iBio shares surge 20.19% intraday following credit agreement amendment with Woodforest.

think> Okay, let's tackle this query step by step. The user provided a stock performance for iBio (IBIO) which went up by 20.19230769% intraday. The task is to link this movement to relevant news events. First, I need to check the recent news events listed. The user provided a long list, so I'll go through each one. The key here is to find news that's recent enough to impact the intraday price. Since the stock movement is intraday, the relevant news should have occurred on the same day or very close to it. Looking at the news titles and dates, the most recent one is from September 22, 2025, which mentions iBio announcing an amendment to a credit agreement with Woodforest. Wait, the date here is September 22, 2025, but the user's input seems to have a mix of dates. Wait, the current date in the example is 2025, but the user's input is in Chinese, which might be a mistake. Wait, the user might have a typo in the dates. Let me check again. Wait, the user's input has news events with dates ranging from May 2024 to September 2025. But the stock performance is "盘中 intraday" without a specific date. However, the most recent news is from September 22, 2025, and another on September 21, 2025. If the stock's intraday movement is on the same day as these news events, then those would be relevant. Looking at the first news event mentioned: "iBio Announces Amendment to Credit Agreement with Woodforest" on September 22, 2025. If the stock's intraday surge happened on that day, this could be the cause. However, the summary also mentions a surge of 50% after preclinical data on Amylin receptor antibody from June 24, 2025. Wait, that date is June 24, which is earlier than September. But the user's input says the stock performance is intraday, but the dates of the news are mixed. Wait, the user's input for the stock performance is "iBio盘中 intraday up 20.19230769%". The recent news includes an article from June 24, 2025, about a 50% surge after preclinical data. However, if the current intraday movement is on September 22, 2025, then the June news is old. But the user's input has a mix of dates. Wait, the user's input might have a formatting issue where the dates are not correctly ordered. Let me recheck. Looking at the user's input again: the first news event is titled "IBIO News Today | Why did iBio stock go down today?" with a summary mentioning a 50% surge after preclinical data on Amylin receptor antibody on June 24, 2025. Then, the next line says "content: iBio, Inc.: iBio Announces Amendment to Credit Agreement with Woodforest finanznachrichten.de - September 22 at 8:54 AM". Then another on September 21 at 5:42 PM. So, the most recent news is the credit agreement amendment on September 22, 2025. If the stock's intraday movement happened on the same day as that news, then that would be the relevant event. However, the summary mentions a 50% surge in June, which is prior. But the user's stock performance is a 20% increase intraday. The key is to find the most recent news that could have caused the current movement. So, the latest news is the credit agreement amendment on September 22, 2025. If the stock's intraday surge is on that day, then that news is the likely cause. However, the summary mentions a 50% surge after preclinical data, but that was in June. The other recent news includes a stock fall on August 15, a rise on August 14, etc. But the most recent positive news is the credit amendment on September 22. Therefore, the 20.19% intraday increase is likely due to the announcement of the credit agreement amendment with Woodforest on the same day. The other news about preclinical data is older and wouldn't affect the current intraday movement. The user's example in the instructions shows that the relevant news should be the most recent and directly related to the stock's movement. So, the answer should link the intraday surge to the credit agreement amendment announced that same day. The percentage is 20.19.
