MONOLITHIC POWER SYSTEMS INC 8-K Report, Financial Restatement (Feb 27, 2026)

Filed February 27, 2026For Securities:MPWR

Summary

Monolithic Power Systems, Inc. (MPWR) has filed an 8-K report on February 27, 2026, announcing that its previously issued financial statements for the fiscal year ended December 31, 2024, and interim periods in 2025, should no longer be relied upon. This is due to an unintentional error related to the accounting for deferred income taxes associated with a foreign jurisdiction's tax incentive. The company emphasizes that this is a non-cash error and does not impact key operational metrics such as revenue, non-GAAP gross margin, non-GAAP operating expenses, non-GAAP net income, and non-GAAP diluted net income per share. The restatement primarily affects the "income tax benefit, net" and "deferred income taxes," resulting in a decrease of $195 million for the year ended December 31, 2024. The company will file its 2025 Form 10-K shortly to include these restated financials.
