India’s cement industry is entering a critical phase in the December quarter as the impact of the Goods and Services Tax (GST) rate cut begins to fully reflect in market pricing and company earnings. The reduction of GST on cement from 28% to 18%, implemented in September 2025, was aimed at lowering construction costs and improving affordability across housing and infrastructure segments. However, the immediate consequence for cement manufacturers has been a visible softening of prices, raising concerns around near-term profitability.
Prices Ease Despite Volume Support
The December quarter marks the first complete three-month period after the GST revision, and industry data indicates that cement prices have declined by approximately 3% on a sequential basis across India. The correction has been more pronounced in the southern and eastern regions, where competitive intensity remains high and demand recovery has been slower.
Average cement realisations during the quarter are estimated at around ₹330–335 per 50-kg bag, compared with nearly ₹370 in the preceding quarter. While the GST cut has reduced the tax burden, the extent of price reduction suggests that competitive pressures and weak non-trade demand have also played a role, beyond pure tax pass-through.
Margin Pressure to Dominate Q3 Earnings
The decline in realisations is expected to weigh on operating margins for most cement producers in the December quarter. Although dispatch volumes have remained healthy, supported by infrastructure spending and ongoing housing projects, analysts believe the benefit of operating leverage is being offset by weaker pricing and elevated input costs.
Fuel expenses, particularly pet coke and power, remained volatile during the quarter, limiting cost savings. As a result, average EBITDA per tonne for the sector is expected to moderate to a range of ₹750–1,050, compared with levels exceeding ₹1,000 per tonne in the first half of the financial year. Companies with stronger operational efficiencies and cost controls are likely to fare relatively better, but overall margin contraction appears unavoidable.
Net Profit May Grow, but Quality of Earnings in Focus
On a year-on-year basis, many cement companies are still expected to report higher net profits in Q3, aided by volume growth and a relatively low base in the corresponding quarter last year. However, investors are increasingly focused on the quality and sustainability of earnings rather than headline profit growth.
The December quarter is likely to highlight the disconnect between volumes and profitability, with price-led margin pressure emerging as the central theme of the results season for the sector.
Broader Earnings Context and Sector Implications
The cement industry’s performance comes amid a mixed corporate earnings backdrop for the December quarter. While some sectors are expected to deliver strong profit growth, cement is emerging as a sector where policy-led price correction and market dynamics are temporarily working against margins.
Over the longer term, the GST rationalisation is expected to support demand by improving housing affordability and reducing overall construction costs. Industry estimates had earlier suggested a potential reduction of ₹30–35 per bag following the tax cut. However, the near-term impact has been front-loaded on pricing, while demand benefits are likely to materialise gradually.
Outlook: Short-Term Pain, Structural Demand Intact
In the coming quarters, cement companies will be closely monitoring whether lower prices translate into stronger demand traction, particularly in the retail and affordable housing segments. A sustained pickup in volumes could help restore pricing power and margin stability.
For now, the December quarter results are expected to reflect a phase of adjustment — where policy intent supports long-term growth, but short-term earnings bear the cost of transition. The ability of cement producers to navigate this phase through cost efficiency and disciplined pricing will determine earnings resilience in FY26.
