We ended the quarter with a total cash position of $2.0 billion and reduced our leverage from a net debt to EBITDA standpoint. Overall,we remain disciplined in our capital deployment and are positioned to capture long-term growth and value."

Fourth Quarter 2022 Results

Total module shipments recognized as revenues in the fourth quarterof 2022 were 6.4 GW,up 68% yoy. Of the total,216 MWwere shippedto the Company's own utility-scale solar power projects.

Net revenues in the fourth quarter of 2022 were up 29% yoy and 2%quarter-over-quarter ("qoq") to $1.97 billion. The sequential increase primarily reflects higher solar module shipment volumes,partially offset by a small decline in module average selling price ("ASP") and lower revenue from battery storage solutions and project sales. The yoy increase was mainly driven by the significant increase in solar module shipments.

Gross profit in the fourth quarter of 2022 was $349 million,up 16% yoy and down 4% qoq. Gross margin in the fourth quarter of 2022 was 17.7%,compared to 18.8% in the third quarter of 2022,at the high end of the guidance range. The gross margin decline was mainly driven by lower margin contribution from project sales and lower module ASPs,partially offset by lower manufacturing costs and the depreciation of the Renminbi relative to the U.S. Dollar.

Total operating expenses in the fourth quarter of 2022 were $213 million compared to$274 million in the third quarter of 2022 and $234 million in the fourthquarter of 2021.Thedecrease was mainly driven by lower logistics costs and a lower impairment charge related to certain manufacturing assets.

Depreciation and amortization charges in the fourth quarter of 2022 were $50 million,compared to $56 million in the third quarter of 2022 and $84 million in the fourth quarter of 2021. The decline was mainly driven by an accelerated depreciation of a production facility that occurred in the fourth quarter of 2021 and currency translation of the Renminbi relative to the U.S. Dollar.

Net interest expense in the fourth quarter of 2022 was $11 million,compared to net interest income of $4 million in the third quarter of 2022 and net interest expense of $13 million in the fourth quarter of 2021. Net interest expense returned to a normalized level in the fourth quarter with the absence of an interest benefit generated by the anti-dumping and countervailing duty deposit refunds in the third quarter of 2022.

Net foreign exchange and derivative loss in the fourth quarter of 2022 was $15 million,compared to a net gain of $39 million in thethirdquarter of 2022 and a net gain of $1 million in the fourth quarter of 2021. The net foreign exchange loss was mainly driven by the strengthening of the Euro and the Japanese Yen against the U.S. Dollar.

Net income attributable to Canadian Solar in the fourth quarter of 2022 was $78 million,or $1.11 per diluted share ("diluted EPS"),compared to net income of $78 million,or $1.12 per diluted share,in the third quarter of 2022,and net income of $26 million,or $0.39 per diluted share,in the fourth quarter of 2021.

Net cash flow provided by operating activities in the fourth quarter of 2022 was $397 million,compared to $68 million in the third quarter of 2022. The increase in operating cash inflow was mainly driven by changes in working capital.

Total debt was $2,593 million as of December 31,2022,compared to $2,713 million as of September 30,and included $684 million and $842 million of debt related to project assets as of December 31,2022 and September 30,respectively. Non-recourse debt used to finance solar power systems and project assets increasedto $365 million as of December 31,from $311million as of September 30,2022.

Total project assets at the end of the fourth quarter of 2022 were$824 million,compared to$911million at the end of the third quarter of 2022. Project assets are projects that are developed and built for sale,as part of Global Energy's business model.

The net value of solar power systems at the end of the fourth quarter of 2022 were$365 million,compared to$101million at the end of the third quarter of 2022. Solar power systems are projects that are developed and built to hold on the Company's balance sheet. During the fourth quarter of 2022,the Company determined that certain solar projects in Brazil and Italy with book value of $264 millionwere appropriately reclassified as solar power systems as the intention on these projects transitioned to be held on the Company's balance sheet for the purpose of generating long-term electricity income.

Corporate Structure

The Company has two business segments: Global Energy and CSI Solar,which operate as follows:

The Global Energy segment carries out the Company's global project development activities for both solar and battery storage project development,which include sourcing land,interconnection agreements,structuring power purchase agreements (PPAs) and other permits and requirements. The Global Energy segment develops both stand-alone solar and stand-alone battery storage projects,as well as hybrid solar plus storage projects. Its monetization strategies vary between develop-to-sell,build-to-sell,and build-to-own,depending on business strategies and market conditions,with the goal of maximizing returns,accelerating cash turn,and minimizing capital risk.

The CSI Solar segment consists of solar module manufacturing and total system solutions,including inverters,solar system kits and EPC (engineering,procurement,and construction) services. The CSI Solar segment also includes the Company's battery storage system integration business,delivering bankable,end-to-end,turnkey battery storage solutions for utility-scale,commercial and industrial,and residential applications. These storage systems solutions are complemented with long-term service agreements,including future battery capacity augmentation services.

Global Energy Segment

Canadian Solar has one of the world's largest and most geographically diversified utility-scale solar and energy storage project development platforms,with a strong track record of originating,developing,financing,and building nearly 9 GWp of solar power plants and 3 GWh of battery storage power plants across six continents. As of January 2023,the Company had a total global solar pipeline of 25 GWp and an energy storage project development pipeline of 47 GWh.

The continued pipeline expansion and strong project development track record support Global Energy's growth in three key areas:

Project sales: The Company plans to grow its volume of project sales by a compound annual growth rate of approximately 20% to 2026,while holding and accumulating assets through investment vehicles (see below) in order to better capture asset value.

Investment vehicles: The Company is optimizing its project monetization strategy by establishing local investment vehicles to help maximize the value of its project assets while retaining minority ownership in these vehicles. This approach will help the Company build and grow a stable base of long-term cash flows from contracted electricity while recycling a large portion of the capital into developing new solar projects for growth. Meanwhile,the Company expects to capture additional operational value throughout the partial ownership period,including long-term cash flows from power sales,operations and maintenance ("O&M") and other services (see point 3). The Company currently owns a 15% stake in the Canadian Solar Infrastructure Fund ("CSIF",TSE: 9284),the largest Japanese infrastructure fund listed on the Tokyo Stock Exchange,and has established the CSFS Fund I,a fund of a similar nature in Italy.

Services: The Company currently manages over 3.7 GW of operational projects under long-term O&M agreements,and an additional 2.3 GW of contracted projects that will be operated and maintained by the Company once they are placed in operation. The Company's target is to reach 20 GW of projects under O&M agreements by 2026.

Project Development Pipeline – Solar

As of January 31,the Company's total solar project development pipeline was 24.7 GWp,including 1.8 GWp under construction,4.9 GWp of backlog,and 18.0 GWp of projects in advanced and early-stage pipelines,defined as follows:

Backlogprojects are late-stage projects that have passed their risk cliff date and are expected to start construction in the next 1-4 years. A project's risk cliff date is the date on which the project passes the last high-risk development stage and varies depending on the country where it is located. This is usually after the projects have received all the required environmental and regulatory approvals,and entered into interconnection agreements,feed-in tariff ("FIT") arrangements and power purchase agreements ("PPAs"). Over 90% of projects in backlog are contracted (i.e.,have secured a PPA or FIT),and the remaining are reasonably assured of securing PPAs.

Advanced pipeline projects are mid-stage projects that have secured or have more than 90% certainty of securing an interconnection agreement.

Early-stage pipeline projectsare early-stage projects controlled by Canadian Solar that are in the process of securing interconnection.
