海尔企业有一个著名的原则，"没有现金流支持的利润就不算利润，没有利润支持的销售额就不算销售 额。" 至纯科技就是这样一家利润没有现金流支持的公司，尽管公司2024年经营活动现金流量净额已较上年同 期大幅收窄至-4.63亿元，但这种"纸面利润"的局面仍未改变。 证券之星吴凡 在半导体设备国产化浪潮中，至纯科技（603690）(603690.SH)近年的财务表现却呈现出"高光"与"隐 忧"并存的复杂图景。2017年上市以来，公司营收持续增长，至2024年创下历史新高的36.05亿元，然而 同期归母净利润却骤降93.75%至2359.75万元。今年一季度，公司颓势加剧，实现营收7.28亿元，同比 下滑10.32%，归母净利润1901.61万元，同比大幅下滑70.09%。 更大的隐忧在于，至纯科技净利润的含金量较低，属于典型的"纸面富贵"。2016年至2024年，公司经营 活动产生的现金流量净额持续为负，累计流出超过28亿元。这种净利润与现金流的严重背离的财务结 构，导致公司不得不高度依赖外部融资填补资金缺口。 截至今年一季度，公司短期借款＋一年到期的非流动负债合计约43.79亿元，货币资金仅有8.74亿元。除 长期 ...
