On 21 October 2026 the Spanish Competition Authority (CNMC) opened a formal investigation into Exolum’s pricing practices in the transport and storage of liquid hydrocarbons, biofuels and chemicals. The action introduces a stricter test for dominant firms that set prices below inflation, aligning Spanish enforcement more closely with EU competition doctrine. Exolum and other market‑leaders in energy logistics now face the prospect of sanctions unless they can substantiate their pricing methodology. The probe clarifies that modest price rises do not automatically shield a dominant player from abuse allegations.

Full News Breakdown

The CNMC acted after receiving complaints that Exolum was using its market power to impose unjustified prices on downstream users. Exolum argues that its long‑standing policy of keeping annual price increases below the consumer‑price index is transparent and cost‑based, while complainants contend that the policy masks exploitative pricing. The authority decided to launch a full‑scale inquiry, demanding detailed cost data and pricing models from the company.

• Case Name: Exolum v. CNMC

• Court: Spanish Competition Authority (CNMC)

• Panel: Not applicable (administrative authority)

• Date: 21 October 2026

• Citation: S/0005/26

• EU Instruments / UK Legislation Cited: Treaty on the Functioning of the European Union (TFEU) Art 102, Spanish Law 15/2007 on the Defence of Competition Art 13

• Key Provisions: TFEU Art 102 (abuse of dominant position), Spanish Law 15/2007 Art 13 (abuse of dominance)

• Primary Legal Issue: Whether a pricing policy that yields increases below inflation can constitute an abuse of dominance under Art 102 TFEU and Spanish competition law

• Applicant/Plaintiff Arguments: Prices are unjustified, exploitative, and restrict market entry; the policy lacks a cost‑plus justification

• Respondent/Defendant Arguments: Pricing is transparent, based on long‑term contracts, and consistently below inflation, reflecting efficient cost recovery

• Court's Reasoning: The authority emphasised that abuse assessment must consider the relationship between market power and pricing effects, not merely the magnitude of price changes; reference was made to EU case law on exploitative pricing

• Holding: Formal investigation opened; no final determination on abuse at this stage

• Operative Order: CNMC to collect all pricing data, cost structures, and contractual terms from Exolum within 30 days; company may be subject to fines up to 10 % of worldwide turnover

• Practical Outcome: Exolum must prepare a comprehensive pricing dossier and may face interim measures if cooperation is deemed insufficient

How Does This Affect You?

Before the CNMC action, the boundary between acceptable low‑inflation pricing and exploitative conduct was uncertain for dominant energy‑logistics firms. The authority now clarifies that modest price increases do not per se exempt a dominant player from an abuse finding. Practically, companies must be ready to justify their pricing methodology with detailed cost data, and advisers should anticipate heightened scrutiny of “transparent” pricing policies.

For Lawyers & Advocates

• Review and update clients’ cost‑allocation models for hydrocarbon transport to ensure they can be disclosed in a CNMC information request under Art 102 and Spanish Law 15/2007.

• Amend commercial contracts to embed explicit cost‑plus or indexation clauses, providing a defensible benchmark if pricing is later challenged as exploitative.

• Prepare a defensive filing that cites EU precedent such as United Brands and AKZO, and submit it within the CNMC’s 30‑day information deadline to shape the factual record.

• Advise energy‑logistics clients that the CNMC may now treat “low‑inflation” price policies as a red flag, increasing exposure to fines of up to 10 % of global turnover.

• Re‑evaluate risk assessments for all dominant firms in similar markets, noting that the probe expands the definition of “unfair pricing” beyond excessive price levels.

For Law Students

The case illustrates that courts assess abuse of dominance by examining the economic effect of a pricing policy, not merely the size of price changes.
The core doctrinal distinction is between “excessive pricing” and “unfair pricing” under Art 102 TFEU.
The decision is particularly relevant for the study of:

• EU competition law doctrine

• Abuse of dominance analysis

• Energy market regulation

• Pricing strategy in antitrust contexts

• Comparative competition enforcement in the EU and national systems
  United Brands (C‑27/76) and AKZO Chemie (C‑62/96) are comparable cases; contrasting them with the Exolum probe shows how the EU courts have progressively broadened the scope of exploitative pricing beyond simple price‑level tests.

For Businesses

• Energy‑logistics operators must audit their pricing policies and be prepared to produce cost‑plus calculations to satisfy CNMC inquiries, or risk substantial fines.

• CFOs should verify that internal price‑adjustment mechanisms align with documented cost structures; failure to do so may trigger regulatory scrutiny and affect credit ratings.

• Companies should amend compliance registers to record CNMC reporting obligations for dominant positions, ensuring that any future price changes are logged and justified.

• Boards need to consider appointing a dedicated antitrust compliance officer to oversee pricing decisions and coordinate responses to competition‑authority requests.

Key Takeaways

• Low‑inflation price increases can still be deemed abusive under Art 102 TFEU and Spanish competition law, closing a previous evidential gap.

• Lawyers must now secure and preserve detailed cost‑plus pricing documentation for dominant firms to withstand CNMC investigations.

• The CNMC can launch investigations based solely on a pricing policy, without needing proof of price hikes above inflation.

• Watch for the European Commission’s revision of the 2024 Guidelines on abuse of dominance, slated for publication in the second quarter of 2027.

• General Counsels should commission a pricing audit before 31 December 2026 to mitigate exposure to the newly clarified abuse test.
