Description of Business

Atara Biotherapeutics, Inc. (“Atara”, “we”, “our” or “the Company”) was incorporated in August 2012 in Delaware. Atara is a leading off-the-shelf, allogeneic T-cell immunotherapy company that is developing novel treatments for patients with cancer, autoimmune and viral diseases. We have several T-cell immunotherapies in clinical development and are progressing a next-generation allogeneic chimeric antigen receptor T-cell, or CAR T, program.

We licensed rights to T-cell product candidates from Memorial Sloan Kettering Cancer Center (“MSK”) in June 2015 and licensed rights related to our next-generation CAR T programs from MSK in May 2018 and December 2018 and from Moffitt Cancer Center in August 2018. Additionally, we licensed rights to know-how and technology from the Council of the Queensland Institute of Medical Research (“QIMR Berghofer”) in October 2015, September 2016 and June 2018. See Note 6 for further information.

We have incurred significant operating losses since inception and have relied on public and private equity financings to fund our operations. As of June 30, 2019, we had an accumulated deficit of $667.6 million. As we continue to incur losses, our transition to profitability will depend on the successful development, approval and commercialization of product candidates and on the achievement of sufficient revenues to support our cost structure. We may never achieve profitability, and unless and until we do, we will need to continue to raise additional capital.

In July 2019, we completed an underwritten public offering of shares of common stock and pre-funded warrants and received aggregate net proceeds of approximately $140.6 million (see Note 10). Management expects that our cash, cash equivalents and short-term investments, together with the net proceeds from the underwritten public offering in July 2019, will be sufficient to fund our planned operations into 2021.
