A battery supply chain company's growth curve looked like product-market fit. Most of it was a subsidy cycle with an expiration date.

What the Data Room Showed
Revenue had grown roughly 3x over two years, with a customer list that included several well-known domestic EV OEMs. The growth story presented in the deck attributed this to product performance and cost advantages versus competitors, a plausible and common narrative for the sector at this stage, supported by a technical benchmarking report from a reputable third-party lab showing the company's cell chemistry outperforming two named domestic competitors on energy density.
The company's finance team had prepared a detailed unit-economics model showing steadily improving gross margin per cell as manufacturing scale increased, a trajectory consistent with the kind of learning-curve cost reduction investors expect to see in a maturing battery manufacturer, and the model's assumptions on raw-material cost (lithium carbonate, cobalt) were reasonable against publicly tracked commodity price benchmarks at the time.
Management's forward plan called for continued domestic volume growth alongside a new export initiative targeting Southeast Asian and European EV assemblers, positioned in the deck as the natural next leg of growth once domestic manufacturing scale had been established — a sequencing story that read as sensible capital allocation logic to a Western growth-equity underwriting team.
The Structural Read
Capital Dependency
A majority of gross margin traced back to subsidy-linked contracts
55%
Of revenue tied to subsidy-linked anchor customers
Roughly 55% of the company's revenue came from three anchor customers whose own purchasing volumes were themselves shaped by provincial new-energy-vehicle subsidy targets. When the analysis modeled a scenario where two of those subsidy programs stepped down on their published schedules, the resulting margin compression was materially larger than what the deck's base case implied, because the deck's margin-improvement narrative had implicitly assumed the customers' own volume growth would continue on its recent trajectory independent of the subsidy support underwriting that trajectory in the first place.
Disaggregating the reported 3x revenue growth into a policy-enabled component and a genuinely market-driven component (attributable to product performance and cost advantage independent of the customers' own subsidy-linked demand) put the market-driven share at meaningfully less than half of the total growth, a distinction the pitch deck's single blended growth figure had not surfaced and that changed the appropriate framing for any forward revenue projection built on extrapolating the historical growth rate.
Governance
Two board seats were tied to the same subsidy relationship
Two of the seven board seats were held by individuals also affiliated with the local investment vehicle administering one of the subsidy programs, a connection not disclosed as a related-party relationship in the board composition summary provided to diligence, and only surfaced when beneficial-ownership tracing was run on both board members' other institutional affiliations rather than accepting their listed titles at face value.
This mattered directly for the capital-dependency finding above: the two board members with a direct institutional interest in the subsidy program's continuation would, in any future board discussion about diversifying away from subsidy-linked customers or relocating production to reduce exposure to a specific province's incentive terms, be voting on a question in which they held an undisclosed institutional interest, a conflict the standard board-independence disclosure had not been designed to catch because neither individual technically held an equity stake in the company itself.
Political Exposure
Export ambitions intersected with an evolving battery-materials control list
The company's stated path to margin diversification relied on export growth into Southeast Asia and Europe, using a cathode material process that had recently drawn attention under an updated technology export control list, a timing risk the growth projections did not account for, since the deck's export revenue build treated the necessary export licensing as a formality on the same order as a standard customs filing.
A comparison against two other domestic battery manufacturers' publicly reported experiences applying for comparable export licenses under the same updated control list showed a wide dispersion in approval timelines, from a fast-tracked several-week process to a multi-quarter review still pending at the time of the deal, with the deciding variable appearing to be the specific cathode chemistry and the destination country's own trade relationship with China at the time of application, neither of which the company's export plan had modeled as a variable risk.
The Structural Report Outcome
The report separated the growth story into its market-driven and policy-enabled components and modeled the subsidy step-down explicitly, rather than leaving it embedded in a single blended growth rate. It did not tell the committee whether the multiple being discussed was fair — that judgment stayed with the committee — but it gave them a base case they could stress-test on their own terms before that conversation.
On the board-composition conflict, the report recommended the two affected board members be formally recused from any future vote specifically concerning subsidy-program-related strategic decisions (customer concentration, manufacturing location), a narrower and more surgical remedy than requesting their removal from the board altogether, which the committee judged unnecessary given their otherwise constructive contribution to the board's work.
On the export-control timing risk, the report did not attempt to predict which approval-timeline scenario this specific company would face, since the available comparables did not point to a clear pattern the company's own circumstances would necessarily follow — instead, it recommended the committee treat the export-revenue line of the financial model as contingent rather than committed until the specific license application had been filed and an initial regulatory response received.
The committee proceeded with the investment at a valuation reflecting the market-driven growth component specifically, structured the board-recusal mechanism into an amended shareholder agreement, and required a licensing-status update as a standing quarterly board reporting item rather than a one-time closing condition, given the multi-quarter timelines observed in the comparable cases reviewed.
