Margins and earnings. Gross margin improved mainly from a more favorable end-market mix and manufacturing efficiencies. Operating expenses rose to $49.6 million from $44.2 million, principally due to higher headcount, compensation and product-development costs. The effective tax rate was 10.4%, versus 2.4%; the prior-year rate benefited from discrete tax items as well as lower-tax jurisdictions and research credits.
Cash, liquidity and debt. At March 31, 2022, cash and cash equivalents were $170.6 million and short-term marketable securities were $273.4 million, totaling $444.0 million, down $86.4 million from year-end. Working capital was $523.3 million, down from $614.5 million. The company had no borrowings outstanding under its $75 million revolving credit facility, which matures June 7, 2026. Operating cash flow was supported in part by collections reducing accounts receivable; inventory increased $3.8 million. Cash flow after property-and-equipment purchases was approximately $59.9 million.
Material changes and business drivers
- Revenue increased despite lower communications sales: communications represented 26% of revenue, compared with 38% a year earlier. Consumer, industrial and computer applications increased; consumer and industrial represented 35% and 29%, respectively.
- International sales were 96% of revenue. Asia accounted for 80%; sales to distributors were 75%.
- Customer concentration remained significant: the top ten customers generated 77% of revenue. Avnet represented 31% and Honestar Technologies 16%.
- Share repurchases totaled $134.7 million for 1.58 million shares, and dividends paid were $10.7 million. The quarterly dividend was raised to $0.18 per share. The board authorized a further $75 million of repurchases in April, after quarter-end.
- Accumulated other comprehensive loss increased by $4.4 million, including $4.2 million of unrealized losses on marketable securities, primarily attributed to interest-rate changes. Management said it did not intend, and was unlikely to be required, to sell the affected securities before recovery.
Outlook, risks and unusual items
The filing provides no specific numerical revenue or earnings guidance. Management expects existing cash generation and liquidity to cover working-capital and other cash needs for at least the next 12 months, and said it intends to continue investing in R&D and capital-return programs, subject to business conditions and board discretion.
Management cited unpredictable customer ordering, cancellations and rescheduling, demand and pricing pressure, competition, and reliance on third-party wafer suppliers. COVID-19-related restrictions had caused temporary shutdowns at some assembly and test subcontractors; management said mitigation measures had prevented material effects to date, but renewed restrictions remain a supply-chain risk. The San Jose headquarters reopened on April 4, 2022.
Two supplier agreements share certain Japanese-yen exchange-rate effects; management estimated that a 10% U.S.-dollar/yen movement could change gross margin by approximately 1.0%, all else equal. The company also faces ongoing patent litigation involving Opticurrent and CogniPower. A prior Opticurrent case included a reduced $1.2 million damages award; an appeal was denied in February 2022, and the company stated it could not estimate a loss or range for the ongoing litigation. The company intends to continue defending the cases.
The company reported effective disclosure controls and no material change in internal control over financial reporting during the quarter. The filing states that risk factors had not changed substantively from the 2021 Form 10-K.
Important facts for investors to verify
- Whether the margin improvement and stronger demand in consumer and industrial markets persist, and how communications demand evolves.
- Customer and distributor concentration, particularly Avnet’s share of revenue and receivables, and the company’s limited direct visibility into end-customer demand.
- Wafer availability, subcontractor capacity and the impact of any renewed pandemic restrictions or other supply-chain disruptions.
- Future cash deployment: substantial Q1 repurchases and dividends reduced cash and securities; confirm the pace of repurchases, dividend sustainability and remaining authorization.
- Developments and potential financial impact of the Opticurrent and CogniPower litigation; the company says it cannot currently estimate a loss range.
- Interest-rate effects on available-for-sale securities and yen-related supplier costs; confirm subsequent fair-value and gross-margin effects.
