DENVER — Janus Capital Group Inc. (“JCG”) (NYSE: JNS) today reported second quarter net income of $30.2 million, or $0.17 per diluted share, compared with net income of $31.3 million, or $0.17 per diluted share, in the first quarter 2010 and net income of $15.8 million, or $0.10 per diluted share, in the second quarter 2009.

The company’s operating margin for the second quarter 2010 was 24.6% compared with 27.3% for the first quarter 2010 and 23.5% for the second quarter 2009.

“Facing a very challenging environment, Janus demonstrated resiliency and made progress against strategic priorities including improved relative performance at INTECH, strong flows at Perkins, significant growth in its fixed income business, capitalizing on its successful U.S. retail franchise and strengthening institutional results at Janus and Perkins,” said CEO Dick Weil.

Flows and Assets Under Management

Average assets under management during the second quarter 2010 were $160.2 billion compared with $160.0 billion during the first quarter 2010 and $126.7 billion during the second quarter 2009.

The decrease in complex-wide assets during the second quarter 2010 reflects $17.0 billion of net market depreciation and long-term net outflows of $1.3 billion.  Mathematical equity and fundamental equity (includes growth/blend, global/international and value investment disciplines) long-term net outflows totaled $1.5 billion and $1.0 billion, respectively, while fixed income long-term net inflows totaled $1.2 billion. Fundamental equity flows were impacted by one significant equity mandate loss totaling $1.8 billion during the quarter.

Financial Highlights

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

Second quarter 2010 revenues of $249.3 million and average assets under management increased slightly from the previous quarter.  Operating expenses increased $8.3 million, or 4.6%, primarily as a result of fund proxy costs incurred in the second quarter 2010 and higher long-term incentive compensation, partially offset by a decline in administrative expenses.

Capital and Liquidity

At June 30, 2010, JCG had stockholders’ equity of $1.1 billion, cash and investments of $442 million and outstanding debt of $796 million.
