Summary
Summary of the 8-K filed January 28, 2026. Cited figures are marked; the original filing is the authoritative source.
Amphenol (APH) reported record fourth-quarter and full-year 2025 results on January 28, 2026, with growth driven by strong organic demand (especially IT datacom) and a heavy acquisition program.
Q4 2025 net sales rose 49% year over year to $6.44 billiona (37% organic), and GAAP diluted EPS was $0.93, up 58%. Adjusted diluted EPS was $0.97, up 76%, and the adjusted operating margin reached 27.5%. For full-year 2025, net sales were $23.1 billion (up 52%, 38% organic), GAAP and adjusted diluted EPS were both $3.34, and the operating margin was 25.4% GAAP and 26.2% adjusted.
Free cash flow was $4.4 billionb for the year, and the company returned roughly $1.5 billion to shareholders. The filing also flags significant balance sheet and earnings-quality items. Total long-term debt rose to about $14.6 billion from $6.5 billion, reflecting acquisition funding, and the company closed the CommScope CCS business in January 2026.
Management guided Q1 2026 sales to $6.90c-$7.00 billion (up 43-45%) and adjusted diluted EPS to $0.91-$0.93, including roughly $900 million of sales and $0.02 of accretion from CCS. GAAP EPS guidance is only $0.81-$0.83 because about $135 million of acquisition-related costs are expected in the quarter. Q4 results also included a $100 million discrete tax accrual tied to a Chinese tax dispute, which the company says could ultimately reach $300 million.
For investors, the results show exceptional operating momentum and strong cash generation. The key watch items are the rising leverage from debt-funded acquisitions, the growing contribution from acquired revenue versus organic growth, the wide gap between GAAP and adjusted metrics, and the unresolved China tax exposure. This is a Item 2.02 furnishing of earnings information, so the release is not deemed filed under Section 18.

03—Questions
Frequently Asked Questions
How strong was Amphenol's growth in Q4 and full-year 2025?
Q4 2025 sales grew 49% in U.S. dollars to $6.44 billion, of which 37 points were organic. Full-year sales grew 52% to $23.1 billion, with 38% organic growth. Growth was broad across end markets, with exceptional organic growth in IT datacom and contributions from acquisitions, including Trexon and the Andrew Business.
Why are GAAP and adjusted EPS different, and how large is the gap in Q1 2026?
Adjusted EPS excludes acquisition-related expenses, excess tax benefits from stock compensation, and discrete tax items. For Q4 2025, GAAP EPS was $0.93 versus $0.97 adjusted. For Q1 2026, guidance implies GAAP EPS of $0.81-$0.83 versus adjusted EPS of $0.91-$0.93, mainly due to roughly $135 million of acquisition costs, most of which relate to the CCS business.
What does the CommScope CCS acquisition mean for 2026?
Amphenol closed the acquisition of CommScope's Connectivity and Cable Solutions business in January 2026. Management expects CCS to generate roughly $4.1 billion of full-year 2026 sales and add about $0.15 to 2026 adjusted diluted EPS. Q1 2026 guidance includes about $900 million of CCS sales and $0.02 of accretion.
Is the company's rising debt a concern?
Long-term debt rose to about $14.6 billion from $6.5 billion at year-end 2024, and current debt was $937 million. The increase funded acquisitions, including CCS, which closed after year-end. Cash of $11.1 billion at year-end, combined with $4.4 billion of free cash flow, provides meaningful liquidity, but investors should monitor leverage and interest expense, which rose to $368 million in 2025 from $217 million.
What is the China tax issue and what is the potential exposure?
Certain Chinese subsidiaries received notices from tax authorities challenging tax positions taken over up to eight years. Amphenol recorded a $100 million accrual in Q4 2025, which it considers its best estimate. The company says the potential range is $100 million to about $300 million, and it cannot estimate the timing of resolution.
