India’s wires and cables industry is booming, driven by a grid upgrade, record renewable additions and strong construction demand. In the April–June 2026 quarter, market leader Polycab India posted its highest‑ever first‑quarter revenue of ₹8,209.73 crore and a 39% year‑on‑year growth, while KEI Industries widened its margins with a 23% revenue rise to ₹3,185.34 crore and a 40.1% net profit increase to ₹274.14 crore. Polycab’s domestic W&C revenue grew 43% YoY and its EBITDA margin stood at 13.8%, whereas KEI’s margin was 13.0%. These figures illustrate a robust industry, not one in distress.

Despite these strong fundamentals, share prices of Polycab, KEI and RR Kabel have fallen since UltraTech Cement’s launch of its Ultravolt brand on 4 September 2026. The market reacted to the entry of a cash‑rich competitor with thousands of building‑material outlets, prompting a 9% drop in KEI’s shares on launch day and a continued 15–24% decline from 52‑week highs for all three incumbents. Investors feared that UltraTech’s distribution network could force price cuts and erode margins, rather than weaker demand.

UltraTech’s threat began in early 2025 when the company unveiled its plan in February, causing cable stocks to slump up to 15% before recovering. The company’s plant at Jhagadia, Gujarat, began commercial production on 1 September 2026, a few months ahead of its December 2026 deadline. UltraTech claims Ultravolt will be the second‑largest wires player by capacity at launch, aims to be a top‑two player within five years, and plans to sell through more than 5,000 UltraTech Building Solutions outlets, leveraging its cement‑building customer base.

The demand underpinning this expansion is real, driven by two forces: a once‑in‑a‑generation power grid rebuild and a construction cycle that now includes data centres, metros and factories. India added a record 55.3 GW of non‑fossil capacity in FY26, mostly solar, requiring extensive cable infrastructure to evacuate power. The Central Electricity Authority’s transmission plan foresees over ₹9.15 lakh crore of investment by 2032, including 1.91 lakh circuit km of new lines, directly boosting order books for EHV cables, where KEI’s sales jumped nearly 48% in Q1 FY27 and it still has a pending EHV order book of ₹793 crore.

Industry volumes have compounded at more than 15% a year over the last five years, with Crisil projecting the market to reach ₹1.2 lakh crore by the end of FY27, up from ₹90,000 crore in FY25. The market remains highly fragmented, with an estimated 400 players, and JM Financial notes that branded companies have steadily taken share from local manufacturers, from 61% of the market in FY14 to 76% in FY25. However, organised capacity is expected to grow 20–22% by FY27, outpacing volume growth of about 10%, which could compress pricing freedom.

The parallel with Aditya Birla Group’s paints entry shows that deep pockets and powerful distribution can erode margins before earnings recover. UltraTech’s Ultravolt, starting as the second‑largest wires player by capacity, may force incumbents to protect volumes at the expense of pricing. Investors should monitor gross margins, copper pass‑through speed, mix of EHV and export orders, and valuation multiples, as even a small dent in growth or margins can significantly impact share prices in this highly competitive market.
