20.69%这个数没错，产品结构和税费也都真在起作用，但这两条撞的不是同一行账——消费税压的是净利率，不进毛利率；真正把毛利率往下拽的是出口退税和产品结构，而且出口退税这一刀二季度就打完了，三季度环比再掉的那截，退税没份。
先把数对上。三季度单季营业收入1652.21亿元，营业成本1310.40亿元（前三季度3416.95亿元减去上半年2106.55亿元），单季毛利341.81亿元，除以收入得20.69%。比毛利率更刺眼的一个细节：二季度单季毛利342.17亿元，三季度只少了0.36亿元，可收入环比多了174.35亿元——多出来的收入几乎没带来多出来的毛利。
10月20日业绩说明会上有人问了同一个问题，董秘蒋理的原话是："产品结构的变化，一个季度的产品结构波动不代表长期方向"；"第二是消费税和出口退税的影响。我们正积极与客户沟通，一起来分担相关影响。"所以不是二选一，公司自己认的是两条。
出口退税走成本。财政部、税务总局2026年第2号公告，电池产品增值税出口退税率从9%降到6%，2026年4月1日起执行到年底。退税率降3个点，征退税差要转进营业成本。按上半年境外收入871.29亿元、占收入31.46%粗算，3%乘31.46%，对毛利率的影响上限约0.94个百分点——说是上限，因为境外收入里含海外工厂当地销售，不全是国内出口。关键在时点：二季度（4到6月）已经整个季度按6%跑，三季度税率没再动，所以三季度环比再掉的近2.5个百分点，不能记在退税头上。
消费税走税金及附加，不进营业成本。财政部、海关总署、税务总局2026年第20号公告，锂离子蓄电池2026年9月1日起按2%征消费税，2027年9月1日起提到4%，出口部分继续适用消费税退免税，因此只落在内销。报表上痕迹很清楚：单季税金及附加一季度6.38亿元、二季度6.87亿元、三季度22.14亿元，占收入比从0.46%跳到1.34%。这笔钱只影响净利率——三季度归母净利率12.86%，二季度15.26%，去年三季度17.80%。
产品结构这块，三季度动力加储能销量合计超过260GWh，储能占约四分之一，这是业绩会原话。但上半年分产品数据里，储能电池系统毛利率23.96%，比动力电池系统的20.63%还高3.3个百分点。所以"储能占比上升所以毛利率下降"这条链子，拿现有数据推不通。更站得住的是储能内部在从卖电芯、直流侧往交流侧和系统产品走，董秘自己说"相应的交付和确认收入周期比之前有所延长"，以及动力内部的车型结构下移。分产品毛利率要等年报才更新，三季度没法验证。
四季度会怎样。毛利率这一侧，四季度没有新的退税政策，6%执行到年底，消费税本来也不进毛利，所以税对毛利率的边际压力四季度不再加大。净利率还有两刀：消费税三季度只算了9月一个月，四季度是完整三个月，同口径下这块体量大约是Q3的三倍；2027年1月1日起电池出口退税直接取消，明年一季度成本还要再抬相当于6%出口收入的一截。毛利率会不会继续往下，取决于产品结构和价格，公司只给了"一个季度的产品结构波动不代表长期方向"和"正积极与客户沟通分担"，没给任何毛利率指引，任何具体数字都是猜。

300750: In Q3, the single-quarter gross margin fell to 20.69 — is it due to product mix or taxes and fees, and will it keep falling in Q4?
The 20.69% figure is correct, and both product mix and taxes and fees are genuinely at work, but these two hit different lines of the accounts — consumption tax squeezes the net margin and does not enter the gross margin; what actually drags the gross margin down is the export tax rebate and product mix, and the export tax rebate cut was already fully felt in Q2, so the further drop quarter-on-quarter in Q3 has no rebate component.
First, reconcile the numbers. Q3 single-quarter operating revenue was 1652.21 yi yuan, operating cost 1310.40 yi yuan (first three quarters 3416.95 yi yuan minus first half 2106.55 yi yuan), single-quarter gross profit 341.81 yi yuan, which divided by revenue gives 20.69%. One detail more striking than the gross margin: Q2 single-quarter gross profit was 342.17 yi yuan, and Q3 was only 0.36 yi yuan less, yet revenue rose 174.35 yi yuan quarter-on-quarter — the extra revenue brought almost no extra gross profit.
At the October 20 results briefing someone asked the same question, and board secretary Jiang Li's exact words were: "The change in product mix — a single quarter's product mix fluctuation does not represent the long-term direction"; "Second is the impact of consumption tax and the export tax rebate. We are actively communicating with customers to share the related impact together." So it is not either-or; the company itself acknowledges both.
The export tax rebate runs through cost. Ministry of Finance and State Taxation Administration Announcement No. 2 of 2026: the VAT export tax rebate rate for battery products drops from 9% to 6%, effective April 1, 2026 through the end of the year. A 3-point cut in the rebate rate means the difference between levied and rebated tax is transferred into operating cost. Roughly calculated on first-half overseas revenue of 871.29 yi yuan, 31.46% of revenue, 3% times 31.46% gives an upper limit of about 0.94 percentage points of impact on gross margin — an upper limit because overseas revenue includes local sales from overseas plants and is not all domestic exports. The key is timing: Q2 (April to June) already ran a full quarter at 6%, and the rate did not move again in Q3, so the nearly 2.5 percentage points of further quarter-on-quarter decline in Q3 cannot be booked to the rebate.
Consumption tax runs through taxes and surcharges and does not enter operating cost. Ministry of Finance, General Administration of Customs and State Taxation Administration Announcement No. 20 of 2026: lithium-ion batteries are subject to a 2% consumption tax from September 1, 2026, rising to 4% from September 1, 2027, with exports continuing to enjoy consumption tax refund/exemption, so it falls only on domestic sales. The trace in the statements is clear: single-quarter taxes and surcharges were 6.38 yi yuan in Q1, 6.87 yi yuan in Q2 and 22.14 yi yuan in Q3, with the share of revenue jumping from 0.46% to 1.34%. This money affects only the net margin — Q3 net margin attributable to parent was 12.86%, Q2 15.26%, and Q3 last year 17.80%.
On product mix, Q3 power plus energy storage sales totaled more than 260GWh, with energy storage about a quarter, per the exact words at the results briefing. But in the first-half by-product data, the energy storage battery system gross margin was 23.96%, 3.3 percentage points higher than the 20.63% of the power battery system. So the chain "energy storage share rose, therefore gross margin fell" cannot be derived from the available data. More defensible is that within energy storage the company is moving from selling cells and DC-side products to AC-side and system products — the board secretary himself said "the corresponding delivery and revenue recognition cycle has lengthened somewhat compared with before" — and that within power there is a downward shift in model mix. By-product gross margins will not be updated until the annual report; Q3 cannot verify this.
What about Q4. On the gross margin side, there is no new rebate policy in Q4, 6% runs through the end of the year, and consumption tax does not enter gross profit anyway, so the marginal pressure from taxes on gross margin does not increase further in Q4. The net margin still has two cuts: consumption tax was counted for only one month (September) in Q3, while Q4 is a full three months, so on a like-for-like basis this block is roughly three times Q3; and from January 1, 2027 the battery export tax rebate is cancelled outright, so cost in next year's Q1 must rise by another chunk equivalent to 6% of export revenue. Whether the gross margin keeps falling depends on product mix and price; the company gave only "a single quarter's product mix fluctuation does not represent the long-term direction" and "actively communicating with customers on sharing," and gave no gross margin guidance — any specific number is a guess.
