Renewable Energy Stock With a 66% Revenue CAGR Over the Last Decade; Do You Own It?

Synopsis: A solar EPC player has compounded revenue at a 66.5% CAGR over the past decade, crossing ₹1,700 crore consolidated revenue in FY26 while strengthening its balance sheet into a net-cash position after listing. Backed by an asset-light model and expanding solar opportunities, management is targeting another strong growth year, although execution and policy-related risks remain key monitorables.

Built on a decade of consistent execution, this renewable energy player has emerged as a key participant in India’s solar transition through an asset-light business model and expanding project portfolio. The piece examines its growth strategy, financial performance, operational scale, future expansion plans, management outlook, and the execution and policy risks that investors should keep an eye on.With a market capitalization of approximately Rs. 2,939 crore, the shares of GK Energy Limited were trading at around Rs. 145 per share, with a 52-week range of Rs. 239.60 to Rs. 87. It is trading at a P/E of approximately 14x

A decade of compounding, not a one-year spike

The first thing that stands out about GK Energy is how long this growth has been running. Over the last ten years, standalone revenue has grown at a 66.49% CAGR, from just Rs.15.6 crore in FY17 to Rs.1,532.5 crore in FY26. EBITDA compounded even faster at 87.68%, PAT at 104.36%, and net worth at 91.87%.

This isn’t a business that got lucky in one good year; revenue crossed the Rs.1,000 crore mark only in FY25, and then grew another 40% on top of that in FY26, which suggests the growth curve is still steepening rather than flattening out.

FY26: the year revenue crossed Rs.1,500 crore for the first time

On a consolidated basis, revenue for FY26 came in at ₹1,715.3 crore, up 56.67% year-on-year from ₹1,094.8 crore in FY25. EBITDA grew 56.07% to ₹318.4 crore, with EBITDA margin at 18.56% (broadly flat versus 18.64% in FY25). PAT grew 53.37% to ₹204.3 crore, with PAT margin at 11.91%, slightly lower than FY25’s 12.17%.

For the quarter, Q4 FY26 consolidated revenue was ₹476.8 crore, up 35.24% year-on-year and up from ₹352.5 crore in Q4 FY25. Q4 EBITDA came in at ₹86.5 crore (up 28.30%), and Q4 PAT was ₹59.3 crore (up 32.16%).

A large and growing execution footprint

The scale of ground-level execution here is genuinely large for a company of this size. Cumulatively, GK Energy has installed over 140,000 systems across 7,500+ villages, involving solar pumps, rooftops, and power plants, adding up to 617 MW of renewable capacity since inception. In FY26 alone, the company installed 276 MW (up from 184 MW in FY25) through 61,085 systems (up 33.8% from 45,655 in FY25). The workforce supporting this stood at 1,300+ people, backed by a 40+ vehicle owned logistics fleet for last-mile delivery to remote areas.

One thing worth flagging here: management had originally guided for 70,000–75,000 pump installations for the year but delivered 61,085. On the earnings call, the CEO attributed the shortfall to unseasonal rainfall in Maharashtra and a raw material supply hiccup in the last few weeks of March, and said the company is targeting roughly double this year’s volumes in FY27. That’s a reasonable explanation, but it’s still a miss against original guidance and worth keeping in mind when sizing next year’s targets.

The asset-light model is the structural differentiator

GK Energy doesn’t manufacture its own solar pumps, panels, or controllers. Instead, it works through a network of OEM/ODM partners while retaining control over quality standards, raw material sourcing, and design specifications. 

Management described this as having “all the benefits of owning a factory without the capex”  the company controls critical components (cells, modules, controllers, pump assemblies) and works with multiple manufacturing partners across states like Chhattisgarh, Gujarat, UP and Kerala, which also cuts down transportation costs.

This shows up clearly in the balance sheet. Inventory days fell from 31 to just 21 days, and capacity utilisation has scaled to 15,000+ systems a month without any major capex outlay. Compared to an integrated manufacturer, this model typically means lower fixed overheads, higher operating leverage, and better ROCE  though it also means margins depend heavily on how well the company manages its supplier relationships, since it doesn’t control production costs directly.

Balance sheet turned net cash after the IPO

GK Energy listed on the NSE and BSE on 26 September 2025. Following the IPO, the balance sheet turned meaningfully stronger on a consolidated basis too: the company moved from a net debt position of ₹154.98 crore in FY25 to a net cash surplus of ₹237.79 crore in FY26. Consolidated total cash stood at ₹443.28 crore by FY26, up from ₹62.81 crore in FY25, while total borrowings were largely stable at ₹205.5 crore (versus ₹217.79 crore in FY25). 

That said, working capital days did stretch on a consolidated basis too  net working capital days rose from 90 to 101, and debtor days rose from 120 to 125, largely tied to collection cycles from state utility companies. On the other hand, creditor days actually fell from 61 to 42, showing the company paying suppliers faster even as collections lengthened. Management said on the call that they expect working capital (standalone, which they track more closely) to stabilize around the 140–150 day range going forward, rather than improve dramatically from here. 

Order book and what’s driving the next leg of growth

As of the most recent update, the order book stood at Rs.710 crore, including orders received after April 2026. Beyond the core solar pumping business (its largest revenue driver, tied to schemes like PM-KUSUM and Maharashtra’s Magel Tyala Saur Krushi Pump Yojana), the company is expanding into solar rooftop (having already installed over 5 MW under Maharashtra’s “Smart Scheme”) and eyeing utility-scale ground-mounted EPC and BESS (battery storage) as future verticals.

Management’s stated ambition is to double FY26’s revenue in FY27, targeting somewhere between Rs. 2,500 and 3,000 crore, split roughly as Rs. 2,200–2,400 crore from pumps and Rs. 600–1,000 crore from rooftops, and also projecting Rs. 3,000 crore plus in future business. 

Importantly, on the call, the CEO clarified that this target holds even if the anticipated PM-KUSUM 2.0 scheme sees further delays, since the company can lean on its Maharashtra order pipeline and rooftop expansion in the interim. He also clarified that the “double-digit margin” guidance refers specifically to PAT margin, not revenue growth, a distinction worth keeping straight since the two get used interchangeably in some coverage.

Where the risks sit

A few things are worth watching. First, revenue is currently concentrated heavily in Maharashtra, since that’s where the bulk of the country’s solar pumping volume originates. Geographic diversification is still a work in progress, with the company present in six states (UP, Haryana, Rajasthan, MP, Maharashtra, Chhattisgarh) but not actively expanding into new ones this year. 

Second, the business remains meaningfully dependent on government scheme timing  PM-KUSUM 2.0 has already been pushed from an expected April rollout to around June-end, and further delays could compress FY27 growth.

Third, an investor on the call raised a fair question about a Rs.90 crore addition to fixed assets for a “corporate office” in a company that otherwise runs asset-light management clarified this was effectively a fixed deposit converted into a real estate asset for bank guarantee purposes, rather than a shift away from the asset-light model, but it’s the kind of line item worth tracking in future filings.

The bottom line

GK Energy’s pitch rests on a genuinely differentiated model, deep rural distribution, an asset-light manufacturing partnership structure, and multi-decade policy tailwinds around India’s solar pump and rooftop adoption. 

The FY26 numbers back up the growth story, and the balance sheet is now in a healthier net-cash position post-IPO. But the FY26 installation shortfall against guidance and the ongoing dependence on scheme timing are real considerations, and the doubling target for FY27 will be the first real test of whether this compounding continues at the same pace as a listed company.
