JANUS CAPITAL GROUP INC. ANNOUNCES PRIVATE NOTE
EXCHANGE TRANSACTION

DENVER — Janus Capital Group Inc. (“JCG” or the “Company”) (NYSE: JNS) today announced that it has entered into separate privately negotiated exchange agreements pursuant to which $117 million aggregate principal amount of newly issued, 0.75% Convertible Senior Notes due 2018 (“New Notes”) will be exchanged for $110 million aggregate principal amount of the Company’s existing, 3.25% Convertible Senior Notes due 2014 (“Convertible Notes”).  Following these transactions, $60 million of existing Convertible Notes will remain outstanding.

The transaction takes advantage of favorable conditions in the marketplace and allows the Company to reduce its annual interest expense, extend the existing debt maturities and increase its financial flexibility.  The additional financial flexibility provided by the transaction will allow the Company to retire existing, long-term debt obligations should the opportunity arise in the future.

The New Notes will pay interest semiannually at a rate of 0.75% and will be convertible, under certain circumstances, into cash, shares of JCG common stock, or a combination of cash and shares of JCG common stock, at the Company’s election.  The initial conversion rate of the New Notes is 92.0598 shares of JCG common stock per $1,000 principal amount of New Notes, which is equivalent to an initial conversion price of approximately $10.86 per share of common stock, subject to adjustment in certain circumstances. This initial conversion price represents a premium of 25% relative to the closing price of $8.69 per share on June 13, 2013.

In connection with the offering of the New Notes, the Company has entered into privately negotiated convertible note hedge and warrant transactions, which in combination are intended to increase the effective conversion price under the New Notes to approximately $12.60, or a 45% premium relative to the closing price of $8.69 per share on June 13, 2013.  In the event that the warrant transaction is exercised, the Company intends to repurchase JCG common shares to offset resulting dilution. The repurchase of common shares will be at JCG’s discretion, subject to market and business conditions.

In connection with establishing its initial hedge of the convertible note hedge transaction and warrant transaction, the hedge counterparty and/or its affiliates expect to purchase JCG common stock in open market transactions and/or privately negotiated transactions and/or enter into various cash-settled derivative transactions with respect to JCG common stock concurrently with, or shortly after, the pricing of the New Notes. In addition, the hedge counterparty and/or its affiliates may modify their hedge positions by entering into or unwinding various derivative transactions with respect to JCG common stock and/or by purchasing or selling JCG common stock in open market transactions and/or privately negotiated transactions following the pricing of the New Notes from time to time (and are likely to do so during any averaging period related to a conversion of New Notes). Any of these hedging activities could also increase, decrease or prevent an increase or decline in, the market price of JCG common stock.

The New Notes were offered and sold in reliance on exemptions from registration requirements under the Securities Act of 1933, as amended, have not been registered under the securities laws of any state or other jurisdiction, and may not be offered or sold in the United States without registration or an applicable exemption under the Securities Act of 1933 and applicable state securities or blue sky laws and foreign securities laws.

This press release shall not constitute an offer to sell or a solicitation of an offer to buy any securities, nor shall there be any sale of securities in any state or jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such state or jurisdiction.
