NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

InfuSystem Holdings, Inc. (the “Company”) is a leading provider of infusion pumps and related services. The Company services hospitals, oncology practices and other alternate 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, and Ontario, Canada.

The accompanying consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial information. Accordingly they do not include all of the information and notes required by U.S. Generally Accepted Accounting Principles (“GAAP”) for complete financial statements. The accompanying consolidated financial statements include all adjustments, composed of normal recurring adjustments, considered necessary by management to fairly state our 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 consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in our Annual Report on Form 10-K for the year ended December 31, 2013 (“2013 Form 10-K”) as filed with the SEC.

The consolidated financial statements are prepared in conformity with U.S. 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. We believe 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.

Medical equipment consisted of the following as of March 31, 2014 and December 31, 2013 (in thousands):

Depreciation expense for medical equipment for the three months ended March 31, 2014 was $0.7 million compared to $1.2 million for the same prior year period, which was recorded in cost of revenues – pump depreciation and disposals, respectively.

During the first quarter of 2014, the Company reassessed the estimated useful life of certain of its property and equipment. As a result, the estimated useful life of the Company’s medical equipment was changed from five to seven years due to the determination that the Company was using these assets longer than originally anticipated. A major factor in this change was the servicing of such equipment by the Company’s Kansas facility, which was acquired in 2010. As a result, disposal of such equipment has decreased significantly since that acquisition.

The change in the estimated useful lives of the Company’s pump equipment was accounted for as a change in accounting estimate, on a prospective basis, effective January 1, 2014. The change in estimated useful lives resulted in $0.5 million in less depreciation expense for the quarter ended March 31, 2014 than otherwise would have been recorded. After tax impact, net income would have been lower by $0.3 million, if this change in estimate had not been made. There was no impact to the basic or diluted income per share due to this change in estimate.

Depreciation expense for property and equipment (other than medical equipment) for both the three months ended March 31, 2014 and 2013 was $0.1 million, respectively, which was recorded in general and administrative expenses.

Medical equipment held for sale or rental includes approximately $0.8 million of pre-owned equipment received from a financial institution when such equipment came off lease. Under the Company’s arrangement with the financial institution, the Company does not pay for the equipment until it is sold. The liability for this equipment is included in other current liabilities for a similar amount. The Company assumes risk of loss and accounts for the disposition of such equipment as a sale.

The carrying amount and accumulated amortization of intangible assets as of March 31, 2014 and December 31, 2013, are as follows (in thousands):

Amortization expense for the three months ended March 31, 2014 and 2013 was $0.6 million and $0.7 million, respectively. Expected annual amortization expense for intangible assets recorded as of March 31, 2014, is as follows (in thousands):

On November 30, 2012, the Company entered into a credit agreement with Wells Fargo as Administrative Agent and Wells Fargo and PennantPark as Lenders. The credit agreement consists of a $12.0 million Term Loan A (provided by Wells Fargo), a $14.5 million Term Loan B (provided by PennantPark) and a $10.0 million revolving credit facility (the “Revolver”), all of which mature on November 30, 2016, collectively (the “Credit Facility”). Interest on the Credit Facility is payable at the Company’s choice of LIBOR plus 7.25% (with a LIBOR floor of 2.0%) or the Wells Fargo prime rate plus 6.25% (with a prime rate floor of 3.0%). As of March 31, 2014, interest was payable at the Wells Fargo prime rate plus 6.25%, which equaled 9.50%.

Table of Contents

The availability under the revolving Credit Facility is based upon the Company’s eligible accounts receivable and eligible inventory. The Company had revolving loan gross availability of $6.9 million and $5.9 million, respectively, outstanding amounts on the Revolver included $0.6 million at March 31, 2014 and a reserve amount of $0.1 million and $0.0 million, respectively, on a letter of credit at March 31, 2014 and December 31, 2013, leaving approximately $6.2 million and $5.9 million available under the revolving Credit Facility as of March 31, 2014 and December 31, 2013, respectively.

The Credit Facility is collateralized by substantially all of the Company’s assets and requires the Company 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 an annual limit on capital expenditures, including capital leases. As of March 31, 2014, the Company was in compliance with all such covenants and expects to be in compliance over the next 12 months.

In connection with the Credit Facility, the Company has the following covenant obligations for the duration of the facility:

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 had approximate future maturities of loans and capital leases as of March 31, 2014 as follows (in thousands):

The following is a breakdown of the Company’s current and long-term debt (including capital leases) as of March 31, 2014 and December 31, 2013 (in thousands):

During the three months ended March 31, 2014 and 2013, we recorded income tax expense of $0.3 million and $0.1 million, respectively. The increase is tax expense was primarily due to profitability during the quarter ended March 31, 2014. In computing its income tax provision, the Company estimates its effective tax rate for the full year and applies that rate to income earned though the reporting period. The effective income tax rate was 37.4% and 43.4% for the quarters ended March 31, 2014 and 2013, respectively.

The Company is currently involved in legal proceedings arising out of the ordinary course and conduct of our business, the outcomes of which are not determinable at this time. We have insurance policies covering potential losses where such coverage is cost effective. In the Company’s opinion, any liability that might be incurred by us upon the resolution of these claims and lawsuits will not, in the aggregate, have a material effect on the Company’s consolidated 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 months ended March 31, 2014, vested stock options of 0.1 million were not included in the calculation because they were not in-the-money.

On April 11, 2014, the Company repaid $1.6 million on its Credit Facility for its annual Excess Cash Flow sweep as required and defined by the Company’s Credit Agreement dated November 30, 2012.

Overview

We are a leading provider of infusion pumps and related services. We service hospitals, oncology practices and other alternate 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, and Ontario, Canada.

InfuSystem Holdings, Inc. Results of Operations for the three months ended March 31, 2014 compared to the three months ended March 31, 2013

Revenues

Our revenue for the quarter ended March 31, 2014 was $17.2 million, an increase of $2.5 million, or 17%, compared to $14.7 million for the quarter ended March 31, 2013. During the period, net revenues from rentals increased 10% while net revenues from product sales increased 90% over the same period in 2013. An opportunistic product sale, during the period, of a particular pump at a low gross margin resulted in $0.9 million in additional revenue, without which, revenues from product sales would have increased 19% and total revenues would have increased 11% over the prior year period. The remaining increase in revenues was primarily related to the addition of larger customers and increased penetration into our existing customer accounts.

Gross Profit

Gross profit for the quarter ended March 31, 2014 was $12.1 million, an increase of $1.7 million, or 16%, compared to gross profit of $10.4 million for the quarter ended March 31, 2013. Gross profit, as a percentage of revenues, represented 70% and 71% for the three months ended March 31, 2014 and 2013, respectively. Without the aforementioned opportunistic pump sale, gross profit for the current period would have been 74%.

During the first quarter of 2014, we reassessed the estimated useful life of certain property and equipment. As a result, the estimated useful life of our medical equipment was changed from five to seven years due to the determination that we were using these assets longer than originally anticipated. A major factor in this change was the servicing of such equipment by our Kansas facility, which was acquired in 2010. As a result, disposal of such equipment has decreased significantly since that acquisition.

The change in the estimated useful lives of our pump equipment was accounted for as a change in accounting estimate, on a prospective basis, effective January 1, 2014. The change in estimated useful lives resulted in $0.5 million less depreciation expense for the quarter ended March 31, 2014 than otherwise would have been recorded. As a result, cost of revenues in the current period is $0.5 million less than the same prior year period.

Provision for Doubtful Accounts

Provision for doubtful accounts for the quarter ended March 31, 2014 was $2.1 million, an increase of $0.4 million, or 27%, compared to $1.7 million for the quarter ended March 31, 2013. The provision for doubtful accounts was 12% of revenues at March 31, 2014 compared to 11% for the same period in the prior year. A large part of the Company’s provision for doubtful accounts can be attributed to a major group of third party payors that revised their claim processing guidelines at the end of 2012 that continues to affect all durable medical equipment (“DME”) providers. Prior to the change, DME providers submitted claims to their “home plan” and the claims were processed in-network. Since the change in guidelines, DME providers are now required to submit their claims to the payor in the state where services were initiated. If the DME provider is not a participating provider with that specific payor, the claim is treated as out-of-network and the patient will incur higher costs. Therefore, we must collect a higher portion of reimbursement directly from patients, which creates an increased collection risk. This major payor’s association selected us as a preferred provider, which will help us in securing contracts in areas currently out-of-network.

Amortization of Intangible Assets

Amortization of intangible assets for the quarter ended March 31, 2014 was $0.6 million, a 1% decrease compared to the quarter ended March 31, 2013 of $0.7 million.

Selling and Marketing Expenses

During the quarter ended March 31, 2014, our selling and marketing expenses were $2.7 million, an increase of $0.3 million, or 10%, compared to $2.4 million for the quarter ended March 31, 2013. This increase was largely attributed to increased commissions based on higher revenue for the comparable periods. 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 March 31, 2014, our G&A expenses were $4.9 million, which is consistent with the $5.0 million for the quarter ended March 31, 2013. This maintaining of previous G&A spending levels is due to an increase during the current period in information technology costs of $0.1 million, an increase in new product services by $0.1 million, an increase in cash versus stock compensation of $0.1 million, and a decrease in other G&A expenses by $0.1 million. In the prior year period, the Company experienced certain expenses (“Transition Costs”) of $0.3 million associated with a CEO search, the final severance payment made to the former CEO, and a one-time payment to an exiting Board member. General and administrative expense (“G&A”) during these periods consisted primarily of accounting, administrative, third party payor billing and contract services, customer service, nurses on staff, new product services, and service center personnel salaries, fringe benefits and other payroll related items, professional fees, legal fees, stock based compensation, insurance and other miscellaneous items.

Other Income and Expenses

During the quarter ended March 31, 2014, we recorded interest expense of $0.8 million, which was consistent with the same prior year period. In addition, during the first quarter of 2013, we received other income of $0.3 million in proceeds when a mutual insurance company we maintained a policy with was acquired and cash payments were disbursed to eligible members.

Income Taxes

During the quarter ended March 31, 2014, we recorded income tax expense of $0.3 million compared to less than $0.1 million during the quarter ended March 31, 2013. The increase in tax expense was primarily due to profitability during the quarter ended March 31, 2014.

Liquidity and Capital Resources

As of March 31, 2014, we had cash or cash equivalents of $0.5 million and $6.2 million of availability on the Credit Facility compared to $1.1 million of cash and cash equivalents and $5.9 million of availability on the Credit Facility at December 31, 2013. During the quarter ended March 31, 2014, accounts receivable, net increased $1.4 million compared to December 31, 2013, primarily due to the increase in revenue, the impact of copays and deductibles for patients’ insurance that traditionally reset at the beginning of each year and billings late in the quarter.

Cash used in operating activities for the three months ended March 31, 2014 was $0.6 million compared to cash generated of $1.6 million for the three months ended March 31, 2013. The decrease in cash is primarily due to increases in accounts receivable in 2014. The cash flow effect from this change in accounts receivable is a decrease of $0.8 million more than the decrease in the same quarter last year. Additionally, operating cash flow decreased due to a significant decrease of $1.8 million in accounts payable and other current liabilities.

Cash proceeds from investing activities was $0.1 million for the three months ended March 31, 2014, compared to cash used of $0.7 million for the three months ended March 31, 2013. The increase is primarily related to less purchases of medical equipment and property of $0.2 million and an increase in the proceeds from the sale of medical equipment and property of $0.6 million compared to the same period in the prior year. The significant increase was largely due to the opportunistic sale of a particular pump that resulted in $0.9 million and the sale of our pre-owned equipment received from a financial institution resulted in $0.4 million, of which a total of $0.4 million was collected during the quarter.

Cash used in financing activities for the three months ended March 31, 2014 was $0.1 million compared to $2.8 million used for financing activities for the three months ended March 31, 2013. This decrease is mainly attributed to the need to draw down less on the revolving credit facility in the period ended March 31, 2014 and better cash management.

Availability under the revolving credit facility is based upon the Company’s eligible accounts receivable and eligible inventory. The Company had revolving loan gross availability of $6.9 million and $5.9 million, respectively, and outstanding amounts totaling $0.6 million and $0.0 million, as well as a reserve for a letter of credit of $0.1 million, leaving approximately $6.2 and $5.9 million, respectively, available under the revolving credit facility as of March 31, 2014 and December 31, 2013.

The Credit Facility is collateralized by substantially all of the Company’s assets and requires the Company 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 an annual limit on capital expenditures, including capital leases. As of March 31, 2014, the Company was in compliance with all such covenants and expects to be in compliance for the next 12 months.

Critical Accounting Policies and Estimates

The 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 consolidated financial statements and the judgments and assumptions used are consistent with those described in the MD&A section in our 2013 Form 10-K.

Evaluation of Disclosure Controls and Procedures

Eric K. Steen, our Chief Executive Officer (“CEO”), and Jonathan P. Foster, our Chief Financial Officer (“CFO”), have performed an evaluation of the Company’s disclosure controls and procedures, as that term is defined in Rule 13a-15(e) of the Securities Exchange Act of 1934, as amended (“Exchange Act”), as of March 31, 2014, and each has concluded that such disclosure controls and procedures are effective to ensure that information required to be disclosed in our periodic reports filed under the Exchange Act is recorded, processed, summarized, and reported within the time periods specified by SEC rules and forms, and that such information is accumulated and communicated to the CEO and CFO to allow timely decisions regarding required disclosures.

Management’s Report on Internal Control Over Financial Reporting

Our 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). The 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.

All internal control systems, no matter how well designed, have inherent limitations. Therefore, even those systems determined to be effective can provide only reasonable assurance with respect to financial statement preparation and presentation. 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 because the degree of compliance with policies or procedures may deteriorate.

Under the supervision and with the participation of the CEO and CFO, management conducted an assessment of the effectiveness of our internal control over financial reporting as of March 31, 2014. The assessment was based on criteria established in the framework Internal Control - Integrated Framework (1992), issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on its evaluation, management concluded that our internal control over financial reporting was effective as of March 31, 2014.

Change in Internal Control Over Financial Reporting

We have made no changes during the three months ended March 31, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
