Amphenol Posts 65% Sales Growth, 37% Organic Growth in Q3 2026, Unveils New $4 Billion Buyback

Amphenol Corporation reported record third-quarter 2026 results on October 28, 2026, with sales climbing 65% year over year and organic growth of 37%, according to the company's earnings release distributed via Business Wire and reported by FinancialContent and Stock Titan. Alongside the results, Amphenol's Board of Directors authorized a new three-year, $4 billion stock repurchase program.

Record Quarter, Higher Profitability

Per the company's release, GAAP Diluted EPS reached $0.79, up 61% from the prior-year quarter, while Adjusted Diluted EPS of $0.80 rose 74%. Stock Titan's reporting on the release put quarterly sales at a record $10.2 billion. The release also disclosed orders of $12.2 billion, producing a book-to-bill ratio of 1.19:1 — a ratio above 1.0, which by definition means orders booked in the quarter exceeded shipments billed. The company did not characterize that ratio beyond reporting it.

What Drove the Organic Growth

CEO R. Adam Norwitt, quoted in the Business Wire release, attributed the 65% sales increase to "strong organic growth in most of our end markets, including continued exceptional organic growth in the IT datacom market, as well as contributions from the Company's acquisition program." The release did not break out organic growth numerically by individual end market such as automotive or industrial, leaving IT datacom as the only market singled out within an otherwise broad-based advance. Seeking Alpha's market-news summary of the report echoed this characterization, citing "strong organic growth across end markets, exceptional growth in IT datacom, acquisitions, technological innovations, and business diversification" as the drivers of the revenue and profit gains, as noted in its coverage.

Acquisitions also contributed, according to the company's release. Amphenol closed its purchase of Empire Electronics, a Michigan-based manufacturer of complex interconnect assemblies for the Automotive market with a focus on automotive lighting-related products, which the release said is expected to generate approximately $320 million in full-year 2026 sales. Separately, the company signed a definitive agreement to acquire AdvancedPCB, a Colorado-based U.S. manufacturer of high-technology printed circuit boards for the Defense and Industrial markets, expected to have approximately $270 million in full-year 2026 sales and to be included in the Harsh Environment Solutions segment post-closing.

The New $4 Billion Buyback

The Board's new repurchase authorization, approved October 27, 2026, spans three years and becomes effective January 1, 2027, per the company's release. The disclosed materials did not specify the size or remaining capacity of any prior buyback authorization, so a direct comparison to earlier programs cannot be drawn from the available reporting.

Forward Guidance

Per the company's release, Amphenol expects fourth-quarter 2026 sales of $10.3 billion to $10.5 billion, roughly a 60% year-over-year increase, with Adjusted Diluted EPS of $0.81 to $0.83. Full-year 2026 sales guidance is $36.9 billion to $37.1 billion, also an approximately 60% increase, with Adjusted Diluted EPS of $2.82 to $2.84. The company also raised its 2026 outlook for the CommScope business it has integrated, now expecting $5.1 billion in full-year sales and $0.18 of Adjusted Diluted EPS accretion, up from prior expectations of $4.6 billion and $0.15.

Interpretively, the 1.19:1 book-to-bill ratio and the raised CommScope contribution suggest management sees demand momentum continuing into the fourth quarter, though this remains our reading of the disclosed order and guidance figures rather than a projection stated by the company.

Bottom Line

Amphenol's third quarter combined broad-based organic growth, led by IT datacom demand, with acquisition contributions from Empire Electronics and a pending AdvancedPCB deal, alongside a new $4 billion capital return commitment set to begin in 2027. Guidance for the fourth quarter and full year points to continued growth, according to the company's own figures, though investors should note that the specific scale of prior buyback programs was not detailed in the available reporting for direct comparison.
