Dartmouth-Hitchcock Health and GraniteOne Health pursuing merger

New Hampshire-based health systems Dartmouth-Hitchcock Health and GraniteOne Health are planning to merge.

The two organizations announced on Friday that they signed a nonbinding letter of intent to combine their organizations as a nonprofit health system to be known as Dartmouth-Hitchcock Health GraniteOne. The signing of the letter of intent begins a process of due diligence which will include opportunities for public input, negotiation of the final terms, approval by each organization's leadership and the Bishop of Manchester and review by federal and state regulators.

Officials at both organizations said a combined health system would expand access to care for New Hampshire patients, including responding to growing demand for inpatient, specialty and subspecialty services in southern New Hampshire and extending healthcare services in rural communities.

Massachusetts and federal regulators gave the OK in 2018 for the planned merger of Beth Israel Deaconess Medical Center and Lahey Health. Bon Secours Health System and Mercy Health completed their $8 billion merger in September 2018.
