Amphenol Corporation (NYSE: APH) remains one of the standout performers in large-cap technology hardware as of December 3, 2025, powered by the AI datacenter boom, aggressive M&A and strong institutional demand – but also carrying a valuation that many analysts now describe as “stretched.”
Below is a detailed look at where Amphenol stock stands today, the most important news and filings around December 3, 2025, and how Wall Street forecasts and valuations stack up heading into 2026.
APH stock today: price, performance and basic stats
As of the latest quote on December 3, 2025, Amphenol Corporation stock trades around $139–140 per share, giving the company a market capitalization of roughly $170–171 billion. The shares are up modestly on the day, with a 24‑hour move of about +0.6%, after trading between approximately $137.4 and $140.4 in today’s session.
Over the last 12 months, APH has been on a tear:
- 52‑week range: about $56.45 to $144.37.
- 2025 year‑to‑date total return: roughly +100%, with Yahoo Finance showing about +102% YTD total return versus the S&P 500 benchmark. [1]
On commonly used valuation measures:
- Trailing P/E: around 52x earnings, based on current share price and trailing twelve‑month EPS.
- Tickeron’s fundamental screeners show P/E around 46x, price‑to‑book about 13.6x (vs ~5.3x industry average) and price‑to‑sales ~8.4x (vs ~3.2x industry), underscoring a meaningful premium to the broader electronic components group. [2]
Put simply, Amphenol is priced as a high‑growth, high‑quality compounder, and investors are clearly paying up for that profile.
Record Q3 2025 earnings: AI and connectivity drive a step‑change
The core fundamental story behind APH’s run is explosive revenue and earnings growth, driven by AI infrastructure, high‑speed connectivity and recent acquisitions.
In its Q3 2025 earnings release on October 22, Amphenol reported: [3]
- Sales of $6.2 billion, up 53% year over year in U.S. dollars and 41% organically versus Q3 2024.
- GAAP diluted EPS of $0.97, up 102% from a year earlier.
- Adjusted diluted EPS of $0.93, up 86% year over year.
- Operating and free cash flow of $1.5 billion and $1.2 billion, respectively.
- Operating margin (GAAP and adjusted) of 27.5%, a record for the company.
A Reuters write‑up highlighted how the Communications Solutions segment, which includes high‑speed cables and antennas for data centers and communications networks, generated about $3.31 billion in Q3 sales, up 96% year over year, as AI‑related infrastructure spending continued to surge. [4]
Management also emphasized:
- “Exceptional” organic growth in the IT datacom market (AI data centers, cloud, high‑speed networking). [5]
- Strong contributions from its acquisition program, including newly acquired businesses focused on communications infrastructure and sensors. [6]
These results not only beat Wall Street estimates but also set the tone for the bullish guidance that followed.
Guidance: strong Q4 and full‑year 2025 outlook
Alongside Q3 results, Amphenol issued above‑consensus guidance for the rest of 2025: [7]
- Q4 2025 revenue: expected between $6.0 and $6.1 billion, ahead of analyst expectations around $5.7 billion.
- Q4 2025 adjusted EPS:$0.89–0.91, above consensus near $0.80 at the time of the announcement.
- Full‑year 2025 revenue:$22.66–$22.76 billion, implying ~49–50% growth over 2024.
- Full‑year 2025 adjusted EPS:$3.26–3.28, representing ~72–74% EPS growth versus 2024.
This is the earnings and growth backdrop that current analyst forecasts and December 3 commentary are reacting to.
Big deals: CCS, Trexon and earlier OWN/DAS – building an AI‑era empire
A second major driver of sentiment around APH is its aggressive M&A strategy in communications and harsh‑environment interconnects.
CommScope’s CCS business – a $10.5 billion AI‑heavy bet
On August 4, 2025, Amphenol announced a definitive agreement to acquire CommScope’s Connectivity and Cable Solutions (CCS) business for $10.5 billion in cash. [8]
Key points:
- CCS is expected to generate ~$3.6 billion in 2025 sales with EBITDA margin around 26%. [9]
- The acquisition expands Amphenol’s fiber‑optic interconnect capabilities in:
- IT datacom, particularly AI and other data center applications.
- Communications networks (broadband, telecom).
- Building infrastructure connectivity in industrial markets. [10]
- Management expects the deal to be accretive to diluted EPS in the first full year after closing (expected in the first half of 2026). [11]
This is widely viewed as a transformational transaction that cements Amphenol as a core picks‑and‑shovels provider for the AI datacenter build‑out.
Trexon – scaling defense‑focused cable assemblies
On August 18, 2025, Amphenol announced a $1 billion cash acquisition of Trexon, a high‑reliability interconnect and cable assemblies provider focused primarily on the defense market. [12]
The company expects Trexon to deliver:
- ~$290 million in 2025 sales with ~26% EBITDA margins;
- Integration into the Harsh Environment Solutions segment;
- EPS accretion in the first year post closing (closing expected by the end of Q4 2025). [13]
OWN & DAS and Lifesync – earlier 2025 deals that are already contributing
Back in February 2025, Amphenol closed the acquisition of CommScope’s Outdoor Wireless Networks (OWN) and Distributed Antenna Systems (DAS) businesses. The company expects these to generate roughly $1.3 billion of 2025 sales and to be about $0.06 accretive to 2025 EPS, excluding acquisition‑related costs. [14]
On the same day, Amphenol also closed the acquisition of Lifesync, a medical interconnect company with ~$100 million in annual sales, bolstering the Harsh Environment Solutions segment. [15]
Taken together, these deals significantly expand Amphenol’s footprint in AI data centers, communications infrastructure, defense and medical devices, and they feature prominently in current analyst and media commentary.
Fresh headlines on December 3, 2025: institutions buy, insiders sell
Most of today’s APH‑related headlines revolve around institutional money flows, insider activity and updated analyst context.
1832 Asset Management massively boosts its stake
A new MarketBeat article dated December 3, 2025 reports that 1832 Asset Management L.P. increased its Amphenol stake by over 8,300% in Q2, to about 1.80 million shares, worth roughly $178 million and representing around 0.15% of the company. [16]
The same piece notes that:
- Major long‑only investors such as Vanguard, Geode Capital, Norges Bank, T. Rowe Price and Franklin Resources also hold sizeable positions.
- Overall, about 97% of APH’s shares are owned by institutional investors and hedge funds. [17]
Pinkerton Wealth and Lido Advisors add to positions
Two additional institutional flow stories, also published December 3, 2025, highlight incremental buying: [18]
- Pinkerton Wealth LLC opened a new APH position of 29,842 shares in Q2, valued at just under $3 million.
- Lido Advisors LLC boosted its stake by 9.9%, purchasing 8,756 shares to bring its holding to 97,048 shares, worth roughly $9.6 million.
Both articles stress that institutional ownership hovers around 97%, reinforcing the idea that APH is deeply embedded in professional portfolios. [19]
Insider selling: multi‑month wave plus a new Rule 144 notice
There’s a counter‑trend on the insider side.
The same MarketBeat notes summarize that over the last three months, insiders – including senior executives like Luc Walter and CFO Craig Lampo – have sold roughly 983,000 shares, with aggregate proceeds around $137 million. [20]
Separately, a Rule 144 filing reported by StockTitan on December 2, 2025 shows that insider Peter John Straub plans to sell 132,000 shares of APH after exercising stock options, on or about December 2, via Morgan Stanley. The same individual sold 88,000 shares in September, bringing total disclosed sales to 220,000 shares over three months – still a small fraction of the ~1.22 billion shares outstanding. [21]
The filing explicitly states that the seller does not know of any material adverse non‑public information, and the commentary classifies the transaction as a routine liquidity event related to stock‑option exercises. [22]
Short summary for December 3 flows
- Net message:
- Smart‑money institutions are still accumulating APH, often citing its AI and connectivity exposure.
- Insiders have been significant net sellers in recent months, which some investors may view as a valuation signal, others as normal diversification after a major run‑up.
Dividend hike and shareholder returns
On the capital‑returns front, Q3 brought a big dividend surprise.
Amphenol’s board approved a 52% increase in the quarterly dividend, from $0.165 to $0.25 per share, payable January 7, 2026 to shareholders of record on December 16, 2025. [23]
At today’s share price near $139–140, that implies:
- Annualized dividend: $1.00 per share.
- Forward yield: roughly 0.7%, very much in line with current analyses. [24]
In Q3 alone, Amphenol:
- Repurchased 1.4 million shares for $153 million, and
- Paid $201 million in dividends, returning roughly $354 million to shareholders in the quarter. [25]
This reinforces the company’s positioning as a growth + dividend story: modest current yield, but robust dividend growth and consistent buybacks.
Analyst ratings and price targets as of early December 2025
Current Street sentiment on APH is broadly positive, though there is some divergence on upside vs downside from here.
Consensus ratings
- StockAnalysis.com aggregates views from 11 analysts and reports an average rating of “Strong Buy”, with an average 12‑month price target of $142.73 – about 2–3% upside from the latest price. [26]
- MarketBeat sees a “Moderate Buy” based on 13 analysts, with 10 Buy ratings and 3 Holds, and a consensus target around $131.54 – implying mid‑single‑digit downside from today’s level. [27]
In other words, almost everyone likes the business, but some data sets suggest the stock may be ahead of its fair value after a 100%+ run in 2025.
Key recent target changes cited across December 3 coverage
Recent MarketBeat pieces and December commentary highlight several notable target hikes: [28]
- JPMorgan: target raised to $160, “overweight”.
- Bank of America: upgraded APH to “buy” with a $150 price objective.
- UBS: target around $152, “buy”.
- Goldman Sachs: target near $154, with a “buy” call.
- Robert W. Baird: price objective in the high‑$130s with “outperform”.
These higher targets cluster in the $140–160 range, supporting the idea that upside exists, but largely if the AI datacenter boom, M&A integration and margin expansion continue to deliver.
December 3 feature articles: bullish but valuation‑conscious
Several fresh analysis pieces dated December 3, 2025 synthesize the story investors are debating now.
TS2.Tech: “AI Datacenter Boom Meets Stretch Valuation”
A long‑form article from TS2.Tech, published December 3, 2025, explicitly frames Amphenol as a “boring” but critical data‑center growth stock whose fundamentals are exceptional but whose valuation leaves less margin for error. TS2 Tech
Key takeaways from that piece and its referenced sources:
- Fundamentals
- Street view
- Across platforms like StockAnalysis, MarketBeat and Simply Wall St, APH is commonly described as having an “outstanding track record”, strong balance sheet, and high‑quality earnings, with most 12‑month price targets clustered around $140–$150 and some outliers up to $160+. [31]
- Risks highlighted
- Valuation risk: APH trades at a premium to peers on P/E, P/B and P/S; if AI demand or cyclically sensitive end markets slow, the multiple could compress. TS2 Tech+1
- Integration and leverage: The $10.5 billion CCS deal and the large senior notes offerings used to finance it introduce integration and financing risk if synergy targets slip or rates remain elevated. [32]
The TS2 analysis ultimately concludes that APH remains very attractive for long‑term investors who believe in a durable AI and connectivity “super‑cycle”, while short‑term, valuation‑sensitive traders may want to be more cautious. TS2 Tech
Zacks: “Up ~90% in a year – still a buy for 2026?”
A Zacks‑authored piece syndicated via TradingView notes that Amphenol shares are up around 90% over the past 12 months and currently carry a favorable Zacks Rank, reflecting upward‑revised earnings estimates. [33]
From the excerpted consensus data:
- The 2025 EPS estimate has been revised higher in recent weeks and implies very strong growth vs. 2024.
- 2026 estimates are also trending upward, suggesting that analysts expect growth to continue beyond the current AI capex cycle, not just in it. [34]
However, Zacks also acknowledges the extended valuation, which is typical for the “Quality‑Growth” category into which APH now firmly falls.
Tickeron AI and other quant views
Quant‑driven platforms like Tickeron rate Amphenol’s earnings growth and price growth metrics favorably, while generally describing the company as fairly valued relative to its high‑growth peer group (despite being optically expensive versus the broader market). [35]
How APH’s valuation stacks up now
Putting the various data points together:
- Absolute valuation:
- Relative to growth:
- Street targets:
- Most price targets cluster between $140 and $150, around where the stock is already trading, with a handful at $160+ for more bullish houses. [40]
Investors reading today’s research are repeatedly confronted with the same trade‑off: exceptional business momentum vs. a rich entry price.
Key risks investors are watching
The December 3 commentary and recent research repeatedly highlight several risk themes:
- Valuation compression
- If AI spending or broader industrial demand slows, APH’s premium multiple could de‑rate, even if earnings stay healthy. TS2 Tech+1
- Cyclical end‑market exposure
- Amphenol sells into auto, industrial, communications networks and aerospace – all of which can see sharp swings in demand during economic slowdowns. [41]
- Acquisition integration and balance sheet leverage
- The $10.5B CCS acquisition and ongoing M&A program increase complexity and interest expense; poor integration or slower synergy realization could pressure margins and free cash flow. [42]
- Competition in high‑speed connectivity
- Competitors such as TE Connectivity and newer AI‑centric players are aggressively targeting the same high‑growth markets, including high‑speed data center interconnects. TS2 Tech
- Insider selling optics
- While recent insider sales are small relative to total shares and often tied to option exercises, the scale and timing after a huge rally can nonetheless be a psychological overhang for some investors. [43]
What to watch next for Amphenol stock
Looking beyond December 3, 2025, the main catalysts and checkpoints for APH include:
- Q4 2025 earnings (early 2026)
- Whether Amphenol can hit or beat its ambitious guidance of $6.0–6.1B in revenue and $0.89–0.91 in adjusted EPS. [44]
- Closing and integration of Trexon and CCS
- Markets will focus on regulatory approvals, funding mix, synergy commentary and early evidence that these large deals can be integrated without eroding margins. [45]
- AI and datacenter capex trends
- Any sign that hyperscale and enterprise AI capex is re‑accelerating or slowing will likely move APH, given its deep tie‑in to that ecosystem. [46]
- Dividend and buyback policy
- The new $0.25 dividend and continued repurchases support total return; future dividend growth will be a key metric for dividend‑growth investors. [47]
- Further institutional and insider activity
- Additional 13F filings and Form 4 / 144 filings will give clues about whether institutional accumulation and insider selling trends persist. [48]
Bottom line
As of December 3, 2025, Amphenol Corporation stock sits at the intersection of two powerful stories:
- A fundamentally outstanding business enjoying record growth, massive free cash flow, accretive acquisitions and a growing dividend, all riding the structural tailwinds of AI, connectivity and defense.
- A valuation that reflects those strengths and then some, with P/E and other multiples well ahead of market averages, significant recent insider selling and somewhat mixed signals on near‑term upside from consensus price targets.
For investors following APH via Google News or Discover, the key questions going forward are:
- Will AI‑driven and infrastructure demand remain strong enough to justify today’s premium multiple?
- Can management successfully integrate CCS, Trexon and other acquisitions while preserving 25%+ operating margins?
- Does a 0.7% yield and rapid dividend growth offset the risk of multiple compression?
