The main question: yearly earnings per share moved +74.0% while the share price moved +20.8%. ## What is the Amphenol share price today? Amphenol Corporation's share price was $84.19 at the close on 3 November 2026. It has been stalling near its high for 2 weeks. That is 11.6% above its average price over the last 200 trading days. Over the past 13 weeks it has done better than the S&P 500, and it has stayed ahead for 1 week in a row. In the last 52 weeks it traded between $62 and $87, and at that close it sat 88% of the way up from that low. Over the last 10 years the share price moved +487% while the S&P 500 moved +255%, so it is ahead of the index over that whole period. The chart above shows the 13-week comparison for every week. This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row. ## What dividend does Amphenol pay?

## Is Amphenol profitable? Amphenol Corporation earned $2.1 B of net profit in the Sep 2026 quarter, +63.7% on the same quarter a year earlier. That is the 12th quarter in a row of profit growth. Full-year FY25 profit was $4.3 B. Over 4 years profit has grown 28.0% a year on average. That is 20.1% of the quarter's revenue. The same quarter a year earlier earned $1.3 B. For the full year, FY25 profit was $4.3 B (+76.3% on the year before). Why profit moved: revenue changed +65.1% on a year earlier and the margin moved +2.2 percentage points. Most of the change came from keeping more of each sale. On average over the last four quarters, profit changed +53.2% and revenue +56.9%. Profit is growing slower than sales: rising costs are taking part of the growth. ## How much revenue does Amphenol make, and is it growing? Amphenol Corporation reported $10.2 B of revenue in the Sep 2026 quarter, +65.1% on the same quarter a year earlier. That is the 12th quarter in a row with growth on the year before. Over 4 years it has grown 20.7% a year on average. The last full year, FY25, came in at $23.1 B. The last four reported quarters add to $33.0 B. FY25 revenue was $23.1 B, +51.7% on the year before. Recent pace: the last four quarters grew +56.9% on average, against 20.7% a year over the longer run, so this year is growing faster than its own long-run rate. Is growth speeding up? Revenue over the last 12 months grew +57.6%, against +52.4% a year over the last 8 quarters (accelerating); profit over the last 12 months grew +55.4%, against +64.6% a year (rolling over). ## How much of every $100 of sales does Amphenol keep? Amphenol Corporation's operating margin was 29.7% in the Sep 2026 quarter, 2.2 percentage points higher than the same quarter a year ago. Its latest full-year margin is the highest it has ever reported. Across 5 years it has been between 19.9% and 26.2%. The latest quarter is above every full year in that period. Across 5 years it has been between 19.9% and 26.2%, and FY25's 26.2% is the highest of them. Why the margin moved: operating margin changed +2.2 percentage points on the year while gross margin changed +1.2 points. So the gain came mostly from costs below the gross margin, such as staff and overheads, measured against sales. As noted under valuation: when margins are at a record, every ratio built on profit looks better than usual, so a low multiple can mislead. ## Is Amphenol's profit turning into cash? Over the last 3 years, 123% of Amphenol Corporation's reported profit came in as cash from its operations, so the profit is backed by cash. In FY25 it brought in $5.4 B of operating cash against $4.3 B of profit. After $997 M of spending on assets, $4.4 B was left over as free cash. Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year. Why: the cash figure is clear, but the day counts behind it are not in our data, so we show it without guessing the reason. What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building. ## Where does Amphenol's cash go? Amphenol Corporation does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent $2.0 B on assets over the last 3 years. Averaged over those years that is 2.9% of FY25 revenue a year. Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn. Spending on assets: $2.0 B over the last 3 years. In short: the cash is going into new capacity, not getting stuck in the daily cycle. The question is whether the new capacity earns. ## What is Amphenol's P/E ratio, and how does it compare with its own history? Amphenol Corporation's P/E is 36.6×, about the lowest it has ever been. Its usual P/E (the middle reading) is 53.1×, over 4.6 years of weekly prices. This compares the share price with the company’s own past. It does not say what the business is worth. Keep one thing in mind: margins are the best this company has ever reported. A multiple that looks low against its own past can mislead when profit is at a record. If margins fall back, today's multiple is higher than it looks. Why the multiple is where it is: over the past year earnings per share moved +74.0% while the price moved +20.8%. Earnings did better than the price, which pulled the multiple down within its own range. Where the price move came from: over 3 years the price moved +25.7% a year; about +43.8% a year came from earnings growth and about −18.1 percentage points from the multiple (the market paying less). The split is approximate (price return minus earnings growth). It shows how much of the move came from the market paying a different multiple. In short: the multiple is low against its own past, so the earnings trend underneath matters more than the multiple. ## Is the Amphenol business getting better or worse? Amphenol Corporation's business is giving mixed signals. Growth is slowing from a very fast pace: profit growth has eased from +74.4% at its peak to +55.4%, but the business is still expanding, with ROCE rising at 32.7%. This is based on 12 quarters of 4 measures. Why it matters: when the lines disagree, each line above matters more than any single label. ## How much does Amphenol earn on its capital? Amphenol Corporation earned a ROE of 32% in FY25. That is up from a low of 23% in FY23. Its return on capital used (ROIC) is 12.1 percentage points above its cost of capital, so growth here adds value, not just size. It comes from a 18.6% net margin and 0.64× asset turnover (sales divided by assets). Why the return is what it is (FY25): a 18.6% net margin × 0.64× asset turnover × 2.68× leverage (assets divided by equity) ≈ 31.9% on equity. The margin does most of the work; borrowing is a big part of it. The key test, return on capital used minus the cost of capital: 22.7% − 10.6% = +12.1 percentage points. The 10.6% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. A gap this wide means each dollar put back into the business creates more than a dollar of value. The 22.7% ROIC above is the latest reading, as reported. The yearly chart below shows FY25 at 29.1%, and the quarterly chart works out each 12-month window from the quarterly figures, so the readings differ by date, not by method. ## Does Amphenol have too much debt? Amphenol Corporation has total debt of $17.9 B against shareholder equity of $17.3 B as of Sep 2026, so its debt is 1.03× its equity. Year by year, that ratio went from 0.79 in FY21 to 1.19 in FY25. Keep that borrowing in mind when reading the returns on this page. ## What is the Amphenol shareholding pattern? 1.1% of Amphenol Corporation's tradable shares are in short positions, which are bets that the price will fall, so very few traders are betting against this stock. At normal trading volumes, closing those positions would take about 2.3 days. US companies do not publish a quarter-by-quarter list of owners, so this page uses short interest instead. It is a single reading at one point in time; we do not have its history. Why it is at this level: the figure does not say who holds the short positions or why, so we show the level without guessing the story. ## How far is Amphenol from balance-sheet trouble? For Amphenol Corporation, the Z-score is 5.59. A Z-score above about 3 is safe and below about 1.8 signals danger, so this is well clear of danger. It estimates how far the balance sheet is from trouble; it is not a forecast of failure. Why it matters: a Z-score of 5.59 is well clear of the danger zone, so the balance sheet is not the risk here. ## How does Amphenol rank in its industry? 77.3 out of 100, rank 1 of 30 in Electronic Components, with 85% of the evidence available. Amphenol Corporation scores 77.3 out of 100 against the 30 companies it is compared with in Electronic Components, ranking 1. Earnings, capital efficiency and relative strength all agree. The open questions are about management, upcoming events and risks. The four parts add up to the total exactly: 23.6 + 20.8 + 14.6 + 18.3 = 77.3. This is the same number shown on the industry page; it is worked out once for the whole group and read here. What would change it: The score would fall if profit growth turns negative or margins stop improving while the share price lags its sector. ## Which companies is Amphenol compared with?

Missing figures are not scored as bad. They lower the confidence and pull the final score toward the middle. Relative strength counts only when the company has a reading for this week; with no reading, that factor is left out and its 20 points are shared across the other three in proportion. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led S&P 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step path the industry is placed on (basing, turning, breaking out, leader, fading, asleep), read from how many weeks running it has led S&P 500 and whether that lead is growing or shrinking. It describes where the share price stands, not the direction of earnings, and it is not a recommendation; it is left blank for a company whose weekly history is too short or too stale to read. The figures in this ranking come from the industry comparison: results through the Sep 2026 quarter, and the P/E at that quarter's end. The sections above use the latest weekly price, so a P/E or return there can differ a little from the one here. The stage words in this ranking (such as losing its lead or breaking out) describe the lead over the index, not the price phase in the price section.
