Amphenol just printed a quarter that, on a high level, looks almost unbelievable: net sales of $8.8 billion, up 55% year over year in U.S. dollars and 30% organically; GAAP diluted earnings per share of $1.37, up 59%; and orders of $10.7 billion for a book-to-bill of 1.23 to 1. Each of those numbers is a record. The growth is anchored on a single end market - information technology and data communications, which the company identifies as the source of "outsized organic growth, with particular strength in AI-related applications" - and on the largest acquisition in the company's history, the CommScope connectivity and cable solutions business that closed on January 9, 2026. Two distinct engines, both firing.
The picture becomes sharper, and the multiple becomes more interesting, when the quarter is decomposed. Adjusted operating margin reached 29.8% - the highest in the file - versus 25.6% a year ago. The 80-million-dollar International Emergency Economic Powers Act tariff recovery in the period inflated reported operating income by roughly 30 basis points; the underlying margin was still in the high-twenties. The 30% organic growth was led by a 42% organic jump in Communications Solutions, with the smallest segment, Interconnect and Sensor Systems, putting up 13% organic growth on what management describes as AI-related strength. The acquisition portion of the growth, 24% in U.S. dollars, is heavily CommScope, whose full-year 2026 sales guidance was raised during the quarter from $4.1 billion to $4.6 billion and whose expected 2026 adjusted-diluted-EPS accretion was raised from $0.15 to $0.30 per share.
Management was direct about what this quarter means. Chairman and Chief Executive Officer R. Adam Norwitt said the company "closed the second quarter of 2026 with record sales and Adjusted Diluted EPS, both exceeding the high end of our guidance," and called the operating-margin reading "outstanding." The capital return of $515 million in the quarter - $208 million of buybacks and $307 million of dividends - is a small fraction of the quarter's free cash flow of $1.2 billion and a clear statement about the management view of the share price. Third quarter guidance of $9.3 to $9.4 billion of sales, up 50% to 52% year over year, and adjusted diluted EPS of $1.40 to $1.42, up 51% to 53%, frames the next print. The market is paying roughly 39 times trailing-twelve-month adjusted earnings and 7.7 times trailing revenue for a company growing 30% organically with an acquisition pipeline that just delivered a doubling of the year-one EPS-accretion number. The bear case is not that the story is broken; the bear case is that the multiple is full.
