The news directly pertains to Calumet as it indicates the resumption of full operations at one of its key facilities, which had been operating at reduced capacity. This return to full operations is likely to have a positive impact on the company's production volume and efficiency, leading to potential increases in revenue. The absence of planned turnarounds for 2024 suggests operational stability, which is typically viewed favorably by investors. The confidence score is high due to the direct correlation between operational efficiency and financial performance, although it is not at 100 because the exact financial impact is not quantified in the news.
