* NII grew 23.3% YoY/10.3% QoQ to INR25.8b (in line), as NIM expanded 24bp QoQ to 5.96%. This growth was led by CoF reduction, lower day count, and lower interest reversals.

Highlights from the management commentary
* AUBANK’s 4Q is typically a seasonal quarter and better for credit costs. The bank targets credit costs of ~90bp for FY27E.
* The 1.8% RoA reported in 4QFY26 is partly seasonal. The bank aims to sustain ~1.8% RoA in FY27E. The key levers include improvement in the opex-to-assets ratio and moderation in credit costs, which are expected to be lower on a fullyear basis.
* CoF has likely bottomed out, with repricing offset by recent increases in deposit rates. ? Overall, the bank continues to target sustainable growth of ~2.0-2.5x India’s GDP growth.
Valuation and view
* AUBANK delivered a strong quarter, supported by robust growth, 24bp QoQ NIM expansion, and a sharp decline in credit costs. Margin expansion was driven by lower cost of funds, an improved asset mix, favorable day-count impact, lower interest reversals, and partial benefit from tax reversals. Growth continues to remain among the best in the industry, supported by a highyielding asset mix and strong momentum. We remain constructive on the bank’s underlying growth trajectory. Operating expenses are expected to moderate, leading to a decline in the C/I ratio towards ~56-57% over FY27-28E.
* Asset quality trends remain encouraging, with stress levels easing and a recovery visible in the unsecured portfolio. With NIM expansion, normalization in credit costs, and sustained business growth, we expect AUBANK to deliver best-in-class earnings growth in the medium term. We broadly retain our earnings estimates and expect a PAT CAGR of 35% over FY27-28. AUBANK remains our top pick among mid-size private banks. Reiterate BUY with a TP of INR1,275 (based on 3.4x Sep’27E BV).
