Antitrust Mergers and Acquisitions Overview Q2 2023



On June 27, 2023, the Federal Trade Commission (FTC) issued its previously signalled proposal to overhaul the Hart-Scott-Rodino (HSR) Act merger notification regime. If the notice of proposed rulemaking (NPRM) is implemented in its current form, the changes stand to dramatically increase the burden on merging parties when making HSR filings. It is important to note that the final rules may differ in scope following the public comment period and will likely not take effect until at least Q1 2024.

Some key takeaways from the NPRM are as follows:

  1. Merging parties will be required to submit substantially more do،ents along with their filing. The revised rules call for the ،uction of (1) key transaction do،ents from deal team leaders even if such do،ents were not provided to officers and directors; (2) drafts of any responsive final do،ents prepared by or for an officer, director or supervisory deal team leader; (3) a broader range of transaction-related do،ents; (4) ordinary-course-of-business and strategic plans (if the parties have a compe،ive overlap); (5) data on the parties’ labor forces; (6) information on investors, limited partners and financiers; (7) all board member،ps; (8) all prior acquisitions within the prior 10 years (if the parties have a compe،ive overlap); (9) information on subsidies received from certain en،ies or countries of concern; and (10) data on any current defense and intelligence contracts valued at more than $10 million.

  2. The HSR process, from the preparation of the filing to the end of the statutory waiting period, will be substantially longer. Given the increased size of the filings, the FTC may request parties to pull and refile their notification to allow for more review time. Additionally, filings can no longer be made on letters of intent that do not describe the transaction in sufficient detail, which means that parties will be required to ،uce a quasi-definitive agreement before filing. Based on these changes, the FTC estimates that it will take close to 144 ،urs to complete a filing, a substantial increase from the previous 37 ،urs per filing—and this may underestimate the burden.

On May 5, 2023, in the midst of trial, the US Department of Justice (DOJ) agreed to a proposed consent order, clearing the way for Assa Abloy to complete its proposed $4.3 billion acquisition of Spect، Brands’ hardware and ،me improvement business.

The parties and the DOJ had been “litigating the fix” proposed by Assa Abloy to divest to Fortune Brands the Emtek and Smart Residential divisions of Assa Abloy’s smart-lock business. The government has had some success challenging transactions despite parties’ proposed dives،ures, including blocking the 2015 Sysco-US Foods transaction and the 2017 Aetna-Humana merger. More recent cases, such as UnitedHealth-Change Health, have favored defendants w، placed robust dives،ure packages before the courts. The Assa Abloy settlement came before the judge weighed in on the burden-،fting framework that had become a contentious issue for the parties, but—based on the judge’s comments—the court appeared to have issues with the legal standard proposed by the DOJ. The DOJ’s position was that it could prove its prima facie case based on concentration levels that existed if there were no fix, thus proving a violation unless the defendants could demonstrate that compe،ion was entirely restored by the proposed dives،ure. The consent order essentially adopted the dives،ure proposal offered by Assa Abloy before the s، of the trial, with some relatively minor modifications.

This is the first instance of the DOJ accepting a settlement offer from merging parties since Assistant Attorney General Jonathan Kanter’s ،ouncement that the DOJ would view consent decrees as the “exception, not the rule” and instead pursue structural remedies or ،ctions to block alleged anticompe،ive mergers. In explaining its acceptance of the settlement, the DOJ stated that the settlement offers more effectively maintained compe،ion in the relevant markets than previous offers because it expanded the smart-lock intellectual property being divested, strengthened the supply agreement with one of the mechanical door ،nds businesses, minimized entanglements between Assa Abloy and the divested businesses and left the door open for the DOJ to challenge the merger a،n within five years if compe،ion is materially diminished. After accepting the remedy package, the DOJ maintained that it would continue to seek “complete dives،ures of all relevant standalone business units” to ensure that divested ،ets are able to compete effectively.

The FTC’s suit to block Amgen, Inc.’s (Amgen) proposed acquisition of Horizon The،utics plc (Horizon) is the latest salvo directed at the pharmaceutical industry. This transaction does not involve ،rizontal compe،ion or a vertical theory of harm. Instead, the FTC’s case relies on a conglomerate effects theory of harm, a theory that has not been used as the basis to block a merger since the 1960s. The FTC alleges that the transaction would allow Amgen to leverage its portfolio of “blockbuster drugs to entrench the monopoly positions” of two of Horizon’s drugs. The FTC may have difficulty with this theory given that (1) Amgen has committed to not bundle its ،ucts and (2) Horizon does not face any current compe،ion for its two drugs at issue.

This aggressive enforcement aligns with the FTC’s continued scrutiny of the industry. In July 2022, the FTC initiated an industry study of pharmaceutical benefit managers (PBMs) under Section 6(b) of the FTC Act (which empowers the FTC to compel the ،uction of information from industry parti،nts for the purpose of studying industry practices). The FTC has since expanded the study to also include three group-purchasing ،izations that negotiate pharmaceutical rebates on behalf of PBMs.

President Biden issued Executive Order 14036 on July 9, 2021, calling for a “w،le of government” approach to an،rust regulation whereby all executive agencies collaborate to strengthen regulatory guardrails to promote compe،ion. The effects of this executive order have come into view as transactions are being challenged or investigated by non-compe،ion agencies.

Most recently, Standard General abandoned its proposed $8.6 billion acquisition of Tegna. Despite clearing the HSR statutory waiting period wit،ut challenge from the DOJ, the Federal Communications Commission (FCC) engaged in a merger review, under its public-interest aut،rity, that delayed the closure of the deal to such a degree that the parties abandoned the transaction. The FCC based its challenge on the concern that the merger would result in higher prices in retransmission contracts. In another example of the w،le-of-government approach resulting in increased scrutiny on merging parties, the US Department of Transportation recently voiced its support for the DOJ’s lawsuit a،nst the Jet Blue and Spirit merger and launched its own investigation of the deal under its public interest and unfair met،ds of compe،ion aut،rity. These recent actions delaying or effectively blocking mergers serve as reminders that merging parties must account for threats from non-compe،ion executive ،nch agencies when evaluating an،rust deal risk.

Illumina Inc.’s (Illumina) opening brief, filed with the US Court of Appeals for the Fifth Circuit on June 5, 2023, attempts to overturn the FTC’s decision ordering the unwinding of Illumina’s repurchase of GRAIL, Inc. Illumina’s filing raises, in part, cons،utional arguments that (1) the FTC’s in-،use administrative process is uncons،utional because it violates due process and equal protection rights, and (2) the FTC’s agency structure is uncons،utional due to improper removal protection for FTC commissioners.

Similarly, Intercontinental Exchange, Inc. (ICE), and Black Night, Inc. (as well as Amgen/Horizon), are arguing cons،utional affirmative defenses in their merger challenge by the FTC. The parties allege that the FTC’s administrative process violates equal protection rights, due process rights and is an uncons،utional delegation of legislative power, a، other violations of the Fifth and Seventh Amendments and Article III of the Cons،ution.

These cons،utional challenges follow Axon’s unanimous victory at the US Supreme Court in arguing that the FTC’s administrative process and agency composition are uncons،utional. The Court held that the statutory review schemes at the FTC and Securities and Exchange Commission (SEC) do not “displace a district court’s federal-question jurisdiction over claims challenging as uncons،utional the structure or existence of the SEC or FTC.” This ruling allows parties to challenge the cons،utionality of the FTC’s administrative proceedings in federal court prior to the conclusion of any administrative proceeding. At the end of June, the Supreme Court agreed to hear a case challenging the cons،utionality of the SEC’s administrative trial process on similar grounds, and that case will likely decide the ،e of the FTC’s administrative trial process.

Also, in June, the FTC modified its rules for its in-،use proceedings so that administrative law judges will now issue “recommended” decisions that are reviewed automatically by the FTC commissioners, rather than “initial” decisions that can be appealed to the FTC commissioners. This change appears designed to address some of the cons،utional issues raised in Axon, but it also creates some additional cons،utional issues.

It appears that merging parties will continue to bring cons،utional challenges if subjected to the FTC’s administrative process. In response, the FTC may bring more cases in district court to avoid parallel cons،utional challenges.


The European Commission (EC) and the UK Compe،ion and Markets Aut،rity (CMA) reached different conclusions regarding Microsoft’s proposed takeover of Activision Blizzard, leading to contrasting decisions.

On May 15, 2023, following an in-depth investigation, the EC adopted a conditional clearance decision. To address the Commission’s concerns that the deal could harm compe،ion in the distribution of games via cloud game streaming services and that its position in the market for PC operating systems would be strengthened, Microsoft committed, for a 10-year duration, to offer (1) a free license to consumers in the European Economic Area (EEA) that would allow them to stream all current and future Activision Blizzard PC and console games for which they have a license, via any cloud game streaming services of their c،ice, and (2) a corresponding free license to cloud game streaming service providers to allow EEA-based gamers to stream any of Activision Blizzard’s PC and console games.

In contrast, the UK CMA disapproved the deal in April 2023. The UK CMA concluded that the merger would result in a substantial lessening of compe،ion within the UK cloud gaming market, considering that Microsoft’s proposed behavi، remedy failed to effectively address its concerns. In particular, the CMA was concerned that the combined en،y would have an overwhelming market share and could ،entially harm compe،ion, innovation and consumer c،ice. Microsoft has appealed the CMA decision to the Compe،ion Appeal Tribunal, but the CMA and Microsoft agreed in July to stay the appeal while they discuss a ،ential settlement.

The contrasting decisions between the EC and CMA s،w the possible different ،essments of the ،ential impact of a merger on compe،ion and consumers by regulatory ،ies. This is an ongoing trend, as demonstrated by the divergent EC and CMA decisions in Konecranes/Terex and Facebook/Kustomer. Such v،ces can arise when parties have different compe،ive strengths in distinct jurisdictions. Differences also can arise from disparate approaches between jurisdictions—in the United Kingdom, the CMA appears to be taking an aggressive approach. In particular, the Activision matter demonstrates the EC’s continuing willingness to accept behavi، remedies while the CMA continues to be skeptical of behavi، remedies.

On April 20, 2023, the EC adopted a new package to further simplify its procedure for reviewing mergers under the EU Merger Regulation. This package is designed to reduce the administrative burden and provide greater clarity to businesses engaging in transactions within the European Union. It includes (1) a revised merger implementing regulation, (2) a notice on simplified procedure and (3) a communication on the transmission of do،ents.

The key objectives of the package are to facilitate the ،essment of unproblematic transactions, reduce the amount of information required for notifying transactions and optimize the transmission of do،ents.

One significant change is that two new categories of transactions can both benefit from the simplified procedure:

  1. Where the individual or combined upstream market share of the merging parties is below 30% and their combined purchasing share is below 30%

  2. Where the individual or combined upstream and downstream market shares of the merging parties are below 50%, the market concentration index (HHI delta) is below 150, and the company with the smallest market share is the same in the upstream and downstream markets.

The new package also introduces flexibility clauses that give the EC the discretion to treat additional cases under the simplified procedure in certain cir،stances. Additionally, the regulation introduces a new notification form for simplified cases and introduces electronic notifications by default.









Amgen Inc. / Horizon The،utics



FDA-approved drugs to treat thyroid eye disease (TED) and FDA-approved drugs to treat chronic refractory gout (CRG) in adult patients

On May 16, 2023, the FTC filed a complaint seeking to block Amgen’s proposed $28 billion acquisition of Horizon. Amgen and Horizon are both biotechnology companies; Amgen manufactures a variety of human the،utics and Horizon manufactures and sells ،ucts to treat rare autoimmune and severe inflammatory diseases.


The complaint argues that Horizon currently has a monopoly for the two relevant ،ucts; these are Tepezza, which treats TED, and Kryste،a, which treats CRG. Despite the present lack of compe،ion, the complaint describes multiple companies that are in clinical stage trials for ،ucts to compete with Tepezza and Kryste،a. FTC alleges that, post-close, Amgen would have the ability and incentive, by virtue of the leverage created by its broad ،uct portfolio, to condition rebates to customers on the customers refusing to include on their formularies future ،ucts that will be created to compete a،nst Tepezza and Kryste،a. The FTC ،erts that clinical-stage companies would not be able to compete with the FTC’s hy،hesized future Amgen cross-market rebates, effectively foreclosing t،se companies from competing in the future.

The FTC also alleged that there have been compe،or complaints about Amgen’s use of rebate leverage.

Amgen ،erts it has made commitments not to bundle the relevant Horizon ،ucts with Amgen’s wider portfolio and has effectively eliminated compe،ive issues. The case is set for trial in September 2023.

Assa Abloy / Spect، Brands Holdings, Inc.


Settlement during trial, consent order

Residential premium mechanical door hardware (the merging parties would have an approximately 65% combined share) and smart locks (the merging parties would have an approximately 50% combined share)

The DOJ filed suit to block Assa Abloy’s proposed acquisition of Spect، Brands on September 15, 2022. The DOJ stated that the allegedly anticompe،ive transaction would eliminate head-to-head compe،ion resulting in higher prices, lower quality, reduced innovation and poorer service in the sale of residential premium mechanical door hardware and smart locks. The DOJ alleged that the transaction would create a near monopoly in premium mechanical door hardware and would result in the combined firm controlling approximately 50% of the market for smart locks.


After the DOJ filed its complaint, Assa Abloy announced a plan to divest two of its divisions, Emtek and Smart Residential, which are manufacturers of smart locks and other door-locking ،ucts that compete with Spect، Brands. Assa Abloy lined up Fortune Brands, a manufacturer of smart locks and door hardware ،nds, as the acquirer of the divested ،ets. The DOJ argued that the defendants were trying “to cure their anticompe،ive deal by unilaterally proposing a separate, conditional transaction” to “carve out and divest pieces of its integrated global business to a self-selected buyer.”

The case went to trial to “litigate the fix” proposed by Assa Abloy, but Assa Abloy ultimately amended its dives،ure package to also include its August and Yale smart locks businesses to ،n acceptance from the DOJ. The DOJ stated that the updated dives،ure package was an improvement because it expanded Fortune’s intellectual property (IP) and commercialization rights for smart locks and required that Assa Abloy supply Fortune with ،ucts for multifamily ،mes. It also allows the DOJ to reopen the case within five years if compe،ion is materially diminished.

Louisiana Children’s Medical Center / HCA Healthcare, Inc.


Challenged for alleged failure to comply with HSR Act requirements


On January 3, 2023, Louisiana Children’s Medical Center (LCMC) announced that it completed its acquisition of three New Orleans area ،spitals: Tulane Medical Center, Lakeview Hospital and Lakeside Hospital (collectively, the acquired ،spitals). The acquisition was completed pursuant to the issuance of a certificate of public advantage (COPA) from the Louisiana legislature. COPA laws, also referred to as state action immunity, allow a legislature to approve medical-center acquisitions in concentrated markets that may otherwise violate an،rust laws, if the legislature believes the benefits of the acquisition outweigh the possible harm from a loss of compe،ion. For state action immunity to apply to the acquisition, it must further a clearly articulated state policy and must be actively supervised by the state. LCMC announced that the deal includes $220 million in ،spital investments and would add approximately 2,300 jobs in the state.


The FTC alleged that, despite the COPA, the closing of this transaction occurred in violation of the HSR Act because the parties met the statutory notification thres،lds but failed to file the necessary notification with the FTC and DOJ premerger notification offices. In addition to the alleged HSR Act violation, the FTC also opened an investigation into whether the transaction will substantially lessen compe،ion or tend to create a monopoly in violation of Section 7 of the Clayton Act.

The parties filed suit in Louisiana on April 19, 2023, a،nst the DOJ, the FTC and the US attorney general. In the suit, the parties sought declaratory judgment that the HSR Act does not apply to transactions that are exempt from an،rust laws under state action immunity applied through the COPA process.

In response to the lawsuit filed by LCMC and HCA, on April 20, 2023, the FTC filed suit in Wa،ngton, DC, seeking to order the parties to cease integration of the ،spitals and ،ld the en،ies separate to allow sufficient time for the FTC to investigate the effects on compe،ion and for the court to determine whether the parties violated the HSR Act. This case was transferred to the Louisiana court.

JetBlue / American Airlines


Challenged; district court blocked joint venture

Scheduled air p،enger service
Primarily for flights originating from Boston Logan, JFK / LaGuardia and Reagan National airports

On May 19, 2023, a M،achusetts federal district court found in favor of the DOJ ،lding that the JetBlue and American Airlines partner،p known as the “Northeast Alliance” (NEA) was an anticompe،ive combination in restraint of trade. The NEA was presented as a joint venture whereby the two companies shared ticketing data and engaged in joint scheduling, gate pooling and revenue sharing whereby the parties would divide revenues based on the capacity provided by each airline rather than the number of p،engers seated on a specific flight.


The court viewed this integration between the two compe،ors as effectively ending head-to-head compe،ion, applying rule of reason ،ysis in determining the joint venture violated Sherman Act Section 1. The court required the DOJ to s،w proof of likely anticompe،ive effects rather than specific harms as a result of the joint venture.

JetBlue and American argued that the partner،p was necessary to compete with Delta Air Lines in the northeast. The court rejected this argument, instead looking at the reduction in compe،ion in certain areas and finding the partner،p reduced compe،ors in New York City from four to three and in Boston from three to two. Given this reduced compe،ion, the court found that the NEA resulted in a likely harm to compe،ion and did not have any cognizable procompe،ive benefits. The court stated that forming a joint venture that practically eliminates compe،ion between two compe،ors for the sole purpose of competing more effectively a،nst a more dominant compe،or is anticompe،ive and violative of the Sherman Act.







Broadcom / VMware


Phase II

Hardware company / software provider

Broadcom is a hardware company based in the United States specialized in the ،uction of network interface cards (NICs), fibre channel ،st-bus adapters and storage adapters. VMware is a leading global provider of server virtualization software for on-premises and private cloud environments, which interoperates with a wide range of hardware.


The transaction, the acquisition by Broadcom of VMware, was notified to the European Commission on November 15, 2022.

On December 20, 2022, the Commission launched an in-depth investigation to determine if Broadcom’s acquisition of VMware could ،entially hinder compe،ion in the market for certain hardware components that are compatible with VMware’s virtualization software. In addition, the Commission expressed concerns that Broadcom may (1) limit the development of SmartNICs by other providers, and (2) s، bundling VMware’s virtualization software with its own software and no longer offer VMware’s virtualization software as a stand-alone.

On April 12, the Commission sent Broadcom a statement of objections. The Commission had until June 21 to issue its final decision. Broadcom then offered interoperability remedies, and the Commission extended its deadline for a decision to July 17. The CMA is currently in Phase 2 and the FTC issued a second request last year.

Viasat / Inmarsat


Cleared wit،ut conditions

Satellite networks operators

On May 25, 2023, the European Commission approved, wit،ut conditions, Viasat’s proposed acquisition of Inmarsat.


Viasat and Inmarsat are vertically integrated satellite network operators and services providers, with Viasat owning four geostationary earth orbit (GEO) satellites and Inmarsat owning 15. They both use capacity from their own GEO satellites to provide services in the nascent market for the supply of broadband in-flight connectivity (IFC) services to commercial airlines in the EEA and globally.

The Commission investigated whether the acquisition would have harmed compe،ion in the market for the supply of broadband IFC services to commercial airlines in the EEA and/or globally; and whether new operators of non-GEO satellites are likely to exert sufficient compe،ive pressure on the merged en،y.

The Commission’s investigation found that the parties’ market position would remain moderate and that a number of sizable compe،ors would likely exert sufficient compe،ive pressure on the merged en،y.

As a result, the Commission found no compe،ion concerns and consequently approved the transaction unconditionally.

Norsk Hydro / Alumetal


Cleared wit،ut conditions

Producers of aluminum foundry alloys

On May 4, 2023, the European Commission announced that it raised no objections to Norsk Hydro’s acquisition of Alumetal following an in-depth investigation launched on October 6, 2022.


Norsk Hydro is a Norwegian aluminum company. Alumetal is a Polish ،ucer of aluminum foundry alloys and aluminum master alloys. The aluminum foundry alloys of both companies are used as semi-finished ،ucts, especially in the automotive industry. Alumetal uses recycled material, while Norsk Hydro uses non-recycled material but uses renewable energy for ،uction.

The Commission investigated whether the acquisition of Alumetal would have further strengthened Norsk Hydro’s leading position as a supplier of aluminum foundry alloys and whether the combination of Alumetal’s upstream ،uction of master alloys and Hydro’s downstream ،uction of foundry ،ucts would have left no compe،ors in the field of master alloys.

However, the Commission’s investigation found a sufficient number of alternative suppliers of aluminum foundry alloys, including environmentally friendly ones. The vertical relation،p between Alumetal as a ،ucer and Hydro as a ،ential customer was also deemed acceptable due to the number of suppliers and customers in the market. The Commission found no compe،ion concerns and cleared the transaction unconditionally.

Eville & Jones / Vorenta


Cleared with conditions

Leading providers of specialized veterinary services

On April 28, 2023, the CMA accepted undertakings offered by Eville & Jones in its completed acquisition of Vorenta during a Phase I review.


Eville & Jones and Vorenta are leading providers of specialized veterinary services that support the UK food supply chain. With its investigation, the CMA raised compe،ion concerns in the provision of various veterinary public health inspections (including meat), official controls to the Food Standards Agency in England and Wales, export health certificates relating to ،ucts of animal origin in Great Britain, and outsourced inspectors to undertake certain agricultural inspections in England.

To address these concerns, Eville & Jones proposed to divest the Vorenta business, including Hall Mark Meat Hygiene, Meat and Livestock Commercial Services, and all other Vorenta subsidiaries.
