Private investment major Blackstone Inc is spearheading a $1.3bn private funding package to support the merger of Paratek Pharmaceuticals and Radius Health, according to a report by Bloomberg.
Blackstone Credit & Insurance structured the financing and acted as one of the largest lenders alongside Sixth Street Partners, which contributed over $400m. Additional participation came from Oaktree Capital Management and Silver Point Capital.
Jonathan Brayman, managing director at Blackstone Credit & Insurance, said the deal highlights the firm’s capacity to deliver large-scale capital solutions to life sciences companies. The transaction is part of a broader trend of private credit funds seeking lending opportunities outside software, where AI-driven disruption is reshaping the industry.
The combined entity is expected to generate approximately $1bn in revenue in 2026. Earlier this month, Blackstone also led a $100m private credit facility for genomic testing firm GeneDx.
