Recent Business Highlights

During and since the fourth quarter, Delcath:

• Achieved medical device regulation certification for CHEMOSAT^® in Europe

• Appointed David Hoffman as General Counsel and Chief Compliance Officer and Anthony Dias as Vice President of Finance

In addition, during and since the fourth quarter, independent investigators published:

• Repeated percutaneous hepatic perfusion with melphalan can maintain long-term response in patients with liver cancers in the journal Cardiovascular and Interventional Radiology¹

• Chemosaturation with percutaneous hepatic perfusion of melphalan for metastatic uveal melanoma in the journal Melanoma Research²
