Report of Independent Registered Public Accounting Firm

We have reviewed the accompanying condensed consolidated balance sheet of CHF Solutions, Inc. and subsidiaries as of September 30, 2017 and the condensed consolidated statements of operations and comprehensive loss for the three-month and nine-month periods ended September 30, 2017 and the condensed consolidated statement of cash flows for the nine-month period ended September 30, 2017. These interim condensed consolidated financial statements are the responsibility of the company's management.

We conducted our review in accordance with the standards of the Public Company Accounting Oversight Board (United States). A review of interim financial information consists principally of applying analytical procedures and making inquiries of persons responsible for financial and accounting matters. It is substantially less in scope than an audit conducted in accordance with the standards of the Public Company Accounting Oversight Board, the objective of which is the expression of an opinion regarding the consolidated financial statements taken as a whole. Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should be made to the accompanying interim condensed consolidated financial statements for them to be in conformity with accounting principles generally accepted in the United States of America.

Principles of Consolidation: The accompanying condensed consolidated balance sheet as of December 31, 2022, which has been derived from the consolidated audited financial statements, and the unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (U.S.(“U.S. GAAP”) (U.S. GAAP) for interim financial information and with the instructions to Form 10-Q and Article 108 of Regulation S-X.

In the opinion of management, the condensed consolidated financial statements reflect all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of the results of the Company for the periods presented. Operating results for interim periods are not necessarily indicative of results that may be expected for the year as a whole. The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and the related disclosures at the date of the consolidated financial statements and during the reporting period. Actual results could differ materially differ from these estimates.

At September 30, 2017,As of March 31, 2023, the Company had an accumulated deficit of $175$273.9 million and it expects to incur losses for the immediate future. To date, the Company has been funded by debt and equity financings, and although the Company believes that it will be able to successfully fund its operations, there can be no assurance that it will be able to do so or that it will ever operate profitably. These factors raise substantial doubt about the Company’s ability to continue as a going concern through the next twelve months.

The Company became a revenue generatingrevenue-generating company after acquiring the Aquadex Business in August 2016.  The Company expects to incur additional losses in the near-term as it grows the Aquadex Business, including investments in expanding its sales and marketing capabilities, clinical evaluations, purchasing inventory, manufacturing components, and complying with the requirements related to being a U.S. public company.  To become and remain profitable, the Company must succeed in expanding the adoption and market acceptance of the Aquadex FlexFlow.System. This will require the Company to succeed in training personnel at hospitals and in outpatient care settings, and effectively and efficiently manufacturing, marketing and distributing the Aquadex FlexFlowSystem and related components. There can be no assurance that the Company will succeed in these activities, and it may never generate revenues sufficient to achieve profitability.

See Note 3—Stockholders’ Equity for additional related disclosures. The Company maywill require additional funding in the future,to grow its Aquadex Business, which may not be available on terms favorable to the Company, or at all. The Company’s ability to continue as a going concern may be dependent on the Company’s ability to raise additional capital based on the achievement of commercial milestones. Should future capital raising be unsuccessful, the Company may not be able to continue as a going concern. On April 24, 2017, the Company closed on an underwritten public equity offering for net proceeds of approximately $8.0 million after deducting the underwriting discounts and commissions and other costs associated with the offering (see Note 4 - Equity). The Company believes it will need to raise additional funds to finance its operations in the fourth quarter of 2017 or first quarter of 2018. The Company may receive those funds from the proceeds from future warrant exercises, issuances of equity securities, or other financing transactions. No adjustments have been made relating

On March 3, 2023, we entered into a Sales Agreement with Ladenburg Thalmann & Co. Inc. (“Ladenburg”) to create an at-the-market offering program under which we may offer and sell shares having an aggregate offering price of up to $10.0 million.

However, the Company not continue asmay seek to raise additional capital to support its growth or other strategic initiatives through debt, equity or a going concern.combination thereof. There can be no assurance we will be successful in raising additional capital.


Revenue Recognition:The Company recognizes revenuesrevenue in accordance with Accounting Standards Codification, Topic 606, Revenue from product salesContracts with Customers, which the Company adopted effective January 1, 2018.  Accordingly, the Company recognizes revenue when earned. Specifically, revenue is recognized when persuasive evidenceits customers obtain control of its products or services, in an arrangement exists, delivery has occurred,amount that reflects the price is fixed or determinable,consideration that the Company expects to receive in exchange for those goods and collectability is reasonably assured.services.

The shipping terms for the Company’s revenue arrangements are FOB shipping point. During the ninethree months ended September 30, 2017,March 31, 2023, two customers accounted for 13.9%represented 14% and 10.8%, respectively,13% of net sales.  For the Company’s totalthree months ended March 31, 2022, two customers represented 14% and 10% of net sales.


Accounts Receivable:Receivable: Accounts receivable are unsecured, are recorded at net realizable value, and do not bear interest. The Company makes judgments as to its ability to collect outstanding receivables based upon significant patterns of uncollectability,collectability, historical experience, and managements’management’s evaluation of specific accounts and will provide an allowance for credit losses when collection becomes doubtful. The Company performs credit evaluations of its customers’ financial condition on an as-needed basis. Payment is generally due 30 days from the invoice date and accounts past 30 days are individually analyzed for collectability. When all collection efforts have been exhausted, the account is written off against the related allowance. To date the Company has not experienced any write-offs or significant deterioration of the aging of its accounts receivable, and therefore, no allowance for doubtful accounts was considered necessary as of September 30, 2017March 31, 2023, or December 31, 2016. At September 30, 2017,2022. As of March 31, 2023, three customers accounted for 19.3%represented 17%, 11.4%,11% and 10.4%, respectively,10% of the Company’s total accounts receivable.receivable balance.

Inventories: Inventories represent finished goods purchased from the Company’s suppliersuppliers and are recorded as the lower of cost or marketnet realizable value using the first-in-first outfirst-in, first-out method.

Intangible assets:  The Company’s intangible assets consist of customer relationships, developed technology, and trademarks and tradenames. All intangible assets recognized by Overhead is allocated to manufactured finished goods inventory based on the Company result from the acquisitionnormal capacity of the Aquadex Business. All intangible assetsCompany’s production facilities. Abnormal amounts of overhead, if any, are estimated to have a useful life of 7 years.  The Company reviews its definite-lived intangible assets for impairment whenever events or changes in circumstances indicate that the carrying amountexpensed as incurred. Inventories consisted of the assets may not be recoverable through the estimated undiscounted future cash flows derived from such assets.  In cases where the carrying value exceeds the undiscounted cash flows, the carrying value is written down to its fair value, using a discounted cash flow analysis.  No impairments have been identified or recorded in the periods presented.following:

Goodwill:  Goodwill is the cost of an acquisition in excess of the fair value of acquired assets and liabilities and is recorded as an asset on the balance sheet. Goodwill is not subject to amortization but must be tested for impairment at least annually. This test requires the Company to determine if the implied fair value of the goodwill is less than its carrying amount.

The Company evaluates goodwill for impairment annually on November 1st of each calendar year, or to the extent events or conditions indicate a risk of possible impairment during the interim periods prior to its annual impairment test. Generally, the evaluation of goodwill for impairment involves a two-step test, although under certain circumstance an initial qualitative evaluation may be sufficient to conclude that goodwill is not impaired without conducting the quantitative test.

Step 1 involves comparing the estimated fair value of each respective reporting unit to its carrying value, including goodwill. If the estimated fair value exceeds the carrying value, the reporting unit’s goodwill is not considered impaired. If the carrying value exceeds the estimated fair value, step 2 must be performed to determine whether goodwill is impaired and, if so, the amount of the impairment. Step 2 involves calculating an implied fair value of goodwill by performing a hypothetical allocation of the estimated fair value of the reporting unit determined in step 1 to the respective tangible and intangible net assets of the reporting unit. The remaining implied goodwill is then compared to the actual carrying amount of the goodwill for the reporting unit. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment.  No impairments have been identified or recorded in the periods presented.

Contingent considerationLoss per share: In connection with the Company’s purchase of Aquadex, the Company has an obligation to pay additional consideration that is contingent upon the occurrence of certain future events.  Contingent consideration was recognized at the acquisition date at the estimated fair value of the contingent milestone payments.  The fair value of the contingent consideration is remeasured to its estimated fair value at the end of each reporting period, with changes recorded to earnings.

Common stock warrant liability:  The Company recorded its common stock warrant liability at fair value at the date of issuance using primarily a Monte Carlo valuation model (see Note 6 - Fair Value of Financial Instruments).  The fair value is remeasured to its estimated fair value at the end of each reporting period with changes recorded to earnings.

Earnings per share:Basic earningsloss per share is computed based on the net loss allocable to common stockholders for each period divided by the weighted average number of common shares outstanding. The net loss allocable to common stockholdersSee Note 3 – Stockholders’ Equity below for the nine months ended September 30, 2017, reflects a $1.0 million increase for the net deemed dividend to preferred stockholders provided in connection with the close of the public offering of Series E Convertible Preferred Stock in April of 2017 (see Note 4 - Equity), representing the intrinsic value of the shares at the time of issuance. In addition, the net loss allocable to common stockholders for the nine months ended September 30, 2017, reflects a $1.8 million increase for the net deemed dividend to preferred stockholders provided in connection with the shareholder approval of the Series C and D Convertible Preferred Stock offering in January of 2017 (see Note 4 - Equity), representing the intrinsic value of the shares at the time of issuance. additional disclosures.

Diluted earnings per share is computed based on the net loss allocable to common stockholders for each period divided by the weighted average number of common shares outstanding, increased by the number of additional shares that would have been outstanding had the potentially dilutive common shares been issued, and reduced by the number of shares the Company could have repurchased from the proceeds from issuance of the potentially dilutive shares. Potentially dilutive shares of common stock include shares underlying outstanding convertible preferred stock, warrants, stock options and other stock-based awards granted under stock-based compensation plans. These potentially dilutive shares were excluded from the computation

Subsequent events: The Company evaluates events through the Financial Accounting Standards Board (FASB), issued amended stock compensation guidancedate the consolidated financial statements are filed for events requiring adjustment to simplify various aspects of employee share-based payments accounting and presentationor disclosure in the financial statements. The new guidance requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled, allows an employer to repurchase more of an employee’s shares than previously allowed for tax withholding purposes without triggering liability accounting, allows a company to make a policy election to account for forfeitures as they occur, and eliminates the requirement that excess tax benefits be realized before companies can recognize them. The new guidance also requires excess tax benefits and tax shortfalls to be presented on the cash flow statement as an operating activity rather than as a financing activity, and clarifies that cash paid to a tax authority when shares are withheld to satisfy its statutory income tax withholding obligation are to be presented as a financing activity. The standard was effective for the Company’s interim and annual periods beginning after January 1, 2017. The Company adopted the guidance in the current year. The adoption of this standard did not have a material impact to the Company’s consolidated financial statements.


Note 2 – Revenue Recognition

Net Sales: The Company sells its products in the United States primarily through a direct salesforce. Customers who purchase the Company’s products include hospitals and clinics throughout the United States.  In May 2014, August 2015, March 2016, April 2016countries outside the United States, the Company sells its products through a limited number of specialty healthcare distributors in Austria, Brazil, Colombia, The Czech Republic, Germany, Greece, Hong Kong, India, Israel, Italy, Panama, Romania, Singapore, Slovakia, Spain, Switzerland, Thailand, United Arab Emirates, and May 2016, the FASB issued amended revenue recognition guidanceUnited Kingdom. These distributors resell the Company’s products to clarifyhospitals and clinics in their respective geographies.

Revenue from product sales is recognized when the principles for recognizing revenue from contracts with customers.customer or distributor obtains control of the product, which occurs at a point in time, most frequently upon shipment of the product or receipt of the product, depending on shipment terms. The guidance requires an entity to recognize revenue to depictCompany’s standard shipping terms are FOB shipping point unless the transfer of goods or services to customers in an amountcustomer requests that reflects the consideration to which an entity expects to be entitled in exchange for those goods or services. The guidance also requires expanded disclosures relatingcontrol and title to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract.   The standard allows the Company to transition to the new model using either a full or modified retrospective approach. This guidance will be effective for the Company’s interim and annual periods beginning January 1, 2018. Although the assessmentinventory transfer upon delivery.

Revenue is not complete, the Company believes that this standard will not have a material impact on its business practices, financial condition, results of operations and disclosures. The Company expects to complete the assessment in the fourth quarter of 2017.
In November 2015, the FASB issued amended guidance concerning the classification of deferred taxes on the balance sheet to require that deferred tax assets and deferred tax liabilities be presented as noncurrent in a classified balance sheet. The amendment was effective for our annual and interim reporting periods beginning January 1, 2017, with early adoption permitted. The Company adopted this standard in the first quarter of 2017 with no impact on the Company’s consolidated financial statements as all net deferred tax assets are fully reserved.

In February 2016, the FASB issued updated guidance to improve financial reporting about leasing transactions. This guidance will require organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. This guidance is effective for the Company’s annual and quarterly reporting periods beginning January 1, 2019.  The Company is evaluating the impact that the adoption of this standard will have on its consolidated financial statements and disclosures.

In January 2017, the FASB issued amended guidance to simplify the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test. A goodwill impairment will now be measured as the amount byof consideration we expect to receive, adjusted for any applicable estimates of variable consideration and other factors affecting the transaction price, which is based on the invoiced price, in exchange for transferring products. All revenue is recognized when the Company satisfies its performance obligations under the contract. The majority of the Company’s contracts have a reporting unit’s carryingsingle performance obligation and are short term in nature. The Company has entered into extended service plans with customers whose related revenue is recognized over time. This revenue represents less than 1% of net sales for the three months ended March 31, 2023, and 2022. The unfulfilled performance obligations related to these extended service plans are included in deferred revenue, which is included in other current liabilities on the consolidated balance sheets. The majority of the deferred revenue is expected to be recognized within one year.

Sales taxes and value exceedsadded taxes in foreign jurisdictions that are collected from customers and remitted to governmental authorities are accounted for on a net basis and therefore are excluded from net sales. Revenue includes shipment and handling fees charged to customers. Shipping and handling costs associated with outbound freight after control over a product has transferred to a customer are accounted for as a fulfillment cost and are included in cost of goods sold.

Product Returns: The Company offers customers a limited right of return for its fair value, limited toproducts in case of non-conformity or performance issues. The Company estimates the amount of goodwill allocated to that reporting unit. This guidance is to be applied on a prospective basis effective for the Company’s interim and annual periods beginning after January 1, 2020, with early adoption permitted for any impairment tests performed after January 1, 2017. The Company is currently evaluating the effect of this update on its consolidated financial statements.

Note 2 – Aquadex Acquisition

On August 5, 2016, the Company completed the acquisition of certain assets used in the production and sale of the Aquadex product line from Baxter. The acquisition of these assets meets the criteria for the purchase of a business, and has been accounted for in accordance with Accounting Standards Codification (ASC) 805, Business Combinations, with identifiable assets acquired and liabilities assumed recorded at their estimated fair values on the acquisition date. A valuation of the assets and liabilities from the business acquisition was performed utilizing cost, income and market approaches resulting in $5.1 million allocated to identifiable net assets.

In connection with the acquisition of the Aquadex Business, the Company entered into a manufacturing and supply agreement with Baxter whereby Baxter agreed to manufacture and supply all of the Company’s finished goods for a period of up to 18 months from the close of the transaction. The Company completed the acquisition in order to strengthen its presence in the heart failure market.

Purchase Consideration: Total purchase consideration for the Aquadex Business was as follows:

(in thousands)   
Cash consideration $4,000 
Common stock consideration  950 
Fair value of contingent consideration  126 
Total purchase consideration $5,076 

-
Common Stock Consideration: The common stock consideration consisted of 1,666 shares of the Company’s common stock, worth $0.95 million based on the closing market value of $570.00 per share on August 5, 2016.

-
Contingent Consideration: In connection with the acquisition of the Aquadex product line, the Company agreed to pay Baxter 40% of any proceeds in excess of $4.0 million related to the sale or disposal of the Aquadex assets within three years of the close of the transaction. The fair value of this contingent consideration was calculated based on the estimated likelihood of occurrence of this event in the timeframe provided by the agreement.

Purchase price consideration does not include expenses of $0.9 million for accounting, audit, legal, and valuation services that were incurred as part of the transaction and were expensed as incurred.

The acquisition was recorded by recognizing the assets acquired at their estimated fair value at the acquisition date. The excess of the cost of the acquisition over the fair value of the assets acquired was recorded as goodwill. The fair values were based on management’s analysis, including work performed by third-party valuation specialists. The following presents the amounts recognized for the assets acquired on August 5, 2016 (in thousands):
Capital lease asset $307 
Intangible assets  4,580 
Total identifiable assets acquired  4,887 
Goodwill  189 
Total purchase consideration $5,076 
The goodwill is primarily attributable to new and/or future customer relationships that were not acquired in the transaction. The fair value of the capital lease asset utilized a combination of the cost and market approaches, depending on the characteristics of the asset classification. Of the $4.6 million of acquired intangible assets, $3.1 million was assigned to customer relationships, $1.1 million was assigned to developed technology, and $0.4 million was assigned to trademarks and tradename. All intangible assets are estimated to have a useful life of 7 years.

Pro Forma Condensed Combined Financial Information (Unaudited)
The following unaudited pro forma combined financial information summarizes the results of operations for three months and nine months ended September 30, 2016 as if the acquisition of Aquadex had been completed on of January 1, 2016. Pro forma information reflects adjustments that are expected to have a continuing impact on our results of operations and are directly attributable to the acquisition. The unaudited pro forma results include adjustments to reflect, among other things, direct transaction costs relating to the acquisition, the difference in intangible asset amortization to be incurred based on the preliminary values of each identifiable intangible asset, and the difference in depreciation expense to be incurred based on preliminary value of the capital lease asset. The pro forma amounts do not purport to be indicative of the results that would have actually been obtained if the acquisition had occurred as of January 1, 2016 orsales that may be obtainedreturned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized.  The Company currently estimates product return liabilities using available industry data and its own historical sales and returns information.  The Company has not received any returns to date and believes that future and doreturns of its products will be minimal. Therefore, revenue recognized is not reflect future synergies, integration costs, or other such costs or savings.currently impacted by variable consideration related to product returns.

This reverse stock split did not change the par value of the Company’s common stock or the number of common or preferred shares authorized by the Company’s Fourth Amended and Restated Certificate of Incorporation, as amended. All share and per-share amounts have been retroactively adjusted to reflect the reverse stock splits for all periods presented.

On January 4, 2023, stockholder approval was secured by the Company for the exercisability of the common stock warrants. Upon stockholder approval, the warrants were determined to be equity-classified warrants. Concurrent with stockholder approval, the warrants were marked to market, then reclassified to the equity section of the balance sheet.

These warrants were subject to a reduction of the exercise price if the Company subsequently issued common stock or equivalents at an effective price less than the current exercise price of such warrants.

Warrant Exercise Agreement:  On February 15, 2017, the Company entered into a letter agreement with the institutional investors that held the majority of its outstanding warrants (the ‘‘Original Warrants’’), to incent the cash exerciseMay 30, 2024. None of these warrants on or beforehad vested as of March 31, 2017. In exchange for any such exercise, the Company agreed to provide the investors a replacement warrant (the ‘‘Replacement Warrants’’) to purchase the same number of shares of common stock as were issued upon exercise of the Original Warrants, with an exercise price equal to the consolidated closing bid price of its common stock on the date of issuance. The Replacement Warrants were issued in the same form as the Original Warrants except the exercise prices are not subject to reduction for subsequent equity issuances and the Replacement Warrants do not allow the investor to demand that the Company purchase the Replacement Warrants in the event of a fundamental transaction involving the Company. In connection with this agreement, between February and March 2017, the investors exercised all of the Original Warrants for gross cash proceeds to the Company of $2.0 million, and the Company issued 43,396 Replacement Warrants with exercise prices ranging from $34.6 per share to $99.8 per share.2023.


The Company entered into the letter agreement with the investors to incent the exercise of the Original Warrants in order to receive the cash proceeds from the exercise of the Original Warrants and because the exercise of the Original Warrants would allow the Company to remove the warrant liability from its balance sheet and avoid future fair value adjustments and associated volatility in its consolidated financial statements, as the Replacement Warrants are not accounted for as liabilities based on their terms. As of September 30, 2017, there were no Original Warrants outstanding and all Replacement Warrants under the letter agreement had been issued.

Placement Agent Warrant: In connection with the issuance of the Series B, C and D Convertible Preferred Stock, the Company issued warrants to the placement agent to purchase an aggregate of 2,602 shares of common at exercise prices ranging from $127.6 per share to $810.0 per share. These warrants were issued at no additional cost, were exercisable immediately and expire five years from the closing of the offerings. These warrants do not contain repricing provisions.

Warrant Valuation: Both the Original Warrants and placement agent warrants were accounted for as liabilities and were recorded at fair value on the date of issuance. These warrants must be measured and recorded at fair value for each subsequent reporting period that the warrants remain outstanding, and any changes in fair value must be recognized in the consolidated statement of operations and comprehensive loss. In connection with the warrant exchange agreement described above, the Company remeasured each Original Warrant as of the date of exercise and recorded $1.4 million for the change in fair value of these warrants as an unrealized gain in the accompanying consolidated statement of operations and comprehensive loss for the nine months ended September 30, 2017. Warrant liability totaled $1.8 million as of December 31, 2016, and $6,000 as of September 30, 2017.

The Replacement Warrants were valued at $0.5 million using the Black Scholes valuation model with the following assumptions: an expected dividend yield of 0%, expected stock price volatility of 49.65%-50.38%, risk-free interest rates of 1.95%-1.97% and an expected life of 5 years. The warrants have a five-year life and were fully vested at the date of grant. The terms of the Replacement Warrants do not require them to be accounted for as liabilities and are therefore recorded in equity.  As in incentive to early exercise the Original Warrants, the fair value provided to investors through the Replacement Warrants exceeded the fair value of the Original Warrants that was relinquished by the warrant holders by approximately $0.1 million, which has been reflected as an expense in the consolidated statement of operations and comprehensive loss for the nine months ended September 30, 2017.
Note 54 - Stock-Based Compensation


Under the fair value recognition provisions of U.S. GAAP for accounting for stock-based compensation, the Company measures stock-based compensation expense at the grant date based on the fair value of the award and recognizes the compensation expense over the requisite service period, which is generally the vesting period.

Note 6 - 5—Fair Value of Financial Instruments


The Company’s financial instruments consist of cash and cash equivalents, warrants,marketable securities, and contingent consideration.warrants.


Pursuant to the requirements of ASCAccounting Standards Codification (“ASC”) Topic 820 “Fair“Fair Value Measurement,” the Company’s financial assets and liabilities measured at fair value on a recurring basis are classified and disclosed in one of the following three categories:


·
Level 1 - Financial instruments with unadjusted quoted prices listed on active market exchanges.


·
Level 2 - Financial instruments lacking unadjusted, quoted prices from active market exchanges, including over the counterover-the-counter traded financial instruments. The prices for the financial instruments are determined using prices for recently traded financial instruments with similar underlying terms as well as directly or indirectly observable inputs, such as interest rates and yield curves that are observable at commonly quoted intervals.



·
Level 3 - Financial instruments that are not actively traded on a market exchange. This category includes situations where there is little, if any, market activity for the financial instrument. The prices are determined using significant unobservable inputs or valuation techniques.


All cash equivalents and marketable securities are considered Level 1 measurements for all periods presented.

The available-for-sale marketable securities primarily consist of investment-grade, U.S. dollar-denominated fixed and floating-rate debt, measured at fair value on a recurring basis.

The fair value of the Company’s common stock warrant liability related to the Original Warrantsinvestor warrants issued in the October 2022 public offering was calculated using a Monte Carlo valuation model and was classified as Level 3 in the fair value hierarchy. The common stock warrants issued July 26, 2016 had a fair value of $226,000 on December 31, 2016 and $46,000 as of their dates of exercise. The common stock warrants issued November 3, 2016 had a fair value of $1.5 million on December 31, 2016 and $0.4 million as of their exercise dates. The common stock warrants issued January 12, 2017 had a fair value $72,000 on the date of issuance and $18,000 as of the date of exercise. All Original Warrants were classified as a warrant liability and were exercised during the nine months ended September 30, 2017.


The fair valuefollowing is a roll-forward of the Company’s common stock warrant liability related to the placement agent warrants is calculated using a Black Scholes valuation model and is classified as Level 3 in the fair value hierarchy.

The fair value of the Company's contingent consideration, as described in Note 2, was initially measured based on the consideration expected to be transferred (probability-weighted), discounted back to present value, and it is considered a Level 3 instrument. The discount rate used was determined at the time of measurement in accordance with accepted valuation methods. The Company measures the liability on a recurring basis using Level 3 inputs including probabilities of payment and projected payment dates. Changes to any of the inputs may result in significantly higher or lower fair value measurements. There were no changes in the fair value of the contingent consideration subsequent to the initial measurement.

All cash equivalents are considered Level 1 measurements for all periods presented. The Company does not have any financial instruments classified as Level 2 or any other classified as Level 3 and there were no movements between these categories during the periods ended September 30, 2017 and December 31, 2016. The Company believes that the carrying amounts of all remaining financial instruments approximate their fair value due to their relatively short maturities.warrants:

Note 76 – Income Taxes


The Company provides for a valuation allowance when it is more likely than not that it will not realize a portion of the netits deferred tax assets. The Company has established a full valuation allowance for its U.S. and foreign deferred tax assets due to the uncertainty that enough taxable income will be generated in those taxing jurisdictions to utilize the assets. Therefore, the Company has not reflected any benefit of such net deferred tax assets in the accompanying condensed consolidated financial statements.

During 2017, the Company experienced an ownership change as defined in Section 382 of the Internal Revenue Code which will limit the ability to utilize the Company’s net operating losses (NOLs). The Company may have experienced additional ownership changes in earlier years further limiting the NOL carry-forwards that may be utilized.  The Company has not yet completed a formal Section 382 analysis.  The general limitation rules allow the Company to utilize its NOLs subject to an annual limitation that is determined by multiplying the federal long-term tax-exempt rate by the Company’s value immediately before the ownership change.

As of September 30, 2017,March 31, 2023, there were no material changes to what the Company disclosed regarding tax uncertainties or penalties in its Annual Report on Form 10-K for the year ended December 31, 2016.2022.

Impact of COVID-19 Pandemic

During 2017,2021 and 2022, we were subject to challenging social and economic conditions created as a result of the outbreak of the novel strain of coronavirus, SARS-CoV-2. The resulting impact of the COVID-19 pandemic created disruptions in our boardoperations resulting from rapid and evolving changes implemented to keep our customers, their patients, and our employees safe. These changes included restrictions on hospital access imposed on our field employees by customers dealing on the front lines of directorsCOVID-19 and stockholders approved two reverse stock splits. Neither reverse stock split changedmanaging the par valuespread of the virus, changes to work practices by requiring employees to work remotely, and increased protocols to ensure the safety of those employees that remained on site. The ongoing impact of the COVID-19 outbreak on our common stockoperational and financial performance has diminished, but we may still experience downstream effects that will depend on certain future developments, including the ongoing impact on our customers, hospital access restrictions imposed on our field employees, and effects on our vendors, all of which remain uncertain and cannot be predicted.

Several hospitals in the U.S. initially included the Aquadex System in their treatment protocol for fluid management of COVID-19, especially when dialysis equipment and staff were limited, but treatment regimens subsequently evolved so that the need to restore fluid balance became less prevalent. However, we also experienced changes to our sales practices due to restrictions on hospital access and believe that revenue in other areas was negatively impacted by these restrictions. In addition, the disruption created by COVID-19 created significant uncertainty about our ability to access the capital markets in future periods. As of the filing date of this Form 10-Q, while we are not currently experiencing direct effects of the COVID-19 pandemic, the extent to which COVID-19 or a future pandemic outbreak may impact our financial condition or results of operations or guidance is uncertain and cannot be reasonably estimated but could be material and last for an extended period of time. The effect of the numberCOVID-19 pandemic may not be fully reflected in our results of common or preferred shares authorized by the Company’s Fourth Amendedoperations and Restated Certificate of Incorporation.  The first reverse stock split was a 1-for-30 reverse split ofoverall financial performance until future periods. See Part 1, Item 1-A “Risk Factors”in our outstanding common stock that became effective after trading on January 12, 2017.   The second reverse stock split was a 1-for-20 reverse split of our outstanding common stock that became effective after trading on October 12, 2017.  All share and per share amounts in this QuarterlyAnnual Report on Form 10-Q10-K for the three and nine monthsyear ended September 30, 2017 and 2016, including the consolidated financial statements and notes thereto, have been retroactively adjusted to reflect the reverse stock splits for all periods presented.December 31, 2022.

Warrant Exercise Agreement

On February 15, 2017, we entered into a letter agreement with the institutional investors that held the majority of our outstanding warrants, to incent the cash exercise of these warrants on or before March 31, 2017. In exchange for any such exercise, we agreed to provide the Investors a replacement warrant (the “Replacement Warrants”) to purchase the same number of shares of common stock as were issued upon exercise of the exercised warrants, with an exercise price equal to the consolidated closing bid price of our common stock on the date of issuance. The Replacement Warrants are in the same form as the exercised warrants except the exercise prices are not subject to reduction for subsequent equity issuances and the Replacement Warrants do not allow the investor to demand that we purchase the Replacement Warrants in the event of a fundamental transaction involving the Company. In connection with this agreement, the investors exercised all of the Original Warrants for gross cash proceeds to us of $2.0 million, and we issued 43,396 Replacement Warrants with exercise prices ranging from $34.6 per share to $99.8 per share.

We entered into the letter agreement with the investors to incent the exercise of the Original Warrants in order to receive the cash proceeds from the exercise of the Original Warrants and because the exercise of the Original Warrants would allow us to remove the warrant liability from our balance sheet and avoid future fair value adjustments and associated volatility in our consolidated financial statements. As of September 30, 2017, we had no Original Warrants outstanding and we had issued all Replacement Warrants under the letter agreement.

Public Offering

On April 24, 2017, we closed on an underwritten public offering of 140,000 shares of common stock, 6,400 shares of Series E Convertible Preferred Stock and warrants to purchase 460,000 shares of common stock, which includes the full exercise of the underwriter’s over-allotment option to purchase additional shares and warrants, for gross proceeds of $9.2 million.  Net proceeds totaled approximately $8.0 million after deducting the underwriting discounts and commissions and other costs associated with the offering.

On September 21, 2016, we received notice from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that the Staff had determined to delist our securities from The Nasdaq Capital Market due to our then continued non-compliance with the minimum bid price requirement.  We timely requested a hearing before the Nasdaq Hearings Panel (the “Panel”), which occurred on November 10, 2016.  On November 11, 2016, we received notice from the Staff that we no longer satisfied Nasdaq Listing Rule 5550(b) insofar as we did not expect to report stockholders’ equity of at least $2.5 million upon the filing of our Quarterly Report on Form 10-Q for the quarter ended March 31, 2017 and that the deficiency could serve as an additional basis for the delisting of the Company’s common stock from The Nasdaq Capital Market.  On November 21, 2016, Nasdaq informed us that the Panel had granted us continued listing on The Nasdaq Capital Market while we implemented our plan to regain compliance with the minimum bid price and minimum stockholders’ equity requirements.  The Panel granted us until January 30, 2017 to evidence a closing bid price of $1.00 or more for a minimum of ten prior consecutive trading days. After implementing the reverse stock split described above, we received confirmation from Nasdaq on February 9, 2017 that we regained compliance with the minimum bid price rule.  The Panel had granted us until March 20, 2017 to evidence compliance with the $2.5 million stockholder’s equity requirement. On March 28, 2017, we announced that the Panel had granted us an extension through May 10, 2017 to evidence compliance with the minimum shareholder’s equity requirement.  On May 4, 2017, we were formally notified by Nasdaq that we had regained compliance with the minimum stockholders’ equity requirement and we were in compliance with all other applicable requirements for listing on The Nasdaq Capital Market.

On June 1, 2017, we received a subsequent notification from Nasdaq informing us that we were no longer in compliance with the minimum bid price requirement, as the bid price of our shares of common stock (“Common Stock”) closed below the minimum $1.00 per share for the 30 consecutive business days prior to the date of the notice. Nasdaq also notified us that we were provided 180 calendar days, or until November 28, 2017, to regain compliance with the minimum bid price requirement. We effected a 1-for-20 reverse split of our outstanding common stock that became effective after trading on October 12, 2017, After implementing the reverse stock split described above, we received confirmation from Nasdaq on October 27, 2017, that we had regained compliance with the minimum bid price rule and the listing matter was closed.


CRITICAL ACCOUNTING POLICIES AND ESTIMATES


We have adopted various accounting policies to prepare the condensed consolidated financial statements in accordance with accounting principles generally accepted in the United States. (U.S. GAAP)States (“U.S. GAAP”). Our most significant accounting policies are disclosed in Note 1 to the consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016.2022.


The preparation of the condensed consolidated financial statements, in conformity with U.S. GAAP, requires us to make estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes. Our estimates and assumptions, including those related to stock-based compensation, valuation of equity and debt securities, and income tax reserves are updated as appropriate, which in most cases is quarterly. We base our estimates on historical experience, valuations, or various assumptions that are believed to be reasonable under the circumstances. Other than new estimates made in connection with the valuation of our warrant liability, thereThere have been no material changes to our critical accounting policies and estimates from the information provided in Part II, Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations included in our Annual Report on Form 10-K for the year ended December 31, 2016.2022.


Revenue Recognition: Recognition: We recognize revenue in accordance with ASC Topic 606, Revenue from product salesContracts with Customers. Accordingly, we recognize revenue when earned. Specifically, revenue is recognized when persuasive evidenceour customers obtain control of their products or services, in an arrangement exists, delivery has occurred,amount that reflects the price is fixed or determinable, and collectability is reasonably assured. Revenue is not recognized until title and risk of loss have transferred to the customer. The shipping terms for our revenue arrangements are FOB shipping point.

Accounts Receivable:  Our accounts receivable have termsconsideration that require payment in 30 days.  We did not establish an allowance for doubtful accounts at September 30, 2017 as we have not experienced any write offs or a deterioration in the aging of our receivables to date and do not expect to experiencereceive in the future.

Inventories:  Inventories represent finishedexchange for those goods purchased from our supplier and are recorded as the lower of cost or market using the first-in-first out method.

Intangible assets:  Our intangible assets consist of $3.1 million for customer relationships, $1.1 million for developed technology, and $0.4 million for trademarks and tradenames. All intangible assets are estimated to have a useful life of 7 years.  We review our definite-lived intangible assets for impairment when impairment indicators exist.  When impairment indicators exist, we determine if the carrying value of the intangible assets exceeds the related undiscounted cash flows.  In cases where the carrying value exceeds the undiscounted cash flows, the carrying value is written down to its fair value, generally using a discounted cash flow analysis.  No impairments have been identified or recorded in the periods presented.
Goodwill:  Goodwill is the cost of an acquisition in excess of the fair value of acquired assets and liabilities and is recorded as an asset on our balance sheet. Goodwill is not subject to amortization but must be tested for impairment at least annually. This test requires us to assign goodwill to an appropriate reporting unit and to determine if the implied fair value of the reporting unit’s goodwill is less than its carrying amount.

We evaluate goodwill for impairment annually on November 1st of each calendar year, or to the extent events or conditions indicate a risk of possible impairment during the interim periods prior to our annual impairment test. Generally, the evaluation of goodwill for impairment involves a two-step test, although under certain circumstance an initial qualitative evaluation may be sufficient to conclude that goodwill is not impaired without conducting the quantitative test.

Step 1 involves comparing the estimated fair value of each respective reporting unit to its carrying value, including goodwill. If the estimated fair value exceeds the carrying value, the reporting unit’s goodwill is not considered impaired. If the carrying value exceeds the estimated fair value, step 2 must be performed to determine whether goodwill is impaired and, if so, the amount of the impairment. Step 2 involves calculating an implied fair value of goodwill by performing a hypothetical allocation of the estimated fair value of the reporting unit determined in step 1 to the respective tangible and intangible net assets of the reporting unit. The remaining implied goodwill is then compared to the actual carrying amount of the goodwill for the reporting unit. To the extent the carrying amount of goodwill exceeds the implied goodwill, the difference is the amount of the goodwill impairment.  No impairments have been identified or recorded in the periods presented.

In January 2017, the FASB issued amended guidance to simplify the accounting for goodwill impairment by removing Step 2 of the goodwill impairment test. A goodwill impairment will now be measured as the amount by which a reporting unit’s carrying value exceeds its fair value, limited to the amount of goodwill allocated to that reporting unit. This guidance is to be applied on a prospective basis effective for our interim and annual periods beginning after January 1, 2020, with early adoption permitted for any impairment tests performed after January 1, 2017. We are currently evaluating the timing of adoption and the effect, if any, of this guidance on our consolidated financial statements.

Contingent consideration:  In connection with the purchase of Aquadex, we have an obligation to pay additional consideration that is contingent upon the occurrence of certain future events.  Contingent consideration was recognized at the acquisition date at the estimated fair value of the contingent milestone payments.  The fair value of the contingent consideration is remeasured to its estimated fair value at the end of each reporting period, with changes recorded to earnings.

Common stock warrant liability:  We record the common stock warrant liability at fair value at the date of issuance using primarily a Monte Carlo valuation model (services. See Note 6 to the condensed consolidated financial statements2 – Revenue Recognition, included in Part I, Item 1 of this Quarterly Report on Form 10-Q).  The fair value is remeasured10-Q, for additional disclosures.

Accounts Receivable: Our accounts receivables generally have terms that require payment within 30 days. We did not establish an allowance for doubtful accounts as of March 31, 2023, as we have not incurred any write-offs or experienced a deterioration in the aging of our receivables, and we do not expect to its estimated fair valueexperience write-offs in the future.

Inventories: Inventories consist of finished goods, raw materials and subassemblies and are recorded at the endlower of each reporting period with changes recorded to earnings.cost or net realizable value using the first-in, first-out method.


Stock-Based Compensation: We recognize all share-based payments to employees, directors, and directors,consultants, including grants of stock options restricted stock units (RSUs), warrants and common stock awards, in the consolidated statement of operations and comprehensive loss as an operating expense based on their fair values over the requisite service period.
We compute the estimated fair values of stock options and warrants using the Black-Scholes option pricing model. Market priceas established at the date of grant is used to calculate the fair value of restricted stock units and common stock awards.

Stock-based compensation expense is based on awards ultimately expected to vest and is reduced for estimated forfeitures. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.

Equitydate. Other equity instruments issued to non-employees include RSUs,consist of warrants or options to purchase shares of our common stock. These RSUs, warrants or options are either fully-vestedfully vested and exercisable at the date of grant or vest over a certain period during which services are provided.

We compute the estimated fair values of stock options and warrants using the Black-Scholes option pricing model and market-based warrants using a Monte Carlo valuation model. Market price at the date of grant is used to calculate the fair value of any restricted stock units and common stock awards.

We expense the fair market value of fully vested awards at the time of grant, and of unvested awards over the period in which the related services are received. UnvestedStock-based compensation expense is based on awards ultimately expected to vest and is reduced for estimated forfeitures, except for market-based warrants, which are remeasured toexpensed based on the grant date fair value until they vest.regardless of whether the award vests. Forfeitures are estimated at the time of grant and revised, if necessary, in subsequent periods if actual forfeitures differ from those estimates.


EarningsAccounting for Warrants: We have issued and may continue to issue warrants to purchase shares of common stock through our public and private offerings. We account for such warrants in accordance with ASC 480, Distinguishing Liabilities from Equity, which identifies three categories of freestanding financial instruments that are required to be accounted for as a liability. If determined to be classified as a liability, we will remeasure the fair value of the warrants at each balance sheet date. If determined to be classified as equity, the fair value of the warrants will be measured as of the date of issuance and will not be subject to remeasurement at each balance sheet date.

The fair value of the warrant liability is estimated using a Monte Carlo simulation model using relevant inputs and assumptions based upon the terms of the warrants.

Loss per share: We compute basic earningsBasic loss per share is computed based on the net loss allocable to common stockholders for each period divided by the weighted average number of common shares outstanding. The net loss allocable to common stockholdersSee Note 3 – Stockholders’ Equity below for the nine months ended September 30, 2017, reflects a $1.0 million increase for the net deemed dividend to preferred stockholders provided in connection with the close of the public offering of Series E Convertible Preferred Stock in April of 2017, representing the intrinsic value of the shares at the time of issuance. In addition, the net loss allocable to common stockholders reflects an increase for net deemed dividends of $1.8 million to preferred stockholders provided in connection with the shareholder approval of the Series C and D Convertible Preferred Stock transactions in January of 2017, representing the intrinsic value of the shares at the time of issuance.  additional disclosures.

Diluted earnings per share is computed based on the net loss allocable to common stockholders for each period divided by the weighted average number of common shares outstanding, increased by the number of additional shares that would have been outstanding had the potentially dilutive common shares been issued, and reduced by the number of shares the Company could have repurchased from the proceeds from issuance of the potentially dilutive shares. Potentially dilutive shares of common stock include shares underlying outstanding convertible preferred stock, warrants, stock options and other stock-based awards granted under stock-based compensation plans. These potentially dilutive shares were excluded

Impairment of Long-Lived Assets: Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. If the impairment tests indicate that the carrying value of the asset or asset group is greater than the expected undiscounted cash flows to be generated by such asset or asset group, further analysis is performed to determine the fair value of the asset or asset group. To the extent the fair value of the asset or asset group is less than its carrying value, an impairment loss is recognized equal to the amount the fair value of the asset or asset group is exceeded by its carrying amount. Assets to be disposed of are carried at the lower of their carrying value or fair value less costs to sell. Considerable management judgment is necessary to estimate the fair value of assets or asset groups, and accordingly, actual results could vary significantly from such estimates.

The Company continues to report operating losses and negative cash flows from operations, both of which it considers to be indicators of potential impairment. Therefore, the Company evaluates its long-lived assets for potential impairment at each reporting period. The Company has concluded that its cash flows from the computationvarious long-lived assets are highly interrelated and, as a result, the Company consists of loss per share as their effecta single asset group. As the Company expects to continue incurring losses in the foreseeable future, the undiscounted cash flow step was antidilutive duebypassed, and the Company proceeded to our net loss in eachmeasure fair value of those periods.the asset group. The Company has determined the fair value of the asset group associated with its loaner units by using expected cash flows estimating future discounted cash flows expected from the rental of these units. For recently acquired assets within the asset group, primarily equipment, the Company determined the fair value based on the replacement cost. There have been no impairment losses recognized for the three months ended March 31, 2023 or the year ended December 31, 2022.

Going Concern:Our consolidatedConsolidated financial statements have been prepared and presented on a basis assuming we continue as a going concern. During the years ended December 31, 20162022 and 2015,2021, and through September 30, 2017,March 31, 2023, we incurred losses from operations and net cash outflows from operating activities as disclosed in the consolidated statements of operations and comprehensive loss and cash flows, respectively. As of March 31, 2023, we had an accumulated deficit of $273.9 million, and we expect to incur losses for the foreseeable future. To date, we have been funded by debt and equity financings, and although we believe that we will be able to successfully fund our operations into the future, there can be no assurance that we will be able to do so or that we will ever operate profitably. These factors raise substantial doubt about the Company’s ability to continue as a going concern through at least twelve months from the report date.


We became a revenue generating company onlyrevenue-generating Company after acquiring the Aquadex Business in August 2016. We expect to incur additional losses in the near-term as we grow the Aquadex Business, including investments in expanding our sales and marketing capabilities, purchasing inventory and manufacturing components, investing in clinical research, and complying with the requirements related to being a U.S. public company. To become and remain profitable, we must succeed in expanding the adoption and market acceptance of the Aquadex FlexFlow.System. This will require us to succeed in training personnel at hospitals and effectively and efficiently manufacturing, marketing and distributing the Aquadex FlexFlowSystem and related components. There can be no assurance that we will succeed in these activities, and we may never generate revenues sufficient to achieve profitability.


We may be required During 2022, we closed on an underwritten public offering for aggregate net proceeds of approximately $9.4 million after deducting the underwriting discounts and commissions and offering expenses. See Note 4 –Stockholders’ Equity, to seekthe consolidated financial statements included in Part II, Item 8 of our Annual Report on Form 10-K for the year ended December 31, 2022. The Company will require additional funding to grow our Aquadex Business,its business, which may not be available on terms favorable to us,the Company, or at all. In addition,The Company may receive those funds from the risk that we may not be able to continue as a going concern may make it more difficult to obtain necessary additional funding on terms favorable to us,issuance of equity securities or at all. Furthermore, our ability to continue as a going concern is subject to our ability to achieve commercial milestones.other financing transactions. Should future capital raising be unsuccessful, wethe Company may not be able to continue as a going concern. On April 24, 2017, we closed on an underwritten public equity offering for net proceeds of approximately $8.0 million after deducting the underwriting discounts and commissions and other costs associated with the offering (See Note 4 to the condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q). WeNo adjustments have been made no adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should wethe Company not continue as a going concern.


We believe that our existing capital resources will be sufficient to support our operating plan through December 31, 2023; however, there can be no assurance of this. We will likely seek to raise additional capital to support our growth or other strategic initiatives through debt, equity, or a combination thereof. There can be no assurance the Company will be successful in raising additional capital.

NEW ACCOUNTING PRONOUNCEMENTS


Information regardingIn June 2016, the FASB issued Accounting Standards Update (ASU) 2016-13, “Financial Instruments – Credit Losses.” This ASU added a new accounting pronouncements is included in Note 1 toimpairment model (known as the current period’s condensedexpected credit loss (“CECL”) model) that is based on expected losses rather than incurred losses. Under the new guidance, an entity recognizes as an allowance its estimate of expected credit losses. The CECL model applies to most debt instruments, trade receivables, lease receivables, financial guarantee contracts, and other loan commitments. The CECL model does not have a minimum threshold for recognition of impairment losses, and entities will need to measure expected credit losses on assets that have a low risk of loss. As a smaller reporting company pursuant to Rule 12b-2 of the Securities Exchange Act of 1934, as amended, these changes became effective for the Company on January 1, 2023. The adoption of ASU 2016-13 did not have any impact on the Company’s consolidated financial statements.


FINANCIAL OVERVIEW


We are a medical devicetechnology company focused on commercializing the Aquadex FlexFlow system for ultrafiltration treatment of patients with fluid overload who have failed diuretic therapy. Activities since inception have consisted principally of raising capital, performing research and development, and conducting preclinicalpre-clinical and clinical studies. During 2016, we acquired the Aquadex Business and announced that we were halting all clinical evaluations of our prior technology, the C-Pulse System. Since then, our activities have consisted mainly of expanding our sales and marketing capabilities, performing clinical research, and transferring manufacturing capabilities from Baxter to our facilitiesengaging in Eden Prairie, Minnesota.  At September 30, 2017,new product development. As of March 31, 2023, we had an accumulated deficit of $175$273.9 million, and we expect to incur losses for the foreseeable future. To date, we have been funded by public and private equity financings and debt. Although we believe that we will be able to continue to successfully fund our operations, in the future, there can be no assurance that we will be able to do so or that we will ever operate profitably.

Cost of Goods Sold
In connection with the acquisition of the Aquadex product line, we entered into a manufacturing and supply agreement with Baxter. Cost of sales reflects the agreed-upon price paid to Baxter for the manufacturing of the disposables and consoles. The acquisition closed on August 5, 2016. Prior to that date, we did not have commercial sales or related product costs.

In May 2017, we provided notice to Baxter to cease the manufacturing of the Aquadex product line as of June 30, 2017, and we began transitioning activitiesincrease in house. We expect to begin manufacturing our products in house in the fourth quarter of 2017. We will continue to purchase materials and finished goods from Baxter into the first quarter of 2018.

Cost of salesgross margin percent for the three months ended September 30, 2017, include startup costs for the planning and preparation associated with the transfer of these manufacturing activitiesMarch 31, 2023, compared to our facilities in Eden Prairie, Minnesota. In 2018, we expect our gross margins to improve as volumes increase and we achieve larger efficiencies of scale.

Selling, General and Administrative
Our selling, general and administrative expenses for the three months ended September 30, 2017 have remained consistent with the same period a year ago.  Expenditures during the three months ended September 30, 2017, reflect approximately $0.9 million of incremental expenses relatedMarch 31, 2022, was due primarily to the commercialization of the Aquadex FlexFlow, which we acquired from Baxter in August of 2016. Expenditures during the three months ended September 30, 2016, reflect approximately $0.9 million in transaction fees (accounting, audit, valuation,increased selling prices and, legal fees) incurred in connection with the acquisition of the Aquadex product line.

As we continue to ramp up our sales organization we expect that our selling expenses will continue to increase in future quarters, and that general and administrative expenses will either remain constant or decrease as we continue to streamline activities.

Research and Development
The decrease in research and development expense resulted primarily from our decision to stop enrollment in our two clinical studies for our now discontinued C-Pulse System, which was announced on March 3, 2016.  In July 2016, we announced that we were moving forward with a therapeutic strategy utilizing neuromodulation rather than counterpulsation.  Further, on September 29, 2016, we announced a strategic refocus of our near-term strategy that includes halting all clinical evaluations of the neuromodulation technology to fully focus the Company’s resources on our recently acquired Aquadex system.  We expect to make modest future investments in research and development related to our Aquadex system, and as a result, we expect that our research and development expenditures will increase modestly in future quarters, subject to future decisions on clinical studies.

Interest Expense
The decrease in interest expense is related to the repayment of borrowings outstanding under our prior term loan with Silicon Valley Bank. On August 4, 2016, we repaid all amounts outstanding under this loan facility, totaling $5.5 million.

Loss on Early Retirement of Long-Term Debt
On August 4, 2016, we repaid all amounts outstanding under our prior term loan with Silicon Valley Bank, totaling $5.5 million. In connection with the repayment of this debt, we incurred a $0.5 million loss, including the accelerated write-off of unamortized warrants and debt issuance costs.

Change in Fair Value of Warrant Liability
The gain recognized for the change in fair value of warrant liability relates to the decrease in value of the warrants issued to the investors and placement agent in connection with financings completed on July 26, 2016, November 3, 2016 and January 10, 2017. These warrants were classified as liabilities on our balance sheet as of September 30, 2017 and December 31, 2016 and required to be marked to market at each reporting period, with the changes in fair value recorded on our consolidated statement of operations and comprehensive loss.

Expenditures for the nine months ended September 30, 2016, reflect approximately $0.9 million in transaction fees (accounting, audit, valuation,consulting, marketing initiatives, and accounting and legal fees) incurred in connectionexpenses associated with the acquisition of the Aquadex product line, which we acquired from BaxterCompany’s year-end audit and at-the-market offering filed in August of 2016.March 2023.

As we continue to ramp up our sales organization we expect that our selling expenses will continue to increase in future quarters, and that general and administrative expenses will either remain constant or decrease as we continue to streamline activities.


Research and Development
The decreaseincrease in research andR&D expenses was primarily driven by increased spending on new product development expense resulted primarily fromassociated with our decision to stop enrollment in our two clinical studies for our now discontinued C-Pulse System, which was announced on March 3, 2016.  In July 2016, we announced that we were moving forward with a therapeutic strategy utilizing neuromodulation rather than counterpulsation.  Further, on September 29, 2016, we announced a strategic refocus of our near-term strategy that includes halting clinical evaluations of the neuromodulation technology to fully focus the Company’s resources on our recently acquired Aquadex system.  We expect to make modest future investments in research and development related to our Aquadex system, and as a result, we expect that our research and development expenditures will increase modestly in future quarters, subject to future decisions on clinical studies.pediatric dedicated device.

Interest Expense
The decrease in interest expense is related to the repayment of borrowings outstanding under our prior term loan with Silicon Valley Bank. Beginning January 1, 2016, we began repaying the principal due on this loan, and on August 4, 2016, we repaid all amounts outstanding under this loan facility, totaling $5.5 million.

Loss on Early Retirement of Long-Term Debt
On August 4, 2016, we repaid all amounts outstanding under our prior term loan with Silicon Valley Bank, totaling $5.5 million. In connection with the repayment of this debt, we incurred a $0.5 million loss, including the accelerated write-off of unamortized warrants and debt issuance costs.

Change in Fair Value of Warrant Liability
The gain recognized for the change in fair value of warrant liability relates to the decrease in value of the warrants issued in connection with financings completed on July 26, 2016, November 3, 2016 and January 10, 2017. These warrants were classified as liabilities on our balance sheet as of December 31, 2016 and required to be marked to market at each reporting period, with the changes in fair value recorded on our consolidated statement of operations and comprehensive loss. All Original Warrants were exercised during the period ended September 30, 2017 pursuant to the warrant exercise agreement described above. Accordingly, we remeasured each of these warrants as of the date of exercise, and recorded $1.5 million as an unrealized gain on our statement of operations and comprehensive loss. Although we issued Replacement Warrants under the warrant exercise agreement, the Replacement Warrants are not accounted for as liabilities based on their terms.

Our income tax benefit for the nine months ended September 30, 2016 resulted primarily from a research and development tax credit in Australia.  We have substantially reduced research and development expenditures in Australia, so future research and development tax credits refunds, if any, are expected to decrease.

We generate minimal amounts of income tax expense in connection with activities incurred by our Irish subsidiary.


Liquidity and Capital Resources


Sources of Liquidity
We have funded our operations primarily through cash on hand and a series of equity and debt issuances. On July 26, 2016, pursuant to a Securities Purchase Agreement dated July 20, 2016, we completed an equity financing with an institutional investor of shares of Series B Convertible Preferred Stock and warrants for gross cash proceeds of approximately $3.5 million in a registered direct offering and simultaneous private placement. Also, on October 30, 2016, we entered into securities purchase agreement with an institutional investor pursuant to which we agreed to issue shares of Series C Convertible Preferred Stock, Series D Convertible Preferred Stock and warrants with an aggregate purchase price of $3.8 million in a registered direct offering and simultaneous private placement. The first closing occurred on November 3, 2016, whereby we received $3.6 million in gross proceeds and issued and sold shares of Series C Convertible Preferred Stock, shares of Series D Convertible Preferred Stock and warrants. At the second closing in January 2017, which was subject to receipt of shareholder approval of the transactions, we received $0.2 million in gross proceeds and issued and sold shares of Series D Convertible Preferred Stock and warrants.

In February 2017, we entered into an agreement with the holder of the majority of our outstanding warrants to incent their exercise of warrants for cash on or before March 31, 2017. In exchange for any such exercise, we agreed to provide the investors a replacement warrant to purchase the same number of shares of common stock as were issued upon exercise of each exercised warrants with an exercise price equal to the consolidated closing bid price of our common stock on the date of issuance. In connection with this agreement, the investors exercised all of the original warrants for gross cash proceeds to us of $2.0 million, and we issued 43,396 replacement warrants with exercise prices ranging from $34.6 per share to $99.8 per share.


On August 5, 2016, we entered into a loan agreement with Silicon Valley Bank for proceeds of up to $5.0 million, including a $1.0 million revolving line of credit and a $4.0 million term loan. The term loan expired unused on November 30, 2016 andOctober 18, 2022, the term loan is no longer available to be drawn. Under the revolving line, we may borrow the lesser of $1 million or 80% of our eligible accounts (subject to customary exclusions), minus the outstanding principal balance of any advances under the revolving line.  Advances under the revolving line, if any, will accrue interest at a floating per annum rate equal to 1.75% or 1.0% above the prime rate, depending on whether we have maintained net liquidity in an amount equal to or greater than six times our monthly cash burn amount for the period specified.  Interest on the principal amount outstanding under the revolving line, if any, is payable monthly on the last calendar day of the month until March 31, 2020, at which time all outstanding principal and unpaid interest with respect to any advances under the revolving line are due and payable in full. Advances under the revolving line are subject to various conditions precedent, including our compliance with financial covenants relating to net liquidity relative to monthly cash burn, which we do not currently meet. The revolving line of credit expires on March 31, 2020. We had no borrowings outstanding under the Silicon Valley Bank facility as of September 30, 2017 or December 31, 2016.

The new loan agreement contains customary representations, as well as customary affirmative and negative covenants. Among other restrictions, the negative covenants, subject to exceptions, prohibit or limit our ability to declare dividends or redeem or purchase equity interests; incur additional liens; make loans and investments; incur additional indebtedness; engage in mergers, acquisitions, and asset sales; transact with affiliates; undergo a change in control; add or change business locations; and engage in businesses that are not related to its existing business.  The new loan agreement also requires us to maintain at all times upon the funding date of the initial advance under the revolving line, tested on the last day of each month: (i) net liquidity in an amount equal to or greater than four times our monthly cash burn amount and (ii) unrestricted cash and cash equivalents in accounts with the Bank or its affiliates equal to or greater than 1.25 of the amount of all of our outstanding obligations to the Bank.

Our obligations under the new loan agreement are secured by a security interest in our assets, excluding intellectual property and certain other exceptions. We are subject to a negative pledge covenant with respect to our intellectual property.
In 2014, we entered into a sales agreement with Cowen and Company LLC (“Cowen”), allowing Cowen to sell from time to time, shares of our common stock having an aggregate offering price of up to $40.0 million, through an “at the market” equity offering program (the “Sales Agreement”). We pay Cowen a commission of up to 3.0% of the gross proceeds from the sale of any shares pursuant to the Sales Agreement. There were no issuances of common stock under this facility during the nine months ended September 30, 2017 or 2016. As of September 30, 2017, we had a total of $32.6 million remaining for future sales under the Sales Agreement.

On April 24, 2017, we closed on an underwritten public offering of 209,940 shares of common stock and 23,157,124 shares of Series I convertible preferred stock, for netgross proceeds of approximately $8.0$11.0 million (the “October 2022 Offering”). Net proceeds totaled approximately $9.4 million after deducting the underwriting discounts and commissions and other costs associated with the offering which includedand after giving effect to the underwriters’ full exercise of the underwriter’s over-allotment option to purchase additional shares and warrants. In connection with this offering, we issued a total of 140,000 shares of common stock, 6,400 shares of Series E Convertible Preferred Stock (which were convertible into 320,000 shares of common stock), and warrants to purchase 460,000 shares of common stock. See Note 4 to the condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report on Form 10-Q.their overallotment option.


As of September 30, 2017,March 31, 2023 and December 31, 2016,2022, cash and cash equivalents were $2.5$11.5 million and $1.3$17.7 million, respectively. Prior to our acquisition of the Aquadex FlexFlow in August 2016, we did not have a product approved for commercial sale and focused our resources on developing, manufacturing, and commercializing our C-Pulse System.  In September 2016, we announced a strategic refocus of our near-term strategy that includes halting all clinical evaluations to fully focus our resources on our recently acquired Aquadex Business, taking actions to reduce our cash burn in connection with such strategic refocus and reviewing potential strategic alliances and financing alternatives. Our business strategy and ability to fund our operations in the future dependsdepend in part on our ability to grow ourthe Aquadex Business by establishing a sales force,expanding our salesforce, selling our products to hospitals and other healthcare facilities, and controlling costs. We believe we will need to seek additional funds to finance our operationsfinancing in the fourth quarterfuture, which, to date, has been primarily through offerings of 2017 or first quarter of 2018. We may receive those funds from the proceeds from future warrant exercises, issuances ofour equity securities, or other financing transactions.securities.

Off-Balance Sheet Arrangements


In April 2015, we amended our lease agreement for our office space leased in Eden Prairie, Minnesota, to extend it for an additional thirty-six months beyond its original expiration date. This amended lease agreement expires March 31, 2019.

On August 5, 2016, we entered into an asset purchase agreement for the Aquadex Business with Baxter, whereby we agreed that if we dispose of any of the acquired assets for a price that exceeds $4.0 million within three years of the closing, we will pay Baxter 40% of the amount of such excess; and if shares of our common stock cease to be publicly traded on the Nasdaq Capital Market, Baxter has the option to require us to repurchase, in cash, all or any part of the common shares held by Baxter at a price equal to their fair market value, as determined by a third-party appraiser.
In connection with the acquisition of the Aquadex Business, we entered into a manufacturing and supply agreement with Baxter that will expire within a period not to exceed 18 months from the close of the transaction. In May 2017, we notified Baxter to cease the manufacturing of the Aquadex product line by Baxter as of June 30, 2017. In connection with this notification, we agreed to purchase the remaining Aquadex inventory, which consists mainly of raw materials priced at cost, through February 2018, for a total of $2.4 million.

CONTROLS AND PROCEDURES


Evaluation of Disclosure Controls and Procedures


We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our Exchange Act reports is recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and that such information is accumulated and communicated to our management, including our Chief Executive Officer and ChiefPrincipal Financial Officer (together, the “Certifying“Certifying Officers”), as appropriate, to allow for timely decisions regarding required disclosure.


In designing and evaluating disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired objectives. Also, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. The design of any system of controls is based, in part, upon certain assumptions about the likelihood of future events and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.
As of September 30, 2017,March 31, 2023, the end of the period covered by this report, we conducted an evaluation, under the supervision and with the participation of management, including the Certifying Officers, of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”).Act. Our disclosure controls and procedures are designed to provide reasonable assurance of achieving their stated objectives. Based on their evaluation, our Chief Executive Officer and ChiefPrincipal Financial Officer concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of September 30, 2017.March 31, 2023.


Changes in Internal Controls over Financial Reporting
