WORK Medical shares surge 33.62% after-hours following $200 million sales agreement announcement.

think> Okay, let's tackle this query. The user wants me to act as a financial analyst explaining a stock price movement linked to news events. The stock is WORK Medical, which went up 33.624% after hours. I need to check the provided news events to see which ones are relevant. First, looking at the stock performance: it's after-hour trading with a significant increase. The recent news includes a strategic partnership with Shanghai Chartwell Medical Device Co., Ltd. on February 28, 2025. But wait, the current date in the input is December 2025. The latest news seems to be from December 3, 2025, about trading resuming and a halt. However, the most recent relevant news before the price movement might be the partnership announced in February. But that's several months old. Are there any newer news events? Looking through the list, there's a news item from December 3, 2025, stating that trading resumed after a halt. If the stock was halted and then resumed, that might explain volatility, but the price jumped up. However, the user mentioned the after-hour movement. The most recent news before the after-hour trade could be the resumption of trading. However, that might not be the cause of the 33.6% jump. Wait, there's also a news item from October 21, 2025, about WORK Medical making a $1M equity investment in Neologics Bioscience. Another one from November 4 about a service contract with GemPharmatech. But the biggest jump might be linked to a major partnership. The February 28 news about the strategic partnership with Shanghai Chartwell is mentioned, but that's old. However, maybe there's a recent similar partnership. Wait, checking again, the latest partnership mentioned is with Shanghai Chartwell on February 28, but if the current date is December 2025, that's several months prior. Maybe the user made a typo? Or perhaps the recent news is the one from December 3 about trading resuming. However, that might not directly cause a 33% jump. Wait, looking back, the first reason provided mentions the strategic partnership with Shanghai Chartwell, but the date is February 28, 2025. However, the stock price movement is in December 2025. That seems too old to be the cause. Unless there's a follow-up news. But in the provided news events, there's no newer partnership announced in December. The most recent relevant news might be the trading resumption. However, that's about trading halting and resuming, not a positive event. Alternatively, maybe the user intended that the latest news is the strategic partnership, but the date is a mistake. If the stock's after-hour jump is in December, but the partnership was announced in February, that's not the immediate cause. The other recent news includes a $2.9M registered direct offering in September, compliance with Nasdaq in November, and a reverse stock split in October. Wait, there's also a news item from October 21 about a $1M investment in Neologics Bioscience for 10% equity. That could be seen as positive, indicating expansion into AI medical tech. If that's recent and the stock was trading after hours, maybe that's the cause. However, the user's input lists that as Reason 2? Wait, no, the user provided two reasons. Let me check again. The input has two "Reason" sections. The first one includes the strategic partnership with Shanghai Chartwell (Feb 28, 2025) and other news up to December 2025. The second reason is from Yahoo Finance, mentioning some Chinese news unrelated. The key is to find the most recent news that would cause a 33.6% jump in after-hours trading. The latest news before the after-hour session would be critical. Looking through the list, the most recent positive news is from December 3, 2025, about trading resuming after a halt. However, that's about resuming trading, not a positive event. Wait, there's a news item from November 24, 2025, about entering a sales agreement to raise $200M. That's a significant funding raise, which is positive. If the stock moved after hours following that announcement, that could explain the jump. However, the user's input lists multiple news events. The challenge is to determine which one is the most relevant. Given the large percentage increase (33.6%), it's likely a major positive announcement. The partnership with Shanghai Chartwell (Feb 28) is old, but if there's a follow-up or if the user mistakenly listed the date, that could be it.
