Triple-S Management Corporation Announces 12-Month Extension and Expansion of Puerto Rico MiSalud
Contract

SAN JUAN, Puerto Rico, June 27, 2013 — Triple-S Management Corporation (NYSE: GTS), the leading managed care company in Puerto Rico, announced that its Triple-S Salud subsidiary has reached an agreement for a 12-month extension of its contract with the Puerto Rico Health Insurance Administration (ASES) to administer healthcare services for the Government’s health insurance program known as MiSalud (Medicaid).

The MiSalud program serves more than 1.4 million members in eight regions across Puerto Rico. Under the 12-month extension, which commences July 1, 2013, Triple-S Salud will receive a per-member per-month administrative fee for its services and will not bear the insurance risk of the program. It will continue providing these administrative services in the five regions currently contracted with ASES and add the three remaining regions to its offering. The three additional regions will be phased in over the coming months, with expected completion by October 1, 2013.

Ramón M. Ruiz-Comas, President and Chief Executive Officer of Triple-S Management commented, “We are pleased to have not only extended our administrative services only (ASO) contract with the Puerto Rican government, but also broadened its geography to include all eight regions of the MiSalud program. In line with our commitment to work hand-in-hand with the Government to reduce delivery costs of this vital program without affecting healthcare benefits, we have made some concession on our administrative fees as part of the negotiation. Serving this important patient population remains a key component of our longer-term strategy and our commitment to social responsibility is a value that has been deeply woven into the fabric of our organization.”

Triple-S Management is currently evaluating the overall impact of the extension, geographic expansion and fee reduction of the MiSalud contract, in conjunction with other recent developments, and will provide a 2013 guidance update during its July 31, 2013 quarterly conference call.
