Amphenol reported a sharp rise in third-quarter sales on October 28, 2026. But the most useful number for understanding the quarter may be the gap between its reported growth and its organic growth: the two measures describe different parts of how a company expands.
In its company earnings release, distributed at 8:00 a.m. U.S. Eastern time, Amphenol said sales reached $10.2 billion, up 65% in U.S. dollars from a year earlier. Organic sales grew 37%. All dollar amounts here are U.S. dollars. The company also reported $12.2 billion in orders and a book-to-bill ratio of 1.19.
Reported and organic growth answer different questions
Reported sales measure the total revenue appearing in the quarter. Organic growth attempts to isolate growth in comparable operations by adjusting for items such as acquisitions and currency, using the company’s definition. Reading both measures helps separate expansion of an existing business from changes in the corporate portfolio.
A company that buys another business can legitimately report higher total revenue. But adding the purchased company’s sales does not, by itself, show how quickly the original business grew. Conversely, organic growth does not capture the full effect of an acquisition on the size of the combined business. Investors need both views and the reconciliation in the release.
Here, 37% organic growth is still substantial. The spread between that figure and the reported rate is a reason to investigate acquisitions and currency effects; it should not be interpreted as an exact measure of acquisition contribution without checking the company’s calculation.
What is book-to-bill?
The company’s reported book-to-bill ratio compares orders booked with sales billed over a period. A reading above one means orders exceeded sales in that period. It can suggest future demand, but it is not a promise that every order becomes a profitable sale on the same schedule.
Orders can be rescheduled or affected by customers’ purchasing plans. A supplier expanding capacity also faces the risk of investing ahead of demand. The measure is most useful alongside backlog terms, customer concentration and subsequent deliveries, rather than in isolation.
Profit and cash are not the same measure
Amphenol reported GAAP diluted earnings per share of $0.79 and adjusted diluted EPS of $0.80. Adjusted figures exclude specified items and should be read with the reconciliation to GAAP. The company also reported $2.1 billion of operating cash flow and $1.6 billion of free cash flow.
Free cash flow is not identical to accounting profit: timing of payments and investment in equipment can create differences. Strong cash generation can support investment or distributions, but one quarter may benefit from timing that does not persist.
Dividend and buybacks
Amphenol announced a higher quarterly dividend and a new share-repurchase authorization. An authorization permits repurchases under its terms; it does not guarantee that the company will buy the maximum amount. Buybacks can reduce the share count, but their effect on value also depends on the price paid and the company’s other uses for cash.
For a reader comparing AI infrastructure suppliers, our discussion of Corning’s optical business illustrates a different part of the physical network. Similar exposure to a broad theme does not make the companies’ products, financials or risks interchangeable.
The longer-term test
The questions are whether organic demand remains strong, whether acquired businesses are integrated successfully and whether margins and cash generation hold up as the business invests. A headline growth rate describes the past quarter; the durability and price of that growth remain open questions.
