PART I

Item 1.    Business.

Background

The Company is a Delaware corporation, formed in 2005. It operates through operating subsidiaries, including InfuSystem Holdings USA, Inc., a Delaware corporation (“Holdings”), InfuSystem, Inc., a California corporation (“ISI”), First Biomedical, Inc., a Kansas corporation (“First Biomedical”), and IFC, LLC, a Delaware limited liability company (“IFC”).

Business Concept and Strategy

We are a leading national health care service provider, facilitating outpatient care for Durable Medical Equipment manufacturers and health care providers. We provide our products and services to hospitals, oncology practices, ambulatory surgery centers, and other alternate site health care providers. Our headquarters is in Rochester Hills, Michigan, and we operate our business from a total of seven locations in the United States ("U.S.") and Canada.

Our services are provided under a two-platform model. Our lead platform, Integrated Therapy Services (“ITS”), provides the last-mile solution for clinic-to-home healthcare where the continuing treatment involves complex Durable Medical Equipment and services. Our second platform, Durable Medical Equipment Services (“DME Services”), supports our ITS platform and leverages the Company's strong service orientation to win incremental business from our direct payer clients.

We believe InfuSystem has a lot to offer the healthcare community. Over the last 30 plus years, we have developed a unique expertise and service offering that Durable Medical Equipment manufacturers and health care providers are using to reduce costs, improve service, and most importantly, provide welcome options for patients who want to continue their healthcare treatments from home. We perfected our ITS model in oncology and have proven that we can extend this model into other Durable Medical Equipment therapies. Key is the ability to leverage our existing platforms – the new therapies do not require building a new infrastructure; we simply add incrementally to the systems already in place (e.g., sales, clinical, logistics, revenue cycle management, and biomedical services).

ITS is presented as a “turnkey” solution allowing our health care provider customers to focus on the practice of medicine. InfuSystem provides the Durable Medical Equipment and treatment consumables, handles the logistics around orders and deliveries, provides 24x7 nursing support relating to the provided equipment, assumes responsibility for third-party payer Durable Medical Equipment billing, and handles biomedical services (inspection, repair, certification and replacement) for the Durable Medical Equipment. DME Services are provided as a “concierge” offering, whereby InfuSystem leverages its strong service orientation to provide incremental services to our health care provider customers on a direct payer model. DME Services include equipment rental and sales, consumable sales, and biomedical support services.

InfuSystem competes for and retains its business primarily on the basis of its long participation and strong reputation in the Durable Medical Equipment space, its long-standing relationships with Durable Medical Equipment manufacturers and its health care provider customers, and the high levels of service it provides. Current barriers to entry for potential competitors are created by our: (i) growing number of third-party payer networks under contract, which included nearly 800 third-party payer networks as of December 31, 2022, an increase of 4% over the prior year period; (ii) economies of scale, which allow for predictable reimbursement and less costly purchase and management of the pumps, respectively; (iii) established, long-standing relationships as a provider of pumps to outpatient oncology practices in the U.S. and Canada; (iv) our large pump fleet of ambulatory and large volume infusion pumps for rent and for sale, which may allow us to be more responsive to the needs of physicians, outpatient oncology practices, hospitals, outpatient surgery centers, homecare practices, patient rehabilitation centers and patients than a new market entrant; (v) seven geographic locations in the U.S. and Canada that allow for same-day or next-day delivery of pumps; (vi) our growing team of field-based and traveling biomedical technicians; and (vii) a wide array of pump repair and service capabilities. We do not perform any research and development on pumps, but we have made, and continue to make, investments in our information technology.

ITS Segment

The ITS segment’s core purpose is to seek opportunities to grow our business by leveraging our unique know-how in clinic-to-home health care involving Durable Medical Equipment, our logistics and billing capabilities, our growing network of third-party payers under contract, and our clinical and biomedical capabilities. This leverage may take the form of new products and/or services, strategic alliances, joint ventures and/or acquisitions. The leading service within our ITS segment is to supply electronic ambulatory infusion pumps and associated disposable supply kits to private oncology clinics, infusion clinics and hospital outpatient oncology clinics to be utilized in the treatment of a variety of cancers, including colorectal cancer and other

3

disease states (“Oncology Business”). Colorectal cancer is the fourth most prevalent form of cancer in the U.S., according to the American Cancer Society, and the standard of care for the treatment of colorectal cancer relies upon continuous chemotherapy infusions delivered via ambulatory infusion pumps. One of the goals for the ITS segment is to expand into treatment of other types of cancers. In 2022, our Oncology Business approximated 91% of our total ITS segment net revenues. In 2022, we generated approximately 47% of our total ITS segment net revenues from treatments for colorectal cancer and 44% of our ITS segment net revenues from treatments for non-colorectal disease states. There are a number of approved treatment protocols for pancreatic, head and neck, esophageal and other types of cancers, as well as other disease states which present opportunities for growth. There are also a number of other drugs currently approved by the U.S. Food and Drug Administration (the “FDA”), as well as agents in the pharmaceutical development pipeline, which we believe could potentially be used with continuous infusion protocols for the treatment of diseases other than colorectal cancer. Additional drugs or protocols currently in clinical trials may also obtain regulatory approval over the next several years. If these new drugs or protocols obtain regulatory approval for use with continuous infusion protocols, we expect the pharmaceutical companies to focus their sales and marketing efforts on promoting the new drugs and protocols to physicians.

Furthermore, our Oncology Business focuses mainly on the continuous infusion of chemotherapy. Continuous infusion of chemotherapy can be described as the gradual administration of a drug via a small, lightweight, portable infusion pump over a prolonged period of time. A cancer patient can receive his or her medicine anywhere from one to 30 days per month depending on the chemotherapy regimen that is most appropriate to that individual’s health status and disease state. This may be followed by periods of rest and then repeated cycles with treatment goals of progression-free disease survival. This drug administration method has replaced intravenous push or bolus administration in specific circumstances. The advantages of slow continuous low doses of certain drugs are well documented. Clinical studies support the use of continuous infusion chemotherapy for decreased toxicity without loss of anti-tumor efficacy. The 2015 National Comprehensive Cancer Network (“NCCN”) Guidelines recommend the use of continuous infusion for treatment of numerous cancer diagnoses. We believe that the growth of continuous infusion therapy is driven by three factors: evidence of improved clinical outcomes; lower toxicity and side effects; and a favorable reimbursement environment.

The use of continuous infusion has been demonstrated to decrease or alter the toxicity of a number of cytotoxic, or cell killing, agents. Higher doses of drugs can be infused over longer periods of time, leading to improved tolerance and decreased toxicity. For example, the cardiotoxicity (heart muscle damage) of the chemotherapy drug Doxorubicin is decreased by schedules of administration according to The Chemotherapy Source Book by Michael C. Perry. Nausea, vomiting, diarrhea and decreased white blood cell and platelet counts are all affected by duration of delivery. Continuous infusion can lead to improved tolerance and patient comfort while enhancing the patient’s ability to remain on the chemotherapy regimen. Additionally, the lower toxicity profile and resulting reduction in side effects enables patients undergoing continuous infusion therapy to continue a relatively normal lifestyle, which may include continuing to work, going shopping, and caring for family members. We believe that the partnering of physician management and patient autonomy provide for the highest quality of care with the greatest patient satisfaction.

We believe that oncology practitioners have a heightened sensitivity to providing quality service and to their ability to obtain reimbursement for services they provide. Simultaneously, CMS and private insurers are increasingly focused on evidence-based medicine to inform their reimbursement decisions — that is, aligning reimbursement with clinical outcomes and adherence to standards of care. Continuous infusion therapy is a main component of the standard of care for certain types of cancer because clinical evidence demonstrates superior outcomes. Payers’ recognition of this benefit is reflected in their relative reimbursement policies for clinical services related to the delivery of this care.

Additional areas of focus for our ITS segment are as follows:

•Pain Management - providing our ambulatory pumps, products, and services for pain management in the area of post-surgical continuous peripheral nerve block.

•Wound Care - launched in November 2022, the Company established a partnership, SI Wound Care, LLC ("SI Wound Care"), with Sanara MedTech Inc. ("Sanara"). The partnership will focus on delivering a complete wound care solution targeted at improving patient outcomes, lowering the cost of care, and increasing patient and provider satisfaction. The partnership is expected to enable InfuSystem to offer innovative products including Cork Medical LLC’s (“Cork”) negative pressure wound therapy (“NPWT”) devices and supplies and Sanara’s advanced wound care product line to new customers through the jointly controlled entity.

•Acquisitions - we believe there are opportunities to acquire smaller, regional health care service providers, in whole or in part that perform similar services to us but do not have the national market access, network of third-party payer contracts or operating economies of scale that we currently enjoy. We may also pursue acquisition opportunities of companies that perform similar services, but offer different therapies or utilize different devices.

4

•Lymphedema Therapy – Lymphedema therapy includes providing patient care and customer service, pneumatic compression devices and associated garments through our partnership with Bio Compression Systems, Inc. to outpatients, initially targeting our existing acute care and oncology customers, estimated to be 20% of the multi-billion-dollar Lymphedema market.

•Information technology-based services - we also plan to continue to capitalize on key new information technology-based services such as EXPRESS, InfuBus or InfuConnect, Pump Portal, DeviceHub and BlockPain Dashboard®.

The payer environment within our ITS segment is in a constant state of change. We continue to extend our considerable breadth of payer networks under contract as patients move into different insurance coverage plans, including Medicaid and Insurance Marketplace products. In some cases, this may slightly reduce our aggregate billed revenues payment rate but result in an overall increase in collected revenues, due to a reduction in concessions. Consequently, we are increasingly focused on revenues net of concessions.

DME Services Segment

Our DME Services segment’s core service is to: (i) sell or rent new and pre-owned pole-mounted and ambulatory infusion pumps and other Durable Medical Equipment; (ii) sell treatment-related consumables; and (iii) provide biomedical recertification, maintenance and repair services for oncology practices as well as other healthcare site settings, including hospitals, home care and home infusion providers, skilled nursing and acute care facilities, pain centers and others. We purchase new and pre-owned pole-mounted and ambulatory infusion pumps from a variety of sources on a non-exclusive basis. We repair, refurbish and provide biomedical certification for the devices as needed. The pumps are then available for sale, rental or to be used within our ambulatory infusion pump management service. Our acquisition of FilAMed, a privately-held biomedical services company, on January 31, 2021 has supplemented the Company’s existing biomedical recertification, maintenance and repair services for acute care facilities and other alternate site settings including home care and home infusion providers, skilled nursing facilities, pain centers and others. Our acquisition of OB Healthcare Corporation (“OB Healthcare”), a privately-held biomedical services company, on April 18, 2021 further develops and expands InfuSystem’s DME Services segment by adding field service capabilities and complements the Company’s purchase of FilAMed.

Services

ITS Segment

Our core service within our ITS segment is our Oncology Business. After delivering our ambulatory pumps to oncology offices, infusion clinics, and hospital and outpatient chemotherapy clinics, we then directly bill and collect payment from payers and patients for the use of these pumps. At any given time, our pumps are in the possession of these facilities, on a patient, in transit, or in our facilities for cleaning, calibration and storage as reserves for increased demand.

After a physician determines that a patient is eligible for ambulatory infusion pump therapy, the physician arranges for the patient to receive an infusion pump and provides the necessary chemotherapy drugs. The physician and nursing staff train the patient in the use of the pump and initiate service. The physician bills the payers, which may include Medicare, Medicaid, third-party payer companies or patients for the physician’s professional services associated with initiating and supervising the infusion pump administration, as well as the supply of drugs. We directly bill (i) payers, (ii) facilities of our Medicare patients, and (iii) patients for the use of the pump and related disposable supplies. Billing to payers requires coordination with patients and physicians who initiate the service, as physicians’ offices must provide us with appropriate documentation (patient’s insurance information, physician’s order, an acknowledgement of benefits that shows receipt of equipment by the patient, and, in some cases, physician’s progress notes) in order for us to submit a bill to the payers. We provide assistance to uninsured patients that cannot afford our pumps via our financial hardship program – a program that usually matches what our physician practices provide as long as the uninsured patients meet certain criteria. This billing process is handled from our Rochester Hills, Michigan location.

In addition to providing high quality and convenient care, we believe that our business offers significant economic benefits for patients, providers and payers.

•Our clinical support team employs oncology, pain, Intravenous Certified, and Oncology Certified registered nurses trained on ambulatory infusion pump equipment who staff our 24x7 customer service hotline to address questions that patients may have about their pump treatment, the infusion pumps or other medical or technical questions related to the pumps.

5

•Physicians use our services to outsource the capital commitment, pump service, maintenance and billing and administrative burdens associated with pump ownership. Our services also allow the doctor to continue a direct relationship with the patient and to receive professional service fees for setting up the treatment and administering the drugs.

•We provide methods for the physician offices to deliver the appropriate paperwork for billing through a number of electronic means including EXPRESS and InfuConnect reducing the required effort on the employees of the physician offices.

•We believe our services are attractive to payers because such services are generally less expensive than hospitalization or standalone home health care.

Also, within ITS, we offer pain management services via electronic ambulatory infusion pumps for post-operative pain management using our pumps along with a numbing agent and a continuous nerve block catheter – continuous peripheral nerve block (“CPNB”). Using CPNB for the management of post-operative pain, which usually lasts two to three days after surgery, can result in reduced pain for the patient, increased satisfaction scores for the surgical center or hospital, and reduced need for post-operative opioid pain medication. These services include our patient care call center interaction offering support to patients and the review and collection of pain score patient outcome data for outpatient surgery centers using our proprietary BlockPain Dashboard®.

DME Services Segment

Other services we offer are classified under our DME Services segment and include the rental, sale or leasing and servicing of pole-mounted and ambulatory infusion pumps to oncology practices, hospitals and other clinical settings. These pumps are available for daily, weekly, monthly or annual rental periods. We also sell treatment consumables that can be used in conjunction with the pumps we sell and rent.

In addition to sales, rental and leasing services, we also provide biomedical maintenance, repair and certification services for the devices we offer as well as for devices owned by customers but not acquired from us. We operate pump service and repair “Centers of Excellence” from all of our locations across the U.S. and Canada and employ a staff of highly-trained technicians to provide these services. Our main Center of Excellence for service is our Lenexa, Kansas facility. In addition to the maintenance and repair services we perform at these facilities, we offer similar services that can be performed directly at our customer locations nation-wide through our team of field-based and traveling biomedical technicians.

As of December 31, 2022, our rental fleet of pole-mounted pumps, ambulatory pumps and NPWT medical equipment for both our ITS and DME Services segments had a historical cost of $99.2 million, up from $91.9 million at the end of 2021, and included approximately 125 makes and models of equipment dedicated to our rental services. Additionally, as of December 31, 2022 and 2021, we had a fleet of new and used pole-mounted pumps, ambulatory pumps and NPWT medical equipment with a historical cost of $2.8 million and $1.8 million, respectively, for sale or rental.

Information Technology

Our Information Technology (“IT”) department is focused on not only supporting our internal IT infrastructure needs, but also supporting our revenue cycle management infrastructure including our electronic medical record technology (“EMR”) that allows medical facilities to use our infusion pumps and services via our solutions such as EXPRESS and InfuConnect. This focus has enabled current billing information to be transferred to us from participating facilities electronically and automatically. Our focus on IT solutions resulted in the development of EXPRESS, a product powered by our InfuBus data integration platform, and provides for paperless delivery of the appropriate information for InfuSystem to bill payers that:

•eliminates all paper;

•provides an enhanced visibility as a result of real time status and reporting;

•reduces risk of error;

•automates treatment logs, pump assignments, tracking and physician’s orders;

•provides a secure scanner for easy pump assignment to patients; and

•removes interruptions from physician practices’ daily schedules, and standardizes data flow for clinics and hospitals with multiple locations.

Relationships with Physician Offices

As of December 31, 2022, we had business relationships with clinical oncologists in over 2,150 outpatient oncology clinics. Although this represents a substantial number of the oncologists in the U.S., we believe that we can continue to expand

6

our network to further penetrate the oncology market. Based on our retention rates and the positive results of our professional customer satisfaction research, we believe our relationships with physician offices are strong.

We believe that, in general, we do not compete directly with hospitals and physician offices to treat patients. Rather, by providing products and services to hospitals and physician offices and other care facilities and providers, we believe that we assist other providers in meeting increasing patient demand and managing institutional constraints on capital and manpower due to the nature of limited resources in hospitals and physician offices.

Physician practices in the oncology field are following the overall healthcare practices trend to consolidate. However, as of December 31, 2022, we had gained more facilities than we had lost. We expect this trend to continue for the foreseeable future.

Employees

As of December 31, 2022, we had 438 employees, including 420 full-time employees and 18 part-time or contract employees. None of our employees are unionized.

Material Suppliers

We supply a wide variety of pumps and associated equipment, as well as disposables and ancillary supplies. The majority of our pumps are electronic infusion pumps. Smiths Medical, Inc. and Moog Medical Devices Group each supplied more than 10% of the ambulatory pumps purchased by us in 2022. The Company has a supply agreement in place with each of these suppliers. Certain “spot” purchases are made on the open market subject to individual negotiation. We also supply NPWT medical equipment, as well as related disposables and ancillary supplies.

Seasonality

Revenues may be seasonal due to the impact of co-pays and deductibles for patients’ insurance that traditionally reset each January. This has been further impacted by changes in the insurance industry as it responds to increased government regulation. Also, rental customers tend to make buy versus rent decisions late in the year as customer capital budgets are being finalized, impacting sales revenue in the second half of the year, predominantly in the fourth quarter. Furthermore, as the Company’s liquidity has improved, opportunistic pump purchases are made from time to time. These opportunistic pump purchases also allow for opportunistic pump sales, which could be material. The timing of such purchases and sales vary within the course of a year.

Environmental Laws

We are required to comply with applicable federal, state and local environmental laws regulating the disposal of cleaning agents used in the process of cleaning medical equipment, as well as the disposal of sharps and blood products used in connection with the pumps and medical equipment. We do not believe that compliance with such laws has a material effect on our business.

Significant Customers

We have sought to establish contracts with as many third-party payer organizations as commercially practicable, in an effort to ensure that reimbursement is not a significant obstacle for providers who recommend continuous infusion therapy and wish to utilize our services. A third-party payer organization is a health care payer or a group of medical services payers that contracts to provide a wide variety of health care services to enrolled members through participating providers such as us. A payer is any entity that pays on behalf of a member patient.

As of December 31, 2022, we had contracts with nearly 800 third-party payer networks, an increase of 4% over the prior year period. Material terms of contracts with third-party payer organizations are typically a pre-negotiated fee schedule rate or a then-current proprietary fee schedule rate for equipment and supplies provided. The majority of these contracts generally provide for a term of one year, with automatic one-year renewals, unless we or the contracted payer elect not to renew. We also contract with various other third-party payer organizations, Medicaid, commercial Medicare replacement plans, self-insured plans, facilities of our Medicare patients and numerous other insurance carriers. No single payer or customer represented more than 10% of net revenue in 2022, 2021 or 2020.

Competitors

We believe that our competition primarily consists of national, regional, and hospital-owned Durable Medical Equipment providers and service companies, physician providers and home care infusion providers and the competitive products and services they offer. An estimate of the number of competitors is not known or reasonably available, due to the wide variety in type and size of the market participants described below. We are not aware of any industry reports with respect to the competitive market described below. The description of market segments and business activities within those market segments is based on our experiences in the industry.

•National Durable Medical Equipment Providers and Service Companies: Other national providers and service companies have offerings similar to us. These products and service offerings include, but are not limited to, third-party reimbursement, direct rental and sale of infusion electronic and disposal pumps and related products and services for patients in the home, oncology clinics, ambulatory surgery centers, hospitals and other sites of care.

•Regional Durable Medical Equipment Providers: Regional Durable Medical Equipment providers act as distributors for a variety of medical products. We believe regional Durable Medical Equipment provider sales forces generally consist of a relatively small number of salespeople, usually covering several states. Regional Durable Medical Equipment providers tend to carry a limited selection of infusion pumps and their salespeople generally have limited resources. Regional Durable Medical Equipment providers usually do not have 24x7 nursing services. We believe that Regional Durable Medical Equipment providers have relatively few third-party payer contracts, which may prevent these providers from being paid at acceptable levels and may also result in higher out-of-pocket costs for patients.

•Hospital-Owned Durable Medical Equipment Providers: Many hospitals have in-house Durable Medical Equipment providers to supply basic equipment. In general, however, these providers have limited capital and tend to stock a small inventory of infusion pumps. We believe that hospital-owned providers have limited ability to grow because of limited patient populations. Growth from outside of the hospital may pose a challenge because hospitals typically will not provide referrals to competitors, instead preferring to offer patients a choice of non-hospital-affiliated Durable Medical Equipment providers.

•Physician Providers: A limited number of physicians maintain an inventory of their own infusion pumps and provide them to patients for a fee. However, we believe that pump utilization in this area tends to be low and the costs associated with ongoing supplies, preventative maintenance and repairs can be relatively high. Moreover, we believe that a high percentage of Durable Medical Equipment claims by doctors are rejected by payers upon first submission, requiring a physician’s staff to spend significant time and effort to resubmit claims and receive payment for treatment. The numerous service and technical questions from patients may present another significant cost to a physician provider’s staff.

•Home Care Infusion Providers: Home care infusion providers provide chemotherapy drugs and services to allow for in-home patient treatment. We believe that home care infusion treatment can be very costly and that many patients do not carry insurance coverage that pay for home-based infusion services, resulting in larger out-of-pocket costs. Because home care treatments may take as long as six months, these costs can be high and can result in higher patient co-payments. We believe that home care providers may also be reluctant to offer 24x7 coverage or additional patient visits, due to capped fees.

Regulation of Our Business

Our business is subject to various regulations. Specifically, as a registered Medicare supplier of Durable Medical Equipment and related supplies, we must comply with supplier standards established by CMS regulating Medicare suppliers of Durable Medical Equipment, Prosthetics, Orthotics and Supplies (“DMEPOS Supplier Standards”). The DMEPOS Supplier Standards consist of 30 requirements that must be met in order for a DMEPOS supplier to be eligible to receive payment for a Medicare-covered item. Some of the more significant DMEPOS Supplier Standards require us to (i) advise Medicare beneficiaries of their option to purchase certain equipment, (ii) honor all warranties under state law and not charge Medicare beneficiaries for the repair or replacement of equipment or for services covered under warranty, (iii) permit CMS agents to conduct on-site inspections to ascertain compliance with the DMEPOS Supplier Standards, (iv) maintain liability insurance in prescribed amounts, (v) refrain from contacting Medicare beneficiaries by telephone, except in certain limited circumstances, (vi) answer questions and respond to complaints of beneficiaries regarding the supplied equipment, (vii) disclose the DMEPOS Supplier Standards to each Medicare beneficiary to whom we supply equipment, (viii) maintain a complaint resolution procedure and record certain information regarding each complaint, (ix) maintain accreditation from a CMS approved accreditation organization, and (x) meet certain specified surety bond requirements.

8

We are also subject to the provisions of the Health Insurance Portability and Accountability Act of 1996 (“HIPAA”), which are designed to protect the security and confidentiality of certain protected health information. Under HIPAA, we must provide patients access to certain records and must notify patients of our use of protected health information and patient privacy rights. Moreover, HIPAA sets limits on how we may use individually identifiable health information and prohibits the use of patient information for marketing purposes. The adoption of the American Recovery and Reinvestment Act of 2009 (“ARRA”) includes a new breach notification requirement that applies to breaches of unsecured health information occurring on or after September 23, 2009. We are subject to regulations in the various states in which we operate. We believe we are in material compliance with all such regulations.

Item 1A.    Risk Factors.

An investment in our securities involves a high degree of risk. You should consider carefully all of the material risks described below, together with the other information contained in this Form 10-K. If any of the following events occur, our business, financial condition, results of operations and cash flows may be materially adversely affected.

RISK FACTORS RELATING TO OUR BUSINESS AND THE INDUSTRY IN WHICH WE OPERATE

Our business is substantially dependent on third-party reimbursement. Any change in the overall health care reimbursement system may adversely impact our business.

Our revenues are substantially dependent on third-party reimbursement. We are paid directly by private insurers and, in some cases, governmental agencies, often on a fixed fee basis, for the use of continuous infusion equipment and related disposable supplies provided to patients. If the average fees allowable by private insurers or governmental agencies were reduced, the negative impact on revenues could have a material effect on our business, financial condition, results of operations and cash flows. Also, if amounts owed to us by patients and insurers are reduced or not paid on a timely basis, we may be required to increase our concessions and/or decrease our revenues.

Changes in the health care reimbursement system often create financial incentives and disincentives that encourage or discourage the use of a particular type of product, therapy or clinical procedure. Such changes may be impacted by the growth in ACOs, reduction of providers by payers, the use of lower cost rental networks and other factors. Market acceptance of continuous infusion therapy may be adversely affected by changes or trends within the health care reimbursement system. Changes to the health care reimbursement system that favor other technologies or treatment regimens that reduce reimbursements to providers or treatment facilities, including increasing competitive pressures from home health care and other companies that use our services, may adversely affect our ability to market our services profitably. Overall, such dependency and potential changes could materially and adversely affect our business, financial condition, results of operations and cash flows.

Our business is substantially dependent on estimates of collectible revenue from third-party reimbursement.

Our revenues are substantially dependent on estimates of collectible revenue from third-party reimbursement. Due to the complex nature of third-party reimbursement for the use of continuous infusion equipment and related disposable supplies provided to patients, we must estimate, based upon historical averages, the amount of collectible revenue that may be derived from each patient treatment. If average reimbursement rates diverge from historical levels, the estimates of such revenue may diverge from actual collections.

We utilize statistical methods to account for such changes, but there can be no assurance that the revenue reported in any period will ultimately be collected. Any recognized revenue related to third-party reimbursement from prior periods, which remains uncollected until written off from accounts receivable, will negatively impact revenues in the period in which it is written off. Thus, over time, recognized revenue net of concessions will approximate total collections.

9

The loss of a relationship with one or more third-party payers could negatively impact our business.

Our contracts for reimbursement with third-party payers are often for a term of one year, with automatic one-year renewals, unless we or the contracted payer elect not to renew. These evergreen contracts are subject to termination upon written notice. One or more terminations could have a material and adverse effect on our business, financial condition, results of operations and cash flows.

Any federal government shutdown may adversely impact our business.

Our revenues are dependent on private insurers and governmental agencies. In the absence of any bipartisan agreement in the federal government with respect to payments from governmental agencies, our revenues could be reduced. In addition, any federal government shutdown could also have a material and adverse impact on our business, financial condition, results of operations and cash flows.

Payer concentration may adversely impact our business.

As of December 31, 2022, we had contracts with nearly 800 third-party payer networks, an increase of 4% over the prior year period. Material terms of contracts with third-party payer organizations are typically a pre-negotiated fee schedule rate or a then-current proprietary fee schedule rate for equipment and supplies provided. The majority of these contracts generally provide for a term of one year, with automatic one-year renewals, unless we or the contracted payer elect not to renew. We also contract with various other third-party payer organizations, Medicaid, commercial Medicare replacement plans, self-insured plans, facilities of our Medicare patients and numerous other insurance carriers. No single payer represented more than 10% of net revenue in 2022, 2021 or 2020. To the extent such dependency was to occur, significant fluctuations in revenues, results of operations and liquidity could arise if any significant contracted payer reduces its reimbursement for the services we provide.

Our billing process is dependent on meeting payer claims processing guidelines which are subject to change at the discretion of the payers. Such changes would materially impact our ability to bill and the timing of such billings, which could materially and adversely impact our net revenues and cash flows, which impact would be even greater if such changes are made by one of our larger payers.

The continued consolidation of physician practices, outpatient infusion clinics, oncology clinics, homecare providers and hospitals, increases the concentration of decision makers whom either choose to use our ambulatory electronic pumps within our Oncology Business or directly rent, lease or purchase pumps or supplies from us.

While we make every effort to benefit from such concentration, it could materially and adversely affect our business, financial condition, results of operations and cash flows.

Increased focus on early detection and diagnostics may adversely affect our business.

An increased focus on lowering health care spending via improved diagnostic testing (i.e., defensive medicine) and patient monitoring could materially and negatively affect our business. A large portion of our ambulatory infusion pumps are dedicated to a specific form of cancer (i.e., colorectal). As a result of rising health care costs, there may be a demand for more cost-effective approaches to disease management, specifically for colorectal cancer, as well as for emphasis on screening and accurate diagnostic testing to facilitate early detection of potentially costly, severe afflictions. Any change in the approach to treatment of colorectal cancer could have a material and adverse impact on our business, financial condition, results of operations and cash flows.

If future clinical studies demonstrate that oral medications or other therapies that do not use our electronic ambulatory pumps are at least as effective as continuous infusion therapy, our business could be adversely affected.

Ongoing clinical trials are currently evaluating and comparing the therapeutic benefits of current continuous infusion-based regimens with various oral medication regimens. If these clinical trials demonstrate that oral medications provide equal or greater therapeutic benefits and/or demonstrate reduced side effects compared to prior oral medication regimens, our revenues and overall business could be materially and adversely affected. Additionally, if new oral medications or other therapies that do not utilize our ambulatory electronic pumps are introduced to the market that are superior to existing oral therapies, physicians’ willingness to prescribe continuous infusion-based regimens could decline, which would materially and adversely affect our business, financial condition, results of operations and cash flows.

10

Our success is impacted by the availability of the chemotherapy drugs that are used in our continuous infusion pump systems.

We primarily derive our revenues from the rental of ambulatory infusion pumps to oncology patients through physicians’ offices and chemotherapy clinics. A shortage in the availability of chemotherapy drugs that are used in the continuous infusion pump system, which has occurred in the past, could have a material and adverse effect on our business, financial condition, results of operations and cash flows.

We are dependent on our Medicare Supplier Number.

We are required to have a Medicare Supplier Number in order to have the ability to bill Medicare for services provided to Medicare patients. Furthermore, all third-party and Medicaid contracts require us to have a Medicare Supplier Number. We are required to comply with Medicare DMEPOS Supplier Standards in order to maintain such number. If we are unable to comply with the relevant standards, we could lose our Medicare Supplier Number. Without such number, we would be unable to continue our various third-party and Medicaid contracts. A significant portion of our revenues are dependent upon our Medicare Supplier Number, the loss of which would materially and adversely affect our business, financial condition, results of operations and cash flows.

The CMS requires that all Durable Medical Equipment providers must be accredited by a CMS-approved accreditation organization. On February 17, 2009, we initially received accreditation from CHAP, and we have remained accredited to date. If we lost our accredited status, our business, financial condition, revenues and results of operations would be materially and adversely affected.

The impact of U.S. health care reform legislation on us remains uncertain.

The ACA has perpetuated the development of alternative provider payment models by CMS and the major national commercial payers. These payment models do not replace the current fee-for-service models nor replace current payer contracts, but rather provide additional financial incentives to certain “accountable” providers to improve quality and lower cost. The implications for the Company will come from the provider networks that are forming in order to integrate and coordinate care under these alternative models with CMS and the commercial payers. These provider networks include ACOs, patient-centered primary care medical homes, specialty medical homes, networks accepting bundled payment programs, and other “performance” networks that contract with CMS and commercial payers under alternative payment models that financially reward improved quality and lower medical cost. The relationship between us and our provider practices and facilities that are participating in these provider networks under alternative payment models will depend on (i) the extent to which these provider networks give priority to the medical cost associated with our Durable Medical Equipment services and (ii) whether our services are seen as part of a care delivery model that delivers higher value – higher quality at a lower cost.

Our failure to perform under these alternative payment models, or under similar models or conditions introduced by future legislation, could have a material adverse impact on our business, financial condition, results of operations and cash flows.

We rely on independent suppliers for our products. Any delay or disruption in the supply of products, particularly our supply of electronic ambulatory pumps, may negatively impact our operations.

Our infusion pumps and related consumables are obtained from outside vendors. The majority of our new pumps are electronic infusion pumps which are supplied to us by two major suppliers: Smiths Medical, Inc. and Moog Medical Devices Group. The loss or disruption of our relationships with outside vendors, including pumps, parts, or supply recall or pump end-of-life announcements or availability of related proprietary consumable supplies, could subject us to substantial delays in the delivery of pumps or services provided to customers. From time to time, we or our suppliers may experience supply chain disruptions due to circumstances beyond our or our suppliers’ control, such as the 2020 outbreak of COVID-19. Significant delays in the delivery or service of pumps or related proprietary consumable supplies could result in possible cancellation of orders and the loss of customers. Our inability to provide pumps to meet delivery schedules could have a material adverse effect on our reputation in the industry, as well as on our business, financial condition, results of operations and cash flows.

We face periodic reviews and billing audits from governmental and private payers and these audits could have adverse results that may negatively impact our business.

As a result of our participation in the Medicaid program and our registration in the Medicare program, we are subject to various governmental reviews and audits to verify our compliance with these programs and applicable laws and regulations. We also are subject to audits under various government programs in which third-party firms engaged by CMS conduct extensive

11

reviews of claims data and medical and other records to identify potential improper payments under the Medicare program. Private pay sources also reserve the right to conduct audits. If billing errors are identified in the sample of reviewed claims, the billing error can be extrapolated to all claims filed which could result in a larger overpayment than originally identified in the sample of reviewed claims. Our costs to respond to and defend reviews and audits may be significant and could have a material adverse effect on our business, financial condition, results of operations and cash flows. Moreover, an adverse review or audit could result in:

•required refunding or retroactive adjustment of amounts we have been paid by governmental or private payers;

•state or Federal agencies imposing fines, penalties and other sanctions on us;

•loss of our right to participate in the Medicare program, state programs, or one or more private payer networks; or

•damage to our business and reputation in various markets.

Any one of these results could have a material adverse effect on our business, financial condition, results of operations and cash flows.

Our failure to maintain controls and processes over billing and collecting could have a significant negative impact on our Consolidated Financial Statements.

The collection of accounts receivable is a significant challenge and requires constant focus and involvement by management and ongoing enhancements to information systems, billing center operating procedures and proper staffing levels. If we are unable to properly bill and collect our accounts receivable, our results could be materially and adversely affected. While management believes that our staffing, controls and processes are satisfactory, there can be no assurance that accounts receivable collectability will remain at current levels.

State licensure laws for Durable Medical Equipment suppliers are subject to change. If we fail to comply with any state laws, we will be unable to operate as a Durable Medical Equipment supplier in such state and our business operations will be adversely affected.

As a Durable Medical Equipment supplier operating in all 50 states, we are subject to each state’s licensure laws regulating Durable Medical Equipment suppliers. State licensure laws for Durable Medical Equipment suppliers are subject to change and we must ensure that we are continually in compliance with the laws of all 50 states. In the event that we fail to comply with any state’s laws governing the licensing of Durable Medical Equipment suppliers, we will be unable to operate as a Durable Medical Equipment supplier in such state until we regain compliance. We may also be subject to certain fines and/or penalties and our business operations could be materially and adversely affected.

Our customer concessions may not be adequate to cover actual losses.

Our third-party payer contracts do not guarantee annual inflationary increases, typical of the Durable Medical Equipment payer contracting environment. Contracted reimbursement rates are either subject to increases or decreases in CMS program rates or, if not indexed to government rates, are frozen until those payer contracts are reopened and renegotiated. While we monitor reimbursement levels to identify specific payer reimbursement rates that have eroded and renegotiate such rates, we may not be able to maintain or improve overall reimbursement levels, thereby compromising the adequacy of the predicted customer concessions.

We may also face reduced reimbursements from private third-party payers. In addition, our customers may be unable to make timely payments to us. Although we maintain allowances for estimated losses resulting from the inability of our customers to make required payments, we cannot guarantee that we will continue to experience the same loss rates that we have in the past. If we begin to experience an increase in our loss rates in excess of our allowances, it could materially and adversely impact our business, financial condition, results of operations and cash flows.

Our growth strategy includes expanding into treatment for cancers other than colorectal cancer. There can be no assurance that continuous infusion-based regimens for these other cancers will become standards of care for large numbers of patients or that we will be successful in penetrating these different markets.

An aspect of our growth strategy is to expand into the treatment of other cancers, such as head, neck and gastric cancers. This population of patients will expand only if clinical trial results for new drugs and new combinations of drugs demonstrate superior outcomes for regimens that include continuous infusion therapy relative to alternatives. No assurances can be given that these new drugs and drug combinations will be approved or will prove superior to oral medication or other treatment

12

alternatives. In addition, no assurances can be given that we will be able to penetrate successfully any new markets that may develop in the future or manage the growth in additional resources that would be required.

The industry in which we operate is intensely competitive and ever-changing. If we are unable to successfully compete with our competitors, our business operations may suffer.

The drug infusion industry is highly competitive. Some of our competitors and potential competitors, including some of the practices that we service, have significantly greater resources than we do for information technology, marketing and sales. As a result, they may be better able to compete for market share, even in areas in which our services may be superior. The industry is subject to technological changes and such changes may put our current fleet of pumps, smart pump licensing, our information technology solutions or our other technological-based solutions at a competitive disadvantage. Furthermore, the healthcare industry, in general, is experiencing market consolidation, reducing the number of decision makers. If we are unable to effectively compete in our market, our business, financial condition, results of operations and cash flows may be materially and adversely affected.

Our industry is dependent on regulatory guidelines that affect our billing practices. If our competitors do not comply with these regulatory guidelines, our business could be adversely affected.

Aggressive competitors may not fully comply with rules regarding CMS and other payers’ billing and documentation requirements. Competitors, who do not meet the same standards of compliance that we do with respect to billing regulations, may put us at a potential competitive disadvantage. We are a participating provider with Medicare and as of December 31, 2022, we were under contract with nearly 800 third-party payer networks, all of which have very stringent guidelines. If our competitors do not comply with these regulatory guidelines, we could be put at a potential competitive disadvantage and our business, financial condition, results of operations and cash flows could be material and adversely affected.

Although we do not manufacture the products we distribute, if one of the products distributed by us proves to be defective or is misused by a health care practitioner or patient, we may be subject to liability that could adversely affect our financial condition and results of operations.

Although we do not manufacture the pumps that we distribute, a defect in the design or manufacture of a pump distributed or serviced by us, or a failure of pumps distributed by us to perform for the use specified, could have a material and adverse effect on our reputation in the industry and subject us to claims of liability for injuries and otherwise. Misuse of the pumps distributed by us by a practitioner or patient that results in injury could similarly subject us to liability. Any substantial underinsured loss could have a material and adverse effect on our business, financial condition, results of operations and cash flows. Furthermore, any impairment of our reputation could have a material and adverse effect on our revenues and prospects for future business.

We intend to continue to pursue opportunities for the further expansion of our business through strategic alliances and/or joint ventures. Future strategic alliances and/or joint ventures may require significant resources and/or result in significant unanticipated costs or liabilities to us.

We intend to continue to pursue opportunities for the further expansion of our business through strategic alliances and/or joint ventures. Any future strategic alliances or joint ventures will depend on our ability to identify suitable partners, negotiate acceptable terms for such transactions and obtain financing, if necessary. These investments require significant managerial attention, which may be diverted from our other operations.

If we engage in strategic acquisitions, we may experience significant costs and difficulty in assimilating operations or personnel, which could threaten our future growth.

If we make any acquisitions, we could have difficulty assimilating operations, technologies and products and services. In addition, we could have difficulty integrating or retaining personnel and maintaining employee morale as we take steps to combine the personnel and business cultures of separate organizations into one and to eliminate duplicate positions and functions. It may also be difficult for us to preserve important relationships with others, such as strategic partners, customers, and suppliers, who may delay or defer decisions on agreements with us, or seek to change existing agreements with us, because of the acquisition. In addition, acquisitions may involve entering markets in which we have no or limited direct prior experience. The occurrence of any one or more of these factors could disrupt our ongoing business, distract our management’s and employees’ attention from our ongoing business operations, result in decreased operating performance and increase our expenses. Moreover, our profitability may suffer because of acquisition-related costs or amortization of intangible assets. Furthermore, we may have to incur debt or issue equity securities in future acquisitions. The issuance of equity securities would dilute our existing stockholders.

13

We may be unable to maintain adequate working relationships with health care professionals.

We seek to maintain close working relationships with respected physicians and medical personnel in hospitals and universities. We rely on these professionals to assist us in the development of proprietary service and improvements to complement and expand our existing service and product lines. If we are unable to maintain these relationships, our ability to market and sell new and improved products and services could decrease and future operating results could be unfavorably affected.

If we fail to comply with applicable governmental or accrediting bodies’ regulations, we could face substantial penalties and our business, operations and financial condition could be adversely affected.

Certain federal, state health care, and accreditation bodies’ laws and regulations, including those pertaining to fraud and abuse and patients’ rights, are applicable to our business. The laws that are applicable to our business include:

•the federal health care program Anti-Kickback Statute, which prohibits, among other things, soliciting, receiving or providing remuneration, directly or indirectly, to induce (i) the referral of an individual, for an item or service or (ii) the purchasing or ordering of a good or service, for which payment may be made under federal health care programs such as the Medicare and Medicaid programs;

•federal false claims laws which prohibit, among other things, knowingly presenting, or causing to be presented, claims for payment from Medicare, Medicaid, or other third-party payers that are false or fraudulent, and which may apply to entities like us that promote medical devices, provide medical device management services and may provide coding and billing advice to customers;

•HIPAA, which prohibits executing a scheme to defraud any health care benefit program or making false statements relating to health care matters and which also imposes certain requirements relating to the privacy, security and transmission of individually identifiable health information; and

•state law equivalents of each of the above federal laws, such as anti-kickback and false claims laws that may apply to items or services reimbursed by any third-party payer, including commercial insurers, and state laws governing the privacy and security of health information in certain circumstances, many of which differ in significant ways from state to state and often are not preempted by HIPAA, thus complicating compliance efforts.

If our operations are found to be in violation of any of the laws described above or any other regulations that apply to us, we may be subject to penalties, including civil and criminal penalties, damages, fines and the curtailment or restructuring of our operations. Any penalties, damages, fines, curtailment or restructuring of our operations could materially and adversely affect our business, financial condition, results of operations and cash flows. Any action against us for violation of these laws, even if we successfully defend against it, could cause us to incur significant legal expenses and divert our management’s attention from the operation of our business. Moreover, achieving and sustaining compliance with applicable federal and state privacy, security and fraud laws may prove costly.

Failure to protect our intellectual property could substantially harm our business and operating results.

In order to protect our trade secrets and other confidential information, we rely in part on confidentiality agreements with our employees, consultants and third parties with whom we have relationships. These agreements may not effectively prevent disclosure of trade secrets and other confidential information and may not provide an adequate remedy in the event of misappropriation of trade secrets or any unauthorized disclosure of trade secrets and other confidential information. In addition, others may independently discover our trade secrets and confidential information and, in such cases, we could not assert any trade secret rights against such parties. Costly and time-consuming litigation could be necessary to enforce or determine the scope of our trade secret rights and related confidentiality and nondisclosure provisions. Failure to obtain or maintain trade secret protection, or our competitors' acquisition of our trade secrets, could materially and adversely affect our competitive business position.

Covenants in our current and any future debt agreements restrict our business.

Our 2021 Credit Agreement contains and the agreements that govern our future indebtedness may contain, covenants that restrict our ability to and the ability of our subsidiaries to, among other things:

•engage in a transaction that results in a change of control, as defined by the 2021 Credit Agreement;

•create, incur, assume or suffer to exist any lien upon any of our property, assets or revenues;

•make certain investments or acquisitions;

14

•create, incur, assume or suffer to exist certain indebtedness;

•merge, dissolve, liquidate, consolidate or sell all or substantially all of our assets;

•make any disposition or enter into any agreement to make any disposition;

•repurchase outstanding stock from the open market; and

•declare or make, directly or indirectly, any dividend or other restricted payment, or incur any obligation (contingent or otherwise) to do so.

These covenants may restrict our ability to operate our business. Our failure to comply with these covenants could result in an event of default that, if not cured or waived, could result in reduced liquidity for the Company and could have a material and adverse effect on our ability to operate our business, financial condition, results of operations and cash flows. Additionally, our ability to pay interest and repay the principal for our indebtedness is dependent upon our ability to manage our business operations, generate sufficient cash flows to service such debt and the other factors discussed in this section. Our 2021 Credit Agreement also contains certain financial covenants. As of December 31, 2022, we were in compliance with all the covenants contained in the 2021 Credit Agreement, however, there can be no assurance that we will be able to manage any of the risks associated with debt agreements successfully.

Economic uncertainty or economic deterioration could adversely affect us.

There continues to be global economic uncertainty, as well as increased inflation, heightened interest rates and a recessionary environment. Ongoing political changes and conflicts in the U.S. and abroad continue to contribute to global economic uncertainty and volatility in the global financial markets. In February 2022, Russian forces launched significant military actions against Ukraine, which has caused significant international conflict, including sanctions, tensions and military actions. In addition, the effects of the COVID-19 pandemic have contributed to economic uncertainty. Continued economic uncertainty may continue to drive stock market and interest rate volatility, increased inflation and adversely impact consumer confidence, product demand, and our ability to refinance our debt. Economic conditions, along with our operating performance, may also materially and adversely impact our ability to access the financial markets. Accordingly, our future business and financial results are subject to uncertainty. If economic conditions deteriorate in the future, our future revenues and financial results could be materially and adversely affected.

Changes in tax laws or challenges to our tax positions could adversely affect our business, results of operations and financial condition.

We are subject to income taxes as well as non-income based taxes in federal and various state jurisdictions. Changes in tax laws, including, for example, those resulting from the U.S. federal tax legislation commonly referred to as the Coronavirus Aid, Relief, and Economic Security (CARES) Act, as well as other factors, could cause us to experience fluctuations in our tax obligations and effective tax rates in future periods and otherwise adversely affect our tax positions and/or our tax liabilities. The full impact of the CARES Act on us may change significantly as regulations, interpretations and rulings relating to the CARES Act are issued and additional changes in U.S. federal and state tax laws are made in the future. There can be no assurance that our effective tax rates, tax payments, tax credits or incentives will not be adversely affected by these or other initiatives.

We are subject to audits by tax authorities from time to time in federal and state jurisdictions. Tax authorities may disagree with certain positions we have taken and assess additional taxes and penalties. We regularly assess the likely outcomes of these audits in order to determine the appropriateness of our tax provision. However, there can be no assurance that we will accurately predict the outcomes of these audits, and the actual outcomes of these audits could have a material impact on our results of operations.

The value of our net operating loss carryforwards may become impaired if we do not generate sufficient future taxable income required to utilize all or a portion of our net operating loss carryforwards prior to their expiration.

The Company’s U.S. federal net operating loss carryforward for tax purposes was $35.7 million at December 31, 2022, resulting in a federal deferred tax asset of $7.5 million. Approximately $29.1 million of the Company’s U.S. federal net operating loss carryforwards will begin to expire in various years beginning in 2031. The Company’s realization of its deferred tax assets including the loss carryforwards is dependent upon many factors, including, but not limited to, the Company’s ability to generate sufficient taxable income in sufficient amounts. There can be no assurance that we will generate the required amounts of taxable income before the expiration dates are reached.

RISK FACTORS RELATING SPECIFICALLY TO OUR COMMON STOCK

The market price of our common stock has been, and is likely to remain, volatile, subject to low trading volume and may decline in value.

The market price of our common stock has been and may continue to be volatile. Market prices for securities of health care services companies, including ours, have historically been volatile, and the market has from time to time experienced significant price and volume fluctuations that appear unrelated to the operating performance of particular companies. The following factors, among others, can have a significant effect on the market price of our common stock:

•announcements of technological innovations, new products, or clinical studies by others;

•government regulation;

The realization of any risks described in these “Risk Factors” could also have a negative effect on the market price of our common stock.

We do not pay dividends and this may negatively affect the price of our stock.

Under the terms of our 2021 Credit Agreement, our ability to pay dividends on our common stock is limited and we do not anticipate paying dividends on our common stock in the foreseeable future. The future price of our common stock may be adversely impacted because we do not pay dividends.

Restricted stock awards, performance-based restricted stock units and the exercise of stock options may depress our stock price and may result in dilution to our common stockholders.

There are a significant number of shares of restricted stock awards (“RSUs”), performance-based restricted stock units (“PSUs”) and outstanding options to purchase our stock. If the market price of our common stock rises above the exercise price of outstanding options, holders of those securities may be likely to exercise their options and sell the common stock acquired upon exercise in the open market. Sales of a substantial number of shares of our common stock in the public market by holders of options may depress the prevailing market price for our common stock and could impair our ability to raise capital through the future sale of our equity securities. Additionally, if the holders of outstanding options exercise those options, our common stockholders will incur dilution in their relative percentage ownership.

As of December 31, 2022, options to purchase 1,719,526 shares of common stock were outstanding, at a weighted average exercise price of $8.19 per share, of which 1,241,156 were exercisable at a weighted average exercise price of $6.98 per share. In addition, RSUs of 534,080 shares, with a weighted average grant date fair value of $11.85 per share, were outstanding and were issuable upon the vesting of certain time restrictions and PSUs of 125,117 shares, with a weighted average grant date fair value of $9.51 per share, were outstanding and were issuable upon meeting certain performance-based vesting criteria.

We may be subject to limitations on net operating loss carryforwards and certain built-in losses following an ownership change.

If we experience an ownership change, either via a major transaction or a series of trades where a substantial percentage of our ownership changes, which may be less than a majority of our ownership in certain cases, we may be limited in our ability to use our net operating loss carryforwards.

The Company continues to monitor shifts in past ownership (as defined under Section 382 of the Code). As of December 31, 2022, our U.S. federal net operating loss carryforwards of approximately $29.1 million will begin to expire in various years beginning in 2031 and $6.6 million of our U.S. federal net operating loss carryforward has an indefinite life. There can be no assurance that we will not experience an ownership change in the future, in which case we may be limited in our ability to use our deferred tax assets. At December 31, 2020, management determined that the valuation allowance against the U.S. federal

16

and state deferred taxes was no longer required and the valuation allowance of $11.2 million was released, which is described under the heading “Income Taxes” in Note 10 to our Consolidated Financial Statements included in this Form 10-K.

GENERAL RISK FACTORS

The Company has identified material weaknesses in our internal control over financial reporting and those weaknesses have led to a conclusion that our internal control over financial reporting and disclosure controls and procedures were not effective as of December 31, 2022. Our inability to remediate the material weaknesses, our discovery of additional weaknesses, and our ability to achieve and maintain effective disclosure controls and procedures and internal control over financial reporting could affect our ability to ensure timely and reliable financial reports, affect the ability of our auditors to attest to the effectiveness of our internal controls, and weaken investor confidence in our financial reporting.

The Company's management is responsible for establishing and maintaining adequate internal controls over its financial reporting, as defined in Rule 13a-15(f) and 15d-15(f) under the Securities Exchange Act. As disclosed in Item 9A of Part II of this report, the Company identified material weaknesses in its internal controls as of December 31, 2022. Please see the discussion of these conclusions below under Item 9A. “Controls and Procedures” of this Annual Report on Form 10-K. Due to the material weaknesses in the Company's internal control over financial reporting, the Company also concluded that its disclosure controls and procedures were not effective as of December 31, 2022.

The Company is actively engaged in developing a remediation plan designed to address each material weakness, but cannot be certain as to when its remediation plans will be fully completed. If the remedial measures are insufficient to address the material weaknesses or if additional material weaknesses or significant deficiencies in the internal controls are discovered or occur in the future, the consolidated financial statements may contain material misstatements and the Company could be required to restate its financial results, which could materially and adversely affect the Company's business and results of operations or financial condition, restrict its ability to access the capital markets, require the Company to expend significant resources to correct the weaknesses or deficiencies, subject it to fines, lawsuits, penalties, judgements or other legal expenses, harm its reputation, create delays or the inability to meet future SEC reporting obligations or otherwise cause a decline in investor confidence.

The effects of a global pandemic or disease outbreak, such as the COVID-19 pandemic could disrupt our operations and adversely affect our business, financial condition, results of operations and cash flows.

The COVID-19 pandemic caused significant volatility, uncertainty, and disruption in economic activity and financial markets globally, the effects of which are still continuing. Although the COVID-19 pandemic did not had any material unfavorable effect on our results of operations to date, there can be no assurance that a resurgence of the COVID-19 pandemic, or any other global pandemic or disease outbreak, will not have a material adverse effect on our future operational and financial performance. The ultimate extent to which the COVID-19 pandemic, or any future global pandemic or disease outbreak, could impact our operational and financial performance in future periods is currently uncertain and will depend on numerous evolving factors and future developments that we may not be able to accurately predict and to which we may not be able to respond. Such factors and developments include, but are not limited to: the duration, severity and spread of the outbreak; actions taken by government authorities to contain and mitigate the outbreak and the effectiveness of such actions (including the efficacy and distribution of any vaccines); the effect on the U.S. and global economies and actions taken in response; the overall impact on the businesses of our customers, partners, vendors and suppliers; the health of and effect on our workforce; the future effects to our operational and financial results of the changes we have made to protect the safety and well-being of our employees and future operational disruptions or challenges we may face; increased cybersecurity and information security risk as a result of the transition of our employees to a remote work environment; and how quickly and to what extent normal economic and operating conditions may resume. A prolonged outbreak of a disease, illness or virus could, among other things, strain our business continuity plans, create delays in our growth and strategic initiatives, reduce our sales and marketing activities, limit our sales peoples’ access to our clients, limit our access to financing on favorable terms, increase our exposure to potential impairment charges related to long-lived and intangible assets, hinder our ability to support our clients and operate our business effectively, heighten the risk of disruption to our information and reporting systems and internal controls, including those over financial reporting and other risk management systems, or require us to incur substantial costs. We cannot predict the degree to which the effects of the COVID-19 pandemic will ultimately impact our operations, however, the effects of the COVID-19 pandemic, or any other global pandemic or disease outbreak, alone or taken together, could adversely affect our future business, financial condition, results of operations and cash flows, and may also heighten other risks to which the Company is subject, including other risks discussed in this annual report on Form 10-K.

17

We may become subject to legal and regulatory proceedings that could have a material adverse impact on our business, results of operations and financial condition.

From time to time and in the ordinary course of our business, we and certain of our subsidiaries may become involved in various legal and regulatory proceedings. All such proceedings are inherently unpredictable and, regardless of the merits of the claims, litigation and regulatory proceedings may be expensive, time-consuming and disruptive to our operations and distracting to management. If resolved against us, such proceedings could result in excessive verdicts, injunctive relief or other equitable relief that may affect how we operate our business. Similarly, if we settle such proceedings, it may affect how we operate our business. Future court decisions, alternative dispute resolution awards, business expansion or legislative activity may increase our exposure to litigation and regulatory investigations. In some cases, substantial non-economic remedies or punitive damages may be sought. Although we maintain liability insurance coverage, there can be no assurance that such coverage will cover any particular verdict, judgment or settlement that may be entered against us, that such coverage will prove to be adequate or that such coverage will continue to remain available on acceptable terms, if at all. If we incur liability that exceeds our insurance coverage or that is not within the scope of the coverage in proceedings brought against us, it could have a material adverse effect on our business, results of operations and financial condition.

We do not collect sales or consumption taxes in some jurisdictions.

Our core services are exempt from sales tax or its equivalent in many states. However, there are several states that consider pump rentals, sales and services taxable regardless of method of payment. We are collecting sales tax or its equivalent in numerous jurisdictions. A successful assertion by one or more states or localities requiring us to collect taxes where we currently do not, could result in substantial tax liabilities, including for past sales, as well as penalties and interest.

If we are unsuccessful in our efforts to implement and support information technology improvements or respond to technological changes, our growth, prospects and results of operations could be adversely affected.

To remain competitive, we must continue to enhance and improve the functionality and features of our technology solutions and services. We have implemented a service to support EMR technology with some of our outpatient infusion practices that enables billing information to be transferred between us and medical facilities electronically and automatically, thus eliminating the current use of mail, email and/or faxes. We have also implemented a web portal that supports our rental and service customers. If these efforts cease to be successful, our reputation and ability to attract and retain customers and contributors will be adversely affected. Furthermore, we are likely to incur expenses in connection with continuously updating and improving our technology infrastructure and services. Without such improvements, our operations might suffer from unanticipated system disruptions, slow application performance or unreliable service levels, any of which could negatively affect our reputation and ability to attract and retain customers and contributors. We may face significant delays in introducing new services, products and enhancements.

If competitors introduce new products and services using new technologies or if new industry standards and practices emerge, our existing technology and systems may become obsolete or less competitive, and our business may be harmed. In addition, the expansion and improvement of our systems and infrastructure will require us to commit substantial financial, operational and technical resources, with no assurance that our business will improve.

All of these factors could have a material adverse impact on our business, financial condition, results of operations and cash flows.

Cybersecurity risks and cyber incidents could adversely affect our business and disrupt operations.

Cyber incidents can result from deliberate attacks or unintentional events. These incidents can include, but are not limited to, gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. The result of these incidents could include, but are not limited to, disrupted operations, misstated financial data, liability for stolen assets or information, increased cybersecurity protection costs, litigation and reputational damage adversely affecting customer or investor confidence. We have implemented systems and processes to focus on identification, prevention, mitigation and resolution. However, these measures cannot provide absolute security, and our systems may be vulnerable to cybersecurity breaches such as viruses, hacking, and similar disruptions from unauthorized intrusions. In addition, we rely on third party service providers to perform certain services, such as payroll and tax services. Any failure of our systems or third-party systems may compromise our sensitive information and/or personally identifiable information of our employees or patient health information subject to HIPAA confidentiality requirements. While we have secured cyber insurance to potentially cover certain risks associated with cyber incidents, there can be no assurance the insurance will be sufficient to cover any such liability.

18

Technological interruptions or the efficiency of our website and technology solutions could damage our reputation and brand and adversely affect our results of operations.

The satisfactory performance, security, reliability and availability of our network infrastructure are critical to our reputation, our ability to attract, communicate with and retain customers and our ability to maintain adequate customer service levels. Any system interruptions, outside intrusions, or security breaches could result in negative publicity, damage our reputation and brand or adversely affect our results of operations. We may experience temporary system interruptions for a variety of reasons, including security breaches and other security incidents, viruses, telecommunication and other network failures, power failures, software errors or data corruption. We rely upon third-party service providers, such as co-location and cloud service providers, for our data centers and application hosting, and we are dependent on these third parties to provide continuous power, cooling, internet connectivity and physical security for our servers. In the event that these third-party providers experience any interruption in operations or cease business for any reason, or if we are unable to agree on satisfactory terms for continued hosting relationships, our business could be harmed and we could be forced to enter into a relationship with other service providers or assume hosting responsibilities ourselves. Although we operate two data centers in an active/standby configuration for geographic and vendor redundancy and even though we maintain a third disaster recovery facility to back up our content collection, a system disruption at the active data center could result in a noticeable disruption of our services. Because some of the causes of system interruptions may be outside of our control, we may not be able to remedy such interruptions in a timely manner, or at all.

All of these factors could have a material adverse impact on our business, financial condition, results of operations and cash flows.

Natural disasters, pandemics, acts of war or terrorism and other external events could significantly impact our business.

Natural disasters, including hurricanes, earthquakes, floods, excessive snowfall and other unfavorable weather conditions, pandemics, such as the COVID-19 pandemic, acts of war or terrorism and other adverse external events may affect our operations. Such events may have a detrimental effect on our gross revenue, preventing many patients from visiting a facility to obtain our ambulatory infusion pumps or receive treatment. Similarly, such events could impact key suppliers or vendors, disrupting the services or materials they provide us. The severity of these occurrences, should they ever occur, will determine the extent to which and if our business, financial condition, results of operations and cash flows is materially and adversely affected.

We are dependent upon executive officers and other key personnel. The loss of any of our executive officers or other key personnel could reduce our ability to manage our businesses and achieve our business plan, which could cause our sales to decline and our operating results and cash flows to suffer.

Our success is substantially dependent on the continued services of our executive officers and other key personnel who generally have extensive experience in our industry. Our future success also will depend in large part upon our ability to identify, attract and retain other highly qualified executive officers, managerial, finance, technical, clinical, customer service and sales and marketing personnel. Competition for these individuals is intense, more so in the current labor market. The loss of the services of any executive officer or other key employee, or our failure to attract and retain other qualified and experienced personnel on acceptable terms, could have a material and adverse effect on our business, financial condition, results of operations and cash flows.

Item 2.    Properties.

We do not own any real property. We lease office and warehouse space at the following locations:

City	State/Country
Rochester Hills	Michigan
Lenexa	Kansas
Canton	Massachusetts
Bakersfield	California
Santa Fe Springs	California
Mesquite	Texas

We believe that such office and warehouse space is suitable and adequate for our business. All of our facilities are utilized to support both of our segments.

Item 3.    Legal Proceedings.

From time to time in the ordinary course of our business, we may be involved in legal and regulatory proceedings, the outcomes of which may not be determinable. The results of litigation and regulatory proceedings are inherently unpredictable. Any claims against us, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time and result in diversion of significant resources. We are not able to estimate an aggregate amount or range of reasonably possible losses for those legal matters for which losses are not probable and estimable, primarily for the following reasons: (i) many of the relevant legal proceedings are in preliminary stages and until such proceedings develop further, there is often uncertainty regarding the relevant facts and circumstances at issue and potential liability; and (ii) many of these proceedings involve matters of which the outcomes are inherently difficult to predict. We have insurance policies covering certain potential losses where such coverage is cost effective.

We are not at this time involved in any proceedings that we believe could have a material effect on our business, financial condition, results of operations or cash flows.

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

The following discussion should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in this Form 10-K. The forward-looking statements included in this discussion and elsewhere in this Form 10-K involve risks and uncertainties, including those set forth under “Cautionary Statement About Forward-Looking Statements.” Actual results and experience could differ materially from the anticipated results and other expectations expressed in our forward-looking statements as a result of a number of factors, including but not limited to those discussed in this Item and in Item 1A - “Risk Factors.” For discussion and analysis of the year ended December 31, 2021 compared to the year ended December 31, 2020, please refer to Management's Discussion and Analysis of Financial Condition and Results of Operations included in Part II, Item 7 of our Annual Report on Form 10-K for the year ended December 31, 2021, filed with the SEC on March 15, 2022.

Overview

We are a leading national health care service provider, facilitating outpatient care for Durable Medical Equipment manufacturers and health care providers. We provide our products and services to hospitals, oncology practices, ambulatory surgery centers, and other alternate site health care providers. Our headquarters is in Rochester Hills, Michigan, and we operate our business from a total of seven locations in the U.S. and Canada. We deliver local, field-based customer support as well as operate pump service and repair Centers of Excellence in Michigan, Kansas, California, Massachusetts, Texas and Ontario, Canada. ISI is accredited by the Community Health Accreditation Partner (CHAP) while First Biomedical is ISO 9001 certified at our Kansas, Michigan, Massachusetts, Canada and Santa Fe Springs, California locations and also ISO 13485 certified at our Bakersfield, California location.

InfuSystem competes for and retains its business primarily on the basis of its long participation and strong reputation in the Durable Medical Equipment space, its long-standing relationships with Durable Medical Equipment manufacturers and its health care provider customers, and the high levels of service it provides. Current barriers to entry for potential competitors are created by our: (i) growing number of third-party payer networks under contract, which included nearly 800 third-party payer networks as of December 31, 2022, an increase of 4% over the prior year period; (ii) economies of scale, which allow for predictable reimbursement and less costly purchase and management of the pumps, respectively; (iii) established, long-standing relationships as a provider of pumps to outpatient oncology practices in the U.S. and Canada; (iv) pump fleet of ambulatory and large volume infusion pumps for rent and for sale, which may allow us to be more responsive to the needs of physicians, outpatient oncology practices, hospitals, outpatient surgery centers, homecare practices, patient rehabilitation centers and patients than a new market entrant; (v) seven geographic locations in the U.S. and Canada that allow for same day or next day delivery of pumps; (vi) growing team of field-based and traveling biomedical technicians; and (vii) a wide array of pump repair and service capabilities. We do not perform any research and development on pumps, but we have made, and continue to make investments in our information technology.

ITS Segment

Our ITS segment’s core purpose is to seek opportunities to leverage our unique know-how in clinic-to-home health care involving Durable Medical Equipment, our logistics and billing capabilities, our growing network of third-party payers under contract, and our clinical and biomedical capabilities. This leverage may take the form of new products and/or services, strategic alliances, joint ventures and/or acquisitions. The leading service within our ITS segment is our Oncology Business. Colorectal cancer is the fourth most prevalent form of cancer in the U.S., according to the American Cancer Society, and the standard of care for the treatment of colorectal cancer relies upon continuous chemotherapy infusions delivered via ambulatory infusion pumps. One of the goals for the ITS segment is to expand into treatment of other types of cancers. In 2022, our Oncology Business approximated 91% of our total ITS segment revenues. In 2022, we generated approximately 47% of our total ITS segment revenues from treatments for colorectal cancer and 44% of our ITS segment revenues from treatments for non-colorectal disease states. There are a number of approved treatment protocols for pancreatic, head and neck, esophageal and other types of cancers, as well as other disease states which present opportunities for growth. There are also a number of other drugs currently approved by the FDA, as well as agents in the pharmaceutical development pipeline, which we believe could potentially be used with continuous infusion protocols for the treatment of diseases other than colorectal cancer. Additional drugs or protocols currently in clinical trials may also obtain regulatory approval over the next several years. If these new drugs or protocols obtain regulatory approval for use with continuous infusion protocols, we expect the pharmaceutical companies to focus their sales and marketing efforts on promoting the new drugs and protocols to physicians.

Furthermore, our Oncology Business focuses mainly on the continuous infusion of chemotherapy. Continuous infusion of chemotherapy can be described as the gradual administration of a drug via a small, lightweight, portable infusion pump over a prolonged period of time. A cancer patient can receive his or her medicine anywhere from one to 30 days per month depending on the chemotherapy regimen that is most appropriate to that individual’s health status and disease state. This may

23

be followed by periods of rest and then repeated cycles with treatment goals of progression-free disease survival. This drug administration method has replaced intravenous push or bolus administration in specific circumstances. The advantages of slow continuous low doses of certain drugs are well documented. Clinical studies support the use of continuous infusion chemotherapy for decreased toxicity without loss of anti-tumor efficacy. The NCCN Guidelines recommend the use of continuous infusion for treatment of numerous cancer diagnoses. We believe that the growth of continuous infusion therapy is driven by three factors: evidence of improved clinical outcomes; lower toxicity and side effects; and a favorable reimbursement environment.

The use of continuous infusion has been demonstrated to decrease or alter the toxicity of a number of cytotoxic, or cell killing agents. Higher doses of drugs can be infused over longer periods of time, leading to improved tolerance and decreased toxicity. For example, the cardiotoxicity (heart muscle damage) of the chemotherapy drug Doxorubicin is decreased by schedules of administration according to The Chemotherapy Source Book by Michael C. Perry. Nausea, vomiting, diarrhea and decreased white blood cell and platelet counts are all affected by duration of delivery. Continuous infusion can lead to improved tolerance and patient comfort while enhancing the patient’s ability to remain on the chemotherapy regimen. Additionally, the lower toxicity profile and resulting reduction in side effects enables patients undergoing continuous infusion therapy to continue a relatively normal lifestyle, which may include continuing to work, going shopping, and caring for family members. We believe that the partnering of physician management and patient autonomy provide for the highest quality of care with the greatest patient satisfaction.

We believe that oncology practitioners have a heightened sensitivity to providing quality service and to their ability to obtain reimbursement for services they provide. Simultaneously, CMS and private insurers are increasingly focused on evidence-based medicine to inform their reimbursement decisions — that is, aligning reimbursement with clinical outcomes and adherence to standards of care. Continuous infusion therapy is a main component of the standard of care for certain types of cancers because clinical evidence demonstrates superior outcomes. Payers’ recognition of this benefit is reflected in their relative reimbursement policies for clinical services related to the delivery of this care.

Additional areas of focus for our ITS segment are as follows:

•Pain Management - providing our ambulatory pumps, products, and services for pain management in the area of post-surgical continuous peripheral nerve block.

•Wound Care - launched in November 2022, the Company established the SI Wound Care partnership with Sanara. The partnership will focus on delivering a complete wound care solution targeted at improving patient outcomes, lowering the cost of care, and increasing patient and provider satisfaction. The partnership is expected to enable InfuSystem to offer innovative products including Cork NPWT devices and supplies and Sanara's advanced wound care product line to new customers through the jointly controlled entity.

•Acquisitions - we believe there are opportunities to acquire smaller, regional health care service providers, in whole or in part that perform similar services to us but do not have the national market access, network of third-party payer contracts or operating economies of scale that we currently enjoy. We may also pursue acquisition opportunities of companies that perform similar services, but offer different therapies or utilize different devices.

•Lymphedema Therapy – Lymphedema therapy includes providing patient care and customer service, pneumatic compression devices and associated garments through our partnership with Bio Compression Systems, Inc. to outpatients, initially targeting our existing acute care and oncology customers, estimated to be 20% of the multi-billion-dollar Lymphedema market.

•Information technology-based services - we also plan to continue to capitalize on key new information technology-based services such as EXPRESS, InfuBus or InfuConnect, Pump Portal, DeviceHub and BlockPain Dashboard®.

The payer environment within our ITS segment is in a constant state of change. We continue to extend our considerable breadth of payer networks under contract as patients move into different insurance coverage plans, including Medicaid and Insurance Marketplace products. In some cases, this may slightly reduce our aggregate billed revenues payment rate but result in an overall increase in collected revenues, due to a reduction in concessions. Consequently, we are increasingly focused on net revenues less concessions.

DME Services Segment

Our DME Services segment’s core service is to: (i) sell or rent new and pre-owned pole-mounted and ambulatory infusion pumps and other Durable Medical Equipment; (ii) sell treatment-related consumables; and (iii) provide biomedical recertification, maintenance and repair services for oncology practices as well as other healthcare site settings, including, home care and home infusion providers, skilled nursing and acute care facilities, pain centers and others. We purchase new and pre-

24

owned pole-mounted and ambulatory infusion pumps from a variety of sources on a non-exclusive basis. We repair, refurbish and provide biomedical certification for the devices as needed. The pumps are then available for sale, rental or to be used within our ambulatory infusion pump management service. Our acquisition of FilAMed, a privately-held biomedical services company, on January 31, 2021 has supplemented the Company’s existing biomedical recertification, maintenance and repair services for acute care facilities and other alternate site settings, including, home care and home infusion providers, skilled nursing facilities, pain centers and others. Our acquisition of OB Healthcare, a privately-held biomedical services company, on April 18, 2021 further develops and expands InfuSystem’s DME Services segment by adding field service capabilities and complements the Company’s purchase of FilAMed.

Key Business Metrics

Our management monitors a number of financial and non-financial measures and ratios on a regular basis in order to track the progress of our business and make adjustments as necessary. We believe that the most important of these measures and ratios include net revenues and our order-to-cash process, fleet utilization, operating margin, operating expenses, profitability, and debt levels including available credit and leverage ratios. These measures and ratios are compared to standards or objectives set by management, so that actions can be taken, as necessary, in order to achieve the standards and objectives.

COVID-19 Update

On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, which spread globally and throughout the U.S.. In response, we took a number of precautionary and preemptive steps to protect the safety and well-being of our employees while ensuring continuity of service to our clients and undertook preparedness plans at our facilities to maintain continuity of operations, which provide for flexible work arrangements without any significant disruptions to our business or control processes. Our management team is continuing to actively monitor the situation and is in constant communication with our workforce as well as with our customers and vendors.

The COVID-19 global pandemic caused significant disruption to the U.S. and global economies and has severely impacted the overall healthcare industry and the related supply chain. During 2020, the focus on preparing and treating large numbers of COVID-19 patients resulted in significant shifts in demand and related shortages in certain types of medical equipment, including infusion pumps, while at the same time reducing capacity for non-COVID-19 services such as elective surgeries. During 2020, these impacts created a significant net favorable dynamic for InfuSystem resulting in increased net revenues and margins in certain of our service lines only partially offset by reductions in others. Some of these benefits did not occur in 2022 or 2021, such as elevated levels of sales of new and pre-owned medical equipment, whereas some diminished during these periods, including a portion of the increased volume of rental revenues. During 2021, outbreaks of COVID-19, including the Delta and Omicron variants, unfavorably impacted our revenue growth initiatives in certain product lines including Pain Management and NPWT, The impacts included scattered restrictions on elective surgeries and delayed ramp-up in treatment volumes for new customers, both of which unfavorably impacted the Pain Management business, and restricted physical access to our customers facilities, which unfavorably impacted both the Pain Management and NPWT businesses. During 2022, disruptions in our supply of disposable medical supplies impacted our ability to add new customers, mainly in the the Pain Management business. The COVID-19 pandemic continues to heighten potential risks that did not impact the Company in 2020, 2021 or 2022, but may impact the Company on a delayed basis, such as disruptions in our supply chain and increased costs of the products we sell and for our labor force. We continue to prepare for disruptions in the current and future periods, both positive and negative.

While the COVID-19 pandemic has not had any material unfavorable effect on our operations to date, the extent and nature of the impact in the future, if any, will depend on future developments, which are highly uncertain, cannot be predicted and could have a material adverse impact on our financial position, operating results and cash flows.

Net Revenues

Net revenues for the year ended December 31, 2022 were $109.9 million, an increase of $7.5 million, or 7.4%, compared to $102.4 million for the year ended December 31, 2021. The increase included higher net revenues for both the ITS and DME Services segments.

ITS

ITS net revenue of $68.9 million increased $3.3 million, or 5.0%, during the year ended December 31, 2022 as compared to the prior year. This increase was primarily attributable to additional treatment volume in Oncology and Pain Management, and improved third party payer collections on billings. Pain Management net rental revenue for 2022 increased by $1.0 million, or 28.4%, as compared to the same period in 2021. This increase, due to expansion of the program to additional customer sites of care over the last two years, occurred despite treatment volumes being unfavorably impacted by decreased elective surgeries during the first few months of 2022 related to COVID-19.

26

DME Services

DME Services net revenue of $41.0 million (exclusive of inter-segment revenues) increased $4.2 million, or 11.6%, during 2022 as compared to the prior year. DME Services net revenue excludes inter-segment revenues for both periods. This increase included higher biomedical services revenue which increased by $2.3 million, or 50%, and increased equipment rentals totaling $1.8 million, or 11%. The increased biomedical revenue included revenue totaling $1.2 million from a new master services agreement with a leading global healthcare technology and diagnostic company that was launched in April 2022. During 2022, revenue under the contract represented the initial stages of an overall ramp-up period which was originally expected to span the first 15 months of the contract period and reach revenue totaling $10 to $12 million annually. The actual onboarding pace realized during 2022 has been slower than originally expected, however, during 2023 the monthly on-boarding rate is expected to accelerate. We now anticipate reaching an annualized run rate of $10 million by September 2023, 18 months after the initial launch, and $12 million by December 2023. On-boarding activities are expected to level off during the first quarter of 2024 to bring total annualized revenue under the contract to an amount slightly above the original expected range. Higher revenue also included approximately $0.5 million related to the full-period effect from the acquisitions of the FilAMed and OB Healthcare businesses during the first and second quarters of 2021, respectively and increased rental revenue reflecting increased market demand as customers looked to supplement their infusion pump fleets in the face of supply chain disruptions of disposable medical supplies used with certain model infusion pumps.

Gross Profit (inclusive of certain inter-segment allocations)

Gross profit for the year ended December 31, 2022 totaling $62.6 million increased $2.4 million, or 3.9%, from $60.2 million during the year ended December 31, 2021. The increase was driven by the increase in net revenues partially offset by a lower gross profit as a percentage of net revenue (“gross margin”). Gross margin decreased to 56.9% during 2022, as compared to 58.8% during the prior year period, a decrease of 1.9%. The increase in gross profit was attributable to both the ITS and DME Services segments. Similarly, the gross margin was lower for both operating segments during 2022 as compared to 2021.

ITS

ITS gross profit was $43.4 million, during 2022, representing an increase of $1.4 million, or 3.3%, compared to the prior year. The improvement reflected an increase in net revenues offset partially by a lower gross margin which was 63.1% during 2022, a decrease of 1.0%, from the prior year. The lower gross margin was the result of a $1.0 million increase in the adjustment recorded for pump disposal expenses and $0.7 million higher pump maintenance expenses as compared to the prior year. These increased expenses were partially offset by improved third party payer collections on billings and improved coverage of fixed costs from the higher net revenue. Pump disposal expenses include retirements of damaged pumps and reserves for missing pumps. The increase was mainly related to an updated estimate of the volume of pumps considered missing based on pump return data and physical inventories. Pump maintenance expenses, which include preventative maintenance, cleaning and repair services mainly performed by the DME Services segment, were unusually high during the second and third quarters of 2022 due to the timing of service performance.

DME Services

DME Services gross profit during 2022 was $19.1 million, representing an increase of $1.0 million, or 5.4%, over the prior year. This increase was due to higher net revenue partially offset by lower gross margin. The DME gross margin was 46.6% during 2022, which was 2.7% lower than the prior year. This decrease was the result of gross margin mix associated with higher biomedical services revenue, which has a lower gross margin percentage than other business lines in the DME Services segment, and an increase in labor costs related to an increase in the number of biomedical technicians hired in order to increase the capacity in biomedical services in anticipation of increased biomedical services demand. Higher biomedical services revenue anticipated in 2023 is expected to absorb the increased labor costs.

Amortization of Intangible Assets

Amortization of intangible assets for the year ended December 31, 2022 was $2.5 million compared to $4.3 million for the year ended December 31, 2021 representing a decrease of $1.8 million, or 41.5%. The decrease is attributable to certain intangible assets becoming fully amortized. Amortization expense is expected to decrease further in 2023 to less than $1.0 million based on the current amortization schedule.

Selling and Marketing Expenses

Selling and marketing expenses for the year ended December 31, 2022 were $12.3 million, an increase of $1.5 million, compared to 2021. Selling and marketing expenses as a percentage of net revenues increased to 11.2% compared to 10.5% in

27

2021. This increase reflected $1.2 million in increased marketing expenses and higher customer travel expenses totaling $0.1 million. The higher marketing expenses related to expansion of our digital marketing activities, higher costs for our national sales meeting, which was held in-person for the first time since the outbreak of COVID-19, increased participation in trade shows and other increased expenses. The higher travel expenses occurred because travel restrictions related to COVID-19 were lifted during 2021 and, accordingly, travel activities increased during 2022. Selling and marketing expenses during these periods consisted of sales personnel salaries, commissions and associated fringe benefit and payroll-related items, marketing, overall travel and entertainment and other miscellaneous expenses.

General and Administrative (“G&A”) Expenses

G&A expenses for the year ended December 31, 2022 were $46.1 million, an increase of 9.0% from $42.3 million for the year ended December 31, 2021. G&A expenses during these periods consisted primarily of accounting, administrative, third-party payer billing and contract services, customer service, nurses on staff, new product services, service center personnel salaries, fringe benefits and other payroll-related items, professional fees, legal fees, stock-based compensation, annual management incentive bonuses, insurance and other miscellaneous items. The increase of $3.8 million, included $1.5 million in inflation related increases in wages and employee benefits, a $1.7 million increase in the expense for our short-term incentive compensation plan, approximately $1.0 million in IT related expenses to develop business applications for the Biomedical Services business, $0.7 million in additional audit expenses associated with additional requirements to comply with the Sarbanes-Oxley Act of 2002, $0.6 million in severance and other termination costs associated with a reorganization of certain management positions and $0.1 million of additional G&A expenses for the FilAMed and OB Healthcare businesses. Other increased expenses totaling $2.1 million were associated with revenue volume growth and included the cost of additional personnel, information technology and general business expenses. These increases were partially offset by a decrease in stock-based compensation expense of $2.6 million. G&A expenses as a percentage of net revenues for 2022 increased to 41.9% compared to 41.3% for the prior year mainly reflecting the year-over-year increases offset partially by improved net revenue leverage of fixed costs.

Other Income and Expenses

During the year ended December 31, 2022, we incurred interest expense of $1.4 million, which approximately equaled interest expense during the year ended December 31, 2021.

Provision for/Benefit from Income Taxes

During the year ended December 31, 2022, the Company recorded a provision for income taxes of $0.1 million, representing an effective tax rate of negative 86.0% on pre-tax income totaling $0.1 million. This effective tax rate for 2022 differed from the U.S. statutory rate mainly due to state, local and foreign taxes and permanent differences between expense recognized for book purposes versus tax purposes including differences associated in the amounts of equity compensation expense and limits on compensation for certain executive members of management. During the year ended December 31, 2021, the Company recorded a benefit from income taxes of $0.2 million, representing an effective tax rate of negative 13% on pre-tax income totaling $1.3 million. This effective tax rate for 2021 differed from the U.S. statutory rate mainly due to permanent differences in the amounts of equity compensation expense recognized for book purposes versus tax purposes.

Subsequent Events

We have evaluated subsequent events through the date that our consolidated financial statements are issued with nothing to report.

Liquidity and Capital Resources

Overview:

We finance our operations and capital expenditures with cash generated from operations and borrowings under our existing credit agreements. On February 5, 2021, we and certain of our subsidiaries, as borrowers, entered into a Credit Agreement (the “2021 Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent, sole bookrunner and sole lead arranger, and the lenders party thereto, which replaced our then existing credit facility, dated March 23, 2015 (the “2015 Credit Agreement”). See Note 8 (Debt) in the notes to the accompanying condensed consolidated financial statements for additional information regarding the 2021 Credit Agreement and 2015 Credit Agreement.

The following table summarizes our available liquidity (in millions):

	December 31, 2022		December 31, 2021
Cash and cash equivalents	$	0.2	0.2
Revolving line of credit availability	41.2		41.4
Available liquidity	$	41.4	41.6

Our liquidity and borrowing plans are established to align with our financial and strategic planning processes and ensure we have the necessary funding to meet our operating commitments, which primarily include the purchase of pumps, inventory, payroll and general expenses. We also take into consideration our overall capital allocation strategy which includes investment for future organic growth, potential acquisitions and share repurchases. We believe we have adequate sources of liquidity and funding available for at least the next year from the filing date of this report, as well as for our currently anticipated long-term needs. However, any projections of future earnings and cash flows are subject to substantial uncertainty, including factors such as the successful execution of our business plan and general economic conditions. We may need to access debt and equity markets in the future if unforeseen costs or opportunities arise, to meet working capital requirements, fund acquisitions or investments or repay indebtedness under the 2021 Credit Agreement. If we need to obtain new debt or equity financing in the future, the terms and availability of such financing may be impacted by economic and financial market conditions as well as our financial condition and results of operations at the time we seek additional financing.

Long-Term Debt Activities:

The 2021 Credit Agreement provides for a revolving credit facility (the “Revolving Facility”) of $75.0 million, maturing on February 5, 2026. The Revolving Facility may be increased by $25.0 million, subject to certain conditions, including the consent of the Agent and obtaining necessary commitments. The lenders under the 2021 Credit Agreement may issue up to $7.0 million in letters of credit subject to the satisfaction of certain conditions. On February 5, 2021, the Borrowers made an initial borrowing of $30.0 million under the Revolving Facility. Proceeds from the loan, along with approximately $8.2 million in cash, were used to repay all amounts due under the Company’s then existing 2015 Credit Agreement.

The 2021 Credit Agreement has customary representations and warranties. The ability to borrow under the facility is subject to ongoing compliance with a number of customary affirmative and negative covenants, including limitations on indebtedness, liens, mergers, acquisitions, investments, asset sales, affiliate transactions and restricted payments, as well as financial covenants, including the following:

•a minimum fixed charge coverage ratio (defined as the ratio of consolidated EBITDA (as defined in the 2021 Credit Agreement) less 50% of depreciation expense), to consolidated fixed charges (as defined in the 2021 Credit Agreement)) for the prior four most recently ended calendar quarters of 1.20 to 1.00; and

•a maximum leverage ratio (defined as total indebtedness to EBITDA for the prior four most recently ended calendar quarters) of 3.50 to 1.00.

The 2021 Credit Agreement includes customary events of default. The occurrence of an event of default will permit the lenders to terminate commitments to lend under the Revolving Facility and accelerate payment of all amounts outstanding thereunder.

On February 5, 2021, in connection with the execution and closing of the 2021 Credit Agreement, the Company, along with its wholly owned subsidiaries as borrowers, terminated the 2015 Credit Agreement. All outstanding loans under the 2015 Credit Agreement have been repaid and all liens under the 2015 Credit Agreement have been released, except that a letter of credit originally issued under the 2015 Credit Agreement in the amount of approximately $0.8 million was transferred to the 2021 Credit Agreement.

The 2021 Credit Agreement was accounted for as a debt modification that resulted in a small increase to deferred debt issuance costs. As of December 31, 2022, the Company was in compliance with all debt-related covenants under the 2021 Credit Agreement.

On April 15, 2019, the Company sold for $2.0 million and immediately leased back certain medical equipment in rental service to a third party specializing in such transactions. The leaseback term was 36 months. Because the arrangement contained a purchase option that the Company was reasonably certain to exercise, this transaction did not qualify for the sale-

29

leaseback accounting under ASC 842. The medical equipment remains recorded on the accompanying condensed consolidated balance sheet and the proceeds received had been classified as other financing liability. During the fourth quarter of 2021, the Company recorded and additional $0.2 million of interest expense to reflect the amount expected to be paid upon the exercise of the purchase option at the end of its other financing transaction. As of December 31, 2022, all amounts owed under this arrangement had been paid.

The following table illustrates the net availability under the Revolving Facility as of the applicable balance sheet date (in thousands):

	December 31, 2022		December 31, 2021
Revolver:
Gross availability	$	75,000	$	75,000
Outstanding draws	(33,384)		(32,974)
Letters of credit	(400)		(600)
Availability on Revolver	$	41,216	$	41,426

As of December 31, 2022, amounts outstanding under the Revolving Facility provided under the 2021 Credit Agreement bear interest at a variable rate equal to, at the Company’s election, a LIBO Rate for Eurodollar loans or an Alternative Base Rate for ABR loans, as defined by the 2021 Credit Agreement, plus a spread that will vary depending upon the Company’s leverage ratio. The spread ranges from 2.00% to 3.00% for Eurodollar Loans and 1.00% to 2.00% for base rate loans. The weighted-average Eurodollar loan rate at December 31, 2022 was 6.52% (LIBO of 4.27% plus 2.25%). The actual ABR loan rate at December 31, 2022 was 8.75% (lender’s prime rate of 7.50% plus 1.25%).

Share Repurchases

As noted above, our Board of Directors approved the Share Repurchase Program on June 30, 2021. As of December 31, 2022, the Company had repurchased and retired approximately $6.0 million, or 531,347 shares, of the Company's outstanding common stock under the Share Repurchase Program and had approximately $14.0 million of available repurchases remaining under the program. Repurchases under the Share Repurchase Program will be subject to market conditions, the periodic capital needs of the Company's operating activities, and the continued satisfaction of all covenants under the Company's existing credit agreement. The Share Repurchase program does not obligate the Company to repurchase shares and may be suspended, terminated, or modified at any time.

Cash Flows:

The following table summarizes our cash flows (in millions):

	Years Ended December 31,
In millions	2022		2021		2022 vs. 2021
Net cash provided by operating activities	$	17.5	$	18.3	$	(0.8)
Net cash used in investing activities	$	(11.5)	$	(21.3)	$	9.8
Net cash used in financing activities	$	(6.1)	$	(6.5)	$	0.4

Operating Cash Flow.  Net cash provided by operating activities for the year ended December 31, 2022 was $17.5 million compared to $18.3 million for the year ended December 31, 2021. This $0.8 million, or 4.4%, decrease was primarily attributable to a decrease in net income adjusted for non-cash items of $17.1 million during 2022 as compared to $21.0 million during 2021, a decrease of $3.9 million, or 18.5%. This amount was partially offset by favorable cash flow effect from changes in working capital amounts which represented a net source of cash during 2022 totaling $0.4 million versus a net use of cash during 2021 of $2.7 million, or a net favorable improvement totaling $3.1 million.

The decrease in net income adjusted for non-cash items resulted from the increases in our selling, marketing, and G&A expenses during 2022 as compared to 2021. These increases were partially offset by a higher gross profit. Non-cash items include depreciation, amortization, changes in the provision for doubtful accounts, loss on disposal of medical equipment, gain on sale of medical equipment, stock-based compensation and deferred income taxes.

The favorable net cash flow from changes in in working capital items included a favorable improvement in accounts payable and other liabilities offset partially by an unfavorable impact from accounts receivable. Accounts payable and other liabilities increased by $2.9 million during 2022 and decreased by $2.4 million during 2021 resulting in a net increase in cash flows totaling $5.3 million during 2022 as compared to the prior year. This change was mainly due to a reduction in the accrual

30

for our short term incentive plan which was lower, along with the associated expense, during 2021 as compared to both 2020 and 2022. During 2022, accounts receivable increased by $1.2 million and decreased by $0.8 million during 2021 resulting in a net decrease in cash flows. The change was due to an increase in growth in net revenues during the end of 2022 as compared to the end of 2021. During the fourth quarter of 2022 net revenue grew sequentially from the third quarter of 2022 by $1.6 million whereas during the fourth quarter of 2021 net revenue was the same as net revenue during the third quarter of 2021.

Investing Cash Flow. Net cash used in investing activities was $11.5 million for the year ended December 31, 2022 compared to $21.3 million for the year ended December 31, 2021. This $9.8 million decrease in net cash used was primarily due to the acquisitions of FilAMed and OB Healthcare totaling $8.0 million during 2021 and a $1.6 million decrease in purchases of medical equipment. There were no acquisitions during 2022. The lower purchase volume of medical equipment was due to a lower amount of net revenue growth in the ITS Segment, which has a greater need for medical devices in its operations, during 2022 as compared to 2021.

Financing Cash Flow.  Net cash used in financing activities for the year ended December 31, 2022 was $6.1 million compared to $6.5 million for the year ended December 31, 2021. The use of cash during 2022 included $5.5 million used to repurchase the Company's common stock, $1.2 million used to repurchase common stock to satisfy statutory withholding on employee stock-based compensation and $0.8 million used to pay a contingent consideration associated with the 2021 acquisition of OB Healthcare. Borrowings on the 2021 Revolving Line of Credit were fully offset by principal payments. The use of cash during 2021 was mainly related to the refinancing of our bank debt on February 5, 2021. Prior to that date, we operated under the 2015 Credit Agreement which included three term notes and a revolving line of credit. At the beginning of 2021, we had $9.6 million in cash on hand and no outstanding borrowings under the then outstanding revolving line of credit. The 2015 Credit Agreement was completely repaid and replaced by the 2021 Credit Agreement, which has a new $75 million revolving line of credit and no term notes. This structure allowed the Company to use a portion of its available cash, totaling $7.9 million, to reduce its overall outstanding debt on the closing date of the financing. Other amounts of cash used in financing activities during 2021 included net revolving line of credit repayments under the 2021 Credit Agreement made from our operating cash flows after the date of the February 5, 2021 refinancing totaling $3.8 million, $0.6 million used to repurchase the Company's common stock and $0.6 million in principal payments on our other financing. These amounts were partially offset by revolving line of credit borrowings totaling $8.0 million used to acquire FilAMed and OB Healthcare.

Critical Accounting Policies and Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements, including the notes thereto. We consider critical accounting policies to be those that require more significant judgments and estimates in the preparation of our consolidated financial statements, including the following: revenue recognition; leases; accounts receivable and allowance for doubtful accounts; income taxes; equity compensation valuations; and long-lived asset valuations. Management relies on historical experience and other assumptions believed to be reasonable in making its judgments and estimates. Actual results could differ materially from those estimates.

Management believes its application of accounting policies, and the estimates inherently required therein, are reasonable. These accounting policies and estimates are periodically reevaluated, and adjustments are made when facts and circumstances dictate a change.

Our accounting policies are more fully described under the heading “Summary of Significant Accounting Policies” in Note 2 to our Consolidated Financial Statements included in this Form 10-K. We believe the following critical accounting estimates are the most significant to the presentation of our financial statements and require the most difficult, subjective and complex judgments:

Revenue Recognition

Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 606 - Revenue from Contracts with Customers ("ASC 606") stipulates revenue recognition at the time and in an amount that reflects the consideration expected to be received for the performance obligations that have been provided. ASC 606 defines contracts as written, oral and through customary business practice. Under this definition, the Company considers contracts to be created at the time that the rental service is authorized or an order to purchase product is agreed upon regardless of whether or not there is a written contract.

31

The Company has three separate and distinct performance obligations offered to its customers: a rental service performance obligation, a product sale performance obligation and a service performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account for revenue recognition under ASC 606. These performance obligations are related to separate revenue streams and at no point are they combined into a single transaction. Sources of net revenues include commercial insurance payers, government insurance payers, medical facilities and patients.

The Company generates the majority of its revenue from the rental of infusion pumps to its customers and a minority of its revenue from product sales and services. For the rental service performance obligation, revenue is based on its standalone price, determined by using reimbursement rates established by third-party payer or other contracts. Revenue is recognized in the period in which the related performance obligation is satisfied, which is typically at the point in time that a patient concludes a treatment, or in certain arrangements, based on the number of pumps that a facility has onsite. The Company’s revenues related to product sales is recognized at the time that control of the product has been transferred to the customer; either at the time the product is shipped or the time the product has been received by the customer, depending on the delivery terms. The Company does not commit to long-term contracts to sell customers a certain minimum quantity of products. The Company's revenues related to services are recognized at the time that the service work has been completed.

The Company employs certain significant judgments to estimate the dollar amount of revenue, and related concessions, allocated to the rental service. These judgments include, among others, the estimation of variable consideration. Variable consideration, specifically related to the Company’s third-party payer rental revenues, is estimated as implied price concessions resulting from differences between the rates charged for services performed and the expected reimbursements for commercial payers and other implied customer concessions. The estimates for variable consideration are based on historical collections with similar payers, aged accounts receivable by payer class and payer correspondence using the portfolio approach, which provide a reasonable basis for estimating the variable portion of a transaction. The Company doesn’t believe it is probable that a significant reversal of revenue will occur in future periods because (i) there is no significant uncertainty about the amount of considerations that are expected to be collected based on collection history and (ii) the large number of sufficiently similar contracts allows the Company to adequately estimate the component of variable consideration.

Net revenues are adjusted when changes in estimates of variable consideration occur. Changes in estimates typically arise as a result of new information obtained, such as actual payment receipt or denial, or pricing adjustments by payers. Subsequent changes to estimates of transaction prices are recorded as adjustments to net revenue in the period of the change. Subsequent changes that are determined to be the result of an adverse change in the payer’s ability to pay are recorded as an adjustment to the allowance for doubtful accounts.

Leases

The Company accounts for leases following Accounting Standards Codification (“ASC”) Topic 842, Leases, ("Topic 842"). Under Topic 842, lessees are required to recognize a lease liability and right-of-use asset (“ROU asset”) for all leases and to disclose key information about leasing arrangements. Additionally, leases are classified as either financing or operating; the classification determines the pattern of expense recognition and classification within the statement of operations. The Company elected to apply its lease accounting policy only to leases with a term greater than twelve months.

Topic 842 provides practical expedients for an entity’s ongoing accounting. The Company elected the “combining lease and non-lease components” practical expedient and also elected to apply the short-term lease recognition exemption to certain leases; therefore, the Company did not recognize ROU assets and lease liabilities for these leases.

In adopting Topic 842, the Company determined and will continue to determine whether an arrangement is a lease at inception. The Company’s operating leases are primarily for office space, service facility centers and equipment under operating lease arrangements that expire at various dates over the next nine years. The Company’s leases do not contain any restrictive covenants. The Company’s office leases generally contain renewal options for periods ranging from one to five years. Because the Company is not reasonably certain to exercise these renewal options, the options are not considered in determining the lease term, and payments associated with the option years are excluded from lease payments. The Company’s office leases do not contain any material residual value guarantees. The Company’s equipment leases generally do not contain renewal options. The Company is not reasonably certain to exercise the renewal options for those equipment leases that do contain renewal options, thus, the options are not considered in determining the lease term and payments associated with the option years are excluded from lease payments.

For the Company’s equipment leases, the Company used and will use the implicit rate in the lease as the discount rate, when available. Otherwise, the Company uses its incremental borrowing rate as the discount rate. For the Company’s office leases, the implicit rate is typically not available, so the Company used and will use its incremental borrowing rate as the

32

discount rate. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments. The Company’s lease agreements include both lease and non-lease components. The Company elected the practical expedient that allows it to combine lease and non-lease components for all of its leases.

Payments due under the Company’s operating leases include fixed payments as well as variable payments. For the Company’s office leases, variable payments include amounts for the Company’s proportionate share of operating expenses, utilities, property taxes, insurance, common area maintenance and other facility-related expenses. For the Company’s equipment leases, variable payments may consist of sales taxes, property taxes and other fees.

Impairment of Long-lived Assets, including Goodwill and Intangible Assets

Goodwill is tested for impairment annually or more frequently when certain events or circumstances trigger a review. Management has the option to first assess qualitative factors such as current performance and overall economic conditions to determine whether or not it is necessary to perform a quantitative goodwill impairment test. If we choose that option, then we would not be required to perform a quantitative goodwill impairment test unless we determine that, based on a qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying value. If we determine that it is more likely than not, or if we choose not to perform a qualitative assessment, we will then proceed with the quantitative assessment. Under the quantitative test, if the fair value of a reporting unit exceeds its carrying amount, then goodwill of the reporting unit is considered to not be impaired. If the carrying amount of the reporting unit exceeds its fair value, then an impairment loss is recognized in an amount equal to the excess, up to the value of the goodwill. We performed our annual impairment analysis by using a quantitative assessment as of October 31, 2022 and determined that there was no impairment. Any changes in management's judgments could result in impairment charges in the future.

Management tests indefinite life trade names for impairment annually or more frequently if deemed necessary. Management has the option of first performing the impairment test for intangible assets with indefinite lives on a qualitative basis, by evaluating factors to determine whether it is more likely than not that an impairment exists. If it is more likely than not that an impairment exists, or if we choose not to perform a qualitative assessment, we will then proceed with a quantitative assessment. Impairment exists when the carrying amount of the intangible asset exceeds its fair value. If the carrying value of the intangible assets exceeds the fair value, an impairment loss is recognized in an amount equal to that excess. We performed our annual impairment analysis by using a quantitative assessment as of October 31, 2022 and determined that the fair value of the trade names with indefinite lives was greater than their carrying value, resulting in no impairment.

The Company assesses impairment indicators related to its internally-developed, internal-use software, specifically looking at the effectiveness and useful lives of each project and sub-project to determine if impairment indicators are present. In December 2022 and 2021, respectively, the Company assessed the impairment indicators and found none to be present.

For more information, refer to the “Goodwill and Intangible Assets” discussion included in Note 7 in the Notes to the Consolidated Financial Statements included in this Form 10-K.

We also evaluate the carrying value of other long-lived assets for impairment by analyzing the operating performance and anticipated future cash flows for those assets, whenever events or changes in circumstances indicate that the carrying amounts of such assets may not be recoverable. We evaluate the need to adjust the carrying value of the underlying assets if the sum of the expected cash flows is less than the carrying value. Our projection of future cash flows, the level of actual cash flows, the methods of estimation used for determining fair values and salvage values can impact impairment. Any changes in management’s judgments could result in greater or lesser annual depreciation and amortization expense or impairment charges in the future. Depreciation and amortization of long-lived assets is calculated using the straight-line method over the estimated useful lives of the assets.

Other long-lived assets include medical equipment in rental service which consists of equipment that the Company purchases from third-parties and is (1) for sale or rent, and (2) used in service to generate rental revenue. The Company periodically performs an analysis to identify potentially missing medical equipment and records a reserve equal to the underlying net book value.

Income Taxes

We account for income taxes under the liability method, whereby deferred tax asset or liability account balances are determined based on the difference between the financial statement and the tax basis of assets and liabilities using current tax laws and rates in effect for the year in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets when we expect the amount of tax benefit to be realized is less than the carrying value of the deferred tax asset.

Item 7A.    Quantitative and Qualitative Disclosure About Market Risk.

We are exposed to market risk from changes in foreign currency exchange rates and short-term interest rates. Market risks for changes in interest rates relate primarily to our debt obligations under our 2021 Credit Agreement. Foreign currency exchange risks are attributable to sales to foreign customers and purchases from foreign suppliers not denominated in our functional currency which is the U.S. Dollar ("USD") and include exposures primarily to the Canadian Dollar.

The Company periodically enters into derivative contracts with the objective of managing its financial and operational exposure arising from these risks by offsetting gains and losses on the underlying exposures with gains and losses on the financial instruments used to hedge them. We did not have any foreign currency derivative contracts outstanding at any time during the three-year period ended December 31, 2022. The maximum length of time over which we hedge our exposure to short-term interest rate risk is equal to the remaining term for the debt obligation being hedged. We had interest rate derivative contracts with a notional value of $20.0 million as of December 31, 2022 and 2021, respectively.

We do not enter into derivative financial instruments for speculative or trading purposes. Our hedging relationships are formally documented at the inception of the hedge, and hedges must be highly effective in offsetting changes to future cash flows on hedged transactions both at the inception of a hedge and on an ongoing basis to be designated for hedge accounting treatment. For derivative contracts which can be classified as a cash flow hedge, the effective portion of the change in the fair value of the derivative is recorded to accumulated other comprehensive loss in the consolidated balance sheet.  When the underlying hedge transaction is realized, the gain or loss included in accumulated other comprehensive income is recorded in earnings in the consolidated statement of income on the same line as the gain or loss on the hedged item attributable to the hedged risk.  We record the ineffective portion of interest rate hedging instruments, if any, to interest expense in the consolidated statements of income. See Note 9 to our consolidated financial statements for information related to the fair values of derivative instruments in our consolidated balance sheet as of December 31, 2022 and 2021 and information related to the effect of derivative instruments included in our consolidated income statement and statement of comprehensive income including the amount of unrealized gain associated with our interest rate derivatives reported in accumulated other comprehensive income that was reclassified into earnings during 2022 and 2021.

The Company uses an income approach to value derivative instruments, analyzing quoted market prices to calculate the forward values and then discounts such forward values to the present value using benchmark rates at commonly quoted intervals for the instrument’s full term.

In July 2017, Financial Conduct Authority (the authority that regulates LIBOR) previously announced its intent to stop compelling banks to submit rates for the calculation of LIBOR after 2021, and the administrator of LIBOR announced its intention to cease the publication of the one week and two-month USD LIBOR settings immediately following December 31, 2021, and the remaining USD LIBOR settings immediately following the LIBOR publication on June 30, 2023. The one-week and two-month USD LIBOR settings were last published on December 31, 2021. Additionally, it is expected that banks will no longer issue LIBOR-based debt after December 31, 2021. Accordingly, there is considerable uncertainty regarding the publication of such rates beyond these dates. The Alternative Reference Rates Committee ("ARRC") has proposed that the Secured Overnight Financing Rate ("SOFR") is the rate that represents best practice as the alternative to USD LIBOR for use in derivatives and other financial contracts that are currently indexed to USD LIBOR. ARRC has proposed a paced market transition plan to SOFR from USD LIBOR and organizations are currently working on industry-wide and company-specific transition plans as it relates to derivatives and cash markets exposed to USD LIBOR. At this time, it is not known whether or when SOFR or other alternative reference rates will attain market traction as replacements for LIBOR. The Company's 2021 Credit Agreement, discussed in Note 8 to the Consolidated Financial Statements, and the Company's interest rate swap agreements, discussed in Note 9 to the Consolidated Financial Statements, are indexed to USD LIBOR and management is monitoring this activity and evaluating the related risks.

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of InfuSystem Holdings, Inc. and its subsidiaries (the “Company”) as of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive income, stockholders’ equity, and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2022, in conformity with accounting principles generally accepted in the United States of America.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the Company's internal control over financial reporting as of December 31, 2022, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”) and our report dated March 16, 2023, expressed an adverse opinion thereon.

Basis for Opinion

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

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

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: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter 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.

Third-Party Payer Rental Revenue

As described in Note 2 and Note 4 of the Company’s consolidated financial statements, variable consideration related to third-party payer rentals is estimated as implied price concessions resulting from differences between the rates charged for services performed and the expected reimbursements for commercial payers and other implied customer concessions (“payer reimbursement rates”). Such payer reimbursement rates are based on historical collections with similar payers, aged accounts receivable by payer class and payer correspondence using the portfolio approach. For the year ended December 31, 2022, the Company’s consolidated revenues attributable to third-party payer rentals were $55.5 million. 

We identified the estimation of payer reimbursement rates used in the determination of variable consideration from third-party payer rental revenue as a critical audit matter. Significant assumptions, including rates charged and collection, are used to determine payer reimbursement rates. Auditing management’s estimates involved subjective auditor judgment due to the nature and extent of audit effort required to address these matters.

36

The primary procedures we performed to address this critical audit matter included:

•Testing the inputs to the payer reimbursement rates through tracing to source documents.

•Testing the calculation of payer reimbursement rates through checking the mathematical accuracy of the calculations.

•Evaluating management’s estimated payer reimbursement rates by performing a retrospective review of historical estimated payer reimbursement rates to actual reimbursements received.

Report of Independent Registered Public Accounting Firm

Shareholders and Board of Directors

InfuSystem Holdings, Inc.

Rochester Hills, Michigan

Opinion on Internal Control over Financial Reporting

We have audited InfuSystem Holdings, Inc.'s and its subsidiaries (the “Company”) internal control over financial reporting as of December 31, 2022, based on the criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (the "COSO criteria"). In our opinion, the Company did not maintain in all material respects, effective internal control over financial reporting as of December 31, 2022, based on the COSO criteria.

We do not express an opinion or any other form of assurance on management's statements referring to any corrective actions taken by the Company after the date of management's assessment.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated balance sheets of the Company as of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive income, stockholders' equity, and cash flows for each of the three years in the period ended December 31, 2022, and the related notes (collectively referred to as "the financial statements") and our report dated March 16, 2023, expressed an unqualified opinion thereon.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Item 9A, Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit of internal control over financial reporting in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the Company's annual or interim financial statements will not be prevented or detected on a timely basis. Material weaknesses were identified regarding the following:

1.Management's failure to design and implement effective controls over the completeness and accuracy of information used by control owners in the operation of certain controls across financial statement areas.

2.Management's failure to design and implement effective controls used in financial reporting processes, including general information technology controls over access rights within certain financial reporting and accounting applications which led to ineffective segregation of duties over certain business processes, the creation and review of journal entries, and account reconciliations.

3.Management's failure to design and implement effective controls over management's review of established pricing and contract terms to support recorded revenue and accounts receivable for the DME Services Direct Payer Rentals, DME Services Product Sales, DME Services - Service and ITS Direct payer Rentals revenue streams.

These material weaknesses were considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2022 consolidated financial statements, and this report does not affect our report dated March 16, 2023 on those consolidated financial statements.

38

Definition and Limitations of Internal Control over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

INFUSYSTEM HOLDINGS, INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.Basis of Presentation and Nature of Operations

InfuSystem Holdings, Inc. and its consolidated subsidiaries (the “Company”) are a leading national provider of infusion pumps and related products and services for patients in the home, oncology clinics, ambulatory surgery centers, and other sites of care from seven locations in the United States ("U.S.") and Canada. The Company provides products and services to hospitals, oncology practices and facilities and other alternate site health care providers. Headquartered in Rochester Hills, Michigan, the Company delivers local, field-based customer support, and also operates pump service and repair Centers of Excellence in Michigan, Kansas, California, Massachusetts, Texas and Ontario, Canada. InfuSystem Inc. (“ISI”) and First Biomedical, Inc. ("First Biomedical") are both operating subsidiaries of the Company.

The Company’s core service is to supply electronic ambulatory infusion pumps and associated disposable supply kits to oncology clinics, infusion clinics and hospital outpatient chemotherapy clinics to be utilized in the treatment of a variety of cancers including colorectal cancer, pain management and other disease states. The majority of the Company’s pumps are electronic infusion pumps. Smiths Medical, Inc. and Moog Medical Devices Group each supplied more than 10% of the ambulatory pumps purchased by the Company in 2022. The Company has a supply agreement in place with each of these suppliers. Certain “spot” purchases are made on the open market subject to individual negotiation. The Company also supplies Negative Pressure Wound Therapy (“NPWT”) medical equipment, as well as related disposables and ancillary supplies.

In addition, the Company sells or rents new and pre-owned pole-mounted and ambulatory infusion pumps to, and provides biomedical recertification, maintenance and repair services for oncology practices, as well as other alternate site settings including home care and home infusion providers, skilled nursing and acute care facilities, pain centers and others.

The Company purchases new and pre-owned pole-mounted and ambulatory infusion pumps from a variety of sources on a non-exclusive basis. The Company repairs, refurbishes and provides biomedical certification for the devices as needed. The pumps are then available for sale, rental or to be used within the Company’s ambulatory infusion pump management service.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).

2.Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and all wholly owned organizations. All intercompany transactions and account balances have been eliminated in consolidation.

Segments

The Company operates in two reportable segments, Integrated Therapy Services (“ITS”) and Durable Medical Equipment Services (“DME Services”) based on management's view of its business for purpose of evaluating performance and making operating decisions.

The Company’s approach is to make operational decisions and assess performance based on delivering products and services that together provide solutions to its customer base utilizing a functional management structure. Based upon this business model, the Company’s Chief Executive Officer, whom the Company has determined to be its chief operating decision-maker, reviews segment financial information. See Note 14 for segment disclosures.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements, including the notes thereto. The Company considers critical accounting policies to be those that require more significant judgments and estimates in the preparation of its consolidated financial statements, including the following: revenue recognition, leases, accounts receivable and allowance for doubtful accounts, income taxes, equity compensation valuations, and long-lived asset valuations. Management relies on historical experience and other assumptions believed to be reasonable in making its judgments and estimates. Actual results could differ materially from those estimates.

45

Business Combinations

The Company accounts for all business combinations using the acquisition method of accounting, which allocates the fair value of the purchase consideration to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions. The Company may utilize third-party valuation specialists to assist the Company in the allocation. For intangible assets, the Company typically uses the income approach to determine their estimated fair values. Key estimates and assumptions in that approach include the amount and timing of projected future cash flow, the discount rate selected to measure the risks inherent in those cash flows and the assessment of the asset's useful life. Initial purchase price allocations are subject to revision within the measurement period, not to exceed one year from the date of acquisition. Acquisition-related expenses and transaction costs associated with business combinations are expensed as incurred.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company maintains substantially all of its cash and cash equivalents primarily with two financial institutions that are insured with the Federal Deposit Insurance Corporation (“FDIC”). At times throughout the year, cash and cash equivalents balances might exceed FDIC insurance limits. Accounts at banks with an aggregate excess of the amount of outstanding checks over the cash balances are included in accounts payable in current liabilities in the consolidated balance sheet. At December 31, 2022, the Company did not have any cash equivalents.

Accounts Receivable and Allowance for Doubtful Accounts

Amounts billed that have not yet been collected that also meet the conditions for unconditional right to payment are presented as accounts receivable. Accounts receivable related to rental service and delivery of products are reported at their estimated transaction prices, inclusive of adjustments for variable consideration, based on the amounts expected to be collected from payers. The Company writes off accounts receivable once collection efforts have been exhausted and an account is deemed to be uncollectible. An allowance for doubtful accounts is established as a result of an adverse change in the Company’s payers’ ability to pay outstanding billings. The allowance for doubtful accounts was $1.1 million as of both December 31, 2022 and 2021.

Inventories

The Company’s inventories consist of disposable medical supplies, replacement parts and other supplies used in conjunction with medical equipment and are stated at the lower of cost (first-in, first-out basis) or net realizable value. Cost primarily represents the purchase price paid for the items on hand. The Company periodically performs an analysis of slow-moving inventory and records an adjustment to reflect the recoverable amount.

Medical Equipment

Medical Equipment (“Equipment”) consists of equipment that the Company purchases from third-parties and is (1) held for sale or rent, and (2) used in service to generate rental revenue. Equipment, once placed into service, is depreciated using the straight-line method over the estimated useful lives of the equipment which is typically seven years. The Company does not depreciate Equipment held for sale or rent. When Equipment in rental service assets are sold, or otherwise disposed, the cost and related accumulated depreciation are removed from the accounts and a gain or loss is recorded in the current period. The Company periodically performs an analysis to identify potentially missing Equipment and records a reserve equal to the underlying net book value, which was $2.3 million and $1.1 million as of December 31, 2022 and 2021, respectively. This amount approximates the accelerated depreciation the Company would recognize over the remaining useful lives of the assets. During the current period, the Company changed its estimate for missing pumps used by certain therapies by shortening the time estimate of when a pump is considered missing. As a result of this change in estimate, the Company increased the pump reserve as of December 31, 2022 and increased its cost of sales for the twelve months ended December 31, 2022 by $0.4 million. The Company performs a similar analysis of slow-moving Equipment for sale or rent and records a reserve, which was less than $0.1 million as of both December 31, 2022 and 2021.

Presentation of Medical Equipment in the Consolidated Statements

The Company purchases medical equipment directly for sale as well as medical equipment that is purchased for either rental or sale and that is unallocated at the time of purchase (“Unallocated Assets”). Management believes that the predominant source of revenues and cash flows from the Unallocated Assets is from rentals and most equipment purchased is likely to be

46

rented prior to being sold. The Company concluded that (i) the assets specifically supporting its two primary revenue streams should be separately disclosed on the balance sheet; (ii) the purchase and sale of Unallocated Assets should be classified solely in investing cash flows based on their predominant source while medical equipment purchased specifically for sales activity should be classified in operating cash flows; and (iii) other activities ancillary to the rental process should be consistently classified.

Property and Equipment

Property and equipment is stated at acquired cost and depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to seven years. Externally purchased information technology software and hardware are depreciated over three and five years, respectively. Leasehold improvements are amortized using the straight-line method over the life of the asset or the remaining term of the lease, whichever is shorter. Maintenance and minor repairs are charged to operations as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is recorded in the current period.

Goodwill

Goodwill is tested for impairment annually or more frequently when certain events or circumstances trigger a review. Management has the option to first assess qualitative factors such as current performance and overall economic conditions to determine whether or not it is necessary to perform a quantitative goodwill impairment test. If the Company chooses that option, then the Company would not be required to perform a quantitative goodwill impairment test unless the Company determines that, based on a qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the Company determines that an impairment is more likely than not, or if the Company chooses not to perform a qualitative assessment, the Company will then proceed with the quantitative assessment. Under the quantitative test, if the fair value of a reporting unit exceeds its carrying amount, then goodwill of the reporting unit is considered to not be impaired. If the carrying amount of the reporting unit exceeds its fair value, then an impairment loss is recognized in an amount equal to the excess, up to the value of the goodwill. The Company performed its annual impairment analysis by using a quantitative assessment as of October 31, 2022 and determined that there was no impairment.

Intangible Assets

Intangible assets consist of trade names, physician and customer relationships, unpatented technology, non-competition agreements and software. The Company amortizes the value assigned to the physician and customer relationships on a straight-line basis over the period of expected benefit, which ranges from fifteen to twenty years. The acquired physician and customer relationship base represents a valuable asset of the Company due to the expectation of future business opportunities to be leveraged from the existing relationship with each physician and customer. The Company has long-standing relationships with numerous oncology clinics, physicians, home care and home infusion providers, skilled nursing and acute care facilities, pain centers and others. The useful lives of these relationships are based on the expected attrition rates. Acquired software is amortized on a straight-line basis over the period of expected benefit, which ranges from three to five years. Acquired unpatented technology arose from recent acquisitions and is amortized on a straight-line basis over the period of expected benefit, which is seven years. This asset represents acquired knowledge of repair solutions that will be leveraged into opportunities into the acute care market. The non-competition agreements arose from recent acquisitions and are amortized on a straight-line basis over the terms of the agreements, which is five years. Trade names associated with the original acquisition of InfuSystem are not amortized.

Management tests indefinite life trade names for impairment annually or more frequently if deemed necessary. Management has the option of first performing the impairment test for intangible assets with indefinite lives on a qualitative basis, by evaluating factors to determine whether it is more likely than not that an impairment exists. If it is more likely than not that an impairment exists, or if the Company chooses not to perform a qualitative assessment, then a quantitative impairment test is performed. Impairment exists when the carrying amount of the intangible asset exceeds its fair value. If the carrying value of the intangible assets exceeds the fair value, an impairment loss is recognized in an amount equal to that excess. The Company performed its annual impairment analysis by using a quantitative assessment as of October 31, 2022 and determined that the fair value of the trade names with indefinite lives was greater than their carrying value, resulting in no impairment.

Software Capitalization and Depreciation

The Company capitalizes certain costs incurred in connection with obtaining or developing internal-use software, including payroll and payroll-related costs for employees who are directly associated with the internal-use software project, external direct costs of materials and services and interest costs while developing the software. Capitalized software costs are included in intangible assets, net and are amortized using the straight-line method over the estimated useful life of three to five

47

years. Capitalization of such costs ceases when the project is substantially complete and ready for its intended purpose. Costs incurred during the preliminary project and post-implementation stages, as well as software maintenance and training costs, are expensed in the period in which they are incurred. The Company did not capitalize any internal-use software for the year ended December 31, 2022, but did obtain and capitalize $0.3 million of internal-use software for the year ended December 31, 2021 in connection with the Company's acquisition of OB Healthcare Corporation. Amortization expense for capitalized software was $0.1 million in 2022, $1.6 million in 2021 and $1.9 million in 2020.

The Company assesses impairment indicators related to its internally-developed, internal-use software, specifically looking at the effectiveness and useful lives of each project and sub-project to determine if impairment indicators are present. For the year ended December 31, 2022, the Company assessed the impairment indicators and found none to be present.

Impairment of Long-Lived Assets

Long-lived assets held for use, which includes medical equipment in rental service, property and equipment and amortizable intangible assets, are reviewed for impairment when events or changes in circumstances indicate that their carrying value may not be recoverable. If an impairment indicator exists, the Company assesses the asset or asset group for recoverability. Recoverability of these assets is determined based upon the expected undiscounted future net cash flows from the operations to which the assets relate, utilizing management’s best estimates, appropriate assumptions and projections at the time. If the carrying value is determined not to be recoverable from future operating cash flows, the asset is deemed impaired and an impairment loss would be recognized to the extent the carrying value exceeded the estimated fair market value of the asset or asset group. For the years ended December 31, 2022, 2021 and 2020, respectively, the Company assessed the impairment indicators and found none to be present.

Leases

The Company accounts for leases following Accounting Standards Codification ("ASC") Topic 842, Leases,("Topic 842"). Under Topic 842, lessees are required to recognize a lease liability and right-of-use asset (“ROU asset”) for all leases and to disclose key information about leasing arrangements. Additionally, leases are classified as either financing or operating; the classification determines the pattern of expense recognition and classification within the statement of operations. The Company elected to apply its lease accounting policy only to leases with a term greater than twelve months.

Topic 842 provides practical expedients for an entity’s ongoing accounting. The Company elected the “combining lease and non-lease components” practical expedient and also elected to apply the short-term lease recognition exemption to certain leases; therefore, the Company did not recognize ROU assets and lease liabilities for these leases.

In adopting Topic 842, the Company determined and will continue to determine whether an arrangement is a lease at inception. The Company’s operating leases are primarily for office space, service facility centers and equipment under operating lease arrangements that expire at various dates over the next nine years. The Company’s leases do not contain any restrictive covenants. The Company’s office leases generally contain renewal options for periods ranging from one to five years. Because the Company is not reasonably certain to exercise these renewal options, the options are not considered in determining the lease term, and payments associated with the option years are excluded from lease payments. The Company’s office leases do not contain any material residual value guarantees. The Company’s equipment leases generally do not contain renewal options. The Company is not reasonably certain to exercise the renewal options for those equipment leases that do contain renewal options, thus, the options are not considered in determining the lease term and payments associated with the option years are excluded from lease payments.

For the Company’s equipment leases, the Company used and will use the implicit rate in the lease as the discount rate, when available. Otherwise, the Company uses its incremental borrowing rate as the discount rate. For the Company’s office leases, the implicit rate is typically not available, so the Company used and will use its incremental borrowing rate as the discount rate. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments. The Company’s lease agreements include both lease and non-lease components.

Payments due under the Company’s operating leases include fixed payments as well as variable payments. For the Company’s office leases, variable payments include amounts for the Company’s proportionate share of operating expenses, utilities, property taxes, insurance, common area maintenance and other facility-related expenses. For the Company’s equipment leases, variable payments may consist of sales taxes, property taxes and other fees.

48

Revenue Recognition

Revenue is recognized at the time and in an amount that reflects the consideration expected to be received for the performance obligations that have been provided. ASC Topic 606 – Revenue from Contracts with Customers (“ASC 606”) defines contracts as written, oral and through customary business practice. Under this definition, the Company considers contracts to be created at the time that the rental service is authorized or an order to purchase product is agreed upon regardless of whether or not there is a written contract.

The Company has three separate and distinct performance obligations offered to its customers: a rental service performance obligation, a product sale performance obligation and a service performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account for revenue recognition under ASC 606. These performance obligations are related to separate revenue streams and at no point are they combined into a single transaction. Sources of net revenues include commercial insurance payers, government insurance payers, medical facilities and patients.

The Company generates its revenues from the rental of infusion pumps to its customers and from product sales and services. For the rental service performance obligation, revenue is based on its standalone price, determined by using reimbursement rates established by third-party payer or other contracts. Revenue is recognized in the period in which the related performance obligation is satisfied, which is typically at the point in time that a patient concludes a treatment, or in certain arrangements, based on the number of pumps that a facility has onsite. The Company’s revenues related to product sales are recognized at the time that control of the product has been transferred to the customer; either at the time the product is shipped or the time the product has been received by the customer, depending on the delivery terms. The Company does not commit to long-term contracts to sell customers a certain minimum quantity of products. The Company's revenues related to services are recognized at the time that the service work has been completed.

The Company employs certain significant judgments to estimate the dollar amount of revenue, and related concessions, allocated to the rental service. These judgments include, among others, the estimation of variable consideration. Variable consideration, specifically related to the Company’s third-party payer rental revenues, is estimated as implied price concessions resulting from differences between the rates charged for services performed and the expected reimbursements for commercial payers and other implied customer concessions. The estimates for variable consideration are based on historical collections with similar payers, aged accounts receivable by payer class and payer correspondence using the portfolio approach, which provide a reasonable basis for estimating the variable portion of a transaction. The Company doesn’t believe it is probable that a significant reversal of revenue will occur in future periods because (i) there is no significant uncertainty about the amount of considerations that are expected to be collected based on collection history and (ii) the large number of sufficiently similar contracts allows the Company to adequately estimate the component of variable consideration.

Net revenues are adjusted when changes in estimates of variable consideration occur. Changes in estimates typically arise as a result of new information obtained, such as actual payment receipt or denial, or pricing adjustments by payers. Subsequent changes to estimates of transaction prices are recorded as adjustments to net revenue in the period of the change. Subsequent changes that are determined to be the result of an adverse change in the payer’s ability to pay are recorded as an allowance for doubtful accounts.

Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenues and accounts receivable at their net realizable values. Inherent in these estimates is the risk that the estimates will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payers may result in adjustments to amounts originally recorded. Due to continuing changes in the health care industry and third-party reimbursement, it is possible that management’s estimates could change in the near term, which could have a material impact on the Company’s results of operations and cash flows.

Cost of Revenues

Cost of revenues include the costs of servicing and maintaining pumps, products and services sold, shipping and other direct and indirect costs related to net revenues. Shipping and handling costs incurred after control over a product has transferred to a customer are accounted for as a fulfillment cost.

Customer Concentration

As of December 31, 2022, the Company had contracts with nearly 800 third-party payer networks, an increase of 4% over the prior year period. Material terms of contracts with third-party payer organizations are typically a pre-negotiated fee

49

schedule rate or a then-current proprietary fee schedule rate for equipment and supplies provided. The majority of these contracts generally provide for a term of one year, with automatic one-year renewals, unless the Company or the contracted payer elect not to renew. The Company also contracts with various other third-party payer organizations, Medicaid, commercial Medicare replacement plans, self-insured plans, facilities of its Medicare patients and numerous other insurance carriers. No single payer or customer represented more than 10% of the Company's net revenue in 2022, 2021 or 2020.

Income Taxes

The Company recognizes deferred income tax liabilities and assets based on (i) the differences between the financial statement carrying amounts and the tax basis of assets and liabilities, using enacted tax rates in effect in the years the differences are expected to reverse and (ii) the tax credit carryforwards. Deferred income tax (expense) benefit results from the change in net deferred tax assets or deferred tax liabilities. A valuation allowance is recorded when it is more likely than not that some or all of any deferred tax assets will not be realized.

Provisions for federal, state and foreign taxes are calculated based on reported pre-tax earnings based on current tax law and include the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Certain items of income and expense are recognized in different time periods for financial reporting than for income tax purposes; thus, such provisions differ from the amounts currently receivable or payable.

The Company follows a two-step approach for recognizing uncertain tax positions. First, it evaluates the tax position for recognition by determining if the weight of available evidence indicates it is more-likely-than-not that the position will be sustained upon examination. Second, for positions that are determined are more-likely-than-not to be sustained, it recognizes the tax benefits as the largest benefit that has a greater than 50% likelihood of being sustained. The Company establishes a reserve for uncertain tax positions liability that is comprised of unrecognized tax benefits and related interest and penalties. The Company adjusts this liability in the period in which an uncertain tax position is effectively settled, the statute of limitations expires for the relevant taxing authority to examine the tax position, or more information becomes available.

The Company adopted Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, in the fourth quarter of 2019. This guidance simplifies various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The guidance was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption was permitted, including adoption in any interim period for which financial statements had not yet been issued. Certain amendments may have been applied on a retrospective, modified retrospective or prospective basis. As permitted, the Company elected to early adopt this guidance for the year ended December 31, 2019. The adoption of this guidance did not have a significant impact on the Company’s financial statements and primarily resulted in the reclassification of an immaterial amount from non-income tax expense to income tax expense related to the accounting for franchise taxes, with no impact to the Company’s consolidated net income, equity or cash flows.

Treasury Stock

The Company periodically repurchases shares of its common stock. These repurchases take place either as part of a board-authorized program, which may include open market transactions or privately negotiated transactions and may be made under a Rule 10b5-1 plan, or in targeted stock purchase agreements approved by the board. Treasury stock is accounted for using the par value method. In 2021, the Company retired the approximately 3,500,000 shares that were previously held in treasury. As of December 31, 2022, the Company does not have any shares being held in treasury.

Share-Based Payments

The Company determines the fair value of stock option awards, restricted stock awards and stock appreciation rights (collectively, “Share-Based Awards”) on the date of grant using either the grant date price of the Company's common stock or option-pricing models which are affected by the Company’s stock price, as well as assumptions regarding a number of other inputs using the Black-Scholes pricing model. These variables include the Company’s expected stock price volatility over the expected term of the Share-Based Awards, actual and projected employee stock option exercise behaviors, risk-free interest rates and expected dividends. The expected volatility is based on the historical volatility. The expected term represents the period over which the Share-Based Awards are expected to be outstanding. The dividend yield is an estimate of the expected dividend yield on the Company’s stock. The risk-free rate is based on U.S. Treasury yields in effect at the time of the grant for the expected term of the Share-Based Awards. Forfeitures are recognized as they occur. All Share-Based Awards are amortized based on their graded vesting over the requisite service period of the awards. Compensation costs are recognized over the requisite service period using the accelerated method and included in general and administrative expenses.

50

Additionally, the Company also determines the fair value of performance-based restricted stock units (“PSUs”) based upon the type of performance measure. These awards typically vest after the Company’s achievement of either a specific Company performance metric or when the market value of the Company’s stock meets a specific metric such as when the closing price of the Company's stock reaches a target value for a minimum number of consecutive trading days. Under Financial Accounting Standards Board (“FASB”) ASC Topic 718, the provisions of the PSUs that vest upon achievement of a target market value are considered a market condition, and therefore the effect of that market condition is reflected in the grant date fair value for this type of award. A third-party valuation expert was engaged to prepare a “Monte Carlo simulation” to account for the market condition to assist management in its conclusion of fair value. That simulation takes into account the beginning stock price of the Company’s common stock, the expected volatilities for the Company’s stock price and the expected risk-free rate of return. The single grant-date fair value computed by this valuation method is recognized by the Company in accounting for the awards regardless of the actual future outcome of the market condition. Compensation costs are accelerated if the market condition is satisfied prior to the end of the service period derived under the Monte Carlo simulation. The grant date fair value of the other PSUs is calculated as the closing price of the Company’s common stock on the grant date multiplied by the number of shares estimated to be delivered subject to the award terms. Company performance measure goals are considered a performance condition and the timing and amount of compensation cost for those PSUs corresponds with management’s expectation of the probable outcome of the performance conditions as of the grant date and during the vesting period.

Deferred Debt Issuance Costs

Capitalized debt issuance costs as of December 31, 2022 and 2021 relate to the Company’s credit facility. The costs related to the agreement are netted against current and non-current debt. The Company amortizes these costs using the interest method through the maturity date of the underlying debt.

Earnings Per Share

The Company reports its earnings per share which includes the presentation of both basic and diluted earnings per share on the statements of operations. The diluted weighted average common shares include adjustments for the potential effects of outstanding stock options but only in the periods in which such effect is dilutive under the treasury stock method. Included in our basic and diluted weighted average common shares are those stock options and restricted stock awards due to participants granted from the 2014 and 2021 stock incentive plans. Anti-dilutive stock awards are comprised of stock options and unvested restricted stock awards, which would have been anti-dilutive in the application of the treasury stock method. In periods where the Company records a net loss, the diluted per share amount is the same as the basic per share amount.

In accordance with this topic, the following table reconciles income and share amounts utilized to calculate basic and diluted net income per common share:

	Years Ended December 31,
	2022		2021		2020
Numerator (in thousands):
Net income:	$	18	$	1,420	$	17,332
Denominator:
Weighted average common shares outstanding:
Basic	20,648,818		20,519,958		20,106,940
Dilutive effect of common stock equivalents	898,488		1,529,701		1,610,276
Diluted	21,547,306		22,049,659		21,717,216

Stock options of 1,085,855, 368,056 and 18,321 shares were not included in the calculation for the years ended December 31, 2022, 2021 and 2020, respectively, because they would have an anti-dilutive effect.

Derivatives

The Company recognizes all derivative financial instruments as cash flow hedges which are shown as either assets or liabilities on the Company’s consolidated balance sheets at fair value. For derivative contracts which can be classified as a cash flow hedge, the effective portion of the change in fair value of the derivative is recorded to accumulated other comprehensive income (“AOCI”) in the consolidated balance sheets. The underlying hedge transaction is realized when the interest payments

51

on debt are accrued; the applicable amount of gain or loss included in AOCI is reclassified into earnings in the consolidated statements of operations on the same line as the gain or loss on the hedged item attributable to the hedged risk. The cash flows from derivatives are classified as operating activities.

The Company maintains a policy of requiring that all derivative instruments be governed by an International Swaps and Derivatives Association Master Agreement and settles on a net basis.

The fair values of the Company’s derivative financial instruments are categorized as Level 2 of the fair value hierarchy as the values are derived using the market approach based on observable market inputs including quoted prices of similar instruments and interest rate forward curves.

Fair Value of Financial Instruments

The carrying amounts reported in the consolidated balance sheets as of December 31, 2022 and 2021 for cash, accounts receivable, accounts payable and other current liabilities approximate fair value because of the short-term nature of these instruments (Level I). The carrying value of the Company’s long-term debt with variable interest rates approximates fair value based on instruments with similar terms (Level II).

The Company has adopted ASC 820, Fair Value Measurements, which defines fair value, establishes a framework for assets and liabilities being measured and reported at fair value and appends disclosures about fair value measurements.

For financial assets and liabilities measured at fair value on a recurring basis, fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value as follows:

Level I:    quoted prices in active markets for identical instruments;

Level II:    quoted prices in active markets for similar instruments, quoted prices for identical instruments in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the instrument; and

Level III:    significant inputs to the valuation model are unobservable.

Recent Accounting Pronouncements and Developments

The Company has adopted ASU 2020-04, Reference Rate Reform (Topic 848), which contains optional expedients for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Inter-bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848): Scope." This ASU clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The Company has elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments (Topic 326) Credit Losses”. Topic 326 changes the impairment model for most financial assets and certain other instruments. Under the new standard, entities holding financial assets and net investment in leases that are not accounted for at fair value through net income are to be presented at the net amount expected to be collected. An allowance for credit losses will be a valuation account that will be deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. Topic 326 was originally effective as of January 1, 2020, although in November 2019, the FASB delayed the effective date until fiscal years beginning after December 15, 2022 for SEC filers eligible as of the FASB's deferral date to be smaller reporting companies under the SEC’s definition. The Company qualified as a smaller reporting company in November 2019 when the FASB delayed the effective date of Topic 326. Early adoption is permitted. The Company is currently evaluating the impact of Topic 326 on its consolidated balance sheets, statements of operations, statements of cash flows and related disclosures.

3.Business Combinations

Acquisitions Accounted for Using the Purchase Method

On January 31, 2021, the Company acquired the business and the majority of the assets of FilAMed, a privately-held biomedical services company based in Bakersfield, California. In becoming a part of the Company's DME Services segment, this acquisition supplemented the Company’s existing biomedical recertification, maintenance and repair services for acute care facilities and other alternate site settings including home care and home infusion providers, skilled nursing facilities, pain centers and others.

On April 18, 2021, the Company acquired the business and substantially all of the assets of OB Healthcare Corporation (“OB Healthcare”), a privately-held biomedical services company based in Austin, Texas. OB Healthcare specializes in on-site repair, preventative maintenance, and device physical inventory management to hospitals and healthcare systems nationwide. The acquisition further develops and expands InfuSystem’s DME Services segment and complements the Company’s purchase of FilAMed.

The results of operations for FilAMed and OB Healthcare are included in the Company’s consolidated statements of operations from the respective closing dates.

Purchase Price Allocation

Pursuant to ASC Topic 805, “Business Combinations,” the purchase price for each of the acquisitions was allocated to the assets acquired and liabilities assumed based upon their estimated fair values as of the respective acquisition dates. The purchase price allocations were primarily based upon a valuation using management’s estimates and assumptions. The purchase price allocation was completed for FilAMed and OB Healthcare as of December 31, 2021. The following tables summarize the consideration paid and the allocation of the purchase price to the fair values of the assets acquired and liabilities assumed as of the respective acquisition dates for both FilAMed and OB Healthcare (in thousands):

	FilAMed		OB Healthcare		Total Consideration

The amount of acquisition costs for both transactions was $0.2 million and is included in general and administrative expenses for the year ended December 31, 2021.

The Company fully paid all consideration for FilAMed as of December 31, 2021. On the OB Healthcare acquisition date, the Company made an initial cash payment of $6.1 million with subsequent cash payments of $0.4 million during the year ended December 31, 2021 and had an additional estimated amount due to the seller for contingent consideration of $0.8 million,

53

which was recorded in the balance sheet under the heading for other current liabilities. The contingent consideration arrangement, as amended, required the Company to pay OB Healthcare $0.8 million if certain written contracts were executed. As of December 31, 2022, the requirement under the contingent consideration arrangement had been satisfied and the Company made the required payment.

The following table shows the breakdown of the identified intangible assets acquired into major intangible asset classes for both acquisitions:

	Acquisition Date Fair Value (Thousands)		Weighted-Average Amortization Period (Years)
Customer relationships	$	2,300	15
Unpatented technology	943		7
Non-competition agreements	472		5
Internal-use software	300		5
Total intangible assets (a)	$	4,015	11.2
(a) There was no residual value, renewal terms or extensions associated with any intangible assets acquired.

The goodwill acquired consists of expected synergies from combining operations of FilAMed and OB Healthcare with the DME Services segment as well as their respective assembled workforce who have specialized knowledge and experience. All of the goodwill is deductible for tax purposes.

The pump reserve for medical equipment in rental service represents an estimate for medical equipment that is considered to be missing. The reserve calculated is equal to the net book value of assets that have not returned from the field within a certain timeframe. During the current period, the Company changed its estimate for missing pumps used by certain therapies by shortening the time estimate of when a pump is considered missing. As a result of this change in estimate, the Company increased the pump reserve as of December 31, 2022 and increased its cost of sales for the twelve months ended December 31, 2022 by $0.4 million.

8.Debt

On February 5, 2021, the Company entered into a Credit Agreement (the “2021 Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent (the “Agent”), sole bookrunner and sole lead arranger, and the lenders party thereto. The borrowers under the 2021 Credit Agreement are the Company, InfuSystem Holdings USA, Inc. (“Holdings”), ISI, First Biomedical, and IFC LLC (“IFC” and, collectively with the Company, Holdings, ISI and First Biomedical, the “Borrowers”).

The 2021 Credit Agreement provides for a revolving credit facility (the “Revolving Facility”) of $75.0 million, maturing on February 5, 2026. The Revolving Facility may be increased by $25.0 million, subject to certain conditions, including the consent of the Agent and obtaining necessary commitments. The lenders under the 2021 Credit Agreement may issue up to $7.0 million in letters of credit subject to the satisfaction of certain conditions. On February 5, 2021, the Borrowers made an initial borrowing of $30.0 million under the Revolving Facility. Proceeds from the loan, along with approximately $8.2 million in cash, were used to repay all amounts due under the Company’s then existing credit facility dated March 23, 2015 (the “2015 Credit Agreement”).

The 2021 Credit Agreement has customary representations and warranties. The ability to borrow under the facility is subject to ongoing compliance with a number of customary affirmative and negative covenants, including limitations on indebtedness, liens, mergers, acquisitions, investments, asset sales, affiliate transactions and restricted payments, as well as financial covenants, including the following:

•a minimum fixed charge coverage ratio (defined as the ratio of consolidated EBITDA (as defined in the 2021 Credit Agreement) less 50% of depreciation expense), to consolidated fixed charges (as defined in the 2021 Credit Agreement)) for the prior four most recently ended calendar quarters of 1.20 to 1.00; and

•a maximum leverage ratio (defined as total indebtedness to EBITDA for the prior four most recently ended calendar quarters) of 3.50 to 1.00.

The 2021 Credit Agreement includes customary events of default. The occurrence of an event of default will permit the lenders to terminate commitments to lend under the Revolving Facility and accelerate payment of all amounts outstanding thereunder.

Simultaneous with the execution of the 2021 Credit Agreement, the Company entered into a Pledge and Security Agreement to secure repayment of the obligations of the Borrowers. Under the Pledge and Security Agreement, each Borrower has granted to the Agent, for the benefit of various secured parties, a first priority security interest in substantially all of the personal property assets of each of the Borrowers, including the shares of each of Holdings, ISI and First Biomedical and the equity interests of IFC.

On February 5, 2021, in connection with the execution and closing of the 2021 Credit Agreement, the Company, along with its wholly owned subsidiaries as borrowers, terminated the 2015 Credit Agreement. All outstanding loans under the 2015 Credit Agreement have been repaid and all liens under the 2015 Credit Agreement have been released, except that a letter of credit originally issued under the 2015 Credit Agreement in the amount of approximately $0.8 million was transferred to the 2021 Credit Agreement.

The 2021 Credit Agreement was accounted for as a debt modification that resulted in a small increase to deferred debt issuance costs. As of December 31, 2022, the Company was in compliance with all debt-related covenants under the 2021 Credit Agreement.

On April 15, 2019, the Company sold for $2.0 million and immediately leased back certain medical equipment in rental service to a third party specializing in such transactions. The leaseback term was 36 months. Because the arrangement contains a purchase option that the Company is reasonably certain to exercise, this transaction did not qualify for the sale-leaseback accounting under ASC 842. The medical equipment remains recorded on the accompanying condensed consolidated balance sheet and the proceeds received have been classified as an other financing liability. During the fourth quarter of 2021, the Company recorded an additional $0.2 million of interest expense to reflect the amount expected to be paid upon the exercise of the purchase option at the end of its other financing transaction. As of December 31, 2022, all amounts owed under this arrangement had been paid.

As of December 31, 2022, amounts outstanding under the Revolving Facility provided under the 2021 Credit Agreement bear interest at a variable rate equal to, at the Company’s election, a LIBO Rate for Eurodollar loans or an Alternative Base Rate for ABR loans, as defined by the 2021 Credit Agreement, plus a spread that will vary depending upon the Company’s leverage ratio. The spread ranges from 2.00% to 3.00% for Eurodollar Loans and 1.00% to 2.00% for base rate loans. The weighted-average Eurodollar loan rate at December 31, 2022 was 6.52% (LIBO of 4.27% plus 2.25%). The actual ABR loan rate at December 31, 2022 was 8.75% (lender’s prime rate of 7.50% plus 1.25%).

9.Derivative Financial Instruments and Hedging Activities

In February 2021, the Company adopted a derivative investment policy which provides guidelines and objectives related to managing financial and operational exposures arising from market changes in short term interest rates. In accordance with this policy, the Company can enter into interest rate swaps or similar instruments, will endeavor to evaluate all the risks inherent in a transaction before entering into a derivative financial instrument and will not enter into derivative financial instruments for speculative or trading purposes. Hedging relationships are formally documented at the inception of the hedge and hedges must be highly effective in offsetting changes to future cash flows on hedged transactions at the inception of a hedge and on an ongoing basis to be designated for hedge accounting treatment.

The Company is exposed to interest rate risk related to its variable rate debt obligations under the 2021 Credit Agreement. In order to manage the volatility in interest rate markets, in February 2021, the Company entered into two interest rate swap agreements to manage exposure arising from this risk. On a combined basis, the agreements have a constant notional amount over a 5-year term that ends on February 5, 2026. The agreements both pay the Company 30-day LIBOR on the notional amount and the Company pays a fixed rate of interest equal to 0.73%. These derivative instruments are considered cash flow hedges. The Company does not have any other derivative financial instruments.

(a) At December 31, 2022 and 2021, this includes state and local net operating losses of $1.2 million and $1.3 million, respectively.

The Company’s U.S. federal net operating loss carryforward for tax purposes was $35.7 million at December 31, 2022, resulting in a federal deferred tax asset of $7.5 million. Approximately $29.1 million of the Company’s U.S. federal net operating loss carryforwards will begin to expire in various years beginning in 2031. $6.6 million of U.S. federal net operating loss carryforwards have an indefinite life. The Company’s state net operating loss carryforward of approximately $1.2 million is comprised of various jurisdictions. These state net operating losses can be used for a period of 5 to 20 years and vary by state, and if unused, begin to expire in 2023, though a substantial portion expires beyond 2023. Approximately $0.1 million of the state net operating loss carryforwards have an indefinite life. Tax benefits of operating loss and tax credit carryforwards are

61

evaluated on an ongoing basis, including a review of historical and projected future operating results, the eligible carryforward period, and other circumstances.

The Company continues to monitor shifts in past ownership (as defined under Section 382 of the Code).

In the fourth quarter of 2020, it was determined that the valuation allowance against the U.S. federal and state deferred taxes was no longer required and the valuation allowance of $11.2 million that existed was released. The Company’s realization of its deferred tax assets is dependent upon many factors, including, but not limited to, the Company’s ability to generate sufficient taxable income. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. At December 31, 2022 and 2021, cumulative income in recent years and projected future taxable income is the basis for the Company’s assessment that the deferred tax assets do not require a valuation allowance.

The Company had no uncertain tax positions for the years ended December 31, 2022 and 2021.

The Company is subject to taxation for Federal and various state jurisdictions in the U.S. and Canada. The Federal income tax returns of the Company for the years 2019 through 2022 are open to examination by the Internal Revenue Service. The Company was under audit with the Internal Revenue Service in relation to the Company’s 2018 federal income tax return and the audit was closed on December 15, 2021. The state income tax returns and other state tax filings of the Company are subject to examination by the state taxing authorities, for various periods generally up to four years after they are filed. Canadian income tax returns of the Company for the years 2018 through 2022 are subject to examination by the Canada Revenue Agency.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security ("CARES") Act was enacted in response to the COVID-19 pandemic. The CARES Act among other things, allows employers to defer the deposit and payment of the employer's share of Social Security taxes. The Company, under the CARES Act, deferred paying $0.7 million of applicable gross payroll taxes as of December 31, 2020, which was included in other liabilities. The $0.7 million balance of the deferred Social Security taxes was paid in two annual installments during the years ending December 31, 2021 and 2022, respectively. On April 15, 2020, the Company received a $4.1 million loan under the Federal Paycheck Protection Program (“PPP”) created under the CARES Act. In response to revised eligibility guidelines announced by the U.S. Small Business Administration shortly thereafter, the Company repaid this loan in full on May 7, 2020.

11.Commitments and Contingencies

From time to time in the ordinary course of its business, the Company may be involved in legal and regulatory proceedings, the outcomes of which may not be determinable. The results of litigation and regulatory proceedings are inherently unpredictable. Any claims against the Company, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time and result in diversion of significant resources. The Company is not able to estimate an aggregate amount or range of reasonably possible losses for those legal matters for which losses are not probable and estimable, primarily for the following reasons: (i) many of the relevant legal proceedings are in preliminary stages, and until such proceedings develop further, there is often uncertainty regarding the relevant facts and circumstances at issue and potential liability; and (ii) many of these proceedings involve matters of which the outcomes are inherently difficult to predict. The Company has insurance policies covering potential losses where such coverage is cost effective.

The Company is not at this time involved in any proceedings that the Company currently believes could have a material effect on the Company’s financial condition, results of operations or cash flows.

12.Leases

The Company has historically entered into a number of lease agreements under which the Company is the lessee for equipment and office leases.

13.Share-Based Compensation

Stock Incentive Plan

The Company has various stock option and stock-based incentive plans and agreements whereby equity based awards are granted to certain employees, directors and others approved by the Company’s Board of Directors (the “Board”) or Compensation Committee. Grants may be made in the form of stock options, restricted stock awards ("RSUs" or "RSAs"),

63

performance-based restricted stock units ("PSU's), unrestricted common stock, stock appreciation rights (“SARs”) in addition to other award types. Stock options are granted with an exercise price at, or above, fair market value on the date of grant, generally expire in 5 to 10 years from the grant date and generally become exercisable over a period of up to 3 years. RSUs generally become vested over a period of up to three years. PSUs generally become vested over a period of up to three years based on the performance of a specific achievement. Awards typically vest and are issued only if the participants remain employed by the Company through the vesting date. Common stock issued under these awards are issued from shares reserved under the Company’s plan described below.

On May 18, 2021, the Company’s Board adopted the 2021 Equity Incentive Plan (the “2021 Plan”). The 2021 Plan was approved by the Company’s shareholders at the 2021 Annual Meeting on May 18, 2021 and became effective at that time. The 2021 plan supersedes the 2014 Amended and Restated Stock Incentive Plan (the "2014 Plan"). The 2021 Plan provided for the issuance of a maximum of 2,500,000 shares of common stock in connection with the grant of stock-based or stock-denominated awards. Reductions in the available share limit associated with these grants are based on a fungible ratio of 1:1 for stock options and stock appreciation rights and 2:1 for all other types of awards. Any shares subject to an award that expires or is cancelled, forfeited, or terminated without issuance of the full number of shares of stock to which the award related again become available for issuance under the limit. As of December 31, 2022, a total of 808,799 common shares remained available for future grant under the 2021 Plan. This amount reflects reductions from the original limit for grants reflective of the respective fungible ratios. The available amount also reflects the maximum potential share issuance potential in the case of performance grants that provide for variable share payouts.

On April 23, 2014, the Company’s Board adopted the 2014 Plan. The 2014 Plan was approved by the Company’s shareholders at the 2014 Annual Meeting and became effective as of the date it was adopted by the Board of Directors. The 2014 Plan provided for the issuance of a maximum of 2,000,000 shares of common stock in connection with the grant of stock-based or stock-denominated awards. On July 19, 2018, the Company’s stockholders approved the reservation of an additional 1,000,000 shares to be issued under the 2014 Plan. On May 15, 2019, the Company’s stockholders approved the reservation of an additional 1,000,000 shares to be issued under the 2014 Plan. The 2021 Plan replaces and supersedes the 2014 Plan, so as of the adoption date of the 2021 Plan, no common shares remained available for future grant under the 2014 Plan.

Stock-Based Compensation Expense

All stock option awards are amortized based on their graded vesting over the requisite service period of the awards. Compensation costs are recognized over the requisite service period using the accelerated method and included in general and administrative expenses.

The following table presents the total stock-based compensation expense, which is included in selling, general and administrative expenses (in thousands):

	Years Ended December 31,
	2022		2021		2020
Restricted share expense	$	2,683	$	4,491	$	1,687
Stock option and SARs expense	1,142		1,913		923
Total stock-based compensation expense	$	3,825	$	6,404	$	2,610
Tax benefit related to stock-based compensation	$	857	$	2,234	$	1,652

Shares Forgone to Satisfy Minimum Statutory Withholdings

During the years ended December 31, 2022, 2021 and 2020, shares of common stock were issued to employees and directors as their restricted stock awards vested or stock options were exercised. Under the terms of the Company’s stock plans, at the election of each employee, the Company can authorize a net settlement of distributable shares to employees in order to satisfy an individual employees' tax withholding obligations. For the years ended December 31, 2022, 2021 and 2020, the Company received 136,718 shares, 57,067 shares and 146,763 shares, respectively, from employees for tax withholding obligations.

Restricted Stock Awards

Restricted stock awards entitle the holder to receive, upon meeting certain time-based vesting criteria, a specified number of shares of the Company’s common stock. Stock-based compensation cost of restricted stock awards is measured by the market value of the Company’s common stock on the date of grant.

64

The following table summarizes the Company’s restricted share activity, excluding the Company’s employee stock purchase plan:

	Number of shares	Weighted average grant date fair value
Unvested at December 31, 2021	290,942	$	15.61
Granted	340,677	9.44
Vested	(25,583)	15.43
Vested shares forgone to satisfy minimum statutory withholding	(16,982)	15.43
Forfeitures	(54,974)	14.11
Unvested at December 31, 2022	534,080	$	11.85

	Year Ended December 31,
	2022		2021		2020
Weighted average grant date fair value of awards granted	$	9.44	$	18.85	$	10.12
Total fair value of shares vested	$	260,112	$	920,125	$	367,273
Total fair value of shares forgone to satisfy minimum statutory withholding	$	172,662	$	32,282	$	62,479

As of December 31, 2022, there was $3.2 million of pre-tax total unrecognized compensation cost related to non-vested restricted stock awards, which will be adjusted for future forfeitures, if any. The Company expects to recognize such cost over a weighted average period of two years

Performance-Based Restricted Stock Units

During the year ended December 31, 2022, the Company granted approximately 53,864 PSUs and during the year ended December 31, 2021, the Company granted approximately 127,476 PSUs. PSUs entitle the holder to receive, upon meeting certain performance-based vesting criteria, a specified number of shares of the Company’s common stock. These awards typically vest after the Company’s achievement of either a Company-based performance metric, such as the achievement of a certain amount of net revenue during a specified period, coupled with a time-based vesting criteria or based on a market based metric of the Company’s stock, such as when the trading price reaches a target value for a minimum number of consecutive trading days. All of the PSUs granted in 2022 and 2021 are earned based on specified Company-based performance measure conditions. In the case of the market-based metric, awards are paid in stock immediately upon achievement of the performance condition or expire without any payment after the third anniversary of the grant date. In the case of the specified Company-based performance measure, awards can be earned at an amount that varies by award between 93% to 100% of the target number of shares for achieving a minimum threshold below the target or up to 200% of the target number of shares for exceeding the target, with a linear adjustment between threshold and target or between target and stretch performance goals.

The following table summarizes the Company’s PSU activity:

	Number of shares	Weighted average grant date fair value
Unvested at December 31, 2021	239,976	$	14.74

Total fair value of shares forgone to satisfy minimum statutory withholding	$	506,036	$	1,078,747	N/A

As of December 31, 2022, there was no pre-tax total unrecognized compensation cost related to non-vested PSUs, which will be adjusted for changes to management’s expectations of the probable outcomes of the performance conditions, if any.

Employee Stock Purchase Plan

In May 2014, the Company received approval from stockholders to adopt an employee stock purchase plan ("ESPP") effective October 2014 (collectively the “Original ESPP”). Under the Original ESPP, 200,000 shares of common stock were authorized for purchase by eligible employees at a 15% discount through payroll deductions during the six-month offering periods. Shares were purchased in whole numbers and generally would be the last day of the offering period. In September 2016, the Company received approval from shareholders for an additional 350,000 shares. No employee may purchase more than $25,000 worth of fair market value shares in any calendar year. As allowed under the ESPP, a participant may elect to withdraw from the plan, effective for the purchase period in progress at the time of the election with all accumulated payroll deductions returned to the participant at the time of withdrawal. As of December 31, 2022, there were 95,379 shares remaining available for future issuance. The following table summarizes the activity relating to the Company’s ESPP program:

	Years Ended December 31,
	2022		2021		2020
Compensation expense	$	229,064	$	173,561	$	108,589
Shares of stock sold to employees	60,673		31,624		30,012
Weighted average fair value per ESPP award	$	11.53	$	16.95	$	7.43

Stock Options

The Company calculates the fair value of stock option awards using the Black-Scholes option pricing model, which incorporates various assumptions including volatility, expected term, risk-free interest rates and dividend yields. The expected volatility assumption is based on historical volatility of the Company’s common stock over the most recent period commensurate with the expected life of the stock option granted. The Company uses historical volatility because management believes such volatility is representative of prospective trends. The risk-free interest rate assumption is based upon observed interest rates appropriate for the expected life of the stock option awarded. The Company uses historical exercise data to determine the expected lives. Dividend yields have not been a factor in determining fair value of stock options granted as the Company has never issued cash dividends and does not anticipate issuing cash dividends in the future.

Share Repurchase Program

On June 30, 2021, the Company's Board of Directors approved a stock repurchase program (the “Share Repurchase Program”) authorizing the Company to repurchase up to $20.0 million of the Company’s outstanding common stock through June 30, 2024. The Share Repurchase Program will be subject to market conditions, the periodic capital needs of the Company’s operating activities, and the continued satisfaction of all covenants under the Company’s existing 2021 Credit Agreement. Repurchases under the program may take place in the open market or in privately negotiated transactions and may be made under a Rule 10b5-1 plan. The Share Repurchase program does not obligate the Company to repurchase shares and may be suspended, terminated, or modified at any time.

As of December 31, 2022, the Company had repurchased approximately $6.0 million, or 531,347 shares, of the Company's outstanding common stock under the Share Repurchase Program.

14.Business Segment Information

The Company’s reportable segments are organized based on service platforms, with the ITS segment reflecting higher margin rental revenues that generally include payments made by third-party and direct payers and the DME Services segment reflecting lower margin product sales, direct payer rental and services revenues. Resources are allocated and performance is assessed for these segments by the Company’s Chief Executive Officer, whom the Company has determined to be its chief operating decision-maker. The Company believes that reporting performance at the gross profit level is the best indicator of segment performance.

The financial information summarized below is presented by reportable segment:

Item 9A.    Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

Management, with the participation of our Chief Executive Officer (“CEO”) and our Chief Financial Officer (“CFO”), evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2022. The term “disclosure controls and procedures,” as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Based on the evaluation performed as of December 31, 2022, as a result of the material weaknesses in internal control over financial reporting that are described below in Management's Report on Internal Control Over Financial Reporting, our Chief Executive Officer and Chief Financial Officer determined that the Company's disclosure controls and procedures were not effective as of such date.

Inherent Limitations over Internal Controls and Procedures

A company's internal control over financial reporting is a process designed by, or under the supervision of, its principle executive and principal financial officers, and effected by such company's board of directors, management and other personnel to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles ("US GAAP") and includes those policies and procedures that:

•pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;

•provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with US GAAP, and that the receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and

•provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving their objectives. Further, the design of a control system must reflect that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements or fraud. Also, projections of any evaluation of effectiveness of controls in future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management’s Report on Internal Controls Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Exchange Act Rule 13a-15(f) and 15d-15(f). Management, with the participation of our Chief Executive Officer and Chief Financial Officer, has conducted an evaluation of the effectiveness of the Company's internal control over financial reporting as of December 31, 2022, based on the framework set forth in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO).

Based on this assessment, management has concluded that the Company did not maintain effective internal control over financial reporting as of December 31, 2022 due to the material weaknesses described below. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable

70

possibility that a material misstatement of a company's annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

Material Weaknesses in Internal Control Over Financial Reporting

Management has determined that the Company had the following material weaknesses in its internal control over financial reporting:

•The Company did not design and implement effective controls over the completeness and accuracy of information produced by the entity ("IPE") and used by control owners in the operation of certain controls across the financial statement areas.

•The Company did not design and implement effective controls in the financial reporting processes, including general information technology controls over access rights within certain financial reporting and accounting applications, which led to ineffective segregation of duties over the creation and review of journal entries and account reconciliations, including batch journal entries.

•The Company did not design and implement effective controls over management’s review of established pricing and contract terms to support recorded revenue and accounts receivable for the DME Services Direct Payer Rentals, DME Services Product Sales, DME Services - Service and ITS Direct Payer Rentals.

Although these material weaknesses did not result in any material misstatement of our consolidated financial statements for the periods presented, and there were no changes to previously released financial results, they could lead to a material misstatement of account balances or disclosures.

Remediation Efforts

The Company has begun the process of, and is focused on, designing and implementing effective internal control measures to improve its internal control over financial reporting and remediate the material weaknesses identified above. The Company's internal control remediation efforts include the following:

•The Company is in the process of designing and implementing controls that address the completeness and accuracy of underlying data used in the performance of controls over accounting transactions.

•The Company is in the process of reassessing and formalizing the design of certain policies relating to access rights and segregating key functions within its financial and information technology applications supporting its internal controls over financial reporting.

•The Company is enhancing policies and procedures to generate documentation sufficient to support customer orders, pricing determinations, and implementing controls to evidence approved pricing and quantities to contractual revenue amounts.

The Company expects that the actions described above and resulting improvements in controls will strengthen its internal control over financial reporting and will address the identified material weaknesses.

Basis of Presentation and Nature of Operations

Basis of Presentation and Nature of Operations

InfuSystem Holdings, Inc. and its consolidated subsidiaries (the “Company”) are a leading national provider of infusion pumps and related products and services for patients in the home, oncology clinics, ambulatory surgery centers, and other sites of care from seven locations in the United States ("U.S.") and Canada. The Company provides products and services to hospitals, oncology practices and facilities and other alternate site health care providers. Headquartered in Rochester Hills, Michigan, the Company delivers local, field-based customer support, and also operates pump service and repair Centers of Excellence in Michigan, Kansas, California, Massachusetts, Texas and Ontario, Canada. InfuSystem Inc. (“ISI”) and First Biomedical, Inc. ("First Biomedical") are both operating subsidiaries of the Company.

The Company’s core service is to supply electronic ambulatory infusion pumps and associated disposable supply kits to oncology clinics, infusion clinics and hospital outpatient chemotherapy clinics to be utilized in the treatment of a variety of cancers including colorectal cancer, pain management and other disease states. The majority of the Company’s pumps are electronic infusion pumps. Smiths Medical, Inc. and Moog Medical Devices Group each supplied more than 10% of the ambulatory pumps purchased by the Company in 2022. The Company has a supply agreement in place with each of these suppliers. Certain “spot” purchases are made on the open market subject to individual negotiation. The Company also supplies Negative Pressure Wound Therapy (“NPWT”) medical equipment, as well as related disposables and ancillary supplies.

In addition, the Company sells or rents new and pre-owned pole-mounted and ambulatory infusion pumps to, and provides biomedical recertification, maintenance and repair services for oncology practices, as well as other alternate site settings including home care and home infusion providers, skilled nursing and acute care facilities, pain centers and others.

The Company purchases new and pre-owned pole-mounted and ambulatory infusion pumps from a variety of sources on a non-exclusive basis. The Company repairs, refurbishes and provides biomedical certification for the devices as needed. The pumps are then available for sale, rental or to be used within the Company’s ambulatory infusion pump management service.

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the U.S. (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”).

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and all wholly owned organizations. All intercompany transactions and account balances have been eliminated in consolidation.

Segments

The Company operates in two reportable segments, Integrated Therapy Services (“ITS”) and Durable Medical Equipment Services (“DME Services”) based on management's view of its business for purpose of evaluating performance and making operating decisions.

The Company’s approach is to make operational decisions and assess performance based on delivering products and services that together provide solutions to its customer base utilizing a functional management structure. Based upon this business model, the Company’s Chief Executive Officer, whom the Company has determined to be its chief operating decision-maker, reviews segment financial information. See Note 14 for segment disclosures.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements, including the notes thereto. The Company considers critical accounting policies to be those that require more significant judgments and estimates in the preparation of its consolidated financial statements, including the following: revenue recognition, leases, accounts receivable and allowance for doubtful accounts, income taxes, equity compensation valuations, and long-lived asset valuations. Management relies on historical experience and other assumptions believed to be reasonable in making its judgments and estimates. Actual results could differ materially from those estimates.

Business Combinations

The Company accounts for all business combinations using the acquisition method of accounting, which allocates the fair value of the purchase consideration to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions. The Company may utilize third-party valuation specialists to assist the Company in the allocation. For intangible assets, the Company typically uses the income approach to determine their estimated fair values. Key estimates and assumptions in that approach include the amount and timing of projected future cash flow, the discount rate selected to measure the risks inherent in those cash flows and the assessment of the asset's useful life. Initial purchase price allocations are subject to revision within the measurement period, not to exceed one year from the date of acquisition. Acquisition-related expenses and transaction costs associated with business combinations are expensed as incurred.

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company maintains substantially all of its cash and cash equivalents primarily with two financial institutions that are insured with the Federal Deposit Insurance Corporation (“FDIC”). At times throughout the year, cash and cash equivalents balances might exceed FDIC insurance limits. Accounts at banks with an aggregate excess of the amount of outstanding checks over the cash balances are included in accounts payable in current liabilities in the consolidated balance sheet. At December 31, 2022, the Company did not have any cash equivalents.

Accounts Receivable and Allowance for Doubtful Accounts

Amounts billed that have not yet been collected that also meet the conditions for unconditional right to payment are presented as accounts receivable. Accounts receivable related to rental service and delivery of products are reported at their estimated transaction prices, inclusive of adjustments for variable consideration, based on the amounts expected to be collected from payers. The Company writes off accounts receivable once collection efforts have been exhausted and an account is deemed to be uncollectible. An allowance for doubtful accounts is established as a result of an adverse change in the Company’s payers’ ability to pay outstanding billings. The allowance for doubtful accounts was $1.1 million as of both December 31, 2022 and 2021.

Inventories

The Company’s inventories consist of disposable medical supplies, replacement parts and other supplies used in conjunction with medical equipment and are stated at the lower of cost (first-in, first-out basis) or net realizable value. Cost primarily represents the purchase price paid for the items on hand. The Company periodically performs an analysis of slow-moving inventory and records an adjustment to reflect the recoverable amount.

Medical Equipment

Medical Equipment (“Equipment”) consists of equipment that the Company purchases from third-parties and is (1) held for sale or rent, and (2) used in service to generate rental revenue. Equipment, once placed into service, is depreciated using the straight-line method over the estimated useful lives of the equipment which is typically seven years. The Company does not depreciate Equipment held for sale or rent. When Equipment in rental service assets are sold, or otherwise disposed, the cost and related accumulated depreciation are removed from the accounts and a gain or loss is recorded in the current period. The Company periodically performs an analysis to identify potentially missing Equipment and records a reserve equal to the underlying net book value, which was $2.3 million and $1.1 million as of December 31, 2022 and 2021, respectively. This amount approximates the accelerated depreciation the Company would recognize over the remaining useful lives of the assets. During the current period, the Company changed its estimate for missing pumps used by certain therapies by shortening the time estimate of when a pump is considered missing. As a result of this change in estimate, the Company increased the pump reserve as of December 31, 2022 and increased its cost of sales for the twelve months ended December 31, 2022 by $0.4 million. The Company performs a similar analysis of slow-moving Equipment for sale or rent and records a reserve, which was less than $0.1 million as of both December 31, 2022 and 2021.

Presentation of Medical Equipment in the Consolidated Statements

The Company purchases medical equipment directly for sale as well as medical equipment that is purchased for either rental or sale and that is unallocated at the time of purchase (“Unallocated Assets”). Management believes that the predominant source of revenues and cash flows from the Unallocated Assets is from rentals and most equipment purchased is likely to be

rented prior to being sold. The Company concluded that (i) the assets specifically supporting its two primary revenue streams should be separately disclosed on the balance sheet; (ii) the purchase and sale of Unallocated Assets should be classified solely in investing cash flows based on their predominant source while medical equipment purchased specifically for sales activity should be classified in operating cash flows; and (iii) other activities ancillary to the rental process should be consistently classified.

Property and Equipment

Property and equipment is stated at acquired cost and depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to seven years. Externally purchased information technology software and hardware are depreciated over three and five years, respectively. Leasehold improvements are amortized using the straight-line method over the life of the asset or the remaining term of the lease, whichever is shorter. Maintenance and minor repairs are charged to operations as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is recorded in the current period.

Goodwill

Goodwill is tested for impairment annually or more frequently when certain events or circumstances trigger a review. Management has the option to first assess qualitative factors such as current performance and overall economic conditions to determine whether or not it is necessary to perform a quantitative goodwill impairment test. If the Company chooses that option, then the Company would not be required to perform a quantitative goodwill impairment test unless the Company determines that, based on a qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the Company determines that an impairment is more likely than not, or if the Company chooses not to perform a qualitative assessment, the Company will then proceed with the quantitative assessment. Under the quantitative test, if the fair value of a reporting unit exceeds its carrying amount, then goodwill of the reporting unit is considered to not be impaired. If the carrying amount of the reporting unit exceeds its fair value, then an impairment loss is recognized in an amount equal to the excess, up to the value of the goodwill. The Company performed its annual impairment analysis by using a quantitative assessment as of October 31, 2022 and determined that there was no impairment.

Intangible Assets

Intangible assets consist of trade names, physician and customer relationships, unpatented technology, non-competition agreements and software. The Company amortizes the value assigned to the physician and customer relationships on a straight-line basis over the period of expected benefit, which ranges from fifteen to twenty years. The acquired physician and customer relationship base represents a valuable asset of the Company due to the expectation of future business opportunities to be leveraged from the existing relationship with each physician and customer. The Company has long-standing relationships with numerous oncology clinics, physicians, home care and home infusion providers, skilled nursing and acute care facilities, pain centers and others. The useful lives of these relationships are based on the expected attrition rates. Acquired software is amortized on a straight-line basis over the period of expected benefit, which ranges from three to five years. Acquired unpatented technology arose from recent acquisitions and is amortized on a straight-line basis over the period of expected benefit, which is seven years. This asset represents acquired knowledge of repair solutions that will be leveraged into opportunities into the acute care market. The non-competition agreements arose from recent acquisitions and are amortized on a straight-line basis over the terms of the agreements, which is five years. Trade names associated with the original acquisition of InfuSystem are not amortized.

Management tests indefinite life trade names for impairment annually or more frequently if deemed necessary. Management has the option of first performing the impairment test for intangible assets with indefinite lives on a qualitative basis, by evaluating factors to determine whether it is more likely than not that an impairment exists. If it is more likely than not that an impairment exists, or if the Company chooses not to perform a qualitative assessment, then a quantitative impairment test is performed. Impairment exists when the carrying amount of the intangible asset exceeds its fair value. If the carrying value of the intangible assets exceeds the fair value, an impairment loss is recognized in an amount equal to that excess. The Company performed its annual impairment analysis by using a quantitative assessment as of October 31, 2022 and determined that the fair value of the trade names with indefinite lives was greater than their carrying value, resulting in no impairment.

Software Capitalization and Depreciation

The Company capitalizes certain costs incurred in connection with obtaining or developing internal-use software, including payroll and payroll-related costs for employees who are directly associated with the internal-use software project, external direct costs of materials and services and interest costs while developing the software. Capitalized software costs are included in intangible assets, net and are amortized using the straight-line method over the estimated useful life of three to five

years. Capitalization of such costs ceases when the project is substantially complete and ready for its intended purpose. Costs incurred during the preliminary project and post-implementation stages, as well as software maintenance and training costs, are expensed in the period in which they are incurred. The Company did not capitalize any internal-use software for the year ended December 31, 2022, but did obtain and capitalize $0.3 million of internal-use software for the year ended December 31, 2021 in connection with the Company's acquisition of OB Healthcare Corporation. Amortization expense for capitalized software was $0.1 million in 2022, $1.6 million in 2021 and $1.9 million in 2020.

The Company assesses impairment indicators related to its internally-developed, internal-use software, specifically looking at the effectiveness and useful lives of each project and sub-project to determine if impairment indicators are present. For the year ended December 31, 2022, the Company assessed the impairment indicators and found none to be present.

Impairment of Long-Lived Assets

Long-lived assets held for use, which includes medical equipment in rental service, property and equipment and amortizable intangible assets, are reviewed for impairment when events or changes in circumstances indicate that their carrying value may not be recoverable. If an impairment indicator exists, the Company assesses the asset or asset group for recoverability. Recoverability of these assets is determined based upon the expected undiscounted future net cash flows from the operations to which the assets relate, utilizing management’s best estimates, appropriate assumptions and projections at the time. If the carrying value is determined not to be recoverable from future operating cash flows, the asset is deemed impaired and an impairment loss would be recognized to the extent the carrying value exceeded the estimated fair market value of the asset or asset group. For the years ended December 31, 2022, 2021 and 2020, respectively, the Company assessed the impairment indicators and found none to be present.

Leases

The Company accounts for leases following Accounting Standards Codification ("ASC") Topic 842, Leases,("Topic 842"). Under Topic 842, lessees are required to recognize a lease liability and right-of-use asset (“ROU asset”) for all leases and to disclose key information about leasing arrangements. Additionally, leases are classified as either financing or operating; the classification determines the pattern of expense recognition and classification within the statement of operations. The Company elected to apply its lease accounting policy only to leases with a term greater than twelve months.

Topic 842 provides practical expedients for an entity’s ongoing accounting. The Company elected the “combining lease and non-lease components” practical expedient and also elected to apply the short-term lease recognition exemption to certain leases; therefore, the Company did not recognize ROU assets and lease liabilities for these leases.

In adopting Topic 842, the Company determined and will continue to determine whether an arrangement is a lease at inception. The Company’s operating leases are primarily for office space, service facility centers and equipment under operating lease arrangements that expire at various dates over the next nine years. The Company’s leases do not contain any restrictive covenants. The Company’s office leases generally contain renewal options for periods ranging from one to five years. Because the Company is not reasonably certain to exercise these renewal options, the options are not considered in determining the lease term, and payments associated with the option years are excluded from lease payments. The Company’s office leases do not contain any material residual value guarantees. The Company’s equipment leases generally do not contain renewal options. The Company is not reasonably certain to exercise the renewal options for those equipment leases that do contain renewal options, thus, the options are not considered in determining the lease term and payments associated with the option years are excluded from lease payments.

For the Company’s equipment leases, the Company used and will use the implicit rate in the lease as the discount rate, when available. Otherwise, the Company uses its incremental borrowing rate as the discount rate. For the Company’s office leases, the implicit rate is typically not available, so the Company used and will use its incremental borrowing rate as the discount rate. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments. The Company’s lease agreements include both lease and non-lease components.

Payments due under the Company’s operating leases include fixed payments as well as variable payments. For the Company’s office leases, variable payments include amounts for the Company’s proportionate share of operating expenses, utilities, property taxes, insurance, common area maintenance and other facility-related expenses. For the Company’s equipment leases, variable payments may consist of sales taxes, property taxes and other fees.

Revenue Recognition

Revenue is recognized at the time and in an amount that reflects the consideration expected to be received for the performance obligations that have been provided. ASC Topic 606 – Revenue from Contracts with Customers (“ASC 606”) defines contracts as written, oral and through customary business practice. Under this definition, the Company considers contracts to be created at the time that the rental service is authorized or an order to purchase product is agreed upon regardless of whether or not there is a written contract.

The Company has three separate and distinct performance obligations offered to its customers: a rental service performance obligation, a product sale performance obligation and a service performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account for revenue recognition under ASC 606. These performance obligations are related to separate revenue streams and at no point are they combined into a single transaction. Sources of net revenues include commercial insurance payers, government insurance payers, medical facilities and patients.

The Company generates its revenues from the rental of infusion pumps to its customers and from product sales and services. For the rental service performance obligation, revenue is based on its standalone price, determined by using reimbursement rates established by third-party payer or other contracts. Revenue is recognized in the period in which the related performance obligation is satisfied, which is typically at the point in time that a patient concludes a treatment, or in certain arrangements, based on the number of pumps that a facility has onsite. The Company’s revenues related to product sales are recognized at the time that control of the product has been transferred to the customer; either at the time the product is shipped or the time the product has been received by the customer, depending on the delivery terms. The Company does not commit to long-term contracts to sell customers a certain minimum quantity of products. The Company's revenues related to services are recognized at the time that the service work has been completed.

The Company employs certain significant judgments to estimate the dollar amount of revenue, and related concessions, allocated to the rental service. These judgments include, among others, the estimation of variable consideration. Variable consideration, specifically related to the Company’s third-party payer rental revenues, is estimated as implied price concessions resulting from differences between the rates charged for services performed and the expected reimbursements for commercial payers and other implied customer concessions. The estimates for variable consideration are based on historical collections with similar payers, aged accounts receivable by payer class and payer correspondence using the portfolio approach, which provide a reasonable basis for estimating the variable portion of a transaction. The Company doesn’t believe it is probable that a significant reversal of revenue will occur in future periods because (i) there is no significant uncertainty about the amount of considerations that are expected to be collected based on collection history and (ii) the large number of sufficiently similar contracts allows the Company to adequately estimate the component of variable consideration.

Net revenues are adjusted when changes in estimates of variable consideration occur. Changes in estimates typically arise as a result of new information obtained, such as actual payment receipt or denial, or pricing adjustments by payers. Subsequent changes to estimates of transaction prices are recorded as adjustments to net revenue in the period of the change. Subsequent changes that are determined to be the result of an adverse change in the payer’s ability to pay are recorded as an allowance for doubtful accounts.

Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenues and accounts receivable at their net realizable values. Inherent in these estimates is the risk that the estimates will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payers may result in adjustments to amounts originally recorded. Due to continuing changes in the health care industry and third-party reimbursement, it is possible that management’s estimates could change in the near term, which could have a material impact on the Company’s results of operations and cash flows.

Cost of Revenues

Cost of revenues include the costs of servicing and maintaining pumps, products and services sold, shipping and other direct and indirect costs related to net revenues. Shipping and handling costs incurred after control over a product has transferred to a customer are accounted for as a fulfillment cost.

Customer Concentration

As of December 31, 2022, the Company had contracts with nearly 800 third-party payer networks, an increase of 4% over the prior year period. Material terms of contracts with third-party payer organizations are typically a pre-negotiated fee

schedule rate or a then-current proprietary fee schedule rate for equipment and supplies provided. The majority of these contracts generally provide for a term of one year, with automatic one-year renewals, unless the Company or the contracted payer elect not to renew. The Company also contracts with various other third-party payer organizations, Medicaid, commercial Medicare replacement plans, self-insured plans, facilities of its Medicare patients and numerous other insurance carriers. No single payer or customer represented more than 10% of the Company's net revenue in 2022, 2021 or 2020.

Income Taxes

The Company recognizes deferred income tax liabilities and assets based on (i) the differences between the financial statement carrying amounts and the tax basis of assets and liabilities, using enacted tax rates in effect in the years the differences are expected to reverse and (ii) the tax credit carryforwards. Deferred income tax (expense) benefit results from the change in net deferred tax assets or deferred tax liabilities. A valuation allowance is recorded when it is more likely than not that some or all of any deferred tax assets will not be realized.

Provisions for federal, state and foreign taxes are calculated based on reported pre-tax earnings based on current tax law and include the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Certain items of income and expense are recognized in different time periods for financial reporting than for income tax purposes; thus, such provisions differ from the amounts currently receivable or payable.

The Company follows a two-step approach for recognizing uncertain tax positions. First, it evaluates the tax position for recognition by determining if the weight of available evidence indicates it is more-likely-than-not that the position will be sustained upon examination. Second, for positions that are determined are more-likely-than-not to be sustained, it recognizes the tax benefits as the largest benefit that has a greater than 50% likelihood of being sustained. The Company establishes a reserve for uncertain tax positions liability that is comprised of unrecognized tax benefits and related interest and penalties. The Company adjusts this liability in the period in which an uncertain tax position is effectively settled, the statute of limitations expires for the relevant taxing authority to examine the tax position, or more information becomes available.

The Company adopted Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, in the fourth quarter of 2019. This guidance simplifies various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The guidance was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption was permitted, including adoption in any interim period for which financial statements had not yet been issued. Certain amendments may have been applied on a retrospective, modified retrospective or prospective basis. As permitted, the Company elected to early adopt this guidance for the year ended December 31, 2019. The adoption of this guidance did not have a significant impact on the Company’s financial statements and primarily resulted in the reclassification of an immaterial amount from non-income tax expense to income tax expense related to the accounting for franchise taxes, with no impact to the Company’s consolidated net income, equity or cash flows.

Treasury Stock

The Company periodically repurchases shares of its common stock. These repurchases take place either as part of a board-authorized program, which may include open market transactions or privately negotiated transactions and may be made under a Rule 10b5-1 plan, or in targeted stock purchase agreements approved by the board. Treasury stock is accounted for using the par value method. In 2021, the Company retired the approximately 3,500,000 shares that were previously held in treasury. As of December 31, 2022, the Company does not have any shares being held in treasury.

Share-Based Payments

The Company determines the fair value of stock option awards, restricted stock awards and stock appreciation rights (collectively, “Share-Based Awards”) on the date of grant using either the grant date price of the Company's common stock or option-pricing models which are affected by the Company’s stock price, as well as assumptions regarding a number of other inputs using the Black-Scholes pricing model. These variables include the Company’s expected stock price volatility over the expected term of the Share-Based Awards, actual and projected employee stock option exercise behaviors, risk-free interest rates and expected dividends. The expected volatility is based on the historical volatility. The expected term represents the period over which the Share-Based Awards are expected to be outstanding. The dividend yield is an estimate of the expected dividend yield on the Company’s stock. The risk-free rate is based on U.S. Treasury yields in effect at the time of the grant for the expected term of the Share-Based Awards. Forfeitures are recognized as they occur. All Share-Based Awards are amortized based on their graded vesting over the requisite service period of the awards. Compensation costs are recognized over the requisite service period using the accelerated method and included in general and administrative expenses.

Additionally, the Company also determines the fair value of performance-based restricted stock units (“PSUs”) based upon the type of performance measure. These awards typically vest after the Company’s achievement of either a specific Company performance metric or when the market value of the Company’s stock meets a specific metric such as when the closing price of the Company's stock reaches a target value for a minimum number of consecutive trading days. Under Financial Accounting Standards Board (“FASB”) ASC Topic 718, the provisions of the PSUs that vest upon achievement of a target market value are considered a market condition, and therefore the effect of that market condition is reflected in the grant date fair value for this type of award. A third-party valuation expert was engaged to prepare a “Monte Carlo simulation” to account for the market condition to assist management in its conclusion of fair value. That simulation takes into account the beginning stock price of the Company’s common stock, the expected volatilities for the Company’s stock price and the expected risk-free rate of return. The single grant-date fair value computed by this valuation method is recognized by the Company in accounting for the awards regardless of the actual future outcome of the market condition. Compensation costs are accelerated if the market condition is satisfied prior to the end of the service period derived under the Monte Carlo simulation. The grant date fair value of the other PSUs is calculated as the closing price of the Company’s common stock on the grant date multiplied by the number of shares estimated to be delivered subject to the award terms. Company performance measure goals are considered a performance condition and the timing and amount of compensation cost for those PSUs corresponds with management’s expectation of the probable outcome of the performance conditions as of the grant date and during the vesting period.

Deferred Debt Issuance Costs

Capitalized debt issuance costs as of December 31, 2022 and 2021 relate to the Company’s credit facility. The costs related to the agreement are netted against current and non-current debt. The Company amortizes these costs using the interest method through the maturity date of the underlying debt.

Earnings Per Share

The Company reports its earnings per share which includes the presentation of both basic and diluted earnings per share on the statements of operations. The diluted weighted average common shares include adjustments for the potential effects of outstanding stock options but only in the periods in which such effect is dilutive under the treasury stock method. Included in our basic and diluted weighted average common shares are those stock options and restricted stock awards due to participants granted from the 2014 and 2021 stock incentive plans. Anti-dilutive stock awards are comprised of stock options and unvested restricted stock awards, which would have been anti-dilutive in the application of the treasury stock method. In periods where the Company records a net loss, the diluted per share amount is the same as the basic per share amount.

In accordance with this topic, the following table reconciles income and share amounts utilized to calculate basic and diluted net income per common share:

	Years Ended December 31,
	2022		2021		2020
Numerator (in thousands):
Net income:	$	18	$	1,420	$	17,332
Denominator:
Weighted average common shares outstanding:
Basic	20,648,818		20,519,958		20,106,940
Dilutive effect of common stock equivalents	898,488		1,529,701		1,610,276
Diluted	21,547,306		22,049,659		21,717,216

Stock options of 1,085,855, 368,056 and 18,321 shares were not included in the calculation for the years ended December 31, 2022, 2021 and 2020, respectively, because they would have an anti-dilutive effect.

Derivatives

The Company recognizes all derivative financial instruments as cash flow hedges which are shown as either assets or liabilities on the Company’s consolidated balance sheets at fair value. For derivative contracts which can be classified as a cash flow hedge, the effective portion of the change in fair value of the derivative is recorded to accumulated other comprehensive income (“AOCI”) in the consolidated balance sheets. The underlying hedge transaction is realized when the interest payments

on debt are accrued; the applicable amount of gain or loss included in AOCI is reclassified into earnings in the consolidated statements of operations on the same line as the gain or loss on the hedged item attributable to the hedged risk. The cash flows from derivatives are classified as operating activities.

The Company maintains a policy of requiring that all derivative instruments be governed by an International Swaps and Derivatives Association Master Agreement and settles on a net basis.

The fair values of the Company’s derivative financial instruments are categorized as Level 2 of the fair value hierarchy as the values are derived using the market approach based on observable market inputs including quoted prices of similar instruments and interest rate forward curves.

Fair Value of Financial Instruments

The carrying amounts reported in the consolidated balance sheets as of December 31, 2022 and 2021 for cash, accounts receivable, accounts payable and other current liabilities approximate fair value because of the short-term nature of these instruments (Level I). The carrying value of the Company’s long-term debt with variable interest rates approximates fair value based on instruments with similar terms (Level II).

The Company has adopted ASC 820, Fair Value Measurements, which defines fair value, establishes a framework for assets and liabilities being measured and reported at fair value and appends disclosures about fair value measurements.

For financial assets and liabilities measured at fair value on a recurring basis, fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value as follows:

Level I:    quoted prices in active markets for identical instruments;

Level II:    quoted prices in active markets for similar instruments, quoted prices for identical instruments in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the instrument; and

Level III:    significant inputs to the valuation model are unobservable.

Recent Accounting Pronouncements and Developments

The Company has adopted ASU 2020-04, Reference Rate Reform (Topic 848), which contains optional expedients for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Inter-bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848): Scope." This ASU clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The Company has elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments (Topic 326) Credit Losses”. Topic 326 changes the impairment model for most financial assets and certain other instruments. Under the new standard, entities holding financial assets and net investment in leases that are not accounted for at fair value through net income are to be presented at the net amount expected to be collected. An allowance for credit losses will be a valuation account that will be deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. Topic 326 was originally effective as of January 1, 2020, although in November 2019, the FASB delayed the effective date until fiscal years beginning after December 15, 2022 for SEC filers eligible as of the FASB's deferral date to be smaller reporting companies under the SEC’s definition. The Company qualified as a smaller reporting company in November 2019 when the FASB delayed the effective date of Topic 326. Early adoption is permitted. The Company is currently evaluating the impact of Topic 326 on its consolidated balance sheets, statements of operations, statements of cash flows and related disclosures.

Business Combinations

Acquisitions Accounted for Using the Purchase Method

On January 31, 2021, the Company acquired the business and the majority of the assets of FilAMed, a privately-held biomedical services company based in Bakersfield, California. In becoming a part of the Company's DME Services segment, this acquisition supplemented the Company’s existing biomedical recertification, maintenance and repair services for acute care facilities and other alternate site settings including home care and home infusion providers, skilled nursing facilities, pain centers and others.

On April 18, 2021, the Company acquired the business and substantially all of the assets of OB Healthcare Corporation (“OB Healthcare”), a privately-held biomedical services company based in Austin, Texas. OB Healthcare specializes in on-site repair, preventative maintenance, and device physical inventory management to hospitals and healthcare systems nationwide. The acquisition further develops and expands InfuSystem’s DME Services segment and complements the Company’s purchase of FilAMed.

The results of operations for FilAMed and OB Healthcare are included in the Company’s consolidated statements of operations from the respective closing dates.

Purchase Price Allocation

Pursuant to ASC Topic 805, “Business Combinations,” the purchase price for each of the acquisitions was allocated to the assets acquired and liabilities assumed based upon their estimated fair values as of the respective acquisition dates. The purchase price allocations were primarily based upon a valuation using management’s estimates and assumptions. The purchase price allocation was completed for FilAMed and OB Healthcare as of December 31, 2021. The following tables summarize the consideration paid and the allocation of the purchase price to the fair values of the assets acquired and liabilities assumed as of the respective acquisition dates for both FilAMed and OB Healthcare (in thousands):

	FilAMed		OB Healthcare		Total Consideration
Cash	$	1,400	$	6,250	$	7,650

Operating lease liabilities	(281)		(7)		(288)
Total - purchase price	$	1,400	$	7,325	$	8,725

The amount of acquisition costs for both transactions was $0.2 million and is included in general and administrative expenses for the year ended December 31, 2021.

The Company fully paid all consideration for FilAMed as of December 31, 2021. On the OB Healthcare acquisition date, the Company made an initial cash payment of $6.1 million with subsequent cash payments of $0.4 million during the year ended December 31, 2021 and had an additional estimated amount due to the seller for contingent consideration of $0.8 million,

which was recorded in the balance sheet under the heading for other current liabilities. The contingent consideration arrangement, as amended, required the Company to pay OB Healthcare $0.8 million if certain written contracts were executed. As of December 31, 2022, the requirement under the contingent consideration arrangement had been satisfied and the Company made the required payment.

The following table shows the breakdown of the identified intangible assets acquired into major intangible asset classes for both acquisitions:

	Acquisition Date Fair Value (Thousands)		Weighted-Average Amortization Period (Years)
Customer relationships	$	2,300	15
Unpatented technology	943		7
Non-competition agreements	472		5
Internal-use software	300		5
Total intangible assets (a)	$	4,015	11.2
(a) There was no residual value, renewal terms or extensions associated with any intangible assets acquired.

The goodwill acquired consists of expected synergies from combining operations of FilAMed and OB Healthcare with the DME Services segment as well as their respective assembled workforce who have specialized knowledge and experience. All of the goodwill is deductible for tax purposes.

Unaudited Pro Forma Financial Information

The pump reserve for medical equipment in rental service represents an estimate for medical equipment that is considered to be missing. The reserve calculated is equal to the net book value of assets that have not returned from the field within a certain timeframe. During the current period, the Company changed its estimate for missing pumps used by certain therapies by shortening the time estimate of when a pump is considered missing. As a result of this change in estimate, the Company increased the pump reserve as of December 31, 2022 and increased its cost of sales for the twelve months ended December 31, 2022 by $0.4 million.

Debt

Debt

On February 5, 2021, the Company entered into a Credit Agreement (the “2021 Credit Agreement”) with JPMorgan Chase Bank, N.A., as administrative agent (the “Agent”), sole bookrunner and sole lead arranger, and the lenders party thereto. The borrowers under the 2021 Credit Agreement are the Company, InfuSystem Holdings USA, Inc. (“Holdings”), ISI, First Biomedical, and IFC LLC (“IFC” and, collectively with the Company, Holdings, ISI and First Biomedical, the “Borrowers”).

The 2021 Credit Agreement provides for a revolving credit facility (the “Revolving Facility”) of $75.0 million, maturing on February 5, 2026. The Revolving Facility may be increased by $25.0 million, subject to certain conditions, including the consent of the Agent and obtaining necessary commitments. The lenders under the 2021 Credit Agreement may issue up to $7.0 million in letters of credit subject to the satisfaction of certain conditions. On February 5, 2021, the Borrowers made an initial borrowing of $30.0 million under the Revolving Facility. Proceeds from the loan, along with approximately $8.2 million in cash, were used to repay all amounts due under the Company’s then existing credit facility dated March 23, 2015 (the “2015 Credit Agreement”).

The 2021 Credit Agreement has customary representations and warranties. The ability to borrow under the facility is subject to ongoing compliance with a number of customary affirmative and negative covenants, including limitations on indebtedness, liens, mergers, acquisitions, investments, asset sales, affiliate transactions and restricted payments, as well as financial covenants, including the following:

•a minimum fixed charge coverage ratio (defined as the ratio of consolidated EBITDA (as defined in the 2021 Credit Agreement) less 50% of depreciation expense), to consolidated fixed charges (as defined in the 2021 Credit Agreement)) for the prior four most recently ended calendar quarters of 1.20 to 1.00; and

•a maximum leverage ratio (defined as total indebtedness to EBITDA for the prior four most recently ended calendar quarters) of 3.50 to 1.00.

The 2021 Credit Agreement includes customary events of default. The occurrence of an event of default will permit the lenders to terminate commitments to lend under the Revolving Facility and accelerate payment of all amounts outstanding thereunder.

Simultaneous with the execution of the 2021 Credit Agreement, the Company entered into a Pledge and Security Agreement to secure repayment of the obligations of the Borrowers. Under the Pledge and Security Agreement, each Borrower has granted to the Agent, for the benefit of various secured parties, a first priority security interest in substantially all of the personal property assets of each of the Borrowers, including the shares of each of Holdings, ISI and First Biomedical and the equity interests of IFC.

On February 5, 2021, in connection with the execution and closing of the 2021 Credit Agreement, the Company, along with its wholly owned subsidiaries as borrowers, terminated the 2015 Credit Agreement. All outstanding loans under the 2015 Credit Agreement have been repaid and all liens under the 2015 Credit Agreement have been released, except that a letter of credit originally issued under the 2015 Credit Agreement in the amount of approximately $0.8 million was transferred to the 2021 Credit Agreement.

The 2021 Credit Agreement was accounted for as a debt modification that resulted in a small increase to deferred debt issuance costs. As of December 31, 2022, the Company was in compliance with all debt-related covenants under the 2021 Credit Agreement.

On April 15, 2019, the Company sold for $2.0 million and immediately leased back certain medical equipment in rental service to a third party specializing in such transactions. The leaseback term was 36 months. Because the arrangement contains a purchase option that the Company is reasonably certain to exercise, this transaction did not qualify for the sale-leaseback accounting under ASC 842. The medical equipment remains recorded on the accompanying condensed consolidated balance sheet and the proceeds received have been classified as an other financing liability. During the fourth quarter of 2021, the Company recorded an additional $0.2 million of interest expense to reflect the amount expected to be paid upon the exercise of the purchase option at the end of its other financing transaction. As of December 31, 2022, all amounts owed under this arrangement had been paid.

As of December 31, 2022, amounts outstanding under the Revolving Facility provided under the 2021 Credit Agreement bear interest at a variable rate equal to, at the Company’s election, a LIBO Rate for Eurodollar loans or an Alternative Base Rate for ABR loans, as defined by the 2021 Credit Agreement, plus a spread that will vary depending upon the Company’s leverage ratio. The spread ranges from 2.00% to 3.00% for Eurodollar Loans and 1.00% to 2.00% for base rate loans. The weighted-average Eurodollar loan rate at December 31, 2022 was 6.52% (LIBO of 4.27% plus 2.25%). The actual ABR loan rate at December 31, 2022 was 8.75% (lender’s prime rate of 7.50% plus 1.25%).

Derivative Financial Instruments and Hedging Activities

Derivative Financial Instruments and Hedging Activities

In February 2021, the Company adopted a derivative investment policy which provides guidelines and objectives related to managing financial and operational exposures arising from market changes in short term interest rates. In accordance with this policy, the Company can enter into interest rate swaps or similar instruments, will endeavor to evaluate all the risks inherent in a transaction before entering into a derivative financial instrument and will not enter into derivative financial instruments for speculative or trading purposes. Hedging relationships are formally documented at the inception of the hedge and hedges must be highly effective in offsetting changes to future cash flows on hedged transactions at the inception of a hedge and on an ongoing basis to be designated for hedge accounting treatment.

The Company is exposed to interest rate risk related to its variable rate debt obligations under the 2021 Credit Agreement. In order to manage the volatility in interest rate markets, in February 2021, the Company entered into two interest rate swap agreements to manage exposure arising from this risk. On a combined basis, the agreements have a constant notional amount over a 5-year term that ends on February 5, 2026. The agreements both pay the Company 30-day LIBOR on the notional amount and the Company pays a fixed rate of interest equal to 0.73%. These derivative instruments are considered cash flow hedges. The Company does not have any other derivative financial instruments.

The table below presents the location and gross fair value amounts of the Company's derivative financial instruments and the associated notional amounts designated as cash flow hedges (in thousands):

(a) At December 31, 2022 and 2021, this includes state and local net operating losses of $1.2 million and $1.3 million, respectively.

The Company’s U.S. federal net operating loss carryforward for tax purposes was $35.7 million at December 31, 2022, resulting in a federal deferred tax asset of $7.5 million. Approximately $29.1 million of the Company’s U.S. federal net operating loss carryforwards will begin to expire in various years beginning in 2031. $6.6 million of U.S. federal net operating loss carryforwards have an indefinite life. The Company’s state net operating loss carryforward of approximately $1.2 million is comprised of various jurisdictions. These state net operating losses can be used for a period of 5 to 20 years and vary by state, and if unused, begin to expire in 2023, though a substantial portion expires beyond 2023. Approximately $0.1 million of the state net operating loss carryforwards have an indefinite life. Tax benefits of operating loss and tax credit carryforwards are

evaluated on an ongoing basis, including a review of historical and projected future operating results, the eligible carryforward period, and other circumstances.

The Company continues to monitor shifts in past ownership (as defined under Section 382 of the Code).

In the fourth quarter of 2020, it was determined that the valuation allowance against the U.S. federal and state deferred taxes was no longer required and the valuation allowance of $11.2 million that existed was released. The Company’s realization of its deferred tax assets is dependent upon many factors, including, but not limited to, the Company’s ability to generate sufficient taxable income. Management assesses the available positive and negative evidence to estimate if sufficient future taxable income will be generated to use the existing deferred tax assets. At December 31, 2022 and 2021, cumulative income in recent years and projected future taxable income is the basis for the Company’s assessment that the deferred tax assets do not require a valuation allowance.

The Company had no uncertain tax positions for the years ended December 31, 2022 and 2021.

The Company is subject to taxation for Federal and various state jurisdictions in the U.S. and Canada. The Federal income tax returns of the Company for the years 2019 through 2022 are open to examination by the Internal Revenue Service. The Company was under audit with the Internal Revenue Service in relation to the Company’s 2018 federal income tax return and the audit was closed on December 15, 2021. The state income tax returns and other state tax filings of the Company are subject to examination by the state taxing authorities, for various periods generally up to four years after they are filed. Canadian income tax returns of the Company for the years 2018 through 2022 are subject to examination by the Canada Revenue Agency.

On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security ("CARES") Act was enacted in response to the COVID-19 pandemic. The CARES Act among other things, allows employers to defer the deposit and payment of the employer's share of Social Security taxes. The Company, under the CARES Act, deferred paying $0.7 million of applicable gross payroll taxes as of December 31, 2020, which was included in other liabilities. The $0.7 million balance of the deferred Social Security taxes was paid in two annual installments during the years ending December 31, 2021 and 2022, respectively. On April 15, 2020, the Company received a $4.1 million loan under the Federal Paycheck Protection Program (“PPP”) created under the CARES Act. In response to revised eligibility guidelines announced by the U.S. Small Business Administration shortly thereafter, the Company repaid this loan in full on May 7, 2020.

Commitments and Contingencies

Commitments and Contingencies

From time to time in the ordinary course of its business, the Company may be involved in legal and regulatory proceedings, the outcomes of which may not be determinable. The results of litigation and regulatory proceedings are inherently unpredictable. Any claims against the Company, whether meritorious or not, could be time consuming, result in costly litigation, require significant amounts of management time and result in diversion of significant resources. The Company is not able to estimate an aggregate amount or range of reasonably possible losses for those legal matters for which losses are not probable and estimable, primarily for the following reasons: (i) many of the relevant legal proceedings are in preliminary stages, and until such proceedings develop further, there is often uncertainty regarding the relevant facts and circumstances at issue and potential liability; and (ii) many of these proceedings involve matters of which the outcomes are inherently difficult to predict. The Company has insurance policies covering potential losses where such coverage is cost effective.

The Company is not at this time involved in any proceedings that the Company currently believes could have a material effect on the Company’s financial condition, results of operations or cash flows.

Share-Based Compensation

Share-Based Payment Arrangement [Abstract]

Share-Based Compensation

Share-Based Compensation

Stock Incentive Plan

The Company has various stock option and stock-based incentive plans and agreements whereby equity based awards are granted to certain employees, directors and others approved by the Company’s Board of Directors (the “Board”) or Compensation Committee. Grants may be made in the form of stock options, restricted stock awards ("RSUs" or "RSAs"),

performance-based restricted stock units ("PSU's), unrestricted common stock, stock appreciation rights (“SARs”) in addition to other award types. Stock options are granted with an exercise price at, or above, fair market value on the date of grant, generally expire in 5 to 10 years from the grant date and generally become exercisable over a period of up to 3 years. RSUs generally become vested over a period of up to three years. PSUs generally become vested over a period of up to three years based on the performance of a specific achievement. Awards typically vest and are issued only if the participants remain employed by the Company through the vesting date. Common stock issued under these awards are issued from shares reserved under the Company’s plan described below.

On May 18, 2021, the Company’s Board adopted the 2021 Equity Incentive Plan (the “2021 Plan”). The 2021 Plan was approved by the Company’s shareholders at the 2021 Annual Meeting on May 18, 2021 and became effective at that time. The 2021 plan supersedes the 2014 Amended and Restated Stock Incentive Plan (the "2014 Plan"). The 2021 Plan provided for the issuance of a maximum of 2,500,000 shares of common stock in connection with the grant of stock-based or stock-denominated awards. Reductions in the available share limit associated with these grants are based on a fungible ratio of 1:1 for stock options and stock appreciation rights and 2:1 for all other types of awards. Any shares subject to an award that expires or is cancelled, forfeited, or terminated without issuance of the full number of shares of stock to which the award related again become available for issuance under the limit. As of December 31, 2022, a total of 808,799 common shares remained available for future grant under the 2021 Plan. This amount reflects reductions from the original limit for grants reflective of the respective fungible ratios. The available amount also reflects the maximum potential share issuance potential in the case of performance grants that provide for variable share payouts.

On April 23, 2014, the Company’s Board adopted the 2014 Plan. The 2014 Plan was approved by the Company’s shareholders at the 2014 Annual Meeting and became effective as of the date it was adopted by the Board of Directors. The 2014 Plan provided for the issuance of a maximum of 2,000,000 shares of common stock in connection with the grant of stock-based or stock-denominated awards. On July 19, 2018, the Company’s stockholders approved the reservation of an additional 1,000,000 shares to be issued under the 2014 Plan. On May 15, 2019, the Company’s stockholders approved the reservation of an additional 1,000,000 shares to be issued under the 2014 Plan. The 2021 Plan replaces and supersedes the 2014 Plan, so as of the adoption date of the 2021 Plan, no common shares remained available for future grant under the 2014 Plan.

Stock-Based Compensation Expense

All stock option awards are amortized based on their graded vesting over the requisite service period of the awards. Compensation costs are recognized over the requisite service period using the accelerated method and included in general and administrative expenses.

The following table presents the total stock-based compensation expense, which is included in selling, general and administrative expenses (in thousands):

	Years Ended December 31,

Shares Forgone to Satisfy Minimum Statutory Withholdings

During the years ended December 31, 2022, 2021 and 2020, shares of common stock were issued to employees and directors as their restricted stock awards vested or stock options were exercised. Under the terms of the Company’s stock plans, at the election of each employee, the Company can authorize a net settlement of distributable shares to employees in order to satisfy an individual employees' tax withholding obligations. For the years ended December 31, 2022, 2021 and 2020, the Company received 136,718 shares, 57,067 shares and 146,763 shares, respectively, from employees for tax withholding obligations.

Restricted Stock Awards

Restricted stock awards entitle the holder to receive, upon meeting certain time-based vesting criteria, a specified number of shares of the Company’s common stock. Stock-based compensation cost of restricted stock awards is measured by the market value of the Company’s common stock on the date of grant.

The following table summarizes the Company’s restricted share activity, excluding the Company’s employee stock purchase plan:

	Number of shares	Weighted average grant date fair value
Unvested at December 31, 2021	290,942	$	15.61

Total fair value of shares forgone to satisfy minimum statutory withholding	$	172,662	$	32,282	$	62,479

As of December 31, 2022, there was $3.2 million of pre-tax total unrecognized compensation cost related to non-vested restricted stock awards, which will be adjusted for future forfeitures, if any. The Company expects to recognize such cost over a weighted average period of two years

Performance-Based Restricted Stock Units

During the year ended December 31, 2022, the Company granted approximately 53,864 PSUs and during the year ended December 31, 2021, the Company granted approximately 127,476 PSUs. PSUs entitle the holder to receive, upon meeting certain performance-based vesting criteria, a specified number of shares of the Company’s common stock. These awards typically vest after the Company’s achievement of either a Company-based performance metric, such as the achievement of a certain amount of net revenue during a specified period, coupled with a time-based vesting criteria or based on a market based metric of the Company’s stock, such as when the trading price reaches a target value for a minimum number of consecutive trading days. All of the PSUs granted in 2022 and 2021 are earned based on specified Company-based performance measure conditions. In the case of the market-based metric, awards are paid in stock immediately upon achievement of the performance condition or expire without any payment after the third anniversary of the grant date. In the case of the specified Company-based performance measure, awards can be earned at an amount that varies by award between 93% to 100% of the target number of shares for achieving a minimum threshold below the target or up to 200% of the target number of shares for exceeding the target, with a linear adjustment between threshold and target or between target and stretch performance goals.

The following table summarizes the Company’s PSU activity:

As of December 31, 2022, there was no pre-tax total unrecognized compensation cost related to non-vested PSUs, which will be adjusted for changes to management’s expectations of the probable outcomes of the performance conditions, if any.

Employee Stock Purchase Plan

In May 2014, the Company received approval from stockholders to adopt an employee stock purchase plan ("ESPP") effective October 2014 (collectively the “Original ESPP”). Under the Original ESPP, 200,000 shares of common stock were authorized for purchase by eligible employees at a 15% discount through payroll deductions during the six-month offering periods. Shares were purchased in whole numbers and generally would be the last day of the offering period. In September 2016, the Company received approval from shareholders for an additional 350,000 shares. No employee may purchase more than $25,000 worth of fair market value shares in any calendar year. As allowed under the ESPP, a participant may elect to withdraw from the plan, effective for the purchase period in progress at the time of the election with all accumulated payroll deductions returned to the participant at the time of withdrawal. As of December 31, 2022, there were 95,379 shares remaining available for future issuance. The following table summarizes the activity relating to the Company’s ESPP program:

	Years Ended December 31,

Compensation expense	$	229,064	$	173,561	$	108,589
Shares of stock sold to employees	60,673		31,624		30,012
Weighted average fair value per ESPP award	$	11.53	$	16.95	$	7.43

Stock Options

The Company calculates the fair value of stock option awards using the Black-Scholes option pricing model, which incorporates various assumptions including volatility, expected term, risk-free interest rates and dividend yields. The expected volatility assumption is based on historical volatility of the Company’s common stock over the most recent period commensurate with the expected life of the stock option granted. The Company uses historical volatility because management believes such volatility is representative of prospective trends. The risk-free interest rate assumption is based upon observed interest rates appropriate for the expected life of the stock option awarded. The Company uses historical exercise data to determine the expected lives. Dividend yields have not been a factor in determining fair value of stock options granted as the Company has never issued cash dividends and does not anticipate issuing cash dividends in the future.

The following tables detail the various stock option activity:

2014 Plan (Options)	Number of Authorized Shares	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (in Years)	Aggregate Intrinsic Value

Share Repurchase Program

On June 30, 2021, the Company's Board of Directors approved a stock repurchase program (the “Share Repurchase Program”) authorizing the Company to repurchase up to $20.0 million of the Company’s outstanding common stock through June 30, 2024. The Share Repurchase Program will be subject to market conditions, the periodic capital needs of the Company’s operating activities, and the continued satisfaction of all covenants under the Company’s existing 2021 Credit Agreement. Repurchases under the program may take place in the open market or in privately negotiated transactions and may be made under a Rule 10b5-1 plan. The Share Repurchase program does not obligate the Company to repurchase shares and may be suspended, terminated, or modified at any time.

As of December 31, 2022, the Company had repurchased approximately $6.0 million, or 531,347 shares, of the Company's outstanding common stock under the Share Repurchase Program.

Segment Reporting [Abstract]

Business Segment Information

Business Segment Information

The Company’s reportable segments are organized based on service platforms, with the ITS segment reflecting higher margin rental revenues that generally include payments made by third-party and direct payers and the DME Services segment reflecting lower margin product sales, direct payer rental and services revenues. Resources are allocated and performance is assessed for these segments by the Company’s Chief Executive Officer, whom the Company has determined to be its chief operating decision-maker. The Company believes that reporting performance at the gross profit level is the best indicator of segment performance.

The financial information summarized below is presented by reportable segment:

Covid-19 [Abstract]

COVID-19

COVID-19

On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, which spread globally and throughout the United States. With the exception of in-person visits to customer facilities by the Company's sales staff, the Company continued to operate despite stay-at-home orders and other government mandated shutdowns across the United States and Canada under exceptions allowed by those orders for the healthcare industry. 

During 2020, the Company took a number of precautionary and preemptive steps to protect the safety and well-being of its employees while ensuring continuity of service to its clients, including, transitioning employees to a remote work environment, suspending employee travel, canceling participation in industry events and in-person group meetings, promoting social distancing and enhanced cleaning and sanitization efforts across office locations, and implementing protocols to quarantine employees who may have been exposed to COVID-19, or show relevant symptoms. The Company also executed preparedness plans at its facilities to maintain continuity of operations, which provided for flexible work arrangements without any significant disruptions to its business or control processes. The Company's management team is continuing to actively monitor the situation and continuously communicates with employees, customers and vendors. Other specific actions the Company took included purchasing additional inventory of supplies and pumps, as well as purchasing personal protective equipment for employees. While the Company’s business is considered critical, the Company is unable to predict the impact that the COVID-19 pandemic will have on future periods due to numerous uncertainties. While the COVID-19 pandemic has not had any material unfavorable effects to the Company's financial results for the year ended December 31, 2022, the extent of the impact in the future, if any, will depend on future developments, which are highly uncertain, cannot be predicted and could have a material adverse impact on the Company's financial position, operating results and cash flows. A prolonged outbreak could, among other things, strain the Company's business continuity plans, create delays in the Company's growth and strategic initiatives, reduce the Company's sales and marketing activities, limit the Company's access to financing on favorable terms, increase the Company's exposure to potential impairment charges related to long-lived and intangible assets, hinder the Company's ability to support its clients and operate its business effectively, heighten the risk of disruption to the Company's information and reporting systems and internal controls, including those over financial reporting and other risk management systems, or require the Company to incur substantial costs. The Company continues to closely monitor the impact of the COVID-19 pandemic on all aspects of its business and may take further actions as may be required by federal, state or local authorities, or that the Company determines are in the best interests of its employees, customers and partners. As the conditions surrounding the COVID-19 pandemic continue to evolve rapidly, the Company will continue to actively manage its response in collaboration with customers, government officials and stakeholders, and assess any potential impacts to the Company's financial position and operating results, as well as adverse developments in its business.

Summary of Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2022

Accounting Policies [Abstract]

Principles of Consolidation

Principles of Consolidation

The consolidated financial statements include the accounts of the Company and all wholly owned organizations. All intercompany transactions and account balances have been eliminated in consolidation.

Segments

Segments

The Company operates in two reportable segments, Integrated Therapy Services (“ITS”) and Durable Medical Equipment Services (“DME Services”) based on management's view of its business for purpose of evaluating performance and making operating decisions.

The Company’s approach is to make operational decisions and assess performance based on delivering products and services that together provide solutions to its customer base utilizing a functional management structure. Based upon this business model, the Company’s Chief Executive Officer, whom the Company has determined to be its chief operating decision-maker, reviews segment financial information. See Note 14 for segment disclosures.

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates, assumptions and judgments that affect the amounts reported in the financial statements, including the notes thereto. The Company considers critical accounting policies to be those that require more significant judgments and estimates in the preparation of its consolidated financial statements, including the following: revenue recognition, leases, accounts receivable and allowance for doubtful accounts, income taxes, equity compensation valuations, and long-lived asset valuations. Management relies on historical experience and other assumptions believed to be reasonable in making its judgments and estimates. Actual results could differ materially from those estimates.

Business Combinations

Business Combinations

The Company accounts for all business combinations using the acquisition method of accounting, which allocates the fair value of the purchase consideration to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase consideration over the fair values of these identifiable assets and liabilities is recorded as goodwill. When determining the fair values of assets acquired and liabilities assumed, management makes significant estimates and assumptions. The Company may utilize third-party valuation specialists to assist the Company in the allocation. For intangible assets, the Company typically uses the income approach to determine their estimated fair values. Key estimates and assumptions in that approach include the amount and timing of projected future cash flow, the discount rate selected to measure the risks inherent in those cash flows and the assessment of the asset's useful life. Initial purchase price allocations are subject to revision within the measurement period, not to exceed one year from the date of acquisition. Acquisition-related expenses and transaction costs associated with business combinations are expensed as incurred.

Cash and Cash Equivalents

Cash and Cash Equivalents

The Company considers all highly liquid investments with original maturities of three months or less to be cash equivalents. The Company maintains substantially all of its cash and cash equivalents primarily with two financial institutions that are insured with the Federal Deposit Insurance Corporation (“FDIC”). At times throughout the year, cash and cash equivalents balances might exceed FDIC insurance limits. Accounts at banks with an aggregate excess of the amount of outstanding checks over the cash balances are included in accounts payable in current liabilities in the consolidated balance sheet. At December 31, 2022, the Company did not have any cash equivalents.

Accounts Receivable and Allowance for Doubtful Accounts

Accounts Receivable and Allowance for Doubtful Accounts

Amounts billed that have not yet been collected that also meet the conditions for unconditional right to payment are presented as accounts receivable. Accounts receivable related to rental service and delivery of products are reported at their estimated transaction prices, inclusive of adjustments for variable consideration, based on the amounts expected to be collected from payers. The Company writes off accounts receivable once collection efforts have been exhausted and an account is deemed to be uncollectible. An allowance for doubtful accounts is established as a result of an adverse change in the Company’s payers’ ability to pay outstanding billings. The allowance for doubtful accounts was $1.1 million as of both December 31, 2022 and 2021.

Inventories

Inventories

The Company’s inventories consist of disposable medical supplies, replacement parts and other supplies used in conjunction with medical equipment and are stated at the lower of cost (first-in, first-out basis) or net realizable value. Cost primarily represents the purchase price paid for the items on hand. The Company periodically performs an analysis of slow-moving inventory and records an adjustment to reflect the recoverable amount.

Medical Equipment

Medical Equipment

Medical Equipment (“Equipment”) consists of equipment that the Company purchases from third-parties and is (1) held for sale or rent, and (2) used in service to generate rental revenue. Equipment, once placed into service, is depreciated using the straight-line method over the estimated useful lives of the equipment which is typically seven years. The Company does not depreciate Equipment held for sale or rent. When Equipment in rental service assets are sold, or otherwise disposed, the cost and related accumulated depreciation are removed from the accounts and a gain or loss is recorded in the current period. The Company periodically performs an analysis to identify potentially missing Equipment and records a reserve equal to the underlying net book value, which was $2.3 million and $1.1 million as of December 31, 2022 and 2021, respectively. This amount approximates the accelerated depreciation the Company would recognize over the remaining useful lives of the assets. During the current period, the Company changed its estimate for missing pumps used by certain therapies by shortening the time estimate of when a pump is considered missing. As a result of this change in estimate, the Company increased the pump reserve as of December 31, 2022 and increased its cost of sales for the twelve months ended December 31, 2022 by $0.4 million. The Company performs a similar analysis of slow-moving Equipment for sale or rent and records a reserve, which was less than $0.1 million as of both December 31, 2022 and 2021.

Presentation of Medical Equipment in the Consolidated Statements

The Company purchases medical equipment directly for sale as well as medical equipment that is purchased for either rental or sale and that is unallocated at the time of purchase (“Unallocated Assets”). Management believes that the predominant source of revenues and cash flows from the Unallocated Assets is from rentals and most equipment purchased is likely to be

rented prior to being sold. The Company concluded that (i) the assets specifically supporting its two primary revenue streams should be separately disclosed on the balance sheet; (ii) the purchase and sale of Unallocated Assets should be classified solely in investing cash flows based on their predominant source while medical equipment purchased specifically for sales activity should be classified in operating cash flows; and (iii) other activities ancillary to the rental process should be consistently classified.

Property and Equipment

Property and Equipment

Property and equipment is stated at acquired cost and depreciated using the straight-line method over the estimated useful lives of the related assets, ranging from three to seven years. Externally purchased information technology software and hardware are depreciated over three and five years, respectively. Leasehold improvements are amortized using the straight-line method over the life of the asset or the remaining term of the lease, whichever is shorter. Maintenance and minor repairs are charged to operations as incurred. When assets are sold, or otherwise disposed of, the cost and related accumulated depreciation are removed from the accounts and any gain or loss is recorded in the current period.

Goodwill

GoodwillGoodwill is tested for impairment annually or more frequently when certain events or circumstances trigger a review. Management has the option to first assess qualitative factors such as current performance and overall economic conditions to determine whether or not it is necessary to perform a quantitative goodwill impairment test. If the Company chooses that option, then the Company would not be required to perform a quantitative goodwill impairment test unless the Company determines that, based on a qualitative assessment, it is more likely than not that the fair value of a reporting unit is less than its carrying value. If the Company determines that an impairment is more likely than not, or if the Company chooses not to perform a qualitative assessment, the Company will then proceed with the quantitative assessment. Under the quantitative test, if the fair value of a reporting unit exceeds its carrying amount, then goodwill of the reporting unit is considered to not be impaired. If the carrying amount of the reporting unit exceeds its fair value, then an impairment loss is recognized in an amount equal to the excess, up to the value of the goodwill. The Company performed its annual impairment analysis by using a quantitative assessment as of October 31, 2022 and determined that there was no impairment.

Intangible Assets

Intangible Assets

Intangible assets consist of trade names, physician and customer relationships, unpatented technology, non-competition agreements and software. The Company amortizes the value assigned to the physician and customer relationships on a straight-line basis over the period of expected benefit, which ranges from fifteen to twenty years. The acquired physician and customer relationship base represents a valuable asset of the Company due to the expectation of future business opportunities to be leveraged from the existing relationship with each physician and customer. The Company has long-standing relationships with numerous oncology clinics, physicians, home care and home infusion providers, skilled nursing and acute care facilities, pain centers and others. The useful lives of these relationships are based on the expected attrition rates. Acquired software is amortized on a straight-line basis over the period of expected benefit, which ranges from three to five years. Acquired unpatented technology arose from recent acquisitions and is amortized on a straight-line basis over the period of expected benefit, which is seven years. This asset represents acquired knowledge of repair solutions that will be leveraged into opportunities into the acute care market. The non-competition agreements arose from recent acquisitions and are amortized on a straight-line basis over the terms of the agreements, which is five years. Trade names associated with the original acquisition of InfuSystem are not amortized.

Management tests indefinite life trade names for impairment annually or more frequently if deemed necessary. Management has the option of first performing the impairment test for intangible assets with indefinite lives on a qualitative basis, by evaluating factors to determine whether it is more likely than not that an impairment exists. If it is more likely than not that an impairment exists, or if the Company chooses not to perform a qualitative assessment, then a quantitative impairment test is performed. Impairment exists when the carrying amount of the intangible asset exceeds its fair value. If the carrying value of the intangible assets exceeds the fair value, an impairment loss is recognized in an amount equal to that excess. The Company performed its annual impairment analysis by using a quantitative assessment as of October 31, 2022 and determined that the fair value of the trade names with indefinite lives was greater than their carrying value, resulting in no impairment.

Software Capitalization and Depreciation

Software Capitalization and Depreciation

The Company capitalizes certain costs incurred in connection with obtaining or developing internal-use software, including payroll and payroll-related costs for employees who are directly associated with the internal-use software project, external direct costs of materials and services and interest costs while developing the software. Capitalized software costs are included in intangible assets, net and are amortized using the straight-line method over the estimated useful life of three to five

years. Capitalization of such costs ceases when the project is substantially complete and ready for its intended purpose. Costs incurred during the preliminary project and post-implementation stages, as well as software maintenance and training costs, are expensed in the period in which they are incurred. The Company did not capitalize any internal-use software for the year ended December 31, 2022, but did obtain and capitalize $0.3 million of internal-use software for the year ended December 31, 2021 in connection with the Company's acquisition of OB Healthcare Corporation. Amortization expense for capitalized software was $0.1 million in 2022, $1.6 million in 2021 and $1.9 million in 2020.

The Company assesses impairment indicators related to its internally-developed, internal-use software, specifically looking at the effectiveness and useful lives of each project and sub-project to determine if impairment indicators are present. For the year ended December 31, 2022, the Company assessed the impairment indicators and found none to be present.

Impairment of Long-Lived Assets

Impairment of Long-Lived Assets

Long-lived assets held for use, which includes medical equipment in rental service, property and equipment and amortizable intangible assets, are reviewed for impairment when events or changes in circumstances indicate that their carrying value may not be recoverable. If an impairment indicator exists, the Company assesses the asset or asset group for recoverability. Recoverability of these assets is determined based upon the expected undiscounted future net cash flows from the operations to which the assets relate, utilizing management’s best estimates, appropriate assumptions and projections at the time. If the carrying value is determined not to be recoverable from future operating cash flows, the asset is deemed impaired and an impairment loss would be recognized to the extent the carrying value exceeded the estimated fair market value of the asset or asset group. For the years ended December 31, 2022, 2021 and 2020, respectively, the Company assessed the impairment indicators and found none to be present.

Leases

Leases

The Company accounts for leases following Accounting Standards Codification ("ASC") Topic 842, Leases,("Topic 842"). Under Topic 842, lessees are required to recognize a lease liability and right-of-use asset (“ROU asset”) for all leases and to disclose key information about leasing arrangements. Additionally, leases are classified as either financing or operating; the classification determines the pattern of expense recognition and classification within the statement of operations. The Company elected to apply its lease accounting policy only to leases with a term greater than twelve months.

Topic 842 provides practical expedients for an entity’s ongoing accounting. The Company elected the “combining lease and non-lease components” practical expedient and also elected to apply the short-term lease recognition exemption to certain leases; therefore, the Company did not recognize ROU assets and lease liabilities for these leases.

In adopting Topic 842, the Company determined and will continue to determine whether an arrangement is a lease at inception. The Company’s operating leases are primarily for office space, service facility centers and equipment under operating lease arrangements that expire at various dates over the next nine years. The Company’s leases do not contain any restrictive covenants. The Company’s office leases generally contain renewal options for periods ranging from one to five years. Because the Company is not reasonably certain to exercise these renewal options, the options are not considered in determining the lease term, and payments associated with the option years are excluded from lease payments. The Company’s office leases do not contain any material residual value guarantees. The Company’s equipment leases generally do not contain renewal options. The Company is not reasonably certain to exercise the renewal options for those equipment leases that do contain renewal options, thus, the options are not considered in determining the lease term and payments associated with the option years are excluded from lease payments.

For the Company’s equipment leases, the Company used and will use the implicit rate in the lease as the discount rate, when available. Otherwise, the Company uses its incremental borrowing rate as the discount rate. For the Company’s office leases, the implicit rate is typically not available, so the Company used and will use its incremental borrowing rate as the discount rate. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments. The Company’s lease agreements include both lease and non-lease components.

Payments due under the Company’s operating leases include fixed payments as well as variable payments. For the Company’s office leases, variable payments include amounts for the Company’s proportionate share of operating expenses, utilities, property taxes, insurance, common area maintenance and other facility-related expenses. For the Company’s equipment leases, variable payments may consist of sales taxes, property taxes and other fees.

Revenue Recognition

Revenue Recognition

Revenue is recognized at the time and in an amount that reflects the consideration expected to be received for the performance obligations that have been provided. ASC Topic 606 – Revenue from Contracts with Customers (“ASC 606”) defines contracts as written, oral and through customary business practice. Under this definition, the Company considers contracts to be created at the time that the rental service is authorized or an order to purchase product is agreed upon regardless of whether or not there is a written contract.

The Company has three separate and distinct performance obligations offered to its customers: a rental service performance obligation, a product sale performance obligation and a service performance obligation. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer and is defined as the unit of account for revenue recognition under ASC 606. These performance obligations are related to separate revenue streams and at no point are they combined into a single transaction. Sources of net revenues include commercial insurance payers, government insurance payers, medical facilities and patients.

The Company generates its revenues from the rental of infusion pumps to its customers and from product sales and services. For the rental service performance obligation, revenue is based on its standalone price, determined by using reimbursement rates established by third-party payer or other contracts. Revenue is recognized in the period in which the related performance obligation is satisfied, which is typically at the point in time that a patient concludes a treatment, or in certain arrangements, based on the number of pumps that a facility has onsite. The Company’s revenues related to product sales are recognized at the time that control of the product has been transferred to the customer; either at the time the product is shipped or the time the product has been received by the customer, depending on the delivery terms. The Company does not commit to long-term contracts to sell customers a certain minimum quantity of products. The Company's revenues related to services are recognized at the time that the service work has been completed.

The Company employs certain significant judgments to estimate the dollar amount of revenue, and related concessions, allocated to the rental service. These judgments include, among others, the estimation of variable consideration. Variable consideration, specifically related to the Company’s third-party payer rental revenues, is estimated as implied price concessions resulting from differences between the rates charged for services performed and the expected reimbursements for commercial payers and other implied customer concessions. The estimates for variable consideration are based on historical collections with similar payers, aged accounts receivable by payer class and payer correspondence using the portfolio approach, which provide a reasonable basis for estimating the variable portion of a transaction. The Company doesn’t believe it is probable that a significant reversal of revenue will occur in future periods because (i) there is no significant uncertainty about the amount of considerations that are expected to be collected based on collection history and (ii) the large number of sufficiently similar contracts allows the Company to adequately estimate the component of variable consideration.

Net revenues are adjusted when changes in estimates of variable consideration occur. Changes in estimates typically arise as a result of new information obtained, such as actual payment receipt or denial, or pricing adjustments by payers. Subsequent changes to estimates of transaction prices are recorded as adjustments to net revenue in the period of the change. Subsequent changes that are determined to be the result of an adverse change in the payer’s ability to pay are recorded as an allowance for doubtful accounts.

Due to the nature of the industry and the reimbursement environment in which the Company operates, certain estimates are required to record net revenues and accounts receivable at their net realizable values. Inherent in these estimates is the risk that the estimates will have to be revised or updated as additional information becomes available. Specifically, the complexity of many third-party billing arrangements and the uncertainty of reimbursement amounts for certain services from certain payers may result in adjustments to amounts originally recorded. Due to continuing changes in the health care industry and third-party reimbursement, it is possible that management’s estimates could change in the near term, which could have a material impact on the Company’s results of operations and cash flows.

Cost of Revenues

Cost of Revenues

Cost of revenues include the costs of servicing and maintaining pumps, products and services sold, shipping and other direct and indirect costs related to net revenues. Shipping and handling costs incurred after control over a product has transferred to a customer are accounted for as a fulfillment cost.

Customer Concentration

Customer Concentration

As of December 31, 2022, the Company had contracts with nearly 800 third-party payer networks, an increase of 4% over the prior year period. Material terms of contracts with third-party payer organizations are typically a pre-negotiated fee

schedule rate or a then-current proprietary fee schedule rate for equipment and supplies provided. The majority of these contracts generally provide for a term of one year, with automatic one-year renewals, unless the Company or the contracted payer elect not to renew. The Company also contracts with various other third-party payer organizations, Medicaid, commercial Medicare replacement plans, self-insured plans, facilities of its Medicare patients and numerous other insurance carriers. No single payer or customer represented more than 10% of the Company's net revenue in 2022, 2021 or 2020.

Income Taxes

Income Taxes

The Company recognizes deferred income tax liabilities and assets based on (i) the differences between the financial statement carrying amounts and the tax basis of assets and liabilities, using enacted tax rates in effect in the years the differences are expected to reverse and (ii) the tax credit carryforwards. Deferred income tax (expense) benefit results from the change in net deferred tax assets or deferred tax liabilities. A valuation allowance is recorded when it is more likely than not that some or all of any deferred tax assets will not be realized.

Provisions for federal, state and foreign taxes are calculated based on reported pre-tax earnings based on current tax law and include the cumulative effect of any changes in tax rates from those used previously in determining deferred tax assets and liabilities. Certain items of income and expense are recognized in different time periods for financial reporting than for income tax purposes; thus, such provisions differ from the amounts currently receivable or payable.

The Company follows a two-step approach for recognizing uncertain tax positions. First, it evaluates the tax position for recognition by determining if the weight of available evidence indicates it is more-likely-than-not that the position will be sustained upon examination. Second, for positions that are determined are more-likely-than-not to be sustained, it recognizes the tax benefits as the largest benefit that has a greater than 50% likelihood of being sustained. The Company establishes a reserve for uncertain tax positions liability that is comprised of unrecognized tax benefits and related interest and penalties. The Company adjusts this liability in the period in which an uncertain tax position is effectively settled, the statute of limitations expires for the relevant taxing authority to examine the tax position, or more information becomes available.

The Company adopted Accounting Standards Update ("ASU") 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes, in the fourth quarter of 2019. This guidance simplifies various aspects related to accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The guidance was effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. Early adoption was permitted, including adoption in any interim period for which financial statements had not yet been issued. Certain amendments may have been applied on a retrospective, modified retrospective or prospective basis. As permitted, the Company elected to early adopt this guidance for the year ended December 31, 2019. The adoption of this guidance did not have a significant impact on the Company’s financial statements and primarily resulted in the reclassification of an immaterial amount from non-income tax expense to income tax expense related to the accounting for franchise taxes, with no impact to the Company’s consolidated net income, equity or cash flows.

Treasury Stock

Treasury Stock

The Company periodically repurchases shares of its common stock. These repurchases take place either as part of a board-authorized program, which may include open market transactions or privately negotiated transactions and may be made under a Rule 10b5-1 plan, or in targeted stock purchase agreements approved by the board. Treasury stock is accounted for using the par value method. In 2021, the Company retired the approximately 3,500,000 shares that were previously held in treasury. As of December 31, 2022, the Company does not have any shares being held in treasury.

Share-Based Payments

Share-Based Payments

The Company determines the fair value of stock option awards, restricted stock awards and stock appreciation rights (collectively, “Share-Based Awards”) on the date of grant using either the grant date price of the Company's common stock or option-pricing models which are affected by the Company’s stock price, as well as assumptions regarding a number of other inputs using the Black-Scholes pricing model. These variables include the Company’s expected stock price volatility over the expected term of the Share-Based Awards, actual and projected employee stock option exercise behaviors, risk-free interest rates and expected dividends. The expected volatility is based on the historical volatility. The expected term represents the period over which the Share-Based Awards are expected to be outstanding. The dividend yield is an estimate of the expected dividend yield on the Company’s stock. The risk-free rate is based on U.S. Treasury yields in effect at the time of the grant for the expected term of the Share-Based Awards. Forfeitures are recognized as they occur. All Share-Based Awards are amortized based on their graded vesting over the requisite service period of the awards. Compensation costs are recognized over the requisite service period using the accelerated method and included in general and administrative expenses.

Additionally, the Company also determines the fair value of performance-based restricted stock units (“PSUs”) based upon the type of performance measure. These awards typically vest after the Company’s achievement of either a specific Company performance metric or when the market value of the Company’s stock meets a specific metric such as when the closing price of the Company's stock reaches a target value for a minimum number of consecutive trading days. Under Financial Accounting Standards Board (“FASB”) ASC Topic 718, the provisions of the PSUs that vest upon achievement of a target market value are considered a market condition, and therefore the effect of that market condition is reflected in the grant date fair value for this type of award. A third-party valuation expert was engaged to prepare a “Monte Carlo simulation” to account for the market condition to assist management in its conclusion of fair value. That simulation takes into account the beginning stock price of the Company’s common stock, the expected volatilities for the Company’s stock price and the expected risk-free rate of return. The single grant-date fair value computed by this valuation method is recognized by the Company in accounting for the awards regardless of the actual future outcome of the market condition. Compensation costs are accelerated if the market condition is satisfied prior to the end of the service period derived under the Monte Carlo simulation. The grant date fair value of the other PSUs is calculated as the closing price of the Company’s common stock on the grant date multiplied by the number of shares estimated to be delivered subject to the award terms. Company performance measure goals are considered a performance condition and the timing and amount of compensation cost for those PSUs corresponds with management’s expectation of the probable outcome of the performance conditions as of the grant date and during the vesting period.

Deferred Debt Issuance Costs

Deferred Debt Issuance Costs

Capitalized debt issuance costs as of December 31, 2022 and 2021 relate to the Company’s credit facility. The costs related to the agreement are netted against current and non-current debt. The Company amortizes these costs using the interest method through the maturity date of the underlying debt.

Earnings Per Share

Earnings Per Share

The Company reports its earnings per share which includes the presentation of both basic and diluted earnings per share on the statements of operations. The diluted weighted average common shares include adjustments for the potential effects of outstanding stock options but only in the periods in which such effect is dilutive under the treasury stock method. Included in our basic and diluted weighted average common shares are those stock options and restricted stock awards due to participants granted from the 2014 and 2021 stock incentive plans. Anti-dilutive stock awards are comprised of stock options and unvested restricted stock awards, which would have been anti-dilutive in the application of the treasury stock method. In periods where the Company records a net loss, the diluted per share amount is the same as the basic per share amount.

Derivatives

Derivatives

The Company recognizes all derivative financial instruments as cash flow hedges which are shown as either assets or liabilities on the Company’s consolidated balance sheets at fair value. For derivative contracts which can be classified as a cash flow hedge, the effective portion of the change in fair value of the derivative is recorded to accumulated other comprehensive income (“AOCI”) in the consolidated balance sheets. The underlying hedge transaction is realized when the interest payments

on debt are accrued; the applicable amount of gain or loss included in AOCI is reclassified into earnings in the consolidated statements of operations on the same line as the gain or loss on the hedged item attributable to the hedged risk. The cash flows from derivatives are classified as operating activities.

The Company maintains a policy of requiring that all derivative instruments be governed by an International Swaps and Derivatives Association Master Agreement and settles on a net basis.

The fair values of the Company’s derivative financial instruments are categorized as Level 2 of the fair value hierarchy as the values are derived using the market approach based on observable market inputs including quoted prices of similar instruments and interest rate forward curves.

Fair Value of Financial Instruments

Fair Value of Financial Instruments

The carrying amounts reported in the consolidated balance sheets as of December 31, 2022 and 2021 for cash, accounts receivable, accounts payable and other current liabilities approximate fair value because of the short-term nature of these instruments (Level I). The carrying value of the Company’s long-term debt with variable interest rates approximates fair value based on instruments with similar terms (Level II).

The Company has adopted ASC 820, Fair Value Measurements, which defines fair value, establishes a framework for assets and liabilities being measured and reported at fair value and appends disclosures about fair value measurements.

For financial assets and liabilities measured at fair value on a recurring basis, fair value is the price the Company would receive to sell an asset or pay to transfer a liability in an orderly transaction with a market participant at the measurement date. A three-level fair value hierarchy prioritizes the inputs used to measure fair value as follows:

Level I:    quoted prices in active markets for identical instruments;

Level II:    quoted prices in active markets for similar instruments, quoted prices for identical instruments in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the instrument; and

Level III:    significant inputs to the valuation model are unobservable.

Recent Accounting Pronouncements and Developments

Recent Accounting Pronouncements and Developments

The Company has adopted ASU 2020-04, Reference Rate Reform (Topic 848), which contains optional expedients for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Inter-bank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. In January 2021, the FASB issued ASU 2021-01, "Reference Rate Reform (Topic 848): Scope." This ASU clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The Company has elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for LIBOR-indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. The Company continues to evaluate the impact of the guidance and may apply other elections as applicable as additional changes in the market occur.

In June 2016, the FASB issued ASU No. 2016-13, “Financial Instruments (Topic 326) Credit Losses”. Topic 326 changes the impairment model for most financial assets and certain other instruments. Under the new standard, entities holding financial assets and net investment in leases that are not accounted for at fair value through net income are to be presented at the net amount expected to be collected. An allowance for credit losses will be a valuation account that will be deducted from the amortized cost basis of the financial asset to present the net carrying value at the amount expected to be collected on the financial asset. Topic 326 was originally effective as of January 1, 2020, although in November 2019, the FASB delayed the effective date until fiscal years beginning after December 15, 2022 for SEC filers eligible as of the FASB's deferral date to be smaller reporting companies under the SEC’s definition. The Company qualified as a smaller reporting company in November 2019 when the FASB delayed the effective date of Topic 326. Early adoption is permitted. The Company is currently evaluating the impact of Topic 326 on its consolidated balance sheets, statements of operations, statements of cash flows and related disclosures.
