Behind Five Limit-Up Days, Dashengda (大胜达) Has 988 Million Yuan Worth of Blind Boxes Awaiting Unpacking

Stock rally tied to a risky GPU bet

A surprise pivot by Dashengda (大胜达, 603687.SH) — a listed paper‑packaging maker — has sent its shares into five limit‑up days, driven by what the company packages as a 988 million yuan deal: a 550 million yuan equity injection into Xintong Semiconductor (芯瞳半导体) plus a 438 million yuan share transfer by Dashengda’s controlling shareholder. Short and sharp. The move turned a conservative industrial issuer into a headline GPU investor overnight and prompted a regulatory query from the Shanghai Stock Exchange, it has been reported that the company is still preparing its formal replies.

Big valuation swings, thin disclosure

Investor alarms centre on a puzzling valuation gap in the package. Dashengda said it would buy legacy shares for 50 million RMB, implying a target valuation of 1.16 billion yuan, but the simultaneous 500 million‑yuan capital increase values Xintong at 20 billion — a jump of 8.4 billion yuan and a reported premium above 72 per cent. Dashengda’s filings say pricing was “negotiated” rather than set by a third‑party appraisal. Company staff acknowledged to reporters that a disclosure contained a literal wording error in the repurchase clause (a misplaced “not” reversed the meaning), and other core terms — timing for IPO or tape‑out conditions, what counts as “successful” flow‑testing, and triggers for buybacks — remain vague or omitted.

Technology, governance and the opaque counter‑parties

What is Xintong actually worth? It has been reported that the GPU developer, founded in 2019 in Xi’an and later moving HQ to Yantai and Xiamen, has two generations taped out but no third‑generation silicon in mass production; 2025 revenue is said to be only about 50 million yuan and net assets are reportedly negative. Industry sources told reporters the firm is “not well known” and “appears to lack major customers.” Governance risks multiply: Dashengda would become the second‑largest shareholder with substantial veto rights but without control, and the deal includes repurchase guarantees allegedly enforceable against the founder’s personal assets — a protection whose practical strength is unclear if the founder lacks sufficient resources. The strategic investor slated to buy 8% of Dashengda is a newly formed, low‑capital vehicle with two individual partners and little public track record, a detail likely to make institutional investors uneasy.

Strategic backdrop and a shareholder decision ahead

This is not just a corporate finance story. GPUs are geopolitically strategic amid tightened US export controls on advanced chips and Beijing’s push for domestic semiconductors, so valuations and transaction structures carry national‑tech significance as well as market risk. Dashengda’s shareholders will vote on the package at a meeting scheduled for April 3. Should they accept a transform‑the‑business deal built on big valuation swings, patchy disclosures and a raft of conditional clauses? The “blind boxes” are on the table — will investors unpack them or leave them closed?
