Quest Diagnostics, a leading provider of diagnostic information services, has agreed to acquire Haystack Oncology, an early-stage oncology company focused on minimal residual disease (MRD) testing. The all-cash equity transaction is expected to be completed in the second quarter of this year. After the acquisition, Quest plans to develop the MRD test that Haystack has developed as the basis for new clinical lab services that will become available in 2024. The initial focus will be on MRD tests for breast, colorectal and lung cancers. Quest will pay $300m in cash at closing, net of cash acquired, and up to an additional $150m on achieving future performance milestones.
Quest Diagnostics (NYSE: DGX), the nation’s leading provider of diagnostic information services, and Haystack Oncology, an early-stage oncology company focused on minimal residual disease (MRD) testing to aid in the early, accurate detection of residual or recurring cancer and better inform therapy decisions, today announced a definitive agreement for Quest to acquire Haystack in an all-cash equity transaction.
MRD testing is a fast-growing category of liquid biopsy tests that identify circulating tumor DNA (ctDNA) in the bloodstream of patients following surgery and treatment for cancer. Founded in 2021, Haystack has developed a ctDNA-based technology specifically for MRD detection, based on 20 years of research and development by world-renowned luminaries from Johns Hopkins University, including Drs. Bert Vogelstein, Ken Kinzler and Nick Papadopoulos. In a prospective, multi-institution study published in the New England Journal of Medicine in June 2022, an earlier version of the Haystack technology demonstrated the ability to better identify patients with residual disease for adjuvant chemotherapy after surgery for stage II colon cancer, thereby reducing chemotherapy use in the overall patient population without compromising recurrence-free survival.
Following the close of the acquisition, Quest expects to adapt the MRD test developed at Haystack as the basis for new clinical lab services available beginning in 2024. Development efforts will focus initially on MRD tests for colorectal, breast and lung cancers.

“We are excited by the opportunity to work together with Haystack Oncology, a company that we believe has developed a best-in-class ctDNA MRD technology,” said Jim Davis, Chairman, CEO and President, Quest Diagnostics. “Haystack’s liquid biopsy technology, combined with Quest’s strengths in screening, pathology and sequencing, will now position us to lead in the fast-growing MRD category. Working with Haystack, we have an opportunity to broaden access to MRD insights and potentially improve favorable long-term outcomes from cancer.”
“Combining Haystack with Quest is a major step forward in translating two decades of world-class liquid biopsy research and development into clinical laboratory services that are highly reliable and broadly accessible. Like looking for a needle in a haystack, accurately detecting MRD has been very challenging to date,” said Dan Edelstein, CEO and President, Haystack. “With Quest, we expect to increase and accelerate access to important tests that will improve the quality of cancer MRD detection and recurrence monitoring for patients. Working together, we have the potential to greatly transform the patient journey and save lives.”
The acquisition will leverage Quest’s expertise and scale in oncology, genomics and pathology. Quest employs approximately 400 pathologists through its AmeriPath specialty pathology-diagnostics business and provides approximately 7,000 patient access points in the United States for blood and other specimen collection. In addition, Quest’s expertise in next-generation tumor sequencing includes being able to identify patient-specific mutations for Haystack’s tumor-informed MRD approach. Quest also serves a broad swath of providers and connects with nearly 850 electronic health records systems, supporting convenient electronic longitudinal MRD reporting.
Under the terms of the agreement, Quest will pay $300 million in cash at closing, net of cash acquired, and up to an additional $150 million on achieving future performance milestones. The company expects the acquisition to be modestly dilutive to earnings over the next three years and accretive by 2026. The transaction is expected to be completed in the second quarter, subject to customary regulatory review.
