1. At a Glance

A B Infrabuild posted its seventh consecutive year of growth in FY26, with sales rising to ₹256 crore and net profit to ₹19.3 crore. That’s the headline. But inside the numbers sits a puzzle: revenues up 23%, profit up 20%, yet the company’s cash position deteriorated sharply. Operating cash flow swung from ₹5.4 crore into negative ₹51.2 crore.

The stock sits at ₹10.13 (prices referenced are not live). At that level, the market values the enterprise at ₹645 crore—a P/E of 33, nearly double its 5-year average of 17.75 (median construction peer). An order book of ₹846.75 crore provides revenue visibility. But working capital intensity of 266 days means cash gets locked in for nine months before it returns. That’s both the company’s curse and its invisible anchor.

The question isn’t whether ABIL grows. It’s whether growth can fund itself without draining the balance sheet.

2. Introduction

A B Infrabuild was incorporated in 2011 and headquartered in Mumbai. Amit Bholanath Mishra is the promoter with two decades of construction sector experience. The company migrated from SME to the main board of NSE and BSE in May 2023, signalling institutional legitimacy.

Over the past three years, the business has scaled from ₹122 crore (FY23) to ₹184 crore (FY24) to ₹256 crore (FY26). Compound growth at 28% annually. At the same time, promoter holding has fallen from 59% to 31%, a loss of 28 percentage points since FY22. More on that later.

The company operates Grade “AA” contractor status with MCGM and Class 1(A) with PWD Maharashtra. Its core work is railways—platform construction, gauge conversion, track formation, rail-over bridges. Roughly 85% of execution happens in Mumbai; roughly 61% of the order book targets railway projects. This is either a superb moat or a catastrophic concentration risk, depending on state policy.

3. Business Model: WTF Do They Even Do?

ABIL bids for contracts in infrastructure—primarily railways, secondarily roads, bridges, dams. The tender model is competitive and win-dependent, not recurring revenue. Margins are tight, execution windows are long, retention money (2–5 years) locks cash, and unbilled revenue sits on the balance sheet until handover.

The railway specialisation is deliberate. Projects are large and sticky. The cost structure is straightforward: raw materials, labour, subcontractors. Overheads are light. The company doesn’t have factories, inventory of finished goods, or distribution networks. It has equipment, project teams, and a reputation.

Orders come, work happens, invoices flow (slowly), cash trickles back (slowly). The working capital cycle at 266 days is longer than the average construction firm’s patience. That’s what happens when 61% of your order book sits with Indian Railways—the gold-standard client but the slowest payer.

4. Financials Overview

Figures are consolidated, in ₹ crore.

Quarterly Trajectory (Q4 FY26): The final quarter came in hot. Sales of ₹83.9 crore were the strongest of the year. Operating profit of ₹12.1 crore delivered a margin of 14.4%—steady, unremarkable, unsurprising. Net profit of ₹5.97 crore. The quarter is balanced, not a blowout. Management flagged on the Q4 results that the year saw execution delays in H1 FY25 (general elections + Maharashtra elections) and acceleration in H2. Fresh orders of ₹500 crore came in during FY25; the company ended with an order book of ₹846.75 crore as of April 20, 2025.

On Guidance: Management flagged margins will hold steady at 10–11% going forward, a step below the current run rate of 14.9% OPM. This is the honest forecast—not all projects yield equal margins, and competitive tenders will compress them.

5. Valuation Discussion: Fair Value Range (Educational Only)

What follows is a walkthrough of how three valuation methods work, using this company’s numbers as the example — not a target, not a forecast, not advice.

Method 1 (P/E Multiples): Annualised EPS for FY26 is ₹0.30 (full-year EPS, no multiplication required). Peer multiples for construction contractors range 17.75x (median across 118 construction peers) to 55.82x (Rail Vikas Udyam). ABIL sits at 33.3x currently. Across the peer band of 17.75x–35x, the arithmetic produces ₹5.32–₹10.50.

Method 2 (EV/EBITDA): EBITDA for FY26 is ₹38.0 crore. Net debt is ₹56.24 crore (borrowings ₹88.25 cr minus cash ₹32.01 cr). Enterprise value at current price ₹10.13 is ₹701 crore. Peer EV/EBITDA multiples span
