Compared with the prior week, overall deal activity edged lower, with announced volumes declining 3% from 708 transactions, while total deal value fell more sharply by 48%, down from USD 121.11 billion, reflecting the absence of a mega-cap transaction comparable to the prior week.

Deal No. 1:
International Business Machines Corporation to Acquire Confluent, Inc. for USD 11.00 Billion
IBM has agreed to acquire data infrastructure specialist Confluent in an all-cash transaction valued at USD 11 billion, equivalent to USD 31 per share. The acquisition strengthens IBM’s position across artificial intelligence and data management, where real-time data availability is increasingly critical to scalable AI deployment.
Confluent develops a cloud-native data streaming platform based on Apache Kafka that allows enterprises to continuously capture, process, and distribute data across applications and environments. Its technology enables real-time analytics, event-driven workflows, and operational monitoring, addressing data fragmentation challenges that increasingly constrain agentic and AI-based systems. Over the past four years, Confluent’s total addressable market has expanded significantly, doubling from approximately USD 50 billion to USD 100 billion by 2025, reflecting growing demand for real-time data infrastructure.
The acquisition aligns closely with IBM’s hybrid cloud and AI strategy. By combining Confluent’s real-time data streaming capabilities with IBM’s AI infrastructure software and automation portfolio, the group is positioned to deliver more integrated, end-to-end solutions for enterprises seeking to operationalize AI at scale.
The transaction is expected to generate meaningful product and commercial synergies, with IBM’s global go-to-market platform providing an avenue to accelerate adoption and revenue growth across Confluent’s offerings.
Completion of the transaction is targeted for mid-2026, subject to customary regulatory approvals and closing conditions.
Deal No. 2:
Minmetals Property Holding Co Ltd. to Acquire MCC Real Estate Group Co., Ltd. for USD 4.42 Billion
Metallurgical Corporation of China (MCC) is undertaking a portfolio realignment by exiting its real estate business, selling its entire equity interest in MCC Real Estate to China Minmetals for CNY 31.2 billion (USD 4.42 billion). The transaction reflects MCC’s decision to concentrate resources on its primary engineering and metallurgical construction activities.
MCC Real Estate operates as MCC’s real estate development platform, undertaking large-scale urban projects that include residential communities, commercial complexes, and industrial parks. The business combines property development with infrastructure delivery by drawing on MCC’s engineering capabilities, with many projects linked to urban regeneration and mixed-use developments across China.
Separately, Minmetals will acquire MCC’s full equity interests in China ENFI Engineering, MCC Copper and Zinc, and Ramu Nico Management MCC, as well as a 67% stake in MCC Metallurgical and Chemical, for an aggregate consideration of CNY 29.4 billion (USD 4.2 billion).
Proceeds from the divestments will be directed toward reinforcing MCC’s core metallurgical construction franchise, supporting new industrialization and urbanization initiatives, and accelerating investment in engineering services, advanced materials, and high-end equipment manufacturing.
China Minmetals, a state-owned metals and mining group, is MCC’s controlling shareholder. Upon completion of the transactions, MCC’s position within the Minmetals group is expected to become more clearly defined, with a streamlined mandate centered on engineering contracting and specialized industrial services.
Deal No. 3:
Antero Resources Corporation to Acquire Upstream Assets of HG Energy II, LLC. for USD 2.80 Billion
Antero Resources is acquiring HG Energy’s upstream Marcellus shale assets in West Virginia in an all-cash transaction valued at USD 2.8 billion. The acquisition expands Antero’s core operating footprint and reinforces its position as a liquids-focused developer in the Marcellus.
The acquisition covers roughly 385,000 net acres located adjacent to Antero’s existing 475,000 net acres in the core Marcellus. The assets are expected to contribute approximately 850 MMcfe per day of production in 2026 and include more than 400 undeveloped drilling locations, around three-quarters of which are liquids-rich and immediately viable within Antero’s capital program.
In addition to adding scale, the assets are expected to improve Antero’s long-term capital efficiency and provide greater flexibility to direct dry gas volumes toward increasing regional demand, particularly from data center development and gas-fired power generation.
The transaction is expected to close in the second quarter of 2026. RBC Capital Markets is advising Antero Resources on the transaction, while Jefferies is acting as financial advisor to HG Energy.
Deal No. 4:
Ageas SA/NV to Acquire AG Insurance SA/NV for USD 2.30 Billion
Ageas is acquiring the remaining 25% interest in AG Insurance from BNP Paribas for EUR 1.9 billion (USD 2.3 billion), resulting in full ownership of its Belgian insurance subsidiary. The transaction simplifies Ageas’s group structure and increases its exposure to one of its most stable and cash-generative businesses.
AG Insurance is Belgium’s largest insurer, holding the top position across both life and non-life segments. The company distributes its products primarily through a long-established bancassurance arrangement with BNP Paribas Fortis, supported by an extensive network of independent brokers, providing broad and resilient market access. As a key operating entity within the Ageas group, AG Insurance combines scale in its home market with a diversified product mix and a focus on sustainable earnings.
The acquisition supports Ageas’s Elevate27 strategy, which prioritises inorganic growth in fully consolidated, capital-efficient businesses with strong cash generation. Management expects the transaction to contribute positively toward the group’s Elevate27 financial objectives while preserving a solid capital position following completion.
In parallel, Ageas and BNP Paribas have reaffirmed their long-term bancassurance partnership in Belgium and formalized BNP Paribas’s role as a shareholder in Ageas, reinforcing the strategic relationship between the two groups.
The transaction is expected to be completed in the second quarter of 2026.

Blackstone Real Estate Advisors L.P.; Divco West Real Estate Services, LLC; MW Group, Ltd. to Acquire Alexander & Baldwin, Inc. for USD 2.30 Billion
Alexander & Baldwin (A&B), a Hawaii-based commercial real estate owner, is being taken private in a USD 2.3 billion transaction led by a consortium comprising MW Group, Blackstone Real Estate, and DivcoWest. The deal transitions the company from public ownership while maintaining its long-term focus on essential retail assets in Hawai‘i.
A&B owns the state’s largest portfolio of grocery-anchored neighborhood shopping centers, alongside a diversified base of industrial and office properties. Its holdings total roughly 4.0 million square feet of commercial space, spanning 21 retail centers, 14 industrial assets, and four office properties, in addition to fee interests covering approximately 146 acres of ground lease land.
Following the acquisition, A&B will continue operating under its existing name and brand, with its headquarters remaining in Honolulu and leadership retained under a locally based management team. The investor group has also committed over USD 100 million toward capital improvements across the portfolio.
Transitioning to private ownership is expected to provide greater strategic and financial flexibility, enabling the company to invest more actively in its assets and better support tenants and local communities.
The transaction is expected to close in the first quarter of 2026. Upon completion, A&B’s shares will be delisted from the New York Stock Exchange. BofA Securities is acting as exclusive financial advisor to A&B, while Wells Fargo and Eastdil Secured are advising Blackstone.
