FY2026 improved profitability via mix and utilization while management faced persistent laser/transceiver supply constraints and ramp gating.
Management repeatedly linked non-GAAP gross margin expansion to better manufacturing utilization, favorable product mix, and targeted price increases. The pattern strengthened into Q3 and Q4 as systems and component mix improved.
Across multiple quarters, laser chip and components revenue growth was central to results and guidance. Management described components as effectively sold out and used LTAs to support capital spending plans.
FY2026 started with record Q1 momentum, then broadened growth drivers through Q2 and Q3, ending with Q4 confirming optical-transition breadth and margin milestone progress.
Gross margin stepped up with utilization and pricing
The year progressed from record AI-led components execution and early transceiver layering to broader OCS and CPO confidence—ending with Q4 confirming margin milestones while high-powered laser supply remained the key limiter.
Management highlighted record Q1 revenue and margin expansion, attributing growth to AI demand across laser chips and optical transceivers. They guided to an accelerated Q2 revenue milestone while describing capacity yield improvements and still-widening supply-demand imbalance.
Read earnings transcriptQ2 extended revenue records and improved margin, with management pointing to OCS clearing an internal $10M target early and backlog surging past $400M. Transceivers moved closer to “sustained growth,” but supply constraints continued to shape timing and allocation.
Management provided detailed non-GAAP quarterly guidance ranges in Q1–Q3 and guided early into Q1; transcripts support timing confidence but do not fully quantify adherence across all metrics here.
Q2 net revenue in range $630M to $670M (midpoint ~$650M).; Q2 non-GAAP operating margin 20% to 22%.; Q2 diluted net income per share $1.30 to $1.50.
Revenue $665.5M; EPS $0.89
Q2 revenue landed near the guide high end, but EPS comparison is difficult because reported EPS values provided are inconsistent with non-GAAP framing across the inputs.
Q3 net revenue range $780M to $830M (midpoint $805M).; Q3 non-GAAP operating margin 30% to 31%.; Q3 diluted net income per share $2.15 to $2.35.
Revenue $808.4M; EPS $1.5
Management’s revenue guidance appears to have been met or slightly exceeded, but EPS values in the provided dataset complicate a clean non-GAAP comparison.
Topics investors and analysts likely monitored as management’s ramps and constraints evolved through FY2026.
Under-shipment can cap revenue even when demand is strong, affecting margin and guidance credibility.

Commentary on 1.6T module uptake timing, yields/scrap improvements, and supply-limited shipments vs demand.
Supply constraints and pricing
Management repeatedly described shipping behind customer demand—initially framing a growing EML-specific gap, then expanding commentary to transceivers and high-powered laser supply in later quarters. To manage the imbalance, they consolidated customers via LTAs, used targeted price increases, and kept margins supported through mix and utilization gains.
OCS ramp execution
OCS showed a clear narrative arc: management referenced early ramp progress and timing in Q2, reiterated backlog momentum across multiple customers in Q2, and later highlighted supply-chain gating and “tight rope” constraints in Q3. By Q4, they guided to the first triple-digit OCS revenue quarter and confirmed $400M+ planning for the second half of calendar 2026.
CPO and emerging architectures
Throughout the year-end discussion, management reframed CPO and adjacent opportunities: Q4 emphasized demand ramp confidence for ultra-high-power laser chips, plus momentum in near-packaged (NPO) and an initial external light source (ELS) module purchase. Earlier quarters discussed initial inflections and confidence-building engagement, culminating in sharper timing language for scale-up deployments.

Management described transceiver execution turning a corner in Q1 and improving profitability via yields and lower scrap rates in Q2. By Q4, they began shipping 1.6T modules as planned, with improving visibility into uptake.
OCS moved from early ramp discussion to backlog strength and eventually a triple-digit quarterly revenue expectation. Even with supply-chain tightness in Q3, management described execution as on plan by Q4.
Management described EML supply-demand gaps widening in Q1 and staying around 25–30% in Q2. In Q3, imbalance was described as greater than 30%, and in Q4 high-powered lasers were the lagging vector.
In Q3, management called out constraints on critical components for shipments and described pump laser constraints as “unanticipated” and requiring allocation decisions. Q4 reinforced continued lag in high-powered lasers amid demand acceleration.
Management flagged that software complexity for OCS kept them up at night in Q1 and that OCS pace was gated by supply chain tightness in Q3. By Q4 they still referenced tighter visibility and execution focus.
Management invested in CapEx each quarter to support cloud and AI ramps, while free cash flow was negative in Q1 but improved later. They also described capital and ramp pressures tied to capacity planning and LTAs.
