The announcement of Airgain's at-the-market issuance sales agreement to sell shares up to $5 million could lead to dilution of existing shares, potentially causing a short-term negative impact on the stock price. The relevance is high as the news directly involves Airgain. The importance is significant due to the potential dilution effect, but not critical as the amount is relatively small compared to the company's market cap. The confidence level is high due to the direct correlation between share dilution and stock price impact.
