Monolithic Power restates 2024-2025 financials due to $195M deferred tax error
------------------------------------------------------------------------------

- 2024 GAAP net income decreased by $195M to $1.592B; EPS diluted $32.60 vs. prev. $36.59.
- 2025 GAAP net income increased by $5.5M to $621.5M; EPS diluted $12.86 vs. prev. $12.75.
- Error is non-cash, no impact on revenue, non-GAAP net income, or business outlook for Q1 2026.
- Restatement stems from accounting for a foreign tax incentive; no misconduct involved.
- Previously issued 2024 10-K and 2025 quarterly reports should no longer be relied upon.
