Stockholder Rights Agreement

 

On March 19, 2026, the Company's board of directors adopted a stockholder rights agreement and declared a dividend of one right (each, a “Right”) for each outstanding share of our common stock to stockholders of record at the close of business on March 30, 2026. Each Right entitles its holder, subject to the terms of the Rights Agreement (as defined below), to purchase from the Company one one-thousandth of a share of Series D Junior Participating Preferred Stock, par value $0.00001 per share, of the Company at an exercise price of $14.00 per Right, subject to adjustment. The description and terms of the Rights are set forth in a Rights Agreement, dated as of March 19, 2026 (the “Rights Agreement”), by and between the Company and Vstock Transfer, LLC, as rights agent. Subject to certain exceptions, Rights become exercisable and trade separately from our common stock only upon the earlier of (i) the close of business on the tenth business day following the public announcement of an Acquiring Person (as defined in the Rights Agreement) beneficially owning 10% or more of our common stock, and (ii) the close of business on the tenth business day after the commencement of a tender offer or exchange offer that, if consummated, would result in a person or group becoming an Acquiring Person. The Rights will expire on March 18, 2027, unless such Rights are earlier redeemed, exchanged or terminated, as provided in the Rights Agreement.

 

The Rights Agreement is intended to reduce the likelihood that any entity, person or group is able to gain control of the Company through open market accumulation without paying all stockholders an appropriate control premium or providing the board of directors sufficient opportunity to make informed judgments and take actions that are in the best interests of the Company and all stockholders. The Rights Agreement is not intended to interfere with any merger or other business combination approved by the board of directors.
