10月17日晚间公司公告称,公司控股股东杨竞忠与南京红太阳金控供应链有限公司签股权转让意向协议,杨竞忠拟将公司20%股份,以初步确认价20元/股,转让给南京红太阳。 该转让价较公司最新收盘价溢价%。 公告称,截至公告日,杨竞忠及其一致行动人顾瑜、杨经宇合计持有上市公司亿股,占公司股份总数的%。 若本次转让最终实施,杨竞忠持股比例将由原来的%降至%,公司控股股东及其一致行动人合计持股数量将降至%,没有导致公司控股权发生变更。

交易完成后,南京红太阳将成为上市公司第一大股东,其持股比例与公司实际控制人的持股比例较为接近,如公司实际控制人后续继续减持公司股份或南京红太阳后续继续增持公司股份,则存在可能导致公司实际控制权发生变更的风险。 公司表示,本次股权转让的目的是为了引进战略股东,以利于上市公司今后的业务发展。 但近期受公司股价下滑影响,公司管理层的质押融资压力不断加大。

截至9月1日公告,杨竞忠持有上市公司9477万股,占总股本的%,所持股份已累计质押6676万股,占上市公司总股本的%,占其持股总数的70%。 责编:罗懿。
