Liquidity and Going Concern

The Company has incurred significant operating losses and cash outflows from operating activities since its inception. As of December 31, 2025 and 2024, the Company had an accumulated deficit of $64,348,118 and $28,903,903, respectively.

These measures could cause significant delays or entirely prevent the Company's continued efforts to commercialize its current or future products, which are critical to the realization of its business plan and the future operations of the Company.
