• 過去最高となった1億200万ドルの営業キャッシュフローが、在庫投資や株主還元を支えました。Rambusは1億ドルの加速型自社株買い（ASR）を含む1億3,500万ドルの自社株買いを実施しました。
• 経営陣は第4四半期の売上高見通しを2億2,700万ドル〜2億3,300万ドル、製品売上高を1億2,700万ドル〜1億3,300万ドルと設定しました。中間値に基づくと、製品売上高は前年同期比34%増、前四半期比14%増となる見込みです。
• 経営陣は、サプライヤーのリードタイムが長くなり供給不足が続くと予想されるものの、2027年に向けて需要は一段と強まっていると述べています。

主要財務実績

事業および業績の動向

Rambusは、製品売上高が過去最高を記録した主な要因として、DDR5レジスタード・クロック・ドライバー（RCD）製品群の堅調な推移を挙げています。DDR5-9600に対応する第6世代RCDは、現在顧客向けに広範なサンプル出荷を行っています。コンパニオンチップも前四半期比で成長を継続した一方、MRDM関連の初期出荷は小規模にとどまり、認証評価や量産前試作を中心とした展開となりました。

経営陣によると、メモリ速度の向上とサーバーアーキテクチャの異種混在化（ヘテロジニアス化）が進むことで、タイミング、電力、セキュリティの管理機能に対する追加需要が生じています。同社はこれにより、メモリモジュール当たりの搭載チップ価値（チップコンテンツ）が時間の経過とともに向上すると見込んでいます。また、DDRベースのサーバーが8メモリチャネルから12または16チャネルへ拡張されることも、モジュール需要の拡大を後押しする可能性があります。

Rambusは、LPDDR6サーバーメモリ向けのPMIC（電源管理IC）をラインナップに加え、電源管理のロードマップを拡張しました。電力管理の複雑さが増すことから、経営陣は新世代製品が従来のLPDDRベースのソリューションよりも高い単価（単体価値）をもたらすと期待しています。市場への本格投入は2028年頃と予想されていますが、経営陣はこれをAIインフラストラクチャにおけるニッチな領域として位置付けています。

シリコンIP事業では、次世代HBM、PCIeコントローラおよびスイッチIP、ハードウェアセキュリティの分野でデザインウィン（採用決定）を獲得しました。高度なメモリインターフェース、高速接続性、ハードウェアベースのセキュリティに対する需要の高まりを背景に、カスタム半導体開発企業やハイパースケーラーとの交渉・協業機会が増加していると経営陣は述べています。

同社はシリコンIP事業を年間売上規模約1億3,000万ドル、成長率10%〜15%のビジネスと説明しています。経営陣によると、2026年の業績はその予想レンジの上限に近い水準で推移しているとのことです。

Rambusはまた、将来の製品増産を支え、顧客にさらなる供給の安心感を提供するため、第3四半期中に在庫を1,200万ドル増加させました。経営陣は第4四半期にも同様の在庫増加を見込んでいます。

経営陣による業績予想

中間値に基づくと、第4四半期の製品売上高は前年同期比34%増、前四半期比14%増となる見通しです。中間値のNon-GAAP EPSである0.88ドルは、前年同期比30%増、前四半期比5%増の成長を示します。

経営陣によると、第4四半期見通しの中間値は、2025年度比の2026年度通期で約18%の売上成長、24%の製品売上成長、および24%のNon-GAAP EPS成長を意味するとのことです。

Rambusは、第4四半期の製品売上総利益率が近期の目標範囲である60%〜63%の範囲内にとどまり、前四半期比でわずかに改善する可能性があると見込んでいます。経営陣は、2026年度通期の製品売上総利益率がその範囲の中間値付近に着地すると予想しています。

同社は、製品ロードマップや成長機会への投資を維持しながら、引き続き長期的にフリーキャッシュフローの40%〜50%を株主に還元する計画です。

リスクと注目点

• 半導体サプライチェーンの逼迫に伴い、サプライヤーのリードタイムが長期化しています。経営陣は、これが第3四半期の業績に影響を与えず、第4四半期の業績予想にも影響しないと見込んでいますが、2027年を通じて供給逼迫が続く可能性が高いとしています。
• サプライチェーンにおける投入コストの上昇が製品売上総利益率の圧迫要因となっており、近期の目標範囲である60%〜63%の下限に近い水準へ押し下げています。Rambusは社内のコスト削減により、その影響の一部を相殺しています。
• 経営陣は、プラットフォームの採用時期が分散していることや、同技術が普及サイクルの初期段階にあることから、MRDMの成長ペースは通常のRCD世代の交代よりも緩やかになると予想しています。
• 顧客による受注確定（バックログ）の早期化が進んでおり、Rambusの業績見通しの視認性（ビジビリティ）が向上しています。しかし、ダウンストリーム（末端）顧客が在庫を積み増しているかどうかを判断するのは困難であると経営陣は述べています。
• LPDDRベースのサーバーメモリは、従来のDDR構成を置き換えるのではなく補完するものと見込まれていますが、経営陣は市場全体の中では引き続き小規模な割合にとどまると予想しています。

アナリスト質疑応答の要点

製品売上高の成長加速： 経営陣によると、第4四半期の成長見通しは主に新世代RCDとコンパニオンチップの拡大が牽引しています。MRDM関連の売上高は引き続き小規模にとどまっています。

2027年の需要： Rambusは2027年に向けて需要の拡大と受注残の視認性改善を見込んでいます。経営陣は依然として上半期と下半期の間で多少の季節性を見込んでおり、2027年の定量的な業績予想は開示していません。

シリコンIPの拡大： 同社は、特にハイパースケーラーやカスタム半導体開発企業のアーキテクチャ計画への初期段階からの関与を深めています。経営陣は、これによりシリコンIPのポートフォリオと将来のチップ製品の両方に活用できる知見が得られると述べています。

供給計画： Rambusは自身のバランスシートを活用して在庫を構築し、想定される需要に対応するためにサプライヤーと密接に連携しています。川上サプライヤーのリードタイムは長期化しているものの、顧客向けリードタイムは増加していません。

メモリアーキテクチャの構成割合： 経営陣は、市場成長の大部分を従来のDDRメモリを使用する標準的なCPUサーバーが占め、LPDDRベースのソリューションは特に電力効率が重視される補完的な用途に対応すると予想しています。

Luc Seraphin

Thank you, Sumeet. Good afternoon, everyone, and thank you for joining us. In Q3, we delivered a truly exceptional quarter. Revenue and non-GAAP earnings both reached new record highs and exceeded the top end of our guidance ranges. Strong customer demand, fueled record product revenue and cash from operations and we expect an even stronger product performance in Q4. We introduced new chip and silicon IP products that extend our leadership in data center and AI infrastructure.

In addition, as complexity and pace accelerate in semiconductor development for AI, we are also investing in the tools and infrastructure that will keep us on the leading edge of technology. As such, we engaged with a fellow pioneer in the ecosystem and announced an exciting new partnership that propels us into the age of AI agent-driven chip and IP design.

As we continue to invest in our future, we are also pleased to have completed a $100 million accelerated share repurchase. This demonstrates the strength of our business model and our ability to return value to our stockholders while advancing our product road map to drive long-term growth. Taken together, the results and progress we delivered this quarter reflect the strength and long-term resilience of a strategy we have pursued over many years, investing in technology leadership, anticipating the key trends transforming the data center and positioning the company to capture the opportunities those trends create.

Our strategy is producing strong results today while at the same time, laying the foundation for future growth. As we outlined over previous quarters, AI continues to create strong tailwinds for Rambus across our businesses. As Frontier AI training continues to advance, and inference scales across a growing range of applications, customers require increasingly sophisticated memory and infrastructure architectures to move, manage and secure growing volumes of data. Agentic-AI is accelerating this trend as deployments evolve towards more distributed and heterogeneous architectures that require greater coordination across systems.

At the same time, orchestration of always-on workloads puts greater demands on the CPU, lifting CPU to GPU ratios and driving requirements for more main memory bandwidth and capacity across the data center. The latest agentic implementations amplify this need even further by assigning dedicated compute and memory resources to individual users or agents. All this creates accelerating demand for Rambus products and IP throughout the memory subsystem and across the broader infrastructure stack, while we continue to invest in the fundamental R&D and product road map required to address the ever-growing demand of memory management efficiency in the long run.

Now let me turn to the quarterly results, starting with products. We delivered a new all-time high in quarterly product revenue, reaching approximately $114 million, up 15% sequentially and 22% year-over-year. Our leadership in DDR5 RCDs and growing adoption of new generation products fueled our record results. We are seeing strong demand across multiple generations of our RCDs supporting our outlook for another record quarter of product revenue in Q4, which we expect to grow more than 30% year-over-year.

Looking ahead, we have a strong pipeline of products aligned with upcoming platform ramps positioning us well for next generation of server platforms. As part of that pipeline, we are pleased to share that our sixth generation RCD announced early in Q3 which supports DDR5 9600 is now sampling broadly with customers and is being very well received. We continue to execute successfully on our road map, recently expanding our product portfolio with an industry-leading PMIC for the upcoming LPDDR 6 so CAMI.

Earlier this year, we introduced our first SoCaM2-chipset that supports LPDDR5. This new PMIC solution extends our server memory product road map to LPDDR6 and reinforces our leadership in advanced server memory power management. It was developed in close collaboration with customers and ecosystem partners to enhance memory subsystem power efficiency and help scale tokens per watt for AI workloads.

We identified early on that power management would be critical to the success of AI deployments and have been investing in this area for many years. We are proud of our progress and continued leadership in this space. We have consistently said that as memory speeds increase and server architectures become more sophisticated and heterogeneous, the memory subsystem will require additional intelligence, power management and control functionality.

Our road map is designed to address this evolution across both DDR and LPDDR based memory with timing management, power management and security management creating opportunities for Rambus to participate in increasing module chip content over time.

In addition, DDR based server platforms are expanding from 8 memory channels to 12 to 16 channels, increasing the maximum available memory bandwidth and capacity. This raises the number of modules supported in the server and amplifies demand as platforms progress. Today, Rambus offers complete chipsets across all major industry standard DDR5 and LPDDR server memory module architectures. This broad portfolio positions us well for future server platforms and allows customers to leverage Rambus solutions across a growing range of memory architectures and deployment models.

Looking ahead, we believe we are exceptionally well positioned for future server generations and for the continued expansion of memory-intensive AI infrastructure.

Turning now to silicon IP. We delivered a very strong quarter with key design wins across our Silicon IP portfolio. The strength of those wins, combined with expanding strategic engagement across the industry, including custom silicon makers and hyperscalers reinforces our confidence in the long-term growth opportunity for the Silicon IP business and for Rambus. One of the defining characteristics of today's market is the rapid growth of custom silicon. The expansion of AI is fueling a new wave of custom silicon development, hyperscalers, AI infrastructure providers and emerging semiconductor companies are designing increasingly differentiated architectures and tailored silicon optimized for their own environments.

These systems depend on advanced memory technologies, high-speed interconnects and trusted security creating significant opportunities for Rambus Silicon IP. During the quarter, we drove increasing ecosystem engagement and new Tier 1 design wins for next-generation HBM supported by our deep architectural engagements ahead of standards being finalized. We continue to see increasing interest in PCIe controller and switch IP for scale up and scale out connectivity solutions. as customers seek higher levels of performance and efficiency across rapidly expanding AI infrastructure.

The importance of bleeding-edge IP continues to increase as customers pursue differentiated performance, power efficiency and time-to-market advantages. As a result, we are engaging earlier in the architectural planning cycle with both our customers as well as our customers' customers and participating in a broader set of strategic programs.

Leading edge memory and connectivity are fundamental to performance and as AI infrastructure scales and becomes more heterogeneous, hardware-based security foundation is becoming fundamental. Agentic-AI relies on distributed computing architectures that execute workloads across multiple systems, which increases the available attack surface for adversaries, a growing concern in the current environment.

As a pioneer and longtime leader in hardware-based security, Rambus IP solutions address that risk by providing a trusted foundation for the entire system and enhancing protection for valuable data and infrastructure. Building on our industry-leading security offerings, we recently added a new route of trust solution, designed specifically for AI and data center deployments that supports the Elektra specification.

Elektra was developed by key leading technology companies to establish a common hardware security foundation for data center class SoCs and reflects the growing recognition that hardware-based security is essential for next-generation infrastructure. Looking across both chips and silicon IP. We will continue to drive solutions that address the long-term foundation memory performance, high-speed connectivity and robust security demands of AI infrastructure.

At the same time, we are harnessing AI to advance the underlying tools and development infrastructure that enable us to move faster, extend our leadership and scale the business more effectively. As I mentioned at the beginning of the call, we recently announced a strategic investment and collaboration with chip agents, a fellow industry pioneer and leader in Agentic AI design platforms.

We see great opportunities to leverage the cheap agents AI-native design flows to accelerate our road map by speeding the pace of our chip and IP development, improving design quality and enhancing and generating productivity across our organization. We believe this collaboration further strengthens our competitive position, both for products and for IP and reinforces Rambus leadership role in next-generation of AI data center infrastructure.

In summary, the company delivered an exceptional third quarter, and we expect an even stronger Q4 as we continue to capitalize on the growing demand from AI. We achieved record revenue and earnings while expanding our chip and IP offerings. And at the same time, we are investing in our development infrastructure to address the growing opportunities ahead. These results and decisions reflect the strength of our strategy and the continued alignment between Rambus technology and the most important trends shaping AI and data center infrastructure.

We are executing well and more importantly, we are continuing to invest for the future and build on a strong foundation of technology leadership and customer partnerships. We are confident in our trajectory, our road map and our ability to drive continued profitable growth in 2027 and beyond.

As always, I want to thank our customers, partners and employees for their continued trust and support. And with that, I'll turn the call over to Sumeet. Sumeet?

Sumeet Gagneja

Thank you, Luc, and good afternoon, everyone. We delivered an outstanding third quarter, achieving record revenue and earnings and record cash flow from operations. These results reflect the strength of our business model, growing demand for our products and technologies and disciplined execution across the company. Consistent with our balanced capital allocation strategy, we completed a $100 million accelerated share repurchase program during the quarter.

The transaction demonstrates our confidence in the business and our commitment to returning capital to shareholders while preserving the flexibility to invest in the growth. Looking ahead, we believe Rambus is well positioned to capitalize on the secular growth in AI infrastructure, data centers and advanced computing through the strength of our product and technology portfolio.

With that, let me review our third quarter financial results. Third quarter revenue was $218 million, driven by strong product and contract revenue. This represents growth of 22% year-over-year and 5% sequentially. Product revenue was $114 million which is up 22% year-over-year and up 15% sequentially. Royalties revenue was $77 million. Contract and other revenue was $27 million, up 35% year-over-year and 13% sequentially. Contract and other revenue consists primarily of silicon IP, as a reminder, only a portion of our silicon IP revenues reflected in contracts and other revenue and the remaining portion is reported in royalties revenue.

Total non-GAAP operating costs including cost of goods sold for the quarter were $116 million. Operating expenses were $70 million, down sequentially due to slightly lower R&D and SG&A expenses. Interest and other income for the quarter was $7 million. Using non-GAAP tax rate at 16%, non-GAAP net income for the quarter was $91.7 million, resulting in Q3 non-GAAP earnings per share of $0.84, which is up 35% year-over-year and up 10% sequentially.

Now let me turn to the balance sheet details. We ended the third quarter with cash, cash equivalents and marketable securities of $777 million, down $48 million from Q2. Record cash flow from operations of $102 million were offset by $135 million of share repurchases, including the $100 million accelerated share repurchase program. Capital allocation remains a key priority for us. We intend to continue investing in the business while returning 40% to 50% of free cash flows to shareholders over time, supported by our strong balance sheet and continued cash generation.

Our capital allocation approach reflects our focus on driving shareholder value while investing in our growth and pursue long-term opportunities ahead. We also leveraged the strength of our balance sheet to increase inventory by $12 million during the quarter, positioning us to support future product ramps and provide customers with greater supply assurance.

Now let me turn to our non-GAAP outlook for the fourth quarter. As a reminder, the forward-looking guidance reflects our best estimates at this time. and our actual results could differ materially from what I'm about to review. We expect fourth quarter revenue to be between $227 million and $233 million. Product revenue is expected to be between $127 million and $133 million. At the midpoint of the guidance, it is an increase of 34% year-over-year, an increase of 14% sequentially. Royalties revenue is expected to be between $68 million and $74 million and contract and other revenue is expected to be between $26 million and $32 million.

We expect Q4 non-GAAP total operating costs which include cost of sales to be between $124 million and $120 million. We expect Q4 capital expenditures to be approximately $8 million. Non-GAAP operating profit for the fourth quarter is expected to be between a profit of $103 million and $113 million. We expect fourth quarter interest and other income to be approximately $6.5 million. Assuming a non-GAAP tax rate of 16% and $109 million diluted shares outstanding, we expect fourth quarter non-GAAP earnings per share to be in the range from $0.84 to $0.92.

At the midpoint of the guidance, this represents growth of 30% year-over-year and 5% sequentially. Overall, we are very pleased with our third quarter performance. Our record revenue, earnings and cash flow from operations demonstrate the breadth of our product and technology portfolio, the diversity of our revenue streams and the disciplined execution of our teams. The midpoint of our fourth quarter guidance implies that 2026 revenue will grow approximately 18% over 2025, including product revenue growth of approximately 24%.

With our continued focus on driving growth and operating efficiency, we expect non-GAAP earnings per share to grow approximately 24% over 2025. We remain focused on executing our strategy and capturing the opportunities created by AI infrastructure, data center and advanced computing markets. We are committed to translating these opportunities into sustainable growth, strong cash generation and long-term shareholder value.

With that, I'll turn the call back to the operator for Q&A. Operator, could we have our first question, please.

Operator

[Operator Instructions] Your first question comes from the line of Kevin Garrigan with Jefferies.

質疑応答

Kevin Garrigan

Luc, so Q3 product revenue growth was 22% year-over-year. the Q4 midpoint implies about 34%. I know you talked about strong growth across RCD generations. But can you give us a sense of how much growth is coming from other areas like companion chip ramps or any initial MRDM shipments?

Luc Seraphin

Thanks, Kevin. Yes, we're really pleased with the results for Q3 and the growth for Q4, 34% year-over-year. We always saw that the second half of the year would be stronger than the first half of the year. I would say it's a combination of market demand going up. and a lot of our products actually ramping into the market. The new generation of our RCDs make the bulk of that. At the beginning of the year, we said that our companionship were approximately low double-digit percentage of our product revenue and that it would grow sequentially quarter-over-quarter. We see this happening.

And margin remains very modest actually. We have shipped the margins for qual and preproduction this year. The AMD platform is starting to ramp. So it's still very modest. So we're really, really pleased with this 34% year-over-year growth based on the core, I would say, LCD and companion chip.

Kevin Garrigan

Okay. Great. And then as a follow-up, just on the MRDM opportunity. So the RCD playbook was always about being first to market and qualifying early. One of your competitors was designed for the first-generation MRDM platform. So what's different about this next generation that gives you confidence that you can take a leadership position?

Luc Seraphin

The difference with MRD is that is associated with the launch of the platform that is very different than what we have all seen for the past few years. There's only 1 platform that is supporting MRD now going into the market. We don't know what the -- what the portion of the margin is going to be compared to the standard be in that area. So it's going to be a ramp, and we're confident this ramp will happen. We still believe this is a great opportunity for us that we still size at $600 million in total.

But the rent will be shallower in our opinion, than the other generations of products, simply because all of the platforms are not ramping at the same time. This is a new technology, and our customers have to adopt this technology and go through the initial standards. There's also this thing that we see in the market of memory despecking. It's not that people decrease the number of modules, but they tend to decrease the capacity of each 1 of these modules. So we do see a growth of the number of modules in the market that explains our growth in Q4.

But we do see at the same time that each 1 of these modules tend to have lower capacity and it's due to the economics of the memory at this point in time. So between the memory economics, the stage ramp of the platforms and the introduction of new technology and supply associated with that, we see this as a great opportunity, but we see the ramp to be shallower than a standard ramp of an LCD product.

Operator

Your next question comes from the line of Gary Mobley with StoneX.

Gary Mobley

Congrats on strong execution as we navigate through the second half of the year. Clearly, the second half of the year is playing out with seasonal strength on the product side as you had been communicating throughout the year based on what seems to be a strong market environment, and your existing backlog, how would you call out the seasonality in the first half of the year, you see something a little atypical, maybe probably better than seasonal in the first half of the year? How do you see your visibility plan in the first half of the year on the product side?

Luc Seraphin

Yes. So you're correct, Gary, the second half of the year, we have this seasonal effect that is advantages to us. I would add to this, so this year that I think we're really pleased with the execution. We do see our companionship ramp in earnest, for example. There's a new generation being adopted at a higher rate than they used to be. When we look into 2027, I would say that we see demand strengthening. I think this is not going down. So we're quite optimistic for 2027. The demand is strengthening. We have a better visibility into our backlog is going into 2027.

I think we're going to continue to see some sort of seasonality between the first half and the second half in 2027. But in aggregate, we are confident with the health of the demand growth in 2027.

Gary Mobley

As my follow-up, I wanted to ask about the Silicon IP business. I think you've been communicating that this might be a $130 million annual business. I would assume that -- you're maybe trending above that. Can you confirm or give us any color on that? And then with respect to custom ASIC development, do you see an opportunity, whether it be on high-speed Seres interface IP, high-speed memory interface IP or security IP to forge a long-term development arrangement with some of the hyperscalers developing custom silicon like what we've seen with some of the other competitors in the IP space?

Luc Seraphin

Yes. So Gary, I'll start with the second question about the potential for silicon IP and then I'll ask Sumeet to answer on the revenue and the revenue growth. We are engaged more and more with the ecosystem on the silicon IP because people are building more and more complex chips that require more and more complex integration. And on the bleeding edge of technology, this is, for example, what we described in our last call with the engagement with a hyperscaler on next generation of memory.

So we see our confidence in the silicon IP keeps increasing. If you look at our product rollout, we talk about PCIE7 IPPCIE7 switch, HBM in ex generations of HBM, these dedicated security solutions for the data center. So we are engaged deeply with the ecosystem. that gives us the opportunity going forward to potentially continue to increase our portfolio, not only organically but possibly inorganically and also to partner with our customers to develop broader system.

So as part of our thinking for silicon IP, we have that notion of working more and more with our partners on the system level. By the way, the announcement we made about Agentic-AI helps to do that. the ability to have agents work with us on integrating IP in much more complex systems is actually enabled by this type of things. So we're building the infrastructure to do that. That's the direction we are going into. It's going to take us time, but that's definitely a great trend for us. I'll let Sumeet answer on the numbers, yes.

Sumeet Gagneja

Yes. Thanks, Luc. And just to add to that, Gary. So yes, so we've said our silicon IP business around $130 million, growing at 10% to 15%. But like Luc said, our confidence has been building throughout the year, and 2026 has been a great year for our silicon IP business, along with our strong momentum in the design win. So I would put it more like we're drawing more towards the higher end of that range. We have said 10% to 15%, and we continue to make progress in all aspects from memory interface and security aspects.

Operator

Your next question comes from the line of Sebastien Naji with William Blair.

Sebastien Cyrus Naji

Yes. Maybe first, I wanted to ask about the LPDDR 6 PMIC that you announced. Could you maybe give us a sense for how that increases your dollar content per module versus the SO CAM2 content that you had announced in April, I think it was 2 voltage regulators and an SPD Hub. And then when do you expect maybe some initial revenue for that product?

Luc Seraphin

Thanks, Sebastian. I would say that I'll be a bit discrete about the exact content on this so can 2 because it's not -- the final space has not been released yet. So you'd rather wait for the final spec to be released. But what I can say is that when you move from the first version of Slocan that we announced earlier this year to this new generation of SOCOM. The content is increasing. The power management is more complex. And as a result of that, the dollar content is going to increase from that first generation to that second generation.

The module performance itself is going to be much better as well, which will, I would say, trigger adoption at a higher level. But as every 1 of these Scan solutions, they provide a very good solution for these areas very high where power performance is really, really important. But this is a small portion of the market, and that's going to be continuing -- that's continued to be the case between the first version of SoCam and this will come to. SoCAM2 will hit the market probably in 2028. And the way to look at it is we see the development of the AI infrastructure as having multiple horizons for us, if you wish.

We want to make sure that we developed those solutions way ahead of the market. And when they deploy in the market, then we are present with solutions that work. This is what we've done in the past that explains, for example, our performance in Q4 this year that are based a lot on the products we developed in the past. they had little traction at the beginning, but they're starting to show revenues in Q4 of this year. This is going to be the same with SoCal.

SOCOM is going to address a niche portion of the AI stack, AI infrastructure. But the adoption of LP is going to happen. It's not going to happen fast. It's not going to be the same content as the current content of standard memory, but it's important for us to have that as part of our portfolio, while we help our customers and ecosystem partners to deploy their solutions in the market.

Sebastien Cyrus Naji

Great. Okay. That's very helpful. And then maybe my second question or my follow-up for Sumeet on gross margins. looks like non-GAAP product gross margins were about 60.4% in Q3. That's on the lower end of the, I think, 60% to 63% near-term range that you gave us. Could you maybe give us a sense for how much of the gap here is mix in terms of just more companion chip revenue, next-generation RCDs with early yields versus how much of it is wafer substrate or OSAT cost inflation. And then how should we think about Q4 product gross margins? Do they stay in that lower 60% area? Or can they move up a little bit?

Sumeet Gagneja

Yes. Thanks for the question, Sebastian. Yes. So our gross margin historically has been despite ban 60% to 63%. And you're right, in the Q3 was slightly above 60%. Our long-term target remains, which is 60% to 65%. In the near term, it's really the margin trending towards the lower end is primarily driven by the supply chain input cost. And we've been very successful in offsetting that cost input cost by driving internal cost savings and keeping our product gross margin in the range of 60% to 63% in the near term.

Q4, it's the same sort of setup going into Q4, but the investments and the cost reductions we have done especially in our operations side, there may be a slight uptick in the gross margin in Q4, but it's raw material, but it's still within the 60% to 63%. On a full year basis, it's more important to look at from the gross margin perspective. we expect 2026 to be right in the middle of that 60% to 63% range.

Your next question comes from the line of Mark Lipacis with Evercore.

Mark Lipacis

I had 2. I was hoping you could just talk about lead times from your own suppliers and any to extent that you're seeing tightening of supply on the front end of the back-end foundry business? And then Elie, can you talk about lead times to your customers? Are there any stretching of lead times to your customers from you? And any indication of your customers downstream or the supply chain downstream is increasing their own inventories given how tight everything seems to be becoming?

Luc Seraphin

Thanks, Mark. I'll start and let Sumeet comment. I would say that on the supply side, we do see lead times increasing. We signaled this 2 calls ago, we were expecting this. But because we were expecting this, we also put in place plans to mitigate for that. So we lever our strong balance sheet to actually build inventory on products that we believe are going to grow substantially with our customers, and we're in constant relationship with our suppliers to make sure that we use our balance sheet to make sure that we can supply to our customers.

So yes, definitely, longer lead times on the supply side, but it has not impacted our Q3 number, and it will not impact the Q4 number that we just talked about. So we've been able to manage that. But we have to continue to do that. Our lead times, the first approximation, our lead times to our customers have not increased at this point in time. But you understand that we are in constant discussions with them as well. the whole chain is tightening. The good thing is our business is very focused. We have very strong partnerships with our customers. and we work with them in making sure that we can supply what they need.

In summary, longer lead times on the supply side, we are using our balance sheet to deal with that. And at this point in time, we've not increased our lead times to our customers.

Mark Lipacis

And look, and just to be clear, do you have the ability to see if customers or customer customers downstream or increasing their inventories? Or is that like a black box to you, and it's really hard to determine.

Luc Seraphin

It's very hard to determine. We see -- what we see is that people place backlog earlier than what they used to a quarter ago or 2 quarters ago. I think everyone understands the current situation. So we have better visibility in the backlog. But at the same time, that gives us more opportunity to have a deeper, I would say, relationship with our customers once we understand the profile of their backlog then it's easier to work with them on how we can lead that backlog. So we don't see people building inventory, but we see people placing backlog.

Your next question comes from the line of Tristan Gerra with Baird.

Tristan Gerra

So if I heard well, you mentioned that your revenue in the quarter and the guidance is not constrained by supply. So it probably provides a little bit of a easy comp were just in the first half, where you did face some supply issues. What's your level of confidence that you can actually need to be accelerating demand that you described into next year? And I know you're not guiding beyond this quarter, but do you think that the acceleration that you're seeing in product revenue year-over-year is sustainable? Or do you see supply as an issue again next year? And is there any talk about longer-term agreements or anything that customers are trying to set up to ensure supply for you.

Luc Seraphin

So we see demand -- thank you, Tristan. We see demand strengthening into next year, and we started to work with our supply chain partners to meet what we believe is going to be required. In all honesty, this is something that we work on almost on a weekly basis. We try all avenues to support our customer base. So demand is strong going into 2027. Supply will remain tight, but as I said, as we did in 2026, we're working early with our supply base to look at every not we can turn to support our customer demand. that's how we look at this.

The good news is that the demand for the products we have in our portfolio is strong. The demand for CPUs, this CPU to GPU ratio is going in our favor. It's known from our customers all the way down to our suppliers. and we'll do our best to supply that growing demand into 2027.

Tristan Gerra

Great. And as a quick follow-up, I wanted to explore the difference in content opportunity medium term for x86 CPU and stand-alone Vera and cannot come up with maybe a for content in XED6 CD4o versus what you would get on the SOCEM-2side with -- but are you quantifying at all what the opportunity is and and the difference that you see in terms of opportunities on the XB6 and the on-base of CPUs next year and the years beyond.

Luc Seraphin

Yes. Thank you, Tristan. The way we look at it and the reason we are excited about this AI infrastructure deployment is that we look at this in an aggregate way. There are areas of AI like if you take the head nodes, for example, where -- SoCam and LTE memory can be used. It's not always used, but it can be used. And that's an opportunity for us from a technology standpoint. It allows us to develop our LP technology on all fronts.

But in aggregate, you do have a growth in these head nods that will create an opportunity for SoCAM, but you have higher growth in the traditional servers with a refresh necessary in order to continue to develop the standard range of applications, a range of standard applications. We have a higher growth in agentic standard CPUs as well for orchestration, tools management, memory management. So in aggregate, if you take the heads where you can have SOCAM.

And if you take the standard servers and the agentic server, the whole market is growing, but the majority of the growth is coming from CPUs with standard memory subsystems. So that's the way we look at it. We definitely don't look at this as SoCAM is cannibalizing the market for standard dam. It's actually complementary. It makes the system more efficient. The standard memory subsystems are going to increase at a higher pace going into 2027.

And the head nodes will drive new technologies like SoCAM to maximize this kind of application. So we see this as complementary. And that's why we want to have solutions for all of that. We really want to be agnostic to the memory subsystems while the infrastructure for AI is growing in the market? Because as that infrastructure is growing in the market, we're going to see hetrogenous system, and it's important that we have solutions for each 1 of those. But the vast majority is going to continue to be CPU with a standard GM configurations.

Your next question comes from the line of Kevin Cassidy with Rosenblatt Securities.

Kevin Cassidy

And I'll echo the congratulations on the great quarter. Just -- it's interesting, as you mentioned about the custom chips and that you're getting involved earlier into the design cycle. And I'm just wondering if -- is there any way does this help you to win more modules on those designs as they come into production?

Luc Seraphin

Thanks, Kevin. We're really excited with this silicon IP engagements with the ecosystem because they give us great insight into the architectural trends that these people are talking about. When we talk to hyperscalers with the opportunity for us to sell our silicon IP, we have insights into some of the architecture problems they're trying to resolve and where they see the world going. And as a consequence of that, that helps us develop -- continue to develop the right road map of products for this type of products.

But it also gives us insight as to the overall architecture of their systems and where they are going to be used, where LP is going to be used and why. What generation of DDR is going to be used and why? It just gives us that channel of information. It's almost through the discussion, and it gives us a good sense of the trends in terms of what type of technologies they are going to use not only on the silicon IP side, but also in terms of how they will configure their systems with different types of modules.

Kevin Cassidy

Right. And it seems like a big advantage over your 2 competitors that don't have IP story. And maybe just on the inventory 1 more time. Are you comfortable with the days of inventory now? Or should we expect to see that continue to increase even with the increasing demand next year?

Sumeet Gagneja

Yes, Kevin, good question. So inventory, as you mentioned, we've been growing inventory this year. In Q3, we grew it again $12 million, again, primarily leveraging the strength of our balance sheet to make sure we pared gridsurance to our customers. In Q4 as well, looking at, just like Luc mentioned throughout the call, like we have more visible look into the backlog and as demand is accelerating, we do plan to build increased inventory even in Q4 similar levels to like we build in Q3 and Q2.
