Seth Klarman Boosts Stake in Atara Biotherapeutics

Guru real-time pick highlight

April 10, 2018 | About:

Baupost Group manager Seth Klarman (Trades, Portfolio) disclosed on Monday that he increased his stake in Atara Biotherapeutics Inc. (NASDAQ:ATRA).

Trade details

Klarman invested in 895,000 shares of Atara for $39 per share. With this transaction, the manager expanded the portfolio 0.35%.


According to GuruFocus estimates, Klarman gained approximately 28% on the stock.


Company background

San Francisco-based Atara develops novel treatments for patients with cancer, autoimmune and viral diseases. GuruFocus ranks Atara’s financial strength 8 out of 10 as the company has no long-term debt and a robust Altman Z-score of 18.70.


Atara reported net losses of $119.50 million for fiscal 2017, up approximately $40 million from the prior year primarily due to higher research and development expenses.

CEO Isaac Ciechanover, M.D., said that the company “continued to advance its leadership in T-cell immunotherapy innovation” through several initiatives, including advancements in several off-the-shelf products. Throughout the past year, the U.S. Food and Drug Administration approved the company’s clinical trials for ATA188, a treatment for patients with multiple sclerosis. The company also initiated Phase 3 clinical studies for tab-cel, an off-the-shelf T-cell technology that can potentially treat patients with a “lifelong, asymptomatic infection” called Epstein-Barr virus.
