Core Viewpoint - The logic of "volume" is more important than "price" in the current industry environment, indicating a shift in competitive dynamics within the vacuum cleaner market [4][28]. Industry Environment - The vacuum cleaner industry is undergoing significant changes since 2022, with increased competition and market saturation. From 2019 to 2022, the market share of the top three brands (CR3) increased, but is projected to decline from 67% to 62% in volume and from 76% to 69% in sales revenue from 2022 to 2024 [4][5]. Company Strategy - Stone Technology (688169.SH) has adopted a strategy of "exchanging price for volume," leading to increased revenue but declining profits. In the first half of 2024, the company reported a revenue of 7.903 billion, a 79% increase year-on-year, while net profit fell by 39.5% to 678 million [6][9]. Sales and Marketing Expenses - The increase in sales expenses is a significant factor, with the sales expense ratio reaching 24.84% in 2024 and further increasing to 27.39% in the first half of 2025. This reflects a shift towards brand building and market promotion, as well as a transition from a local distributor model to a direct sales model [9][11]. Market Position and Performance - Despite the competitive environment, Stone Technology has managed to increase its market share in China from 17% to 22% in sales volume and from 21% to 25% in sales revenue between 2022 and 2024. In the first half of 2025, these figures continued to rise [18][19]. Global Market Leadership - Stone Technology achieved a global market share of 16.0% in 2024, further increasing to 19.3% in the first quarter of 2025, solidifying its position as a global leader in the vacuum cleaner market [21][23]. Growth Dynamics - The shift from price-driven growth to volume-driven growth is evident, with sales volume increasing by 32.9% in 2024, while the average selling price saw minimal growth. This trend is mirrored in the performance of competitors like Ecovacs [24][25]. Brand Influence and New Product Lines - Stone Technology's brand influence has led to a significant increase in sales of its new product line, the floor washing machine, which achieved approximately 970 million in retail sales in the first half of 2025, marking a year-on-year increase of over 600% [35][36]. Market Potential - The penetration rate of vacuum cleaners in China remains low at 4.3%, indicating substantial growth potential. The market is expected to grow significantly as it approaches a balanced penetration rate of 20% [39][40]. Industry Growth Indicators - The vacuum cleaner market is still in a rapid growth phase, with retail sales volume reaching approximately 3.15 million units in the first half of 2025, a 40.7% year-on-year increase [41].
