Indianapolis, Ind. – November 2, 2016 – Anthem, Inc. (NYSE: ANTM) today announced that third quarter 2016 net income was $617.8 million, or $2.30 per share. These results included net negative adjustment items of $0.15 per share. Net income in the third quarter of 2015 was $654.8 million, or $2.43 per share, which included net negative adjustment items of $0.30 per share.

Excluding the items noted in each period, adjusted net income was $2.45 per share in the third quarter of 2016, a decrease of 10.3 percent compared with adjusted net income of $2.73 per share in the prior year quarter (refer to page 14 for a reconciliation to the most directly comparable measure calculated in accordance with U.S. generally accepted accounting principles, or “GAAP”).

CONSOLIDATED HIGHLIGHTS

Membership: Medical enrollment totaled approximately 39.9 million members at September 30, 2016, an increase of approximately 1.2 million members, or 3.1 percent, from 38.7 million at September 30, 2015. Commercial & Specialty Business enrollment increased by 656 thousand medical members as the Company experienced growth in the National and Local Group businesses. Enrollment also grew by 554 thousand in the Medicaid business.

Medical enrollment increased by 160 thousand members, or 0.4 percent, sequentially during the third quarter of 2016. The increase reflected enrollment gains in the Local Group and Medicaid businesses, partially offset by declines in the Individual and National businesses.

Operating Revenue: Operating revenue was approximately $21.1 billion in the third quarter of 2016, an increase of approximately $1.4 billion, or 6.8 percent, versus the nearly $19.8 billion in the prior year quarter. The growth in revenue reflected premium increases to cover overall cost trends and higher enrollment in the Medicaid and Commercial self-funded businesses. These increases were partially offset by a decline in Local Group fully insured enrollment.

Benefit Expense Ratio: The benefit expense ratio was 85.5 percent in the third quarter of 2016, an increase of 190 basis points from 83.6 percent in the prior year quarter. The increase was largely driven by the Medicaid business due to medical cost experience, notably in Iowa, exceeding the net impact of annual premium rate adjustments and higher membership, which carries a higher benefit expense ratio than the consolidated company average. Further, the benefit expense ratio reflects the impact of higher medical cost experience in the Individual business, partially offset by the timing of lower medical cost experience in the Local Group business, as expected.

Medical claims reserves established at December 31, 2015 developed moderately better than the Company’s expectation during the first nine months of 2016.

Medical Cost Trend: For the full year 2016, the Company continues to expect that underlying Local Group medical cost trend will be in the range of 7.0% - 7.5%.

Days in Claims Payable: Days in Claims Payable (“DCP”) was 40.6 days as of September 30, 2016, unchanged from 40.6 days as of June 30, 2016.

SG&A Expense Ratio: The SG&A expense ratio was 14.8 percent in the third quarter of 2016, a decrease of 80 basis points from 15.6 percent in the third quarter of 2015. The decrease was primarily driven by the impact of lower administrative costs resulting from expense efficiency initiatives and higher operating revenue, which includes the impact of membership growth in the Medicaid business, which carries a lower SG&A expense ratio than the consolidated Company average.

Operating Cash Flow: Operating cash flow was $964 million, or 1.6 times net income in the third quarter of 2016, and approximately $2.9 billion, or 1.4 times net income for the first nine months of 2016. The Company continues to expect its full year 2016 operating cash flow to be approximately $3.0 billion.

Share Repurchase Program: The Company did not repurchase any shares of its common stock during the third quarter of 2016 due to the pending acquisition of Cigna. As of September 30, 2016, the Company had nearly $4.2 billion of Board-approved share repurchase authorization remaining.

Cash Dividend: During the third quarter of 2016, the Company paid a quarterly dividend of $0.65 per share, representing a distribution of cash totaling $171.1 million.

On November 1, 2016, the Audit Committee declared a fourth quarter 2016 dividend to shareholders of $0.65 per share. On an annualized basis, this equates to a dividend of $2.60 per share. The fourth quarter dividend is payable on December 21, 2016, to shareholders of record at the close of business on December 5, 2016.

Investment Portfolio & Capital Position: During the third quarter of 2016, the Company recorded net realized gains on financial instruments totaling $88.8 million and other-than-temporary impairment losses totaling $11.0 million. During the third quarter of 2015, the Company recorded net realized losses of $11.9 million and other-than-temporary impairment losses totaling $19.1 million.

As of September 30, 2016, the Company’s net unrealized gain position in the investment portfolio was $982.6 million, consisting of net unrealized gains on fixed maturity and equity securities totaling $641.0 million and $341.6 million, respectively. As of September 30, 2016, cash and investments at the parent company totaled approximately $2.1 billion.

Reportable Segment Highlights

(Unaudited)

Commercial & Specialty Business: Operating gain in the Commercial & Specialty Business segment totaled $637.7 million in the third quarter of 2016, an increase of $18.5 million, or 3.0 percent, from $619.2 million in the third quarter of 2015. The increase was driven by lower administrative costs resulting from expense efficiency initiatives taken by the Company and the timing of lower medical cost experience in the Local Group business. This increase was partially offset by higher medical cost experience in the Individual business and fully insured membership declines in the Local Group business, as expected.

Government Business: Operating gain in the Government Business segment was $478.9 million in the third quarter of 2016, a decrease of $147.7 million, or 23.6 percent, from $626.6 million in the third quarter of 2015. The decrease reflected medical cost experience, notably in Iowa, exceeding the net impact of annual premium rate adjustments in the Medicaid business, partially offset by lower administrative costs resulting from expense efficiency initiatives taken by the Company.

Other: The Company reported an operating loss of $38.5 million in the Other segment for the third quarter of 2016, compared with an operating loss of $23.9 million in the prior year quarter. The increase in the loss was primarily driven by Cigna acquisition related expenses.
