Exhibit 99.1

Subject: A message from Novartis regarding the recently announced transaction between MorphoSys and Novartis

Dear MorphoSys team,

Following yesterday’s announcement, we are reaching out to express our excitement to build on our long-standing development partnership.

You have built a world-class company whose purpose is rooted in aspiring to redefine how cancer is treated. At Novartis, our mission is to reimagine medicine to improve and extend people’s lives. We firmly believe that our companies strategically and culturally are aligned. We are especially excited by MorphoSys’ progress, hard work and dedication in advancing its early and late-stage oncology pipeline, including pelabresib, a potential next-generation treatment for myelofibrosis.

We appreciate your patience and understanding as we work to finalize the transaction. We want to assure you that we recognize the importance of clear, timely and open communication and emphasize that our priority is to minimize disruption and to ensure successful business continuity. At the same time, until formal completion of the transaction, we know we must continue to operate as separate and independent companies.

After the closing, we look forward to learning from you, supporting you and working together on our joint purpose to improve people’s lives and reach more patients.

We express our sincere gratitude for all your commitment and resilience in the meantime.

Best regards,

Shreeram Aradhye, M.D.	Patrick Horber, M.D.	Victor Bulto

Important Information about the Tender Offer

This communication is neither an offer to sell or purchase nor a solicitation of an offer to sell or purchase MorphoSys shares. Moreover, this announcement is neither an offer to purchase nor a solicitation to purchase shares of Novartis data42 AG. The final terms and further provisions regarding the takeover offer (also referred to a tender offer) will be in the offer document once its publication has been approved by the German Federal Financial Supervisory Authority (Bundesanstalt für Finanzdienstleistungsaufsicat or “BaFin”). Novartis data42 AG reserves the right to deviate from the basic terms presented herein in the final terms and provisions. Investors and holders of MorphoSys shares are strongly recommended to read the offer document and all other documents in connection with the public takeover offer as soon as they are published, as they will contain important information.

Subject to the exceptions described in the offer document and any exceptions granted by the relevant regulatory authorities, a public takeover offer is not being made, directly or indirectly, in or into those jurisdictions where to do so would constitute a violation pursuant to the laws of such jurisdiction.

The tender offer described in this communication has not yet commenced, and this communication is neither an offer to purchase nor a solicitation of an offer to sell securities. The terms and conditions of the tender offer will be published in, and the offer to purchase ordinary shares of MorphoSys will be made only pursuant to, the offer document and related offer materials prepared by Novartis AG and Novartis data42 AG and as approved by BaFin. Once the necessary permission from BaFin has been obtained, the offer document and related offer materials will be published in Germany and also filed with the SEC on Schedule TO at the time the tender offer is commenced. MorphoSys intends to file a solicitation/recommendation statement on Schedule 14D-9 with the SEC with respect to the tender offer and to publish a recommendation statement pursuant to Sec. 27 of the German Securities Acquisition and Takeover Act.

In order to reconcile certain areas where German law and U.S. law conflict, Novartis AG and Novartis data42 AG expect to request no-action and exemptive relief from the SEC to conduct the tender in the manner described in the offer document.

Novartis AG and its affiliates or brokers (acting as agents of Novartis data42 AG or its affiliates, if any) may, to the extent permitted by applicable laws or regulations, directly or indirectly, acquire shares in MorphoSys or enter into agreements to acquire shares outside of the tender offer before, during or after the term of the tender offer. This also applies to other securities convertible into, exchangeable for or exercisable for shares of MorphoSys. These purchases may be concluded via the stock exchange at market prices or outside the stock exchange on negotiated terms. If such purchases or agreements to purchase are made, they will be made outside the United States and will comply with applicable law, including, to the extent applicable, the Securities Exchange Act of 1934, as amended, and the rules and regulations thereunder (including pursuant to any requested no-action and exemptive relief from the SEC).

All information regarding such purchases will be disclosed in accordance with the laws or regulations applicable in Germany or any other relevant jurisdiction. In addition, the financial advisors of Novartis AG may also act in the ordinary course of trading in securities of MorphoSys, which may include purchases or agreements to purchase such securities.

INVESTORS AND SECURITY HOLDERS ARE STRONGLY ADVISED TO READ THE TENDER OFFER STATEMENT, INCLUDING AN OFFER TO PURCHASE, MEANS TO TENDER AND RELATED TENDER OFFER DOCUMENTS THAT WILL BE FILED BY NOVARTIS AG AND NOVARTIS DATA42 AG WITH THE SEC AND THE RELATED SOLICITATION/RECOMMENDATION STATEMENT ON SCHEDULE 14D-9 THAT WILL BE FILED BY MORPHOSYS WITH THE SEC, WHEN THEY BECOME AVAILABLE, BECAUSE THEY WILL CONTAIN IMPORTANT INFORMATION.
