CANADIAN SOLAR INC

Rating Action and Rationale

• EthiFinance Ratings downgrades Canadian Solar Inc´s long-term rating from BBB to BBB-, changing the outlook from Negative to Stable.
• The downgrade is mainly driven by a gradual weakening in the company’s financial profile over recent periods. It is critical to characterize the recent financial deterioration as cyclical rather than structural, primarily driven by a temporary global oversupply of modules. With price normalization and capacity rationalization in China already underway, and the company´s strategic transition to an IPP model supported by proven capital recycling mechanisms, including asset rotation, non-recourse structures, and tax equity, the financial snapshot from 2023–2025 is not representative of the company´s long-term risk profile. The gradual weakening has been materialized in higher leverage and tighter coverage ratios, with net debt-to-EBITDA and EBITDA-to-interest moving from historically solid levels (~2.4x and >8x, respectively) to current metrics that are expected to average around ~4x and ~5x going forward. This deterioration reflects both sector-specific headwinds in the electrical equipment / solar manufacturing segment (namely the steep decline in module pricing, oversupply across the value chain and higher cost pressures) which have compressed margins, and the company’s strategic transition within Recurrent Energy from a predominantly “develop-to-sell” approach toward a long-term ownership model (a hybrid IPP strategy).
• However, as announced in its Q3 2025 earnings call, the company now plans to accelerate asset rotation to strengthen cash flow and deleverage its balance sheet. While the strategic transition is viewed positively from a qualitative standpoint (given the increased revenue stability and lower earnings volatility associated with contracted cash flows under PPAs) it requires significant upfront capital expenditure, largely financed through debt or non-recourse structures that nevertheless carry meaningful financial commitments. As a result, the company’s consolidated leverage is expected to remain elevated, limiting deleveraging capacity in the near term. However, the company’s asset rotation plan during 2026 progressively enhances cash flow and support balance sheet strengthening as its effect begin to materialize.
• In addition, the Stable Outlook reflects our expectation that, despite leverage remaining elevated in the coming periods, the company will be able to keep its credit metrics within the ranges outlined above. We do not anticipate a further deterioration in the short to medium term, as the current business and financial trajectory is deemed broadly predictable and consistent with the rating category.
• The investment grade rating is underpinned by i) a sector with solid fundamentals (medium levels of profitability, controlled volatility, high barriers to entry and favorable growth prospects) which is further supported by the positive impact of ESG on its assessment; ii) the company’s strong competitive positioning based on its vertical integration, its appropriate size and an outstanding diversification, both by product and by geography, which significantly mitigates regulatory and market risk, and iii) a governance framework assessed positively, reflecting a high-quality management team and the transparency and discipline associated with a publicly listed ownership structure.
• On the other hand, the rating is constrained by i) a strategic shift by the Recurrent Energy segment that requires a significant amount of CapEx, mostly financed with debt, and therefore has led to a leverage increase and a coverage ratio deterioration; ii) the significant weighting of minority interests in the CSI Solar division (36%), which may dilute the cash transfer to the holding in the event of a dividend distribution to support the Recurrent Energy division, although these dividend policies are structured to maintain flexibility and support the group.
• According to our methodology, the renewable energy sector (capital goods – electrical equipment) is well aligned with ESG factors (heatmap score of between 1 and 2). This consideration results in a one-category upgrade (three notches) in the industry risk assessment. The group’s ESG policies are considered neutral (ESG score between 1.5 and 3.5), resulting in a rating that is not affected by these factors.

Fundamentals

Business Risk Profile

Industry Risk Assessment

• The renewable energy sector offers high growth prospects. The manufacturing of photovoltaic (PV) panels is subject to medium volatility, offers medium margins and rather high barriers to entry.

Canadian Solar's main activity is manufacturing, placing it within the "capital goods" sector for industry risk assessment. The capital goods sector is characterised by medium volatility, rather high barriers to entry (significant capex required to build up a plant) and a medium level of profitability (EBIT margin ~10%). In particular, the photovoltaic sector has increasingly strong growth prospects with a CAGR between 6.9% and 14% over the next 5 to 6 years. This growth will be underpinned by rising electricity demand and the increasing penetration of solar generation in the energy mix, driven by favourable policies and financial returns. The global PV sector is dominated by Chinese companies, which could be affected by geopolitical turmoil between China and the US.

Complementing its manufacturing base, Canadian Solar has vertically integrated downstream into the development, ownership, and operation of solar power projects, positioning this segment within the 'Utilities' sector. The Utilities sector is characterised by low to medium volatility, high barriers to entry due to complex regulatory approval, grid interconnection rights, high capital intensity and a stable, often recurring level of profitability (EBIT margin ~15-25%). Canadian Solar’s global presence and use of long-term contracted or hedged structures help mitigate regional regulatory risks inherent to this sector.

Unlike the manufacturing sector, the global Utility sector is fragmented and regional rather than dominated by a single country's output. However, players could be affected by regulatory changes, interest rate fluctuations, and grid capacity constraints, leading to curtailments. Consequently, the market is multi-local and regulation-dependent. In this context, Canadian Solar’s geographic and business-model diversification provides an additional layer of resilience relative to more regionally concentrated peers.

The long-term growth prospects for the solar and battery storage sector are exceptionally strong, driven by a global consensus on decarbonization and energy security. The industry is still in its early stages; in 2024, solar power accounted for only 7% of global electricity generation. To meet the 1.5°C Paris Agreement goal, global installed solar PV capacity is projected to grow from approximately 2.8 TW in 2025 to 18 TW by 2050, with storage expected to grow even faster due to increasing flexibility needs across major grids.

Beyond traditional utility and residential adoption, growth is being impulsed by new, large-scale electricity consumers. These include the massive energy needs for data centers powering artificial intelligence (AI) and the widespread electrification, including electric vehicles (EVs).

The industry's growth is increasingly tied to the hybrid "Solar + Energy Storage" model. Whereas solar's key weakness is its intermittency, battery energy storage systems (BESS) solve this by storing excess energy and dispatching it when demand is high or the sun is not shining.

Despite strong growth, the sector is characterized by medium volatility, which directly impacts profitability. The industry frequently experiences periods of oversupply of polysilicon, solar wafers, cells and modules. This oversupply creates substantial downward pressure on the prices for solar modules.

The sector's financial health also depends largely on the availability and size of government subsidy programs and economic incentives. Furthermore, the industry is highly exposed to geopolitical tensions and trade barriers, such as antidumping and countervailing duties and tariffs in key markets like the U.S. and Europe, which add significant costs and uncertainty. As a capital-intensive industry, the sector is also sensitive to interest rates. Higher rates increase financing costs for project development, which in return can exert downward pressure on the prices of solar systems as developers seek to maintain their internal rates of return.

The solar and battery storage sector has significant barriers to entry for new companies, particularly in manufacturing and large-scale project development. The most significant barrier is the high capital intensity. Manufacturing requires significant capital investments in manufacturing technology, facilities and capital equipment. The industry is also characterized by significant technological changes and frequent new product introductions, pressing companies to heavily invest in R&D to remain competitive.

• An industry that benefits from positive ESG impacts.

The renewable energy industry is well aligned with ESG factors (sector heatmap score between 1 and 2). This consideration results in a one category upgrade (three notches) in the industry risk assessment. The industry contributes to pollution reduction and biodiversity protection as a substitute for highly-polluting traditional energy sources. However, related construction emits GHG and uses significant resources. The impact on consumers and communities is positive as clean energy contributes to good health and economic development. The impact on suppliers is medium as China, where ESG issues may exist, is involved in much of the supply chain.

Competitive Positioning

• Canadian Solar has a strong competitive positioning among PV manufacturing companies, with two-segment business models, a globally diversified portfolio, significant vertical integration and leadership in next-generation technology.

Canadian Solar has established a strong competitive position as one of the world's largest and most established "Tier 1" solar technology companies. 

A key advantage is the company's diversified two-segment business model, which consists of CSI Solar and Recurrent Energy. The Recurrent Energy segment provides a stable channel for the company's own modules and battery storage solutions, securing demand even during market downturns. Conversely, the manufacturing expertise of CSI Solar gives the project development arm vertical integration with upstream manufacturing, allowing for better cost control and a reliable supply of high-quality components. This integrated approach allows the company to capture value across the solar energy chain.

This synergy is built on a foundation of massive manufacturing scale and vertical integration. Canadian Solar's flexible vertically integrated business model includes in-house capacity for solar ingots, wafers, cells, and modules, as well as battery energy storage systems. This integration provides significant flexibility to respond to short-term demand changes and allows for better control over manufacturing costs, which is a critical advantage in a market with volatile raw material prices like polysilicon. The company is also actively diversifying its manufacturing footprint globally, with new facilities in the U.S. (Texas, Indiana, Kentucky) to meet local content requirements under the U.S. IRA and mitigate geopolitical trade risks.

Canadian Solar operates as a globally diversified company, competing against a range of highly specialized and large-scale rivals. 

Sungrow Power Supply Co is a primary competitor in the battery energy storage and power electronics space. It does not compete in the solar module market, instead it is a highly specialized technology provider and a global leader in photovoltaic inverters, with overseas production capacity of 50GW as of 1H25. It is a direct competitor to Canadian Solar´s e-STORAGE business, with a planned advanced energy storage of 20GWh.

First Solar is a major US-based manufacturer. Its primary differentiator is its technology. First Solar produces solar modules based on alternative solar technologies, such as thin-film PV materials. This technology does not use silicon, making the company less susceptible to increases in the cost of this material. The company has set a target for annual US capacity in 2027 of 17.7GW in thin-fil modules, although thin film technology has very limited market share outside the U.S.

LONGi Green energy Technology Co. is one of the largest “China-based” companies in the solar industry and an intense competitor in the module manufacturing segment. It is a vertically integrated manufacturer, similar to Canadian Solar's CSI Solar arm, and competes directly in the production and sale of crystalline silicon solar modules. The production capacity is expected to reach 200GW, 100GW and 150GW respectively by 2026.

Canadian Solar's strategy appears to be built on three core pillars designed to navigate the sector's challenges: technological leadership, solid geographic positioning (especially in the U.S.), and well-built vertical-chain diversification, which together strengthen the company’s competitive resilience.

First, the company is focused on limiting technological obsolescence. After relying on PERC cell technology, Canadian Solar began a significant upgrade to N-type and TOPCon technology, starting mass production of TOPCon modules in early 2023. This move aligns with the industry's upgrade to this new technology, which offers higher conversion efficiency, better performance in hot temperatures, and less power degradation over the module's lifespan.

Second, the company is executing a major strategic pivot to the U.S. market. The Americas accounted for 51.8% of its revenue in 2024, making it its largest market. Historically, the company's manufacturing has been concentrated in China and Southeast Asia, which are subject to U.S. tariffs and antidumping/countervailing duties (AD/CVD). To mitigate these trade risks and capitalize on favorable "Made in USA" incentives under the Inflation Reduction Act (IRA), Canadian Solar is investing heavily in a U.S. manufacturing footprint, which should meaningfully enhance its access to the U.S. utility-scale market and improve margin visibility through IRA tax credits.

Third, the company is executing a diversification strategy both vertically and into recurring revenue streams. It has aggressively expanded its e-STORAGE (BESS) business and is now vertically integrating further into BESS and battery cell manufacturing, targeting capacities 15 GWh and 3 GWh, respectively, by year-end 2025. Simultaneously, its Recurrent Energy segment is transitioning from a "develop-to-sell" model to a "hybrid model", retaining ownership of key projects in the U.S. and Europe to generate stable and predictable revenues as an Independent Power Producer (IPP). 

• Globally distributed diversification, with a major impulse of US manufacturing during 2024. Moderate concentration of the customer base and notably clustered supply chain.

Canadian Solar maintains a high degree of geographical diversification across its sales, manufacturing, and project development operations. This global footprint is a core strategy to mitigate regional market volatility and complex geopolitical trade risks.

The company's geographical revenue has changed its balance during the last three years. In 2024, the Americas were the largest market, accounting for 51.8% of net revenues (a significant increase from 34.4% in 2023), followed by Asia at 30.0% (down from 41.0%), and Europe and other regions at 18.2% (down from 24.6%).
