United Rentals Amends Shareholder Rights Plan

United Rentals, Inc. (NYSE: URI) today announced that its Board of Directors has amended the company's Shareholder Rights Plan to reduce the triggering threshold under the Plan to 15% from its previous level of 25%. As a result of the amendment, and subject to certain exceptions, the Rights will be triggered if a person or group acquires beneficial ownership of 15% or more of the company's common shares.

Any current holder of more than 15% of the company's common stock will not trigger the Rights, however, unless it subsequently acquires an additional .001% of the company's common shares.

The reduction of the company's unusually high triggering threshold was adopted in light of the current volatile state of the equity market and the company’s current lower share price. The company did not otherwise amend the Plan or extend its duration.

A copy of the amendment to the company's amended Shareholder Rights Plan is being filed on a Form 8-K today with the Securities and Exchange Commission.
