On April 16, 2012, the Company’s Ohio health plan, Molina Healthcare of Ohio, Inc. (“Molina of Ohio”), filed a formal administrative protest with the Ohio Department of Jobs and Family Services (“ODJFS”). The protest relates to the announcement on April 6, 2012 by ODJFS of its intended award of provider agreements pursuant to the Ohio Medicaid Managed Care Plan Request for Applications, Number JFS-R-1213-07-8019 (the “RFA”).

The principal grounds of Molina of Ohio’s RFA protest is that, in scoring certain portions of the Appendix D submission of Molina of Ohio, ODJFS awarded Molina of Ohio zero points for purportedly not following the instructions under Appendix D. Molina of Ohio believes and asserts in its protest filing that the instructions ODJFS had in mind in awarding Molina of Ohio zero points either do not exist, or require such a strained and unreasonable reading of the instructions as to make ODJFS’ conclusion clearly erroneous, and arbitrary and capricious. Molina of Ohio asserts that it did properly follow the explicit instructions of Appendix D. On that basis, and in the interest of fairness, Molina of Ohio requests that ODJFS re-score its Appendix D submission.

In the event ODJFS re-scores Appendix D and awards Molina of Ohio the points it had wrongfully withheld, Molina of Ohio believes it would be among the top five health plans by point total under the RFA in all three regions of the state, and therefore would be entitled to be among the health plans selected under the RFA.

In addition to its principal objection to the Appendix D scoring, the protest filing of Molina of Ohio also notes certain other procedural and scoring deficiencies under the RFA, and seeks relief in the alternative with respect to such other issues.

On April 16, 2012, the Company issued a press release announcing the protest filing by Molina of Ohio. The full text of the press release is included as Exhibit 99.1 to this report.

Note: The information furnished herewith pursuant to Item 7.01 of this current report and the exhibit attached hereto shall not be deemed to be “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, and shall not be incorporated by reference into any registration statement or other document filed by the Company under the Securities Act of 1933, as amended, or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.
