A flooring company facing three straight years of losses and with revenue nearing the delisting threshold is attempting an ambitious acquisition. The target is a PCB equipment maker with a modest first-half profit of 9.72 million yuan, and the deal involves paying a premium exceeding 20% of the buyer's net assets. This "snake swallowing elephant" transaction drew an immediate regulatory inquiry from the Shanghai Stock Exchange on the very night it was announced.
On the evening of September 18, Vohringer Home Technology Co., Ltd. announced plans to acquire a 51% controlling stake in Nanjing Kairuisi Automation Technology Co., Ltd. for 214 million yuan in cash. The seller is the company's existing owner, and the same evening, the exchange issued a supervisory work letter targeting the listed company, its directors, senior management, and its controlling shareholder. The urgency was clear from the start.
Losses Piling Up, Revenue Close to Red Line
Vohringer's core business revolves around wooden flooring, bespoke home furnishings, and doors, but this legacy enterprise is now deeply troubled. Financial reports show net losses attributable to the parent company from 2023 to 2025 were -16.55 million yuan, -37.99 million yuan, and -78.89 million yuan, respectively. This marks three consecutive years of widening losses, with the decline starting as far back as 2020. The non-recurring net profit has been negative for four straight years since 2022, accumulating a total loss of 162 million yuan.
The downward trend continued into the first half of 2026. Vohringer only managed to generate revenue of 96.3 million yuan for the period, a year-on-year drop of 30.42%. The net loss attributable to the parent company stood at -37.09 million yuan, with non-recurring net profit at -39.03 million yuan. Operating cash flow plummeted to -53.94 million yuan, a 269.58% year-on-year decline. All three subsidiaries focused on flooring and home furnishing are losing money, with one posting an 84.51% drop in first-half revenue. Gross margin figures paint an even more telling picture: it collapsed from 21.62% in 2021 to just 3.44% by 2025, and in the first half of 2026, it turned negative for the first time ever, hitting -1.90%, meaning the company is now losing money on every floor it sells. The net margin followed suit, dropping to -44.16%.
Vohringer's struggles are not unique in the industry. The deep adjustment in real estate has pushed the flooring sector into a period of consolidation, with production volumes sliding from 8.601 billion square meters in 2018 to 7.324 billion in 2025, a cumulative drop of 1.277 billion. Notably, Vohringer's 2025 revenue of about 365 million yuan sits dangerously close to the 300 million yuan delisting threshold. According to an industry analyst quoted in media reports, this deal is more about boosting revenue than achieving industrial synergy. The core business has failed to drive growth for three years, and with revenue hovering near the red line, the company is throwing cash at an unfamiliar sector to quickly inflate its top line.
An 80x PE Ratio Contradicts a 7x Profit Pledge
The valuation of this deal has raised eyebrows. Kairuisi, established in June 2017 with a registered capital of only 5 million yuan, develops and sells automation equipment for the lamination phase of PCB manufacturing. In 2025 and the first half of 2026, its revenue was 53.87 million yuan and 44.95 million yuan, respectively, with net profits of just 5.09 million yuan and 9.72 million yuan. Based on the 214 million yuan price for a 51% stake, Kairuisi is valued at approximately 420 million yuan, translating to a price-to-earnings ratio exceeding 80 times its 2025 profit.
What makes this high valuation more striking is the aggressive profit promise attached. The seller has committed to net profits of no less than 40 million yuan, 45 million yuan, 50 million yuan, and 50 million yuan for the years 2026 through 2029, totaling 185 million yuan. Achieving the 2026 target of 40 million yuan would require a roughly seven-fold increase over the 2025 profit of 5.09 million yuan. Based on the actual first-half profit of 9.72 million yuan, the company would need to more than triple its profit in the second half of the year to meet the full-year target. The agreement even includes a supplemental clause specifying that fourth-quarter 2026 main business revenue must be no less than 50 million yuan, with any shortfall to be compensated in cash by the seller. This structure suggests that both parties lack confidence in the target's ability to generate these profits naturally. An 80x PE ratio against last year's profit of just over 5 million yuan cannot be justified through normal operations, so the only way forward is to force the numbers through a guaranteed fourth-quarter revenue clause. With Kairuisi's net assets standing at only 24.91 million yuan as of June 30, 2026, the 420 million yuan valuation implies a staggering appreciation rate of 1,586.14% for what is essentially a light-asset equipment company.
Thin Technical Moat and a Clear Market Ceiling
Looking at the industry logic, the PCB lamination process Vohringer is entering is indeed a critical link in the AI computing hardware supply chain. Lamination is where inner core layers, prepreg, and copper foil are fused under high temperature and pressure, determining the layer count, reliability, and signal transmission loss of the final board. The AI server upgrade wave has pushed PCB technology demands higher, with layer counts rising from a typical dozen in standard servers to over 30 in AI servers, and some accelerator cards reaching 52 layers. This has driven significant growth in the export value of four-or-more-layer circuit boards, which jumped 47.74% year-on-year in the first half of 2026.
However, equating industry prosperity with Kairuisi's potential is a logical leap. The company itself acknowledges multiple risks. First, the market size has a clear ceiling. The global PCB lamination equipment market was approximately 3.878 billion yuan in 2025, and the specific processes Kairuisi focuses on—cutting, stacking, pre-laminating, and hot-melt/riveting—account for only about half of that, or less than 2 billion yuan. Second, Kairuisi has not yet expanded into higher-tech processes like hole punching, reflow, or lamination pressing, leaving it concentrated in lower-entry barriers segments that face intense competition. Industry insiders note that Kairuisi's products sit at the "light-asset" end of the PCB equipment chain, with core value in R&D, design, integration, and commissioning. While there is some room for domestic substitution in cutting and riveting machines, the technical moat is shallow and competition is fierce. The company currently holds 29 authorized patents, but more than 70% are utility models, with only seven invention patents and one design patent. Additionally, the downstream PCB demand is cyclical and currently at a high point; any downturn would directly impact orders, revenue, and margins.
Zero Experience in PCB Sector, Market Votes With Its Feet
Upon completion of this transaction, Vohringer is expected to add approximately 200 million yuan in goodwill, which exceeds 20% of its net assets at the end of 2025. Any impairment of this goodwill due to poor performance or industry shifts would severely damage the listed company's earnings. The cross-industry integration challenge is even more direct. Vohringer has explicitly admitted in its announcement that it has no operating experience, technical expertise, or management and market talent in the PCB equipment field, creating substantial integration risks.
Investors should also note that Vohringer has reserved a follow-up acquisition arrangement. If Kairuisi secures 200 million yuan in new orders in 2027, obtains a formal order for its lamination press, or fulfills its 2026-2028 profit promises, Vohringer is obligated to initiate the purchase of the remaining 49% stake. The valuation for this second phase would be based on a multiple of no less than 10 times the average net profit over the three-year guarantee period. This implies significant future capital expenditure if the first deal goes through.
In the lead-up to this announcement, Vohringer also revealed shareholder sell-offs. Between July and September 2026, the second largest shareholder reduced its holdings by 5.4554 million shares, cashing out 245 million yuan. A vice general manager also sold 44,000 shares for 2.17 million yuan. Although both parties later terminated their reduction plans early, the selling activity itself has fueled market skepticism.
The market's reaction was swift and unforgiving. On September 21, Vohringer's shares fell 6.42% with a trading volume of 473 million yuan and a daily amplitude of 11.24%. The next day, the stock hit the daily limit down, closing at 32.91 yuan, a 10.01% drop, shrinking its market cap to 11.241 billion yuan. The day saw net institutional selling of 31.77 million yuan and main force capital outflows of 97.75 million yuan. Over five trading days, cumulative main capital outflows reached 146 million yuan. This two-day sell-off reflects clear market rejection of the deal.
It's worth noting that from the announcement of a control change on June 6, 2025, until the acquisition disclosure on September 18, the stock had already surged over 293%. The market is now using the acquisition news to cash in on gains, and the "rescue survival" narrative is reinforcing doubts about the deal's true value. Analysts suggest that in the context of consecutive losses and revenue near the delisting line, a high-premium acquisition is more easily interpreted as a market capitalization management tool rather than genuine industrial transformation.
Regulators Keep a Watchful Eye
The May 2025 revisions to restructuring rules have made mergers and acquisitions easier, including a simplified review process for the first time, but scrutiny of high-premium acquisitions of unprofitable targets has not relaxed. The Shanghai Stock Exchange has repeatedly demanded detailed explanations of the valuation predictions in earnings-based assessments. Since 2025, multiple listed companies have been disciplined or investigated for misleading or hype-driven M&A. One notable case involved Sunflower Group, which announced a plan to acquire a company claiming a "custom manufacturing plus self-production" model. An investigation found that the target's factory was still under construction and it lacked independent production capacity, leading to fines totaling 5.1 million yuan against the company and its top executives.
The regulatory approach is clear: support standard-compliant companies pursuing acquisitions for genuine industrial upgrading, but explicitly oppose blind cross-industry bets and hot-topic chasing. In Vohringer's case, the exchange issued a supervisory work letter rather than a standard inquiry letter, targeting not just the company but also its directors, senior executives, and controlling shareholder.
For investors, this deal carries at least five distinct risks. First, there's the valuation bubble risk: an 80x PE for a small, low-tech equipment company raises serious questions about the price. If actual performance fails to match the valuation, goodwill impairment will swallow profits. Second, the profit promise is nearly impossible to achieve naturally, requiring a seven-fold increase in 2026 and a tripling of second-half profit. The revenue guarantee clause reveals this lack of confidence. Third, the company has no experience or talent in the PCB field, making the leap from wooden floors to circuit board equipment a massive challenge involving new customers and different market dynamics. Fourth, the core flooring business continues to deteriorate with negative margins and cash outflows, creating a risk of double losses if the acquisition fails. Fifth, the initial 214 million yuan cash outlay is significant, and the potential obligation to buy the remaining 49% stake would add further financial strain.
While the growth logic of PCB equipment in the AI supply chain is valid, equating industry momentum with a single company's ability to capitalize on it is the biggest cognitive trap in cross-industry M&A. For Vohringer, the real test lies not in the announcement but in the coming quarters' production output, customer certifications, and profit delivery. Investors must evaluate the company's response to regulatory inquiries and scrutinize the target's actual operational data before reaching any conclusions about the deal's true worth.
