Renesas Electronics reported robust non-GAAP results for the fourth quarter ended December 31, 2025, with revenue of ¥350.9 billion, gross profit of ¥207.9 billion (59.3% margin), operating profit of ¥108.0 billion (30.8% margin) and profit attributable to owners of the parent of ¥90.0 billion. EBITDA reached ¥127.8 billion (36.4% margin). On an IFRS basis the quarter saw revenue of ¥351.5 billion, gross profit of ¥207.3 billion (59.0%), operating profit of ¥67.2 billion (19.1%), profit attributable of ¥17.3 billion and EBITDA of ¥113.0 billion (32.2%). For the full year, non-GAAP revenue was ¥1,318.5 billion, gross profit ¥759.9 billion (57.6%), operating profit ¥386.9 billion (29.3%), profit attributable ¥329.3 billion and EBITDA ¥464.1 billion (35.2%). IFRS revenue totaled ¥1,321.2 billion, gross profit ¥753.8 billion (57.1%), operating profit ¥201.2 billion (15.2%), a loss attributable of ¥51.8 billion and EBITDA of ¥389.8 billion (29.5%).

The gap between non-GAAP and IFRS results primarily reflects amortization of purchased intangibles (¥111.4 billion for the year), stock-based compensation (¥37.1 billion) and other non-recurring adjustments (¥39.9 billion). Non-GAAP gross margin outperformed IFRS by 0.5 percentage points in Q4 and 0.5 for the full year, driven by exclusion of ¥2.7 billion in non-recurring revenue and amortization adjustments. Non-GAAP operating margin exceeded IFRS by 11.7 points in Q4 and 14.1 for the year, reflecting the same reconciliation items plus ¥7.4 billion of other non-recurring expenses in the quarter and ¥39.9 billion for the year.

Full-year revenue of ¥1,321.2 billion was 2.0% below 2024, led by a market softening in Automotive products partially offset by Industrial and Infrastructure growth. Operating profit decreased 9.8% year-on-year to ¥201.2 billion IFRS, while profit attributable swung from ¥219.1 billion in 2024 to a loss of ¥51.8 billion. The swing reflects a ¥236.6 billion foreign-exchange and asset-conversion loss related to the restructuring support agreement with Wolfspeed, increased SG&A expenses and other one-time charges.

Renesas’ strong non-GAAP profitability underscores its operational resilience in a cyclical semiconductor market, but the substantial IFRS loss spotlights balance-sheet volatility from strategic asset conversions and currency swings. Investors should weigh the underlying cash-flow strength—¥464.1 billion EBITDA—against one-off costs totalling over ¥388 billion, and monitor Automotive end-market demand shifting in 2026 alongside potential restructuring benefits from the Wolfspeed agreement.
