Volume inflection on Salai Banwa: can ACC hold margins in a soft season?
ACC reports Q2 FY27 on October 27 with 2.4 MTPA new capacity online, sector tailwinds flagging, and Street pricing in 27% upside. Here's what to watch for.
What to expect
ACC's Q2 FY27 print will be the first full quarter to reflect the commissioning of the 2.4 MTPA Salai Banwa greenfield grinding unit (Sep 30, 2026) and the 1 MTPA Kalamboli expansion. Against Q1's 10 MnT volumes and ₹457 Cr EBITDA, the Street and company guidance point to mid-single-digit volume growth this quarter, but the real question is margin hold. Q2 is traditionally softer seasonally for cement demand; ACC will need efficient absorption of the new capacity and disciplined cost management to defend EBITDA/ton in the ₹800–850 range (vs ₹910/ton in Q1 FY27).
~₹5,900–6,100 Cr
Volume growth + price realization; Axis sees 7–8% sector growth Q2FY27
~₹480–520 Cr
On prior guidance ₹4,250/ton cost; margin compression vs Q1 is baseline expectation
~11.5 MnT
Reflects Salai Banwa ramp + 8% FY27 growth target; trade share to hold >75%
₹800–850
Sector benchmark under pressure; watch fuel mix, RE power share, & dispatch costs
A strong Q2 looks like: volume growth above 10%, EBITDA/ton holding at or near ₹850, trade sales mix maintained, and Salai Banwa ramping to 80%+ utilization. A weak Q2 flags lower volumes (sub-8% growth due to softer demand), margin erosion below ₹800/ton from input cost inflation or underutilization, or a delay in Salai Banwa ramp.
On track?
ACC is tracking its FY27 guidance of 8% volume growth and ₹4,250/ton cement cost. Q1 FY27 revenue (₹5,808 Cr) and margin (₹457 Cr EBITDA, ~7.8% margin) align with a normalized, mid-cycle run-rate. The company's target to reach ₹4,000/ton by FY28 via debottlenecking (5.6 MTPA at USD 48/t capex) signals confidence in operational leverage. Two caveats: (1) sector volume growth is slowing—Axis projects only 7–8% for Q2FY27, not the 10%+ the Street priced in at the start of the year; (2) EBITDA/ton has been under pressure across the sector (fuel costs, RE power constraints, coal/coke inflation), which will limit ACC's margin expansion. A good Q2 will show ACC can absorb this headwind with new capacity.
What the Street says
Since last quarter
Operational highlights:
Sep 30, 2026
Greenfield grinding unit (UP); immediately accretive to volumes
Salai Banwa 2.4 MTPA commissioned
Oct 6, 2026
LIC nominee; governance addition; no operational impact
Vivek Paul appointed Non-Exec Director
Jul 24, 2026
Power offtake security; ₹53.1 Cr; non-core but supports margin stability
Amplus Andhra 26% stake acquired
Aug 5, 2026
Alleged compliance failure (unspecified); risk item to monitor; no trading halt
SEBI administrative warning
Jul–Aug 2026
NCLT and shareholder approvals in progress; corporate action risk; disclosure on result day possible
Ambuja Cements merger scheme pending
The Salai Banwa ramp is the centerpiece. The Amplus power stake secures offtake and may help dampen fuel-cost volatility. The SEBI warning is routine administrative noise (no material impact signaled). The Ambuja merger remains an overhang; any Q2 disclosure or timing update could move the stock beyond the result itself.
What to watch on October 27
1 · Salai Banwa utilization and ramp trajectory
Management will telegraph Q3 FY27 production and volumes. If Salai Banwa is already at 70%+ utilization and ramping to full capacity, the Street will upgrade FY27 volume guidance and cement-cost trajectory. If ramp is slower, margin pressure deepens.
2 · EBITDA/ton trend and FY27 cost guidance
Will ACC maintain the ₹4,250/ton cost guidance or pre-guide down due to input inflation (coal, RE power scarcity)? A hold signals confidence; a cut would suggest margin compression is deeper than seasonal and reflects structural headwind.
3 · Ambuja merger status and capex/debt implications
Any update on merger approval timeline, financing, or regulatory clarity could move the stock ±10% independent of the result. Debt and capex capacity are material; check whether merger capex assumptions are embedded in FY27/28 guidance.
ACC is in a setup phase: new capacity is live, the Street is pricing in a bull case of 27% upside, but sector volume growth is flagging and margins are under pressure. Q2 FY27 will show whether the company can execute a clean ramp while defending EBITDA/ton against a softer demand environment. Volume beat is likely (Salai Banwa online), but margin hold is the real test. Expect the print to hinge on (1) full utilization color on the new facility, (2) cost management and any guidance reset, and (3) merger news, which could eclipse the quarter itself.
