On August 12, 2026, Coherent Corp. (NYSE:COHR) beat fourth-quarter earnings estimates and forecast first-quarter revenue and profit above expectations. Yet, its shares slipped 4% in extended trading. Lumentum Holdings Inc. (NASDAQ:LITE), a rival optical component maker, reported its results a day earlier, on August 11, 2026, with revenue guidance that CEO Michael Hurlston said would hit the company's long-term target model a full quarter ahead of schedule. Why This Matters Both companies make the optical components that move data inside AI data centers, and both are seeing real demand from the same hyperscaler buildout. That raises the real question: if the demand story is this strong for both, why did the market reward one stock and sell the other? The Bull and Bear Case: Coherent Coherent Corp. (NYSE:COHR)'s data center and communications segment, its largest, generated $1.62 billion in revenue, up from $1.02 billion a year earlier. Overall quarterly revenue of $2.05 billion beat the $1.99 billion analysts expected. CEO Jim Anderson said the company enters fiscal 2027 "with exceptional customer demand, expanding production capacity." Coherent forecasts first-quarter revenue of $2.2 billion to $2.4 billion, above the $2.14 billion analysts modeled. Nvidia itself invested $2 billion in Coherent in March 2026 to support research, manufacturing, and operations. However, revenue in Coherent Corp. (NYSE:COHR)'s industrial business segment fell 16% during the quarter. The company reported sharply lower full-year operating cash flow. Shares had already climbed nearly 93% for the year heading into the report, leaving little room for anything short of a clean beat, and the stock fell anyway despite one. The Bull and Bear Case: Lumentum Lumentum Holdings Inc. (NASDAQ:LITE)'s press release said the company's trajectory "continues to accelerate as AI demand drives" its first-quarter revenue guidance midpoint to $1.25 billion, reaching its target model a quarter ahead of schedule. Non-GAAP net income for the fourth quarter came in at $326.3 million, or $3.23 per diluted share, up sharply from $63.3 million a year earlier, and the company guided first-quarter non-GAAP earnings per share of $4.05 to $4.35. Lumentum Holdings Inc. (NASDAQ:LITE) reported a GAAP net loss of $7.2 billion for the quarter, driven almost entirely by a one-time $7.8 billion non-cash loss tied to converting some of its convertible notes into equity, a reminder that the company's balance sheet still carries complexity investors need to look past to see the underlying business. Insider Monkey's Hedge Fund Data Coherent Corp. (NYSE:COHR) was held by 114 hedge funds as of Q1 2026, up from 109. Lumentum Holdings Inc. (NASDAQ:LITE) was held by 123 hedge funds, up from 97. Conclusion Coherent and Lumentum are both genuinely benefiting from the same AI optics boom, but Coherent's post-earnings drop shows how little room for error even a strong quarter leaves once a stock has already run this far. While we acknowledge the potential of COHR as an investment, we believe certain AI stocks offer greater upside potential and carry less downside risk.

The Dow Jones Industrial Average (DJINDICES:^DJI) fell 1.32% to 52,759, the S&P 500 (SNPINDEX:^GSPC) declined 0.85% to 7,642, and the Nasdaq Composite (NASDAQINDEX:^IXIC) dropped 1.00% to 26,067 as rising oil prices and retail earnings pressure snapped Wednesday's relief rally. Retail giant Walmart (NASDAQ: WMT) weighed on the market following a profit report that dampened consumer sentiment, while TJX Companies (NYSE:TJX) fell roughly 3% after reporting a rare miss in its largest business segment. Robinhood Markets (NASDAQ:HOOD) reversed its earlier gains to close lower despite positive sentiment from a White House crypto summit, while Lumentum Holdings (NASDAQ:LITE) shares rose as leadership highlighted surging demand for AI infrastructure components. Walmart shares helped lead the market lower after it reported earnings, with its stock sliding 9%. WMT stock is in the Dow, S&P 500, and Nasdaq-100, so its slide weighed heavily on the broader market today. That said, the company beat analysts' expectations, but same-store sales of 2.6% and its 2026 guidance were weaker than hoped. Furthermore, management noted that $4 gas prices seem to be having a psychological effect on consumers' spending habits. Meanwhile, apparel retailer TJX offered guidance that surpassed Wall Street's expectations -- and the company beat sales and earnings expectations for the quarter -- but the stock retreated 3% anyways. With the U.S. national debt passing $40 trillion yesterday, relations with Iran still tumultuous at best, and bond yields still rising despite the Treasury's plan for a bond buyback, the market has become a bit more iffy than it has been recently. That said, two-thirds of the stocks in the S&P 500 are positive so far in 2026, so it is important to zoom out a bit and realize we are not in a perilous situation just yet.

Fabrinet crashed 20% on decelerating Q1 guidance after running up 25% pre-earnings, dragging Marvell down 8% and Amphenol 7%. Coherent fell 12% and Lumentum dropped 10% despite posting datacenter revenue growth of 59% and 109% last quarter. Anthropic's $65 billion ARR missing $80 billion expectations and the 30-year Treasury hitting a 19-year high amplified selling across AI hardware. Act now: the analyst who called NVIDIA in 2010 just named his top 10 AI stocks — and Marvell Technology didn't make the cut. Grab the names FREE today. Shares of Fabrinet (NYSE:FN) are down roughly 20% at midday Tuesday, trading near $476 after the optical manufacturer posted a fiscal Q4 beat but disappointed a market already primed to sell AI infrastructure names. The move is dragging the whole optical and connectivity complex lower. Marvell Technology (NASDAQ:MRVL) is off nearly 8%, Amphenol (NYSE:APH) is down about 7%, Coherent (NYSE:COHR) is off about 12%, Lumentum (NASDAQ:LITE) has dropped roughly 10%, and Corning is down nearly 8%. After Monday's close, Fabrinet reported record Q4 revenue of $1.316 billion, up 45% year over year and above guidance. Non-GAAP EPS came in at $4.10 versus $2.65, an all-time high. Full-year revenue reached $4.64 billion, up 36%. CEO Seamus Grady called the quarter "exceptional, capping off a remarkable year of accelerating growth and strong momentum." View the 8-K filing here. The problem is positioning. FN ran up roughly 14% in the week and 25% in the month heading into the earnings report, and Q1 guidance of $1.375 billion to $1.425 billion implies a far more modest sequential step-up than the 45% YoY quarter just delivered. Add a disclosed $56.7 million loss on non-marketable equity securities and heavy capex that pushed Q4 free cash flow to negative $36.9 million, and a beat-and-raise turned into a "good but decelerating" setup. This is Fabrinet's largest earnings-day drop in the last six quarters, roughly 2.2x the typical post-earnings selloff. Act now: the analyst who called NVIDIA in 2010 just named his top 10 AI stocks — and Marvell Technology didn't make the cut. Grab the names FREE today. Fabrinet lit the fuse. Macro caught it. Over the weekend, Anthropic told investors ARR hit $65 billion at the end of July, huge growth but below the $80 billion-plus figures Gavin Baker had cited on The All In Podcast. Reuters then reported Anthropic's own 2028 revenue estimate of $190 billion to $200 billion, again below what some investors were modeling. The Wall Street Journal capped it, reporting that nine top tech companies carry roughly $3 trillion of off-balance-sheet commitments mostly related to AI, growing faster than traditional capex. The 30-Year Treasury hit a 19-year high today, and with the 10-year yield at 4.7%, near a 12-month high, long-duration AI hardware names are the natural fade. The Marvell and Amphenol declines reflect more than one contract manufacturer's guidance. Marvell just guided Q2 to $2.7 billion, implying 35% YoY growth, with CEO Matt Murphy citing "exceptional AI-related bookings." Coherent's fiscal Q4 datacenter revenue was up 59% YoY. Lumentum's Q4 revenue grew 109%. This is a positioning and sentiment reset landing on a red-hot cohort of optics, connectivity, and infrastructure suppliers behind the AI buildout (we profiled seven of these picks-and-shovels names, from power to cooling to networking, in a free report here: 7 Stocks Powering the AI Boom). Lumentum is still up roughly 736% over the past year, and Coherent 276%. Elevated expectations were the fuel; today they are the risk. Watch whether analyst targets Fabrinet, currently at a consensus $732, get trimmed into the close. NVIDIA reports next week, and its data center commentary will decide whether today is a shakeout or the start of something larger.

Lumentum's press release with the fiscal fourth quarter and full year 2026 results and accompanying supplemental slides are available on our website at investor.lumentum.com. We encourage you to review these materials carefully. With that, I'll turn the call over to Michael. Michael E. Hurlston: Thank you, Kathy, and good afternoon, everyone. Lumentum is positioned at the heart of a secular industry shift. As AI compute workloads increased in both speed and bandwidth, data center architects are turning to optical links as a primary means of connectivity. Our fourth quarter results reflect the early stages of this transition, driven by broad-based momentum across our scale-out and sell across product lines. Revenue surged 109% year-over-year to $1.01 billion, marking our eighth consecutive quarter of top line growth. Additionally, we are maintaining revenue velocity as we saw our third consecutive quarter of greater than 20% sequential growth notable as the compare point is getting ever larger. While we experienced broad-based success, some of our previously highlighted growth drivers are just starting to layer in. Notably, in cloud transceivers, we achieved record 800 gig shipments, while initiating production of our next-generation 1.6T modules. In OCS, we successfully navigated supply chain constraints to meet steep customer demand, ramping internal manufacturing shipments according to plan. In addition to strong top line performance, non-GAAP gross margin crossed 50%. We had originally targeted this threshold at a $2 billion quarterly run rate. So this milestone came quite a bit sooner than expectations. We expect gross margin expansion to continue driven by product mix and tight operational execution. Non-GAAP operating margins expanded by more than 2,150 basis points year-over-year. These results prove 2 things: Our differentiated technology commands premium value and our operating model delivers outsized leverage. Driven by sharp acceleration in AI revenue, the midpoint of our Q1 revenue guidance reaches our $1.25 billion target more than 1 quarter ahead of schedule. Additionally, our Q1 non-GAAP operating margin guidance exceeds the high end of our target model that we associated with this revenue level. I'd like to address some recent market noise around co-packaged and near-packaged optics. First, our lead CPO customers' production plans remain very much on track and their demand signal has increased since our last update. Our visibility into the timing of CPO scale-up deployments is also sharpened. We remain confident in a demand ramp for our ultra high-power laser chips in the second half of calendar 2027 ahead of customer scale up deployments in calendar 2028. Because the first phase of scale-up optical connections will span across compute racks within the cluster, this demand ramp applies to any topology larger than one rack. Adding to our confidence, we have recently given our first external line source or ELS module purchase for delivery by the second half of calendar 2027. Second, the rest of our customer base is currently prioritizing near-packaged architectures as an intermediate step to the eventual adoption of CPO. The NPO opportunity is completely additive for us, significantly increasing optical TAM. We're seeing strong NPO momentum across multiple high-velocity engagements using our differentiated laser chips. Even our largest CPO customer is looking at NPO for specific new use cases further increasing the optical TAM at that account. These architectural shifts represent a major market inflection that plays directly to our core strengths as a premier laser chip manufacturer, benefiting us as optics begin to penetrate the copper domain. NPO offers a faster time-to-market option by placing optical engines on the board right next to the XPO accelerator, training power and costs for simplicity and optical scale-up applications. Customers are evaluating 2 types of laser chips for NPO. In mid-power laser integrated directly with the optical engine and a high-power laser used in an external light source module. Our mid-power lasers inherent the reliability and engineering of our flagship high-power platform. Our family of NPO and CPO lasers utilizes common design and process know-how to achieve industry-leading efficiency across 120 milliwatt, 150-milliwatt and 400-milliwatt output levels. Looking ahead, CPO continues to be viewed as the natural end state on the technology road map, placing optics directly on the substrate or interposer for maximum power efficiency through foundry-level advanced packaging. Now let's look closer at the metrics to define our fourth quarter, starting with the components product category. Components revenue for the fourth quarter was $649 million, reflecting 22% sequential and 103% year-over-year growth increases. Our laser portfolio continues to demonstrate strong momentum across every vector. Shipments of our narrow linewidth laser assemblies grew sequentially for the tenth consecutive quarter, and we were up over 130% year-over-year. Pump laser shipments surged more than 80% year-over-year, and we will remain effectively sold out for the foreseeable future despite our rapid capacity expansion. Expanding, inferencing and training applications are driving full rate connectivity between data centers, while political and regulatory constraints favor smaller, more modular builds. These 2 factors among others are substantially increasing the demand for our pump laser solutions. To put this in perspective, for one major hyperscaler, the network capacity connecting just 2 AI data center sites could double the total global backbone capacity they built over the entirety of the last decade. To support the growth and scale across deployments, we have secured multiple long-term customer agreements that helped offset our planned capital expenditures. We continue to expect a fourfold increase in our pump laser shipments over the next several quarters to meet this escalating demand. Turning to laser chips. We delivered another record-breaking quarter for EMLs, primarily driven by strong demand for 100-gig per lane devices. Momentum for our 200-gig EMLs is also accelerating rapidly, now accounting for over 25% of total EML revenue. Simultaneously, we are expanding our laser chip strategy to capture broader market opportunities in ways that aligned with our financial model. A key example is our CW laser chip for 200 gig per lane applications, which delivers high yield, proven reliability and industry-leading performance in a compact form factor to a multitude of customers. Internal deployment of these lasers reinforces what our customers regularly confirm. We have a distinctive ability to deliver at scale to a very tight set of specifications, which enables superior yields in transceiver manufacturing. Importantly, these new CW laser products will deliver margins that are accretive to our long-term financial targets. Looking ahead, we expect demand for both EML and CW lasers to grow significantly through the second half of calendar '26 and into 2027. To capture the coming 200-gig and 300-gig lane speed opportunities, we are expanding capacity across our 2 indium phosphide wafer fabs in Japan, qualifying both CW and EML process flows on our newest tools as they come online. Even as we allocate additional capacity to CW lasers, we remain on track to deliver over 50% EML unit growth by December 2026 quarter compared to the year ago quarter. Wrapping up our components commentary, we have visibility to an expanding set of 3D sensing applications. These new opportunities are expected to drive growth in upcoming product cycles with our primary customer. Now I will move to our systems product category. Systems fourth quarter revenue reached $357 million, representing a 30% sequential and 123% year-over-year increase. Both cloud transceivers and OCS were major drivers of the revenue growth quarter-over-quarter. While pockets of supply chain tightness for certain components capped shipments below total market demand, our factories executed to our aggressive plan for both product lines. The bulk of our cloud transceiver shipments in the quarter were at 800 gig speeds, and we began shipping 1.6T transceivers as planned. Meanwhile, profitability across our transceiver lines continues to improve, driven by gains in both yield and capacity utilization as well as the initial rollout of higher ASP 1.6T transceivers. Our visibility into future cloud transceiver demand is clearer than ever. In fact, we expect the 1.6T transceiver uptake to intensify starting in fiscal Q1 and sustain through calendar 2027. This momentum is anchored by our lead Tier 1 hyperscale customers whose strong rollouts of custom AI clusters are driving a rapid transition from 800 gig to 1.6T technology. Through the use of improved design engineering techniques, we appear to be first to market in many instances ahead of larger competitors, giving us a market share advantage that we should be able to maintain through the cycle. The degree of difficulty with 1.6T designs, again, is playing to our strengths as our Signal Integrity team is widely acknowledged as the best in a competitive field. Turning to OCS. Our internal manufacturing expansion is progressing smoothly. After doubling shipments from fiscal Q3 to Q4, our guidance includes our first triple-digit OCS revenue quarter. The demand signal for 2027 continues to be incredibly strong, and we have started the initial work to add capacity with contract manufacturers as well as continuing to increase output in our internal factories. Since our last call, the road map for OCS has also come into better view. We are now planning higher and lower port count products, including specialized in-tray offerings. Rounding out our systems category performance in industrial lasers and cable access strengthened quarter-over-quarter. Within industrial lasers, we are seeing increased adoption of our ultrafast lasers targeting high-density PCB via drilling that supports advanced AI XPU boards and 1.6T optical modules. Looking ahead to Q1. We expect to set another quarterly record and as stated earlier, reach our $1.25 billion revenue target more than one quarter ahead of the plan outlined at the last OFC. We anticipate that approximately half of the sequential growth will stem for our components portfolio driven by continued expansion in scale-out and scale-across applications. The other half will be powered by the ongoing ramp of our systems portfolio of about 1.6T transceivers and accelerating OCS deliveries. Now I'll hand the call over to Wajid. Mr. Ali? Wajid Ali: Thank you, Michael. Fourth quarter revenue of $1.01 billion was at the high end of our guidance range and non-GAAP EPS of $3.23 was well above our prior expected range, demonstrating the leverage of our business model. GAAP gross margin for the fourth quarter was 47.4% and GAAP operating margin was 27.8%. Both metrics exemplify the company's exceptional performance. As disclosed previously, in the fourth quarter, we proactively equitized a portion of our convertible notes, which were in the money following the appreciation of our stock over the past year. This action reduces our debt by $1.1 billion or approximately 35% of our outstanding convertible debt. This transaction resulted in a one-time non-cash GAAP charge of $7.8 billion, bringing our fourth quarter GAAP net loss to $7.2 billion. Turning to our non-GAAP results. Fourth quarter gross margin was 50.4%, which was up 250 basis points sequentially and up 1,260 basis points year-on-year due to better manufacturing utilization, favorable mix and increased pricing on select products. Fourth quarter non-GAAP operating margin was 36.6%, which was up 440 basis points sequentially and up 2,160 basis points year-on-year. We continue to invest in critical R&D programs serving cloud and AI customers while maintaining the rigorous cost controls necessary to optimize our business model. Fourth quarter non-GAAP operating profit was $368.8 million and adjusted EBITDA was $406.4 million. Fourth quarter non-GAAP operating expenses totaled $138.1 million or 13.7% revenue, an increase of $11.9 million from the third quarter and an increase of $28.8 million from the same quarter last year in support of expanding cloud and AI opportunities. Q4 non-GAAP SG&A expenses were $50.6 million. Non-GAAP R&D expenses were $87.5 million. Total interest and other income net was $22 million on a non-GAAP basis. Fourth quarter non-GAAP net income was $326.3 million and non-GAAP net income per share was $3.23. Our diluted weighted shares for the fourth quarter were 101.1 million on a non-GAAP basis. I will now turn to the balance sheet. During the fourth quarter, our cash and short-term investments decreased by $0.43 billion to $2.74 billion, with the decrease primarily driven by convertible debt conversions. Our inventory levels increased by $59 million sequentially to support the expected growth in our cloud and AI related revenue. In Q4, we spent $167 million in CapEx, primarily focused on manufacturing capacity to support cloud and AI customers. Turning to revenue details. Components revenue of $649.4 million increased 22% sequentially in Q4 and 103% year-on-year. Systems revenue of $356.9 million increased 30% sequentially in Q4 and 123% year-on-year. Now let me move to our guidance for the first quarter of fiscal year '27, which is on a non-GAAP basis and is based on our assumptions as of today. We anticipate net revenue for the first quarter of fiscal year '27 to be in the range of $1.225 billion to $1.275 billion. The $1.25 billion midpoint reflects more than 130% year-over-year growth, setting yet another all-time quarterly revenue record for Lumentum. We project first quarter non-GAAP operating margin to be in the range of 39.5% to 40.5% and diluted net income per share to be in the range of $4.05 to $4.35. At the midpoint, this operating margin represents an expansion of more than 2,100 basis points year-over-year. Our non-GAAP EPS guidance is based on a non-GAAP and annual effective tax rate of 16.5%. These projections assume shares used for non-GAAP diluted earnings of approximately 102 million. With that, I'll turn the call back to Kathy to start the Q&A session. Kathy? Kathryn Ta: Thank you, Wajid. [Operator Instructions] Operator: [Operator Instructions] Your first question comes from the line of Joseph Cardoso with JPMorgan. Joseph Cardoso: Maybe for the first one, obviously, you highlighted you're tracking to hit the $1.25 billion revenue target a quarter early and are already running well ahead of your high end of margin targets here. Just given both the stronger demand and maybe the more favorable mix, how should we be thinking about the read-through to the next set of financial targets, particularly given what looks like incremental opportunities forming relative to the framework, including ELS, NPO engagements. And I think you even mentioned scale up OCS as well. Just curious in terms of how we should be thinking about the next set at this here? Michael E. Hurlston: Joe, this is Michael. Firstly, thanks for your continued support. Look, we'll come out with some new financial targets, probably at the next OFC. We're obviously running well ahead on almost every metric on revenue, on margin, on operating margin. We seem to be doing quite a bit better. And you're right. Look, I think there are some new things that we didn't factor into our discussion at OFS. NPO, we spent a bit of time on the -- in the prepared remarks on NPO. CW lasers, we think that's an incremental opportunity for us that we would probably not spend a lot of time on before. And you're right, OCS, I think, as we've discussed, but it seems to be doing a bit better than expected. So we feel like we're executing. We're trying to keep our head down and run and obviously adding nearly $250 million incrementally into the guide is pretty impressive, and we think we have the opportunity to do that more as we look out in future quarters. Joseph Cardoso: Got it. Fair. And then maybe just a follow-up and specifically on the NPO. Curious if you could provide any further details there, specifically how you're thinking about the time here, just given that it does sound like some of these opportunities are forming a little bit earlier than expected. And I know you talked about the different form factors or the different kind of content opportunities as it relates to the laser opportunities there. But any way to kind of flesh out like where you guys are seeing maybe the architecture of choice by your customers and is that biased in any direction? And how we should think about content as it at least relates to maybe your large customer on the CPO side relative to the ultra high power laser. Michael E. Hurlston: Yes. I'm going to say a couple of things and then actually ask Wupen to comment a little bit on the differentiation in mid-power. Certainly, the timing of these opportunities is plus or minus what we have talked about for our lead CPO customer. Our lead CPO customer, we just said in the prepared remarks, we would expect to start shipping in high volume for scale-up. We're already, of course, shipping for scale-out. For scale-up, we expect to be shipping in the second half of calendar '27 for their deliveries in '28. Our leading customers on NPO, plus or minus, probably maybe minus a quarter, are in that ZIP code. The first couple of those are more -- is the same kind of ELS high-powered laser and then maybe followed by a couple that are integrated where the optical engine of a mid-power laser is integrated inside the optical engine, and it's all one unit. So I would say that the ones that we have the best line of sight on and that are sooner are more of the high-powered laser type, very consistent with what we've been talking about for our largest CPO customer. With that said, I wanted Wupen, maybe to give a few seconds of color because I think there's a little bit of a mischaracterization. We think that these mid-power lasers that are going inside the OE, lot of things going on there in terms of differentiation. Do you want to give 2 seconds on that? Wupen Yuen: Yes, definitely. Thanks, Michael. So definitely, the -- it is the -- to do the kind of the NPO optical engine, imagine these NPOs set at about 6.4T of bandwidth, which is really equivalent to 4x that of a local CC module. The level of integration and the power density that's required and efficiency required to fit everything to a small optical engine is immense. Therefore, you need really the best laser technology and the best efficiencies in order to really fit everything in a small package. So Lumentum's advantage here really is to leverage our 400-milliwatt kind of design principle and leverage the high efficiencies of the intrinsic design process and scale it to an application, right, around 150, 200-milliwatt range, that enables that application. This is actually based on our ultra-high power technology that we uniquely positioned to address this market, and we believe that by late 2027-2028 timeframe, that NPO will hit the market to enable optical scale-up, and this becomes an interesting opportunity for us to increase our laser business. Operator: Your next question comes from the line of Simon Leopold with Raymond James. Simon Leopold: First thing I wanted to try to ask is, to what extent we're able to reprice backlog with your customers? And how did that affect this quarter's gross margin as well as your gross margin outlook? And then I've got a quick follow-up. Michael E. Hurlston: Yes. Thanks, Simon. Look, we did reprice a little bit. I think most of our sort of LTAs are more forward-looking in terms of the price impact. We saw some benefit, as Wajid said in his prepared remarks, on the gross margin line on pricing. We think that, that still has some room to play through. But I'd say the long pole this quarter was more on mix, right, where we were shipping a lot more of our high mix components and I think as we said, we'd expect that to continue to play through as well. So we think we have some room to run on gross margin line side. Simon Leopold: Great. Appreciate that. And the other thing I've been hoping to ask you about is we've been hearing more about Chinese-based companies coming to market with new indium phosphide fabs. What's your take on this developing and future competition? Michael E. Hurlston: Yes. Look, I mean, I think we're hearing the same thing. We obviously haven't seen any impact on our numbers as yet, and I don't expect there to be any impact. We think we have differentiation, obviously, on EMLs. We were very strong there. And these high and mid power lasers that are necessary for NPO and CPO, again, very strong differentiation there. And then even in CW, we've been surprised at our ability to price up given what we said in the prepared remarks that customers are seeing far better yields given our ability to deliver consistent performance on our lasers. They just simply don't deviate. The width of the spec is very narrow, and that results in far better transceiver yields for the customers that we've actually started shipping CW lasers to. And so as a result, we are able to command a nice price premium that we'd expect to sustain as these Chinese -- if these Chinese guys come online. I caution people also -- I think people are -- some of these Chinese laser suppliers are not delivering in the market today. So they have very -- there's no recourse when they throw out these big numbers. We have not seen anything like that to date in terms of their output. Operator: Your next question comes from the line of Mike Genovese with Rosenblatt Securities. Michael Genovese: Really good to see the guide for a triple-digit OCS revenue quarter, I think, in the current quarter, I think is what you said. So could you just confirm that? But also the question is, any comment on when we could expect to see that happen for ultra high-powered CW scale-out lasers where we'd get triple-digit quarter? Michael E. Hurlston: Yes, Mike, again, first, I want to thank you for the support of the company and really following our details really well. Yes, you've got it right. So in the guide, which is the first quarter, we expect our first triple-digit OCS revenue quarter, we'd expect to be meaningfully above the 3-digit mark. We're executing well on OCS, as I said. And then for ultra-power lasers, we have said, hey, we expect by the end of the year to be sort of in the $50 million mark. I think the third quarter is when you'd see the first triple digit quarter for ultra-high powered lasers. So we are executing. We're shipping today. We had a good shipments in this -- in the reported quarter, Q4. We'd expect that to build somewhere in the $50 million range by the end of the calendar year, and then to really meaningful impact in fiscal Q3. Michael Genovese: Great. Perfect. And then finally, for Greensboro. Just any -- is there any update on the expectation for sort of half of the capacity of Greensboro being there in calendar '28, the other half in calendar '29? Is that still the schedule? And I know it's early, but any kind of color you could give us on the progress there would be great. Michael E. Hurlston: Yes. Look, progressing super well. I'm actually very pleased that the team that we got in Greensboro is first rate. As you know, we inherited a fully functioning fab. So the switch that we need to throw is to convert it from gallium arsenide indium phosphide. That is well underway. Some of the long haul items, reactors and things like that, our team has gotten out in front of. I think we continue to say revenue -- first revenue out of that in early 2028 and ramping through calendar 2028 into kind of a full pitch by the end of '28 and into '29. So really no change in that, Mike. Operator: Your next question comes from the line of Papa Sylla with Citi. Papa Sylla: Congrats on the strong results as well. Michael, I was kind of double clicking on the OCS. I was hoping perhaps you can refresh us. I know this quarter, you mentioned it hit triple digits, but if you can refresh us on the $400 million plus OCS guide for the second half of 2026. Are you running well ahead of it or just any update on that side? And perhaps tied to that, how should we think about your key OCS customers build versus buying from you calculus? Do you expect Lumentum to eventually absorb most of their internal programs? If so, any timeline in mind? Michael E. Hurlston: Yes, Papa, look, what I'd say is we're definitely tracking to the $400 million. I would not say tracking ahead. I mean, we definitely, as you know, had some problems early on in the ramp with supply chain. We're out of that now. I think we're executing, as I said, to plan. We are plus or minus about where I would have expected to be for the guide, right? So that contributes -- takes a dent out of the $400 million and that leaves us some room to run in the fourth quarter -- fourth calendar quarter. Relative to one customer that apparently has an internal source of supply, we are, I think, executing extremely well. I don't think we -- I think they'll continue to use an internal version. But I think as they ship more and more OCSs, we will absorb the vast majority of that. So I would expect sometime in early '27 that we cross over and be the #1 supplier and actually have momentum from there in terms of our OCS shipments. So we definitely, I think we surprised the customers. We are continuing to ship to a number of different customers. Our execution back on track, but most importantly, like on software and things like that, where I had expected us to have more difficulty, Papa, we've done well. So I think our customers, in general, if you talk to them, would say, we've been an incredibly, incredibly strong supplier. Papa Sylla: No, that's great to hear. And Michael, for my follow-up, just curious on the -- any update on the supply/demand kind of imbalance? I believe last quarter you mentioned 30% plus. Where are we now? And how do you see that improving? Or how do you see that going into fiscal '27 and beyond? Michael E. Hurlston: Yes. So I would say on EML, probably no change, right? So I don't think that it's gone up, but it hasn't come down. We're still shipping behind customer demand on EML. I think what surprised us is high-powered lasers, right? High-powered lasers, again, there's been a lot of noise in the system on what's happening on various co-packaged and near-packaged opportunities. We are way behind. Our shipments, unfortunately, on high-powered lasers. So we -- if one vector has really changed since the last time you and I talked, I'd say it's your high-powered lasers, and we are very much further behind. The demand signals increased and we are very much further behind relative to our ability to supply. Wupen Yuen: Yes. I think just to clarify -- yes, just to clarify, our execution of the ramp is on track, right? We're further behind because our -- the demand has accelerated. That, as Michael said in the prepared script. Operator: Your next question comes from the line of Christopher Rolland with Susquehanna. Christopher Rolland: My question, in your press release, it sounds like you were selling not just ELS lasers, perhaps ELS modules as well. And I was wondering if you could speak a little bit more about that opportunity and what the economics look like beyond just lasers and for the full module? Michael E. Hurlston: Yes, Chris. Yes. No, we -- again, first, appreciate how much time you're spending on the company. Yes, we've got our first ELS module order right? Which from an ASP standpoint is meaningfully higher than the set of lasers that we ship in. So we're very excited about the revenue opportunity, small to start, right? And we said that we'd be shipping sometime midyear, early second half of '27 to be honest, a little bit later. We felt like we'd see more opportunity on sort of scale-out applications than we have to date. But we're very pleased to be participating in the early phases of scale up with both lasers and now with the ELS module. As I said a minute ago, the ELS module meaningfully higher from an ASP standpoint, but the margins are not quite as good. Above corporate average, but not quite as good as the lasers. So we're trading a little bit of margin to get some revenue bump. We think -- I think Simon asked earlier in the call, we think we have enough drivers on the margin side that we can keep the margin vector moving, but help our revenue acceleration. Wupen Yuen: Also just a bit to add, right? If you recall that we've positioned our ELS module to be really enabling the customers who don't want to deal with individual laser chips. So this is really a very first step for us to take to ship to one customer and then go from there, we enable other end users to use the ELS, enable their CPO and NPO systems. Christopher Rolland: Excellent. Maybe as a follow-on, I think, Michael, you've talked about, I think it's the 1.6T cycle or 200 gig per lane and perhaps CW and SiPHo working into the supply chain maybe earlier and being a larger part of transceiver shipments ultimately. I guess, first of all, where are we on that? Is this on the SiPHo CW side accelerated even faster than you originally spoke about. And can you kind of describe the difference in economics for you between CW lasers and EMLs, which would be, I think, larger because they contain the modulators as well. That will be great. Michael E. Hurlston: Okay, Chris, yes, good question, and I'll give some commentary, and then have Wupen comment as well. So one, no slowdown in our EML demand. I mean we are -- I think it was Papa that asked a minute ago, we see still a significant supply/demand imbalance on CW or EMLs. As Kathy put in the prepared remarks, we're still very much on track to increase our EML output year-over-year. But even at the end of the year, we'd expect to be significantly behind demand. So no slowdown at all in the demand that we're seeing from EML. We acknowledge and we've said this before, that we would expect and are seeing CW lasers take a significant portion of transceiver output. Silicon photonics is a viable solution at 1.6T. Of course, we've also said, and it also seems to be bearing out that as we think about 3.2T, silicon photonics loses some of its advantages, and we'd expect to see EMLs come back in a meaningful way. What I comment is, a little bit of a shift in stance is that we are allocating some of our output now because we're actually doing quite a bit better in Japan than we expected in terms of output. And so what we're doing is part of that is allocating some of this excess output to CW lasers and we're now shipping CW lasers in a relatively meaningful way in this 200-gig per lane silicon photonics opportunity. What's also changed for us is we have significantly reduced the die size of our CW laser. So before when you and I talked, we said, hey, probably from a margin standpoint, EML is better. Now we brought things much more in line. CW lasers are smaller. They're better performing. We are commanding a significant price premium, as I said in a previous question, against what we view as the market price because of the performance of these lasers. And as such, the margin opportunity is still better EMLs, but that gap has closed considerably, I think since the last time we talked. Wupen, do you want to talk a little bit about the dynamic that you're seeing on CW and EML? Wupen Yuen: Yes, Michael, I think I hope we're accurate, right? Just a couple of things to add to that. Number one, if you look at the application today, there's a lot of 200 G per lane volume that's on 800 gig. And then in that, we actually see a much higher EML share versus CW laser share. So Michael, talked about dynamics. I think this will continue. EML will remain a very important player in 200 G per lane. But as 1.6T ramps up, I think we will see more CW lasers as Michael talked about, our new design of 200 G CW laser is much more efficient, therefore smaller. It gave us a much better gross margin profile. Another thing also of note, really, dynamics here is that in a constrained environment, we'll also see customers' behavior as wherever they can get the laser source, they will use that solution to support their build-out. So the dynamics of EML/CW lasers is not only a technical one, but also a supply versus demand situation. Operator: Your next question comes from the line of Vijay Rakesh with Mizuho. Vijay Rakesh: A good quarter and guide here. Just a quick question on the 200 gig per lane EML and CW, it looks like that's ramping very nicely. Is it fair to assume both the 200 gig EML and CW laser should be accretive to your margins? And when do you see this 1.6T crossover, it looks like it's already greater than 25% revenues. But when do you see that crossing over with the [ 800 G ], I guess, and a follow-up. Michael E. Hurlston: Yes. Mr. Rakesh. Good to hear from you, my friend. Look, no change really in the forecast on the crossover. What we said is -- and I think you're referring to 200 gig per lane lasers. We have said that for us, we'd expect 200 gig EMLs to be the majority volume shipments by the middle of 2027. We just said in the prepared remarks that now 200 gig per lane EMLs are 25% of our mix. We'd expect it to be 50% or more of volume by midyear of 2027. So we seem to be tracking to that. No real change in that. I think generally speaking, yes, you're right, lasers are one of our better businesses, and the lasers are more than -- our corporate accretive, the CW or EML. And as I said to Chris a minute ago, we've closed the margin gap quite considerably since our last call, on EMLs versus CW by shrinking the die size of the CW laser. So EMLs are still better, but we've closed the margin gap quite considerably. Vijay Rakesh: Got it. Very helpful. And then on the operating leverage side, Wajid, it looks like solid improvement there year-on-year, you already at your 40% target. How should we look at -- how should we think about it as you go through fiscal '27? Wajid Ali: Yes. Thanks, Vijay. So the guideline that we have given at $2 billion of revenue was 38% to 42%, like Michael said in his prepared remarks. We're already at the midpoint of that at much lower revenue levels. And so with gross margins improving as we approach $2 billion, we'll see some improvement on the operating margin line as well that corresponds to those gross margin improvement. So think of the 42% outlier more as a midpoint with the range, probably moving up 100 to 200 basis points versus what we showed at OFC. Operator: Your next question comes from the line of George Notter with Wolfe Research. George Notter: Congrats on all the success here. I guess I wanted to ask about indium phosphide substrate supply. I was really intrigued by the deal you guys signed in the quarter with AXT. Because I think a quarter ago, you actually said that you were doing pretty well on indium phosphide substrate. And so it feels like there's a bit of a change here. I guess I'm wondering like what you guys are seeing longer term here in terms of your need for more indium phosphide substrate. And as I extrapolate that kind of look at Greensboro, are you making more progress towards filling the rest of that facility looking forward? Michael E. Hurlston: George, yes, look, I would agree. I mean I think what we tried to hint to in a previous question is the ultra-high-powered laser demand has surprised us, and that cuts across a couple of customers. So what we're trying to do, I think really in the last 3 months is secured even more substrate supply. We were doing well. We felt like we had given the baseline of demand that we were seeing from ultra-high-powered and then, of course, the EMLs, the CW lasers that go into our scale-out products. We felt pretty good, right, as you said. But I think we've seen a pretty big surge in demand, as we said. And in order to respond to that, we went out and we found additional substrate help from AXTI. They are a great partner. Wupen has worked with them for a good number of years. And we think we're going to need their help just given the surge in demand. So that's what drove that deal. If this vector continues, we're probably going to need to look for more help on substrate. We feel we're good at this moment. We're probably pretty comfortable just given our lead in arrangement with the Japanese supplier and now of the announced deal with AXTI. But given the rate of change in the demand vector that we're seeing, that may not be true a quarter or 2 from now either. George Notter: Got it. And then do you think it's likely that we could see you sign some LTAs for more of the capacity in Greensboro. Is that a possibility? Michael E. Hurlston: Yes. Look, we're looking to do that. I think we've sort of reported consistently that we have capacity in Greensboro. We have room there and Wupen has been out talking to a number of customers about helping them with their laser demands, which are, again, changing minute by minute is that everybody starts to look to adopt near-packaged or co-packaged solutions. And so I would expect that we have some things to talk about over the next couple of quarters relative to new arrangements in Greensboro that speak to more of this capacity we have there. Operator: Your next question comes from the line of Tom O'Malley with Barclays. Thomas O'Malley: My first is on the NPO side where you spend a little more time on the preamble talking about the technology. I was curious, when you look at ASIC and GPU road maps, when you see the intersection of NPO, does that need to be with a new generation of silicon or can you intersect an existing ramp. If you were to see a big customer today ramping in the beginning of next year, were you able to ship NPO solutions where they originally started off as electrical-only solutions just for the timing aspect of your ramp, that would be super helpful. Michael E. Hurlston: Yes. Tom, super to speak to you again. We really appreciate this chat, as always, Tom, as always. Look, I think what we're seeing now is an inflection in the ASICs and in the SerDes speed, and that's driving the need for NPO and CPO. I don't know, and Wupen can comment a little bit on this. I don't think there are existing TPUs, XPUs, GPUs that are shipping that have a fast enough SerDes speed that we could suddenly plop in an NPO or CPO solution, which I think is what you're asking. But as these new generations come online, really seeing silicon in mid-'27 toward the end of '27 and early '28 all those new silicon solutions, again, GPUs, XPUs, TPUs all seem to be driving SerDes speeds that are consistent with the adoption of NPO or CPO. Wupen, any color you can add for Tom? Wupen Yuen: Thank you, Michael. I think that's very accurate. Really, I don't think, Tom, we are not seeing kind of the retrofit of NPO onto the current XPUs. We're seeing really, like as Michael talk about, there is a broad momentum towards the '28, kind of '28 ramp of NPO and CPO and really driven by optical scale-up. So it's not -- this is beyond just the XPU itself. This also goes into a rack-based multi-rack system that requires optical scale-up, right? Therefore, we believe this is going to be new processor, new racks and there's 2028 event for optical scale-up from the industry's evolution point of view. Thomas O'Malley: Super helpful. And then on the other side of things on OCS, you talked about in-tray OCS. I was curious, is the competitive dynamic there similar for you guys? In terms of the timing, is that in your current TAM? Or would that be additive to the TAM? And when do you see that intersecting in terms of that technology hitting the market? Michael E. Hurlston: Tom, additive, right? So anything that Kathy's presented at OFC, it's above and beyond that. It's a very new set of opportunities. We've come to find out there are a number of different folks that are looking at this kind of approach, and it's all very additive. It would hit for us '28 timeframe, Tom. It's not something that's super imminent, but it's imminent enough that we're working on it aggressively. It requires a lot of redesign on our -- from our engineers. But look, we're the only guy shipping. I mean I know a lot of people are talking about OCS a lot of start-ups for us to be now at $100 million and beyond types of quarters, we're the only ones that have a track record outside of a contract manufacturing relationship with a large OCS users. So we're really the only merchant supplier today of OCS. And by virtue of that, we're going to get every single call and have the first look, I think, in every single opportunity out there. Kathryn Ta: And Matthew, it looks like we have time for just 1 more question. Operator: Great. Your next and final question will come from the line of Ruben Roy with Stifel. Ruben Roy: Great. Thanks for sticking me in here. Michael, maybe just to drill into the Pump Laser commentary a bit, growing quite nicely. I think you said 80% year-over-year for the second consecutive quarter and fourfold increase coming still effectively sold out. Can you talk a little bit about where you are in the Rose Orchard ramp and what exit capacity looks like. And then you talked about some long-term supply agreements that you're putting into place for scale across. Can you characterize maybe high level, what the structure of those agreements are and the duration? Michael E. Hurlston: Yes, Ruben, best for last. We really always appreciate your questions. I think this is an area of incredible strength for us, right, which really I think is underappreciated. We have a very large market share here. And what we've done is really worked hard with, for example, a lot of the NEMs, the network equipment manufacturers to form strategic partners. And we're super pleased with how people have come to work with us on helping offset some of the CapEx, and it's considerable that we have to put out to ramp in Rose Orchard. You got it right, and to then bring that into our Thailand manufacturing for packaging and tests. We formed a series of arrangements that for the most part, our 3-year arrangements. And those arrangements -- as our normal arrangements, have pricing built into them, there are pricing levers that we can exercise if certain conditions are met. So we think we have some room there on the price line. But these are giving us a lot of surety in terms of that demand not evaporating. And in most instances, I think they're take-or-pay, Wupen, comment since you have been the middle of that. But we feel really, really good about where we're sitting, Ruben, on the pumps. Again, rough order, we're somewhere between 70%, 80% share. And we believe we have a technology road map that our customers want to engage in that will afford us the opportunity to work on price to further increase output. But this is a darn exciting area for us. Wupen, any additional color? Wupen Yuen: No, thank you. Ruben Roy: That's really helpful. For the last 30 seconds here, a lot of discussion on NPO. My quick follow-up on that is, are the discussions, engagements, that type of thing associated with some of the open or standards-based NPO kind of, yes, I guess the standard-based NPO versus custom. And I'm asking, I'm just wondering if there's a better alternative for you given your technology and positioning. Does that matter... Michael E. Hurlston: Look, I'll have Wupen to comment just in the interest of time. I mean there are OCI, like different standards that are coming out that are talking about the way the interface between the ASIC and the optical engine, for example, that's great for us because that opens up switch opportunities, for example, that may not be open to us before. So the standards-based approach is -- opens up optical TAM. But we are engaged to be honest with you on both, right? There are a lot of custom, very specific types of implementations that our customers are driving to. And we are -- that's really going to be our first wave of NPO engagement moment, Ruben. Any color? Wupen Yuen: Maybe a little bit of color. I think just the -- to the extent what Michael just talked about, right, there is actually 2 things. One is that today, right, the physical level, the optical level, they're all so called fast narrow, 200 gig per lane, massive lanes. And the next generation, right, as Michael talked about will be like OCI/MSA based, right? So that's on the optical side. But on the form factor side, it is very much proprietary, right? Everybody has a different design. Again, we talked about earlier, matched to their rack design, their system design, and that actually is different from customer to customer, right? So again, optically, they are kind of standard based, but then on the competition side, they're different between different customers. Operator: Thank you for your questions. I will now turn the call back to Kathy for closing remarks. Kathryn Ta: Thank you, Matthew. That is all the time we have for questions, and we look forward to connecting with you at upcoming investor conferences and meetings throughout the quarter. With that, I'd like to thank you for joining us today. Operator: This concludes today's call. Thank you for attending. You may now disconnect.

Shares of optical technology leaders Lumentum Holdings Inc. (NASDAQ:LITE) and Coherent Corp. (NYSE:COHR) experienced some action after the quarterly reports. During the August 12 episode of CNBC's Mad Money, Jim Cramer highlighted the short-term disconnect between market trading dynamics and business fundamentals in the optical hardware space. He noted: The optics rally was set off by Lumentum Holdings Inc. (NASDAQ:LITE), which reported FQ4 2026 net revenue of $1.01 billion, up 109% year-over-year, beating consensus estimates. Non-GAAP diluted earnings per share reached $3.23, topping Wall Street expectations by $0.26. Lumentum issued upbeat guidance for Q1 fiscal 2027, projecting net revenue between $1.225 billion and $1.275 billion with non-GAAP EPS of $4.05 to $4.35. The company’s non-GAAP operating margin is projected at 39.5% to 40.5%. The beat-and-raise report sent Lumentum shares surging and sparked a rally across the photonics sector. Coherent Corp. (NYSE:COHR) delivered a strong FQ4 2026 report of its own. The company posted net revenue of $2.05 billion, a 34.0% year-over-year increase, surpassing consensus estimates by $70 million. Non-GAAP EPS came in at $1.74, beating Wall Street expectations by $0.12. For Q1 fiscal 2027, Coherent provided a strong guidance, forecasting revenue between $2.2 billion and $2.4 billion along with non-GAAP EPS of $1.85 to $2.05. Non-GAAP gross margin is expected between 39.5% and 41.5%, with non-GAAP operating expenses forecasted at $400 million to $420 million and an effective non-GAAP tax rate of 18% to 20%. However, despite top- and bottom-line beats and strong forward guidance, Coherent shares slid in after-hours trading. As Cramer observed, the after-hours dip was a textbook "sell-the-news" reaction after the stock had already gained over 8% during regular hours in anticipation of the results. Smart money positioning reflects rising hedge fund interest across the two names despite elevated valuation multiples. Lumentum Holdings Inc. (NASDAQ:LITE), trading at a forward P/E of 43.10, saw hedge fund holders jump to 123 in Q1 2026, up from 97 in the prior quarter, though accompanied by a higher short interest of 12.16% of float. On the other hand, Coherent Corp. (NYSE:COHR) carries a more moderate forward P/E of 32.89 and counted 114 hedge funds holding positions in Q1, up from 109 previously, with a lower short interest of 5.42% of float. While short-term trading dynamics and valuation-driven pullbacks can cause temporary volatility, both companies continue to show strong multi-quarter demand visibility across their optical networking portfolios. As long as hyperscalers continue scaling massive AI clusters where optical transceivers serve a critical bottleneck, both companies are positioned at the epicenter of multi-year secular growth. While we acknowledge the potential of LITE and COHR as an investment, we believe certain AI stocks offer greater upside potential and carry less downside risk.

The gain was set before the results crossed, and its optical peers rose with it. Coherent (COHR) stock gained about 9% on Wednesday, which reads like a market applauding a good quarter. The timing says otherwise. The fourth-quarter results did not cross until after the closing bell, so the entire session's gain was locked in before anyone outside the company had seen a figure, and the coverage that followed the release reported the stock slipping despite the beat. Its Optical Peers Rose That Same Session The tape points away from anything Coherent-specific. LITE gained 13.6% over the same window, MKSI 4.2%, IPGP 1.8%, against 0.3% for the S&P 500. The day was framed in advance as a same-session read on the AI networking build-out, with Cisco Systems also reporting after that close, and buyers who could not yet have seen either set of numbers paid up across the group. That is exposure to a theme, not to a company, and a single session can reprice an entire group. The Trefis High Quality Portfolio does not depend on the handful of largest technology names to produce its returns. Indium Phosphide, Not Orders, Sets The Ceiling Coming into Wednesday, the stock was already up about 205% over the trailing year. On a run like that, a beat and an above-consensus outlook are the price of admission, not a surprise. The fiscal Q4 report (ended June) put record revenue of $2.05 billion on the board, up 34% year over year and 42% excluding two businesses sold during the year, with data center and communications at 79% of the total. What the report did not settle is how fast that demand converts into product. Management names Indium Phosphide capacity as the primary constraint, and Indium Phosphide lasers are what sit inside its 800G and 1.6T transceivers. The company produced about 80% more of those lasers in the June quarter than a year earlier, and yields on its 6-inch lines in Texas and Sweden are running above those on its 3-inch lines. Watch The Ramp, Not The Reaction Management expects internal Indium Phosphide output capacity to double year over year by the end of the September quarter, a quarter ahead of the original plan, with guidance for that period of $2.2 billion to $2.4 billion. Beyond transceivers, first revenue from co-packaged optics is expected in the December quarter, carried by ultra-high-power CW lasers that its Texas plant has begun to ramp. Those two ramps decide whether the order book turns into revenue. The stock itself is the noisier variable: in the six sessions before Wednesday it rose 13.4% on one day and fell 14.2% on another, which is a wide swing for a business whose order book management describes as booked out. If you are sizing a position around the next print, the useful record is how this stock has actually traded through its own earnings, rather than how it traded into this one. A Ramp Is A Schedule, And Schedules Slip Coherent's demand looks booked, but its delivery runs through one material and a small number of plants, and that is timing risk no single position can spread. The Trefis High Quality (HQ) Portfolio is built the other way, as a system rather than a bet on one company's schedule. That portfolio has a track record of outpacing the three major indices - the S&P 500, S&P Mid-cap, and Russell 2000.
