FOURTH QUARTER AND YEAR-END 2010 RESULTS

Fourth quarter earnings of $0.36 per diluted share;

Full-year earnings of $0.88 per diluted share

DENVER — Janus Capital Group Inc. (“JCG”) (NYSE: JNS) today reported fourth quarter net income of $65.9 million, or $0.36 per diluted share, compared with net income of $32.5 million, or $0.18 per diluted share, in the third quarter 2010 and net income of $37.0 million, or $0.20 per diluted share, in the fourth quarter 2009.

Fourth quarter 2010 includes a $0.02 per share operating benefit as a result of an insurance recovery related to the third quarter 2010 fund administrative errors and a $0.10 per share non-operating benefit from the sale of JCG’s structured investment vehicle securities, the reversal of income tax reserves and the cumulative effect of correcting a hedge accounting issue. Third quarter 2010 included a $0.05 per share operating charge for reimbursements to certain Janus mutual funds for two significant fund administrative errors and a $0.05 per share non-operating benefit for the reversal of income tax reserves.

For the full-year 2010, net income totaled $159.9 million, or $0.88 per diluted share, compared with a net loss of $757.1 million, or $4.55 per diluted share for 2009. Full-year 2009 included a net $5.03 charge per diluted share as a result of goodwill and intangible impairment charges, legal settlements, severance and a realized gain from the early retirement of debt.

The company’s operating margin for the fourth quarter 2010 was 34.7% compared with 23.4% for the third quarter 2010 and 30.2% for the fourth quarter 2009.

Flows and Assets Under Management

Average assets under management during the fourth quarter 2010 were $167.3 billion compared with $155.2 billion during the third quarter 2010 and $155.2 billion during the fourth quarter 2009.  At December 31, 2010, the Company’s total assets under management were $169.5 billion compared with $160.8 billion at September 30, 2010 and $159.7 billion at December 31, 2009.

The increase in complex-wide assets during the fourth quarter 2010 reflects $13.5 billion of net market appreciation, partially offset by long-term net outflows of $4.7 billion. Mathematical equity and fundamental equity (includes growth/blend, global/international and value investment disciplines) long-term net outflows totaled $2.6 billion and $2.7 billion, respectively, while fixed income long-term net inflows totaled $0.6 billion. Fourth quarter flows were heavily influenced by a single $2.6 billion fundamental equity redemption by an institutional client. The increase in year-over-year assets was primarily the result of $20.8 billion of net market appreciation and long-term net outflows of $10.8 billion.

Investment Performance

Long-term investment performance for fundamental equity mutual funds remained strong with 62% and 92% of mutual fund assets ranking in the top half of their Lipper categories on a three- and five-year total return basis, respectively, as of December 31, 2010.(1) As a result of underperformance in key fundamental equity strategies, the percentage of fundamental equity mutual fund assets in the top half of their Lipper categories on a one-year basis fell to 34% as of December 31, 2010, compared to 83% as of December 31, 2009.

Fixed income mutual funds continued to generate strong long-term investment performance despite short-term underperformance with 26%, 100% and 100% of mutual fund assets ranked in the top half of their Lipper categories on a one-, three- and five-year total return basis, respectively, for the same time period.(2)

Financial Discussion

Financial Highlights

(dollars in millions, except per share data or as noted)

Fourth quarter 2010 revenues of $275.7 million increased 13.1% from third quarter 2010 due to higher average assets under management and separate account performance fees. The fourth quarter 2010 includes $15.0 million of performance fees from one Janus-managed separate account which was terminated in December 2010. Fourth quarter 2010 operating expenses decreased $6.8 million, or 3.6%, from third quarter 2010 and include a $6.5 million insurance recovery related to two significant fund administrative errors which totaled $13.6 million in the third quarter 2010.

Non-operating items for the fourth quarter 2010 include a $5.8 million gain from the sale of JCG’s structured investment vehicle securities and a $5.4 million net benefit from the reversal of income

(3) For the period ending 12/31/2010, 75%, 25%, 0% and 50% of the mathematical equity mutual funds were beating their benchmarks on a 1-, 3-, 5-year and since-fund inception basis. Funds included in the analysis and their inception dates are: INTECH Risk-Managed Growth Fund — Class S (1/03); INTECH Risk-Managed Core Fund — Class T (2/03); INTECH Risk-Managed Value Fund —Class I (12/05); INTECH Risk-Managed International Fund — Class I (5/07).

(4) For the period ending December 31, 2010, 40%, 66% and 54% of Complex-Wide mutual funds had a 4- or 5-star Morningstar rating for the 3, 5- and 10-year periods based on risk-adjusted returns for 42, 38 and 28 funds, respectively. 42 funds were included in the analysis for the Overall period.

tax reserves following the expiration of statutes of limitations on tax positions taken in previous years. Additionally, the fourth quarter 2010 includes the cumulative effect of correcting the accounting for the hedge of mutual fund share awards. While changes in fair value of both the underlying awards and the hedge assets match at final vesting of the awards, they do not match in interim periods. As a result, JCG recognized $14.3 million of investment gains previously recorded as a liability on the Consolidated Balance Sheets.

Capital and Liquidity

At December 31, 2010, JCG had stockholders’ equity of $1.2 billion, cash and investments of $581 million and outstanding debt of $800 million. During the fourth quarter 2010, JCG exercised its call right on $121 million of debt, which was retired in January 2011. Under the terms of the call, JCG is required to pay the present value of the interest that would have been paid if the debt remained outstanding through maturity. As a result, JCG will take a charge of approximately $10 million in the first quarter 2011.

Subsequent to year end, JCG regained its investment grade rating from Standard & Poor’s, resulting in a 25 basis point decrease in interest rates on all of JCG’s outstanding Senior Notes. Annualized interest savings are expected to be approximately $1 million.

Investing involves risk, including the possible loss of principal. The value of your investment will fluctuate over time and you may gain or lose money. A fund’s performance may be affected by risks that include those associated with non-diversification, non-investment grade debt securities, high-yield/high-risk securities, undervalued or overlooked companies, investments in specific industries or countries and potential conflicts of interest. Additional risks to funds may include those associated with investing in foreign securities, emerging markets, initial public offerings, real estate investment trusts (REITs), derivatives, short sales and companies with relatively small market capitalizations. Please see a Janus prospectus for more information about risk, fund holdings and other details.

Lipper performance on an asset weighted basis is calculated by taking all funds and assigning the assets under management (“AUM”) in each respective fund to either the 1st, 2nd, 3rd or 4th quartile bucket based on each fund’s respective Lipper relative rankings.  The total AUM of each quartile’s bucket is then divided by complex-wide total AUM to arrive at the respective percent of AUM in each bucket. Lipper, a wholly-owned subsidiary of Thomson Reuters, provides independent insight on global collective investments including mutual funds, retirement funds, hedge funds, fund fees and expenses to the asset management and media communities. Lipper ranks the performance of mutual funds within a classification of funds that have similar investment objectives. Funds not ranked by Lipper are not included in the analysis.

The Overall Morningstar RatingTM for a fund is derived from a weighted average of the performance figures associated with its three-, five- and ten-year (if applicable) Morningstar RatingTM metrics. For each fund with at least a three-year history, Morningstar calculates a Morningstar RatingTM based on a Morningstar Risk-Adjusted Return measure that accounts for variation in a fund’s monthly performance (including the effects of sales charges, loads, and redemption fees), placing more emphasis on downward variations and rewarding consistent performance. The top 10% of the funds in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. (Each share class is counted as a fraction of one fund within this scale and rated separately, which may cause slight variations in the distribution percentages.) The Morningstar RatingTM may differ among share classes of a mutual fund as a result of different sales loads and/or expense structures. It may be based, in part, on the performance of a predecessor fund. Morningstar does not rank funds with less than a 3-year performance history.
