Period Ended: March 31, 2008
Business Overview: MPS is a fabless semiconductor company designing, developing, and marketing high-performance, mixed-signal analog semiconductors for computing, consumer electronics, and wireless markets. The company operates in a single reportable segment.
Restatement Notice: This filing includes a restatement of the prior year's (Q1 2007) financial statements due to a material error in the accounting for the tax effect of stock-based compensation related to a cost-share agreement with a foreign subsidiary. This error resulted in a material weakness in internal controls over financial reporting.

Material Changes vs. Prior Period
- Revenue Growth: Revenue increased 44.6% year-over-year to $35.4 million, driven by a 51.6% increase in DC-to-DC converter sales, a 19.7% increase in LCD backlight inverter sales, and a 63.8% increase in audio amplifier sales.
- Profitability: The company returned to profitability with net income of $5.9 million, compared to a net loss of $0.3 million in the prior year. This improvement was aided by a significant reduction in litigation expenses.
- Operating Expenses:
- R&D: Increased 27.7% to $7.6 million due to increased headcount and new product development.
- SG&A: Increased 40.8% to $8.7 million due to headcount growth, bonuses, and higher stock-based compensation.
- Litigation: Provision for litigation expense decreased 74.1% to $0.7 million from $2.8 million, reflecting reduced activity following settlements in 2007.
- Stock Repurchases: The company initiated a stock repurchase program, spending $9.5 million to repurchase 554,832 shares in Q1 2008.
Outlook, Risks, and Contingencies
Management Commentary and Guidance
Management expects operating results to fluctuate due to the cyclical nature of the semiconductor industry, litigation outcomes, and the timing of new product introductions. No specific quantitative guidance for future quarters was provided in this text.
Material Risks and Contingencies
- Patent Litigation:
- O2 Micro, Inc.: Ongoing appeals regarding the '722 patent (jury previously ruled in MPS's favor) and a new counterclaim regarding the '129 patent. MPS has posted $8.0 million in cash bonds in Taiwan related to counter-injunctions; forfeiture could materially impact results.
- Linear Technology: Trial scheduled for June 23, 2008, regarding alleged patent infringement. Loss probability and range are currently indeterminable.
- Taiwan Sumida Electronics (TSE): Settled for $2.5 million upfront with an additional $7.4 million held in escrow contingent on legal outcomes.
- Investment Liquidity: $39.1 million in auction-rate securities are currently illiquid. While credit quality remains AAA, the company recorded a $0.4 million temporary impairment. Continued auction failures could negatively impact liquidity and portfolio value.
- Internal Controls: A material weakness exists regarding the calculation of tax effects for stock-based compensation. Remediation efforts are underway, including hiring external tax advisors.
- Geographic Concentration: 89% of revenue is derived from customers in Asia, exposing the company to political, economic, and regulatory risks in that region.
Investor Verification Checklist
- Restatement Impact: Verify the full extent of the restatement on prior periods and the status of the remediation plan for the material weakness in internal controls.
- Litigation Exposure: Monitor the status of the O2 Micro appeals and the Linear Technology trial (June 2008), as adverse outcomes could result in injunctions or significant damages.
- Auction-Rate Securities: Assess the liquidity risk of the $39.1 million investment in auction-rate securities and the potential for further impairments if auctions continue to fail.
- Customer Concentration: Review the dependency on top distributors (approx. 40% of revenue) and the impact of the O2 litigation on key customers in the LCD backlight market.
- Stock Repurchase Program: Track the remaining authorization ($15.5 million) and the company's execution of buybacks to support share price.
