STRATA Skin Sciences shares fall 47.5% after-hours after Nasdaq delisting due to failing stockholders' equity requirements.

think> Okay, let's tackle this query. The user wants me to act as a financial analyst explaining the stock price movement of STRATA Skin Sciences. The stock dropped 47.5% in after-hours trading. The news events provided all relate to the company's delisting from Nasdaq due to failing equity requirements. First, I need to confirm the direction and trading session. The stock went down by 47.5% after hours. The news events all mention a 60.8% plunge in premarket trading, but the user's input says after-hours. Wait, there might be a discrepancy here. The news events mention premarket, but the user's input says after-hour. I need to check if they're the same or different. The user's input says the stock's performance is after-hour down 47.5%, but the news events talk about premarket. Maybe the delisting announcement happened during the after-hours, leading to a premarket drop? Or perhaps the user's input is incorrect. Hmm. Wait, the user's input is in Chinese, so "盘后 after-hour" translates to after-hours trading. The news events mention premarket trading. So there's a conflict here. But the user's input says the stock's movement is after-hours down 47.5%, but the news events talk about premarket. This might be a mistake in the input or a misunderstanding. However, the key point is that the delisting caused the stock to drop. The percentage in the news is 60.8% in premarket, but the user's input says 47.5% in after-hours. Maybe the after-hours is part of the premarket? Or maybe the user mixed up the terms. But according to the news, the stock plummeted 60.8% in premarket trading after the delisting announcement. The user's input says after-hour down 47.5%. That's conflicting. But perhaps the user is using "after-hour" to refer to the premarket? Not sure. But the news events clearly state the premarket drop. The user's input might have a typo. However, I need to follow the user's input as given. So the user says the stock's performance is after-hour down 47.5%, but the news events mention premarket. So maybe the user is referring to the after-hours session, but the news events are about premarket. That's conflicting. But since the user is the one providing the data, I have to work with that. Wait, maybe the user is Chinese and "盘后 after-hour" refers to the after-hours trading, but in the news, it's premarket. So the delisting announcement was made after the market closed, leading to a premarket drop. So the user is referring to the after-hours movement, but the news is about premarket. But the user's input is about after-hour. However, the news events are the cause. So perhaps the user made a mistake in the trading period, but I have to proceed with the given data. Next, evaluate each news event. All six news events are about STRATA failing to meet Nasdaq's equity requirements, leading to delisting. All of them are relevant and bearish. The stock's movement is down, and the news events are bearish, so they align. The key point is the delisting announcement causing the stock to drop. The percentage in the news is 60.8% in premarket, but the user's input is 47.5% in after-hours. But the user's input might be a typo. However, the user's instruction says to use the provided data. So I should use the 47.5% after-hours drop as per the user's input, even if the news mentions premarket. The explanation should link the after-hours drop to the delisting news. Now, the concise explanation needs to mention the stock's movement, the trading session, and the key news. The delisting due to failing equity requirements is the cause. The stock is going dark, which reduces liquidity and is negative for shareholders. I need to round -47.5% to two decimal places, which is -47.50%. But the user's example shows rounding to two decimal places and removing trailing zeros. Wait, the example had 4.230769% rounded to 4.23%. So 47.5% should be 47.50% but since it's already one decimal, maybe just 47.5%. Wait, the instruction says to round to two decimal places and remove trailing zeros. So 47.5% is 47.50%, but if there are trailing zeros after the decimal, they are removed. So 47.5% becomes 47.5% (no decimal places). Wait, the example had 4.
