About
Amphenol designs and makes connectors, cables, antennas and sensors. Its products carry power and data inside AI servers and data centers, cars, airplanes, factory equipment, phones and communication networks. It reports three segments: Communications Solutions, Harsh Environment Solutions, and Interconnect and Sensor Systems. Communications Solutions is the largest, with removed: $5.4 added: $6.6 billion of the removed: $8.8 added: $10.2 billion of sales in removed: Q2 added: Q3 2026. The IT datacom market, which includes AI data centers, gave $3.8 billion of sales in Q2 2026. Amphenol grows partly by buying companies. In Q1 2026, it completed the purchase of CommScope's Connectivity and Cable Solutions (CCS) business, and it expects this business to bring about removed: $4.6 added: $5.1 billion of sales in 2026. added: In September 2026, it bought Empire Electronics, a maker of interconnect assemblies for cars, and in October 2026 it had agreements to buy three more companies. Amphenol did a 2-for-1 stock split in September 2026, and the per-share figures in this profile are adjusted for the split.
Thesis
Amphenol trades at a discount because investors fear that its growth depends on AI data center spending that can slow. In Q2 2026, IT datacom sales grew 63% on an organic basis to $3.8 billion, about 43% of total sales. If the large cloud companies cut their AI budgets, these orders can fall fast. Investors also watch the cost of the CommScope CCS purchase, which Amphenol paid for with cash and new debt. Debt was removed: $18.8 added: $17.9 billion at removed: June added: September 30, 2026, against removed: $5.4 added: $5.3 billion of cash and short-term investments. removed: Part added: Amphenol also keeps buying companies: the four purchases it announced in its Q3 2026 report cost about $1.6 billion in total.

For the gap to close, orders must removed: stay added: keep staying above sales, removed: as they did with a book-to-bill of 1.23 in Q2 2026, Amphenol must reach its removed: Q3 added: Q4 2026 guidance of removed: $9.3 added: $10.3 to removed: $9.4 added: $10.5 billion of sales and removed: $0.70 added: $0.81 to removed: $0.71 added: $0.83 of removed: split-adjusted adjusted EPS, and growth must spread beyond IT datacom to markets such as defense, industrial and automotive. removed: CommScope must also reach its expected 2026 sales of $4.6 billion. The removed: first added: next test is the removed: Q3 2026 report on October 28, 2026. The second test is the Q4 2026 report, expected in late January 2027, with the first view of 2027. If orders stay strong, the gap can close over the next two to four quarters. The main risk is a cut in AI data center spending that reduces orders.
Risks
IT datacom sales were $3.8 billion in Q2 2026, about 43% of total sales, and grew 63% on an organic basis from AI demand. A small number of large cloud companies drive this spending. If they cut their AI budgets, orders can fall fast. Amphenol paid about $10.6 billion, net of cash acquired, for acquisitions in Q1 2026, mainly CommScope CCS, and issued $3.6 billion of new debt. Debt was removed: $18.8 added: $17.9 billion at removed: June added: September 30, 2026. added: In October 2026, Amphenol said that four more purchases cost about $1.6 billion in total.

New tariffs on parts that Amphenol makes outside the US can raise its costs. added: Tax costs rise. In the first nine months of 2026, Amphenol added: recorded $290 million of tax charges for China, after unfavorable decisions by Chinese tax authorities and a review of tax rates for earlier years. It raised its adjusted tax rate to 27.0%. Amphenol sells into cyclical markets, such as automotive, industrial and mobile devices. A slowdown in these markets can lower sales when AI growth slows too.
