Humana Reports Third Quarter 2012 Financial Results, Issues 2013 Guidance, and Announces CEO Transition and Recent Strategic Transactions

• Third quarter EPS of $2.62, above previous guidance
• Full-year 2012 EPS guidance raised to $7.25 to $7.35
• EPS guidance issued for 2013 of $7.60 to $7.80 including $0.30 per share in investment spending
• President Bruce Broussard to become CEO effective January 1, 2013
• Strategic transactions with Metropolitan Health, MCCI and Certify Data Systems

LOUISVILLE, Ky.--(BUSINESS WIRE)--November 5, 2012--Humana Inc. (NYSE: HUM) today reported diluted earnings per common share (EPS) for the quarter ended September 30, 2012 (3Q12) of $2.62, compared to $2.67 per share for the quarter ended September 30, 2011 (3Q11), above previous guidance of $2.00 to $2.10. For the nine months ended September 30, 2012 (YTD12) the company reported $6.27 in EPS compared to $7.24 for the nine months ended September 30, 2011 (YTD11).

Results for 3Q12 reflect the beneficial impact of certain Part D and operating expenses shifting from the previously expected 3Q12 timing to the fourth quarter 2012 as well as the beneficial impact of favorable prior-year medical claims reserve development of approximately $0.21 per share in 3Q12 compared to $0.13 per share for 3Q11.

YTD12 results primarily were due to lower year-over-year operating results in the Retail Segment, partially offset by improved operating results in the Health and Well-Being Services Segment, as described in the segment-level discussions below. YTD12 results included the beneficial impact of favorable prior-year medical claims reserve development of $0.39 per share as well as $0.18 per share in expenses related to the previously-disclosed settlement of a litigation matter. YTD11 included $0.57 per share from the beneficial impact of favorable prior-year medical claims reserve development.

The company now anticipates EPS of approximately $7.25 to $7.35 for the year ending December 31, 2012 (FY12) versus its previous estimate of $6.90 to $7.10, driven primarily by favorable prior-year medical claims reserve development and improved stand-alone Prescription Drug Plan (PDP) results.

Looking ahead to the year ending December 31, 2013 (FY13), the company projects EPS to be in the range of $7.60 to $7.80, a growth rate of 5 percent at the mid-point versus the mid-point of the company’s FY12 EPS guidance. Results for FY13 are expected to include approximately $0.30 per share as the company accelerates investments in integrated care delivery models in key markets to ready itself for the future health care environment.

“Our third-quarter results demonstrate that the issues which surfaced in the second quarter have stabilized,” said Bruce D. Broussard, President of Humana. “We believe our improving operations and continued Medicare membership growth, together with our integrated care delivery system investments, position Humana well for a dynamic future.”

Chief Executive Officer Transition

As disclosed in November 2011, Michael B. McCallister, Humana’s Chairman and Chief Executive Officer, plans to retire as the company’s Chief Executive Officer. The company’s Board of Directors has appointed Bruce D. Broussard, the company’s President since December 2011, to become President and Chief Executive Officer effective January 1, 2013, completing the company’s year-long transition plan for the CEO position. At that time, Mr. Broussard will also join the company’s Board of Directors and Mr. McCallister will become non-executive Chairman of the Board of Directors.

“Long-term, we believe the company is poised for further growth under the leadership of our incoming CEO, Bruce Broussard,” said McCallister. “Bruce’s focus, energy, and effectiveness have been amply displayed in his tenure as Humana’s president.”

Strategic Transactions

Humana announced the following transactions today, each a strategic step in the company’s continued development of an integrated care delivery model.

• Metropolitan Health Networks, Inc. (NYSE: MDF) – The company announced that it has entered into a definitive agreement to acquire Metropolitan Health Networks, Inc. (Metropolitan), a Medical Services Organization (MSO) that coordinates medical care for Medicare Advantage and Medicaid beneficiaries primarily in Florida. Under the terms of the agreement, Humana will pay $11.25 per share in cash to acquire all of the outstanding shares of Metropolitan and repay all outstanding debt for an estimated transaction value of approximately $850 million plus transaction costs. The transaction is subject to Metropolitan shareholder approval as well as expiration of the Hart-Scott-Rodino anti-trust waiting period and is expected to close by the end of the first quarter of 2013. Humana expects to finance this transaction with a combination of cash and debt.
• MCCI Holdings, L.L.C. – The company has acquired a non-controlling equity interest in MCCI Holdings, L.L.C. (MCCI), an MSO headquartered in Miami, Florida that coordinates medical care for Medicare Advantage and Medicaid beneficiaries primarily in Florida and Texas. Terms of the transaction were not disclosed.
• Certify Data Systems – The company has acquired Certify Data Systems (Certify), a pioneer in health information exchange (HIE) technology. Certify’s HealthLogix^TM solution provides two-way sharing of clinical information across disparate electronic health-record systems, connecting healthcare providers and allowing them to share relevant patient health information in real-time. Terms of the transaction were not disclosed.

“Today we significantly advanced our strategy of aligning physician pay to quality through our investments in Metropolitan and MCCI. Combined with existing capabilities in our CAC and Concentra medical centers, Humana will soon employ or have strategic investments in medical practices that include nearly 2,300 physicians nationwide.” said Broussard. “The Certify acquisition furthers our integrated data platform through the real-time sharing of relevant health information at the point of care.

“Taken together, the three transactions we announced today unite key components of our integrated model, simplifying and enhancing our members’ health care experience.”

The company anticipates the cumulative impact of the transactions described above to be modestly accretive to its earnings for FY13 after giving effect to the related transaction costs.

Consolidated Highlights – Third Quarter 2012 Results

Revenues – 3Q12 consolidated revenues were $9.65 billion, an increase of 4 percent from $9.30 billion in 3Q11, with total premiums and services revenue also up 4 percent compared to the prior year’s quarter. The year-over-year increase in consolidated revenues was primarily due to related increases in the Retail and Employer Group segments primarily driven by higher average individual and group Medicare membership. These increases were partially offset by the company’s new South Region TRICARE contract being accounted for as self-funded versus fully-insured for the previous contract. This new contract became effective on April 1, 2012.

YTD12 consolidated revenues increased 6 percent to $29.57 billion from $27.78 billion in YTD11 with total premiums and services revenue also up 6 percent compared to the prior year’s period, driven primarily by the same factors as the third quarter year-over-year increase.

Benefit expenses – The 3Q12 consolidated benefit ratio (benefit expenses as a percent of premiums) of 82.2 percent increased by 150 basis points from 80.7 percent for the prior year’s quarter due primarily to higher year-over-year benefit ratios for the Retail and Employer Group segments. These increases were partially offset by a decrease in the impact of the benefit ratio for Other Businesses primarily due to the transition to the new administrative services only (ASO) South Region TRICARE contract on April 1, 2012.

The consolidated benefit ratio for YTD12 of 83.7 percent increased by 150 basis points from the YTD11 consolidated benefit ratio of 82.2 percent primarily due to the same factors impacting the year-over-year change for the third quarter.

Operating costs – The consolidated operating cost ratio (operating costs as a percent of total revenues less investment income) of 14.7 percent for 3Q12 compares to 14.8 percent in 3Q11 primarily reflecting substantially improved operating leverage nearly offset by the impact of the accounting for the company’s new South Region TRICARE contract in the company’s Other Businesses.

The YTD12 consolidated operating cost ratio of 14.3 percent increased by 40 basis points from that for YTD11 of 13.9 percent as the negative impact of the accounting for the company’s new South Region TRICARE contract was partially offset by improvements in operating leverage.

Retail Segment Highlights

Pretax results:

• Retail Segment pretax income of $424 million in 3Q12 decreased by $117 million from $541 million in 3Q11. For YTD12, pretax earnings for the Retail Segment of $906 million decreased by $355 million versus YTD11 pretax earnings for the segment of $1.26 billion. These decreases were primarily driven by year-over-year increases in the segment’s benefit ratios during 3Q12 and YTD12.

• Pretax income for the Retail Segment also included the beneficial impact of favorable prior-year medical claims reserve development of approximately $38 million in 3Q12 compared to $32 million in 3Q11. YTD12 pretax income included the beneficial impact of favorable prior-year medical claims reserve development of $95 million compared to $104 million in YTD11.

Enrollment:

• Individual Medicare Advantage membership was 1,911,800 at September 30, 2012, an increase of 298,400 members, or 18 percent from 1,613,400 at September 30, 2011 primarily due to a successful enrollment season associated with the 2012 plan year as well as age-in enrollment throughout the year. Individual Medicare Advantage membership has increased 271,500, or 17 percent, through September 30, 2012 from 1,640,300 at December 31, 2011.
• The individual Medicare Advantage membership changes described above include 12,100 members associated with the acquisition of MD Care effective December 30, 2011 and 62,600 members from the acquisition of Arcadian Management Services, Inc. (Arcadian) effective March 31, 2012. As previously announced, the company expects to divest approximately 12,600 members acquired with Arcadian effective January 1, 2013 in accordance with the company’s previously disclosed agreement with the United States Department of Justice.
• Membership in the company’s individual stand-alone PDPs was 2,947,200 at September 30, 2012, up 469,100, or 19 percent, compared to 2,478,100 at September 30, 2011 and up 406,800, or 16 percent, from 2,540,400 at December 31, 2011. These increases resulted primarily from growth in the company’s Humana-Walmart plan offering.
• HumanaOne® medical membership increased to 443,400 at September 30, 2012, an increase of 19,400, or 5 percent, from 424,000 at September 30, 2011 and an increase of 9,800, or 2 percent, from 433,600 at December 31, 2011.
• Membership in individual specialty products^(a) of 940,800 at September 30, 2012 increased by 185,200, or 25 percent, from 755,600 at September 30, 2011 and up 158,300, or 20 percent, from 782,500 at December 31, 2011. Both the sequential and year-over-year increases were primarily driven by increased sales in dental offerings.

Premiums and services revenue:

• 3Q12 premiums and services revenue for the Retail Segment was $6.14 billion, an increase of 14 percent from $5.40 billion in 3Q11. The increase was primarily the result of year-over-year membership growth for individual Medicare Advantage plans.

Benefit expenses:

• The 3Q12 benefit ratio for the Retail Segment was 82.3 percent, an increase of 360 basis points from 78.7 percent in 3Q11. The increase was primarily driven by a higher Medicare Advantage benefit ratio associated with new members and increased outpatient utilization for both new and existing members.
• Retail Segment prior-year favorable medical claims reserve development lowered the related benefit ratios by 60 basis points in both 3Q12 and 3Q11.

Operating costs:

• The Retail Segment’s operating cost ratio of 10.7 percent in 3Q12 decreased 50 basis points from 11.2 percent in 3Q11 reflecting cost efficiencies resulting from higher membership together with the company’s continued focus on operating cost efficiencies.

Employer Group Segment Highlights

Pretax results:

• Employer Group Segment pretax income of $43 million in 3Q12 compares to $46 million in 3Q11. For YTD12, pretax earnings for the Employer Group Segment of $278 million decreased by $15 million versus YTD11 pretax earnings for the segment of $293 million. These decreases primarily reflected year-over-year increases in this segment’s benefit ratio partially offset by lower operating cost ratios.
• Pretax income for the Employer Group Segment also included the beneficial impact of favorable prior-year medical claims reserve development of approximately $14 million in 3Q12 compared to $9 million in 3Q11. YTD12 pretax income included $4 million in unfavorable prior-year medical claims reserve development versus the beneficial impact of $42 million in favorable medical claims reserve development in YTD11.

Enrollment:

• Group Medicare Advantage membership was 395,700 at September 30, 2012, an increase of 80,200 members, or 25 percent, from 315,500 at September 30, 2011, and an increase of 77,500, or 24 percent, from 318,200 at December 31, 2011.
• Group fully-insured commercial medical membership increased to 1,204,500 at September 30, 2012, an increase of 23,200, or 2 percent, from 1,181,300 at September 30, 2011, and an increase of 24,300, or 2 percent, from 1,180,200 at December 31, 2011. Third quarter year-over-year and year-to-date changes primarily reflected growth in small group membership being partially offset by declines in large group business.
• Group ASO commercial medical membership was 1,231,100 at September 30, 2012, a decrease of 55,900, or 4 percent, from 1,287,000 at September 30, 2011, and a decrease of 61,200, or 5 percent, from 1,292,300 at December 31, 2011. This decline reflected a continuation of discipline in pricing services for self-funded accounts amid a highly competitive environment.
• Membership in Employer Group specialty products^(a) of 7,088,600 at September 30, 2012 increased 10 percent from 6,419,300 at September 30, 2011, and increased 556,000, or 9 percent, from 6,532,600 at December 31, 2011. Membership increases were primarily due to increased cross-sales of the company’s specialty products to its medical membership and growth in stand-alone specialty product sales.

Premiums and services revenue:

• 3Q12 premiums and services revenue for the Employer Group Segment were $2.64 billion, an increase of $325 million, or 14 percent, from $2.32 billion in 3Q11 due primarily to the result of increased group Medicare Advantage membership year-over-year.

Benefit expenses:

• 3Q12 benefit ratio for the Employer Group Segment was 85.3 percent, an increase of 180 basis points, from 83.5 percent for 3Q11. The year-over-year increase in the benefit ratio due to higher average group Medicare membership year-over-year. Group Medicare benefit plans generally carry a higher benefit ratio than commercial group medical products.
• Employer Group Segment prior-year favorable medical claims reserve development lowered the related benefit ratios by 60 basis points in 3Q12 and 40 basis points in 3Q11.

Operating costs:

• The Employer Group Segment’s operating cost ratio of 15.6 percent in 3Q12 improved 190 basis points from 17.5 percent in 3Q11 reflecting increased year-over-year membership in the company’s group Medicare Advantage products (which generally carry a lower operating cost ratio than the company’s fully-insured commercial group products) as well as savings associated with operating cost reduction initiatives.

Health and Well-Being Services Segment Highlights

Pretax results:

• Health and Well-Being Services Segment pretax income of $148 million in 3Q12 compared to $83 million in 3Q11. For YTD12, pretax earnings for the Health and Well-Being Services Segment of $411 million increased by $143 million versus YTD11 pretax earnings for the segment of $268 million. These increases primarily reflected growth in the company’s pharmacy solutions business, including higher script volumes within the company’s RightSourceRx® mail-order pharmacy.

Script volume:

• Script volumes for the Retail and Employer Group Segments’ membership increased to approximately 60 million in 3Q12, up 8 million, or 15 percent, versus 3Q11 scripts of approximately 52 million. The year-over-year increase primarily reflects growth associated with higher average medical membership for 3Q12 than in 3Q11 together with an increase in mail order penetration for the company’s medical membership year over year.

Services revenue:

• Services revenue of $3.20 billion in 3Q12 for the Health and Well-Being Services Segment increased 13 percent from $2.83 billion in 3Q11. This increase was primarily driven by growth in the company’s Medicare Advantage membership, who use the company’s pharmacy benefit management services under its health plan offerings, as well as higher script volumes for RightSourceRx mail-order pharmacy by the company’s membership across all product lines.

Operating costs:

• The Health and Well-Being Services Segment’s operating cost ratio of 94.6 percent in 3Q12 decreased 170 basis points from 96.3 percent in 3Q11. The decrease primarily reflects better operating cost leverage associated with higher script volumes in the company’s RightSourceRx mail-order pharmacy.

Other Businesses Highlights

• On April 1, 2012, the company’s new South Region TRICARE contract became effective with the Department of Defense (DoD). The company’s new contract is structured similar to self-funded products versus a fully-insured structure for the company’s previous South Region TRICARE contract with the DoD. This change resulted in significant volatility in year-over-year comparisons for the company’s Other Businesses during 3Q12 and YTD12.

Balance Sheet

• At September 30, 2012, the company had cash, cash equivalents, and investment securities of $11.26 billion, a decrease of $2.28 billion, or 17 percent, from $13.53 billion at June 30, 2012 primarily driven by the timing of the Medicare premium payment from the Centers for Medicare and Medicaid Services (CMS).
• Parent company cash and short-term investments of $522 million at September 30, 2012 decreased $758 million from $1.28 billion at June 30, 2012 primarily due to the 3Q12 share repurchase activity and cash dividends paid to stockholders during 3Q12. Completion of the SeniorBridge and certain other smaller acquisitions also contributed to the sequential decline in parent company cash and investments during 3Q12.

• Days in claims payable were 51.6 at September 30, 2012, up slightly from 51.0 at June 30, 2012.
• Debt-to-total capitalization at September 30, 2012 was 15.7 percent, down 40 basis points compared to 16.1 percent at June 30, 2012 primarily driven by higher capitalization associated with 3Q12 earnings.

Cash Flows from Operations

• Cash flows used in operations for 3Q12 of $1.33 billion compared to cash flows provided by operations of $2.92 billion in 3Q11. Cash flows provided by operations for YTD12 totaled $1.72 billion compared to $3.88 billion in YTD11. The company also evaluates operating cash flows on a non-GAAP basis:

The year-over-year decrease in the non-GAAP cash flows from operations is due to the negative effect on cash flows of changes in working capital accounts combined with lower net income year over year.

Share Repurchase Program

• During 3Q12, the company executed share repurchases of $234.3 million, or approximately 3,523,900 of its outstanding shares, at an average price per share of $66.50. As of November 5, 2012, approximately $640 million of the $1 billion April 2012 share repurchase authorization remained, with an expiration date of June 30, 2014.

Cautionary Statement

This news release includes forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. When used in investor presentations, press releases, Securities and Exchange Commission (SEC) filings, and in oral statements made by or with the approval of one of Humana’s executive officers, the words or phrases like “expects,” “anticipates,” “intends,” “likely will result,” “estimates,” “projects” or variations of such words and similar expressions are intended to identify such forward-looking statements. These forward-looking statements are not guarantees of future performance and are subject to risks, uncertainties, and assumptions, including, among other things, information set forth in the “Risk Factors” section of the company’s SEC filings, a summary of which includes but is not limited to the following:

• If Humana does not design and price its products properly and competitively, if the premiums Humana charges are insufficient to cover the cost of health care services delivered to its members, if the company is unable to implement clinical initiatives to provide a better health care experience for its members, lower costs and appropriately document the risk profile of its members, or if its estimates of benefit expenses are inadequate, Humana’s profitability could be materially adversely affected. Humana estimates the costs of its benefit expense payments, and designs and prices its products accordingly, using actuarial methods and assumptions based upon, among other relevant factors, claim payment patterns, medical cost inflation, and historical developments such as claim inventory levels and claim receipt patterns. These estimates, however, involve extensive judgment, and have considerable inherent variability because they are extremely sensitive to changes in payment patterns and medical cost trends.
• If Humana fails to effectively implement its operational and strategic initiatives, including its Medicare initiatives, the company’s business may be materially adversely affected, which is of particular importance given the concentration of the company’s revenues in the Medicare business.
• If Humana fails to properly maintain the integrity of its data, to strategically implement new information systems, to protect Humana’s proprietary rights to its systems, or to defend against cyber-security attacks, the company’s business may be materially adversely affected.
• Humana’s business may be materially adversely impacted by CMS’s adoption of a new coding set for diagnoses.
• Humana is involved in various legal actions and governmental and internal investigations, including without limitation, an ongoing internal investigation and litigation and government requests for information related to certain aspects of its Florida subsidiary operations, any of which, if resolved unfavorably to the company, could result in substantial monetary damages. Increased litigation and negative publicity could increase the company’s cost of doing business.
• As a government contractor, Humana is exposed to risks that may materially adversely affect its business or its willingness or ability to participate in government health care programs.
• Recently enacted health insurance reform, including The Patient Protection and Affordable Care Act and The Health Care and Education Reconciliation Act of 2010, could have a material adverse effect on Humana’s results of operations, including restricting revenue, enrollment and premium growth in certain products and market segments, restricting the company’s ability to expand into new markets, increasing the company's medical and operating costs by, among other things, requiring a minimum benefit ratio on insured products (and particularly how the ratio may apply to Medicare plans, including aggregation, credibility thresholds, and its possible application to prescription drug plans), lowering the company’s Medicare payment rates and increasing the company’s expenses associated with a non-deductible federal premium tax and other assessments; financial position, including the company's ability to maintain the value of its goodwill; and cash flows. In addition, if the new non-deductible federal premium tax and other assessments, including a three-year commercial reinsurance fee, were imposed as enacted, and if Humana is unable to adjust its business model to address these new taxes and assessments, such as through the reduction of the company’s operating costs, there can be no assurance that the non-deductible federal premium tax and other assessments would not have a material adverse effect on the company’s results of operations, financial position, and cash flows.
• Humana’s business activities are subject to substantial government regulation. New laws or regulations, or changes in existing laws or regulations or their manner of application could increase the company’s cost of doing business and may adversely affect the company’s business, profitability and cash flows.
• Any failure to manage operating costs could hamper Humana’s profitability.
• Any failure by Humana to manage acquisitions and other significant transactions successfully may have a material adverse effect on its results of operations, financial position, and cash flows.

• If Humana fails to develop and maintain satisfactory relationships with the providers of care to its members, the company’s business may be adversely affected.
• Humana’s pharmacy business is highly competitive and subjects it to regulations in addition to those the company faces with its core health benefits businesses.
• Changes in the prescription drug industry pricing benchmarks may adversely affect Humana’s financial performance.
• If Humana does not continue to earn and retain purchase discounts and volume rebates from pharmaceutical manufacturers at current levels, Humana’s gross margins may decline.
• Humana’s ability to obtain funds from its subsidiaries is restricted by state insurance regulations.
• Downgrades in Humana’s debt ratings, should they occur, may adversely affect its business, results of operations, and financial condition.
• Changes in economic conditions could adversely affect Humana’s business and results of operations.
• The securities and credit markets may experience volatility and disruption, which may adversely affect Humana’s business.
• Given the current economic climate, Humana’s stock and the stock of other companies in the insurance industry may be increasingly subject to stock price and trading volume volatility.

In making forward-looking statements, Humana is not undertaking to address or update them in future filings or communications regarding its business or results. In light of these risks, uncertainties, and assumptions, the forward-looking events discussed herein may or may not occur. There also may be other risks that the company is unable to predict at this time. Any of these risks and uncertainties may cause actual results to differ materially from the results discussed in the forward-looking statements.

Humana advises investors to read the following documents as filed by the company with the SEC for further discussion both of the risks it faces and its historical performance:

• Form 10-K for the year ended December 31, 2011;
• Form 10-Q for the quarters ended March 31, 2012 and June 30, 2012;
