Annovis Bio shares surge 10.16% intraday as company announces CTAD conference presentations and FDA Type C meeting for buntanetap's PDD clinical development.

think> Okay, let's tackle this query step by step. The user wants me to transform a given text into a concise news headline following specific rules. First, I need to make sure I understand all the requirements. The input is about Annovis Bio's stock surging intraday by 10.16056911%. The user provided two key points: a presentation at the CTAD conference and an FDA Type C meeting. The example given uses the company name, rounds the percentage to two decimals, includes the time period, and gives a brief reason. First, I'll check the company name: Annovis Bio. That's straightforward. The percentage is 10.16056911%, which needs to be rounded to two decimals. Rounding that gives 10.16%. The time period is intraday, so that's clear. Next, the reason for the price movement. The input mentions two announcements. The first is about two presentations at the CTAD conference in December 2025 regarding buntanetap's development for neurodegenerative diseases. The second is the FDA Type C meeting scheduled for January 2026 to discuss the clinical development path for PDD. I need to combine these into a brief reason. The example in the prompt uses "with the company announcing..." and includes both points. I should structure it similarly, ensuring key info is included without being too verbose. Also, the user mentioned to write the article in English, so the output should be in English. Let me verify the dates and events: CTAD conference is December 1-4, 2025, and the FDA meeting is January 2026. The drug is buntanetap, targeting neurodegenerative diseases and PDD. Now, putting it all together. The headline should start with the company name, the percentage change, the time period, and the reason. The example uses a sentence structure that first states the surge and then the reasons. I need to make sure the percentage is correctly rounded and formatted without trailing zeros. Since 10.16 is already two decimals, that's good. Check if there are any trailing zeros to remove. The original percentage is 10.16056911%, which rounds to 10.16%. No trailing zeros here. The time period is intraday, so "in intraday trading" is correct. For the reason, the two announcements should be mentioned concisely. The first is the CTAD conference presentations, the second is the FDA meeting. The example uses "announcing that" followed by both points. I can structure it as "announcing two presentations at the CTAD conference... and a Type C meeting with the FDA..." Also, the example in the prompt includes additional details in the second paragraph, but the user's rules state to keep it concise. Wait, looking back, the example output has two paragraphs. But the user's instruction says "a brief reason for the price movement". So maybe the second paragraph in the example is part of the brief reason, but perhaps the user expects the headline to be a single paragraph? Or maybe the example includes a continuation after the headline. The example's output has two paragraphs: the first is the headline, and the second is additional info. But the user's instruction says "a brief reason for the price movement", so maybe the headline should include both reasons in one sentence. Let me check the example again. In the example, the first sentence is the headline with the surge and the reason (the subsidiary's agreement). The second sentence gives more details about the project, and then the third sentence explains the company's focus. The user's instruction says "provide a brief reason for the price movement, retaining key information." So the main reason is the two announcements, and perhaps the additional details can be included but need to be concise. Therefore, the headline should start with the company name, percentage, time period, and the reasons. The example includes the key points in the first part, then more details. So perhaps the user expects the headline to be a single paragraph with the main reasons, and any additional info can be in a second paragraph if needed. However, the user's example shows that the output is a single paragraph, but the user's instruction says "a brief reason for the price movement." So maybe the entire reason should be in the first paragraph. Wait, in the example, the first paragraph is the headline with the surge and the reason, then the second paragraph is the company's focus. So perhaps the user wants the headline to include the surge and the two reasons, and then the company's focus as a separate paragraph. But the user's instruction says "a brief reason for the price movement," so maybe the two reasons are the brief reason. Therefore, the structure should be: [Company] surged [X.XX]% in [time period] trading, with.
