NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The terms “InfuSystem”, “the Company”, “we”, “our” and “us” are used herein to refer to InfuSystem Holdings, Inc. and its subsidiaries. InfuSystem Holdings, Inc. is a leading provider of infusion pumps and related services. The Company services hospitals, oncology practices and other alternative site healthcare providers. Headquartered in Madison Heights, Michigan, the Company delivers local, field-based customer support, and also operates pump repair Centers of Excellence in Michigan, Kansas, California, Texas, Georgia and Ontario, Canada.

The accompanying unaudited condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly, the unaudited condensed consolidated financial statements do not include all of the information and notes required by U.S. Generally Accepted Accounting Principles (“GAAP”) for complete financial statements. The accompanying unaudited condensed consolidated financial statements include all adjustments, composed of normal recurring adjustments, considered necessary by management to fairly state the Company’s results of operations, financial position and cash flows. The operating results for the interim periods are not necessarily indicative of results that may be expected for any other interim period or for the full year. These unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC.

The unaudited condensed consolidated financial statements are prepared in conformity with GAAP, which requires the use of estimates, judgments and assumptions that affect the amounts of assets and liabilities at the reporting date and the amounts of revenue and expenses in the periods presented. The Company believes that the accounting estimates employed are appropriate and the resulting balances are reasonable; however, due to the inherent uncertainties in making estimates, actual results could differ from the original estimates, requiring adjustments to these balances in future periods.

On April 20, 2015 (the “Closing Date”), the Company acquired substantially all of the assets of Ciscura Holding Company, Inc. and its subsidiaries (“Ciscura”) for $6.2 million in cash, based on the final number of pumps acquired and the associated treatments, which were generated during the 90-day period post-closing from the approximately 100 medical facility relationships Ciscura had prior to the acquisition. The Company acquired approximately 1,800 infusion pumps, its four-person field sales team, as well as its facilities management personnel, which have become the foundation of the Company’s new Southeast facility. Ciscura, based in Alpharetta, GA, was a privately-held Southeastern regional provider of ambulatory infusion pumps and services to medical facilities and provides the Company with a new regional warehouse and service facility that are in close proximity to a number of our largest existing customers, in addition to new customers previously serviced by Ciscura, enabling same day service for equipment and supplies to much of the Southeast region. The Company used available borrowings under its Credit Facility to finance the acquisition and associated expenses.

Final Purchase Price Allocation

Pursuant to Accounting Standards Codification (“ASC”) 805, Business Combinations, the final purchase price was allocated to the assets acquired and liabilities assumed based upon their fair values as of the Closing Date. The final purchase price allocation was primarily based upon a valuation using income and cost approaches and management’s estimates and assumptions. The allocation of the final purchase price to the fair values of the assets acquired and liabilities assumed as of the Closing Date is presented below (in thousands):

Unaudited Pro Forma Financial Information

The unaudited pro forma financial information in the table below summarizes the combined results of operations of the Company and Ciscura as though the companies had been combined as of the beginning of the three and six month periods ended June 30, 2015. The pro forma financial information is presented for informational purposes only and is not indicative of the results of operations that would have been achieved if the acquisition had taken place at the beginning of the period presented nor is it indicative of future results. The Company did not disclose the revenue and income of Ciscura separately as it is not practical due to the fact that the operations are substantially integrated. The following pro forma financial information presented also includes the pro forma depreciation and amortization charges from acquired tangible and intangible assets, and related tax effects for the three and six months ended June 30, 2015 (in thousands):

Medical equipment consisted of the following as of June 30, 2016 and December 31, 2015 (in thousands):

Depreciation expense for medical equipment for the three and six months ended June 30, 2016 was $1.6 million and $3.1 million, respectively, compared to $1.1 million and $2.1 million for the same prior year periods, which was recorded in cost of revenues – pump depreciation and disposals, for each period.

Depreciation expense for property and equipment for the three and six months ended June 30, 2016 was $0.1 million and $0.3 million, respectively, compared to $0.1 million and $0.2 million for the same prior year periods. This expense was recorded in general and administrative expenses.

Borrower’s choice as a (i) Eurodollar Loan, which bears interest at a per annum rate equal to LIBOR plus a margin ranging from 2.00% to 2.50% or (ii) CBFR Loan, which bears interest at a per annum rate equal to (a) the Lender’s prime rate or (b) LIBOR for a 30-day interest period plus 2.50%, in each case, plus a margin ranging from -0.75% to -0.25%. The actual rate at June 30, 2016 was 2.95% (LIBOR of 0.45% plus 2.50%) on both Term Loan A and B and 3.25% (JPM Chase Prime Rate of 3.5% less 0.25%) on the Revolver.

The availability under the Revolver is based upon the Borrowers’ eligible accounts receivable and eligible inventory and is comprised as follows (in thousands):

To secure repayment of the obligations of the Borrowers, each Borrower has granted to the Lender, 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. In addition, the Company has pledged the shares of InfuSystem Holdings USA, Inc. (“Holdings USA”) and Holdings USA has pledged the shares of each of InfuSystem, Inc. and First Biomedical, Inc. and the equity interests of IFC, LLC to the Lender, for the benefit of the secured parties, to further secure the obligations under the Credit Agreement.

In addition, the Credit Agreement requires the Borrowers to maintain the following financial covenant obligations:

As of June 30, 2016, the Borrowers were in compliance with all such covenants.

The Company occasionally enters into capital leases to finance the purchase of ambulatory infusion pumps. The pumps are capitalized into medical equipment in rental service at their fair market value, which equals the value of the future minimum lease payments and are depreciated over the useful life of the pumps.

The Company’s effective income tax rate for the six months ended June 30, 2016 was 37.2% compared to 39.7% for the same prior year period.

From time to time in the ordinary course of its business, the Company may be involved in legal proceedings, the outcomes of which may not be determinable. The Company has insurance policies covering potential losses where such coverage is cost effective. The Company is not, at this time, involved in any legal proceedings that the Company believes could have a material effect on the Company’s financial condition, results of operations or cash flows.

Basic income per share is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted income per share assumes the issuance of potentially dilutive shares of common stock during the period. The following table reconciles the numerators and denominators of the basic and diluted income per share computations:

For the three and six months ended June 30, 2016, less than 0.1 million of stock options were not included in the calculation because they would have an anti-dilutive effect, compared to 0.1 million for the same prior year periods.

The Company has evaluated subsequent events through the date of issuance for the unaudited condensed consolidated financial statements as of June 30, 2016.

In April 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2015-03, Interest – Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs (“ASU 2015-03”), and, in August 2015, the FASB issued ASU No. 2015-15, Interest – Imputation of Interest (Subtopic 835-30): Presentation and Subsequent Measurement of Debt Issuance Costs Associated with Line-of-Credit Arrangements - Amendments to SEC Paragraphs Pursuant to Staff Announcement at June 18, 2015 EITF Meeting (“ASU 2015-15”). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-15 then clarified that debt issuance costs related to a line-of-credit arrangement can be presented as an asset on the balance sheet, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. These ASUs are effective for fiscal years beginning after December 15, 2015, and for interim periods within those fiscal years. The Company adopted this guidance as of January 1, 2016, and as a result, has recast the December 31, 2015 consolidated balance sheet to conform to the current period presentation. The adoption of this standard reduced previously presented other assets and long-term debt by $0.1 million, based upon the balance of unamortized debt issuance costs relating to its Credit Facility as of December 31, 2015.

In July 2015, the FASB issued ASU No. 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory (“ASU 2015-11”), requiring that inventory be measured at the lower of cost and net realizable value. Net realizable value is defined as estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. ASU 2015-11 is effective within annual periods beginning on or after December 15, 2016, including interim periods within that reporting period. The Company is currently evaluating the impact, if any, that the adoption of this guidance will have on its financial position, results of operations, cash flows and/or disclosures.

Table of Contents

On May 28, 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. ASU 2014-09 will supersede the existing revenue recognition guidance in U.S. GAAP when it becomes effective and permits the use of either a retrospective or cumulative effect transition method. In August 2015, the FASB issued ASU No. 2015-14, deferring the effective date of ASU 2014-09 by one year, from January 1, 2017 to January 1, 2018. The Company plans to adopt ASU 2014-09 on January 1, 2018. The Company is evaluating the effect that ASU 2014-09 will have on its financial position, results of operations, cash flows and/or disclosures and has not yet selected a transition method.

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes (“ASU 2015-17”), simplifying the balance sheet classification of deferred taxes by requiring all deferred taxes, along with any related valuation allowance, to be presented as noncurrent. ASU 2015-17 is effective for the Company beginning in the first quarter of 2017 and allows for early adoption and may be applied either prospectively or retrospectively. ASU 2015-17 is not expected to have a material impact on the Company’s financial position, results of operations, cash flows and/or disclosures.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments – Overall: Recognition and Measurement of Financial Assets and Financial Liabilities (“ASU 2016-01”). ASU 2016-01 affects the accounting for equity investments, financial liabilities under the fair value option and the presentation and disclosure requirements of financial instruments. ASU 2016-01 is effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. The Company is currently evaluating the impact, if any, that the adoption of this guidance will have on its financial position, results of operations, cash flows and/or disclosures.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02”). Under ASU 2016-02, an entity will be required to recognize right-of-use assets and lease liabilities on its balance sheet and disclose key information about leasing arrangements. ASU 2016-02 offers specific accounting guidance for a lessee, a lessor and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing and uncertainty of cash flows arising from leases. For public companies, ASU 2016-02 is effective for annual reporting periods beginning after December 15, 2018, including interim periods within that reporting period, and requires a modified retrospective adoption, with early adoption permitted. The Company is currently evaluating the impact, if any, that the adoption of this guidance will have on its financial position, results of operations, cash flows and/or disclosures.

Overview

We are a leading provider of infusion pumps and related services. We service hospitals, oncology practices and other alternative site healthcare providers. Headquartered in Madison Heights, Michigan, we deliver local, field-based customer support, and also operate Centers of Excellence in Michigan, Kansas, California, Texas, Georgia and Ontario, Canada.

We supply electronic ambulatory infusion pumps and associated disposable supply kits to oncology practices, infusion clinics and hospital outpatient chemotherapy clinics. These pumps and supplies are utilized mostly by colorectal cancer patients who receive a standard of care treatment that utilizes continuous chemotherapy infusions delivered via electronic ambulatory infusion pumps. Our products and services are also utilized by patients in other disease states such as pancreatic, esophageal, stomach, and other head and neck and gastro intestinal tract cancers, as well as in the management of post-operative pain. We obtain an assignment of insurance benefits from the patient, bill the insurance company or patient accordingly, and collect payment. We provide pump management services for the pumps and associated disposable supply kits to over 1,700 cancer therapy sites in the United States, and except in rare circumstances where the patient has met a payment cap, retain title to the pumps during this process.

We sell or rent new and pre-owned pole mounted and ambulatory infusion pumps to, and provide biomedical recertification, maintenance and repair services for, oncology practices as well as other alternative site settings including home care and home infusion providers, skilled nursing facilities, pain centers and others.

Additionally, we sell, rent, service and repair new and pre-owned infusion pumps and other medical equipment. We also sell a variety of primary and secondary tubing, cassettes, catheters and other disposable items that are utilized with infusion pumps. Our rental and sales revenues come from three different revenue streams: provider to patient, supplier to supplier, and supplier to provider.

Since 2013, we have made significant investments in our Information Technology (“IT”). These efforts have primarily been focused on increasing electronic connectivity with our customers via electronic medical integration, pump portal, and asset tracking. Since 2014, we have invested in supporting uses of our ambulatory pumps in pain management for outpatient orthopedic surgeries utilizing continuous peripheral nerve block and collecting patient pain scores.

Recent Developments

CMS

On April 25, 2016, CMS released the Medical Learning Network (“MLN”) Matters Number SE1609 “Medicare Policy Clarified for Prolonged Drug and Biological Infusions Started Incident to a Physician’s Service Using an External Pump” clarification article (“SE1609”). This clarification article is intended for all physicians and hospital outpatient departments submitting claims to Medicare Administrative Contractors (“MACs”) for prolonged drug and biological infusions started incident to a physician’s service using an external pump. It should be noted that this article does not apply to suppliers’ claims submitted to Durable Medical Equipment (“DME”) MACs.

We interpret SE1609 as no longer permitting DME suppliers to submit billings to the DME MACs for the infusion pumps and supplies provided to Medicare patients in the circumstances described in SE1609. More particularly, SE1609 provides that when a drug is provided “incident to” physicians’ services rendered to patients while in the physician’s office or hospital outpatient department, the external pump is not separately billable as DME. This applies to any DME supplier, home infusion company, hospital outpatient clinic or physician office that provides ambulatory infusion pumps in a setting where treatment is initiated in the infusion setting prior to the patient being sent home for long term infusion. SE1609 states that an ambulatory infusion pump and supplies are not separately reimbursable as DME when a Medicare patient leaves an infusion setting and goes home with a pump. SE1609 indicates that the administration of the drug billed to the local Medicare Contractor should also include payment for the DME used in furnishing the service. Under existing laws, in order for Medicare to cover the cost of the drug and external pump, a physician, hospital, clinic, home infusion therapy company or DME supplier must incur a cost for the drug and pump.

We have historically submitted billings directly to DME MACs for our infusion pumps and portfolio of related services in the circumstances described above. In this regard, Medicare accounted for 18% and 19% of the Company’s total revenues for the six month period ended June 30, 2016 and fiscal year ended December 31, 2015, respectively, and 17% and 20% of Company’s consolidated accounts receivable, net as of June 30, 2016 and as of December 31, 2015, respectively. As a result of SE1609, we will now submit these billings, effective July 1, 2016, directly to physicians or hospitals who, in turn, will seek reimbursement from Medicare. In these cases, the providing physicians or hospitals, rather than Medicare, will be the primary obligor to the Company for payments for our infusion pumps and portfolio of related services.

It is important to note that SE1609 applies only to Medicare patients and, therefore, we currently expect that SE1609 will have no direct material impact on the majority of patients of the Company’s customers who are insured by private commercial carriers. In these cases, which currently represent a substantial majority of our revenues, we already submit billings directly to these private commercial carriers.

The Company estimates that the transition to the alternative billing arrangement and other recent announcements regarding commercial billing will have a net reduction to its operating income (loss of net revenue net of associated expenses saved) of approximately $1 million annually. Furthermore, there can be no assurance that SE1609 will not further impact future revenues and net income or implicate other risks referred to in the Risk Factors section of the Company’s Annual Report on Form 10-K for 2015.

InfuSystem Holdings, Inc. Results of Operations for the Three and Six Months Ended June 30, 2016 Compared to the Three and Six Months Ended June 30, 2015

Net Revenues

Our net revenues for the quarter ended June 30, 2016 were $19.1 million, an increase of $1.9 million, or 11%, compared to $17.2 million for the quarter ended June 30, 2015. During the period, net revenues from rentals increased $1.6 million, or 10%, compared to the same prior year period. Net revenues from product sales were $1.9 million, an increase of $0.3 million compared to the same prior year period. Our net revenues for the six months ended June 30, 2016 were $38.1 million, an increase of $4.2 million over the same prior year period. The increase in net revenues for both 2016 periods can be attributed to greater rental volume with new and existing sites of therapy, partially offset by a higher mix of Medicaid and patient payors in our rental business, which generally have lower net revenue rates than commercial payors.

Gross Profit

Gross profit for the quarter ended June 30, 2016 was $12.1 million, an increase of $0.2 million, or 2%, compared to $11.9 million for the quarter ended June 30, 2015. Gross profit, as a percentage of net revenues, for the quarter ended June 30, 2016 was 63%, down from 69% for the same prior year period. Gross profit for the six months ended June 30, 2016 was $25.4 million, an increase of $1.5 million, or 6%, compared to the six months ended June 30, 2015. Gross profit, as a percentage of net revenues, for the six months ended June 30, 2016 was 67%, down from 71% for the same prior year period. The decrease in gross profit as a percentage of net revenues for the six months ended June 30, 2016 was mainly due to the increase in rental revenues for the period which was offset by a $2.8 million increase in supply costs and depreciation associated with the increase in rental revenues and the deployment of pumps to new therapy sites.

Provision for Doubtful Accounts

Provision for doubtful accounts for the quarter ended June 30, 2016 was $1.1 million, a decrease of $0.1 million, or 7%, compared to the quarter ended June 30, 2015. The provision for doubtful accounts was 6% of net revenues at June 30, 2016, compared to 7% for the same prior year period. This change is the result of the Company’s increased number of third-party payor contracts that are now being billed at in-network rates with lower rates of bad debt whereby previous insurance billings were billed at higher out-of-network rates with higher rates of bad debt. Bad debt is primarily associated with rental revenues.

Provision for doubtful accounts for the six months ended June 30, 2016 was $2.8 million, an increase of $0.5 million, or 20%, compared to $2.3 million for the six months ended June 30, 2015. The provision for doubtful accounts was 7% of net revenues at June 30, 2016, which was consistent with the same prior year period. This increase is due (i) mainly to a change in a payor that was billing the Company as in-network without a contract to out-of-network, thereby resulting in an increase in bad debt and the Company has recently signed a contract with this payor whereby the billing will resort back to in-network; and (ii) a higher mix of Medicaid and patient payors in our rental business, which generally have high uncollectible rates than commercial payors.

Amortization of Intangible Assets

Amortization of intangible assets for the quarter ended June 30, 2016 was $0.9 million, an increase of $0.2 million compared to the same prior year period. Amortization of intangible assets for the six months ended June 30, 2016 was $1.8 million, an increase of $0.5 million compared to the same prior year period. These increases were largely attributable to the intangible assets acquired from our Ciscura acquisition and the completion of several IT projects that were placed into service and the resulting amortization.

Selling and Marketing Expenses

During the quarter ended June 30, 2016, selling and marketing expenses were $2.3 million, a decrease of $0.4 million, or 14%, compared to $2.7 million for the quarter ended June 30, 2015. During the six months ended June 30, 2016, selling and marketing expenses were $5.1 million, a decrease of $0.3 million, compared to $5.4 million for the same prior year period. These decreases were largely attributable to reductions in sales and marketing personnel costs. Selling and marketing expenses during these periods consisted of sales personnel salaries, commissions and associated fringe benefit and payroll-related items, marketing, share-based compensation, travel and entertainment and other miscellaneous expenses.

General and Administrative Expenses

During the quarter ended June 30, 2016, General and Administrative (“G&A”) expenses were $6.4 million, an increase of $0.4 million, or 7%, from $6.0 million for the quarter ended June 30, 2015. The increase in G&A expenses versus the same prior year period was mainly attributable to increases in spending on IT of $0.9 million and decreases in stock compensation expense and professional fees of $0.5 million. During the six months ended June 30, 2016, G&A expenses were $13.1 million, an increase of 9%, from $12.0 million for the six months ended June 30, 2015. The increase in G&A expense versus the same prior year period was mainly attributable to increases in spending on IT and Pain Management initiatives of $1.1 million.

During the quarter ended June 30, 2016, we recorded interest expense of $0.3 million, a decrease of $0.1 million, or 16%, compared to $0.4 million for the same prior year period. During the six months ended June 30, 2016, we recorded interest expense of $0.6 million, a decrease of $0.4 million, or 40%, compared to $1.0 million for the same prior year period. This is a direct result of the lower interest rates with our new Credit Facility, which we entered into on March 23, 2015, consisting of a $27.0 million Term Loan A, up to an $8.0 million Term Loan B and a $10.0 million revolving credit facility (the “Revolver”), all of which mature on March 23, 2020, collectively (the “Credit Facility”). In addition, during the six months ended June 30, 2015, we had other expenses of $1.6 million, primarily related to the write-off of deferred financing costs as a result of the early extinguishment of debt.

Income Taxes

During the three and six months ended June 30, 2016, we recorded income tax expense of $0.3 million and $0.7 million, respectively. During the three and six months ended June 30, 2015, the Company recorded income tax expense of $0.1 million and a tax benefit of $0.1 million, respectively. Our effective income tax rate for the six months ended June 30, 2016 was 37.2%.

Liquidity and Capital Resources

As of June 30, 2016, we had cash and cash equivalents of $0.8 million and $3.3 million of net availability under the Revolver compared to $0.8 million of cash and cash equivalents and $9.9 million of net availability under our Revolver at December 31, 2015.

As of June 30, 2016, the Company has prepaid its Term Loan A principal payments due on September 30, 2016 and December 31, 2016. Each of these payments is approximately $1.0 million, representing a total prepayment of $1.9 million.

Cash provided by operating activities for the six months ended June 30, 2016 was $1.9 million compared to cash provided by operating activities of $3.8 million for the six months ended June 30, 2015. This decrease is mainly due to increases in accounts receivable and decreases in other current liabilities.

Cash used in investing activities was $5.4 million for the six months ended June 30, 2016 compared to cash used of $11.4 million for the six months ended June 30, 2015. The decrease in cash used was due to $3.8 million of cash used during the six months ended June 30, 2015 related to our Ciscura asset acquisition. The Company has spent approximately $2.5 million on Information Technology capital projects for the year. There was also a decrease in spending on non-pump assets of $0.1 million and a $0.9 million increase in cash used to purchase medical equipment.

Cash proceeds in financing activities for the six months ended June 30, 2016 was $3.5 million compared to cash proceeds of $7.9 million for the six months ended June 30, 2015. This decrease is primarily attributable to the cash proceeds received as a result of our decision to refinance our debt in the first quarter of 2015.

The availability under the Revolver is based upon our eligible accounts receivable and eligible inventory and is computed as follows (in thousands):

Our Credit Facility is collateralized by substantially all of our assets and shares of the Company’s subsidiaries and requires us to comply with covenants, including but not limited to, financial covenants relating to the satisfaction, on a quarterly and annual basis for the duration of the Credit Facility, of a total leverage ratio, a fixed charge coverage ratio and a net worth level. As of June 30, 2016, we were in compliance with all such covenants and expect to remain in compliance for the next 12 months.

Critical Accounting Policies and Estimates

The unaudited condensed consolidated financial statements are prepared in conformity with U.S. GAAP, which require the use of estimates, judgments and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses in the periods presented. We believe that the accounting estimates employed are appropriate and resulting balances are reasonable; however, due to inherent uncertainties in making estimates, actual results could differ from the original estimates, requiring adjustments to these balances in

future periods. The critical accounting estimates that affect the unaudited condensed consolidated financial statements and the judgments and assumptions used are consistent with those described in the MD&A section in our Annual Report on Form 10-K for the year ended December 31, 2015.

Evaluation of Disclosure Controls and Procedures and Changes in Internal Control over Financial Reporting

We maintain a set of disclosure controls and procedures designed to ensure that material information required to be disclosed in our filings under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that material information is accumulated and communicated to our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), as appropriate, to allow timely decisions regarding required disclosures. Our CEO and CFO have evaluated these disclosure controls and procedures as of the end of the period covered by this quarterly report on Form 10-Q and have determined that such disclosure controls and procedures were effective.

There has been no change in our internal control over financial reporting during our most recent calendar quarter that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II—OTHER INFORMATION

We are, from time to time, a party to legal proceedings that may arise in the ordinary course of our business. Currently, there are no legal proceedings that management believes would have a material adverse effect on our consolidated financial condition or results of operations.

For information regarding factors that could affect our results of operations, financial condition and liquidity, refer to the section entitled “Risk Factors” in Part I, Item 1A in our Annual Report on Form 10-K for the year ended December 31, 2015.

Except as updated below, there have been no material changes from the risk factors previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2015 as filed with the SEC. The risk factor below supersedes, in its entirety, the risk factor set forth in Item 1A in our Quarterly Report on form 10-Q for the first quarter of 2016.

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 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 bad debt expense and/or decrease our revenues. Additionally, any regulatory changes that restrict our ability to seek reimbursement for DME, including, but not limited to SE1609, could have a material adverse effect on our business, financial condition, results of operations and cash flows.

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 payors, 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.
