Building Membership Acquisition vs. Start-up: A Financial Perspective May 29th, 2008 Joseph White Chief Accounting Officer Molina Healthcare, Inc.

An HMO has four key financial assets: Regulatory Capital Member Contract Provider Network Administrative Capacity We can either buy these assets or we can build them.

How do we pay for an HMO? Administrative Capacity ACQUISITION START-UP Regulatory Capital Provider Network Member Contract Buy Buy Buy Buy Contribute Build Build Build

FINANCIAL STATEMENT IMPACT How do we pay for an Acquisition? Administrative Capacity ACQUISITION Regulatory Capital Provider Network Buy Buy Buy Buy Balance Sheet Investment Amortized Right Sized Amortized Member Contract

Start-Up Challenges Ohio: Growing enrollment while stabilizing medical costs

What do the financial statements look like? All of the costs that run through the income statement for a start-up: Membership growth; Provider network development; and Administrative ramp-up. . . . . . end up on the balance sheet for an acquisition!

So why do a start-up? Because it costs less!

Investment Comparison: New Mexico & Ohio Net Acquisition Costs(1) $55.3M Loss through Stabilization Period $1.7M Required Capital $43.2M Pre-Op Costs(3) $1.0M Loss during Membership Growth $9.8M Total Investment - $57.0M Cost per Member(2) = $877 ACQUISITION - NM Total Investment - $54.0M START-UP - OH Cost per Member(2) = $392 (1) Excludes $5.8M of debt held by target. (2) Represents total investment as a multiple of membership. The New Mexico acquisition resulted in 65,000 members. 138,000 were members enrolled in Ohio by end of the "growth phase" (June 30, 2007) . (3) Pre-operating costs do not include start-up costs at the parent company.

The Trade Off Administrative Capacity Provider Network Member Contract An HMO Needs BUY BUILD Initial operating profits are small Less expensive Takes time More expensive Almost immediate operating profits Faster

Who Cares About the Accounting? Start-ups and acquisitions have different accounting footprints Business needs drive the decision - we are indifferent to the accounting Start-ups have a lower Acquisitions cost more operating profit

The Decision Regulatory barriers to entry Number and strength of competitors Provider environment Length of state contracts Acquisition management talent Individual market dynamics determine whether we start-up or acquire:
