Company Overview

Delcath Systems, Inc. is an interventional oncology company focused on the treatment of primary and metastatic liver cancers. Our investigational product, “Melphalan Hydrochloride for Injection for use with the Delcath Hepatic Delivery System” (“Melphalan/HDS”), is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated side effects.

In the United States, Melphalan/HDS is considered a combination drug and device product, is referred to by its chemical name and delivery system, Melphalan/HDS, and is regulated as a drug by the Federal Food and Drug Administration (the “FDA”). The FDA has granted us six orphan drug designations, including three orphan designations for the use of the drug melphalan for the treatment of patients with ocular melanoma liver metastases (“mOM”), hepatocellular carcinoma (“HCC”) and intrahepatic cholangiocarcinoma, a type of primary livery cancer (“ICC”). Melphalan/HDS has not been approved for sale in the United States.

In Europe, our delivery system, without the drug, is commercially available under the trade name Delcath Hepatic CHEMOSAT^® Delivery System for Melphalan (marketed under the name CHEMOSAT and referred to herein as “CHEMOSAT”), where it has been used at major medical centers to treat a wide range of cancers of the liver. The current version of CHEMOSAT is regulated as a Class IIb medical device and received its CE Mark in 2012. We are in an early phase of commercializing CHEMOSAT in select markets in the European Union (the “EU”) where the prospect of securing reimbursement coverage for the procedure is strongest. In 2015 national reimbursement coverage for CHEMOSAT procedures was awarded in Germany. In 2016, coverage levels were negotiated between hospitals in Germany and regional sickness funds. Coverage levels determined via this process are expected to be renegotiated annually. In 2017, Dutch health authorities added CHEMOSAT to their treatment guidelines for patients with ocular melanoma metastatic to the liver, an important step toward eventual reimbursement in the Dutch market.

Our primary research focus is on mOM and ICC and certain other cancers that are metastatic to the liver. Currently there are few effective treatment options for certain cancers in the liver. Traditional treatment options include surgery, systemic chemotherapy, liver transplant, radiation therapy, interventional radiology techniques, and isolated hepatic perfusion. We believe that Melphalan/HDS and CHEMOSAT represent a potentially important advancement in regional therapy for primary liver cancer and certain other cancers metastatic to the liver and are uniquely positioned to treat the entire liver either as a standalone therapy or as a complement to other therapies. We believe the disease states we are investigating represent a multi-billion dollar global market opportunity and a clear unmet medical need.

Our clinical development program for Melphalan/HDS is comprised of the FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma (the “FOCUS Trial”), a global registration clinical trial that is investigating objective response rate in mOM, and the ALIGN Trial, a global Phase 3 clinical trial for ICC (the “ALIGN Trial”). Our product also includes a registry for CHEMOSAT commercial cases performed in Europe and sponsorship of select Investigator Initiated Trials.

The direction and focus of our product is informed by prior clinical development conducted between 2004 and 2010, commercial CHEMOSAT treatment of patients in Europe, and prior regulatory experience with the FDA. Experience gained from this research and development, early European commercial cases and United States regulatory opinion has led to the implementation of several safety improvements to our product and the associated medical procedure.

While we currently utilize third parties to manufacture some components of our product, we also have our own medical device manufacturing operations for certain components of our product and assemble, label and package our products in Queensbury, New York. See the discussion below under the caption “Manufacturing and Quality Assurance.” We commercialize our product in Europe through alliances with third parties.

Cancers in the Liver—A Significant Unmet Need

Cancers of the liver remain a major unmet medical need globally. According to the American Cancer Society’sCancer Facts & Figures 2018 report, cancer is the second leading cause of death in the United States, with an estimated 609,640 deaths and 1.7 million new cases expected to be diagnosed in 2018. Cancer is one of the leading causes of death worldwide, accounting for approximately 9.6 million deaths and 18.1 million new cases in 2018 according to GLOBOCAN, the database of the International Association of Cancer Registries. The financial burden of cancer is enormous for patients, their families and society. The Agency for Healthcare Quality and Research estimates that the direct medical costs (total of all healthcare expenditures) for cancer in the United States in 2015 was $80.2 billion. The liver is often the life-limiting organ for cancer patients and one of the leading causes of cancer death. Patient prognosis is generally poor once cancer has spread to the liver.

Liver Cancers—Incidence and Mortality

There are two types of liver cancers: primary liver cancer and metastatic liver disease. Primary liver cancer (hepatocellular carcinoma or HCC, including intrahepatic bile duct cancers or ICC) originates in the liver or biliary tissue and is particularly prevalent in populations where the primary risk factors for the disease, such ashepatitis-B,hepatitis-C, high levels of alcohol consumption, aflatoxin, cigarette smoking and exposure to industrial pollutants, are present. Metastatic liver disease, also called liver metastasis, or secondary liver cancer, is characterized by microscopic cancer cell clusters that detach from the primary site of disease and travel via the blood stream and lymphatic system into the liver, where they grow into new tumors. These metastases often continue to grow even after the primary cancer in another part of the body has been removed. Given the vital biological functions of the liver, including processing nutrients from food and filtering toxins from the blood, it is not uncommon for metastases to settle in the liver. In many cases patients die not as a result of their primary cancer, but from the tumors that metastasize to their liver. In the United States, metastatic liver disease is more prevalent than primary liver cancer.

Ocular Melanoma

Ocular melanoma is one of the cancer histologies with a high likelihood of metastasizing to the liver. Based on third party research that we commissioned in 2018, we estimate that up to 4,700 cases of ocular melanoma are diagnosed in the United States and Europe annually, and that approximately 55% of these patients will develop metastatic disease. Of metastatic cases of ocular melanoma, we estimate that approximately 90% of patients will develop liver involvement. Once ocular melanoma has spread to the liver, current evidence suggests median overall survival for these patients is generally six to eight months. Currently, there is no standard of care for patients with ocular melanoma liver metastases. Based on the research conducted in 2018, we estimate that approximately 2,000 patients with ocular melanoma liver metastases in the United States and Europe may be eligible for treatment with the Melphalan/HDS.

Intrahepatic Cholangiocarcinoma

Hepatobiliary cancers include HCC and ICC, and are among the most prevalent and lethal forms of cancer. According to GLOBOCAN, an estimated 78,500 new cases of hepatobiliary cancers are diagnosed in the United States and Europe annually. According to the American Cancer Society, approximately 42,030 new cases of these cancers are expected to be diagnosed in the United States in 2019, leading to approximately 31,780 deaths.

ICC is the second most common primary liver tumor and accounts for 3% of all gastrointestinal cancers and 15% of hepatobiliary cases diagnosed in the United States and Europe annually. We believe that 90% of ICC patients are not candidates for surgical resection, and that approximately20-30% of these may be candidates for certain focal interventions. According to third party research that we commissioned in 2018 we estimate that approximately 11,000 ICC patients in the United States and Europe annually could be candidates for treatment with Melphalan/HDS, which we believe represents a significant market opportunity.

According to the American Cancer Society, the overall five-year survival rate for hepatobiliary cancers in the United States is approximately 18%. For patients diagnosed with a localized stage of disease, the American Cancer Society estimates5-year survival at 31%. The American Cancer Society estimates that5-year survival for all cancers is 68%.

About CHEMOSAT and Melphalan/HDS

Our product administers concentrated regional chemotherapy to the liver. This “whole organ” therapy is performed by isolating the circulatory system of the liver, infusing the liver with a chemotherapeutic agent, and then filtering the blood prior to returning it to the patient. During the procedure, known as percutaneous hepatic perfusion, PHP^®, (“PHP therapy”), three catheters are placed percutaneously through standard interventional radiology techniques. The catheters temporarily isolate the liver from the body’s circulatory system, allow administration of the chemotherapeutic agent melphalan hydrochloride directly to the liver, and collect blood exiting the liver for filtration by our proprietary filters. The filters absorb chemotherapeutic agent in the blood, thereby reducing systemic exposure to the drug and related toxic side effects, before the filtered blood is returned to the patient’s circulatory system.

PHP therapy is performed in an interventional radiology suite in approximately two to three hours. Patients remain in an intensive care or step-down unit overnight for observation following the procedure. Treatment with CHEMOSAT and Melphalan/HDS is repeatable, and a new disposable system is used for each treatment. Patients treated in clinical settings are permitted up to six treatments. In commercial treatment settings, patients have received up to eight treatments. In the United States, melphalan hydrochloride for injection will be included as part of the product offering, if approved. In Europe, the system is sold separately and used in conjunction with melphalan hydrochloride commercially available from a third party. In our clinical trials, melphalan hydrochloride for injection is provided to both European and United States clinical trial sites.

Recent Developments

On July 11, 2019, we entered into a securities purchase agreement with certain accredited investors pursuant to which we sold to investors an aggregate of 20,000 shares of our Series E convertible preferred stock, par value $0.01 per share (the “Series E Preferred Stock”) at a price of $1,000 per share and a warrant (a “2019 Warrant”) to purchase a number of shares of Common Stock, equal to the number of shares of Common Stock issuable upon conversion of the Series E Preferred Stock purchased by the investor (the “July 2019 Private Placement”). In connection with the July 2019 Private Placement, we exchanged $11.8 million of debt, interest and Series D Warrants for 11,500 shares of Series E Preferred Stock and related 2019 Warrants, $0.1 million in accounts payables for 149 shares of Series E Preferred Stock and related 2019 Warrants and issued 923 shares of Series E Preferred Stock and related 2019 Warrants to certain investors in exchange for a waiver of rights under exchange agreements signed in December 2018 and March 2019 (the “Debt Exchange”).

On August 19, 2019, we entered into a securities purchase agreement with certain accredited investors pursuant to which we sold to investors an aggregate of 9,510 shares of SeriesE-1 convertible preferred stock, par value $0.01 per share (the “SeriesE-1 Preferred Stock”) at a price of $1,000 per share and a warrant (a “2019 Warrant”) to purchase a number of shares of Common Stock of the Company equal to the number of shares of Common Stock issuable upon conversion of the SeriesE-1 Preferred Stock purchased by the investor (the “August 2019 Private Placement” and, collectively with the July 2019 Private Placement, the “Private Placements”).

Each share of Series E Preferred Stock and SeriesE-1 Preferred Stock (collectively, the “Preferred Stock”) was originally convertible at any time at the option of the holder into the number of shares of Common Stock determined by dividing the stated value by the conversion price of $42.00, subject to certain limitations and adjustments (the “Conversion Price”). Except for certain adjustments, the holders of the Preferred Stock are entitled to receive dividends on shares of Preferred Stock equal (on an “as converted” basis) to and in the same form as dividends paid on shares of the Common Stock. Any such dividends that are not paid to the holders of the Preferred Stock will increase the stated value. No other dividends will be paid on shares of Preferred Stock. Each 2019 Warrant had an original exercise price equal to $42.00, subject to adjustment in accordance with the terms of the Warrants (the “Exercise Price”), and became exercisable at any time upon the consummation of the Reverse Split and will be exercisable until 5:00 p.m. (NYC time) on the date that is five years following the date of the Reverse Split.

Pursuant to the terms of the Preferred Stock and the 2019 Warrants, the Conversion Price of the Preferred Stock and the Exercise Price of the 2019 Warrants are subject to adjustment in each of the following circumstances: (i) on the third trading day following the date that the Company effects a reverse stock split (the “Reverse Split Reset Date”), (ii) the date that the initial registration statement covering the shares of Common Stock issuable upon the conversion of the Preferred Stock and the exercise of the 2019 Warrants is declared effective by the SEC (the “Registration Reset Date”), and (iii) in the event that all of the shares of Common Stock which we were required to register with the SEC were not then registered on an effective registration statement, the date that all of the shares underlying the respective Preferred Stock and 2019 Warrants may be sold pursuant to Rule 144 (the “Rule 144 Reset Date,” each of such reset dates, a “Reset Date” and, collectively, the “Reset Dates”). On each Reset Date, the Conversion Price and the Exercise Price were to be reduced, and only reduced, to equal the lesser of (x) the then effective Conversion Price or Exercise Price, as applicable, and (y) 90% of the average of the five daily volume weighted average prices of the Common Stock immediately prior to each Reset Date (the “Reset Formula”). In the event of a reduction in the Exercise Price, the aggregate number of Warrant Shares issuable upon the exercise of the 2019 Warrants would be increased such that the aggregate Exercise Price of the Warrants on the day immediately following such Reset Date is equal to the aggregate Exercise Price immediately prior to such adjustment. In addition, from the date of issuance of the Preferred Stock and Warrants until such time that the Company’s Common Stock is listed or quoted on a national exchange, the Conversion Price and the Exercise Price are subject to price-based anti-dilution protections.

Before giving effect to the Reverse Split, a total of 1,394,478,266 shares of Common Stock were issuable upon the conversion of the Preferred Stock and the exercise of the 2019 Warrants issued in the Private Placements and the Debt Exchange. If holders of all of the shares issuable upon the conversion of the Preferred Stock and the exercise of the 2019 Warrants had demanded that we honor our obligation to issue such shares, the number of shares of Common Stock we would have been required to issue would have exceeded the number of shares of Common Stock we are authorized to issue pursuant to our Amended and Restated Certificate of Incorporation, as amended.

To prevent us from exceeding our Common Stock authorization and to enable us to complete the registration of the shares issuable upon the conversion of the Preferred Stock and the exercise of the 2019 Warrants, on October 29, 2019, we entered into a Waiver and Forbearance Agreement (“Waiver”) with Rosalind Master Fund

LP and Rosalind Opportunities Fund I LP, holders of its Series E and SeriesE-1 Convertible Preferred Stock and related 2019 Warrants (together, “Rosalind”), pursuant to which Rosalind agreed, among other things, to waive our obligation to register for resale 321,408,352 shares of Common Stock issuable to Rosalind (before giving effect to the Reverse Split) (the “Rosalind Shares”) and forbear from exercising its right to liquidated damages under the registration rights agreements entered into in connection with the Private Placements until the earlier of (x) December 28, 2019 (the “Extension Date”), and (y) the date that any of the other holders of the securities issued in the Private Placements became entitled to receive liquidated damages under such registration rights agreements.

On November 7, 2019 the Commission declared effective our registration statement on FormS-1 (File No.:333-233396) pursuant to which we registered a total of 980,557,497 shares of Common Stock (before giving effect to the Reverse Stock Split) for resale or other disposition by the Selling Stockholders. Accordingly, the Registration Reset Date occurred on November 7, 2019. However, pursuant to the Reset Formula, no reduction in the Conversion Price or the Exercise Price occurred on the Registration Reset Date.

Prior to the Reverse Split, an aggregate of 565 shares of Preferred Stock were converted into an aggregate of 9.4 million shares of Common Stock.

On December 24, 2019, we effected the Reverse Split and the Reverse Split Reset Date occurred on December 30, 2019. Pursuant to the Reset Formula, the Conversion Price and the Exercise Price was reduced to $25.36 per share as of the Reverse Split Reset Date. As a consequence of this reduction of the Conversion Price, an additional 648,673 shares of Common Stock became issuable upon the conversion of the Preferred Stock and an additional 657,547 shares of Common Stock became issuable upon the exercise of the 2019 Warrants (collectively, the “Reset Shares”).

Pursuant to the terms of the registration rights agreements entered into in connection with the Private Placements we are required to register a number of shares of our Common Stock that would be issuable assuming that the Conversion Price and the Exercise Price were $16.10 per share, regardless of the actual Conversion Price or the Exercise Price. Pursuant to that requirement, we are registering an additional 1,758,786 shares of our Common Stock (the “Registrable Shares”) even though we are currently obligated to issue only the Reset Shares as a result of the Reverse Split.

We have filed the registration statement of which this prospectus forms a part to register the Rosalind Shares and the Registrable Shares for sale or other disposition be the Selling Stockholders. Because this registration statement will not be declared effective by the SEC on or prior to the Extension Date, we are liable to Rosalind for liquidated damages under the terms of the registration rights agreements relating to the Private Placements and the Debt Exchange until such time as this registration statement is declared effective by the SEC. We do not expect the amount of such liquidated damages to be material. In the event that this registration statement is not declared effective by the SEC on or prior to January 15, 2020, the Rule 144 Reset Date will be deemed to occur with respect to the Series E Preferred Stock. In the event that this registration statement is not declared effective by the SEC on or prior to February 19, 2019, the Rule 144 Reset Date will be deemed to occur with respect to the SeriesE-1 Preferred Stock. Upon the occurrence of either Rule 144 Reset Date, the Conversion Price of the applicable Preferred Stock and the Exercise Price of the related 2019 Warrants may be further reduced which would result in an increase in the number of shares of Common Stock issuable in respect thereof.

Our independent registered public accounting firm has expressed substantial doubt about our ability to continue as a going concern.

Our independent registered public accounting firm issued a report dated June 14, 2019 in connection with the audit of our financial statements as of December 31, 2018, which included an explanatory paragraph describing the existence of conditions that raise substantial doubt about our ability to continue as a going concern. In addition, the notes to our financial statements for the year ended December 31, 2018, included in our Annual Report on Form10-K filed with the Commission on June 14, 2019, contain a disclosure describing the existence of conditions that raise substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern is dependent upon our ability to obtain substantial additional funding in connection with our continuing operations. Adequate additional financing may not be available to us on acceptable terms, or at all. If the Company is unable to raise additional capital and/or enter into strategic alliances when needed or on attractive terms, Delcath would be forced to delay, reduce or eliminate its research and development programs or any commercialization efforts. The Company’s consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty. If the Company is not able to continue as a going concern, it is likely that holders of its Common Stock will lose all of their investment.

Drug development is an inherently uncertain process with a high risk of failure at every stage of development. Delcath received a complete response letter from the FDA declining to approve our existing New Drug Application, or NDA, in its current form.

Preclinical testing and clinical trials are long, expensive and highly uncertain processes and failure can unexpectedly occur at any stage of clinical development. Drug development is very risky, and it takes several years to complete clinical trials. The start or end of a clinical trial is often delayed or halted due to changing regulatory requirements, manufacturing challenges, required clinical trial administrative actions, slower than anticipated patient enrollment, changing standards of care, availability or prevalence of use of a comparator treatment or required prior therapy, clinical outcomes including insufficient efficacy, safety concerns, or our own financial constraints.

In response to our NDA, which the Company submitted to FDA in August 2012 seeking approval for use of our Melphalan/HDS Kit for the treatment of patients with ocular melanoma of the liver, in September 2013, the FDA denied approval of the NDA in its current form and issued a complete response letter (CRL). A CRL is issued by the FDA when the review of an NDA is completed, and deficiencies remain that preclude approval of the NDA in its current form. The deficiencies in the CRL included, but were not limited to, a statement that Delcath must perform additional “well-controlled randomized trial(s) to establish the safety and efficacy of Melphalan/HDS Kit using overall survival as the primary efficacy outcome measure” and which “demonstrates that the clinical benefits of Melphalan/HDS Kit outweigh its risks.” The FDA also required that the additional clinical trial(s) be conducted using the product the Company intends to market. Prior to conducting additional clinical trials, Delcath must satisfy certain other requirements of the CRL, including, but not limited to, product quality testing and human factors information.

Delcath has initiated a pivotal Phase 3 trial in ocular melanoma metastases. Delcath had a SPA agreement with FDA for this study, which was initially designed as a randomized trial with a primary endpoint of overall survival. We subsequently amended the protocol so that the trial is anon-randomized,single-arm study with a primary endpoint of objective response rate. Although the changes to the protocol invalidated the SPA agreement, FDA stated that it would not object to Delcath conducting a study outside of a SPA agreement. However, Delcath will need to justify how the results of the study support a favorable risk-benefit assessment, particularly whether the response rate is sufficient to overcome the toxicity of Melphalan/HDS.

In addition, Delcath conducts and participates in numerous clinical trials with a variety of study designs, patient populations and trial endpoints to support additional indications for Melphalan/HDS and HDS with other drug therapies. In 2014, Delcath initiated a Phase 2 clinical trial with Melphalan/HDS for hepatocellular carcinoma (“HCC”) in both the United States and Europe. In 2015, the Phase 2 clinical trial for HCC was expanded to include a cohort of patients with intrahepatic cholangiocarcinoma, a type of primary livery cancer (“ICC”). The trial for this cohort was conducted at the same centers participating in the Phase 2 HCC trial. Unfavorable or inconsistent clinical data from clinical trials, including the Phase 2 clinical trial for HCC, the market’s perception of these clinical data or FDA’s perception of this clinical data, may adversely impact our ability to obtain approval, and our financial condition. Additionally, even if the results of our Phase 2 clinical trial for HCC and ICC are positive, there is a substantial risk that it will fail to have positive results in Phase 3 clinical trials with regard to efficacy, safety or other clinical outcomes and may never obtain regulatory approval.

The Company does not expect to generate significant revenue for the foreseeable future.

Delcath’s entire focus has been on developing, commercializing, and obtaining regulatory authorizations and approvals of CHEMOSAT^® and Melphalan/HDS and currently has only developed this system for the treatment of cancers in the liver. If CHEMOSAT and Melphalan/HDS for the treatment of cancers in the liver fail as commercial products, the Company has no other products to sell. In addition, since CHEMOSAT currently is approved for commercialization solely in the European Economic Area (the “EEA”) and limited other jurisdictions, if medac Gesellschaft für klinische Spezialpräparate mbH (“medac”), our third-party distributor, is unsuccessful in commercializing the product in the EEA and/or if Melphalan/HDS is not approved in the United States and elsewhere, the Company will have no means of generating revenue. In September 2013, the FDA issued a CRL with respect to the Company’s NDA for Melphalan/HDS. A CRL is issued by the FDA when the review of a file is completed and questions remain that preclude approval of the NDA in its then current form. Accordingly, Delcath does not expect to realize any revenues from product sales in the United States in the next several years, if at all. As a result, our revenue sources are, and will remain, extremely limited until the Company’s product candidates are approved by the FDA or other additional foreign regulatory agencies and successfully marketed. CHEMOSAT and Melphalan/HDS may not be successful in clinical trials, approved by the FDA or other additional foreign regulatory agency or marketed at any time in the foreseeable future or at all.

Continuing losses may exhaust our capital resources.

As of September 30, 2019, the Company had $15.5 million in cash and cash equivalents. Delcath has had minimal revenue to date, and has a substantial accumulated deficit, recurring operating losses and negative cash flow. For the years ended December 31, 2018 and 2017, the Company incurred net losses of approximately $19.2 million and $45.1 million, respectively and expects to continue to incur losses in 2019. To date, the Company has funded operations through a combination of private placements and public offerings of its securities, including convertible notes. If Delcath continues to incur losses, the Company may exhaust its capital resources, and as a result may be unable to complete its clinical trials, engage in product development and the regulatory approval process and commercialization of CHEMOSAT and Melphalan/HDS or any other versions of these products. If Delcath is unable to raise capital or generate sufficient revenue, it may not be able to pay its debts when they become due and may have to seek protection from the bankruptcy courts or enter into a receivership.

If the Company cannot raise additional capital, its potential to generate future revenues will be significantly limited since it may not be able to further commercialize CHEMOSAT and Melphalan/HDS, complete its clinical trials or conduct future product development and clinical trials.

The Company will require additional financing to complete its clinical trial program or seek other approvals, to conduct future development and clinical trials and to further commercialize its product in the EEA and any other markets where the Company may receive approval for its products. In addition, Delcath is obligated to make payments under long-term research and development obligations and lease agreements. If financing is unavailable to make the required payments under these agreements, the Company could be subject to legal liability and its ability to complete product development projects or clinical trials could be impaired. The Company does not know if additional financing will be available when needed at all or on acceptable terms. If unable to obtain additional financing as needed, the Company may not be able to further commercialize CHEMOSAT and Melphalan/HDS, obtain regulatory approvals or complete its development projects or clinical trials, which would result in a complete loss of an investment in our securities.

Our liquidity and capital requirements will depend on numerous factors, including:

•

clinical studies, including a Phase 3 clinical trial in ocular melanoma liver metastases and a registration trial in ICC;

•

the timing and costs of our various United States and foreign regulatory filings, obtaining approvals and complying with regulations;

•

the timing and costs associated with developing our manufacturing operations;

•

the timing of product commercialization activities, including marketing and distribution arrangements overseas;

•

the timing and costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights; and

•

the impact of competing technological and market developments.

Insufficient funds may require us to curtail or stop our commercialization activities, regulatory submissions or ongoing activities for regulatory approval, research and development and clinical trials, which will significantly limit our potential to generate future revenues.

Risks Related to FDA and Foreign Regulatory Approval

Our failure to obtain, or delays in obtaining, regulatory approvals may have a material adverse effect on our business, financial condition and results of operations.

CHEMOSAT and Melphalan/HDS are subject to extensive and rigorous government regulation by the FDA and other foreign regulatory agencies. The FDA regulates the research,development, pre-clinical and clinical testing, manufacture, safety, effectiveness, record keeping, reporting, labeling, storage, approval, advertising, promotion, sale, distribution, import and export of pharmaceutical and medical device products. Failure to comply with FDA and other applicable regulatory requirements may, either before or after product approval, subject us to either civil or criminal administrative or judicially-imposed sanctions and/or other penalties.

In the United States, the FDA regulates drug and device products under the Federal Food, Drug, and Cosmetic Act and its implementing regulations. Melphalan/HDS is subject to regulation by the FDA as a combination product, which means it is composed of both a drug product and device product. If marketed individually, each component would therefore be subject to different regulatory pathways and reviewed by different centers within the FDA. A combination product, however, is assigned to a center that will have primary jurisdiction overits pre-market review and regulation based on a determination of the product’s primary mode of action, which is the single mode of action that provides the most important therapeutic action. In the case of Melphalan/HDS, the primary mode of action is attributable to the drug component of the product, which means that the Center for Drug Evaluation and Research has primary jurisdiction overits pre-market development and review.

The Company is not permitted to market Melphalan/HDS in the United States unless and until it obtains regulatory approval from the FDA. To market the product in the United States, Delcath must submit to the FDA and obtain FDA approval of an NDA. An NDA must be supported by extensive clinical and preclinical data, as well as extensive information regarding chemistry, manufacturing and controls, or CMC, to demonstrate the safety and effectiveness of the applicable product candidate. The number and types of preclinical studies and clinical trials that will be required varies depending on the product candidate, the disease or condition that the product candidate is designed to target and the regulations applicable to any particular product candidate. Despite the time and expense associated with preclinical and clinical studies, failure can occur at any stage, and the Company could encounter problems that cause it to repeat or perform additional preclinical studies, CMC studies or clinical trials. The FDA and similar foreign authorities could delay, limit or deny approval of a product candidate for many reasons, including because they:

•

may not deem a product candidate to be adequately safe and effective;

•

may determine that the risk: benefit profile is not favorable;

•

may not find the data from preclinical studies, CMC studies and clinical trials to be sufficient to support a claim of safety and efficacy;

•

may interpret data from preclinical studies, CMC studies and clinical trials significantly differently than the Company;

•

may not approve the manufacturing processes or facilities associated with our product candidates;

•

may change approval policies (including with respect to our product candidates’ class of drugs) or adopt new regulations; or

•

may not accept a submission due to, among other reasons, the content or formatting of the submission.

Furthermore, we cannot be certain that we or our present or future third-party manufacturers or suppliers will be able to comply with the cGMP regulations and other ongoing FDA regulatory requirements. If we or our present or future third-party manufacturers or suppliers are not able to comply with these requirements, the FDA may require us to recall our products from distribution or withdraw any potential approvals of an NDA for that product.

Undesirable side effects caused by any product candidate that Delcath develops could result in the denial of regulatory approval by the FDA or other regulatory authorities for any or all targeted indications or cause us to evaluate the future of our development programs. The regulatory review and approval process is lengthy, expensive and inherently uncertain. As part of the U.S. Prescription Drug User Fee Act, the FDA has a goal to review and act on a percentage of all submissions in a given time frame. In August 2012, the Company submitted the Melphalan/HDS NDA seeking an indication for ocular melanoma liver metastases. In September 2013, the FDA declined to approve the NDA and issued a CRL. The deficiencies in the CRL included, but were not limited to, a statement that the Company must perform additional “well-controlled randomized trial(s) to establish the safety and efficacy of Melphalan/HDS using overall survival as the primary efficacy outcome measure” and which “demonstrates that the clinical benefits of Melphalan/HDS outweigh its risks.” The FDA also requires that the additional clinical trial(s) be conducted using the product the Company intends to market. Prior to conducting additional clinical trials, Delcath must satisfy certain other requirements of the CRL, including, but not limited to, product quality testing and human factors information. However, even if the Company completes its clinical trials and satisfies all the requirements of the CRL, it may not obtain regulatory approval from the FDA. Continued failure to obtain, or additional delays in obtaining, regulatory approvals may:

•

adversely affect the commercialization of the current version of CHEMOSAT and Melphalan/HDS or any products that the Company develops in the future;

•

impose additional costs on Delcath;

•

diminish any competitive advantages that may be attained; and

•

adversely affect the Company’s ability to generate revenues.

Delcath has obtained the right to affix the CE Mark for the Delcath Hepatic CHEMOSAT Delivery System as a medical device for the delivery of melphalan. Since the Company may only promote the device within this specific indication, if physicians are unwilling to obtain melphalan separately for use with CHEMOSAT, Delcath’s ability to commercialize CHEMOSAT in the EEA will be significantly limited.

In the EEA, CHEMOSAT is regulated as a Class IIb medical device indicated for the intra-arterial administration of a chemotherapeutic agent, melphalan hydrochloride, to the liver with additional extracorporeal filtration of the venous blood return. Delcath’s ability to market and promote CHEMOSAT is limited to this approved indication. To the extent that the Company’s promotion of CHEMOSAT is found to be outside the scope of its approved indication, Delcath may be subject to fines or other regulatory action, limiting its ability to commercialize CHEMOSAT in the EEA.

The Company is limited to marketing CHEMOSAT in the EEA as a medical device for the delivery of melphalan. If physicians are unwilling to obtain melphalan separately for use with CHEMOSAT, Delcath’s ability to commercialize CHEMOSAT in the EEA will be significantly limited. Delcath’s product instructions and indication reference the chemotherapeutic agent melphalan. However, no melphalan labels in the EEA reference Delcath’s product, and the labels vary from country to country with respect to the approved indication of the drug and its mode of administration. As a result, the delivery of melphalan with Delcath’s device may not be within the applicable label with respect to some indications in some Member States of the EEA where the drugs are authorized for marketing. Physicians intending to use CHEMOSAT must obtain melphalan separately for use with CHEMOSAT and must use melphalan independently at their discretion. If physicians are unwilling to obtain melphalan separately from CHEMOSAT and/or to prescribe the use of melphalan independently, the Company’s sales opportunities in the EEA will be significantly impaired.

While the Company has obtained the right to affix the CE Mark, it will be subject to significant ongoing regulatory obligations and oversight in the EEA and in any other country where it receives marketing authorization or approval.

In April 2012, the Company obtained the required certification from its European Notified Body, enabling Delcath to complete an EC Declaration of Conformity with the essential requirements of the EU Medical Devices Directive and affix the CE Mark to the Generation Two version of CHEMOSAT. In order to maintain the right to affix the CE Mark in the EEA, the Company is subject to compliance obligations, and any material changes to the approved product, such as manufacturing changes, product improvements or revised labeling, may require further regulatory review. Additionally, the Company is subject to ongoing audits by its European Notified Body, and the right to affix the CE Mark to the Generation Two version of CHEMOSAT may be withdrawn for a number of reasons, including the later discovery of previously unknown problems with the product.

To the extent that CHEMOSAT or Melphalan/HDS is approved by the FDA or any other regulatory agency, Delcath will be subject to similar ongoing regulatory obligations and oversight in those countries where approval is obtained. For example, the Company may be subject to limitations on the approved indicated uses for which the product may be marketed or to the conditions of approval, or requirements for potentially costly post-marketing testing, including Phase IV clinical trials, and surveillance to monitor the safety and efficacy of the product candidate. In addition, if the FDA approves a product candidate, the manufacturing processes, labeling, packaging, distribution, adverse event reporting, storage, advertising, promotion and recordkeeping for the product will be subject to extensive and ongoing regulatory requirements. These requirements include submissions of safety and other post-marketing information and reports, registration, as well as continued compliance with current good manufacturing practice (“cGMPs”), good clinical practices (“GCPs”), and good laboratory practices, which are regulations and guidelines enforced by the FDA for all products in clinical development, for anypre-clinical or clinical trials that the Company conducts post-approval. In addition, post-marketing requirements for CHEMOSAT and Melphalan/HDS may include implementation of a risk evaluation and mitigation strategies (“REMS”) program to ensure that the benefits of the product outweigh its risks. A REMS may include a medication guide, a patient package insert, a communication plan to healthcare professionals, restrictions on distribution or use and/or other elements to assure safe use of the product.

Later discovery of previously unknown problems with a product, including adverse events of unanticipated severity or frequency, or with our third-party manufacturers or manufacturing processes, or failure to comply with regulatory requirements, may result in, among other things:

•

refusals or delays in the approval of applications or supplements to approved applications;

•

refusal of a regulatory authority to review pending market approval applications or supplements to approved applications;

•

restrictions on the marketing or manufacturing of the product, withdrawal of the product from the market or voluntary or mandatory product recalls or seizures;

•

fines, Warning Letters or untitled letters, or holds on clinical trials;

•

import or export restrictions;

•

injunctions or the imposition of civil or criminal penalties;

•

restrictions on product administration, requirements for additional clinical trials or changes to product labeling or REMS programs; or

•

recommendations by regulatory authorities against entering into governmental contracts with us.

If the Company is not able to maintain regulatory compliance, it may lose any marketing approval that it may have obtained and may not achieve or sustain profitability, which would have a material adverse effect on the business, results of operations, financial condition and prospects of the Company.

The development and approval process in the United States will take many years, require substantial resources and may never lead to the approval of Melphalan/HDS by the FDA for use in the United States.

The Company cannot sell or market Melphalan/HDS with melphalan or other chemotherapeutic agents in the United States without prior FDA approval of an NDA for Melphalan/HDS. Although melphalan and other drugs have been approved by the FDA for use as chemotherapeutic agents, regulatory approval is required in the United States for the combined medical device component and drug component and the specific indication, dose and route of administration of melphalan or other chemotherapeutic agents or compounds used in our system. The Company is seeking approval of Melphalan/HDS for a substantially higher dose of melphalan than prior approved doses of melphalan and such other chemotherapeutic agents or other compounds. Delcath must obtain separate regulatory approvals for Melphalan/HDS with melphalan and every other chemotherapeutic agent or other compound used with the system that Delcath intends to market, and all the manufacturing facilities used to manufacture components or assemble our system must be inspected and meet legal requirements. Securing regulatory approval requires the submission ofextensive pre-clinical and clinical data and other supporting information for each proposed therapeutic indication in order to establish to the FDA’s satisfaction the product’s safety, efficacy, potency and purity for each intended use.The pre-clinical testing and clinical trials of Melphalan/HDS with melphalan or any other chemotherapeutic agent or compound the Company uses in its system must comply with the regulations of the FDA and other federal, state and local government authorities in the United States. Clinical development is a long, expensive and uncertain process and is subject to delays. Delcath may encounter delays or rejections for various reasons, including its inability to enroll enough patients to complete the clinical trials. Moreover, approval policies or regulations may change. If the Company does not obtain and maintain regulatory approval for Melphalan/HDS and the use of melphalan or other chemotherapeutic agents, the value of the Company, results of operations and its ability to raise additional capital will be harmed.

In August 2012, Delcath submitted a NDA seeking an indication for ocular melanoma liver metastases for Melphalan/HDS. In September 2013, the FDA issued a CRL indicating that the Company must perform additional well-controlled randomized trial(s) to establish the safety and efficacy of Melphalan/HDS using overall survival as the primary efficacy outcome measure and which demonstrates that the clinical benefits of Melphalan/HDS outweigh its risks. Our current Phase 3 trial in ocular melanoma liver metastases, the FOCUS

Trial, is not randomized and uses a different primary efficacy outcome measure. Failure to obtain FDA approval will have a material adverse effect on Delcath’s business, financial condition and results of operations.

Even if the Company obtains regulatory approval for Melphalan/HDS in the United States, its ability to market Melphalan/HDS would be limited to those uses that are approved.

The FDA closely regulates the post-approval marketing and promotion of drugs, including standards and regulationsfor direct-to-consumer advertising, disseminationof off-label information, industry-sponsored scientific and educational activities and promotional activities involving the Internet. Drugs may be marketed only for the approved indications and in accordance with the provisions of the approved label. If the FDA approves an application for Melphalan/HDS, our ability to market and promote Melphalan/HDS would be limited to the approved indication, so even with FDA approval, Melphalan/HDS may only be promoted in this limited market. Physicians may prescribe legally available drugs for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, impose stringent restrictions on manufacturers’ communicationsregarding off-label use, and FDA approval may otherwise limit our sales practices and our ability to promote, sell and distribute the product. Thus, the Company may only market Melphalan/HDS, if approved by the FDA, for its approved indication and could be subject to enforcement actionfor off-label marketing. Further, if there are any modifications to the product, including changes in indications, labeling or manufacturing processes or facilities, Delcath may be required to submit and obtain FDA approval of a new or supplemental NDA, which may require the Company to develop additional data or conduct additional preclinical studies and clinical trials. Failure to comply with these requirements can result in adverse publicity, Warning Letters, corrective advertising and potential civil and criminal penalties.

If future clinical trials are unsuccessful, significantly delayed or not completed, the Company may not be able to market Melphalan/HDS for other indications.

The clinical trial data on our product is limited to specific types of liver cancer. In 2010, the Company concluded a Phase 3 clinical trial of Melphalan/HDS in patients with metastatic ocular and cutaneous melanoma to the liver and also completeda multi-arm Phase 2 clinical trial of Melphalan/HDS in patients with primary and metastatic melanoma stratified into four arms.

The Company has initiated an open-label Phase 3 clinical trial in ocular melanoma liver metastases called the FOCUS Trial. The Company has also initiated a Phase 3 registration trial to treat patients with intrahepatic cholangiocarcinoma (ICC), called the ALIGN trial, for which the Company has received agreement on a SPA from the FDA.

It may take several years to complete the testing of Melphalan/HDS for use in the treatment of these indications, and failure can occur at any stage of development, for many reasons, including:

•

any pre-clinical or clinical test may fail to produce results satisfactory to the FDA or foreign regulatory authorities;

•

pre-clinical or clinical data can be interpreted in different ways, which could delay, limit or prevent regulatory approval;

•

negative or inconclusive results froma pre-clinical study or clinical trial or adverse medical events during a clinical trial could causea pre-clinical study or clinical trial to be repeated or a program to be terminated, even if other studies or trials relating to the program are successful;

•

the FDA or foreign regulatory authorities can place a clinical hold on a trial if, among other reasons, it finds that patients enrolled in the trial are or would be exposed to an unreasonable and significant risk of illness or injury;

•

Delcath may encounter delays or rejections based on changes in regulatory agency policies during the period in which it is developing a system or the period required for review of any application for regulatory agency approval;

•

enrollment in the Company’s clinical trials may proceed more slowly than expected;

•

the Company’s clinical trials may not demonstrate the safety and efficacy of any system or result in marketable products;

•

the FDA or foreign regulatory authorities may request additional clinical trials, including an additional Phase 3 trial, relating to the Company’s NDA submissions;

•

the FDA or a foreign regulatory authority may change its approval policies or adopt new regulations that may negatively affect or delay Delcath’s ability to bring a system to market or require additional clinical trials; and

•

a system may not be approved for all the requested indications.

The failure or delay of clinical trials could cause an increase in the cost of product development, delay filing of an application for marketing approval or cause the Company to cease the development of Melphalan/HDS for other indications. If Delcath is unable to develop Melphalan/HDS for other indications, the future growth of our business could be negatively impacted. In addition, Delcath has limited clinical data relating to the effectiveness of Melphalan/HDS in certain types of cancer. Such limited data could slow the adoption of CHEMOSAT and Melphalan/HDS and significantly reduce Delcath’s ability to commercialize CHEMOSAT and Melphalan/HDS.

The Company relies on third parties to conduct certain elements of the clinical trials for CHEMOSAT and Melphalan/HDS, and if they do not perform their obligations to Delcath, the Company may not be able to obtain regulatory approvals for its system.

The Company designs the clinical trials for Melphalan/HDS, but relies on academic institutions, corporate partners, contract research organizations and other third parties to assist in managing, monitoring and otherwise carrying out these trials. Delcath relies heavily on these parties for the execution of its clinical studies and control only certain aspects of their activities. Accordingly, the Company may have less control over the timing and other aspects of these clinical trials than if Delcath conducted them entirely on its own. The Company relies upon third parties to conduct monitoring and data collection of its ongoing and future clinical trials, including its Phase 3 ocular melanoma trial and pivotal ICC trial. Although Delcath relies on these third parties to manage the data from these clinical trials, Delcath is responsible for confirming that each of its clinical trials is conducted in accordance with its general investigational plan and protocol. Moreover, the FDA and foreign regulatory agencies require Delcath to comply with GCPs for conducting, recording and reporting the results of clinical trials to assure that the data and results are credible and accurate and that the trial participants are adequately protected. The FDA enforces these GCP regulations through periodic inspections of trial sponsors, principal investigators and trial sites. The Company’s reliance on third parties does not relieve it of these responsibilities and requirements and if Delcath or the third parties upon whom the Company relies for its clinical trials fail to comply with the applicable GCPs, the data generated in its clinical trials may be deemed unreliable and the FDA or other foreign regulatory agencies may require Delcath to perform additional trials before approving our marketing application. The Company cannot assure you that, upon inspection, the FDA will determine that any of its clinical trials comply or complied with GCPs. In addition, Delcath’s clinical trials must be conducted with product that complies with the FDA’s cGMP requirements. The Company’s failure to comply with these regulations may require it to repeat clinical trials, which would delay the regulatory approval process, and may result in a failure to obtain regulatory approval for Melphalan/HDS if these requirements are not met.

Purchasers of CHEMOSAT in the EEA may not receive third-party reimbursement or such reimbursement may be inadequate. Without adequate reimbursement, Delcath may not be able to successfully commercialize CHEMOSAT in the EEA.

The Company has obtained the right to affix the CE Mark for CHEMOSAT, and under the definitive licensing agreement (the “medac License”) for CHEMOSAT commercialization in Europe with medac, medac intends to seek third-party or government reimbursement within those countries in the EEA where it expects to market and sell CHEMOSAT. In Germany, the Company had received a ZE diagnostic-related group code (“ZE Code”), which, beginning in 2016, permits hospitals in Germany to obtain reimbursement for CHEMOSAT procedures. Negotiations on the amount of reimbursement to be received under the ZE Code were concluded in 2016 and the procedure was reimbursed under the ZE Code in 2017. Reimbursement negotiations under the ZE system are conducted annually. Consequently, reimbursement obtained may not be for the full amount sought. In countries where medac is able to obtain reimbursement, local policy could limit the Company’s ability to obtain adequate and consistent reimbursement and limit other sales opportunities in those countries.

In other countries, until medac obtains government reimbursement, it will rely on private payors orlocal pre-approved funds where available. There are also no assurances that third-party payors or government health agencies of Member States of the EEA will reimburse use of CHEMOSAT in the long term or at all. Further, each country has its own protocols regarding reimbursement, so successfully obtaining third party or government health agency reimbursement in one country does not necessarily translate to similar reimbursement in other EEA countries. Physicians, hospitals and other health care providers may be reluctant to purchase CHEMOSAT if they do not receive substantial reimbursement for the cost of using the product from third-party payors or government entities. The lack of adequate reimbursement may significantly limit sales opportunities in the EEA.

The success of our products may be harmed if the government, private health insurers and other third-party payers do not provide sufficient coverage or reimbursement.

The Company’s ability to commercialize CHEMOSAT under the medac License and Melphalan/HDS successfully will depend in part on the extent to which reimbursement for the costs of such products and related treatments will be available from government health administration authorities, private health insurers and other third-party payors. Melphalan/HDS is currently not approved by the FDA. Medicare, Medicaid, private health insurance plans and their foreign equivalents will not reimburse the use of Melphalan/HDS since the product is currently not approved outside the EEA. Delcath will seek reimbursement by third-party payors of the cost of Melphalan/HDS after its use is approved, but there are no assurances that adequate third-party coverage will be available for Delcath to establish and maintain price levels sufficient for the Company to realize an appropriate return on its investment in developing new therapies. Government, private health insurers and other third-party payors are increasingly attempting to contain healthcare costs by limiting both coverage and the level of reimbursement for new therapeutic products approved for marketing. Accordingly, even if coverage and reimbursement are provided by government, private health insurers and third-party payors for uses of our products, market acceptance of these products would be adversely affected if the reimbursement available proves to be unprofitable for healthcare providers.

Implementation of healthcare reforms in the United States and in significant overseas markets may limit the ability to commercialize CHEMOSAT and Melphalan/HDS and the demand for CHEMOSAT and Melphalan/HDS. Healthcare providers may respond to such cost-containment pressures by choosing lower cost products or other therapies. In March 2010, the Patient Protection and Affordable Care Act and Health Care and Education Reconciliation Act of 2010 (“ACA”) was enacted into law in the United States, which included a number of provisions aimed at improving quality and decreasing costs. The Trump administration has taken executive actions and has eliminated the individual shared responsibility penalty portion of ACA. A court decision finding that the ACA is unconstitutional is on appeal.

CHEMOSAT and Melphalan/HDS may not achieve sufficient acceptance by the medical community to sustain our business.

The commercial success of CHEMOSAT and Melphalan/HDS, if approved, will depend upon their acceptance by the medical community and third-party payers as clinically useful, cost effective and safe. Acceptance by the medical community may depend on the extent to which leaders in the scientific and medical communities publish scientific papers in reputable academic journals. If testing and clinical practice do not confirm the safety and efficacy of CHEMOSAT and Melphalan/HDS or even if further testing and clinical practice produce positive results but the medical community does not view these favorably, and CHEMOSAT and Melphalan/HDS as effective and desirable, our efforts to market CHEMOSAT and Melphalan/HDS may fail, which would cause us to cease operation.

Consolidation in the healthcare industry could lead to demands for price concessions.

The cost of healthcare has risen significantly over the past decade and numerous initiatives and reforms initiated by legislators, regulators and third-party payors to curb these costs have resulted in a consolidation trend in the medical device industry. Group purchasing organizations, independent delivery networks and large single accounts in the United States and foreign markets may result in a consolidation of purchasing decisions for potential healthcare provider customers. The Company expects that market demand, government regulation, third-party reimbursement policies and societal pressures will continue to change the worldwide healthcare industry, resulting in further business consolidations and alliances which may exert further downward pressure on the price of CHEMOSAT and Melphalan/HDS and adversely impact our business, financial condition and results of operations.

Further, third-party payors may deny reimbursement if they determine that CHEMOSAT and/or Melphalan/HDS is not used in accordance with established payor protocols regarding cost effective treatment methods or is used outside its approved indication or for forms of cancer or with drugs not specifically approved by the FDA or other foreign regulatory bodies in the future. Without reimbursement, physicians, hospitals and other health care providers will be less likely to purchase CHEMOSAT and/or Melphalan/HDS, thereby harming our results of operations.

Risks Related to Manufacturing, Commercialization and Market Acceptance of CHEMOSAT and Melphalan/HDS

There are three third-party manufacturers of melphalan in certain countries of the EEA of which the Company is aware. If any of these manufacturers fails toprovide end-users with adequate supplies of melphalan or fails to comply with the requirements of regulatory authorities, Delcath may be unable to successfully commercialize our product in the EEA.

Under the current regulatory scheme in the EEA, CHEMOSAT is approved for marketing as a device only, and doctors will separately obtain melphalan for use with CHEMOSAT. Although melphalan has been approved in the EEA for over a decade, the Company is aware that there are currently three approved manufacturers of melphalan in certain countries of the EEA. As a result, there may not be sufficient supply of melphalan for use with CHEMOSAT, and any adverse change in a manufacturer’s commercial operations or regulatory approval status may seriously impair Delcath’s sales opportunities in the EEA. Additionally, melphalan is not available in certain foreign countries outside the EEA where Delcath may seek to market CHEMOSAT. If supply of melphalan remains limited or unavailable, the Company will be unable to commercialize CHEMOSAT in these markets, thereby limiting future sales opportunities.

If the Company cannot maintain or enter into acceptable arrangements for the production of melphalan and other chemotherapeutic agents it will be unable to successfully commercialize Melphalan/HDS in the United States or complete its global Phase 3 trial in ocular melanoma liver metastases, registration trial in ICC, or any future clinical trials.

The Company has entered into a manufacturing and supply agreement with Synerx Pharma, LLC (“Synerx”) and Bioniche Teoranta (“Bioniche”) an affiliate of Mylan, Inc., for the supply of its branded melphalan for injection. The agreement with Synerx and Bioniche currently represents Delcath’s sole source of branded melphalan in the United States. The Company intends to use the melphalan supplied by Synerx and Bioniche to conduct its global Phase 3 trials for ocular melanoma liver metastases and ICC. Delcath may pursue agreements with additional contract manufacturers to produce melphalan and other chemotherapeutic agents that it will use in the future for its clinical trial program and the commercialization of CHEMOSAT and Melphalan/HDS, as well as for labeling and finishing services. The Company may not be able to enter into such arrangements on acceptable terms or at all. Every manufacturer is subject to inspection by FDA and must meet all cGMP regulatory requirements. To manufacture melphalan or other chemotherapeutic agents on its own, Delcath would first have to develop a manufacturing facility that complies with FDA requirements and regulations for the production of melphalan and each other chemotherapeutic agent the Company chooses to manufacture for its system. Developing these resources would be an expensive and lengthy process and would have a material adverse effect on the Company’s revenues and profitability. If Delcath is unable to obtain sufficient melphalan and labeling services on acceptable terms, if it should encounter delays or difficulties in its relationships with current and future suppliers or if current and future suppliers of melphalan do not comply with applicable regulations for the manufacturing and production of melphalan, Delcath’s business, financial condition and results of operations may be materially harmed.

If we cannot successfully manufacture CHEMOSAT and Melphalan/HDS, our ability to develop and commercialize the system would be impaired.

We manufacture certain components of our products, including our proprietary filter media, and assemble and package CHEMOSAT and Melphalan/HDS at our facility in Queensbury, New York. We have established our European headquarters and packaging/labeling/distribution facility in Galway, Ireland where we intend to conduct final manufacturing and assembly in the future. We currently utilizes third-parties to manufacture some components of CHEMOSAT and Melphalan/HDS.

We have a limited manufacturing history and we may not be able to manufacture our products in sufficient commercial quantities, in a cost-effective manner or in compliance with the regulatory requirements applicable to such manufacturing. Additionally, we may have difficulty obtaining components for our products from our third-party suppliers in a timely manner or at all which may adversely affect our ability to deliver CHEMOSAT and Melphalan/HDS to purchasers.

In addition to limiting sales opportunities, delays in manufacturing CHEMOSAT and Melphalan/HDS may adversely affect our ability to obtain regulatory approval in the United States and other jurisdictions. Our ability to conduct timely clinical trials in the United States and abroad depends on our ability to manufacture the system, including sourcing the chemotherapeutic agents or other compounds through third parties in accordance with FDA and other regulatory requirements. If we are unable to manufacture CHEMOSAT and Melphalan/HDS in a timely manner, we may not be able to conduct the clinical trials required to obtain regulatory approval and commercialize our product.

The Company has implemented updated quality systems throughout our organization designed to enable us to satisfy the various international quality system regulations including those of the FDA with respect to products sold in the United States and those established by the International Standards Organization (“ISO”) with respect to products sold in the EEA. The Company is required to maintain ISO 13485 certification for medical devices to be sold in the EEA, which requires, among other items, an implemented quality system that applies to component

quality, supplier control, product design and manufacturing operations. On February 17, 2011, we announced that we had achieved ISO 13485 certification for our Queensbury manufacturing facility. On December 28, 2011, we announced that we had achieved ISO 13485 certification for our Galway, Ireland facility. All Delcath facilities are presently ISO 13485:2016 certified. If our Queensbury, NY fails to maintain compliance with ISO 13485 and FDA cGMP or fails to pass facility inspection or audits, our ability to manufacture at the facility could be limited or terminated. In the future, we may manufacture and assemble CHEMOSAT and Melphalan/HDS in our Galway, Ireland facility or elsewhere in the EEA, and any facilities in the EEA would have to obtain and maintain similar approvals or certifications of compliance.

The Company does not have written contracts with all of its suppliers for the manufacture of components for CHEMOSAT and Melphalan/HDS.

The Company does not have written contracts with all suppliers for the manufacture of components for CHEMOSAT and Melphalan/HDS. If Delcath is unable to obtain an adequate supply of the necessary components or negotiate acceptable terms, it may not be able to manufacture CHEMOSAT and Melphalan/HDS in commercial quantities or in a cost-effective manner, and commercialization of CHEMOSAT and Melphalan/HDS in the United States, the EEA and elsewhere may be delayed. In addition, certain components are available from only a limited number of sources. Components of CHEMOSAT and Melphalan/HDS are currently manufactured for Delcath in small quantities and may require significantly greater quantities to further commercialize the product. The Company may not be able to find alternate sources of comparable components. If Delcath is unable to obtain adequate supplies of components from existing suppliers or needs to switch to an alternate supplier and obtain FDA or other regulatory agency approval of that supplier, commercialization of CHEMOSAT and Melphalan/HDS may be delayed.

Even if the Company receives FDA or other foreign regulatory approvals, Delcath may be unsuccessful in commercializing CHEMOSAT and Melphalan/HDS in markets outside the EEA, because of inadequate infrastructure or an ineffective commercialization strategy.

Outside the EEA, even if the Company obtains regulatory approval from the FDA or other foreign regulatory agencies, its ability to commercialize CHEMOSAT and Melphalan/HDS may be limited due to Delcath’s inexperience in developing a sales, marketing and distribution infrastructure. If the Company is unable to develop this infrastructure in the United States or elsewhere or to collaborate with an alliance partner to market its products in the United States or foreign countries, particularly in Asia, Delcath’s efforts to commercialize CHEMOSAT and Melphalan/HDS or any other product outside of the EEA may be less successful.

Even if the Company is successful in commercializing CHEMOSAT and Melphalan/HDS in the EEA, Delcath may not be successful in the United States and other foreign countries. Each country requires a different commercialization strategy, so the Company’s EEA marketing strategy may not translate to other markets. Without a successful commercialization strategy tailored for each market, Delcath’s efforts to promote and market CHEMOSAT in each of its target markets may fail in any or all of those markets.

The Company’s plan to use collaborative arrangements with third parties to help finance and to market and sell CHEMOSAT and Melphalan/HDS may not be successful.

The Company may be unable to enter into collaborative agreements without additional clinical data or unable to continue a collaborative agreement as a result of unsuccessful future clinical trials. Additionally, Delcath may face competition in its search for alliances. As a result, the Company may not be able to enter into any additional alliances on acceptable terms, if at all. The Company’s collaborative relationships may never result in the successful development or commercialization of CHEMOSAT and Melphalan/HDS or any other product. The success of any collaboration will depend upon Delcath’s ability to perform its obligations under any agreements as well as factors beyond its control, such as the commitment of its collaborators and the timely performance of their obligations. The terms of any such collaboration may permit Delcath’s collaborators to abandon the alliance

at any time for any reason or prevent us from terminating arrangements with collaborators who do not perform in accordance with the Company’s expectations or its collaborators may breach their agreements with the Company. In addition, any third parties with which the Company collaborates may have significant control over important aspects of the development and commercialization of Delcath’s products, including research and development, market identification, marketing methods, pricing, composition of sales force and promotional activities. Delcath is not able to control or influence the amount and timing of resources that any collaborator may devote to the Company’s research and development programs or the commercialization, marketing or distribution of its products. The Company may not be able to prevent any collaborators from pursuing alternative technologies or products that could result in the development of products that compete with CHEMOSAT and Melphalan/HDS or the withdrawal of their support for its products. The failure of any such collaboration could have a material adverse effect on its business.

If the Company fails to overcome the challenges inherent in international operations, its business and results of operations may be materially adversely affected.

Currently the Company has only received authorization to market CHEMOSAT in the EEA, and intends to seek similar authorization or approvals in other foreign countries. As a result, Delcath expects international sales of its products to account for a significant portion of its revenue, which exposes Delcath to risks inherent in international operations. To accommodate the Company’s international sales, Delcath will need to further invest financial and management resources to develop an international infrastructure that will meet the needs of its customers. Accordingly, Delcath will face additional risks resulting from its international operations including:

•

difficulties in enforcing agreements and collecting receivables in a timely manner through the legal systems of many countries outside the United States;

•

the failure to satisfy foreign regulatory requirements to market its products on a timely basis or at all;

•

availability of, and changes in, reimbursement within prevailing foreign healthcare payment systems;

•

difficulties in managing foreign relationships and operations, including any relationships that the Company establishes with foreign sales or marketing employees and agents;

•

limited protection for intellectual property rights in some countries;

•

fluctuations in currency exchange rates;

•

the possibility that foreign countries may impose additional withholding taxes or otherwise tax its foreign income, impose tariffs or adopt other restrictions on foreign trade;

•

the possibility of any material shipping delays;

•

significant changes in the political, regulatory, safety or economic conditions in a country or region;

•

protectionist laws and business practices that favor local competitors; and

•

trade restrictions, including the imposition of, or significant changes to, the level of tariffs, customs duties and export quotas.

If the Company fails to overcome the challenges it encounters in its international operations, Delcath’s business and results of operations may be materially adversely affected.

Rapid technological developments in treatment methods for liver cancer and competition with other forms of liver cancer treatments could affect the Company’s ability to achieve meaningful revenues or profit.

Competition in the cancer treatment industry is intense. CHEMOSAT and Melphalan/HDS compete with all forms of liver cancer treatments that are alternatives to the “gold standard” treatment of surgical resection. Many of the Company’s competitors have substantially greater resources and considerable experience in conducting

clinical trials and obtaining regulatory approvals. If these competitors develop more effective or more affordable products or treatment methods, or achieve earlier product development, Delcath’s revenues or profitability will be substantially reduced.

Delcath has the following six orphan drug designations:

•

the drug melphalan for the treatment of patients with cutaneous melanoma (November 2008)

•

the drug melphalan for the treatment of patients with ocular melanoma (November 2008)

•

the drug melphalan for the treatment of patients with neuroendocrine tumors (May 2009)

•

the drug doxorubicin for the treatment of patients with primary liver cancer (August 2009)

•

the drug melphalan for the treatment of HCC (October 2013)

•

the drug melphalan or the treatment of ICC (July 2015)

If another company has orphan drug designations for the same drug and indication and receives marketing approval before Delcath does, then the Company will be blocked from marketing approval for seven years from the date of its approval for the same indication of use unless the Company can make a showing of the clinical superiority of its drug.

The loss of key personnel could adversely affect the Company’s business.

Our success depends upon the efforts of our employees. The loss of any of the Company’s senior executives or other key employees could harm its business. Competition for experienced personnel is intense and, if key individuals leave us, we could be adversely affected if suitable replacement personnel are not quickly identified and hired. The competition for qualified individuals exists in all functional areas, which makes it difficult to attract and retain the qualified employees we need to operate our business. Our success also depends in part on our ability to attract and retain highly qualified scientific, technical, commercial and administrative personnel. If we are unable to attract new employees and retain our current key employees, Delcath’s ability to compete could be adversely affected and the development and commercialization of our products could be delayed or negatively impacted.

We rely on the proper function, availability and security of information technology systems to operate our business and a cyber-attack or other breach of these systems could have a material adverse effect on our business, financial condition or results of operations.

We rely on information technology systems to process, transmit, and store electronic information in ourday-to-day operations. Similar to other companies, the size and complexity of our information technology systems makes them vulnerable to a cyber-attack, malicious intrusion, breakdown, destruction, loss of data privacy, or other significant disruption. Our information systems require an ongoing commitment of significant resources to maintain, protect, and enhance existing systems and develop new systems to keep pace with continuing changes in information processing technology, evolving systems and regulatory standards. Any failure by us to maintain or protect our information technology systems and data integrity, including from cyber-attacks, intrusions or other breaches, could result in the unauthorized access to personally identifiable information, theft of intellectual property or other misappropriation of assets, or otherwise compromise our confidential or proprietary information and disrupt our operations. Any of these event may cause us to have difficulty preventing, detecting, and controlling fraud, be subject to legal claims and liability, have regulatory sanctions or penalties imposed, have increases in operating expenses, incur expenses or lose revenues as a result of a data privacy breach or theft of intellectual property, or suffer other adverse consequences, any of which could have a material adverse effect on our business, financial condition or results of operations.

We are subject to certain data privacy and security requirements, which are complex and varied among jurisdictions. Any failure to ensure adherence to these requirements could subject us to fines and penalties, and damage our reputation.

We are required to comply with numerous federal and state laws, including state security breach notification laws, state health information privacy laws and federal and state consumer protection laws, which govern the collection, use and disclosure of personal information. Other countries also have, or are developing, laws governing the collection, use and transmission of personal information. In addition, most healthcare providers who may prescribe the products we currently sell or may sell in the future and from whom we may obtain patient health information are subject to privacy and security requirements under the Health Insurance Portability and Accountability Act of 1996 and comparable state laws. The legislative landscape for privacy and data protection continues to evolve, and there has been an increasing amount of focus on privacy and data protection issues with the potential to affect our business, including recently enacted laws in a majority of states requiring security breach notifications. Any of these laws could create liability for us or increase our cost of doing business, and any failure to comply could result in harm to our reputation, and potentially fines and penalties.

Risks Related to Intellectual Property

Intellectual property rights may not provide adequate protection, which may permit third parties to compete against us more effectively.

Our success depends significantly on our ability to maintain and protect our proprietary rights in the technologies and inventions used in or embodied by our product. To protect our proprietary technology, we rely on patent protection, as well as a combination of copyright, trade secret and trademark laws, as well as nondisclosure, confidentiality, license and other contractual restrictions in our manufacturing, consulting, employment and other third party agreements. These legal means may afford only limited protection, however, and may not adequately protect our rights or permit us to gain or keep any competitive advantage.

We have not and may not be able to adequately protect our intellectual property rights throughout the world.

Filing, prosecuting and defending patents on our product and technologies in any or all countries throughout the world could be prohibitively expensive. The requirements for patentability may differ in certain countries, particularly developing countries, and the breadth of patent claims allowed can be inconsistent. In addition, the laws of some foreign countries may not protect our intellectual property rights to the same extent as laws in the United States. Consequently, we may not be able to prevent third parties from copying our inventions in all countries outside the United States. Competitors may use our technologies in jurisdictions where we have not obtained patent protection that covers the commercial products to develop their own competing products that are the same or substantially the same as our commercial product and, further, may export otherwise infringing products to territories where we have patent protection, but judicial systems do not adequately enforce patents to cause infringing activities to be ceased.

We do not have patent rights in certain foreign countries in which a market for our product and technologies exists or may exist in the future. Moreover, in foreign jurisdictions where we do have patent rights, proceedings to enforce such rights could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly, and our patent applications at risk of not issuing, and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. Thus, we may not be able to stop a competitor from marketing and selling in foreign countries products that are the same as or similar to our product and technologies.

Obtaining and maintaining our patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated fornon-compliance with these requirements.

Moreover, the United States Patent and Trademark Office (“USPTO”) and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. In addition, periodic maintenance fees on issued patents often must be paid to the USPTO and foreign patent agencies over the lifetime of the patent. While an unintentional lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction.Non-compliance events that could result in abandonment or lapse of a patent or patent application include, but are not limited to, failure to respond to official actions within prescribed time limits,non-payment of fees and failure to properly legalize and submit formal documents. If we fail to maintain the patents and patent applications covering our product or procedures, we may not be able to stop a competitor from marketing products that are the same as or similar to our product and technologies.

Our success depends in part on our ability to obtain patents, which can be an expensive, time consuming, and uncertain process, and the value of the patents is dependent in part on the breadth of coverage and the relationship between the coverage and the commercial product.

The patent position of medical drug and device companies is generally highly uncertain. The degree of patent protection we require may be unavailable or severely limited in some cases and may not adequately protect our rights or permit us sufficient exclusivity, or to gain or keep our competitive advantage. For example:

•

we might not have been the first to invent or the first to file patent applications on the inventions covered by each of our pending patent applications and issued patents;

•

others may independently develop similar or alternative technologies or duplicate any of our technologies;

•

the patents of others may have an adverse effect on our business;

•

any patents we obtain or license from others in the future may not encompass commercially viable products, may not provide us with any competitive advantages or may be challenged by third parties;

•

any patents we obtain or license from others in the future may not be valid or enforceable; and

•

we may not develop additional proprietary technologies that are patentable The process of applying for patent protection itself is time consuming and expensive and we cannot assure you that we have prepared or will be able to prepare, file and prosecute all necessary or desirable patent applications at a reasonable cost or in a timely manner. It is possible that innovation over the course of development and commercialization may lead to changes in CHEMOSAT and Melphalan/HDS methods and/or devices that cause such methods and/or devices to fall outside the scope of the patent protection we have obtained and the patent protection we have obtained may become less valuable. It is also possible that we will fail to identify patentable aspects of inventions made in the course of development and commercialization activities before it is too late to obtain patent protection on them. In addition, our patents and applications may not be prosecuted and enforced in a manner consistent with the best interests of our business. It is possible that defects of form in the preparation or filing of our patents or patent applications may exist, or may arise in the future, for example, with respect to proper priority claims, inventorship, claim scope or patent term adjustments. Moreover, we cannot assure you that all of our pending patent applications will issue as patents or that, if issued, they will issue in a form that will be advantageous to us.

Our success depends in part on our ability to commercialize CHEMOSAT and Melphalan/HDS prior to the expiration of our patent protection.

Due to the uncertainty of the patent prosecution process, there are no guarantees that any of our pending patent applications will result in the issuance of a patent. Even if we are successful in obtaining a patent, patents have a limited lifespan. In the United States, the natural expiration of a utility patent typically is generally 20 years after it is filed. Various extensions may be available; however, the life of a patent, and the protection it affords, is limited. Without patent protection for our CHEMOSAT and Melphalan/HDS methods and devices, we may be open to competition from generic versions of such methods and devices.

We may in the future become involved in lawsuits to protect or enforce our intellectual property, or to defend our products against assertion of intellectual property rights by a third party, which could be expensive, time consuming and unsuccessful.

Competitors may infringe our patents or misappropriate or otherwise violate our intellectual property rights. To stop any such infringement or unauthorized use, litigation may be necessary. Our intellectual property has not been tested in litigation. There is no assurance that any of our issued patents will be upheld if later challenged or will provide significant protection or commercial advantage. A court may declare our patents invalid or unenforceable, may refuse to stop the other party from using the technology at issue on the grounds that our patents do not cover the technology in question, or may interpret the claims of our patents narrowly, thereby substantially narrowing the scope of patent protection they afford. Because of the length of time and expense associated with bringing new medical drugs and devices to the market, the healthcare industry has traditionally placed considerable emphasis on patent and trade secret protection for significant new technologies. Other parties may challenge patents, patent claims or patent applications licensed or issued to us or may design around technologies we have patented, licensed or developed.

In addition, third parties may initiate legal or administrative proceedings against us to challenge the validity or scope of our intellectual property rights, or may allege an ownership right in our patents, as a result of their past employment or consultancy with us. Many of our current and potential competitors have the ability to dedicate substantially greater resources to defend their intellectual property rights than we can. Accordingly, despite our efforts, we may not be able to prevent third parties from infringing upon or misappropriating our intellectual property. Competing products may also be sold in other countries in which our patent coverage might not exist or be as strong. If we lose a foreign patent lawsuit, alleging our infringement of a competitor’s patents, we could be prevented from marketing our product in one or more foreign countries.

The medical device industry has been characterized by frequent and extensive intellectual property litigation. Our competitors or other patent holders may assert that our products and the methods employed in our products are covered by their patents. Although we have performed a search for third-party patents and believe we have adequate defenses available if faced with any allegations that we infringe these third-party patents, it is possible that CHEMOSAT and Melphalan/HDS could be found to infringe these patents. It is also possible that our competitors or potential competitors may have patents, or have applied for, will apply for, or will obtain patents that will prevent, limit or interfere with our ability to make, have made, use, sell, import or export our product. If our products or methods are found to infringe, we could be prevented from manufacturing or marketing our product.

Companies in the medical drug/device industry may use intellectual property infringement litigation to gain a competitive advantage. In the United States, patent applications filed in recent years are confidential for 18 months, while older applications are not publicly available until the patent issues. As a result, avoiding patent infringement may be difficult. Litigation may be necessary to enforce any patents issued or assigned to us or to determine the scope and validity of third-party proprietary rights. Litigation could be costly and could divert our attention from our business. There are no guarantees that we will receive a favorable outcome in any such litigation. If a third party claims that we infringed its patents, any of the following may occur:

•

we may become liable for substantial damages for past infringement if a court decides that our technologies infringe upon a competitor’s patent;

•

a court may prohibit us from selling or licensing our product without a license from the patent holder, which may not be available on commercially acceptable terms or at all, or which may require us to pay substantial royalties or grant cross-licenses to our patents; and

•

we may have to redesign our product so that it does not infringe upon others’ patent rights, which may not be possible or could require substantial funds or time.

Litigation related to infringement and other intellectual property claims such as trade secrets, with or without merit, is unpredictable, can be expensive and time-consuming, and can divert management’s attention from our core business. If we lose this kind of litigation, a court could require us to pay substantial damages, treble damages, and attorneys’ fees, and could prohibit us from using technologies essential to our product, any of which would have a material adverse effect on our business, results of operations, and financial condition. If relevant patents are upheld as valid and enforceable and we are found to infringe, we could be prevented from selling our product unless we can obtain licenses to use technology or ideas covered by such patents. We do not know whether any necessary licenses would be available to us on satisfactory terms, if at all. If we cannot obtain these licenses, we could be forced to design around those patents at additional cost or abandon the product altogether. Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during this type of litigation. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments. If securities analysts or investors perceive these results to be negative, it could cause the price of our Common Stock to decline.

If others have filed patent applications with respect to inventions for which we already have patents issued to us or have patent applications pending, we may be forced to participate in interference or derivation proceedings declared by the USPTO to determine priority of invention, which could also be costly and could divert our attention from our business. If the USPTO declares an interference and determines that our patent or application is not entitled to a priority date earlier than that of the other patent application, our ability to maintain or obtain those patent rights will be curtailed. Similarly, if the USPTO declares a derivation proceeding and determines that the invention covered by our patent application was derived from another, we will not be able to obtain patent coverage of that invention.

Because of the extensive time required for development, testing and regulatory review of a potential product, it is possible that, before CHEMOSAT and Melphalan/HDS or any other Delcath product can be commercialized, any related patent may expire or remain in force for only a short period following commercialization, thereby reducing any advantages of the patent. Not all of our United States patent rights have corresponding patent rights effective in Europe or other foreign jurisdictions. Similar considerations apply in any other country where we are prosecuting patent applications, have been issued patents, or have decided not to pursue patent protection relating to our technology. The laws of foreign countries may not protect our intellectual property rights to the same extent as do laws of the United States.

Changes in patent law could diminish the value of patents in general, thereby impairing our ability to protect our product and our technologies.

Legislation introduced earlier this decade increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents. The Leahy-Smith Act includes a number of significant changes to United States patent law. These include provisions that affect the way patent applications are prosecuted, redefine prior art, may affect patent litigation, and switch the United States patent system from a“first-to-invent” system to a“first-inventor-to-file” system. Under a“first-inventor-to-file” system, assuming the other requirements for patentability are met, the first inventor to file a patent application generally will be entitled to the patent on an invention regardless of whether another inventor had made the invention earlier. The USPTO recently developed new regulations and procedures to govern administration of the Leahy-Smith Act, and many of the substantive changes to patent law associated with the Leahy-Smith Act, in particular, thefirst-inventor-to-file provisions, only became effective on March 16, 2013. As case law continues to develop in response to this legislation, it is not yet clear what the full impact of the Leahy-Smith Act will have on the operation of our business. However, the Leahy-Smith Act and its implementation could increase the uncertainties and costs surrounding the prosecution of our patent applications and the enforcement or defense of our issued patents.

In addition, patent reform legislation may pass in the future that could lead to additional uncertainties and increased costs surrounding the prosecution, enforcement, and defense of our patents and applications. Furthermore, the United States Supreme Court and the United States Court of Appeals for the Federal Circuit have made, and will likely continue to make, changes in how the patent laws of the United States are interpreted. Similarly, foreign courts have made, and will likely continue to make, changes in how the patent laws in their respective jurisdictions are interpreted. We cannot predict future changes in the interpretation of patent laws or changes to patent laws that might be enacted into law by United States and foreign legislative bodies. Those changes may materially affect our patents or patent applications and our ability to obtain and enforce or defend additional patent protection in the future.

Our trademarks may be infringed or successfully challenged, resulting in harm to our business.

We rely on our trademarks as one means to distinguish our product from the products of our competitors, and we have registered or applied to register many of these trademarks. The USPTO or foreign trademark offices may deny our trademark applications, however, and even if published or registered, these trademarks may be ineffective in protecting our brand and goodwill and may be successfully opposed or challenged. Third parties may oppose our trademark applications, or otherwise challenge our use of our trademarks. In addition, third parties may use marks that are confusingly similar to our own, which could result in confusion among our customers, thereby weakening the strength of our brand or allowing such third parties to capitalize on our goodwill. In such an event, or if our trademarks are successfully challenged, we could be forced to rebrand our product, which could result in loss of brand recognition and could require us to devote resources to advertising and marketing new brands. Our competitors may infringe our trademarks and we may not have adequate resources to enforce our trademark rights in the face of any such infringement.

We may rely primarily on trade secret protection for important proprietary technologies in the European Economic Area.

In addition to patent and trademark protection, we also rely on trade secrets, including unpatentedknow-how, technology and other proprietary information, to maintain our competitive position. Specifically in the European Economic Area (“EEA”), we rely on design patent and trade secret protection for CHEMOSAT and Melphalan/HDS. Without utility patent protection in the EEA covering the current version of CHEMOSAT and Melphalan/HDS, CHEMOSAT and Melphalan/HDS will only be covered by design patent and trade secret protection. Unlike patents, trade secrets are only recognized under applicable law if they are kept secret by restricting their disclosure to third parties. We protect our trade secrets and proprietary knowledge in part through confidentiality

agreements with employees, consultants and other parties. However, certain consultants and third parties with whom we have business relationships, and to whom in some cases we have disclosed trade secrets and other proprietary knowledge, may also provide services to other parties in the medical device industry, including companies, universities and research organizations that are developing competing products. In addition, some of our former employees who were exposed to certain of our trade secrets and other proprietary knowledge in the course of their employment may seek employment with, and become employed by, our competitors. We cannot be assured that consultants, employees and other third parties with whom we have entered into confidentiality agreements will not breach the terms of such agreements by improperly using or disclosing our trade secrets or other proprietary knowledge. Monitoring unauthorized uses and disclosures of our intellectual property is difficult, and we do not know whether the steps we have taken to protect our intellectual property will be effective. In addition, we may not be able to obtain adequate remedies for any such breaches. Enforcing a claim that a party illegally disclosed or misappropriated a trade secret is difficult, expensive and time-consuming, and the outcome is unpredictable. In addition, some courts inside and outside the United States are less willing or unwilling to protect trade secrets.

Trade secret protection does not prevent independent discovery of the technology or proprietary information or use of the same. Competitors may independently duplicate or exceed our technology in whole or in part. If any of our trade secrets were to be lawfully obtained or independently developed by a competitor, we would have no right to prevent them, or those to whom they communicate it, from using that technology or information to compete with us. If we are not successful in maintaining the confidentiality of our technology, the loss of trade secret protection orknow-how relating to CHEMOSAT and Melphalan/HDS will significantly impair our ability to commercialize CHEMOSAT in the EEA, and our value and results of operations will be harmed. In particular, we rely on trade secret protection for the filter media, which is a key component of our system.

Similar considerations apply in other foreign countries where we receive approval as mentioned in the section “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Intellectual Property and Other Rights”. Since we do not have issued patents for the current version of CHEMOSAT and Melphalan/HDS in these countries, our ability to successfully commercialize CHEMOSAT and Melphalan/HDS will depend on our ability to maintain trade secret protection in these markets.

We may be subject to damages resulting from claims that we or our employees have wrongfully used or disclosed alleged trade secrets of our competitors or are in breach ofnon-competition ornon-solicitation agreements with our competitors.

We could in the future be subject to claims that we or our employees have inadvertently or otherwise used or disclosed alleged trade secrets or other proprietary information of former employers, competitors, or other third parties. Although we endeavor to ensure that our employees and consultants do not use the intellectual property, proprietary information,know-how or trade secrets of others in their work for us, we may in the future be subject to claims that we caused an employee to breach the terms of his or hernon-competition ornon-solicitation agreement, or that we or these individuals have, inadvertently or otherwise, used or disclosed the alleged trade secrets or other proprietary information of a former employer or competitor. Litigation may be necessary to defend against these claims. Even if we are successful in defending against these claims, litigation could result in substantial costs and could be a distraction to management. If our defense to those claims fails, in addition to paying monetary damages, a court could prohibit us from using technologies or features that are essential to our product, if such technologies or features are found to incorporate or be derived from the trade secrets or other proprietary information of the former employers or other third parties. An inability to incorporate technologies or features that are important or essential to our product may prevent us from selling our product. In addition, we may lose valuable intellectual property rights or personnel. Moreover, any such litigation or the threat thereof may adversely affect our ability to hire employees or contract with independent sales representatives. A loss of key personnel or their work product could hamper or prevent our ability to commercialize our product.

Risks Related to Products Liability

The Company may be the subject of product liability claims or product recalls, and it may be unable to maintain insurance adequate to cover potential liabilities.

The Company’s business exposes Delcath to potential liability risks that may arise from clinical trials and the testing, manufacture, marketing, sale and use of CHEMOSAT and Melphalan/HDS. In addition, because CHEMOSAT and Melphalan/HDS are intended for use in patients with cancer, there is an increased risk of death among the patients treated with Delcath’s system which may increase the risk of product liability lawsuits related to clinical trials or commercial sales. The Company may be subject to claims against it even if the injury is due to the actions of others. For example, if the medical personnel that use Delcath’s system on patients are not properly trained or are negligent in the use of the system, the patient may be injured, which may subject Delcath to claims. Were such a claim asserted, the Company would likely incur substantial legal and related expenses even if Delcath prevails on the merits. Claims for damages, whether or not successful, could cause delays in clinical trials and result in the loss of physician endorsement, adverse publicity and/or limit the Company’s ability to market and sell the system, resulting in loss of revenue. In addition, it may be necessary for Delcath to recall products that do not meet approved specifications, which would also result in adverse publicity, as well as resulting in costs connected to the recall and loss of revenue. A successful products liability claim or product recall would have a material adverse effect on Delcath’s business, financial condition and results of operations. The Company currently carries product liability and clinical trial insurance coverage, but it may be insufficient to cover one or more large claims.

Risks Related to Delcath’s Common Stock

The market price of our Common Stock has been, and may continue to be volatile and fluctuate significantly, which could result in substantial losses for investors.

The trading price for Delcath’s Common Stock has been, and the Company expects it to continue to be, volatile. The price at which Delcath’s Common Stock trades depends upon a number of factors, including historical and anticipated operating results, the Company’s financial situation, announcements of technological innovations or new products by Delcath or its competitors, its ability or inability to raise the additional capital needed and the terms on which it may be raised, and general market and economic conditions. Some of these factors are beyond the Company’s control. Broad market fluctuations may lower the market price of Delcath’s Common Stock and affect the volume of trading, regardless of the Company’s financial condition, results of operations, business or prospects. Among the factors that may cause the market price of its Common Stock to fluctuate are the risks described in this “Risk Factors” section and other factors, including:

•

fluctuations in quarterly operating results or the operating results of competitors;

•

variance in financial performance from the expectations of investors;

•

changes in the estimation of the future size and growth rate of its markets;

•

changes in accounting principles or changes in interpretations of existing principles, which could affect financial results;

•

failure of its products to achieve or maintain market acceptance or commercial success;

•

conditions and trends in the markets served;

•

changes in general economic, industry and market conditions;

•

success of competitive products and services;

•

changes in market valuations or earnings of competitors;

•

changes in pricing policies or the pricing policies of competitors;

•

announcements of significant new products, contracts, acquisitions or strategic alliances by the Company or its competitors;

•

potentially negative announcements, such as a review of any of our filings by the SEC, changes in accounting treatment or restatements of previously reported financial results or delays in our filings with the SEC:

•

changes in legislation or regulatory policies, practices or actions;

•

the commencement or outcome of litigation involving Delcath, its general industry or both;

•

our filing for protection under federal bankruptcy laws;

•

recruitment or departure of key personnel;

•

changes in capital structure, such as future issuances of securities or the incurrence of additional debt;

•

actual or expected sales of Common Stock by stockholders; and

•

the trading volume of Delcath’s Common Stock.

In addition, the stock markets, in general, the OTC and the market for pharmaceutical companies in particular, may experience a loss of investor confidence. Such loss of investor confidence may result in extreme price and volume fluctuations in Delcath’s Common Stock that are unrelated or disproportionate to the operating performance of its business, financial condition or results of operations. These broad market and industry factors may materially harm the market price of Delcath’s Common Stock and expose it to securities class action litigation. Such litigation, even if unsuccessful, could be costly to defend and divert management’s attention and resources, which could further materially harm the Company’s financial condition and results of operations.

Under certain circumstances, we may become obligated to pay liquidated damages or to issue additional shares of Common Stock under the terms of certain of our outstanding securities.

As described above under “Prospectus Summary – Recent Developments,” we are filing the registration statement of which this prospectus forms a part to register the Rosalind Shares and the Registrable Shares for sale or other disposition be the Selling Stockholders. Because this registration statement will not be declared effective by the SEC on or prior to the Extension Date, we are liable to Rosalind for liquidated damages under the terms of the registration rights agreements relating to the Private Placements and the Debt Exchange until such time as this registration statement is declared effective by the SEC. In the event that this registration statement is not declared effective by the SEC on or prior to January 15, 2020, the Rule 144 Reset Date will be deemed to occur with respect to the Series E Preferred Stock. In the event that this registration statement is not declared effective by the SEC on or prior to February 19, 2019, the Rule 144 Reset Date will be deemed to occur with respect to the SeriesE-1 Preferred Stock. Upon the occurrence of either Rule 144 Reset Date, the Conversion Price of the applicable Preferred Stock and the Exercise Price of the related 2019 Warrants may be further reduced which would result in an increase in the number of shares of Common Stock issuable in respect thereof. We will also be liable for liquidated damages if we fail to comply with certain covenants contained in the registration rights agreements relating to the Private Placements and the Debt Exchange.

Sales of a substantial number of shares of our Common Stock in the public market, or the perception that such sales may occur, could adversely affect the market price of our Common Stock and could impair our ability to raise additional equity capital.

Sales of a substantial number of shares of our Common Stock in the public market, or the perception that such sales may occur, could cause the market price of our Common Stock to decline and could impair our ability to raise capital through the sale of additional equity securities. We cannot predict the effect that future sales of our shares of Common Stock or other equity-related securities would have on the market price of our Common Stock.

The Company has a history of reverse splits, which have severely impacted its Common Stock price.

Since our initial public offering in 2000, we have effected five reverse stock splits, for a cumulative ratio since our IPO of 1:31,360,000,000. Each such reverse split has resulted in an effective decline in the price of our Common Stock. There can be no assurance that we will not be required to effect one or more additional reverse stock splits which could further impact the market price and liquidity of our Common Stock.

Anti-takeover provisions in our Amended and Restated Certificate of Incorporation andBy-laws may reduce the likelihood of a potential change of control, or make it more difficult for our stockholders to replace management.

Certain provisions of our Amended and Restated Certificate of Incorporation andBy-laws could have the effect of making it more difficult for our stockholders to replace management at a time when a substantial number of stockholders might favor a change in management. These provisions include:

•

providing for a staggered board; and

•

authorizing the board of directors to fill vacant directorships or increase the size of its board of directors.

Furthermore, our board of directors has the authority to issue up to 10,000,000 shares of preferred stock in one or more series and to determine the rights and preferences of the shares of any such series without stockholder approval. Any series of preferred stock is likely to be senior to the Common Stock with respect to dividends, liquidation rights and, possibly, voting rights. The board’s ability to issue preferred stock may have the effect of discouraging unsolicited acquisition proposals, thus adversely affecting the market price of our Common Stock.

Our Common Stock is governed under The Securities Enforcement and Penny Stock Reform Act of 1990.

The Securities Enforcement and Penny Stock Reform Act of 1990 requires additional disclosure relating to the market for penny stocks in connection with trades in any stock defined as a penny stock. The Commission has adopted regulations that generally define a penny stock to be any equity security that has a market price of less than $5.00 per share, subject to certain exceptions. Such exceptions include any equity security listed on NASDAQ and any equity security issued by an issuer that has (i) net tangible assets of at least $2,000,000, if such issuer has been in continuous operation for three years; (ii) net tangible assets of at least $5,000,000, if such issuer has been in continuous operation for less than three years; or (iii) average annual revenue of at least $6,000,000, if such issuer has been in continuous operation for less than three years. Unless an exception is available, the regulations require the delivery, prior to any transaction involving a penny stock, of a disclosure schedule explaining the penny stock market and the risks associated therewith. These additional requirements may discourage broker-dealers from effecting transactions in securities that are classified as penny stocks, which could severely limit the market price and liquidity of such securities and the ability of purchasers to sell such securities in the secondary market.

The Company has never declared or paid any dividends to the holders of its Common Stock and does not expect to pay cash dividends in the foreseeable future.

The Company currently intends to retain all earnings for use in connection with the expansion of its business and for general corporate purposes. The board of directors will have the sole discretion in determining whether to declare and pay dividends in the future. The declaration of dividends will depend on profitability, financial condition, cash requirements, future prospects and other factors deemed relevant by the Company’s board of directors. Delcath’s ability to pay cash dividends in the future could be limited or prohibited by the terms of financing agreements that it may enter into or by the terms of any preferred stock that may be authorized and issued. The Company does not expect to pay dividends in the foreseeable future. As a result, holders of Delcath’s Common Stock must rely on stock appreciation for any return on their investment.

If the Company engages in acquisitions, reorganizations or business combinations, it will incur a variety of risks that could adversely affect its business operations or its stockholders.

The Company may consider strategic alternatives, such as acquiring businesses, technologies or products or entering into a business combination with another company. If Delcath does pursue such a strategy, the Company could, among other things:

•

issue equity securities that would dilute current stockholders’ percentage ownership;

•

incur substantial debt that may place strains on its operations;

•

spend substantial operational, financial and management resources in integrating new businesses, personnel, intellectual property, technologies and products;

•

assume substantial actual or contingent liabilities;

•

reprioritize its programs and even cease development and commercialization of CHEMOSAT and Melphalan/HDS;

•

suffer the loss of key personnel, or

•

merge with, or otherwise enter into a business combination with, another company in which Delcath stockholders would receive cash or shares of the other company or a combination of both on terms that certain of the Company’s stockholders may not deem desirable.

Although we intend to evaluate and consider different strategic alternatives, we have no agreements or understandings with respect to any acquisition, reorganization or business combination at this time.

BUSINESS

Company Overview

Delcath Systems, Inc. is an interventional oncology company focused on the treatment of primary and metastatic liver cancers. Our investigational product—Melphalan Hydrochloride for Injection for use with the Delcath Hepatic Delivery System (“Melphalan/HDS”)—is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated side effects. In Europe, our system is commercially available under the trade name Delcath Hepatic CHEMOSAT^® Delivery System for Melphalan (“CHEMOSAT”), where it has been used at major medical centers to treat a wide range of cancers of the liver.

Our primary research focus is on ocular melanoma liver metastases (“mOM”) and intrahepatic cholangiocarcinoma (“ICC”), a type of primary liver cancer, and certain other cancers that are metastatic to the liver. We believe the disease states we are investigating represent a multi-billion dollar global market opportunity and a clear unmet medical need.

Our clinical development program (“CDP”) for Melphalan/HDS is comprised of The FOCUS Clinical Trial for Patients with Hepatic Dominant Ocular Melanoma (the “FOCUS Trial”), a global registration clinical trial that is investigating objective response rate in mOM, and the ALIGN Trial, a global Phase 3 clinical trial for ICC (the “ALIGN Trial”). Our CDP also includes a registry for CHEMOSAT commercial cases performed in Europe and sponsorship of select investigator-initiated trials (“IITs”).

The direction and focus of our CDP for CHEMOSAT and Melphalan/HDS is informed by; prior clinical development conducted between 2004 and 2010, commercial experience with CHEMOSAT cases performed on patients in Europe, and prior regulatory engagement with the FDA. Experience gained from this research and development, early European commercial cases and United States regulatory opinion has led to the implementation of several safety improvements to our product and the associated medical procedure.

In the United States, Melphalan/HDS is considered a combination drug and device product and is regulated as a drug by the FDA. The FDA has granted us six orphan drug designations, including three orphan designations for the use of the drug melphalan for the treatment of patients with mOM, hepatocellular carcinoma and ICC. Melphalan/HDS has not been approved for sale in the United States.

In Europe, the current version of our CHEMOSAT product is regulated as a Class IIb medical device and received its CE Mark in 2012. We are in an early phase of commercializing the CHEMOSAT system in select markets in the European Union (EU) where the prospect of securing reimbursement coverage for the procedure is strongest.

Currently there are few effective treatment options for certain cancers in the liver. Traditional treatment options include surgery, systemic chemotherapy, liver transplant, radiation therapy, interventional radiology techniques, and isolated hepatic perfusion. We believe that CHEMOSAT and Melphalan/HDS represent a potentially important advancement in regional therapy for primary liver cancer and certain other cancers metastatic to the liver and are uniquely positioned to treat the entire liver either as a standalone therapy or as a complement to other therapies.

Cancers in the Liver—A Significant Unmet Need

Cancers of the liver remain a major unmet medical need globally. According to the American Cancer Society’s (“ACS”) Cancer Facts & Figures 2018 report, cancer is the second leading cause of death in the United States, with an estimated 609,640 deaths and 1.7 million new cases expected to be diagnosed in 2018. Cancer is one of the leading causes of death worldwide, accounting for approximately 9.6 million deaths and 18.1 million new cases in 2018 according to GLOBOCAN, the database of the International Association of Cancer Registries. The

financial burden of cancer is enormous for patients, their families and society. The Agency for Healthcare Quality and Research estimates that the direct medical costs (total of all healthcare expenditures) for cancer in the United States in 2015 was $80.2 billion. The liver is often the life-limiting organ for cancer patients and one of the leading causes of cancer death. Patient prognosis is generally poor once cancer has spread to the liver.

Liver Cancers—Incidence and Mortality

There are two types of liver cancers: primary liver cancer and metastatic liver disease. Primary liver cancer (hepatocellular carcinoma or “HCC”, including ICC, originates in the liver or biliary tissue and is particularly prevalent in populations where the primary risk factors for the disease, such ashepatitis-B,hepatitis-C, high levels of alcohol consumption, aflatoxin, cigarette smoking and exposure to industrial pollutants, are present. Metastatic liver disease, also called liver metastasis, or secondary liver cancer, is characterized by microscopic cancer cell clusters that detach from the primary site of disease and travel via the blood stream and lymphatic system into the liver, where they grow into new tumors. These metastases often continue to grow even after the primary cancer in another part of the body has been removed. Given the vital biological functions of the liver, including processing nutrients from food and filtering toxins from the blood, it is not uncommon for metastases to settle in the liver. In many cases patients die not as a result of their primary cancer, but from the tumors that metastasize to their liver. In the United States, metastatic liver disease is more prevalent than primary liver cancer.

Ocular Melanoma

Ocular melanoma is one of the cancer histologies with a high likelihood of metastasizing to the liver. Based on third party research that we commissioned in 2018, we estimate that up to 4,700 cases of ocular melanoma are diagnosed in the United States and Europe annually, and that approximately 55% of these patients will develop metastatic disease. Of metastatic cases of ocular melanoma, we estimate that approximately 90% of patients will develop liver involvement. Once ocular melanoma has spread to the liver, current evidence suggests median overall survival for these patients is generally six to eight months. Currently there is no standard of care for patients with ocular melanoma liver metastases. Based on the research conducted in 2018, we estimate that approximately 2,000 patients with ocular melanoma liver metastases in the United States and Europe may be eligible for treatment with the Melphalan/HDS.

Intrahepatic Cholangiocarcinoma

Hepatobiliary cancers include HCC and ICC and are among the most prevalent and lethal forms of cancer. According to GLOBOCAN, an estimated 78,500 new cases of hepatobiliary cancers are diagnosed in the United States and Europe annually. According to the ACS, approximately 42,030 new cases of these cancers are expected to be diagnosed in the United States in 2019, leading to approximately 31,780 deaths.

ICC is the second most common primary liver tumor and accounts for 3% of all gastrointestinal cancers and 15% of hepatobiliary cases diagnosed in the United States and Europe annually. We believe that 90% of ICC patients are not candidates for surgical resection, and that approximately20-30% of these may be candidates for certain focal interventions. According to third party research that we commissioned in 2018 we estimate that approximately 9,300 ICC patients in the United States and Europe annually could be candidates for treatment with Melphalan/HDS, which we believe represents a significant market opportunity.

According to the ACS, the overall five-year survival rate for hepatobiliary cancers in the United States is approximately 18%. For patients diagnosed with a localized stage of disease, the ACS estimates5-year survival at 31%. The ACS estimates that5-year survival for all cancers is 68%.

About CHEMOSAT and Melphalan/HDS

then filtering the blood prior to returning it to the patient. During the procedure, known as percutaneous hepatic perfusion, PHP^®, (“PHP therapy”), three catheters are placed percutaneously through standard interventional radiology techniques. The catheters temporarily isolate the liver from the body’s circulatory system, allow administration of the chemotherapeutic agent melphalan hydrochloride directly to the liver, and collect blood exiting the liver for filtration by our proprietary filters. The filters absorb chemotherapeutic agent in the blood, thereby reducing systemic exposure to the drug and related toxic side effects, before the filtered blood is returned to the patient’s circulatory system.

PHP therapy is performed in an interventional radiology suite in approximately two to three hours. Patients remain in an intensive care or step-down unit overnight for observation following the procedure. Treatment with CHEMOSAT and Melphalan/HDS is repeatable, and a new disposable system is used for each treatment. Patients treated in clinical settings are permitted up to six treatments. In commercial treatment settings, patients have received up to eight treatments. In the United States, melphalan hydrochloride for injection will be included as part of the system, if approved. In Europe, the system is sold separately and used in conjunction with melphalan hydrochloride commercially available from a third party. In our clinical trials, melphalan hydrochloride for injection is provided to both European and United States clinical trial sites.

Risks associated with the CHEMOSAT and Melphalan/HDS Procedure

As with many cancer therapies, treatment with CHEMOSAT and Melphalan/HDS is associated with adverse events, some of which can be potentially life threatening.

Procedure and Product Refinements

In 2012, we introduced the Generation Two version of the CHEMOSAT system, which offered improved hemofiltration and other device component product enhancements. Reports from treating physicians in both Europe and the United States using the Generation Two CHEMOSAT and Melphalan/HDS, in a commercial setting, have suggested that these product improvements and procedure refinements have improved the safety profile. Since 2017, physicians in Europe and the United States have presented and published the results of research that signaled an improved safety profile, as well as efficacy in multiple tumor types. Collection of adequate safety data on all aspects of the procedure is a major focus of the clinical trials in our current CDP.

Prior United States Regulatory Experience

In August 2012 we submitted a New Drug Application (“NDA”) under Section 505(b)(2) of the Federal Food Drug Cosmetic Act (FFDCA) seeking an indication for the percutaneous intra-arterial administration of melphalan for use in the treatment of patients with metastatic melanoma in the liver, subsequently amended to ocular melanoma metastatic to the liver. Data submitted to the Food and Drug Administration (FDA) included the early clinical trial versions of the system, along with early clinical procedure techniques based on research conducted between 2005 and 2010. A full discourse of this NDA submission, including the outcome of an ODAC panel on May 2, 2013 and the FDA’s issuance of a Complete Response Letter, in September 2013, is provided in our Annual Report for the fiscal year ended December 31, 2018.

Active Clinical Development Program

The focus of our CDP is to generate clinical data for the CHEMOSAT and Melphalan/HDS in various disease states and validate the safety profile of the current version of the product and treatment procedure. We believe that the improvements we have made to CHEMOSAT and Melphalan/HDS and to the PHP therapy have addressed the adverse event profile and procedure-related risks observed during previous Phase 2 and 3 clinical trials. Our CDP is also designed to support clinical adoption of and reimbursement for CHEMOSAT in Europe, and to support regulatory approvals in various jurisdictions, including the United States.

The FOCUS Trial—NCT02678572

On July 27, 2018, after extensive discussions with FDA, we announced an amendment to our Phase 3, randomized clinical trial in ocular melanoma liver metastases which altered the trial protocol to anon-randomized,single-arm study. Under the terms of the amendment, the trial, now titled ASingle-arm, Multi-Center, Open-Label Study to Evaluate the Efficacy, Safety and Pharmacokinetics of Melphalan/HDS Treatment in Patients with Hepatic-Dominant Ocular Melanoma, will enroll a minimum of 80 patients with ocular melanoma metastatic to the liver. Under the new protocol, the primary endpoint for the amended FOCUS trial will be objective response rate (“ORR”). Secondary endpoints will include duration of response, disease control rate, overall survival and progression-free survival. Additional exploratory outcome measures include time to objective response, hepatic progression-free survival, hepatic objective response, and quality of life, safety and other pharmacokinetic measures. Inclusion and exclusion criteria remain unchanged. Patients previously enrolled in the Melphalan/HDS arm of the trial under the previous protocol will continue to be treated and statistically evaluated as part of the amended trial.

The rarity of ocular melanoma, absence of crossover to the experimental trial arm, and the availability of PHP^® Therapy in a commercial setting in Europe have all combined to impede enrollment in this trial under its previous protocol. This amendment was intended to accelerate our timeline to complete trial enrollment while providing a strong scientific case to support an application for approval. However, accrual of new patients in this trial slowed due to the cash limitations we operated under in 2019. We currently have enrolled 79 of 80 patients and anticipate completing enrollment of the 80th patient in the coming weeks.

The amendment invalidated the prior Special Protocol Assessment (“SPA”) agreement for the prior version of the trial. Full details of the registration clinical trial are available at www.clinicaltrials.gov.

The FOCUS Trial is being conducted at leading cancer centers in the United States and Europe. The Moffitt Cancer Center in Tampa, Florida was activated as a participating center in January 2016 with Jonathan Zager, M.D., FACS, Professor of Surgery in the Cutaneous Oncology and Sarcoma Departments and a Senior Member at Moffitt Cancer Center, serving as the trial’s lead investigator. In October 2018, we announced continued rollout of the amended protocol to participating centers in the United States, and expect approximately 30 leading cancer centers in the United States and Europe to participate in the trial.

We believe that ocular melanoma liver metastases represent a significant unmet medical need, and that pursuit of an indication in this disease state represents the fastest path to potential marketing approval of the Melphalan/HDS in the United States.

The ALIGN Trial—NCT03086993

In April 2018 we announced the initiation of a new pivotal trial of Melphalan/HDS to treat patients with ICC titled A Randomized, Controlled Study to Compare the Efficacy, Safety and Pharmacokinetics of Melphalan/HDS Treatment Given Sequentially Following Cisplatin/Gemcitabine versus Cisplatin/Gemcitabine (Standard of Care) in Patients with Intrahepatic Cholangiocarcinoma (The ALIGN Trial). The ALIGN trial is being conducted under a SPA announced in March of 2017. Under the terms of the SPA, the ALIGN Trial will enroll approximately 295 ICC patients at approximately 40 clinical sites in the U.S. and Europe. The primary endpoint is overall survival (“OS”) and secondary and exploratory endpoints include safety, progression-free survival (“PFS”), ORR andquality-of-life measures. The ALIGN Trial is designed to be cost effective and pursued in a financially prudent manner when financial resources permit. The SPA agreement for the ALIGN TRIAL indicates that the pivotal trial design adequately addresses objectives that, if met, would support regulatory requirements for approval of Melphalan/HDS in ICC. However, final determinations for marketing application approval are made by FDA after a complete review of a marketing application and are based on the totality of data in the application.

In October 2018, we announced the enrollment of the first patient in The ALIGN Trial at The University of Tennessee Health Science Center, Methodist University Hospital, and West Cancer Center in Memphis, Tennessee.

Phase 2 Hepatocellular Carcinoma (HCC) & Intrahepatic Cholangiocarcinoma (ICC) Program

In 2014 we initiated a Phase 2 clinical trial program in Europe and the United States, with the goal of obtaining an efficacy and safety signal for Melphalan/HDS in the treatment of HCC and ICC. Due to differences in treatment practice patterns between Europe and the United States, we established separate European and United States trial protocols for the HCC Phase 2 program with different inclusion and exclusion patient selection criteria:

Protocol 201NCT02406508—Conducted in the United States, this trial was intended to assess the safety and efficacy of Melphalan/HDS followed by sorafenib.This trial was terminated earlier than planned and is now closed to enrollment.

Protocol 202 NCT02415036—Conducted in Europe, this trial was intended to assess the safety and efficacy of Melphalan/HDS without sorafenib. The trial will also evaluate overall response rate via mRECIST criteria, progression free survival, characterize the systemic exposure of melphalan and assess patient quality of life.This trial was terminated earlier than planned and is now closed to enrollment.

ICC Cohort—In 2015 we expandedProtocol 202 to include a cohort of patients with ICC. The trial for this cohort was conducted at the same centers participating in the Phase 2 HCC trial.This trial has completed enrollment and data from this study are being analyzed and will be disseminated publicly by the investigators.

ICC Retrospective Data Collection—The original goal to obtain an efficacy signal for the Phase 2 ICC cohort has been satisfied by the result of multicenter patient outcomes identified in the retrospective data collection of our commercial ICC cases conducted by our European investigators. These promising outcomes and observations were discussed with Key Opinion Leaders at a Delcath-organized medical advisory panel meeting and led to the agreement that PHP therapy does “demonstrate an efficacy signal in ICC and is worthy of full clinical investigation.” Data from this retrospective data collection provided important scientific support during our negotiations with the FDA for our SPA for the Pivotal ICC Trial. Data for the retrospective data collection were published in European Radiology in a paper titled “Percutaneous Hepatic Perfusion (Chemosaturation) with Melphalan in Patients with Intrahepatic Cholangiocarcinoma: European Multicentre Study on Safety, Short Term Effects and Survival”. Details of the findings from this study are discussed below under “Recent Data Presentations”.

With the objective of identifying an efficacy signal worthy of further clinical investigation now met, we have terminated enrollment in our Phase 2 program and have closed the Phase 2 trials in order to focus available resources on the FOCUS Trial and the ALIGN Trial.

Clinical trials are long, expensive and highly uncertain processes and failure can unexpectedly occur at any stage of clinical development. The start or end of a clinical trial is often delayed or halted due to changing regulatory requirements, manufacturing challenges, required clinical trial administrative actions, slower than anticipated patient enrollment, changing standards of care, availability or prevalence of use of a comparator treatment or required prior therapy. A substantial portion of the Company’s operating expenses consist of research and development expenses incurred in connection with its clinical trials. See the Company’s consolidated financial statements included in Item 8 of its Annual Report for the fiscal year ended December 31, 2018.

European Investigator Initiated Trials

In addition to the clinical trials in our CDP, we are supporting data generation in other areas. We are currently conducting one IIT in colorectal carcinoma metastatic to the liver (“mCRC”) at Leiden University Medical

Center in the Netherlands. We continue to evaluate other IITs as suitable opportunities present in Europe. We believe IITs will serve to build clinical experience at key cancer centers and will help support efforts to obtain full reimbursement in Europe.

European Clinical Data Generation

On April 2, 2015, we announced the activation of our prospective patient registry in Europe to collect uniform essential patient safety, efficacy, and QoL information using observational study methods. This registry will gather data in multiple tumor types from commercial cases performed by participating cancer centers in Europe. A prospective registry is an organized system that uses observational study methods to collect defined clinical data under normal conditions of use to evaluate specified outcomes for a population defined by a particular disease, condition, or exposure. Registry data is considered to be supportive data and, as such, cannot be used for either registration approval, promotional or competitive claims. However, we believe the patient registry will provide a valuable supportive data repository that contains real-world evidence, from a commercial setting, that can be used to identify further clinical development opportunities, support clinical adoption and reimbursement in Europe.

Recent Data Presentations

In July 2019 we announced that results from a single-institution retrospective study conducted by University Hospital of Tubingen in Germany on the use of the Delcath Hepatic CHEMOSAT^® Delivery System to treat patients with metastatic ocular melanoma with liver metastases were published in the journalCancer Imaging.

The study,Chemosaturation with percutaneous hepatic perfusion of melphalan for liver dominant metastatic uveal melanoma: a single center experience, by Dr. Christoph Artzner, et al, evaluated the safety and efficacy of PHP^® therapy in 16 patients with unresectable liver metastases from ocular melanoma treated with CHEMOSAT between June 2015 and December 2018. Tumor response was evaluated following each PHP treatment using Response Evaluation Criteria in Solid Tumors, and serious adverse events (“SAEs”) were evaluated using Common Criteria for Adverse Events.

The 16 patients underwent a total of 28 PHP treatments. Results of the study in the 15 evaluable patients showed that after the first PHP treatment, nine patients (60%) had a partial response (PR), five patients (33%) stable disease, and one patient (7%) had progressive disease for an initial disease control rate of 93%. Median progression free survival (PFS) after the first treatment was 11.1 months. Six patients received a second PHP treatment, three patients received three treatments, and a single patient received six treatments. Median overall survival (OS) was 27.4 months.

Safety analysis showed that grade three SAEs were observed in 14% of treatments, and these were anemia, leukopenia and thrombocytopenia. The sole grade four SAE observed was in one patient who suffered a cardiac arrest during the first PHP treatment and was removed from the study. Subsequent evaluation discovered this patient had coronary artery occlusion which was successfully treated. Retrospective evaluation of this patient’spre-procedure imaging revealed signs of coronary artery disease, and investigators subsequently modified their screening procedures for cardiovascular risk factors. Investigators stated that most SAEs were grade one or two and that 5% of the reported grade three and four SAEs required additional intervention.

Investigators concluded that for patients with liver-dominant metastatic uveal melanoma, treatment with PHP Therapy had “observed rates for OS and PFS that exceeded the reported outcomes for traditional systemic treatment.” Investigators stated that SAEs were frequent, but most did not require additional intervention, and that care should be taken in patients with suspected coronary heart disease.

In April 2019 we announced that results from a prospective Phase 2 study conducted by Leiden University Medical Center (“LUMC”) in the Netherlands on the use of CHEMOSAT to treat patients with metastatic ocular melanoma with liver metastases were presented at the European Conference on Interventional Oncology annual meeting.

The LUMC study titled “Percutaneous hepatic perfusion with melphalan in patients with unresectable liver metastases from ocular melanoma using the Delcath System’s second-generation hemofiltration system: a prospective phase II study” was conducted by a team led and presented by Dr. Mark Burgmans. The study evaluated 35 patients with unresectable liver metastases from ocular melanoma treated with CHEMOSAT between February 2014 and June 2017. The 35 patients underwent a total of 72 PHP therapy treatments, and tumor response was evaluable in 32 patients. Primary endpoints were overall response, overall survival, and progression free survival. Secondary measures included safety measures and hematologic toxicity.

Results of the study showed that one patient had a complete response and 22 had partial response, for a combined overall response rate of 74.1%. Overall survival was 20.3 months and mean progression free survival was 8.1 months.

Safety analysis showed a total of 14 serious adverse events were recorded. The hematologic toxicities were in a majority of the cases self-limiting and manageable. Investigators concluded that “PHP Therapy with the Generation Two version of CHEMOSAT is an effective and safe treatment for patients with hepatic metastases from ocular melanoma.”

The presentation at the European Conference, an Interventional Oncology updated data previously presented at the 2018 annual conference of the Cardiovascular and Interventional Radiological Society of Europe.

Market Access and Commercial Clinical Adoption

Europe

Delcath’s European subsidiary, Delcath Systems, Ltd., is headquartered in Galway, Ireland. Our marketing strategy in the European Economic Area (the “EEA”) includes establishing strategic alliances with partners that include license, supply, sales and marketing arrangements. In December 2018, Delcath entered into the medac License for CHEMOSAT commercialization in Europe with medac, a privately held, multi-national pharmaceutical company based in Wedel, Germany. Founded in 1970, medac specializes in the treatment and diagnosis of oncological, urological and autoimmune diseases. medac has offices globally, worldwide partner agreements in over 90 countries, and approximately 1,200 employees.

Under the terms of the medac License, Delcath Systems, Ltd. exclusively licenses to medac the right to sell and market CHEMOSAT in all member states of the European Union, Norway, Liechtenstein, Switzerland, and the United Kingdom. The medac License provides for payment by medac to Delcath in a combination of upfront and success-based milestone payments as well as a fixed transfer price per unit of CHEMOSAT and specified royalties.

We believe that medac is a well-suited partner to help advance CHEMOSAT commercialization in the European Union and neighboring countries. medac has offices throughout Europe, a well-established network among oncology key opinion leaders, and organizational scale necessary to help establish CHEMOSAT in the European treatment landscape for cancers of the liver.

Since launching CHEMOSAT in Europe, over 750 commercial treatments have been performed at over 25 leading European cancer centers. Physicians in Europe have used CHEMOSAT to treat patients with a variety of cancers in the liver, primarily ocular melanoma liver metastases, and other tumor types, including cutaneous melanoma, hepatocellular carcinoma, cholangiocarcinoma, and liver metastases from colorectal cancer, breast, pancreatic and neuroendocrine. In 2017, we announced our first patient to receive eight CHEMOSAT treatments, and have seen the average number of repeat treatments performed on a per patient basis consistently increase.

European Reimbursement

A critical driver of utilization growth for CHEMOSAT in Europe is the expansion of reimbursement mechanisms for the procedure in our priority markets. In Europe, there is no centralizedpan-European medical device

reimbursement body. Reimbursement is administered on a regional and national basis. Medical devices are typically reimbursed under Diagnosis Related Groups (“DRG”) as part of a procedure. Prior to obtaining permanent DRG reimbursement codes, in certain jurisdictions, we are actively seeking interim reimbursement from existing mechanisms that include specific interim reimbursement schemes, new technology payment programs as well as existing DRG codes. In most EU countries, the government provides healthcare and controls reimbursement levels. Since the EU has no jurisdiction over patient reimbursement or pricing matters in its member states, the methodologies for determining reimbursement rates and the actual rates may vary by country.

Effective with the execution of our license agreement with medac, medac will provide support for reimbursement applications in the European markets covered by our agreement.

Germany

In October 2015, we announced that the Institut für das Entgeltsystem im Krankenhaus (InEk), the German federal reimbursement agency, established a national Zusatzentgeld (ZE) reimbursement code for procedures performed with CHEMOSAT in Germany. The ZE diagnostic-related group (DRG) code is a national reimbursement code that augments existing DRG codes until a specific new DRG code can be created and will replace the previous Neue Untersuchungs und Behandlungsmethoden (NUB) procedure that required patients in Germany to apply individually for reimbursement of their CHEMOSAT treatment. With the establishment of a ZE code for CHEMOSAT, the procedure is now permanently represented in the DRG catalog in Germany. Coverage levels under this process are negotiated between hospitals in Germany and regional sickness funds, with coverage levels renegotiated annually. In 2018 CHEMOSAT was added to the German national treatment guidelines for liver metastases from melanoma. Inclusion in these guidelines is an important step towards a fixed DRG code for CHEMOSAT in Germany.

United Kingdom

In May 2014, the National Institute for Clinical Excellence (“NICE”), anon-departmental public body that provides guidance and advice to improve health and social care in the UK, completed a clinical review of CHEMOSAT. The NICE review indicated that as the current body of evidence on the safety and efficacy of PHP with CHEMOSAT for primary or metastatic liver cancer is limited, the procedure should be performed within the context of research by clinicians with specific training in its use and techniques. Delcath expects to consult again with the Interventional Procedures Advisory Committee at NICE in England, to provide recent clinical evidence with a view to moving existing Interventional Procedural Guidance from research to specialist status. medac will continue consultations begun by Delcath with the Interventional Procedures Advisory Committee at NICE in England, providing recent clinical evidence with a view to moving existing Interventional Procedural Guidance from a research recommendation to specialist recommendation. This would enable greater scope for commercialization access to the therapy because it would allow more use by National Health Service (“NHS”) clinicians of the therapy. It might also pave the way for a full Medical Technology Assessment as a way towards longer term reimbursement within the NHS.

In the short term, public patients will continue to be treated in the UK through clinical trials. Private patients will continue to be treated through the established private treatment pathway such as private insurance coverage orself-pay.

Netherlands

In the Netherlands CHEMOSAT has been performed at the Netherlands Cancer Institute in 2013 and at Leiden University Medical Centre since 2014. In June 2017 the Medical Oncology National Treatment Guidelines for Uveal Melanoma were updated and now include recommendations to consider CHEMOSAT in the treatment of liver metastases. We are hopeful that inclusion in the national guidelines and the support of clinicians treating patients with CHEMOSAT will support an application for reimbursement in this market.

Regulatory Status

Our products are subject to extensive and rigorous government regulation by foreign regulatory agencies and the FDA. Foreign regulatory agencies, the FDA and comparable regulatory agencies in state and local jurisdictions impose extensive requirements upon the clinical development,pre-market clearance and approval, manufacturing, labeling, marketing, advertising and promotion, pricing, storage and distribution of pharmaceutical and medical device products. Failure to comply with applicable foreign regulatory agency or FDA requirements may result in Warning Letters, fines, civil or criminal penalties, suspension or delays in clinical development, recall or seizure of products, partial or total suspension of production or withdrawal of a product from the market.

United States Regulatory Environment

In the United States, the FDA regulates drug and device products under the FFDCA, and its implementing regulations. The Delcath Melphalan/HDS is subject to regulation as a combination product, which means it is composed of both a drug product and device product. If marketed individually, each component would therefore be subject to different regulatory pathways and reviewed by different centers within the FDA. A combination product, however, is assigned to a center that will have primary jurisdiction over itspre-market review and regulation based on a determination of its primary mode of action, which is the single mode of action that provides the most important therapeutic action. In the case of the Melphalan/HDS, the primary mode of action is attributable to the drug component of the product, which means that the Center for Drug Evaluation and Research, has primary jurisdiction over itspre-market development and review.

The process required by the FDA before drug product candidates may be marketed in the United States generally involves the following:

•

submission to the FDA of an IND, which must become effective before human clinical trials may begin and must be updated periodically, but at least annually;

•

completion of extensive preclinical laboratory tests and preclinical animal studies, all performed in accordance with the FDA’s Good Laboratory Practice, or GLP, regulations;

•

performance of adequate and well-controlled human clinical trials to establish the safety and efficacy of the product candidate for each proposed indication;

•

submission to the FDA of an NDA after completion of all pivotal clinical trials;

•

a determination by the FDA within 60 days of its receipt of an NDA to file the NDA for review;

•

satisfactory completion of an FDApre-approval inspection of the manufacturing facilities at which the product is produced and tested to assess compliance with current good manufacturing practice, or cGMP, regulations; and

•

FDA review and approval of an NDA prior to any commercial marketing or sale of the drug in the United States.

The development and approval process requires substantial time, effort and financial resources, and we cannot be certain that any approvals for our product will be granted on a timely basis, if at all.

The results of preclinical tests (which include laboratory evaluation as well as GLP studies to evaluate toxicity in animals) for a particular product candidate, together with related manufacturing information and analytical data, are submitted as part of an IND to the FDA. The IND automatically becomes effective 30 days after receipt by the FDA, unless the FDA, within the30-day time period, raises concerns or questions about the conduct of the proposed clinical trial, including concerns that human research subjects will be exposed to unreasonable health risks. In such a case, the IND sponsor and the FDA must resolve any outstanding concerns before the clinical trial can begin. IND submissions may not result in FDA authorization to commence a clinical trial. A separate

submission to an existing IND must also be made for each successive clinical trial conducted during product development. Further, an independent institutional review board, or IRB, for each medical center proposing to conduct the clinical trial must review and approve the plan for any clinical trial before it commences at that center and it must monitor the study until completed. The FDA, the IRB or the sponsor may suspend a clinical trial at any time on various grounds, including a finding that the subjects or patients are being exposed to an unacceptable health risk. Clinical testing also must satisfy extensive good clinical practice regulations and regulations for informed consent and privacy of individually identifiable information. Similar requirements to the United States IND are required in the European Economic Area and other jurisdictions in which we may conduct clinical trials.

Clinical Trials

For purposes of NDA submission and approval, clinical trials are typically conducted in the following sequential phases, which may overlap:

•

Phase 1 Clinical Trials. Studies are initially conducted in a limited population to test the product candidate for safety, dose tolerance, absorption, distribution, metabolism and excretion, typically in healthy humans, but in some cases in patients.

•

Phase 2 Clinical Trials. Studies are generally conducted in a limited patient population to identify possible adverse effects and safety risks, explore the initial efficacy of the product for specific targeted indications and to determine dose range or pharmacodynamics. Multiple Phase 2 clinical trials may be conducted by the sponsor to obtain information prior to beginning larger and more expensive Phase 3 clinical trials.

•

Phase 3 Clinical Trials. These are commonly referred to as pivotal studies. When Phase 2 evaluations demonstrate that a dose range of the product is effective and has an acceptable safety profile, Phase 3 clinical trials are undertaken in large patient populations to further evaluate dosage, provide substantial evidence of clinical efficacy and further test for safety in an expanded and diverse patient population at multiple, geographically dispersed clinical trial centers.

•

Phase 4 Clinical Trials. The FDA may approve an NDA for a product candidate, but require that the sponsor conduct additional clinical trials to further assess the drug after NDA approval under a post-approval commitment. In addition, a sponsor may decide to conduct additional clinical trials after the FDA has approved an NDA. Post-approval trials are typically referred to as Phase 4 clinical trials.

Sponsors of clinical trials may submit proposals for the design, execution, and analysis for their pivotal trials under a SPA. A SPA is an evaluation by the FDA of a protocol with the goal of reaching an agreement that the Phase 3 trial protocol design, clinical endpoints, and statistical analyses are acceptable to support regulatory approval of the drug product candidate with respect to effectiveness for the indication studied. Under a SPA, the FDA agrees to not later alter its position with respect to adequacy of the design, execution or analyses of the clinical trial intended to form the primary basis of an effectiveness claim in an NDA, without the sponsor’s agreement, unless the FDA identifies a substantial scientific issue essential to determining the safety or efficacy of the drug after testing begins.

Prior to initiating our currently ongoing Phase 3 clinical trial(s), we submitted a proposal for the design, execution and analysis under a SPA.

New Drug Applications

The results of drug development, preclinical studies and clinical trials are submitted to the FDA as part of an NDA. NDAs also must contain extensive chemistry, manufacturing and control information. An NDA must be accompanied by a significant user fee, which may be waived in certain circumstances. Once the submission has been accepted for filing, the FDA’s goal is to review applications within ten months of submission or, if the

application relates to an unmet medical need in a serious or life-threatening indication, six months from submission. The review process is often significantly extended by FDA requests for additional information or clarification. The FDA may refer the application to an advisory committee for review, evaluation and recommendation as to whether the application should be approved. For new oncology products, the FDA will often solicit an opinion from an ODAC, a panel of expert authorities knowledgeable in the fields of general oncology, pediatric oncology, hematologic oncology, immunologic oncology, biostatistics, and other related professions. The ODAC panel reviews and evaluates data concerning the safety and effectiveness of marketed and investigational human drug products for use in the treatment of cancer, and makes appropriate recommendations to the Commissioner of Food and Drugs. The FDA is not bound by the recommendation of an advisory committee. The FDA may deny approval of an NDA by issuing a Complete Response Letter (CRL) if the applicable regulatory criteria are not satisfied. A CRL may require additional clinical data and/or an additional pivotal Phase 3 clinical trial(s), and/or other significant, expensive and time-consuming requirements related to clinical trials, preclinical studies or manufacturing. Data from clinical trials are not always conclusive and the FDA may interpret data differently than we or our collaborators interpret data. Approval may be contingent on a Risk Evaluation and Mitigation Strategy (REMS) that limits the labeling, distribution or promotion of a drug product. Once issued, the FDA may withdraw product approval if ongoing regulatory requirements are not met or if safety problems occur after the product reaches the market. In addition, the FDA may require testing, including Phase IV clinical trials, and surveillance programs to monitor the safety effects of approved products which have been commercialized, and the FDA has the power to prevent or limit further marketing of a product based on the results of these post-marketing programs or other information.

There are three primary regulatory pathways for a New Drug Application under Section 505 of the FFDCA: Section 505 (b)(1), Section 505 (b)(2) and Section 505(j). A Section 505 (b)(1) application is used for approval of a new drug (for clinical use) whose active ingredients have not been previously approved. A Section 505 (b)(2) application is used for a new drug that relies on data not developed by the applicant. Section 505(b)(2) of the FFDCA was enacted as part of the Drug Price Competition and Patent Term Restoration Act of 1984, also known as the Hatch-Waxman Act. This statutory provision permits the approval of an NDA where at least some of the information required for approval comes from studies not conducted by or for the applicant and for which the applicant has not obtained a right of reference. The Hatch-Waxman Act permits the applicant to rely in part upon the FDA’s findings of safety and effectiveness for previously approved products. Section 505(j) application, also known as an abbreviated NDA, is used for a generic version of a drug that has already been approved.

Orphan Drug Exclusivity

Some jurisdictions, including the United States, may designate drugs for relatively small patient populations as orphan drugs. Pursuant to the Orphan Drug Act, the FDA grants orphan drug designation to drugs intended to treat a rare disease or condition, which is generally a disease or condition that affects fewer than 200,000 individuals in the United States. The orphan designation is granted for a combination of a drug entity and an indication and therefore it can be granted for an existing drug with a new (orphan) indication. Applications are made to the Office of Orphan Products Development at the FDA and a decision or request for more information is rendered in 60 days. NDAs for designated orphan drugs are exempt from user fees, obtain additional clinical protocol assistance, are eligible for tax credits up to 50% of research and development costs, and are granted a seven-year period of exclusivity upon approval. The FDA cannot approve the same drug for the same condition during this period of exclusivity, except in certain circumstances where a new product demonstrates superiority to the original treatment. Exclusivity begins on the date that the marketing application is approved by the FDA for the designated orphan drug, and an orphan designation does not limit the use of that drug in other applications outside the approved designation in either a commercial or investigational setting.

The FDA has granted Delcath six orphan drug designations. In November 2008, the FDA granted Delcath two orphan drug designations for the drug melphalan for the treatment of patients with cutaneous melanoma, as well as patients with ocular melanoma. In May 2009, the FDA granted Delcath an additional orphan drug designation

of the drug melphalan for the treatment of patients with neuroendocrine tumors. In August 2009, the FDA granted Delcath an orphan drug designation of the drug doxorubicin for the treatment of patients with primary liver cancer. In October 2013, the FDA granted Delcath an orphan drug designation of the drug melphalan for the treatment of HCC. In July 2015, the FDA granted Delcath an orphan drug designation of the drug melphalan for the treatment of cholangiocarcinoma, which includes ICC.

The granting of orphan drug designations does not mean that the FDA has approved a new drug. Companies must still pursue the rigorous development and approval process that requires substantial time, effort and financial resources, and we cannot be certain that any approvals for our product will be granted at all, or on a timely basis.

Intellectual Property and Other Rights

Our success depends in part on our ability to obtain patents and trademarks, maintain trade secret andknow-how protection, enforce our proprietary rights against infringers, and operate without infringing on the proprietary rights of third parties. Because of the length of time and expense associated with developing new products and bringing them through the regulatory approval process, the health care industry places considerable emphasis on obtaining patent protection and maintaining trade secret protection for new technologies, products, processes,know-how, and methods. The Company currently holds rights in eight U.S. utility patents, one U.S. design patent, five pending U.S. utility patent applications, six issued foreign counterpart utility patents (including the validation of a European patent directed to our filter apparatus in eight European countries, six issued foreign counterpart design patents, and eight pending foreign counterpart patent applications. In July 2017, a patent directed to our chemotherapy filtration system was issued by the U.S. Patent and Trademark Office. In October 2018 and February 2019 patents directed to our chemotherapy filtration system and a method of using our filter and frame apparatus were issued by the United States Patent and Trademark Office. A Notice of Allowance was obtained from the United States Patent and Trademark Office for the patent application entitled “Apparatus For Removing Chemotherapy Compounds from Blood” with allowed claims to a kit of parts capable of being assembled for delivering a small molecule chemotherapeutic agent to a subject. The allowed claims are directed to CHEMOSAT. A Hong Kong patent directed to our Filter and Frame Apparatus was issued in March of 2018. A European patent was granted for our chemotherapy filtration system in November 2018 and a European patent application directed to a method of using our filter and frame apparatus was granted in April 2019 by the European Patent Office.

When appropriate, the Company actively pursues protection of our proprietary products, technologies, processes, and methods by filing United States and international patent and trademark applications. We seek to pursue additional patent protection for technology invented through research and development, manufacturing, and clinical use of the CHEMOSAT and Melphalan/HDS that will enable us to expand our patent portfolio around advances to our current systems, technology, and methods for our current applications as well as beyond the treatment of cancers in the liver.

There can be no assurance that the pending patent applications will result in the issuance of patents, that patents issued to or licensed by us will not be challenged or circumvented by competitors, or that these patents will be found to be valid or sufficiently broad to protect our technology or provide us with a competitive advantage.

To maintain our proprietary position, we also rely on trade secrets and proprietary technological experience to protect proprietary manufacturing processes, technology, andknow-how relating to our business. We rely, in part, on confidentiality agreements with our marketing partners, employees, advisors, vendors and consultants to protect our trade secrets and proprietary technological expertise. In addition, we also seek to maintain our trade secrets through maintenance of the physical security of the premises where our trade secrets are located. There can be no assurance that these agreements will not be breached, that we will have adequate remedies for any breach, that others will not independently develop equivalent proprietary information or that third parties will not otherwise gain access to our trade secrets and proprietary knowledge.

In certain circumstances, United States patent law allows for the extension of a patent’s duration for a period of up to five years after FDA approval. The Company intends to seek extension for one of our patents after FDA approval if it has not expired prior to the date of approval. In addition to our proprietary protections, the FDA has granted Delcath five orphan drug designations that provide us a seven-year period of exclusive marketing beginning on the date that our NDA is approved by the FDA for the designated orphan drug. While the exclusivity only applies to the indication for which the drug has been approved, the Company believes that it will provide us with added protection once commercialization of an orphan drug designated product begins.

There has been and continues to be substantial litigation regarding patent and other intellectual property rights in the pharmaceutical and medical device areas. If a third party asserts a claim against Delcath, the Company may be forced to expend significant time and money defending such actions and an adverse determination in any patent litigation could subject us to significant liabilities to third parties, require us to redesign our product, require us to seek licenses from third parties, and, if licenses are not available, prevent us from manufacturing, selling or using our system. Additionally, Delcath plans to enforce its intellectual property rights vigorously and may find it necessary to initiate litigation to enforce our patent rights or to protect our trade secrets orknow-how. Patent litigation can be costly and time consuming and there can be no assurance that the outcome will be favorable to us.

Other Regulatory Requirements

Products manufactured or distributed pursuant to FDA approvals are subject to continuing regulation by the FDA, including recordkeeping, annual product quality review and reporting requirements. Adverse event experience with the product must be reported to the FDA in a timely fashion and pharmacovigilance programs to proactively look for these adverse events are mandated by the FDA. Drug manufacturers and their subcontractors are required to register their establishments with the FDA and certain state agencies, and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with ongoing regulatory requirements, including cGMPs, which impose certain procedural and documentation requirements upon us and our third-party manufacturers. Following such inspections, the FDA may issue notices on Form 483 and Untitled Letters or Warning Letters that could cause us or our third-party manufacturers to modify certain activities. A Form 483 Notice, if issued at the conclusion of an FDA inspection, can list conditions the FDA investigators believe may have violated cGMP or other FDA regulations or guidelines. In addition to Form 483 Notices and Untitled Letters or Warning Letters, failure to comply with the statutory and regulatory requirements can subject a manufacturer to possible legal or regulatory action, such as suspension of manufacturing, seizure of product, injunctive action or possible civil penalties. We cannot be certain that we or our present or future third-party manufacturers or suppliers will be able to comply with the cGMP regulations and other ongoing FDA regulatory requirements. If we or our present or future third-party manufacturers or suppliers are not able to comply with these requirements, the FDA may require us to recall our products from distribution or withdraw any potential approvals of an NDA for that product.

Physicians may prescribe legally available products for uses that are not described in the product’s labeling and that differ from those tested by us and approved by the FDA. Suchoff-label uses are common across medical specialties, in particular in oncology. Physicians may believe that suchoff-label uses are the best treatment for many patients in varied circumstances. The FDA does not regulate the behavior of physicians in their choice of treatments. The FDA does, however, impose stringent restrictions on manufacturers’ communications regardingoff-label use.

European Regulatory Environment

In the EEA, the CHEMOSAT system is subject to regulation as a medical device. The EEA is composed of the 27 Member States of the EU plus Norway, Iceland and Liechtenstein. Under the EU Medical Devices Directive (Directive No 93/42/ECC of 14 June 1993, as last amended), drug delivery products such as the CHEMOSAT system is governed by the EU laws on pharmaceutical products only if they are (i) placed on the market in such a way that the device and the pharmaceutical product form a single integral unit which is intended exclusively for use in the given combination, and (ii) the product is not reusable. In such cases, the drug delivery product is governed by the EU Code on Medicinal Products for Human Use (Directive 2001/83/EC, as last amended), while the essential requirements of the EU Medical Devices Directive apply to the safety and performance-related device features of the product. Because we do not intend to place the CHEMOSAT system on the EEA market as a single integral unit with melphalan, the product is governed solely by the EU Medical Devices Directive, while the separately marketed drug is governed by the EU Code relating to Medicinal Products for Human Use and other EU legislation applicable to drugs for human use.

Before we may commercialize a medical device in the EEA, we must comply with the essential requirements of the EU Medical Devices Directive. Compliance with these requirements entitles a manufacturer to affix a CE conformity mark, without which the products cannot be commercialized in the EEA. To demonstrate compliance with the essential requirements and obtain the right to affix the CE conformity mark, medical device manufacturers must undergo a conformity assessment procedure, which varies according to the type of medical device and its classification. In April 2011, we obtained authorization to affix a CE Mark for the Generation One CHEMOSAT system and began European commercialization with this version of the CHEMOSAT system in early 2012. In April 2012, the Company obtained authorization to affix a CE Mark for the Generation Two CHEMOSAT system, and since this time all procedures in Europe have been performed with this version of the system.

The Medical Devices Directive establishes a classification system placing devices into Class I, IIa, IIb, or III, depending on the risks and characteristics of the medical device. For certain types of low risk medical devices (i.e., Class I devices which arenon-sterile and do not have a measuring function), the manufacturer may issue an EC Declaration of Conformity based on a self-assessment of the conformity of its products with the essential requirements of the EU Medical Devices Directives. Other devices are subject to a conformity assessment procedure requiring the intervention of a Notified Body, which is an organization designated by a Member State of the EEA to conduct conformity assessments.

CHEMOSAT is regulated as a Class IIb medical device. As a Class IIb medical device, the Notified Body is not required to carry out an examination of the product’s design dossier as part of its conformity assessment prior to commercialization. The Company must continue to comply with the essential requirements of the EU Medical Devices Directive (Directive 93/42 EC) and is subject to a conformity assessment procedure requiring the intervention of a Notified Body. The conformity assessment procedure for Class IIb medical devices requires the manufacturer to apply for the assessment of its quality system for the design, manufacture and inspection of its medical devices by a Notified Body. The Notified Body will audit the system to determine whether it conforms to the provisions of the Medical Devices Directive. If the Notified Body’s assessment is favorable, it will issue a Full Quality Assurance Certificate, which enables the manufacturer to draw a Declaration of Conformity and affix the CE mark to the medical devices covered by the assessment. Thereafter, the Notified Body will carry out periodic audits to ensure that the approved quality system is applied by the manufacturer.

A manufacturer without a registered place of business in a Member State of the EU which places a medical device on the market under its own name must designate an Authorized Representative established in the European Union who can act before, and be addressed by, the Competent Authorities on the manufacturer’s behalf with regard to the manufacturer’s obligations under the EU Medical Devices Directive. We appointed such a representative prior to establishing our infrastructure in the EEA. With the Delcath Systems Ltd. infrastructure now firmly in place, the Authorized Representative responsibilities have been formally transferred internally and there is no longer a need for a third-party representative.

In the EEA, we must also comply with the Medical Device Vigilance System, which is designed to improve the protection of health and safety of patients, users and others by reducing the likelihood of recurrence of incidents related to the use of a medical device. Under this system, incidents are defined as any malfunction or deterioration in the characteristics and/or performance of a device, as well as any inadequacy in the labeling or the instructions for use which, directly or indirectly, might lead to or might have led to the death of a patient, or user or of other persons or to a serious deterioration in their state of health. When a medical device is suspected to be a contributory cause of an incident, its manufacturer or authorized representative in the EU must report it to the Competent Authority of the Member State where the incident occurred. Incidents are generally investigated by the manufacturer. The manufacturer’s investigation is monitored by the Competent Authority, which may intervene, or initiate an independent investigation if considered appropriate. An investigation may conclude in the adoption of a Field Safety Corrective Action (FSCA). An FSCA is an action taken by a manufacturer to reduce a risk of death or serious deterioration in the state of health associated with the use of a medical device that is already placed on the market. An FSCA may include device recall, modification exchange and destruction.

FSCAs must be notified by the manufacturer or its authorized representative to its customers and/or the end users of the medical device via a Field Safety Notice.

In the EEA, theoff-label promotion of a pharmaceutical product is strictly prohibited under the EU Community Code on Medicinal Products, which provides that all information provided within the context of the promotion of a drug must comply with the information contained in its approved summary of product characteristics. Our product instructions and indication reference the chemotherapeutic agent melphalan hydrochloride. However, no melphalan labels in the EEA reference our product, and the labels vary from country to country with respect to the approved indication of the drug and its mode of administration. In the exercise of their professional judgment in the practice of medicine, physicians are generally allowed, under certain conditions, to use or prescribe a product in ways not approved by regulatory authorities. Physicians intending to use our device must obtain melphalan separately for use with the CHEMOSAT system and must use melphalan independently at their discretion.

In the EEA, the advertising and promotion of our products is also subject to EEA Member States laws implementing the EU Medical Devices Directive, Directive 2006/114/EC concerning misleading and comparative advertising and Directive 2005/29/EC on unfair commercial practices, as well as other EEA Member State legislation governing the advertising and promotion of medical devices. These laws may further limit or restrict the advertising and promotion of our products to the general public and may also impose limitations on our promotional activities with health care professionals.

Failure to comply with the EEA Member State laws implementing the Medical Devices Directive, with the EU and EEA Member State laws on the promotion of medicinal products or with other applicable regulatory requirements can result in enforcement action by the EEA Member State authorities, which may include any of the following: fines, imprisonment, orders forfeiting products or prohibiting or suspending their supply to the market, or requiring the manufacturer to issue public warnings, or to conduct a product recall.

The European Commission recently reviewed the Medical Device Directive legislative framework and promulgated REGULATION (EU) 2017/745 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 5 April 2017 on medical devices, amending Directive 2001/83/EC, Regulation EC) No 178/2002 and Regulation (EC) No 1223/2009 and repealing Council Directives 90/385/EEC and 93/42/EEC. This new Medical Device Regulation became effective on May 25, 2017, marking the start of a3-year transition period for manufacturers selling medical device in Europe to comply with the new medical device regulation (“MDR”) which governs all facets of medical devices. The transition task is highly complex and touches every aspect of product development, manufacturing production, distribution and post marketing evaluation.

Effectively addressing these changes will require a complete review of our device operations to determine what is necessary to comply. We do not believe the MDR regulatory changes will impact our business at this time, though implementation of the medical device legislation may adversely affect our business, financial condition and results of operations or restrict our operations.

Other International Regulations

We continue to evaluate commercial opportunities in select markets when resources are available and at an appropriate time.

Competition

The healthcare industry is characterized by extensive research, rapid technological progress and significant competition from numerous healthcare companies and academic institutions. Competition in the cancer treatment industry is intense. We believe that the primary competitive factors for products addressing cancer include safety, efficacy, ease of use, reliability and price. We also believe that physician relationships, especially relationships

with leaders in the medical and surgical oncology communities, are important competitive factors. We also believe that the current global economic conditions and new healthcare reforms could put competitive pressure on us, including reduced selling prices and potential reimbursement rates, and overall procedure rates. Certain markets in Europe are experiencing the effects of continued economic weakness, which is affecting healthcare budgets and reimbursement.

CHEMOSAT and Melphalan/HDS competes with all forms of liver cancer treatments, including surgery, systemic chemotherapy, focal therapies and palliative care. In the disease states we are targeting there are also numerous clinical trials sponsored by third-parties, which can compete for potential patients in the near term and may ultimately lead to new competitive therapies.

For ocular melanoma liver metastases, there are currently no approved or effective treatment options, and patients are generally treated with a variety of focal and regional techniques. There are numerous companies developing and marketing devices for the performance of focal therapies, including Boston Scientific, Covidian, Merit, CeleNova, SirTex, AngioDynamics, and many others.

For ICC, gemcitabine plus cisplatin remains the standard of care for the treatment of ICC in patients who are not candidates for surgery.

Several therapies have been recently approved for unresectable or metastatic cutaneous melanoma, which may encompass liver metastases. Dabrafenib (Tafinlar^™, GlaxoSmithKline), is indicated as single agent for the treatment of patients with unresectable or metastatic melanoma with BRAF V600E mutation, and in combination with trametinib in unresectable or metastatic melanoma with BRAF V600E or V600K mutations. Furthermore, trametinib (MEKINIST^™, GlaxoSmithKline) is indicated as single agent (in addition to in combination with dabrafinib) for treatment of patients with unresectable or metastatic melanoma with BRAF V600E or V600K mutations. Previously approved melanoma therapies such as the biologic ipilimumab (Yervoy^™, Bristol Myers Squibb) and theB-RAF targeted drug vemurafenib (Zelboraf^™, Genentech) may also make up the competitive landscape for the treatment of metastatic liver disease.

Many of these treatments are approved in Europe and other global markets.

Many of our competitors have substantially greater financial, technological, research and development, marketing and personnel resources. In addition, some of our competitors have considerable experience in conducting clinical trials, regulatory, manufacturing and commercialization capabilities. Our competitors may develop alternative treatment methods, or achieve earlier product development, in which case the likelihood of us achieving meaningful revenues or profitability will be substantially reduced.

Manufacturing and Quality Assurance

We manufacture certain critical medical device components including our proprietary filter media and assemble and package the CHEMOSAT and Melphalan/HDS at our facility in Queensbury, New York. We have established our European headquarters and distribution facility in Galway, Ireland where we conduct final manufacturing, processing and assembly. Delcath currently utilizes third-parties to manufacture some components of the CHEMOSAT and Melphalan/HDS. The CHEMOSAT and Melphalan/HDS and its components must be manufactured and sterilized in accordance with approved manufacturing andpre-determined performance specifications. In addition, certain components will require sterilization prior to distribution and Delcath relies on third-party vendors to perform the sterilization process.

We are committed to providing high quality products to our customers. To honor this commitment, Delcath has implemented updated quality systems throughout our organization. Delcath’s quality system starts with the initial product specification and continues through the design of the product, component specification process and the manufacturing, sale and servicing of the product. These systems are designed to enable us to satisfy the various

international quality system regulations including those of the FDA with respect to products sold in the United States and those established by the International Standards Organization (ISO) with respect to products sold in the EEA. The Company is required to maintain ISO 13485 certification for medical devices to be sold in the EEA, which requires, among other items, an implemented quality system that applies to component quality, supplier control, product design and manufacturing operations. On February 17, 2011, we announced that we had achieved ISO 13485 certification for our Queensbury manufacturing facility. On December 28, 2011, we announced that we had achieved ISO 13485 certification for our Galway, Ireland facility. All Delcath manufacturing facilities are presently ISO 13485:2016 certified.

Recent Events

Amendments to Registration Rights Agreements

On September 30, 2019, the Company and holders of a majority of the Company’s Series E and SeriesE-1 Convertible Preferred Stock entered into an amendment to those certain registration rights agreements, dated as of July 11, 2019 (effective as of July 15, 2019) (the “July Registration Rights Agreement”) and August 15, 2019 (the “August Registration Rights Agreement”), between the Company and the holders signatory thereto (the “Amendment”). The Amendment extends the applicable deadline for having a registration statement declared effective by the Commission under certain circumstances from 75 days to 120 days following the date of the July Registration Rights Agreement.

On October 18, 2019, the Company and holders of a majority of the Company’s Series E and SeriesE-1 Convertible Preferred Stock entered into a second amendment (the “Second Amendment”) to those certain registration rights agreements, dated as of July 11, 2019 (effective as of July 15, 2019) and August 15, 2019, in each case as amended on September 30, 2019, between the Company and the holders signatory thereto. The Second Amendment eliminates the deadline to file apre-effective registration statement amendment within 10 days of the Company’s receipt of comments from the SEC.

On October 29, 2019, the Company and holders of a majority of the Company’s Series E and SeriesE-1 Convertible Preferred Stock and related warrants entered into a third amendment (the “Third Amendment”) to those certain registration rights agreements, dated as of July 11, 2019 (effective as of July 15, 2019) and August 15, 2019, in each case as previously amended on September 30, 2019 and October 18, 2019, between the Company and the holders signatory thereto (collectively, the “Registration Rights Agreements”). The Third Amendment clarifies that the liquidated damages specified in Section 2(d) of the Registration Rights Agreements shall not be payable to any holder whose Registrable Securities, as defined in the Registration Rights Agreements, are fully registered on an effective registration statement on the Effectiveness Date, as defined in the Registration Rights Agreements.

Waiver and Forbearance Agreement

Also on October 29, 2019, the Company entered into a Waiver and Forbearance Agreement (“Waiver”) with Rosalind Master Fund LP and Rosalind Opportunities Fund I LP, holders of its Series E and SeriesE-1 Convertible Preferred Stock and related warrants (together, “Rosalind”), pursuant to which Rosalind has agreed, among other things, to waive compliance with certain specified terms and conditions under the Registration Rights Agreements and forbear from exercising certain of their rights and remedies related to certain defaults thereunder for the time periods indicated therein.

Reverse Stock Split

approve and adopt an amendment to our Amended and Restated Certificate of Incorporation to effect a reverse stock split of our shares of common stock, $0.01 par value per share, issued and outstanding or reserved for issuance, at a specific ratio within a range from1-for-50 to1-for-1,200, inclusive, prior to the first anniversary of stockholder approval of the proposal, and to grant authorization to the Board of Directors to determine, in its sole discretion, whether to effect the reverse stock split, as well as its specific timing and ratio. Also on the same date, the Company’s Board of Directors adopted resolutions to effect as soon as reasonably practicable the reverse split of the issued and outstanding shares of the Common Stock at a ratio of1-for-100.

On October 17, 2019, the Company filed with the Secretary of State of the State of Delaware a Certificate of Amendment to the Company’s Amended and Restated Certificate of Incorporation (the “Charter Amendment”) to effect a reverse stock split of the issued and outstanding shares of the Company’s common stock, $0.01 par value per share, at a ratio of1-for-100 to be effective as of October 22, 2019 at 8:30 a.m., New York City time (the “Reverse Stock Split”). The Charter Amendment did not change the par value or any other terms of the common stock.

On October 22, 2019, the Company filed with the Secretary of State of the State of Delaware a Certificate of Correction (the “Certificate of Correction”) to the Charter Amendment, rescinding the Charter Amendment, citing an inaccuracy in Article Third of the Charter Amendment, which states an effective time for the Reverse Stock Split of 8:30 a.m. New York City time on October 22, 2019. Such effective time was based upon the Company’s prior receipt, on October 17, 2019, of confirmation by the Financial Industry Regulatory Authority, Inc. (“FINRA”) that it had completed its review of the Reverse Stock Split, including the effective time, whereupon the Company undertook to effect the Reverse Stock Split by filing the Charter Amendment. On the evening of October 21, 2019, subsequent to the Company’s filing of the Charter Amendment and issuance of a press release on October 18, 2019 announcing the confirmation by FINRA, FINRA notified the Company’s counsel that it was rescinding its prior confirmation. The Certificate of Correction further provides that the Company is currently awaiting FINRA confirmation.

Following FINRA’s completion of its review of the Company’s Reverse Stock Split, on December 24, 2019, the Company effected the Reverse Split. All owners of record of our Common Stock as of the open of the OTCQB market on December 24, 2019 received one issued and outstanding share of Delcath Common Stock in exchange for seven hundred outstanding shares of Delcath Common Stock. No fractional shares were issued in connected with the Reverse Split. All fractional shares created by the Reverse Split were rounded up to the next whole share. The Reverse Split had no impact on the par value per share of Delcath Common Stock, which remains at $0.01. All current and prior period amounts related to shares, share prices and earnings per share, presented in the Company’s consolidated financial statements and the accompanying Notes have been restated to give retrospective presentation for the Reverse Split.

We were formed as a Delaware corporation in 1988. We maintain a public internet site at www.delcath.com. The information on our website does not constitute a part of, and is not incorporated in, this prospectus.

Employees

As of January 3, 2020, we had approximately 30 full time employees located in the United States and in Europe. None of our employees are represented by a labor union or covered by a collective bargaining agreement. We believe our relationship with our employees is good.

Executive Compensation.

Our Compensation Committee is responsible for formulating and establishing our overall compensation philosophy with respect to our executive officers. The Company believes that a strong executive management team comprised of talented individuals in key positions at the Company is critical to the development and growth of our business and to increasing stockholder value. Accordingly, a key objective of executive compensation is to attract and retain talented and experienced individuals, while motivating them to perform and make decisions consistent with the Company’s business objectives, goals and culture. We emphasizepay-for-performance by linking executive compensation to Company performance. For each executive, the amount of pay that is actually realized is primarily driven by the Company’s performance and each executive’s contribution to that performance.

Our Compensation Committee considers the input it receives from our stockholders when designing and evaluating our executive compensation practices.Compensation Components. The three primary components of executive compensation are base salary, annual incentive cash awards and long-term equity incentive awards:

•

Base Salary. We pay our executive officers a base salary, which our Compensation Committee reviews and determines annually. Base salaries are used to compensate our executive officers for performing the core responsibilities of their positions and to provide them with a level of security with respect to a portion of their total compensation. Base salaries are set in part based on the executive’s unique skills, experience and expected contribution to the Company, as well as individual performance, including the impact of such performance on our business results, and the period of the executive’s performance. Decisions regarding base salary increases take into account the executive’s current base salary, third-party benchmark and survey data, and the salary compensation paid to executive officers within and outside the Company, as well as the Company’s overall performance, its ability to afford such increases, its success in achieving its operational and strategic goals and objectives, and the executive officer’s contribution to Company performance.

•

Annual Incentive Cash Awards. Annual incentive compensation is intended to establish a direct correlation between annual cash awards and the performance of the Company. The Company’s Annual Incentive Plan (“AIP”) is an annual incentive cash bonus plan designed to align the interests of participants with the interests of the Company and its stockholders. The AIP is designed to strengthen the link between a participant’s pay and his or her overall performance and the Company’s performance, focus participants on critical individual and corporate objectives, offer a competitive cash incentive, and encourage and reward performance and competencies critical to the Company’s success.

•

Long-Term Incentive Compensation. In addition to using base salaries and annual incentive cash bonuses, which our Compensation Committee views as short-term compensation, a portion of our executive compensation is in the form of long-term equity compensation. Our Long-Term Incentive Plan (“LTIP”) is an annual equity-based incentive plan designed to align participants’ interests with those of the Company and its stockholders by rewarding participants for their contributions to the long-term success of the Company. The LTIP is designed to incentivize Company leaders to focus on the long-term performance of the Company, offer participants competitive, market-based long-term incentive award opportunities, and strengthen the link between a participant’s compensation and his or her overall performance and the Company’s overall long-term performance. We believe the LTIP assists us in achieving an appropriate balance between short- and long-term executive compensation.

Base Salary. The following table summarizes the amount of base salary and year-over-year increase for each of our named executive officers for 2018 and 2019:


Executive	Hire Date		2017 Base Salary		Percent Increase in 2018			2018 Base Salary		Percent Increase in 2019			2019 Base Salary
Jennifer K. Simpson, Ph.D.		3/23/2012	$	453,004		3.0	%	$	466,594		0	%	$	466,594
Barbra C. Keck, M.B.A.		1/5/2009	$	300,000		8.0	%	$	324,000		0	%	$	324,000
John Purpura, M.S.		11/16/2009	$	316,210		5.9	%	$	335,000		0	%	$	335,000

Annual Incentive Plan. Under the AIP, annual incentive target award opportunities are expressed as a percentage of a participant’s actual base salary for the performance year, beginning January 1. The following table sets forth, for each executive, the applicable target bonus percentage of base salary to which each executive is entitled. No annual bonus has been awarded or paid to any named executive officer for 2019.


Executive	Target Bonus Expressed as % of Base Salary			Dollars ($)		Actual Payout as % of Base Salary		Dollars ($)
Jennifer K. Simpson, Ph.D.		50.0	%	$	233,297		*	$	*
Barbra C. Keck, M.B.A.		45.0	%	$	145,800		*	$	*
John Purpura, M.S.		45.0	%	$	150,750		*	$	*

*	The annual bonus for 2019 is not calculable as of the filing date. The Company expects the annual bonus for 2019 will be calculable by March 15, 2020.

For 2019, AIP goals were based entirely on Company performance to focus all the executives on the same critical challenges facing the Company. Company performance in 2019 will be measured based upon achievement of objectives in the following areas: (1) Clinical Trials and (2) Capital. The Board is reviewing the Company’s performance for 2019 and no decisions have been made at this time.

Long Term Incentive Plan. Grants under the LTIP are typically comprised of a mix of restricted stock and stock option awards granted in the first quarter of each year with the number of shares subject to the awards designed to deliver a competitive valuetargeted at the mid-market of the executive compensation comparison group.

These guidelines are reviewed periodically based on prevailing compensation comparison group levels, however, and the Compensation Committee then uses these guidelines to determine long-term equity incentive awards for our named executive officers based upon a holistic assessment of Company and individual performance for the prior year and its view of the appropriate incentives to best help achieve the Company’s business objectives. Our ability to provideawards at the mid-market level has been difficult to do in the past few years due to share availability. Such awards in the past few years have typically been at or below the market 25th percentile.

Summary Compensation Table.

The following table sets forth the total compensation awarded to, earned by or paid to: (i) each person who served as a principal executive officer during 2019, and (ii) our two other most highly-compensated executive officers who were serving as executive officers on December 31, 2019. We refer to these individuals as our “named executive officers.”

(3)

Due to the lack of available shares for issuance under the Company’s 2009 Stock Incentive Plan, the Board of Directors did not grant any long-term equity awards to our named executive officers in 2018 which in no way should create any negative inference concerning the Compensation Committee’s evaluation of their performance.

Corporate Governance

Board of Directors. We have currently have five directors serving on the Board of Directors. The Board of Directors oversees the business affairs of the Company and monitors the performance of management. In accordance with our corporate governance principles, our Board does not involve itselfin day-to-day operations. The directors keep themselves informed through discussions with the Chairman of the Board, Roger G. Stoll, Jennifer K. Simpson, in her capacity as Director and Chief Executive Officer, or CEO, and other key executives, and by reading the reports and other materials that management sends them and by participating in Board and committee meetings. Our directors hold office until their successors have been elected and qualified unless the director resigns or is removed or by reason of death or other cause is unable to serve in the capacity of director.

Board Independence. The Board has determined that four of our five directors (each of Roger G. Stoll, William D. Rueckert, John R. Sylvester and Marco Taglietti) are “independent” directors within the meaning of the NASDAQ listing rules.

Attendance. The Board of Directors met 19 times in 2019 (including regularly scheduled and special meetings). During 2018], each director attended at least 75% of the aggregate of: (i) the total number of meetings of the Board (held during the period for which he or she served as a director) and (ii) the total number of meetings held by all committees of the Board of Directors on which he or she served (held during the period that he or she served). It is Delcath’s policy that, absent unusual or unforeseen circumstances, all directors are expected to attend annual meetings of stockholders.

Board Leadership Structure. Roger G. Stoll, Ph.D. was appointed Executive Chairman effective September 2014 and designated Chairman in connection with the appointment of Dr. Simpson as director effective October 2015. Dr. Stoll has been a member of the Board of Directors since 2008.

It is our policy to separate the Chairman and Chief Executive Officer roles. We believe this structure is appropriate for Delcath because it allows our President and CEO to concentrate onDelcath’s day-to-day operations, while providing for effective oversight by the Chairman, who is involved in strategic and key matters, such as business strategy, major transactions and the broader business of Delcath. For a company like Delcath that is focused on the development, approval and commercialization of a specialized product in an extremely technical, highly regulated and intensely competitive industry, we believe our President and CEO is in the best position to lead our management team, in part because of the depth of her experience in conducting clinical trials in oncology, and to respond to the current pressures and needs of a company in the stage of growth and development of Delcath, with assistance from our Chairman who also focuses the Board’s attention on the broader issues of corporate business strategy and corporate governance. We believe that splitting the roles between Chairman, on the one hand, and President and CEO, on the other hand, minimizes any potential conflicts that may result from combining the roles of CEO, President and Chairman, and maximizes the effectiveness of our management and governance processes to the benefit of our stockholders. Our President and CEO and Chairman regularly consult with each other as part of this structure.

Board’s Role in Risk Oversight. The Board as a whole is responsible for risk oversight, with reviews in certain areas being conducted by the relevant Board committees. Each of the Board’s committees oversees the management of risks associated with their respective areas of responsibility. In performing this oversight function, the committees are assisted by management which provides visibility about the identification, assessment and monitoring of potential risks and management’s strategy to mitigate such risks. Key members of management responsible for a particular area report directly to the Board committee charged with oversight of the associated function and, if the circumstances require, the whole Board. The Board committees review various risk exposures with the full Board and otherwise keep the full Board abreast of the committees’ risk oversight activities throughout the year, as necessary or appropriate.

Risk Assessment of Compensation Programs. Our Compensation and Stock Option Committee annually evaluates whether our compensation programs encourage excessive risk-taking by employees at the expense of

long-term Company value. Based upon its assessment, including a review of the overall annual award limitations and individual annual limitations in the Company’s stock incentive plans and the Compensation Committee’s role in the consideration and approval of certain awards, the Compensation and Stock Option Committee does not believe that our compensation programs encourage excessive or inappropriate risk-taking, motivate imprudent risk-taking or create risks that are reasonably likely to have a material adverse effect on the Company.

Board Committees. Our Board has three standing committees: an Audit Committee, a Compensation and Stock Option Committee and a Nominating and Corporate Governance Committee. No individual director is the chairman of more than one committee. Mr. Sylvester joined the board in July 2019 and has not been appointed to any committee yet.

Audit Committee. The Audit Committee provides assistance to the Board in fulfilling its oversight responsibilities with respect to the Company’s financial statements, the Company’s system of internal accounting and financial controls and the independent audit of the Company’s financial statements. Functions of the Audit Committee include:

•

the selection, evaluation and, where appropriate, replacement of our outside auditors;

•

an annual review and evaluation of the qualifications, performance and independence of our outside auditors;

•

the approval of all auditingservices and permitted non-audit services provided by our outside auditors;

•

the review of the adequacy and effectiveness of our accounting and internal controls over financial reporting; and

•

the review and discussion with management and with our outside auditors of the Company’s financial statements to be filed with the Commission.

The current members of the Audit Committee are William D. Rueckert (Chair), John Sylvester and Roger G. Stoll. The Board has determined that each of William D. Rueckert and Roger G. Stoll qualifies as an “audit committee financial expert” as defined by SEC rules. During 2019, the Audit Committee met four times. Each member of the Audit Committee is “independent” within the meaning of the NASDAQ listing rules and otherwise meets the financial statement proficiency requirements of the NASDAQ listing rules. The Audit Committee has a written charter, which is available on our website; go to www.delcath.com, click on “Investors,” then “Corporate Governance.”

Compensation and Stock Option Committee. The Compensation and Stock Option Committee (the “Compensation Committee”) assists the Board of Directors in the discharge of the Board’s responsibilities with respect to the compensation of Delcath’s directors, executive officers, and other key employees and consultants. The Compensation Committee establishes our overall compensation philosophy and is authorized to approve the compensation payable to our executive officers, including our named executive officers, and other key employees, including all perquisites, equity incentive awards, cash bonuses, and severance packages. The Compensation Committee also administers certain of the Company’s employee benefit plans, including its equity incentive plans, and is responsible for assessing the independence of compensation consultants and legal advisors. The Compensation Committee has concluded that McCarter & English, outside legal counsel to the Compensation Committee and the Company qualified as independent. The Compensation Committee exercises sole power to retain compensation consultants and advisors and to determine the scope of the associated engagements. The current members of the Compensation and Stock Option Committee are Marco Taglietti (Chair) and William D. Rueckert, and Roger G. Stoll, each of whom is “independent” within the meaning of NASDAQ listing rules. During 2019, the Compensation and Stock Option Committee met one time. The Compensation and Stock Option Committee has a written charter, which is available on our website; go to www.delcath.com, click on “Investors,” then “Corporate Governance.”

Nominating and Corporate Governance Committee. The Nominating and Corporate Governance Committee (the “Nominating Committee”) is responsible for identifying individuals qualified to become Board members, and

recommends to the Board the director nominees to be proposed by the Board for election by the stockholders (as well as any director nominees to be appointed by the Board to fill interim vacancies). The Nominating Committee also recommends the directors to be selected for membership on each Board committee.

The Nominating Committee is also responsible for developing and recommending to the Board appropriate corporate governance guidelines and policies, and for leading the Board in its annual review of the Board’s performance.

The current members of the Nominating Committee are Roger G. Stoll (Chairman), William D. Rueckert and Marco Taglietti, each of whom is “independent,” within the meaning of NASDAQ listing rules. During 2019, the Nominating Committee met two times. The Nominating Committee has a written charter, which is available on our website; go to www.delcath.com, click on “Investors,” then “Corporate Governance.”

The Nominating Committee, with, when it deems it necessary, the assistance of a third-party search firm, identifies candidates for director nominees. In considering candidates for the Board, the Nominating Committee considers each candidate’s credentials as a whole, including, but not necessarily limited to, outstanding achievement in a candidate’s personal career, broad and relevant experience, integrity, sound and independent judgment, experience and knowledge of the business environment and markets in which the Company operates, business acumen, and willingness and ability to devote adequate time to Board duties. The Nominating Committee considers the diversity of its members in the context of the Board as a whole, including the personal characteristics, experience and background of directors and nominees to facilitate Board deliberations that reflect a broad range of perspectives.

Recommendations by Stockholders of Director Nominees. The Nominating Committee will consider any recommendation by a stockholder of a candidate for nomination as a director. If a stockholder wants to recommend a director candidate for consideration by the Nominating Committee, the stockholder should submit the name of the proposed nominee, together with the reasons why the stockholder believes the election of the candidate would be beneficial to the Company and its stockholders and the information about the nominee that would be required in a proxy statement requesting proxies to vote in favor of the candidate. The stockholder’s submission must be accompanied by the written consent of the proposed nominee to being nominated by the Board and the candidate’s agreement to serve if nominated and elected. Any such submission should be directed to the Nominating Committee at Delcath’s principal office, 1633 Broadway, Suite 22C, New York, New York 10019. If a stockholder intends to nominate a person for election to the Board of Directors at an annual meeting, the stockholder must provide Delcath with written notice of his or her intention no later than the deadline for receiving a stockholder proposal for inclusion in Delcath’s proxy statement for such meeting and must otherwise comply with our amended and restated certificate of incorporation. Copies of any recommendation received in accordance with these procedures will be distributed to each member of the Nominating Committee. One or more members of the Nominating Committee may contact the proposed candidate to request additional information.

Stockholder Communications with the Board of Directors. Any stockholder wishing to communicate with the Board or with any specified director should address his or her communication to the Board of Directors or to the particular director(s) in care of the Corporate Secretary, Delcath Systems, Inc., 1633 Broadway, Suite 22C, New York, New York 10019. All such written communication, other than items determined by our legal counsel to be inappropriate for submission to the intended recipient(s), will be submitted to the Board or to the particular director(s). Any stockholder communication not so delivered, will be made available upon request to any director. Examples of stockholder communications that would be considered inappropriate for submission include, without limitation, customer complaints, business solicitations, product promotions, job inquiries, junk mail and mass mailings, as well as material that is unduly hostile, threatening, illegal or similarly unsuitable.

Compensation Committee Interlocks and Insider Participation. During 2019, Marco Taglietti, Roger G. Stoll and William D. Rueckert served as members of our Compensation and Stock Option Committee. None of the current members or members serving during 2019 of the Compensation and Stock Option Committee is a current or

former officer or employee of Delcath at the time of their service on the Compensation and Stock Option Committee, nor did any Compensation and Stock Option Committee member engage in any “related person” transaction that would be required to be disclosed underItem 404 of Regulation S-K. During 2019, none of Delcath’s executive officers served on the compensation committee (or equivalent) or on the board of directors of another entity whose executive officers served on the Compensation and Stock Option Committee or our Board of Directors.

Code of Ethics. We maintain a Code of Business Conduct and Ethics (Code) that applies to all employees, including our principal executive officer, principal financial officer, principal accounting officer, controller and persons performing similar functions, and including our independent directors, who are not employees of the Company, with regard to their Delcath-related activities. The Code incorporates guidelines designed to deter wrongdoing and to promote honest and ethical conduct and compliance with applicable laws, rules and regulations. The Code also incorporates our expectations of our employees that enable us to provide accurate and timely disclosure in our filings with the SEC and other public communications. In addition, the Code incorporates guidelines pertaining to topics such as complying with applicable laws, rules, and regulations; insider trading; reporting Code violations; and maintaining accountability for adherence to the Code. The full text of our Code is published on our website at http://delcath.com/investors/governance.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Transactions with Related Persons. We have adopted a written policy for the review and approval or ratification of transactions between Delcath and Related Parties (as defined below). Under the policy, our Nominating Committee will review the material facts of proposed transactions involving Delcath in which a Related Party will have a direct or indirect material interest. The Nominating Committee will either approve or disapprove Delcath’s entry into the transaction or, if advance approval is not feasible, will consider whether to ratify the transaction. The Nominating Committee may establish guidelines for ongoing transactions with a Related Party, and will review such transactions at least annually. If the aggregate amount of the transaction is expected to be less than $200,000, such approval or ratification may be made by the Chair of the Committee. In determining whether to approve or ratify a transaction with a Related Party, the Nominating Committee (or Chair) will consider, among other factors, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third-party and the extent of the Related Party’s interest in the transaction.

Certaintransactions are deemed pre-approved under the policy, including compensation of executive officers and directors (except that employment of an immediate family member of an executive officer requires specific approval), and transactions with a company at which the Related Party’s only relationship is as anon-officer employee, director, or less than 10% owner if the aggregate amount involved does not exceed 2% of such company’s total annual revenues (or, in the case of charitable contributions by Delcath, 2% of the charity’s total annual receipts).Pre-approval is not required if the amount involved in the transaction is not expected to exceed $120,000 in any calendar year.

For purposes of the policy, a Related Party is generally anyone who since the beginning of the last full fiscal year is or was an executive officer, director or director nominee, owner of more than 5% of the Common Stock, or immediate family member of any of such persons.

Except for the participation of certain Related Parties in the Private Placements and the Debt Exchange, no Related Party transactions occurred during 2019 and 2018.

Certain Anti-Takeover Provisions of Delaware Law and our Certificate of Incorporation and Bylaws

We are not subject to Section 203 of the Delaware General Corporation Law, which prohibits Delaware corporations from engaging in a wide range of specified transactions with any interested stockholder, defined to include, among others, any person other than such corporation and any of its majority owned subsidiaries who own 15% or more of any class or series of stock entitled to vote generally in the election of directors, unless, among other exceptions, the transaction is approved by (i) our board of directors prior to the date the interested stockholder obtained such status or (ii) the holders oftwo-thirds of the outstanding shares of each class or series of stock entitled to vote generally in the election of directors, not including those shares owned by the interested stockholder.

Staggered Board of Directors

Our certificateof incorporation and by-laws provide that our board of directors be classified into three classes of directors of approximately equal size. As a result, in most circumstances, a person can gain control of our board only by successfully engaging in a proxy contest at two or more annual meetings.

Authorized But Unissued Shares

Our authorized but unissued shares of preferred stock are available for future issuances without stockholder approval and could be utilized for a variety of corporate purposes, including future offerings to raise additional capital, corporate acquisitions, employee benefit plans and stockholder rights plans. The existence of authorized but unissued and unreserved preferred stock could render more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Each share of the Series E and SeriesE-1 Convertible Preferred Stock has a par value of $0.01 per share and a stated value equal to $1,000 (the “Stated Value”) and is convertible at any time at the option of the holder into the number of shares of Common Stock determined by dividing the stated value by the conversion price of $25.36, subject to certain limitations and adjustments (the “Conversion Price”). Except for certain adjustments, the holders of Series E and SeriesE-1 Convertible Preferred Stock will be entitled to receive dividends on shares of Series E and SeriesE-1 Convertible Preferred Stock equal (on an as if converted basis) to and in the same form as dividends paid on shares of the Common Stock. Any such dividends that are not paid to the holders of the Series E and SeriesE-1 Convertible Preferred Stock will increase the Stated Value. No other dividends will be paid on shares of Series E and SeriesE-1 Convertible Preferred Stock. The Series E and SeriesE-1 Convertible Preferred Stock will vote on an as converted basis on all matters submitted to the holders of Common Stock for approval, subject to certain limitations and exceptions. The affirmative vote of the holders of a majority of the then outstanding shares of the Series E and SeriesE-1 Convertible Preferred Stock is required to increase the number of authorized shares of Series E and SeriesE-1 Convertible Preferred Stock or to alter or change adversely the powers, preferences or rights given to the Series E and SeriesE-1 Convertible Preferred Stock, or to amend the Company’s organizational documents in any manner that adversely affects the rights of the holders of the Series E and SeriesE-1 Convertible Preferred Stock.

PLAN OF DISTRIBUTION

Each Selling Stockholder of the securities and any of their pledgees, assignees andsuccessors-in-interest may, from time to time, sell any or all of their securities covered hereby on the principal trading market (any of the markets or exchanges on which the Common Stock is listed or quoted for trading on the date in question: the NYSE American, the Nasdaq Capital Market, the Nasdaq Global Market, the Nasdaq Global Select Market, the New York Stock Exchange, OTCQB or OTC QX (or any successors to any of the foregoing)) or in private transactions. These sales may be at fixed or negotiated prices. The Company will not receive any of the proceeds from the sale by the Selling Stockholders of the securities. A Selling Stockholder may use any one or more of the following methods when selling securities:

•

ordinary brokerage transactions and transactions in which the broker-dealer solicits purchasers;

•

block trades in which the broker-dealer will attempt to sell the securities as agent but may position and resell a portion of the block as principal to facilitate the transaction;

•

purchases by a broker-dealer as principal and resale by the broker-dealer for its account;

•

an exchange distribution in accordance with the rules of the applicable exchange;

•

privately negotiated transactions;

•

settlement of short sales;

•

in transactions through broker-dealers that agree with the Selling Stockholders to sell a specified number of such securities at a stipulated price per security;

•

through the writing or settlement of options or other hedging transactions, whether through an options exchange or otherwise;

•

a combination of any such methods of sale; or

•

any other method permitted pursuant to applicable law

The Selling Stockholders may also sell securities under Rule 144 or any other exemption from registration under the Securities Act of 1933, as amended, if available, rather than under this prospectus.

Broker-dealers engaged by the Selling Stockholders may arrange for other brokers-dealers to participate in sales. Broker-dealers may receive commissions or discounts from the Selling Stockholders (or, if any broker-dealer acts as agent for the purchaser of securities, from the purchaser) in amounts to be negotiated, but, except as set forth in a supplement to this Prospectus, in the case of an agency transaction not in excess of a customary brokerage commission in compliance with FINRA Rule 2440; and in the case of a principal transaction a markup or markdown in compliance with FINRAIM-2440.

In connection with the sale of the securities or interests therein, the Selling Stockholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the securities in the course of hedging the positions they assume. The Selling Stockholders may also sell securities short and deliver these securities to close out their short positions, or loan or pledge the securities to broker-dealers that in turn may sell these securities. The Selling Stockholders may also enter into option or other transactions with broker-dealers or other financial institutions or create one or more derivative securities which require the delivery to such broker-dealer or other financial institution of securities offered by this prospectus, which securities such broker-dealer or other financial institution may resell pursuant to this prospectus (as supplemented or amended to reflect such transaction).

The Selling Stockholders and any broker-dealers or agents that are involved in selling the securities may be deemed to be “underwriters” within the meaning of the Securities Act in connection with such sales. In such event, any commissions received by such broker-dealers or agents and any profit on the resale of the securities

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of the financial condition and results of operations of Delcath Systems, Inc. (“Delcath” or the “Company”) should be read in conjunction with the consolidated financial statements and notes thereto contained in this prospectus.

Overview

Delcath Systems, Inc. is an interventional oncology company focused on the treatment of primary and metastatic liver cancers. Our investigational product—Melphalan Hydrochloride for Injection for use with the Delcath Hepatic Delivery System (“Melphalan/HDS”) —is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated side effects. In Europe, our system is commercially available under the trade name Delcath Hepatic CHEMOSAT^® Delivery System for Melphalan (“CHEMOSAT”), where it has been used at major medical centers to treat a wide range of cancers of the liver.

Our Ability to Continue as a Going Concern

The notes to our financial statements include a disclosure describing the existence of conditions that raise substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern is

dependent upon our ability to obtain substantial additional funding in connection with our continuing operations. Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to raise additional capital and/or enter into strategic alliances when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or any commercialization efforts. Our consolidated financial statements have been prepared under the assumption that we will continue as a going concern. If we are not able to continue as a going concern, it is likely that holders of our Common Stock will lose all of their investment. Our consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Our independent registered public accounting firm has issued its report dated June 14, 2019 in connection with the audit of our consolidated financial statements as of December 31, 2018 that included an explanatory paragraph describing the existence of conditions that raise substantial doubt about our ability to continue as a going concern.

Liquidity and Capital Resources (for the year ended December 31, 2018)

The Company’s future results are subject to substantial risks and uncertainties. As noted above, Delcath has operated at a loss for its entire history and anticipates that losses will continue over the coming year. There can be no assurance that Delcath will ever generate significant revenues or achieve profitability. The Company expects to use cash, cash equivalents and investment proceeds to fund its operating activities. Delcath’s future liquidity and capital requirements will depend on numerous factors, including the progress of clinical trials and research and product development programs, obtaining approvals and complying with regulations; the timing and effectiveness of product commercialization activities, including marketing arrangements; the timing and costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights; and the effect of competing technological and market developments.

At December 31, 2018, the Company had cash and cash equivalents totaling $2.5 million, as compared to cash and cash equivalents totaling $4.0 million at December 31, 2017. During the year ended December 31, 2018, the Company used $14.7 million of cash for its operating activities, which compares to $15.4 million used for operating activities during the year ended December 31, 2017. The increase of $0.7 million was primarily driven by an increase in operating expenses primarily related to the Company’s clinical trial effort discussed in the Overview section above. In light of recent financing activities described below, the Company believes it has sufficient capital to fund its operating activities through June 2019.

Our consolidated financial statements as of December 31, 2018 have been prepared under the assumption that we will continue as a going concern for the next twelve months. We expect to incur significant expenses and operating losses for the foreseeable future. These factors raise substantial doubt about our ability to continue as a going concern. Because Delcath’s business does not generate positive cash flow from operating activities, the Company will need to obtain substantial additional capital in order to fund clinical trial research and support our development efforts and to fully commercialize our product. The Company believes it will be able to raise additional capital in the event it is in its best interest to do so. The Company anticipates raising such additional capital by either selling shares of Delcath’s capital stock, borrowing money or entering into strategic alliances with appropriate partners. To the extent additional capital is not available when needed or on acceptable terms, the Company may be forced to abandon some or all of its development and commercialization efforts, which would have a material adverse effect on the prospects of its business. Further, the Company’s assumptions relating to its cash requirements may differ materially from its actual requirements because of a number of factors, including significant unforeseen delays in the regulatory approval process, changes in the timing, scope, focus and direction of clinical trials and costs related to commercializing the product.

The Company has funded its operations through a combination of private placements and public offerings of securities in 2000, 2003, 2009, 2010, 2011, 2012, 2013, 2015, 2016 and 2018, including registered direct offerings in 2007, 2009 and 2013, “at the market” equity offering programs in 2012 and 2013, a rights offering in

2018 and by the private placement of convertible notes in 2016 and 2018. For a detailed discussion of the Company’s various sales of debt and equity securities see Notes 10 and 11 to the Company’s audited consolidated financial statements contained in our Annual Report on Form10-K.

In October 2018, the Company filed a registration statement on FormS-3 with the SEC, which was declared effective on December 21, 2018 and allowed the Company to offer and sell, from time to time in one or more offerings, up to $100.0 million of Common Stock, preferred stock, warrants, debt securities and stock purchase contracts as it deems prudent or necessary to raise capital at a later date. The Company has lost its FormS-3 eligibility due to the late filing of our Annual Report on Form10-K for the fiscal year ended December 31, 2018 and our Quarterly Report on Form10-Q for the fiscal quarter ended March 31, 2019.

Since the close of our most recent fiscal year, we have borrowed an aggregate of $3.3 million from institutional investors. See Note 15 to the Company’s audited consolidated financial statements contained in our Annual Report on Form10-K for a discussion of these subsequent events.

Future Capital Needs; Additional Future Funding

The Company’s future results are subject to substantial risks and uncertainties. The Company has operated at a loss for its entire history and there can be no assurance that it will ever achieve consistent profitability. Based upon recent financing activities described above, the Company believes that it has adequate resources to fund operations through June 2019. Additional working capital will be required to continue operations. There can be no assurance that such working capital will be available on acceptable terms, if at all.

Results of Operations for the three and nine months ended September 30, 2019; Comparisons of Results of Operations for three and nine months ended September 30, 2018

Three months ended September 30, 2019 and September 30, 2018

Revenue

The Company recorded approximately $0.2 million in revenue related to product sales for the three months ended September 30, 2019 and $0.8 million in revenue related to product sales for the three months ended September 30, 2018. The decrease was slightly offset by $0.2 million in other revenue. Other revenue and the decrease in product revenue are both related to the Company entering into a licensing agreement with medac as discussed further in the Market Access and Commercial Clinical Adoption section above.

Cost of Goods Sold

For the three months ended September 30, 2019, the Company recorded cost of goods sold of approximately $0.2 million compared to $0.2 million for the three months ended September 30, 2018. The decrease of approximately $60,000 is related to an adjustment in the allocation of expenses into COGS during 2019.

Selling, General and Administrative Expenses

For the three months ended September 30, 2019 and 2018, selling, general and administrative expenses were $4.0 million and $2.3 million, respectively. The increase for the three months ended September 30, 2019 is primarily related to $0.9 million in settlement expenses, which was anon-cash expense discussed further in Note 9 and $0.6 million in expenses related to litigation that was settled in July and August 2019.

Research and Development Expenses

For the three months ended September 30, 2019 and 2018, research and development expenses decreased to $1.8 million from $4.1 million. The decrease was primarily due a reduced rate of enrollment and related professional services related to the ongoing accrual of the Company’s FOCUS trial which is discussed in further detail in the Active Clinical Development Program section above. The reduction is related to the cash constraints the Company experienced during the first half of 2019.

Change in the fair value of the warrant liability

For the three months ended September 30, 2019 the change in the fair value of the warrant liability was approximately $0.4 million as compared to $1.2 million for the three months ended September 30, 2018. The decrease of $0.8 million is due to the reclassification of certain warrants from liability to equity in 2018 and themark-to-market adjustments to the Warrant liability as discussed in more detail in Note 10 to the Company’s interim condensed consolidated financial statements contained in this Quarterly Report on Form10-Q.

Other Income/Expense

Other expense and interest expense are primarily related to the amortization of debt discounts discussed in Note 8 of the Company’s condensed consolidated financial statements contained in this Quarterly Report on Form10-Q, as well as foreign currency exchange gains and losses.

Interest income is from a money market account and interest earned on operating accounts.

Net Loss

The Company recorded a net loss for the three months ended September 30, 2019 of $7.5 million, a decrease of $1.4 million, or 15.3%, compared to net loss of $8.9 million for the same period in 2018. This increase in net loss is primarily due to a $0.6 million decrease in operating expenses, a $0.4 million decrease in gross profit, and a $1.2 million change innon-cash expense items including the fair value of the warrant liability, loss on the issuance of financial instruments and interest expense.

Nine months ended September 30, 2019 and September 30, 2018

Revenue

The Company recorded approximately $0.5 million in revenue related to product sales for the nine months ended September 30, 2019 and $2.4 million in revenue related to product sales for the nine months ended September 30, 2018. The decrease was slightly offset by $0.5 million in other revenue. Other revenue and the decrease in product revenue are both related to the Company entering into a licensing agreement with medac as discussed further in the Market Access and Commercial Clinical Adoption section above.

Cost of Goods Sold

For the nine months ended September 30, 2019, the Company recorded cost of goods sold of approximately $0.4 million compared to $0.6 million for the nine months ended September 30, 2018. The decrease is related to an adjustment in the allocation of expenses into COGS during 2019.

Selling, General and Administrative Expenses

For the nine months ended September 30, 2019 and 2018, selling, general and administrative expenses were $9.2 million and $7.3 million, respectively. The increase for the nine months ended September 30, 2019 is primarily related to $0.9 million in settlement expenses, which was anon-cash expense discussed further in Note 9 and $0.8 million in expenses related to litigation that was settled in July and August 2019.

Research and Development Expenses

For the nine months ended September 30, 2019 and 2018, research and development expenses decreased to $6.8 million from $13.9 million. The decrease was primarily due a reduced rate of enrollment and related professional services related to the ongoing accrual of the Company’s FOCUS trial which is discussed in further detail in the Active Clinical Development Program section above. The reduction is related to the cash constraints the Company experienced during the first half of 2019.

Change in the fair value of the warrant liability

For the nine months ended September 30, 2019 the change in the fair value of the warrant liability was approximately $10,000 as compared to $18.4 million for the nine months ended September 30, 2018. The decrease of $18.0 million is due to the reclassification of certain warrants from liability to equity in 2018 and the continuedmark-to-market adjustments to the remaining Warrant liability as discussed in more detail in Note 10 to the Company’s interim condensed consolidated financial statements contained in this Quarterly Report on Form10-Q.

Other Income/Expense

Interest income is from a money market account and interest earned on operating accounts.

Net Loss

The Company recorded a net loss for the nine months ended September 30, 2019 of $21.4 million, a decrease of $13.0 million compared to net loss of $8.4 million for the same period in 2018. This increase in net loss is primarily due to a $18.0 million change in the fair value of the warrant liability, anon-cash item, a $5.2 million decrease in operating expenses and a $1.2 decrease in gross profits.

Liquidity and Capital Resources

The Company received gross proceeds of $29.5 million through two private placements in July and August 2019, providing funding through the second quarter of 2020. The Company will need to raise additional capital under structures available to it including debt and/or equity offerings. If these sources do not provide the capital necessary to fund the Company’s operations, the Company will need to curtail certain aspects of its operations or consider other means of obtaining additional financing, although there is no guarantee that the Company could obtain the financing necessary to continue its operations.

The Company’s future results are subject to substantial risks and uncertainties. Delcath has operated at a loss for its entire history and anticipates that losses will continue over the coming years. There can be no assurance that Delcath will ever generate significant revenues or achieve profitability. The Company expects to use cash, cash equivalents and investment proceeds to fund its clinical and operating activities. Delcath’s future liquidity and capital requirements will depend on numerous factors, including the initiation and progress of clinical trials and research and product development programs; obtaining approvals and complying with regulations; the timing and effectiveness of product commercialization activities, including marketing arrangements; the timing and costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights; and the effect of competing technological and market developments.

At September 30, 2019, the Company had cash, cash equivalents and restricted cash totaling $15.5 million, as compared to cash, cash equivalents and restricted cash totaling $3.6 million at December 31, 2018 and $10.0 million at September 30, 2018. During the three and nine months ended September 30, 2019 and 2018, the Company used $18.3 million and $12.9 million respectively, of cash in its operating activities.

Our condensed consolidated financial statements as of September 30, 2019 have been prepared under the assumption that we will continue as a going concern for the next twelve months. We expect to incur significant expenses and operating losses for the foreseeable future. These factors raise substantial doubt about our ability to continue as a going concern. Because Delcath’s business does not generate positive cash flow from operating activities, the Company will need to obtain substantial additional capital in order to fund clinical trial research and support development efforts relating to ocular melanoma liver metastases, ICC, HCC or other indications, and to fully commercialize the product. The Company believes it will be able to raise additional capital in the event it is in its best interest to do so. The Company anticipates raising such additional capital by either borrowing money, selling shares of Delcath’s capital stock, or entering into strategic alliances with appropriate partners. To the extent additional capital is not available when needed or on acceptable terms, the Company may be forced to abandon some or all of its development and commercialization efforts, which would have a material adverse effect on the prospects of its business. Further, the Company’s assumptions relating to its cash requirements may differ materially from its actual requirements because of a number of factors, including significant unforeseen delays in the regulatory approval process, changes in the timing, scope, focus and direction of clinical trials and costs related to commercializing the product.

The Company has funded its operations through a combination of private placements and public offerings of its securities in each of 2000, 2003, 2009, 2010, 2011, 2012, 2013, 2015, 2016, 2018 and 2019, including registered direct offerings in 2007, 2009 and 2013, “at the market” equity offering programs in 2012 and 2013, and by the private placement of convertible notes in 2016 and 2018, and, most recently, in July and August 2019, the Company raised $29.5 million in the closing of two private placements of convertible preferred stock and warrants to purchase Common Stock. For a detailed discussion of the Company’s various sales of debt and equity securities see Notes 8, 9, and 14 to the Company’s condensed consolidated financial statements contained in this Quarterly Report on Form10-Q as well as Notes 10 and 11 to the Company’s audited consolidated financial statements contained in its Annual Report for the fiscal year ended December 31, 2018.

purchase contracts as it deems prudent or necessary to raise capital at a later date. The Company has lost its FormS-3 eligibility due to the late filing of its Annual Report for the year ended December 31, 2018.

The Company intends to use the net proceeds from any future offerings for general corporate purposes, including, but not limited to, funding of clinical trials, obtaining regulatory approvals, commercialization of its products, capital expenditures and working capital.

Results of Operations for the Year Ended December 31, 2018; Comparisons of Results of the Years Ended December 31, 2018 and 2017

Revenue

The Company recorded approximately $3.4 million in product revenue during the year ended December 31, 2018. During the same period in 2017, Delcath recorded $2.7 million in total revenue related to product sales. The year over year increase is a result of greater product sales in 2018 as Delcath continues to see increased market acceptance of its product in the EU, particularly in Germany where the establishment of the ZE code has contributed to increased treatments.

Additionally, the Company recorded approximately $29,000 in other revenue which is related to the amortization of certain payments pursuant to a definitive licensing agreement for CHEMOSAT commercialization in Europe between the Company and medac Gesellschaft für klinische Spezialpräparate mbH (“Medac”) signed on December 17, 2018 and discussed further in Part I, Item 1 under the section captioned “Market Access and Commercial Clinical Adoption” above.

The adoption of ASC 606 on January 1, 2018 had no impact on the amount and timing of revenue recognition related to product sales.

Cost of Goods Sold

During the year ended December 31, 2018, the Company recognized cost of goods sold of approximately $1.0 million related to product revenue of $3.4 million as compared to cost of goods sold of approximately $0.7 million related to product revenue of $2.7 million in the comparable prior period.

The increase in cost of goods sold is commensurate with the increase in revenue.

Selling, General and Administrative Expenses

For the year ended December 31, 2018, selling, general and administrative expenses increased to $9.8 million from $9.7 million for the year ended December 31, 2017. The slight increase reflects the Company’s efforts to focus its resources on its clinical development program.

Research and Development Expenses

For the year ended December 31, 2018, research and development expenses increased to $19.7 million from $10.5 million for the year ended December 31, 2017. The increase of $9.2 million is primarily due to the ongoing efforts of the FOCUS Trial which is discussed in further detail in Part 1, Item 1 in the section captioned “Current Clinical Development Program” above.

Other Income/Expense and Interest Expense

Other expense is primarily related to foreign currency exchange gains and losses.

Interest expense is related to the restructuring lease liability discussed in Note 9 of the Company’s audited consolidated financial statements contained in our Annual Report on Form10-K and the amortization of debt discounts discussed in Note 10 of the Company’s audited consolidated financial statements contained in our Annual Report on Form10-K.

Interest income is from a money market account and interest earned on operating accounts.

Change in Fair Value of Derivative Liability

For the year ended December 31, 2018, derivative instrument income increased to $19.7 million from $15.1 million for the year ended December 31, 2017. The increase of $4.6 million is primarily related to themark-to-market adjustments to the warrant liability discussed in more detail in Note 12 to the Company’s audited consolidated financial statements contained in our Annual Report on Form10-K.

Net Loss

The Company had a net loss for the year ended December 31, 2018 of $19.2 million, a decrease of $25.9 million, or 57.4%, compared to the net loss for the same period in 2017. This decrease is due in significant part to a $34.7 million decrease in variousnon-cash items primarily related to the amortization of debt discounts and other transaction costs related to convertible notes issued in 2016 and 2018, and discussed in greater detail in Note 10 of the Company’s consolidated financial statements contained in our Annual Report on Form10-K, offset by a $9.3 million increase in operating expenses primarily related to increased investment in clinical trial initiatives.

Income Taxes

The Company has not recorded a provision for income taxes for the years ending December 31, 2018 and 2017, respectively, due to being in a net tax operating loss position for each of those years.

On December 22, 2017, the 2017 Tax Cuts and Jobs Act (the “Tax Act”) was enacted into law and the new legislation contains several key tax provisions that affected the Company, including aone-time mandatory transition tax on accumulated foreign earnings and a reduction of the corporate income tax rate to 21% effective January 1, 2018, among others. The Company was required to recognize the effect of the tax law changes in the period of enactment, such as determining the transition tax, remeasuring our U.S. deferred tax assets and liabilities as well as reassessing the net realizability of our deferred tax assets and liabilities. In December 2017, the Securities and Exchange Commission issued Staff Accounting Bulletin No. 118, Income Tax Accounting Implications of the Tax Cuts and Jobs Act (“SAB 118”), which allowed the Company to record provisional amounts during a measurement period not to extend beyond one year of the enactment date. Since the Tax Act was passed late in the fourth quarter of 2017, and ongoing guidance and accounting interpretation were expected in 2018, the Company considered the accounting of deferred taxre-measurements and the transition tax to be incomplete due to the forthcoming guidance and our ongoing analysis of finalyear-end data and tax positions. However, during the year ended December 31, 2017 the Company was able to determine a provisional amount of $143,500 (offset by valuation allowance) and $0, respectively, related to the deferred taxre-measurement andone-time transition tax. See Note 14 to the Company’s audited consolidated financial statements contained in our Annual Report on Form10-K. The Company finalized its accounting of the effects of tax reform in 2018, which resulted in insignificant adjustments.

Application of Critical Accounting Policies

The Company’s consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”). Certain accounting policies have a significant impact on amounts reported in the consolidated financial statements. A summary of those significant accounting policies can be found in Note 3 to the Company’s audited consolidated financial statements contained in our Annual Report on Form10-K.

The Company considers the valuation allowance for the deferred tax assets to be a significant accounting estimate. A valuation allowance has been recorded against the Company’s deferred tax assets as

management believes it is more likely than not that the deferred tax assets will not be realized. In assessing whether it is more likely than not that the Company will realize the benefits of its deferred tax assets, management considers all forms of available evidence, including the Company’s history of cumulative losses, estimates of future taxable income and losses (including reversals of deferred tax liabilities), and available tax planning strategies. Since the Company is in a cumulative loss position, it cannot rely on future taxable income as a source of taxable income because the Company views a cumulative loss position as significant objective negative evidence that would be difficult to overcome with the other subjective tests discussed. The Company does not have taxable income in prior years to absorb the carryback of net operating losses, nor has it implementedtax-planning strategies that would, if necessary, be implemented to allow for the usage of net operating losses.

Prior to ASU2016-16, GAAP prohibited the recognition of current and deferred income taxes for intra-entity asset transfers until the asset has been sold to an outside party. ASU2016-16 eliminates this prohibition for intra-entity transfers of assets other than inventory but retain the prohibition for intra-entity transfers of inventory. This standard is effective for public entities for fiscal years beginning after December 15, 2017. On January 1, 2012, Delcath Systems, Inc. sold a portion of its intellectual property to affiliate, Delcath Holdings Limited, resulting in a taxable gain of $15.8 million in the U.S. based on the fair market value of the intangible that was transferred. The arms-length price, which was determined in accordance with Section 482 of the Internal Revenue Code, is a significant accounting estimate. Prior to ASU 2016-2016, the gain was deferred under GAAP principles until the asset is sold outside of the consolidated financial statements. The remaining deferred gain on the intercompany sale of intangible assets is $2.0 million as of December 31, 2017. The Company adopted ASU2016-16, effective on January 1, 2018. As a result of adoption, the Company immediately recognized the $2.0 million deferred gain and none remains as of December 31, 2018.

The Company has adopted the provisions of Accounting Standard Codification (“ASC”) 718, Stock-Based Compensation, which establishes accounting for equity instruments exchanged for employee services. Under the provisions of ASC 718, share-based compensation is measured at the grant date, based upon the fair value of the award, and is recognized as an expense over the option holders’ requisite service period (generally the vesting period of the equity grant). The Company expenses its share-based compensation under the accelerated method, which treats each vesting tranche as if it were an individual grant.

The Company has adopted the provisions of ASC505-50, Equity-Based Payments toNon-Employees, which establishes accounting for equity-based payments tonon-employees. Measurement of compensation cost related to common shares issued tonon-employees for services is based on the value of the services provided or the fair value of the shares issued. Each transaction is reviewed to determine the more reliably measurable basis for the valuation. The measurement ofnon-employee stock-based compensation is subject to periodic adjustment as the underlying equity instrument vests.Non-employee stock-based compensation charges are amortized over the vesting period or period of performance of the services.

The Company has adopted the provisions of ASC 820, Fair Value Measurement, which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements.

ASC 820 emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Therefore, a fair value measurement should be determined based on the assumptions that market participants would use in pricing the asset or liability. As a basis for considering market participant assumptions in fair value measurements, ASC 820 establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy).

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access. Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted

prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability. See Note 12 to the Company’s audited consolidated financial statements contained in our Annual Report on Form10-K for assets and liabilities the Company has evaluated under ASC 820.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Stockholders and Board of Directors of

Delcath Systems, Inc. and Subsidiaries

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheet of Delcath Systems, Inc. and Subsidiaries (the “Company”) as of December 31, 2018, the related consolidated statements of operations and comprehensive loss, stockholders’ equity and cash flows for the year ended December 31, 2018, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2018, and the results of its operations and its cash flows for the year ended December 31, 2018, in conformity with accounting principles generally accepted in the United States of America.

Explanatory Paragraph—Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As more fully described in Note 1, the Company has a working capital deficiency, has incurred losses and needs to raise additional funds to meet its obligations and sustain its operations. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 1. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB.Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audit provides a reasonable basis for our opinion.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Board of Directors and Stockholders Delcath Systems, Inc.

Opinion on the financial statements

We have audited the accompanying consolidated balance sheet of Delcath Systems, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2017, the related consolidated statement of operations, changes in stockholders’ equity, and cash flow for the year ended December 31, 2017, and the related notes (collectively referred to as the “financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2017, and the results of its operations and its cash flow for the year ended December 31, 2017, in conformity with accounting principles generally accepted in the United States of America.

Going concern

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the 2017 consolidated financial statements, the Company has incurred recurring losses from operations and as of December 31, 2017 has an accumulated deficit of $324.8 million. These conditions, along with other matters as set forth in Note 1 to the 2017 consolidated financial statements, raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also discussed in Note 1 to the 2017 consolidated financial statements. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

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

Our audit included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements.

Notes to Consolidated Financial Statements

for the Years Ended December 31, 2018 and 2017

(1)

DESCRIPTION OF BUSINESS

Our primary research focus is on ocular melanoma liver metastases (“mOM”) and intrahepatic cholangiocarcinoma (“ICC”) and certain other cancers that are metastatic to the liver. Currently there are few effective treatment options for certain cancers in the liver. Traditional treatment options include surgery, systemic chemotherapy, liver transplant, radiation therapy, interventional radiology techniques, and isolated hepatic perfusion. We believe that Melphalan/HDS and CHEMOSAT represent a potentially important advancement in regional therapy for primary liver cancer and certain other cancers metastatic to the liver and are uniquely positioned to treat the entire liver either as a standalone therapy or as a complement to other therapies.

While we currently utilize third parties to manufacture some components of our product, we also have our own manufacturing operations for certain components of our product and assemble and package our products in Queensbury, New York. See the discussion in Part 1, Item 1 under the caption “Manufacturing and Quality Assurance” above.

We commercialize our product in Europe through alliances with third parties.

Liquidity

The accompanying financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. As shown in the accompanying financial statements during the year ended December 31, 2018, the Company incurred net losses of $19.2 million and used $14.7 million of cash for its operating activities. These factors among others raise substantial doubt about the Company’s ability to continue as a going concern for a reasonable period of time.

The Company’s existence is dependent upon management’s ability to obtain additional funding sources or to enter into strategic alliances. Adequate additional financing may not be available to us on acceptable terms, or at all. If the Company is unable to raise additional capital and/or enter into strategic alliances when needed or on attractive terms, it would be forced to delay, reduce or eliminate our research and development programs or any commercialization efforts. There can be no assurance that the Company’s efforts will result in the resolution of the Company’s liquidity needs. If Delcath is not able to continue as a going concern, it is likely that holders of its Common Stock will lose all of their investment. The accompanying consolidated financial statements do not include any adjustments that might result should the Company be unable to continue as a going concern.

The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales. At December 31, 2018, management believed that its capital resources were adequate to fund operations through March 2019. Additional working capital will be required to continue operations.

F-8

Operations of the Company are subject to certain risks and uncertainties, including, among others, uncertainty of product development and clinical trial results; uncertainty regarding regulatory approval; technological uncertainty; uncertainty regarding patents and proprietary rights; comprehensive government regulations; limited commercial manufacturing, marketing or sales experience; and dependence on key personnel. See Note 15 of these notes to the Company’s audited consolidated financial statements relating to subsequent events.

(2)

BASIS OF CONSOLIDATED FINANCIAL STATEMENT PRESENTATION

The accounting and financial reporting policies of the Company conform to generally accepted accounting principles in the United States of America (“GAAP”). The preparation of consolidated financial statements in conformity with GAAP requires management to make assumptions and estimates that impact the amounts reported in the Company’s consolidated financial statements. The consolidated financial statements include the accounts of all entities controlled by Delcath. All significant inter-company accounts and transactions are eliminated.

Reverse Stock Splits

All share numbers presented in this footnote reflect aone-for-three hundred and fifty (1:350) reverse stock split effected on November 6, 2017, aone-for-five hundred (1:500) reverse stock split effected on May 2, 2018, and aone-for-seven hundred (1:700) reverse stock split effected on December 24, 2019.

(3)

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The Company bases its estimates and judgments on historical experience and on various other assumptions that it believes are reasonable under the circumstances. The amounts of assets and liabilities reported in the Company’s consolidated balance sheets and the amount of revenues and expenses reported for each of the periods presented are affected by estimates and assumptions, which are used for, but not limited to, the accounting for derivative instrument liabilities, stock-based compensation, valuation of inventory, impairment of long-lived assets, income taxes and operating expense accruals. Such assumptions and estimates are subject to change in the future as additional information becomes available or as circumstances are modified. Actual results could differ from these estimates.

Cash Equivalents and Concentrations of Credit Risk

The Company considers investments with original maturities of three months or less at date of acquisition to be cash equivalents. The Company has deposits that exceed amounts insured by the Federal Deposit Insurance Corporation (“FDIC”), however, the Company does not consider this a significant concentration of credit risk based on the strength of the financial institution.

Restricted Cash

Cash and cash equivalents that are restricted as to withdrawal or use under the terms of certain contractual agreements are recorded as restricted cash on the accompanying consolidated balance sheets.

Accounts Receivable

Accounts receivable, principally trade, are generally due within 30 days and are stated at amounts due from customers. Collections and payments from customers are monitored and a provision for estimated credit losses may be created based upon historical experience and specific customer collection issues that may be identified.

F-9

Inventories

Inventories are valued at the lower of cost or market value using thefirst-in,first-out method. The reported net value of inventory includes finished saleable products,work-in-process, and raw materials that will be sold or used in future periods. The Company reserves for expired, obsolete, and slow-moving inventory.

Property, Plant and Equipment

Property, plant and equipment are recorded at cost, less accumulated depreciation. The Company provides for depreciation on a straight line basis over the estimated useful lives of the assets which range from three to seven years. Leasehold improvements will be amortized over the shorter of the lease term or the estimated useful life of the related assets when they are placed into service. The Company evaluates property, plant and equipment for impairment periodically to determine if changes in circumstances or the occurrence of events suggest the carrying value of the asset or asset group may not be recoverable. Maintenance and repairs are charged to operations as incurred. Expenditures which substantially increase the useful lives of the related assets are capitalized.

Derivative Instrument Liability

The Company accounts for derivative instruments in accordance with Accounting Standards Codification (“ASC”) 815, Derivatives and Hedging, which establishes accounting and reporting standards for derivative instruments and hedging activities, including certain derivative instruments embedded in other financial instruments or contracts and requires recognition of all derivatives on the balance sheet at fair value, regardless of the hedging relationship designation. Accounting for changes in the fair value of the derivative instruments depends on whether the derivatives qualify as hedge relationships and the types of relationships designated are based on the exposures hedged. At December 31, 2018 and 2017, the Company did not have any derivative instruments that were designated as hedges.

Fair Value Measurements

The Company adheres to ASC 820, Fair Value Measurement, which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. ASC 820 applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements; accordingly, the standard does not require any new fair value measurements of reported balances.

•

Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access.

•

Level 2 inputs are inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs may include quoted prices for similar assets and liabilities in active markets, as well as inputs that are observable for the asset or liability (other than quoted prices), such as interest rates, foreign exchange rates, and yield curves that are observable at commonly quoted intervals.

F-10

•

Level 3 inputs are unobservable inputs for the asset or liability, which is typically based on an entity’s own assumptions, as there is little, if any, related market activity.

In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset or liability.

Revenue Recognition

Revenue is generated from proprietary and partnered product sales and license and royalty arrangements. Revenue is recognized when or as we transfer control of the promised goods or services to our customers in an amount that reflects the consideration to which we expect to be entitled to in exchange for those goods or services. When obligations or contingencies remain after the products are shipped, such as training and certifying the treatment centers, revenue is deferred until the obligations or contingencies are satisfied.

We may enter into contracts with partners that contain multiple elements such as licensing, development, manufacturing and commercialization components. These arrangements are often complex and we may receive various types of consideration over the life of the arrangement, including:up-front fees, reimbursements for research and development services, milestone payments, payments on product shipments, margin sharing arrangements, license fees and royalties.

Our results of operations for reporting periods beginning on or after January 1, 2018 are presented under ASC 606, Revenue from Contracts with Customers, while prior period amounts, as reported, are not adjusted. The effects of the adoption of the new standard in 2018 were not material to our consolidated financial statements. In assessing our revenue arrangements in accordance with ASC 606, Revenue from Contracts with Customers, we must identify the contract, determine the transaction price including an estimation of any variable consideration we expect to receive in connection with the contract, identify the promises of goods or services to the customer and each distinct performance obligation, allocate the transaction price to each of the performance obligations, and recognize revenue when or as the performance obligations are satisfied. Each of these steps in the revenue recognition process requires management to make judgements and/or estimates. The most significant judgements and estimates involve the determination of variable consideration to be included in the transaction price. Variable consideration is recognized at an amount we believe is not subject to significant reversal and is adjusted at each reporting period if the most likely amount of expected consideration changes or becomes fixed. We believe this provides a reasonable basis for recognizing revenue, however, actual results could differ from estimates and significant changes in estimates could impact our results of operations in future periods.

Deferred Revenue

License fees and milestones received in exchange for the grant of a license for the commercialization of CHEMOSAT are generally recognized over the development period, as the license is considered distinct from the delivery of product. Milestone payments that are contingent upon the occurrence of future events, are evaluated and recorded at the most likely amount, and to the extent that it is probable that a significant reversal will not occur when the associated uncertainty is resolved.

Selling, General and Administrative

Selling, general and administrative costs include personnel costs and related expenses for the Company’s sales, marketing, general management and administrative staff, recruitment, costs related to the Company’s commercialization efforts in Europe, professional service fees, professional license fees, business development and certain general legal activities. All such costs are charged to expense when incurred.

F-11

Research and Development

Research and development costs include the costs of materials used for clinical trials and R&D, personnel costs associated with device and pharmaceutical R&D, clinical affairs, medical affairs, medical science liaisons, and regulatory affairs, costs of outside services and applicable indirect costs incurred in the development of the Company’s proprietary drug delivery system. All such costs are charged to expense when incurred.

Stock Based Compensation

The Company accounts for its share-based compensation in accordance with the provisions of ASC 718, Stock-Based Compensation, which establishes accounting for equity instruments exchanged for employee services and ASC505-50, Equity-Based Payments toNon-Employees, which establishes accounting for equity-based payments tonon-employees. Under the provisions of ASC 718, share-based compensation is measured at the grant date, based upon the fair value of the award, and is recognized as an expense over the option holders’ requisite service period (generally the vesting period of the equity grant). The Company is required to record compensation cost for all share-based payments granted to employees based upon the grant date fair value, estimated in accordance with the provisions of ASC 718. Under the provisions of ASC505-50, measurement of compensation cost related to common shares issued tonon-employees for services is based on the value of the services provided or the fair value of the shares issued. The measurement ofnon-employee stock-based compensation is subject to periodic adjustment as the underlying equity instrument vests. The Company expenses its share-based compensation for share-based payments granted under the accelerated method, which treats each vesting tranche as if it were an individual grant.

The Company periodically grants stock options for a fixed number of shares of Common Stock to its employees, directors andnon-employee contractors, with an exercise price greater than or equal to the fair market value of Delcath’s Common Stock at the date of the grant. The Company estimates the fair value of stock options using an option pricing model. Key inputs used to estimate the fair value of stock options include the exercise price of the award, the expected post-vesting option life, the expected volatility of Delcath’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and Delcath’s expected annual dividend yield. Estimates of fair value are not intended to predict actual future events or the value ultimately realized by persons who receive equity awards.

Income Taxes

The Company accounts for income taxes following the asset and liability method in accordance with the ASC 740, Income Taxes. Under such method, deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the consolidated financial statement carrying amounts of existing assets and liabilities and their respective tax bases. The Company applies the accounting guidance issued to address the accounting for uncertain tax positions. This guidance clarifies the accounting for income taxes, by prescribing a minimum recognition threshold a tax position is required to meet before being recognized in the financial statements as well as provides guidance on derecognition, measurement, classification, interest and penalties, accounting in interim periods, disclosure and transition. The Company classifies interest and penalty expense related to uncertain tax positions as a component of income tax expense. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years that the asset is expected to be recovered or the liability settled. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income and tax planning strategies in its assessment of a valuation allowance. See Note 14 for additional information.

Net Loss per Common Share

Basic net loss per share is determined by dividing net loss by the weighted average shares of Common Stock outstanding during the period. Diluted net loss per share is determined by dividing net loss by diluted weighted average shares outstanding. Diluted weighted average shares reflects the dilutive effect, if any, of potentially dilutive common shares, such as stock options and warrants calculated using the treasury stock method. In periods with reported net operating losses, all stock options, unvested restricted stock and warrants are deemed anti-dilutive such that basic net loss per share and diluted net loss per share are equal.

The calculation of net loss and the number of shares used to compute basic and diluted earnings per share for the years ended December 31, 2018 and 2017:


	December 31,
(in thousands, except share data)	2018			2017
Net loss—basic	$	(19,222	)	$	(45,117	)

In the third quarter of 2017, the Company issued Series B Preferred Shares. A portion of the redemption price of the Series B Preferred Shares was accounted for as a deemed dividend.

At December 31, 2018, the Company has 0.1 millionpre-funded warrants outstanding. The following table provides a reconciliation of the weighted average shares outstanding calculation at December 31, 2018:


	December 31, 2018
Weighted average shares issued		3,913
Weighted averagepre-funded warrants		34,238

Weighted average shares outstanding		38,151

For the years ended December 31, 2018 and 2017 the following potentially dilutive securities were excluded from the computation of diluted earnings per share because their effects would be antidilutive.

Shares excluded from the computation of diluted earnings per share:

Foreign Currency and Currency Translation

Transactions that are denominated in a foreign currency are remeasured into the functional currency at the current exchange rate on the date of the transaction. Any foreign currency-denominated monetary assets and liabilities are subsequently remeasured at current exchange rates, with gains or losses recognized as foreign exchange (losses)/gains in the statements of operations.

The assets and liabilities of the Company’s international subsidiaries are translated from their functional currencies into United States dollars at exchange rates prevailing at the balance sheet date. The majority of the foreign subsidiaries revenues and operating expenses are denominated in Euros. The reporting currency for the Company is the United States Dollar (“USD”). Average rates of exchange during the period are used to translate the statement of operations, while historical rates of exchange are used to translate any equity transactions.

Translation adjustments arising on consolidation due to differences between average rates and balance sheet rates, as well as unrealized foreign exchange gains or losses arising from translation of intercompany loans that are of a long-term-investment nature, are recorded in other comprehensive income.

Recently Adopted Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”)2014-09, Revenue from Contracts with Customers, that updates the principles for recognizing revenue. The core principle of the guidance is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASU2014-09 also amends the required disclosures of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. ASU2014-09 is effective for the Company beginning in its fiscal year 2018, and may be applied retrospectively to all prior periods presented or through a cumulative adjustment to the opening retained earnings balance in the year of adoption. The Company has adopted this guidance.

In June 2016, the FASB issued ASU2016-15, Statement of Cash Flows (Topic 230), which is intended to reduce diversity in practice in how certain transactions are classified in the statement of cash flows. The ASU is effective for public companies for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption was permitted, including interim periods within those fiscal years provided that those electing early adoption must adopt all of the amendments in the same period. The guidance requires application using a retrospective transition method. The Company has adopted this guidance.

In October 2016, the FASB issues ASU2016-16 which simplifies the income tax consequences of intra-entity transfers other than inventory. Prior to ASU2016-16, GAAL prohibited the recognition of current and deferred income taxes for intra-entity asset transfers until the asset has been sold to an outside party. ASU2016-16 eliminates this prohibition for intra-entity transfers of assets other than inventory but retains the prohibition for intra-entity transfers of inventory. This standard is effective go r public entities for fiscal years beginning after December 15, 2017. The Company has adopted this guidance. The adoption did not have a material impact on the Company’s consolidated financial statements.

In November 2016, the FASB issued ASU2016-18, Statement of Cash Flows (Topic 230): Restricted Cash, which requires that the statement of cash flows explain the change during the period in the total of cash, cash equivalents, and amounts generally described as restricted cash or restricted cash equivalents. Entities are also required to reconcile such total to amounts on the balance sheet and disclose the nature of the restrictions. ASU2016-18 is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years, and early adoption was permitted. The Company adopted this standard.

F-14

SEC Disclosure Update and Simplification

In August 2018, the SEC adopted the final rule under SEC ReleaseNo. 33-10532, Disclosure Update and Simplification, amending certain disclosure requirements that were redundant, duplicative, overlapping, outdated or superseded. In addition, the amendments expanded the disclosure requirements on the analysis of stockholders’ equity for interim financial statements. Under the amendments, an analysis of changes in each caption of stockholders’ equity presented in the balance sheet must be provided in a note or separate statement. The analysis should present a reconciliation of the beginning balance to the ending balance of each period for which a statement of comprehensive income is required to be filed. This final rule was effective on November 5, 2018. The adoption did not have a material impact on the Company’s consolidated financial statements.

Recent Accounting Standards to be Adopted

In February 2016, the FASB issued ASUNo. 2016-02, Leases (Topic 842), superseding ASC Topic 840, Leases. ASU2016-02 requires lessees to recognize aright-of-use asset and a lease liability on their balance sheets for all the leases with terms greater than twelve months. Based on certain criteria, leases will be classified as either financing or operating, with classification affecting the pattern of expense recognition in the income statement. For leases with a term of twelve months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. If a lessee makes this election, it should recognize lease expense for such leases generally on a straight-line basis over the lease term. ASU2016-02 is effective for fiscal years beginning after December 15, 2018, and interim periods within those years, with early adoption permitted. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. In July 2018, the FASB issued ASUNo. 2018-11, Leases (Topic 842): Targeted Improvements that allows entities to apply the provisions of the new standard at the effective date (e.g. January 1, 2019), as opposed to the earliest period presented under the modified retrospective transition approach (January 1, 2017) and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The modified retrospective approach includes a number of optional practical expedients primarily focused on leases that commenced before the effective date of Topic 842, including continuing to account for leases that commence before the effective date in accordance with previous guidance, unless the lease is modified. The Company is currently evaluating the effect the guidance will have on our audited consolidated financial statements.

In July 2017, the FASB issued ASU2017-11, Earnings Per Share (Topic 260) Distinguishing Liabilities from Equity (Topic 480) Derivatives and Hedging (Topic 815). This guidance was intended to reduce the complexity associated with the issuer’s accounting for certain financial instruments with characteristics of liabilities and equity. Specifically, the Board determined that a down round feature would no longer cause a freestanding equity-linked financial instrument (or an embedded conversion option) to be accounted for as a derivative liability at fair value with changes in fair value recognized in current earnings. In addition, the Boardre-characterized the indefinite deferral of certain provisions of Topic 480 to a scope exception. There-characterization has no accounting effect. ASU2017-11 is effective for public entities for fiscal years beginning after December 15, 2018. The Company intends to adopt this standard on January 1, 2019 and is evaluating the effects, if any, that the adoption of this guidance will have on the Company’s consolidated financial statements.

CONVERTIBLE NOTES PAYABLE (SECURED CONVERTIBLE NOTES AND RELATED COMMON STOCK PURCHASE WARRANTS)

On June 4, 2018, July 21, 2018, August 29, 2018, and September 21, 2018, the Company issued 8% senior secured convertible notes (collectively, “the Notes”) to investors with aggregate principal of $9.4 million and maturity dates between December 2018 and March 2021. The Notes are secured pursuant to a Security Agreement which creates a first priority security interest in all of the personal property (other than Excluded Collateral (as defined in the Security Agreement) of the Company of every kind and description, tangible or intangible, whether currently owned and existing or created or acquired in the future. At December 31, 2018, the Notes were convertible at $1,225 per share subject to customary terms.

In April 2019, the Company received notices of default from the investors in the Notes.

In connection with the issuance of the Notes, the Company also issued 6,005 Series D Warrants with exercise prices ranging from $1,225—$2,800 and 0.1 millionPre-Funded Series D Warrants with a purchase price of $7.00. The warrants expire 5 years from the date they could first be exercised. The provisions in the Series D Warrants andPre-Funded Series D Warrants issued in June 2018 required the Company to initially account for the warrants as derivative liabilities. The warrants were valued at $5.1 million. As a result, the Company recognized a discount to debt of $2.3 million and a loss on issuance of a financial instrument of $2.8 million.

The Company valued the June 2018 Series D Warrants using the following inputs:


	June 2018 Series D Warrant			June 2018 Pre- Funded Series D Warrants
Contractual life		5.0		5.5 - 6.5

First Amendment to June 2018 Series D Warrants

In July 2018, the Company and the investor from the June 2018 transaction amended the June 2018Pre-Funded Series D Warrants so that they are exercisable as of July 20, 2018 and the Company may redeem them at any time the Notes are no longer outstanding and the Company is not in default. The Company and the investor from the June 2018 transaction also amended the definition of a Fundamental Transaction in the June 2018 Warrants. This amendment resulted in $4.2 million related to the fair value of the June 2018 Warrants being reclassified from a liability to equity.

Amendment to June 2018 and July 2018 Notes andPre-Funded Warrants

In August 2018, the Company amended its June 2018 Notes and July 2018 Notes such that the conversion price was reduced to $1,225, interest shall accrue until maturity, and the first $2.5 million and 50% of any subsequent financings shall be used to satisfy the Company’s obligations under the Notes. Effective the

same date, the Company also amended itsPre-Funded Warrants such that the total number of June 2018Pre-Funded Warrants was increased from 18,506 to 31,724 and the total number of July 2018Pre-Funded Warrants was increased from 13,207 to 22,640. This amendment was accounted for as an extinguishment of debt as the change in cash flows exceeded 10%. The original June 2018 and July 2018 notes were written off and the amended June 2018 and July 2018 Notes were recorded at fair value as of the date of this amendment. The Company recorded $1.1 million loss on debt extinguishment related to this amendment.

STOCKHOLDERS’ EQUITY

Preferred Stock Issuances

Series D Preferred Stock

On November 5, 2018, the Company’s Board authorized the establishment of a new series of preferred stock designated as Series D Preferred Stock, $0.01 par value, the terms of which are set forth in the certificate of designations for such series of Preferred Stock which was filed with the State of Delaware on November 5, 2018.

Stock Incentive Plans

As a result of the May 2, 2018 reverse stock split, the Company’s Stock Incentive Plan has no active grants and no further shares available to be granted.

As previously reported, on February 1, 2019 the Board of Directors of the Company adopted the Company’s 2019 Equity Incentive Plan (the “2019 Plan”), pursuant to which 2,142 shares of Common Stock of the Company are available for grants through February 1, 2029 to the Company’s employees, directors and consultants. On February 1, 2019, options to purchase 1,782 shares of Common Stock, at an exercise price of $196.70 per share, were granted under the 2019 Plan to certain executive officers and employees of the Company.

Litigation

As previously reported, on March 26, 2019, the Company commenced an action (the “Action”) in the Commercial Division of the Supreme Court for the State of New York, County of New York, styled as Delcath Systems, Inc., v. Iroquois Capital Investment Group LLC, Iroquois Master Fund Ltd., L1 Capital Global Opportunities Master Fund and First Fire Global Opportunities Fund LLC (Index No. 651749/2019). The Action seeks expedited equitable relief in the form of reformation and a declaratory judgement to remedy a scrivener’s error in the Series D Warrants issued in the Company’s February 2018 public offering such that those warrants do not contain a price and quantity ratchet upon a sale of Company securities at a price lower than the offering price in the February 2018 offering. The defendant, L1 Capital Global Opportunities Master Fund, settled with the Company by exchanging its Series D Warrants for Company Common Stock on aone-for-one basis, which is the same ratio for which other investors in the February 2018 round exchanged their Series D Warrants in December 2018. The Company and the remaining defendants in the Action, Iroquois Capital Investment Group LLC, Iroquois Master Fund Ltd. and First Fire Global Opportunities Fund LLC, entered into a settlement agreement on April 18, 2019, the full text of which is annexed as Exhibit 10.42 to our Annual Report on Form10-K, pursuant to which such defendants surrendered the Series D Warrants and waived all rights granted to them by or in connection with the Series D Warrants and all rights afforded to them to participate in the Company’s future Common Stock offerings. In consideration therefor, pursuant to the settlement agreement, (i) the Company paidone-fifth of the reasonable fees and expenses of defendants’ counsel incurred in connection with the Action and negotiation of the settlement agreement, the total of which shall not exceed $50,000 (the “Settlement Fees”) and (ii) subject to the Company securing and closing certain contemplated financing, the Company agreed to pay to the defendants $400,000 and the remaining Settlement Fees.

As previously reported, on July 27, 2018, Hudson Bay Master Fund Ltd. filed a summons and complaint against the Company in the New York State Supreme Court, New York County alleging breaches by the Company of Hudson Bay’s rights of participation in future Company offerings granted in the September 2017 Securities Purchase Agreement between the Company and Hudson Bay and in the February 2018 Securities Purchase Agreement among, inter alia, the Company and Hudson Bay. In terms of relief sought, Hudson Bay claimed both monetary damages (which it claims to be in excess of $1 million) and specific performance. The Company denied any liability with respect to the claims set forth in the lawsuit. As previously reported, on January 4, 2019, the Company was notified by its litigation counsel that on December 28, 2018, the Suit was dismissed with prejudice by the filing of a Stipulation for Discontinuance in the New York State Supreme Court, New York County.

As of December 31, 2018 and 2017 the Company had net operating loss carryforwards for U.S. federal income tax purposes of approximately $230.0 million and $211.3 million respectively. A significant portion of the federal amount is subject to an annual limitation as low as $27,500 as a result of changes in the Company’s ownership in May 2003, November 2016, and multiple dates throughout 2017 and 2018, as defined by Federal Internal Revenue Code Section 382 and the related income tax regulations. As a result of the limitations caused by the May 2003, November 2016 and multiple 2017 and 2018 ownership changes, approximately $208.1 million of the total net operating loss carryforwards is expected to expire unutilized and will be unavailable to offset future federal taxable income. Approximately $21.9 million of net operating loss carryforwards remains available to offset future federal taxable income, of which $1.7 million will expire between 2019 and 2037 and $20.2 million will have an unlimited carryforward period as a result of the Tax Cuts and Jobs Act.

In addition, the Company’s state net operating losses are also subject to annual limitations that generally follow the federal Section 382 provisions (with the exception of Connecticut), adjusted for each state’s respective income apportionment percentages. As of December 31, 2018 and 2017, the Company had net operating loss carryforwards for state and city income tax purposes between approximately $27.3 million and $167.3 million and between approximately $27.3 million and $150.3 million, respectively, which expire through 2038. As a result of the 382 limitations, approximately $157.2 million and $141.5 million of New York State and New York City net operating losses are expected to expire unutilized and will be unavailable to offset future taxable income. Approximately $10.1 million and $10.1 million of net operating loss carryforwards, respectively, will be available to offset future state and city taxable income. As of December 31, 2018 and 2017 the Company had a net operating loss carryforward for foreign income tax purposes of $25.2 million and $25.0 million, respectively, which have indefinite carryforward periods. As of December 31, 2018 and 2017, the Company had federal research and development tax credit carryforwards of approximately $5.0 million and $4.3 million respectively, which expire through 2038. As a result of the section 382 limitations, all but $0.2 million of the tax credit carryforwards is expected to expire unutilized.

Management has established a 100% valuation allowance against the deferred tax assets as management does not believe it is more likely than not that these assets will be realized. The Company’s valuation allowance decreased by approximately $5.4 million and decreased by $1.1 million in 2018 and 2017, respectively. The change in valuation allowance is as follows:

On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act (the “Act”). The Act, which is also commonly referred to as “U.S. tax reform”, significantly changes U.S. corporate income tax laws by, among other provisions, reducing the maximum U.S. corporate income tax rate from 35% to 21% starting in 2018. During the year ended December 31, 2017, the Company reduced deferred tax assets by a provisional amount of $143,500, offset by a corresponding reduction to its valuation allowance, as a result of there-measurement of deferred tax assets and liabilities from its 34% effective rate under existing law to the new lower statutory rate of 21%. The Company finalized its accounting of the effects of tax reform in 2018, which resulted in insignificant adjustments.

The Act also requires a mandatoryone-time inclusion of the deferred foreign income of controlled foreign corporations. Theone-time transition tax is based on Delcath’s total post-1986 earnings and profits (E&P) for which the Company has previously deferred from U.S. income taxes. During the year ended December 31, 2017, the Company’s reasonable estimate resulted in no provisional amount for theone-time transition tax liability, as the Company’s international subsidiaries are expected to have a cumulative deficit in E&P. As the Company’s international subsidiaries have a cumulative deficit in earnings and profits, the Company did not anticipate being affected by the mandatory inclusion provisions of the Act. The Company finalized its calculation of the total post-1986 foreign E&P (including deficits) for these foreign subsidiaries during 2018 and was not impacted by the mandatory inclusion provisions of the Act.

On December, 22, 2017, Staff Accounting Bulletin 118 was issued due to the complexities involved in accounting for the recently enacted Act. SAB 118 requires the Company to include in its financial statements a reasonable estimate of the impact of the Act on earnings to the extent such estimate has been determined. Accordingly, the U.S. provision for income tax for December 31, 2017 was based on the reasonable estimate guidance provided by SAB 118. The Company finalized the impact from the Act and recorded insignificant adjustments.

The Company complies with the provisions of ASC740-10, Income Taxes, in accounting for its uncertain tax positions. ASC740-10 addresses the determination of whether tax benefits claimed or expected to be claimed on a tax return should be recorded in the financial statements. Under ASC740-10, the Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The Company has determined that the Company has no significant uncertain tax positions requiring recognition under ASC740-10 and therefore has not included a tabular rollforward of unrecognized tax benefits. As there are no uncertain tax positions recognized, interest and penalties have not been accrued.

The Company is subject to income tax in the U.S., as well as various state and international jurisdictions. The Company has not been audited by any state tax authorities in connection with income taxes. The Company has not been audited by international tax authorities or any states in connection with income taxes. The Company’s New York State tax returns have been subject to annual desk reviews which have resulted

F-26

in insignificant adjustments to the related franchise tax liabilities and credits. The Company is no longer subject to federal and state examination for tax years ending prior to December 31, 2015; tax years ending December 31, 2015 through December 31, 2018 remain open to examination. The Republic of Ireland is the Company’s only significant foreign jurisdiction. The Company is no longer subject to Ireland tax examination for tax years ending prior to December 31, 2014 (as Ireland has not initiated an audit of 2013 as of December 31, 2018); tax years ending December 31, 2014 through December 31, 2018 remain open to examination. However, the Company’s tax years December 31, 1998 through December 31, 2018 generally remain open to adjustment for all federal, state and foreign tax matters until its net operating loss and tax credit carryforwards are utilized or expire prior to utilization, and the applicable statutes of limitation have expired in the utilization year. The federal and state tax authorities can generally reduce a net operating loss (but not create taxable income) for a period outside the statute of limitations in order to determine the correct amount of net operating loss which may be allowed as a deduction against income for a period within the statute of limitations.

Delcath recognizes interest accrued related to unrecognized tax benefits and penalties, if incurred, as a component of income tax expense.

SUBSEQUENT EVENTS

Since January 1, 2019, the Company has issued 11,285 shares pursuant to exercises ofPre-Funded Series D Warrants.

As previously reported, in January 2019, the Company terminated Backstop Commitment Purchase Agreements with four institutional investors, by their mutual agreement. The Company and such institutional investors entered into Backstop Commitment Purchase Agreements in connection with a rights offering conducted by the Company that closed in September 2018 in which the Company proposed to raise up to $50 million by distributing, at no charge, to holders of its Common Stocknon-transferable rights to subscribe for and purchase shares of the Company’s Common Stock at a price of $1,225 per share (the “Subscription Price”). Pursuant to the Backstop Commitment Purchase Agreements, such institutional investors agreed to purchase, at the Subscription Price, shares not issued in the rights offering following the expiration of the rights offering subscription period, subject to certain conditions, including the requirement that the closing price of a share of the Company’s Common Stock as reported by the OTCQB or higher market for each of the five business days immediately preceding a purchase exceeded the Subscription Price. The Backstop Commitment Purchase Agreements were terminated by mutual agreement of the parties thereto due to the fact that the closing price of the Company’s Common Stock had not exceeded the Subscription Price since October 1, 2018 and, thus, the institutional investors had no obligation to purchase shares.

On March 29, 2019, the Company exchanged all of its Series D Preferred Stock (with a stated value of $1,160,000) and received $400,000 in proceeds and issued a senior secured promissory note to an investor with a principal amount of $1,560,000. The note is due on April 1, 2020, bears interest at 8% per annum and is nonconvertible.

On April 19, 2019, April 26, 2019, May 9, 2019 and May 23, 2019, the Company borrowed an aggregate $3.3 million from two institutional investors and issued promissory notes to the investors. The promissory notes have an aggregate principal amount of $3.3 million, bear interest at the rate of 8% per annum and are due six months from the issuance of each note. The promissory notes are nonconvertible. The notes contain standard events of default and remedies therefor. The Company’s obligations under the promissory notes to the institutional investor are secured by a lien on the Company’s assets.

On June 6, 2019, the Company entered into an agreement with two institutional investors, pursuant to which the investors agreed to transfer and surrender to the Company for cancellation of 5,605 Series D Warrants and 0.1 millionPre-Funded Series D Warrants. Under the terms of the Purchase Agreement, the investors agreed to defer the payment of the purchase price for the Series D Warrants andPre-Funded Series D

F-27

Warrants and, accordingly, the Company agreed to sell and issue to the investors 8% Senior Secured Promissory Notes in an aggregate principal amount of $2.0 million in full payment and satisfaction of the purchase price for the Series D Warrants andPre-Funded Series D Warrants.

On December 24, 2019, the Company effected a reverse stock split at which time Delcath’s common stock began trading on the OTCQB on aone-for-seven hundred (1:700) split-adjusted basis. All owners of record as of the open of the OTCQB market on December 24, 2019 received one issued and outstanding share of Delcath common stock in exchange for seven hundred outstanding shares of Delcath common stock. No fractional shares were issued in connected with the reverse stock split. All fractional shares created by theone-for-seven hundred exchange were rounded up to the next whole share. The reverse stock split had no impact on the par value per share of Delcath common stock, which remains at $0.01. All current and prior period amounts related to shares, share prices and earnings per share, presented in the Company’s consolidated financial statements and the accompanying Notes have been restated to give retrospective presentation for the reverse stock split.

Notes to the Condensed Consolidated Financial Statements

(1)

GENERAL

The unaudited interim condensed consolidated financial statements of Delcath Systems, Inc. (“Delcath” or the “Company”) as of and for the three and nine months ended September 30, 2019 and 2018 should be read in conjunction with the consolidated financial statements included in the Company’s Annual Report on Form10-K for the fiscal year ended December 31, 2018 (the “Annual Report”), which was filed with the Securities Exchange Commission (the “SEC”) on June 14, 2019 and may also be found on the Company’s website (www.delcath.com). In these notes to the condensed consolidated financial statements the terms “us”, “we” or “our” refer to Delcath and its consolidated subsidiaries.

Description of Business

Liquidity and Operating Matters

The accompanying interim condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company has incurred losses since inception and expects to continue incurring losses for the next several years. These losses, among other factors, raise substantial doubt about the Company’s ability to continue as a going concern.

The Company’s existence is dependent upon management’s ability to obtain additional funding sources or to enter into strategic alliances. There can be no assurance that the Company’s efforts will result in the resolution of the Company’s liquidity needs. The accompanying statements do not include any adjustments that might result should the Company be unable to continue as a going concern.

Basis of Presentation

These interim condensed consolidated financial statements are unaudited and were prepared by the Company in accordance with generally accepted accounting principles in the United States of America (GAAP) and with the SEC’s instructions to Form10-Q and Article 10 of RegulationS-X. They include the accounts of all entities controlled by Delcath and all significant inter-company accounts and transactions have been eliminated in consolidation.

The preparation of interim condensed consolidated financial statements requires management to make assumptions and estimates that impact the amounts reported. These interim condensed consolidated financial statements, in the opinion of management, reflect all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of the Company’s results of operations, financial position and

F-34

cash flows for the interim periods ended September 30, 2019 and 2018; however, certain information and footnote disclosures normally included in our Annual Report have been condensed or omitted as permitted by GAAP. It is important to note that the Company’s results of operations and cash flows for interim periods are not necessarily indicative of the results of operations and cash flows to be expected for a full fiscal year or any interim period.

Significant Accounting Policies

A description of our significant accounting policies has been provided in Note 3 Summary of Significant Accounting Policies to the Consolidated Financial Statements included in the Company’s Annual Report filed for the fiscal year ended December 31, 2018.

Derivative Financial Instruments

The accounting treatment of derivative financial instruments requires that the Company record financial instruments at their fair value as of the inception date of the agreement and at fair value as of each subsequent balance sheet date. Any change in fair value is recorded asnon-operating,non-cash income or expense for each reporting period at each balance sheet date. The Company reassesses the classification of its derivative instruments at each balance sheet date. If the classification changes as a result of events during the period, the contract is reclassified as of the date of the event that caused the reclassification. As a result of issuing such instruments the Company has adopted a sequencing policy in accordance with ASC815-40-35-12 whereby all future instruments may be classified as a derivative liability with the exception of instruments related to share-based compensation issued to employees. However, the Company has recognized the Series E Preferred Stock and SeriesE-1 Preferred Stock issued in July 2019 and August 2019 as equity because the agreements related to the issuance of those instruments specifically state that the common shares underlying the Preferred Stock take priority in registration. Additionally, the Company has a sufficient number of authorized shares for the issuance of common shares upon the conversion of the Preferred Stock. The Company did not have sufficient authorized shares to settle the associated warrants and accordingly has classified such warrants as a liability in the accompanying financial statements.

Recently Adopted Accounting Pronouncements

In February 2018, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”)2018-02, Income Statement—Reporting Comprehensive Income (Topic 220). ASU2018-02 allows a company to elect a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act. ASU2018-02 is effective for periods beginning after December 15, 2018. Upon adoption of ASU2018-02, the Company did not elect to reclassify the tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings, as the stranded tax effects were insignificant.

In February 2016, the FASB issued ASU2016-02, Leases (Topic 842) effective January 1, 2019, electing the practical expedients and applying the transition provisions as of the effective date. Reporting periods beginning on or after January 1, 2019 are presented under Topic 842, while prior period amounts, as reported under previous GAAP, were not adjusted. The adoption of Topic 842 on January 1, 2019 did not have a significant impact on the Company’s consolidated results of operations or cash flows.

LEASES

The Company recognizesright-of-use (“ROU”) assets and lease liabilities when it obtains the right to control an asset under a leasing arrangement with an initial term greater than twelve months. The Company leases its facilities undernon-cancellable operating and financing leases.

The Company evaluates the nature of each lease at the inception of an arrangement to determine whether it is an operating or financing lease and recognizes the ROU asset and lease liabilities based on the present value of future minimum lease payments over the expected lease term. The Company’s leases do not generally contain an implicit interest rate and therefore the Company uses the incremental borrowing rate it would expect to pay to borrow on a similar collateralized basis over a similar term in order to determine the present value of its lease payments.

OUTSTANDING DEBT

On June 6, 2019, the Company entered into an agreement with two institutional investors, pursuant to which the investors agreed to transfer and surrender to the Company for cancellation of warrants to purchase 5,605 shares of the Company’s common stock (the “Series D Warrants”) and warrants to purchase 0.1 million shares of the Company’s common stock (the“Pre-Funded Series D Warrants”). Under the terms of the Purchase Agreement, the Company agreed to sell and issue to the investors 8% Senior Secured Promissory Notes in an aggregate principal amount of $2.0 million in full payment and satisfaction of the purchase price for the Series D Warrants andPre-Funded Series D Warrants. This agreement was effective on July 15, 2019, upon the closing of the Company’s Private Placement discussed further in Note 9. The principal is recognized in Convertible notes payable, long-term on the Condensed Consolidated Balance Sheet.

On April 19, 2019, April 26, 2019, May 9, 2019 and May 23, 2019, the Company issued 8% senior secured notes (collectively, the “2019 Notes”) in the aggregate principal amount of $3.3 million, to two institutional investors. The 2019 Notes bore interest at the rate of 8% per annum and were to mature on thesix-month anniversary of issuance in each case. The 2019 Notes were not convertible. The 2019 Notes contained standard events of default and remedies and are secured by a lien on the Company’s assets. The 2019 Notes were exchanged as part of the recent equity financing discussed further in Note 9 and are no longer outstanding.

In March 2019, the Company exchanged all issued and outstanding shares of its Series D Preferred Stock (having an aggregate stated value of $1,160,000) and received $400,000 in cash proceeds in exchange for a senior secured promissory note (the “March 2019 Note”) in the principal amount of $1,560,000. The March

F-38

2019 Note bore interest at the rate of 8% per annum, and were to mature on April 1, 2020, and was not convertible. The March 2019 Note was exchanged as part of the recent equity financing discussed further in Note 9 and is no longer outstanding.

On June 4, 2018, July 21, 2018, August 29, 2018, and September 21, 2018, the Company issued 8% senior secured convertible notes (collectively, “the 2018 Notes”) in the aggregate principal amount of $9.4 million to several institutional investors. The 2018 Notes bore interest at the rate of 8% per annum and had maturity dates between December 2018 and March 2021. The 2018 Notes were initially convertible and secured pursuant to a Security Agreement which created a first priority security interest in all of the personal property (other than Excluded Collateral as defined in the Security Agreement) of the Company of every kind and description, tangible or intangible, whether currently owned and existing or created or acquired in the future. In March 2019, the Company amended the June 2018, July 2018 and August 2018 Notes to make themnon-convertible. There was no impact to the financial statements. In April 2019, the Company received notices of default from the investors in the 2018 Notes which resulted in a 25%, or $1.1 million, increase in principal and an increase in the interest rates from 8% to 18%. The 2018 Notes were exchanged as part of the recent equity financing discussed further in Note 9 and are no longer outstanding.

The following tables provide a summary of the various notes issued at September 30, 2019 and December 31, 2018:

STOCKHOLDERS’ EQUITY

Preferred Stock Issuances

Series E and SeriesE-1 Preferred Stock

On July 11, 2019, the Company and certain accredited investors entered into a securities purchase agreement pursuant to which the Company sold to investors an aggregate of 20,000 shares of Series E convertible preferred stock, par value $0.01 per share (the “Series E Preferred Stock”) at a price of $1,000 per share and a warrant (a “2019 Warrant”) to purchase a number of shares of common stock of the Company, equal to the number of shares of common stock issuable upon conversion of the Series E Preferred Stock purchased by the investor (the “July 2019 Private Placement”). The Company received gross proceeds from the July 2019 Private Placement of $20.0 million.

On August 19, 2019, the Company and certain accredited investors entered into a securities purchase agreement pursuant to which the Company sold to investors an aggregate of 9,510 shares of SeriesE-1 convertible preferred stock, par value $0.01 per share (the “SeriesE-1 Preferred Stock”) at a price of $1,000 per share and a warrant (a “2019 Warrant”) to purchase a number of shares of common stock of the Company equal to the number of shares of common stock issuable upon conversion of the SeriesE-1

F-39

Preferred Stock purchased by the investor (the “August 2019 Private Placement”). The Company received gross proceeds from the August 2019 Private Placement of $9.5 million.

Each share of Series E Preferred Stock and SeriesE-1 Preferred Stock (collectively, the “Preferred Stock”) is convertible at any time at the option of the holder into the number of shares of Common Stock determined by dividing the stated value by the conversion price of $25.36, subject to certain limitations and adjustments (the “Conversion Price”). Except for certain adjustments, the holders of the Preferred Stock are entitled to receive dividends on shares of Preferred Stock equal (on an “as converted” basis) to and in the same form as dividends paid on shares of the Common Stock. Any such dividends that are not paid to the holders of the Preferred Stock will increase the stated value. No other dividends will be paid on shares of Preferred Stock. Each Warrant has an exercise price equal to $25.36, subject to adjustment in accordance with the terms of the Warrants (the “Exercise Price”), and are exercisable at any time beginning on the date that the Company effects a reverse stock split until 5:00 p.m. (NYC time) on the date that is five years following the date that the Company effects a reverse stock split.

The Conversion Price and the Exercise Price may, upon each of (i) the third trading day following the date that the Company effects a reverse stock split, (ii) the date that the initial registration statement to be filed pursuant to the Registration Rights Agreement (as further discussed below) is declared effective by the United States Securities and Exchange Commission (“SEC”), and (iii) in the event that all of the registrable securities (as defined in the Registration Rights Agreement) are not then registered on an effective registration statement, the date that all of the shares underlying the Preferred Stock and Warrants may be sold pursuant to Rule 144, be reduced, and only reduced, to equal the lesser of (x) the then effective Conversion Price or Exercise Price, as applicable, and (y) 90% of the average of the five daily volume weighted average prices of the Common Stock immediately prior to such dates. In the event of a reduction in the Exercise Price, the aggregate number of Warrant Shares shall be increased such that the aggregate Exercise Price of the Warrants on the day immediately following such reduction in the Exercise Price is equal to the aggregate Exercise Price immediately prior to such adjustment. In addition, from the date of issuance of the Preferred Stock and Warrants until such time that the Company’s Common Stock is listed or quoted on a national exchange, the Conversion Price and the Exercise Price are subject to price-based anti-dilution protections.

The Company received net proceeds after expenses of $26.5 million. As discussed further in Note 8, the Company exchanged $11.8 million of debt, interest and Series D Warrants for 11,500 shares of Series E Preferred Stock and related warrants. The Company also exchanged $0.1 million in accounts payables for 149 shares of Series E Preferred Stock and related warrants and issued 923 shares of Series E Preferred Stock and related Warrants to certain investors in exchange for a waiver of rights under exchange agreements signed in December 2018 and March 2019. Of the net proceeds and equitized value received, the Company allocated an estimated fair value of $20.8 million to the 2019 Warrants. As a result of the Series E Preferred Stock and SeriesE-1 Preferred Stock having an effective conversion price that was lower than the market price on the date of issuance, the Company has recognized a beneficial conversion feature of $18.3 million. Due to the Series E Preferred Stock and SeriesE-1 Preferred Stock being immediately convertible, the beneficial conversion feature was recognized in full as a deemed dividend.

Series D Preferred Stock

On November 5, 2018, the Company’s Board authorized the establishment of a new series of preferred stock designated as Series D Preferred Stock, $0.01 par value, the terms of which are set forth in the certificate of designations for such series of Preferred Stock. On March 29, 2019, the Company exchanged all issued and outstanding shares of its Series D Preferred Stock (having an aggregate stated value of $1,160,000) and received $400,000 in cash proceeds in exchange for the issuance of the March 2019 Notes. Please see the discussion under Note 8 above.

Common Stock Issuances

During the nine months ended September 30, 2019 the Company issued 11,285 shares of the Company’s common stock pursuant to the exercise ofPre-Funded Series D Warrants that were issued in connection with the 2018 Notes discussed in Note 8 above.

Warrant Exchange

In April 2019, the Company entered into an exchange agreement with an institutional investor with respect to warrants held by such investor (the “February 2018 Warrants”). The February 2018 Warrants were issued to several institutional investors as part of the Company’s February 2018 sale of the Company’s common stock and the issuance of warrants to purchase common shares. Pursuant to the exchange agreement, the Company issued 92 shares of the Company’s common stock (the “Exchange Shares”) in exchange for the February 2018 Warrants. The exchange resulted in a loss of approximately $6,000 which is recognized in the statement of operations.

Share-Based Compensation

The Company’s 2019 Equity Incentive Plan (the “Plan”) allows for grants in the form of incentive stock options, nonqualified stock options, stock units, stock awards, stock appreciation rights, and other stock-based awards. All of the Company’s officers, directors, employees, consultants and advisors are eligible to receive grants under the Plan. The maximum number of shares reserved for issuance under the Plan is 2,142. Options to purchase shares of common stock are granted at exercise prices not less than 100% of fair value on the dates of grant. As of September 30, 2019, the Plan had approximately 502 shares available for grant.

The following is a summary of stock option activity under the Plan for the nine months ended September 30, 2019:


	Number of Shares			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term (Years)		Aggregate Intrinsic Value

NET LOSS PER COMMON SHARE

Basic net loss per share is determined by dividing net loss by the weighted average shares of common stock outstanding during the period, without consideration of potentially dilutive securities except for those shares that are issuable for little or no cash consideration. Diluted net loss per share is determined by dividing net loss by diluted weighted average shares outstanding. Diluted weighted average shares reflects the dilutive effect, if any, of potentially dilutive common shares, such as stock options and warrants calculated using the treasury stock method. In periods with reported net operating losses, all common stock options and warrants are generally deemed anti-dilutive such that basic net loss per share and diluted net loss per share are equal. However, in certain periods in which the exercise price of the warrants was less than the last reported sales price of Delcath’s common stock on the final trading day of the period and there is a gain recorded pursuant to the change in fair value of the warrant derivative liability, the impact of gains related to themark-to-market adjustment of the warrants outstanding at the end of the period is reversed and the treasury stock method is used to determine diluted earnings per share.

TAXES

As discussed in Note 14Income Taxes to the Consolidated Financial Statements included in the Company’s Annual Report filed for the fiscal year ended December 31, 2018, the Company has a valuation allowance against the full amount of its net deferred tax assets. The Company currently provides a valuation allowance against deferred tax assets when it is more likely than not that some portion or all of its deferred tax assets will not be realized. The Company has not recognized any unrecognized tax benefits in its balance sheet.

The Company is subject to income tax in the U.S., as well as various state and international jurisdictions. The federal and state tax authorities can generally reduce a net operating loss (but not create taxable income) for a period outside the statute of limitations in order to determine the correct amount of net operating loss which may be allowed as a deduction against income for a period within the statute of limitations. Additional information regarding the statutes of limitations can be found in Note 14Income Taxes to the Consolidated Financial Statements included in the Company’s Annual Report filed for the fiscal year ended December 31, 2018.

Waiver and Forbearance Agreement

Reverse Stock Split

Pursuant to the Company’s obligations under the July 2019 Private Placement and the August 2019 Private Placement, the Company presented a proposal for a reverse stock split at its Annual Meeting of Stockholders on September 17, 2019. On the same date, a majority of stockholders of the Company approved a proposal to approve and adopt an amendment to our Amended and Restated Certificate of Incorporation to effect a reverse stock split of our shares of common stock, $0.01 par value per share, issued and outstanding or reserved for issuance, at a specific ratio within a range from1-for-50 to1-for-1,200, inclusive, prior to the first anniversary of stockholder approval of the proposal, and to grant authorization to the Board of Directors to determine, in its sole discretion, whether to effect the reverse stock split, as well as its specific timing and ratio. Also on the same date, the Company’s Board of Directors adopted resolutions to effect as soon as reasonably practicable the reverse split of the issued and outstanding shares of the Common Stock at a ratio of1-for-100.

F-45

Following FINRA’s completion of its review of the Company’s Reverse Stock Split, on December 24, 2019, the Company effected a reverse stock split at which time Delcath’s common stock began trading on the OTCQB on aone-for-seven hundred (1:700) split-adjusted basis. All owners of record as of the open of the OTCQB market on December 24, 2019 received one issued and outstanding share of Delcath common stock in exchange for seven hundred outstanding shares of Delcath common stock. No fractional shares were issued in connected with the reverse stock split. All fractional shares created by theone-for-seven hundred exchange were rounded up to the next whole share. The reverse stock split had no impact on the par value per share of Delcath common stock, which remains at $0.01. All current and prior period amounts related to shares, share prices and earnings per share, presented in the Company’s consolidated financial statements and the accompanying Notes have been restated to give retrospective presentation for the reverse stock split.

Preferred Stock conversions

From October 1, 2019 through November 14, 2019, the Company issued 5,286 shares of Common Stock to the holders of Series E and SeriesE-1 Preferred Stock pursuant to conversion notices submitted by the holders.

Item 14. Indemnification of Directors and Officers.

Section 102(b)(7) of Delaware’s General Corporation Law (“DGCL”) allows a corporation to provide in its certificate of incorporation that a director of the corporation will not be personally liable to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, except where the director breached the duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate law or obtained an improper personal benefit. Our amended and restated certificate of incorporation provides for this limitation of liability.

Section 145 of the DGCL, or Section 145, provides that a Delaware corporation may indemnify any person who was, is or is threatened to be made, party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his or her conduct was illegal. A Delaware corporation may indemnify any persons who are, were or are a party to any threatened, pending or completed action or suit by or in the right of the corporation by reason of the fact that such person is or was a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees) actually and reasonably incurred by such person in connection with the defense or settlement of such action or suit, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests, provided that no indemnification is permitted without judicial approval if the officer, director, employee or agent is adjudged to be liable to the corporation. Where an officer or director is successful on the merits or otherwise in the defense of any action referred to above, the corporation must indemnify him against the expenses which such officer or director has actually and reasonably incurred.

Section 145 further authorizes a corporation to purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the corporation or is or was serving at the request of the corporation as a director, officer, employee or agent of another corporation or enterprise, against any liability

II-1

asserted against him and incurred by him in any such capacity, or arising out of his or her status as such, whether or not the corporation would otherwise have the power to indemnify him under Section 145.

Our amended and restated bylaws provides that we must indemnify our directors and officers to the fullest extent permitted by the DGCL and must also pay expenses incurred in defending any such proceeding in advance of its final disposition upon delivery of an undertaking, by or on behalf of an indemnified person, to repay all amounts so advanced if it should be determined ultimately that such person is not entitled to be indemnified.

We have entered into indemnification agreements with certain of our executive officers and directors pursuant to which have agreed to indemnify such persons against all expenses and liabilities incurred or paid by such person in connection with any proceeding arising from the fact that such person is or was an officer or director of our company, and to advance expenses as incurred by or on behalf of such person in connection therewith.

The indemnification rights set forth above shall not be exclusive of any other right which an indemnified person may have or hereafter acquire under any statute, provision of our certificate of incorporation, our bylaws, agreement, vote of stockholders or disinterested directors or otherwise.

We maintain standard policies of insurance that provide coverage (1) to our directors and officers against loss rising from claims made by reason of breach of duty or other wrongful act and (2) to us with respect to indemnification payments that we may make to such directors and officers.

Item 15. Recent Sales of Unregistered Securities

In connection with each of the following unregistered sales and issuances of securities, except as otherwise provided below, the Company relied upon the exemption from registration provided by Section 4(a)(2) of the Securities Act of 1933, as amended, and Rule 506 of Regulation D promulgated thereunder for transactions not involving a public offering.

On June 6, 2016, the Company completed a private placement, exempt for registration purposes under Section 4(a)(2) of the Securities Act, of $35 million aggregate principal amount of senior secured convertible notes (the “Notes”) pursuant to a Securities Purchase Agreement dated June 6, 2016 (the “SPA”) between the Company and certain institutional investors as set forth in the Schedule of Buyers attached to the SPA, as described in the Company’s Form8-K filed with the Securities and Exchange Commission on June 7, 2016.

The Notes were issued at an 8 percent original issue discount to the principal amount of Notes (a purchase price of $920 for each $1,000 principal amount of Notes and related warrants) for aggregate proceeds of $32.2 million. The Notes did not bear any ordinary interest and provided that the Company repay the principal amount of the Notes in equal monthly installments beginning seven months after the original date of issuance.

The Company also issued warrants to purchase one additional share of common stock to such institutional investors concurrently with the issuance of the Notes. The Company repurchased all of such warrants for cash, effective as of March 31, 2017.

On June 29, 2017, our Board authorized the establishment of a new series of preferred stock designated as Series A Preferred Stock, $0.01 par value, the terms of which are set forth in the certificate of designations for such series of Preferred Stock (the “Series A Certificate of Designations”) which were filed with the State of Delaware on June 30, 2017 (together with any preferred shares issued in replacement thereof in accordance with the terms thereof, the “Series A Preferred Stock”). On July 2, 2017, we entered into an exchange agreement (the “Exchange”) with one of our investors which had purchased certain senior secured convertible notes (the “Notes”), convertible into shares of our common stock pursuant to a certain June 6, 2016 securities purchase agreement, of $4.2 million aggregate principal amount of such Notes for 4,200 shares of Series A Preferred Stock (the “Series A Preferred Shares”). The Exchange was made in reliance upon the exemption from registration

II-2

provided by Rule 3(a)(9) of the Securities Act of 1933, as amended. The Series A Preferred Shares were entitled to the whole number of votes equal to $4.2 million divided by $901,600 (the closing bid price on June 13, 2016, the date of issuance of the Notes as adjusted for the reverse stock split effected in July 2016,) or 5 votes. The Series A Preferred Stock had no dividend, liquidation or other preferential rights to our common stock, and each share of Series A Preferred Stock was redeemed for the amount of $0.01 on August 28, 2017.

On July 11, 2017, we entered into an Amended and Restated Securities Purchase Agreement (the “Amended Purchase Agreement”) with certain institutional investors for the sale by the Company of 2,360 shares of Series B Preferred Stock (the “Series B Preferred Stock”) at a purchase price of $1,000 per share, in a private placement. The aggregate gross proceeds for the sale of the Series B Preferred Stock was $2.0 million. The Company used the proceeds from the transaction for general corporate purposes. The restricted shares of Series B Preferred Stock had no registration rights and were not be eligible for legend removal for a period of at least six months from the date of closing. This Amended Purchase Agreement amends the July 5, 2017 Securities Purchase Agreement (the “Purchase Agreement”) into which we entered with certain institutional investors (the “Investors”) for the sale by the Company of 2,360 shares of Series B Preferred Stock in a registered direct offering. The Series B Preferred Stock was entitled to the whole number of votes equal to $2.0 million divided by $45,745 (the closing bid price on July 5, 2017, the date of sale of the Series B Preferred Stock), or 44 votes. The Series B Preferred Stock had no liquidation or other rights which are preferential to our common stock. The Series B Preferred Stock was redeemed for $2,360,000 in August 2017.

On August 28, 2017, the Company entered into a Restructuring Agreement (the “Agreement”) with one of the institutional investors (the “Investor”) who was a party to the SPA. As of the date the Agreement was entered into, the Investor held $11,444,637 aggregate principal amount of Notes of which there was $10,092,857 aggregate Restricted Principal, (as defined in the Notes) of Notes (the “Restricted Notes”), secured by such aggregate cash amount held in a collateral account of the Company in the same amount (the “Restricted Cash”) and (y) $1,351,780 principal of Notes (the “Unrestricted Notes”), (ii) 4,200 shares of Series A Preferred Stock and (iii) 2,006 shares of Series B Convertible Preferred Stock.

Pursuant to the Agreement, (a) on the date thereof the Company and the Investor took the following actions (the “Initial Restructuring”): (i) the Investor released restrictions on $1,650,000 of Restricted Cash (the “Initial Release”), (ii) the Investor consented to the use of additional Restricted Cash to effect redemptions of the Series A Preferred Shares and the Series B Preferred Shares, (iii) the Investor cancelled $1,200,000 aggregate principal of the Notes (such portion of the Notes, the “Cancellation Note”), (iv) the Company redeemed all the Series A Preferred Shares outstanding for a cash payment to the Investor of $4.20 and (v) the Company redeemed the Series B Preferred Shares for a cash payment to the Investor of $2,006,000 and (b) upon the consummation of a reverse stock split of our Common Stock of at least twenty to one (the “Reverse Stock Split Event”, and such date, the “Reverse Stock Split Date”) by September 15, 2017, the Company and the Investor shall have taken the following actions (the “Additional Restructuring”, and together with the Initial Restructuring, the “Restructuring”): (i) the Investor shall consent to the use of Restricted Cash to effect redemptions of $4,000,000 aggregate Restricted Principal of the Restricted Notes (such portion of the Restricted Notes, the “Redemption Notes”), (ii) the Company shall redeem the Redemption Notes for a redemption price of $6.4 million (the “Redemption Price”) and (iii) the Company shall exchange (the “Exchange”), pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended, $2,436,852.80 aggregate Restricted Principal of the Restricted Notes (such portion of the Restricted Notes, the “Exchange Notes”, and together with the Redemption Notes, the “Restructured Notes”) for new warrants to purchase 164 shares of its Common Stock (the “New Warrants”, as exercised, the “New Warrant Shares”). The New Warrants expire on the 42 month anniversary of the date of issuance and bear an exercise price of $85,750 per share (which shall be adjusted to the new lower purchase price per share if there is a subsequent “down round” financing). The Investor, in lieu of an exercise of the New Warrants pursuant to a cash payment of the aggregate exercise price of the number of New Warrants being exercised, may exercise the New Warrants, in whole or in part, by electing instead to receive upon such exercise two shares and one hundred and twenty-five thousandths of a share of the Company’s Common Stock for each Warrant Share exercised pursuant to this provision. The transactions set forth herein were being made in reliance

II-3

upon the exemption from registration provided by Rule 4(a)(2) of the Securities Act of 1933, as amended (the “1933 Act”) and Rule 144(d)(3)(ii) of the 1933 Act. As a result of not having effected a reverse stock split by September 15, 2017, the Additional Restructuring did not occur.

Amendment to Restructuring Agreement

As a result of the lack of requisite approval by Delcath stockholders for the Company’s proposed reverse stock split, the parties and the two investors in the Notes entered into an amendment to the August restructuring agreement on October 10, 2017 as follows: (i) on the date that the Company effects a reverse split of its common stock, (x) the Company will exchange, pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended, an aggregate principal amount of those notes equal to $279,015 for new warrants to purchase an aggregate of 183 shares of Common Stock, and the Company shall redeem all the Series C Preferred Shares then outstanding for a cash payment of $590,000 and (ii) upon the initial consummation, on or prior to December 15, 2017, by the Company of the offering contemplated by the registration statement on FormS-1 that was filed with the SEC on October 11, 2017 the following shall occur: (i) pursuant to Section 3(b) of the Restricted Notes, the Company shall be deemed (as adjusted downward by the Black-Scholes value of the warrants being issued in this offering) to have automatically, and irrevocably, adjusted the conversion price of the Notes to 200% of the purchase price of a share of our common stock in the offering contemplated by the registration statement, (ii) the maturity date (as defined in the notes) shall automatically be extended to the earlier to occur of (x) the first anniversary of the date of consummation of the offering contemplated by the registration statement and (y) December 30, 2018, (iii) until the earlier of (x) this maturity date and (y) the 75th calendar day after the date of consummation of the offering contemplated by the registration statement, all installments to be made under the notes shall be deemed automatically deferred with no conversions during that 75 day period, (iv) the Company agreed to redeem any portion of the outstanding notes at any time requested by either investor thereto with $7.3 million in cash to be reduced by $0.6 million to redeem the Series C Preferred Stock remaining in the restricted accounts with respect to the 2016 convertible notes and (v) the conversion floor price on the notes is $0.05 and not subject to adjustments.

On September 21, 2017, we entered into a securities purchase agreement (the “SPA”) with two of our investors which had purchased certain senior secured convertible notes (the “Notes”), convertible into shares of our common stock pursuant to a certain June 6, 2016 securities purchase agreement, of $0.5 million aggregate purchase price for 590 shares of Series C Preferred Stock (the “Series C Preferred Shares”). The purchase of the Series C Preferred Stock was made in reliance upon the exemption from registration provided by Rule 4(a)(2) of the Securities Act of 1933, as amended. The Series C Preferred Shares was entitled to 2,121 votes and could only vote on approval of a reverse split of our outstanding common stock. The Series C Preferred Stock had no dividend, liquidation or other preferential rights to our common stock, and each share of Series C Preferred Stock was redeemable for the amount of $1,000.00, payable in cash, per share at our written election, and had to be redeemed by us no later than December 21, 2017. The Series C Preferred Stock was redeemed for $590,000 in November 2017.

On November 15, 2017, Delcath Systems, Inc. (the “Company”) entered into exchange agreements (“Exchange Agreements”) with each of the two investors from its June 2016 private placement of senior secured convertible notes as contemplated by that certain Securities Purchase Agreement, dated June 6, 2016, by and among the Company and such investors. As of November 15, 2017, those investors held $11,157,970 aggregate principal amount of investor notes (the “Investor Notes”), including (a) such aggregate principal amount of the Investor Notes as set forth on the signature page of the Investor hereto that does not include Restricted Principal as of the date hereof and all accrued and unpaid interest under the Investor Notes (such portion of the Investor Notes, the “Unrestricted Investor Notes”) and such aggregate principal amount of the Investor Notes as set forth on the signature page of the investors hereto that solely consists of Restricted Principal as of the date hereof (such portion of the Investor Notes, the “Restricted Investor Notes”).

On November 15, 2017, the Company authorized a new series of senior secured convertible notes of the Company, in the aggregate original principal amount as set forth above (the “Exchange Notes”), which Exchange

II-4

Notes shall be convertible into shares of Common Stock in accordance with the terms of the Exchange Notes. Subject to the terms and conditions of the Exchange Agreements, the Company and the investors exchanged (the “Exchange”) the Unrestricted Investor Notes for (a) $10,562,425 aggregate principal amount of the Exchange Notes (the “New Notes”, and the shares of Common Stock issuable pursuant to the terms of the New Notes, including, without limitation, upon conversion or otherwise, collectively, the “New Conversion Shares”) and (b) warrants to purchase an aggregate of 10,000 shares of Common Stock (the “New Warrants”, as exercised, the “New Warrant Shares”).

The New Conversion Shares and the New Warrant Shares are collectively referred to herein as the “New Underlying Securities” and, together with the New Notes and the New Warrants, the “New Securities”.

The New Notes, which were satisfied in full on December 28, 2017, bore the following terms:

•

The New Notes did not bear interest except upon the occurrence of an event of default upon which the interest rate is 15% per annum.

•

The initial conversion price was $1,050 per share for an optional conversion and at any time, an investor could have instead engaged in an alternate conversion for which the conversion price is 82% (75% if an event of default) of the lowest volume weighted average price for the Company’s common stock on the three trading days prior to and including the date of the conversion. All conversions attributable to the Restricted Notes could have been converted at the lower of the optional conversion price and the alternate conversion price, then in effect.

•

The obligation to prepay the Notes was extended to March 31, 2018, except in the case of an event of default or change in control.

•

Assuming equity conditions as stated in the New Notes are met, the investors would consent to release cash to the Company from the existing controlled accounts upon conversion of the New Notes.

•

The New Notes contained provisions waiving Section 8 of the Restricted Investor Notes, including, without limitation, any requirements for the Company to effect installment conversions or redemptions.

•

The New Notes contained customary and usual terms including but not limited to, events of default upon failure to trade on an eligible market, failure to timely deliver shares upon conversion, failure to maintain converted share reserve, for conversions, failure to make payments thereunder when due, failure to remove legends, cross defaults to other indebtedness, bankruptcy and the like, and any material adverse effect in the Company’s financial condition, as well as remedies and negative covenants substantially similar to those in the Investor Notes.

The New Warrants bear the following terms:

•

The Warrants will be exercisable for five years from the date of issuance.

•

The initial exercise price of the warrants is 115% of the closing bid price of the Company’s common stock as of the trading day ended immediately prior to the time of execution of the Exchange Agreement.

•

The Warrants contain full antidilution ratchet protection from lowered price securities issuances subsequent to the date of issuance for six months from the date of issuance and most favored nations protection for a year from the date of issuance.

•

The Warrants are exercisable on a cashless basis to the extent at any time commencing on the one year anniversary of the date of issuance the issuance of underlying securities is not covered by an effective registration statement.

•

To the extent the investors elect to apply any amounts in their controlled accounts to the balances of the New Notes, the number of shares into which the applicable New Warrant is exercisable shall be reduced by a formula set forth in the New Warrants.

II-5

On December 28, 2017, we entered into exchange agreements (collectively, “Exchange Agreements”), each by and between us and an investor from its June 2016 private placement of senior secured convertible notes (as further exchanged, the “Notes”) originally issued pursuant to that certain Securities Purchase Agreement, dated June 6, 2016, by and among us and such investors. Pursuant to the Exchange Agreements, we (i) extinguished our remaining $3,027,408 in outstanding obligations under the Notes in full, (ii) obtained a release of restrictions on $2,046,897.66 in restricted cash held in our control accounts, (iii) issued to the investors shares (the “Shares”) of our common stock (or rights (“Rights”) to receive common stock to the extent such issuance of Shares would otherwise result in the beneficial ownership by any such investor of more than 4.9% or 9.9% of our issued and outstanding stock), as applicable, of an aggregate of 0.1 million shares of our common stock (in each case, subject to trading restrictions set forth in leak out agreements we separately entered into with each investor (collectively, the“Leak-Out Agreements”)) and (iv) a cash payment to the investors of $829,830.54 from the restricted cash held in our control accounts. The number of shares of our issued and outstanding common stock immediately following issuance of the Initial Shares to the investors is 0.2 million.

The Rights could be exercised in whole or in part by an investor, without payment of additional consideration, at any time an investor would not beneficially own more than 4.9% or 9.9% (as set forth in the applicable Exchange Agreement) of our common stock (along with any shares of our common stock owned by any Attribution Parties) outstanding immediately after giving effect to such exercise. The Shares and Rights were issued in transactions exempt from registration under Section 4(a)(2) of the Securities Act of 1933, as amended, and the Shares and Rights were also issued in compliance with Section 3(a)(9) thereunder such that for Rule 144 purposes the holding period for the Shares and Rights and shares of our common stock underlying the Rights may be tacked onto the holding period of the Notes.

June 2018, July 2018 and August 2018 Notes

In June 2018, the Company entered into a Securities Purchase Agreement (the “June 2018 SPA”) with an institutional investor pursuant to which the Company issued $3.3 million in principal face amount of senior secured convertible notes of the Company (the “June 2018 Notes”) and related June 2018 Series D Warrant and June 2018Pre-Funded Series D Warrants (the “June 2018 Series D Warrants”) to purchase additional shares of the Company’s common stock. June 2018 Notes in the amount of $3.3 million and June 2018Pre-Funded Warrants in the amount of $0.2 million were issued for cash proceeds of $2.4 million with an original issue discount in the amount of $1.1 million. The June 2018 Notes bear 8% interest payable upon maturity. Of the $3.3 million in issued June 2018 Notes, $2.5 million matures in six months; the balance of $0.8 million is payable in twelve installments beginning seven months after the original issuance date. Each payment shall be paid in cash or, provided that the Market Price (as defined in the June 2018 SPA) is at least the conversion price of $2,100, at the option of the Company, upon ten Trading Days’ written notice to the Holder, in free trading common stock at the conversion price. The transaction was exempt from registration under Regulation S, as amended promulgated under the Securities Act of 1933.

On July 20, 2018, pursuant to another Securities Purchase Agreement between the Company and a domestic institutional investor, the Company sold two 8% Senior Secured Convertible Promissory Notes for a total face amount of $2,223,525 and a purchase price of $1,507,557 to this institutional investor upon the same terms and conditions as the transaction consummated under the Securities Purchase Agreement in a transaction exempt from registration under Section 4(a)(2) and Regulation D, as amended promulgated under the Securities Act of 1933.

Effective August 31, 2018, the Company entered into an agreement to sell up to $6.0 million purchase price of its 8% Senior Secured Convertible Promissory Notes (“Notes”) and warrants and prepaid warrants (“Warrants”) pursuant to a Securities Purchase Agreement (“Agreement”) with one or more institutional investors in transactions exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended (the “Securities Act”), Regulation S and Rule 506(b) promulgated thereunder. The Agreement provided for an aggregate subscription amount for all securities to all purchasers of up to $6.0 million and has substantially the

II-6

same terms as the July 20, 2018 Securities Purchase Agreement with Discover Growth Fund, LLC, except that the conversion price under the Notes and exercise price of the Warrants is $1,225, and interest on the Notes shall accrue and be payable at maturity. On August 31, 2018, the Company sold $3,336,617 face amount of Notes and 2,888 Warrants and33,968 Pre-funded Warrants to Discover Growth Fund, LLC with gross proceeds to the Company of $2,500,000.

On June 6, 2019, the Company entered into an agreement with two institutional investors, pursuant to which the investors agreed to transfer and surrender to the Company for cancellation of 39,234 Series D Warrants and 0.1 millionPre-Funded Series D Warrants. Under the terms of the Purchase Agreement, the investors agreed to defer the payment of the purchase price for the Series D Warrants andPre-Funded Series D Warrants and, accordingly, the Company agreed to sell and issue to the investors 8% Senior Secured Promissory Notes in an aggregate principal amount of $2.0 million in full payment and satisfaction of the purchase price for the Series D Warrants andPre-Funded Series D Warrants.

July 2019 Private Placement

On July 11, 2019, the Company and certain accredited investors (each an “Investor” and, collectively, the “Investors”) entered into a securities purchase agreement (the “Securities Purchase Agreement”) pursuant to which the Company expects to sell and issue to the Investors an aggregate of 20,000 shares of Series E Convertible Preferred Stock, par value $0.01 per share, at a price of $1,000 per share (the “Private Placement”). Pursuant to the Securities Purchase Agreement, the Company will issue to each Investor a warrant (a “Warrant”) to purchase a number of shares of common stock of the Company, par value $0.01 per share (“Common Stock”), equal to the number of shares of Common Stock issuable upon conversion of the Series E Preferred Stock purchased by the Investor. Each Warrant will have an exercise price equal to $25.36, subject to adjustment in accordance with the terms of the Warrants (the “Exercise Price”), and be exercisable at any time beginning on the date that the Company effects a reverse stock split until 5:00 p.m. (NYC time) on the date that is five years following the date that the Company effects a reverse stock split.

Item 17. Undertakings

The undersigned registrant hereby undertakes:

1. To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

To include any prospectus required by section 10(a)(3) of the Securities Act;

ii.

To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Securities and Exchange Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement.

iii.

To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement,provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or 15(d) of the Exchange Act that are incorporated by reference in the registration statement.

2. That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

3. To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

4. That, for the purpose of determining liability under the Securities Act to any purchaser:

If the registrant is relying on Rule 430B (Section 430B of this chapter):

Each prospectus filed by the registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5), or (b)(7) as part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii), or (x) for the purpose of providing the information required by section 10(a) of the Securities Act shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which that prospectus relates, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such effective date; or

ii.

If the registrant is subject to Rule 430C, each prospectus filed pursuant to Rule 424(b) as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B or other than prospectuses filed in reliance on Rule 430A, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

5. That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities: The undersigned registrant undertakes that in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424;

ii.

Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

iii.

The portion of any other free writing prospectus relating to the offering containing material information about the undersigned registrant or its securities provided by or on behalf of the undersigned registrant; and

iv.

Any other communication that is an offer in the offering made by the undersigned registrant to the purchaser.

6. Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.
