Safe & Green shares surge 20.37% intraday after Olenox subsidiary secures DOT approval to restart oilfield services with proprietary plasma and ultrasonic cleaning technologies.

think> Okay, let's tackle this query step by step. The user wants me to transform a given Chinese text into a concise news headline following specific rules. First, I need to understand the input thoroughly. The company name is Safe & Green, and there's a 20.37230769% increase during intraday trading. The reasons provided are two points: one about a subsidiary getting a DOT approval and another about plans to restart the oilfield services business. I need to make sure the company name stays exactly as is. The percentage should be rounded to two decimal places, so 20.37%. The time period is intraday. The reason should include both the approval and the business restart plan. The example output uses a structure where the headline starts with the company name, the percentage change, time period, and the reason. I should follow that structure. Now, translating the reasons into English. The first point mentions Olenox, a subsidiary, getting DOT approval on November 25, 2025, allowing transport of oilfield equipment. The second point is about restarting the oilfield services business, serving their own wells and selling to third parties using proprietary technologies like plasma pulse and ultrasonic cleaning tools. I need to condense these points into a brief reason. Maybe combine the approval and the restart plan. Also, check if the date format is correct—November 25, 2025. The example uses "has signed an agreement," so past tense for the approval. The company's plan is in the future, so "plans to restart." Also, mention the proprietary technologies in the reason. Putting it all together: Safe & Green surged 20.37% intraday, with its subsidiary Olenox receiving DOT approval to transport oilfield equipment, enabling the restart of its oilfield services business. The company plans to serve its own wells and sell services to third parties using proprietary plasma pulse and ultrasonic cleaning tools. Check if all elements are included: company name, percentage, time period, reason. Rounded percentage is correct. Time period is intraday. The reasons include the approval and the business plan with tech. Looks good. Avoid trailing zeros, so 20.37% is correct. No markdown, just plain text. The example also includes a line break, but maybe the user wants a single paragraph. Wait, the example has a line break after the first sentence. Let me check the example again. Yes, the example has a line break after the first sentence, then the company description. But in the user's transformation rules, the example shows two paragraphs. However, the user's instruction says "concise news headline," which might imply a single line. But the example shows a paragraph split. Hmm. The user's example includes a line break, so maybe I should follow that. But the user might not need that. Wait, the example's output is two paragraphs. The first part is the headline with the key info, and the second part is the company description. However, the user's query here is to transform the text into a headline, which includes the reason. So perhaps the example is structured as two parts, but the user wants a single headline. However, the example shows two paragraphs. Let me check the rules again. The rules say: "Provide a brief reason for the price movement, retaining key information." So the headline should include the reason. The example does that by including the reason in the first sentence. Then the second part is more about the company's focus. But in the current input, the user's example output is two paragraphs. However, the user's instruction says "concise news headline," which might be a single line. But the example shows two. Maybe the user wants the headline to be the first sentence, and the rest as supporting details. But the example includes both in the output. Let me check the example again. In the example input, the output is two paragraphs. The first paragraph starts with the company name, percentage, time, and the reason. The second paragraph is the company description. So perhaps the user wants a similar structure: a headline with the key info and a brief reason, followed by a paragraph about the company. However, in the current query, the user's example is part of the input, and the output is structured as two paragraphs. But the user's current input might not have the company description part. Let me look at the current input. The current input is about Safe & Green and their reasons for the price movement. The user hasn't provided a company description beyond the two points. So the output should include the headline with the key info and the reason, which includes the two points. The example output includes the company's focus in the second paragraph. But in the current input, the user hasn't provided that info. Wait, in the current input, the user's example includes a company description in the input. The current input here doesn't have that.
