Seer, Inc. adopted a Tax Benefit Preservation Plan designed to protect its net operating losses and other tax attributes. The Board declared a dividend of one right for each outstanding share of Class A common stock to stockholders of record on March 9, 2026.
Each right allows the holder to purchase one one-thousandth of a share of Series A Participating Preferred Stock at an exercise price of $11.00. The plan is triggered if any person or group acquires 4.9% or more of Seer’s common stock without Board approval, creating significant dilution for the acquiror.
The rights are redeemable by the company for $0.001 per right and can be exchanged for common stock at one share per right in certain circumstances. The plan generally expires on February 25, 2029, but will terminate earlier if stockholders do not ratify it by February 25, 2027 or if the Board determines it is no longer needed to protect tax benefits.
