The biggest mergers and acquisitions in 2025

Key Concepts

M&A Rebound (2025): Significant increase in global merger and acquisition activity despite market uncertainties.
Mega Deals: Transactions exceeding $10 billion, particularly prominent in 2025.
Dry Powder: Large amounts of capital held by investors ready to be deployed in acquisitions.
Value Bridges & Contingent Payments: Structuring techniques used to mitigate risk in uncertain markets.
Strategic Buyers: Companies acquiring others to strengthen their position and create synergies.
AI in M&A: Increasing role of Artificial Intelligence in deal sourcing, due diligence, and execution.
Business Valuation: The process of determining the economic worth of a company, increasingly reliant on AI-driven data analysis but still requiring human interpretation.

2025 M&A Landscape and Outlook for 2026

The year 2025 witnessed a substantial rebound in global Merger and Acquisition (M&A) activity, defying initial concerns surrounding tariffs and market instability. Global deal value is projected to reach $4.8 trillion by year-end, representing a 30-36% increase year-over-year. This surge indicates a shift in mindset, where companies are adapting to constant uncertainty and prioritizing capital deployment despite prevailing market conditions. As Mackenzie Regent, Managing Partner of KELAS LLP, stated, “Uncertainty is the new certainty, and deals will continue regardless of the prevailing market conditions.”

Drivers of the 2025 M&A Boom

Several factors contributed to this growth. A significant amount of “dry powder” – capital waiting to be invested – fueled dealmaking. Market participants are increasingly utilizing “value bridges” and “contingent payments” to navigate uncertainty. These are structuring techniques designed to bridge valuation gaps and share risk. The overall sentiment is that companies cannot afford to remain passive, prompting them to actively pursue acquisitions and consolidation.

Canadian M&A Activity in 2025

Canada experienced a particularly strong year for M&A, characterized by a surge in “mega deals” – transactions exceeding $10 billion. There were 63 such deals in Canada, a 147% increase compared to the previous year’s typical deal size. “Strategics” – companies acquiring others to enhance their core business – were the primary drivers of this activity, aiming to achieve greater strength through consolidation.

Case Studies of Canadian Deals:

Cenovus and MEG Energy: A $7.9 billion deal creating one of Canada’s largest oil sands platforms. This deal exemplified how competitive tension can maximize shareholder value. The initial offer represented a 0% premium, but intervention from Strathcona Resources ultimately drove a more favorable premium.
Premium Brands and Stampede Culinary Partners: Premium Brands, based in British Columbia, closed its acquisition of Stampede Culinary Partners (based in Illinois, with operations in Calgary) for $688 million USD. This transaction highlights the trend of companies diversifying supply chains and creating “natural hedges” against market volatility.

The Impact of Artificial Intelligence (AI) on M&A

Artificial Intelligence is rapidly transforming both the flow and execution of M&A transactions. Nearly half of all strategic tech deals valued over $500 million involve an AI target or have an AI rationale. Over 75% of acquirers now assess the potential impact of AI when evaluating a transaction.

AI Applications in M&A:

Deal Sourcing: Identifying potential acquisition targets using AI-powered data analysis.
Due Diligence: Automating data analysis and identifying potential risks and opportunities.
Business Intelligence: Leveraging AI to gain deeper insights into market trends and competitor strategies.
Data Analytics: Utilizing machine learning to analyze large datasets and identify patterns.

However, Mackenzie Regent emphasized that AI is still in its early stages of adoption. While AI and machine learning can automate repetitive tasks, the need for human expertise remains crucial. “Past doesn’t necessarily equal future,” she stated, highlighting the importance of professionals who can interpret AI-generated data and provide nuanced insights. The human perspective is essential for understanding the broader implications of data and making informed decisions.

Future Outlook & Key Takeaways

The discussion suggests that the M&A momentum observed in 2025 is likely to continue into 2026, albeit with a continued emphasis on navigating uncertainty. Companies are increasingly willing to pursue deals despite market volatility, utilizing sophisticated structuring techniques and leveraging the power of AI. However, the human element – particularly in business valuation and strategic interpretation – will remain critical for successful dealmaking.

The key takeaway is that M&A is no longer about waiting for perfect conditions; it’s about proactively adapting to a constantly changing landscape and deploying capital strategically.
