Record orders and backlog growth continue with Q3 book-to-bill significantly greater than 1x, and one month into Q4 orders nearly equal to all of Q3. Demand visibility extends into 2028 with backlog expected to exceed $10 billion at fiscal year-end.
Guidance · revenue to $8.35B
Book-to-bill was 'significantly greater than 1', leading to an $800M increase in backlog to $8.5B, with expectations to grow to over $10B by fiscal year-end.
AI-driven demand is accelerating and is the primary driver of optical connectivity growth across WAN, AI WAN, and data center markets, with management expecting the TAM to double by 2029 and positioning co-packaged optics and coherent technology to monetize AI infrastructure.

Management has secured incremental supply capacity and made capital investments to support over 60% revenue growth in RLS, plug, and wave server products, with capital expenditures expected at the high end of $250-275 million range.
Management expressed strong confidence in multi-year growth driven by AI, citing record backlog and robust demand, while emphasizing supply constraints as the main limit to even higher growth.
Supply constraints cap near-term revenue and extend backlog, but long-term agreements aim to secure capacity through 2029, supporting future growth.
“It would be greater than that if supply was greater.”
Capacity investments are necessary to convert strong order flow into revenue; delays in qualification and expansion could impact fiscal 2027 upside.
“We continue to invest upstream to drive security of supply to meet and eventually bring into balance the demand backlog.”
“we finalized long-term agreements that secure supply of certain key components through 2029, including incremental capacity for those key components that will enable us to support growing customer demand.”
“the vast majority of that $10 billion comes with a customer request date that's actually in 27, meaning that they would take it if we could give it to them. So to your question, the backlog covers most of the 27 guide.”
“we've gotten to a space where we would expect, depending on the customer and the product line, anywhere between high single digits types of price increases to something in the range of high teens, low 20s type of price increases.”
“just one month into this quarter, we are approaching a level of orders booked equal to the entirety of Q3.”
“we're on track for, you know, getting that product to standardization by the end of, you know, this calendar year. And you'll see the ramp starting in 27. And that ramp in 27 will be to several hundred million dollars, right?”

Management successfully negotiated price increases of high single digits to high teens/low 20s, which will selectively hit backlog, and is restructuring commercial terms to align demand with supply capacity. — Pricing power is a strong indicator of market tightness and is a key driver margin expansion to record levels.
Great. And as a quick follow-up, on scale across, I mean, to what extent is that, you know, maybe even the primary driver of growth in 27? And I'd be interested in your reaction to some pretty extraordinary comments from suppliers and competitors about dynamics and scale across. I think Cisco talking about 14x the port count versus traditional DCI and some pretty spectacular comments from Lumensum as well. You know, maybe we can sharpen the focus on the scale across opportunity, how you see that, Tam, having maybe increased in recent quarters. And thanks again.
