ACME Solar Q1 FY27: Revenue 63% YoY, EBITDA 56%, PAT 80%

Earnings call sets the tone for a record quarter

ACME Solar Holdings Limited reported its strongest quarter yet in Q1 FY27, with management highlighting record revenue, EBITDA, and profit. The update came through the company’s earnings conference call dated July 30, 2026. Management attributed the performance to improved plant utilisation, contributions from its battery energy storage system (BESS) business, and capacity additions. The company also pointed to an expansion in its asset base following new commissioning activity, including batteries. The quarterly numbers were accompanied by a higher full-year capital expenditure guidance, signalling an accelerated buildout plan for FY27.

Key financial results: revenue, EBITDA, and profit hit new highs

For Q1 FY27, total revenue was INR 954 crore, up 63% year-on-year. EBITDA came in at INR 831 crore, up 56% year-on-year, indicating that operating profitability rose alongside revenue. Profit after tax (PAT) was INR 235 crore, up 80% year-on-year. Management described the quarter as a milestone, with the highest-ever revenue and EBITDA in the company’s history.

The company also provided margin details across the portfolio. Overall EBITDA margin was around 87%, with the renewable portfolio delivering about 88%-89% EBITDA margin and BESS delivering around 82%. A separate disclosure in the provided material also referenced core renewable EBITDA margin of about 91% excluding BESS, underscoring a margin gap between the generation portfolio and storage operations.

Margin and PAT margin: what was reported

ACME Solar’s reported margins show a high-margin operating profile, particularly in renewables. The materials include two different references for PAT margin: one section states PAT margin of around 45%, while the call transcript excerpt cites a PAT margin of around 25%. The transcript itself is labelled as a preliminary version that may contain inaccuracies and may be updated.

For readers tracking earnings quality, this difference matters because PAT margins can vary based on financing costs, depreciation, and one-off items. The company also disclosed cost components for BESS in the transcript excerpts, including an interest portion of around INR 32 crore and depreciation of around INR 47 crore.

BESS contribution: INR 226 crore revenue, largely short-term

A key driver discussed on the call was the growing contribution from the battery energy storage system business. Management said BESS generated INR 226 crore of Q1 FY27 revenue from power sales, out of the INR 954 crore total. The revenue mix was skewed toward near-term contracting: about 85% came from short-term contracts, while the remaining portion came from merchant sales.

The company also noted that BESS is becoming a major earnings driver, supported by commissioning momentum during the quarter. In the provided material, ACME Solar said it commissioned about 2.3 GWh of BESS capacity in the quarter, taking cumulative commissioned BESS capacity to about 3.62 GWh. Management described this as roughly 40% of India’s cumulative commissioned BESS capacity.

Operations: CUF at a record high and generation growth

On the operating side, management highlighted stronger utilisation. Capacity Utilization Factor (CUF) rose to 30.9%, the highest in company history, compared with 28.5% in the prior-year quarter. Higher CUF was one of the key reasons cited for revenue and EBITDA growth.

The materials also mention higher power generation, but there is a data inconsistency across the provided text. One line states power generation increased 23% year-on-year to 20 million units, while another section states power generation: 2,020 million units, up 23% year-on-year. The document notes the transcript is preliminary and may contain inaccuracies.

Capex and asset base: guidance raised for FY27

The company said it incurred around INR 3,000 crore of capital expenditure during the quarter. It also upgraded full-year capex guidance to INR 15,000-20,000 crore for FY27. The higher guidance aligns with the company’s ongoing commissioning and battery expansion activity.

ACME Solar also reported that its asset base expanded to about INR 25,000 crore following commissioning of new assets and batteries. The combination of high capex, new commissioning, and rising BESS contribution was framed as central to the company’s FY27 execution plan.

Market reaction: stock falls despite operational update

Despite the record operating performance, the stock reaction described in the provided material was cautious. The shares were reported down 1.83% at 359.95 in recent trading after a prior close of 366.65. The provided text reports these prices with a dollar symbol, even though the company is listed on NSE, and the numbers are presented here as stated.

The divergence between earnings momentum and near-term stock movement suggests that investors were weighing the strong results against the capital intensity implied by the upgraded capex guidance.

Why the quarter matters: mix shift toward storage

The quarter’s key theme is the rising weight of BESS in ACME Solar’s revenue mix, with INR 226 crore from BESS alone in Q1 FY27. Alongside this, the company reported a record CUF of 30.9%, supporting higher renewable generation monetisation. Management’s decision to raise FY27 capex guidance to INR 15,000-20,000 crore indicates that storage commissioning and renewable additions remain central to the growth plan.

Conclusion

ACME Solar’s Q1 FY27 update combined record financial results with a clear push toward scaling BESS, supported by improved utilisation across its renewable portfolio. The next set of checkpoints will be execution against the higher FY27 capex plan and further clarity on contracted versus merchant exposure in BESS revenues, as discussed in the earnings call materials.
