Exhibit 99.1 Ciphergen Reports Second Quarter 2003 Financial Results Revenue Increased 65% vs. Year Prior Period FREMONT, Calif., July 24 /PRNewswire-FirstCall/ -- Ciphergen Biosystems, Inc. (Nasdaq: CIPH) reported financial results for the second quarter of 2003. For the quarter ended June 30, 2003, total revenue increased 65% to $14.3 million, up from revenue of $8.7 million in the second quarter of 2002. The increase in revenue was due to increased sales of ProteinChip(R) Systems and Arrays, increased sales of automation accessories, increased revenue from Ciphergen's BioSepra(R) Process Proteomics products, and increased revenue from service activities. Due to the litigation settlement achieved in the second quarter, Ciphergen recorded $7.3 million as a non-recurring expense which was recorded in cost of revenue. The Company reported a net loss of $15.6 million for the second quarter of 2003, compared to a net loss of $7.3 million for the comparable period of 2002. "We are pleased to report another strong quarter for Ciphergen, as our systems, consumables and services revenue continued to grow at a rapid rate. We continue to expand our business on all fronts including broadening our customer base, developing and launching innovative new products and strengthening our patent estate," commented William Rich, President and CEO of Ciphergen. "With the litigation behind us, and uncontested freedom to fully exploit the SELDI technology, we are expanding our business initiatives to other potentially lucrative markets including the discovery and development of protein-based clinical diagnostics and theranostics." Financial Impact of Litigation Settlement. Under the terms of the settlement, Ciphergen paid to LumiCyte $3 million in cash and issued 1.25 million shares of Ciphergen stock. In addition, Ciphergen will pay royalties of up to $10 million over a 10-year period to Molecular Analytical Systems. To account for these obligations, Ciphergen recorded during this quarter approximately $7.3 million in a non-recurring expense in cost of revenue. Ciphergen anticipates recording approximately $1.2 million per year in additional cost of revenue over the next 11 years with respect to this settlement. The following is a reconciliation of selected financial information prepared according to Generally Accepted Accounting Principles (GAAP) with selected non-GAAP financial information. Management believes that this adjustment for non-recurring expense associated with the litigation settlement enhances an investor's ability to compare the Company's results of operations for the three and six month periods ended June 30, 2003 to its results for historic and future quarterly periods. Management relies on this presentation internally for purposes of comparing such periods.

Although revenue continued to grow rapidly during the second quarter, Ciphergen's revenue reflected for the first time a softer purchasing environment in the U.S. We expect improving business conditions in the second half of 2003 in the U.S. and the Company continues to expect that 2003 revenue will be in the range of our original revenue guidance of $65-70 million. Summary Highlights for the Quarter: Litigation Settlement. Ciphergen cemented its rights to its core SELDI technology through a settlement with LumiCyte and Molecular Analytical Systems that provides Ciphergen with an exclusive worldwide license and the right to sublicense the technology and to commercialize any and all products, information and services derived from the technology without limitation. Expanding Biomarker Discovery and Diagnostic Commercialization in Cancer Research. -- 48 AACR Abstracts. 48 scientific clinical proteomics studies highlighting the use of Ciphergen's SELDI ProteinChip platform in cancer research were published in the proceedings of the American Association for Cancer Research's 2003 Meeting, nearly doubling the number of citations at last year's meeting. Many of the publications document new and exciting progress in early cancer detection, mechanisms of drug resistance, and correlation of genomic and proteomic data. -- Colon Cancer Collaboration with bioMerieux. Ciphergen also established a diagnostic biomarker discovery collaboration with bioMerieux S.A. by which the two companies will work together to discover biomarkers and multi-biomarker panels that may improve the diagnosis and management of colon cancer using Ciphergen's ProteinChip technology. -- ProteinChip Diagnostics Discovery and Commercialization Rights Licensed to Leading Canadian Clinical Research Group. Toronto Medical Laboratories (TML) has acquired Ciphergen's AutoBiomarker ProteinChip System along with discovery and commercialization licenses, with an objective of pursuing targeted assay development projects aimed at identifying new protein biomarkers that can be converted into commercial diagnostic tests in cancer and organ transplantation. Projects include TML and the McLaughlin Centre using the ProteinChip technology to conduct biomarker discovery and clinical studies on large organ transplant rejection markers, the early diagnosis of endometrial, thyroid and lung cancer, and the identification of predictors of response to novel therapeutic agents in colon cancer, leukemia and myeloma. Progress in SARS Research. Ciphergen's ProteinChip technology is being employed by multiple groups, including Health Canada's National Microbiology Lab, Beijing Clinical SARS Testing Center and the Genomic Institute of Singapore, in the hunt for novel protein biomarkers associated with Severe Acute Respiratory Syndrome (SARS). A number of potential biomarkers have already been discovered in SARS patient samples; these proteins are being identified and will be further evaluated for their utility in developing accurate diagnostic tests for SARS. If successful, therapeutic and/or vaccine strategies based on insights provided from these biomarkers may be pursued as well. New Product Introductions. During the quarter, Ciphergen launched its new Interaction Discovery Mapping(TM) (IDM) platform, representing a further development in Clinical Proteomics application tools that enables rapid protein interaction studies and complements our proven Expression Difference Mapping(TM) (EDM) capability for biomarker discovery and provides improved capabilities in functional proteomics applications.
