What drove the net profit growth in Q4 2024?

The net profit growth in Q4 2024 was primarily driven by the following factors:

1. **Adjusted EBITDA Performance**: United States Steel Corporation (X) reported an adjusted EBITDA of $190 million for the fourth quarter of 2024. This indicates a strong operational performance, which is a key indicator of the company's profitability.
2. **Cost Control and Operational Efficiency**: The company's focus on cost control and operational efficiency in the North American Flat-Rolled segment contributed to better-than-expected cost performance. This segment generated a 10% EBITDA margin, benefiting from a resilient commercial strategy and a diverse product mix.
3. **Increased Volumes in the Mini Mill Segment**: There was an improvement in volumes in the Mini Mill segment, which partially offset the impact of planned maintenance activity at Big River. This suggests that despite the challenges, certain segments of the company are performing well and contributing to the overall profitability.
4. **Strategic Investments**: The company's investment in growth capital projects, such as the completion of over $4 billion in growth capital investments, including the first coil at Big River 2, is expected to bolster future earnings and cash flow. While these investments may have short-term impacts on profitability, they are likely to contribute to long-term growth.

In conclusion, the net profit growth in Q4 2024 was driven by a combination of strong operational performance, cost control, strategic investments, and improvements in certain segments of the business.
