Citigroup is advising on the deal, one of the sources said.
Based in Santa Fe Springs, Calif., TwinMed is a medical supply distributor to nursing homes and alternate site markets. The company produced $278.6 million revenue in 2011, according to the Los Angeles Business Journal.
TA Associates acquired TwinMed in 2007. The firm paid $62.5 million, according to an SEC filing from that time. The investment came from TA’s 10th fund, which raised $3.5 billion in 2009.
Executives for TA and Citigroup declined to comment. TwinMed could not be reached for comment. – Luisa Beltran
