2025年5月17日，长盈通发布收购草案，拟以1.58亿元收购武汉生一升光电科技有限公司（下称"生一升 光电"）100%股权。其中，现金支付 1，738万元，股份支付14，062万元。 生一升光电主要从事无源光器件产品的研发、生产、销售和服务。截至评估基准日2024年12月31日，生 一升光电归属于母公司所有者权益账面值为 2，837.97万元，评估值为15，818万元，评估增值12， 980.03万元，增值率457.37%。 按1.58亿元收购价计算，生一升光电2024年静态市盈率高达57.6倍，远超行业均值。若业绩不达标，交 易对方仅需按差额补偿，但长盈通股东将承受商誉减值冲击。 生一升光电的估值溢价高达457.37%，但标的公司2023年亏损244.84万元，2024年仅实现净利润274.55 万元。 2023-2024年，生一升光电前五大客户销售额占比分别达98.08%和97.63%。尽管公司解释为"下游光模块 厂商集中"，但对比行业龙头中际旭创（前五大客户占比约70%），生一升的客户结构显然失衡。一旦 核心客户订单波动，其业绩将面临断崖式下滑风险。 作为收购方，长盈通自身的财务健康状况同样堪忧。 2 ...
