Why did CHTR's net profit surge in Q4 2024?

Charter Communications' net profit surged in Q4 2024 due to several key factors:

1. **Revenue Growth**: The company's revenue increased by 1.6% year-over-year, reaching $13.9 billion. This growth was driven by strong performance in both mobile services and advertising sales. Residential mobile service revenue surged by 37.4%, and advertising sales revenue jumped by 26.4%. The addition of over 529,000 mobile lines in the quarter contributed significantly to this growth.
2. **Cost Control**: Charter's adjusted EBITDA grew by 3.4% year-over-year to $5.8 billion. This increase was supported by revenue growth and controlled operating expenses, which helped in improving the net profit margin.
3. **Strategic Initiatives**: Charter's strategic initiatives, such as the launch of the new brand platform, Life Unlimited, and the focus on lower promotional and bundled pricing, are likely to have boosted its market position and driven growth.

In summary, Charter's net profit surge in Q4 2024 can be attributed to a combination of revenue growth, cost control, and strategic initiatives.
