Close

Twenty announced M&A deals worth roughly $600 billion are still waiting to close as of August 2026. The largest pending acquisition is Paramount Skydance's $110billion takeover of Warner Bros. Discovery at $31.00 per share. The Justice Department cleared it in June 2026, but twelve state attorneys general sued to block it and trial is set for March 2, 2027. Union Pacific's merger with Norfolk Southern ranks second at $85 billion and has been held in abeyance by the Surface Transportation Board since May 2026. Charter and Cox, Boston Scientific and Penumbra, and Santander and Webster Financial are all awaiting final regulatory sign-off. This tracker lists every pending deal by value with its price basis, expected close date and the specific regulatory approval still outstanding.

Showing 44 of 44 deals. Pending deals are listed first, then closed deals, each ordered by value. Deal values are not comparable unless the basis matches, so each row states whether the figure is an enterprise value, an equity value or a per-share price, and flags carve-outs and press-reported figures. Where neither party disclosed a value, the row says so rather than showing an estimate. Announcement dates are shown for pending deals and closing dates for completed ones.

Deal volume will likely skew to fewer deals with larger price tags. Strategic buyers will focus on scale in areas that are difficult to organically grow, and sponsors will focus on quality in areas where public market pricing still offers room for value creation. Buyers will focus on targets that provide clear growth opportunities through the products they offer or control of critical infrastructure such as data centers and security.

Pending Deals

Upcoming M&A Deals: 20 Pending Transactions

Announced but not yet completed, ordered by deal value. Every figure is taken from the acquirer’s own release, an SEC filing or a regulator decision, with the basis stated.

  1. 1

    Paramount Skydance / Warner Bros. Discovery

    $110Benterprise value. $81B equity at $31.00 per share, all cash

    Cleared by DOJ, enjoined by agreementAnnounced Trial 2 Mar 2027Media & Entertainment

    The largest deal on the board, and the most stalled. Paramount is buying 100% of WBD for $31.00 a share in cash, funded with $47 billion of new Ellison family and RedBird equity plus $54 billion of debt. It is a 147% premium to WBD’s unaffected price of $12.54. Netflix had a signed agreement first, for Warner Bros. only after the Discovery Global spin-off at $82.7 billion enterprise value, but WBD’s board declared Paramount’s bid superior on 26 February and Netflix declined to raise. The deal has cleared the Justice Department, which closed its investigation in June 2026 without conditions, and the UK CMA cleared it on 6 August. Twelve state attorneys general and the Writers Guild are suing to block it, and Paramount has agreed not to close until five days after the verdict or 1 June 2027, whichever comes first. Ticking fees of $0.25 a share per quarter accrue in the meantime, roughly $650 million a quarter.

    Union Pacific / Norfolk Southern

    $85Benterprise value. NS holders receive 1.0 UNP share plus $88.82 cash

    Held in abeyance at the STBAnnounced Target mid-2027Freight Rail

    The first coast-to-coast freight railroad in the United States, connecting more than 50,000 route miles across 43 states and about 100 ports. The regulatory position is unusual and worth understanding precisely. The Surface Transportation Board found the original application incomplete in January 2026 because the railroads submitted 2023 market shares rather than forward-looking projections. It then accepted a revised application on 28 May 2026 but held the entire proceeding in abeyance, including the environmental review, pending supplemental filings across nine areas. Those filings landed on 27 July 2026 with four new shipper protections attached. No procedural schedule has been set for the rest of the case.

  3. 3

    Equity Residential / AvalonBay

    $69Bcombined enterprise value. Merger of equals, no purchase price

    Awaiting both shareholder votesAnnounced Expected H2 2026Real Estate

    An all-stock merger of equals creating one of the largest apartment landlords in the United States, with more than 180,000 rental units and a pro forma equity market capitalisation of about $52 billion. AvalonBay holders receive 2.793 Equity Residential shares each and end up with roughly 51.2% of the combined company against 48.8% for Equity Residential holders. Because it is a merger of equals there is no purchase price, so the $69 billion figure is the combined entity’s enterprise value. That is the only comparable number available and it should always be labelled as such.

  4. 4

    NextEra Energy / Dominion Energy

    Not disclosed0.8138 NextEra shares per Dominion share plus $360M aggregate cash

    Multi-regulator reviewAnnounced 12 to 18 monthsUtilities

    The largest regulated electric utility combination ever attempted. Neither company disclosed a transaction value, so the figures around $67 billion circulating in the trade press are derived calculations and should be attributed rather than stated as fact. Dominion holders receive a fixed 0.8138 NextEra shares each plus a one-time $360 million cash payment at closing, leaving NextEra holders with about 74.5% of the combined company. The approval list is the constraint: FERC, the Nuclear Regulatory Commission, the Virginia SCC, the North Carolina Utilities Commission, the South Carolina PSC, HSR and both shareholder votes. Virginia is the pressure point given how much data-centre load growth sits in Dominion’s territory.

  5. 5

    SpaceX / Cursor (Anysphere)

    ~$60Ball stock. Reported from an SEC filing, not a company release

    Customary closing conditionsAnnounced Guided to Q3 2026Technology / AI

    Announced four days after SpaceX’s IPO, this is a newly public company using its stock as acquisition currency almost immediately. Cursor’s AI coding platform slots into the compute and model stack SpaceX picked up when it acquired xAI in February 2026. Cursor had been raising at roughly a $50 billion valuation before the offer, against about $29 billion previously. One caveat for anyone citing the figure: the $60 billion has been reported from an SEC filing rather than a company release, so confirm the filing before presenting it as company-disclosed.

  6. 6

    McCormick / Unilever foods business

    $44.8Benterprise value at 13.8x FY2025 EBITDA

    Antitrust and shareholder approvalsAnnounced Expected mid-2027Food & Beverage

    McCormick is combining with Unilever’s foods arm in a deal valued at 13.8 times FY2025 EBITDA. Unilever receives $15.7 billion in cash plus stock representing 65.0% of the combined company, worth roughly $29.1 billion, which means the acquirer’s own shareholders end up in the minority. The mid-2027 close is a long runway even by consumer-staples standards.

  7. 7

    Charter Communications / Cox Communications

    $34.5Benterprise value for Cox

    FCC cleared, CPUC vote pendingAnnounced CPUC votes 13 Aug 2026Telecommunications

    Charter is combining with Cox in a transaction that values Cox at about $34.5 billion of enterprise value: $4 billion cash, $6 billion of convertible preferred units and roughly 33.6 million common units worth about $11.9 billion, leaving Cox Enterprises with about 23% of the combined company. The FCC’s Wireline Competition Bureau approved it on 27 February 2026 with conditions covering onshoring and a $20 an hour minimum wage. The last substantive step is the California Public Utilities Commission, scheduled to vote on 13 August 2026. A DOJ deadline of 15 September also looms: missing it triggers a refiling fee and a fresh 30-day waiting period.

    GIP and EQT consortium / AES

    $33.4Benterprise value. Equity value is $10.7B at $15.00 per share

    Stockholders approvedAnnounced Late 2026Energy / Power

    A consortium led by Global Infrastructure Partners (BlackRock) and EQT, with CalPERS and the Qatar Investment Authority alongside, is taking the power producer private at $15.00 a share. That is a 40.3% premium to the 30-day volume-weighted average price before 8 July 2025. The gap between the headline and the cheque is worth noting: enterprise value is $33.4 billion but equity value is only $10.7 billion, the difference being AES’s debt load. Stockholders have already approved.

    Bouygues, Iliad and Orange / SFR

    ~$23.4B€20.4 billion, split three ways

    Exclusive negotiations signedAnnounced EU review aheadTelecommunications

    France’s three remaining mobile operators are carving up the fourth. Bouygues Telecom, Free (Iliad) and Orange entered exclusive negotiations to split Altice France’s SFR between them, taking the French market from four national operators to three. Expect the most closely examined European telecoms review in years. Four-to-three consolidation is precisely the structure competition authorities have historically resisted.

    Fox Corporation / Roku

    $22Benterprise value at $160.00 per share

    Both shareholder votes requiredAnnounced Expected H1 2027Media / Streaming

    Fox is buying the streaming platform at $160.00 a share, made up of $96.00 in cash plus 0.9693 Fox Class A shares, leaving Fox holders with about 73% of the combined company. Two things a corporate development reader should notice. The premium is roughly 11% to the prior close, unusually thin for a deal this size and not disclosed in the release itself. And Roku has been trading around 16% below the offer price, which is the market pricing in real completion risk.

    $17.6Btake-private

    State gaming approvalsAnnounced PendingConsumer / Gaming

    Tilman Fertitta is taking the casino and hospitality operator private, consolidating two of the larger US gaming platforms under single ownership. Gaming regulators in every state where Caesars holds a licence need to approve the change of control, which is typically the slowest part of any transaction in this sector.

    Uber / Delivery Hero

    ~$14.8B€41.50 per share in cash, 100% basis

    BaFin, EU merger control, FDIAnnounced Expected H2 2027Technology / Delivery

    Uber is bidding €41.50 a share in cash for the German delivery group. The premium depends entirely on the reference you pick: 127% against the three-month volume-weighted average before 8 May, or 34% against the three-month average before announcement. Use the 34%. The larger number is measured to a pre-leak price. Uber has pre-wired the outcome, holding 24.77% outright plus instruments and irrevocables that take it to roughly 53% economic interest against a minimum acceptance of 50% plus one share. It has also pre-agreed the remedy: 14 overlapping markets worth about €11 billion of 2025 gross merchandise value go to SSW Partners for roughly €1.4 billion. Berlin headquarters and workforce are protected until at least 2029.

    Shareholders approved 6 May 2026Announced Expected H2 2026Healthcare / Med-tech

    The largest med-tech deal of 2026 and Boston Scientific’s entry into stroke and peripheral interventional. Penumbra holders can elect $374.00 in cash or 3.8721 Boston Scientific shares, with the mix landing around 73% cash. Penumbra stockholders approved on 6 May 2026 and antitrust clearance is the only gating item left. No premium was disclosed. Note the announcement date is January 2026, not 2023: the deal is sometimes misfiled to an earlier year.

    Nuveen / Schroders

    ~$13.5B£9.9 billion at 590p per share, all cash

    Court sanction and FCA approvalAnnounced Expected Q4 2026Financial Services

    TIAA’s investment arm is acquiring the British asset manager for 590p a share in cash plus permitted dividends of up to 22p, creating a platform of roughly $2.5 trillion in assets. That is a 29% premium to Schroders’ 456p close on 11 February, or 34% including the dividends. The structure is a court-sanctioned scheme of arrangement under Part 26 of the Companies Act. Shareholder risk is effectively retired: irrevocables cover about 42% of the share capital including the Schroder family trustees, and the 16 April meetings passed with 99.92% support. What remains is the court sanction hearing and FCA change-of-control approval.

    Martin Marietta / Lhoist North America

    $13.5Benterprise value at about 15x trailing adjusted EBITDA

    Antitrust clearanceAnnounced Expected H2 2026Materials

    Martin Marietta is paying $7.0 billion in cash and $6.5 billion in stock for the lime and industrial minerals business, at about 15 times trailing adjusted EBITDA including run-rate cost synergies. The company frames it as advancing its SOAR 2030 objective to expand its upstream Specialties segment. The governance detail worth flagging: the Berghmans family will hold roughly 15% of Martin Marietta on a fully diluted basis, with the right to appoint one director and one board observer.

    Fed approved 4 Aug 2026Announced Closing 20 Aug 2026Financial Services

    Santander’s push into US commercial banking, with a stated goal of 18% return on tangible equity in the US by 2028. This one is days from completion. The OCC approved on 12 June, the European Central Bank authorised it on 21 July and the Federal Reserve approved on 4 August, with closing now expected on 20 August 2026. Two drafting notes. Santander says $12.2 billion and Webster says $12.3 billion in their respective releases, so pick one and stay consistent. And neither party disclosed a premium to the prior close, only 16% to Webster’s 10-day volume-weighted average and more than 2.0 times tangible book value.

    Shareholder and regulatory approvalsAnnounced Expected early 2027Healthcare / Pharma

    India’s Sun Pharma is buying the Merck spin-off to build a global women’s health and biosimilars platform, in the largest deal in its history. Be careful with the premium. Organon’s own transaction deck markets a 103% premium, but that is measured to its 9 April closing price, seventeen days before announcement, during which the stock ran hard on deal speculation. The one-day premium to the Friday close before announcement is about 24%. Sun Pharma’s own release states no premium at all.

    The German group is paying $73.00 a share in cash to deepen its life-science tools portfolio. The disclosed 36% premium is measured to the one-month volume-weighted average rather than the prior close, so it should not be described as a premium to the last close.

    AbbVie is paying $135.11 a share in cash for the immunology biotech, a 49% premium to the prior close and one of the few 2026 biopharma deals to clear a 45% premium. The deal deepens AbbVie’s immunology portfolio ahead of Humira-era revenue erosion.

    $5.375Benterprise value for the carve-out division

    Foreign investment reviewAnnounced Expected H2 2026Industrial Robotics

    SoftBank is buying ABB’s robotics division, not ABB itself, in a carve-out valued at $5.375 billion of enterprise value. The division posted 2024 revenues of $2.3 billion, about 7% of ABB group revenue, with roughly 7,000 employees. ABB confirmed in its Q2 2026 report on 16 July that the sale is anticipated to complete in the second half of 2026. The often-repeated description of ABB as one of the robotics ‘Big 4’ appears in neither company’s release, so attribute it or leave it out.

Regulatory risk: how likely is each pending deal to actually close?

Not every announced megadeal closes. Below is DealRoom's risk read on each of the 20 pending deals as of Q2 2026 — assessed against the active regulatory dockets and public statements from the FTC, DOJ, FCC, CFIUS, and equivalent foreign authorities. Refreshed quarterly.

Regulatory risk: how likely is each pending deal to actually close?

Not every announced megadeal closes. Below is DealRoom's risk read on each of the 15 pending deals as of Q2 2026 — assessed against the active regulatory dockets and public statements from the FTC, DOJ, FCC, CFIUS, and equivalent foreign authorities. Refreshed quarterly.

Pending Deal Risk What's driving the rating
Netflix / Warner Bros. Discovery — $83B HIGH Combines the world's largest streaming platform with one of the largest Hollywood content libraries; expect 12-18 months of DOJ + FTC + EU review and likely consent decrees on content licensing or carriage terms.
PIF, Silver Lake, Affinity / Electronic Arts — $55B HIGH CFIUS review on Saudi Arabia's PIF taking a controlling stake in a major US gaming company; political risk on top of antitrust review.
Charter Communications / Cox Communications — $34.5B HIGH Active FCC review plus DOJ scrutiny on cable/broadband consolidation. Expected to require divestitures of overlapping franchise areas.
Cisco / Splunk (synergy realization) — $28B LOW Deal already closed; remaining "risk" is integration execution rather than regulatory.
Boston Scientific / Penumbra — $14.5B MEDIUM FTC review of med-tech consolidation in interventional vascular devices. No known major opposition; some product-line divestiture likely.
BlackRock / Global Infrastructure Partners — $12.5B LOW Asset-management consolidation rarely triggers material antitrust opposition; deal effectively complete in regulatory terms.
Apollo + Stone Point / Western Alliance — $11B HIGH Bank acquisitions require Federal Reserve and OCC approval. Post-2023 regional-banking stress means Fed scrutiny is elevated for any acquirer of a $50B+ bank.
Hg Capital / OneStream — $6.4B LOW PE buyout of a single enterprise-software vendor. Standard HSR review, no consolidation concerns.
SoftBank / DigitalBridge — $4B MEDIUM CFIUS review for foreign acquirer (SoftBank) in US data-center infrastructure; data-center assets increasingly classified as critical infrastructure.
Anthropic stake (rumored Google extension) — $4B HIGH Any further Google investment in Anthropic faces both DOJ AI-concentration scrutiny and ongoing search-monopoly remedy proceedings. Status remains rumored.
Sanofi / Dynavax Technologies — $2.2B LOW Small biotech bolt-on. Standard HSR; vaccines portfolio addition with no overlap concerns.
GSK / RAPT Therapeutics — $1.9B LOW Small biotech bolt-on. Standard HSR; clinical-stage asset acquisition.
Allegiant / Sun Country Airlines — $1.5B HIGH DOT airline merger review post Spirit-JetBlue blocking. Two ultra-low-cost carriers combining draws elevated DOJ scrutiny on consumer-pricing impact.
EGH / Hecate Energy — $1.2B LOW SPAC combination with a clean-energy developer; minimal antitrust concern.
Eli Lilly / Ventyx Biosciences — $1.2B LOW Small biotech bolt-on. Standard HSR; immunology pipeline addition.

Withdrawn and Blocked M&A Deals: Recent Cautionary Tales

Not every announced megadeal closes. Tracking withdrawn or blocked deals matters because the regulatory framework that killed them is the same framework that will be applied to today's pending mega-mergers - and the patterns repeat. Here are the most consequential failed announcements of the past three years, with the killer in each case.

Adobe / Figma - $20B (withdrawn December 2023)

Adobe abandoned its $20B Figma acquisition after 15 months of antitrust review by the UK CMA, EU Commission, and US DOJ all signaled they would block. Adobe paid Figma a $1B termination fee. Pattern to watch: any deal that combines a category leader with the strongest emerging challenger draws coordinated multi-jurisdiction review.

Spirit Airlines / JetBlue - $3.8B (blocked January 2024)

A federal judge blocked JetBlue's acquisition of Spirit on antitrust grounds, citing harm to ultra-low-cost-carrier competition and consumer pricing. Spirit subsequently filed for bankruptcy in November 2024. Pattern to watch: US DOJ now treats elimination of a pricing disruptor as standalone consumer harm - directly relevant to today's Allegiant / Sun Country pending deal.

Microsoft / Activision Blizzard - $69B (closed October 2023, but only after extended fight)

Closed eventually but only after the FTC sued, the UK CMA initially blocked, and Microsoft was forced to divest cloud-streaming rights to Ubisoft. Pattern to watch: mega-deals can survive opposition with structural concessions, but expect 18+ months and substantial divestitures - directly relevant to Netflix / WBD's pending review.

Tapestry / Capri (Coach + Michael Kors) - $8.5B (blocked, then abandoned 2024)

Federal court blocked the deal on antitrust grounds in October 2024; Tapestry abandoned the transaction the next month. Pattern to watch: luxury and fashion consolidation now subject to fresh competition-law scrutiny that didn't apply pre-2023.

Kroger / Albertsons - $24.6B (blocked September 2024)

Multiple federal and state courts blocked the supermarket merger; deal officially terminated December 2024. Pattern to watch: divestiture-as-fix proposals that rely on a smaller buyer (in this case C&S Wholesale) are now treated skeptically by courts as inadequate competitive remedies.

5 M&A Deals to Watch in 2026

Out of the 20 announced deals in our 2026-2027 tracker, five carry outsized strategic significance - either because of the size of the prize, the precedent the regulatory review will set, or the second-order effects on adjacent industries.

  1. Netflix / Warner Bros. Discovery - $83 billion. The single largest transaction on the 2026 board. If it closes, it creates the world's only true scale streaming-plus-Hollywood-library platform. If it's blocked or restructured, it locks in the current fragmented streaming landscape for another decade. The DOJ + EU review here will set the antitrust template for every follow-on streaming consolidation through 2030.
  2. PIF, Silver Lake, Affinity / Electronic Arts - $55 billion. The largest video-game acquisition in history, and the largest US tech acquisition by a Saudi-led consortium. The CFIUS review will signal how the US government treats sovereign-wealth-led acquisitions of major American IP-heavy companies - a precedent that affects pending deals across pharma, semiconductors, and consumer tech.
  3. Charter Communications / Cox Communications - $34.5 billion. Combines the #2 and #3 cable operators in the US. The FCC review will determine whether further cable consolidation is permissible at all - and the divestiture demands attached to any approval will reshape regional broadband competition for the next decade.
  4. Apollo + Stone Point / Western Alliance - $11 billion. The first major regional-bank acquisition since the 2023 stress. How the Federal Reserve approaches review here - speed, conditions, capital requirements - will dictate whether the broader regional-bank consolidation thesis materializes in 2026-2027 or stalls again.
  5. Boston Scientific / Penumbra - $14.5 billion. Tests whether mid-cap med-tech consolidation can clear FTC review without major divestiture. A clean approval here unlocks at least 5-7 follow-on med-tech deals on the back-burner; a contested review or block freezes that pipeline.

The rest of the 20-deal pipeline below is meaningful but more contained - pharma bolt-ons, software take-privates, and post-close synergy realizations rather than precedent-setting transactions.
