Mergers and acquisitions are seeing a rise after a stretch of uncertainty. Over the past few years, deal-making took a massive hit, all thanks to geopolitical tensions, economic fluctuations, and the lingering effects of the pandemic.

Companies are shifting gears, and we are starting to see a real comeback across the market. Businesses across industries like healthcare, technology, and financial services are returning to the game, increasing their M&A activity to grow, innovate, and stay competitive in an ever-changing market. Additionally, we are witnessing a new era of deal activity resulting from new technologies, more access to capital, and enhanced deal sourcing.

This blog will explore the most significant and upcoming M&A deals of 2025 and major mergers or acquisitions that have already made waves this year.

1. ConocoPhillips Acquisition of Marathon Oil

• Projected Date: Q4 2024 - Early 2025
• Value: $22.5 billion
• Industry: Energy

This deal between ConocoPhillips and Marathon Oil is set to become one of the largest M&A deals in 2024. With oil prices remaining high, ConocoPhillips plans to secure more assets in the Permian Basin, a critical region for U.S. oil production. Given both companies' solid financial positions and strategic fit, this deal will likely go through.

Significant operational synergies are expected to allow ConocoPhillips to seamlessly integrate Marathon Oil’s assets into its existing operations. This would eventually benefit the combined entity through enhanced efficiency and a more assertive position in the energy sector.

2. Swisscom Acquisition of Vodafone Italia

• Projected Date: Q1 2025
• Value: $8.6 billion
• Industry: Telecommunications

Swisscom’s plan to acquire Vodafone Italia is among the most talked-about acquisitions in the European telecom market. They’ll create Italy’s second-largest broadband operator by merging Vodafone Italia with Fastweb, a Swisscom subsidiary. Although the rationale behind the merger is quite substantial, the likelihood of this deal being completed is moderate, given Europe's expected regulatory scrutiny.

If this deal goes through, Swisscom will significantly expand its footprint in Italy, and the combined entity will have a stronger competitive position in the market. Both would benefit from the increased scale and cost efficiency, making them formidable players in the European telecommunications market.

3. Permira Acquisition of Squarespace

• Projected Date: Q4 2024 - Early 2025

• Value: $6.9 billion
• Industry: Tech

In this all-cash deal, Private equity firm(PE firm) Permira is set to take Squarespace private by capitalizing on the current valuations within the tech sector. Given the strategic benefits of Squarespace and Permira’s strong financial backing, this deal will likely close. This is one of the broader trends in which a private equity firm seizes the opportunity in the tech sector.

Further, this acquisition is expected to provide Squarespace with the much-needed flexibility to innovate and grow without the pressures of the public market. This, in turn, would enhance its ability to play in the crowded digital platform space, leveraging new technologies and keeping its focus on long-term growth.

4. CPP Investments & GIP Acquisition of Allete

• Projected Date: Q2 2025
• Value: $6.2 billion
• Industry: Energy

Allete’s acquisition by CPP Investments and Global Infrastructure Partners (GIP) is a highly-anticipated move for the energy sector, reflecting a shifted focus on investments in renewable energy and its infrastructure. The likelihood of the deal’s closure is high, given that it is driven by two major investment firms with strong financial positions.

By taking Allete private,  CPP Investments and GIP can provide the capital needed for the company to expand its portfolio, particularly in sustainable energy projects.

5. T-Mobile Acquisition of US Cellular

• Projected Date: Q2 2025
• Value: $4.4 billion

T-Mobile's acquisition of a significant portion of US Cellular's wireless spectrum is a smart move to enhance its network coverage, specifically for geographically isolated areas in the U.S. Though we expect some regulatory scrutiny, the likelihood of a final deal is moderate to high.
