Key Dates

Recommendation

While the Q1 2026 results show significant year-over-year revenue growth and improved gross margins, driven by increasing 5G chipset shipments, the company continues to incur substantial net losses and carries a significant accumulated deficit. The positive operational momentum is encouraging, but the path to profitability remains uncertain, and the company's financial structure warrants caution. Therefore, a 'hold' recommendation is appropriate, pending further evidence of sustained growth and a clearer path to profitability.
