It's a firm built on helping clients navigate the complex world of risk, strategy, and people.

2025 Financial Performance: Breaking Down the Growth

This segment generated $3.9 billion in revenue in Q3 2025, a 13% jump from the prior year. Marsh itself, the insurance broking arm, saw its revenue climb by 16% to $3.4 billion for the quarter. That's a clear sign that demand for core risk transfer and advisory services is not slowing down.

Profitability also saw a significant lift. Adjusted earnings per share (EPS) for the third quarter rose 11% to $1.85, and adjusted operating income increased 13% to $1.4 billion. What this estimate hides is the underlying efficiency gains from the company's focus on operational improvement, which is helping to expand margins even as they invest in new technology like AI initiatives.

That kind of performance doesn't happen without a laser focus on a clear mission.

Component 1: Leading Professional Services-The Pursuit of Excellence

The first core component is the aspiration to be the 'leading professional services firm.' This isn't just about size; it's about setting the standard for quality, integrity, and value delivery. For a firm like Marsh & McLennan, 'leading' means attracting and keeping the best talent, plus consistently delivering exceptional client value.

To be fair, this is a capital-intensive business, and you have to invest to lead. In Q1 2025, the company's consolidated revenue hit $7.1 billion, with underlying revenue growth of 4%, which shows their core business is healthy. They are also actively centralizing investments in operational excellence, data, Artificial Intelligence (AI), and analytics through a new Business and Client Services unit. The goal is simple: use technology to simplify operations, elevate service quality, and drive innovation, so they can reinvest those efficiencies back into client value. You can't lead without innovation.

• Attract and retain top talent globally.
• Invest in AI and data for service excellence.
• Maintain the highest standards of quality and integrity.

Component 2: Expertise in Risk, Strategy, and People

The mission's second component defines the firm's scope: 'risk, strategy, and people.' This is the integrated value proposition (the unique set of services offered) that sets Marsh & McLennan apart from single-service competitors. They look at your business holistically. Risk, strategy, and people are the three critical areas where organizations either succeed or fail.

The Risk and Insurance Services segment, which includes Marsh and Guy Carpenter, is the largest, generating $4.8 billion in Q1 2025 revenue. This segment is not just selling insurance; it's providing unparalleled advice on new risks. For example, Marsh recently issued a carbon credit insurance policy on a US-based carbon removal project for Microsoft, directly addressing the emerging challenges of climate change. On the Consulting side, which includes Mercer and Oliver Wyman Group, they reported total revenue of $2.371 billion in Q2 2025. Mercer's focus on health, wealth, and career consulting helps clients manage the 'people' element-the human capital-which is defintely a core part of any successful strategy.

Component 3: Global Impact and Client Success

The final component, often implied in the mission's scope, is the commitment to 'global impact' and helping clients 'thrive.' This means serving clients in over 130 countries and leveraging diverse perspectives to tackle complex, worldwide challenges.

The firm's success is directly tied to client success, which is why their adjusted Earnings Per Share (EPS) is expected to be about $9.58 for the full fiscal year 2025, an 8.9% increase over 2024. This growth is a direct result of clients valuing their advice, especially in uncertain times. They are making a difference in the moments that matter, whether it's navigating geopolitical events or building climate resilience. This global reach and client-centric approach are essential for tackling systemic risks that no single country or company can solve alone.

A vision is useless without the right values to guide the daily work. MMC's core values-integrity, client-first, excellence, and mutual respect-are the ethical guardrails for their 90,000+ colleagues operating in over 130 countries.

The value of integrity, for example, is non-negotiable, especially in a business built on trust and handling massive amounts of client capital. The company's commitment to this is defintely tested when dealing with complex global regulations, like the new UK offense of failure to prevent fraud which came into force on September 1, 2025.

• Integrity: Upholding the highest ethical standards globally.
• Client-First: Tailoring solutions to client needs, not just selling products.
• Excellence: Delivering superior results and expert advice.

Integrity

Integrity is the bedrock of any professional services firm, especially one dealing with complex risk and capital. For Marsh & McLennan Companies, Inc., this value means ethical conduct, transparency, and doing the right thing, even when it's difficult. It's about building trust with clients, colleagues, and the wider community.

A key 2025 action demonstrating this commitment is the firm's proactive response to evolving global regulations on financial crime.

This shows zero tolerance for bribery, corruption, or fraud, and it's a clear action that protects clients and shareholders from reputational and financial risk.

Respect

It's a business imperative because diverse perspectives are essential for solving the complex, global challenges clients face-from climate resilience to geopolitical risk.

The firm continually invests in its colleague value proposition, and a key focus area in 2025 is Inclusion and Diversity (I&D). While specific 2025 EEO-1 data isn't fully public yet, the firm's I&D strategy is overseen by the Board's Corporate Responsibility Committee, which receives regular reports on progress. This high-level governance ensures accountability for maintaining an equal-opportunity culture. Honestly, if you don't have an inclusive culture, you can't attract the best talent.

Teamwork

In a firm with four distinct, market-leading businesses-Marsh, Guy Carpenter, Mercer, and Oliver Wyman-Teamwork is how they deliver the 'Power of Perspective'. It means seamlessly bringing together expertise across risk, strategy, and people to give clients a unified solution. You want the best of all their capabilities, not just one silo.

A major structural move in the third quarter of 2025 was the creation of Business and Client Services (BCS). This new function is a direct investment in better teamwork, designed to accelerate client impact and efficiency by improving collaboration and technology across the businesses. This kind of internal restructuring, which is defintely a big lift, shows a concrete commitment to making it easier for clients to access the full range of the firm's services, which is what led to the $5.7 billion in adjusted operating income for the first nine months of 2025.

Excellence

Excellence is the pursuit of being the world's leading professional services firm in risk, strategy, and people. It's about delivering exceptional value to clients, which is best measured by consistent financial performance and strategic investment. The firm's adjusted earnings per share of $7.63 for the first nine months of 2025, a 9% increase from the prior year, is a clear marker of this financial excellence.

Excellence also means staying ahead of the curve through innovation. For instance, the acquisition of Validate Health in 2025 is a concrete example of investing in cutting-edge technology and data-driven insights to enhance client solutions, particularly in the health and benefits space. Plus, the firm's commitment to sustainability, with a goal to reduce absolute Scope 1 and 2 greenhouse gas (GHG) emissions by 50% by 2030 from a 2019 base year, shows a forward-looking view of operational excellence that extends beyond just the bottom line.
