HealthSpring, Inc. To Acquire Leon Medical Centers Health Plans, Inc.

HealthSpring, Inc. (NYSE:HS) today announced that it has entered into a definitive agreement to acquire all of the outstanding capital stock of Leon Medical Centers Health Plans, Inc. ("LMCHP"), a Miami, Florida-based Medicare Advantage HMO with over 25,700 members.

HealthSpring will acquire privately held LMCHP for $355 million in cash at closing. HealthSpring intends to fund the acquisition with balance sheet cash and debt. The Company has entered into a $400 million commitment for a Senior Secured Credit Facility with Goldman Sachs Credit Partners L.P. with respect to the debt financing necessary to consummate the acquisition. The Facility includes a $100 million revolver that the Company expects to be largely unfunded at closing. The transaction is expected to be immediately accretive to earnings upon closing and, assuming the transaction closes as expected in 2007, should add at least $0.15 to the Company's 2008 diluted earnings per share.

As part of the transaction, HealthSpring will enter into an exclusive long-term provider contract with Leon Medical Centers, Inc. ("LMC"), an operator of five Medicare-only medical clinics located throughout Miami-Dade County. LMC has a ten-year history of providing exceptional quality of medical care and customer service to the Hispanic Medicare community of South Florida. Services offered in the medical clinics include primary care, specialty-care, dental, vision, radiology, and pharmacy services as well as transportation for members to the clinics. The provider contract also includes a risk-sharing arrangement whereby both HealthSpring and LMC will share equally in the surplus or deficit of the health plan relative to targeted medical loss ratios, which will be initially set at 80.0%.

The transaction consideration also includes the issuance into escrow of approximately 2.7 million shares that will be released from escrow in the event that LMC completes two additional medical centers before November 2009, subject to extension in certain circumstances. These new medical centers would provide additional capacity and geographic reach to support future membership growth in the health plan.

Commenting on the transaction, Herb Fritch, Chairman, President and Chief Executive Officer of HealthSpring, said, "The acquisition of Leon Medical Centers Health Plans gives HealthSpring an immediate and sizeable presence in the Florida Medicare Advantage market. We expect the transaction to have a positive impact on our growth and margins going forward. Not only are we adding over 25,700 Medicare HMO members, but we are entering into a long-term partnership with Leon Medical Centers, which has an impressive history of serving the needs of Miami's Medicare beneficiaries. We believe that their tightly integrated model of primary and specialty care services delivered in a medical clinic setting is a proven example of where the industry should be moving for the delivery of medical care to seniors in this country."

LMCHP has approximately 125 employees, all of whom are located in Miami. HealthSpring intends to maintain substantially the same health plan management team to continue to manage the plan. "Leon Medical Centers Health Plans is highly compatible with our existing operating structure," said Jerry Coil, HealthSpring's Executive Vice President and Chief Operating Officer. "Our mutual operating philosophies centered around physician engagement, medical management, and customer service should make for an easy transition. The addition of a substantial new market to our current operations should also have a stabilizing effect on our overall earnings from quarter to quarter."

In addition, Benjamin Leon, Jr., the founder of LMCHP and Chairman, Founder, and Chief Executive Officer of LMC, will be joining the HealthSpring board following the completion of the transaction. "Ben's demonstrated success in developing and operating medical centers specifically designed for Medicare beneficiaries will bring us key perspectives as we look to shape the future direction of HealthSpring," said Herb Fritch. "I look forward to working together to address the needs of Medicare beneficiaries across all of our markets."

For the first six months of 2007, LMCHP generated earnings before interest, taxes, depreciation and amortization expense of approximately $22 million on premium revenue of approximately $160 million. It is currently expected that premium revenue and earnings should be higher during the second half of the year.

The transaction is expected to be completed before the end of 2007, and is not subject to HealthSpring shareholder approval. It is subject, however, to other usual and customary conditions, including federal and state regulatory approvals.
