Of the 27 companies in the index, 12 firms' share prices retreated last month, 14 companies' stocks increased, and one firm's share value was flat.
Much of the growth was driven by contributions from Genoptix, which NeoGenomics acquired in late 2018. Organically, revenues were up 20 percent.
The agreement consists of a $100 million revolving credit facility, a $100 million initial term loan, and a $50 million delayed-draw term loan.
The firm said that it may use some of the net proceeds to acquire or invest in complementary businesses and technologies.
The company, based in Fort Myers, Florida, said that it plans to use the net proceeds from the offering for general corporate purposes.
While the impact on participants' bottom lines remains to be seen, some lab company leaders said they expect to see other payors explore similar plans.
The firm's clinical service revenues were up also 51 percent, and it also announced it has signed a contract with insurer Humana.
The companies were involved in a dispute over NeoGenomics' handling of Health Discovery technology it licensed in 2012 to develop cancer tests.
Test volumes, revenues per test and costs per test improved during the quarter, company executives said.
