Growth thesis
Frontier Springs manufactures railway springs, forgings, and safety systems (Kavach/FIBA) for Indian Railways, with 90%+ revenue from core railway components. Key segments include coil springs (60% of FY26 revenue), air springs (30%), and forging (10%), with forging set to scale via a 6-ton hammer and defense/mining diversification. Growth is driven by a ₹300+ crore order book, 30% FY27 revenue growth target, FIBA trials (₹40-50 crore TAM post-RDSO approval), and capacity expansions (air springs to 300 coach sets/month). Revenue is projected to rise from ₹322 crore (FY26) to ₹500 crore (FY27) as forging diversifies into defense and margins stabilize at 26-27%. The critical execution risk is delayed FIBA commercialization, which could push revenue contributions to FY28.
Why is Frontier Springs Ltd stock rising?
Gross revenue guidance of ₹500 crores for FY27, representing ~30% growth over FY26
Order book of ₹300+ crores providing strong revenue visibility into FY27
FIBA (failure indication and brake application) product received basic RDSO approval; trials starting in trains with commercialization expected in later part of FY27
FIBA targeting a ₹100 crore addressable market for Vande Bharat and LHB coaches, aiming ₹40-50 crore business share after trials
6-ton hammer in forging division now operational; scaling forging vertical is a clear priority for FY27
