PIMCO Income Strategy Fund II Announces Results of Rights Offering

NEW YORK, April 26, 2010 (BUSINESS WIRE) –PIMCO Income Strategy Fund II (NYSE: PFN) (the “Fund”) announced today the results of its transferable rights offering (the “Offer”). The rights entitled holders to subscribe for an aggregate of 14,444,000 common shares of the Fund. The Offer, which commenced on March 24, 2010 and expired on April 23, 2010, was over-subscribed. The subscription price pursuant to the Offer was $8.45 per common share and was determined based upon a formula described in the offering materials equal to 90% of the average of the last reported sale prices of the Fund’s common shares on the New York Stock Exchange (“NYSE”) on the expiration date and on each of the four preceding trading days. Common shares subscribed for will be issued promptly after receipt of all shareholder payments and the pro-rata allocation of common shares in connection with the Offer’s over-subscription privilege.

Gross proceeds of the Offer are expected to be approximately $122 million. By increasing assets through the Offer, the Fund believes that it will be able to cost-efficiently shift investment allocations into fixed rate assets, further diversify the portfolio and potentially enhance risk-adjusted returns, consistent with its investment objective of high current income, consistent with the preservation of capital. The Offer was also intended to enhance the market liquidity of the Fund’s common shares, reduce the Fund’s expense ratio modestly (not taking into account interest expense) and provide common shareholders with the opportunity to buy additional common shares at a discounted price to then-current market value.

The Fund is a diversified, closed-end management investment company that seeks high current income, consistent with the preservation of capital. The Fund seeks to achieve its investment objective by ordinarily investing in a diversified portfolio of floating- and/or fixed-rate debt instruments.

There can be no assurance that the Fund will meet its objective. The Fund’s investment manager is Allianz Global Investors Fund Management LLC (“AGIFM”) and its sub-adviser is Pacific Investment Management Company LLC (“PIMCO”).

Shares of closed-end investment companies frequently trade at a discount to net asset value.
