NEW YORK, Oct. 9, 2025 /PRNewswire/ -- Mercer, a business of Marsh McLennan (NYSE: MMC) and a global leader in helping clients realize their investment objectives, shape the future of work and enhance health and retirement outcomes for their people, and MergerWare, a leading provider of digital M&A deal execution platforms, today announced a strategic alliance aimed at improving how organizations plan, manage, and execute mergers and acquisitions.

The alliance creates a seamless experience for clients by combining Mercer's extensive expertise in human capital, benefits, and risk management with MergerWare's innovative deal management technology. With this combination, the organizations aim to deliver a comprehensive solution that enhances efficiency, reduces risks, and accelerates deal timelines for our clients.

 Together, the alliance will help organizations:

• Simplify due diligence, accelerate decision-making, and improve transparency throughout the deal lifecycle.
• Uncover and address people-related risks with data-driven insights
• Deliver faster, smoother, and more sustainable integrations

"The key to creating deal value lies at the intersection of business and people strategy," said Jeff Black, Global Leader of Mercer's M&A Advisory Services. "Our alliance with MergerWare creates a new standard for deal execution by combining advisory expertise with innovative technology, giving clients the tools they need to achieve growth objectives while minimizing risks."

"This alliance is about empowering organizations with smarter, faster, and more strategic M&A processes," said Dhruv Mehra, Partner, Mercer M&A Advisory. "By integrating Mercer's human capital expertise with MergerWare's technology, we enable clients to focus on what truly drives long-term deal value: people."

Dharmendra Singh , Chief Executive Officer of MergerWare, added: "Too often, M&A failures are the result of weak execution and overlooked cultural alignment. By bringing together Mercer's deep advisory experience and MergerWare's digital execution platform, we are giving organizations a practical, technology-enabled approach to reduce deal failure rates and accelerate value creation."

Research shows that 70–90% of M&A deals fail to achieve their intended value, with cultural misalignment and operational inefficiencies among the leading causes. This alliance directly addresses those challenges, helping businesses overcome integration pitfalls by embedding structure, transparency, and accountability into every stage of the M&A process.

MergerWare , headquartered in the United States, is the industry leader in cloud-based M&A lifecycle management. The platform transforms complex, high-stakes transactions into a streamlined, data-driven experience, giving global deal teams a secure digital command center for every phase—from target screening and due diligence to execution and post-merger integration.

NEW YORK, May 5, 2025 /PRNewswire/ -- Mercer, a business of Marsh McLennan (NYSE: MMC) and a global leader in helping clients realize their investment objectives, shape the future of work and enhance health and retirement outcomes for their people, and the National Commission on Climate and Workforce Health, an initiative of the Health Action Alliance (HAA), today announced the launch of the Climate Health Cost Forecaster, a digital tool that enables employers to anticipate the financial impact of climate-driven health risks on their workforce.

This model, developed by Mercer, provides business leaders with data-driven projections that estimate the long-term healthcare costs associated with extreme heat, poor air quality, flooding and hurricanes. It offers a unique, localized view of workforce vulnerability across industries and geographies.

Extreme weather can have a range of direct and indirect health effects on individuals, from heat stroke to mental health issues, including depression. These events can at times be catastrophic, costing lives and leaving communities and businesses struggling to recover, rebuild and pay for the damage they left behind.

The Forecaster is powered by a combination of weather data, epidemiological research and Mercer's proprietary health cost modeling — data being brought together in a tool designed for employers. It gives companies a tangible way to assess and plan for the health-related financial risks a changing climate already imposes on their workforce.

Notably, the Forecaster reveals that employees working in climate-controlled environments experience approximately 40% lower healthcare costs on average compared to their counterparts in non-climate-controlled settings. Certain industries, including agriculture, utilities and construction, face up to double the healthcare cost risks due to climate-related factors.

"Employers now have access to data that makes the cost of climate-related health risks visible and actionable," said Susan Potter, Mercer's US and Canada President and Commission Co-Chair. "While 77% of workers say they've already been affected by extreme climate events, only 4% of employers have assessed which employees are most at risk. The Forecaster connects the dots between extreme weather, people risk and rising healthcare costs. It empowers business leaders to prioritize employee health and turn risk into readiness."

The tool is part of a growing portfolio of resources developed by HAA through the National Commission on Climate and Workforce Health. The Commission is presented by Mercer with additional support from Elevance Health and The Hartford, and brings together business, public health and sustainability leaders to mobilize employers in strengthening workforce resilience in the face of climate disruption.

"The Forecaster results may be surprising for some organizations, for example, the top risk across all industries in Portland, OR, is air quality, while the top risk in Hartford, CT, and Burlington, VT, is extreme heat. Of course, the results may fluctuate widely depending on an employer's industry and the portion of their workforce in a climate-controlled environment. Still, they illustrate the importance of knowing the risks in the locations where you do business," said Tracy Watts, Mercer's US Leader for Healthcare Policy. "You have to know the risk to address the risk."

David Leathers, HAA's Climate & Health Program Director, added: "We're proud to launch an innovative solution that brings the financial impact of extreme weather on workforce health into focus. With billion-dollar disasters accelerating—and hurricane and wildfire season around the corner—this couldn't be more timely."
