NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(UNAUDITED)

1. Basis of Presentation, Nature of Operations and Summary of Significant Accounting Policies

InfuSystem Holdings, Inc. and Subsidiaries (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, 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. 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 and Form 10-K/A for the year ended December 31, 2012 (the “2012 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.

Revised Presentation in the Consolidated Statements

The Company both rents and sells medical equipment. In the first quarter of 2013, it came to management’s attention that based on promulgation through recent comments from the Staff of the Securities and Exchange Commission greater clarity and consistent classification should be provided in an entity’s financial statements around such assets on the balance sheet and in the statement of cash flows. Specifically, the Staff believed that a company should clearly disclose (i) assets on the balance sheet; and (ii) cash flows when presenting cash flows in relation to, and in consideration of, its predominant source of revenues.

Management believes that the predominant source of revenues and cash flows from this medical equipment is from rentals and that most equipment that the Company has purchased is likely to be rented prior to being sold. The Company first revised its presentation of revenue and cash flows in its Quarterly Report on Form 10-Q for the fiscal quarter ended March 31, 2013 and continues the revised presentation in this report.

While management has concluded that the effect of correcting previous errors in the Company’s financial statements is not material, the Company reclassified certain amounts in its Condensed Consolidated Cash Flows for the six months ended June 30, 2012 to allow for appropriate comparisons between periods presented.

The effect of this reclassification to the Condensed Consolidated Cash Flow Statement was to both reduce Net cash provided by operating activities and reduce Net cash used in investing activities by $1.4 million for the six months ended June 30, 2012.

The corrections and reclassifications described above did not affect the Company’s condensed consolidated statements of operations or total cash flows for the six months ended June 30, 2012.

2. Medical Equipment and Property

Medical equipment consisted of the following as of June 30, 2013 and December 31, 2012 (in thousands):

Depreciation expense for medical equipment for the three and six months ended June 30, 2013 was $1.3 million and $2.4 million, respectively, compared to $1.3 million and $2.6 million, respectively, for the same prior year periods. This was recorded in cost of revenues – pump depreciation and disposals.

Depreciation expense for property and equipment for the three months and six months ended June 30, 2013 was $0.1 million and $0.2 million, respectively, compared to $0.1 million and $0.3 million, respectively, for the same prior year periods. This expense was recorded in general and administrative expenses.

Medical equipment held for sale or rental contains approximately $0.5 million of pre-owned equipment received from a financial institution with such equipment coming 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 shown 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.

3. Goodwill and Intangible Assets

As of June 30, 2012, the goodwill balance was fully impaired with accumulated impairment charges of $64.1 million.

Identifiable Intangible Assets

The carrying amount and accumulated amortization of intangible assets as of June 30, 2013 and December 31, 2012 are as follows (in thousands):

Amortization expense for the three and six months ended June 30, 2013 was $0.7 million and $1.3 million, respectively, compared to $0.7 million and $1.4 million, respectively, for the same prior year periods. Expected annual amortization expense for intangible assets recorded as of June 30, 2013, is as follows (in thousands):

4. Derivative Financial Instruments

The Company used derivative instruments to manage interest rate risk and had previously designated an interest rate swap as a cash flow hedge of interest expense related to variable-rate long-term debt. To the extent this hedging relationship was effective; changes in the fair value of the interest rate swap were recorded in Accumulated Other Comprehensive Loss (“AOCL”). Amounts were reclassified from AOCL to interest expense in the period when the hedged forecasted transaction affected earnings. The Company terminated this interest rate swap in December 2012 and had no outstanding derivative contracts as of December 31, 2012 or June 30, 2013.

As of June 30, 2012, the Company had a single interest rate swap liability outstanding with a fair market value of $0.2 million, classified in Derivative Liabilities. This swap had a notional value at June 30, 2012 of $14.1 million. The Company measured the fair value of its interest rate swap using Level 2 fair value measurement inputs which are observable in the market. There were no reclassifications among fair value measurement levels during the period ended June 30, 2012.

Table of Contents

During the three and six month periods ended June 30, 2012, changes in the fair value of the derivative and reclassifications from AOCL to earnings were insignificant.

5. Debt

On November 30, 2012, the Company entered into a credit facility with Wells Fargo as Administrative Agent and PennantPark as Lenders. The facility consisted 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, all of which mature on November 30, 2016, collectively (the “Credit Facility”). Interest on the term loans 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 June 30, 2013, interest was payable at the Wells Fargo prime rate plus 6.25%, which equaled 9.50%.

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 $6.4 million and $6.5 million, respectively, outstanding amounts on the Revolver included $1.2 million and $1.8 million and a reserve amount of $0.1 million on a letter of credit at June 30, 2013, leaving approximately $5.1 million and $4.7 million available under the revolving Credit Facility as of June 30, 2013 and December 31, 2012, 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 June 30, 2013, 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 June 30, 2013 as follows (in thousands):

The following is a breakdown of the Company’s current and long-term debt as of June 30, 2013 and December 31, 2012 (in thousands):

6. Income Taxes

Income tax benefit was $0.1 million for both the three and six month periods ended June 30, 2013 compared to $0.4 million and $0.6 million, respectively, of tax benefit for the same prior year periods. In computing its income tax provision, the Company estimates its effective income tax rate for the full year and applies that rate to income earned through the reporting period.

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. A significant piece of objective negative evidence evaluated was the cumulative loss incurred over the three-year period ended June 30, 2013. After adjusting the historical losses for non-recurring items, including the goodwill impairment, legal costs pertaining to events related to the “Concerned Stockholder Group” (as described in our 2012 Form 10-K) and severance agreements, sufficient earnings history exists to support the realization of the deferred tax assets. This evidenced ability to generate sufficient taxable income is the basis for the Company’s assessment that the deferred tax assets are more likely than not to be realized.

7. Related Party Transactions

During the three and six months ended June 30, 2013 and 2012, the Company purchased pumps from Adepto Medical, a company that is controlled by a family member of Mr. Tom Creal, an Executive Vice-President of the Company. Total purchases during each of the three months and six months ended June 30, 2013 and 2012 were less than $0.1 million, respectively. Outstanding payables associated with the purchases were insignificant as of June 30, 2013 and December 31, 2012. The Company also sold pumps to Adepto. Total sales during the three months and six months ended June 30, 2013 and 2012 were less than $0.1 million. Outstanding receivables associated with the sales were less than $0.1 million as of June 30, 2013 and December 31, 2012.

The Company also leases buildings from a company partially owned by Thomas Creal. Rent is paid monthly and totals approximately $0.1 million annually.

8. Commitments and Contingencies

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. In the normal course of business, the Company has insurance policies with independent insurance carriers to minimize our risk of potential losses. 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 position, results of operations or cash flows.

9. Earnings Per Share

Basic income (loss) per share is computed by dividing net income (loss) by the weighted average number of common shares outstanding during the period. Diluted income (loss) 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 (loss) per share computations:

For the three and six months ended June 30, 2013, vested stock options of 1.2 million and 1.1 million, respectively, were not included in the calculation because they would have an anti-dilutive effect. For the same prior year periods, 1.4 million in stock options and 0.7 million in unvested restricted shares, respectively, were not included in the calculation as they would have had an anti-dilutive effect.

During the second quarter of 2012, per the terms of a consulting agreement with a former CEO, the Company terminated 2.0 million shares of common stock potentially issuable under such agreement. Under the consulting agreement, Mr. McDevitt received a consulting fee of $1.0 million, paid in shares of the Company’s common stock. Shares issued to Mr. McDevitt were issued from the Company’s 2007 Stock Incentive Plan, as amended (the “Plan”), valued at the average closing price of a share on the NYSE-MKT on the five trading days preceding the date of such issuance and totaled 0.5 million shares. In addition, the potentially issuable shares of 2.0 million were not part of Company’s 2007 Stock Plan. As these 2.0 million shares were forfeited before the requisite service period was rendered, previously recognized compensation expense of $1.3 million was reversed and recorded as a reduction of general and administrative expense during the three months ended June 30, 2012.

10. Subsequent events

On July 1, 2013, the Company entered into an employment agreement with Jonathan P. Foster, pursuant to which Mr. Foster would continue, on a permanent basis, his service as the Company’s Chief Financial Officer effective September 1, 2013. As previously disclosed, Mr. Foster has been serving as Chief Financial Officer since March 16, 2012 under a Consulting Agreement, as amended. For additional information, refer to the Company’s Current Report on Form 8-K filed with the SEC on July 8, 2013.

On July 18, 2013, the Special Committee considered the Morris Letter and issued a written response (the “Special Committee Response”). The Special Committee is comprised of the three independent members of the Board, Messrs. David Dreyer, Joseph Whitters and Wayne Yetter, and was formed on May 14, 2013 to review and be responsible for such matters. For additional information, refer to the Company’s Current Report on Form 8-K filed with the SEC on July 19, 2013.

On July 31, 2013, the Board issued an Open Letter to Shareholders. In this letter, the Board announced the following: 1) The Special Committee, after long and careful deliberation and in the best interest of all shareholders, terminated the consideration of a potential sale of the Company; 2) Following thorough discussions with the Special Committee through the Company’s investment banking firm, Houlihan Lokey, Mr. Morris and his potential financing partners did not accept the offer made by the Special Committee in its Special Committee Response; 3) As such, the Board unanimously consented to disband the Special Committee; 4) Effective immediately, Wayne Yetter, while remaining an independent Board member, stepped down as Chairman of the Board and Ryan Morris resumed his position as Executive Chairman. For additional information, refer to the Company’s Current Report on Form 8-K filed with the SEC on July 31, 2013.

InfuSystem Holdings, Inc. Results of Operations for the three and six months ended June 30, 2013 compared to the three and six months ended June 30, 2012

Revenues

Our revenue for the quarter ended June 30, 2013 was $14.7 million, a 4% increase, compared to $14.1 million for the quarter ended June 30, 2012. This increase was primarily driven by a 5% increase in rental revenue compared to the same period in the prior year. For the six months ended June 30, 2013, revenue was $29.4 million compared to $28.4 million for the same period ended June 30, 2012, a 3% increase over prior year. Again, this increase was primarily driven by a 5% increase in rental revenue compared to the same period in the prior year. Sales revenue was down 5% from prior year for the second quarter and down approximately 9% from prior year year-to-date. Management is focused on reversing this trend.

The increase in rental revenues is primarily related to the addition of larger customers, increased penetration into our existing customer accounts, the increase in the colorectal cancer and other cancer patients treated with the Company’s services and the continuation of the revision by a major group of third party payors in their claims processing guidelines. Additionally, since June 30, 2012, the Company has added another eleven plans under contract, the vast majority of which will positively impact revenue. Such strengths are being offset, by a one-time delay in the billings caused by the requirement by certain payors of additional paperwork in the first quarter of 2013 and an increase in unbilled revenue since December 31, 2012. Revenues in the second quarter were impacted significantly due to a delay in processing paperwork both in the field and in-house in the last month of the quarter. Corrections and a reduction in pending billings are expected by year-end 2013. Also during the second quarter of 2013, the Company felt the impact of the sequestration order approved by the President of United States on March 1, 2013, which effects Medicare payments, reducing revenue during the quarter by less than $0.1 million. In the absence of any bipartisan agreement in the federal government with respect to the sequestration order generally or relief from sequestration applicable to Medicate payments, this reduction will continue.

Gross Profit

Gross profit for the three months ended June 30, 2013 was $10.3 million, consistent with the quarter ended June 30, 2012. Gross profit, as a percentage of revenues, represented 70% and 73% for the three months ended June 30, 2013 and 2012, respectively. Gross profit for the six months ended June 30, 2013 was $20.8 million compared to $20.7 million for the same period in 2012. Gross profit, as a percentage of revenues, represented 71% and 73% for the six months ended June 30, 2013 and 2012, respectively. The decrease as a percentage of revenue for both periods compared to prior year is primarily related to a decrease in rental gross margin from direct pay customers.

Provision for Doubtful Accounts

Provision for doubtful accounts for the three months ended June 30, 2013 and 2012 was $1.3 million and $0.9 million, respectively. The provision for doubtful accounts was 9% of revenues for the three months ended June 30, 2013 compared to 6% for the same period in the prior year. Provision for doubtful accounts for the six months ended June 30, 2013 and 2012 was $3.0 million and $2.1 million, respectively, an increase of 43% in 2013. This increase in the provision for doubtful accounts can be mainly attributed to a major group of third party payors that revised their claim processing guidelines at the end of 2012 that affected 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 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. As a direct result of this selection, five states have new contracts under this agreement.

Amortization of Intangible Assets

Amortization of intangible assets for the three months ended June 30, 2013 was $0.7 million, consistent with the prior year period. Amortization of intangible assets for the six months ended June 30, 2013 was $1.3 million, a 3% decrease compared to the six months ended June 30, 2012.

Selling and Marketing Expenses

During the quarter ended June 30, 2013, selling and marketing expenses was $2.5 million, consistent with the quarter ended June 30, 2012. For the six months ended June 30, 2013, selling and marketing expenses was $4.9 million, a 7% decrease, compared to $5.3 million for the same period in the prior year. The decrease in selling and marketing expenses year to date was mainly attributed to lower travel, entertainment and salaries and commissions. Selling and marketing expenses during these periods consisted of sales 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, 2013, general and administrative (“G&A”) expenses was $5.0 million, a decrease of $1.1 million, or 18%, compared to $6.1 million during the same period in 2012. The decrease for the comparable period is primarily related to additional legal, accounting and outside service fees of $1.4 million and $1.0 million of severance costs associated with the Settlement Agreement with the Concerned Stockholder Group that took place in the quarter ended June 30, 2012. Those additional costs were partially offset by the reversal of previously recognized stock compensation expense of $1.3 million, for which the requisite service was not rendered last year.

For the six months ended June 30, 2013, G&A expenses was $10.0 million compared to $12.4 million in the same prior year period, a decrease of $2.4 million, or 19%. The decrease between these periods was primarily related to prior year professional service and other costs for the Concerned Stockholder Group which totaled approximately $2.3 million; severance payments for a former CEO amounted to $1.0 million; $0.6 million was recorded during the three months ended March 31, 2012 for retention payments to key employees; and $1.3 million of previously recognized stock compensation expense was reversed due to the forfeiture and failure to meet the requisite service period. These prior year charges were offset by $0.3 million of expenses during the three months ended March 31, 2013 due primarily to fees related to the CEO search, the final severance payment made to the former CEO and one-time payments to a Board member (the “Transition Costs”).

Interest Expenses

During the quarter ended June 30, 2013, we recorded interest expense of $0.9 million compared to $0.7 million for the quarter ended June 30, 2012. For the six months ended June 30, 2013, we recorded interest expense of $1.8 million, compared to $1.3 million in the same prior year period. The increase compared to prior year periods was primarily related to higher interest rates due to our new credit agreement.

Loss on Extinguishment of Long Term Debt

During the prior year quarter ended June 30, 2012, $0.3 million of previously capitalized debt issuance costs and $0.3 million of certain payments made to secure the Fifth Amendment were recognized as a loss on extinguishment of debt.

Other Income

During the first quarter of 2013, we received $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 June 30, 2013, we recorded an income tax benefit of $0.1 million compared to a tax benefit of $0.4 million during the three months ended June 30, 2012. The decreased tax benefit was primarily due to lower pre-tax losses compared to the same period in the prior year. In addition, during the quarter ended June 30, 2013, a reversal of a tax accrual was made as a result of a transfer price study that resulted in lower than originally anticipated tax expense. For the six months ended June 30, 2013, we recorded an income tax benefit of $0.1 million compared to a tax benefit of $0.6 million for the same period in the prior year. This was due to our profitability on a year to date basis in 2013 and the aforementioned tax reversal.

Liquidity and Capital Resources

As of June 30, 2013, we had cash or cash equivalents of $0.1 million and $5.1 million of availability on the Credit Facility compared to $2.3 million of cash and cash equivalents and $4.7 million of availability on the Credit Facility at December 31, 2012.

Cash generated by operating activities for the six months ended June 30, 2013 was $2.2 million compared to $2.3 million for the six months ended June 30, 2012. Although net income is significantly improved from a year ago, increases in accounts receivable are offsetting any cash improvement at June 30, 2013 when compared to the prior year.

Cash used in investing activities for the six months ended June 30, 2013 was $0.8 million compared to $0.4 million for the six months ended June 30, 2012. The increase in cash used is primarily related to a decrease in the cash proceeds from the sale of medical equipment during 2013.

Cash used in financing activities for the six months ended June 30, 2013 was $3.6 million compared to $1.9 million used for financing activities for the six months ended June 30, 2012. This increase was primarily due to a $1.3 million net increase in principle payments and loan proceeds in addition to $0.6 million in payments to retire some older capital leases during 2013.

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 $6.4 million and $6.5 million, respectively, outstanding amounts on the Revolver included $1.2 million and $1.8 million and a reserve amount of $0.1 million on a letter of credit at June 30, 2013, leaving approximately $5.1 million and $4.7 million available under the revolving Credit Facility as of June 30, 2013 and December 31, 2012, respectively.

Correspondingly, total debt less cash (“Net Debt Position”) was $28.2 million as of June 30, 2013 compared to $30.7 million as the end of 2012, a reduction by $2.5 million.

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 June 30, 2013, 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 2012 Form 10-K.

InfuSystem Holdings, Inc. is a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and is not required to provide the information required under this item.

Disclosure Controls and Procedures

We maintain disclosure controls and procedures, (as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) that are designed to ensure that information required to be disclosed in our reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer (principal executive officer) and Chief Financial Officer (principal accounting and financial officer), as appropriate, to allow timely decisions regarding required financial disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, with a company have been detected.

As of the end of the period covered by this Quarterly Report on Form 10-Q, we carried out an evaluation, under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of June 30, 2013. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that such disclosure controls and procedures as of June 30, 2013, were not effective due to a material weakness in our internal controls related to record-keeping of minutes of the meetings of the Board of Directors and its committees, identified during the fourth quarter of 2012, as described below. Notwithstanding this material weakness, based on additional procedures performed after its discovery, management believes that the financial statements included in this report fairly present in all material respects our financial condition, results of operations, and cash flows for the periods presented.

During the preparation of our Form 10-K for 2012, our management identified a material weakness in the Company’s internal control over financial reporting relating to the timely circulation and approval of minutes of the Board of Directors and its committees and our stock-based compensation calculations for the year ended December 31, 2012. During 2012 a majority of the Company’s Board of Directors and its CEO and CFO, were replaced and, in the transition, timely approval and record-keeping of board minutes were not performed. While minutes were contemporaneously recorded, this material weakness specifically related to the circulation and finalization of approvals of such minutes. Such timely circulation and approvals would have improved the timeliness and preparation of certain accounting analyses and related stock-based compensation calculations. Our management has reassessed its process with regard to Board of Directors and related committee minutes and our stock-based compensation calculations and has taken steps to assure that adequate procedures are in place on a go forward basis to remediate this weakness.

Change in Internal Control

Other than the changes described above, we have made no changes during the six months ended June 30, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II — OTHER INFORMATION

We are not involved in any legal proceedings, the outcome of which we believe would be material to our 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 titled “Risk Factors” in Part I, Item 1A of our 2012 Form 10-K. Except as noted below, there have been no material changes from the risk factors previously disclosed in our 2011 Form 10-K.

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 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.

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. 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.

On August 16, 2012, the CMS announced the timetable for Competitive Bidding Round 1 Recompete (“RD1RC”), which includes a new product category for external infusion pumps and supplies affecting nine MSAs. As of the current schedule, any changes in reimbursement associated with RD1RC will not become effective until calendar year 2014. The Company submitted its bid in December 2012. The Company’s revenue directly associated with CMS in these MSA’s currently approximates 1% of the Company’s total annual revenue. Originally, CMS was to announce single payment amounts and begin the contracting process in the Spring of 2013. During the second quarter of 2013, this schedule, as reflected on CMS’ website, was changed from “Spring 2013” to “Summer 2013”. No further update has been provided by CMS.

By 2016, CMS is scheduled to fully implement some form of competitive bidding. The impact of this 2016 schedule and RD1RC is not easily identifiable, is unclear at this time, and could, among many factors, negatively impact the Company’s market share, negatively impact business with the Company’s customers and other payors, and significantly reduce revenue, earnings and cash flow.

On April 1, 2013, as previously disclosed by the Company in its Current Report on Form 8-K, filed with the SEC on March 19, 2013, the Company issued Eric Steen 700,000 stock options as an inducement to his employment as the Company’s CEO and pursuant to the terms of an Inducement Stock Option Agreement, by and between the Company and Mr. Steen, dated as of April 1, 2013. Of Mr. Steen’s stock options, 300,000 options have an exercise price of $1.75 and 400,000 options have an exercise price of $2.75, and all options vest over a four-year period, with 25% vesting on the first anniversary of the grant date and the remaining options vesting pro rata monthly in the thirty-six months thereafter. The options will expire on the tenth anniversary of their grant date. In the event Mr. Steen is involuntarily terminated by the Company without cause, the vesting of the options that would have otherwise vested in the twelve months following the date of termination will accelerate and become exercisable. The vesting of the options may be accelerated by the Compensation Committee, in its sole discretion.

On May 2, 2013, as previously disclosed by the Company in its Current Report on Form 8-K, filed with the SEC on April 29, 2013, the Company issued Michael McReynolds 100,000 stock options as an inducement to his employment as the Company’s Chief Information Officer and pursuant to the terms of an Inducement Stock Option Agreement, by and between the Company and Mr. McReynolds, dated as of April 29, 2013. Mr. McReynold’s options have an exercise price of $1.75 per share and vest one-third on

each of the next three (3) anniversaries of the grant date, provided that Mr. McReynolds is employed by the Company on each of these dates. In the event that Mr. McReynolds is involuntarily terminated by the Company without cause within six months of a change in control of the Company, his options will immediately accelerate and become exercisable. In the event that Mr. McReynolds is otherwise involuntarily terminated by the Company without cause, his options will vest pro rata based on the length of his service in the year of the termination of his employment.

These inducement stock options were issued outside the Company’s 2007 Stock Option Plan in connection with the offer of employment to Messrs. Steen and McReynolds. The offer and sale of inducement stock options to Messrs. Steen and McReynolds were made pursuant to the exemption from registration under Section 4(2) of the Securities Act of 1933 for transactions not involving a public offering, and regulations promulgated thereunder.
