Research and development expense increased 15.3% to $89.4 million, mainly from personnel-related costs, new product introduction and occupancy expenses. Selling, general and administrative expense was $44.9 million, roughly flat year over year. The effective tax rate was 35.7%, versus 33.8%.
Liquidity, debt and capital allocation
At April 1, 2023, cash, cash equivalents and short-term investments totaled approximately $1.152 billion ($716.4 million cash and $435.7 million short-term investments). The company reported $1.2 billion of these resources including rounding in MD&A. Working capital was approximately $767.4 million. Cash and cash equivalents increased $216.5 million during the quarter, mainly reflecting $254.3 million of investing cash inflows as securities were sold or matured; operating cash flow was negative.
The company had $535.0 million principal amount of 0.625% convertible notes, carried at $530.1 million net. The notes were classified as current after the company announced redemption for June 20, 2023, of notes not previously converted. Holders’ conversion right expired June 16, 2023. Principal is to be settled in cash; excess value may be settled in shares. The $400 million revolving credit facility was undrawn, and the company reported compliance with its covenants.
Inventory rose to $133.2 million from $100.4 million at year-end; days of inventory increased to 129 from 90. Accounts receivable was $87.7 million, with 32 days sales outstanding versus 25 at year-end. The company repurchased 95,000 shares for approximately $13.5 million during the quarter. Its repurchase authorization permits up to $500 million through December 2023.
Changes, outlook and material risks
Despite higher revenue, gross profit declined $1.9 million and gross margin fell 4.3 percentage points. Management attributed the margin decline to product pricing and costs, product mix, and demand and production-capacity conditions. Operating income fell to $19.6 million from $33.6 million; net income declined to $14.0 million from $22.9 million. Operating cash flow moved from $85.2 million provided to $13.3 million used, with working-capital changes including increased receivables and inventory among the factors described.
For fiscal Q2 2023, management forecast revenue of $238–$248 million, gross margin of 60%, operating expenses of approximately $131 million, an effective tax rate of 34%, and diluted EPS of $0.35–$0.45. It expected R&D and SG&A expense to remain relatively stable in absolute dollars.
Key risks include reliance on third-party manufacturing and assembly capacity, including geographic concentration and China-Taiwan geopolitical exposure; semiconductor cyclicality, inflation and interest-rate changes; customer and distributor concentration and inventory-return or price-protection arrangements; and product demand, pricing and qualification uncertainty. Two distributors each accounted for more than 10% of revenue; the two largest distributors together represented 53% of revenue. No individual end customer represented more than 10%. The company said 84% of revenue came from outside the United States.
The company disclosed an ongoing appeal of a Norwegian tax assessment of approximately 141.3 million kroner ($13.5 million) relating to 2013 intercompany pricing. Management believes its position is more likely than not to be sustained and says it has accrued adequate reserves, but an unfavorable outcome could materially affect the financial statements. Routine legal proceedings were not expected to have a material adverse effect.
