EXHIBIT 99.1 FOR IMMEDIATE RELEASE FOR FURTHER INFORMATION: INVESTOR RELATIONS & MEDIA: CORPORATE COMMUNICATIONS: COO & CFO: Amy Turner Amy Hedison John McCarthy Fleishman-Hillard EXACT Sciences EXACT Sciences P: (617) 267-8223 P: (978) 897-2800, ext. 252 P: (978) 897-2800, ext. 275 E: turnera@fleishman.com E: ahedison@exactsciences.com E: jmccarthy@exactsciences.com EXACT SCIENCES ANNOUNCES FIRST QUARTER 2003 RESULTS MAYNARD, MASS. - (APRIL 28, 2003) - EXACT Sciences Corporation (NASDAQ: EXAS) announced today financial results for the first quarter ending March 31, 2003. For the quarter ending March 31, 2003, revenues totaled $0.4 million, versus revenues of $0.04 million for the quarter ending March 31, 2002. Net loss for the first quarter of 2003 totaled $7.9 million, or $0.42 per share, compared to a net loss of $7.6 million, or $0.42 per share, for the first quarter of 2002. Pro forma net loss for the first quarter of 2003, which excludes $0.3 million of non-cash stock-based compensation charges, totaled $7.6 million, or $0.40 per share, compared to pro forma net loss of $7.0 million, or $0.39 per share for the first quarter of 2002, which excludes $0.6 million of non-cash stock-based compensation charges. Revenues for the first quarters ending March 31, 2002 and 2003 were primarily attributable to the amortization of upfront license fee payments related to the Company's two strategic partnerships with Laboratory Corporation of America(R) Holdings (LabCorp(R)), which were consummated in July 2001 and June 2002. Selling, general and administrative expenses for the quarter ending March 31, 2003, increased primarily due to increases in marketing and sales personnel and programs in preparation for the anticipated mid-year commercialization of PreGen-Plus(TM). As of March 31, 2003, EXACT Sciences had approximately $35 million in cash, cash equivalents and marketable securities available to fund its operations. "During the first quarter of 2003 we continued to lay the foundation for the commercial availability of PreGen-Plus, our non-invasive, DNA-based assay for the early detection of colorectal cancer," said Don Hardison, EXACT Sciences' President and CEO. "We anticipate that LabCorp will make PreGen-Plus commercially available by the middle of this year, and teams from both companies have been working very hard to ensure a successful launch. Pre-launch activities are on schedule, and I am extremely pleased with the progress to date. We believe that PreGen-Plus will not only be a tremendous step forward in colorectal cancer screening, but, in the end, will contribute to numerous lives being saved from this silent killer." OPERATING HIGHLIGHTS COMMERCIAL o Virtually all of EXACT Sciences' available resources are focused on working with LabCorp to prepare for the anticipated mid-year commercial availability of PreGen-Plus. Product launch activities currently underway include technology transfer and licensing, contracting with suppliers, physician education, demand creation, broad-based reimbursement initiatives, and sales force training. While some of these efforts will be ongoing after the launch of PreGen-Plus, others, such as the technology transfer and licensing and contracting with suppliers, must be completed prior to commercial launch. ALLIANCES AND BUSINESS DEVELOPMENT o EXACT Sciences signed an exclusive long-term licensing agreement with Johns Hopkins University relating to the digital-PCR technology developed by Dr. Bert Vogelstein's laboratory at the Johns Hopkins Kimmel Cancer Center. The Company believes that the agreement provides EXACT Sciences with a platform that, in conjunction with its proprietary technologies, may lead to future generations of PreGen-Plus. o The Company signed a manufacturing and supply agreement with Becton Dickinson relating to certain DNA isolation technologies that are proprietary to EXACT. These technologies provide for the isolation of target DNA sequences that are present in complex, heterogeneous, biological samples. CLINICAL o EXACT Sciences' multi-center study completed enrollment on March 28, 2003 with a final patient enrollment census of approximately 5,500. The Company expects that test completion by the final patients enrolled in the study should take approximately 12 weeks, which represents the Company's historical experience in the study. The Company expects that it will complete processing of the final samples by the end of the summer, and that results from the study will be available in the fourth quarter of 2003. o Overall, the Company has tested its PreGen(TM) technology on approximately 200 samples from patients with cancer across several different studies, excluding the multi-center study described above and the ongoing- Mayo/NCI study. Based on these studies, the average range of sensitivity for PreGen-Plus has been 65 - 70 percent for invasive colorectal cancer. In addition, to date, the results from these studies indicate a specificity of approximately 96 percent for PreGen-Plus. o The Company expects that clinical results on PreGen-Plus in more than 50 of these patients, and more than 100 patients with negative colonoscopy, will be published in the May issue of the journal, CLINICAL COLORECTAL CANCER. RESEARCH AND DEVELOPMENT o Six abstracts relating to various aspects of EXACT Sciences' PreGen technologies were accepted at this year's Digestive Diseases Week Conference, to be held in May in Orlando. Three of the abstracts were accepted for oral presentation, and the remaining three will be poster presentations.

EXACT Sciences has selected colorectal cancer as the first application of its technologies. Colorectal cancer is the most deadly cancer among non-smokers, and is curable if detected early. Despite the availability of colorectal cancer screening and diagnostic tests for more than 20 years, the rate of early detection of colorectal cancer remains low. EXACT Sciences believes its genomics-based technologies will enable early detection of colorectal cancer so that more people can be effectively treated. Founded in 1995, EXACT Sciences is based in Maynard, Mass.
