Exhibit 99.1

March 28, 2024

Dear Shareholders,

We closed 2023 with $104.7 million revenue, 22.2% gross margin and a $9.3 million net loss. These results were below our full-year guidance primarily due to delays in closing the sales of six projects in U.S. and Europe, which are now expected to be pushed out to 2024. Our Q4 results were further impacted by several one-time items, including a $4.1 million adjustment to the earnout revenue at our 75 MW of projects in Poland as well as $5.0 million of write-offs of project cancellations and bad debt reserves.

Our projects continued to face delays due to a mix of rising interest rates affecting financing terms, utility-scale project delays stemming from transmission capacity challenges, and regulatory uncertainty in the U.S. and Europe. These challenges underscore the need for adaptability in our project financing strategies, the importance of early engagement with transmission and utility stakeholders, and close monitoring of regulatory developments in the U.S. and Europe. Despite these challenges, we are focused on executing our core solar project development strategy, diversifying our global footprint and advancing our position as a leading global renewable energy company.

Q4 highlights included:

We acknowledge the results over the past two years have been unsatisfactory and we fully accept responsibility for not meeting investor expectations. To address this,

Looking Forward

Looking forward to 2024 and beyond, we remain well positioned in the world's fastest growing solar markets that are benefiting from increasing demand for clean energy and supportive government policies and technology trends.

The solar industry is experiencing strong tailwinds, driven by the global commitment to renewable energy and sustainability. Governments and corporations worldwide are setting ambitious targets for reducing carbon emissions, which in turn fuels significant demand for solar energy solutions.

One of the most exciting developments in the renewable energy sector is the booming demand for solar power to support artificial intelligence (AI) operations. As AI technologies become increasingly integrated into our daily lives and business operations, the substantial energy needed to power these advanced systems is evident. Solar energy and battery storage, with their scalability and decreasing cost profile, are becoming a reliable source of power for these high-tech applications, further driving demand in the sector. Moreover, we are witnessing a surge in overall electricity and storage demand. The electrification of transportation, the proliferation of electric vehicles (EVs), and the increasing need for energy storage solutions are amplifying this demand.

With strong demand for solar and energy storage projects globally, we entered 2024 with around 3.1 GW of high quality advanced-stage project pipeline. We anticipate monetizing approximately 400 MW to 450 MW in 2024. Furthermore, we accumulated approximately 5 GW with 4 to 8 hours duration in the planning, which equals 20 to 40 GWh of independent storage project pipeline at the end of 2023. We expect to begin accelerating monetization in 2024.

We expect 2024 full year revenue to be in the range of $150 million - $160 million. We expect gross margin to be approximately 30% and net income to be at least $26 million, or approximately $0.50 per ADS. We anticipate our 2024 IPP revenue to be between $24 million - $26 million and gross margin to be approximately 50%. We expect gross profit contributed by DSA globally to be at least $6 million. For the first half of 2024, we expect revenue to be in the range of $50 million - $55 million. We expect gross margin to be approximately 30%. Finally, we expect our operating cash flow to be positive throughout the full year of 2024 and cash balance to exceed $100 million at the end of 2024.

In conclusion, the future of solar energy is extremely promising, and we are positioned to fully capitalize on the accelerating adoption of solar technology across the globe. With our exceptional expertise in developing and operating solar projects, extensive network of industry partnerships, and strong financial position, we are making great strides towards our goal of becoming a top global solar company. We are thrilled about the bright future of solar energy and are excited to be at the forefront of this incredible transformation towards a more sustainable future. With that overview, we will now review the details of our fourth quarter and full year financial performance.

Growing IPP Asset Portfolio in Attractive PPA Regions

As of December 31, we owned and operated IPP assets comprising 245 MW of solar PV projects and 15 MWh of storage.

In 2023, we monetized approximately 144 MW solar projects, over 670 MW BESS projects under DSA, and an additional 15 MWh BESS as IPP assets in China.

Q4 2023 Financial Results:

All figures refer to the fourth quarter of 2023, unless stated otherwise.

Revenue

Revenue of $44.0 million increased 71% year-over-year from Q4 2022 and 215% sequentially from Q3 2023. Revenue was lower than our guidance primarily due to delays in closing the sales of 6 projects in the U.S. and Europe, which are now expected to close in the first half of 2024.

Gross Profit and Gross Margin

Gross profit was $3.3 million, compared to $5.7 million in Q3 2023 and $6.0 million in Q4 2022. Gross margin was 7.6%, compared to 40.8% in Q3 2023 and 23.3% in Q4 2022. The gross margin was lower than expected, primarily attributable to a higher mix of EPC project revenue, as well as the previously mentioned project delays.

Operating Expense

Operating expenses were $9.5 million, lower than $9.6 million in Q3 2023 and higher than $7.2 million in Q4 2022. Our Q4 operating expenses were impacted by $5.0 million of write-offs of project cancellations and bad debt reserves, partially offset by savings from our cost reduction initiatives.

Net loss attributable to Emeren Group Ltd’s common shareholders

Net loss attributed to Emeren Group Ltd’s common shareholders was $8.1 million, compared to net loss of $9.4 million in Q3 2023 and net loss of $1.7 million in Q4 2022. Diluted net loss attributable to Emeren Group Ltd’s common shareholders per American Depositary Share (“ADS”) was $0.15, compared to diluted net loss of $0.17 in Q3 2023 and diluted net loss of $0.03 in Q4 2022.

Cash Flow

Cash provided by operating activities was $2.9 million; cash provided by investing activities was $7.0 million, and cash used in financing activities was $4.9 million.

Financial Position

Cash and cash equivalents at the end of Q4 2023 were $70.2 million compared to $59.2 million in Q3 2023.

Net asset value (NAV) is approximately $5.91 per ADS.

Our debt-to-asset ratio at the end of Q4 2023 was 9.44% compared to 9.93% in Q3 2023.

Shares Buyback

We purchased approximately $3.4 million ADS during the quarter and plan to continue to execute on the share buyback program, which has approximately $7.6 million remaining in authorization.

In addition, in February 2024, we announced that our Board of Directors approved an accelerated stock repurchase (ASR) program of up to $10 million, of which we have repurchased approximately 2.8 million ADS as of March 27, 2024.

Conclusion

In conclusion, despite the increasing global uncertainty, we maintain our confidence in the long-term growth of the solar industry, driven by increasing demand for clean energy. Our confidence is further strengthened by major technology trends such as AI and the growing demand for EVs. Given our leading industry position, we are well positioned to benefit from our substantial solar development and storage pipeline. With our expertise in solar project development, strong industry network, and solid balance sheet, we are making significant progress towards becoming an industry leading global solar and storage developer. Our focus remains on delivering value to our shareholders.

We extend our heartfelt thanks to our committed employees, loyal customers, reliable partners, and supportive shareholders. Your steadfast dedication is pivotal to the success of Emeren Group Ltd, and together, we look forward to shaping a sustainable future.

Use of Non-GAAP Financial Measures

To supplement Emeren Group Ltd’s financial statements presented on a US GAAP basis, Emeren Group Ltd provides non-GAAP financial data as supplemental measures of its performance.

To provide investors with additional insight and allow for a more comprehensive understanding of the information used by management in its financial and decision-making surrounding pro-forma operations, we supplement our consolidated financial statements presented on a basis consistent with U.S. generally accepted accounting principles, or GAAP, with EBITDA, Adjusted EBITDA as non-GAAP financial measures of earnings.

• EBITDA represents net income before income tax expense (benefit), interest expense, depreciation and amortization.

• Adjusted EBITDA represents EBITDA plus discount of electricity subsidy in China, plus share-based compensation, plus impairment of long-lived assets, plus loss/(gain) on disposal of assets, plus foreign exchange loss/(gain).

Our management uses EBITDA, Adjusted EBITDA as financial measures to evaluate the profitability and efficiency of our business model. We use these non-GAAP financial measures to access the strength of the underlying operations of our business. These adjustments, and the non-GAAP financial measures that are derived from them, provide supplemental information to analyze our operations between periods and over time.

We find these measures especially useful when reviewing pro-forma results of operations, which include large non-cash impairment of long-lived assets and loss on disposal of assets. Investors should consider our non-GAAP financial measures in addition to, and not as a substitute for, financial measures prepared in accordance with GAAP.
