Using a classic strategy aimed at fending off unwanted takeover attempts, Riverbed Technology (UNKNOWN:RVBD.DL) has concocted a poison pill defense. The company announced that its board of directors unanimously approved a new stockholder rights plan. The initiative gives shareholders the right to acquire one one-thousandth of a share of new series A preferred stock at an exercise price of $75 per each share of common stock they own. Those rights kick in only if an investor gains a 10% stake in the company, or if an institution officially discloses a 20% position, without the approval of the board.
Although Riverbed did not specifically mention any investors in its press release, the poison pill is clearly a response to a disclosure by activist investor Elliott Associates last week that it had amassed a stake of roughly 9% in the company.
In releasing that disclosure, Elliott Associates described the technology firm's shares as "undervalued." The approximate 9% stake makes the investor Riverbed Technology's top shareholder.
