Silicon Laboratories Inc. — FY2013 Form 10-K
Reporting period: Fiscal year ended December 28, 2013 (52 weeks). The filing also reports fourth-quarter results and compares them with Q4 2012; it is not a 2012 Q4 filing. Amounts are in U.S. dollars.
Business context and financial performance
Silicon Laboratories designs mixed-signal integrated circuits and operates as a fabless semiconductor company, relying on third parties for wafer fabrication, assembly and testing. Its products span broad-based, broadcast and access categories. Revenue is highly international: 88% came from outside the United States in FY2013.

FY2013 revenue by product category was $281.8 million broad-based (+4.3%), $199.8 million broadcast (+7.4%) and $98.5 million access (-8.1%). Broad-based growth reflected acquisitions and timing-product share gains; broadcast growth was led by video ICs. Access and broadcast audio weakness reflected market-share declines. Unit volume fell 8.1%, while average selling prices rose 12.1%.

Quarterly cash flow is not provided in the supplied filing text. FY2013 operating expenses rose 14.4% for R&D and 14.3% for SG&A, outpacing revenue growth and contributing to lower annual operating income. R&D spending was $157.8 million (27.2% of revenue). The effective tax rate fell to 19.7% from 26.4%, principally reflecting recognition of federal R&D tax credits and comparison with a prior-year tax charge.
Liquidity, debt and capital allocation
- At year-end, cash and cash equivalents were $95.8 million and short-term investments were $179.6 million; an additional $10.6 million of long-term investments comprised illiquid auction-rate securities.
- Long-term debt was $95.0 million, including $7.5 million current and $87.5 million non-current. The company had not drawn on its $130 million revolving facility and reported compliance with its credit covenants.
- The term loan is due in 2017; an interest-rate swap fixed the LIBOR component through maturity. The reported combined loan rate was 2.514% at year-end.
- Operating cash flow was $120.2 million; investing activities used $105.9 million and financing activities used $23.9 million. The company spent $26.0 million repurchasing shares in FY2013 and had authorized a $50 million buyback program through January 2014.
- Management expected FY2014 capital expenditures of $10–$14 million and stated that available liquidity and credit were expected to cover requirements for at least 12 months.
Outlook, material events and risks
- Guidance: For Q1 FY2014, management forecast revenue of $142–$146 million and diluted EPS of $0.14–$0.18. R&D expense was expected to remain relatively stable in absolute dollars; SG&A was expected to increase. Management expected the FY2014 effective tax rate to rise, primarily because the federal R&D tax credit had expired at year-end 2013. FY2014 was to have 53 weeks.
- Acquisition: Silicon Labs acquired Energy Micro on July 1, 2013 for approximately $140.6 million, including cash, stock/deferred consideration and contingent earn-out consideration. The purchase price included $98.5 million of goodwill, which is not tax deductible. Earn-out payments depend on product revenue growth and may reach approximately $33.3 million. Purchase-price allocation was preliminary.
- Supply: A wafer supplier for high-voltage products entered insolvency proceedings in 2013; its former foundry was acquired by Donauplaza, whose operating ability was unproven. Silicon Labs held additional inventory and was qualifying an alternative supplier. TSMC or its affiliates manufactured most wafers, creating supplier concentration.
- Legal: Cresta Technology filed patent litigation and an ITC complaint in January 2014 concerning TV tuner products, seeking unspecified damages and an import/sales exclusion. The company said it would defend the claims and could not estimate the outcome or financial impact. Separately, the MaxLinear disputes were settled in October 2013 through cross-licenses, dismissal of cases and a $1.25 million payment to Silicon Labs.
- Other notable exposures: $12.4 million par value of auction-rate securities remained subject to failed auctions, with maturities from 2033 to 2046; the company could not predict when principal would become accessible. Other key risks include customer and distributor concentration, cancellable purchase orders, price erosion, semiconductor cyclicality, qualification delays, inventory obsolescence, dependence on Asian manufacturing and testing, IP claims, and acquisition integration and contingent-payment estimates.
- The ten largest end customers represented 41% of FY2013 revenue; Samsung represented 15%. Distributors Edom Technology and Avnet represented 21% and 11%, respectively. No cash dividends were paid, and management said none were intended in the foreseeable future.
Most important facts for investors to verify
- Whether the Q1 FY2014 revenue and EPS guidance was achieved, and whether full-year performance followed the expected tax and expense trends.
- Whether the Energy Micro acquisition delivered the anticipated growth and product integration, and how contingent consideration and goodwill estimates evolved.
- Progress in replacing or securing supply from Donauplaza and the continued availability of TSMC capacity.
- Developments, potential costs or sales restrictions from the Cresta patent cases and any other IP disputes.
- Revenue and margin trends in access products, broadcast audio and other areas with reported market-share losses, alongside the sustainability of ASP increases.
- Liquidity and debt obligations, the recoverability and timing of auction-rate securities, and the effect of customer, distributor and supplier concentration.
