The agreement consists of a $100 million revolving credit facility, a $100 million initial term loan, and a $50 million delayed-draw term loan.
Proceeds from the loan facility will go toward the acquisition of Envigo's nonclinical research services business and other general corporate purposes.
The company drew $49 from the credit facility to repay an earlier outstanding loan and expects to draw another $27 million to, in part, pay for its acquisition of GenePOC.
The firm expects to offer nearly 5 million shares and also noted that this week it entered into an amended credit facility.
NanoString will initially draw $60 million at close, which will net it approximately $8 million after repaying its existing debt with the investment firm.
The new agreement amends a deal reached in October to partially fund its acquisition of some Alere businesses. That agreement was for $270 million.
NeoGenomics has now redeemed 100 percent of the $110 million preferred stock issues in conjunction with the Clarient acquisition, at a cost of $105 million.
The company will use a portion of the credit facility to fund its announced acquisition of Integrated DNA Technologies.
The company immediately borrowed $255 million to pay part of the $680 million price tag for Alere's MeterPro cardiovascular and toxicology business and its BNP assay business.
The firm said that it expects to use the proceeds of the senior notes offering to contribute to retirement of remaining convertible notes.
