The key risks to Affiliated Managers Group (AMG) are primarily driven by its business model and the broader financial industry landscape:

1. Dependence on Market Conditions and Assets Under Management (AUM) Volatility: AMG's financial performance is highly sensitive to fluctuations in global financial markets, economic conditions, and investor sentiment. A decline in market values or a shift in investor preferences away from AMG's investment strategies can lead to reduced assets under management, directly impacting the fees generated and overall revenue. The company faces ongoing outflows from traditional active equity strategies, which it is working to offset through growth in alternative investments.
2. Operational Risks Associated with its Affiliate Model and Dependence on Affiliate Performance: AMG's business model relies on the performance and reputation of its independent Affiliates. Any adverse events affecting an Affiliate, such as poor investment performance, compliance failures, reputational damage, or cyber-attacks, could negatively impact AMG's business relationships and financial results. Furthermore, the concentration of assets within a few major Affiliates means that underperformance by these key firms could disproportionately affect AMG's consolidated financials.
3. Regulatory Changes and Increasing Compliance Costs: Operating in a highly regulated financial industry, AMG is exposed to complex and evolving regulations across various jurisdictions. Changes in regulatory requirements, including those related to environmental, social, and governance (ESG) factors or international tax laws (like the OECD's Pillar Two initiative), can increase compliance costs and necessitate significant operational adjustments, potentially impacting the company's financial condition.

• Global Asset Management Market: The global assets under management (AUM) market was valued at approximately USD 685.09 billion in 2024 and is projected to reach around USD 12,741.10 billion by 2034, growing at a compound annual growth rate (CAGR) of 33.95% from 2025 to 2034.
• Global Wealth Management Market: The worldwide wealth management industry is estimated to hold approximately USD 103 trillion in assets under management (AUM).

Affiliated Managers Group (AMG) is expected to drive future revenue growth over the next two to three years through several key strategies:

1. Expansion in Alternative Strategies and Private Markets: AMG anticipates continued growth by focusing on alternative investment strategies, particularly within private markets. The company has demonstrated success in raising substantial capital through its private market affiliates, indicating robust demand for these specialized strategies.

2. Strategic Investments in New and Existing Affiliates: A core part of AMG's strategy involves making equity investments in leading independent investment management firms. The company collaborates with these Affiliates, providing growth capital, product development expertise, and distribution support to enhance their evolution and magnify their long-term success.

3. Product Development and Distribution for the U.S. Wealth Market: AMG is actively working with its Affiliates to develop and distribute alternative products specifically tailored for the U.S. wealth market. This focus has already led to significant net inflows, such as with the AMG Pantheon fund, and is expected to continue contributing to revenue growth.

4. Evolution of Business Mix Towards Secular Growth Areas: The company is deliberately shifting its business mix towards areas experiencing secular demand, including private markets and sustainable investing. This strategic repositioning aims to enhance AMG's long-term organic growth profile by aligning with enduring market trends.
