AI brief of an SEC Form 8-K · Monolithic Power Systems (MPWR)

Monolithic Power Systems restates 2024 results, cutting tax benefit by $195 million

Mixed Impact 5 of 5 earnings Written later

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.

Key points

  • 2024 net income restated to $1.592 billion from $1.787 billion; diluted EPS restated to $32.60 from $36.59.
  • The error relates to deferred income taxes on a one-time tax incentive granted by a foreign jurisdiction; the company says it is non-cash and involved no misconduct.
  • 2025 net income increases $5.6 million to $621.5 million; diluted EPS rises to $12.86 from $12.75.
  • Revenue and non-GAAP measures are unaffected, and the Q1 2026 business outlook from February 5, 2026 is unchanged; the 2025 Form 10-K will be filed immediately after this 8-K.
