Notes to the Unaudited Condensed Consolidated Financial Statements

(amounts in thousands, except share and per share amounts)

(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, 2024 and 2023 should be read in conjunction with the audited consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023 (the “Annual Report”), which was filed with the Securities and Exchange Commission (the “SEC”) on March 26, 2024 and may also be found on the Company’s website (www.delcath.com). In these notes to the interim condensed consolidated financial statements the terms “us”, “we” or “our” refer to Delcath and its consolidated subsidiaries.

Description of Business

The Company is an interventional oncology company focused on the treatment of cancers primary or metastatic to the liver. The Company’s lead product, the HEPZATOTM KIT (melphalan for Injection/Hepatic Delivery System), a drug/device combination product, was approved by the US Food and Drug Administration (the “FDA”) on August 14, 2023, indicated as a liver-directed treatment for adult patients with uveal melanoma with unresectable hepatic metastases affecting less than 50% of the liver and no extrahepatic disease, or extrahepatic disease limited to the bone, lymph nodes, subcutaneous tissues, or lung that is amenable to resection, or radiation. The first commercial use of the HEPZATO KIT (“HEPZATO” or “HEPZATO KIT”) for the treatment of metastatic uveal melanoma (“mUM”) occurred in January 2024.

In the United States, HEPZATO is considered a combination drug and device product and is regulated as a drug by the FDA. Primary jurisdiction for regulation of HEPZATO has been assigned to the FDA’s Center for Drug Evaluation and Research. The FDA has granted Delcath six orphan drug designations (five for melphalan in the treatment of patients with ocular (uveal) melanoma, cutaneous melanoma, intrahepatic cholangiocarcinoma, hepatocellular carcinoma, and neuroendocrine tumor indications and one for doxorubicin in the treatment of patients with hepatocellular carcinoma).

The Company has sufficient raw material and component constituent parts of the HEPZATO KIT to meet anticipated demand and it intends to manage supply chain risk through stockpiled inventory and, where commercially reasonable, contracting with multiple suppliers for critical components.

In Europe, the hepatic delivery system is a stand-alone medical device having the same device components as HEPZATO, but without the melphalan hydrochloride and is approved for sale under the trade name CHEMOSAT Hepatic Delivery System for Melphalan (“CHEMOSAT”), where it has been used at major medical centers to treat a wide range of cancers in the liver. On February 28, 2022, CHEMOSAT received Medical Device Regulation (MDR) certification under the European Medical Devices Regulation (EU) 2017/745, which may be considered by jurisdictions when evaluating reimbursement.

To support the New Drug Application for HEPZATO the Company conducted the FOCUS Clinical Trial for Patients with metastatic hepatic dominant Uveal Melanoma (the “FOCUS Trial”), a global registration clinical trial that investigated objective response rate in patients with mUM. On May 6, 2024, the Company announced the publication of results from the pivotal FOCUS Trial in the journal Annals of Surgical Oncology. The current focus of the Company’s clinical development program is to generate clinical data for CHEMOSAT and HEPZATO either as monotherapy or in combination with immunotherapy. The Company expects that this will support increased clinical adoption of and reimbursement for CHEMOSAT in Europe, and to support reimbursement in various jurisdictions, including the United States. In addition to HEPZATO’s use to treat mUM, the Company believes that HEPZATO has the potential to treat other cancers in the liver, such as metastatic colorectal cancer, metastatic neuroendocrine tumors, metastatic breast cancer and intrahepatic cholangiocarcinoma, and plans to begin one or more studies of the HEPZATO KIT to treat such conditions in late 2024 or early 2025. The Company believes that those and similar disease states are areas of unmet medical needs that represent significant market opportunities.

Risks and Uncertainties

As detailed in the Company’s 2023 Annual Report filed on Form 10-K, the Company is subject to risks common to companies in the biopharmaceutical industry with FDA-approved products and planned clinical development activities, including, but not limited to, risks associated with successfully launching and commercializing the products; further developing HEPZATO to potentially treat other cancers in the liver and the Company’s ability to obtain any additional regulatory approval of such products in the United States and obtaining regulatory approval in other geographic markets;

Table of Contents

the uncertainty relating to the broad adoption of any approved products by physicians and consumers; and the impacts of significant competition.

In addition, high rates of inflation have previously resulted in the U.S. Federal Reserve raising interest rates and any future increases in interest rates, especially if coupled with reduced government spending and volatility in financial markets, may further increase economic uncertainty and heighten these risks. Furthermore, if additional banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, the Company or its partners’ ability to access existing cash, cash equivalents and investments may be threatened and could have a material adverse effect on the Company’s business and financial condition, including the Company’s ability to access additional capital on favorable terms, or at all, which could in the future negatively affect the Company’s ability to pursue its business strategy.

Liquidity and Going Concern

On September 30, 2024, the Company had cash and cash equivalents totaling $8.3 million and short-term investments totaling $5.7 million, as compared to cash, cash equivalents and restricted cash totaling $12.7 million and short-term investments totaling $19.8 million at December 31, 2023. During the nine months ended September 30, 2024, the Company used $17.7 million of cash in its operating activities and $8.6 million for principal payments.

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 or maintain profitability. The Company has historically funded its operations primarily with proceeds from sales of common stock, warrants and pre-funded warrants for the purchase of common stock, sales of preferred stock, proceeds from the issuance of convertible debt and borrowings under loan and security agreements.

If there is a substantial delay in the activation of additional sites to administer HEPZATO and/or the revenue generated from HEPZATO and CHEMOSAT is less than anticipated, the Company expects to need to raise additional capital under structures available to the Company, including debt and/or equity offerings, which may not be on favorable terms. In a substantially delayed site activation scenario, the Company would not have sufficient funds to meet its obligations within twelve months from the issuance date of these condensed consolidated financial statements. As such, there is uncertainty regarding the Company’s ability to maintain liquidity sufficient to operate its business effectively, which raises substantial doubt about the Company’s ability to continue as a going concern. Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting the Company’s ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If the Company raises funds through collaborations or other similar arrangements with third parties, it may have to relinquish valuable rights to its technologies, future revenue streams, research programs for product candidates and/or grant licenses on terms that may not be favorable to the Company, any of which may reduce the value of its common stock. If the Company is unable to raise additional funds through equity or debt financings when needed, it may be required to delay, limit, reduce or terminate its product development or future commercialization efforts or grant rights to develop and market its product candidates to third parties even if the Company would otherwise prefer to develop and market such product candidates itself.

The Company expects to use cash and cash equivalents to fund activities relating to commercial support for HEPZATO, CHEMOSAT and any future clinical research trials and operating activities. The Company’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 regulatory approvals and complying with applicable laws and 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; the resolution of any disputes with third parties; and the effect of competing technological and market developments.

The Company’s capital commitments over the next twelve months include (a) $6.8 million to satisfy accounts payable, accrued expenses, current lease liabilities and current medac settlement and (b) $2.0 million of convertible note principal payments, if the holders do not elect to convert the notes into equity. Additional capital commitments beyond the next twelve months include (a) $1.3 million of lease liabilities; and (b) $0.6 million for settlement of litigation with medac.

Basis of Presentation

Recent Accounting Pronouncements

No new accounting standards were adopted during the nine months ended September 30, 2024.

(2) Revenue

The Company recognizes product revenue from sales of HEPZATO in the United States and CHEMOSAT in certain European countries in accordance with the five-step model in Accounting Standards Codification (“ASC”) 606, Revenue Recognition: (i) identify contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenues when (or as) the Company satisfies the performance obligation. Under this revenue standard, the Company recognizes revenue when its customer obtains control of the promised goods, in an amount that reflects the consideration which the Company expects to receive in exchange for those goods.

HEPZATO

The Company ships and sells the HEPZATO KIT directly to hospitals and treating centers based on approved agreements. For certain customers, the inventory is considered on consignment in which the Company retains title to the product until the use of the HEPZATO KIT. For these sales, the Company recognizes HEPZATO revenue, based on contracted or published rates, upon completion of the procedure. There is no obligation for the hospitals or treating centers to use the consigned HEPZATO, and the Company has no contractual right to receive payment until the product is used in a procedure and transfer of control is completed. See Note 4 for further information for consignment inventory.

Hospitals and treating centers may also elect to purchase HEPZATO KITS prior to a procedure. For these sales, the purchasing hospital or treatment center obtains control of the product once it is delivered. In these instances, the Company recognizes the HEPZATO KIT revenue based on contracted rates stated in an approved contract or purchase order upon delivery to the customer. There are no contractual rights of returns, refunds or similar obligations.

CHEMOSAT

CHEMOSAT is sold directly to hospitals in the European Union and United Kingdom based on contracted rates in an approved contract or sales order. The Company recognizes product revenue from sales of CHEMOSAT upon shipment.

(8) Leases

The Company recognizes right-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 under non-cancellable operating 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

Table of Contents

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.

For both the three months ended September 30, 2024 and 2023, the Company recognized less than $0.1 million of operating lease expense, and $0.1 million and $0.3 million for the nine months ended September 30, 2024 and 2023, respectively.

In 2021, the Company entered into a sub-lease agreement (the “2021 Sub-Lease”) with its previous sub-lessee pursuant to which, effective August 2, 2021, the previous sub-lessee would become the lessee and the Company would then sublease its portion of the premises in Galway, Ireland from the previous sub-lessee. The Company’s annual rent expense under the 2021 Sub-Lease is less than $0.1 million for a term of 5 years.

In 2020, the Company entered into an amendment to a sub-lease agreement executed in 2016 for office space at 1633 Broadway, New York, New York. The term of the sub-lease agreement began in April 2016 and, pursuant to amendments, was extended through August 2023. As of August 31, 2023, the lease was month-to-month. No ROU assets or lease liabilities were recognized on the balance sheet as of December 31, 2023 for this arrangement. The Company ended the sublease for its former corporate offices at 1633 Broadway, New York, New York in February 2024.

On January 18, 2024, the Company entered into a lease agreement (the “Queensbury Lease”) to lease approximately 18,000 square feet of manufacturing and office space in Queensbury, New York (the “Premises”). The initial term of the lease is five years with a right to extend the lease by an additional five years, exercisable under certain conditions set forth in the Queensbury Lease. The Company’s annual rent expense under the Queensbury Lease is less than $0.2 million for a term of 5 years.

Term Loan from Avenue Venture Opportunities Fund, L.P.

On August 6, 2021, the Company entered into a Loan and Security Agreement (the “Avenue Loan Agreement”) with Avenue Venture Opportunities Fund, L.P. (the “Lender,” or “Avenue”) for a term loan in an aggregate principal amount of up to $20.0 million (the “Avenue Loan”). The Avenue Loan bore interest at an annual rate equal to the greater of (a) the sum of 7.70% plus the prime rate as reported in The Wall Street Journal and (b) 10.95%. The Avenue Loan matured on August 1, 2024 with a 16.20% rate at maturity.

The Avenue Loan Agreement required the Company to make and maintain representations and warranties and other agreements that are customary in loan agreements of this type. The Avenue Loan Agreement also contained customary events of default, including non-payment of principal or interest, violations of covenants, bankruptcy and material judgements. The Avenue Loan was secured by all of the Company’s assets globally, including intellectual property. As of August 2024, Avenue has released the Company from all obligations and returned all security interests back to the Company.

The initial tranche of the Avenue Loan was $15.0 million, including $4.0 million that was funded into a restricted account. On March 15, 2023, the Company returned to Avenue $4.0 million held as restricted cash to pay down a portion of the outstanding loan balance, principal payments of $2.1 million and an incremental 4.25% of the final payment of $0.2 million. On March 31, 2023, the Avenue Loan Agreement was amended (the “Avenue Amendment”) to defer the interest only period to September 30, 2023, with an additional extension option upon FDA Approval for the HEPZATO KIT and subsequent receipt of at least $10 million from the sale and issuance of equity securities. On August 14, 2023, the Company received FDA approval and had subsequently received over $10 million from the exercise of Tranche A Preferred Warrants. At the Company’s option, it elected to extend the interest only period to December 31, 2023 and monthly principal payments of approximately $1.0 million began in January 2024 with the final payment occurring on August 1, 2024.

Avenue did not exercise its option to convert the principal amount of the Avenue Loan into shares of the Company’s common stock.

In connection with the initial entry into the Avenue Loan Agreement, the Company issued warrants to Avenue (the “Initial Avenue Warrant”) to purchase 127,755 shares of common stock at an exercise price per share equal to $0.01. Additionally, in connection with the Avenue Amendment, the Company issued to Avenue a warrant to purchase 34,072 shares of common stock at an exercise price per share equal to $0.01. Avenue exercised all outstanding warrants connected to the Avenue Loan in full in April 2024.

The Company determined that the embedded conversion option associated with the Avenue Loan did not require bifurcation and met the criteria for equity classification. In addition, the amendment was recorded under debt modification guidance. Aggregate debt discount amortization of $0.1 million and $0.2 million was recorded during the three months ended September 30, 2024 and 2023, and $0.5 million and $0.6 million for the nine months ended September 30, 2024 and 2023, respectively. Interest expense incurred was $0.1 million and $0.3 million for the three months ended September 30, 2024 and 2023, respectively, and $0.4 million and $1.1 million for the nine months ended September 30, 2024 and 2023, respectively.

Convertible Notes Payable

The Company has $2.0 million of principal outstanding related to Senior Secured Promissory Notes (the “Rosalind Notes”) which bear interest at 8% per annum. Pursuant to the original terms, the Rosalind Notes were convertible into Series E Preferred Stock at a price of $1,500 per share and were to mature on July 16, 2021.

On August 6, 2021, the Company executed an agreement to amend the Rosalind Notes to (i) reduce the conversion price to $1,198 per share of the Company’s Series E Preferred Stock; and (ii) extend the maturity date to October 30, 2024. In addition, the holders of the Rosalind Notes agreed to subordinate all of the Company’s indebtedness and obligations to Avenue and all of the holders’ security interest to the Avenue Loan and Avenue’s security interest in the Company’s property.

The outstanding principal and accrued interest was paid on October 30, 2024. Rosalind did not exercise its option to convert the Rosalind Notes into shares of the Company’s common stock.

Interest expense accrued relating to the Rosalind Notes was $0.1 million for both the three and nine months ended September 30, 2024 and 2023.

(10) Preferred Purchase Agreement

On March 27, 2023, we entered into a securities purchase agreement with certain accredited investors (the “Preferred Purchase Agreement”), pursuant to which on March 29, 2023, the Company issued and sold, in a private placement (the “Series F Preferred Offering”), (i) 24,900 shares of Series F-1 Convertible Preferred Stock, par value $0.01 per share (the “Series F-1 Preferred Stock”), (ii) tranche A warrants (the “Preferred Tranche A Warrants”) to acquire 34,859 shares of Series F-3 Convertible Preferred Stock, par value $0.01 per share (the “Series F-3 Preferred Stock”) and (iii) tranche B warrants (the “Preferred Tranche B Warrants”, together with the Preferred Tranche A Warrant, the “Preferred Warrants”) to acquire 24,900 shares of Series F-4 Convertible Preferred Stock, par value $0.01 per share (the “Series F-4 Preferred Stock”) for an aggregate offering price of $24.9 million before deducting the fees paid to the placement agent and the financial advisors and other financing expenses payable by the Company.

The gross proceeds of $24.9 million from the Series F Preferred Offering have been allocated first to the Preferred Warrant liabilities at their fair value of $4.9 million, with the residual of $20.0 million being allocated to the Series F-1 Preferred Stock.

As of September 30, 2024, all of the Preferred Tranche A Warrants were exercised for an aggregate exercise price of $34.9 million and 250 Preferred Tranche B Warrants were exercised for an aggregate exercise price of $0.3 million. The remaining Preferred Tranche B Warrants are exercisable for 24,650 shares of Series F-4 Preferred Stock, with an aggregate exercise price of $24.7 million until the earlier of (i) 21 days following the Company’s announcement of receipt of at least $10 million in quarterly U.S. revenue from the commercialization of the HEPZATO KIT and (ii) March 31, 2026.

During the quarter ending September 30, 2024, we recorded at least $10 million in quarterly U.S. revenue from the commercialization of the HEPZATO KIT, which was announced by the Company on October 17, 2024, triggering the 21 day exercise period for the Tranche B Warrants. As of November 5, 2024, 24,900 Tranche B Warrants were exercised by the November 6, 2024 expiration date which resulted in $24.9 million of cash proceeds to the Company.

Pursuant to the Certificate of Designation of Preferences, Rights and Limitations of the Series F Convertible Voting Preferred Stock (the “Certificate of Designation”), each share of Series F-1 Preferred Stock automatically converted into shares of common stock and/or, if applicable (in accordance with the beneficial ownership limitations then in effect), shares of Series F-2 Preferred Stock, par value $0.01 per share (the “Series F-2 Preferred Stock” and, together with the Series F-1 Preferred Stock, the Series F-3 Preferred Stock and the Series F-4 Preferred Stock, the “Series F Preferred Stock”) in lieu of common stock. Subject to limitations set forth in the Certificate of Designation, the shares of Series F-2, F-3 and F-4 Preferred Stock are convertible into common stock at the option of the holder at the conversion price of $3.30 per share, $4.50 per share and $6.00 per share, respectively, rounded down to the nearest whole share, and in each case subject to the terms and limitations contained in the Certificate of Designation.

As of September 30, 2024, 58,924 shares of the Company’s Series F-1, F-2, F-3 and F-4 Preferred Stock were converted into 15,005,211 shares of common stock. As of September 30, 2024, there were 1,085 shares of Series F-2 Preferred Stock, and no shares of Series F-3 Preferred Stock or Series F-4 Preferred Stock outstanding.

The Series F-2, F-3 and F-4 Preferred Stock are not mandatorily redeemable, redeemable at the holder’s election or contingently redeemable at the holder’s election (at this point, a Deemed Liquidation Event would potentially trigger pro rata liquidation payments to the preferred and common stockholders on a pro rata “as converted” basis). Accordingly, the Series F-2, F-3 and F-4 Preferred are now classified as permanent equity.

The Company determined that the outstanding Preferred Warrants should be liability-classified. See Note 15 for a discussion of the accounting treatment of the Common Warrants and Preferred Warrants.

As of September 30, 2024, there have been 7,125,000 shares of common stock reserved under the 2020 Plan, which includes an additional 2,000,000 shares approved by shareholders on May 23, 2024 and registered on a Form S-8 registration statement, filed with the SEC on June 28, 2024, of which 2,232,925 remained available to be issued.

In addition to options granted from the 2020 Plan, the Company also grants employment inducement awards pursuant to Listing Rule 5635(c)(4) of the corporate governance rules of the Nasdaq Stock Market. The inducement grants are intended to provide incentive to certain individuals to enter into employment with the Company. Prior to December 5, 2023, the inducement awards were granted outside of the 2020 Plan, however they are governed in all respects as if they were issued under the 2020 Plan. These grants do not reduce the number of options available for issuance under the 2020 Plan.

On December 5, 2023, the Company’s 2023 Inducement Plan (the “2023 Plan”) was adopted by the Company’s Board of Directors. The 2023 Plan is administered by a Compensation Committee of two or more Independent Directors appointed by the Board of Directors and is intended to provide for the grant of non-qualified stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards, performance awards, as well as other stock-based awards or cash

awards that are deemed appropriate to incentivize employment with the Company. Awards from the 2023 Plan can only be granted to individuals who have not previously worked for the Company or have not worked for the Company for a bona fide period of time. As of September 30, 2024, there have been 650,000 shares of common stock reserved under the 2023 Plan, of which 285,000 remain available to be granted.

Employee Stock Purchase Plan

In August 2021, the Company’s Board of Directors, with shareholder approval in May 2022, adopted the Employee Stock Purchase Plan (the “ESPP”). The ESPP provides for a maximum of 260,295 shares of common stock to be purchased by participating employees of which 112,993 have been issued as of September 30, 2024 since the inception of the benefit in 2021. Employees who elect to participate in the ESPP will be able to purchase common stock at the lower of 85% of the fair market value of common stock on the first or last day of the applicable six-month offering period.

(12) Net Income (Loss) per Share

Basic net income or 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 income or loss per share is determined by dividing net income or 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, convertible preferred shares, and preferred and common warrants are generally deemed anti-dilutive such that basic net loss per share and diluted net loss per share are equal.

As of September 30, 2024 and 2023, the Company had 737,421 and 1,037,792 pre-funded warrants outstanding, respectively. The following table provides a reconciliation of the weighted average shares outstanding calculation for the three and nine months ended September 30, 2024 and 2023:

(13) Income Taxes

As discussed in “Note 17—Income Taxes” to the notes to the consolidated financial statements contained in the Annual Report, 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 17 - Income Taxes of the Company’s Annual Report.

The Inflation Reduction Act of 2022 included tax legislation that became effective in the first quarter of 2023. Significant legislation for corporate taxpayers includes a corporate alternative minimum tax of 15% for companies with $1 billion or more in average net financial statement profits over the three previous years, as well as a 1% indirect excise tax on the repurchase of shares by a publicly traded company. The Company does not expect this legislation to have an effect on the tax provision as of September 30, 2024, however the Company will continue to evaluate the effect on the tax provision each reporting period.

(14) Commitments and Contingencies

medac Matter

In April 2021, the Company’s wholly owned subsidiary, Delcath Systems Ltd, issued to medac GmbH, a privately held, multi-national pharmaceutical company based in Germany (“medac”), an invoice for a €1 million milestone payment under a License, Supply and Marketing Agreement dated December 10, 2018 (the “medac Agreement”) between medac and the Company. The medac Agreement provided to medac the exclusive right to market and sell CHEMOSAT in certain designated countries for which the Company was entitled to a combination of upfront and success-based milestone payments as well as a fixed transfer price per unit of CHEMOSAT and specified royalties.

In response to medac’s subsequent dispute and non-payment of the invoice, on October 12, 2021, the Company notified medac in writing that it was terminating the medac Agreement due to medac’s nonpayment of the €1 million milestone payment, with the effective date of termination of the medac Agreement being April 12, 2022. On December 16, 2021, the Company initiated an arbitration proceeding pursuant to the dispute resolution procedures of the medac Agreement for the non-payment of the invoice.

On December 30, 2022, the parties reached a final settlement of the matter and the Company agreed to pay medac either (a) a royalty on sales of CHEMOSAT units over a defined minimum for a period of five years or until a maximum payment has been reached, or (b) a minimum annual payment of $0.2 million in the event the annual royalty payment does not reach the agreed minimum payment amount. The first annual payment was made in May 2024 and the Company has estimated the remaining fair value of the settlement to be $0.8 million as of September 30, 2024 and recorded $0.6 million as other liabilities, non-current and $0.2 million as accrued expenses on the Company’s condensed consolidated balance sheet as of September 30, 2024.

Manufacturing and Supply Agreements

The Company has a License, Supply and Contract Manufacturing Agreement (as amended, the “Supply Agreement”) with Synerx Pharma, LLC and Mylan Teoranta for the supply of melphalan provided in the HEPZATO KIT. An amendment to the Supply Agreement was entered into on April 22, 2024, and effective as of May 1, 2024, which extends the term of the agreement through December 31, 2028, with an option to renew for successive five-year periods upon the mutual written consent of both parties. Although the Supply Agreement does not contain an annual minimum purchase quantity, the Agreement requires Delcath to order full lots of labeled melphalan vials. As of September 30, 2024, the Company has no commitments to purchase additional melphalan under this Supply Agreement in 2024.

(15) Fair Value Measurements

The table below presents activity within Level 3 of the fair value hierarchy, our liabilities carried at fair value for the nine months ended September 30, 2024:


	Level 3
(In thousands)	Contingent liabilities		Warrants		Total
Balance at January 1, 2024	$	996	$	5,548	$	6,544
Total change in foreign exchange	10		—		10
Warrant liability fair value adjustment	—		7,392		7,392
Change due to warrant exercise	—		(106)		(106)
Change due to liability payment	(221)		—		(221)
Balance at September 30, 2024	$	785	$	12,834	$	13,619

Contingent liabilities are re-measured to fair value each reporting period using projected financial targets, discount rates, probabilities of payment, and projected payment dates. Projected contingent payment amounts are discounted back to the current period using a discounted cash flow model. Projected financial targets are based on our most recent internal operational budgets and may take into consideration alternate scenarios that could result in more or less profitability for the respective service line. Increases or decreases in projected financial targets and probabilities of payment may result in significant changes in the fair value measurements. Increases in discount rates and the time to payment may result in lower fair value measurements. Increases or decreases in any of those inputs in isolation may result in a significantly lower or higher fair value measurement.

As disclosed in Note 10 and Note 11 of the Company’s consolidated financial statements, the Company allocated part of the proceeds of the Series F Preferred Offering to warrant liability issued in connection with the transaction. The valuations of the warrants were determined using option pricing models. The Company concluded that the Preferred Warrants were not in the scope of Accounting Standards Codification, Distinguishing Liabilities from Equity (ASC 480) since the Preferred Warrants are not mandatorily redeemable; and do not have obligations to issue a variable number of shares of preferred stock. The Company determined the Preferred Warrants met the definition of a derivative in accordance with ASC 815 but were not considered indexed to the Company’s common stock since the warrants require early settlement by repurchasing the preferred warrants for cash in an amount equal to the Black-Scholes value in the event of a Fundamental Transaction at pre-specified volatility of 100% as an input to the Black-Scholes calculation. The Company determined to record the Preferred Warrants at fair value with subsequent changes in fair value recorded in earnings at the end of each reporting period. For the three and nine months ended September 30, 2024, the Company recorded a decrease to other expense of $3.0 million and an increase to other expense of $7.4 million, respectively, related to the change in fair value of the warrant liability. These models use inputs such as the underlying price of the shares issued at the measurement date, volatility, risk free interest rate and expected life of the instrument. Historically, the Company has classified the warrants as a long-term liability due to potential provisions relating to the holders’ ability to exercise the warrants beyond twelve months of the reporting date. As of September 30, 2024, the warrants are classified as a short-term liability due to the accelerated expiration date of November 6, 2024.

The fair value of the preferred and common warrants at September 30, 2024 and December 31, 2023 was determined by using option pricing models assuming the following:


	September 30, 2024	December 31, 2023
Risk free interest rate	4.87%	4.09%
Expected term (years)	0.2	2.3
Expected volatility	61%	70%
Expected dividends	0.00%	0.00%

Additionally, the Company has determined that the warrant liability should be classified within Level 3 of the fair-value hierarchy by evaluating each input for the option pricing models against the fair-value hierarchy criteria and using the lowest level of input as the basis for the fair-value classification as called for in ASC 820. There are six inputs: closing price of the Company’s stock on the day of evaluation; the exercise price of the warrants; the remaining term of the warrants; the volatility of the Company’s stock along with comparable companies over that term; annual rate of dividends; and the risk-free rate of return. Of those inputs, the exercise price of the warrants and the remaining term are readily observable in the warrant agreements. The annual rate of dividends is based on the Company’s historical practice of not granting dividends. The closing price of the Company’s stock would fall under Level 1 of the fair-value hierarchy as it is a

Table of Contents

quoted price in an active market, the risk-free rate of return is a Level 2 input, while the historical volatility is a Level 3 input as defined in ASC 820-10. Since the lowest level input is a Level 3, the Company determined the warrant liability is most appropriately classified within Level 3 of the fair value hierarchy.

The following tables present information about the Company’s financial assets and liabilities that have been measured at fair value as of September 30, 2024 and December 31, 2023 and indicate the fair value hierarchy of the valuation inputs utilized to determine such fair value.

Company Overview

We are an interventional oncology company focused on the treatment of primary cancers metastatic to the liver. Our lead product, the HEPZATO KIT (melphalan for Injection/Hepatic Delivery System), a drug/device combination product, was approved by the US Food and Drug Administration (the “FDA”) on August 14, 2023, indicated as a liver-directed treatment for adult patients with uveal melanoma with unresectable hepatic metastases affecting less than 50% of the liver and no extrahepatic disease, or extrahepatic disease limited to the bone, lymph nodes, subcutaneous tissues, or lung that is amenable to resection, or radiation. The first commercial use of the HEPZATO KIT for the treatment of metastatic hepatic dominant uveal melanoma (“mUM”) took place in January 2024.

In the United States, HEPZATO is considered a combination drug and device product and is regulated as a drug by the FDA. Primary jurisdiction for regulation of HEPZATO has been assigned to the FDA’s Center for Drug Evaluation and Research. The FDA has granted us six orphan drug designations (five for melphalan in the treatment of patients with ocular (uveal) melanoma, cutaneous melanoma, intrahepatic cholangiocarcinoma, hepatocellular carcinoma, and neuroendocrine tumor indications and one for doxorubicin in the treatment of patients with hepatocellular carcinoma).

We have sufficient raw material and component constituent parts of the HEPZATO KIT to meet anticipated demand and we intend to manage supply chain risk through stockpiled inventory and contracting with multiple suppliers for critical components. As of October 31, 2024, 12 facilities have treated at least one patient with the HEPZATO KIT.

In Europe, the hepatic delivery system is a stand-alone medical device having the same device components as HEPZATO, but without the melphalan hydrochloride and is approved for sale under the trade name CHEMOSAT Hepatic Delivery System for Melphalan, or CHEMOSAT, where it has been used at major medical centers to treat a wide range of cancers in the liver. On February 28, 2022, CHEMOSAT received Medical Device Regulation (MDR) certification under the European Medical Devices Regulation (EU)2017/745, which may be considered by jurisdictions when evaluating reimbursement. As of March 1, 2022, we have assumed direct responsibility for sales, marketing and distribution of CHEMOSAT in Europe.

Our clinical development program for HEPZATO was comprised of the FOCUS Clinical Trial for Patients with metastatic hepatic dominant Uveal Melanoma (the “FOCUS Trial”), a global registration clinical trial that investigated objective response rate in patients with mUM. The current focus of our clinical development program is to generate clinical data for CHEMOSAT and HEPZATO in patients with mUM, either as monotherapy or in combination with immunotherapy. On May 6, 2024, we announced the publication of results from our Phase 3 FOCUS Trial, including an Overall Response Rate (“ORR”) of 36.35, which included 7.7% of patients with Complete Response, as determined by an Independent Review Committee. An ORR of 36.3% in the FOCUS study was statistically significantly better than the pooled ORR estimate (a weighted mean of the observed ORR) of 5.5% in the historical control group. We expect that the publication will support increased clinical adoption of and reimbursement for CHEMOSAT in Europe, and support reimbursement in various jurisdictions, including the United States.

In addition to HEPZATO’s use to treat mUM, the Company believes that HEPZATO has the potential to treat other cancers in the liver, such as metastatic colorectal cancer, metastatic neuroendocrine tumors, metastatic breast cancer and intrahepatic cholangiocarcinoma, and plans to begin one or more studies of the HEPZATO KIT to treat such conditions in late 2024 or early 2025. We believe that those and similar disease states are areas of unmet medical needs that represent significant market opportunities.

Revenue

The increase in total revenue for the three and nine months ended September 30, 2024 compared to the same periods in 2023 was due to the commercial launch of the HEPZATO KIT in the U.S. during the first quarter of 2024 and the commercial expansion since such time along with an increase in demand for CHEMOSAT in Europe.

Cost of Goods Sold

The change in cost of goods sold for the three and nine months ended September 30, 2024 compared to the same periods in 2023 is directly related to changes in demand for product revenue.

Research and Development Expenses

Research and development expenses are incurred for the development of HEPZATO and consist primarily of payroll and payments to contract research and development companies. In 2023, these costs primarily related to generating pre-clinical data submission of the NDA and the cost of manufacturing HEPZATO for expanded access program sites utilizing the HEPZATO KIT prior to FDA approval. The decrease for the three and nine months ended September 30, 2024 compared to the same period in 2023 is due to lower costs associated with NDA submission and expanded access program costs offset by an increase in medical affairs and regulatory costs associated with an approved product.

Selling, General and Administrative Expenses

Selling, general and administrative expenses consist primarily of payroll, rent and professional services such as accounting, legal, marketing and commercial preparation services. For the three and nine months ended September 30, 2024 compared to the same periods in 2023, selling, general and administrative expenses increased due to commercial launch activities including marketing-related expenses and additional personnel in the commercial team.

Interest and other Income/Expense

Interest and other income (expense) in 2024 is primarily related to the change in fair value of the Tranche B Warrants liability, interest income associated with marketable securities which is then offset by interest expense related to our debt instruments. There was a decrease in interest expense for the three and nine months ended September 30, 2024 compared to the same periods in 2023 related to the principal loan payments made during 2023 and 2024. A decrease in warrant valuation occurred during the three months ended September 30, 2024 due to the decrease in expected term of the outstanding Tranche B Warrants.

Liquidity and Capital Resources

At September 30, 2024, we had cash and cash equivalents totaling $8.3 million and short-term investments totaling $5.7 million, as compared to cash, cash equivalents and restricted cash totaling $12.7 million and short-term investments totaling $19.8 million at December 31, 2023. During the nine months ended September 30, 2024, we used $17.7 million of cash for operating activities compared to $23.1 million during the nine months ended September 30, 2023, and $8.6 million for principal payments during the nine months ended September 30, 2024, compared to $6.3 million for principal payments during the nine months ended September 30, 2023. At September 30, 2023, we had cash, cash equivalents and restricted cash totaling $40.5 million.

Our future results are subject to substantial risks and uncertainties. We have operated at a loss for our entire history and there can be no assurance that we will ever achieve or maintain profitability. We have historically funded our operations primarily with

Table of Contents

proceeds from sales of common stock, warrants and pre-funded warrants for the purchase of common stock, sales of preferred stock, proceeds from the issuance of convertible debt and borrowings under loan and security agreements.

Funding Requirements

If there is a substantial delay in the activation of additional sites to administer HEPZATO and/or the revenue generated from HEPZATO and CHEMOSAT is less than anticipated, we expect to need to raise additional capital under structures available to us, including debt and/or equity offerings, which may not be on terms favorable to us. In a substantially delayed site activation scenario, we will not have sufficient funds to meet our obligations within twelve months from the issuance date of these condensed consolidated financial statements. As such, there is uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt about our ability to continue as a going concern.

Debt financing and equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise funds through collaborations, or other similar arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs for product candidates and/or grant licenses on terms that may not be favorable to us, any of which may reduce the value of our common stock. If we are unable to raise additional funds through equity or debt financings when needed, we may be required to delay, limit, reduce or terminate our product development or future commercialization efforts or grant rights to develop and market our product candidates to third parties even if we would otherwise prefer to develop and market such product candidates ourselves.

We also expect to use cash and cash equivalents to fund activities relating to commercial support for HEPZATO, CHEMOSAT and any future clinical research trials and operating activities. Our future liquidity and capital requirements will depend on numerous factors, including our ability to successfully commercialize HEPZATO and CHEMOSAT; the cost of and our ability to obtain additional regulatory approvals for HEPZATO and CHEMOSAT in additional jurisdictions and for additional indications; our ability to build a commercial infrastructure for HEPZATO for the treatment of mUM in the United States; obtaining regulatory approvals and complying with applicable laws and regulations; the timing and effectiveness of product commercialization activities, including marketing arrangements; our headcount growth and associated costs as we expand our research and development and establish a commercial infrastructure; the timing and costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights; the resolution of any disputes with third parties; and the effect of competing technological and market developments.

Capital Commitments

Our capital commitments over the next twelve months include (a) $6.8 million to satisfy accounts payable, accrued expenses, current lease liabilities and current medac settlement and (b) $2.0 million of convertible note principal payments, if the holders do not elect to convert the notes into equity. Additional capital commitments beyond the next twelve months include (a) $1.3 million of lease liabilities and (b) $0.6 million for settlement of litigation with medac.

June 2024 Shelf Registration Statement

On June 28, 2024, we filed a universal shelf registration statement on Form S-3 (the “June 2024 Shelf Registration Statement”) with the SEC, pursuant to which we may offer, issue and sell any combination of shares of our common stock, par value $0.01 per share, shares of our preferred stock, par value $0.01 per share, debt securities, warrants to purchase common stock, preferred stock and/or debt securities, in one or more series, and units consisting of any combination of the other types of securities registered under such June 2024 Shelf Registration Statement in an aggregate amount of up to $150 million, in each case, to the public in one or more registered offerings.

At-the-Market Offering

We previously entered into a Controlled Equity OfferingSM Sales Agreement (“ATM Sales Agreement”), with Cantor Fitzgerald & Co. (the “Sales Agent”), pursuant to which we may offer and sell, at our sole discretion through the Sales Agent, shares of our common stock from time to time. Pursuant to a prospectus supplement (the “ATM Prospectus Supplement”), filed with the SEC on February 27, 2023, we could sell shares of common stock under the ATM Sales Agreement up to an aggregate of $17.0 million. To date, we have sold approximately $4.0 million of our common stock, prior to issuance costs, under the ATM Sales Agreement. No sales were made during the three and nine months ended September 30, 2024.

The registration statement the ATM Prospectus Supplement was a part of, expired on July 1, 2024 and we can no longer make sales under the ATM Prospectus Supplement.

Avenue Loan Agreement

On August 6, 2021, we entered into the Avenue Loan Agreement with Avenue Venture Opportunities Fund, L.P. (the “Lender,” or “Avenue”), as amended on March 31, 2023, for a term loan in an aggregate principal amount of up to $20 million (the “Avenue Loan”). The Avenue Loan bore interest at an annual rate equal to the greater of (a) the sum of 7.7% plus the prime rate as reported in The Wall Street Journal and (b) 10.95%. The interest rate at September 30, 2024 was 16.20%. The Avenue Loan was secured by all of our assets globally, including intellectual property. On March 15, 2023, we returned to Avenue $4.0 million held in the restricted cash to pay down a portion of the outstanding loan balance, principal payments of $2.1 million and an incremental 4.25% of the final payment of $0.2 million. On March 31, 2023, we reached an agreement to amend the existing loan agreement with Avenue to defer the interest only period to September 30, 2023, with an additional extension option upon the FDA approval for the HEPZATO KIT and subsequent receipt of at least $10 million from the sale and issuance of equity securities. In exchange for this extension, we agreed to provide Avenue with 34,072 warrants to purchase shares of common stock at an exercise price of $0.01 per warrant share, all of which were exercised in April 2024. On August 14, 2023, we received the FDA approval for the HEPZATO KIT and subsequently received over $10 million from the exercise of warrants. At our option, we elected to extend the interest only period to December 31, 2023. Principal payments of approximately $1.0 million began in January 2024.

Avenue did not exercise its option to convert the remaining principal amount of the Avenue Loan into shares of our common stock and on August 1, 2024, upon maturity of the Avenue loan, we made the final payment due there under. Avenue has released us from all obligations and returned all security interests back to us.

Series E and Series E-1 Warrants

In June and July 2019, we entered into definitive securities purchase agreements with certain investors pursuant to which we issued shares of common stock and Series E and Series E-1 Warrants to purchase shares of common stock. The Series E and Series E-1 Warrants have an exercise price of $10.00 per share and expire on December 24, 2024. No Series E and Series E-1 Warrants were exercised during the three and nine months ended September 30, 2024. As of September 30, 2024, 1,758,843 of such warrants remain outstanding.

Series F Warrants

In May 2020, we completed an underwritten public offering consisting of shares of common stock, Series F warrants to purchase shares of common stock and, to certain investors, in lieu of shares of common stock, pre-funded warrants to purchase shares of common stock. The Series F Warrants have an exercise price of $10.00 per share of common stock and expire on May 5, 2025, while the pre-funded warrants issued in such offering have an exercise price of $0.01, if exercised via cash payment. No Series F Warrants were exercised during the three and nine months ended September 30, 2024. As of September 30, 2024, 1,851,900 of the Series F Warrants remain outstanding.

March 2023 Private Placement

On March 27, 2023, we entered into a securities purchase agreement with certain accredited investors (the “Preferred Purchase Agreement”), pursuant to which we agreed to issue and sell, in a private placement (the “Series F Preferred Offering”), (i) 24,900 shares of our Series F-1 Convertible Preferred Stock, par value $0.01 per share (the “Series F-1 Preferred Stock”), (ii) tranche A warrants (the “Preferred Tranche A Warrant”) to acquire 34,859 shares of Series F-3 Convertible Preferred Stock, par value $0.01 per share (the “Series F-3 Preferred Stock”) and (iii) tranche B warrants (the “Preferred Tranche B Warrant,” together with the Preferred Tranche A Warrant, the “Preferred Warrants”) to acquire 24,900 shares of Series F-4 Convertible Preferred Stock, par value $0.01 per share (the “Series F-4 Preferred Stock”) for an aggregate offering price of $24.9 million before deducting the fees paid to the placement agent and the financial advisors and other financing expenses payable by us.

Also on March 27, 2023, we entered into a securities purchase agreement with the our Chief Executive Officer, Gerard Michel, pursuant to which we agreed to issue and sell, in a private placement (the “Common Offering”, and together with the Series F Preferred Offering, the “Private Placements”), (i) 19,646 shares of common stock, (ii) tranche A warrants to acquire 31,110 shares of common stock (the “Common Tranche A Warrants”, and together with the Preferred Tranche A Warrants, the “Tranche A Warrants”) and (iii) tranche B warrants to acquire 16,666 shares of common stock (the “Common Tranche B Warrants”, and together with the Preferred Tranche B Warrants, the “Tranche B Warrants”) for an approximate aggregate offering price of $0.1 million.

On June 12, 2023, the stockholders approved the Private Placements at the annual general meeting of stockholders and therefore, the Preferred Warrants and Common Warrants issued in the Private Placements became exercisable. The exercise of all such Preferred Warrants and Common Warrants would generate approximately $60.0 million in proceeds to us. As of September 30, 2024, all of the Preferred Tranche A Warrants were exercised for an aggregate exercise price of $34.9 million into 34,859 shares of Series F-3 Preferred Stock, which were subsequently converted into shares of common stock in accordance with the terms of

Table of Contents

the Certificate of Designation and Rights relating to the Series F Preferred Offering, 250 shares Preferred Tranche B Warrants were exercised for an aggregate exercise price of $0.3 million into 250 shares of Series F-3 Preferred Stock, which were subsequently converted into shares of common stock in accordance with the terms of the Certificate of Designation and Rights relating to the Series F Preferred Offering, and all of the Common Tranche A Warrants were exercised for an aggregate exercise price of $0.1 million into 31,110 shares of common stock.

During the quarter ending September 30, 2024, we recorded at least $10.0 million in quarterly U.S. revenue due to the commercialization of the HEPZATO KIT which was announced by us on October 17, 2024, triggering the 21 day exercise period. As of November 5, 2024, 24,900 Preferred Tranche B Warrants and 16,666 Common Tranche B Warrants were exercised by the November 6, 2024 expiration date which resulted in $25 million of cash proceeds to us.

As of September 30, 2024, 58,924 shares of our Series F-1, F-2, F-3 and F-4 Preferred Stock were converted into 15,005,211 shares of common stock.

March 2024 Private Placement

On March 14, 2024, we and certain accredited investors (each an “Investor” and collectively, the “Investors”) entered into a securities purchase agreement (the “Securities Purchase Agreement”) pursuant to which we agreed to sell and issue to the Investors in a private placement (the “Private Placement”) (i) an aggregate of 876,627 shares of the Company’s common stock, par value $0.01 per share, at a purchase price of $3.72 per share, and (ii) to certain investors, in lieu of shares of common stock, 1,008,102 pre-funded warrants (the “Pre-Funded Warrants”) at a price per Pre-Funded Warrant of $3.71 (the “Warrant Shares” and together with the Shares, the “Securities”) with an exercise price of $0.01. As of September 30, 2024 the Pre-Funded Warrants have been exercised in full.

The Private Placement closed on March 19, 2024. We received gross proceeds of approximately $7.0 million, before deducting offering expenses payable by us.

CBIZ Acquisition of Marcum LLP

On November 1, 2024, CBIZ, Inc. acquired substantially all of the non-attest assets of Marcum LLP. In a separate transaction, CBIZ CPAs P.C., a national independent certified public accounting firm with which CBIZ Inc. has an existing Administrative Services Agreement, purchased from Marcum LLP substantially all of Marcum’s attest business assets. On August 2, 2024, Marcum LLP informed the Company that it would not be independent with respect to the completion of the fiscal year ended December 31, 2024, audit of the consolidated financial statements as a result of certain non-attest services that were performed by CBIZ, Inc. (stock warrants valuation) during the period under audit for the Company. For the following reasons, the Audit Committee of the Board of Directors of the Company and Marcum have each concluded, and are of the view that a reasonable investor with knowledge of all relevant facts and circumstances would conclude, that the provision of these services did not

Table of Contents

impair Marcum LLP’s objectivity and impartiality with respect to Marcum LLP’s audit of the Company’s consolidated financial statements:

1.All of the valuation work performed by CBIZ, Inc. was prior to July 31, 2024, when the proposed transaction between CBIZ, Inc. and Marcum LLP was announced. The audit engagement team was not aware of this proposed transaction prior to July 31st. The Marcum audit partner became aware on July 30th evening from a Partner meeting which was convened by the Marcum CEO.

2.CBIZ, Inc. services did not involve decision making and supervisory responsibilities over and on behalf of the Company management.

3.The Company terminated CBIZ, Inc.’s engagement soon after being notified of this conflict and hired an unrelated third party to perform the September 30, 2024, valuation and to independently reperform the June 30, 2024, valuation. The unrelated third party developed the fair value estimates independent from CBIZ, Inc. and developed its methodology from inputs and assumptions provided by the Company and in consultation with the Company management.

4.No personnel from CBIZ, Inc. who worked on the Company’s engagement will be part of the audit team or have any involvement in the audit.

5.The fee earned by CBIZ, Inc. for the non-attest services is insignificant to CBIZ, Inc., and the Company.
