A：EML is positioned to capitalize on future market opportunities through capacity expansions across its two Indian phospho wafer fabs in Japan, with plans to qualify both CW and EML process flows on new tools as they come online. Additional capacity is being allocated to CW lasers to meet demand. EML expects revenue growth in the second half of 2026 and into 2027 to capture opportunities from 200 gig and 300 gig lane speeds. The company's ability to deliver at scale and meet tight specifications is seen as a distinctive competitive advantage, which is expected to contribute to its growth targets.

A：Systems product category revenue reached $357 million, marking a 30% sequential and 123% year-over-year increase, primarily driven by cloud transceivers and OCS. Cloud transceivers experienced a 30% sequential increase and shipped at 800 gig speeds, with some units at 1.6 T speeds. OCS revenues grew over 100% sequentially, and the company expects the first triple-digit OCS revenue quarter. EML anticipates a stronger demand for 2027 with continued growth in AI and OCS applications. The company's roadmap includes higher and lower count products, and it plans to set a quarterly record in Q1, reaching a $1.25 billion revenue target ahead of schedule. This growth is expected to come from both components and systems portfolios, driven by the ongoing ramp of 1.6 T transceivers and accelerated OCS deliveries.

A：In the fourth quarter, EML proactively converted a portion of its convertible notes following stock appreciation, which reduced its debt by $1.1 billion, or approximately 35% of outstanding convertible notes. This action resulted in a one-time non-cash charge of $7.8 billion, leading to a GAAP net loss of $7.2 billion for the quarter. Despite this, non-GAAP financial measures showed gross margin and operating margin improvements, with non-GAAP net income and per-share income at $326.3 million and $3.23, respectively.

A：EML is continuing to invest in critical research and development (R&D) programs catering to cloud and AI customers while maintaining rigorous cost controls to optimize its business model. Fourth quarter non-GAAP operating profit was $368.8 million, and adjusted EBITDA was $406.4 million. Non-GAAP operating expenses were $138.1 million, and R&D expenses were $87.5 million. These figures reflect the company's commitment to managing expenses in line with revenue growth and pursuing its strategic initiatives.

A：EML's guidance for the first quarter of fiscal year 27, based on current assumptions, anticipates net revenue in the range of $1.225 billion to $1.275 billion, reflecting more than 130% year-over-year growth and setting a new all-time quarterly revenue record. Non-GAAP operating margin is expected to be in the range of 39.5% to 40.5%, and diluted net income per share is projected to be in the range of $4.50 to $4.35. This operating margin represents an expansion of more than 2100 basis points year over year. EML's non-GAAP EPS guidance is based on a non-progressive tax rate of 16.5% and assumes approximately 102 million diluted shares used for non-GAAP diluted earnings per share.

A：The company expects to achieve its first triple-digit OCS revenue quarter in the first quarter, which is implied to be the current quarter mentioned by the speaker. For ultra-high powered lasers, the expectation is to reach a triple-digit quarter in the third quarter.

A：The capacity expansion plans for Greensboro are progressing well. The team has taken the lead in converting the facility from Gallium Arsenide to Indium Phosphide, and they are ahead of schedule. The expectation is to generate revenue from the new capacity in early 2028, ramping through calendar 2028, and into full production by the end of 2028 and into 2029.

A：The OCS revenue tracking for the second half of 2026 is not ahead of the 400 million plus guidance but is executing as planned, with some difficulties early on in the supply chain which have since been resolved. The company is on track with expectations for the year. One customer has an internal source of supply, but as they ship more OCS products, they are expected to absorb the vast majority of it. Michael predicts that in early 2027, the company will cross over to become the number one supplier and maintain momentum in OCS shipments thereafter.

A：The supply and demand balance has not significantly changed on EML, with the company still shipping behind customer demand. However, it hasn't worsened either. The major change since the last discussion is in high-powered lasers, where the company is very much behind schedule due to increased demand signals. The company is working on improving this situation.

A：The company has fallen further behind on high-powered laser shipments due to an acceleration in demand signals. Despite executing well on the ramp, high-powered lasers are the area where the company is most behind schedule, with demand increasing and the company struggling to keep up with supply.

A：The company has received its first order for an EML module, which has a significantly higher ASP than the set of lasers. The module is expected to be shipped sometime in the mid-year, early second half of 2027. Although the margins are not as good as lasers, they are higher than the corporate average. The company is excited about the revenue opportunity from EML modules, especially as it scales out. Initial participation in the early phases of scale up is anticipated to be both with lasers and EML modules.

A：The purpose of shipping the EOS to one customer is to enable that customer who is not familiar with handling individual laser chips to utilize the EOS for their CPO and MPO systems. This first step will then enable other end-users to use the EOS to support their systems as well.

A：The current status of 1.6 cycle or 200 gig per lane transceivers is that they are becoming a larger part of the supply chain and are anticipated to be a significant portion of transceiver shipments. This is an acceleration from earlier predictions where the involvement of CW lasers was expected to increase and become more prevalent as 3.2 T silicon photonics loses some of its advantages.

A：The impact of reducing the die size of the CW lasers is that it has improved their performance and allowed them to command a significant price premium, thereby closing the margin gap with EML lasers. Although EMLs still offer better margins, the gap has narrowed considerably since the last time the comparison was discussed.

A：The updated forecast indicates that 200 gig per lane EMLs are expected to be the majority volume shipments by mid-2027, with a mix of 25% at the moment, anticipated to rise to 50% or more by mid-year 2027. The forecast for the crossover in terms of revenue and profitability remains consistent with previous expectations, with no significant change reported.

A：As the company approaches $2 billion in revenue, the operating leverage is expected to improve, with a guidance given of 38% to 42% at that revenue level. At much lower revenue levels, the company is already at the midpoint of that range. With improving gross margins, this is expected to lead to an improvement in the operating margin line.

A：The surge in demand for the company's products was unexpected and significant, leading the company to find additional substrate help from AXT to cope with the increased demand.

A：The company is looking for more help on substrate and considering new arrangements to utilize more of the capacity at their Greensboro location. They are in talks with customers about helping them with their laser demands, as the demand is changing rapidly and they may need to adapt quickly.

A：Yes, the company is looking to sign long-term agreements for more capacity in Greensboro. They have reported consistently that they have capacity in Greensboro and have been discussing with customers how they can assist with their changing laser demands.

A：The intersection of NPO and ASIC or NPU roadmaps does not seem to be achievable with existing GPUs or XPU as the required S speed is not fast enough. However, with new generations of silicon expected to come online in mid-2027, these will likely support the adoption of NPO or CPO solutions.

A：There is no significant evidence of NPO being retroactively implemented onto current xpu systems. The momentum is towards the adoption of MPO and CPO solutions, which are driven by optical scaling and are not just about the xpu itself, but also involve a broader system architecture that requires optical scaling.

A：The competitive dynamic for OCS is similar to MPO in that it is additive to the current Total Addressable Market (TAM). OCS is not imminent but is becoming increasingly important, requiring significant redesign by the company's engineers. OCS is not a near-term event but is expected to intersect with the market in the future.

A：The long-term agreements for scaling up the business are primarily three-year arrangements with pricing built-in. These agreements allow for pricing levers to be exercised under certain conditions, providing price certainty and ensuring demand for the company's products.

A：The company has very large market share in pump lasers, with rough order between 70-80% share. They have a strong technology roadmap that they believe their customers will engage with, which will allow for further price adjustments and output increases.

A：The company's discussions and engagements are related to very specific types of NPO implementation driven by their customers, which will constitute the first wave of NPO engagement.
