Income Statement Analysis: The Bottom-Line Duel
This income statement comparison reveals which company runs its financial engine with superior efficiency and sustainable growth momentum.
KLA Corporation Analysis
KLA’s revenue surged from 6.9B in 2021 to 12.2B in 2025, nearly doubling in five years. Net income followed, climbing from 2.1B to 4.1B. Gross margin holds strong at 62%, with net margin expanding to 33%. The latest year shows sharp EBIT growth of 41%, fueled by disciplined operating expenses and solid R&D investment, signaling robust operational momentum.
Teradyne, Inc. Analysis
Teradyne’s revenue peaked at 3.7B in 2021 but slid to 2.8B in 2024, reflecting a 9.7% decline over the period. Net income dropped 31% to 542M, with gross margin steady at 58% but net margin lower at 19%. Despite a modest 5% revenue growth last year, EBIT rose 16%, showing improved cost control, though overall profitability and growth remain challenged.
Margin Strength vs. Revenue Scale
KLA outpaces Teradyne in revenue scale and margin expansion, posting nearly three times the net income with superior profitability ratios. KLA’s consistent double-digit growth and margin improvement crown it the fundamental winner on operational efficiency and earnings power. Investors seeking growth backed by margin strength will find KLA’s profile more compelling.
Financial Ratios Comparison
These vital ratios act as a diagnostic tool to expose the underlying fiscal health, valuation premiums, and capital efficiency of the companies compared:

Efficiency & Valuation Duel: The Vital Signs
Financial ratios act as the company’s DNA, unveiling hidden risks and operational excellence that shape investment decisions in subtle ways.
KLA Corporation
KLA commands exceptional profitability with an 86.56% ROE and a robust 33.41% net margin, signaling operational dominance. Despite these strengths, its 29.34 P/E and 25.39 P/B ratios mark it as expensive. The modest 0.76% dividend yield suggests KLA balances shareholder returns with reinvestment in innovation and growth.
Teradyne, Inc.
Teradyne delivers solid profitability, with a 19.24% ROE and 19.23% net margin reflecting efficiency. Its valuation appears stretched, trading at a 36.93 P/E and a 7.11 P/B, higher relative to peers. The low 0.38% dividend yield highlights a focus on capital preservation, supported by a conservative debt profile and robust interest coverage.
Premium Valuation vs. Operational Safety
KLA’s extraordinary returns offset its premium valuation, while Teradyne offers a more balanced risk profile with solid efficiency and stronger balance sheet metrics. Investors favoring high operational prowess may lean toward KLA, whereas those prioritizing financial stability may find Teradyne’s profile more suitable.
Which one offers the Superior Shareholder Reward?
I see KLA Corporation (KLAC) delivers a stronger dividend yield near 0.76% with a moderate 22% payout ratio, well-covered by robust free cash flow. Its buyback program is intense, enhancing shareholder value. Teradyne, Inc. (TER) offers a lower 0.38% yield with a 14% payout but conserves cash for growth investments. TER’s buybacks are less aggressive. Historically in tech hardware, KLAC’s balanced dividend and buyback mix drives sustainable returns better than TER’s cautious approach. I favor KLAC for superior total shareholder reward in 2026.
Comparative Score Analysis: The Strategic Profile
The radar chart reveals the fundamental DNA and trade-offs of KLA Corporation and Teradyne, Inc., highlighting their financial strengths and vulnerabilities:
KLA shows superior profitability with top ROE (5) and ROA (5) scores but suffers from a weak balance sheet, reflected in its poor debt-to-equity (1) and price-to-book (1) scores. Teradyne offers a more balanced profile with moderate ROE (4) and strong asset efficiency (5), paired with a healthier debt position (4). However, Teradyne’s valuation metrics (P/E and P/B at 1 each) signal possible overvaluation risks. KLA relies heavily on operational efficiency, while Teradyne maintains steadier financial leverage.
Bankruptcy Risk: Solvency Showdown
KLA’s Altman Z-Score of 12.62 versus Teradyne’s 19.92 firmly places both firms in the safe zone, indicating strong long-term solvency in this cycle:
Financial Health: Quality of Operations
KLA’s Piotroski F-Score of 8 signals very strong financial health. Teradyne’s score of 5 is average, indicating some internal operational red flags compared to KLA:

These contrasts suggest differing strategic priorities around growth, risk, and capital allocation.
The Moat Duel: Analyzing Competitive Defensibility
A structural moat is the only true shield guarding long-term profits from relentless competitive erosion in dynamic markets:
KLA Corporation: Precision Process Control Moat
KLA’s moat stems from intangible assets and switching costs linked to its wafer inspection technology. It sustains a very favorable 27.5% ROIC premium over WACC with growing profitability. New semiconductor process innovations in 2026 could deepen its margin stability and market grip.
Teradyne, Inc.: Automation and Test Equipment Moat
Teradyne’s competitive edge lies in its system integration and cost advantage, contrasting KLA’s asset-heavy control moat. Despite a positive ROIC spread, its declining ROIC trend signals margin pressures. Expansion into industrial automation offers growth but also intensifies competitive risks.
Moat Strength: Process Control Precision vs. Broad Automation Reach
KLA’s wider and deepening moat outmatches Teradyne’s narrower, eroding advantage. KLA’s superior ROIC growth and margin resilience position it better to defend market share amid semiconductor complexity in 2026.
