Why did POET's operating expenses surge in Q4 2024?

POET Technologies did not report any operating expenses for Q4 2024. However, it is important to note that the company did report a net loss of $30.2 million for the quarter, which was primarily due to non-cash adjustments and increased research and development expenses. While the company did not provide a detailed breakdown of its expenses, it is clear that POET's focus on strategic advancements and financial strengthening may have led to increased expenses related to acquisitions, supply chain optimization, and research and development. These expenses are likely to have been necessary investments for the company's long-term growth and competitiveness in the AI and data center markets.
