Sungrow Power Supply (300274.S
Cao Renxian is Sungrow's controlling shareholder and 实际控制人 (actual controller) — no corporate parent. GLEIF has no LEI record for the SZSE-listed parent entity itself (searched 'Sungrow Power Supply', 'Sungrow Power Supply Co', 'Sungrow'; only unrelated subsidiary/JV entities turned up, e.g. Sungrow (India) Private Limited, none reporting a parent relationship) — fell back to manual research. Stake figure varies slightly across secondary sources (~30.77% per English-language financial aggregators vs. 30.93% per the Chinese-language sponsor filing as of 2024-06-30); used the more primary, dated figure.
Named counterparties identified by open-source research and written only where a primary source states the relationship — never inferred from sector or co-mention. 13 suppliers, 4 customer-side. This is a partial view: it covers the relationships we could evidence, not the company's full supply base.
Rank-1 customer in the most recent (H1-2011) vintage, via solar-project subsidiaries Longyuan Golmud New Energy Development, Guodian Solar Energy System Technology (Shanghai) and Longyuan Tibet New Energy. 2010 Fortune Global 500 entrant.
Italian construction consortium (\"3C\", est. 1912, Bologna) — the largest single customer of any year in this filing; entered Italian solar EPC in 2009. No relationship found beyond the two years (2009-2010) the prospectus covers.
Wind-turbine OEM group; FY2009 rank-1 customer, fell to rank-5 by FY2010 (paired row below) — an 80%-relative decline in a single year.
FY2009 to FY2010: 19.36% to 3.81% (rank 1 to rank 5). No reason stated in the filing.
Per the filing, Infineon's (formerly Siemens Semiconductor) authorized first-tier China distributor and the largest China supplier of EUPEC-brand IGBT modules — the silicon-semiconductor die at the center of Sungrow's inverter/PCS products, then and now. share_pct computed from the filing's own disclosed supplier amount over its own disclosed 5-supplier subtotal for this table (RMB 254.51k/944.76k thousand); the filing gives absolute RMB, not a %, here.
1,810.47/3,784.28万元.
1,970.41/4,841.01万元 — remained rank-1 semiconductor supplier every vintage FY2009-H1 2011.
260.53/669.06万元. Per the filing this entity distributes Semikron power semiconductors under Arrow Electronics; renamed across the reporting period — see the FY2009/FY2010/H1-2011 rows below for the same lineage under its later names (理察森电子贸易(中国)有限公司, then 睿查森电子贸易（上海）有限公司).
478.44/944.76万元 — rank-1 this year, ahead of Beijing Jingchuan. Same lineage as the FY2008 Shenzhen-branch row above.
975.87/3,784.28万元.
1,663.70/4,841.01万元. Filing states this entity is 理察森电子贸易(中国)有限公司 renamed (\"现已更名为\") — same lineage as the three rows above, not a new entrant.
The SEPARATE general top-5-supplier table (different basis than the semiconductor-specific rows above: total company procurement, not the semiconductor-only subtotal) — rank-1 overall supplier, H1-2011.
331.38/669.06万元, rank-1. Per the filing, Mitsubishi semiconductor's authorized China agent.
60.45/944.76万元.
262.70/3,784.28万元. Dropped out of the top-5 by H1-2011 — right-censored, not a 0% row.
550.11/4,841.01万元. Unlike the distributor rows above, this is a direct branch of the German principal (SEMIKRON Group) — SEMIKRON also reaches Sungrow indirectly through 上海港基国际贸易 (a separate Semikron-module distributor named in the FY2009/FY2010 general-supplier tables, not captured as its own row here to avoid double-counting the same upstream principal).
387.82/4,841.01万元. Per the filing, Fuji Electric's authorized China/Hong Kong distributor for semiconductor devices.
Scope. Absence of a counterparty here is not evidence that none exists — most commercial sourcing is confidential and never becomes public. Rows without a share figure mean no share was disclosed, not that the relationship is small.
Another tracked dossier names this company as a counterparty in its own sourced disclosure — this platform never wrote these rows on this company's own page, they are read here inverted from the dossier that disclosed them. This is a partial view: 1004 additional named-counterparty rows across the corpus could not be matched to a tracked dossier by name at all (mostly non-Latin legal names), so the true count is higher than what renders here.
Sungrow IPO prospectus top-five supplier table. Share is of the BUYER's purchases, not of this seller's sales. Filing also lists it as rank-1 large power-semiconductor supplier in FY2009 (RMB 4.78m) and rank 2 in FY2010 and H1-2011; FY2009 overall rank 2 at 7.98% (as the pre-rename 理察森电子贸易(中国)有限公司).
Scope. This section is inverted evidence: each linked dossier wrote the original row about itself, describing its own relationship to this company. It is never a claim this company itself disclosed. Absence here is not evidence of no relationship — most of the corpus has no named-counterparty block at all yet.
Every exposure is read as a buyer dependency; the top 3 are its binding chokepoints.
As a buyer, policy pressure across its consumed materials is flat.
Descriptive trend in official policy actions on this company’s materials — a policy-pressure trend, not a price or trading signal. No forward probability is implied. Direction is measured on actions we have discovered, and discovery lags events: where the recent window is too thin to support a calm reading, the row says coverage-limited instead of easing.
No actions in the register have named or swept this company in the last 24 months.
