Does Carmichael have a track record of improving margins or operational efficiency in previous roles?

Based on the information you provided, the announcement only states that John Carmichael has been appointed President, North America of Kimberly‑Clark, effective September 15 2025. The release does not include any biographical details, prior work history, or specific achievements—such as improvements to profit margins, cost structures, or operational efficiency—that he may have delivered in earlier positions.

Therefore, with the current news excerpt alone, we cannot confirm whether Carmichael has a track record of:

• Boosting margins (e.g., higher gross, operating, or net profit percentages)
  
• Driving operational efficiency (e.g., cost‑reduction initiatives, productivity gains, supply‑chain optimization, or process improvements)
  

To assess his past performance in those areas, you would need additional sources that outline his previous roles (e.g., senior leadership positions at other consumer‑goods or manufacturing firms) and any publicly reported results or metrics tied to his leadership. If you can locate a more detailed biography, a prior press release, an investor presentation, or an SEC filing that lists his career highlights, those documents would typically contain the evidence needed to evaluate his historical impact on margins and efficiency.

In short: The provided news release does not contain enough information to answer the question about Carmichael’s track record on margin improvement or operational efficiency. Further research into his professional background would be required.
