I. Industry Where the Company Operated in the Reporting Period

1. Industry development

In recent years, the rapid advancement and refinement of photovoltaic technologies have led to significant progress and maturation in the mass production techniques for photovoltaic products. This evolution has resulted in steady enhancements in the performance of photovoltaic products, coupled with continuous reductions in production costs. As a result, the overall cost of photovoltaic power generation has consistently decreased, thereby bolstering the competitiveness of solar energy and laying a robust foundation for the ongoing development of the photovoltaic industry.

(1) Global photovoltaic newly installed capacity reached a new record high

Since the beginning of the 21st century, the photovoltaic industry has entered a stage of explosive growth. Influenced by factors such as the international economic situation, trade frictions, and technological iterations, the growth of global photovoltaic market slowed from 2011 to 2013. Nevertheless, overall, it remained on an upward trend. Since 2013, propelled by continuous advancements in industry technologies, the cost of photovoltaic power generation has steadily declined. Also, traditional photovoltaic markets have experienced a resurgence, while emerging photovoltaic markets such as South Asia, Southeast Asia, Australia, Latin America, and the Middle East have rapidly been seen. This has led to an accelerated development of the global photovoltaic industry, with the market scale continuously expanding.

According to the International Renewable Energy Agency (IRENA) in its World Energy Transition Outlook , under the 1.5°C temperature rise control scenario, the global installed capacity of renewable energy needs to surpass 11,000 GW by 2030. This means that solar and wind power generation are projected to contribute approximately 90% of the newly added renewable energy generation capacity. According to Bloomberg New Energy Finance (BNEF), the world’s newly installed PV capacity in 2023 reached 444 GW, marking a year-on-year increase of 76%, reaching a new high. In the context of green development across the world, the advancement of renewable energy sources, represented by photovoltaics, has become a global consensus. What is more, with photovoltaic power generation increasingly emerging as the most competitive source of electricity in many countries, it is anticipated that the global photovoltaic market will continue to experience rapid growth.

(2) The gigawatt-scale market continues to expand, with huge potential in emerging markets

The main markets for photovoltaic power generation currently center around China, the United States, Europe, India, and Brazil. However, as the cost of photovoltaic power generation rapidly decreases, emerging markets in Southeast Asia, Latin America, and the Middle East are planning gigawatt-scale photovoltaic projects. According to the SolarPower Europe (SPE) report, in 2023, a total of 32 countries and regions achieved gigawatt-scale photovoltaic installations, marking an increase of six from the previous year. Projections indicate that this number will rise to 39 in 2024 and 53 in 2025, showcasing the continuous emergence of new markets and their vast potential.

(3) The outlook for the global photovoltaic market is promising.

Since the Paris Agreement was executed, the global consensus has shifted towards the urgent pursuit of carbon neutrality and temperature control. Establishing an energy system primarily based on renewable energy is a crucial pathway towards carbon neutrality, presenting the photovoltaic industry with historic development opportunities. At the end of November 2023, during the 28th United Nations Climate Change Conference (COP28) held in Dubai, over 100 countries reached a significant agreement aimed to triple the global installed capacity of renewable energy by 2030, reaching at least 11 TW. According to the latest report from the International Renewable Energy Agency (IRENA) in 2023, titled World Energy Transition Outlook , in order to limit global warming to 1.5 degrees Celsius, the global cumulative installed capacity of photovoltaics is projected to reach at least 5.4 TW by 2030. This implies that from 2023 to 2030, the newly added installed capacity will exceed 4.3 TW, with an average annual growth of 544 GW.

Description on major factors for significant YoY changes  Applicable □ Not applicable

The significant year-on-year increase in net cash flows from operating activities is primarily attributed to the expansion of production and sales scales, leading to increased receipts, which outweigh the rise in procurement expenditure.
The significant year-on-year decrease in net cash flows from investing activities is primarily attributed to the increase in cash payments for long-term assets.
The significant year-on-year increase from financing activities is mainly attributed to convertible corporate bonds issued by the Company and a decrease in repayments in the year.

Market risk: Throughout the duration of exchange derivatives, revaluation gains or losses will accrue in each accounting period. Upon maturity or forward delivery of exchange derivatives, any disparity between the contracted exchange rate and the prevailing market rate on the delivery date will yield actual transaction gains or losses. These gains or losses will offset the cumulative revaluation gains or losses, resulting in investment gains or losses. Exchange derivative transactions are conducted with the principle of mitigating operational risks arising from exchange rate fluctuations and are not for speculative arbitrage trading. 2. Liquidity risk: Unreasonable purchases of foreign exchange derivatives can trigger liquidity risks. The trading scheme will be

risk, operational risk, and legal risk)	based on exchange assets and liabilities, with a rigorous review of import and export contracts. It will involve prudent planning of exchange funds and timely selection of exchange derivatives, including appropriate netting derivatives, to reduce the demand for cash flow at maturity and ensure sufficient funds for settlement at delivery. All exchange derivative transactions will be conducted on the premise of normal trade business backgrounds, with strengthened risk control over accounts receivable, and strict management of overdue receivables and bad debts. 3. Fulfillment risk: The selection of inappropriate trading schemes could potentially expose the Company to fulfillment risks relating to exchange derivatives. As such, the Company will assess financial institutions with strong creditworthiness and with which the Company has established long-term business relationships to mitigate any potential fulfillment risks. 4. Other risks: Unclear terms in exchange derivative contracts could potentially expose the Company to legal risk. The Company will prudentially examine contract terms agreed upon with partners and rigorously adhere to risk management protocols to mitigate legal risks.
The changes in prices or fair values of derivatives held in the reporting period, specific methods and the settings of relevant assumptions and parameters should be disclosed for the analysis of the fair values.	The Company’s derivative investments encompass, but are not limited to, forward exchange contracts (fixed-date and option period), options, and structured forward exchange contracts. Relevant parameters for fair value measurement are directly from the forward exchange contract rates provided by the principal banks.
Litigation (if applicable)	None

The disclosure date for the general meeting’s announcement for the approval of derivative investments (if any)	December 13, 2022
Special opinion of independent directors on the Company’s derivative investments and risk control	The Company’s involvement in exchange derivative trading primarily arises from the growing export business and such investments are largely settled in US dollars and euros. Due to the impact of international political and economic uncertainties, fluctuations in the exchange market are frequent. Conducting exchange derivative transactions allows the Company to mitigate exchange rate risks by locking in exchange rates. These transactions are conducted without speculative or arbitrage motives. The Company has implemented the Exchange Hedging Management Policy to regulate business operations and approval processes, thereby effectively managing the risks associated with derivative transactions. The review procedures for the exchange derivative transactions undertaken are in compliance with applicable laws, regulations, and normative guidelines. There are no instances that would jeopardize the interests of the Company or its shareholders, particularly those of minority shareholders.

Explanation of project delays and expected return shortfall and reason (including the reason for selecting “non-applicable” for “expected return realized or not”)	1. Supplementing working capital is not covered by the expected return data. 2.The project “5GW high-efficiency cell and 10GW module facilities, as well as supporting facilities” has not realized its expected return due to declining prices of cells and modules. 3. The project “pilot run for high-efficiency cell development” includes two pilot run lines. The installations, electricity supply and equipment commissioning for the first pilot run line have been completed in accordance with the technical agreement, and have been accepted. After the project adjustment, the installations, electricity supply and equipment commissioning for the second pilot run line have been completed with manufacturing processes being tested. Since the initiation of the “pilot run for high-efficiency cell development” by the Company, the pace of technological iteration in production equipment related to HJT solar cells in the photovoltaic industry has accelerated. To enhance the conversion efficiency of HJT technology and continually reduce production costs, enabling the high-efficiency cell technology to reach mass production levels sooner, the Company has adjusted the project’s process route and upgraded technical solutions to respond to the latest trends in HJT technology in the industry. Equipment suppliers have also made adjustments to equipment upgrades based on the requirements of this project. The extended delivery period and installation and commissioning timeframe for high-capacity equipment have resulted in an overall delay in

In 2024, according to PV Infolink, global demand for photovoltaic modules is expected to reach approximately 538GW under optimistic conditions. In line with this forecast, The Company will further cultivate its presence in global markets, with a target module shipment range of 85-95 GW.

(III) Potential risks

1. Risk from global industrial policies

The pace and quality of development in the photovoltaic industry are significantly influenced by global policies regarding the solar energy sector. On the domestic front, although the photovoltaic industry has entered a subsidy-free era, the introduction of new industrial policies concerning grid connection, energy storage deployment, and other aspects by the government could bring about uncertainties regarding the transformation and upgrading of the photovoltaic industry and the operations of photovoltaic companies in the domestic market. Internationally, the reinforced manufacturing reshoring in Europe and the United States is leading to a trend of regionalization in photovoltaic manufacturing. The dynamic adjustments of photovoltaic industry policies and updates to renewable energy development goals in countries worldwide will introduce uncertainties for photovoltaic companies operating in overseas markets.

Risk from international trade protectionism

Since 2022, a notable policy trend has emerged in countries and regions like Europe, the United States, and India, placing increasing emphasis on the development of their domestic photovoltaic industries. These nations are seeking to reshape the global photovoltaic industry supply chain through measures aimed at encouraging industrial reshoring. In March 2023, the EU unveiled the Net Zero Industry Act and the Critical Raw Materials Act , outlining restrictions on the sourcing countries and raw materials used in photovoltaic products. In addition to traditional trade barriers such as anti-dumping, anti-subsidy, and anti-evasion measures, new types of trade barriers based on carbon emissions, environment, human rights, and patents are gradually emerging, evolving, and intensifying. Examples include the EU’s proposed Carbon Border Adjustment Mechanism (CBAM), the U.S. Uyghur Forced Labor Prevention Act , and various forms of trade barriers such as the EU Regulation on Prohibiting Products Made with Forced Labor on the EU Market . The ongoing trade frictions in the photovoltaic sector will bring about negative impacts on the internationalization of PV companies.

Risk of supply chain stability

The photovoltaic industry spans multiple segments and relies on a diverse array of raw materials. The secure supply of each raw material is crucial, as any disruption could have profound effects on the entire industry. In recent years, various factors such as frequent unforeseen events, industrial policy restrictions, and fluctuations in prices of commodities like petroleum, precious metals, and basic metals have led to varying degrees of supply-demand imbalances for raw materials used in the industry, including polysilicon, film, glass, silver paste, solder strip, aluminum frames, back sheets, and quartz sand. Furthermore, due to the impact of international trade imbalances, global circulation of goods has faced significant restrictions, leading to considerable fluctuations in international logistics costs. Disruptions to the supply of photovoltaic raw materials and the stability of the global logistics system will pose risks to the supply chain security of photovoltaic companies.

Supply-demand imbalance risk

Since 2021, the rapid growth of the global market has not only driven capacity expansion within the industry but has also spurred leaders from other industries to enter the sector. According to the China Photovoltaic Industry Association, as of the end of 2023, domestic capacities for silicon wafers, cells, and modules have all exceeded 800GW, with production outputs reaching 622GW, 545GW, and 499GW respectively. These figures surpass the global newly added installed capacity. With the release of both capacity and production, there is a clear trend of cyclical and structural oversupply in the industry, leading to price declines across various segments of the photovoltaic value chain. According to statistics, as of the end of 2023, the winning bids of solar modules declined by over 40% compared to the beginning of the year to below 1 yuan/watt.

Risk from technology iteration

The photovoltaic industry is experiencing a period of rapid technological iteration, with next-generation cell and module technologies such as N-type TOPCon, HJT, and BC steadily increasing their market share. This poses significant challenges to the existing P-type capacity that has not yet been phased out or upgraded. Furthermore, there is a degree of competition among TOPCon, HJT, and BC technologies, along with the emergence and application of frontier technologies like perovskite, further adding to the perplexity faced by photovoltaic companies in their future technology choices.

Geopolitical risk

In recent years, a series of geopolitical upheavals such as the Russia-Ukraine conflict, the Israel-Palestine conflict, and the Red Sea crisis have brought about multifaceted impacts on market demand, transportation, financial settlements, and other aspects. These may pose challenges and operational risks to major photovoltaic companies deeply integrated into the global market.

Exchange rate risk

Full Text of the 2023 Annual Report of JA Solar Technology Co., Ltd.

As one of the flagship industries that “go global”, the photovoltaic sector boasts a significant portion of overseas operations among its leading companies. In overseas operations, foreign currency settlement remains predominant, and fluctuations in exchange rates directly impact the operation performance of internationalized companies. It is increasingly challenging to manage exchange rate risk due to adjustments to fiscal and monetary policies across countries, and changes in international trade landscape and environment. Failure to take effective measures may expose photovoltaic companies to negative impact caused by exchange rate volatility.
