Amprius Technologies' Q4 earnings report showed the company met its EPS estimates and reported a notable increase in revenue compared to the previous year. Historically, the company's stock price increased by 18.0% the day after beating EPS estimates in Q3 2023. However, this quarter's performance, while solid, merely met expectations, which might not trigger a significant stock price movement. The revenue growth is positive, but the exact impact on the stock price in the short term is uncertain, hence a neutral score.
