Nuvation Bio to Acquire AnHeart Therapeutics in All-Stock Transaction

Acquisition transforms Nuvation Bio into late-stage global oncology company with potential to become a commercial organization by the end of 2025

Acquisition adds taletrectinib, a next-generation, potentially best-in-class ROS1 inhibitor with Breakthrough Therapy Designations currently completing two pivotal studies for the treatment of patients with ROS1-positive non-small cell lung cancer (NSCLC)

Acquisition also adds safusidenib, a potentially best-in-class mutant IDH1 inhibitor currently being evaluated in a global Phase 2 study of patients with grades 2 and 3 IDH1-mutant glioma

All-stock transaction preserves Nuvation Bio's robust cash balance and enables development of both new assets and current pipeline without a need to raise capital in the near term

Nuvation Bio Inc. (NYSE:NUVB), a biopharmaceutical company tackling some of the greatest unmet needs in oncology by developing differentiated and novel therapeutic candidates, and AnHeart Therapeutics Ltd. (AnHeart), a global clinical-stage biopharmaceutical company developing novel precision therapies for people with cancer, today announced that the companies have entered into a definitive agreement for Nuvation Bio to acquire AnHeart in an all-stock transaction (the Acquisition). Immediately following the closing of the Acquisition, the former shareholders of AnHeart will own approximately 33% and the current stockholders of Nuvation Bio will own approximately 67% of Nuvation Bio on a fully diluted basis. The Acquisition, which has been approved by the board of directors of each company and is subject to approval by AnHeart's shareholders and other customary closing conditions, will position Nuvation Bio as a late-stage global oncology company with multiple programs in clinical development. The Acquisition is expected to close in the second quarter of 2024.

"This transaction represents a significant milestone for our company and reflects Nuvation Bio's continued commitment to developing therapies for patients with the most difficult-to-treat cancers," said David Hung, M.D., Founder, President, and Chief Executive Officer of Nuvation Bio. "AnHeart's lead asset, taletrectinib, which will become our lead asset as it completes two pivotal studies, is a differentiated, next-generation ROS1 inhibitor with a potentially best-in-class profile that may overcome the significant limitations of existing therapies. We are impressed by what the AnHeart team has done to develop this asset and intend to build on the progress made to date."

Dr. Hung added, "Nuvation Bio is well capitalized, and this all-stock transaction maintains our robust cash balance and removes any need for near-term financing to develop both new assets and our current pipeline. With our combined talented teams and resources, we will continue to focus on executing the development strategy for our differentiated pipeline. We expect this deal will bring Nuvation Bio much closer to realizing our goal of delivering novel cancer therapies to patients, and we look forward to this exciting next chapter together with the AnHeart team."

"AnHeart, named for our deep sense of service to patients, has worked tirelessly over the past five years to advance our pipeline of next-generation precision oncology medicines. We are excited to continue our mission as part of Nuvation Bio given their shared vision to improve the lives of people with cancer," said Junyuan Jerry Wang, Ph.D., Co-Founder and Chief Executive Officer of AnHeart. "We believe the pipeline and financial strength of the combined company have the potential to create a market leader, and we look forward to working with David and the Nuvation Bio team to bring new cancer therapies to patients in need of better options."

Management and Organization

Nuvation Bio will continue to be led by its current management team, including David Hung, M.D., its Founder, Chief Executive Officer, and President, and expects AnHeart's employees in China and the United States to join the Nuvation Bio team. Following the closing of the Acquisition, Min Cui, Ph.D., Founder and Managing Director of Decheng Capital, an investor in AnHeart, and Junyuan Jerry Wang, Ph.D., Co-Founder and Chief Executive Officer of AnHeart, will join the Nuvation Bio board of directors.

Transaction Details

At the closing of the Acquisition, Nuvation Bio will issue to the AnHeart securityholders, in exchange for all outstanding AnHeart shares, options, and other securities, approximately 43,590,197 shares of Nuvation Bio's Class A common stock (inclusive of the shares of Class A common stock underlying the AnHeart equity awards to be assumed by Nuvation Bio), 851,212 shares of Nuvation Bio's Series A Non-Voting Convertible Preferred Stock, and warrants collectively exercisable for 2,893,731 shares of Nuvation Bio's Class A common stock at an exercise price of $11.50 per share.

Subject to approval by the Nuvation Bio stockholders (the Nuvation Bio Stockholder Approval), each share of Series A Non-Voting Convertible Preferred Stock issued by Nuvation Bio in the Acquisition will initially be convertible into 100 shares of Class A common stock. Additionally, the warrants issued in the Acquisition will be restricted until receipt of the Nuvation Bio Stockholder Approval. Any shareholders of AnHeart who are not accredited investors will receive cash for their AnHeart shares in lieu of receiving Nuvation Bio securities.

The holders of approximately 90% of AnHeart's outstanding shares have entered into voting agreements, pursuant to which they have agreed to, among other matters, vote in favor of the Acquisition.

In connection with the execution of the definitive merger agreement, Dr. Hung entered into a voting agreement, pursuant to which he agreed to vote his shares of Nuvation Bio stock, representing approximately 27% of Nuvation Bio's outstanding shares, for the Nuvation Bio Stockholder Approval. The closing of the Acquisition does not require the approval of the Nuvation Bio stockholders.

Nuvation Bio and AnHeart intend that the Acquisition will qualify as a tax-free reorganization. As AnHeart's parent company after the Acquisition, Nuvation Bio will own all of AnHeart's assets, including AnHeart's intellectual property.
