While mentioning his journey at Aditya Birla Sun Life AMC, Patil called it a 'privilege'. He posted, “Working at ABSL AMC and the larger Aditya Birla Group has been a privilege. ABSL AMC is one of the oldest asset management companies (celebrated 30 years last year) and an institution which is built on trust, where integrity is non-negotiable.”

Calling his journey immensely fulfilling, driven by passion and discipline, Patil said he has navigated the fund house through multiple market cycles while leaving behind a strong legacy. The flagship ABSL Large Cap Fund (formerly Frontline Equity Fund), which he managed since November 2005, had an AUM of Rs 31,000 crore and ranked No.1 in its category over a 20-year period.

Patil credited this success to the support of his team and his mentor A. Balasubramanian, who is CEO at ABSL AMC.

“I genuinely believe fund management to be a team effort, especially when we are managing more than 50 different strategies across equity and fixed income. I am grateful to my team of FMs, analysts, traders and other investment staff for their dedication and contribution to my success,” Patil said while thanking his team.

By the end of calendar year 2025, the majority of funds managed by the fund house ranked in the top two quartiles in performance over the one-year period. “We have many funds with more than 20 years vintage, and they are a testimony of the power of compounding and wealth creation for investors,” he added.

In his message, Patil thanked investors, distributors and shareholders for their trust and support over the years, noting their role in the fund house’s growth. He added that he looks forward to sharing insights drawn from his 35-year journey as an investment professional in the future.
