ITEM 1. BUSINESS
Item 1. Business
Overview
We are a commercial-stage company that develops and sells high performance water solutions to the medical and commercial markets.
In medical markets, we sell water filtration products. 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.
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 rapidly expand 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. Through our employee sales staff, we have sold products directly to a number of convenience stores, hotels, casinos, and restaurants. We have also signed an agreement with a partner to be the exclusive distributor to resell select water filters and related products to customers in the commercial food and beverage markets subject to meeting certain minimum thresholds.
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 2023, according to the American Hospital Association, there are approximately 6,129 hospitals in the U.S., with approximately 920,000 beds. Over 34 million patients were admitted to these hospitals. The U.S. Department of Health and Human Services estimates that healthcare associated infections (“HAI”) occur in approximately 1 out of every 31 hospital patients, which calculates to over one million patients in 2023. 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.
Our complete hospital infection control product line, including in-line, and point-of-use can be viewed on our website at https://www.nephros.com/infection-control/. We are not including the information on our website as a part of, nor incorporating it by reference into, this Annual Report on Form 10-K.
Dialysis Centers - Water/Bicarbonate. In the dialysis water market, Nephros ultrafiltration products are among the highest performing products on the market. The DSU-D, SSU-D and the SSUmini have become the standard endotoxin filter in many portable reverse osmosis systems. The EndoPur®, our large-format ultrafilter targeted at dialysis clinic water systems, provides the smallest pore size available.
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 National Institute of Health, there are approximately 7,100 dialysis clinics in the United States servicing approximately 500,000 patients annually. We estimate that there are over 100,000 hemodialysis machines in operation in the United States.
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 entered into an agreement to provide water filtration systems to an organization that services approximately 3,000 Quick Service Restaurants (“QSR”). Effective January 1, 2023, we entered into a new supply agreement with this commercial partner, which superseded the March 2022 agreement. Under the January 2023 agreement, we engaged this commercial partner to be our exclusive distributor to the food, beverage and hospitality industries. We continue to pursue other national accounts, which, over time, 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 provides 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.
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.
We previously held a majority stake in Specialty Renal Products, Inc. (“SRP”), a development-stage medical device company that was focused primarily on the development of the second-generation HDF device (“HDF2”). SRP undertook efforts to redesign and dramatically simplify our HDF device. We believe those updates made the system significantly easier to use. 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 unsuccessful in identifying a partner. By late February 2023, SRP had nearly exhausted its capital resources and, 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, and on April 13, 2023, SRP filed a certificate of dissolution with the State of Delaware. SRP’s cash resources were sufficient to satisfy all of its outstanding liabilities other than its obligations to us under a loan with an outstanding balance of approximately $1.5 million. Accordingly, SRP assigned to us all of its remaining assets, including its intellectual property rights in the HDF2 device, in 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.

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 South Orange, New Jersey.
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 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, 2028, 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 per month at the EURIBOR 360-day rate plus 500 basis points calculated on the principal amount of any outstanding invoices that are overdue by more than 15 days beyond 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.
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. patent for the “Method and Apparatus for a Hemodiafiltration Module for use with a Dialysis Machine,” has 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, 2023, we had four U.S. patents and one Canadian 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, 2023, in the United States, we secured registrations of the trademarks ENDOPUR, HYDRAGUARD, NANOGUARD, and NEPHROS. In the US, we filed two trademark applications for BECAUSE WATER MATTERS. In the UK, we secured registrations for the trademarks NANOGUARD, NEPHROS HYDRAGUARD, 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 into 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.
In November 2023, we received approval for expansion of our MDSAP certification to include Brazil. This expansion provides Nephros the approval to sell the following medical devices in Brazil:
● SSSUmini Ultrafilters: Intended to be used to filter water or bicarbonate concentrate used in hemodialysis procedures.
● EndoPur Filters: 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.).
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, 2023, we employed a total of 31 full-time employees, including 11 employed in sales/marketing/customer support, 15 in logistics, general, and administrative, and 4 in research and development and 1 in manufacturing. 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 2023, we had 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.

ITEM 1A. RISK FACTORS
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, 2023, we had an accumulated deficit of $144.4 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 and future prospects are substantially dependent upon our ability to significantly grow our product revenue. Although our sales were approximately 43% higher in 2023 compared to 2022, there is no assurance that we will be able to continue our sales growth in future periods. Our ability to increase our revenues in future periods will depend on our ability to significantly grow our customer base and then consistently obtaining product reorders from those customers. If we cannot sustain 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 are successful in continuing 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. In particular, our ability to grow sales in our commercial business depends largely on the efforts of a distribution partner with respect to which we have given exclusive distribution rights to our products in the food, beverage and hospitality markets. 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 2028 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 highly 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 a two-person senior management team. We have a Chief Executive Officer and a Chief Financial Officer, who together directly oversee operations, sales and finances. Our dependence on two officers to perform multiple functions exposes us to various risks, including the risk that two officers 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 one 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.
We rely on information technology systems and network infrastructure to operate and manage our business. If we experience a breach, cyber attack or other disruption to these systems or data, our business, results of operations and financial condition could be adversely affected.
We are increasingly dependent on sophisticated information technology systems to operate our business, including to process, transmit and store sensitive data. Specifically, we rely on our information technology systems to effectively manage sales and marketing, accounting and financial functions, inventory management, and our research and development data. Our business therefore depends on the continuous, effective, reliable, and secure operation of our computer hardware, software, networks, Internet servers, and related infrastructure.
Although we believe our computer and communications hardware is protected by reasonable physical, technical, and administrative safeguards, it is still vulnerable to system malfunction, computer viruses, and cybersecurity breaches - including ransomware, phishing, malware, brute force, insider threats, and other cyber attacks and security incidents. These events could lead to the unauthorized access to information systems maintained by us or our service providers or customers and result in the misappropriation or unauthorized disclosure of confidential information belonging to us, our employees, customers, distributors or our suppliers. The techniques used by criminal elements to attack computer systems are sophisticated, change frequently and may originate from less regulated and remote areas of the world, including countries that engage in state-sponsored cyber attacks. As a result, we may not be able to address these techniques proactively or implement adequate preventative measures. Additionally, the regulatory environment governing information, security and privacy laws is increasingly demanding and continues to evolve. If our information technology systems are compromised, we could be subject to fines, damages, litigation and enforcement actions and we could lose trade secrets or other confidential information, the occurrence of which could harm our reputation, business, results of operations and financial condition.
Our information systems, and those of third parties with whom we contract, also require an ongoing commitment of significant resources to maintain, protect and enhance existing systems and develop new systems to keep pace with continuing changes in information technology. The failure of our information technology systems to perform as we anticipate or our failure to effectively implement new systems could disrupt our operations and could result in decreased sales, increased overhead costs, excess inventory and product shortages, all of which could have a material adverse effect on our reputation, business, results of operations and financial condition.
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.
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.
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.
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.
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 2029 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.
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
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, 2023, our common stock has traded at prices ranging from a high of $6.19 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:
● period-to-period fluctuations in our results of operations;
● sales of our common stock or other financing transactions;
● announcements of technological innovations or new commercial products by our competitors or us;
● developments concerning proprietary rights, including patents;
● achievement or rejection of regulatory approvals by our competitors or us;
● regulatory developments in the United States and foreign countries;
● economic or other crises and other external factors;
● threatened or actual litigation; and
● changes in financial estimates by securities analysts.
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.
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.
We have never paid dividends and do not intend to pay cash dividends.
We have never paid dividends on our common stock and currently do not anticipate paying cash dividends on our common stock for the foreseeable future. Consequently, any returns on an investment in our common stock in the foreseeable future will have to come from an increase in the value of the stock itself. As noted above, the lack of an active trading market for our common stock will make it difficult to value and sell our common stock. While our dividend policy will be based on the operating results and capital needs of our business, we anticipate that all earnings, if any, will be retained to finance our future operations.
Several provisions of the Delaware General Corporation Law, our fourth amended and restated certificate of incorporation, as amended, and our second amended and restated bylaws could discourage, delay or prevent a merger or acquisition, which could adversely affect the market price of our common stock.
Several provisions of the Delaware General Corporation Law, our fourth amended and restated certificate of incorporation, as amended, and our second amended and restated bylaws could discourage, delay or prevent a merger or acquisition that stockholders may consider favorable, and the market price of our common stock could be reduced as a result. These provisions include:
● authorizing our board of directors to issue “blank check” preferred stock without stockholder approval;
● providing for a classified board of directors with staggered, three-year terms;
● prohibiting us from engaging in a “business combination” with an “interested stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder unless certain provisions are met;
● prohibiting cumulative voting in the election of directors;
● limiting the persons who may call special meetings of stockholders; and
● establishing advance notice requirements for nominations for election to our board of directors or for proposing matters that can be acted on by stockholders at stockholder meetings.
As a smaller reporting company with little or no name recognition and with several risks and uncertainties that could impair our business operations, we are not likely to generate widespread interest in our common stock. Without widespread interest in our common stock, our common stock price may be highly volatile and an investment in our common stock could decline in value.
Unlike many companies with publicly traded securities, we have little or no name recognition in the investment community. We are a relatively new company and very few investors are familiar with either our company or our products. We do not have an active trading market in our common stock, and one might never develop, or if it does develop, might not continue.
Additionally, the market price of our common stock may fluctuate significantly in response to many factors, many of which are beyond our control. Risks and uncertainties, including those described elsewhere in this “Risk Factors” section could impair our business operations or otherwise cause our operating results or prospects to be below expectations of investors and market analysts, which could adversely affect the market price of our common stock. As a result, investors in our common stock may not be able to resell their shares at or above their purchase price and could lose all of their investment.
Securities class action litigation is often brought against public companies following periods of volatility in the market price of such company’s securities. We may become subject to this type of litigation in the future. Litigation of this type could be extremely expensive and divert management’s attention and resources from running our company.
Our directors, executive officers, and Wexford Capital LP (“Wexford”) control a significant portion of our stock and, if they choose to vote together, could have sufficient voting power to control the vote on substantially all corporate matters.
As of March 1, 2024, Wexford, our largest stockholder, beneficially owned approximately 35% of our outstanding common stock. Collectively, Wexford, our directors and our executive officers beneficially owned approximately 37.5% 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
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 are also sold into medical institutions to supplement our medical filters.
We previously held a majority stake in Specialty Renal Products, Inc. (“SRP”), a development-stage medical device company that was 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 unsuccessful in identifying a partner. By late February 2023, SRP had nearly exhausted its capital resources and, 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, and on April 13, 2023, SRP filed a certificate of dissolution with the State of Delaware. SRP’s cash resources were sufficient to satisfy all of its outstanding liabilities other than its obligations to us under a loan with an outstanding balance of approximately $1.5 million. Accordingly, SRP assigned to Nephros all of its remaining assets, including its intellectual property rights in the HDF2 device, in 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.
Recent Accounting Pronouncements
We are subject to recently issued accounting standards, accounting guidance and disclosure requirements. For a description of these new accounting standards, see “Note 2 - Summary of Significant Accounting Policies,” to our consolidated financial statements included in Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K.
Critical Accounting Policies and Estimates
Our discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). The preparation of financial statements in accordance with GAAP requires application of management’s subjective judgments, often requiring estimates about the effect of matters that are inherently uncertain and may change in subsequent periods. Our actual results may differ substantially from these estimates under different assumptions or conditions. While our significant accounting policies are described in more detail in “Note 2 - Summary of Significant Accounting Policies,” to our consolidated financial statements included in Item 8, “Financial Statements and Supplementary Data,” of this Annual Report on Form 10-K, we believe that the following accounting policies require the application of significant judgments and estimates.
Inventories
Our inventory reserve requirements are based on various factors including product expiration date and estimates for the future sales of the product. Reserve assessments include inventory obsolescence based upon expiration date, damaged, or rejected product, slow-moving products, and other considerations. 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 continuing to achieve 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.
Fiscal Year Ended December 31, 2023, Compared to the Fiscal Year Ended December 31, 2022
The following table sets forth our summarized, consolidated results of operations for the years ended December 31, 2023 and 2022 (in thousands except percentages):
Years Ended December 31, $

Less: undeclared deemed dividend attributable to continuing noncontrolling interest - (276 ) (100 )%
Net loss attributable to Nephros, Inc. shareholders $ (1,575 ) $ (7,382 ) 5,807 (79 )%
Net Revenues.
Total net revenues increased 43% in the year ended December 31, 2023, driven by investments in our executive and sales organizations, as well as partnering with a master distributor for much of our commercial business.
Gross Profit Margin
Gross profit margin was approximately 59% for the year ended December 31, 2023, compared to approximately 47% for the year ended December 31, 2022. The increase of approximately 12 percentage points reflects a return to target gross margins of 55%-60%. Lower gross margins in 2022 were primarily driven by large inventory write-downs due to expired product, and higher shipping expense from supply chain disruptions.
Research and Development Expenses
Research and development expenses decreased 30% primarily due to the wind down of SRP in 2023 and consequently a reduction in SRP-related research and development expense of $0 in 2023 versus $376,000 in 2022, and slightly decreased investment in 2023 in water filter research and development.
Depreciation and Amortization Expense
Depreciation and amortization expenses were $0.2 million for each of the years ended December 31, 2023 and 2022.
Selling, General and Administrative Expenses
Selling, general and administrative expenses increased $1.3 million or 17%, primarily due to increased bonus and sales commission expense associated with higher sales, the hiring of a new CEO and CFO to replace one person acting in both positions, and increased hires to support the sales organization.
Interest Expense
Interest expense was approximately $2,000 for the year ended December 31, 2023 compared to $20,000 for the year ended December 31, 2022. This reduction is primarily related to a lower principal balance of the company’s secured note payable.
Interest Income
Interest income was approximately $64,000 for the year ended December 31, 2023 compared to approximately $14,000 for the ended December 31, 2022. The increase in interest income is due to higher interest rates earned on invested cash balances.
Other Income (Expense), net
Other expense was approximately $44,000 for the year ended December 31, 2023, compared to other income of $64,000 for the year ended December 31, 2022. This decrease is primarily a result of losses on foreign currency transactions in 2023. For the year ended December 31, 2022, other income 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, our wholly-owned subsidiary.
Loss from discontinued operations
Loss from discontinued operations was approximately $2.8 million for the year ended December 31, 2022. The discontinued operations are related to the company’s former PDS operating segment.
Liquidity and Capital Resources
The following table summarizes our liquidity and capital resources as of December 31, 2023 and 2022 and is intended to supplement the more detailed discussion that follows. The amounts stated are expressed in thousands.
As of December 31,
Liquidity and Capital Resources
Cash and cash equivalents $ 4,307 $ 3,634
Other current assets 4,098 4,627
Working capital 6,292 6,849
Stockholders’ equity 8,358 8,881
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, 2023, we had an accumulated deficit of $144.4 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 the fact that we generated $0.7 million in cash flow in 2023, 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 provided by operating activities was $0.8 million for the year ended December 31, 2023 compared to net cash used in operating activities of approximately $3.2 million for the year ended December 31, 2022, an increase of $4.1 million. This increase of $4.1 million is due primarily to a decrease in the net loss incurred of $5.5 million, in addition there was approximately $1.4 million in non-cash charges for impairment of assets held for sale in 2022.
Net cash used in investing activities was $0.1 million for the years ended December 31, 2023 and 2022
Net cash used in financing activities was approximately $79,000 for the year ended December 31, 2023. This was primarily from payments of $71,000 on our secured note, principal payments of approximately $7,000 on our finance lease obligation and principal payments of approximately $1,000 on our equipment financing debt.
Net cash provided by financing activities was $34,000 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 $12,000 on our finance lease obligation and principal payments of approximately $3,000 on our equipment financing debt.
Purchase Commitments
In exchange for the rights granted under the License and Supply Agreement with Medica (see Note 9 - License and Supply Agreement, net), the Company agreed to make certain minimum annual aggregate purchases from Medica over the term of the License and Supply Agreement. For the year ended December 31, 2023, the Company had agreed to make minimum annual aggregate purchases from Medica of €3.8 million (approximately $4.1 million). For the year ended December 31, 2023, aggregate purchase commitments totaled €4.9 million (approximately $5.3 million). All purchase agreements were met.
Future purchase commitments under the License and Supply Agreement with Medica are as follows:
● 2024: €4,208,000
● 2025: €4,629,000
● 2026: €4,976,000

Item 8. Financial Statements and Supplementary Data
Report of Independent Registered Public Accounting Firm
To the Board of Directors and Stockholders of
Nephros, Inc.
Opinion on the Financial Statements
We have audited the accompanying balance sheets of Nephros, Inc. (the “Company”) as of December 31, 2023 and 2022, and the related 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, 2023, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2023, 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 financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.
Our audits included performing procedures to assess the risks of material misstatement of the 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 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

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 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. On March 9, 2023, the SRP Stockholders approved a plan of dissolution to wind down SRP’s operations, liquidate SRP’s remaining assets and dissolve SRP. Pursuant to such plan, SRP filed a certificate of dissolution with the State of Delaware on April 13, 2023. As a result of the SRP Stockholders’ approval of the plan of dissolution and provisions therein and after satisfying all of SRP’s liabilities, there are no assets available for distribution to the holders of any of SRP’s capital stock, including its Series A Preferred Stock. As such, the value recorded to non-controlling interest was written to zero and the impact reclassified to the Company’s additional paid-in capital as the Company retained control of SRP.
The Company’s primary U.S. facility is located at 380 Lackawanna Place, South Orange, New Jersey 07079. This location along with our Whippany, NJ facility, houses the Company’s corporate headquarters, research, manufacturing, and distribution facilities.
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, which was dissolved pursuant to a plan of dissolution adopted by its stockholders on March 9, 2023 and the subsequent filing of a certificate of dissolution with the State of Delaware on April 13, 2023. All intercompany accounts and transactions were eliminated in the preparation of the accompanying consolidated financial statements.
Discontinued Operations
See Note 3, 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.
Reclassifications
Certain reclassifications were made to the prior year’s amounts to conform to the 2023 presentation. On the Consolidated Statements of Cash Flows, Inventory impairments and writeoffs reported as $623,000 for the year ended December 31, 2022, was increased to $773,000, and Inventory reported as $915,000 for the year ended December 31, 2022 was decreased to $765,000, to accurately reflect the non-cash portion of the change in inventories for the year ended December 31, 2022.
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 15 - 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 also maintained a loan agreement under which the Company loaned $1.3 million to SRP, of which $1.0 million had been loaned during the year ended December 31, 2020. These loaned funds were used to fund SRP’s operating activities through the 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. In connection with SRP’s plan of dissolution and pursuant to an agreement between the Company and SRP entered into on May 24, 2023, SRP assigned substantially all of its remaining assets to the Company in satisfaction of the entire loan balance. Accordingly, as of December 31, 2023, there was no outstanding balance of this loan.
The Company has sustained operating losses every quarter through December 31, 2023, generating an accumulated deficit of $144.4 million as of December 31, 2023. Throughout 2023, however, the Company’s operating cash flows have been positive due to increased sales, improved gross margins, careful expense management, and the dispositions of the PDS and SRP businesses. These actions resulted in the Company generating cash from operations of approximately $0.8 million through the twelve months ended December 31, 2023. Based on these positive cash flows, the Company believes that its cash balances are 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. However, in the event that the Company’s operating results do not meet its expectations, the Company may need to further reduce discretionary expenditures such as headcount, R&D projects, and other variable costs.
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.
Major Customers
For the years ended December 31, 2023 and 2022, the following customers accounted for the following percentages of our revenues, respectively:

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. The company also classifies, as cash equivalents, certificates of deposit with an original maturity of greater than three months for which there is no cost to withdrawal funds prior to maturity date. At December 31, 2023 and 2022, 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 credit losses 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 $11,000 and $0 as of December 31, 2023 and 2022, 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, 2028. The Company determines amortization periods for licenses based on its assessment of various factors impacting estimated useful lives and cash flows of the acquired rights. Such factors include the expected launch date of the product, the strength of the intellectual property protection of the product and various other competitive, developmental, and regulatory issues, and contractual terms. See Note 9 - License and Supply Agreement, net for further discussion.
Leases
The Company determines if an arrangement contains a lease at inception. Leases are included in lease right-of-use (“ROU”) assets and lease liabilities on the consolidated balance sheet.
Lease ROU assets and lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of future payments. The operating lease ROU asset includes any lease payments made and initial direct costs incurred and excludes lease incentives. The Company’s lease terms may include options to extend or terminate the lease when it is reasonably certain that the Company will exercise that option. Lease expense for minimum lease payments is recognized on a straight-line basis over the lease term.
The Company has elected as an accounting policy not to apply the recognition requirements in ASC 842 to short-term leases. Short-term leases are leases that have a term of 12 months or less and do not include an option to purchase the underlying asset that the Company is reasonably certain to exercise. The Company recognizes the lease payments for short-term leases on a straight-line basis over the lease term.
The Company has also elected, as a practical expedient, by underlying class of asset, not to separate lease components from 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 3 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, 2023.
Intangible Assets
The Company’s intangible assets include finite lived assets. Finite lived intangible assets, consisting of customer relationships, tradenames, service marks and domain names are amortized on a straight-line basis over the estimated useful lives of the assets.
Finite lived intangible assets are tested for impairment when events or changes in circumstances indicate that the carrying value of the asset may not be recoverable. Impairment testing requires management to estimate the future undiscounted cash flows of an intangible asset using assumptions believed to be reasonable, but which are unpredictable and inherently uncertain. Actual future cash flows may differ from the estimates used in the impairment testing.
Goodwill
Goodwill represents the excess of purchase price over the fair value of net assets acquired. In accordance with ASC 350, “Goodwill and Other Intangibles,” rather than recording periodic amortization, goodwill is subject to an annual assessment for impairment by applying a fair value-based test. If the fair value of the reporting unit exceeds the reporting unit’s carrying value, including goodwill, then goodwill is considered not impaired, making further analysis not required. The Company reviews goodwill for possible impairment annually during the fourth quarter, or whenever events or circumstances indicate that the carrying amount may not be recoverable.
Fair Value Measurements
The Company measures certain financial instruments and other items at fair value.
To determine the fair value, the Company uses the fair value hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs market participants would use to value an asset or liability and are developed based on market data obtained from independent sources. Unobservable inputs are inputs based on assumptions about the factors market participants would use to value an asset or liability.
To measure fair value, the Company uses the following fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable:
Level 1 - Quoted prices in active markets for identical assets or liabilities.
Level 2 - Inputs other than Level 1 that are observable for the asset or liability, either directly or indirectly, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets or liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data by correlation or other means.
Level 3 - Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Value is determined using pricing models, discounted cash flow methodologies, or similar techniques and also includes instruments for which the determination of fair value requires significant judgment or estimation.
Revenue Recognition
The Company recognizes revenue under ASC 606, “Revenue from Contracts with Customers.” ASC 606 prescribes a five-step model for recognizing revenue, which includes (i) identifying contracts with customers; (ii) identifying performance obligations; (iii) determining the transaction price; (iv) allocating the transaction price; and (v) recognizing revenue. See Note 4 - Revenue Recognition for further discussion.
Shipping and Handling Costs
Shipping and handling costs charged to customers are recorded as revenue and as cost of goods sold and were approximately $107,000 and $98,000 for the years ended December 31, 2023 and 2022, 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 expense of approximately $44,000 for the year ended December 31, 2023, is primarily a result of losses on foreign currency transactions. 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.
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, 2023 and 2022.
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, 2023 and 2022, 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.
See Note 13 - 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:
Schedule of Antidilutive Securities Excluded from Computation of Earnings Per Share
December 31,
Shares underlying options outstanding 1,789,206 1,365,365
Unvested restricted stock 42,167 -
Foreign Currency Translation
Foreign currency translation is recognized in accordance with ASC 830. The functional currency of Nephros International Limited, the Company’s Irish subsidiary is the Euro, and its translation gains and losses are included in accumulated other comprehensive income. The balance sheet is translated at the year-end rate. The consolidated statements of operations and comprehensive loss are translated at the weighted average rate for the year.
Transactions denominated in a currency other than an entity’s functional currency may give rise to transaction gains and losses. The Company recognizes transaction gains and losses within other (expense) income, net, within the consolidated statements of operations and comprehensive loss.
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.
Segment Reporting
The Company operates in only one business segment from which the Company’s chief operating decision maker evaluates the financial performance of the Company.
Recent Accounting Pronouncements, Not Yet Effective
In December 2023, the FASB issued ASU 2023-09, “Improvements to Income Tax Disclosures,” which enhances the transparency and decision usefulness of income tax disclosures. The guidance is effective for the Company’s annual reporting period ending December 31, 2025. Early adoption is permitted. The Company is assessing the impact of adopting this guidance on its consolidated financial statements.
In November 2023, the FASB issued ASU 2023-07, “Improvements to Reportable Segment Disclosures,” which improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The guidance is effective for the Company beginning in the annual reporting period ending December 31, 2024 and interim periods beginning in fiscal year 2025. Early adoption is permitted. The Company is assessing the impact of adopting this guidance on its consolidated financial statements.
Note 3 - 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.
All discontinued operations relate to the Company’s previously reported PDS segment, for the year ended December 31, 2022.

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. Additionally, the Company evaluated the disposal group including the relevant intangible assets and recorded an impairment loss of $1,395,000. 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.
The following items related to discontinued operations were included in the consolidated statement of cash flows:

Note 4 - Revenue Recognition
The Company recognizes revenue related to product sales when product is shipped via external logistics providers and the other criteria of ASC 606 are met. Product revenue is recorded net of returns and allowances. There was no allowance for sales returns at December 31, 2023 or 2022. In addition to product revenue, the Company recognizes revenue related to royalty and other agreements in accordance with the five-step model in ASC 606.

(1) 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 expired on December 31, 2022, though we and CamelBak thereafter orally agreed to continue operating under the terms of the Sublicense agreement. In March 2024, we entered into a further written amendment to the Sublicense Agreement, which was made effective December 31, 2022, that extended the term of the Sublicense Agreement through December 31, 2025.
Other Revenue - Other revenues are derived from sales of services to customers, which primarily include installation, training and testing on product and equipment sold to certain customers.
Note 5 - 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, 2023 and December 31, 2022, 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, 2023 and December 31, 2022, the fair value measurements of the Company’s assets and liabilities measured on a recurring basis were as follows:

The Company recognized approximately $1.0 million in intangible asset impairment charges during the year ended December 31, 2022, related to the fair value of assets held for sale. (See Note 3-Discontinued Operations).
Goodwill
Goodwill had a carrying value on the Company’s consolidated balance sheets of $0.8 million at December 31, 2023 and 2022, respectively. The Company concluded the carrying value of goodwill was not impaired as of December 31, 2023, or 2022 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 9 - License and Supply Agreement, net
On April 23, 2012, the Company entered into a License and Supply Agreement (as thereafter amended, the “License and Supply Agreement”) with Medica S.p.A. (“Medica”), an Italy-based medical product manufacturing company, for the marketing and sale of certain filtration products based upon Medica’s proprietary Medisulfone ultrafiltration technology in conjunction with the Company’s filtration products, and for an exclusive supply arrangement for the filtration products. Under the License and Supply Agreement, Medica granted to the Company an exclusive license, with right of sublicense, to market, promote, distribute, offer for sale and sell the filtration products worldwide, with certain limitations on territory, during the term of the License and Supply Agreement. In addition, the Company granted Medica an exclusive license under the Company’s intellectual property to make the filtration products during the term of the License and Supply Agreement. The filtration products covered under the License and Supply Agreement include both certain products based on Medica’s proprietary Versatile microfiber technology and certain filtration products based on Medica’s proprietary Medisulfone ultrafiltration technology. In December 2023, the Company signed a new agreement with Medica which extends the term until December 31, 2028, unless earlier terminated by either party in accordance with the terms of the License and Supply Agreement.
In exchange for the license, the gross value of the intangible asset capitalized was $2.3 million. License and supply agreement, net, on the consolidated balance sheet is $0.3 million and $0.4 million as of December 31, 2023 and 2022, respectively.

Net deferred tax assets after valuation allowance $ - $ -
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 decreased approximately $1.1 million from December 31, 2022 to December 31, 2023.
At December 31, 2023, the Company had Federal income tax net operating loss carryforwards of $77.3 million and State income tax net operating loss carryforwards of $6.8 million. The Company had Federal research and development tax credit carryforwards of $1.1 million at December 31, 2023. 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 $14 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 2024 and 2041 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 2018 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 14 - Stock Plans and Share-Based Payments
The fair value of stock options and restricted stock is recognized as stock-based compensation expense in the Company’s consolidated statement of operations and comprehensive loss. The Company calculates stock-based compensation expense in accordance with ASC 718. The fair value of stock-based awards is amortized over the vesting period of the award.

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. 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, 2023.
Schedule of Fair Value Assumptions
Assumption for Option Grants
Stock Price Volatility 72.40 % 75.44 %
Risk-Free Interest Rates 3.71 % 2.74 %
Expected Life (in years) 6.22 5.64
Expected Dividend Yield 0 % 0 %
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 2023 and 2022 is $0.99 and $1.25, respectively. The aggregate intrinsic values of stock options outstanding and stock options vested or expected to vest as of December 31, 2023 was approximately $1.4 million and $0 respectively. A stock option has intrinsic value, at any given time, if and to the extent that the exercise price of such stock option is less than the market price of the underlying common stock at such time. The weighted-average remaining contractual life of options vested or expected to vest as of December 31, 2023 was approximately 6.4 years.
The intrinsic values of stock options exercised was approximately $58,000 for the year ended December 31, 2023. No stock options were exercised for the year ended December 31, 2022.
As of December 31, 2023, there was $0.6 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 2.97 years.
There was no tax benefit related to expense recognized in the twelve months ended December 31, 2023 and 2022, 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 following table summarizes restricted stock activity for the years ended December 31, 2023 and 2022:
Summary of Restricted Stock Activity

The total fair value of restricted stock that vested during the years ended December 31, 2023 and 2022 was approximately $0.2 million and $0.4 million, respectively.
Total stock-based compensation expense for restricted stock was approximately $322,000 and $42,000 for the year ended December 31, 2023 and 2022, respectively and is recognized in selling, general and administrative expenses on the accompanying consolidated statement of operations and comprehensive loss.
Approximately $154,000 of stock compensation expense was recognized in the year ended December 31, 2022 related to restricted stock granted to board members and employees for the year ended December 31, 2023 to settle liabilities for services incurred in the respective prior fiscal year.
As of December 31, 2023, there was approximately $15,000 of unrecognized compensation expense related to restricted stock-based awards granted under the equity compensation plans, which will be amortized over the weighted average remaining requisite service period of 0.4 years. As of December 31, 2022, there was no unrecognized compensation expense related to the restricted stock awards.
The aggregate shares of common stock legally issued and outstanding as of December 31, 2023 is greater than the aggregate shares of common stock outstanding for accounting purposes by the amount of unvested restricted shares.
SRP Equity Incentive Plan
SRP’s 2019 Equity Incentive Plan was approved on May 7, 2019 under which 150,000 shares of SRP’s common stock are reserved for the issuance of options and other awards. This plan is no longer operational, due to the wind down of SRP’s operations and its April 2023 dissolution.
Due to the Company’s deemed acquisition of the non-controlling interest in SRP during the year ended December 31, 2023, all remaining equity-based awards have been forfeited and no further expense will be incurred related to these awards. There were no SRP stock options or other equity awards granted during the year ended December 31, 2023. For the year ended December 31, 2023, a credit of approximately ($27,000) was recognized for expense related to the SRP equity-based awards. Stock-based compensation expense related to the SRP stock grants was approximately $47,000 during the year ended December 31, 2022. Stock-based compensation expense related to the SRP equity-based awards is included in selling, general and administrative expenses on the accompanying consolidated statement of operations and comprehensive loss. Stock-based compensation expense related to the SRP stock options is presented by the Company as noncontrolling interest on the consolidated balance sheet as of December 31, 2022.
Note 15 - Stockholders’ Equity
Noncontrolling Interest
Pursuant to the terms and conditions of a Series A Preferred Stock Purchase Agreement, dated September 9, 2018, among SRP and the purchasers 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 and such purchasers amended the SRP Purchase Agreement to allow for the sale of an additional 100,003 shares of Series A Preferred, all of which were sold on February 4, 2022, for aggregate gross proceeds of $500,015 and otherwise on the same terms and conditions as set forth in the SRP Purchase Agreement. Approximately $188,000 of the proceeds from the February 2022 sales 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 2022 closing included the Company’s Chief Executive Officer, who purchased 313 shares, and Lambda Investors LLC (“Lambda”), an affiliate of Wexford Capital, which together with its affiliates owns approximately 36% of the Company’s common stock, which purchased 25,938 shares of the Series A Preferred in February 2022. Such purchases were made on the same terms as all other purchasers. In addition to the funds provided by the SRP Purchase Agreement, the Company loaned to SRP to the principal amount of $1.3 million, $1.0 million of which was advanced during the year ended December 31, 2020.
As of December 31, 2022, the non-controlling interest in SRP held by holders of the Series A Preferred was classified as equity on the accompanying consolidated balance sheet, as the non-controlling interest is redeemable only upon the occurrence of events that are within the control of the Company. As a result of the adoption of the plan of liquidation and dissolution by SRP’s stockholders and the subsequent filing of a certificate of dissolution of SRP with the State of Delaware, the redemption feature related to the Series A Preferred Stock effectively terminated. As such, the value of the Series A Preferred Stock previously presented in non-controlling interest was reclassified to additional paid in capital as the Company retained control of SRP.
In March 2023, the board of directors of SRP adopted, and the stockholders of SRP approved, a plan to wind down SRP’s operations and dissolve, and in April 2023, SRP filed a certificate of dissolution with the State of Delaware. In accordance with its plan of dissolution, after SRP satisfied its other outstanding liabilities, SRP assigned to the Company all of its remaining assets, including its intellectual property rights, in satisfaction of outstanding indebtedness owed to the Company in the approximate amount of $1.5 million. No other assets are available for distribution to any of SRP’s stockholders, including the Company, in respect of their shares of SRP capital stock, including the Series A Preferred. As a result of the dissolution described above, it was determined approximately $24,000 of inventory likely had no value, and was written off in the period ended March 31, 2023.
Warrants
The Company accounts for stock warrants as either equity instruments or derivative liabilities depending on the specific terms of the warrant agreement. The company had no outstanding warrants at December 31, 2023 and December 31, 2022.
Warrants Exercised During 2022
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.
Note 16 - 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 $91,000 and $104,000 to the SIMPLE IRA in 2023 and 2022, respectively.
