Portland-based Foreside Financial Group LLC plans to acquire New Hampshire-based competitor NCS Regulatory Compliance for an undisclosed sum, the companies said Thursday.

Foreside, which has 150 employees, provides a range of services to the asset management industry. In 2017, Lovell Minnick Partners, a private equity firm based in Radnor, Pennsylvania, purchased a majority stake in the company and has since implemented a growth and expansion strategy, according to a news release.

NCS has about 80 employees and is based in Londonderry, New Hampshire. It provides outsourced compliance and regulatory services to the investment adviser and broker-dealer markets. Terms of the acquisition were not disclosed. The deal is expected to close this month.
