WORK Medical shares rise 11.2% after-hours after announcing strategic partnership with Shanghai Chartwell Medical Device Co., Ltd.

think> Okay, let's tackle this query step by step. The user wants me to act as a financial analyst explaining the stock price movement of WORK Medical (WOK) based on recent news. The stock went up 11.2% in after-hours trading. First, I need to look through the provided news events to find the most relevant ones. The user mentioned two reasons, but looking at the input, there's a lot of news. The key here is to identify which news is recent and directly related to the stock's movement. Looking at the news, the most recent one before the price movement is the strategic partnership with Shanghai Chartwell Medical Device Co., Ltd. announced on February 28, 2025. However, the stock movement happened on December 13, 2025, so there's a time gap. Wait, the dates here are confusing. The news events listed go up to December 3, 2025, and the stock movement is after that. The latest news before the price movement would be December 3, 2025, which mentions trading resuming after a halt. But that's a neutral event. Wait, the user provided a lot of news from October 2024 up to December 2025. The stock movement is on December 13, 2025, after hours. The most recent relevant news would be the one on December 3, 2025, about trading resuming after a halt. But that's more about trading resuming, not a positive event. Looking further back, there's a news item on October 21, 2025, about a $1M investment in Neologics Bioscience. Another on November 24, 2025, about a $200M sales agreement. Also, on November 4, there's a service contract with GemPharmatech. But the stock movement is 11.2% after hours. Such a significant jump is usually due to a major positive news. The most recent positive news before December 13 would be the November 24th announcement of a $200M sales agreement. That's a substantial fundraising move, which could boost investor confidence. Alternatively, the partnership with Shanghai Chartwell on February 28, but that's much older. Wait, the user's input includes a news event titled "WORK Medical Technology Group (WOK) News Today" with a summary about the strategic partnership with Shanghai Chartwell. But the date on that news is February 28, 2025. If the stock movement is on December 13, 2025, then that news is over nine months old. That might not be the cause. Looking for news closer to December 13, there's a December 3, 2025, news about trading resuming after a halt. But that's not positive. The next is November 24, 2025, about the $200M sales agreement. That's a significant positive event. Also, on November 7, they regained Nasdaq compliance, which is positive. The 11.2% surge is likely due to the $200M sales agreement as it indicates the company is raising capital, which can be seen as a positive sign for growth and meeting regulatory requirements. The Nasdaq compliance on November 7 also helps, but the sales agreement is more directly tied to fundraising. So, the key news is the November 24th announcement. The stock movement happened in after-hours trading, so the news must have been released after the market closed. However, the user's input lists the November 24th news as from tipranks.com. I need to check if that news was released after the market close on December 13. Wait, the stock movement is on December 13, so the news causing it must be from that day or earlier. But the November 24th news is before that. Maybe there's another recent news. Wait, the user also mentioned "Reason 2" with a summary in Chinese about industrial AI cloud in Germany and NVIDIA. But that seems unrelated to WORK Medical. Given the data, the most plausible cause for the 11.2% after-hours surge is the recent news about the $200M sales agreement on November 24, 2025. However, if the stock movement is on December 13, and the news is from November 24, that's a bit old. Maybe there's a more recent event. Wait, looking again, there's a news on December 3, 2025, about trading resuming after a halt. If there was a halt and then resumption, sometimes the stock can gap up or down.
