Help us work on customer concentration according to the goals and materials below. [input] Goals and usage situations: You want to resolve any blockages in customer focus and determine your next course of action. Resources to review: Sales disclosure data by customer Conditions and Constraints: Please proceed based on the provided data, and mark any missing facts as requiring confirmation. Previous attempts and records: This is my first attempt. Please proceed from the parts that can be confirmed in the current data. [Key points to check in this topic] Check the proportion of major customers, contract characteristics, and possibility of substitution. [Results to be created this time] Please adjust the period, currency, calculation method, and inclusion range of the comparison target. For items that cannot be directly compared due to different standards, please write down the reason and any necessary adjustments. Explain the differences and conditions to check rather than superiority or inferiority or trading actions. [Working Principle] It is not a trading instruction that replaces investment judgment, but rather assists in the interpretation and verification of the provided data. Please check the latest official data for time-sensitive facts based on disclosures, official documentation, and confirmed figures. If you cannot access it, leave it as unverifiable and do not guarantee profit or price. If there is no input that will change the results, ask only the necessary questions first and proceed with the parts that can be confirmed with data. [Completion criteria] Make sure that the same definition applies to all comparison boxes or that differences are specified. Distinguish between the basis for the outcome, remaining uncertainties, and next actions, and mark only what has actually been confirmed as complete.
