M&M Shares Jump Steeply on GST Rate Rationalisation

New Delhi, 4 September 2025: Mahindra & Mahindra Ltd shares jumped nearly 7% in early trading on Friday after a historic Goods and Services Tax reform. In the new format approved by the GST Council, the tax rate on small cars, entry-level motorbikes, and auto parts has been reduced from 28 percent to 18 percent. The action caused a rally in auto stocks, with M&M taking the lead and touching new all-time highs.

Record Highs Push M&M Shares to ₹3,497 With Heavy Trading Volumes

By about 11:45 am IST, M&M shares were quoting at ₹3,497.00 and registering a new 52-week high. This upsurge was coupled with high trading volumes and strong turnover, reflecting investor fervor. The Nifty Auto index surged strongly, reaching near 11-month highs, riding on advances in M&M and auto peers.

GST Rate Rationalisation Lowers Tax from 28% to 18% on Key Auto Segments

The GST reform simplifies the erstwhile four-slab structure to two main slabs—5 percent and 18 percent—by removing the 28 percent slab and auto sector cess. Small cars below four meters and motorbikes below 350 cc can now be rated under the 18 percent slab, and heavier ones could invite a 40 percent duty—although net prices will continue to fall with cuts in input costs and tax burden.

M&M, Maruti Suzuki, and Hero MotoCorp Identified as Key Beneficiaries 

Emkay Global equity analysts do point out M&M, along with Maruti Suzuki and Hero MotoCorp, as among the key beneficiaries of the GST restructure. The constant 18 percent rate on auto components solves the earlier “inverted duty” problem, likely to enhance margin structures and simplify compliance for manufacturers.

Lowered Tax Burden Could Accelerate M&M Volume Growth and Market Share

M&M’s spurt is not only a policy-facilitated pickup in demand opportunities for compact cars and mass two-wheelers, but also better affordability for a significant segment in India’s automotive market. If the lowered tax burden translates into substantial price reductions and renewed consumer appeal, M&M may experience volume growth acceleration and market share gains. Yet consistent outperformance will hinge on realised demand pickup, competitive reaction, and execution in the face of changing macroeconomic factors.
