FLEX vs KEYS valuation comparison

In a direct FLEX vs KEYS valuation, Flex Ltd. appears to offer a more attractive entry point based on several key metrics. FLEX’s Price-to-Earnings (P/E) ratio stands at 57.59x, which is notably lower than Keysight Technologies’ P/E of 63.55x. While both valuations are on the higher side, FLEX presents a relatively cheaper earnings multiple. Similarly, looking at the Price-to-Book (P/B) ratio, FLEX is at 9.85x, closely comparable to KEYS at 9.81x, showing minimal difference in this specific asset-based valuation.

Perhaps more critically, the Discounted Cash Flow (DCF) analysis suggests that FLEX is less overvalued, indicating a -57.9% deviation from its DCF fair value compared to KEYS’s -72.9%. This substantial difference implies that, according to the DCF model, FLEX has a smaller valuation gap to close. Furthermore, FLEX boasts a significantly lower Debt-to-Equity (D/E) ratio of 0.11x, vastly outperforming KEYS’s 0.48x, which indicates a much healthier balance sheet and less financial risk. When considering FLEX vs KEYS fundamentals and valuation, FLEX exhibits a more favorable position from a valuation perspective, alongside stronger financial leverage.

FLEX vs KEYS growth comparison

When assessing the FLEX vs KEYS growth comparison, Flex Ltd. marginally edges out Keysight Technologies in terms of recent revenue expansion. FLEX reported a year-over-year revenue growth of 8.1%, slightly higher than KEYS’s 8.0%. While the difference is small, it positions FLEX as having slightly stronger top-line momentum, especially given its substantially larger revenue base of $27.91 billion compared to KEYS’s $5.38 billion. This indicates that FLEX is maintaining a solid growth trajectory even with a higher revenue scale.

However, the nature of growth should also consider profitability. While FLEX’s 8.1% revenue growth is commendable, its net margin is 3.15%, and EBITDA margin is 6.13%. In contrast, KEYS’s 8.0% revenue growth comes with significantly higher profitability, reflected in a net margin of 16.88% and an EBITDA margin of 24.75%. This suggests that while FLEX is growing its top line slightly faster, KEYS is converting its revenue into profit much more efficiently. Therefore, while FLEX has stronger revenue momentum, KEYS demonstrates a more capital-efficient growth model.

FLEX vs KEYS profitability

In the crucial area of FLEX vs KEYS profitability, Keysight Technologies (KEYS) exhibits a clear and substantial advantage across nearly all key metrics. KEYS’s net margin stands at an impressive 16.88%, which is significantly higher than FLEX’s 3.15%. This wide disparity indicates that KEYS is far more efficient at converting its revenue into net income, highlighting superior operational efficiency and cost management within its business model.

Similarly, KEYS’s EBITDA margin of 24.75% vastly outperforms FLEX’s 6.13%, further underscoring its ability to generate strong core operating profits before accounting for non-operating expenses. While both companies have N/A% for Return on Equity (ROE), Keysight’s Free Cash Flow (FCF) yield of 2.36% is also marginally better than Flex’s 2.11%. This stronger FCF yield suggests that KEYS is generating a slightly higher amount of cash relative to its enterprise value, providing more flexibility for investments, debt reduction, or shareholder returns. Overall, Keysight Technologies clearly generates more cash and demonstrates a superior profitability profile compared to Flex Ltd.

Analyst ratings: FLEX vs KEYS

Diving into the analyst ratings for FLEX vs KEYS, both companies generally receive positive sentiment, but with notable differences in their projected price targets. Flex Ltd. (FLEX) is covered by 25 analysts, with 72.0% issuing a “Buy” rating. The consensus price target for FLEX is $145.17, which implies a positive upside of +7.1% from its current price of $135.495. This suggests that analysts see room for appreciation in FLEX stock based on their models and expectations.

Keysight Technologies, Inc. (KEYS), while having fewer analysts covering it (15 in total), garners a higher percentage of “Buy” ratings at 80.0%. This indicates a stronger consensus among a smaller pool of analysts regarding its investment potential. However, the consensus price target for KEYS is $289.25, which represents a projected downside of -18.3% from its current price of $353.97. This conflicting view suggests that while analysts generally like KEYS, many believe it may be currently overvalued or has reached its near-term potential, making FLEX the stock with more analyst-projected upside.

Should I buy FLEX or KEYS stock in 2026?

Deciding whether should I buy FLEX or KEYS stock in 2026 depends heavily on an investor’s specific priorities. For growth-oriented investors, Flex Ltd. (FLEX) might appear slightly more appealing due to its marginally higher revenue growth rate of 8.1% compared to Keysight Technologies’ (KEYS) 8.0%. Although the difference is slight, FLEX operates on a significantly larger revenue base ($27.91B vs $5.38B), suggesting its ability to maintain growth at scale. However, it’s crucial to acknowledge KEYS’s much stronger profitability metrics, which indicate more efficient growth. This is not investment advice.

For value investors, the FLEX vs KEYS fundamentals and valuation comparison leans towards Flex. FLEX presents a lower P/E ratio of 57.59x against KEYS’s 63.55x, and a less severe DCF valuation implying -57.9% overvaluation compared to KEYS’s -72.9%. Additionally, FLEX has a remarkably lower Debt-to-Equity ratio of 0.11x versus KEYS’s 0.48x, pointing to a more robust financial structure and reduced leverage risk. These factors make FLEX appear “cheaper” and potentially offer a better risk-reward profile from a value perspective. This is not investment advice.

Regarding income investors, neither FLEX nor KEYS are suitable choices as both companies currently have a 0% dividend yield. For investors prioritizing regular income streams, exploring other options would be advisable. Ultimately, the choice between FLEX and KEYS in 2026 hinges on whether an investor prioritizes valuation and slightly higher revenue growth (FLEX) or superior profitability and a stronger analyst buy consensus (KEYS). This is not investment advice.
