  $AXTI secured $100m from Northland for capex expansion, deferred FCF from $5m of contracted revenue from 2024 or early 2025 does not make a material difference. Stock runup was multifaceted: -> Recognition that InP substrates would bottleneck the AI industry deployment with photonics -> Recognition that InP substrate production was a duopoly (Sumitomo, $AXTI), with some smaller players like JX ->Recognition that InP feedstock was another bottleneck for the InP substrate producers ( $AXTI, Vital) with some smaller players like $DOWA. -> Supply shortage notice from earnings reports like $COHR -> Recognition that Western hypescalers are paying markups on top of SMM prices ~Dec 24th -> Recognition that AXT effectively became a monopoly after China's export controls on Japan 2 days ago (which would limit substrate production at scale from AXT's major competitor). Est 3-6 months inventory. 7n prices have hit ATHs, $AXTI owns the mines all the way to substrate production so many price increases and bifurcation in premiums between western hyperscalers + SMM would increase their bottom line. I personally don't consider contracted backlog and 1 quarter deferred contracted revenue all the way back from 2024 or early 2025 to be material before the entire supply chokepoint started. But to each their own interpretation.

  Just to give some perspective: There's two different bottlenecks. $AXTI sits in the middle of two. InP Feedstock - Duopoly (Vital, $AXTI with China controlling ~78%-80% of supply). Companies like $DOWA produce extremely low amounts relatively. InP Substrates - Monopoly ( $AXTI ). Formerly it was a duopoly ( $AXTI, Sumitomo Electric) with 60-70% of InP substrate production. With misc Japanese companies like JX contributing much tinier amounts. However this changed with export controls 2 days ago restricting feedstock and critical material supply to Sumitomo and Japanese companies that produce InP substrates. They have inventory, but with the export controls continuing, they will lack the materials to produce substrates at scale and $AXTI becomes the monopoly in 3-6 months, hence the framing. This is not a quantity game. This is game theory on price squeezes based on limited materials. $AXTI owns the mineral mines all the way to refining -> substrate production and the supply chain + cost structure. This translates into margins. You were looking at few hundred million TAM that could now inflate to $10B+ just due to pure necessary required for $GOOGL TPUs, $MSFT maia, $NVDA, $META, and so no AI buildout with photonics. This $1B company controls two different bottleneck for the AI buildout. I'm buying into the bottleneck like what happened at the start with HBM with $MU and $SNDK, I'm not trying to convince you to as well, just sharing my thesis.

  The InP substrate shortage and "Spread" Arbitrage - $AXTI Market research is showing InP and optical components to become analogous to the HBM shortage and price craze. The initial bottleneck was caused by $NVDA monopolizing of the production capacity of EML from $COHR to $LITE (TrendForce). Here's the breakdown: $NVDA has reportedly engaged in strategic capacity reservations for EML laser chips, pushing lead times for these specific components beyond 2027. By booking out the finished goods capacity of IDMs like $LITE and $COHR (who are constrained by InP), Nvidia has effectively removed the capacity for optical engines. The "Second Order effect": As a result, many hyperscalers have likely delayed their roadmaps/ramp from $MSFT to $AMZN and are looking for capacity. Optical makers have also scrambled for alternative sources. Since the primary IDMs are booked, hyperscalers are moving upstream to secure wafers, substrate, and feedstock capacity directly, creating a effect that is amplifying demand at the materials level. Both 6N and 7N Indium are at all time highs on the Shanghai Metal Markets; prices sit higher on Western markets, representing a price bifurcation between China and Western markets. 6N for example sits ~$412.83-$425.46 per kg. 6N Western prices are ~$668.00 (Jan 1st, source: Indium Corporation at 5-9 kg quantities), over 50%+ premium. (Spot direct negotiations to hyperscalers would likely have different prices). Premiums for 7N would likely higher margin, with substrates commanding the most premium (not public data, but some estimates go into triple digit premiums) However, the bottleneck has now migrated upstream to substrate itself (and third order effect, feedstock) to secure capacity. $AXTI perhaps plays one of the most critical roles and unique roles as "40% of the InP supply chain" ( $AXTI CEO ER quote) in the InP bottleneck: Low costs: AXTI's factory is in Beijing. They source materials (own 10+ materials suppliers) and refine them themselves into finish substrates. Sell High: They sell finished InP substrates to the global market, where prices are inflated by the shortage and the Western Indium price. Arbitrage: As long as AXTI continues their export permits, they capture the massive spread between low Chinese manufacturing costs and high global selling prices. This is compared to Western companies that are largely affected by upstream material costs and Western premiums. As a result $AXTI, margins next quarter should expand rapidly on top of their production capacity funded by the $100m share sale injection by Northland. This is implicated from reports from late December reports from Asian Metal, indicating that Chinese suppliers explicitly "raised offering prices" for exports to the US: December 19, 2025: Asian Metal reported that "Indium ingot suppliers raise offering prices in United States," marking the beginning of the specific divergence in Western pricing. December 24, 2025: They subsequently reported that "Suppliers of indium ingot raise quotes in China," confirming that the pricing pressure had solidified across both domestic and export channels by the end of the week. This stems from capacity monopolization by hyperscalers, extended lead times, and a decoupling of "AI" material pricing from commodity baselines. The conditions for a "Massive Price Increase" for InP substrates are not just present, they are active. Throughout 2026, both the price of InP substrates, and by one-hop, the commodity price of Indium would likely see a rapid surge as hyperscalers go upstream to secure demand. The company that benefits both ways from the a possible parabolic rally in InP substrate + InP feedstock prices would be $AXTI, presenting an asymmetrical upside at $16, ~$850M MC. However, the risks are present as they're heavily reliant on export permits and US-China trade relations. TLDR, AXT: 1. Sits in the center of both InP substrate and InP feedstock bottlenecks 2. Benefits from margin arbitrage and substrate price surges between China production and US hyperscaler premiums during allocation battles. 3. Controls a major a major percentage of the world's merchant output for substrates required for the Western hyperscaler AI buildout. Hyperscalers saw Nvidia monopolized EML capacity and are likely looking at companies like $AXTI, Sumitomo or feedstock (Vital, $AXTI, $DOWA) to secure their roadmaps now. AXT is one of the most interesting companies at $850m given it controls the critical bottleneck to the hyperscaler AI buildout and captures both the InP substrate price surge + margin arbitrage opportunities.

  When I made my WSB post, I'm half joking about $AXTI. But not about the extreme bottleneck and InP supply shock. This is a call on critical materials game theory. If we see many historically at bottlenecks: 1. Dysprosium: ~2,300% increase (~$100/kg -> $2400/kg 2010-11) 2. Neon Gas: ~1000%-2,000% increase (2022) 3. Rhodium: ~$3,000/oz -> ~$29,000/oz (~860%) The current Indium spike compared to others? 89% : (~$440 / kg -> ~$832 / kg). Critical materials used for semiconductors like Neon Gas (semi-grade lithography lasers), spiked over 2000% because chipmakers like Intel and Samsung had stockpiled during Ukraine conflicts. They absorbed the cost because neon is a small fraction of the chip's value. Like Neon, InP is a critical "enabler" material. The cost of the wafer is small relative to the cost of the AI cluster ($100 wafer vs $30,000 GPU). Hyperscalers would happily absorb huge price increases rather than delay deployment. We haven't seen that yet with InP, but we likely will. Traditional analysts and many AI Models do not understand how to model critical bottlenecks because there's not many examples in history where an extremely cheap commodity like InP with few hundred million TAM suddenly became the most critical material for the multi-trillion+ AI buildout. Currently, hyperscalers likely placed backlogs on downstream providers Coherent / $LITE, but likely didn't realize that laser production and capacity are backlogged because of materials shortage upstream. There is a supply storage both for InP substrates ( $AXTI + Sumitomo + JX production) as well as the Indium Phosphide feedstock ( $AXTI, Vital, $DOWA) where demand exceeds supply by multiple factors. $NVDA originally contributed to the supply shortage by locking in a large percent of capacity of EML. But shortage is already pre-hyperscaler ramp, where majority of the demand will come in late 2026 into 2027 when Trainium or Maia show up. But how do you get around original chokepoint and securing your AI deployment? Buying out substrate capacity directly from ( $AXTI, Sumitomo) or going one step lower and buying InP feedstock and passing them to substrate producers so Google's TPU program doesn't stall. And similar to how other critical materials were needed for lithography lasers. Indium Phopshide and InP substates are even more critical to the entire AI buildout: 1. Nvidia: InfiniBand / NVLink (optical - 800G/1.6T EML Transceivers) - Extreme dependency on InP 2. Google: Jupiter / Apollo (optical - OCS), Extreme dependency 3. Microsoft: Azure Maia: High (800G DR4/FR4) 4. Meta: F16 / Artemis (800G) High and this is not considering other Mag7 companies like $AMZN or other companies scaling out ASICs with photonics. Currently, analysts are modeling InP companies based on TAM. For example, the total InP Wafer Market from 2024 is $183M – $205M Straits Research, Mordor Intelligence (2024) - 6-inch (150mm) Segment TAM: $65m - Projected Total InP TAM (2032): $580M – $700M Now looking at TAM for Laser-Grade Indium Phosphide Feedstock: - Polycrystalline InP Feedstock TAM: ~$300 Million - High-Purity Indium (6N/7N) Only: ~$400 Million Substrate Data: Mordor Intelligence (InP Wafer Market 2025-2030) and Straits Research. Feedstock Data: Market Report Analytics (Indium Phosphide Polycrystalline Industry Analysis 2025). This was an extremely cheap telecom product and now it's one of the most precious materials in the entire supply chain. Increasing prices 3000% would only be low single digits of BOM value to $GOOGL TPU deployments or $MSFT MAIA deployments. And the project Microsoft ramp in 2027 alone would take up double digits of all InP capacity. Like Intel or semis back in 2022, hyperscalers will likely buy insurance directly with InP substrates + InP, similar to how semis stockpiled Neon Gas. If the "TAM" really was a few hundred million, but every single hyperscaler would face deployment delays if they don't secure this material. Then this becomes a game theory bidding war. In a $20B TPU deployment is stalled because of a $100 substrate, a hyperscaler would easily pay $10,000 (100 times current prices) for it without hesitation. That's why when you look at InP substrate companies and see $50m backlog (from 2024), that same $50m worth of capacity for future ones could be valued at $500m, $5B or more in an extreme scenario. This is a "tail-risk" investment, extremely reward if hyperscalers get bottlenecked by this material, but not without significant geopolitical risk and dilution. I don't know what's going to happen, but I do expect there to be an immense bottleneck in 2026 both in InP substrates and InP feedstock. So, if companies like $AXTI owns 40% of the entire InP supply chain (source: AXT CEO) and is valued at $700m, what value would you place on it?

  $COHR is amazing and probably the leading US company for InP substrate prod with their new 6in wafer fab. Two nuances: 1. Their production is nowhere close to the scale needed for hyperscalers that $AXTI and Sumitomo currently outputs 2. They are bottlenecked by upstream InP feedstock needed to grow crystals (owned by Vital, $DOWA, and $AXTI (captive)). CEO said in their ER that their capacity was maxed out and limited by InP lasers (and by 1 hop InP needed to produce them) My thought process is that instead of placing more order backlogs with $COHR, hyperscalers would go upstream. They would directly source 6n-7n from Vital, $DOWA, $AXTI and others that control InP, and give them to fabs like Sumitomo / $COHR or one level higher, buy out stock of InP substrates -> hand to $LITE as insurance. That being said a lot of money will likely be poured into Western supply chains but their capacity is nowhere enough since they're still bottlenecked upstream.

  "Bottleneck within a Bottleneck": Indium Phosphide $AXTI | $SMTOY is a duopoly. They control 60%+ of the world's InP substrates as the bottleneck of the AI buildout. What's even more alarming? This is dependent on: Indium Phosphide. InP is a Monopoly. 78% control by $AXTI / China. Here's the bottleneck within a bottleneck: The InP substrates is already a duopoly between Japanese and Chinese entities. However, upstream production of laser-grade feedstock required by companies like Sumitomo is dominated by $AXTI (again) and Chinese companies. Here's the major issue: The AI industry is extremely reliant on photonics to scale. Whether, transceivers are "InP-based" or "Silicon-based" the photon source remains: Indium Phosphide. As AI clusters move from 10,000 to 100,000+ GPUs, the "copper bottleneck" is forcing a total shift to optical interconnects. This makes InP more critical to AI scaling than almost any other single material. On top of that, laser-grade feedstock must be at least 6N (99.9999%) pure. Even trace amounts of impurities (Silicon, Sulfur, Zinc), cannot be used like they do in other segments like LED. And most research probably confuses laser-grade feedstock with regular InP outputs. Sumitomo is arguably the most famous name in the InP substrate market. They hold a massive market share in the high-end laser substrate segment. Yet trade data suggest they are increasingly reliant on external feedstock for Indium Phosphide from companies like $DOWA and from China. (They're likely still included in feedstock ownership lists bc of captive recycling and reserves) So if the entire Western AI buildout feels safe regarding a Japanese company as a duopoly, think again. The source of the bottleneck is bottlenecked by Chinese suppliers like $AXTI and Chinese companies. If we look at production there's are estimates from deep research breakdown of estimate controls: Vital Materials - 35% (Merchant) - Vital acquired Fanya Metal Exchange inventory (3,600 tonnes of Indium) in 2020 gave them large control over the global Indium market. They have leveraged this to become the largest producer of InP polycrystal. Dominant cost leader; controls raw Indium supply (Fanya stocks). $AXTI - 25% (Beijing Tongmei Xtal Technology) - Primarily Captive. Most of their polycrystal production is consumed by their own crystal growth furnaces to make wafers. However, they also sell raw materials and compounds to the merchant market, making them a hybrid player. They're the only company in the world that goes from mines, refineries -> InP substrate output, which is an absolutely crazy bottleneck given they own both the raw materials into InP substrate controls. Feeds own wafer production; key non-Japan source. Zhuzhou Keneng New Material - 18% - Keneng has achieved "mass production of polycrystalline indium phosphide" and possesses "highly integrated automatic polycrystalline production capacity". They are a key recipient of China's export quotas for Indium. Pure-play synthesis specialist; major exporter. Then Outside: $DOWA - 12% - The biggest supplier out of any Western company (yeah Japanese). Deep roots in mining (Akita Zinc), so they're the leading supplier of high-purity metal organics and compounds. The "source" for Japan Inc. (Sumitomo, JX) Wafer Technology Ltd - 5% - A subsidiary of IQE plc. Critical strategic asset for NATO-aligned supply chains that require non-Chinese feedstock, even though they're going through asset liquidations right now. InPACT (France) - 3% - InPACT states they produce polycrystalline ingots via Horizontal Gradient Freeze (HGF) using high-pressure synthesis so they meet requirements from (Nokia, Ericsson) and some European defense sectors. Rest of World - 2% This includes major substrate makers (Coherent, Sumitomo), small-scale research production, and emerging players in Korea or Taiwan who are attempting to break the monopoly. The reality is that 78% of the global capacity for laser-grade InP feedstock is located in China. The demand for optical components already exceeds supply/production by multiple factors. This is pre-ramp too. The entire AI buildout is bottlenecked by two companies. But 1/4th of the materials comes from: $AXTI. And ~1/3rd of InP Substrate outputs again comes from laser-grade feedstock. The entire AI buildout is dependent on some random $700m company that serves as both the bottleneck of a bottleneck and the bottleneck. It's both national security issue to scale up InP production both for substrate and laser-grade feedstock.

  Sumitomo is subject to hikes in InP prices though if $GOOGL goes direct to $DOWA or others for feedstock. $AXTI owns the whole supply chain, and a huge portion of laser grade inp. But downside is obviously anuke from China exports. Sumitomo Electric is huge though so you’re not exactly getting the most direct exposure.

  Uhh, from my own personal research so far, to cover all grounds I’ve liked: 1. $AXTI at the very bottom of the entire supply chain + 1/3rd of InP substrates 1/4th of InP. Completely unheard of that AI supply chain is tethered to this $700m stock. 2. $DOWA + Sumitomo Electric for Western Hedge on substrate + materials. 3. $AAOI, $LITE for hyperscaler chips, one for $AMZN/ $MSFT, the other for everything but more levered to $TPU 4. $MRVL + $AVGO I think that’s kind of all you need to capture photonics BOM value + InP supply shock. There’s some other interesting ones like Landmark Opto that I’m looking at now. $POET didn’t quite make that list and you’d be getting exposure through $MRVL anyway, unless there’s something I missed
