Monolithic Power Systems declared that investors should no longer rely on its 2024 audited financial statements and 2025 quarterly results because of an unintentional tax accounting error tied to a one-time foreign tax incentive. The issue is non-cash, affects only income tax accounting, and involved no misconduct.
For 2024, the restatement reduces the income tax benefit and deferred taxes by about $195 million, lowering net income to $1,592 million. Non-GAAP metrics such as revenue, non-GAAP gross margin and non-GAAP net income are unchanged.
For 2025, the adjustment decreases income tax expense by $5.5 million, increasing net income by the same amount. The company says its business outlook for the quarter ending March 31, 2026 remains intact and will include the restated figures in its 2025 Form 10-K.
