IDFC First Bank

Investment case

Turnaround: liability franchise ahead of profits

Why this business

Private-sector universal bank formed from the 2018 merger of IDFC Bank and Capital First, now a retail/MSME-focused lender with loans of Rs 3.05 lakh crore (+20.6% YoY) and customer deposits of ~Rs 3 lakh crore (Jun-2026). It has one of the highest CASA ratios among private banks (50.8%) and a 5.9-6.0% NIM, but a 70%+ cost-to-income ratio and the FY25-26 microfinance stress kept FY26 ROA at ~0.4%. No identifiable promoter (promoter holding 0%); Warburg Pincus (~9.5%) and ADIA (~5.1%) became anchor investors via a Rs 7,500 cr CCPS issue in 2025.

What we believe

1. 01Earnings inflection: Q1FY27 PAT Rs 1,075 cr (+132% YoY, 61% above street) vs FY26 full-year PAT of ~Rs 1,600 cr; management guides FY27 ROA ~1% (FY26: 0.4%) and a medium-term 1.7-1.8% ROA.
2. 02Credit cost past peak: MFI book shrank to Rs 6,700 cr with SMA normalised at 0.71% and 93% CGTMSE cover; FY27 credit-cost guidance lowered to 150-160 bps (from 170-180); gross slippages -30% YoY.
3. 03Liability franchise is the moat: CASA ratio 50.8% (+283 bps YoY), customer deposits +16.6% to Rs 3 lakh cr, cost of funds stabilised ~6%, NIM 5.96% with FY27 guidance raised to 5.8%.
4. 04Operating leverage: cost-to-income improved 310 bps YoY to 70.7% with ~500 bps positive jaws; management targets <70% in FY27, with each 100 bps roughly 10% of PAT at current scale (our arithmetic on Rs 1,075 cr quarterly PAT is not sourced - treat as illustrative).
5. 05Capital in place: CET1 13.33% / CAR 15.05% after the Rs 7,500 cr Warburg/ADIA CCPS converted in Oct-2025, plus a fresh Rs 20,000 cr enabling resolution (27-Jul-2026); 1.5x book for a bank moving from 0.4% to 1% ROA.

Why now

1.54x trailing book (BV Rs 56.2) and 32x TTM PE (screener, 7-Sep-2026); Axis Direct values it at 1.3x FY28E ABV. Historical 5y average not sourced; 52-week high Rs 87 (Feb-2026). EV/EBITDA n.m.; dividend yield 0.3%.

Market disagreement

• AU Small Finance Bank: AU trades at a much richer ~3x+ book (screener data on AU's FY26 PAT was inconsistent and is not relied on) as a universal-bank-licence candidate; IDFC First already has the universal licence, a 50.8% CASA ratio (vs AU's ~30%) and is at a lower 1.5x book with ROA doubling in FY27.
• Federal Bank: Federal (18x PE, 2.1x P/B, ROE 12%, Q1FY27 PAT -18% YoY per screener) is a steadier but lower-growth franchise (NIM ~3%); IDFC First offers 20%+ loan growth, 5.9% NIM and far larger ROA upside from 0.4% to 1.7-1.8%.
• IndusInd Bank: IndusInd (1.2x book, FY26 PAT Rs 889 cr, ROE 1.4%, Q1FY27 PAT -15%) is cheaper but is still repairing its derivatives/MFI accounting lapses and leadership; IDFC First has cleaner governance, rising ROA and Warburg/ADIA backing.

Position sizing

Turnaround Mid cap  2.3% of the PMS on $31 Jul 2026 (August rank 20). Satellite positions are owned for an asymmetry, sized up when the cycle rewards risk and reduced when it does not.

Catalysts

• Q2FY27 results (Oct-2026): sustaining >Rs 1,000 cr quarterly PAT and cost-income below 70% would confirm the FY27 1% ROA guidance.
• Announcement of the RBI-approved timing/structure of the Rs 20,000 cr capital raise approved on 27-Jul-2026 and any inclusion in large-cap indices as market cap crosses ~Rs 75,000 cr.
• Microfinance normalisation: bank targets 15% MFI book growth by FY27-end with 93% CGTMSE cover; further credit-cost guidance cut below 150 bps.

Risks and response

• Cost-to-income at 70.7% is the highest among large private banks; if opex growth re-accelerates (branch/tech build, Chandigarh-branch deposit fraud one-offs in Q4FY26), the ROA path to 1% slips.
• Q1 beat leaned on a one-off Rs 515 cr CGFMU recovery (used to create a contingency provision amid West-Asia conflict concerns); underlying ROA was ~0.9% adjusted, so a rural/MFI relapse or unsecured retail stress would push credit cost back above 1.6%.
• Dilution/overhang: 81.26 cr new shares from CCPS conversion (Oct-2025) plus a fresh Rs 20,000 cr enabling resolution; ROE only 9% in Q1FY27 and FY26 ROE 3.8%, so book compounding is slow until ROA reaches 1.5%+.
