Exhibit 99.1 BioTime Announces Increased Revenues for Second Quarter 2004 * Total Revenues More Than Double During Second Quarter * 118% Increase in Royalty Revenue Recorded on Hextend Sales for Second Quarter * Regulatory Approval of Hextend in South Korea Received in July BERKELEY, Calif., Aug. 13 /PRNewswire-FirstCall/ -- BioTime, Inc. (Amex: BTX) today announced financial results for the second quarter ended June 30, 2004. Royalty revenues from Hextend(R) product sales by Hospira, Inc. increased 118% to $181,274 for the second quarter of 2004, from $83,234 during the same period last year. BioTime's total quarterly revenue more than doubled to $195,337 for the second quarter of 2004, from $97,297 for the same period last year. The Company recognizes royalty revenues in the quarter in which the sales report is received, rather than the quarter in which the sales took place. Therefore, revenues for the three months ended June 30, 2004 included royalties on sales made by Hospira during the three months ended March 31, 2004. BioTime received $145,208 in royalties from Hospira based on Hextend sales during the three months ended June 30, 2004. This represents an increase of 52% over royalties of $95,807 received during the same period last year. This revenue will be reflected in the Company's financial statements for the third quarter ending September 30, 2004. "The unit sales of Hextend in the second quarter were higher than the first quarter and the highest in the Company's history. Sales to the U.S. Armed Forces continued to contribute a significant portion of the increase," said Judith Segall, BioTime Vice President of Operations, Office of the President. "The balance of the improvement is due to increased hospital sales. Hextend has become the standard plasma volume expander at a number of prominent teaching hospitals and leading medical centers around the country. We believe that as Hextend use proliferates within the leading U.S. hospitals, other smaller hospitals will follow their lead and accelerate sales growth." During July, BioTime announced that its South Korean licensing partner CJ Corp. has received regulatory approval from the Korea Food and Drug Administration (KFDA) for Hextend. In addition, BioTime announced that it had received the second of two license fee installments from CJ Corp. This second installment totaling $300,000 was paid to BioTime in connection with CJ Corp.'s filing for regulatory approval to manufacture and market Hextend in South Korea. CJ Corp. is in the process of seeking Korean National Health Insurance pricing, which is necessary in order to begin marketing Hextend. This process is expected to be complete early next year. Research and development expenses for the second quarter of 2004 totaled $276,947, compared to $211,604 for the second quarter of 2003. The increase was primarily attributable to an increase in outside research costs and an increase in fees paid to scientific consultants. General and administrative expenses for the second quarter of 2004 totaled $366,334, compared to $378,567 for the same period last year. The decrease in general and administrative expenses is chiefly attributable to a decrease in accounting expenses and a decrease in travel and entertainment costs. These decreases were partially offset by increases in legal and investor/public relations expenditures. For the three months ended June 30, 2004, BioTime generated a total of $5,676 of net interest and other income with no offsetting interest expense, compared to net interest and other income of $4,841 during the same period last year, then offset by an interest expense of $264,319. The difference is due to the fact that during February 2004, the Company eliminated its $3,350,000 of debenture indebtedness by using a portion of the proceeds of its recently completed Rights Offer to repay $1,850,000 of debentures in cash, and by issuing a total of 1,071,428 common shares and 535,712 common share purchase warrants in exchange for $1,500,000 of debentures. BioTime reported a net loss of $(442,268), or $(0.02) per basic and diluted share, for the three months ended June 30, 2004, compared to a net loss of $(754,872), or $(0.06) per basic and diluted share, for the three months ended June 30, 2003. Cash and cash equivalents totaled $1,751,128 at June 30, 2004, compared with $717,184 at December 31, 2003. Total shareholders' equity was $1,332,906 at June 30, 2004, compared with total shareholders' deficit of $(2,430,551) at December 31, 2003. As of June 30, 2004, the Company had no long-term debt. Segall concluded, "Our financial results are evidence of the significant progress the Company made during the second quarter. And while I am proud of our accomplishments so far this year, I'm even more excited about the opportunities that lay ahead including the entrance of Hextend into South Korea, the increasing market penetration of Hextend in the U.S. and the commencement of Phase II clinical trials of PentaLyte(R) expected in the third quarter this year. These catalysts give us good operating momentum as we enter the second half of the year." About BioTime, Inc.
