This growth was accompanied by an expansion in its customer base, which rose from 8.0 million in March 2025 to 8.3 million in March 2026, driven by aggressive acquisition strategies across retail and corporate segments.
The filing, made pursuant to Regulation 34(2)(f) of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, and SEBI Master Circular HO/49/14/14(7)2025-CFD-POD2/I/3762/2026 dated January 30, 2026, forms part of the bank’s annual report.

Sustainability and Environmental Initiatives
Under Principle 6, the bank detailed its environmental management practices, including the installation of solar power systems across six locations with a total capacity of 385kW. A new 75 KLD Sewage Treatment Plant (STP) was commissioned at the SIB Tower in Kakkanad, Ernakulam. The bank also implemented energy efficiency measures such as maintaining air conditioner temperatures at 24°C and procuring 5-star rated inverter ACs. Green financing remains a key focus, with the Green Deposit Scheme mobilizing ₹97.66 crore during the year. Of this amount, ₹156.28 crore (including ₹58.62 crore carried forward) was allocated to eligible green projects.
Social Impact and Governance
The bank reported that women constituted 46.28% of its total workforce, comprising 9,147 employees. More than 98% of employees were covered under training programs related to skill upgradation, health and safety, and compliance. Corporate Social Responsibility (CSR) initiatives reached more than 32 lakh beneficiaries, with over 71% belonging to marginalized and underserved communities. The bank’s CSR spending focused on healthcare, education, and environmental sustainability.
Governance structures were reinforced through an Executive Level Committee overseeing ESG implementation, chaired by the Chief Operating Officer. The Board’s Corporate Social Responsibility Committee, led by Non-Executive Non-Independent Director Benny P Thomas, oversees ESG reporting. Independent assessment of policies was conducted by CARE Analytics and Advisory Private Limited.
What the Numbers Show
The correlation between the 14.6% growth in total business and the >98% digital transaction share indicates a successful scaling of low-cost distribution channels. This operational efficiency likely contributed to the ability to expand the customer base by 300,000 users within a single year without proportional increases in physical infrastructure costs. Furthermore, the allocation of ₹156.28 crore to green projects against ₹97.66 crore mobilized suggests the bank is leveraging prior-year deposits to meet current sustainability targets, demonstrating active portfolio management toward environmental goals.
