10 M&A Rumors You Should Be Watching
May 2026 Global M&A Tracker - Deal Rumors
The rumor mill ran hot in May 2026. Across sectors and geographies, whispers of consolidation, unsolicited bids, and strategic pivots made headlines. In several cases they moved stock prices sharply. Below, we break down ten of the most compelling deal rumors from last month, all involving publicly traded equities, and explain why each one matters to investors.
1. GameStop Bids for eBay — And Gets Rejected
Target: eBay Inc. (NASDAQ: EBAY) Rumored Acquiror: GameStop Corporation (NYSE: GME) Rumored Value: ~$56 billion ($125 per share, 50% cash / 50% stock) Status: Informal offer — rejected by eBay board
This was the most jaw-dropping proposal of the month. GameStop (the meme-stock retailer turned bitcoin treasury holder) submitted an unsolicited, non-binding bid to acquire eBay at $125 per share on May 3. The offer represented a roughly 20% premium to eBay’s prior closing price and valued the e-commerce marketplace at approximately $56 billion. GameStop had quietly built a ~5% economic stake in eBay through derivatives and common stock, and secured a $20 billion debt commitment from TD Bank to help fund the deal.
eBay’s board moved quickly: on May 12 it rejected the proposal outright, calling it “neither credible nor attractive” and citing concerns around financing certainty and the debt burden the transaction would impose. GameStop CEO Ryan Cohen confirmed the company’s intent in a combative CNBC appearance, but without board support from the target, the bid has gone nowhere.
Why it matters for investors: The episode is a Rorschach test. Bulls on GME see it as evidence that Cohen is deploying the company’s $4+ billion cash pile aggressively, pursuing scale through acquisition rather than waiting for organic growth. Bears see a retailer with no core business making a moonshot bid for an asset four times its size. For eBay holders, the 20% bid premium already evaporated after the rejection. But the episode raised a legitimate question: is eBay undervalued, and will a more credible suitor come along?
2. Legal & General: Multiple Bidders Quietly Circling the FTSE 100 Giant
Target: Legal & General Group plc (LSE: LGEN) Rumored Acquirors: Multiple unnamed financial institutions and alternative asset managers Rumored Value: ~$18.9 billion (based on ~£13.9 billion market cap) Status: Rumor — CEO publicly denied
Legal & General, one of the UK’s largest financial services groups managing over £1 trillion in assets, became the subject of intense City chatter in mid-May. According to the Financial Times, a range of financial institutions had been evaluating potential approaches. The logic fits a well-worn playbook: firms like Apollo and Brookfield have been acquiring insurers to access their large, stable liabilities as a low-cost source of capital for private credit and alternatives deployment.
Chief Executive Antonio Simoes was emphatic in his denial, telling the FT he was “100% focused on executing my strategy” and not considering a sale or break-up. L&G shares nevertheless rose around 5% on the speculation.
Why it matters for investors: L&G sits at an interesting strategic crossroads. Its large pension risk transfer business and £1 trillion+ AUM make it an exceptional source of “patient capital” for an alternatives acquiror. A full takeover would be among the largest UK financial deals in history and it would be politically sensitive given L&G’s systemically significant role in UK gilt markets. More realistic near-term scenarios include partial stake sales, reinsurance partnerships, or carve-outs of specific business lines. Even without a deal, the speculation highlights that L&G’s parts may be worth considerably more than its whole.
3. Nordex Eyes Vestas to Build a European Wind Champion
Target: Vestas Wind Systems A/S (Nasdaq Copenhagen: VWS) Rumored Acquiror: Nordex SE (Frankfurt: NDX1) Rumored Value: ~$30 billion (based on Vestas market cap) Status: Rumor
On May 4, reports emerged that Germany’s Nordex SE was exploring a potential acquisition of or merger with Danish rival Vestas Wind Systems. The stated rationale is geopolitical as much as commercial: proponents argue that a combined entity would create a European wind turbine champion capable of countering the rapid rise of Chinese manufacturers and reduce European dependence on Asian supply chains (especially for offshore wind). Other names floated as potential consolidation candidates in the sector include Siemens Gamesa, GE Vernova, and privately held Enercon.
Why it matters for investors: The European wind turbine industry is under serious pressure. Vestas and Siemens Gamesa have both posted large losses in recent years amid cost inflation and supply chain disruptions, while Chinese competitors are undercutting on price in global markets. A Nordex-Vestas combination would create a manufacturer with genuinely global scale. However, there is serious potential execution risk. The two companies have overlapping product lines, different nationalities of ownership, and a combined entity would require significant restructuring. Watch for regulatory signals from Brussels, which has shown appetite for backing European industrial consolidation when framed around strategic sovereignty.
4. Uber Moves to Absorb Delivery Hero
Target: Delivery Hero SE (Frankfurt: DHER) Rumored Acquiror: Uber Technologies Inc. (NYSE: UBER) Rumored Value: ~$11.6 billion (€33 per share) Status: Active — formal offer received, Delivery Hero conducting strategic review
This is perhaps the most advanced rumor on the list. Uber, which had already accumulated a ~19.5% stake in Delivery Hero, formally offered €33 per share for the remaining equity in late May. This implies a full company valuation of approximately €10 billion ($11.6 billion). Since then, Uber has continued building its position, purchasing Aspex Management’s stake to bring its total holding to 36.83%.
Delivery Hero operates food and quick commerce delivery across 70+ markets in Europe, the Middle East, Asia, and Latin America. They confirmed receipt of the offer and are evaluating it through a formal strategic review process.
Why it matters for investors: For Uber, Delivery Hero would dramatically expand its global delivery footprint beyond Uber Eats’ existing markets, particularly in high-growth emerging markets. It would also help Uber compete against DoorDash internationally. For Delivery Hero shareholders, the offer represents a potential exit from a business that has struggled to achieve sustained profitability. Given Uber’s growing ownership position, a deal appears more likely than not. The key questions are price and timing. Any bump above €33/share would materially benefit remaining minority holders.
5. Sherwin-Williams and Nippon Paint Make a Joint Raid on AkzoNobel
Target: Akzo Nobel NV (Euronext Amsterdam: AKZA) Rumored Acquirors: The Sherwin-Williams Company (NYSE: SHW) and Nippon Paint Holdings (TSE: 4612) Rumored Value: ~$10.5 billion (indicative offer of €73 per share) Status: Rumor — joint proposal confirmed then abandoned (June 3)
In one of the boldest tactical moves in the coatings industry in years, Sherwin-Williams and Nippon Paint jointly submitted an unsolicited all-cash proposal for AkzoNobel in late May, offering €73 per share. The proposal envisioned a split of the business: Nippon Paint would retain AkzoNobel’s Decorative Paints and Industrial Coatings divisions, while Sherwin-Williams would separately acquire Automotive & Specialty Coatings, Marine & Protective Coatings, and Powder Coatings.
AkzoNobel rejected the offer, citing insufficient deal certainty on regulatory clearances and business separation mechanics, and noting that the approach did not meet the “Superior Proposal” threshold under AkzoNobel’s existing merger agreement with Axalta Coating Systems. On June 3, Nippon Paint and Sherwin-Williams formally ended their pursuit.
Why it matters for investors: Even though the bid collapsed, the episode confirmed that AkzoNobel is a strategic prize coveted by two of the world’s largest coatings companies. The Axalta-AkzoNobel merger-of-equals (which both boards continue to recommend) now proceeds without a rival bidder. For Sherwin-Williams investors, the abandoned bid raises questions about what comes next for capital deployment. For Akzo Nobel holders, the key question is whether the Axalta deal creates comparable value to what Sherwin-Williams/Nippon Paint were offering in cash.
6. Intact Financial Explores a Bid for Hiscox
Target: Hiscox Ltd (LSE: HSX) Rumored Acquiror: Intact Financial Corporation (TSX: IFC) Rumored Value: ~$8.1 billion (based on £6.1 billion market cap) Status: Rumor — exploratory, no formal offer
On May 16, Insurance Post reported that Canada’s Intact Financial was exploring a potential bid for London-listed specialty insurer Hiscox. Hiscox shares surged as much as 15.3% intraday to an all-time high of £18.90 on the news. Intact CEO Charles Brindamour has publicly stated his ambition to expand in commercial lines and specialty insurance, and is said to be a longtime admirer of Hiscox’s business model.
No formal offer has been made, and neither company has commented publicly on the reports.
Why it matters for investors: Hiscox’s core business is specialty and commercial insurance for small businesses, high-net-worth individuals, and catastrophe reinsurance. It is a high-quality, capital-light franchise that has historically traded at premium multiples. Intact, already one of North America’s largest P&C insurers, would gain significant London market and Lloyd’s exposure through a deal. For Hiscox shareholders, the stock reaction itself is instructive: the 15% single-day spike suggests the market views current valuations as undemanding relative to a takeover scenario. Even if Intact walks away, a bid approach tends to put a stock “in play.”
7. Curium Pharma Targets Lantheus in a $7 Billion Radiopharmaceutical Play
Target: Lantheus Holdings Inc. (NASDAQ: LNTH) Rumored Acquiror: Curium LLC (Curium Pharma, private — portfolio company of CapVest Partners) Rumored Value: ~$7 billion Status: Rumor — Lantheus evaluating, active discussions reported
On May 22, reports emerged that Curium LLC, a leading nuclear medicine company backed by private equity firm CapVest Partners, had approached Lantheus Holdings with an acquisition proposal valuing the company at approximately $7 billion. Lantheus confirmed it was evaluating the proposal and considering strategic alternatives. Discussions are reported to be ongoing, with a deal potentially materializing within weeks. Lantheus shares rose approximately 7.4% on the news.
Lantheus is the maker of PYLARIFY, the leading prostate-specific membrane antigen (PSMA) PET imaging agent used in prostate cancer diagnosis, as well as other diagnostic imaging products.
Why it matters for investors: Radiopharmaceuticals are among the hottest segments in healthcare right now, sitting at the intersection of oncology diagnostics and targeted therapy. Lantheus’s PYLARIFY franchise is a market-leading product with strong volume growth as PSMA PET imaging becomes standard of care for prostate cancer. At $7 billion, Curium would be paying a significant premium for a high-growth asset, but one that arguably de-risks their pipeline and combines complementary commercial networks. For Lantheus shareholders, the key question is whether $7 billion adequately reflects the long-term value of PYLARIFY and the broader pipeline. Given recent deal multiples in the radiopharmaceutical space, some analysts believe a higher number is defensible.
8. ZIM’s Shipping Saga: A Rival Bid Complicates the Hapag-Lloyd Deal
Target: ZIM Integrated Shipping Services Ltd (NYSE: ZIM) Rumored Acquiror: Sakal Group and associated investors Rumored Value: $4.5 billion ($37.50 per share) Status: Rumor — rival bid to existing Hapag-Lloyd agreement
This is the M&A drama with the most twists. Hapag-Lloyd had already reached an agreement to acquire ZIM for $35 per share in an all-cash deal worth approximately $4.2 billion, and ZIM shareholders voted 97.36% in favor of the transaction on April 30. Then, on May 5, Israeli businessman Dany Sakal and a group of investors submitted a competing all-cash proposal at $37.50 per share, representing a 7.1% premium to the Hapag-Lloyd price and a 43.8% premium to where ZIM traded before the original deal was announced.
ZIM’s board, however, has stated the Hapag-Lloyd agreement is binding, leaving it no discretion to engage with the Sakal proposal. The deal also remains subject to approval from the State of Israel, which holds a “golden share” allowing it to block any sale deemed contrary to national strategic interests, which adds further geopolitical complexity.
Why it matters for investors: With shareholder approval already secured, the Hapag-Lloyd transaction is the most likely outcome. But the Israeli government’s golden share remains a genuine wildcard. If Israel were to block the Hapag-Lloyd deal on strategic grounds (maintaining Israeli ownership over the country’s flagship shipping line), the Sakal bid could re-emerge as the primary alternative. The $2.50/share spread between the two bids is meaningful: ZIM holders who tendered at $35 may be watching closely to see if Israeli regulatory dynamics force any renegotiation.
9. NSK and NTN to Merge, Creating the World’s Largest Bearing Maker
Target: NSK Ltd (TSE: 6471) Acquiror: NTN Corporation (TSE: 6472) Rumored Value: ~$4.3 billion (70% stake in NSK) Status: Informal / basic agreement announced — deal targeted for October 2027
Japan’s NSK and NTN, the world’s third- and fourth-largest bearing manufacturers respectively, announced a basic agreement in May to merge operations through a joint holding company to be established in October 2027 and listed on the Tokyo Stock Exchange Prime Market. Both companies would be delisted as part of the integration, with the combined entity expected to hold approximately 24% global market share, surpassing Sweden’s SKF (currently ~18%) to become the world’s number one.
The strategic drivers are clear: accelerating EV adoption is reducing demand for bearings used in internal combustion engines, while Chinese manufacturers are aggressively competing on price in global markets. Together, NSK (founded 1916) and NTN (founded 1918) employ nearly 50,000 people globally and generate combined revenues exceeding ¥1.7 trillion (~$10.9 billion).
Why it matters for investors: This is classic Japanese industrial consolidation and long telegraphed as necessary. For NSK and NTN shareholders, the merger promises synergies from combined R&D, manufacturing rationalization, and stronger pricing power vis-à-vis automotive OEM customers. The establishment of a new listed holding company creates a fresh investment vehicle in a sector undergoing significant structural change. The key risk is execution: merging two century-old Japanese manufacturers with deeply embedded cultures is a multi-year integration challenge that will test management at every level.
10. IMAX: Hollywood’s Favorite Premium Asset Goes on the Block
Target: IMAX Corporation (NASDAQ: IMAX) Rumored Acquirors: Multiple — including Apple, Sony, Netflix, Amazon, Disney, AMC, Cinemark, and Sphere Entertainment Rumored Value: ~$1.4 billion (based on CAD ~$1.9 billion market cap) Status: Rumor — IMAX reportedly fielding early-stage buyer interest
IMAX shares surged nearly 11% in late May after the Wall Street Journal reported the company was in the early stages of fielding potential buyers. CEO Rich Gelfond has previously told shareholders that IMAX is “an incredibly valuable player, either as a wholly differentiated publicly-traded company or as part of a larger company” (a comment that left the door conspicuously open). The company generated a record $1.28 billion at the global box office in 2025, up more than 40% year-over-year.
Potential acquirors span a wide range: theater chains like AMC and Cinemark are logical operators, while technology and streaming platforms such as Apple, Netflix and Amazon could use IMAX as a premium theatrical anchor for their broader content strategies. Sony and Disney have obvious content alignment motivations.
Why it matters for investors: IMAX is a rare asset: a globally recognized brand in premium entertainment with a capital-light licensing model, recurring revenue from system installations, and strong box office leverage. Its current valuation remains below pre-pandemic highs despite record box office performance and looks increasingly anomalous. In a consolidating media landscape where streaming giants are rethinking their theatrical relationships, IMAX represents an irreplaceable piece of the premium entertainment experience. A strategic acquiror could unlock significant synergies; for current shareholders, even a modest takeover premium would represent a meaningful re-rating from here.
