Record Revenue, Record Orders: Why Amphenol Still Looks Undervalued

When we talk about AI firms, there are some names that always come up, vis-à-vis Nvidia (NVDA), Microsoft (MSFT), and Palantir (PLTR). And then there are companies that do the quiet, not so glamorous work that makes the concept of AI technology possible. Amphenol Corporation (APH) (NYSE: APH) is one of them. I would make my case in this piece as to why this company is interesting.

Amphenol makes most of the things that tie together AI data centers. This includes the connectors, fiber optic cables, antennas, and sensors. So when Microsoft or Amazon (AMZN) builds a new AI data center and stuffs it with Nvidia GPUs, every single piece of hardware in that facility needs to be connected. That is what Amphenol does. And interestingly for them, the demand for this has been growing.

I have been watching this company for some time, and after taking a closer look at its Q1 earnings report, I felt I needed to share my view on what is playing out here. The numbers are insane, but the stock has not exactly reflected what is happening. That’s why I think we may still be early.

The Business: What Amphenol Actually Does

Before we get into the numbers, it helps to understand what Amphenol is building. The company operates through three factions. The first is its Communications Solutions. This division makes the fiber optic connectors and data center interconnects that allow networking equipment to function at speeds that AI workloads need. The firm also now has a much deeper fiber optic portfolio after it acquired CommScope CCS (COMM).  This put Amphenol in a stronger position as data centers migrate from copper to fiber.

The second is Harsh Environment Solutions.  This serves aerospace, defense, and industrial applications. it is mostly used in matters of extreme conditions. Then the third is Interconnect and Sensor Systems, which serves automotive, medical, and industrial customers. Essentially, Amphenol runs three different sectors.

The company runs a decentralized model that allows business units to operate with a great deal of autonomy. This keeps the decision-making to the customer, which in turn speeds up product development cycles. 

What Q1 2026 Delivered 

Now let’s get into the numbers. I looked at the report, and my first thought was this is remarkable. The company’s revenue came in at a $7.6 billion, up 58% year-over-year in dollar terms and 33% organically.

The organic growth is something that we must take into consideration. It tells you how the main business is performing without the impact of things like acquisitions. Growing 33% organically in a single quarter is not something many companies achieve on a regular basis.

Adjusted EPS of $1.06 exceeded the consensus by more than 11%, which is the fourth consecutive quarter in which EPS has beaten expectations. The adjusted operating margin has also grown 380 basis points year-over-year to 27.3%. This is even more impressive if you take into account that the CommScope deal was margin dilutive right from the first day of closing. The fact that it has grown by almost four percentage points is proof that the operating leverage is built into the other part of the business.

Another very interesting data point of the quarter was the order book. Orders hit $9.4 billion, resulting in a book-to-bill ratio of 1.24:1. Every single end market, including IT datacom, defense, automotive, commercial aerospace, and industrial, all came in with a book-to-bill above one.

Free cash flow came in at $831 million for the quarter, which was 89% of its net income. The management expects a revenue of $8.1–$8.2 billion (43–45% YoY growth) and adjusted EPS of $1.14–$1.16 (41–43% YoY growth) for Q2 2026, which is wrapping up in a few days.

The CommScope Acquisition and Its Impact

In January 2026, Amphenol bought CommScope's Connectivity and Cable Solutions (CCS) business for almost $10.6 billion. This deal, by the way, left the company carrying $18.7 billion in total debt. This was detrimental to its balance sheet, but it was important.

The CCS acquisition expanded Amphenol's fiber optic capacity straight into the data center market. This came at a time when the demand for high-speed fiber connectivity in AI infrastructure is at an all time high. 
Data centers using the latest gen of AI training clusters need a lot of fiber optic interconnects and not just copper. And this is because the bandwidth demands of AI workloads is more than what copper can handle. 

In Q1, the CommScope faction brought in $871.5 million in revenue, though it ran at a small net loss due to inventory step-up charges.

Of course, there is a debt load but its not something that Amphenol cannot manage in my opinion. The company ended Q1 with $4.6 billion in cash and equivalents and a fully undrawn $3 billion revolving credit facility. The debt-to-FCF ratio sits at 4x, which means that the company could “theoretically” retire all of its debt in four years using free cash alone. The Altman-Z score of 5.99 also puts Amphenol comfortably in the financially healthy range with minimal bankruptcy risk.
The company was also able to return nearly $485 million to shareholders in Q1 through share buybacks and dividends. 

The China Tax Overhang: Headline Risk vs. Structural Risk

Let’s talk risks. One thing that caught my eye, and I’m sure other investors, was the effective GAAP tax rate, which increased to 42.7% from 22.7%. This was thanks to a $130 million accrual and an additional $160 million tax obligation in China.

This explains why the GAAP EPS of $0.72 looked weaker than the adjusted EPS of $1.06. I would separate this into two questions. The first is, is this a one-time hit or a recurring drag? The second is if these taxes in China represent a structural risk to the business.

On the first question, the tax accrual looks to be tied to an ongoing issue in China rather than a change in the tax policy for Amphenol globally. Management already guided for the elevated effective tax rate to continue all through 2026. However, starting from 2027, we should see normalization unless new updates come up.

For the second question, China is responsible for about 30% of Amphenol's revenue, which we cannot simply overlook. The tariff tensions or a deceleration in Chinese tech capex however could all create headwinds. This is a legitimate risk I will address more fully in the risk section.

Valuation: Building My Own Estimate

This is the part of the analysis I think you would find most useful, and also where I think the market is currently mispricing Amphenol. Let’s go through this one after the other.

Revenue Projections

For FY26, I expect the Communications Solutions segment to be around $17.5 billion in revenue. This includes a full year of CommScope contribution. This is me being conservative. Annualizing Q1 alone gets you to $18.1 billion, so $17.5 billon is putting into consideration that there might be some moderation in H2.

The Harsh Environment Solutions segment should also reach $7.0 billion. Interconnect and Sensor Systems should contribute around $6.5 billion. My total 2026 revenue estimate comes to $31 billion.

Let’s build the FY2027 projections. I made this estimate while applying deliberate deceleration. My assumption here is that growth slows from the pace we are seeing this year. 

So, with that in mind, I’m estimating that Communications Solutions would grow by 20% (well below the 47% seen in Q1). Harsh Environment grows 12% (defense spending remains high but decreases from 34%). Interconnect and Sensor also grow by 10%.

Communications Solutions; $17.5B × 1.20 = $21B 

Harsh Environment; $7.0B × 1.12 = $7.84B 

Interconnect and Sensor; $6.5B × 1.10 = $7.15B 

This brings the total to approximately $36B. 

The sell-side sits at around $34B and $35B, which brings my estimate modestly above consensus.

EV/Revenue SOTP

I’m assigning a bear multiple of 6x, in a base case, I would use a multiple of 8x, in a bull case, a multiple of 11x to the Communications Solutions segment. That would place the EV range between $126B and $231B (2027E: $21B). 

Harsh Environment Solutions ($7.84B), I would use a 4x bear, 6x base, 8x bull. This gives it an EV value of $31.36B to $62.72B. Interconnect and Sensor Systems ($7.15B), I would use 4x bear, 5x base, 6x bull. This brings the EV range to between $28.6B and $42.9B.

This brought the total EV range of $185.96B in the bear case, $250.79B at the base case, and $336.62B in the bull case.

If we subtract the net debt of $14.2 billion and divide by the 1.23 billion shares outstanding, we end up with a share price of $139.6 in the bear case, $192 in the base case, and $262 in the bull case.

EV/EBITDA Cross-Check

Let’s estimate the FY27 EBITDA. TTM EBITDA is currently at $8.5 billion. I am assuming it would see a 15% EBITDA growth into 2027, bringing it to $9.8 billion. In a bear case, I would use a multiple of 20x, in a base case, a multiple of 25x, and in a bull case, a multiple of 30x.

This brings the EV range between $196B and $294B. After debt subtraction and shares division, we end up with a share price between  $148 and $228.

Forward Earnings Check

If we annualize Q2 guidance midpoint ($1.15) and assume a steady H2 growth, I project that the FY26 adjusted EPS would come in at $4.60. For FY27, I’m assuming it would continue with another 25% EPS growth (which is way below the 68% achieved in Q1; again, this is my conservative view). This would bring us to an estimate of $5.75. 

At a forward multiple of 30x ( below the current trailing PE of 44x), the implied price would be $173.

Synthesis

From my projections in these methods, you can tell I may be somewhat  “too conservative” on multiples. I think I did not assign multiples that tell how well the Communications Solutions segment could do, thanks to the demand for AI.

Considering the forward earnings check and the base case targets of the two methods used, I am setting my price target to $183. Still conservative but I think very much achievable in the short term. Its Q2 earnings date has been set for July 29 and I expect it to act as a catalyst.

Risks: What Could Go Wrong

No honest analysis is complete without a serious discussion of risks. Here are the ones I consider most material.

1. China Concentration

With roughly 30% of revenue tied to China, Amphenol is exposed to deteriorating US-China trade relations in a way that many of its peers are not. Tariff escalation, technology export restrictions, or a slowdown in Chinese AI and industrial investment could meaningfully impair both revenue and margins in the Communications Solutions and Harsh Environment segments. This is not a theoretical risk — it is an active geopolitical variable that management is navigating in real time.

2. CommScope Integration Execution

The CCS acquisition was transformative in scale. At $10.6 billion, it is the largest deal in Amphenol's history. The company has a good track record with acquisitions, but larger deals carry larger integration risks. Key challenges include retaining CommScope's engineering talent, achieving the expected margin improvement trajectory, and ensuring that systems and customer relationships transfer cleanly. If integration runs slower than expected, the EPS accretion timeline shifts out.

3. AI Capex Cycle Sensitivity

Amphenol's Communications Solutions segment is now meaningfully tied to the AI infrastructure spending cycle of the major hyperscalers. If companies like Amazon, Google (GOOGL), and Microsoft slow their data center capex — whether due to a recession, a shift in AI strategy, or simply digestion of recent builds — orders in this segment would feel it quickly. The 1.24 book-to-bill provides some buffer, but it does not eliminate cycle sensitivity.

4. Valuation Premium

At a forward PE of around 34x and an EV/EBITDA of 23x, Amphenol is not cheap on a historical basis. The market is pricing in continued strong execution. Any miss — whether on revenue, margins, or guidance — could compress multiples quickly, given how elevated sentiment has become. The stock has run 94% over the past year, and mean reversion in multiples is a real risk even if the underlying business continues to perform.

5. Higher Tax Rate Persistence

Management has guided for an elevated effective tax rate through 2026. If the China tax determination leads to further adverse findings or a broader reassessment of Amphenol's global tax structure, the gap between GAAP and adjusted earnings could widen further, and adjusted EPS could come under pressure.

Conclusion: The Pick-and-Shovel Play The Market Keeps Overlooking

I want to come back to something I said at the beginning. Amphenol is not glamorous. No one puts a chart of connector sales on a CNBC segment. But when I look at what is actually required to build out AI infrastructure at the scale hyperscalers are spending — hundreds of billions of dollars globally — I keep arriving at the same answer: all of it needs to be physically connected.

The Q1 numbers confirmed what the thesis suggests. Record revenue, record orders, margin expansion despite a dilutive acquisition, and guidance that implies further acceleration. The CommScope deal, while adding debt, has positioned Amphenol in the fiber optic connectivity market precisely when demand is exploding. The China tax overhang is real but appears to be a finite, specific matter rather than a structural change in the business model.

My fair value estimate of $178 is conservative by design. I would rather be wrong on the upside than set an unrealistic target. The risk section is real — China, integration, and cycle sensitivity are all legitimate concerns that need to be monitored. But at current prices, I believe the market is underweighting the 2027 earnings power of a business that has now positioned itself as one of the most direct beneficiaries of the AI infrastructure buildout.

I rate APH a Buy.
