The construction of power transmission facilities in India has been among the most capital-intensive build-outs in the nation's history. As India plans to generate 500+ GW of renewable energy by 2030, there will be a need for substantial growth in the power transmission network to transport this power from its generation sites to consumers, and Sterlite Power Transmission Limited (SPTL) is among the top private organizations involved in this process.

Originally created through the demerger of Sterlite Technologies in 2018 and sponsored by the Vedanta Group ecosystem, Sterlite Power Transmission has emerged as one of India's largest private power transmission companies, operating along the Tariff-Based Competitive Bidding (TBCB) pathway in India and internationally in Brazil. Although numerous attempts have been made to float shares in the Indian markets, shares of Sterlite Power remain unlisted and can only be traded via the OTC pre-IPO market. This unique position, considering the size of the organization, attracts many pre-IPO investors to Sterlite Power annually.

Here is all that you need to know about Sterlite Power unlisted shares in 2026.

Sterlite Power Unlisted Share Price Today

Unlisted Sterlite Power shares are trading at approximately ₹490 per share on the OTC dealer market as of May 2026, with a minimum lot size of 50 shares and an initial investment amount of ₹24,500. This significant increase of ~61% within the last year is due to the resurgence in the company’s IPO activity, increased transmission orders, and the overall revaluation of India’s power sector.

Sterlite Power's 60%+ increase in its OTC share price in 12 months is due to two main reasons: increased policy focus on the transmission infrastructure sector in light of the government's National Electricity Plan 2023-32 (contemplating investment of Rs 9.15 lakh crore into the electricity segment) and anticipation of an IPO from Sterlite Power in FY25-26. As in any other case in the OTC market, any rise in prices is likely to be volatile, especially considering thin market liquidity.

Lot Size and Minimum Investment Requirement

The usual lot size of Sterlite Power's unlisted shares in the OTC market is 50 shares. This makes the company a relatively cheaper pre-IPO stock with a minimum investment of Rs 24,500 at current prices. The lot size can go higher, from 200 shares to even 500, depending on the category of investors, especially those who are looking to buy the stock ahead of an IPO listing announcement.

Sterlite Power — Company Overview

Sterlite Power Transmission Limited is among the top power transmission infrastructure companies of India’s private sector – undertaking development, construction, and management of interstate and intrastate power transmission projects along with production of high quality conductors and cables via its Products Division.

Demerger from Sterlite Technologies (2018) and Group Structure

The demergers of Sterlite Power occurred in November 2018 when Sterlite Power was separated from Sterlite Technologies Limited (NSE: STLTECH), which resulted in the creation of two companies. In essence, Sterlite Technologies kept its core operations in optical fibre and data networks, and Sterlite Power took over all operations in power infrastructure and conductor manufacturing. After the demerger, Sterlite Technologies continued to operate as a listed entity on NSE and BSE, but Sterlite Power remained unlisted.

Sterlite Power belongs to the Vedanta Group ecosystem, with Pratik Agarwal, the son of Vedanta's founder, Anil Agarwal, holding the position of Managing Director. Their extensive experience in natural resources and infrastructure financing has enabled Sterlite Power to participate actively in bids for large TBCB transmission projects and obtain project-level financing.

Business Mix: Transmission Projects and Products

The company derives its income from two major segments having different financial traits.

• Power Transmission Infrastructure (Projects Division): This represents the main business segment that includes project awards through TBCB (Tariff-Based Competitive Bidding) processes organized by PGCIL (Power Grid Corporation of India) and state-level transmission companies, and subsequent execution and operation of high voltage transmission lines and substations on an interstate and intrastate basis. The revenue generated by the Projects Division is primarily annuity-based after completion, where profits are regulated by the central or state electricity regulatory commission.

• Products Division (Conductors & Cables): The Products Division involves manufacturing of HTLS (High-Temperature Low-Sag) conductors, regular ACSR/ACSS conductors, OPGW (Optical Ground Wire), and specialty cables for power transmission and distribution applications around the world. The division earns income from sales to third-party customers, which include Power Grid, state discoms, and overseas utilities.

Geographic Presence: India and Brazil

Apart from India, Sterlite Power also has an international presence in Brazil, where the company operates through its subsidiary Sterlite Brasil, which is involved in the transmission concession auctions conducted by Brazil's national electricity agency, ANEEL. Brazil serves as a critical growth driver in the long term due to its rapid expansion of the power grid network in line with India's TBCB model. The business in Brazil adds to the income streams but also comes with foreign currency exposure and political risks.

The story of Sterlite Power from a finance perspective can be considered to be an excellent infrastructure growth story. This means that there will be revenue growth of 20-35% per year based on the execution of the company’s increasing order book. The EBITDA margin will keep improving with the scaling of the Products division. On the other hand, the PAT margin is being constrained by the infrastructure project debt, which is a characteristic of most projects undertaken by companies through the TBCB bid process.

How Sterlite Power Compares to Listed Peers

The table below benchmarks Sterlite Power against its primary listed comparables. All listed peer data sourced from NSE/BSE earnings filings and Moneycontrol (FY2024).

The key takeaway from this analysis: Power Grid Corporation generates extraordinary EBITDA margins (approximately 87%) due to its regulatory regime providing assured returns, which makes its business model entirely distinct from that of Sterlite Power (project-based development and EPC + ownership). More relevant listed company comparisons include Adani Energy Solutions and KEC International, in which case the margin performance of Sterlite Power is superior. In such an event, if SPTL is given a multiple on Revenue comparable to that of Adani Energy Solutions or KEC International, there would be significant upside potential.

Sterlite Power IPO Status

Sterlite Power's IPO history is one of the most closely watched — and repeatedly frustrated — listing stories in India's infrastructure sector. Understanding this history is essential context for any pre-IPO investor evaluating the exit thesis.

IPO Attempts, Withdrawals, and Renewed Plans — A Timeline

The problem of repeatedly postponing the listing does not apply exclusively to Sterlite Power; there are numerous examples in India involving big companies in infrastructure (such as IRB Infrastructure, PNC Infratech, etc.) that postponed their IPOs because of rising interest rates or unfavorable conditions in the capital markets. In each case, the delay represents evidence of good capital management decisions since the company’s management opts to wait until a favorable time for a listing rather than issue stock at a low price.

2026 IPO Outlook — What to Watch

As of May 2026, Sterlite Power’s IPO readiness has never been stronger in recent years. Among the positive factors that favor an IPO, these could be noted: a close-to-record backlog of transmission orders (~₹17,000 crore), improved PAT margins due to older project annuitization, favorable industry trends such as growth of renewable energy infrastructure in India, and a favorable primary market climate for companies from the infrastructure space, thanks to the IPO success of Adani Energy Solutions, NTPC Green, among others. As of writing, no definite DRHP issuance has been reported to SEBI for 2026.

According to sources followed by Mint and the Economic Times, the company might go public in FY2026-27 if economic conditions remain favorable. This should be taken as an estimate rather than a definitive event.

What Post-IPO Lock-In Means for Pre-IPO Holders

However, for non-promoter pre-IPO investors, once Sterlite Power makes its Initial Public Offering, then these investors shall have to abide by SEBI’s mandatory lock-in period of six months as per the ICDR Regulations 2018. This means that any OTC buyer currently would be unable to offload their shares when Sterlite goes public irrespective of the listing premium.

Why Sterlite Power Pre-IPO Is Watched

With all its complexities surrounding its IPO story, Sterlite Power continues to be among the most talked-about stocks on India’s pre-IPO unlisted market. The investment thesis is multi-faceted but built upon structural, long-term growth themes..

How to Buy Sterlite Power Unlisted Shares

Buying unlisted shares in Sterlite Power will involve a typical OTC demat purchase procedure. With the company making news again about an upcoming IPO, the availability of dealers should be fine but the prices may change rapidly — so proceed with confidence after completing your research.

Risks of Investing in Sterlite Power Unlisted Shares

SPTL represents a strong case of infrastructure-led growth, but the opportunity also comes with several notable risks, which need to be taken into consideration alongside the growth story. Below is a comprehensive risk discussion for SPTL.

• Project Execution Risk – Complexity in Large Infrastructure Projects: A power transmission infrastructure project involves complex coordination among agencies: acquisition of right-of-way across hundreds of kilometers of land, obtaining forest and environmental approvals, clearances and permissions from state governments, and procurement of multiple contractors for executing the project. Any delays in each stage are fairly common and have immediate repercussions on the revenue recognition timeline and project-level returns on investment (IRRs). Even a single delay in one large project is enough to impact SPTL's overall consolidated financial performance.

• Working Capital Requirement – Pressure on Cash Cycles: The nature of EPC work is very working capital intensive, requiring funding on capital costs, subcontracting payments, and construction before the milestone-driven payments are received from customers. With an increasingly larger order book at SPTL, the company will require increasing amounts of working capital funding – through a combination of project-specific borrowing and corporate borrowings. A credit tightening environment or a rise in interest rates will

• Interest Rate Sensitivity: Projects requiring lengthy construction periods and annuities as their revenue model are highly interest rate-sensitive. The interest rate hikes seen in 2022-23 (the Repo rate was increased by 250 bps between May 2022 and February 2023) had contributed to the postponement of SPTL's IPO listing process in that period. Another rise in rates could pose problems and possibly lead to yet another delay in the IPO. Source: Monetary policy statements of RBI (2022-23)

• Governance Risk — the Vedanta Angle: Governance issues have been associated with Vedanta Group in relation to its various companies. The debt restructuring plans of Vedanta Limited, attempts to de-list the company, and the numerous inter-firm transactions in the Vedanta Group family of companies are well-documented in reports from Mint, the Economic Times, and elsewhere. While the Sterlite Group runs as an independent entity, the association with the group leads to what one may call the "Governance Discount" leading to depressed prices relative to comparable standalone firms in the infrastructure space.

• IPO Delay Risks — A Known Pattern: The mere fact that Sterlite has been delaying its IPO listing process for six years now itself constitutes a risk factor. Every delay

• Brazil Operations - Foreign Exchange Risk and Sovereign Risk: The Brazil operations of Sterlite Power will be subject to foreign exchange risk in addition to sovereign risks related to Brazil. The utility sector in Brazil is very different compared to that in India, both economically and in terms of regulations, which can have an impact on consolidated accounts.

Frequently Asked Questions

1. What is Sterlite Power unlisted share price?

The unlisted shares of Sterlite Power (SPTL) as on May 2026 are currently available at around ₹490 per share in the Over-the-Counter dealer segment. The minimum number of shares traded is 50, resulting in a minimum investment of about ₹24,500. It is just an indicative price based on information provided by the dealer network, which may fluctuate. You should always check the current stock price through a SEBI-registered intermediary.

2. Is Sterlite Power part of Vedanta?

Sterlite Power belongs to the Vedanta Group family and is backed by Pratik Agarwal, the son of Vedanta Group founder Anil Agarwal. But, in actuality, Sterlite Power Transmission Limited is an individual company, having its own management and financials separate from the parent company. Therefore, Sterlite Power is not a subsidiary of Vedanta Limited (the company listed on NSE and BSE). The relation with the Vedanta Group family impacts perception regarding governance, but the company is not operationally connected to Vedanta Limited.

3. When is Sterlite Power IPO?

At the time of writing in May 2026, there have been no reports of any IPO dates or new SEBI DRHP filings by Sterlite Power. Since 2018, the company has undergone several phases of IPO preparations and postponements. According to sources in Mint and the Economic Times, the firm may list its shares in FY2026-27, contingent on favorable macroeconomic trends.

4. What does Sterlite Power do?

Sterlite Power Transmission Limited is one of the biggest private power transmission infrastructures companies in India. It participates in TBCB (Tariff-Based Competitive Bidding) tenders in India as well as transmission franchises in Brazil for executing power transmission projects. Additionally, it produces HTLS, ACSR/ACSS conductors, OPGW, and specialty cables via its Products division. The company backs IndiGrid InvIT, India's first InvIT in the power sector that consists of SPTL transmission infrastructure facilities already under commissioning.

5. How to buy Sterlite Power unlisted shares?

The shares of Sterlite Power can be acquired using off-exchange demat transactions by means of OTC intermediary sites. The steps include: (1) having an existing demat account with a DP linked to CDSL/NSDL, (2) doing the KYC formalities with a registered dealer, (3) ensuring the ISIN and demat holding with the seller, (4) making payment only by NEFT/RTGS/IMPS, but never in cash, and (5) getting a confirmation for demat credit in 2 to 5 business days.

6. Is Sterlite Power profitable?

The Sterlite Power business is profitable on the PAT front, with PAT estimated to be around ₹350-450 crore for FY2024. Nonetheless, as in all major infra businesses, profitability will be pressured due to substantial depreciation on commissioned assets and interest expenses on debt incurred to finance projects. The EBITDA margin of around 22% indicates the strength of the business operations. The PAT margins are relatively lower, at ~6-7% of revenues, owing to the debt burden.

7. Is Sterlite Power a good pre-IPO investment?

The case of Sterlite Power as an IPO candidate is compelling: growth in the pipeline (~₹17,000+ crore), the super cycle in the Indian power transmission sector, improvement in EBITDA margins, the route to monetisation of IndiGrid InvITs, and experience of management in successfully acquiring and implementing large scale TBCB projects. Then there are also considerations that cannot be ignored: history of six plus years since IPO announcement, questionable corporate governance practices at Vedanta group level, heavy working capital requirement, and interest rate sensitivity.
