The shareholder rights plan adopted by Southwest Airlines, also known as a "poison pill," is designed to make it more difficult and expensive for activist investor Elliott Investment Management to increase its stake in the company. This could potentially stabilize Southwest's stock prices by deterring any hostile takeover attempts or significant changes to the company's operations proposed by Elliott. However, the effectiveness of the plan and its impact on stock prices will depend on various factors, including market reactions and Elliott's future moves.
Elliott's letter to Southwest's board made three specific recommendations: 1) Enhance the Board of Directors with new, truly independent directors from outside of Southwest, 2) Upgrade Leadership with people from outside the company, and 3) Undertake a Comprehensive Business Review to evaluate all available opportunities to improve performance6.
A "poison pill" provision is a defensive strategy used by companies to prevent hostile takeovers. It involves making the acquisition financially unattractive for the potential acquirer by diluting their ownership or increasing the cost of acquiring the company. This is typically achieved by allowing existing shareholders, excluding the potential acquirer, to purchase additional shares at a discounted price4.
