Core Viewpoint - Shanghai Sunmi Technology Group Co., Ltd. has submitted a main board IPO application to the Hong Kong Stock Exchange, despite concerns over its heavy reliance on hardware sales, customer attrition, and weak profit margins from its OEM model [1][7]. Group 1: Financial Performance - The company's revenue from 2022 to 2024 shows a "V-shaped" growth trend, with figures of 3.404 billion yuan, 3.071 billion yuan, and 3.456 billion yuan respectively, while net profits were 160 million yuan, 101 million yuan, and 181 million yuan [2][8]. - Hardware sales account for over 99.5% of total revenue for three consecutive years, while software service revenue peaked at only 2% in 2023 and is projected to drop to 0.5% in 2024, indicating a lack of diversification in revenue streams [2][8]. - The gross margin for 2024 is expected to recover to 28.9%, but it remains below the industry leaders' range of 35%-40%, with a net profit margin of only 5.2% in 2024, further declining to 2.5% in the first three quarters of 2025 [2][8]. Group 2: Customer Base and Risks - The total number of customers has decreased from 2,506 in 2022 to 2,262 in 2024, reflecting a nearly 10% attrition rate over three years, with the top five customers contributing 41.1% of revenue in 2024 [3][9]. - A significant challenge arises from a legal dispute with the largest customer in Brazil, which has filed for arbitration claiming 354 million USD (approximately 2.55 billion yuan), equivalent to 73.8% of the company's total revenue for 2024 [3][9]. Group 3: Supply Chain and Production Model - The company relies heavily on OEM production, with 96.7% of its manufacturing outsourced, leaving only 3.3% produced in-house, which constrains profit margins [4][10]. - The top five suppliers account for 66.3% of procurement, and reliance on single-source components poses a risk of supply chain disruptions [4][10]. - The company plans to build a factory in Mexico to mitigate geopolitical risks, but it remains exposed to policy uncertainties until the factory is operational in 2026 [4][10]. Group 4: IPO and Future Outlook - The IPO is seen as a critical move for the company, which previously withdrew its application for the Sci-Tech Innovation Board due to concerns over its gross margin and other issues [4][10]. - The company aims to address its hardware dependency and customer concentration risks through a strategy of "hardware export + software enhancement," with approximately 35% of the IPO proceeds allocated for BIOT research and development [4][10]. - The competitive landscape is intensifying, with rivals achieving gross margins of 35.2%, and the company must increase its software revenue share to over 5% within 12 months post-IPO to maintain its growth narrative [4][10].
