Why global M&A deals collapsed in 2025: Inside the hostile bids, cultural resistance, and execution risks that reshaped dealmaking

Banco Bilbao Vizcaya Argentaria SA (BBVA), RedBird Capital Partners, and Kohlberg Kravis Roberts & Co. (KKR) were among the global financial players that saw high-profile transactions collapse in 2025. While total global M&A value climbed, the volume of completed deals fell sharply, signaling a rising gap between strategic intent and execution capability. From shareholder rejection to editorial pushback and regulatory overhang, failed bids this year revealed the new risk factors governing complex mergers across finance, media, and infrastructure.

According to PricewaterhouseCoopers, global deal value rose in the first half of 2025, but total M&A volume declined by 9 percent. That divergence underscored a fundamental tension: even as liquidity returned to markets, the path to closing deals became more complicated. Stakeholder alignment, political optics, and regulatory timing now pose execution hurdles comparable to capital constraints. Failed takeovers such as BBVA’s all-stock offer for Banco Sabadell and RedBird Capital’s attempted acquisition of Telegraph Media Group illustrate the fragility of large-scale strategic bets in today’s deal environment.

Why did BBVA’s €16.3 billion bid for Banco Sabadell collapse despite banking consolidation logic?

Banco Bilbao Vizcaya Argentaria SA spent more than a year positioning itself to acquire Banco Sabadell SA in a €16.3 billion hostile takeover effort aimed at consolidating the Spanish banking sector. The strategic logic was rooted in cost synergies, branch rationalization, and European balance sheet scale. However, the bid failed to secure shareholder support, with only 25.47 percent of Sabadell’s voting rights tendered—well below the 50 percent needed for approval.

BBVA’s proposal faced multiple headwinds. Sabadell’s board opposed the offer early on, citing undervaluation and execution complexity. Meanwhile, activist shareholder engagement on both sides signaled that the premium offered failed to reflect Sabadell’s underlying value in a rising interest rate environment. As BBVA’s bid turned hostile, reputational and political risks mounted. By October 2025, BBVA confirmed it would not extend or revise the offer. The bank’s chairman announced he would stay on despite the failed bid, and BBVA shares rose modestly following the withdrawal.

The collapse serves as a cautionary tale about the limits of scale-driven M&A when target shareholders remain unconvinced of valuation fairness or integration credibility. It also showed that hostile bids in regulated sectors like banking can trigger unintended reputational consequences, especially when key domestic institutions are involved.

What triggered RedBird Capital’s decision to withdraw its Telegraph Media Group acquisition?

RedBird Capital Partners’ planned acquisition of Telegraph Media Group in the United Kingdom was one of the most closely watched private equity–media deals of the year. Valued at approximately £500 million, the bid was expected to result in major operational restructuring and content platform expansion. But the transaction collapsed in November 2025 after newsroom leaders and editorial staff publicly opposed the sale, citing concerns over independence and cultural dilution.

RedBird’s withdrawal reflects a broader lesson for investors eyeing legacy media brands: intangible assets such as editorial trust and institutional continuity can become deal-breaking variables. The proposed transaction faced scrutiny not just from employees, but from parliamentary committees concerned about media plurality and foreign ownership. While RedBird maintained that its interest was commercially motivated, political and cultural resistance hardened over time.

The deal’s failure also underscored the challenges of structuring cross-border media investments in markets with highly localized political ecosystems. Private equity interest in media will likely remain strong, but RedBird’s retreat suggests future buyers must engage in stakeholder mapping far earlier in the transaction lifecycle.

Why did KKR walk away from Thames Water despite preferred bidder status?

In the United Kingdom’s infrastructure sector, Kohlberg Kravis Roberts & Co. was designated the preferred bidder to acquire Thames Water, the country’s largest water utility, in mid-2025. At the time, Thames Water was facing severe liquidity pressures and mounting regulatory scrutiny. The company’s complex capital structure and public service obligations made it a difficult asset to value—and even harder to restructure.

Despite early momentum, KKR pulled out of the deal before completing due diligence, citing execution risks linked to government intervention, regulatory delays, and public opposition. The transaction was further complicated by media coverage around environmental violations and customer dissatisfaction, which made political oversight unavoidable.

KKR’s exit from the Thames Water process demonstrates the volatility of regulated utility acquisitions in periods of public distrust and fiscal fragility. The firm’s decision to walk away, despite initial frontrunner status, shows how even experienced infrastructure investors are reassessing risk appetite in markets with high regulatory complexity and limited price flexibility.

Across markets, 2025 exposed the limitations of headline M&A value as an indicator of dealmaking health. While the total dollar volume of announced deals increased, fewer transactions reached the finish line. In part, this reflected tighter regulatory timelines, especially in cross-border combinations involving sensitive sectors like finance, media, defense, and critical infrastructure.

Antitrust regulators in the United States and European Union continued to push back against consolidation, using broader definitions of competitive harm that include innovation effects and labor market impacts. Foreign investment review boards from Canada to India also expanded oversight, lengthening approval windows and raising strategic barriers to entry.

In parallel, shareholders became more vocal. Institutional investors, particularly pension funds and ESG-aligned asset managers, rejected deals that lacked clear post-merger integration plans or presented reputational risks. Hostile offers were particularly prone to failure unless bidders could show overwhelming support and political neutrality.

In media and consumer-facing sectors, stakeholder sentiment increasingly included internal employee groups and civil society organizations. These new gatekeepers can shape political perception and influence regulatory posture, particularly in high-profile or symbolic transactions.

What signals should 2026 dealmakers take from 2025’s collapsed bids?

The global wave of failed bids in 2025 offers a strategic checklist for corporate development teams, investment banks, and private equity firms preparing for the next cycle. Execution readiness now rivals financial preparation in importance. Deals must be structured to anticipate multi-jurisdictional regulatory friction, shareholder activism, and shifting political optics.

This means pre-wiring regulatory dialogues, engaging with activist investors early, and building stakeholder outreach into the term sheet phase. Traditional reliance on fairness opinions and synergy models no longer guarantees board or investor support. Transactions need robust internal communications plans, ESG narratives, and public signaling strategies to avoid misfires.

Dealmakers who fail to adapt may continue to burn capital on abandoned negotiations, while those who build execution flexibility and narrative foresight into their playbooks will have a durable advantage in an increasingly contested M&A arena.

  • BBVA’s €16.3 billion bid for Banco Sabadell collapsed after failing to secure shareholder acceptance, highlighting the limitations of hostile offers in regulated markets.

  • Regulatory complexity in the United States, European Union, and Asia significantly delayed or deterred strategic mergers, particularly those involving cross-border players.
  • Institutional investors increasingly rejected deals with unclear integration paths or weak ESG frameworks, raising the bar for board-level approval.
