Net cash used in investing activities was $76.5 million, including $71.9 million of property, plant and equipment purchases and $5.6 million for land-use rights. Financing activities provided $34.8 million; cash decreased by $25.9 million during the year. The company reported $69.4 million of unused borrowing capacity and said existing cash, operating cash flows and available credit should cover anticipated needs for the next 12 months. Debt agreements include financial covenants and secured assets; AOI reported compliance at year-end.
Fourth quarter: Revenue was $58.0 million, gross margin was 18.2%, operating loss was $12.3 million and net loss was $8.6 million. Gross margin fell from 31.1% in Q3 2018 and 40.3% in Q4 2017.
Material changes versus prior period
- Full-year revenue declined 30.0%, primarily because a major customer reduced purchases of 40 Gbps and 100 Gbps transceivers amid data-center architecture changes. Shipments to another customer were also curtailed in the second half amid concerns about failures in similar 100 Gbps products.
- Data-center revenue fell 34.7% to $200.2 million; CATV revenue fell 14.9% to $51.7 million. Telecom revenue increased 2.0% to $13.2 million, while FTTH remained small at $0.8 million.
- Gross margin declined 10.7 percentage points. Management cited lower capacity utilization, increased quality testing, reduced production and temporarily lower yields related to the transceiver quality investigation.
- Operating expenses rose 24.2% to $98.5 million. R&D increased 41.1% to $49.9 million, as AOI invested in data-center, CATV Remote-PHY, telecom and other products.
- Operating cash flow fell to $14.0 million, with cash use from higher inventory and lower accounts payable partly offset by non-cash charges and collections of receivables. Inventory rose to $93.3 million from $75.8 million; the 2018 excess-and-obsolete inventory reserve was $7.2 million.
- Debt increased, while year-end cash declined. The company repaid its $23.1 million revolving bank line on January 3, 2019.
Outlook, risks and unusual items
- Management expected continued sales of 40 Gbps and 100 Gbps products in 2019, with 100 Gbps sales likely to exceed 40 Gbps sales. It cautioned that quarterly results could vary considerably during the technology transition and that customers had greater near-term demand uncertainty.
- AOI expected broader CATV Remote-PHY deployment in 2019 after initial revenue in 2018. It also expected to begin selling products for advanced 5G networks in 2019. These are expectations, not guaranteed outcomes.
- Customer concentration is substantial: Facebook, Microsoft and Amazon represented 38.3%, 22.1% and 12.1% of 2018 revenue, respectively; the top ten customers represented 92.9%. Customer orders are generally short-term purchase orders that may be changed or cancelled.
- Product reliability is a material execution risk. AOI reported reduced 100 Gbps shipments after customer concerns about failures of similar products and incurred added testing costs. Separate shareholder litigation followed disclosures concerning 25G laser issues; the company disputes the allegations. Another securities class action and consolidated derivative litigation related to earlier disclosures remained pending as of the filing.
- Other significant risks include competitive pricing, demand and product-mix volatility, supply constraints, high fixed manufacturing costs, China/Taiwan operating exposure, U.S.–China tariffs, foreign-exchange movements, and reliance on the Sugar Land facility for proprietary laser fabrication.
- 2018 included a $7.6 million income tax benefit despite a pretax loss, including a $1.8 million favorable adjustment to the Tax Act transition-tax estimate. Government subsidies and foreign-exchange gains also contributed to other income. China’s preferential 15% tax rate was approved through November 2020, subject to qualification.
- AOI was constructing a new Ningbo factory, with estimated contract costs of approximately $27.5 million and completion expected in early 2020. About $8.2 million had been incurred by year-end. The company also expected adoption of lease accounting in 2019 to add approximately $10.3 million of operating lease liabilities and $9.3 million of right-of-use assets.
Most important facts for investors to verify
- Whether major data-center customers resume or expand orders, and whether customer architecture changes further reduce transceiver demand.
- Whether the 100 Gbps quality issue is resolved, shipments recover, and related testing, warranty or remediation costs remain manageable.
- Whether gross margins recover from the 18.2% reported in Q4 as production volumes, yields and capacity utilization change.
- Whether operating cash generation improves and inventory levels and reserves are appropriate amid lower revenue and high planned investment.
- Debt balances, facility availability, covenant compliance, and the effect of the January 2019 repayment and subsequent credit amendments on liquidity.
- Progress, total cost and expected return of the Ningbo factory expansion, alongside management’s 2019 product and market expectations.
- Developments and potential exposure in the pending securities and derivative litigation, as well as the effects of tariffs, currency changes and the China tax preference.
