**Canadian Solar Reports First Quarter 2026 Results and Announces <br> Appointment of Chief Executive Officer**

**Kitchener, Ontario, May 14, 2026** – <u>Canadian Solar Inc.</u> ("Canadian Solar" or the "Company") (NASDAQ: CSIQ) today announced financial results for the first quarter ended March 31, 2026.

**First Quarter Highlights**

· Solar
 module shipments of 2.5 GW, above guidance of 2.2 GW to 2.4 GW.

· Energy
 storage shipments of 2.1 GWh, exceeding guidance of 1.7 GWh to 1.9 GWh.

· Net
 revenues of $1.1 billion, at the high end of $900 million to $1.1 billion guidance.

· Gross
 margin of 25.1%.

· Commenced
 trial production at the flagship HJT solar cell factory in Jeffersonville, Indiana,
 marking a key milestone in U.S. domestic manufacturing, with commercial operation targeted
 to begin in July 2026.

· Appointment
 of Mr. Colin Parkin as Chief Executive Officer, effective May 14, 2026. Mr. Parkin
 previously served as President of Canadian Solar. Dr. Shawn Qu, the Company's
 founder, will transition from Chairman and Chief Executive Officer to the roles of Executive
 Chairman and Chief Technology Officer.

**Dr. Shawn Qu, Executive Chairman and CTO**, commented, "Canadian Solar's journey from its founding in Ontario to its current position as a global leader in integrated clean energy is a testament to our enduring resilience. We have consistently evolved, and today we are navigating a pivotal shift from volume-driven expansion to value-driven leadership. This evolution calls for thoughtful leadership succession, and I am incredibly proud to transition the Chief Executive role to Colin Parkin, whose execution and operational leadership have already established our first-mover advantage in the energy storage sector. As I dedicate my focus to advancing our technological roadmap, we are deepening our commitment to our U.S. manufacturing footprint. Our Jeffersonville solar cell facility has entered trial production, and commercial operation is expected to commence in about two months. Coupled with the capacity expansion at our Mesquite module plant, we are helping strengthen the American solar supply chain to ensure long-term, sustainable growth."

Dr. Shawn Qu founded Canadian Solar Inc. in Mississauga, Ontario 25 years ago. He holds a Ph.D. in Materials Science from the University of Toronto, an M.Sc. in Physics and an honorary doctorate from the University of Manitoba, and a B.Sc. in Physics from Tsinghua University. Dr. Qu has been a Fellow of the Canadian Academy of Engineering since 2019.

**Colin Parkin, CEO of Canadian Solar**, said, "We began the year with strong execution, exceeding guidance across all metrics. We delivered 2.5 GW of solar modules globally with an optimized mix of U.S. volumes. We maintained a disciplined approach to solar module shipments throughout the quarter, strategically managing volumes in response to elevated feedstock costs—including silver—to protect profitability. Our domestic manufacturing in the U.S. contributed robust margins, as we continue to reshore our supply chain. In our energy storage segment, we recognized revenue on 2.1 GWh of volume, supported by smooth construction progress across multiple customer sites. We will build on this momentum, with storage volumes expected to reach record levels in the second half. The broader solar market remains complex, as incremental price increases have not yet fully absorbed upstream cost pressures. Furthermore, competition in the storage sector is intensifying. In the face of these challenges, we remain committed to a balanced strategy focused on rigorous execution and continuous innovation."

**Ismael Guerrero, CEO of Canadian Solar's subsidiary Recurrent Energy**, said, "The sequential improvement in revenue was primarily driven by the sale of the Fort Duncan project, while the improvement in margin reflected the absence of pipeline impairment charges this quarter. As we continue to monetize other operating and under-construction assets, the impact on our results of operations may be less favorable in the near term. However, this strategy remains necessary to deleverage our balance sheet and recycle capital."

**Xinbo Zhu, Senior VP and CFO**, added, "In the first quarter of 2026, we achieved $1.1 billion in revenue and a gross margin of 25.1%, with gross margin increasing both sequentially and year-over-year primarily due to the recognition of tariff refund benefits. Aided by this one-time benefit and continued controls on operating expenses, net loss attributable to shareholders narrowed to $32 million, or $0.71 per share. We closed the period with a cash position of $1.9 billion."

**First Quarter 2026 Results**

Total solar module shipments recognized as revenue in Q1 2026 were 2.5 GW, down 42% quarter-over-quarter ("qoq") and down 64% year-over-year ("yoy").

Total battery energy storage shipments recognized as revenue in Q1 2026 were 2.1 GWh, up 5% qoq and up 142% yoy.

Net revenues were $1.1 billion in Q1 2026, down 11% sequentially and 10% yoy, mainly due to lower sales of solar modules partially offset by higher sales of battery energy storage systems.

Gross profit was $271 million, inclusive of a $93 million tariff refund benefit, compared to $124 million in Q4 2025 and $140 million in Q1 2025. Gross margin was 25.1%, compared to 10.2% and 11.7% in Q4 2025 and Q1 2025, respectively. The sequential and yoy increase in gross margin was primarily due to the recognition of IEEPA tariff refund benefits.

Operating expenses were $198 million, compared to $188 million in Q4 2025 and up from $195 million in Q1 2025 due to lower logistics costs offset by the absence of one-time gains recorded in the previous quarter. Operating expenses represented 18.4% of revenue, compared to 15.5% in Q4 2025 and 16.3% in Q1 2025.

Net loss attributable to Canadian Solar in accordance with generally accepted accounting principles in the United States of America ("GAAP") in Q1 2026 was $32 million, or a net loss of $0.71 per share, compared to a net loss of $86 million, or a net loss of $1.66 per share, in Q4 2025, and a net loss of $34 million, or a net loss of $0.69 per share, in Q1 2025. Net income or loss per diluted share includes the dilutive effect of convertible bonds, as applicable, and dividends on the Recurrent Energy redeemable preferred shares.

Net cash flow used in operating activities in Q1 2026 was $209 million, driven by changes in working capital, specifically an increase in inventories, compared to net cash flow used in operating activities of $65 million in Q4 2025 and net cash flow used in operating activities of $264 million in Q1 2025.

Total debt, including financing liabilities, was $6.8 billion as of March 31, 2026, including $3.8 billion, $2.6 billion and $0.4 billion related to Recurrent Energy, Manufacturing, and convertible notes, respectively. Total debt increased from $6.5 billion as of December 31, 2025, mainly due to the issuance of convertible notes. Total non-recourse debt under Recurrent Energy as of March 31, 2026, was $2.3 billion.

**Business Segments**

On December 1, 2025, Canadian Solar announced a strategic initiative to resume direct oversight of its U.S. operations. The Company has formed a new joint venture with its majority-owned subsidiary, CSI Solar Co., Ltd. ("CSI Solar"), by holding a 75.1% controlling stake in CS PowerTech Inc. ("CS PowerTech"), which operates U.S.-based manufacturing and sales of solar modules, solar cells, and advanced energy storage systems.

Following the consummation of this strategic initiative, Canadian Solar's business is organized into two segments:

· Manufacturing,
 comprising CS PowerTech, which focuses on the manufacturing and sales of solar products,
 battery energy storage products, and other power technology products for the U.S. market,
 and CSI Solar, which serves all other global markets; and

· Recurrent
 Energy, which focuses on solar power and battery storage project development, asset sales,
 power services, and electricity revenue from its operating portfolio.

**Manufacturing**

*<u>Solar Modules and Solar System Kits</u>*

The Company shipped 2.5 GW of solar modules and solar system kits to more than 60 countries and regions in Q1 2026.

Consistent with the Company's transition from volume-driven growth to high-value creation, the Company will focus its disclosure on strategic markets rather than aggregate global manufacturing capacity.

In the U.S., the Company operates a 5 GWp solar module factory in Mesquite, Texas, which it expects to expand to nameplate capacity of 10 GWp by the second half of 2026.

**Page 2**

The Company is also continuing to advance its flagship, state-of-the-art heterojunction technology ("HJT") solar cell factory in Jeffersonville, Indiana. In response to strong customer demand, the Company is increasing its production capacity beyond 5 GWp, with additional production lines being installed and commissioned through 2026.

&nbsp;&nbsp;&nbsp;&nbsp;· Phase
 I: Trial production began in April 2026. Phase I has a nameplate capacity of 2.1 GWp
 and is expected to become one of the first commercial-scale HJT solar cell facilities in
 the U.S. upon commencement of commercial operations.

&nbsp;&nbsp;&nbsp;&nbsp;· Phase
 II: The Company expects to begin trial production for Phase II at the beginning of 2027.
 This expansion will add 4.2 GWp of capacity, bringing the Company's total solar cell
 nameplate capacity in the U.S. to 6.3 GWp.

*<u>e-STORAGE: Battery Energy Storage Solutions</u>*

As of May 8, 2026, e-STORAGE contracted backlog, including contracted long-term service agreements, stood at $3.5 billion. These signed orders represent binding customer commitments and provide significant earnings visibility over a multi-year period.

**Recurrent Energy**

As of March 31, 2026, the Company had a total global solar project development pipeline of approximately 24 GWp and a battery energy storage project development pipeline of 81 GWh.

The business model consists of three key drivers:

· **Electricity revenue from the operating portfolio** to drive stable, diversified cash flows in growth
 markets with stable currencies;

· **Asset sales**, including selective operating assets in stable currency markets and assets in
 the rest of the world, to manage cash flow, debt levels and to fund growth in the operating
 portfolio; and

· **Power services (O&M)** through long-term operations and maintenance ("O&M")
 contracts, currently with 15 GW of contracted projects, to drive stable and long-term recurring
 earnings and synergies with the project development platform.

*<u>Project Development Pipeline – Solar</u>*

As of March 31, 2026, the Company's total solar project development pipeline was 23.7 GWp, including 1.8 GWp under construction, 2.6 GWp of backlog, and 19.3 GWp of projects in advanced and early-stage development, defined as follows:

&nbsp;&nbsp;&nbsp;&nbsp;· **Backlog projects** are late-stage projects that have passed their risk cliff date and are expected
 to start construction within the next one to four years. A project's risk cliff date
 is the date on which it passes the last high-risk development stage and varies by country.
 Typically, this occurs after the project has received all required environmental and regulatory
 approvals, and entered into interconnection agreements and offtake contracts, including feed-in
 tariff ("FIT") arrangements and power purchase agreements ("PPAs").
 A significant majority of backlog projects are contracted (i.e., have secured a PPA or FIT),
 and the remainder have reasonable assurance of securing PPAs.

&nbsp;&nbsp;&nbsp;&nbsp;· **Advanced pipeline projects** are mid-stage projects that have secured or are assessed by the Company
 as having a greater than 90% likelihood of securing an interconnection agreement.

&nbsp;&nbsp;&nbsp;&nbsp;· **Early-stage pipeline projects** are early-stage projects controlled by the Company that are in the
 process of securing interconnection.

While the magnitude of the Company's project development pipeline is an important indicator of potential increases in power generation and battery energy storage capacity, as well as potential future revenue growth, the development of projects in its pipeline is inherently uncertain. If the Company does not successfully complete the pipeline projects in a timely manner, it may not realize the anticipated benefits of those projects to the extent expected, which could adversely affect its business, results of operations, and financial condition. In addition, the Company's guidance and estimates of its future operating and financial results assume the completion of certain solar projects and battery energy storage projects in its pipeline. If the Company is unable to execute on its actionable pipeline, it may fail to meet its guidance, which could adversely affect the market price of its common shares and its business, results of operations, and financial condition.

**Business Outlook**

The Company's business outlook is based on management's current views and estimates, taking into account factors such as existing market conditions, order book, production capacity, input material prices, foreign exchange fluctuations, the anticipated timing of project sales, and the global economic environment. This outlook is subject to uncertainty with respect to, among other things, customer demand, project construction and sale schedules, product sales prices and costs, supply chain constraints, and geopolitical conflicts. Management's views and estimates are subject to change without notice.

In Q2 2026, the Company expects total revenue to be in the range of $1.0 billion to $1.2 billion. Gross margin is expected to be between 13% and 15%. Total module shipments recognized as revenue are expected to be in the range of 3.1 GW to 3.3 GW. Total battery energy storage shipments in Q2 2026 are expected to be in the range of 2.8 GWh to 3.2 GWh, including approximately 400 MWh to internal and external projects under execution.

The Company is reiterating its guidance of 6.5 to 7.0 GW of solar modules and 4.5 to 5.5 GWh of battery energy storage solutions for the U.S. market in 2026.

**Colin Parkin, CEO of Canadian Solar**, commented, "The first half of the year reflects prevailing market challenges, with solar margins remaining under pressure. In our energy storage business, margins are normalizing, and we remain partially exposed to fluctuations in lithium carbonate pricing. These factors, combined with a broader backdrop of policy uncertainty and geopolitical volatility, continue to impact both customers' long-term planning and our own operational execution. We anticipate stronger storage volumes and the benefits from the ramp-up of our U.S. domestic solar cell manufacturing to be weighted toward the second half, while our project development business continues to execute on its rebalancing strategy."
