Coursera said Monday that the plan will remain in place for one year and expire on Nov. 7, 2027. The company is issuing one right for each outstanding share of common stock.

If the rights become exercisable, holders could buy Coursera shares at a 50% discount to the current market price. Alternatively, Coursera may exchange each right for one share of its common stock.

The company said the plan is intended to guard against attempts to gain a controlling stake without paying all stockholders an appropriate premium.
