• Received FDA Clearance of an IND Application for a Phase 2 Clinical Trial of HEPZATO™ in Liver-Dominant Metastatic Colorectal Cancer

• The National Comprehensive Cancer Network (NCCN) updated its Clinical Practice Guidelines in Oncology (NCCN Guidelines®) for metastatic uveal melanoma (mUM) treatment to include HEPZATO KIT as an option for patients with hepatic-dominant uveal melanoma, expanding from the previous guidance that limited its use to those with liver-confined metastases

"In 2024, the successful launch of HEPZATO drove strong financial and operational results, including positive adjusted EBITDA in the fourth quarter," said Gerard Michel, Delcath's Chief Executive Officer. "As HEPZATO becomes more established as a leading treatment option for metastatic uveal melanoma, we're seeing growing adoption across treatment centers and meaningful revenue growth. This momentum enables us to advance R&D programs targeting other liver-dominant cancers, including metastatic colorectal and breast cancer."

Fourth Quarter and Full Year 2024 Results

Total revenue for the quarter ended December 31, 2024 was $15.1 million compared to $0.5 million for the same period in the prior year. Revenue in the quarter includes sales of $13.7 million of HEPZATO in the U.S. and $1.4 million of CHEMOSAT in Europe.

Total revenue for the year-ended December 31, 2024 was $37.2 million compared to $2.1 million for the same period in the prior year. Revenue in 2024 includes sales of $32.3 million of HEPZATO in the U.S. and $4.9 million of CHEMOSAT in Europe.

Research and development expenses for the quarter and year-ended December 31, 2024, were $2.9 million and $13.9 million, respectively compared to $4.7 million and $17.5 million for the same periods in the prior year. The decrease is primarily due to lower costs associated with the 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 for the quarter and year-ended December 31, 2024, were $7.0 million and $29.6 million, respectively compared to $7.0 million and $22.1 million for the same periods in the prior year. The increase is primarily due to commercial launch activities including marketing-related expenses and additional personnel in the commercial team.

Net loss for the quarter and year-ended December 31, 2024 was $3.4 million and $26.4 million, respectively compared to net loss of $11.1 million and $47.7 million for the same periods in the prior year.

Non-GAAP adjusted EBITDA for the quarter and year-ended December 31, 2024 was $4.6 million and loss of $2.5 million, respectively, compared to adjusted EBITDA loss of $9.3 million and $30.0 million for the same periods in the prior year.

GAAP v. Non-GAAP Measures

Delcath's reported earnings are prepared in accordance with generally accepted accounting principles in the United States, or GAAP, and represent earnings as reported to the Securities and Exchange Commission. Delcath has provided in this release certain financial information that has not been prepared in accordance with GAAP. Delcath's management believes that the non-GAAP adjusted EBITDA described in this release, which includes adjustments for specific items that are generally not indicative of our core operations, provides additional information that is useful to investors in understanding Delcath's underlying performance, business and performance trends, and helps facilitate period-to-period comparisons and comparisons of its financial measures with other companies in Delcath's industry. However, the non-GAAP financial measures that Delcath uses may differ from measures that other companies may use. Non-GAAP financial measures are not required to be uniformly applied, are not audited and should not be considered in isolation or as substitutes for results prepared in accordance with GAAP.

About Delcath Systems, Inc., HEPZATO KIT and CHEMOSAT

Delcath Systems, Inc. is an interventional oncology company focused on the treatment of primary and metastatic liver cancers. The company's proprietary products, HEPZATO KIT™ (HEPZATO (melphalan) for Injection/Hepatic Delivery System) and CHEMOSAT^® Hepatic Delivery System for Melphalan percutaneous hepatic perfusion (PHP), are designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated side effects during a PHP procedure.

In the United States, HEPZATO KIT is considered a combination drug and device product and is regulated and approved for sale as a drug by the FDA. HEPZATO KIT is comprised of the chemotherapeutic drug melphalan and Delcath's proprietary Hepatic Delivery System (HDS). The HDS is used to isolate the hepatic venous blood from the systemic circulation while simultaneously filtrating hepatic venous blood during melphalan infusion and washout. The use of the HDS results in loco-regional delivery of a relatively high melphalan dose, which can potentially induce a clinically meaningful tumor response with minimal hepatotoxicity and reduce systemic exposure. HEPZATO KIT is approved in the United States as a liver-directed treatment for adult patients with metastatic uveal melanoma (mUM) 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. Please see the full Prescribing Information, including BOXED WARNING for the HEPZATO KIT.

In Europe, the device-only configuration of the HDS is regulated as a Class III medical device and is approved for sale under the trade name CHEMOSAT Hepatic Delivery System for Melphalan, or CHEMOSAT, where it has been used in the conduct of percutaneous hepatic perfusion procedures at major medical centers to treat a wide range of cancers of the liver.
