Quest to acquire Northern Light Health's outreach laboratory business and professionally manage nine of its hospital laboratories

SECAUCUS, N.J. and BREWER, Maine, Dec. 8, 2022 /PRNewswire/ -- Quest Diagnostics (NYSE: DGX), the world's leading provider of diagnostic information services, and Northern Light Health, a large integrated healthcare system in Maine, today announced a strategic laboratory collaboration designed to broaden access to innovative, quality and cost-effective laboratory services powering affordable care for communities in Maine.

Under a definitive agreement, Quest will acquire select assets of Northern Light Health's outreach laboratory services business, named Northern Light Laboratory, in an all-cash transaction. Quest will also provide professional laboratory management services for nine of Northern Light Health's hospital laboratories, along with its cancer center laboratory at Northern Light Cancer Care in Brewer, Maine.

Northern Light Health selected Quest Diagnostics following a competitive bid. The parties expect to complete the transaction in the first quarter of 2023. Financial details of the transaction were not disclosed.

Assuming the transaction's completion, the collaboration will enable physicians and patients throughout Maine to benefit from access to Quest's industry-leading and highly innovative test menu, network of patient access sites throughout the state, broad health plan coverage, and lower out-of-pocket costs for many services. Quest's state-of-the-art laboratory in Marlborough, Mass. will provide non-urgent advanced and routine clinical testing for physicians and patients now serviced by Northern Light Laboratory. A Quest rapid response lab in the Bangor, Maine area and select Northern Light Health hospital labs will perform tests requiring rapid results.
