Management Qualitative Comments

“Amidst a backdrop of turbulent geopolitical and global economic conditions, AXT posted a solid quarter,” said Morris Young, chief executive officer. "Revenue came in just ahead of our expectations and our indium phosphide sales achieved an all-time high. In addition, we reduced our inventory, increased our cash and improved our gross margin.  We are continuing to execute on the relocation of our facility and believe that we are laying a solid foundation for the significant technology trends that are likely to drive growth in our business over time."
