Highlights

33% Revenue Growth: Reached a quarterly record of $526 million

2.5x Operating Profit: Rose to $127 million, with gross margin jumping to 34%

5x Silicon Photonics: Set a Q4 annualized target of $1.1 billion

Gross profit was $179 million, nearly double that of the same quarter last year. The growth engine is the infrastructure segment, particularly Silicon Photonics (SiPho). Customer prepayments surged to $341 million at the end of September from $27.5 million at the end of last year, and customer contracts are being extended through 2029.

Lowlights

Negative Free Cash Flow: Q3 recorded a deficit of $5.5 million

Cash from Prepayments: Operating cash flow of $185 million included $23 million in prepayments

Inventory Increase: Increased by $16.57 million in a single quarter to $263 million

Capital expenditures totaled $534 million for the nine-month cumulative period, significantly exceeding the $326 million recorded during the same period last year. If the expansion of new lines in Japan proceeds as planned, the investment burden is expected to continue for the time being. Q3 operating cash flow excluding prepayments was $162.3 million.

What the Company Said

Chief Executive Officer Russell Ellwanger stated that based on the Q4 guidance, the company is entering its strongest growth phase in history. He mentioned an annual revenue of $2 billion and a $2.4 billion annualized run rate for 2026, and also set a goal to avoid typical industry seasonality in Q1 2027.

Market Reaction and Future Outlook

The after-hours rise was driven by the Q4 revenue guidance of $600 million, which is a 14% increase from the previous quarter. The company's mention of avoiding seasonality in Q1 2027 alongside the extension of customer contracts through 2029 was interpreted as a signal of sustained growth.

It is necessary to confirm whether Q4 revenue actually falls within the $570 million to $630 million range.

The next key point to watch is how much the $1.1 billion annualized silicon photonics target is reflected in quarterly results.

As capital expenditures continue, we must monitor when free cash flow turns positive.
