Shares of Zim Integrated Shipping Services shares rose after the company said it had received several acquisition proposals.

The stock rose 13.58% to $22.58 in after-hours trading on Monday. Through the close, shares were down 7% this year.

The Israel-based logistics provider said the board of directors has received competitive proposals from multiple strategic partners to acquire the company. The proposals were part of a review of strategic alternatives that Zim has been undergoing.

Zim said it is evaluating the proposals with a focus on delivering value to shareholders.

The company also received a revised proposal from an entity owned by Chief Executive Eli Glickman. Zim's board concluded the proposal undervalued the company and informed the entity that it would decline the offer.
