Core Viewpoint - The company, Qicheng Biotechnology, has faced significant challenges leading to the termination of its IPO review, primarily due to declining financial performance and concerns regarding its construction projects and compliance issues [1][4][16]. Group 1: Market Position - Qicheng Biotechnology is a leading player in the hydrolyzed tannin industry, holding a global market share of approximately 7.12% in the tannic acid market and 9.07% in the gallic acid market as of 2023, indicating strong competitive positioning [2][3][24]. - The global market size for tannic acid and gallic acid in 2023 was approximately 1.16 billion and 1.91 billion respectively, highlighting the industry's growth potential [2]. Group 2: Financial Performance - The company's revenue has shown a downward trend, with reported figures of 359.76 million, 291.13 million, and 312.38 million for the years 2021 to 2023, respectively, and a projected decline in 2024 [4][17]. - The net profit attributable to shareholders decreased from 52.91 million in 2021 to 39.40 million in 2022, and slightly increased to 40.37 million in 2023, but is expected to drop to 29.85 million in 2024 [4][17]. - The company anticipates a further decline in revenue and net profit for the first quarter of 2025, with expected decreases of 2.94%-10.84% in revenue and 40.33%-48.86% in net profit [5][17]. Group 3: Construction Projects and Compliance Issues - Significant investments in construction projects, such as the Qicheng Biotechnology Industrial Park, have not yet been capitalized, raising concerns about the authenticity and reasonableness of these expenditures [9][10]. - The company has faced scrutiny for not completing necessary construction permits and for starting projects without proper approvals, although local authorities have indicated that these issues are not severe enough to warrant penalties [11][12][14][15]. - The company has been subject to multiple administrative penalties from various regulatory bodies, indicating ongoing compliance challenges [11][12]. Group 4: Market Dynamics and Competitive Landscape - The company has experienced fluctuations in revenue from its industrial tannic acid product, primarily due to changes in customer procurement strategies and market competition [21]. - The demand for mixed feed additives containing tannic acid has declined significantly, with utilization rates dropping to 7.17% and 9.17% in 2023 and 2024, respectively, largely due to the financial struggles of key customers [22]. - The competitive landscape is characterized by price reductions in response to increased market pressure, which has affected the company's profit margins [24].
