Amphenol Reports 134% Growth in Datacom IT Segment

Amphenol plays an important role in Nvidia’s NVL72 racks that are shipping now, as the company supplies high-speed copper cables and interconnects. Nvidia’s choice to use copper cabling over optical transceivers resulted in both lower costs and power savings for the NVL72, providing a growth opportunity for Amphenol. Specifically, Amphenol's 12VHPWR PCIe 5.0 power connector was able to eliminate the need for three power connectors with a single power connector.

Unlike other GPU-agnostic players who can realize growth and tailwinds as long as AI capex remains strong, Amphenol is more closely correlated to Nvidia’s NVL72, and its opportunity thus arises squarely from the ramp of the platform and overall shipment volumes. Signs that Nvidia is now quickly ramping NVL72 shipments far ahead of analyst expectations support more growth ahead for Amphenol in the upcoming quarters.

However, Amphenol remains quite highly exposed to slower-moving sectors such as the industrial and automotive sectors, and cash to debt is upside-down due to its focus on M&A to complement growth.

Nvidia’s Choice for Copper over Optics

Although we have discussed the industry’s transition to optical modules for AI due to the rising data requirements and ability to solve the bandwidth bottleneck, for now, Nvidia is foregoing optics for copper in the GB200 NVL72 for two main reasons: cost and power.

Should Nvidia have selected to use 1.6T twin-port optical transceivers, power consumption for the NVL72 would have been ~20kW higher at up to 140kW, as it would have needed 648 modules (72 ports times 9 NVSwitch trays) each consuming ~30W.

The GB200 NVL72 was already severely pushing the limits of data center cooling infrastructure, and overheating issues were the rumored primary cause of shipment delays. Ditching optics helped drive power consumption lower without constraining performance.

Transceiver costs are also quite expensive, and at ~$900 per module, this would equate to over half a million in added costs per rack, before Nvidia’s margin markup. These additional costs and added power consumption would throw NVL72’s TCO out the window.

Copper results in lower cost and power consumption with copper cables approximately one-sixth of the cost at ~90% lower power consumption. Additionally, Amphenol’s Paladin HD and Paladin HD2 backplane interconnect cables provide up to 224G PAM4 data transfer rates, the same as a similar 1.6T transceiver, with low insertion loss and high performance. These cost and power advantages make copper a more suitable selection for the rack scale platform for both TCO for customers as well as overall power draw.

Amphenol’s Role in Nvidia’s GB200 NVL72

Amphenol’s opportunity arises from Nvidia’s use of copper cabling combined with its Paladin backplane and connectors. A report from SemiAnalysis states that the NVL72 backplane features these components from Amphenol:

A total of 144 Paladin HD 224G connectors (72 male, 72 female) for the NVLink5 connector
5,184 SkewClear EXD Gen 2 cables
36 Paladin HD 224G connectors for the backplane
36 2 UltraPass OverPass 224G connectors terminating to a Paladin HD female connector
4 DensiLink OverPass cables

Amphenol’s Paladin HD and HD2 connectors support both 800G and 1.6T PAM4 bandwidth requirements, maximized for performance with a 50% density increase versus the first-gen Paladin, allowing for more connections in limited PCB spaces. Amphenol says the connectors have the lowest crosstalk in the market and low insertion loss, which are critical for high-speed data transmission. The connectors are versatile, supporting direct backplane traces and cable-based architectures, enabling flexible deployment options in different server rack designs.

The SkewClear EXD Gen 2 cables also support 800G and 1.6T PAM4 bandwidth requirements and were designed for maximum reach and density for OSFP, Paladin HD2, and UltraPass-based systems. The cables offer better signal integrity than traditional PCB or standard twinax and lower insertion loss, while Amphenol says it can offer customers the “lowest total applied interconnect link cost” for OverPass assemblies.

The UltraPass OverPass 224G assemblies are the highest differential pair count interconnect available on the market, offering full 1.6T support, high signal integrity performance with low loss interconnect. Amphenol says it also reduces overall system costs by eliminating the need for re-timers and PCB laminates. The interoperability with SkewClear cables and Paladin connectors provides high performance in dense, thermal-constrained racks, hence Nvidia’s selection of the products.

The DensiLink OverPass cables create a double-ended high performance cabling interconnect and remove high speed signaling from the PCB, allowing for reduced design complexity and lower PCB costs. Nvidia used the DensiLink cables in the DGX H100/H200 platform to connect the CX7 networking chip to the OSFP ports.

GB200 NVL72 Shipments Accelerating, What This Means for APH

Amphenol’s dollar content per NVL72 rack is expected to be quite high — Evercore ISI estimated last year that Amphenol’s BOM content was in the range of $100,000 to $120,000 per NVL72, or around 3-4% of the server’s value. This represents a fairly large opportunity for Amphenol, especially if Nvidia is scaling shipments to a much larger degree than currently anticipated.

As we had discussed in our post-earnings Nvidia analysis, the GB200 NVL72 has ramped from ~1K racks in all of Q1 to ~1.5K racks for April, now to ~1K racks per week as of the end of May, per Jensen Huang:

“On average, major hyperscalers are each deploying nearly 1,000 NVL72 racks or 72,000 Blackwell GPUs per week and are on track to further ramp output this quarter.”

Analysts were estimating Nvidia’s quarterly rack shipments to reach 4-6K in Q2, building on April’s ramp, before reaching 8-10K shipments in Q3; however, Huang’s comments imply that Nvidia is shipping at a much faster cadence, more along the lines of 12K racks per quarter, assuming the broader supply chain can support maintaining the 1K/week volume.

Nvidia’s statement that Blackwell revenue was nearly 70% of data center revenue in the quarter implies QoQ growth of nearly 120% to around $24 billion, as shipments begin to tick higher. Rough math implies hyperscalers are now deploying $3 billion every week of the NVL72 and ramping higher, or a $39 billion quarterly run rate.

For the full-year, NVL72 estimates still have a rather wide range, given the slow start to the year and limited visibility (until now) of the pace of the ramp. Nomura estimates that NVL72 rack shipments will reach ~20K for the year, while JPMorgan places shipments at 25K, with a stronger ramp into year-end.

Despite the strong ramp commentary and implied growth rates, analyst estimates for Nvidia have yet to be revised higher, suggesting that either there is an expectation for supply chain bottlenecks to constrain shipment growth or that there is room for shipments to meaningfully exceed estimates moving forward.

Dramatic Token Growth Supports Strong GB200 Ramp

While the ultimate pace of the GB200 ramp may boil down to Nvidia’s complex supply chain and the quarterly or weekly output volumes that it can sustain, strong token generation growth and high demand for AI services at the hyperscalers supports the accelerated ramp the platform is seeing.

Morgan Stanley says that “every hyperscaler has reported unanticipated strong token growth,” and that “everyone we talk to in the space is telling us that they have been surprised by inference demand, and there is a scramble to add GPUs.” The firm adds that “LLM cloud customers are requesting that in lieu of GB200 availability, their cloud partners add capacity of Hoppers and B200s.”

This is further supported by recent token growth statements from Microsoft and Alphabet. Microsoft stated in its Q3 earnings call at the end of April that it “processed over 100 trillion tokens this quarter, up 5x year-over-year, including a record 50 trillion tokens last month alone,” implying a sharp uptick in inference activity at the end of their fiscal quarter.

Nvidia revealed that Microsoft is expecting to ramp its GB200 capacity significantly: “Microsoft, for example, has already deployed tens of thousands of Blackwell GPUs and is expected to ramp to hundreds of thousands of GB200s with OpenAI as one of its key customers.” Quick back-of-napkin math shows that Microsoft could be ramping from 500 to 1,000 NVL72 racks to 5,000 racks to go from 36-72K GPUs to ~360K GPUs.

Alphabet also highlighted at its I/O 2025 Developer’s Conference that its monthly tokens processed were surging, up 50x YoY in April 2025 to more than 480 trillion. This is far, far above Microsoft’s volume, likely due to the prevalence of AI overviews in Search handling billions of visits. Growth in tokens price began accelerating exponentially in February, more than doubling in just two months.

Nvidia also backed this up in the earnings call at the end of May, stating that they also are “witnessing a sharp jump in inference demand [as] OpenAI, Microsoft and Google are seeing a step function leap in token generation.” Nvidia added that companies are seeing higher token generation rates with Blackwell: “inference serving startups are now serving models using B200, tripling their token generation rate and corresponding revenues for high-value reasoning models.”

The GB200 NVL72 provides significant boosts to token generation (throughput), allowing the hyperscalers and tier 2 CSPs like CoreWeave to handle increasingly large inference requests and serve these at lower costs. Nvidia claims that the NVL72 can offer up to 116 tokens per second per GPU, a 30x increase to the HGX H100’s 3.5 tokens per second per GPU on GPT-MoE-1.8T. This performance increase drives higher revenue for cloud providers such as CoreWeave and Microsoft’s Azure, and the NVL72 currently is the only platform that can sustain token growth at this exponential pace and scale.

Amphenol’s NVL72-Driven Revenue Opportunity

Blackwell’s ramp over the next few quarters could drive hundreds of millions to $1 billion-plus in revenue for Amphenol due to its rather high dollar content per NVL72 rack. Based on the $100K to $120K BOM content, each 1,000 racks shipped could correlate to $100 million to $120 million in revenue for Amphenol. Thus, the revenue potential for Amphenol stemming from the NVL72 is dependent on rack volumes, which are now accelerating.

For example, Q2’s estimated shipments could translate into a $400 million to $720 million revenue opportunity for Amphenol, while Q3’s could translate into $800 million to $1.2 billion revenue opportunity. However, if Nvidia is pushing the pace towards 12,000 racks per quarter, that could translate into $1.2 billion to $1.44 billion for Amphenol.

Assuming that the NVL72 opportunity also carries a slightly higher margin, such as at around 30%, this could provide some tailwinds to earnings as well – at $400 million in revenue, this would provide $0.10 in EPS, while the $1.2 billion opportunity could contribute at least $0.30 in EPS. Though this seems small, $0.10 to $0.30 represents 16% to 48% of Q1’s adjusted EPS.

Component sourcing timelines and revenue recognition dates likely means that Amphenol’s revenue will ramp quarter(s) in advance of Nvidia’s shipment ramp given the essential nature of Amphenol's components. Amphenol noted in its 10-K last quarter and its 10-Q this quarter that it does not have significant concentration with any single counterparty, implying that Nvidia remains a <10% customer, or below $480 million in revenue in Q1. Morningstar also estimated in January that AI-related connector shipments reached a $1 billion annual run rate, or ~$250 million per quarter. Based on estimated BOM content and Nvidia’s shipment growth, Amphenol likely still has more revenue upside available.

Upcoming GB300 Platform Shift

The upcoming shift to Blackwell Ultra (GB300), with production beginning at the end of this quarter for a second half ramp, also provides an opportunity for Amphenol even as the platform is expected to work in an upgraded CX8 networking chip and 1.6T optical modules.

Nvidia confirmed in Q1’s call that the “GB300 will leverage the same architecture, same physical footprint and the same electrical and mechanical specifications as GB200” to allow “CSPs to seamlessly transition their systems.” It is also expected that the GB300 will optimize copper cabling layouts to meet higher performance and data transfer speed requirements, resulting in 50% longer cable lengths. This design continuity should translate into stable BOM content for Amphenol as the next generation commences.

Tariff Risks for Amphenol’s AI-Related Products

China is not only a major market for Amphenol, contributing 16.5% of revenue in Q1 and 22.3% in 2024, but it is also home to a significant share of Amphenol’s manufacturing for connectors, interconnects, and fiber optic products.

Amphenol does not provide an exact breakdown for its China manufacturing exposure, though three of its four facilities listed on its high-speed backplane and cable connector data sheet are located in China, meaning that its primary growth driver at the moment may be overly exposed to China tariff risks.

In its 10-K, it was stated that the “imposition of additional tariffs or other trade barriers could increase our costs in certain markets and may cause our customers to find alternative sourcing,” or increase difficulties in selling products in some markets. This could have negative impacts on both revenue growth from lost sales and earnings from higher costs”

On the earnings call, the word tariffs came up 23 times with analysts poking around to see what the impact could be given Amphenol has 300 facilities in 40 countries. One of the more direct statements made from the questioning was the following: “Let's say that there's a slight impact on pricing as we go into the second quarter, and our team's going to work really well to moderate whatever impact could be on the bottom line. And I think implicit in our guidance, is that our margins are still very strong in the second quarter. So that must not be a tremendous impact.”

This led to questions on whether the current results were from a pull-in, with management stating there was a “slight pull-in" on mobile devices but not on IT datacom where demand outweighs supply.

Financials

Amphenol reported a significant beat in Q1, reporting revenue well ahead of consensus estimates and far above its guidance for $4.0 to $4.1 billion in the quarter. This strength was driven by 91% YoY growth in Amphenol’s Communications segment, fueled by strong demand AI data center products. Growth estimates have also been moving substantially higher throughout the rest of the fiscal year following Q1’s strong beat and a solid Q2 guide.

Revenue Growth Accelerating on Strong AI Demand

Accelerating AI demand drove Q1’s outperformance, with revenue coming in “much stronger than expected” at a blazing 47.7% YoY to $4.81 billion in revenue, accelerating 18 points sequentially. Organic revenue growth was 33%, accelerating 13 points sequentially.

Q1’s report marks a tremendous growth acceleration for Amphenol, with this being its first quarter with >40% YoY growth since 2006 and a remarkable 45 point acceleration in just 5 quarters. This is impressive considering more than two-fifths of Amphenol’s business remains in longer-cycle industrial and automotive end markets.

For Q2, Amphenol guided for revenue between $4.9 billion and $5.0 billion for YoY growth of ~37.5% at midpoint, coming in well ahead of the consensus estimate for $4.61 billion. This is likely once again driven by AI data center demand, though it points to Amphenol reaching peak growth for this ramp cycle.

Orders Surging

Amphenol’s orders have grown at 58% YoY for a second consecutive quarter, with growth accelerating sharply over the last few quarters.

Management had an important comment on order growth in Q1’s call related to the datacom segment: “We weren't able to meet our expectations. We far exceeded in the quarter our and our customers' expectations of what we could execute, but they still would have taken more, if we could deliver it.” This hints of more confirmation that Nvidia’s platform ramped much quicker than expected in the quarter, and that Amphenol could have driven higher revenue and stronger growth if it had an ability to meet said demand.

Revenue Estimates Rising Sharply

After Q1’s revenue growth came in more than 23 points ahead of guidance, estimates for the remainder of fiscal 2025 have risen rather sharply, with growth rates now nearly 10 to 20 points higher than at the start of the year.

For Q2, revenue was expected to be $4.24 billion in late January, but as of mid-May, that has been revised nearly $800 million higher to $5.01 billion as Amphenol continues capturing strong AI demand.
For Q3, revenue was expected to be $4.47 billion in late January, though that has also been revised nearly $700 million higher to $5.13 billion as of mid-May.
For Q4, revenue was expected to be $4.57 billion, though that has been revised nearly $700 million higher to $5.25 billion.

Putting this together, the nature of Q1’s beat and the strength in datacom at 134% YoY has driven estimates for the next three quarters up by more than $2 billion combined. This also came before Nvidia revealed that NVL72 shipments were ramping much faster than analysts anticipate, providing a major tailwind to datacom growth in the upcoming quarters due to Amphenol’s content on the platform.

In terms of YoY growth, here is what the revisions look like:

Q2’s growth is now expected to be 38.8%, more than 21 points higher than January’s 17.5% estimate.
Q3’s growth is expected to be 27.0%, approximately 16.5 points higher than in January.
Q4’s growth is expected to be 21.5%, nearly 10 points higher than in January.

Segment Breakdown: Communications Driving Revenue Growth & Quickly Gaining Share

Amphenol has three primary reportable segments, Harsh Environment Solutions, Communications, and Interconnect and Sensor Systems, though it also breaks down sales by end market (discussed next). These segments all serve many of the same end markets, such as industrial, auto, and datacom, so the end market breakdown provides a clearer view of what’s driving growth.

Harsh Environment Solutions includes ruggedized interconnect products, connectors and interconnect systems, specialty cables, PCBs and other products. Revenue for the segment rose 38.4% YoY, though growth was just 8% YoY organic, to $1.27 billion in Q1. The segment accounted for more than 26% of revenue in the quarter.

Communications Solutions includes connectors and interconnect systems, including high speed, radio frequency, power, fiber optic and other systems, as well as coaxial and high speed cables. Revenue rose 90.7% YoY and 73% organic to $2.41 billion, accounting for more than 50% of Amphenol’s revenue in the quarter.

Interconnect and Sensor Systems includes sensors, sensor-based systems and value-add interconnects. Revenue rose 5% YoY and 6% organic to $1.16 billion, or less than 24% of revenue in Q1.

End Market Breakdown

Amphenol serves a wide range of end markets, exposing it to both macro-related and tariff headwinds in core end markets like automotive, though strong AI demand in the datacom end market is turbocharging revenue at the moment.

Datacom revenue rose 133% YoY and 134% organically to 33% of revenue in Q1, with management saying that AI (predominantly GPUs) drove approximately 2/3 of that YoY growth, alongside “robust growth in our base IT datacom business.” This was a rapid acceleration from 76% YoY and organic growth in Q4 and 60% in Q3. For Q2, management expects high single-digit QoQ growth as AI data center investments continue to accelerate.
Datacom quickly emerged as the primary driver for Amphenol’s growth last year, contributing 50% of its $2.67 billion incremental revenue growth on a YoY basis. This robust growth points to datacom remaining in the driver’s seat again this year.
Industrial revenue rose 20% YoY and 6% organically to 20% of revenue in Q1, as “organic growth in the medical, instrumentation, alternative energy and rail mass transit markets more than offset moderations in heavy equipment and factory automation.” This decelerated from 26% YoY growth in Q4 though organic was flat at 6%. Management expects Q1 sales to remain roughly at Q1’s level.
Automotive revenue declined (2%) YoY and (1%) organically to 16% of revenue, as North American and Asian growth was “more than offset by a moderation of sales in Europe.” This was a slight uptick from (3%) YoY and organic growth in Q4. Management expects a slight sequential decline in Q2.
Communications networks (not to be confused with Communications Solutions segment) revenue rose 107% YoY due to the acquisition of the Andrew Business from CommScope, as organic growth was just 11%. Management expects high-teens QoQ growth in Q2 as it benefits from a full-quarter impact of the Andrew acquisition.
Defense revenue rose 21% YoY and 14% organically to 9% of revenue in Q1, driven by “broad-based growth across virtually all segments within the defense market and importantly across all geographies.” This accelerated from 16% YoY and 9% organic growth in Q4. Management expects Q2 revenue will grow in the high-single-digit range QoQ.
Mobile devices revenue rose 20% YoY and 20% organically to 7% of revenue, as soft tablet revenue only partially offset strong growth in smartphones, laptops and wearables. Management said Q1 benefited from some pull-in demand due to tariffs with growth accelerating from 15% in Q4. Amphenol expects a high-teens QoQ decline in Q2 as customers adjust production volumes for 2H 2025 product launches.
Commercial aerospace revenue rose 106% YoY but declined (3%) organically to 5% of revenue, as jetliner procurement volumes moderated. Topline growth was boosted by the addition of CIT, which was acquired in 2024. This decelerated from 137% YoY and 18% organic growth in Q4. For Q2, management expects revenue roughly equal to Q1.

AI Opportunities but Auto, Other Risks

Despite the AI opportunities, Amphenol remains fairly exposed to a handful of end markets that could face tariff-related headwinds through the remainder of the year – automotive, mobile devices, and even industrial.

As tariff fears surged in April, analysts noted that the automotive industry was likely to be hit quite hard by tariffs. A CNBC report stated that analysts and executives are “expecting to see a drop in vehicle sales in the millions, higher new and used vehicle prices, and increased costs of more than $100 billion for the industry.” While tariff policy is fluctuating quite rapidly, another pressure point for the industry has arisen: higher rates. This will weigh on vehicle affordability and could serve to dampen demand, as consumers may forgo purchases or leases due to rising costs.

The smartphone market was already on thin footing this year, with shipments rising 1.5% YoY in Q1, though IDC attributed this to a supply-side surge in shipments ahead of tariffs. IDC said this dynamic “effectively inflated Q1 shipment figures beyond levels anticipated based on underlying consumer demand trends alone,” adding that heightened geopolitical tensions between the US and China and growing tariff uncertainties were a “strong reason for concern” for 2025 growth. For the remainder of 2025, TrendForce estimated that the “best case scenario will see the smartphone market flat at best” in 2025, while the “worst case scenario is a production decline by as much as 5% YoY.”  

Industrial revenue growth has been quite slow organically at 6% in Q1, while manufacturing activity has now contracted for a third straight month, according to the ISM Manufacturing Index. Tariffs such as those on steel could pressure industrial activity, while other sectors like alternative energy remain plagued by rates impacting demand.

Overall, auto, mobile devices, and industrial accounted for 43% of Amphenol’s revenue in the quarter, and lasting challenges to growth, with auto now in negative territory, could offset datacom strength in the upcoming quarters.

Communications Provides Some Margin Tailwinds

Amphenol’s margins have been relatively stable over the past four quarters, but the strong growth and increasing contribution from Communications, which is accretive to operating margin, provides some margin tailwinds.

Gross margin in Q1 was 34.2%, up less than 1 point YoY and marginally lower sequentially. Gross margin has been expanding slowly, from the high 32% in late 2023 to the low 34% range.
Operating margin in Q1 was 21.3%, up just 0.3 points YoY and down 0.8 points sequentially. Adjusted operating margin was 23.5%, up 2.5 points YoY and more than 1 point QoQ.
Net margin was 15.3%, down 1.6 points YoY and 2 points sequentially. Adjusted net margin was 16.6%, up 1.2 points YoY and half a point sequentially.

By segment, Communications is seeing the strongest margins, with operating margin expanding nearly 5 points YoY to 27.4%; coupled with its robust growth and the largest revenue mix at 50%, Communications offers some tailwinds moving forward for Amphenol.

Harsh Environment Solutions’ operating margin has begun to recover, but remains below 2H 23 and early 2024 levels above 25%. Interconnect and Sensors has both the slowest revenue growth in the single digits and the lowest margins in the 18% range, providing a bit of a drag to margins.

EPS Growth Strong in 2025, but Decelerating Sharply After

Due to the rather stable nature of margins, Amphenol does not have much of a tailwind from operating leverage, with EPS growth mirroring revenue growth rates for this year and over the next few years.

Amphenol reported a quite large 21.2% beat on adjusted EPS in Q1, posting $0.63 versus the $0.52 estimate. This represented growth of 57.5% YoY, accelerating from 34.1% growth last quarter. However, similar to revenue, growth is currently expected to peak in Q1 and decelerate after, though remaining quite strong.

For Q2, management guided for $0.64 to $0.66 in adjusted EPS for growth of 47.4% at midpoint. Growth is expected to decelerate nearly 13 and 10 sequentially in Q3 and Q4 to exit the year at 25.5%, based on current analyst estimates.

For 2025, Amphenol is expected to report 40.8% growth to $2.66 in adjusted EPS, with growth forecast to slow dramatically to the 9% range for both 2026 and 2027, in an indication that 2025 is expected to be the sole strong growth year for the company due to Blackwell’s initial ramp phase.

Cash Flows

Amphenol’s cash flow margins have contracted slightly, as it reaffirmed a commitment to spend more on capex to support elevated datacom demand. Cash to debt remains upside down due to the company’s M&A strategy.

Operating cash flow was $764.9 million for a 15.9% margin, down from an 18.4% margin in the year ago quarter. OCF margin over the past three years has hovered between the 17% to 20% range, with Q1’s cash flow slightly weaker.

Free cash flow was $580.4 million for a 12.1% margin, down from a 15.5% margin in the year ago quarter. Management expects to have elevated capex again in Q2 to support datacom growth, weighing on FCF.

Cash and equivalents totaled $1.67 billion, while debt was $7.17 billion. Debt to equity sits at 0.7x. Amphenol has taken a very M&A forward approach, having made more than 50 acquisitions over the last decade to complement and drive growth, with 4 acquisitions since 2024 – these four have cost more than $4 billion combined. Cash and equivalents have hovered around this level for more than a year, but the nearly $3 billion YoY increase in debt due to the acquisitions further stresses the balance sheet and increases the likelihood that Amphenol will tap into more debt in the future.

Valuation

Amphenol is also rather richly valued, trading at a 10% premium to its 10-year PE based on FY25 EPS estimates, while at its highest cash flow ratios. These valuation risks come front and center as Amphenol looks to have put in its peak growth quarter on the top and bottom line, barring a significant acceleration.

Amphenol currently trades at ~34.5x forward EPS, nearly 10% above its 10-year average of 31.2x. The stock trades at a slight discount to the 40x multiple it held through late 2024, although Amphenol’s quarterly EPS growth is currently forecast to decelerate rather sharply from >40% in 2025 to <10% in 2026, which does not necessarily support more multiple expansion given the breadth of this projected deceleration.

On the top line, Amphenol is reapproaching peak multiples, trading at 5.5x forward revenue, versus its peak at 6x and its 4.5x 10-year average. Similar to EPS, Amphenol’s revenue deceleration does not easily pave a path for more multiple expansion, unless these Nvidia-driven growth tailwinds drive revenue growth much faster than anticipated for multiple quarters into fiscal 2026.

On a cash flow basis, Amphenol is trading at record high multiples over the past twenty years, and at significant premiums to historical averages. Amphenol currently is valued at 39x operating cash flow and 52x free cash flow on a TTM basis, a 50% premium to its 26x 10-year average for OCF and a 60% premium to its 33x average for FCF.

Conclusion

Amphenol is benefiting significantly from its high content on Nvidia’s GB200 NVL72 platform, offering a rather large opportunity ahead for Amphenol as shipments are projected to ramp faster than anticipated over the next few quarters. However, based off current estimates, Amphenol is already passing its peak growth quarter, and this combined with a richer valuation and potential tariffs in major end markets such as auto present some risks to this growth story. As with a few stocks right now, the risk/reward favors investors who attempt to get a lower price.

The lower margins point toward more commoditized products than others in the AI space. However, we continue to watch the company closely as NVL72 systems have only begun to ship and will ramp from here.
