    「NSRP has remained in a negative net worth position since fiscal 2020 after reporting substantial operating losses in prior years due to low equipment utilization when commercial production began and the subsequent deterioration in product market conditions. Although equipment utilization remained high in the current fiscal year, NSRP reported an operating loss due to deteriorating product margins and continued to report a net loss, following the previous fiscal year, due to the impact of financial expenses associated with substantial borrowings.」

    Although equipment utilization was said to remain high, negative net worth since fiscal 2020, operating losses due to deteriorating product margins, and net losses due to substantial financial expenses have continued.
  2. 2026-05-12AdvancedEarnings presentation

    「25年度は、高稼働を継続し、タイムラグ及び在庫影響等を除けば営業段階では黒字であるが、金利負担が大きいため最終赤字 2030年頃の最終黒字化を目指す方針に変更無し」

  3. FY2025WorsenedAnnual report

    「NSRP has remained in a negative net worth position since fiscal 2020 after reporting substantial operating losses in prior years due to low equipment utilization when commercial production began and the subsequent deterioration in product market conditions. Although equipment utilization remained high in the current fiscal year, NSRP reported an operating loss due to deteriorating product margins and continued to report a net loss, following the previous fiscal year, due to the impact of financial expenses associated with substantial borrowings.」

    Although equipment utilization remained high, operating and net losses continued due to deteriorating product margins and financial expenses, and an allowance for doubtful accounts was recorded against the full amount of ¥53,913 million in long-term loans receivable.
  4. FY2024WorsenedAnnual report

    「Improving NSRP’s earnings (returning to profitability in fiscal 2025)」

    While setting a return to profitability in fiscal 2025 as a new earnings improvement target, NSRP continued to report operating and net losses during the fiscal year due to lower product margins, scheduled maintenance and substantial financial expenses, and also recorded an allowance for doubtful accounts against long-term loans receivable and other items in full.
  5. FY2023WorsenedAnnual report

    「NSRP had reported substantial operating losses in prior years due to low equipment utilization when commercial production began and the subsequent deterioration in product market conditions. In the current fiscal year, it reported an operating profit as product market conditions improved, but continued to report a net loss, following the previous fiscal year, due to the impact of financial expenses associated with substantial borrowings.」

    Although an operating profit was recorded as product market conditions improved, the net loss continued due to financial expenses associated with substantial borrowings, leaving challenges in making NSRP an earnings contributor.
  6. FY2023-Q2AdvancedAnnual report

    「Special gains and losses resulted in a gain of ¥17.4 billion, up 175.3% year on year, due to gains on the sale of fixed assets by domestic subsidiaries and a gain on the valuation of long-term loans receivable associated with Nghi Son’s return to profitability in Vietnam, despite a loss on a step acquisition arising from the conversion of Seibu Oil Co., Ltd. into a consolidated subsidiary.」

    For NSRP, after operating and net losses had continued through the previous fiscal year, a gain on the valuation of long-term loans receivable associated with its return to profitability was recorded for the six-month period ended the second quarter. This does not indicate that stable operations or earnings improvement had been fully achieved.
  7. FY2022WorsenedAnnual report

    「NSRP has reported operating losses continuously since the past, due to low equipment utilization when commercial production began and the subsequent deterioration in product market conditions. In the current fiscal year, although product market conditions and equipment utilization improved, it continued to report an operating loss and a net loss, following the previous fiscal year, and cash flow also deteriorated.」

    Although product market conditions and equipment utilization improved, operating and net losses continued, as did cash flow deterioration, deepening the challenge of making NSRP an earnings contributor and improving its earnings after the start of commercial operations.
  8. FY2021WorsenedAnnual report

    「Nghi Son continued to face difficult earnings conditions during the fiscal year due to the impact of the COVID-19 pandemic, but from fiscal 2021 onward we will continue working to improve earnings through stable operations, cost optimization and margin recovery.」
