“squeeze out”和“sell out”指的都是为保护公司少数股东的权益而赋予其的权利。

squeeze out指强迫出售。

在公司章程允许的情下，代表公司股权90%以上的股东同意出售股份时，其可以要求小股东接受善意购买者提出的购买全部已发行股本的要约，但小股东有权要求以同等出售条件和出售价格出售其股权。其英文释义如下：

A squeeze-out or squeezeout, sometimes synonymous with freeze-out,[2] is the compulsory sale of the shares of minority shareholders of a joint-stock company for which they receive a fair cash compensation. This technique allows one or more shareholders who collectively hold a majority of shares in a corporation to gain ownership of remaining shares in that corporation. The majority shareholders incorporate a second corporation, which initiates a merger with the original corporation. The shareholders using this technique are then in a position to dictate the plan of merger. They force the minority stockholders in the original corporation to accept a cash payment for their shares, effectively "freezing them out" of the resulting company.

美国：美国联邦法没有明文规定强迫出售权，但是，美国有些州法允许收购方采用二次并购的方式来达到同样目的。如果收购方在第一次要约收购中取得了目标公司90％或以上投票权，收购方就可以再发起一次不需要股东投票决议的交易，将目标公司和自己的一个子公司进行合并。在二次收购中，收购方可以仅让目标公司寄给股东一个简短的信息通告而无需再次投票。如果异议股东对要约价格不满意，该股东可以向法院申请重新估价。

英国：英国规定如果收购方已收购到或达成了协议将会收购到代表目标公司股票价值和表决权90％以上的股票时，该收购方就有权在一定期限内要求剩余股东必须向其出售股票。

sell out指的则是强迫购买权。当收购方的股份达到一定比率后（比如90%），则剩余的股东权行使强迫购买权，将股份以一个合理的价格卖给收购方，退出公司。这个比率在各个国家有不同规定，收购方必须是以过去N个月的最高报价来收购剩余股份。这个条件的主要目的是确保收购方不利用他们的权利地位而牺牲了小股东的利益。The mandatory-bid condition through sell out rights allows remaining shareholders to exit the company at a fair price once the bidder has accumulated a certain number of shares. The amount of shares accumulated before the rule applies varies between countries. The bidder must offer the shares at the highest share price, as a minimum, which had been paid by the bidder previously. The main purpose for this condition is to ensure that the acquirer does not exploit their position of power at the expense of minority shareholders.
