シリコム（SILC）2026年第3四半期決算説明会：売上高は71%急増、ガイダンスを上方修正

要約

• 2026年第3四半期の売上高は前年同期比71%増の2,670万ドルとなり、経営陣の2,500万ドル〜2,600万ドルのガイダンス予想範囲を上回りました。
• Silicomは、当初の計画よりも早く四半期ベースのNon-GAAP黒字化を達成しました。純利益は30万ドル（1株当たり0.04ドル）となり、前年同期の210万ドルの赤字から改善しました。
• 売上総利益は63%増の810万ドルとなりました。売上高が71%増加したにもかかわらず、営業費用は9%の増加にとどまり、営業レバレッジの発揮を示しています。
• 経営陣は、2026年通期の売上高ガイダンスを6か月前の8,200万ドル〜8,300万ドルから9,600万ドル〜9,800万ドルに引き上げました。第4四半期の売上高は2,700万ドル〜2,800万ドルと見込まれています。
• Silicomは2026年の最初の10か月間で8件のデザインウィン（採用獲得）を確保し、2025年通期の合計実績と同数となり、当初の2026年目標である7〜9件の下限に達しました。
• 経営陣は、最近獲得したデザインウィンと、エッジシステム、Smart NIC、FPGAソリューション、AI推論、ホワイトボックススイッチ、耐量子暗号（PQC）にわたる幅広いパイプラインが、2027年以降の持続的な成長を支援すると見込んでいます。

主要財務データ

特に断りのない限り、同社はNon-GAAPベースで業績を発表しています。

2026年9月30日時点で、運転資本および有価証券の合計は1億700万ドル（1株当たり約18ドル）となりました。Silicomは現金・現金同等物および高格付の有価証券を4,500万ドル保有しており、無負債経営を維持しています。高品質な在庫の合計は7,300万ドルでした。

直近12か月間において、北米が売上高の78%を占め、欧州およびイスラエルが11%、極東およびその他の市場が11%を占めました。米国の主要顧客1社が売上高の約13%を占めています。

事業および業績の動向

経営陣は売上成長の要因として、主にSilicomのコアポートフォリオ全体における出荷量の増加と、顧客による導入の加速を挙げています。前年同期比の売上高成長率は、2025年第4四半期の17%から、2026年第1四半期に33%、第2四半期に59%、第3四半期に71%へと加速しました。

Silicomは第3四半期中に2件のデザインウィンを獲得しました。既存の優良顧客が、標準仕様のサーバーアダプターおよびFPGA Smart NICの以前の採用に続き、カスタム仕様の高速サーバーアダプターを採用しました。経営陣は、この顧客からの総売上高が2026年の約300万ドルから2027年には1,000万ドル近くに増加すると見込んでいます。

新規のTier 1クラウド型サイバーセキュリティ顧客が、5G接続機能を統合したSilicomのエッジネットワーキングデバイスを採用しました。この顧客は初期注文を行っており、2026年末までに本格展開（ランプアップ）が開始される見込みです。経営陣は、フル稼働時のこのデバイスによる年間売上高が500万ドルを超えると予測しています。また、Silicomは同顧客とエッジAI用途向けのGPU統合製品を含む、よりハイエンドなエッジデバイスの検討も進めています。

AI推論分野において、Silicomは既存顧客からの初期量産注文を納入中であり、追加注文の獲得を目指しています。また、同社は別の見込み顧客とデュアルソース（複数購買）機会に関して交渉の最終段階にあります。

経営陣による業績予想（ガイダンス）

通期ガイダンスの上方修正は、Silicomにとって2026年内で2度目となります。経営陣は第4四半期の成長が第3四半期の収益性をさらに大きく上回ると見込んでいますが、具体的な利益目標は提示しませんでした。

経営陣は2027年の成長に対しても前向きな姿勢を維持していますが、具体的な数値によるガイダンスの提示は見送りました。成長を牽引する要素として、デザインウィンの導入本格化、2026年中に獲得された追加案件、ならびにパイプラインの商談化（コンバージョン）の進展などが挙げられます。

リスクと注視点

• AI推論分野における購買決定および製品の導入には、意思決定期間の長期化、初期導入期間、および本格稼働までの長期間のサイクルが伴う可能性があります。
• あるAI推論の見込み顧客は、戦略的方針の変更に伴い、最近プロジェクトを一時中断しました。
• デュアルソース戦略は新たな機会をもたらす一方で、既存顧客における競合ソリューションの参入を許すリスクも生じさせます。ただし、見込まれる年間出荷量が数万台規模に達する可能性があるため、経営陣はこの傾向をリスクよりも機会が大きいと捉えています。
• 売上高は地理的に引き続き北米に集中しており、直近12か月間の売上高の約13%を米国の1顧客が占めています。

アナリスト質疑応答のハイライト

経営陣によると、一般的なデザインウィンは獲得から約6か月後に売上を計上し始め、約12か月で本格展開（ランプアップ）段階に達します。その後、売上高は確立されたランレート（年間換算売上）付近で推移するのが一般的です。2026年に記録された力強い成長は、主に2026年前半に獲得された案件ではなく、2025年以前に確保されたデザインウィンを反映したものです。

デザインウィンは通常3〜5年間、時にはそれ以上にわたって継続します。また、既存顧客が低速アダプターから高速ネットワークアダプターへの移行など、製品の更新（リフレッシュ）のために再び採用を検討するケースも頻繁にあり、追加のデザインウィン獲得の機会につながっています。

AI推論について、経営陣はデュアルソース（複数購買）がSilicomの設計製品を他社が製造することではなく、競合サプライヤーの製品が併用されることを意味すると説明しました。Silicomは、FPGAベースおよび汎用（商用オフザシェルフ）ソリューションの両方を提供できる強みにより、さまざまなコストおよび性能の要求に対応可能なポジションにあると考えています。

Liron Eizenman

Thank you, Kenny, and good day, everyone. I'm very happy to share another truly outstanding set of results for the third quarter of 2026. Results that surpassed our guidance and that clearly show that our strategic plan and our business are performing significantly better than we planned. Very importantly, this quarter, we returned to profitability, well ahead of our plan.

As we look towards the end of 2026 and into 2027, I'm excited about Silicom's continued momentum, the clear visibility we have and the vast opportunities before us. The third quarter was a truly exceptional one for Silicom, showing a strong acceleration of the growth inflection that we have been talking about all year. Revenues for the third quarter came in at $26.7 million, up an outstanding 71% year-over-year and ahead of the $25 million to $26 million guidance range. Equally important, thanks to strong execution and the inherent leverage in our business model, we have returned to profitability with positive non-GAAP net income this quarter, well ahead of our initial expectation.

Our revenue growth is fundamentally volume-driven, fueled by higher unit shipments across our core portfolio and accelerating customer deployments. You can see the acceleration in our business clearly in the trajectory of our revenue growth over the past few quarters.

In Q4 2025, we reported 17% year-over-year growth, followed by 33% in Q1 this year, 59% in Q2, and now 71% in Q3. And our guidance for the fourth quarter points to continued very strong growth at a similar level of 66% year-over-year at the top of the range. Our business is now built on a highly predictable platform of recurring revenue based on years of Design Win momentum. As our recent Design Wins ramp up, they add to the base, and that is what is driving this sharp inflection in our business.

With this strong momentum, we are once again increasing our revenue guidance for the full year 2026 to a range of $96 million to $98 million. This follows an increase in our 2026 guidance last quarter and is another indication of how we are performing well ahead of our expectations. As I often discussed, the long-term growth and strength of our core business are best tracked via our Design Win momentum. The Design Wins we secure today drive our growth for years to come, which makes them one of the most important indicators of our future performance.

I want to discuss why our Design Win translate so powerfully into revenue growth. First, every new Design Win is additive to our existing base of business. This base of active Design Wins continues to generate a stable recurring stream of revenue and each new win adds further revenues on top of it. Second, many of the Design Wins we have secured in recent years are now in their strong growth phase, ramping up from initial orders towards full-scale deployment. It is the combination of those 2 effects, new wins adding to the base and recent wins ramping up, that's additive, that is driving the strong revenue growth you are seeing today, and that gives us great confidence in our continued growth ahead.

As you may remember, at the beginning of the year, I announced that for 2026 as a whole, we were targeting between 7 and 9 new Design Wins. I'm very pleased to report that we have secured 8 new Design Wins this year, already matching our total for the full year 2025. With 2 months of 2026 still to go, we have already exceeded the low end of our target range, and we are on track to meet or even exceed its upper end.

I want to spend a few moments discussing the 2 Design Wins that we secured during the third quarter. In July, an existing blue-chip customer awarded us a new Design Win for a custom high-speed server adapter, which we engineered to exact specification for a distinct use case within PC infrastructure. Having already integrated one of our off-the-shelf server adapters as well as FPGA Smart NIC, this customer came back to us for a fully custom product. This win is expected to grow our total business with this customer from approximately $3 million in 2026 to nearly $10 million next year.

More recently, in September, we secured a Design Win with a new customer, a Tier 1 cloud-based cybersecurity giant for a Silicom edge networking device with an integrated 5G wireless connectivity. After evaluating our solution for many months, the customer selected Silicom specifically for the strength of our integrated cellular connectivity, which proved to be a key differentiator in a highly competitive process. The customer has already placed an initial order with ramp-up expected to begin before the end of this year. At full ramp-up, we expect revenues from this Design Win to exceed $5 million annually for this device alone.

In parallel, we are evaluating additional higher-end edge devices with this customer, including a GPU-integrated edge device designed for edge AI use cases. Those wins are a good example of how our strategy works. We continue to grow our business by securing Design Wins with both new and existing customers, and each successful Design Win opens the door for further wins, often with satisfied customers coming back to us for additional products and additional use cases. Those types of wins reflect the long-term trusted supplier relationships we have cultivated over many years of operations with leading blue-chip customers. Importantly, together, we expect them to make a significant contribution to further growth in 2027 on top of the very significant growth we are already delivering in 2026.

Beyond the wins already secured, our pipeline of opportunities remains very broad and deep, spanning our entire product portfolio, Edge systems, Smart NICs and FPGA-based solutions as well as AI Inference, White Box Switches and Post-Quantum Cryptography across both new and existing customers. We expect this pipeline to continue converting into Design Wins, laying the ground for sustained strong growth well beyond this year.

Turning to our outlook for the fourth quarter. Based on the predictable recurring revenues from our Design Wins platform, we expect revenues in the range of $27 million to $28 million, representing 66% year-over-year growth at the upper end of the guidance. For the full year, we have raised our revenue guidance to a range of $96 million to $98 million, representing 57% year-over-year growth. This is the second time this year that we have raised our full year guidance, which stood at $82 million to $83 million just 6 months ago.

I also want to emphasize a particularly important milestone. Last quarter, we told you that we expected to return to quarterly non-GAAP profitability during the second half of the year. We have already achieved this in the third quarter, driven by our strong execution and the significant inherent leverage in our business model and with the strong growth we expect in the fourth quarter, we expect to build significantly on this profitability in the coming quarter. This is an important turning point for Silicom, and it shows the earnings power that our growing revenues are starting to unlock.

Let me now turn to the AI Inference market, where we continue to see tangible and significant potential. The AI networking and interconnect market is highly dynamic, requiring rapid architectural changes. This plays directly to our core strength of quickly tailoring sophisticated solutions. As a direct result of those fast-moving dynamics, our pipeline is highly active. We are in final discussions with new customer with a new customer about the major evolving use case, and we expect to reach an agreement very soon. Conversely, another prospect recently suspended the project to change their strategic direction. We have a strong track record of thriving in exactly this kind of fluid environment. To secure their supply chain, inference players are increasingly adopting dual-source strategies. Because those customers anticipate needing very high product quantities in the range of tens of thousands annually, they believe they will have sufficient volume to support both sources. This shift represents a strong long-term net positive for Silicom, opening up far more opportunities than risks.

While one of our current customers now has a dual-source option, this broader trend is already driving new pipeline growth, including at least one new prospect currently evaluating us for their dual-source plans. We are uniquely equipped to capture those expanding opportunities. Our ability to deliver both FPGA-based and COTS-based solutions ensures that we can provide the most cost-effective high-performance architectures to ASIC inference companies as they scale. Ultimately, the behavior of decision-making and extended time frames in the AI Inference space closely mirror those of our traditional markets. Success in this environment requires patience and a readiness to provide consistent long-term support through very long product introductions, initial deployments, and ramp-up periods. We are fully prepared to navigate those extended cycles, having executed exactly this playbook across similar markets for more than 30 years.

Finally, this brings me to our continued balance sheet strength, which provides us with the flexibility to invest in our growth while maintaining a conservative financial profile. At the end of September, our working capital and marketable securities totaled $107 million, representing approximately $18 per share, of which $45 million in cash, cash equivalents and highly rated marketable securities with no debt.

In summary, this was another excellent quarter. It reinforces our confidence in the strength of our target market, the effectiveness of our execution and the soundness of our strategic plan, and it is a very exciting time for Silicom. Our business delivered 71% year-over-year revenue growth in the third quarter, ahead of our guidance, and we have returned to non-GAAP profitability well ahead of our original time line.

Our Design Win engine is firing on all cylinders with 8 Design Wins already secured this year, and we have once again raised our full year revenue guidance to $96 million to $98 million, representing 57% year-over-year growth. Most importantly, the strong base of design wins we have built together with our very broad pipeline of opportunities position us -- position our business very well for continued growth in 2027 and beyond.

Taken together, those achievements clearly show that we have passed an inflection point. Customer demand is stronger and our broad momentum continues to build. With accelerating revenues and our return to profitability, we expect to close 2026 on a high note, carrying this exceptional momentum into a highly promising 2027. We look forward to delivering continued strong growth and returns to our shareholders in the quarters ahead and over the long term.

With that, I will now hand the call over to Eran for a detailed review of the quarter results. Eran, please go ahead.

Eran Gilad

Thank you, Liron, and good day to everyone. I will review the financial results and business performance for the third quarter of 2026. Before beginning the financial overview, I would like to remind you that unless otherwise indicated, all financial results are non-GAAP. A full reconciliation of our results on a GAAP to non-GAAP basis is available in the press release issued earlier today.

We are very happy with our revenues for the third quarter of 2026, which were $26.7 million, 71% above the $15.6 million reported in the third quarter of last year. The geographical revenue breakdown over the last 12 months was as follows: North America, 78%; Europe and Israel, 11%; Far East and the rest of the world, 11%. During the last 12 months, we have one 10% U.S. customer, which accounted for about 13% of our revenue.

Gross profit for the third quarter of 2026 grew 63% to $8.1 million compared to a gross profit of $5 million in the third quarter of 2025. Our gross margin of 30.3% in the quarter is comfortably within our expected short to midterm gross margin range of 27% to 32%. Operating expenses in the third quarter of 2026 were $8.1 million compared with $7.4 million reported in the third quarter of 2025. I highlight that this is an increase of only 9% year-over-year compared with 71% revenue growth, a clear demonstration of the operating leverage inherent within our business model.

Operating income for the third quarter of 2026 turned positive just above breakeven at $20,000, a significant improvement from the operating loss of $2.4 million reported in the third quarter of 2025. Net income for the quarter was $0.3 million compared with a net loss of $2.1 million in the third quarter of 2025. We are delighted to have returned to quarterly non-GAAP profitability in the third quarter, well ahead of our initial expectations.

Earnings per share in the quarter were $0.04 compared with a loss per share of $0.36 in the third quarter of last year. Now turning to the balance sheet. As Liron mentioned, as of September 30, 2026, our working capital and marketable securities amounted to $107 million including $73 million in high-quality inventory and $45 million in cash, cash equivalents and highly rated marketable securities with no debt.

That ends my summary. I would like to hand back to the operator for a question-and-answer session.

Operator

[Operator Instructions] The first question is from Ryan Koontz of Needham & Company.

質疑応答

Ryan Koontz

Great quarter, guys. Really great quarter. A few questions, if I could, please. Just can you start with reminding us what the revenue ramp? I know there's different scales of different design wins, obviously. But can you remind us of the timing of revenue ramps typically from the time that you announce a win? Are we talking 2 quarters to start small and maybe gets material in 3, 4 quarters? If you could just comment on that, just to reset the expectations here on these Design Wins, that would be really helpful.

Liron Eizenman

Yes. I mean, obviously, it differs from one Design Win to another. But usually, it's going to be in the range of 6 months. We start seeing the revenues coming in 12 months, we see the ramp-up. And then usually from that point on, it's basically continuing at the sort of run rate.

Ryan Koontz

Really helpful. So this really exemplary growth you're delivering here in the second half with a really strong acceleration exceeding 50%. These are design wins, I assume then the primarily contributors here are design wins you secured in the second half of '25. Is that a good way to think about it?

Liron Eizenman

Before, yes. But it's definitely not the Design Wins we secured in the first half of this year, those will be mainly contributing for the years to come. So everything we're seeing right now already in the growth in the revenue numbers are Design Win we achieved either in 2025 or some of them even earlier than that.

Ryan Koontz

Yes. Great. Great to hear that. And then I know you've talked in the past about this inference Design Win and the potential for this to -- any updates for us there? I know investors are keenly interested in that opportunity, but can you share any updates on your view of the opportunity and timing?

Liron Eizenman

Yes. We continue to be very excited about this opportunity, obviously, and we're seeing good momentum with this customer. And I definitely hope we will have some updates for you soon. Right now, it's still moving forward good. As we published, we got the first production order. We're working on delivering it and also working on trying to secure additional orders.

Ryan Koontz

Got it. Super. And if you could clarify -- your microphone is a little fuzzy. It's a little bit hard to hear you on this call, to be honest. But you had the comments about dual source. This is from an existing design win you have that's going to dual source? Or can you clarify your comments there?

Liron Eizenman

Absolutely. So the comment was general not about the specific Design Win or a specific customer. It's about the industry. So as those AI inference players are advancing and becoming more mature, they understand that they need a dual source strategy. And this is something we're very familiar in the market for many, many years. So we're starting to see more and more of that. That obviously the 2 ends. One side is good because it opens up more customers that today are maybe not working with us, maybe working with someone else, and suddenly they come to us, and we have such a case actually right now where we are entering, I would say, very last discussions with the customer about becoming their dual source.

And on the other side, yes, it may also be a situation where we are working with someone and that someone will have a dual source strategy. But the good news is the quantities are very, very high. That's what we hear from all those guys. It's in the tens of thousands per year. So even with a dual source strategy, the volumes that we can get even for one customer could be very big.

Ryan Koontz

Sure. That's really helpful. And these designs, this is -- obviously, this is a different sourcing strategy, different manufacturers, but this is also from a different design vendor making a different product that does serve the same requirements as yours? Or is it your design being manufactured by different manufacturers?

Liron Eizenman

It would not be our design manufactured by someone else. It will be a competitive solution from someone else. But if I think about it as a whole, I think for us, it's -- I mean, less risk and certainly more opportunity for us to sum it up in my view.

Ryan Koontz

Got it. That's really helpful. And any help for us on how we should think about the growth opportunity here in '27? I mean do you think this momentum you're seeing in the second half, can we safely say you expect that to carry forward to calendar '27?

Liron Eizenman

I'm personally very excited about '27. There's no numbers I can share right now. But in general, we believe we will continue to grow, and we believe we have a good momentum both on Design Wins that should ramp up and both on new stuff that we're still doing this year and planning to see the impact of that next year. So very, very excited. We'll continue seeing the growth, I believe. But the exact number is too early for me to provide.

Ryan Koontz

Fair. Maybe one last one if I could squeeze it in. Just if you think about your, we'll call it, legacy business from Design Wins before 2024, for example, Design Wins '23 and before, do you have any idea of that -- the stabilization of that business? I mean is it in modest decline? Is it essentially flat now? Or can you help us with your long-established business with the trajectory of that even here in the second half of '26, what is the mix of kind of old versus new Design Win in terms of growth?

Liron Eizenman

So usually, when we have a Design Win, usually it will stay at least for 3 to 5 years, sometimes even more than that. So even Design Wins that we achieved in '24, '23, very likely they will stay with us this year and next year, maybe also in '28. But a lot of times, it's a Design Win after Design Win. So as I mentioned before, if a Design Win with another customer get the same customer later on. So if they bought from us, for example, you mentioned legacy, I wouldn't call it legacy, I would say our core business, for example, one of our network adapters. And now they are going to do a refresh next year, they will probably come to us and they will say, okay, we had lower-speed adapter 3 years ago, now we want to go to a higher speed you guys have, that would be like the automated process for them. And then we will just do a new refresh, new Design Win with those guys and that happens a lot. So even those Design Wins that are running for 3, 4 years, more than that, when they do a refresh, they come to us.

Ryan Koontz

Congrats on a great quarter.
