Nokia has lowered its full-year adjusted operating profit guidance for 2025 to a range of €1.6 billion to €2.1 billion, down from the previous estimate of €1.9 billion to €2.4 billion. The Finnish telecommunications equipment maker attributed the revision primarily to currency headwinds, notably a weaker US dollar which is estimated to have a negative impact of approximately €230 million, and increased tariffs, expected to reduce profits by up to €80 million. For the second quarter of 2025, Nokia anticipates revenue around €4.55 billion and an adjusted operating loss of €300 million, missing analyst estimates of €4.80 billion in sales and €407.1 million in operating profit. The company cited the ongoing effects of tariffs implemented under former US President Donald Trump's administration and currency fluctuations as key challenges. Following the guidance cut, Nokia's shares declined by over 8% in pre-market trading. This development comes amid broader market volatility and pressure on technology sector earnings.
