Summary of Update:
The CNMC has intensified its merger control enforcement, marked by a continued trend for conditional Phase II authorisations, procedural fines and even one prohibition decision. For example, just after the COVID lockdown, the CNMC raided a company in the insurance sector based on gun jumping allegations. Furthermore, the Government's intervention in BBVA/Sabadell has reopened the debate about the limits of the Council of Ministers' powers in merger control.
Merger prohibition decision
On 6 October 2025, the CNMC blocked the acquisition of the Institut de Radiofarmacia Aplicada de Barcelona ("IRAB") by Curium Pharma Holding Spain on the basis of alleged significant risks to competition in the market for PET radiopharmaceuticals used in cancer diagnostics. The CNMC considered that the transaction would result in high combined market shares, reduce potential competition, and strengthen Curium's position in geographic areas where it previously lacked presence.
The blocking of mergers under the Spanish merger control regime is extremely rare, as the system empowers the CNMC to unilaterally impose conditions when the commitments offered by the parties are deemed insufficient to resolve identified competition concerns. This decision represents the CNMC's first prohibition of a merger since its establishment in 2013 and demonstrates the CNMC's readiness to block mergers where competition concerns cannot be remedied through conditions. (Under the former competition regime, there had been two prohibition decisions (Telefónica/Iberbanda; and Gas Aragón/Endesa/Gas Natural SDG/Gas Andalucía/Megasa).)
Ongoing trend of conditional Phase II clearances
In 2025, the CNMC conditionally cleared two Phase II transactions (BBVA/Sabadell and Esseco/Ercros). This continues a trend seen in previous years: 2024 saw one conditional clearance and one withdrawal at Phase II, while 2023 saw two deals conditionally cleared and two more withdrawn at Phase II. The CNMC's 2024 official report explained that this increase "follow[s]…a trend of growing complexity in transactions. This is reflected in a rise in the number of concentrations cleared with commitments and the need for a more in-depth assessment of the implications of certain transactions during the second phase".
Heightened procedural scrutiny
The CNMC has ramped up its enforcement of procedural obligations, particularly regarding the accuracy and completeness of information submitted during notifications. In Rheinmetall/Expal, Rheinmetall was fined €13 million for failing to disclose relevant market overlaps and obstructing the authority's investigation during the review process. The omission involved sensitive defence-related markets such as nitrocellulose and wet pulp.
The CNMC has also increased its monitoring of gun jumping. Recent fines include:
· €83,000 against PME and €23,700 against its subsidiary HM Salamanca for acquiring control of Hospital General de la Santísima Trinidad without prior notification.
· €683,322 against KKR Genesis for failing to notify its acquisition of GeneraLife, which itself had previously breached notification rules in acquiring Ginemed.
While these fines (the highest being €1.5 million) remain modest compared to those issued by the EC and other national authorities such as France, these cases underscore the CNMC's commitment to upholding the standstill obligation and its willingness to impose substantial penalties for procedural breaches.
Political oversight and public interest intervention in strategic mergers
The BBVA/Sabadell merger has brought to light current debates over the Spanish government's political oversight in merger control. Although the CNMC conditionally cleared the deal at Phase II, the Council of Ministers subsequently intervened by imposing additional conditions, including a three-year obligation (extendable up to five years) for BBVA and Sabadell to remain as separate legal entities.
While Spanish competition law allows the government to intervene in merger clearance proceedings, said intervention can only be justified for legitimate interests other than competition law and is subject to the principles of necessity and proportionality. On 15 July 2025, BBVA filed an appeal before the Supreme Court against the Government's decision, arguing that the conditions constitute a disproportionate and discriminatory restriction contrary to Spanish and EU law, and that the requirement for both entities remain separate for up to five years constitutes a "de facto prohibition" of the merger and exceeds the limits of the Government's legal power.
The EC has also initiated infringement proceedings against the Spanish state, arguing that the discretionary powers granted to the Spanish Council of Ministers to intervene in mergers that "impinge on the exclusive competences of the European Central Bank and national supervisors under the EU banking regulations" and "constitute unjustified restrictions to the freedom of establishment and of capital movements". The EC considers that consolidations in the banking sector benefit the EU economy as a whole; are essential for the achievement of the Banking Union; ensure that capital is allocated efficiently across the EU; and that citizens and businesses have access to financial products at competitive prices.
Beyond this debate, this case also illustrates a broader trend in Spain where public interest considerations (e.g., financial inclusion, regional development and consumer protection) are increasingly influencing assessments of mergers. A notable example is the clearance of CaixaBank's acquisition of Bankia subject to commitments aimed at ensuring financial inclusion.
Sector Relevance: Life sciences, banking, defence, infrastructure, and any sector involving high market concentration or strategic relevance.
Why it matters / Key takeaways:
- The CNMC shows it is ready to prohibit mergers where competition concerns cannot be resolved through remedies.
- The ongoing trend of conditional Phase II approvals highlights the sustained complexity of merger reviews.
- Procedural compliance is under sharper scrutiny, with fines for gun jumping and misleading information setting new enforcement benchmarks.
- Political and public interest considerations are influencing merger outcomes, as seen in the BBVA/Sabadell case.
- Companies should prepare for more rigorous and multi-layered merger review processes and ensure strict adherence to notification and standstill obligations.
