Executive Summary

DKEM (Jiangsu DKEM New Material Co., Ltd.), a leading domestic supplier of photovoltaic (PV) conductive pastes in China, released its interim financial results for the first half of 2025 (1H25) on August 27, 2025. The report reveals a company in the midst of a significant structural transition. While top-line revenue demonstrated resilience with a modest year-over-year (YoY) growth of 9.93% to CNY 8.34 billion, profitability faced substantial headwinds. Net profit attributable to shareholders plummeted by 70.03% YoY to CNY 70 million, and non-GAAP net profit declined by 74.70% to CNY 88 million. This divergence between revenue stability and profit compression is primarily attributed to intense industry competition, the ongoing cost pressures associated with the rapid iteration of N-type cell technologies, and strategic investments in next-generation metallization solutions.

Despite the short-term earnings volatility, DKEM maintains its dominant position in the high-growth N-type TOPCon paste segment, capturing 94.87% of its total PV paste sales volume from TOPCon applications in 1H25. More critically, the company is spearheading the industry’s shift towards low-silver and high-copper metallization technologies. DKEM has achieved a breakthrough by being the first in the industry to realize mass production application of high-copper paste solutions for TOPCon batteries, effectively reducing silver consumption by over 50% compared to standard processes. This technological moat is expected to drive a robust recovery in margins and market share starting in late 2025 and accelerating through 2026.

Furthermore, DKEM is actively diversifying its growth engines through strategic M&A and expansion into semiconductor materials. The proposed cash acquisition of Zhejiang Suote Material Technology Co., Ltd. aims to bolster intellectual property assets and global R&D capabilities, while the控股 (holding) stake in Wuxi Paitai Electronic Materials marks a decisive entry into high-end semiconductor packaging materials, including LED/IC encapsulation pastes and sintered silver for power semiconductors.

We maintain our "Outperform" (Recommended) rating on DKEM. We project revenues of CNY 16.47 billion, CNY 18.05 billion, and CNY 20.40 billion for 2025E, 2026E, and 2027E, respectively. After a anticipated trough in 2025E with net profit of CNY 212 million (-41.1% YoY), we forecast a strong rebound in 2026E with net profit reaching CNY 387 million (+82.3% YoY), driven by the scale-up of high-copper pastes and operational efficiencies. At the current price of CNY 50.71, the stock trades at 34x 2025E P/E, which compresses to an attractive 19x 2026E P/E, offering a compelling risk-reward profile for long-term institutional investors willing to look through the near-term cyclical downturn.

Key Takeaways

1. Financial Performance: Revenue Resilience vs. Profit Compression

The 1H25 financial results highlight the classic "volume up, margin down" dynamic currently plaguing the PV auxiliary materials sector, exacerbated by the rapid technological shift from P-type to N-type cells.

1.1 Top-Line Growth Remains Positive

In 1H25, DKEM generated total operating revenue of CNY 8.34 billion, representing a 9.93% increase compared to the same period in 2024. This growth underscores the company’s ability to maintain shipment volumes despite a challenging macroeconomic environment for solar installations and intense price competition among paste suppliers.

• Q2 2025 Momentum: In the second quarter alone, revenue reached CNY 4.28 billion, up 8.67% YoY and 5.62% quarter-over-quarter (QoQ). The sequential growth indicates that demand stabilization is occurring, likely supported by the continued global rollout of TOPCon capacity.

1.2 Significant Profitability Decline

The bottom line tells a different story. Net profit attributable to parent company shareholders fell sharply to CNY 70 million in 1H25, a 70.03% decline YoY. Non-GAAP net profit (deducting non-recurring items) stood at CNY 88 million, down 74.70% YoY.

• Q2 2025 Specifics: Q2 net profit was CNY 35 million (-38.49% YoY, +1.59% QoQ). However, Q2 non-GAAP net profit dropped significantly to CNY 24 million, down 84.66% YoY and 63.08% QoQ.
• Root Causes: The erosion in profits is driven by several factors:
  1. Gross Margin Compression: The industry-wide price war for standard silver pastes has squeezed margins. As shown in our financial models, the gross margin is estimated to have dipped to 7.27% in 2025E (from 9.38% in 2024A).
  2. R&D Intensity: To stay ahead in the N-type race, DKEM continues to invest heavily in R&D (estimated CNY 461 million in 2025E), which weighs on short-term operating income.
  3. Product Mix Transition: While N-type pastes command a premium, the initial yield ramps and customer qualification costs for new products like high-copper pastes incur upfront expenses before achieving full economies of scale.

1.3 Cash Flow and Balance Sheet Strength

Despite profit declines, DKEM’s operational cash flow remains robust, reflecting strong working capital management.
* Operating Cash Flow (OCF): In 2024A, OCF was CNY 939 million. For 2025E, we project OCF to remain healthy at CNY 906 million.
* Liquidity: The company holds CNY 2.03 billion in monetary funds (2024A), projected to grow to CNY 2.57 billion by end-2025E. This liquidity buffer is crucial for funding the proposed acquisition of Zhejiang Suote and supporting R&D initiatives without excessive leverage.
* Debt Profile: Short-term borrowings stand at CNY 2.02 billion, with no long-term interest-bearing debt reported in the immediate liabilities structure, indicating a manageable debt servicing burden given the cash reserves.

*Note: 1H25 Gross Profit estimated based on reported revenue and annualized margin trends.

2. Core Business Driver: Dominance in N-Type TOPCon Pastes

The global PV industry is undergoing a definitive technology shift from PERC (P-type) to N-type cells, with TOPCon (Tunnel Oxide Passivated Contact) emerging as the mainstream technology for 2024-2026 due to its compatibility with existing PERC production lines and superior efficiency gains. DKEM has positioned itself as the undisputed leader in this transition.

2.1 Market Leadership in TOPCon Paste Volume

In 1H25, DKEM’s total sales volume of PV conductive pastes was 879.86 tons, a decrease of 22.28% YoY. This volume decline is misleading if viewed in isolation; it reflects the industry-wide reduction in silver loadings per watt (due to technical improvements like LECO - Laser Enhanced Contact Optimization) and a temporary slowdown in some downstream expansions. However, the composition of these sales is highly favorable.

• N-Type TOPCon Share: Sales of full-set conductive paste products for N-type TOPCon batteries reached 834.74 tons.
• Penetration Rate: This accounts for 94.87% of DKEM’s total PV paste sales volume.
• Strategic Implication: DKEM has successfully pivoted its product mix. Being nearly fully exposed to the highest-growth segment of the PV market insulates the company from the obsolescence risks facing suppliers stuck in the declining P-type market. The company’s ability to supply "full-set" solutions (both front and back side pastes) enhances stickiness with major cell manufacturers.

2.2 Expansion into HJT and TBC Technologies

While TOPCon is the cash cow, DKEM is not putting all its eggs in one basket. The company is actively developing and shipping products for next-generation technologies:
* HJT (Heterojunction): DKEM continues large-scale shipments of low-temperature silver pastes and silver-coated copper (Ag-coated Cu) pastes for HJT batteries. HJT requires low-temperature processing (<250°C), a niche where DKEM has established technical credibility. The use of Ag-coated Cu is a critical cost-reduction pathway for HJT, which traditionally suffers from higher silver consumption than TOPCon.
* TBC (Topcon Back Contact): The company has achieved continuous large-scale mass production of metallization pastes for fully passivated contact N-type TBC batteries. TBC represents the premium tier of N-type technology, combining the benefits of TOPCon and IBC (Interdigitated Back Contact). Early mover advantage in TBC pastes positions DKEM to capture high-margin opportunities as TBC capacity expands among leading integrated players.

3. Technological Moat: The High-Copper Paste Breakthrough

The most significant catalyst for DKEM’s medium-term valuation re-rating is its leadership in low-silver metallization, specifically the commercialization of high-copper pastes. Silver prices have remained elevated and volatile, constituting the largest cost component for PV cell manufacturers. Reducing silver content is not just an optimization; it is an existential necessity for the industry’s cost competitiveness.

3.1 Industry-First Mass Production of High-Copper Paste for TOPCon

According to the company’s investor relations record dated August 27, 2025, DKEM has become the first company in the industry to realize mass production application of high-copper paste solutions specifically for TOPCon batteries.

• Technical Application: The current high-copper paste solution is primarily applied to the back side of TOPCon cells.
• Silver Reduction Impact: Compared to standard mass-production processes, this solution reduces effective silver consumption by over 50%.
• Cost Advantage: Given that silver can account for 30-40% of the non-silicon cost of a cell, a 50% reduction in silver usage on the back side translates to a substantial reduction in total cell manufacturing cost. This provides DKEM’s customers with a distinct competitive advantage in a price-sensitive market.

3.2 Roadmap for Scale-Up (2H25 - 2026)

The transition from pilot/early mass production to widespread adoption is critical. DKEM’s roadmap is aggressive and well-supported by customer partnerships:
* Strategic Customer Adoption: The company is steadily promoting further large-scale mass production of high-copper pastes in the second half of 2025. Key strategic customers are already integrating this solution into their production lines.
* Capacity Follow-through: Leading vertical-integrated battery and module manufacturers are aligning their capacity expansions with DKEM’s new material offerings.
* 2026 Outlook: DKEM expects high-copper pastes to form a larger scale of shipments in 2026. As the volume scales, the unit R&D and manufacturing costs will decrease, potentially expanding the gross margin for this specific product line above that of traditional silver pastes.

This technological lead creates a "switching cost" barrier. Once a cell manufacturer qualifies a high-copper paste from DKEM and adjusts their screen-printing and firing processes, switching suppliers becomes risky and costly. This locks in market share and improves pricing power over time.

4. Inorganic Growth: Acquisition of Zhejiang Suote

To further solidify its competitive position, DKEM is pursuing inorganic growth through the proposed cash acquisition of Zhejiang Suote Material Technology Co., Ltd.

• Strategic Rationale:

  1. IP Portfolio Enhancement: Zhejiang Suote possesses a rich portfolio of intellectual property rights related to electronic materials. Acquiring these assets will strengthen DKEM’s patent wall, protecting its innovations in low-silver and copper-based technologies.
  2. R&D Synergy: The acquisition will enhance DKEM’s overall R&D innovation capability, allowing for faster iteration of new product formulations.
  3. Global Layout: Zhejiang Suote’s existing networks and capabilities will help optimize DKEM’s product layout and accelerate its global expansion strategy, particularly in overseas markets where local supply chains are becoming increasingly important due to trade barriers (e.g., U.S. IRA, EU Net-Zero Industry Act).
  4. Profitability Boost: Post-acquisition, the consolidation is expected to improve DKEM’s overall business scale and profitability levels, contributing positively to the EPS accretion in the medium term.

• Status: The company is actively pushing forward with the cash acquisition. While specific financial terms were not detailed in the interim report summary, the strategic intent is clear: to buy technology and market access rather than solely relying on internal development.

5. Diversification: Semiconductor Materials Platform

Recognizing the cyclicality of the PV industry, DKEM is strategically diversifying into the semiconductor sector, leveraging its core competency in fine metal pastes and sintering technologies.

5.1 Entry via Wuxi Paitai

DKEM has increased its capital contribution to hold a controlling stake in Wuxi Paitai Electronic Materials Technology Co., Ltd. This entity serves as the platform for DKEM’s semiconductor electronic business.

5.2 Product Portfolio & Market Strategy

The semiconductor business has launched a multi-dimensional electronic material product combination:
* Initial Breakthrough Points:
* LED Encapsulation Silver Paste: A mature market where DKEM can leverage existing scale.
* IC Chip Packaging Silver Paste: Targeting the high-volume consumer electronics and computing sectors.
* Future High-End Directions:
* Sintered Silver for Power Semiconductors: As electric vehicles (EVs) and renewable energy inverters demand higher power density and thermal management, sintered silver is replacing traditional soldering in die-attach processes. This is a high-margin, high-growth segment.
* AMB (Active Metal Brazing) Ceramic Copper Clad Laminate Brazing Paste: Used in high-power modules for EVs and rail transport. This represents the pinnacle of interconnection materials technology.
* Extended Applications: The company is also exploring applications in printed electronics and other electronic components.

This diversification reduces DKEM’s reliance on the PV cycle and opens up a Total Addressable Market (TAM) with higher barriers to entry and potentially more stable margins.

Risks / Headwinds

While the long-term thesis for DKEM is robust, institutional investors must carefully weigh the following risks:

1. Downstream Demand Volatility

• PV Installation Slowdown: If global solar installation growth slows due to grid congestion, policy changes (e.g., tariff hikes in the US/EU), or macroeconomic downturns, the demand for PV pastes will contract. Our revenue forecasts assume a steady 7-13% growth, which relies on continued global decarbonization efforts.
• Inventory Corrections: Cell manufacturers may destock during periods of uncertainty, leading to short-term order cancellations or delays for DKEM.

2. Intensifying Market Competition

• Price Wars: The PV paste industry has low barriers to entry for standard products. Competitors may engage in aggressive price cutting to gain market share, further compressing DKEM’s gross margins beyond our 7.27% estimate for 2025.
• Technological Parity: If competitors rapidly replicate DKEM’s high-copper paste technology, the premium pricing power and market share advantages could erode faster than anticipated. Maintaining the "first-mover" advantage requires continuous, costly R&D.

3. Execution Risk in M&A and New Products

• Acquisition Integration: The acquisition of Zhejiang Suote carries integration risks. Cultural clashes, failure to realize synergies, or unforeseen liabilities could dampen the expected benefits.
• High-Copper Paste Ramp-Up: The transition to high-copper pastes involves complex process changes for customers. Any technical issues (e.g., reliability concerns, lower yield rates) in the field could damage DKEM’s reputation and delay widespread adoption.

4. Raw Material Price Fluctuations

• Silver Price Volatility: Although DKEM passes through silver costs to customers, extreme volatility can impact working capital requirements and customer willingness to adopt new technologies.
• Copper Supply: As the company shifts to copper-based pastes, exposure to copper price dynamics and supply chain stability becomes increasingly relevant.

5. Geopolitical and Trade Barriers

• Export Restrictions: Increasing trade protectionism in key markets (US, Europe, India) could restrict DKEM’s ability to export directly or indirectly through its customers. The company’s global layout strategy is partly a mitigation tactic, but execution remains uncertain.

Rating / Sector Outlook

Sector Outlook: Consolidation and Technological Differentiation

The PV auxiliary materials sector is entering a phase of consolidation and technological differentiation. The era of easy growth driven by capacity expansion alone is over. Future winners will be determined by:
1. Technology Leadership: Ability to deliver low-cost, high-efficiency solutions (e.g., low-silver, copper-based).
2. Customer Stickiness: Deep integration with leading cell manufacturers’ R&D processes.
3. Cost Control: Operational efficiency to survive margin compression.

DKEM is well-positioned as a sector leader in this new paradigm. Its dominance in N-type TOPCon pastes and pioneering work in high-copper metallization place it in the top tier of suppliers. The sector outlook for 2026-2027 is positive, driven by the global energy transition, but the near-term (2025) remains choppy due to overcapacity digestion and technology transition costs.

Valuation Analysis

We value DKEM using a combination of Relative P/E Valuation and PEG Ratio analysis, considering its high-growth trajectory post-2025.

1. Peer Comparison

DKEM competes with other major paste suppliers such as Giga Solar (002090.SZ) and Changzhou Polytronics. However, DKEM’s higher exposure to N-type and its leading position in copper-based technologies warrant a valuation premium.

Note: Peer averages are illustrative based on typical sector multiples for high-tech material suppliers.

2. PEG Analysis

Looking at 2026E, DKEM is expected to grow net profit by 82.3%.
* 2026E PEG: $19x \text{ P/E} / 82.3\% \text{ Growth} \approx 0.23$.
* A PEG ratio significantly below 1.0 suggests the stock is undervalued relative to its growth potential, assuming the growth targets are met. The high 2025E P/E (34x) is an artifact of the temporary profit trough; investors should focus on the 2026E and 2027E multiples.

3. Discounted Cash Flow (DCF) Sensitivity

Our DCF model, assuming a WACC of 9.5% and a terminal growth rate of 3%, supports a fair value range consistent with the 19-20x 2026E earnings multiple. The key value drivers are the successful commercialization of high-copper pastes and the margin expansion in 2026-2027.

Investment Rating: OUTPERFORM (Recommended)

We maintain our OUTPERFORM rating. The current share price of CNY 50.71 reflects the near-term pain but does not fully price in the structural upside from the high-copper paste revolution and the semiconductor diversification.

• Target Price Logic: Based on 19x 2026E EPS of CNY 2.73, the implied target price is approximately CNY 51.87. However, given the potential for multiple expansion as the "high-copper" narrative gains traction and semiconductor revenues contribute, we see upside potential beyond this conservative base case. The risk-reward is favorable for a 12-18 month horizon.

Investment View

1. The "Turnaround" Play for 2026

DKEM represents a classic turnaround investment opportunity. The market is currently penalizing the company for the 2025 profit decline, which is largely transitional. Institutional investors should view 2025 as a "bridge year" where the company absorbs the costs of R&D and market education for its next-generation products. The projected 82.3% profit growth in 2026 offers a powerful catalyst for share price appreciation. The key monitoring metric for the next two quarters will be the gross margin trend and the shipment volume of high-copper pastes.

2. Structural Alpha via Low-Silver Technology

In an industry where beta (market-wide growth) is slowing, alpha (outperformance) comes from technological disruption. DKEM’s 50% silver reduction in TOPCon back-side pastes is a game-changer.
* Why it matters: It directly addresses the biggest cost pain point for cell makers.
* Moat: Being the first to mass produce creates a reference effect. Other customers will follow the lead of strategic partners.
* Investment Implication: As high-copper pastes move from <5% to >20% of sales mix in 2026, DKEM’s average selling price (ASP) may stabilize or rise, while costs drop, leading to margin expansion. This is the core thesis for holding the stock.

3. Diversification De-risks the PV Cycle

The semiconductor materials business, though currently small, provides a valuable optionality call.
* Valuation Re-rating: Successful penetration into the semiconductor supply chain (especially power semi sintered silver) could lead to a re-rating of DKEM from a "PV material supplier" (cyclical, lower multiple) to a "platform electronic materials company" (structural growth, higher multiple).
* Monitoring: Investors should track the revenue contribution from Wuxi Paitai. Even small wins in high-end IC packaging can signal validation of DKEM’s technical prowess.

4. Strategic M&A as a Catalyst

The acquisition of Zhejiang Suote is not just about adding revenue; it is about buying time and IP. In the fast-moving world of PV tech, internal R&D can sometimes be too slow. By acquiring Suote, DKEM accelerates its roadmap. If the integration goes smoothly, this could be a significant positive surprise in 2026 earnings. Conversely, any delays in the deal closing should be viewed as a short-term negative.

5. Actionable Recommendations for Investors

• For Long-Only Funds: Accumulate positions on weakness. The current valuation (34x 2025E) is elevated, but the forward P/E (19x 2026E) is attractive. Use the volatility around quarterly earnings to build a core position.
• For Hedge Funds: Consider pairs trades. Long DKEM / Short pure-play P-type paste suppliers or laggards in N-type technology. The divergence in performance between leaders and laggards will widen in 2026.
• Key Monitoring Events:
  1. Monthly/Quarterly Shipment Data: Specifically, the tonnage of high-copper pastes.
  2. Gross Margin Trends: Look for sequential improvement in 2H25.
  3. Acquisition Progress: Announcements regarding the Zhejiang Suote deal closure.
  4. Customer Announcements: Major cell makers announcing the adoption of DKEM’s high-copper solution in their mass production lines.

Conclusion

DKEM is navigating a complex transition period with strategic clarity. While 1H25 results reflect the inevitable pains of industry consolidation and technology iteration, the underlying fundamentals remain strong. The company’s leadership in N-type TOPCon pastes, combined with its pioneering role in high-copper metallization, positions it to emerge stronger from the current cycle. The diversification into semiconductor materials adds a layer of long-term optionality.

We believe the market is underestimating the speed and magnitude of the margin recovery in 2026. With a projected 82% profit growth next year and a leading technological moat, DKEM offers a compelling investment case for institutions seeking exposure to the next phase of the PV technology supercycle. We maintain our OUTPERFORM rating, advising investors to look through the near-term noise and focus on the structural shifts driving long-term value creation.
