宁德时代(300750.SZ)投资备忘录

投资要点摘要

宁德时代是全球动力电池(市占率 39.2%,连续九年第一)与储能电池(市占率 30.4%,连续五年第一)的双料冠军。2025 年营收 4,237 亿元,归母净利 722 亿元(+42%),净利增速是营收增速的 2.5 倍,毛利率 26.3%、净利率 18.1%、ROE 约 25%,均为近五年最高。经营现金流 1,332 亿元,自由现金流约 911 亿元,现金储备近 4,000 亿元。连续三年以净利的 50% 分红,累计分红近千亿。

结论:公司质量 = 好,价格 = 合理偏低估。动作 = 可在 400 元以下分批买入,450 元以上观望或小幅减仓。

关键待验证问题: 固态电池产业化进度对现有液态产线的冲击、海外工厂(匈牙利 100GWh)投产后的实际盈利、储能业务增长持续性。

核心风险: 固态电池技术替代、地缘政治(美国关税、欧盟电池护照)、车企自研电池、行业产能过剩导致的降价压力。


一、商业模式与护城河

1.1 怎么赚钱

宁德时代是一家“卖铲子”的公司——下游车企和储能集成商抢市场,它卖电池。收入来自三个板块(均为 2025 年报数据,口径:年度/中国会计准则):

  • 动力电池系统:营收 3,165 亿元,占比 74.7%,同比 +25%,毛利率 23.84%。卖给全球主流车企(特斯拉、宝马、大众、蔚来、理想等),产品包括麒麟电池、神行超充、M3P、钠离子、凝聚态电池。citation

  • 储能电池系统:营收 624 亿元,占比 14.7%,同比 +9%,毛利率 26.71%(高于动力电池)。储能是利润质量最高的板块。citation

  • 电池材料及回收:营收 219 亿元,占比 5.2%,毛利率 27.27%。打通“矿产-材料-电池-回收”全链路。citation

地区上,国内营收 2,941 亿元(占 69%,毛利率 24%),境外 1,296 亿元(占 31%,毛利率 31.44%,比国内高 7.4 个百分点)。海外是高毛利引擎,但地缘风险也最大。citation

核心增长方程式:净利 = 出货量 × 单价 × 毛利率 − 固定成本。过去三年,出货量持续高增(2025 年 661GWh,+39%),毛利率逆势扩张(23%→24%→26%),规模效应使费用率下降,净利增速远超营收。

1.2 供给独占性——护城河在变强

逐项判断五大护城河来源:

  • 规模经济:产能 772GWh,产能利用率 96.9%,2026Q1 出货超 200GWh。citation 单位成本比同行低 10-20%,这是最硬的壁垒——对手要追上,需要千亿级资本开支 + 多年客户认证周期。citation

  • 转换成本:电池认证周期 18-24 个月,车企一旦选定供应商,切换成本极高。还与特斯拉、宝马等成立合资公司,“电池+底盘”集成方案进一步锁定客户。citation

  • 技术领先:累计研发投入超 900 亿元,全球专利超 5.4 万项,固态电池相关专利申请量全球第一(超 1,300 项)。citation 神行超充电池 12C(充电 5 分钟续航 520 公里),钠电池已量产上车,-40°C 仍保持 90% 电量。citation

How to quickly understand an industry

📋 User Guide: This Skill is an industry research engine driven by McKinsey methodologies, based on the eight-dimensional framework in Xiao Jing's "How to Quickly Understand an Industry." You tell it an industry name, and it generates a systematic industry research report for you. —————————————————————————————— 🚀 Basic Usage: Simply tell me what industry you want to research, the more specific the better: a. "Please analyze the solid-state battery industry for me" b. "Look at the humanoid robot industry chain from an entrepreneurial perspective" c. "Is the photovoltaic industry still worth investing in?" You can include three pieces of information (not mandatory, I will use the default if missing): 1. Industry Name: The more specific the better, such as "perovskite photovoltaics" rather than "new energy," this is "required"; 2. Goal: Investment/Career Selection/Entrepreneurship/Competitive Analysis/Popular Science, default: Investment; 3. Region: China Market/Global/USA/Southeast Asia..., default: China Market; —————————————————————————————— ⚙️ What will it do automatically? The entire process is divided into four stages: 1. Multiple rounds of online searches to gather evidence of market size/growth rate/penetration rate, industry chain, competitive landscape, moat, policies, and valuation—every conclusion has a source and timeframe, and is never fabricated; 2. Life cycle positioning: using penetration rate to determine whether the industry is in the introduction/growth/maturity/decline stage, with completely different research focuses at each stage; 3. In-depth analysis across eight dimensions: business model → market size → moat (mandatory in-depth analysis of dynamic trends) → competitive landscape (mandatory scoring of each of the five forces) → valuation → PEST analysis → business climate; 4. Anti-consensus testing: distinguishing between market-priced, obvious trends and overlooked real problems, and providing decision-making suggestions; —————————————————————————————— 📊 What will be produced? A professional industry research report in Markdown format is structured as follows: 1. ⚡ 30-Second Quick Assessment — Stage / Core Profitability Logic / Greatest Opportunity / Greatest Risk / One-Sentence Conclusion; 2. Research Subject and Boundary Definition; 3. Life Cycle Positioning (including penetration rate data); 4. Eight-Dimensional Item-by-Item Analysis (Moat includes dynamic trend table and Porter's Five Forces scoring table); 5. Anti-Consensus Test; 6. Conclusions and Decision Recommendations; 7. Key Risk List; 8. Data Sources and Time Explanation; —————————————————————————————— 🔑 Two Core Highlights 1. In-depth Moat Analysis: Not just discussing barrier types, but requiring an answer to "has it widened or narrowed in the past 2-3 years," using market share / gross profit margin / pricing power data; 2. Porter's Five Forces Scoring: All five criteria are assessed, leaving no room for shortcuts, determining who currently has the strongest bargaining power and whether the market structure is favorable or deteriorating for leading companies; —————————————————————————————— ⏱️ This takes approximately 2-4 minutes, as it requires multiple rounds of searching, dimension-by-dimensional analysis, and report writing. —————————————————————————————— 🧩 After the report output is expanded, we can continue with two specialized analyses (you will need to manually confirm these; they won't run automatically): 1. "Dissecting the Chain to Find Bottlenecks": Identifying unavoidable physical bottlenecks in the industry chain during a trend surge, and pinpointing the true beneficiaries; 2. "DCF Valuation": Running a complete discounted cash flow model for specific companies within the industry; —————————————————————————————— ▶️ Want to try? Just tell me an industry name, such as "Please take a look at the AI ​​Agent industry from a startup perspective" or "What's the current situation of the hydrogen energy industry chain?"
