BOSTON -- Loomis, Sayles & Company proudly celebrates the 15-year anniversary of a differentiated approach to growth equity investing under the leadership of Aziz V. Hamzaogullari, CFA, the founder, chief investment officer and portfolio manager of the Loomis Sayles Growth Equity Strategies (GES) Team. Aziz is also an executive vice president and a member of the firm’s Board of Directors.

·GES is a cohesive team with nearly 19 years of alpha generation and a long-term, private equity approach to investing.
·Under Aziz Hamzaogullari’s leadership since 2010, assets under management for GES have grown from $1.9 billion to nearly $91 billion as of 31 May 2025.

Aziz brought a differentiated approach to equity investing when he joined Loomis Sayles in 2010. A proprietary seven-step research framework supports the GES Team’s long-term, private equity approach to investing. The Team seeks to invest in those few high-quality businesses with sustainable competitive advantages and profitable growth only when they trade at a discount to the GES estimate of intrinsic value.

Underpinned by this singular investment philosophy, the GES Team expanded its platform from US-focused Large Cap Growth and All Cap Growth strategies to also include Global Growth, International Growth long-only strategies as well as the Long/Short Growth Equity hedge fund strategy. These strategies also are available in vehicles available to US investors.

The GES Team believes a focus on the quality of a manager’s investment philosophy, process and decision-making is essential for assessing the probability of future success. The GES alpha thesis encapsulates a deeply held system of persistent beliefs, a rigorous, repeatable investment process and substantive proof points.

“Since joining Loomis Sayles in 2010, Aziz and the GES Team have consistently distinguished themselves through a relentless focus on striving to achieve superior risk-adjusted returns for investors. Backed by their differentiated approach, they have demonstrated skilled and disciplined decision-making as well as a strong performance track record of which we are very proud,” said Kevin Charleston, chief executive officer of Loomis Sayles.

“I would like to thank our investors for their trust. We will continue to be committed to our guiding principles of long-term investing based on our key differentiated insights,” said Aziz V. Hamzaogullari, CFA, founder, chief investment officer and portfolio manager of the Loomis Sayles Growth Equity Strategies Team.

The cohesive GES Team has nearly 19 years of strong alpha generation in its domestic, global, international and long/short growth equity strategies as shown below.
