through a special investigation committee's report that fictitious circular transactions had been conducted over a long period within the advertising agency business of its consolidated subsidiaries Biglobe Inc. and its subsidiary G-Plan Co., Ltd. Consequently, it was revealed that sales and cost of sales were overstated, and correction reports have been submitted retrospectively covering the fiscal years from March 2023 to March 2025. The internal control deficiencies identified include insufficient segregation of duties and inadequate development and operation of internal controls considering fraud risks.\n\n### Corrective Measures and Future Actions\nRecognizing the critical importance of internal control over financial reporting, KDDI has developed recurrence prevention measures based on the recommendations of the special investigation committee. These include strengthening vendor management, segregation of authority in procurement and proper management of inspection tasks, enhancing risk management for new business ventures, reinforcing audit functions and financial management, fostering ethical awareness, and reviewing management strategies aimed at strengthening group governance. The company intends to promote appropriate establishment and operation of internal controls.","jir_financial_highlights":"Correction of Sales and Cost of Sales: Unknown (Restated retroactively)\nPeriod of Corrected Internal Control Reports: Fiscal Year 39 (April 1, 2022 \u2013 March 31, 2023) to Fiscal Year 41 (April 1, 2024 \u2013 March 31, 2025) (Unknown)\nDate of Submission of Correction Reports: 2026-03-31 (Unknown)","jir_category":"","jir_hashtags":"#KDDICorporation, #disclosure_update, #JapaneseStocks","jir_key_figures":"Period of Corrected Internal Control Reports: Fiscal Year 39 (April 1, 2022 \u2013 March 31, 2023) to Fiscal Year 41 (April 1, 2024 \u2013 March 31, 2025)\nDate of Submission of Correction Reports: 2026-03-31\nTiming of Discovery of Fictitious Circular Transactions: Mid-December 2025 to Early January 2026","jir_meta_title":"KDDI Announces Correction of Past Internal Control Reports and Revenue Adjustment Due to Fictitious Circular Transactions","jir_meta_description":"KDDI confirmed fictitious circular transactions in the advertising agency business of its consolidated subsidiaries and retrospectively corrected sales and cost of sales for the fiscal years from March 2023 to March 2025.
