Exhibit 99.1

Lilly Announces Agreement To Acquire Loxo Oncology

INDIANAPOLIS, IN and STAMFORD, CT – Eli Lilly and Company (NYSE: LLY) and Loxo Oncology, Inc. (NASDAQ: LOXO) today announced a definitive agreement for Lilly to acquire Loxo Oncology for $235.00 per share in cash, or approximately $8.0 billion. Loxo Oncology is a biopharmaceutical company focused on the development and commercialization of highly selective medicines for patients with genomically defined cancers.

The acquisition would be the largest and latest in a series of transactions Lilly has conducted to broaden its cancer treatment efforts with externally sourced opportunities for first-in-class and best-in-class therapies. Loxo Oncology is developing a pipeline of targeted medicines focused on cancers that are uniquely dependent on single gene abnormalities that can be detected by genomic testing. For patients with cancers that harbor these genomic alterations, a targeted medicine could have the potential to treat the cancer with dramatic effect.

Loxo Oncology has a promising portfolio of approved and investigational medicines, including:

“Using tailored medicines to target key tumor dependencies offers an increasingly robust approach to cancer treatment,” said Daniel Skovronsky, M.D., Ph.D., Lilly’s chief scientific officer and president of Lilly Research Laboratories. “Loxo Oncology’s portfolio of RET, BTK and TRK inhibitors targeted specifically to patients with mutations or fusions in these genes, in combination with advanced diagnostics that allow us to know exactly which patients may benefit, creates new opportunities to improve the lives of people with advanced cancer.”

“We are gratified that Lilly has recognized our contributions to the field of precision medicine and are excited to see our pipeline benefit from the resources and global reach of the Lilly organization,” said Josh Bilenker, M.D., chief executive officer of Loxo Oncology. “Tumor genomic profiling is becoming standard-of-care, and it will be critical to continue innovating against new targets, while anticipating mechanisms of resistance to available therapies, so that patients with advanced cancer have the chance to live longer and better lives.”

“Lilly Oncology is committed to developing innovative, breakthrough medicines that will make a meaningful difference for people with cancer and help them live longer, healthier lives,” said Anne White, president of Lilly Oncology. “The acquisition of Loxo Oncology represents an exciting and

immediate opportunity to expand the breadth of our portfolio into precision medicines and target cancers that are caused by specific gene abnormalities. The ability to target tumor dependencies in these populations is a key part of our Lilly Oncology strategy. We look forward to continuing to advance the pioneering scientific innovation begun by Loxo Oncology.”

“We are excited to have reached this agreement with a team that shares our commitment to ensuring that emerging translational science reaches patients in need,” said Jacob Van Naarden, chief operating officer of Loxo Oncology. “We are confident that the work we have started, which includes an FDA approved drug, and a pipeline spanning from Phase 2 to discovery, will continue to thrive in Lilly’s hands.”

Under the terms of the agreement, Lilly will commence a tender offer to acquire all outstanding shares of Loxo Oncology for a purchase price of $235.00 per share in cash, or approximately $8.0 billion. The transaction is not subject to any financing condition and is expected to close by the end of the first quarter of 2019, subject to customary closing conditions, including receipt of required regulatory approvals and the tender of a majority of the outstanding shares of Loxo Oncology’s common stock. Following the successful closing of the tender offer, Lilly will acquire any shares of Loxo Oncology that are not tendered into the tender offer through a second-step merger at the tender offer price.

The tender offer represents a premium of approximately 68 percent to Loxo Oncology’s closing stock price on January 4, 2019, the last trading day before the announcement of the transaction. Loxo Oncology’s board recommends that Loxo Oncology’s shareholders tender their shares in the tender offer. Additionally, a Loxo Oncology shareholder, beneficially owning approximately 6.6 percent of Loxo Oncology’s outstanding common stock, has agreed to tender its shares in the tender offer.

This transaction will be reflected in Lilly’s financial results and financial guidance according to Generally Accepted Accounting Principles (GAAP). Lilly will provide an update to its 2019 financial guidance, including the expected impact from the acquisition of Loxo Oncology, as part of its fourth-quarter and full-year 2018 financial results announcement on February 13, 2019.

For Lilly, Deutsche Bank is acting as the exclusive financial advisor and Weil, Gotshal & Manges LLP is acting as legal advisor in this transaction. For Loxo Oncology, Goldman Sachs & Co. LLC is acting as exclusive financial advisor and Fenwick & West LLP is acting as legal advisor.

Conference Call and Webcast

Lilly will conduct a conference call with the investment community and media today at 8:45 a.m. EST to discuss the acquisition of Loxo Oncology. Investors, media and the general public can access a live webcast of the conference call through the Webcasts & Presentations link that will be posted on Lilly’s website at www.lilly.com. The webcast of the conference call will be available for replay through February 7, 2019.

About LOXO-292

LOXO-292 is an oral and selective investigational new drug in clinical development for the treatment of patients with cancers that harbor abnormalities in the rearranged during transfection (RET) kinase. RET fusions and mutations occur across multiple tumor types with varying frequency. LOXO-292 was designed to inhibit native RET signaling as well as anticipated acquired resistance mechanisms that could otherwise limit the activity of this therapeutic approach. LOXO-292 has been granted Breakthrough Therapy Designation by the U.S. FDA for three indications, and could launch as early as 2020.

About LOXO-305

LOXO-305 is an investigational, highly selective non-covalent Bruton’s tyrosine kinase (BTK) inhibitor. BTK plays a key role in the B-cell antigen receptor signaling pathway, which is required for the development, activation and survival of normal white blood cells, known as B-cells, and malignant B-cells. BTK is a validated molecular target found across numerous B-cell leukemias and lymphomas including chronic lymphocytic leukemia, Waldenstrom’s macroglobulinemia, mantle cell lymphoma and marginal zone lymphoma.

About Vitrakvi^® (larotrectinib)

Vitrakvi is an oral TRK inhibitor for the treatment of adult and pediatric patients with solid tumors with a neurotrophic receptor tyrosine kinase (NTRK) gene fusion without a known acquired resistance mutation that are either metastatic or where surgical resection will likely result in severe morbidity, and have no satisfactory alternative treatments or have progressed following treatment. This indication is approved under accelerated approval based on overall response rate and duration of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trials.

About LOXO-195

LOXO-195 is a selective TRK inhibitor that is being investigated to address potential mechanisms of acquired resistance that may emerge in patients receiving Vitrakvi^® (larotrectinib) or other multikinase inhibitors with anti-TRK activity.
