Monolithic Power Systems said its audit committee concluded that its 2024 annual financial statements and its 2025 quarterly statements should no longer be relied upon because of an unintentional error in accounting for deferred income taxes tied to a one-time foreign tax incentive. The restatement cuts 2024 net income by $194.6 million to $1.592 billion, while 2025 net income rises $5.6 million, and the company says revenue, its non-GAAP measures and its Q1 2026 outlook are unchanged.
2024 net income restated to $1.592 billion from $1.787 billion; diluted EPS restated to $32.60 from $36.59.
