Mahesh Patil, Chief Investment Officer (CIO) at Aditya Birla Sun Life AMC (ABSL AMC), has announced his decision to step down after nearly 21 years with the asset management company.

Patil, who has overseen assets under management (AUM) of approximately Rs 4.5 lakh crore, shared the development in a LinkedIn post, stating that he will hand over responsibilities to the next generation of leadership to pursue personal goals.

Leadership responsibilities will transition to Harish Krishnan as CIO – Equity, Kaustubh Gupta as CIO – Fixed Income, and Sunaina da Chuna as Co-CIO – Debt. Patil expressed confidence that the new leadership team will continue to meet investor expectations and drive the organisation’s growth.

Calling his association with ABSL AMC and the Aditya Birla Group a “privilege,” Patil highlighted the firm’s legacy and values, noting that the AMC which completed 30 years last year  is built on trust with integrity as a non-negotiable principle.

Reflecting on his career, Patil described his journey as one marked by passion and discipline, having navigated multiple market cycles. He leaves behind a strong performance legacy, particularly with the ABSL Large Cap Fund (formerly Frontline Equity Fund), which he has managed since November 2005. The fund, with an AUM of about Rs 31,000 crore, is ranked number one in its category over a 20-year performance period.

Patil credited this success to teamwork and mentorship, especially acknowledging ABSL AMC CEO A. Balasubramanian. He noted that fund management is a collective effort, noting the scale of responsibility across more than 50 equity and fixed-income strategies managed by the investment team.

By the end of calendar year 2025, a majority of its funds ranked in the top two quartiles over a one-year performance period, Patil noted. He emphasised the importance of robust investment processes in delivering long-term outcomes, pointing to several ABSL funds with over 20 years of track record as evidence of sustained wealth creation through compounding.
