Quarter (Q2 FY22) and First Half of Fiscal 2022 ended

September 30, 2021 (H1 FY22)

November 17, 2021: ReNew Energy Global plc (“ReNew Power”), India’s leading renewable energy company, today announced its consolidated results for the Q2 FY22 and H1 FY22.

Operating Highlights:

Key Operating Metrics

As of September 30, 2021, our portfolio consisted of 10,217 MWs compared to 9,958 MWs on September 30, 2020. As of September 30, 2021, commissioned capacity was 6,315 MW of which 3,653 MWs were wind, 2,563 MWs were solar and 99 MWs were hydro. We commissioned 63 MWs of wind and 451 MWs of solar capacity during Q2 FY22 against 0 MWs of wind and 10 MWs of solar in Q2 FY21. We commissioned 63 MWs of wind and 556 MWs of solar capacity during the H1 FY22 against 0 MWs of wind and 10 MWs of solar in H1 FY21.

Electricity sold

Total electricity sold for H1 FY22 was 7,558 million kWh, an increase of 1,385 million kWh, or 22.4%, over H1 FY21. Total electricity sold for Q2 FY22 was 4,003 million kWh, an increase of 969 million kWh or 31.9%, over Q2 FY21.

Electricity sold for H1 FY22 for wind assets was 5,304 million kWh, an increase of 1,317 million kWh, or 33.0%, over H1 FY21. Electricity sold for H1 FY22 for solar assets was 2,184 million kWh, a decrease of 2 million kWh or 0.1%, over H1 FY21 due to lower radiation levels than the prior year. Electricity sold for H1 FY22 for hydro assets was 70 million kWh. The hydro assets were acquired in the month of August 2021.

Electricity sold for Q2 FY22 for wind assets was 2,888 million kWh, an increase of 846 million kWh or 41.5%, over Q2 FY21. Electricity sold for Q2 FY22 for solar assets was 1,045 million kWh, an increase of 53 million kWh or 5.3%, over Q2 FY21. Electricity sold for Q2 FY22 for hydro assets was 70 million kWh. The hydro assets were acquired in the month of August 2021.

Plant Load Factor

Our weighted average Plant Load Factor (“PLF”) for H1 FY22 for wind assets was 33.6%, compared to 27.8%, for H1 FY21 due to an improvement in wind resource. The PLF for solar assets H1 FY22 was 22.6% compared to 22.8% for H1 FY21.

Our weighted average PLF for Q2 FY22 for wind assets was 36.3%, compared to 28.1% for Q2 FY21. The PLF for solar assets for Q2 FY22 was 20.4% compared to 20.6% for Q2 FY21.

Total Income

Total Income H1 FY22 was INR 38,119 million (US $ 514 million), an increase of 26.0% over H1 FY21. Total Income for Q2 FY22 was INR 21,312 million (US$ 287 million), an increase of 44.3% over Q2 FY21. The increase in total income was driven primarily due to increase in capacity and higher wind PLFs due to improved wind resource. Total income includes Finance Income of INR 807 million (US $ 11 million) for H1 FY22 and INR 343 million (US $ 5 million) for Q2 FY22.

Employee Benefit Expenses

Employee benefits expense for H1 FY22 was INR 2,282 million (US$ 31 million), an increase of 279.8% over H1 FY21. Employee benefit expenses for Q2 FY22 was INR 1,689 million (US$ 23 million), an increase of 480.1% over Q2 FY21. The increase is primarily due to an increase in the number of employees, as well as share based payment expense and others of INR 1,380 million (US$ 19 million).

Other Expenses

Other Expenses, which includes Operating & Maintenance (O&M) as well as General & Administrative (G&A), for H1 FY22 was INR 4,317 million (US$ 58 million), an increase of 21.9 % over H1 FY21. Other expenses for Q2 FY22 was INR 2,217 million (US$ 30 million), an increase of 20.3% over Q2 FY21. The increase was in line with the company’s expectations and was primarily driven by an increase in MWs capacity operating, MW hours generated, and certain investments for future growth. The increase was broadly in line with the increase in Total Income.

Net Loss

The net loss for H1 FY22 was INR 9,849 million (US$ 133 million) compared to a net loss of INR 592 million in H1 FY21. The net loss for H1 FY22 included INR 16,407 million (US$ 221 million) of charges related to listing on Nasdaq Stock Market LLC, issuance of share warrants, listing related share based payments and others.

Adjusted EBITDA ⁽²⁾

Adjusted EBITDA (Non-IFRS) for H1 FY22 was INR 31,902 million (US$ 430 million), an increase of 27.9% over H1 FY21. Adjusted EBITDA for Q2 FY22 was INR 18,184 million (US$ 245 million), an increase of 50.3% over Q2 FY21. Adjusted EBITDA was not adjusted for the net negative impact of weather relative to normal of approximately INR 2,966 million (US $40 million) for H1 FY22 and approximately INR 1,632 million (US$ 22 million) for Q2 FY22.

Portfolio Adjusted EBITDA Run Rate as of November 15, 2021

Portfolio Adjusted EBITDA Run Rate is an estimation of the Adjusted EBITDA once capacity is operating for a full year.

Note: Construction (including land acquisition) typically takes approximately six to 18 months for utility-scale wind energy projects, and four to 12 months for utility-scale solar energy projects. PPAs are typically signed three to six months after receipt of the LOA although there have been recent delays in receiving PPAs principally due to COVID-19.

Finance Costs

Finance costs for H1 FY22 was INR 18,163 million (US$ 245 million), a decrease of 2.4% over H1 FY21. Finance costs for Q2 FY22 was INR 8,878 million (US$ 120 million), a decrease of 3.7% over Q2 FY21. Finance costs include onetime cost of INR 855 million (US$ 12 million) on account of fair valuation of share warrants issued. The decrease in the finance costs after adjusting this onetime cost would be 7.0% and 13.0% respectively for H1 and Q2 FY22. The savings is primarily due to refinancing of high-cost borrowings with low-cost borrowings resulting in lowering of the weighted average rate of interest.

Cash Flow

Cash flow from operating activities for H1 FY22 was INR 13,882 million (US$ 187 million), compared to H1 FY21 at INR 12,710 million. The increase is on account of higher capacity and total income. Cash flow from operating activities for Q2 FY22 was INR 7,252 million (US$ 98 million), compared to INR 7,459 million, for Q2 FY21. The variance is primarily on account of increase in working capital.

Cash used in investing activities for H1 FY22 was INR 76,059 million (US$ 1,026 million), compared to an inflow of INR 2,232 million for H1 FY21, primarily due to increased capital expenditure on organic growth and an acquisition. Cash used in investing activities for Q2 FY22 was INR 48,374 million (US$ 652 million), compared to an inflow of INR 246 million for Q2 FY21, primarily due to capital expenditure for capacity addition and an acquisition.

Cash flow from financing activities for H1 FY22 was INR 67,865 million (US$ 915 million), compared to cash used in financing activity of INR 15,962 million in H1 FY21, primarily due to net equity raised and additional net borrowings to finance business growth. Cash flow from financing activities for Q2 FY22 was INR 60,959 million (US$ 822 million), compared to cash used in financing activity of INR 10,669 million in Q2 FY21, primarily due to net equity capital raised and additional net borrowings to finance business growth.

Cap Ex

During H1 FY22, we commissioned 618 MWs of projects for which our capex was INR 27,443 million (US $ 370 million) which has been broadly in line with the initially estimated cost.

Liquidity Position

As of September 30, 2021, we had INR 75,013 million (US$ 1,012 million) of cash and bank balances. This is aggregate of cash and cash equivalent INR 26,367 million (US$ 356 million) as per cash flow statement and INR 48,646 million (US$ 656 million) as bank balances other than cash and cash equivalent.

Receivables

Total Receivables as on September 30, 2021 was INR 52,699 million (US $ 711 million) of which INR 5,997 million (US $ 81 million) is unbilled and INR 7,351 million (US $ 99 million) is not due and others. Andhra Pradesh DISCOM (Distribution Companies being our customers) had a total outstanding of INR 16,749 million (US $ 226 million) which we expect to recover fully.

Cash flows for DISCOMs are likely to improve following the recovery of power demand which, in turn, would improve our collections. Going forward, we also anticipate that our DSOs will improve as a greater percentage of our revenues come from central government agencies such as Solar Energy Corporation of India.

Other updates

ESG

We released our first sustainability report on September 15, 2021 which reflects on our ESG performance for FY21. The report was prepared in line with the Global Reporting Initiative’s (GRI) sustainability reporting standards and was assured by DNV GL Business Assurance India Private Limited. By generating power through clean energy, we believe that we have helped the power sector avoid 1.1% of its greenhouse gases emissions. Our avoided emissions were more than 200 times that of its scope 1 & 2 emissions for the financial year 2020-21. We have been critically monitoring our water footprint and has saved over 66,000 kilolitres of water by deploying robotic dry cleaning of solar panels.

We have received the Great Place to Work recognition twice and has been recognized among the best employers in India in the category this past year by Great Place to Work. FORBES. Financial contributions towards energy access, water conservation, COVID-19 relief, women empowerment, and community development helped over 400,000 people across 200+ villages in nine states.

Acquisitions:

We completed the acquisition of 99 MWs of hydro assets on August 30, 2021 and the acquisition of 260 MWs of solar assets in the state of Telangana on November 4, 2021.

Guidance for FY22

Our estimate remains at 8.2 GWs of capacity operating by the end of FY22 and Adjusted EBITDA for FY22, excluding the impact of weather, will be approximately INR 60,750 million (or US$810 million using a foreign exchange rate of Indian rupees into U.S. dollars of INR 75.00 to US$1.00).

Use of Non-IFRS Financial Measures

Adjusted EBITDA

Adjusted EBITDA is a non- IFRS financial measure. We present Adjusted EBITDA as a supplemental measure of its performance. This measurement is not recognized in accordance with IFRS and should not be viewed as an alternative to IFRS measures of performance. The presentation of Adjusted EBITDA should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

We define Adjusted EBITDA as loss (income) plus (a) income tax expense, (b) finance costs, (c) depreciation and amortization, (d) share in loss of jointly controlled entities, (e) charges and impairments, such as listing expenses share based payment expense and others related to listing, less (f) finance income. We believe Adjusted EBITDA is useful to investors in assessing our ongoing financial performance and provides improved comparability on a like to like basis between periods through the exclusion of certain items that management believes are not indicative of our operational profitability and that may obscure underlying business results and trends. However, this measure should not be considered in isolation or viewed as a substitute for net income or other measures of performance determined in accordance with IFRS. Moreover, Adjusted EBITDA as used herein is not necessarily comparable to other similarly titled measures of other companies due to potential inconsistencies in the methods of calculation.

Our management believes this measure is useful to compare general operating performance from period to period and to make certain related management decisions. Adjusted EBITDA is also used by securities analysts, lenders and others in their evaluation of different companies because it excludes certain items that can vary widely across different industries or among companies within the same industry. For example, interest expense can be highly dependent on our capital structure, debt levels and credit ratings. Therefore, the impact of interest expense on earnings can vary significantly among companies. In addition, the tax positions of companies can vary because of their differing abilities to take advantage of tax benefits and because of the tax policies of the various jurisdictions in which they operate. As a result, effective tax rates and tax expense can vary considerably among companies.

Adjusted EBITDA has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under IFRS. Some of these limitations include:

Investors are encouraged to evaluate each adjustment and the reasons we consider it appropriate for supplemental analysis. For more information, please see the Reconciliations of Net loss to Adjusted EBITDA towards the end of this earnings release.

Cash Flow to Equity (CFe)

CEe is a Non-IFRS financial measure. We present CFe as a supplemental measure of our performance. This measurement is not recognized in accordance with IFRS and should not be viewed as an alternative to IFRS measures of performance. The presentation of CFe should not be construed as an inference that our future results will be unaffected by unusual or non-recurring items.

We define CFe as EBITDA add non cash expense, less interest expense paid, tax paid/(refund) and normalized loan repayments. Normalized loan repayments are repayment of scheduled payments as per the loan agreement. Adhoc payments and refinancing are not included in normalized loan repayments. The definition also excludes changes in net working capital and investing activities.

We believe IFRS metrics, such as net income (loss) and cash from operating activities, do not provide the same level of visibility into the performance and prospects of our operating business as a result of the long term capital-intensive nature of our businesses, non-cash depreciation and amortization, cash used for debt servicing as well as investments and costs related to the growth of our business.

Our business owns high-value, long-lived assets capable of generating substantial Cash Flows to Equity over time.

We believe that external consumers of our financial statements, including investors and research analysts, use CFe both to assess ReNew Power’s performance and as an indicator of its success in generating an attractive risk-adjusted total return, assess the value of the business and the platform. This has been a widely used metric by analysts to value our business, and hence we believe this will better help potential investors in analysing the cash generation from our operating assets.

We have disclosed CFe for our operational assets on a consolidated basis, which is not our cash from operations on a consolidated basis. We believe CFe supplements IFRS results to provide a more complete understanding of the financial and operating performance of our businesses than would not otherwise be achieved using IFRS results alone. CFe should be used as a supplemental measure and not in lieu of our financial results reported under IFRS.

Exhibit 99.3

ReNew Power Announces Results for the Second Quarter (Q2 FY22)

and First Half of Fiscal 2022, both ended September 30, 2021 (H1 FY22)

LONDON, Nov. 17, 2021: ReNew Energy Global plc (“ReNew Power”), India’s leading renewable energy company, today announced its consolidated results for the Q2 FY22 and H1 FY22.

Operating Highlights:

Portfolio Adjusted EBITDA Run Rate as of November 15, 2021

As of November 15, 2021, 7.0 GWs of capacity was commissioned. The chart below provides the Portfolio Adjusted EBITDA Run Rate which is an estimation of the Adjusted EBITDA once capacity is operating for a full year.

Note: Construction (including land acquisition) typically takes approximately six to 18 months for utility-scale wind energy projects, and four to 12 months for utility-scale solar energy projects. PPAs are typically signed three to six months after receipt of the LOA although there have been recent delays in receiving PPAs principally due to COVID-19.

Guidance for FY22

Our estimate remains at 8.2 GWs of capacity operating by the end of FY22 and Adjusted EBITDA for FY22, excluding the impact of weather, will be approximately INR 60,750 million (or US$810 million using a foreign exchange rate of Indian rupees into U.S. dollars of INR 75.00 to US$1.00).

Form 6-K containing financial statements and discussion of financial results has been filed with the SEC and can be accessed at www.sec.gov.

Webcast and Conference Call Information

A conference call has been scheduled to discuss these earnings results at 8:30 a.m. Eastern Time on November 18, 2021.
