FOSTER CITY, Calif. & MORRIS PLAINS, N.J.--(BUSINESS WIRE)-- Gilead Sciences, Inc. (Nasdaq: GILD) and Immunomedics (Nasdaq: IMMU) announced today that the companies have entered into a definitive agreement pursuant to which Gilead will acquire Immunomedics for $88.00 per share in cash. The transaction, which values Immunomedics at approximately $21 billion, was unanimously approved by both the Gilead and Immunomedics Boards of Directors and is anticipated to close during the fourth quarter of 2020.

The agreement will provide Gilead with Trodelvy^TM(sacituzumab govitecan-hziy), a first-in-class Trop-2 directed antibody-drug conjugate (ADC) that was granted accelerated approval by the U.S. Food and Drug Administration (FDA) in April for the treatment of adult patients with metastatic triple-negative breast cancer (mTNBC) who have received at least two prior therapies for metastatic disease. Immunomedics plans to submit a supplemental Biologics License Application (BLA) to support full approval of Trodelvy in the United States in the fourth quarter of 2020. Immunomedics is also on track to file for regulatory approval in Europe in the first half of 2021.

In the Phase 3 ASCENT study, which was halted early due to efficacy based on the unanimous recommendation of the independent Data Safety Monitoring Committee, Trodelvy significantly improved progression-free survival (PFS) and overall survival (OS) in previously treated patients with advanced mTNBC. Detailed results from this study are expected to be presented at the upcoming European Society for Medical Oncology (ESMO) Virtual Congress 2020.

Beyond mTNBC, Trodelvy is also being studied in an ongoing Phase 3 trial in third line HR+/HER2- breast cancer and a registrational Phase 2 study in bladder cancer. Additional ongoing studies are evaluating the potential of Trodelvy as a treatment for non-small cell lung cancer and other solid tumor types. Trodelvy is being studied as both a monotherapy and in combination with checkpoint inhibitors and other non-immuno-oncology products by Immunomedics and independent investigators. Additional clinical data for Trodelvy in bladder cancer and other solid tumors will also be presented at ESMO this coming week.

“This acquisition represents significant progress in Gilead’s work to build a strong and diverse oncology portfolio. Trodelvy is an approved, transformational medicine for a form of cancer that is particularly challenging to treat. We will now continue to explore its potential to treat many other types of cancer, both as a monotherapy and in combination with other treatments,” said Daniel O’Day, Chairman and Chief Executive Officer, Gilead Sciences. “We look forward to welcoming the talented Immunomedics team to Gilead so we can continue to advance this important new medicine for the benefit of patients with cancer worldwide.”

“We are very pleased that Gilead recognized the value of Trodelvy – both for the important role it has already begun to play for patients with metastatic triple-negative breast cancer and for its potential to help many other patients with cancer in the future,” said Behzad Aghazadeh, PhD, Executive Chairman of Immunomedics. “We are excited for the opportunities ahead of us as we join with Gilead to advance our shared mission in defeating cancer. By working with Gilead, we have the opportunity to accelerate our progress and improve care for patients in need of new therapies.”

Compelling Strategic Benefits

Rapidly Expanding Trodelvy’s Benefit for Patients Globally: After closing Gilead intends to initiate numerous additional mid- and late-stage studies in the near term to determine which patients will benefit from Trodelvy as both a monotherapy or in combination with other products. Gilead brings commercial, medical, regulatory and manufacturing expertise, which will help rapidly advance Trodelvy through development and reach additional patients. Gilead will also bring to Immunomedics an established infrastructure and operations in Europe and Japan to support the launch of Trodelvy in those regions, pending approval. After closing, Gilead will retain global rights to Trodelvy outside of greater China, South Korea and certain Southeast Asian countries.

Trodelvy is Foundational to Gilead’s Oncology Franchise: Trodelvy will bring to Gilead a cornerstone product that broadens and deepens the company’s solid tumor pipeline, building on current marketed products and late-stage clinical candidates for patients with hematological malignancies at Kite and Gilead, including Yescarta^®, Tecartus^® and magrolimab. Trodelvy is approved as a third-line treatment for mTNBC and has shown promise for earlier stages of the disease. TNBC represents approximately 15 to 20 percent of all breast cancer cases and is generally considered the most aggressive form of breast cancer. HR+/HER2- breast cancer accounts for more than 70 percent of all breast cancers.

Accelerates Gilead’s Revenue and EPS Growth: Trodelvy was launched in May of 2020 and has significant commercial potential in mTNBC and other solid tumors. In addition to immediately accelerating Gilead’s revenue growth, the acquisition of Immunomedics is expected to be neutral to accretive to Gilead’s non-GAAP EPS in 2023 and significantly accretive thereafter.

Transaction Terms and Financing

Under the terms of the merger agreement, a wholly-owned subsidiary of Gilead will promptly commence a tender offer to acquire all of the outstanding shares of Immunomedics’ common stock. The $88.00 per share acquisition price represents a 108 percent premium to Immunomedics’ closing price on September 11, 2020. Following successful completion of the tender offer, Gilead will acquire all remaining shares not tendered in the offer through a second step merger at the same price as the tender offer.

The consummation of the tender offer is subject to various conditions, including a minimum tender of at least a majority of outstanding Immunomedics shares, the expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act and other customary conditions.

The tender offer is not subject to a financing condition and will be funded through approximately $15 billion in cash on hand, as well as approximately $6 billion in newly issued debt. Gilead expects to retain an investment grade credit rating following this transaction and this agreement does not alter Gilead’s stated capital allocation strategy or its commitment to maintain and grow its dividend over time.
