Detailed Charts

Amphenol Performance

5-year trend showing revenue, gross profit, and net profit

FY2021 – FY2025

Amphenol's revenue grew 51.7% to $23.09B and net profit grew 76.2% to $4.27B YoY in FY2025, indicating strong business momentum.

Understanding Company Performance

Revenue is Amphenol's total income from operations. Gross Profit is revenue minus cost of goods sold — the higher it is relative to revenue, the stronger the company's pricing power. Net Profit is the bottom line after all expenses, taxes, and interest. Consistent growth across all three signals a healthy, expanding business. Compare with peers in the same sector.

Is Amphenol Profitable?

5-year trend showing gross, operating, and net profit margins

FY2021 – FY2025

Amphenol's net profit margin of 18.5% in FY2025 reflects good profitability, with operating margin at 25.9% and gross margin at 36.9%.

Understanding Profitability Margins

Gross Profit Margin (GPM) shows what percentage of Amphenol's revenue remains after direct production costs. Operating Profit Margin (OPM) factors in operating expenses like R&D and SG&A. Net Profit Margin (NPM) is the final profitability after all costs including interest and taxes. Stable or improving margins indicate pricing power and cost discipline.

FY2021 – FY2025

Amphenol's revenue grew 51.7% YoY in FY2025, with EPS growing 74.0%, strong top-line and bottom-line expansion.

Understanding Revenue & Earnings Growth

Revenue is Amphenol's total income from operations — the top line. Diluted EPS (Earnings Per Share) is net income divided by all shares that could exist if stock options, RSUs, and convertibles were exercised. Revenue shows how fast the business is growing; EPS shows how much of that growth reaches shareholders after all costs and dilution. Healthy companies tend to grow both in tandem; when revenue grows but EPS shrinks, margins are compressing. Use our stock screener to compare growth profiles across companies.

How to Read Quarterly Performance

Quarterly revenue and net income are Amphenol's most recent three-month results. Each bar shows net income nested inside revenue, since profit is the slice of revenue left after all costs; the taller the green portion relative to the blue, the more of each sales dollar reached the bottom line. A bar below zero is a quarterly loss.

For a long-term view, compare each quarter with the same quarter a year earlier (year-over-year), not with the previous quarter — sequential change is mostly seasonality (for many businesses the holiday quarter is always the biggest). Then watch the trend across several years: is year-over-year revenue growth accelerating or fading; is net income growing at least as fast as revenue (expanding vs compressing margins)? One quarter is noise — the multi-quarter trend is the signal.

Amphenol Share Price vs Book Value

Amphenol (APH) share price vs book value per share — FY2016 – FY2025

Understanding Share Price vs Book Value

Share Price is what the market pays per share of Amphenol. Book Value per Share (BVPS) is the company's net equity divided by diluted shares — the accounting floor if the company were liquidated today. When price tracks close to book value the market sees the company as a steady asset; when price runs far above book the market is paying up for expected future earnings. For banks, book value is the primary valuation anchor; for most other companies it's one signal among many.

Amphenol Free Cash Flow

5-year trend — cash generated after reinvestment

FY2021 – FY2025

Amphenol's free cash flow of $4.38B in FY2025 represents a 19.0% FCF margin — healthy cash generation supporting dividends, buybacks, or debt reduction.

Understanding Free Cash Flow

Free Cash Flow (FCF) is Amphenol's operating cash flow minus capital expenditure — the cash left over after maintaining and growing the business. Unlike net profit, FCF strips out non-cash items (depreciation, stock-based compensation) and includes actual cash spent on assets. Positive FCF means the company can pay dividends, buy back shares, reduce debt, or make acquisitions without raising capital. Consistently negative FCF signals the company is burning cash and may need external funding.

Debt-to-Equity

1.16

▲ from 0.71

Current Ratio

2.98

▲ from 2.37

Amphenol has a debt-to-equity ratio of 1.16, a current ratio of 2.98, interest coverage of 16.2x in FY2025, which indicate a well-capitalized balance sheet with comfortable debt levels.

Understanding Financial Health

Debt-to-Equity (D/E) measures how much debt the company carries relative to shareholder equity — lower means less leverage risk. Current Ratio divides current assets by current liabilities — above 1.0 means the company can cover short-term obligations. Interest Coverage is operating income divided by interest expense — higher means the company earns well above its debt payments. Together these three metrics reveal whether a company can weather downturns without financial distress.

Amphenol Shares Outstanding

Diluted share count per fiscal year — labels show year-over-year change

FY2021 – FY2025

Amphenol's diluted shares grew 1.1% YoY in FY2025, reflecting noticeable dilution often tied to SBC at growth-stage companies or capital raises.

Understanding Shares Outstanding

Diluted shares outstanding counts every share of Amphenol that could exist if all stock options, RSUs, and convertibles were exercised. A shrinking count signals buybacks (returning cash to shareholders by reducing the denominator of EPS). A growing count signals dilution — usually from stock-based compensation, secondary offerings, or stock-funded acquisitions. Routine 1–2% growth is typical at large-cap tech companies that pay employees in equity; sustained growth above 5% warrants a look at the cause.
