Financial performance
| Metric | FY2023 | FY2022 |

| Revenue | $444.5 million | $651.1 million |
| Gross profit / margin | $229.0 million / 51.5% | $366.9 million / 56.3% |
| Operating expenses | $193.9 million | $186.5 million |
| Operating income | $35.1 million | $180.4 million |

- Revenue fell approximately 31.7%; net income fell approximately 67.4%. Gross margin declined 4.8 percentage points.
- Management attributed weaker sales across all four end markets to semiconductor-cycle inventory correction and macroeconomic and geopolitical pressures, including inflation, higher interest rates, softer housing, weaker mobile-phone demand and economic weakness in China.
- Gross margin was pressured by lower production volumes and a less favorable end-market mix. Operating expenses rose $7.4 million, mainly on higher stock-based compensation, salaries and benefits.
- Other income rose to $10.8 million from $3.0 million, primarily due to higher investment yields. The $9.8 million income-tax benefit included a $7.6 million release of uncertain-tax-position reserves; the effective tax rate was negative 21.4%, versus 6.9% in 2022.
Liquidity, cash flow and capital allocation
- Cash, cash equivalents and short-term marketable securities totaled $311.6 million at year-end, versus $353.8 million in 2022. Working capital was $462.7 million, compared with $466.7 million.
- Operating cash flow was $65.8 million. Inventory increased $27.7 million, partly reflecting softening demand. Investing activities used $14.2 million, including $20.9 million of capital expenditures.
- Financing activities used $93.0 million, including $55.3 million of share repurchases and $44.0 million of dividends. The company repurchased approximately 0.8 million shares in 2023; $26.0 million remained authorized at year-end.
- No borrowings were outstanding under the $75 million revolving credit facility, which matures June 7, 2026. The company reported compliance with its covenants and stated that existing liquidity and expected operating cash generation should cover requirements for at least 12 months.
- There is no reported funded debt outstanding. Other commitments include $41.6 million of purchase obligations due within one year and $11.2 million of undiscounted operating lease payments.
Outlook, risks and unusual items
- No specific revenue or earnings guidance is provided. Management expects FY2024 capital expenditures to be primarily for production machinery and equipment, funded with cash on hand and future operating cash flow.
- Key risks include uncertain, cancellable customer orders; distributor-channel exposure; customer concentration; intense pricing competition; and reliance on three wafer foundries. The earliest cited wafer-supply agreement expires in December 2025; qualifying an alternative source could take 12–24 months.
- Concentration is notable: the top ten customers represented 80% of 2023 revenue; Avnet accounted for 27%, Honestar for 18%, and Salcomp for 10%. International sales were 98% of revenue, and Asia represented approximately 84%.
- Two patent matters remained unresolved. The company said outcomes cannot be predicted and it could not estimate a loss or range of loss. Adverse outcomes could involve damages, licensing costs or restrictions on product sales. The filing also identifies ongoing California tax audits for 2018 and 2019.
- Inventory valuation is a significant estimate and was identified as a critical audit matter. Inventory rose to $163.2 million from $135.4 million; additional write-downs could affect cost of revenue if demand or market conditions worsen.
- The financial statements received an unqualified audit opinion, and management and the auditor concluded internal control over financial reporting was effective as of December 31, 2023.
Most important facts for investors to verify
- Whether demand and distributor inventories are recovering, and whether rising inventory leads to further production cuts or obsolescence charges.
- Whether margins can stabilize as production volumes and end-market mix change, including the effects of competition and yen-linked wafer costs.
- Customer concentration and order variability, particularly exposure to Avnet, Honestar and Asian manufacturing markets.
- Developments and potential costs in the CogniPower and Waverly patent disputes, plus the California tax audit.
- Cash generation and capital returns relative to the reduced earnings base, planned 2024 capital spending and continued dividend commitments.
