The company is Applied Optoelectronics, or AOI. That company is largely based a little bit down the road from NASA’s Johnson Space Center today, in Sugar Land, Texas.

This is a company that has run from $15 a share to $200 plus per share in the last year. These things take me a few days to put together and publish, so there’s a good chance that by the time you’re reading it, it’s nowhere near $200 a share. Could be back down at $15, could be up at 600. We just don’t know.

But part of this publication is not always finding the perfect companies to buy. It’s digging in and understanding what these companies are, what they do, and then ultimately making a decision as to whether now is the right time, or whether maybe there’s just not enough juice left in the squeeze. That’s a perfectly fine outcome too.

So ultimately, we’re looking to answer whether there is a valid business under all this, or whether it’s all smoke and mirrors that will eventually lead to ruin for those that are getting in at this $200-per-share mark.

What is AOI?

AOI is a vertically integrated optical maker. If that means nothing to you, don’t worry, because hopefully by the end of this section it will.

Now all around us we have cables, and those cables are sending data back and forth. As I write this I am watching the Stanley Cup Finals on a TV that has an HDMI cable. That HDMI cable sends a signal back and forth. It has Ethernet plugged into the back of it, and that Ethernet is sending a data signal back and forth.

Now most cables that we interact with, most cables that we’ve dealt with over our lives, have been made of copper. Copper is great. Copper can send these signals for decently long distances and it has a lot of strengths. Ultimately, when it comes down to it, copper just can’t handle fast signals, and the world that we are rapidly heading towards requires fast signals.

If you look at the data center buildouts that are happening, these data centers all have racks and racks of GPUs. To be able to build the types of models that we are seeing from these AI powerhouses, you need to be able to connect GPUs, and you need those connections to be fast. That’s where optical makers come in. They are not building these connections out of copper wires any more. They are building these connections out of lasers and light.

And that’s where AOI sits. It helps make these transceivers and the technologies that are required to send a signal back and forth between different racks in these data centers. Sounds simple, but there’s actually a lot of tech that goes into it.

Right now the product that is really driving the price in AOI up is called an EML transceiver. This particular piece of technology helps send a signal back and forth between different racks, or between wherever you need that signal to go. Right now 800G is the big buildout. All the data centers want 800G. This is a 100Gb connection across eight different lanes, which means you can send a ton of information back and forth. A lane is just one of those parallel streams of light. Stack eight of them at 100 gigabits each and you land at your 800 gigabits.

There’s a lot of fun physics that I got into as part of researching for this article, which I won’t bore you with. I was actually pleasantly surprised by a primer on the physics that Claude provided me. So, yes, I definitely used some transceivers in the making of this article.

Alright, where were we. AOI. Well, the thing I want to call out here is that this is not AOI’s first rodeo when it comes to catching onto a massive buildout trend, and it’s actually one of the most alarming things I found about this company. AOI is a pretty old company. It’s been around for a good long while. It’s been in the cable business. It’s been in all kinds of businesses. It’s been around that long.

In 2017 the stock had explosive growth on the back of Amazon. So Amazon shows up, they’re building AWS, and AOI was the company that was helping them build the transceivers for it. Instead of 800G this was 40G and 100G at the time. This sent AOI stock up to $100 a share into 2017, and it ultimately ended up busting down to $1.48 when it turned out that Amazon didn’t need anywhere near the volume everyone had built up for.

I mention this not as a guarantee of the path that we’re on, but just to highlight that we have been on this exact path before. The parallels are eerily similar. In 2017 Amazon was by far the largest customer, and the ten largest customers AOI had made up greater than 95% of the company’s revenue. In 2026 the concentration is just as extreme. The top ten customers again make up more than 95% of revenue, and just two of them, a cable distributor named Digicomm and Microsoft, are better than 80% of the total. Different names, same shape. Not a guarantee of things to come, but a path to be wary of.

And this kind of thing happens because of cyclicality. We will touch on cyclicality later in the article.

The Technology Transition

800G, as we have mentioned, is EML. There are a few different types of products that exist in this space, but 800G is dominated by EML, and EML happens to be exactly what AOI is built around.

What is going to happen as we move forward is a significant shift in how the market works. This shift happens at 1.6T, and especially at 3.2T, where silicon photonics takes share and the value migrates from this high-margin EML to cheaper CW lasers.

The next question you probably have is whether AOI is participating in 1.6T. Yes, AOI is a real 1.6T participant. But what we need to be aware of is that it will not be a dominant participant in CW lasers, where there are already significant competitors. It’s also a world with lower margins, and a world that is more contested.

The good news, though, is that one of AOI’s significant advantages still plays out in the CW laser space. Their vertical integration. In late 2025 they announced their own high-power CW pump laser aimed right at silicon photonics and co-packaged optics, which is their way of trying to keep a foot in the next generation rather than just defending the last one.

We touched on vertical integration above but did not go into it in depth. A thing worth knowing about AOI is that it is incredibly vertically integrated. It goes all the way from growing the crystals that are required in the end product, all the way to delivering the end product. Competitors have to rely on others for different parts of this. AOI simply does it all itself.

And AOI is building the newest of this capacity, the 800G and 1.6T lines, inside the United States, down in Texas. Right there are two things that work in AOI’s favor versus its competitors.

AOI is not the market leader in high-end EML lasers. That title belongs to Lumentum. It is not the leader in 800G module volume. That title belongs to InnoLight. But AOI’s real edge is that it makes its own lasers and its own modules, in the United States, from the ground up. It’s not waiting in Nvidia’s allocation line, and it’s geopolitically very clean.

Competitors

There are a number of competitors in the space. You have the aforementioned Lumentum. Lumentum is the EML laser leader. This is the 800-pound gorilla in the room when it comes to EML lasers. They own about 60% of the market and they’ve been rewarded heavily for it. This is roughly a $70 billion company at the time of writing, and it has run more than tenfold over the past year. It was one of the best-performing stocks in the entire S&P 500 this year, and it just joined the Nasdaq-100.

Coherent is another competitor. Coherent broadly builds EML plus SiPh. SiPh is cool, or silicon photonics. This is the technology of building the optical circuits directly onto standard silicon microchips.

InnoLight and Eoptolink are the volume module leaders out of China, and they compete on a pure cost basis. These are the companies that pump stuff out cheap. Sometimes cheap is good, but this is also a supply chain risk, which is part of why AOI stands to benefit from being stateside.

I called Lumentum the gorilla in the room, but the true gorillas are companies like Broadcom. Broadcom makes the DSP chips and the switch silicon that sit at the very center of these networks, which is a different layer from the lasers and modules AOI builds. DSP stands for Digital Signal Processing, and it is the chip inside a transceiver that cleans up the signal so it survives the trip. Broadcom builds those for 800G and 1.6T, and it is also out front on CPO.

And CPO is another term you’ll want to be familiar with if you are interested in investing in semiconductors. CPO stands for co-packaged optics. Traditionally a switch chip uses electrical traces to send data to pluggable lasers on the front edge of the server rack. CPO integrates the optical silicon directly next to the switch ASIC on the same package. So it eliminates the copper travel distance, slashes power consumption, and reduces latency for these massive hyperscale networks.

Amongst all these names, AOI is the small, vertically integrated Western player. Of all the Western InP laser makers it is the smallest, which generally means it’s got more room to grow.

The Financials

Let me walk you through the numbers, because this is where the story gets real on both sides.

Start with the top line, because the top line is the whole reason anybody is paying attention. In 2024 AOI did about $249 million in revenue. In 2025 it did about $456 million. That’s an 83% jump. For 2026 management is guiding to more than $1.1 billion, which would be better than doubling again. So you’ve got a company going from a quarter of a billion to over a billion in revenue in two years. That is the kind of slope that takes a stock from $15 to $200.

The most recent quarter, Q1 2026, reported on May 7, was the fourth record quarter in a row. Revenue was $151 million, up 51% from a year earlier. Data center was $81 million of that, more than half the company now and up over 150% year over year. Cable chipped in $67 million. So the AI data center business has officially become the main event.

AOI still loses money, and I am not going to dress that up. Q1 was a GAAP net loss of $14 million. Gross margin was about 29%, which actually slipped a little from the quarter before as the data center mix grew. One detail the headlines skipped right over: of that $81 million in data center revenue, only $4.6 million was actually 800G. The big 800G ramp hasn’t really happened yet. What grew in Q1 was the older 100G and 400G product. The 800G wave, the one this whole thesis rides on, is a second-half-of-2026 event.

This matters, because AOI has never put together a sustainably profitable year in its entire life as a public company, going all the way back to its 2013 IPO. Full year 2025 was a loss of about 26 cents a share.

So why does anyone care? Because management says that changes this year. They are guiding 2026 to more than $140 million in non-GAAP operating profit, and they expect to flip to non-GAAP profitability starting in the second quarter. They’ve laid out 60% to 80% sequential revenue growth in the back half as new Texas capacity comes online, with gross margins climbing to 35% by year-end and over 40% in 2027. A company that crosses from years of losses into real profit while doubling revenue can re-rate hard. That’s the bet.

And the number management keeps pointing at sits even further out. On the call the CFO put a hard figure on mid-2027: roughly $471 million a month in data center transceiver revenue. Annualize that and you get about $5.65 billion in transceivers alone, before a dollar of cable. The current full-year guide is $1.1 billion. So management is telling you the exit speed eighteen months out is something like five times this year’s number. The CEO literally called this year’s $200 million-plus orders small compared to what is coming.

Last, the balance sheet, because building laser factories is not cheap. AOI exited Q1 with about $449 million in cash, but a big chunk of that came from a $382 million stock raise during the quarter. There’s also $125 million of convertible debt due in 2030. The company is spending heavily on capex, burning cash, and funding the buildout by issuing stock. That keeps the lights on and the factories going up, but it means the share count keeps creeping higher, and every new share is a slice of the pie taken out of the existing owners’ hands. Hold that thought for the bear case.

Cyclical or Structural

I promised we’d come back to cyclicality, so here we are. Everything in the bull and bear cases below hangs on it.

The optical business has always been cyclical. Wildly so. If you’ve ever looked at memory chips, at companies like Micron or SK Hynix, you know the pattern. Demand grows for a couple of years, everybody races to add capacity, capacity overshoots, prices crash, and the whole industry has a miserable year before it does it all again. Optical transceivers have run on that same rhythm for two decades. The firm LightCounting, which tracks this market more closely than anyone, has pointed out that every two or three good years gets interrupted by a flat or negative one. And the down ones are not gentle. The last big cycle, the 2017 to 2018 one that AOI rode and then got crushed by, saw these stocks fall 50% to 70%.

So how does that happen, mechanically? It usually isn’t pure overbuilding by itself. It’s the inventory whipsaw on top of it. When parts are scarce, customers panic and over-order from every supplier they can find, building a stockpile just to guarantee they get their allocation. The moment the shortage eases, they cancel the duplicate orders and start working down that stockpile. Reported demand falls off a cliff even though the real end demand is fine. Then, because everyone added capacity during the boom, there’s now too much of it, and suppliers start competing on price. That’s the cycle. And the dangerous part is that it tips right at the moment the shortage ends.

LightCounting expects the current laser shortage to ease around the middle of 2026. They are explicitly calling for a flat quarter or two in late 2026 as the supply chain finds its footing. That is the next test.

Now the other side. This time might genuinely be different, at least in degree. In every past cycle, one speed generation ramped, peaked, and got replaced by the next, in sequence. This time the generations are stacking on top of each other. 800G is ramping, 1.6T is ramping right behind it, 3.2T is coming, and co-packaged optics adds a fourth layer behind that. Because demand is spread across so much of the stack at once, no single generation’s inventory hangover can sink the whole thing the way the 100G glut did in 2018. That is the single best argument that the next downturn could be shallower than the last.

The demand itself has a self-feeding quality this cycle. Every new AI model generation increases the amount of inference running, which means more hardware, which means more optics, on a loop. And the network is eating a bigger and bigger share of every data center dollar as clusters get larger. So the trend line is real, and it is steeper and more durable than memory’s ever was.

But, and this is the honest synthesis, structural growth and cyclicality are not opposites. Memory demand has compounded for forty years and memory is still the most violently cyclical business in tech. Both things are true at once. The market growing to $35 billion or more by 2030 and the industry having brutal down years on the way there are not in conflict.

The cleanest tell that even the biggest players expect the cycle to persist is this. Nvidia reportedly asked the laser supply chain to build 20 times more capacity by 2030, and the suppliers pushed back and agreed to only 12 times (per Rosenblatt Securities’ May 2026 indium phosphide supply model). People who believed in permanent, non-cyclical demand do not deliberately under-build. They are hedging against the down year they know is coming.

So where do I land? This is structural growth wrapped around a cycle. The decade trend is up and to the right, steeper than memory. But there will be air pockets, the demand sits in the hands of a few spending-cyclical buyers, and the first real test arrives in the back half of 2026. For a company like AOI, which we’re about to see is concentrated, richly valued, and not yet profitable, the cyclicality is not a footnote. It’s the main risk.

Bull Case

Alright, let me lay out the bull case as strongly and as honestly as I can, because there is a real one here.

It starts with a moat that’s easy to miss. Everybody in this industry can design an 800G transceiver. The incumbents can all do it. The hard part is not designing one. The hard part is building enough of them, precisely, at a cost that scales. Inside every transceiver is a microscopic assembly of lasers and waveguides where a misalignment of a fraction of a hair kills the signal. And remember what we covered in the technology section: silicon cannot make light, so every one of these things needs an indium phosphide laser, and those lasers are the single most supply-constrained part of the whole industry. There aren’t enough of them, and the furnaces that grow them are booked solid.

AOI is different because it makes its own lasers. In-house. The exact part everyone else is fighting to source, AOI grows itself, from the crystal up. And it goes further than that. It builds its own automated production lines, and, more importantly, much of its own manufacturing equipment. So when the CFO got the obvious bear question on the call, which is, fine, demand is huge, but can you actually build it, his answer was that equipment availability hasn’t been a problem because they make most of the equipment themselves. While competitors line up for the same furnaces, the same merchant lasers, and the same third-party tools, AOI is not standing in any of those queues. The moat here is not a patent. It’s throughput nobody can copy on a short timeline.

Then there’s the order book, and these are signed orders, not a slide deck. In March, AOI announced its first volume 1.6T order from a major hyperscaler, worth more than $200 million, big enough on its own to put that one customer back above 10% of revenue. It booked a $53 million 800G order, then another $71 million one. That’s over $324 million from a single hyperscaler in about four weeks. And when an analyst asked why that $200 million 1.6T order stretches into 2027, the CEO’s answer was that it’s small compared to what’s coming in 2027.

Stack the capacity ramp behind it. AOI exited Q1 making about 100,000 of these units a month. The plan is 150,000 this quarter, over 650,000 a month by the end of 2026, and over 930,000 a month by the end of 2027, with more than half of that built on US soil. Management calls it the largest US production capacity for 800G and 1.6T.

Put it together and the bull case is this: a company that owns the scarce input, can build at a speed nobody else can match, is sitting on signed hyperscaler orders, and is about to cross from years of losses into real profit while its revenue multiplies. Add a genuine strategic edge in US manufacturing, which the hyperscalers increasingly want for supply security and tariff reasons, plus an Amazon that has tied its own stock warrant to how much product it buys.

But I want to state the bull case fully, including its shape, because the shape is the risk. The bull case, completely stated, is a pre-paid, high-beta execution bet on a 9x capacity ramp landing on schedule, into a demand environment that has to stay vertical. Every word in that sentence is doing work. Pre-paid, because you are paying for it now, today, before it happens. Execution bet, because the capacity actually has to get built. And demand that has to stay vertical, because if the AI spending cools, all of it cools with it.

Bear Case

Now the other side. A thesis you can’t argue against is not conviction, it’s hope. So here’s the honest bear case.

Start with the price, because the price is the problem. At around $200 the stock trades at roughly 15 times this year’s sales, for a company that has never strung together a profitable year. A lot of very good news is already baked in. As we’ll see in the valuation, even a genuinely good outcome is largely priced in today. That leaves very little room for error, and this is a stock that does not handle error gracefully.

Then the concentration, which is the biggest risk by a mile, and the one that should make the hair on your neck stand up given the history. The top ten customers are about 97% of revenue. Two of them are more than 80%. And AOI sells on purchase orders, not binding long-term contracts, so there’s no floor under any of it. The famous $4 billion Amazon figure is a discretionary ceiling, not a commitment. We’ve watched this exact movie before. In 2017 one giant customer was most of the revenue, the orders dried up, and the stock went from $100 to $1.48. Nobody is saying that happens again. But the structure that made it possible is sitting right there on the page, unchanged.

Next, the technology, which is the slow risk rather than the sudden one. AOI’s strength is the EML, and the EML is exactly right for 800G. But the industry is moving toward silicon photonics and cheaper CW lasers at 1.6T and beyond, and in that world the value drains out of the expensive part AOI is best at. AOI is in that race, but by Rosenblatt’s own numbers it is the smallest of the Western laser makers, well behind Lumentum and Coherent. So the bull case is partly leaning on a technology whose long-term share is genuinely in question.

Add that the profitability is still a promise. The 35% margins and the $140 million of operating profit are forecasts, not results. And the most recent quarter actually missed on revenue versus what Wall Street wanted, while the next quarter’s guidance came in a touch light. This is an execution bet, and the execution hasn’t been flawless.

Then the dilution we flagged earlier. The buildout is being funded by selling stock, and the convertible notes and the Amazon warrant are more shares waiting in the wings. Every per-share number in the bull case quietly assumes those new shares don’t pile up too fast.

A couple more. The insiders have been selling into this run, including the CEO offloading around $10 million worth and a director selling a block. Some of that is scheduled and perfectly normal, but into a vertical move it’s worth clocking. And the laser advantage cuts both ways. That 350% expansion of the laser fabs, plus a shift from four-inch to six-inch wafers, is exactly the kind of manufacturing transition where yield problems hide, and a laser yield problem is a revenue problem.

Finally, two longer-term clouds. There’s a quiet competitive threat from copper and from co-packaged optics. Active electrical cables can now handle the very shortest links (a point Credo hammered on its recent earnings call), and as those and CPO take hold, they can chip away at how many of these pluggable optical modules a cluster even needs. And the whole thing rides on the cyclicality question from the last section. If hyperscaler spending takes a breather, or the inventory whipsaw hits in late 2026 the way LightCounting expects, a richly valued, high-beta, concentrated name is precisely the kind that takes the 50% to 70% drawdown.

Like seemingly everybody in 2020, I started a YouTube channel. On that channel, I posted videos breaking down different kinds of companies, talking about investing, and occasionally teaching you how to build financial models. Some of those videos were on a company called Rocket Lab.

I have always been a fan of space, and I have always been a fan of investing. Rocket Lab caught my fancy. I pondered what could happen to this SPAC that had recently gone public and was being beat down along with every single other SPAC at the time. I saw a great future ahead for the company.

My problem was, especially if you look at some of the comments on the original video, I was far too conservative. I even had to defend a couple of my positions on Reddit, saying, “Hey, if I am too conservative, predicting here a more than 100% return in stock, then that is incredible.”

Rocket Lab has returned more than 3,000% since I made those videos saying that I was buying. My only problem right now is I wish I had bought more.

Here we are. I am writing this in May 2026. We are going to start out, right here on SpaceBreakdowns, with a deep dive into Rocket Lab. What has changed about Rocket Lab over the past few years, what the future looks like, and whether at $120 plus per share there is still room to run in this name, or whether it is finally time to sell.

Where Past Analysis Was Incorrect

In April 2024, I told you that excellent execution would yield a $20 stock. I was wrong. I modeled a traditional industrial business, but Peter Beck built an unassailable vertical monopoly. My models caught the trend, but missed the scale of institutional premium that we see today.

The Multiples Trap

In the April 2024 video linked here, I arrived at a long-term target price of $20 per share, assuming Rocket Lab had excellent execution. If Rocket Lab ended up at $20 a share now, I would be mind blown and extremely disappointed.

My thinking back then was that Rocket Lab should be modeled like a traditional high-growth industrial hardware company that would face multiple compression as its capital expenditure scaled. Instead, the market gave Rocket Lab a software-style scarcity premium, which is completely fair.

It is fair because Rocket Lab emerged as the only functional Western alternative to SpaceX. Wall Street threw standard EBITDA multiples out the window and re-rated them as a tier 1 national security asset. At $120 plus per share, I was wrong because I assumed the market would remain rational about valuation multiples for a hardware monopoly.

The Neutron Pricing Floor

In the first video I made about Rocket Lab in January 2024, I caught a lot of flak in the comments for modeling Neutron at a hyper-conservative $30 million per launch. The same feedback was on Reddit posts, and I made a second video that reran the numbers at the full $50 million retail price just to see the upside.

This was wrong, because even at $50 million, the model is treating launch as a static, commoditized line item. What actually happened by 2026 is that Rocket Lab began commanding premium block deals and National Security Space Launch phase 3 task orders. These defense missions do not just pay for the freight, they pay massive high margin premiums for custom orbit insertion, mission integration, and secure payload handling.

Rocket Lab being able to integrate all these parts was called out in those previous videos, but I never did acknowledge the value that would have on the pricing of Neutron.

Velocity and Margins of Space Systems

I correctly identified that Space Systems was the secret weapon, but I underestimated the sheer velocity of Rocket Lab’s vertical integration strategy.

By aggressively swallowing up the supply chain, capping it off with major moves like the Motiv and Mynaric integrations, Rocket Lab has turned space systems into an end-to-end captive powerhouse.

To be fair to my own modeling, I don’t believe anybody in early 2024 was modeling a 200 million dollar single quarter revenue run rate with 38.2% GAAP gross margins this early in the cycle.

Rocket Lab has very quickly ceased just being a component vendor and has become a prime contractor much sooner than expected.

The Q1 2026 Setup

I do not think there is any dispute that Rocket Lab had a fantastic Q1. The company had record revenue of $200.3 million. They now have a record backlog of $2.2 billion. They were able to sign 5 Neutron launches, and that manifest is now filling up through the end of the decade.

In addition, there were 31 Electron and HASTE missions booked, which is the highest booking Rocket Lab has ever had in a single quarter.

So far in 2026, there have been 8 launches year to date, and there are 70 more in the backlog. The 100th Electron launch for Rocket Lab should occur this year. There have been big partnerships with the likes of the Department of War, which signed a new launch contract for HASTE, and partnerships with Anduril to deliver new hypersonic capabilities for their national security program.

The key thing to pull out is the acquisition of the company Motiv and the completion of the Mynaric acquisition. Both of these acquisitions help expand how far Rocket Lab’s vertical integration can go.

Motiv brings space-proven robotics to the company’s offerings. As the company behind the Mars Perseverance Rover’s robotic arm and CADRE lunar rovers, they have put robotics systems on other planets that have been usable. This capability will now be available to Rocket Lab customers.

Along with robotics, Rocket Lab also added 7 new high-value products to its space systems lineup:

1. Electric propulsion, known as Gauss, which is a new in-house developed system for high-volume production

2. Optical payloads

3. Laser comms

4. Silicon solar

5. Star trackers

6. Robotics

7. Precision mechanisms

A popular line from Peter Beck is, “He who owns the payload owns the mission.” We can see from the steps Rocket Lab is taking that this is becoming more true over time. It is not new that Rocket Lab is trying to become the vertical integration play of space, but it is expanding how large that vertical offering actually is.

Over the years since I started covering Rocket Lab, it has gone from something that could put a satellite into space to a company where you can go and say, Hey, I want to build a robot that will go digging on Mars. Can you help me with that? And the answer is yes, 100%.

Rocket Lab can now design that robot, launch that robot, deploy that robot, and monitor and maintain that robot. All you need is the idea and the money to make it happen, and Rocket Lab will do that for you.

Overall, it was a fantastic quarter for Rocket Lab. They are the dominant Western alternative to SpaceX. SpaceX is the 1,000-pound gorilla in the room, but Rocket Lab is showing that they have the ability to be a major space company right alongside SpaceX. They may not dominate launch like SpaceX, but they are tackling a piece of the puzzle that nobody else is. That in itself is valuable.

The Bull Case

At the time of writing, Rocket Lab is a $72B company. You do not have to look back that far in the past to a time when it was a $10B company. To have gone from those levels up to $70B in such a short time is incredible.

At those levels, Rocket Lab is trading at approximately 25x forward 2027 revenue. The question is not whether that is expensive in absolute terms, as it obviously is. The question is whether Rocket Lab can continue to grow from these levels and prove that it is a company that is worth that much.

While we are not making buy or sell recommendations as part of this publication, it is worth talking about the price of Rocket Lab for just a minute. There are, I believe, 3 pillars that justify the valuation Rocket Lab is trading at today.

Pillar 1: Neutron

The first pillar is, of course, Neutron. Neutron is the shiny new thing and rightfully so. It is Rocket Lab’s medium-lift, partially reusable rocket that’s designed to put 13,000 kg into low Earth orbit. Makes it a direct competitor to SpaceX’s Falcon 9. A first launch is currently expected no earlier than the last quarter of 2026. The first stage is designed to be recovered on an ocean barge that they’re calling Return On Investment, for reuse.

Now Neutron matters but it’s not just for the launch revenue. The biggest story around Neutron for me is the flywheel. If you are a customer coming to Rocket Lab for a medium-lift launch, you are already more likely to use their components on your satellite. You’re more likely to use their software and you’re more likely to integrate with their broader space systems offering.

The inverse of that is also true. If you are already a Rocket Lab Space Systems customer, the launch decision becomes a natural fit. Neutron is not just a rocket; it is the gateway product that pulls everything else through.

This is a meaningful difference between Rocket Lab and a traditional launch provider. Rocket Lab is not selling Neutron the way ULA sells Vulcan or Arianespace sells the Ariane 6. They are selling Neutron as part of a bundle that competes on integration rather than just pure price per kilogram.

Pillar 2: Space Systems, The Prime

The second pillar is the one I underestimated the most in my early modeling. Rocket Lab is fast becoming the prime contractor for getting to space. If you have an idea for a mission, you go to Rocket Lab. It will design the satellite, build the components, integrate the payload, launch the rocket, and operate the spacecraft in orbit.

The Motiv acquisition is the move that crystallizes this thesis. Motiv built the robotic arm on NASA’s Perseverance rover and is delivering hardware for the CADRE lunar rovers. Rebranded as Rocket Lab Robotics, this isn’t just a component-supplier acquisition; it’s a full-on credentials acquisition. Rocket Lab can now credibly bid as a prime on planetary missions that previously belonged to JPL contractors and legacy primes. You combine that with the Mynaric acquisition for laser communications and the introduction of seven new high-value products in their space systems line up in Q1. Rocket Lab has closed most of the remaining gaps in their vertical integration play.

Peter Beck has always been explicit about the playbook: “Our acquisition strategy is simple but proven and effective. We identify the best space technologies that have struggled to scale and we bring them into the Rocket Lab ecosystem. By applying our resources, expertise, and manufacturing scale, we make these technologies more accessible and affordable for the global space industry.”

The Motiv deal is Rocket Lab’s seventh acquisition since 2020. Seven acquisitions in five years is not a side project. It’s a deliberate roll-up strategy that is aimed at making Rocket Lab the only place you need to go if you want to get to space.

If Rocket Lab succeeds in becoming the default prime for space access (in the same way that Heico became the default prime for aerospace replacement parts), the addressable market is substantially larger than launch alone. Space Systems revenue is growing faster than launch revenue. It carries a higher margin and benefits from the kind of switching costs that pure launch businesses alone do not have.

Pillar 3: Flatellite and the Constellation Play

The pillar 3 is the fun one and it’s the one that most people do not seem to be pricing in or talking about with Rocket Lab. In 2025, Rocket Lab announced Flatellite. It’s a flat stackable mass-producible satellite that is designed for large constellations. Beck himself described it as “a bold strategic move toward Rocket Lab operating its own constellation and delivering services from space.”

And Rocket Lab has rarely been shy about indicating that they will build their own constellation one day. Reporting from SatNews suggests that Flatellite is being aimed at 5G non-terrestrial networks, with industry chatter putting the minimum viable constellation in the 150 to 200 satellite range rather than the thousands required for Starlink-class build out. Beck’s own framing is: “By having our own rides to space with Neutron and Electron and being able to build our own spacecraft in high volumes, we have a distinct advantage when it comes to deploying constellations with speed and cost efficiency.”

To return to a quote we have earlier in the article, “He who owns the payload owns the mission.” The natural endpoint then of Rocket Lab’s vertical integration strategy is not just providing the rocket, the components, the spacecraft, and the operations to other people. It is operating its own services from space and capturing the revenue that flows to constellation operators rather than to their suppliers.

And this is obviously the part of the story that is hardest to value because it is the furthest from today’s revenue but it’s also the part that justifies multiples that look insane today. Starlink is on track to do somewhere in the neighborhood of $12 billion in revenue this year. If Rocket Lab can build even a meaningful niche position in 5G non-terrestrial networks over the next decade, that is not a $70 billion company. It is something much larger.

Of course the competition is real. Starlink dominates, Kuiper is coming, AST Space Mobile is in the market but this planet is large. The demand for connectivity is growing and the regulatory and capital barriers favor companies that already have the launch and manufacturing infrastructure in place. Rocket Lab is one of perhaps four companies in the world that can credibly stand up a constellation from scratch.

The Bear Case

There is a lot of expectation riding on Rocket Lab at these levels. At roughly 25x forward 2027 revenue, the market is pricing in flawless execution on three separate fronts that all still carry meaningful risk. Anyone that is buying or holding Rocket Lab at $120 plus per share owes themselves an honest accounting of what could go wrong.

Neutron Slippage

The most obvious risk is that Neutron slips again. The rocket was originally targeted for a 2024 launch that moved to 2025. It then moved to Q1 2026 after a stage one propellant tank ruptured during the hydrostatic test in January 2026. The first launch is now expected no earlier than the last quarter of 2026, with some analysts arguing that even that timeline looks optimistic.

Neutron development is not cheap. Spice, the Rocket Lab CFO, disclosed on the Q3 2025 earnings call that the company will have spent approximately $360 million on Neutron development through the end of 2025, with workforce costs running about $15 million per quarter. The original development estimate was $250 million to $300 million. That overrun is meaningful for a company that is not yet profitable.

Every quarter that Neutron slips is a quarter where Rocket Lab burns development cash without booking the launch revenue that justifies the investment. It is also a quarter where the NSSL lane 1 onramp gets pushed, where commercial Neutron manifests back up, and where the multiple compression risk increases. If Neutron does not fly until 2027, the bull case has to absorb a year of additional cash burn against a flat revenue ramp on the launch side.

Reusability is hard

SpaceX makes it look easy but the reality is that reusability is hard. Only two companies have ever landed and re-flown an orbital-class booster: SpaceX and Blue Origin. As SpaceX took years and many failures to make Falcon 9 reuse reliable, Blue Origin’s New Glenn has flown but is still early in its reuse program. Reusability is not a checkbox. It’s an engineering capability that takes dozens of flights to mature and it is part of the unit economics that justify Neutron’s $50 million price point.

If Neutron’s first stage proves harder to recover and refurbish than expected, if methalox cleanliness advantage is smaller than expected, if the canard and landing leg system has stability issues, if turnaround times stretch to months rather than weeks, then the economics of Neutron quickly deteriorate. A Neutron business case is heavily leveraged to reuse. Expendable Neutron is a much harder sell against the mature and reusable Falcon 9.

Scarcity Premium Can Evaporate

A lot of what is driving Rocket Lab’s premium valuation and SpaceX is scarcity. Rocket Lab is considered the only functional Western alternative to SpaceX and that scarcity justifies multiples that would not apply to a normal industrial hardware business.

And scarcity premiums are real but they are also very fragile. They depend on a competitive landscape being static and space is not static.

There’s Blue Origin’s New Glenn that flew successfully in 2025. It is ramping production. There’s Stoke’s Nova vehicle, targeting full reusability, with an architecture that, if it works, has better unit economics than Neutron. Relativity’s Terran R is in development. Firefly has an MLV in development with Northrop Grumman. ULA has the Vulcan, which is now operational. None of these are guaranteed to succeed but the field of medium-lift competitors is meaningfully larger today than it was when the market re-rated Rocket Lab.

If even two of these programs reach operational cadence over the next three years, Rocket Lab is no longer the only functional Western alternative to SpaceX. It ends up being one of several. At that point the scarcity premium would compress and Rocket Lab gets valued like a normal aerospace hardware business with a strong space systems franchise, which is real and a good business. It likely does not stay valued at 25x forward revenue.

The Verdict

Rocket Lab today is a different company than it was when I first covered it in 2024. A 3,000% return for investors reflects real operational achievement, record revenue, record backlog, the only functional Western alternative to SpaceX in development on Neutron, and a vertical integration strategy that has executed on seven acquisitions in five years and is now closing the final gaps in the stack.

At the same time, the valuation has run ahead of fundamentals in ways that require flawless execution to justify:

• Neutron has to fly

• re-use has to work

• scarcity premium has to hold against a growing field of competitors

• and the SpaceX IPO has to land well for the sector

Any one of those breaking lowers the multiple. Two of them breaking would compress it significantly.

The honest framing is that Rocket Lab today is no longer the asymmetric setup it was at $4, $10, or even $30 a share. The risk/reward has changed. The bull case is intact and arguably stronger than it has ever been, but it’s mostly priced in. The bear case is real but requires specific catalysts to manifest. The base case that Rocket Lab is a strong company executing well and a stretched valuation supports the current price. It does not necessarily support significant further multiple expansion from here.

This is the kind of company where the next 12 months matter much more than the previous 12. Neutron’s first flight, the Q2 and Q3 earnings prints, and the Golden Dome program flow will tell us whether the $120+ per share is a floor or a ceiling. Until then, every Rocket Lab holder is being asked the same question: Do you believe the execution risk is worth the price you are paying for the optionality?
