EXHIBIT 99.1 Geron Corporation Reports 2004 First Quarter Financial Results and Events MENLO PARK, Calif.--(BUSINESS WIRE)--April 29, 2004--Geron Corporation (Nasdaq:GERN) today reported financial results for the three months ended March 31, 2004. For the first quarter of 2004, the company reported operating revenue of $248,000 and operating expenses of $52.3 million compared to $262,000 and $8.3 million, respectively, for the comparable period in 2003. Net loss for the period was $51.7 million or $(1.28) per share compared to $7.9 million or $(0.32) per share for the comparable period in 2003. The increase in first quarter 2004 operating expenses was attributable to a non-cash charge of $45.2 million to acquire in-process research technology, which resulted from the licensing of technology rights from Merix Bioscience, Inc. Excluding that charge, the company's overall operating expenses decreased in the first quarter of 2004 as a result of lower personnel-related costs and lower costs for raw materials to manufacture clinical trial drugs. In connection with the Merix transaction, Geron issued five million shares of its common stock to Merix in exchange for a co-exclusive right under patents controlled by Merix for the use of defined antigens in therapeutic cancer vaccines. The dendritic cell technology covered by the Merix patents is currently being used in conjunction with Geron's proprietary telomerase technology in a Phase I/II clinical trial underway at Duke University Medical Center. The addition of the Merix license to Geron's telomerase rights broadens the company's proprietary position in the technology being tested in this trial, and will serve as the foundation for Geron's work towards developing telomerase-based cancer vaccines. Geron maintains exclusive rights to the use of telomerase in these vaccines through its own patent estate. Except for payments that flow through to third party academic licensors from whom Merix originally obtained its rights, the license acquired by Geron is fully paid up. The company expects its research and development expenses to increase in the future as it continues pre-clinical manufacturing and testing of its telomerase inhibitor compounds, furthers the development of its human embryonic stem cell programs and expands its activities in the development of telomerase-based cancer vaccines. Revenues for the first quarter of 2004 and 2003 represented reimbursement for consulting agreements with various biotechnology companies, royalty revenues under various license agreements with companies for sales of telomerase-based diagnostic kits, shared profits from sales of reagent research products, and license fee revenues recognized from sublicense agreements or license option agreements with various companies for nuclear transfer and telomerase promoter technology. First Quarter 2004 Highlights: -- The Board of Patent Appeals and Interferences of the U.S. Patent and Trademark Office issued a decision on motions filed in the patent interference proceeding between Geron and Infigen, Inc. of DeForest, Wisconsin relating to nuclear transfer technology. The decision upholds the patentability of all of Geron's claims and finds all of the Infigen claims to be unpatentable. -- The Board of Patent Appeals and Interferences of the U.S. Patent and Trademark Office issued a final judgment ending the patent interference proceeding between Geron and Infigen, Inc. of DeForest, Wisconsin. The Board awarded judgment in Geron's favor on all counts in the interference. -- Geron acquired certain rights from Merix, as described more fully above. -- The Board of Patent Appeals and Interferences of the U.S. Patent and Trademark Office issued a decision on motions filed in the patent interference proceeding between Geron and Advanced Cell Technology Corporation of Worcester, Mass., relating to nuclear transfer technology. The decision finds all claims in the issued ACT nuclear transfer patent to be unpatentable. All motions filed by ACT were denied, including motions attacking the patentability of Geron's claims. -- Geron granted to Xcellsyz a nonexclusive license to Geron's human telomerase reverse transcriptase (hTERT) technology for research applications and the development of research products. -- Several presentations were made at the American Association for Cancer Research (AACR) Annual Meeting in Orlando, Florida of additional data from preclinical studies of GRN163L, a potent and specific telomerase inhibitor. The results presented confirm and extend the in vitro and in vivo efficacy of GRN163L in solid tumors, specifically liver and ovarian cancer, and report a sensitive, accurate, and reproducible assay for the detection of the drug in human blood. Geron is a biopharmaceutical company focused on developing and commercializing therapeutic and diagnostic products for cancer based on its telomerase technology, and cell-based therapeutics using its human embryonic stem cell technology.
