Citigroup has downgraded International Paper Company (NYSE:IP) from 'Buy' to 'Neutral' and reduced its price target from $53 to $46 per share, reflecting growing concerns about the company's financial stability. Although International Paper is experiencing a 19.7% improvement in its current year consensus earnings estimate and strong demand for its products, it faces challenges with significant total debt of approximately $11 billion and a low growth score of 'F'. This downgrade raises questions about the company's ability to sustain investor confidence moving forward.
