Montauk Renewables shares rise 11.54% intraday after subsidiary amends credit agreement to raise net leverage cap to 3.50.

think> Okay, let's see. The user wants me to transform the 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 Montauk Renewables having a 11.53846154% increase during intraday trading. The reason is a subsidiary amending its credit agreement by December 31, 2025, to raise the net leverage ratio to 3.50, which enhances financial flexibility. The example provided uses a similar structure, so I should follow that. First, the company name is Montauk Renewables. I need to keep it unchanged. The percentage is 11.53846154%, which should be rounded to two decimal places. Let me calculate that. 11.53846154 rounds to 11.54% because the third decimal is 8, which is 5 or above, so we round up the second decimal. So, 11.54%. Next, the time period is intraday, so I need to include "intraday trading" in the headline. The reason for the price movement is the subsidiary's credit agreement amendment. The key points are the date (2025-12-31), the action (amended credit agreement), the new leverage ratio (3.50), and the benefit (enhanced financial flexibility). I should phrase this concisely. Looking at the example, the structure is: Company surged X.XX% in [time period], with the company announcing... followed by the details. So the first sentence should include the surge and the main reason, then the second part can elaborate if needed. However, the user's example has two sentences in the output, but the rules mention a brief reason. Maybe I should keep it concise but include all necessary info. Also, the input has some formatting issues like numbers and Chinese characters, but I need to focus on the English parts. The number 1 before the reason might be a list item, but I can ignore that and just extract the info. Putting it all together: Montauk Renewables surged 11.54% in intraday trading, with the company announcing that its subsidiary amended its credit agreement by December 31, 2025, to increase the net leverage ratio to 3.50, enhancing financial flexibility. Wait, the example uses "announcing that its SunAtion subsidiary has signed..." so in this case, it's "its subsidiary amended...". The date is part of the announcement. I should include the date as part of the credit agreement amendment. The example also includes the date of the project start, so here the date is when the amendment was made (by December 31, 2025). But the date might be part of the agreement's terms, not the announcement date. The user's input says "于2025年12月31日签署信贷协议修正案", which translates to "signed the credit agreement amendment by December 31, 2025". So the amendment is to be signed by that date. I should mention that in the headline. So the final headline should be: Montauk Renewables surged 11.54% in intraday trading, with the company announcing that its subsidiary will amend its credit agreement by December 31, 2025, to increase the net leverage ratio to 3.50, enhancing financial flexibility. I think that covers all the required elements: company name, percentage, time period, and the reason with key details. The percentage is rounded correctly, and the time period is intraday. The reason includes the subsidiary action, the date, the leverage ratio change, and the benefit. The example also had a second paragraph explaining the company's focus, but the input here doesn't have that information. The user's example included a second paragraph, but the rules don't mention that. Wait, the example has two paragraphs, but the user's instruction says "a brief reason for the price movement". The example's first sentence is the headline, and the rest is the body. However, the user's instruction says "transform the following text into a concise news headline", which might mean just the headline. But the example output includes more than just a headline. Wait, the example's output is two paragraphs, but the prompt says "news headline". Maybe there's confusion here. The example's output is a headline followed by a paragraph, but the user's instruction says "a concise news headline that includes...". So maybe the user wants just the headline, but the example shows more. However, the rules mention "Please writing articles in English instead of other language", so perhaps the output is a full news article with a headline. But the example's output is two paragraphs. Let me check.
