ReNew (RNW) Q4 2026 earnings review
Manufacturing Drives Top-Line Growth, But Surging Costs Crush Q4 Bottom Line
ReNew’s Q4 FY26 Total Income grew 15% YoY to INR 39.5 billion, propelled by strong execution in capacity expansion and external sales from its solar manufacturing arm. However, the top-line beat failed to reach the bottom line. Q4 Net Profit reversed sharply, collapsing 75% YoY to INR 777 million. The culprit was a severe contraction in operating leverage caused by surging finance costs (+9% YoY for Q4, +18% for the full year) and a 48% spike in Q4 depreciation associated with newly commissioned projects. Despite the weak Q4 bottom line, full-year FY26 results were stable, and management's FY27 guidance projects continued EBITDA expansion, anchored by an increasingly vital manufacturing business.
🐂 Bull Case
The solar cell and module business is a confirmed growth engine. External sales generated INR 41.9 billion in FY26 income and INR 14.7 billion in Adjusted EBITDA—crushing earlier management guidance of INR 10-12 billion.
Commissioned capacity accelerated 16.6% YoY to 12.6 GW, delivering on the execution promises of the IPP (Independent Power Producer) segment.
🐻 Bear Case
FY26 finance costs hit an agonizing INR 61.7 billion. As the debt pile for new construction activates, interest and depreciation expenses are severely masking the cash-generating ability of the assets.
Solar Plant Load Factor (PLF) decelerated to 22.7% in Q4 (down from 24.8% a year ago). When combined with known macro curtailment issues, resource inconsistency remains a structural risk.
⚖️ Verdict: ⚪
Neutral. ReNew is successfully pivoting from a pure-play IPP to an integrated renewable giant, with manufacturing providing a massive EBITDA cushion. However, escalating capital costs and Q4's profit implosion demonstrate the friction of their debt-heavy growth model.
Key Themes
Solar Manufacturing Becoming a Core Pillar
ReNew’s backward integration into solar cell and module manufacturing is accelerating. For Q4, the segment contributed INR 4.0 billion in Adjusted EBITDA on INR 11.9 billion in external sales (a ~33% margin). For the full FY26, it delivered INR 14.7 billion in EBITDA. With an additional 4 GW TOPCon cell facility under construction, this is no longer a side project—it is a primary growth driver insulating the company from module import volatility.
Finance Costs and Depreciation Erasing Profitability
The operational reality contradicts the top-line narrative. Finance costs and derivative changes reached INR 15.9 billion in Q4 alone (+9% YoY). Depreciation surged 48% YoY in Q4 to INR 7.9 billion as new projects came online. These fixed costs are entirely absorbing the EBITDA gains from new capacity, structurally suppressing Net Income.
Solar PLF Deceleration
While wind PLF improved (18.3% vs 17.4% YoY in Q4), Solar PLF showed a worrying deceleration, dropping to 22.7% from 24.8% a year ago. Total solar electricity sold dropped 5.1% YoY in Q4. Given management's previous commentary about pivoting away from wind toward solar for 'predictability', this underperformance contradicts the strategic narrative.
Capital Recycling Funding Engine
ReNew remains committed to its asset recycling strategy to fund growth without diluting equity. The company monetized assets effectively in prior quarters and finalized a $49 million sale of a 100 MW Tamil Nadu solar project to Technique Solaire Group in March 2026. This rotation strategy remains stable and vital for deleveraging.
Macro Factor: Grid Transmission and Curtailment
Though not heavily detailed in the Q4 release, previous quarters confirmed significant uncompensated curtailment (revenue losses) due to grid readiness lags and Temporary-General Network Access (T-GNA) status. This macro transmission bottleneck limits the actual cash generation of the 12.6 GW commissioned capacity.
Capacity Pipeline Execution
Commissioned capacity reached ~12.6 GW (+16.6% YoY) by Q4 end, with another 247 MW activated immediately after. By managing a 20 GW total portfolio, the baseline infrastructure for long-term contracted IPP revenues continues an accelerating trajectory.
Other KPIs
Stable but heavily elevated. Down sequentially from earlier in the year (e.g., INR 750 billion in Sept 2025), largely driven by internal cash generation and asset sales. However, it still casts a long shadow over free cash flow.
Reversing. CFe turned sharply negative in Q4 compared to INR (1,579) million in 25Q4. This was driven by elevated non-cash items, high working capital deployment, and tax/interest payouts. Despite a strong full-year CFe of INR 21.5 billion, Q4 demonstrates how volatile quarterly cash returns to shareholders remain.
Guidance
Decelerating. The midpoint (INR 106 billion) implies roughly 7.6% YoY growth. While positive, this is a steep deceleration from the 24.4% YoY growth achieved in FY26. It includes INR 10-12 billion from manufacturing, implying flat/down expectations for manufacturing margins as domestic supply normalizes.
Stable. Matches the exact construction guidance range provided at the start of FY26, maintaining a steady expansion pace for the IPP portfolio.
Decelerating. The midpoint of INR 20 billion implies a slight contraction from FY26's realized CFe of INR 21.6 billion. This points to higher anticipated loan repayments or interest expenses curbing shareholder cash accumulation.
Key Questions
Manufacturing Margin Sustainability
FY26 manufacturing EBITDA came in at nearly INR 14.8 billion, significantly beating prior INR 10-12 billion guidance. Yet, FY27 guidance models only INR 10-12 billion. Are you pricing in a collapse in module realizations, or is this guidance artificially conservative?
Solar Underperformance
Solar PLF dropped over 200 basis points YoY in Q4. Was this purely weather-driven, or are grid curtailment and T-GNA connection issues severely depressing effective generation rates?
Take-Private Offer Status
The consortium's non-binding take-private offer has been an overhang for multiple quarters. What is the Special Committee's definitive timeline for a resolution to remove this equity uncertainty?
Interest Rate Sensitivity
With finance costs surging 18% to INR 61.8 billion in FY26, what percentage of the current INR 687 billion net debt is exposed to floating rates, and what are the specific refinancing plans to arrest this margin compression?
