Compulsory acquisition or public acquisition means that the acquirer and the acquiree do not agree on the purchase amount at the negotiation table, but the acquirer forcibly buys a large number of shares of the acquiree company in the stock market until the acquirer can obtain enough shares of the acquiree, convene a shareholders' meeting to re-elect the directors, and re-elect the chairman together with the personnel (and more than half) sent by the acquiree to the board of directors of the acquiree, and then clean or gather new management to obtain the acquiree company.

Not necessarily peers, in fact, some well-funded investment companies or fund companies can "lend a helping hand" by bidding for the shares of the acquired company so that the acquirer can't get enough shares (> 5 1%), but who will provide funds to the acquired company in vain? There must be promises and exchange of interests behind it, so some companies (such as my employer) may not choose to go public and issue shares if they are in good operating condition and have enough cash flow, so as to avoid heavy losses when they are attacked by "stock vultures".
