Vodafone Group PLC shares fell as much as 1.5% on Wednesday. The stock price reached 129.3 pence during the session.

The company faces a potential earnings loss of up to €1.1 billion. This exposure relates to the sale of Patrick Drahi’s 50% stake in OXG Glasfaser, Vodafone’s German broadband fiber joint venture.

Société Générale acquired the stake but reportedly declined to assume deferred payment commitments. This refusal raised investor concerns regarding Vodafone’s financial exposure and the venture's future profitability.

Analysts categorized the development as company-specific, noting that telecommunications peers reported no similar negative catalysts. The situation adds uncertainty to the German fiber rollout, which remains a key strategic partnership for Vodafone.
