  the  carrying  value  of  its  depreciable
assets to be held and used may not be recoverable. If such circumstances are determined to exist, an estimate of undiscounted future cash flows produced
by the long-lived assets, or the appropriate grouping of assets, is compared to the carrying value to determine whether impairment exists. If an asset is
determined to be impaired, the loss is measured based on the difference between the asset’s fair value and its carrying value. For long-lived assets, the
estimate of fair value is based on various valuation techniques, including a discounted value of estimated future cash flows. The Company reports an asset
to be disposed of at the lower of its carrying value or its fair value less costs to sell. There were no impairment losses for long-lived assets recorded for the
years ended December 31, 2021 and 2020.

41

 
 
 
 
 
 
 
 
 
 
 
 
Intangible Assets

The Company’s intangible assets include finite lived assets. Finite lived intangible assets, consisting of customer relationships, tradenames, service marks
and domain names are amortized on a straight-line basis over the estimated useful lives of the assets.

Finite lived intangible assets are tested for impairment when events or changes in circumstances indicate that the carrying value of the asset may not be
recoverable. Impairment testing requires management to estimate the future undiscounted cash flows of an intangible asset using assumptions believed to
be reasonable, but which are unpredictable and inherently uncertain. Actual future cash flows may differ from the estimates used in the impairment testing.

Goodwill

Goodwill represents the excess of purchase price over the fair value of net assets acquired. In accordance with ASC 350, “Goodwill and Other Intangibles,”
rather than recording periodic amortization, goodwill is subject to an annual assessment for impairment by applying a fair value-based test. If the fair value
of the reporting unit exceeds the reporting unit’s carrying value, including goodwill, then goodwill is considered not impaired, making further analysis not
required. The Company reviews goodwill for possible impairment annually during the fourth quarter, or whenever events or circumstances indicate that the
carrying amount may not be recoverable.

Fair Value Measurements

The Company measures certain financial instruments and other items at fair value.

To determine the fair value, the Company uses the fair value hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs
and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market
participants would use to value an asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are
inputs based on assumptions about the factors market participants would use to value an asset or liability.

To measure fair value, the Company uses the following fair value hierarchy based on three levels of inputs, of which the first two are considered observable
and the last unobservable:

Level 1 - Quoted prices in active markets for identical assets or liabilities.

Level 2 - Inputs other than Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets and
liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can
be corroborated by observable market data by correlation or other means.

Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Value is
determined using pricing models, discounted cash flow methodologies, or similar techniques and also includes instruments for which the determination of
fair value requires significant judgment or estimation.

Revenue Recognition

The  Company  recognizes  revenue  under  ASC  606,  “Revenue  from  Contracts  with  Customers.”  ASC  606  prescribes  a  five-step  model  for  recognizing
revenue,  which  includes  (i)  identifying  contracts  with  customers;  (ii)  identifying  performance  obligations;  (iii)  determining  the  transaction  price;  (iv)
allocating the transaction price; and (v) recognizing revenue. See Note 4 – Revenue Recognition for further discussion.

42

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Shipping and Handling Costs

Shipping and handling costs charged to customers are recorded as revenue and as cost of goods sold and were approximately $71,000 and $47,000 for the
years ended December 31, 2021 and 2020, respectively.

Research and Development Costs

Research  and  development  costs  represent  a  significant  part  of  our  business.  Costs  included  in  research  and  development  are  expensed  as  incurred  and
relate to the processes of discovering, testing and developing new products, improving existing products and regulatory compliance prior to FDA approval.
Research and development costs include, but are not limited to, personnel expenses, consulting costs and equipment depreciation.

Stock-Based Compensation

The  fair  value  of  stock  options  is  recognized  as  stock-based  compensation  expense  in  the  Company’s  consolidated  statement  of  operations  and
comprehensive  loss.  The  Company  calculates  stock-based  compensation  expense  in  accordance  with  ASC  718.  The  fair  value  of  the  Company’s  stock
option awards is estimated using a Black-Scholes option valuation model. This model requires the input of highly subjective assumptions and elections
including expected stock price volatility and the estimated life of each award. The fair value of stock-based awards is amortized over the vesting period of
the award. For stock awards that vest based on performance conditions (e.g., achievement of certain milestones), expense is recognized when it is probable
that the condition will be met.

Warrants

The Company accounts for stock warrants as either equity instruments or derivative liabilities depending on the specific terms of the warrant agreement.

Other Income and Expense, net

Other  income,  net,  of  $0.5  million  for  the  year  ended  December  31,  2021  is  primarily  due  to  the  extinguishment  of  the  U.S.  Small  Business
Administration’s Paycheck Protection Plan (“PPP”) loan. Other expense, net, of $0.2 million  for  the  year  ended  December  31,  2020  is  primarily  due  to
interest expense of $0.1 million and $0.1 million of foreign currency transaction losses.

Income Taxes

The Company accounts for income taxes in accordance with ASC 740, which requires accounting for deferred income taxes under the asset and liability
method.  Deferred  income  taxes  are  recognized  for  the  tax  consequences  of  temporary  differences  by  applying  enacted  statutory  tax  rates  applicable  in
future years to differences between the financial statement carrying amounts and the tax basis of existing assets and liabilities.

For financial reporting purposes, the Company has incurred a loss in each period since its inception. Based on available objective evidence, including the
Company’s history of losses, management believes it is more likely than not that the net deferred tax assets will not be fully realizable. Accordingly, the
Company provided for a full valuation allowance against its net deferred tax assets at December 31, 2021 and 2020.

ASC 740 prescribes, among other things, a recognition threshold and measurement attributes for the financial statement recognition and measurement of
uncertain tax positions taken or expected to be taken in a company’s income tax return. ASC 740 utilizes a two-step approach for evaluating uncertain tax
positions. Step one, or recognition, requires a company to determine if the weight of available evidence indicates a tax position is more likely than not to be
sustained upon audit, including resolution of related appeals or litigation processes, if any. Step two, or measurement, is based on the largest amount of
benefit that is more likely than not to be realized on settlement with the taxing authority. The Company is subject to income tax examinations by major
taxing authorities for all tax years subsequent to 2016. During the years ended December 31, 2021 and 2020, the Company recognized no adjustments for
uncertain tax positions. However, management’s conclusions regarding this policy may be subject to review and adjustment at a later date based on factors
including, but not limited to, on-going analyses of and changes to tax laws, regulation and interpretations, thereof.

The Coronavirus Aid, Relief, and Economic Security Act (the CARES Act) was enacted into law on March 27, 2020. The act contains several tax relief and
economic stimulus provisions. The enactment of the CARES Act did not have a material impact on the Company’s financial statements.

See Note 15 – Income Taxes for further discussion.

Net Loss per Common Share

Basic net loss per common share is calculated by dividing net loss available to common stockholders by the number of weighted average common shares
issued and outstanding. Diluted net loss per common share is calculated by dividing net loss available to common stockholders by the weighted average
number  of  common  shares  issued  and  outstanding  for  the  period,  plus  amounts  representing  the  dilutive  effect  from  the  exercise  of  stock  options  and
warrants, as applicable. The Company calculates dilutive potential common shares using the treasury stock method, which assumes the Company will use
the proceeds from the exercise of stock options and warrants to repurchase shares of common stock to hold in its treasury stock reserves.

The following securities have been excluded from the dilutive per share computation as they are antidilutive:

Shares underlying options outstanding
Shares underlying warrants outstanding
Unvested restricted stock

Foreign currency translation is recognized in accordance with ASC 830. The functional currency of Nephros International Limited, the Company’s Irish
subsidiary is the Euro, and its translation gains and losses are included in accumulated other comprehensive income. The balance sheet is translated at the
year-end rate. The consolidated statements of operations and comprehensive loss are translated at the weighted average rate for the year.

Comprehensive Loss

Comprehensive  loss,  as  defined  in  ASC  220,  is  the  total  of  net  loss  and  all  other  non-owner  changes  in  equity  (or  other  comprehensive  loss).  The
Company’s other comprehensive loss consists only of foreign currency translation adjustments.

Recent Accounting Pronouncements, Not Yet Effective

In May 2021, the FASB issued ASU 2021-04, “Issuer’s Accounting for Certain Modifications or Exchanges of Freestanding Equity-Classified Written Call
Options,”  which  clarifies  and  reduces  diversity  in  an  issuer’s  accounting  for  modifications  or  exchanges  of  freestanding  equity-classified  written  call
options that remain equity classified after modification or exchange. The guidance is effective for the Company beginning in the first quarter of fiscal year
2022. Early adoption is permitted. The Company is assessing the impact of adopting this guidance on its consolidated financial statements.

In  October  2021,  the  FASB  issued  ASU  2021-08,  “Accounting  for  Contract  Assets  and  Contract  Liabilities  from  Contracts  with  Customers,”  which
requires  that  an  entity  recognize  contract  assets  and  contract  liabilities  acquired  in  a  business  combination  in  accordance  with  Accounting  Standards
Codification (“ASC”) 606. The guidance is effective for the Company beginning in the first quarter of fiscal year 2023 and should be applied prospectively.
Early adoption is permitted. The Company will assess the impact, if any, of adopting this guidance on its consolidated financial statements.

Note 3 – Asset Acquisition

On July 9, 2021, the Company acquired 100% of GenArraytion, Inc. (“GenArraytion”). The acquisition did not qualify as a business combination and, as a
result, was accounted for as an asset acquisition as the fair value of the gross assets acquired was primarily related to a single asset. The Company issued
123,981 shares of the Company’s common stock to GenArraytion, reflecting an aggregate purchase price of $1.2 million. The purchase price, including
direct acquisition costs of approximately $49,000, was allocated among the acquired assets which include intellectual property and equipment, based upon
their relative fair values at the date of acquisition.

Fifty percent of the 123,981 common shares issued were subject to a risk of forfeiture which lapsed during the three months ended September 30, 2021.
The Company will also make royalty payments to GenArraytion equal to 5% of net sales of certain products over the next five years. Net revenues related
to GenArraytion customers were not significant during the year ended December 31, 2021.

The total consideration of $1.2 million was allocated as follows to the acquired assets:

Intellectual property
Equipment

The acquired intellectual property is being amortized over its estimated useful life of 10 years (see Note 8 – Intangible Assets and Goodwill).

Note 4 – Revenue Recognition

The Company recognizes revenue related to product sales when product is shipped via external logistics provider and the other criteria of ASC 606 are met.
Product revenue is recorded net of returns and allowances. There was no allowance for sales returns at December 31, 2021 or 2020. In addition to product
revenue, the Company recognizes revenue related to royalty and other agreements in accordance with the five-step model in ASC 606. Royalty and other
revenues recognized for the years ended December 31, 2021 and 2020 (in thousands) is comprised of:

Other revenue
Royalty revenue under the License Agreement with Bellco

In  May  2015,  the  Company  entered  into  a  Sublicense  Agreement  (the  “Sublicense  Agreement”)  with  CamelBak  Products,  LLC
(“CamelBak”).  Under  the  Sublicense  Agreement,  the  Company  granted  CamelBak  an  exclusive,  non-transferable,  worldwide  (with  the
exception of Italy) sublicense and license, in each case solely to market, sell, distribute, import and export the Company’s individual water
treatment  device.  In  exchange  for  the  rights  granted  to  CamelBak,  CamelBak  agreed,  through  December  31,  2022,  to  pay  the  Company  a
percentage of the gross profit on any sales made to a branch of the U.S. military, subject to certain exceptions, and to pay a fixed per-unit fee
for any other sales made. CamelBak was also required to meet or exceed certain minimum annual fees payable to the Company, and if such
fees were not met or exceeded, the Company was able to convert the exclusive sublicense to a non-exclusive sublicense with respect to non-
U.S. military sales. In the first quarter of 2019, the Sublicense Agreement was amended to eliminate the minimum fee obligations starting
May 6, 2018 and, as such, Camelbak has no further minimum fee obligation.

Bellco License Agreement

With regard to the OLpūr MD190 and MD220, on June 27, 2011, the Company entered into a License Agreement (the “License Agreement”), effective
July 1, 2011, with Bellco S.r.l. (“Bellco”), an Italy-based supplier of hemodialysis and intensive care products, for the manufacturing, marketing and sale of
the Company’s patented mid-dilution dialysis filters (the “Products”). Under the License Agreement, as amended, the Company granted Bellco a license to
manufacture, market and sell the Products under its own name, label, and CE mark in certain countries on an exclusive basis, and to do the same on a non-
exclusive  basis  in  certain  other  countries.  Under  the  License  Agreement  with  Bellco,  the  Company  received  upfront  payments  which  were  previously

2021, Bellco committed to pay the Company a royalty based on the number of units of Products sold per year in the covered territory as follows: for the
first  125,000  units  sold  in  total,  €1.75  (approximately  $2.10)  per  unit;  thereafter,  €1.25  (approximately  $1.50)  per  unit.  The  License  Agreement  also
provided for a fixed royalty payment payable to the Company for the period beginning on January 1, 2015 through and including December 31, 2021 if the

For the year ended December 31, 2020 the change in fair value of contingent consideration of $0.2 million was due to the settlement of the contingent
consideration liability. In October 2020, the Company entered into a Second Amendment to the Membership Interest Purchase Agreement dated December
31, 2018 related to the acquisition of the Aether business, in which the Company agreed to pay a lump sum of $0.1 million in full consideration for the
Company’s obligation to make payments of contingent consideration under the Membership Interest Purchase Agreement. Approximately $94,000 of the
remaining obligation as a result of the lump sum settlement was paid out of amounts remaining in escrow.

Consideration paid in a business combination may include potential future payments that are contingent upon the acquired business achieving certain levels
of  earnings  in  the  future  (“contingent  consideration”).  Contingent  consideration  liabilities  are  measured  at  their  estimated  fair  value  as  of  the  date  of
acquisition, with subsequent changes in fair value recorded in the consolidated statements of operations. Fair value as of the date of acquisition is estimated
based  on  projections  of  expected  future  cash  flows  of  the  acquired  business.  The  Company  estimated  the  contingent  consideration  liability  using  the
income  approach  (discounted  cash  flow  method),  which  requires  the  Company  to  make  estimates  and  assumptions  regarding  the  future  cash  flows  and
profits. Changes in these estimates and assumptions could have a significant impact on the amounts recognized.

There were no transfers between levels in the fair value hierarchy during the year ended December 31, 2021.

Assets and Liabilities Not Measured at Fair Value on a Recurring Basis

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value as of December 31,
2021 and 2020 due to the short-term maturity of these instruments.

The carrying amounts of the secured long-term note payable, lease liabilities and equipment financing approximate fair value as of December 31, 2021 and
2020  because  those  financial  instruments  bear  interest  at  rates  that  approximate  current  market  rates  for  similar  agreements  with  similar  maturities  and
credit.

The carrying amount of the U.S. Small Business Administration’s Paycheck Protection Program (“PPP”) loan outstanding at December 31, 2020 did not
include interest imputed at a market rate as the PPP loan was a transaction whereby the interest rate was prescribed by a government agency.

Note 9 – License and Supply Agreement, net

On April 23, 2012, the Company entered into a License and Supply Agreement (as thereafter amended, the “License and Supply Agreement”) with Medica
S.p.A. (“Medica”), an Italy-based medical product manufacturing company, for the marketing and sale of certain filtration products based upon Medica’s
proprietary Medisulfone ultrafiltration technology in conjunction with the Company’s filtration products, and for an exclusive supply arrangement for the
filtration products. Under the License and Supply Agreement Medica granted to the Company an exclusive license, with right of sublicense, to market,
promote, distribute, offer for sale and sell the filtration products worldwide, with certain limitations on territory, during the term of the License and Supply
Agreement. In addition, the Company granted to Medica an exclusive license under the Company’s intellectual property to make the filtration products
during  the  term  of  the  License  and  Supply  Agreement.  The  filtration  products  covered  under  the  License  and  Supply  Agreement  include  both  certain
products  based  on  Medica’s  proprietary  Versatile  microfiber  technology  and  certain  filtration  products  based  on  Medica’s  proprietary  Medisulfone
ultrafiltration  technology.  The  term  of  the  License  Agreement  with  Medica  expires  on  December  31,  2025,  unless  earlier  terminated  by  either  party  in
accordance with the terms of the License and Supply Agreement.

In exchange for the license, the gross value of the intangible asset capitalized was $2.3 million. License and supply agreement, net, on the consolidated
balance sheet is $0.5 million and $0.7 million as of December 31, 2021 and 2020, respectively. Accumulated amortization is $1.8 million and $1.6 million

In addition, for the period beginning April 23, 2014 through December 31, 2025, the Company will pay Medica a royalty rate of 3% of net sales of the
filtration  products  sold,  subject  to  reduction  as  a  result  of  a  supply  interruption  pursuant  to  the  terms  of  the  License  and  Supply  Agreement.  Royalty
expense of $0.3 million and $0.2 million for the year ended December 31, 2021 and 2020, respectively, was recognized and is included in cost of goods

working capital and general corporate purposes.

On May 26, 2020, the Company terminated the Revolver and, as a result, recognized fees of approximately $7,000, which are included in interest expense
on the consolidated statement of operations and comprehensive loss for the year ended December 31, 2020. Although the Revolver was terminated, the

Note (see Note 11 – Secured Note Payable).

For the year ended December 31, 2020, excluding approximately $7,000 related to the termination of the Revolver, approximately $25,000 was recognized
as interest expense on the consolidated statement of operations and comprehensive loss.

Note 11 – Secured Note Payable

On March 27, 2018, the Company entered into a Secured Promissory Note Agreement (the “Secured Note”) with Tech Capital for a principal amount of
$1.2 million. The Secured Note was amended and restated on May 26, 2020 to reflect the then-current balance on the Secured Note. There were no other
changes to the terms and conditions of the Secured Note. As of December 31, 2021 and 2020, the principal balance of the Secured Note was $0.3 million
and $0.6 million, respectively.

A  valuation  allowance  has  been  recognized  to  offset  the  Company’s  net  deferred  tax  asset  as  it  is  more  likely  than  not  that  such  net  asset  will  not  be
realized. The Company primarily considered its historical loss and potential Internal Revenue Code Section 382 limitations to arrive at its conclusion that a
valuation allowance was required. The Company’s valuation allowance increased approximately $691,000 from December 31, 2020 to December 31, 2021.

At December 31, 2021, the Company had Federal income tax net operating loss carryforwards of $81.8 million and State income tax net operating loss
carryforwards of $4.9 million. Foreign income tax net operating loss carryforwards were $7.6 million as of December 31, 2021. The Company had Federal
research  and  development  tax  credit  carryforwards  of  $1.4 million  at  December  31,  2021.  State  research  and  development  tax  credit  carryforwards  of
approximately $7,000 at December 31, 2021. The Company’s net operating losses and research and development tax credits may ultimately be limited by
Section  382  of  the  Internal  Revenue  Code  and,  as  a  result,  the  Company  may  be  unable  to  offset  future  taxable  income  (if  any)  with  losses,  or  its  tax
liability with credits, before such losses and credits expire. Included in the Federal net operating loss carryforwards are $13.0 million of losses generated
from 2018 onward that have an indefinite carryover period. The remaining Federal and New Jersey net operating loss carryforwards and Federal and New
Jersey tax credit carryforwards will expire at various times between 2021 and 2038 unless utilized.

The  Company  has  analyzed  the  tax  positions  taken  or  expected  to  be  taken  in  its  tax  returns  and  concluded  it  has  no  liability  related  to  uncertain  tax
positions. The Company is subject to income tax examinations by major taxing authorities for all tax years subsequent to 2016 and does not anticipate a
change in its uncertain tax positions within the next twelve months. The Company’s policy is to report interest and penalties, if any, related to unrecognized
tax benefits in income tax expense.

Note 16 - Stock Plans and Share-Based Payments

The  fair  value  of  stock  options  and  restricted  stock  is  recognized  as  stock-based  compensation  expense  in  the  Company’s  consolidated  statement  of
operations  and  comprehensive  loss.  The  Company  calculates  stock-based  compensation  expense  in  accordance  with  ASC  718.  The  fair  value  of  stock-
based awards is amortized over the vesting period of the award.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model with the below assumptions for the risk-
free interest rates, expected dividend yield, expected lives and expected stock price volatility.

Expected volatility is based on historical volatility of the Company’s common stock at the time of grant. The risk-free interest rate is based on the U.S.
Treasury yields in effect at the time of grant for periods corresponding with the expected life of the options. For the expected life, the Company is using the
simplified method as described in the SEC Staff Accounting Bulletin 107. This method assumes that stock option grants will be exercised based on the
average of the vesting periods and the option’s life.

The  weighted-average  fair  value  of  options  granted  in  2021  and  2020  is  $4.94 and $4.45,  respectively.  The  aggregate  intrinsic  values  of  stock  options
outstanding and stock options vested or expected to vest as of December 31, 2021 were $0.7 million and $0.8 million,  respectively.  A  stock  option  has
intrinsic value, at any given time, if and to the extent that the exercise price of such stock option is less than the market price of the underlying common
stock at such time. The weighted-average remaining contractual life of options vested or expected to vest as of December 31, 2021 was 6.6 years.

The intrinsic values of stock options exercised were approximately $265,000 and $20,000 for the years ended December 31, 2021 and 2020.

As of December 31, 2021, there was $2.4 million of total unrecognized compensation cost related to unvested share-based compensation awards granted
under the equity compensation plans which will be amortized over the weighted average remaining requisite service period of 3.0 years.

Restricted Stock

The Company has issued restricted stock as compensation for the services of certain employees and non-employee directors. The grant date fair value of
restricted stock is based on the fair value of the common stock on the date of grant, and compensation expense is recognized based on the period in which
the restrictions lapse.

The total fair value of restricted stock that vested during the years ended December 31, 2021 and 2020 was $0.2 million and $0.5 million, respectively.

Total stock-based compensation expense for the restricted stock granted to employees and non-employee directors was approximately $333,000 for the year
ended December 31, 2021 and is included in selling, general and administrative expenses on the accompanying consolidated statement of operations and
comprehensive loss. Total stock-based compensation expense for the restricted stock granted to employees and non-employee directors was approximately
$52,000  for  the  year  ended  December  31,  2020.  Approximately  $42,000  and  $10,000  is  included  in  selling,  general  and  administrative  expenses  and
research and development expenses, respectively, on the accompanying consolidated statement of operations and comprehensive loss for the year ended
December 31, 2020. Approximately $169,000 of restricted stock was granted to employees during the year ended December 31, 2021 for services rendered
during the year ended December 31, 2020.

As of December 31, 2021, there was approximately $172,000 of unrecognized compensation expense related to the restricted stock awards which will be
amortized over the weighted average remaining requisite service period of 2.5 years.

The  aggregate  shares  of  common  stock  legally  issued  and  outstanding  as  of  December  31,  2021  is  greater  than  the  aggregate  shares  of  common  stock
outstanding for accounting purposes by the amount of unvested restricted shares.

SRP Equity Incentive Plan

SRP’s 2019 Equity Incentive Plan was approved on May 7, 2019 under which 150,000 shares of SRP’s common stock are reserved for the issuance of
options and other awards. There were no SRP stock options granted during the year ended December 31, 2021. SRP stock options are being expensed over
the respective vesting period, which is based on a service condition.

Note 17 - Stockholders’ Equity

July 2021 Common Stock Issuance

On July 9, 2021, the Company issued 123,981 shares of common stock to acquire 100% of GenArraytion. The purchase price was $1.2 million, including
transaction costs of approximately $49,000, and was allocated among the acquired assets based upon their relative fair values at the date of acquisition.
Fifty percent of the 123,981 common shares issued were subject to a risk of forfeiture which lapsed during the three months ended September 30, 2021.

October 2020 Common Stock Issuance

On October 20, 2020, the Company issued 833,333 shares of the Company’s common stock in a registered direct offering, resulting in gross proceeds to the
Company of $5.0 million. The purchase price for each share was $6.00. Proceeds, net of equity issuance costs of $0.3 million, recorded as a result of the
offering were $4.7 million. Of the 833,333 shares of the Company’s common stock issued, 166,667 shares, resulting in proceeds of $1.0 million, were sold
to the Company’s largest stockholder.

February 2020 Common Stock Issuance

On February 4, 2020, the Company issued 937,500 shares of common stock through a confidentially marketed underwritten public offering resulting in
gross  proceeds  to  the  Company  of  $7.5  million.  The  purchase  price  for  each  share  was  $8.00.  Proceeds,  net  of  equity  issuance  costs  of  $0.7  million,
recorded as a result of the offering were $6.8 million.

Noncontrolling Interest

On  September  5,  2018,  SRP  entered  into  a  Series  A  Preferred  Stock  Purchase  Agreement  with  certain  purchasers  pursuant  to  which  SRP  sold  600,000
shares of its Series A Preferred Stock (“Series A Preferred”) for $5.00 per share. The aggregate purchase price was $3.0 million. The net proceeds from the
issuance of the Series A Preferred are restricted to SRP expenses, and may not be used for the benefit of the Company or other affiliated entities, except to
reimburse for expenses directly attributable to SRP. Following the Series A Preferred transaction, the Company retained a 62.5% ownership interest in SRP,
holding 100% of the outstanding common shares, and holders of Series A Preferred retained a 37.5% interest in SRP on a fully diluted basis, holding 100%
of  the  outstanding  preferred  shares.  Of  the  600,000 shares  of  Series  A  Preferred  issued,  the  shares  purchased  by  related  parties  comprised  of  persons
controlled by members of management and by the Company’s largest stockholder amounted to 18,000 and 400,000 shares, respectively.

Each share of Series A Preferred is initially convertible into one share of SRP common stock, subject to adjustment for stock splits and recapitalization
events. Subject to customary exempt issuances, in the event SRP issues additional shares of its common stock or securities convertible into common stock
at a per share price that is less than the original Series A Preferred price, the conversion price of the Series A Preferred will automatically be reduced to
such lower price.

In the event of any voluntary or involuntary liquidation, dissolution or winding up of SRP, the holders of the Series A Preferred are entitled to be paid out
of  the  assets  of  SRP  available  for  distribution  to  its  stockholders  or,  in  the  case  of  a  deemed  liquidation  event,  out  of  the  consideration  payable  to
stockholders in such deemed liquidation event or the available proceeds, before any payment shall be made to the holders of SRP common stock by reason
of their ownership thereof, an amount per share equal to one times (1x) the Series A Preferred original issue price, plus any accruing dividends accrued but
unpaid thereon, whether or not declared, together with any other dividends declared but unpaid thereon (the “Series A Liquidation Preference”). If upon
any such liquidation, dissolution or winding up of SRP or deemed liquidation event, the assets of SRP available for distribution to its stockholders shall be
insufficient to pay the Series A Liquidation Preference in full, the holders of Series A Preferred shall share ratably in any distribution of the assets available
for distribution in proportion to the respective amounts which would otherwise be payable in respect of the shares held by them upon such distribution if all
amounts payable on or with respect to such shares were paid in full. After the full payment of the Series A Liquidation Preference, the holders of the Series
A Preferred and the holders of common stock will share ratably in any remaining proceeds available for distribution on an as-converted to common stock
basis.

58

 
 
 
 
 
 
 
 
 
 
 
 
 
 
Each share of Series A Preferred accrues dividends at the rate per annum of $0.40 per share. The accruing dividends shall accrue from day to day, whether
or not declared, and shall be cumulative and shall be payable only when, as, and if declared by the Board. As of December 31, 2021, accrued dividends on
the Series A Preferred was $0.8 million.

Holders of Series A Preferred shall be entitled to cast the number of votes equal to the number of whole shares of common stock into which the shares of
Series A Preferred held by such holder are convertible as of the record date for determining stockholders entitled to vote. Except as provided by law or by
the other provisions, the holders of Series A Preferred vote together with the holders of common stock as a single class. Notwithstanding the foregoing, for
as long as at least 150,000 shares of Series A Preferred are outstanding, SRP is required to obtain the affirmative vote or written consent of a majority of
the Series A Preferred in order to effect certain corporate transactions, including without limitation, the issuance of any securities senior to or on parity with
the  Series  A  Preferred,  a  liquidation  or  deemed  liquidation  of  SRP,  amendments  to  SRP’s  charter  documents,  the  issuance  of  indebtedness  in  excess  of
$250,000, any annual budget for the Company’s operations, and the hiring or firing of any executive officers of SRP. In addition, the holders of the Series
A Preferred are entitled to elect two members of SRP’s board of directors.

The noncontrolling interest in SRP held by holders of the Series A Preferred has been classified as equity on the accompanying consolidated balance sheet,
as the noncontrolling interest is redeemable only upon the occurrence of events that are within the control of the Company.

Warrants

The Company accounts for stock warrants as either equity instruments or derivative liabilities depending on the specific terms of the warrant agreement. As
of December 31, 2021 and 2020, all of the Company’s outstanding warrants are classified as equity.

$33,000.

Note 18 – Savings Incentive Match Plan

On January 1, 2017, the Company established a Savings Incentive Match Plan for Employees Individual Retirement Account (SIMPLE IRA), which covers
all  employees.  The  SIMPLE  IRA  Plan  provides  for  voluntary  employee  contributions  up  to  statutory  IRA  limitations.  The  Company  matches  100%  of
employee contributions to the SIMPLE IRA Plan, up to 3% of each employee’s salary. The Company contributed and expensed approximately $92,000 and
$89,000 to the SIMPLE IRA in 2021 and 2020, respectively.

Note 19 - Commitments and Contingencies

Purchase Commitments

In exchange for the rights granted under the License and Supply Agreement with Medica (see Note 9 – License and Supply Agreement, net), the Company
agreed  to  make  certain  minimum  annual  aggregate  purchases  from  Medica  over  the  term  of  the  License  and  Supply  Agreement.  For  the  year  ended
December 31, 2021, the Company agreed to make minimum annual aggregate purchases from Medica of €3.3 million (approximately $3.9 million). For the
year ended December 31, 2021, the Company’s aggregate purchase commitments totaled €3.5 million (approximately $4.2 million).

Note 20 – Segment Reporting

The Company has defined three  reportable  segments:  Water  Filtration,  Pathogen  Detection  and  Renal  Products.  The  Water  Filtration  segment  primarily
develops and sells high performance water purification filters. The Pathogen Detection segment develops and sells portable, real-time water testing systems
designed to provide actionable data on waterborne pathogens in approximately one hour. The Renal Products segment is focused on the development of
medical device products for patients with renal disease, including a 2nd generation hemodiafiltration system for the treatment of patients with ESRD.

The  Company’s  chief  operating  decision  maker  evaluates  the  financial  performance  of  the  Company’s  segments  based  upon  segment  revenues,  gross
margin and operating expenses which include research and development and selling, general and administrative expenses. Items below loss from operations
are not reported by segment, since they are excluded from the measure of segment profitability reviewed by the Company’s chief operating decision maker.
The Company does not report balance sheet information by segment since such information is not reviewed by the Company’s chief operating decision
maker.

The  accounting  policies  for  the  Company’s  segments  are  the  same  as  those  described  in  Item  7,  “Management’s  Discussion  and  Analysis  of  Financial
Condition  and  Results  of  Operations  –  Critical  Accounting  Policies  and  Estimates”  of  this  Annual  Report  on  Form  10-K  and  Note  2  –  Summary  of

As of December 31, 2021, $0.2 million of total assets in the Renal Products segment consisted of cash received from the loan agreement between Nephros
and SRP.

As of December 31, 2020, $0.2 million of total assets were in the Renal Products segment. The $0.2 million consisted of $0.1 million of remaining cash
received from the sale of Series A Preferred during the year ended December 31, 2018 and prepaid expenses and other current assets of $0.1 million.

Note 21 – Subsequent Event

On February 1, 2022, SRP, the Company’s majority-owned subsidiary, entered into a First Amendment to Series A Preferred Stock Purchase Agreement
(the  “Amendment”)  with  the  holders  of  SRP’s  outstanding  shares  of  Series  A  Preferred  Stock.  The  Amendment  amended  the  terms  of  the  Series  A
Preferred  Stock  Purchase  Agreement,  dated  September  9,  2018,  among  SRP  and  the  purchasers  identified  therein  (the  “SRP  Purchase  Agreement”),
pursuant to which SRP had sold to such purchasers an aggregate of 600,000 shares of its Series A Preferred Stock at a price of $5.00 per share resulting in
total gross proceeds of $3.0 million. The purpose of the Amendment was to permit SRP to sell up to an additional 100,003 shares of its Series A Preferred
Stock at one or more closings to occur by February 28, 2022, and on the same terms and conditions as otherwise set forth in the SRP Purchase Agreement.
Pursuant to the Amendment, on February 4, 2022, SRP conducted a closing in which it sold 100,003 shares of Series A Preferred Stock, resulting in gross
proceeds of $500,015. The Company purchased 62,500  shares  of  SRP’s  Series  A  Preferred  at  such  closing  and,  as  a  result,  maintained  its  62.5%  stock
ownership  position  in  SRP.  The  other  purchasers  at  the  February  4,  2022  closing  included  the  Company’s  Chief  Executive  Officer,  who  purchased  833
shares, and Lambda Investors LLC (“Lambda”), an affiliate of Wexford Capital, which beneficially owns approximately 36% of the Company’s common
stock, which purchased 29,938 shares of SRP Series A Preferred Stock. Such purchases were made on the same terms as all other purchasers.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure

There were no disagreements with the accountants during 2021 or 2020.

Item 9A. Controls and Procedures

Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures that are designed to ensure that information required to be disclosed in the reports
filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms.
Disclosure  controls  and  procedures  include,  without  limitation,  controls  and  procedures  designed  to  ensure  that  information  required  to  be  disclosed  in
company reports filed or submitted under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and
Chief Financial Officer, to allow timely decisions regarding required disclosure.

As required by Rules 13a-15 and 15d-15 under the Exchange Act, the Chief Executive Officer and Chief Financial Officer carried out an evaluation of the
effectiveness  of  the  design  and  operation  of  the  disclosure  controls  and  procedures  as  of  December  31,  2021.  Based  upon  this  evaluation,  the  Chief
Executive  Officer  and  Chief  Financial  Officer  has  concluded  that  the  disclosure  controls  and  procedures  were  effective  as  of  December  31,  2021.
Accordingly, management believes that the financial statements included in this Annual Report on Form 10-K present fairly in all material respects the
financial position, results of operations and cash flows for the period presented.

Management’s Report on Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act
Rules 13a-15(f) and 15d-15(f). Under the supervision of the Chief Executive Officer and Chief Financial Officer, management conducted an evaluation of
the effectiveness of the internal control over financial reporting as of December 31, 2021 based on the framework set forth by the Committee of Sponsoring
Organizations of the Treadway Commission (COSO) in “Internal Control-Integrated Framework”. Based on the assessment, management concluded that as
of December 31, 2021, the internal control over financial reporting was effective as of December 31, 2021.

Changes in Internal Control Over Financial Reporting

There were no changes in the internal control over financial reporting that occurred during the most recent fiscal quarter that materially affected, or are
reasonably likely to materially affect, the internal control over financial reporting.

I, Andrew Astor, certify that:

(1) I have reviewed this Annual Report on Form 10-K of Nephros, Inc.;

statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this

(a) Designed  such  disclosure  controls  and  procedures,  or  caused  such  disclosure  controls  and  procedures  to  be  designed  under  our  supervision,  to

entities, particularly during the period in which this report is being prepared;

(b) Designed  such  internal  control  over  financial  reporting,  or  caused  such  internal  control  over  financial  reporting  to  be  designed  under  our

affect, the registrant’s internal control over financial reporting; and

(5) I  have  disclosed,  based  on  our  most  recent  evaluation  of  internal  control  over  financial  reporting,  to  the  registrant’s  auditors  and  the  audit

committee of the registrant’s board of directors (or persons performing the equivalent functions):

(a) All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably

likely to adversely affect the registrant’s ability to record, process, summarize and report financial information; and

(b) Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant’s internal control

over financial reporting.
