What to watch

And the other side of it.

The offsets in the same document — the things a summary that only listed the good news would have left out.

Rising Operational Costs
R&D costs spiked by approximately $1.1 million compared to the same period last year, reflecting ongoing development challenges.
Cash Flow Concerns
Net cash used in operating activities reached $6.2 million, a concerning trend as the company continues to burn cash.
Dependence on External Funding
