A Tender Offer is made when a company wants to takeover another company. The acquiring company will offer a price per share that is typically above the market price. You will be asked to tender, or surrender, your shares for the higher price. In reality, after the tender offer is made, the market price for your stock will usually go up and match the offer (if it doesn’t match the offer, there is some concern in the market that the deal may not go through).
