Item 1. Business

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.  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. Our products are marketed primarily to the food service, hospitality, convenience store, and health care markets. These commercial
products are also marketed into medical markets, as supplemental filtration to our medical filters.

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.

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.

3

 
 
 
 
 
 
 
 
 
 
 
 
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 with limited 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 have and will continue to facilitate
growth in filter sales outside of the medical industry.

In commercial markets, we develop and sell our filters, for which carbon-based absorption is the primary filtration mechanism. These 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.  These  commercial  products  are  also  sold  into  medical  markets,  as  supplemental  filtration  to  our
medical filters.

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 and Home/Portable Dialysis Machines: Filtration of water or bicarbonate concentrate used in hemodialysis.
● Commercial 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 2022, according to the American Hospital Association, there are approximately 6,100 hospitals in the U.S., with approximately 921,000 beds. Over
33 million patients were admitted to these hospitals. The U.S. Centers for Disease Control and Prevention (“CDC”) estimates that healthcare associated
infections (“HAI”) occur in approximately 1 out of every 31 hospital patients, which calculates to over one million patients in 2022. 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 January 2022, the Center for Clinical Standards and Quality at the Centers for Medicare and Medicaid Services (“CMS”) expanded its requirements –
originally implemented in 2017 – for facilities to develop policies and procedures that inhibit the growth and spread of legionella and other opportunistic
pathogens  in  building  water  systems.  In  this  2022  update,  CMS  requires  teams  to  be  assigned  to  the  development  of  formal  water  management  plans
(“WMPs”),  as  well  as  detailed  documentation  regarding  the  development  of  the  WMPs  and  their  execution.  CMS  surveyors  regularly  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
product 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.

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.

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.

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 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” configuration.

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,  our  commercial  filtration  offerings  include  technologies  that  are  primarily  focused  on
improving odor and taste and on reducing scale and heavy metals from filtered water.

Our commercial market focus is on the hotel, restaurant, and convenience store markets. In March 2022, we closed a contract to provide water filtration
systems to an organization of approximately 3,000 Quick Service Restaurants (“QSR”). We continue to pursue other national accounts, which 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 Nephros and Everpure® manifolds. Included in the NanoGuard product line are both conventional and flushable filters.

● The Nephros line of commercial filters provide a variety of technology solutions that improve water quality in food service, convenience store,
hospitality,  and  industrial  applications.  Nephros  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.

Nephros  commercial  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.

Pathogen Detection Systems

In 2019, we expanded our portfolio of water solutions with the introduction of pathogen detection system (“PDS”) products and services, including our
PluraPath pathogen detection system, which we developed to provide real-time data regarding the existence of a broad array of waterborne pathogens to the
infection control teams responsible executing a building or other facility’s water management plans. In the third quarter of 2021, we acquired the business
of GenArraytion, Inc. (“GenArraytion” ), including 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  was  integrated  into  our  PDS
segment. In November 2022, we sold substantially all of our assets used in our PDS business to BWSI, LLC pursuant to the terms of an Agreement for
Purchase and Sale of Assets with BWSI (the “PDS Purchase Agreement”). Under the terms of the PDS Purchase Agreement, BWSI made a nominal cash
payment  at  the  closing  of  the  transaction  and  assumed  certain  continuing  liabilities  of  the  PDS  business.  Additionally,  for  a  period  of  seven  years
commencing January 1, 2023, and ending December 31, 2029, BWSI will pay us an annual royalty equal to a specified percentage of gross margin received
by BWSI from each of the sale and licensing of products developed by the PDS Business.

Hemodiafiltration (HDF) Systems and Specialty Renal Products, Inc.

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.

Our company was originally founded to develop and commercialize a hemodiafiltration (“HDF”) medical device. 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 demonstrate that HDF’s
benefits, among other factors, include enhanced clearance of middle and large molecular weight toxins, improved patient survival, reduced incidence of
dialysis-related amyloidosis, improved patient quality of life and reduced hospitalizations and overall length of stays.

Our original HDF device

(“HDF1”) was cleared by the U.S. Food and Drug Administration (“FDA”) for the treatment of patients with chronic renal failure in 2012, but did not gain
market acceptance due to, among other reasons, the feeling that it was too difficult to use. Accordingly, since 2018, we have undertaken to redesign and
dramatically simplify our HDF device. We believe our updates have made the system significantly easier to use.

In  2018,  we  spun-off  the  development  of  the  second-generation  HDF  device  (“HDF2”)  into  a  newly-formed  subsidiary,  Specialty  Renal  Products,  Inc.
(“SRP”) and shortly thereafter SRP raised $3 million of outside equity capital directly to fund the second-generation development described above. We
maintain a 62.5% ownership stake in SRP. In February 2022, SRP raised an additional $0.5 million of equity capital, including an investment by Nephros
of $0.3 million, which was sufficient to maintain our 62.5% ownership stake in SRP. In addition to the equity capital raised by SRP, in December 2020, we
entered  into  a  loan  agreement  with  SRP  under  which  we  loaned  $1.3  million  to  SRP.  As  of  December  31,  2022,  the  outstanding  balance  of  this  loan,
including accrued interest, was approximately $1.4 million.

In May 2022, the FDA cleared HDF2 for patient use, which enables nephrologists to provide HDF treatment to patients with end stage renal disease. To
date, our and SRP’s HDF1 and HDF2 systems are the only HDF systems cleared by the FDA.

Following FDA clearance of HDF2, SRP’s management began exploring strategic partnerships and/or potential additional sources of financing to support a
commercial launch of the HDF2 device but has been unsuccessful in identifying any interested strategic partner or investor. By late February 2023, SRP
had nearly exhausted its capital resources.

In  March  2023,  SRP’s  board  of  directors  and  stockholders  determined  to  wind  down  SRP  operations  and  liquidate  its  remaining  assets,  due  to  capital
constraints. SRP’s cash resources are sufficient to satisfy all of its outstanding liabilities other than its outstanding loan to us. Accordingly, we expect that
SRP will assign all of its remaining assets, including its intellectual property rights in the HDF2 device, to us in partial satisfaction of its outstanding loan
balance of approximately $1.4 million. Although we have no current plans to do so, we may re-evaluate opportunities for the HDF2 device in the future.

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 facility in Las Vegas, Nevada.

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
ultrafiltration technology in conjunction with our filtration products, and for an exclusive supply arrangement for the filtration products. Under the License
and Supply Agreement, as amended, Medica granted to us 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, we granted to
Medica  an  exclusive  license  under  our  intellectual  property  to  make  the  filtration  products  during  the  term  of  the  License  and  Supply  Agreement.  The
filtration 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 and Supply 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. 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.

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 a 10-year option to purchase 300,000 shares of our common stock. Such
options expired in April 2022.

Sales and Marketing

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, we have contracted with Donastar LLC as our master
distributor.  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.

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  (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.

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, 2022, we had four U.S. patents, one Canadian patent, one Chinese patent, one French patent, one German patent, one Italian patent,
one United Kingdom patent, and one European patent. In addition, we have one pending patent application in the United States. Our pending US patent
application relates to filter technologies, including liquid purification filter systems that are particularly suited for use in harsh environments.

Trademarks

As of December 31, 2022, in the United States, we secured registrations of the trademarks AETHER, ENDOPUR, HYDRAGUARD, and NANOGUARD.
In the US, we filed trademark application for NEPHROS and BECAUSE WATER MATTERS. In the UK, we secured registrations for the trademark H2H,
NANOGUARD, NEPHROS HYDRAGUARD, OLPUR, and PATHOGUARD.

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.

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.

As defined in EU Medical Device Regulation (Council Regulations 2017/745), 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.

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 13485/2016 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 function; 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

Currently  we  are  in  the  process  to  seek  approval  for  CE  certification  under  EU  Medical  Device  Regulation  (Council  Regulations  2017/745).  Once
approved, the following products will have certification from BSI America for CE marking and adherence to ISO13485 standards as Class IIa (Rule 3)
medical devices:

● SSU-D/DSU-D/SSUmini Ultrafilters: 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, which allows us to sell our products
in the United States and Canada.

In  November  2020,  we  received  MDSAP  certification,  to  continue  sales  and  compliance  in  the  United  States  and  Health  Canada.  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.

Currently, we are in the process of expanding our MDSAP certification to include Brazil. Following the expansion of our MDSAP certificate, we will be
allowed to sell our products in the United States, Canada, Brazil, 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 and/or MDR (European Union) requirements.

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  $3  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,  2022,  we  employed  a  total  of  27  full-time  employees,  including  9  employed  in  sales/marketing/customer  support,  14  in  logistics,
general,  and  administrative,  and  4  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 2022, we laid-off 7 employees (approximately 15%
of our staff), and experienced limited voluntary turnover. 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
SEC’s website at http://www.sec.gov.

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, 2022, we had an accumulated deficit of $142.8 million as a result of historical operating losses. While we believe that revenues will
increase following our planned sales team expansion, 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.

If we are unable to achieve profitability, we will need additional capital to fund our operating activities. Such capital is likely to be from the sale of shares
of our common stock or other equity securities or from loans or other debt securities. However, there is no assurance that such capital will be available on
favorable terms or at all.

We may be unable to achieve or sustain revenue growth.

Our business is substantially dependent upon sales of the water filter products. Our ability to increase our revenues in future periods will depend on our
ability to increase sales of our water filter and other products we introduce in the future, which will, in turn, depend in part on our success in growing our
customer  base  and  reorders  from  those  customers.  Our  sales  from  water  filters  was  slightly  less  in  fiscal  2022  compared  to  fiscal  2021  and  there  is  no
assurance that we will be able to improve our sales in future periods. If we cannot achieve significant revenue growth for an extended period, our financial
results will be adversely affected, and our stock price may decline.

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

Our success depends on our ability to both maintain our existing customers and to continue growing our customer base. If we are unable to maintain and
further  grow  our  customer  base,  our  ability  to  grow  revenue  will  be  limited  and  we  will  have  difficulty  achieving  profitability.  Our  ability  to  grow  our
customer  base  also  depends  on  our  ability  to  continue  increasing  achieve  market  acceptance  of  our  water  filter  products,  including  among  healthcare
facility  customers,  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.

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. If we achieve our goal to increase our product revenue, we will need to also increase our supply requirements However,
our  contracted  manufacturers  could  experience  manufacturing  and  control  problems  in  connection  with  their  manufacture  of  our  products,  which  could
disrupt their ability 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.

We are dependent on third parties to supply us with our products to us, making us vulnerable to supply problems and price fluctuations.

We rely on third-party suppliers to provide us with certain components of our products. With respect to our proprietary filter material used in our DSU-H,
SSU-H, S100 and HydraGuardTM and HydraGuardTM – Flush filters, we rely on a single source supplier. Our agreement with that supplier will expire in
2025 and although our relationship with this supplier is good, there can be no assurance that our current agreement will guarantee uninterrupted supply or
that we will be able to renew the agreement on favorable terms, or at all. We depend on our suppliers to provide us and our customers with materials in a
timely manner that meet our and their quality, quantity and cost requirements. These suppliers may encounter problems during manufacturing for a variety
of reasons, any of which could delay or impede their ability to meet our demand and our customers’ demands.

Companies in the United States and around the world have experienced a disruption in the supply of certain components and raw materials, such as resins
and  polymers,  which  may  adversely  affect  us  and  our  ability  to  obtain  these  components  in  a  timely  manner,  in  the  volumes  we  require,  or  at  all.  In
addition, the prices of these components and other supplies we rely upon in the manufacture of our products may rise. For example, we and our suppliers
have recently experienced, and may continue to experience, rising costs due to inflation, such as costs of materials, labor and freight. If inflation continues
to rise, the prices of our components may rise, resulting in increased expenses to us that we may not be able to offset by raising the prices of our products.

Any supply interruption from our suppliers or failure to obtain additional suppliers for any of the components used in our products, or price increases of
these supplies, could have a material adverse effect on our business, financial condition and results of operations.

We operate with a limited senior management team and are dependent on our sales and marketing personnel. Our business could be harmed if we are
unable to attract and retain personnel necessary for our success.

We operate our business with only one person in senior management, which individual serves as our President & Chief Executive Officer, as well as our
Chief Financial Officer. Our dependence on a single officer to perform multiple functions exposes us to various risks, including the risk that one officer
may be unable to devote sufficient or timely attention to all aspects of operating our business and that in the event of a sudden departure of such officer we
may not be able to promptly identify a successor. We do not carry key person life insurance on any of our employees. If we are unable to recruit and retain
qualified personnel to our senior management teams, we will be unlikely to achieve our objectives of continuing to grow our company and our business
may otherwise be harmed.

In addition, our need to significantly increase our revenue is also dependent on the personnel in our sales and marketing organization. Although we have
recently added a number of new sales and marketing professionals, our success will depend on their ability to quickly integrate into our business and our
ability to develop and retain them as employees. Our ability to increase our sales revenue may be materially impaired if we experience attrition in our sales
and marketing organization.

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 water-filtration products, particularly to healthcare facility customers, 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.

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.

16

 
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.

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  in  the  event  that  the  COVID-19  pandemic
resurges.  During  the  pandemic,  we  saw  decreased  demand  for  our  hospital  filtration  products.  In  addition,  sales  to  new  customers  were  hindered  by
pandemic-related travel restrictions. Also, our commercial filtration products, which are primarily targeted at the hospitality and food service markets, saw
a decrease in demand, due to the closure or reduced occupancy of many hotels and restaurants. If these decreases in demand were to recur, 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.

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.

If we develop new water filter products in the future, we may be required to obtain regulatory approvals and clearances in the countries in which we
intend to sell such 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 new products to market and enhance our revenues.

Our current water filter products that we market and sell to healthcare facilities and dialysis centers have 510(k) clearance from the FDA. However, we will
need to continue developing new products in the future to continue to compete in our industry, and such new products may require obtaining regulatory
approvals in the U.S. and other jurisdictions in which we intend to market them.

We cannot ensure that 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.

18

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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.

19

 
 
 
 
 
 
 
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  4  granted  U.S.  patents  will  expire  at  various  times  from  2023  to  2039,  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.

20

 
 
 
 
 
 
 
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, 2022, our common stock has traded at prices ranging from a high of $5.14 to a low of $0.91 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;

21

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
● 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.

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.

22

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 March 1, 2023, 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.

Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations

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.

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.

Our commercial water filters improve the taste and odor of water and reduce biofilm, cysts, particulates, and scale build-up in downstream equipment. Our
products  are  marketed  primarily  to  the  food  service,  hospitality,  convenience  store,  and  health  care  markets,  and  also  sold  into  medical  institutions  to
supplement.

We  also  own  a  majority  stake  in  Specialty  Renal  Products,  Inc.  (“SRP”),  a  development-stage  medical  device  company  that  is  focused  primarily  on
developing hemodiafiltration (“HDF”) technology. On May 13, 2022, the FDA gave 510(k) clearance to SRP’s second-generation model of the OLpūrH2H
Hemodiafiltration System, which enables nephrologists to provide HDF treatment to patients with end stage renal disease.

In  January  2023,  SRP  management  began  exploring  strategic  partnerships  to  support  a  commercial  launch  of  the  HDF  product  but  was  successful  in
identifying a partner. By late February 2023, SRP had nearly exhausted its capital resources. Due to its limited capital and lack of prospects for securing a
strategic partnership or additional financing, the board of directors of SRP adopted a plan on March 6, 2023 to wind down SRP operations, liquidate its
remaining assets and dissolve the company. That plan was approved by SRP’s stockholders on March 9, 2023. We anticipate that SRP’s cash resources will
be  sufficient  to  satisfy  all  of  its  outstanding  liabilities  other  than  its  obligations  to  us  under  a  loan  with  an  outstanding  balance  of  approximately  $1.4
million. Accordingly, we expect that SRP will assign all of its remaining assets, including its intellectual property rights in the HDF2 device, to us in partial
satisfaction of its outstanding loan balance. Although we have no current plans to do so, we may re-evaluate opportunities for HDF in the future.

As a result of our November 2022 sale of substantially all of the assets used in our PDS business, we completely exited the PDS business, which we had
previously been reporting as a separate reportable operating segment for financial reporting purposes. As a result, we determined that our PDS business had
met the criteria for discontinued operations as of September 30, 2022. We no longer separately report the PDS business as a separate reportable segment in
our financial statements including in this Annual Report on Form 10-K for any of the periods presented.

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.

26

 
 
 
 
 
 
 
 
 
 
 
 
 
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. 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, including recently, 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  market  acceptance  of  our
products,  expense  management,  and  progress  in  achieving  positive  operating  cash  flow.  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.

Consolidated  gross  profit  margin  was  approximately  47%  for  the  year  ended  December  31,  2022,  compared  to  approximately  55%  for  the  year  ended
December 31, 2021. The decrease of approximately 8% was driven by increased shipping costs, as well as inventory reserve increases charged to expense,
for  expirations,  certain  product  obsolescence  and  adjustments  to  inventory  counts.  Responding  to  supply  chain  cost  increases,  we  implemented  a  broad
price increase beginning June 1, 2022, which helped to offset these expense increases. Our gross margins returned to 59% in the quarter ended December
31, 2022, well within our target range of 55-60%.

Interest Expense

Interest  expense  was  approximately  $20,000  for  the  year  ended  December  31,  2022  compared  to  $41,000  for  the  year  ended  December  31,  2021.  This
reduction is primarily related to a lower principal balance of the company’s secured note payable.

Interest Income

Interest income was approximately $14,000 for the year ended December 31, 2022 compared to approximately $10,000 for the ended December 31, 2021.
The increase in interest income is due to higher interest rates earned on invested cash balances.

Extinguishment of PPP loan

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

Other Income (Expense), net

Other  income  was  approximately  $64,000  for  the  year  ended  December  31,  2022,  compared  to  $17,000  for  the  year  ended  December  31,  2021.  This
increase is primarily related to the release of the cumulative translation adjustment from accumulated other comprehensive income (loss) on the liquidation
of a foreign entity, related to the closure in the second quarter of 2022, of Nephros International, a wholly owned subsidiary of Nephros, Inc.

Loss from discontinued operations

Loss from discontinued operations was approximately $2.8 million for the year ended December 31, 2022, compared to approximately $1.1 million for the
year ended December 31, 2021. The discontinued operations are related to the company’s former PDS operating segment. The increased loss is primarily
due to the impairment of the net assets of PDS that was sold, and reported in the third quarter of 2022 that totaled approximately $1.4 million.

Liquidity and Capital Resources

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, 2022, we had an accumulated deficit of $142.8 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, as well as our significantly reduced cash burn rates over the past
6 months, we believe that our existing cash resources together with our anticipated revenue, will be sufficient to fund our current operating plan through at
least the next 12 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 to
fund operations. If there were a decrease in the demand for our products due to either economic or competitive conditions, or if we are otherwise unable to
achieve our plan or achieve our anticipated operating results, there could be a significant reduction in liquidity due to our possible inability to cut costs
sufficiently. In such event, the Company may need to take further actions to reduce its discretionary expenditures, including further reducing headcount,
reducing spending on R&D projects and reducing other variable costs.

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

● the market acceptance of our products, and our ability to effectively and efficiently produce, market and sell our products;
● 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 toward the development, marketing, and sales of our water filtration products and working capital purposes.

Net cash used in operating activities was $3.2 million for the year ended December 31, 2022 compared to $1.4 million for the year ended December 31,
2021, an increase of $1.8 million. This increase of $1.8 million is due primarily to an increase in the net loss incurred of $3.2 million, partially offset by
approximately $1.4 million in non-cash charges for impairment of assets held for sale.

Net cash used in investing activities was $0.1 million for the year ended December 31, 2022 compared to $0.1 million for the year ended December 31,
2021.

Net cash provided by financing activities was approximately $43,000 for the year ended December 31, 2022. This was primarily from proceeds from the
exercise of warrants of $0.2 million and from the sale to Nephros of SRP preferred shares of $0.2 million, offset partially by payments of $0.3 million on
our secured note, payments of employee taxes on restricted stock of approximately $31,000, principal payments of approximately $3,000 on our finance
lease obligation and principal payments of approximately $3,000 on our equipment financing debt.

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.

Purchase Commitments

In exchange for the rights granted under the License and Supply Agreement with Medica (see Note 10 – 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, 2022, the Company has agreed to make minimum annual aggregate purchases from Medica of €3.5 million (approximately $3.7 million).
For the year ended December 31, 2022, aggregate purchase commitments totaled €3.2 million (approximately $3.4 million). The company has agreed with
Medica that it will make-up the €0.3 purchase shortfall based on anticipated future revenues.

Future purchase commitments under the License and Supply Agreement with Medica are as follows:

● 2023: €3,625,000
● 2024: €3,825,000
● 2025: €4,000,000

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.  (the  “Company”)  as  of  December  31,  2022  and  2021,  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,  2022,  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, 2022 and 2021, and the results of its
operations and its cash flows for each of the two years in the period ended December 31, 2022, 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 Matter

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.

Inventory Valuation

Critical Audit Matter Description

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.

How We Addressed the Matter in Our Audit

Addressing  the  matter  involved  performing  procedures  and  evaluating  audit  evidence  in  connection  with  forming  our  overall  opinion  on  the  financial
statements. The primary procedures we performed to address this critical audit matter included:

● 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.

On October 4, 2022, the Company entered into a definitive asset purchase agreement with a third party for the sale of substantially all of the Company’s
Pathogen Detection Systems (“PDS”) business, which had been previously reported as a separate reportable operating segment. As a result of the sale of
the  PDS  business,  we  completely  exited  the  PDS  business.  As  a  result,  we  determined  that  our  PDS  business  had  met  the  criteria  for  discontinued
operations  as  of  September  30,  2022.  We  no  longer  separately  report  the  PDS  business  as  a  separate  reportable  segment  in  our  financial  statements
including in this Annual Report for any of the periods presented.

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. After SRP’s formation, the Company assigned
to SRP all of the Company’s rights to three patents relating to the Company’s hemodiafiltration technology, 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  and  3221  Polaris  Avenue,  Las  Vegas,
Nevada 89102. 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.

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 the Company’s wholly owned
subsidiary Nephros International which was dissolved during the quarter ended June 30, 2022, and SRP, in which the Company maintains a controlling
interest. 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.

Discontinued Operations

See  Note  4,  Discontinued  Operations,  for  a  discussion  of  the  Company’s  significant  accounting  policy  surrounding  the  sale  of  substantially  all  of  the
Company’s PDS business.

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,  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

In February 2022, pursuant to a First Amendment to Series A Preferred Stock Purchase Agreement (the “Amendment”) among SRP and the holders of
SRP’s outstanding shares of Series A Preferred Stock, SRP issued and sold an additional 100,003 shares of its Series A Preferred Stock at a price of $5.00
per share, resulting in total gross proceeds of $500,015. See “Note 17 – Stockholders’ Equity – Noncontrolling Interest,” below. In addition to the funds
provided by the sale of these additional shares of Series A Preferred Stock, the Company and SRP continue to maintain a loan agreement under which the
Company agreed to lend up to $1.3 million to SRP, including the $1.0 million borrowed during the year ended December 31, 2020. These loaned funds
were used to fund SRP’s operating activities through the recent FDA 510(k) clearance process of SRP’s second-generation hemodiafiltration system, which
was initially submitted to the FDA on February 24, 2021 and which received 510(k) clearance on May 13, 2022. As of December 31, 2022, the outstanding
balance of this loan, including accrued interest, was approximately $1.4 million. It is not expected that this $1.4 million will be repaid, given the recent
decision to wind down SRP’s business.

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 $142.8 million  as  of  December  31,  2022.  These  operating  losses  and  negative  cash
flows raise substantial doubt of the company’s ability to continue as a going concern. However, during the second half of 2022, the Company took certain
actions  to  mitigate  these  conditions,  including  headcount  and  other  expense  reductions,  the  sale  of  PDS  assets  and  discontinuance  of  PDS  operations,
customer price increases, and the recruiting and acquisition of additional sales staff to grow revenues. The Company believes these actions, when fully
implemented, will alleviate the substantial doubt as to the Company’s ability to continue as a going concern. Furthermore, based on these actions, as well as
the 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  through  at  least  the  next  12  months  from  the  date  of  issuance  of  the  accompanying  consolidated  financial
statements. In the event that operations do not meet expectations, the Company may need to further reduce discretionary expenditures such as headcount,
R&D projects, and other variable costs, to alleviate any remaining substantial doubt as to the Company’s ability to continue as a going concern.

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, both in
programmatic  business  and  emergency  pathogen  outbreak  response.  In  addition,  sales  to  new  customers  during  2020  –  including  water  filtration  and
pathogen detection products – were hindered by pandemic-related travel restrictions. Also in 2020, 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 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 Company adopted this guidance as of January 1, 2022, and the guidance did not
have an impact on its consolidated financial statements.

38

 
 
 
 
 
 
 
 
 
 
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,  2022  and  2021,  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 recognizes an allowance that reflects a current estimate of credit losses expected to be incurred over the life of a financial asset, including
trade receivables. The Company continuously monitors collections and payments from its customers and maintains a provision for estimated credit losses.
The Company determines its allowance for doubtful accounts by considering a number of factors, including the length of time balances are past due, the
Company’s previous loss history, the customer’s current ability to pay its obligations to the Company and the expected condition of the general economy
and  the  industry  as  a  whole.  The  Company  writes  off  accounts  receivable  when  they  are  determined  to  be  uncollectible.  The  allowance  for  doubtful
accounts was approximately $0 and $1,000 as of December 31, 2022 and 2021, 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  10  –  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 non-lease 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. For the year ended December 31, 2022, See Note 4 Discontinued
Operations, for a discussion of the Company’s significant accounting policy surrounding the sale of substantially all of the Company’s PDS business and
related impairment charge. There were no impairment losses for long-lived assets recorded for the year ended December 31, 2021.

40

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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 5 – Revenue Recognition for further discussion.

Shipping and Handling Costs

Shipping and handling costs charged to customers are recorded as revenue and as cost of goods sold and were approximately $98,000 and $71,000 for the
years ended December 31, 2022 and 2021, 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 of approximately $64,000 for the year ended December 31, 2022, is primarily related to the release of the cumulative translation adjustment
from  accumulated  other  comprehensive  income  (loss)  on  the  liquidation  of  a  foreign  entity  and  of  gains  on  foreign  currency  transactions  related  to  the
closure in the second quarter of 2022 of Nephros International, a wholly owned subsidiary of Nephros, Inc. Other income 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.

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, 2022 and 2021.

42

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
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, 2022 and 2021, 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  loss  per  common  share  is  calculated  by  dividing  net  loss  available  to  common  shareholders  by  the  number  of  weighted  average  common  shares
issued  and  outstanding.  Diluted  loss  per  common  share  is  calculated  by  dividing  net  loss  available  to  common  shareholders  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 and unvested restricted stock, 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 potentially dilutive securities have been excluded from the computations of diluted weighted average shares outstanding as they would be
antidilutive:

Shares underlying options outstanding
Shares underlying warrants outstanding
Unvested restricted stock

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  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 substantially all of the assets 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.
In consideration for the acquisition of these assets, 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.
Pursuant to the purchase agreement with GenArraytion, the Company also agreed to make royalty payments to GenArraytion equal to 5% of net sales of
certain products by the Company over the next five years. However, as a result of the Company’s sale of its PDS business to a third party, the Company
will no longer make any net sales of GenArraytion products during such royalty period. (See Note 4 - Discontinued Operations).

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

The acquired intellectual property was being amortized over its estimated useful life of 10 years. With the sale of the PDS assets announced on October 11,
2022, this asset was classified as held-for-sale at the period ended September 30, 2022, and then tested for impairment and subsequently written down to
$0. (See Note 4 –Discontinued Operations).

Note 4 – Discontinued Operations

In  accordance  with  ASC  205-20,  Presentation  of  Financial  Statements:  Discontinued  Operations,  a  disposal  of  a  component  of  an  entity  or  a  group  of
components of an entity (disposal group) is required to be reported as discontinued operations if the disposal represents a strategic shift that has (or will
have)  a  major  effect  on  an  entity’s  operations  and  financial  results  when  the  disposal  group  meets  the  criteria  to  be  classified  as  held-for-sale.  The
consolidated statements of operations reported for current and prior periods report the results of operations of the discontinued operations, including the
impairment loss recognized as a component of net income (loss) separate from the net income (loss) from continuing operations.

On  October  4,  2022,  the  Company  entered  into  a  definitive  asset  purchase  agreement  with  a  third  party  pursuant  to  which  the  Company  agreed  to  sell
substantially all of the assets used in the Company’s PDS business. In consideration for the sale of these assets, the Company received $1,000 in cash at the
closing, and will receive potential royalties payable to Nephros for a seven-year period commencing on January 1, 2023 subject to a minimum gross margin
threshold. As such, the potential royalties payable to the Company are a gain contingency as they pertain to an uncertain event that will be resolved in
future  reporting  periods.  As  a  result,  the  Company  will  recognize  the  gain  contingency  when  it  is  probable  the  contingency  will  be  resolved,  which  is
ultimately when settled. The Company determined all of the required criteria for held-for-sale and discontinued operations classification were met as of
September  30,  2022.  During  the  third  quarter  as  part  of  presenting  these  assets  and  liabilities  as  held-for-sale  in  the  Condensed  Consolidated  Balance
Sheets, the Company evaluated the disposal group including the relevant intangible assets for impairment. Based upon the selling price less the costs of
sale, the Company determined the net carrying value of the assets held for sale were impaired, and the value of the asset group to be sold was $0.

In  May  2015,  the  Company  entered  into  a  Sublicense  Agreement  (the  “Sublicense  Agreement”)  with  CamelBak  Products,  LLC
(“CamelBak”).  Under  this  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 IWTD. 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 are 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 obligations. The Sublicense Agreement terminated on December 31, 2022.

Bellco License Agreement

On June 27, 2011, the Company entered into a License Agreement (as thereafter amended, 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,  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  deferred  and  subsequently
recognized  as  license  revenue  over  the  term  of  the  License  Agreement.  In  addition,  the  License  Agreement  also  provided  for  the  payment  of  certain
royalties to the Company based on the number of units of Products sold per year in the covered territory. The License Agreement expired in accordance
with its terms on December 31, 2021.

Note 6 – Fair Value Measurements

Assets and Liabilities Measured at Fair Value on a Recurring Basis

The  Company  evaluates  its  financial  assets  and  liabilities  subject  to  fair  value  measurements  on  a  recurring  basis  to  determine  the  appropriate  level  of
classification for each reporting period.

At  December  31,  2022  and  December  31,  2021,  the  Company’s  cash  equivalents  consisted  of  money  market  funds.  The  Company  values  its  cash
equivalents using observable inputs that reflect quoted prices for securities with identical characteristics and classify the valuation techniques that use these
inputs as Level 1.

At December 31, 2022 and December 31, 2021, the fair value measurements of the Company’s assets and liabilities measured on a recurring basis were as

The carrying amounts of cash and cash equivalents, accounts receivable, accounts payable and accrued expenses approximate fair value as of December 31,
2022 and 2021 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, 2022 and
2021  because  those  financial  instruments  bear  interest  at  rates  that  approximate  current  market  rates  for  similar  agreements  with  similar  maturities  and

Goodwill

Goodwill had a carrying value on the Company’s consolidated balance sheets of $0.8 million at December 31, 2022 and 2021, respectively. Goodwill has
been allocated to the Water Filtration segment. The Company concluded the carrying value of goodwill was not impaired as of December 31, 2022, or 2021
as the Company determined that it was not more likely than not that the fair value of goodwill was less than its carrying value.

Note 10 – 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

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 $1.7 million from December 31, 2021 to December 31,
2022.

At December 31, 2022, the Company had Federal income tax net operating loss carryforwards of $82.3 million and State income tax net operating loss
carryforwards of $5.6 million. The Company had Federal research and development tax credit carryforwards of $1.4 million at December 31, 2022. 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 $16.6 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 2022 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 2017 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.

Stock Plans

In 2015, the Board of Directors adopted the Nephros, Inc. 2015 Equity Incentive Plan (“2015 Plan”). As of December 31, 2022 including amendments
approved by the Board of Directors, 2,547,400 shares of common stock were approved for issuance pursuant to stock options, restricted stock and other
equity incentive awards to the Company’s employees, directors and consultants. The maximum contractual term for stock options granted under the 2015
Plan is 10 years.

As of December 31, 2022, options to purchase 1,339,328 shares of common stock had been issued to employees under the 2015 Plan and were outstanding.
The options issued to employees expire on various dates between April 15, 2025 and November 1, 2032. Taking into account all options and restricted
stock  granted  under  the  2015  Plan,  there  are  664,741  shares  available  for  future  grant  under  the  2015  Plan.  Generally,  grants  vest  based  on  a  service
condition only and vest between two to four years.

The Company’s previously adopted and approved plan, the 2004 Stock Incentive Plan (“2004 Plan”), expired in the year ended December 31, 2014. As of
December 31, 2022, options to purchase 26,037 shares of common stock had been issued to employees under the 2004 Plan and were outstanding. The
options  expire  on  various  dates  between  May  23,  2023  and  March  26,  2024.  No  shares  are  available  for  future  grants  under  the  2004  Plan.  Options
currently outstanding are fully vested.

Stock Options

The Company has elected to recognize forfeitures as they occur. Stock-based compensation expense recognized for the years ended December 31, 2022 and
2021 was $0.9 million and $0.9 million, respectively.

For the year ended December 31, 2022, $0.8 million and approximately $63,000 are 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, 2021, $0.9 million and approximately $48,000 are included in selling, general and administrative expenses and research and development expenses,
respectively, on the accompanying consolidated statement of operations and comprehensive loss.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The below assumptions for the risk-free
interest rates, expected dividend yield, expected lives and expected stock price volatility were utilized for the stock options granted during the year ended
December 31, 2022.

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  2022  and  2021  is  $1.25  and  $4.94,  respectively.  The  aggregate  intrinsic  values  of  stock  options
outstanding and stock options vested or expected to vest as of December 31, 2022 was approximately $0 for each. 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, 2022 was 6.0 years.

The intrinsic values of stock options exercised was approximately $265,000 for the year ended December 31, 2021. No stock options were exercised for the
year ended December 31, 2022.

As of December 31, 2022, there was $0.9 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 1.93 years.

There was no tax benefit related to expense recognized in the twelve months ended December 31, 2022 and 2021, as the Company is in a net operating loss
position.

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, 2022 and 2021 was $0.4 million and $0.2 million, respectively.

Total stock-based compensation expense for restricted stock was approximately $42,000 and $333,000 for the year ended December 31, 2022 and 2021,
respectively and is recognized in selling, general and administrative expenses on the accompanying consolidate statement of operations and comprehensive
loss.

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,  2022,  there  was  no  unrecognized  compensation  expense  related  to  restricted  stock-based  awards  granted  under  the  equity
compensation plans, and during the year ended December 31, 2022, 15,000 shares of restricted stock were forfeited as the conditions on the vesting of the
restricted stock could not be met.

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 (the “SRP Plan”) was approved on May 7, 2019 under which 150,000 shares of SRP’s common stock are reserved for the
issuance of options, restricted stock and other stock awards.

There were no SRP stock options granted during the year ended December 31, 2022. SRP issued 29,880 shares of restricted stock pursuant to the SRP Plan
during year ended December 31, 2022. Stock-based compensation expense related to the SRP stock grants was approximately $47,000 for the year ended

identified therein (the “SRP Purchase Agreement”), SRP sold to such purchasers an aggregate of 600,000 shares of its Series A Preferred Stock (the “Series
A Preferred”) at a price of $5.00 per share resulting in total gross proceeds of $3.0 million. On February 1, 2022, SRP entered into a First Amendment to
the  SRP  Purchase  Agreement  (the  “SRP  Amendment”)  with  the  holders  of  its  outstanding  shares  of  Series  A  Preferred.  The  purpose  of  the  SRP
Amendment was to permit SRP to sell up to an additional 100,003 shares of Series A Preferred 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  SRP  Amendment,  on  February  4,  2022,  SRP
conducted  a  closing  in  which  it  sold  100,003  shares  of  Series  A  Preferred,  resulting  in  gross  proceeds  of  $500,015.  Approximately  $188,000  of  the
proceeds were recorded as an increase to the equity of the non-controlling interests. 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  313  shares,  and  Lambda  Investors  LLC  (“Lambda”),  an  affiliate  of  Wexford  Capital,  which
beneficially owns approximately 36% of the Company’s common stock, which purchased 25,938 shares of SRP’s Series A Preferred. Such purchases were
made on the same terms as all other purchasers. In addition to the funds provided by the SRP Purchase Agreement, Nephros and SRP continue to maintain
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  loaned  funds  were  used  to  fund  SRP’s  operating  activities  through  the  recent  FDA  510(k)  clearance  process  of  SRP’s  second-generation
hemodiafiltration system, which was initially submitted to the FDA on February 24, 2021 and which received 510(k) clearance on May 13, 2022. As of
December 31, 2022, the outstanding balance of this loan, including accrued interest, was $1.4 million.

Each  share  of  SRP  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 purchase price of the Series A Preferred, 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.

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.

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  interim
balance sheet, as the noncontrolling interest is redeemable only upon the occurrence of events that are within the control of the Company.

In March 2023, the board of directors of SRP adopted, and the stockholders of SRP approved, a plan to wind up SRP’s operations and dissolve. See Note
21 – Subsequent Event, below.

Warrants Exercised During 2022 and 2021

During the year ended December 31, 2022, warrants to purchase 60,374 shares of the Company’s common stock were exercised, resulting in proceeds of
$0.2 million and the issuance of 60,374  shares  of  the  Company’s  common  stock.  Of  the  warrants  exercised  during  the  year  ended  December  31,  2022,
warrants to purchase 14,815 shares of the Company’s common stock were exercised by members of management, resulting in proceeds of approximately
$40,000. Warrants to purchase 63,102 shares of the Company’s common stock expired unexercised, during the year ended December 31, 2022.

During  the  year  ended  December  31,  2021,  the  Company  issued  an  aggregate  of  120,966  shares  of  its  common  stock  upon  the  exercise  of  outstanding
warrants relating to an aggregate of 126,008 shares of common stock. Of such 120,966 shares issued, 110,003 were issued in cash exercises resulting in
gross  proceeds  to  the  Company  of  $0.3  million  (the  “Cash  Exercises”)  and  10,963  shares  were  issued  in  connection  with  cashless  (net)  exercises  of
outstanding warrant relating to 16,005 shares of common stock (the “Cashless Exercises”). Among the shares issued in connection with the Cash Exercises,
66,667  shares  were  issued  to  the  Company’s  largest  stockholder,  which  resulted  in  proceeds  to  the  Company  of  $0.2  million.  Among  the  Cashless
Exercises, 4,570 shares of common stock were issued to persons affiliated with members of the Company’s management upon the exercise of warrants
relating to 6,669 shares.

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 $104,000
and $92,000 to the SIMPLE IRA in 2022 and 2021, respectively.

Note 19 - Commitments and Contingencies

Purchase Commitments

In exchange for the rights granted under the License and Supply Agreement with Medica (see Note 10 – 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, 2022, the Company has agreed to make minimum annual aggregate purchases from Medica of €3.5 million (approximately $3.7 million).
For the year ended December 31, 2022, the Company’s aggregate purchase commitments totaled €3.2 million (approximately $3.4 million). The company
has agreed with Medica that it will make-up the €0.3 purchase shortfall based on anticipated future revenues.

Future purchase commitments to under the License and Supply Agreement with Medica are as follows:

● 2023: €3,625,000
● 2024: €3,825,000
● 2025: €4,000,000

Note 20 – Segment Reporting

The  Company  has  defined  three  reportable  segments:  Water  Filtration,  Pathogen  Detection  and  Renal  Products.  During  the  period  ended  December  31,
2022,  it  was  determined  the  Pathogen  Detection  segment  was  to  be  treated  as  a  discontinued  operation  (See  Note  4  –Discontinued  Operations).  For
purposes of this segment reporting, the Company is reporting only on the remaining two segments that are considered part of continuing operations.

The  Water  Filtration  segment  primarily  develops  and  sells  high  performance  water  purification  filters.  The  Renal  Products  segment  is  focused  on  the
development  of  medical  device  products  for  patients  with  renal  disease,  including  a  second  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
Significant Accounting Policies.

As of December 31, 2022, $0.1 million of total assets in the Renal Products segment consisted of cash received from the loan agreement between Nephros
and SRP.

Note 21 – Subsequent Event

On  March  6  2023,  the  Board  of  Directors  of  Specialty  Renal  Products,  Inc.  (“SRP”),  the  Company’s  subsidiary,  approved  a  plan  to  wind  down  SRP’s
operations, liquidate SRP’s remaining assets and dissolve the company, which plan was approved by SRP’s stockholders on March 9, 2023. As of such
date, the SRP Board of Directors believes that SRP’s cash resources are sufficient to satisfy the company’s outstanding liabilities, other than its obligations
under the loan agreement between SRP and the Company pursuant to which SRP has an existing balance of outstanding principal and accrued interest of
approximately $1.4 million. As a result, the Company does not expect to receive cash repayment of such indebtedness, but anticipates that all of SRP’s
remaining assets, including all of its rights and interests in and to the technology and assets related to its second generation HDF product, will be assigned
to  the  Company  in  partial  satisfaction  of  such  indebtedness.  The  holders  of  SRP’s  outstanding  common  stock  and  preferred  stock  are  not  expected  to
receive any return of capital from the liquidation of SRP.

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

There were no disagreements with the accountants during 2022 or 2021.

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,  2022.  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,  2022.
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, 2022 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, 2022, the internal control over financial reporting was effective as of December 31, 2022.

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.

Item 9B. Other Information

On  March  6  2023,  the  Board  of  Directors  of  Specialty  Renal  Products,  Inc.  (“SRP”),  the  Company’s  subsidiary,  approved  a  plan  to  wind  down  SRP’s

(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

over financial reporting.
