SEATTLE, March 18, 2015 -- Juno Therapeutics, Inc. (JUNO), a biopharmaceutical company focused on re-engaging the body's immune system to revolutionize the treatment of cancer, today reported business highlights and financial results for the fourth quarter and year ended December 31, 2014.

"During the past year, we have made significant progress in building a world class science and clinical organization. We have leveraged our CAR and TCR technology platform to continue to develop cellular therapeutics with the potential to meaningfully improve the lives of patients with cancer," said Hans Bishop, Juno's Chief Executive Officer. "Our successful rounds of private financing, together with our IPO, have provided us with the financial resources that we need to continue advancing our product candidates. Within the next 12 months, we expect to have 10 product candidates in clinical development directed at six different cancer-associated antigens."

Non-GAAP Financial Measures

To supplement the financial results presented in accordance with generally accepted accounting principles in the United States (GAAP), Juno uses certain non-GAAP financial measures to evaluate its business. Juno's management believes that these non-GAAP financial measures are helpful in understanding Juno's financial performance and potential future results. These are not meant to be considered in isolation or as a substitute for comparable GAAP measures and should be read in conjunction with Juno's financial statements prepared in accordance with GAAP. These non-GAAP measures differ from GAAP measures with the same captions, may be different from non-GAAP financial measures with the same or similar captions that are used by other companies, and do not reflect a comprehensive system of accounting. Juno's management plans to use these supplemental non-GAAP financial measures internally to understand, manage, and evaluate Juno's business and make operating decisions. In addition, Juno's management believes that the presentation of these non-GAAP financial measures is useful to investors because they enhance the ability of investors to compare Juno's results from period to period and allows for greater transparency with respect to key financial metrics Juno uses in making operating decisions. Juno endeavors to compensate for the limitation of the non-GAAP measures presented by also providing the most directly comparable GAAP measures and descriptions of the reconciling items and adjustments to derive the non-GAAP measures. The following is a reconciliation of GAAP to non-GAAP financial measures:
