Humana Reports Fourth Quarter and Full Year 2012 Financial Results; Reaffirms 2013 Financial Guidance

• 4Q12 EPS of $1.19; FY12 EPS of $7.47, both above management’s expectations
• FY13 EPS guidance of $7.60 to $7.80 reaffirmed
• FY12 consolidated revenues grew 6 percent to over $39 billion
• FY12 cash flows from operations of $1.9 billion

LOUISVILLE, Ky.--(BUSINESS WIRE)--February 4, 2013--Humana Inc. (NYSE: HUM) today reported diluted earnings per common share (EPS) for the quarter ended December 31, 2012 (4Q12) of $1.19, compared to $1.20 per share for the quarter ended December 31, 2011 (4Q11). Results for 4Q12 were relatively unchanged versus those for 4Q11, but exceeded management’s previous expectations.

For the year ended December 31, 2012 (FY12) the company reported $7.47 in EPS compared to $8.46 for the year ended December 31, 2011 (FY11), which was higher than management’s previous expectations for FY12 EPS in the range of $7.25 to $7.35. FY12 consolidated results included $0.48 per share of benefit from favorable prior period medical claims reserve development compared to $0.77 per share in FY11.

The company continues to anticipate EPS for the year ending December 31, 2013 (FY13) in the range of $7.60 to $7.80 as improving operating results and modest accretion from the Metropolitan Health Networks, Inc. (Metropolitan) acquisition that closed in late FY12 are expected to be generally offset by slightly higher flu-related medical costs than previously anticipated, as well as additional interest expense associated with the company’s recent senior notes offering.

“The progress we made building our clinical capabilities in 2012 positions us strongly for success in 2014 and beyond,” said Bruce D. Broussard, President and Chief Executive Officer of Humana. “For 2013, we will continue to enhance our integrated care delivery model, which we believe represents the future of health care delivery, as we forecast another year of growth in revenues, earnings and Medicare membership.”

Consolidated Highlights

Revenues – 4Q12 consolidated revenues were $9.56 billion, an increase of 6 percent from $9.06 billion in 4Q11, with total premiums and services revenue up 5 percent compared to the prior year’s quarter. The year-over-year increase in premiums and services revenue was primarily driven by higher Retail and Employer Group segment revenues resulting from higher average individual and group Medicare membership, partially offset by the company’s new South Region TRICARE contract being accounted for as self-funded versus fully-insured for the previous contract. The new contract became effective on April 1, 2012.

FY12 consolidated revenues increased 6 percent to $39.13 billion from $36.83 billion in FY11 with total premiums and services revenue also up 6 percent compared to the prior year period, as a result of similar segment-level changes as those affecting the fourth quarter year-over-year change.

Benefits expense – The 4Q12 consolidated benefit ratio (benefits expense as a percent of premiums) of 83.7 percent increased by 190 basis points from 81.8 percent for the prior year’s quarter due primarily to a 360 basis point increase in the Retail Segment benefit ratio, as discussed more fully below.

The consolidated benefit ratio for FY12 of 83.7 percent increased by 160 basis points from the FY11 consolidated benefit ratio of 82.1 percent also primarily due to a 290 basis point increase in the benefit ratio for the Retail Segment.

Operating expenses – The consolidated operating cost ratio (operating costs as a percent of total revenues less investment income) of 17.5 percent for 4Q12 declined from 17.7 percent in 4Q11 primarily due to substantial reductions in this operating metric for the Retail and Employer Group Segments nearly offset by the impact of the accounting for the company’s new South Region TRICARE contract in the company’s Other Businesses.

The FY12 consolidated operating cost ratio of 15.1 percent increased 30 basis points from 14.8 percent for FY11 primarily due to the impact of the new South Region TRICARE contract discussed above, partially offset by lower year-over-year operating cost ratios for the Retail and Employer Group Segments.

Strategic transaction update – On December 21, 2012, Humana completed its previously disclosed acquisition of Metropolitan, a Medical Services Organization that coordinates medical care for Medicare Advantage and Medicaid beneficiaries, primarily in Florida.

Retail Segment Highlights

Pretax results:

• Retail Segment pretax income of $256 million in 4Q12 compares to $326 million in 4Q11, a decline of $70 million. This decrease was primarily due to a higher benefit ratio, partially offset by a lower operating cost ratio.
• For FY12, pretax earnings for the Retail Segment of $1.16 billion decreased by $425 million from FY11 pretax earnings of $1.59 billion. The full-year decrease reflects the same factors impacting the fourth quarter year-over-year comparison. FY12 Retail Segment pretax results included $110 million of benefit from favorable prior period medical claims reserve development compared to $147 million in FY11.

Enrollment:

• Individual Medicare Advantage membership was 1,927,600 at December 31, 2012, an increase of 287,300 members, or 18 percent from 1,640,300 at December 31, 2011, primarily due to a successful enrollment season associated with the 2012 plan year as well as age-in enrollment throughout the year.
• Effective March 31, 2012, the company added approximately 62,600 members from the acquisition of Arcadian Management Services, Inc. (Arcadian). As previously announced, the company divested 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.
• January 2013 individual Medicare Advantage membership approximated 2,011,000, up approximately 83,400 from December 31, 2012, reflecting net membership additions in line with the company’s expectations for the recently completed 2013 Annual Election Period (AEP) for Medicare beneficiaries and the Arcadian-related membership divestitures discussed above.
• Membership in the company’s individual stand-alone Prescription Drug Plans (PDPs) was 2,985,600 at December 31, 2012, up 445,200, or 18 percent compared to 2,540,400 at December 31, 2011. These increases resulted primarily from higher gross sales primarily during the 2012 enrollment season, particularly for the company’s innovative Humana-Walmart plan offering, supplemented by dual-eligible and age-in enrollments throughout the year.
• January 2013 individual stand-alone PDP membership grew to approximately 3,113,000, an increase of approximately 127,400 from December 31, 2012, in line with the company’s expectations for net additions during the AEP.
• HumanaOne® medical membership increased to 444,000 at December 31, 2012, an increase of 10,400, or 2 percent, from 433,600 at December 31, 2011.
• Membership in individual specialty products^(a) of 948,700 at December 31, 2012 increased 21 percent from 782,500 at December 31, 2011, driven primarily by increased membership in dental offerings.

Premiums and services revenue:

• 4Q12 premiums and services revenue for the Retail Segment was $6.11 billion, an increase of 15 percent from $5.31 billion in 4Q11. The increase was primarily the result of 19 percent higher average individual Medicare Advantage membership year over year.

Benefits expense:

• The 4Q12 benefit ratio for the Retail Segment was 82.6 percent, an increase of 360 basis points from 79.0 percent in 4Q11. The year-over-year increase was primarily due to a higher Medicare Advantage benefit ratio associated with new members and increased outpatient utilization for both new and existing members.

Operating costs:

• The Retail Segment’s operating cost ratio of 13.1 percent in 4Q12 decreased 160 basis points from 14.7 percent in 4Q11. The decrease was primarily the result of cost efficiencies resulting from higher average membership together with the company’s continued focus on operating cost efficiencies.

Employer Group Segment Highlights

Pretax results:

• Employer Group Segment pretax loss of $25 million in 4Q12 compares to a pretax loss of $51 million in 4Q11, and reflects an improved operating cost ratio partially offset by a year-over-year increase in the benefit ratio for this segment.
• For FY12, pretax earnings for the Employer Group Segment of $253 million increased by $11 million versus FY11 pretax earnings of $242 million with the same factors impacting fourth quarter results also driving the year-over-year increase.

Enrollment:

• Group Medicare Advantage membership was 398,500 at December 31, 2012, an increase of 80,300 members, or 25 percent, from 318,200 at December 31, 2011 primarily due to the addition of a large retiree account during FY12.
• Group fully-insured commercial medical membership increased to 1,211,800 at December 31, 2012, an increase of 31,600, or 3 percent, from 1,180,200 at December 31, 2011. This increase primarily reflected small group business membership gains partially offset by lower membership in large group accounts. Approximately 59 percent of group fully-insured commercial medical membership was in small group accounts at December 31, 2012 versus 56 percent at December 31, 2011.
• Group administrative services only (ASO) commercial medical membership declined to 1,237,700 at December 31, 2012, a decrease of 54,600, or 4 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) increased to 7,136,200 at December 31, 2012, an increase of 603,600, or 9 percent, from 6,532,600 at December 31, 2011. This increase primarily resulted from 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:

• 4Q12 premiums and services revenue for the Employer Group Segment were $2.63 billion, up approximately 14 percent from $2.30 billion in 4Q11 primarily reflecting the impacts of higher average group Medicare Advantage and commercial fully-insured membership.

Benefits expense:

• 4Q12 benefit ratio for the Employer Group Segment was 87.1 percent, an increase of 70 basis points from 86.4 percent for 4Q11. The year-over-year increase in the benefit ratio primarily reflected a higher percentage of members in group Medicare Advantage plans (which carry a higher benefit ratio than commercial fully-insured group accounts).

Operating costs:

• The Employer Group Segment’s operating cost ratio was 16.7 percent in 4Q12, a decline of 210 basis points from 18.8 percent in 4Q11, primarily reflecting a higher percentage of members in group Medicare Advantage plans (which carry a lower operating cost ratio than commercial fully-insured group accounts) as well as cost 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 $75 million in 4Q12 declined $10 million from $85 million in 4Q11 primarily due to transaction costs associated with the closings of the Metropolitan and MCCI Holdings, LLC (MCCI) strategic transactions announced in November 2012.
• For FY12, pretax earnings for the Health and Well-Being Services Segment of $486 million increased by $133 million from FY11 pretax earnings of $353 million, primarily from higher earnings in the company’s RightSource® mail order operations.

Revenues:

• Revenues of $3.26 billion in 4Q12 for the Health and Well-Being Services Segment increased 13 percent from $2.90 billion in 4Q11. This increase was primarily due to growth in the company’s pharmacy solutions business.

Operating costs:

• The Health and Well-Being Services Segment’s operating cost ratio of 96.8 percent in 4Q12 increased by 50 basis points from 96.3 percent in 4Q11, primarily due to costs associated with the 4Q12 closings of the previously announced Metropolitan and MCCI strategic transactions.

Other Businesses Highlights

Pretax results:

• Other Businesses incurred a pretax loss of $31 million in 4Q12 versus pretax income of $1 million in 4Q11, primarily due to a reserve strengthening for the company’s closed block of long-term-care business in 4Q12
• For FY12, a pretax loss for Other Businesses of $19 million compares to pretax income of $84 million in FY11. This year-over-year decline primarily reflected the combined effect of approximately $46 million in benefits expense related to the settlement of previously disclosed litigation involving Humana Military Healthcare Services, Inc., the 4Q12 adjustments to long-term-care reserves described above and the change in profitability under the new South Region TRICARE contract described below.
• 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.

Balance Sheet

• At December 31, 2012, the company had cash, cash equivalents, and investment securities of $11.15 billion, up approximately $320 million from $10.83 billion at December 31, 2011 reflecting higher balances associated with increased revenues for FY12 versus FY11.
• In early December 2012, the company announced it had completed its public offering of $1 billion of senior notes. A substantial portion of the proceeds from that debt offering was used to complete the Metropolitan transaction, including the retirement of Metropolitan’s indebtedness and for related transaction fees and expenses, all in late December 2012.

• Parent company cash and short-term investments of $346 million at December 31, 2012 decreased $176 million from $522 million at September 30, 2012, primarily reflecting strategic transaction activity and cash dividends to stockholders during 4Q12 partially offset by the net proceeds from the issuance of debt. Cash and short-term investments at the parent decreased $148 million year over year from $494 million held at the parent at December 31, 2011 as increased dividends from subsidiaries and net proceeds from the issuance of debt during 4Q12 were more than offset by strategic transaction activity, share repurchases and cash dividends to stockholders.
• Days in claims payable of 48.5 at December 31, 2012 decreased 3.1 days from 51.6 days at September 30, 2012 primarily due to a decline in processed and unprocessed claims on hand as well as certain provider capitation payment settlements during 4Q12.
• Debt-to-total capitalization at December 31, 2012 was 22.8 percent, up 710 basis points from 15.7 percent at September 30, 2012, and up 570 basis points from 17.1 percent at December 31, 2011 primarily driven by the 4Q12 issuance of senior notes described above.

Cash Flows from Operations

Cash flows provided by operations for 4Q12 were $205 million compared to cash flows used in operations of $1.80 billion in 4Q11. The company also evaluates operating cash flows on a non-GAAP basis:

The year-over-year increase in the non-GAAP cash flows from operations is due primarily to the effect on cash flows of changes in working capital accounts.

FY12 cash flows from operations of $1.92 billion compared to $2.08 billion for FY11, primarily due to lower net income year over year.

Share Repurchase Program

• During FY12, under the company’s current share repurchase authorization and a previously approved share repurchase authorization, the company executed share repurchases of approximately $460 million, or approximately 6,252,900 of its outstanding shares, at an average price of $73.66 per share.
• As of February 4, 2013, approximately $640 million of the $1 billion April 2012 share repurchase authorization remained, with an expiration date of June 30, 2014.

Footnotes

(a) The company provides a full range of insured specialty products including dental, vision and other supplemental health and financial protection products. Members included in these products may not be unique to each product since members have the ability to enroll in multiple products. Other supplemental benefits include life, disability, and fixed benefit products including cancer and critical illness policies.

(b) Generally, when the first day of a month falls on a weekend or holiday, with the exception of January 1 (New Year’s Day), the company receives this payment on the last business day of the previous month. Consequently, 4Q11 cash flows included two monthly Medicare payments compared to three monthly Medicare payments during 4Q12.

(c) The Company has included certain financial measures that are not in accordance with Generally Accepted Accounting Principles (GAAP) in its summary of financial results within this earnings press release. The company believes that these non-GAAP measures, when presented in conjunction with comparable GAAP measures, are useful to both management and its investors in analyzing the company's ongoing business and operating performance. Internally, management uses these non-GAAP financial measures as indicators of business performance, as well as for operational planning and decision making purposes. Non-GAAP financial measures should be considered in addition to, but not as a substitute for, or superior to, financial measures prepared in accordance with GAAP.

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 benefits expense 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, particularly its Medicare initiatives (given the concentration of the company’s revenues in the Medicare business), the company’s business may be materially adversely affected.
• 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, any of which, if resolved unfavorably to the company, could result in substantial monetary damages. Increased litigation and negative publicity could also 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-Qs for the quarters ended March 31, 2012, June 30, 2012 and September 30, 2012 (as amended by the Form 10-Q/A filed on December 4, 2012);
• Form 8-Ks filed during 2012 and 2013.
