Cable stocks faced heavy selling pressure on September 4, 2026, after UltraTech Cement formally launched Ultravolt, its new wires and cables business. The announcement raised fears that a financially powerful new competitor could disrupt pricing, dealer incentives, market share and profit margins across the industry.
This was not simply another company entering a fast growing market. UltraTech plans to begin at national scale, become one of the top 2 players within 5 years and use an established construction ecosystem that most new entrants would need years to build.
Why Cable Stocks Are Falling Today.
During September 4 trade, KEI Industries fell as much as 8.25% to ₹4,855.75, while Polycab India was down 6.25% at ₹8,273.50 at around 1.41 PM IST. RR Kabel subsequently traded around 9% lower, while Havells India and Finolex Cables declined approximately 4.02% and 3.62%, respectively. Polycab share price, KEI Industries share price, RR Kabel share price.
UltraTech Cement moved in the opposite direction and gained as much as 2% during the session. Investors appear to believe that Ultravolt could create a new growth engine for UltraTech, while simultaneously reducing the future growth and valuation premium enjoyed by established cable companies.
What Is UltraTech Ultravolt.
Ultravolt is the Aditya Birla Group wires and cables business housed within UltraTech Cement. The company has committed ₹1,800 crore and has started with home wires, flexible wires and cables for residential, commercial, industrial and infrastructure applications.
The new manufacturing facility is located at Jhagadia in the Bharuch district of Gujarat. UltraTech says Ultravolt is already the second largest wires player by capacity at launch and aims to become one of the top 2 industry players within 5 years.
Ultravolt plans an initial rollout across more than 500 districts and 6,000 pin codes. It wants to reach more than 1 lakh retailers, use over 5,000 UltraTech Building Solutions outlets and support distribution through more than 20 warehouses.
Why Did Cable Stocks Fall When UltraTech Entry Was Already Known.
UltraTech first announced its proposed entry into wires and cables in February 2025. At that time, the company approved approximately ₹1,800 crore of capital expenditure and expected the Gujarat facility to be commissioned by December 2026.
The latest announcement changes the risk assessment because the facility has started earlier than initially expected. More importantly, UltraTech has now revealed the scale of its capacity, national distribution plans and ambition to become a top 2 player.
The market therefore did not react to the existence of Ultravolt. It reacted to evidence that UltraTech intends to compete aggressively from the beginning rather than slowly testing a few regional markets.
How UltraTech Can Put Pressure on Cable Company Profits.
A cable manufacturer generally earns revenue by selling through distributors, retailers, contractors, electricians and institutional customers. To capture market share quickly, a new entrant can offer higher dealer incentives, introductory discounts, additional credit and heavy advertising support.
Existing companies may then need to reduce prices or spend more on distributors and marketing. Revenue can continue growing in this situation, but the profit earned from every ₹100 of sales can decline.
Nuvama estimates that greater competition and channel investment could create a gross margin impact of around 1.50% to 2.50% for incumbents, compared with its earlier expectation of 1.00% to 1.50%. The final impact could be smaller if companies compensate through premium products, higher volumes and operating efficiencies.
The sensitivity is meaningful because leading companies currently operate with margins in the low to mid teens. If a business earns a 13% operating margin and competition removes 2 percentage points without any offset, operating profit could decline by roughly 15% even if revenue remains unchanged.
Why KEI, Polycab and RR Kabel Fell More Than Havells.
The size of the stock reaction broadly reflects how dependent each company is on wires and cables. In Q1 FY27, wires and cables contributed 97.08% of KEI Industries sales, making KEI highly sensitive to any change in industry pricing or market share.
Polycab generated ₹7,155.3 crore from wires and cables against consolidated revenue of ₹8,209.7 crore in Q1 FY27. This means the segment contributed approximately 87% of revenue, while its segment EBIT margin stood at 13.3%.
RR Kabel generated around 91% of Q1 FY27 revenue from wires and cables. Havells is more diversified, with cables contributing ₹2,456 crore of its ₹6,510 crore Q1 FY27 revenue, or approximately 38%, which helps explain its relatively smaller share price decline.
Is UltraTech Really Capable of Disrupting the Cable Market.
UltraTech enters with 3 advantages, capital, distribution and relationships. Its connection with individual home builders, contractors, property developers and engineering companies gives Ultravolt access to many customers who already buy UltraTech cement and other building products.
The electrician engagement programme is equally important because electricians frequently influence the wire brand selected by homeowners. Ultravolt had onboarded more than 1,600 electricians before launch and plans to train over 40,000 during the coming year.
UltraTech may also benefit from the nearby raw material ecosystem of Hindalco, another Aditya Birla Group company. However, any commercial benefit from this relationship will depend on procurement terms and execution and should not automatically be assumed.
Why Established Cable Companies Still Have Strong Defences.
The Indian wires and cables market was estimated at approximately ₹90,000 crore in FY25 and is expected to grow at around 11% to 13% annually through FY30. Organised companies increased their market share from 61% in FY14 to 76% in FY25, which means industry growth and movement away from unorganised manufacturers can create room for multiple large brands.
Polycab already holds an estimated 30% to 31% share of the organised market. Established companies also possess mature distributor networks, manufacturing experience, electrician relationships and broader portfolios covering high tension, extra high voltage, export and specialised cables.
Ultravolt is initially focused on wires and low tension cables. It will still need to prove product acceptance, repeat dealer orders, capacity utilisation and sustainable profitability before becoming a direct threat across every cable category.
Why Valuations Made Cable Stocks Vulnerable.
Before the selloff, several leading cable stocks traded at premium earnings multiples because investors expected strong industry growth, market share gains and healthy margins. When a stock trades near 50 times earnings, even a small reduction in expected growth or profitability can produce a large share price reaction.
For example, if earnings remain unchanged but the valuation falls from 50 times earnings to 45 times, the theoretical share price declines by 10%. This explains why cable stocks can fall sharply before UltraTech has generated meaningful revenue or taken measurable market share.
The current correction therefore reflects both earnings risk and valuation risk. Investors are reducing the price they are willing to pay for future profits because the competitive environment has become less predictable.
What Ultravolt Could Mean for UltraTech Cement Earnings.
The ₹1,800 crore investment is meaningful for the new business but manageable relative to UltraTech scale and cash generation. Assuming an illustrative asset turnover of 4 times, the investment could eventually support revenue of around ₹7,200 crore.
At an eventual EBITDA margin of 10% to 12%, that revenue could generate approximately ₹720 crore to ₹864 crore of annual EBITDA. These are scenario estimates based on brokerage assumptions and depend on utilisation, pricing, product mix and execution rather than confirmed company guidance.
Jefferies estimates that the business could eventually contribute approximately 3% to 7% of UltraTech FY30 revenue and EBITDA. The opportunity is attractive for UltraTech, although early advertising, distributor incentives and low capacity utilisation could keep Ultravolt profitability weak during the initial ramp up.
Should Investors Worry About the Cable Stocks Crash.
The selloff is fundamentally understandable because UltraTech has increased the probability of tougher pricing and higher channel spending. KEI, Polycab and RR Kabel deserve greater near term scrutiny because wires and cables form the majority of their revenue.
However, the decline should not be interpreted as proof that incumbent earnings will collapse. Industry demand remains strong and established companies continue to report healthy growth, with Polycab domestic wires and cables revenue rising 39% and KEI domestic wires and cables sales growing 29.31% in Q1 FY27.
The decisive evidence will come from dealer incentives, price changes, gross margins, advertising expenses and Ultravolt capacity utilisation. Until these numbers appear, the stock reaction represents a rational competitive risk adjustment rather than confirmation of permanent market share loss.
