INVESTMENT PHILOSOPHY

Since 1 July 2006

With the 20-year anniversaries of the Loomis Sayles Large Cap Growth and the Loomis Sayles All Cap Growth strategies, Loomis Sayles proudly celebrates 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.

Celebrating 20 Years of The Power of Active Management Done Right

  • GES is a cohesive team with 20 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 $97.4 billion as of 30 September 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 and International Growth long-only strategies as well as a Long/Short Growth Equity hedge fund strategy. These strategies are available in the US through vehicles including mutual funds, managed accounts, CITs and an ETF as well as UCITS and other vehicles outside the US[1].

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 Growth Equity Strategies (GES) Team have exemplified excellence through their unwavering commitment to delivering superior risk-adjusted returns for our clients. Their distinctive investment philosophy, grounded in a disciplined and differentiated approach, has consistently driven strong performance. We are immensely proud of the GES Team’s achievements and the lasting impact they continue to make,”
Kevin Charleston, Chief Executive Officer, Loomis Sayles

“I want to sincerely thank our investors for their continued trust and confidence. We remain firmly committed to our core principles of long-term investing, guided by the differentiated insights that define our approach,”
Aziz V. Hamzaogullari, CFA
Founder, Chief Investment Officer and Portfolio Manager, Loomis Sayles Growth Equity Strategies Team

Growth Equity Strategy Team Alpha Thesis

For investors, a major challenge is to identify those portfolio managers who are most likely to deliver superior risk-adjusted returns in the future. Understanding how an investment philosophy informs a manager’s decision-making can provide meaningful insights into how and why a particular manager generates alpha.

KEY INVESTMENT RISKS FOR THE LARGE CAP GROWTH AND ALL CAP GROWTH STRATEGIES

Equity Risk

The risk that the value of stock may decline for issuer-related or other reasons.

Market Risk

The risk that the market value of a security may move up or down, sometimes rapidly and unpredictably, based upon a change in market or economic conditions.

Non-US Securities Risk

The risk that the value of non-US investments will fall as a result of political, social, economic or currency factors or other issues relating to non-US investing generally. Among other things, nationalization, expropriation or confiscatory taxation, currency blockage, political changes or diplomatic developments can negatively impact the value of investments. Non-US securities markets may be relatively small or underdeveloped, and non-US companies may not be subject to the same degree of regulation or reporting requirements as comparable US companies. This risk is heightened for underdeveloped or emerging markets, which may be more likely to experience political or economic stability than larger, more established countries. Settlement issues may occur.

Smaller or Mid-Sized Companies Risk

The risk that the equity securities of these companies may be subject to more abrupt price movements, limited markets and less liquidity than investments in larger, more established companies.

Liquidity Risk

The risk that the strategy may be unable to find a buyer for its investments when it seeks to sell them.

Non-Diversified Strategies

Non-diversified strategies tend to be more volatile than diversified strategies and the market as a whole.

Currency Risk

The risk that the value of investments will fall as a result of changes in exchange rates, particularly for global portfolios.

Derivatives Risk (for portfolios that utilize derivatives)

The risk that the value of the Strategy’s derivatives instruments will fall because of changes in the value of the underlying reference instrument, pricing difficulties or lack of correlation with the underlying investment.

Leverage Risk (for portfolios that utilize leverage)

The risk of increased loss in value or volatility due to the use of leverage or obtaining investment exposure greater than the value of an account.

Counterparty Risk

The risk that the counterparty to a swap or other derivatives contract will default on its obligations.

Models and Data Risk

The strategy may utilize quantitative model-based strategies. This is the risk that one or all of the quantitative or systematic models used may fail to identify profitable opportunities at any time. These models may incorrectly identify opportunities and these misidentified opportunities may lead to substantial losses. Models may be predictive in nature and may result in an incorrect assessment of future events. Data used in the construction of models may prove to be inaccurate or stale, which may result in investment losses.

General Risk

Any investment that has the possibility for profits also has the possibility of losses, including loss of principal.
