MorphoSys to Present Data on Tafasitamab (Monjuvi®) at the

2021 ASCO Annual Meeting

PLANEGG/MUNICH, Germany - May 19, 2021 - MorphoSys AG (FSE:MOR; NASDAQ:MOR) today announced that new data from the tafasitamab (Monjuvi®) development program will be presented at the upcoming 2021 American Society of Clinical Oncology (ASCO) Annual Meeting from June 4-8, 2021.

Tafasitamab is a humanized Fc-modified cytolytic CD19 targeting monoclonal antibody, which was approved as Monjuvi® (tafasitamab-cxix) in July 2020 by the U.S. Food and Drug Administration in combination with lenalidomide for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified, including DLBCL arising from low grade lymphoma, and who are not eligible for autologous stem cell transplant (ASCT). This indication is approved under accelerated approval based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

"We are proud to present important findings from our comprehensive development program for tafasitamab at the ASCO Annual Meeting, including three-yearfollow-up data from the Phase 2 L-MIND study showing a long durability of responses and overall survival in patients with R/R DLBCL," commented Dr. Malte Peters, Chief Research and Development Officer at MorphoSys. "In addition, we will show details from our First-MIND study in front-line DLBCL, indicating our ambition to position Monjuvi as a back-bone strategy in DLBCL and to increase cure rates or duration of remission in DLBCL across all lines of therapy."

Abstracts accepted for presentation at the ASCO Annual Meeting include:

About Tafasitamab

Tafasitamab is a humanized Fc-modified cytolytic CD19 targeting monoclonal antibody. In 2010, MorphoSys licensed exclusive worldwide rights to develop and commercialize tafasitamab from Xencor, Inc. Tafasitamab incorporates an XmAb® engineered Fc domain, which mediates B-cell lysis through apoptosis and immune effector mechanism including antibody-dependentcell-mediated cytotoxicity (ADCC) and antibody-dependent cellular phagocytosis (ADCP).

Monjuvi® (tafasitamab-cxix) is approved by the U.S. Food and Drug Administration in combination with lenalidomide for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) not otherwise specified, including DLBCL arising from low grade lymphoma, and who are not eligible for autologous stem cell transplant (ASCT). This indication is approved under accelerated approval based on overall response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial(s).

In January 2020, MorphoSys and Incyte entered into a collaboration and licensing agreement to further develop and commercialize tafasitamab globally. Monjuvi® is being co-commercialized by Incyte and MorphoSys in the United States. Incyte has exclusive commercialization rights outside the United States.

A marketing authorization application (MAA) seeking the approval of tafasitamab in combination with lenalidomide in the EU has been validated by the European Medicines Agency (EMA) and is currently under review for the treatment of adult patients with relapsed or refractory DLBCL, including DLBCL arising from low grade lymphoma, who are not candidates for ASCT.

Tafasitamab is being clinically investigated as a therapeutic option in B-cell malignancies in a number of ongoing combination trials.

Your healthcare provider will monitor your blood counts during treatment with MONJUVI. Tell your healthcare provider right away if you get a fever of 100.4°F (38°C) or above, or any bruising or bleeding.
• Infections. Serious infections, including infections that can cause death, have happened in people during treatments with MONJUVI and after the last dose. Tell your healthcare provider right away if you get a fever of 100.4°F (38°C) or above, or develop any signs and symptoms of an infection.

The most common side effects of MONJUVI include:

Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

Before you receive MONJUVI, tell your healthcare provider about all your medical conditions, including if you:

• Have an active infection or have had one recently.
• Are pregnant or plan to become pregnant. MONJUVI may harm your unborn baby. You should not become pregnant during treatment with MONJUVI. Do not receive treatment with MONJUVI in combination with lenalidomide if you are pregnant because lenalidomide can cause birth defects and death of your unborn baby.
  o You should use an effective method of birth control (contraception) during treatment and for at least 3 months after your final dose of MONJUVI.
  o Tell your healthcare provider right away if you become pregnant or think that you may be pregnant during treatment with MONJUVI.
