US M&A deals of the week: 18 July 2025

Chevron’s $55bn Hess close led this week’s US dealflow. A surge of high-value US transactions defined the week, from Chevron’s landmark offshore energy win to Walgreens’ historic exit from public markets and a string of debt-financed acquisitions spanning healthcare, energy, and real estate.








This week’s US M&A activity showcases a decisive shift toward future-focused, resilience-driven strategy across sectors. In energy, Chevron’s long-fought acquisition of Hess underlines the majors’ reorientation toward durable offshore plays — particularly as global supply chains rewire and energy security becomes a core investor theme. Guyana’s Stabroek block, where Chevron now joins Exxon and CNOOC, is emblematic of this: high-yield, low-cost barrels in geopolitically stable jurisdictions are commanding long-term premiums.

Meanwhile, Walgreens’ exit from public markets reflects a different strategic undercurrent: private equity’s deepening reach into legacy businesses where public turnaround patience has run thin. Sycamore’s move echoes a broader PE trend — taking mature but struggling enterprises private for radical, sometimes controversial restructurings out of the spotlight. Analysts and regulators alike will watch closely how its operational playbook unfolds.

Sanofi’s Blueprint buy highlights big pharma’s sharpening race for post-patent resilience. With Dupixent’s exclusivity window narrowing, acquisitions like Ayvakit’s pipeline are less about synergy and more about pipeline replacement — a theme likely to accelerate in H2.

Finally, the Talen and Starwood deals both point to infrastructure plays responding to AI’s real-world demands. Data centre energy loads are already reshaping US power dynamics — and institutional capital is shifting accordingly. Starwood’s pivot toward long-duration net lease assets, and Talen’s aggressive CCGT expansion, both signal a redefinition of “defensive” in the age of always-on, always-learning computing.

As interest rate expectations stabilise and 2026 political cycles near, dealmakers appear increasingly willing to pull the trigger on strategic bets — even amid regulatory unknowns.

  • Mega-deals are back as legal and regulatory headwinds clear. Chevron and Sycamore’s landmark transactions show that strategic buyers are willing to move decisively once prolonged uncertainties — arbitration, shareholder approval — are resolved.
  • Private capital is reshaping legacy industries out of public view. Walgreens’ take-private underscores private equity’s growing role in turnaround plays where public patience has worn thin.
  • Infrastructure-linked energy is drawing fast capital. Talen’s and Starwood’s moves reflect investor appetite for high-yield, durable assets tied to AI-driven demand and energy system resilience.
