These are the key contradictions discussed in Tower Semiconductor's latest 2024Q4 earnings call, specifically including: RF mobile market expectations, silicon photonics revenue growth, and mobile market expectations:



Revenue Growth and Strategic Developments:
- Tower Semiconductor reported an annual revenue of $1.44 billion for fiscal year 2024, with a 18% increase from Q1 to Q4.
- The growth was driven by strong performance in RF infrastructure and strategic developments in areas like silicon photonics and silicon germanium technologies.

RF Infrastructure Expansion:
