"Wolfspeed股价飙了10倍！"最近碳化硅圈的消息让投资者眼前一亮，可老股东却笑不出来——这1000% 的涨幅，是破产重组后"旧股全额注销、新股重新定价"的表观数字，绝非真金白银的收益。 曾几何时，Wolfspeed是碳化硅"全球一哥"，手握200毫米晶圆独家技术，订单接到手软。但2025年上半 年，前管理层盲目扩张让它陷入破产保护，市场满是"一手好牌打得稀烂"的嘲讽。如今重组落地，股价 数字看似逆袭，可剥去"数字外衣"，它是真止血，还是仍在债务泥潭里挣扎？重组后的降本、技术家底 与订单潜力，才是"浴火重生"的关键。 01 从"破产倒计时"到"数字狂欢"：重组拆了哪三颗"炸弹"？ 去年此时的Wolfspeed堪称"内忧外患"：莫霍克谷工厂200毫米晶圆利用率跌到20%，开着机器就亏； 2025年Q3单季净亏2.86亿，毛利率-20.8%；5.75亿可转债违约，现金流濒临断裂。市场等着看"龙头退 市"，可短短数月，重组让它"改头换面"——9月29日退出破产保护，股价飙出10倍（需明确：这只是新 股换旧股的表观涨幅，非实际收益），背后是三个扎实的"拆弹"动作： 1）债务砍半：短期不用"卖厂偿债" 重组前，W ...
