The Asia M&A Rankings 2026, published by ALB, highlights the region’s leading M&A law firms amidst a market that has shown both resilience and vulnerability in the first half of 2026. According to ION Analytics’ Mergermarket data, Asia-Pacific M&A generated 5,171 deals worth $490 billion in H1 2026, an 11 percent decline in volume and a 23.9 percent drop in aggregate value year-on-year.
This downturn makes Asia-Pacific the sole major region where both deal volume and value decreased in H1 2026. The primary factors include geopolitical instability, energy market volatility, and growing disparities between high-performing and struggling economies. Analysts at Mergermarket noted that while the region started 2026 with strong momentum, the Iran conflict—especially disruptions in the Strait of Hormuz—severely impacted its outlook.
Regional Divergence
Despite the aggregate decline, there is a revealing divergence within the region. A&O Shearman noted that Asia-Pacific M&A slowed sharply in H1 2026, but strong activity in Japan and Australia showed that dealmakers continued to find opportunities despite energy disruption, tariff pressure, and shifting regulatory regimes. Japan and Southeast Asia accelerated even as the wider region contracted, while the Chinese mainland and Hong Kong cooled sharply.
PwC’s mid-year outlook captured the paradox at the regional level: Asia-Pacific’s share of global deal volume rose to 37 percent, supported by activity in China, Japan, and parts of Southeast Asia, but its share of deal value fell to 16 percent, reflecting fewer megadeals and smaller average transaction sizes than in the Americas and EMEA.
Resilient Japan
Japan has maintained a streak of record-breaking M&A activity, supported by corporate governance reforms, increased shareholder activism, and greater acceptance of private equity investments.

Japan’s performance in H1 2026 was strong, with M&A value exceeding $84 billion, up 25 percent from the previous six months, while volume rose 7 percent. Inbound M&A reached $15.1 billion across 109 transactions, placing Japan just outside the world’s ten most-targeted markets. Private equity’s role in this expansion has become structural rather than opportunistic, driven by Tokyo Stock Exchange rules on capital-efficiency disclosures.
Activism has scaled alongside deal flow, with Japan remaining Asia’s activism hotspot, accounting for 56 percent of regional activity in 2025 and 32 percent in Q1 2026. Activists won 37 board seats at Japan-based companies in 2025, up from seven in 2024 and 23 in 2023.
The Japanese government’s regulatory infrastructure continues to evolve, with tender offer rules effective from May 1, 2026, lowering the principal threshold for mandatory tender offers from one-third to 30 percent. This change has led to an increase in contested approaches, with unsolicited tender offers rising from four in 2024 to seven in 2025.
In April 2026, Japan’s government advised against a $1.8 billion takeover of Makino Milling Machine by an MBK Partners affiliate, citing national security concerns under the Foreign Exchange and Foreign Trade Act. The move shows that while Japan has opened its markets, certain strategic sectors remain off-limits to foreign investors.
According to Mergermarket, Japan’s M&A market is expected to continue its strong performance, driven by governance reforms, activist pressure, and the growing acceptance of private equity. The country’s regulatory infrastructure will play a significant role in shaping the market, with changes such as the revised tender offer rules and the increasing importance of national-security considerations.

Singapore cemented its position as the regional hub, accounting for $33 billion across 165 deals in H1 2026, nearly double the $16.7 billion recorded a year earlier. Private equity was especially active at the start of 2026, with EY-Parthenon finding that Southeast Asia recorded 19 private equity-backed investments worth $9.2 billion in Q1.
India’s M&A Market
India produced the largest transaction recorded in Asia-Pacific in H1 2026, with Vedanta’s $20.7 billion five-way demerger. The restructuring separated the mining-to-metals conglomerate into five listed entities spanning aluminium, oil and gas, iron and steel, power and the residual Vedanta business.
Beyond that transaction, India’s M&A market sustained momentum, with Conyers finding that, from September 2025 through February 2026, India completed just over 500 M&A deals with an aggregate reported value of $30.8 billion. Activity was diversified across technology, real estate development, and consumer goods and services.
EY reported that India’s M&A value reached $123.8 billion in 2025, up 18 percent year-on-year, even as volume declined 3 percent. Momentum continued into 2026 through insolvency resolutions and stake sales, including Adani Enterprises’ proposed acquisition of Jaiprakash Associates under India’s insolvency process, which remained subject to appellate proceedings during the first half of 2026, with a deal value of $3.7 billion.
