NATURGY ENERGY GROUP SA
NATURGY ENERGY GROUP SA is a Spanish public limited company (sociedad anónima) registered in Spain under CIF A08015497 and recorded as active by the Colegio de Registradores / Registro Mercantil Central. The company traces its corporate lineage to the Sociedad Catalana para el Alumbrado por Gas, formed in Barcelona in January 1843 to supply piped gas street lighting to the city; through successive mergers and renamings — including long periods as Gas Natural SDG and, from 2009, Gas Natural Fenosa, before adopting the Naturgy name in 2018 — the same corporate line has continued in business for over 180 years. The registry incorporation date on file, 1 January 1843, reflects a verified founding year but an unverifiable exact day: the company’s own Fundación Naturgy historical archive and its official corporate history both confirm constitution in “January 1843” without stating a specific day, so the “01-01” on file appears to be a default day/month placeholder rather than a recorded historical date, while the year 1843 itself is genuinely accurate.
NATURGY ENERGY GROUP SA is a multi-utility engaged in the regulated distribution and open-market supply of natural gas and electricity in Spain, together with electricity and renewable power generation, liquefied natural gas (LNG) supply, and international energy operations in Latin America, including Argentina, Brazil, Mexico, Panama, Chile and the Dominican Republic. Its Spanish gas-distribution activity is carried out mainly through its subsidiary Nedgia, while international power generation is grouped mainly under Global Power Generation. NATURGY ENERGY GROUP SA is listed on the Spanish stock exchanges operated by Bolsas y Mercados Españoles (BME) under the ticker NTGY and is a constituent of the IBEX 35 index.
Naturgy’s disclosed shareholder base changed materially during 2026. CriteriaCaixa, the investment arm associated with Fundación La Caixa, acquired a further 2.5% of the company’s capital for a reported €611 million in early 2026, reported to take its stake to around 28.5% and reinforce its position as the largest shareholder. Separately, on 27 May 2026 the CVC-linked Rioja Acquisition / Corporación Alba vehicle completed a full exit, placing its remaining 13.8% stake — an 11.08% accelerated bookbuild plus liquidation of derivative positions equivalent to 2.72% — for a reported €3.82 billion, ending an investment held since 2018. These transactions, and the company’s fuller shareholder structure, are covered with sourcing in the shareholders block of this profile.

Shareholders
Shareholders of NATURGY ENERGY GROUP SA
Zavia’s Spanish registry source (Colegio de Registradores / Registro Mercantil Central) does not display a shareholder filing for NATURGY ENERGY GROUP SA; this is expected for a listed company, since Naturgy discloses its share ownership through significant-shareholding notifications to Spain’s securities regulator, the CNMV, rather than through the standard company-registry shareholder filing used for non-listed entities. According to Naturgy’s own investor-relations disclosures, the company had around 65,000 shareholders as of May 2026. Reputable Spanish financial-press reporting, referencing CNMV significant-shareholding notifications, identifies CriteriaCaixa (the investment arm associated with Fundación La Caixa) as the largest disclosed shareholder, reported at approximately 28.5% of capital following an additional 2.5% purchase for around €611 million completed in early 2026. The same reporting describes a full exit, completed on 27 May 2026, by the CVC-linked Rioja Acquisition / Corporación Alba vehicle, which placed its remaining 13.8% stake (an 11.08% accelerated bookbuild plus derivative positions equivalent to 2.72%) for a reported €3.82 billion, ending an investment held since 2018. Some financial-data sources also report a stake of around 12.62% associated with BlackRock, which press coverage links to Global Infrastructure Partners’ (GIP) historical position in the former Rioja consortium following BlackRock’s acquisition of GIP in October 2024; this attribution was not independently confirmed against a primary CNMV filing in this research session and is presented as reported, not verified.
Data availability
Shareholder disclosure for this company is Major shareholders only: as a listed company, only stakes crossing regulatory notification thresholds are publicly disclosed, and the figures above come from reputable financial-press reporting on CNMV notifications rather than a primary CNMV filing accessed directly in this research session (the CNMV’s online significant-shareholdings query tool returned no data through the automated retrieval method used here). No ultimate-beneficial-ownership section is included because no source reviewed supplied a complete, dated ownership chain from a disclosed corporate shareholder to a named natural person that could be verified or calculated.

Directors and officers of NATURGY ENERGY GROUP SA
Zavia’s Spanish registry source records five active officer entries for NATURGY ENERGY GROUP SA out of a reported 25 total registry officer records: Francisco Massanet (Consejero Delegado), Helena Herrero Starkie (Consejero Independiente), Ramon Adell Ramon (Consejero Dominical), Steven Fernandez Fernandez (Head Of Financial Markets Department) and Maria Isabel Gonzalez Alfaro (Head Of Compliance Unit), all listed with ACTIVE status, Spain as address country, and no appointment or resignation dates recorded. Naturgy’s own corporate-governance disclosures, reviewed separately, show the Board of Directors was set at sixteen members at the Annual General Meeting held on 25 March 2025, with Francisco Reynés Massanet holding the combined role of Chairman and Chief Executive Officer (Presidente y Consejero Delegado) since February 2018. The “Francisco Massanet / Consejero Delegado” entry in the registry source is consistent with this same person, though the registry record omits his paternal surname “Reynés” and his Chairman title — a naming discrepancy noted here rather than corrected, since the underlying registry record itself was not amended.
Data availability
Officer information is Partial: the registry source lists only 5 of a reported 25 officer records, without appointment dates, occupation or nationality fields, and does not reconstruct the full board; official company sources confirm current board size and the identity of the Chairman & CEO but were not used in this session to compile the complete sixteen-member board roster. Nationality and country of residence are Not disclosed in every source reviewed and have not been inferred from any officer’s name, address or reported role.
Recent officer changes
No verified, dated appointment or resignation changes could be confirmed from the sources reviewed in this session beyond the general 25 March 2025 Annual General Meeting confirmation of board size; this section is otherwise limited for lack of further reliable, dated change records.

Recent structural changes
No verified acquisitions, disposals or reorganisations affecting Naturgy’s own subsidiary structure were identified in the sources reviewed for this profile. The material ownership changes at NATURGY ENERGY GROUP SA shareholder level during 2026 — CriteriaCaixa’s additional 2.5% purchase and the CVC-linked Rioja Acquisition / Corporación Alba exit — are shareholding changes in Naturgy itself rather than changes to Naturgy’s own subsidiary structure, and are covered in the shareholders block of this profile.
Data availability
Corporate-linkage information for this company is Partial: registry-derived data identifies a large number of subsidiaries by name, country and registration number but does not disclose ownership percentages or status for any of them, and this profile has not independently verified each entity against its own official filing given the size of the structure.

The registry date on file, 1843-01-01, therefore appears to combine a verified founding year with a default 1 January placeholder for the day and month, a pattern seen elsewhere in this database when only a year is known.
