AI-Friendly Integrated Report Ranking 2025

Sustainable Lab, based in Chiyoda, Tokyo, has publicly released its AI-Friendly Integrated Report Ranking for 2025, which rates the integrated reports of companies listed on the Tokyo Stock Exchange using a unique metric for AI readability. The report emphasizes the increasing importance of AI in analyzing corporate ESG (Environmental, Social, and Governance) data, allowing investment analysts and institutions to extract relevant insights efficiently.

In this evaluation, the top three companies recognized for their AI-friendly reports are:
1. Toyota Motor Corporation
2. Panasonic Holdings Corporation
3. Tokyu Construction

Context

With the growing complexity of ESG disclosures, the volume of information in integrated reports has been increasing each year. However, there remains a challenge in the number of hours investors, analysts, and rating agencies can allocate for review. This has driven the necessity for better-designed information architectures that facilitate collection and analysis by machines, including AI and data crawlers. Recognizing that integrated reports must serve not only human readers but also machines, Sustainable Lab has focused on mechanical readability, providing insights into how companies can enhance their investment relations and overall market evaluation.

Evaluation Criteria

The ranking analyzed the integrated reports from the top 960 Tokyo Stock Exchange companies by market capitalization as of November 2025. The assessment criteria included a thorough evaluation of the latest accessible PDF reports:
Text Extractability
Table Readability
Logical Structure and Clear Headings
Navigation and Hyperlink Design
Paragraph Density and Redundancy
Summary and Dialogicity
Metadata and Technical Integrity
Consistency and Accessibility Aids

It’s important to note that this ranking focuses solely on the mechanical readability of integrated reports, without directly assessing the accuracy or comprehensiveness of the financial content or ESG performance disclosed by the companies.

Top 50 Rankings and Insights

The top companies in the AI-friendly report ranking showcased strengths primarily in text extractability, with 38 firms excelling, followed closely by table readability and navigation design, each with 34 companies rated positively. Notably, areas like logical structure, while still showing merit, revealed room for improvement with only 27 companies achieving favorable ratings.

The rankings indicated that there’s significant potential for enhancements in sectors identified as lacking, such as paragraph density and summary functionality. Certain industries, particularly Information Communications and Electronics/Precision, exhibited a higher concentration of companies in the upper echelons of the AI-friendly rankings.

Practical Implications for Companies

Improving mechanical readability can often be achieved with minor adjustments during the PDF creation process. Here are some actionable steps companies can take:
1. Minimize Image Text Use: Simplifying documents by retaining text layers will make content searchable and copyable.
2. Structure Tables: Clearly defining cell boundaries and header rows will facilitate better navigation by AI systems.
3. Clarify Heading Hierarchies: Consistently applying header levels (H1, H2, H3) provides clarity and enhances user experience.
4. Design Links for Navigation: Creating interactive elements like PDFs bookmarks and index links can significantly improve usability.
