EXECUTIVE SUMMARY / 研报摘要
Langsha Holdings, listed on the Shanghai Stock Exchange under ticker 600137.SH, is one of China's earliest publicly listed innerwear companies, known for its 'Langsha' brand of thermal underwear, shorts, and hosiery. In FY2025, the company reported revenue of approximately RMB 390 million (USD 53.92 million), a modest 2.65% year-over-year increase, while net income rose 38.11% to RMB 32.32 million (USD 4.47 million), driven largely by gross margin expansion of 4.53 percentage points to 24.92%. Despite this profitability improvement, the company remains a marginal player in a highly fragmented and intensely competitive market, ranking 43rd among listed peers in revenue and facing structural challenges including an over-reliance on OEM production (nearly 89% of output), extreme geographic concentration with over 90% of sales in East China, and a product mix heavily skewed toward low-margin shorts (nearly half of revenue). The company's AI and semiconductor exposure is effectively nil; management has stated it has not deployed AI tools such as DeepSeek and has no concrete roadmap for technology-driven transformation. The investment case rests primarily on a modest valuation, potential brand revitalization through celebrity endorsement and digital channel expansion, and a clean balance sheet with low leverage. However, weak competitive positioning, limited R&D intensity, and the absence of a credible second growth curve warrant a cautious, value-oriented assessment.
1. Company Overview
Sichuan Langsha Holding Co., Ltd. (ticker: 600137.SH) is a Shanghai Stock Exchange-listed company whose principal business is the manufacture and sale of knitted innerwear and fabrics, alongside wholesale, retail, and internet sales activities. The company was originally incorporated in 1998 and later listed through a reverse merger in 2006, becoming the first A-share company with innerwear as its core business. Its primary operating subsidiary is Zhejiang Langsha Innerwear Co., Ltd., which holds a 'High and New Technology Enterprise' designation. The company's product portfolio centers on thermal underwear (seamless and seamed), men's and women's shorts, fashion innerwear, and bras, complemented by外贸 (foreign trade) OEM processing services. As of the end of FY2025, the company operated 2 directly-operated stores, 267 dealer franchise outlets, and 5 OEM clients for export processing. The company is headquartered in Yibin, Sichuan Province, though its manufacturing and brand operations are primarily based in Zhejiang Province through its subsidiary.
The corporate structure reflects a controlling shareholder model: Langsha Holding Group Co., Ltd. holds approximately 43.89% of shares, with Tibet Julang Technology Co., Ltd. holding an additional 11.91%. The company's ticker symbol on the SSE is 600137, and it reports under the Textile and Apparel industry classification, with a sub-industry focus on innerwear and hosiery.
2. Business Model & Core Operations
Langsha operates a hybrid production model that combines a limited amount of self-manufacturing with a dominant reliance on OEM outsourcing. In FY2025, only 11.45% of total production volume was self-manufactured, while 88.55% was outsourced to external contractors. This 'asset-light' strategy was adopted to minimize fixed capital expenditure and enable rapid market response, but it has also been criticized for diluting brand control and product quality consistency. The product mix is notably concentrated: shorts (men's and women's) accounted for 49.25% of main business revenue, followed by innerwear at 29.33%, other categories at 15.42%, and bras at only 6.00%. This skew toward lower-value, commoditized shorts limits pricing power and brand differentiation.
Sales are conducted through a dual-channel structure. The company maintains a dealer-based distribution network for offline sales and operates online through e-commerce platforms including Tmall, JD.com, and Douyin. Since October 2024, the company has also launched self-operated livestreaming, which carries higher gross margins but incurs significant commission and traffic acquisition costs. The geographic footprint is overwhelmingly domestic, with export revenue accounting for only 2.13% of main business income in FY2025.
3. Market Position & Competition
The Chinese innerwear market is characterized by intense, fragmented competition with no single player holding dominant share. Langsha, despite its 'China Innerwear First Stock' legacy, has seen its market position erode significantly. In FY2025, the company's revenue of RMB 390 million ranked 43rd among listed peers in the apparel and home textile sector, far below the industry average of RMB 2.251 billion. Its net income ranking was somewhat better at 31st, but the absolute profit level remains modest.
The competitive landscape includes established national brands such as Aimer Lingerie, Cosmo Lady, and Embry Form, as well as a proliferation of regional and white-label players. Langsha's historical brand equity—built on decades of advertising and distribution reach—remains its primary asset, but brand relevance among younger demographics has weakened. The company has attempted to address this through a brand rejuvenation strategy, including the appointment of actor Ren Jialun as brand ambassador in September 2025 and the launch of limited-edition product lines. However, these marketing initiatives have yet to translate into sustained revenue acceleration.
4. AI & Semiconductor Alignment
Langsha has no meaningful exposure to the AI or semiconductor sectors. When directly queried by investors in March 2025 about whether the company had deployed DeepSeek or other AI tools, management responded that it had not yet done so but would 'consider deployment in the future'. No concrete timeline, budget, or application roadmap has been disclosed. The company's R&D and technology capabilities are focused entirely on textile-related工艺 improvements—fabric comfort, functional materials, and production process optimization—rather than on digital or AI-driven innovation.
The absence of AI alignment is not merely a disclosure gap; it reflects the company's fundamental business reality. Langsha is a traditional consumer goods manufacturer with limited capital resources (FY2025 R&D expenditure was RMB 11.75 million, or 3.01% of revenue) and no in-house software or data science capabilities. Any 'AI narrative' attached to the stock would be speculative and unsupported by operational substance. For investors seeking technology-sector exposure, Langsha offers no relevant proposition.
5. Customer & Regional Analysis
Langsha's revenue is exceptionally concentrated geographically. In FY2025, East China accounted for 89.76% of main business revenue, followed by Central-South China at 7.07% and Southwest China at just 0.48%. This concentration exposes the company to regional economic fluctuations and competitive dynamics in its core Zhejiang and surrounding markets. The near-absence of meaningful revenue from North, Northeast, and Southwest China suggests that the brand's distribution network has not achieved national penetration, particularly in lower-tier cities where growth potential may exist.
From a customer perspective, the company's shift toward online and livestreaming channels has begun to alter its revenue mix. Self-operated livestreaming, introduced in late 2024, offers higher gross margins but requires significant upfront investment in traffic acquisition. The dealer network, while extensive at 267 franchise outlets, has been shrinking from 325 outlets in 2023, indicating attrition in the traditional distribution channel. Export sales, though a negligible portion of revenue, provide some diversification and are conducted through five OEM clients.
6. Economic Moat Analysis
Langsha's economic moat is narrow and arguably eroding. The company's historical advantages—brand recognition and scale in hosiery production—have diminished as competition intensified and consumer preferences evolved. The 'Langsha' trademark remains a recognized name in Chinese innerwear, and the company operates one of the world's largest sock production facilities with an annual capacity of 1.2 billion pairs. However, this scale advantage is underutilized: with 88.55% of production outsourced, the company's own manufacturing footprint contributes only a small fraction of total output.
Switching costs for consumers are effectively zero in this category, and brand loyalty is weak. The company has no proprietary technology, no exclusive distribution agreements, and no cost advantage that cannot be replicated by competitors. The 'asset-light' OEM model, while capital-efficient, has been criticized for undermining quality control and brand integrity. In essence, Langsha competes primarily on brand heritage and price, neither of which constitutes a durable moat in a commoditized market.
7. Unique Competitive Advantages
Despite its challenges, Langsha retains several identifiable advantages. First, its brand heritage and 'China Famous Trademark' status provide residual consumer trust, particularly among older demographics in East China. Second, the company's balance sheet is conservatively managed: the debt-to-asset ratio stood at 23.52% at FY2025 year-end, and the current ratio of 3.93 indicates ample short-term liquidity. Third, the recent profitability improvement—gross margin up 4.53 percentage points to 24.92% and net margin up to 8.29%—suggests that product mix optimization and cost controls are yielding results.
Fourth, the company has demonstrated a willingness to modernize its marketing approach, including celebrity endorsements and livestreaming. The appointment of Ren Jialun and the launch of 'Jia Ren Limited Edition' products represent a more aggressive brand strategy than in previous years. Whether these efforts can reverse the long-term revenue stagnation remains uncertain, but they indicate that management recognizes the need for change.
8. R&D and Technological Capability
Langsha's R&D expenditure is modest in absolute terms but represents a reasonable proportion of revenue for a company of its size. In FY2025, R&D investment totaled RMB 11.75 million (USD 1.62 million), or 3.01% of revenue. This was a slight decline from the prior year. The company's R&D activities are focused on applied textile innovation: improving fabric comfort, developing functional materials (e.g., moisture-wicking, thermal regulation), and enhancing production processes.
The company's subsidiary, Zhejiang Langsha Innerwear Co., Ltd., holds High and New Technology Enterprise status, which provides tax benefits and validates a baseline level of technical capability. Langsha has also pursued collaboration with external research institutions and universities to supplement its internal capabilities. However, the company's technology position is best described as 'follower' rather than 'leader.' It does not drive industry-wide innovation in materials or design; instead, it adapts existing technologies to its product lines. For a company competing in a mature, low-growth category, this approach may be adequate for survival but is unlikely to generate breakthrough competitive advantage.
The Chinese innerwear market is large but structurally challenging. It is a fully competitive industry characterized by low barriers to entry, a proliferation of brands, and persistent 'disorderly competition' (无序竞争). The market exhibits divergent trends: consumers in lower-tier cities prioritize brand recognition and value-for-money, while those in Tier 1 and Tier 2 cities increasingly favor personalization and premiumization. This fragmentation makes it difficult for mid-market brands like Langsha to establish a clear positioning.
Macroeconomic factors compound the challenge. Domestic demand recovery has been slower than expected, and geopolitical tensions have added uncertainty to export markets. The 'guochao' (national trend) consumer movement presents an opportunity for domestic brands, but competition for that consumer cohort is intense. Industry-wide, textile and apparel companies are grappling with rising labor costs, inventory management pressures, and the need to invest in digital channels—all while operating in a low-margin environment. Langsha's revenue growth of 2.65% in FY2025, while positive, significantly lags the broader economy and suggests that the company is not gaining share in this competitive arena.
10. Investment Conclusion & Enterprise Quality
Langsha Holdings presents a classic 'value trap' profile. On the positive side, the company is profitable, generates positive operating cash flow (RMB 73.36 million in FY2025, up 410% year-over-year), maintains a clean balance sheet with low leverage, and trades at what may appear to be a modest valuation. The recent margin improvement and brand rejuvenation efforts offer some optionality for a turnaround.
However, the structural weaknesses are profound. Revenue has stagnated for years, the company is a marginal player in its industry, nearly 90% of production is outsourced with attendant quality risks, and the product mix is weighted toward commoditized categories. The absence of any AI or technology-related growth vector means the company cannot participate in the economy's most dynamic sectors. The geographic and channel concentration further limits growth potential.
Enterprise quality, assessed holistically, is below average. The company has survived for decades, which speaks to some degree of operational resilience, but it has not demonstrated the ability to grow profitably or build durable competitive advantages. Management's recent initiatives—brand ambassador partnerships, livestreaming, and cost controls—are sensible but incremental. They do not address the fundamental question of how a mid-market innerwear brand can thrive in a market that rewards either scale or differentiation, and Langsha possesses neither in sufficient measure.
For investors, Langsha is best understood as a low-beta, dividend-paying holding (the proposed FY2025 dividend is RMB 0.20 per share) rather than a growth story. Any investment thesis must rest on the expectation of a successful brand revitalization or a strategic pivot that has not yet materialized. Until such a catalyst emerges, the risk-reward profile remains unattractive relative to opportunities elsewhere in the consumer or technology sectors.
