Shares of Elisa, Finland's largest mobile operator, plunged over 6% following disappointing fourth-quarter earnings and a conservative profit forecast for 2026. Revenue reached €588 million, slightly below expectations. Declining mobile service revenue growth and a loss of postpaid subscribers contributed to the negative sentiment. One-off charges also weighed on the results.

Comparable EBITDA rose modestly, missing analyst estimates. The company attributed the performance to intense 4G competition. Investors are also concerned about slowing growth in mobile service revenue. For 2026, Elisa anticipates revenue at a similar level to 2025 and projects comparable EBITDA within a specific range.

Elisa's cautious outlook for 2026, despite a transformation program aimed at cost savings, disappointed investors. The board declared a dividend of €2.40 per share, which was lower than anticipated. Facing headwinds, the company is focusing on cost-cutting measures to improve profitability.

Looking ahead, market participants will closely monitor Elisa's progress in implementing its transformation program and its ability to navigate the competitive telecom landscape. The company's performance in the face of ongoing competition will be key to investor confidence. The focus will be on the 2026 profit guidance.
