Core Viewpoint - Jiangsu Jianyuan Construction Co., Ltd. (referred to as "Jianyuan") is the only IPO candidate in the civil engineering and construction industry accepted by the Beijing Stock Exchange for 2024, but its IPO review has been stagnant for over 8 months since submitting the second round of responses in March 2025, raising concerns about its ongoing operational capabilities due to various compliance issues [1][13]. Group 1: Revenue Recognition Issues - Jianyuan's revenue recognition practices have come under scrutiny, with over 90% of its business using the output method based on progress to recognize revenue, which, while compliant with accounting standards, allows for some manipulation [2][14]. - The company admitted that from 2021 to 2023, its quarterly revenue was based on "estimated confirmations," leading to questions about the accuracy and verifiability of its financial data prior to 2024 [3][15]. - In 2022-2024 and the first half of 2025, the proportion of revenue covered by customer or supervisory confirmations increased from 60.67% to 86.81%, yet nearly 40% of revenue in the previous three years lacked external confirmation [5][17]. Group 2: Accounts Receivable and Bad Debt Provisions - Jianyuan's accounts receivable and contract assets have been significant, with total amounts of 980 million, 1.103 billion, 1.336 billion, and 1.333 billion yuan for 2022-2024 and the first half of 2025, representing 81.53%, 77.90%, 90.21%, and 167.67% of its revenue, respectively [7][18]. - Some core clients have repayment cycles exceeding two years, and there are concerns about the adequacy of bad debt provisions, as evidenced by the treatment of clients classified as dishonest executors [8][18]. - The company has faced regulatory scrutiny regarding its accounting treatment of contract assets, which may lead to underestimating the aging of receivables and consequently lowering bad debt provisions [20]. Group 3: Research and Development Expenditure - Jianyuan's reported R&D expenditures were 44.09 million, 39.09 million, 51.01 million, and 25.89 million yuan for the respective periods, constituting 3.16%, 3.25%, 3.60%, and 3.26% of its revenue, but there are concerns about the accuracy of these figures due to misclassification of costs [10][21]. - The actual R&D expenses, after adjustments, were significantly lower, indicating a decline in the proportion of R&D costs relative to revenue [11][21]. - Regulatory authorities have raised questions about the qualifications of internally transitioned R&D personnel, emphasizing the need for detailed disclosures regarding their backgrounds and capabilities [12][22].
