Recently, subsidiaries of a number of listed companies in the A-share market have launched capital increase and share expansion in order to obtain more financial support. According to the incomplete statistics of the Securities Times reporter, since November alone, more than 10 listed companies have issued relevant announcements on the introduction of strategic investors by subsidiaries, most of which are distributed in power equipment, pharmaceutical biology, basic chemical industry and other industries. It is worth noting that many of the strategic investors introduced by the subsidiaries of the above-mentioned enterprises are state-owned investment institutions. For this wave of "war-inducing" trend, people in the industry interviewed by reporters believe that due to the influence of relevant policies, listed companies have great resistance to spin-off and listing, which is an important reason for their subsidiaries to increase their capital and shares. Most of the targets that state-owned investment institutions choose to buy shares are new businesses or core businesses of hard-tech enterprises, which can not only ensure the safety of state-owned funds, but also obtain high premium returns in future IPO opportunities.
