AAOI vs VECO: key metrics side by side

Full side-by-side comparison of AAOI and VECO across valuation, profitability, growth and analyst sentiment. Data updated 2026-05-11.

AAOI vs VECO valuation comparison

The AAOI vs VECO valuation comparison reveals distinct profiles for these two technology stocks. Applied Optoelectronics (AAOI) currently trades with a P/E ratio of -261.13x, which is a direct reflection of its current unprofitability. A negative P/E ratio indicates that the company is losing money, making it challenging to use this metric for traditional valuation comparisons against profitable companies. Investors interested in AAOI must therefore look beyond earnings and focus on its growth potential and path to profitability. In contrast, Veeco Instruments (VECO) reports a P/E ratio of 155.27x. While significantly high, suggesting that substantial future growth is already priced into the stock, it at least indicates a positive earnings stream, which AAOI currently lacks. This P/E ratio, while elevated, points to a market expectation of continued strong performance for VECO.

Moving to other valuation metrics, VECO appears to offer a more reasonable position. Its Price-to-Book (P/B) ratio stands at 4.06x, which is considerably lower than AAOI’s P/B of 10.23x. This suggests that VECO’s stock price is more closely aligned with its underlying asset value compared to AAOI. Furthermore, when evaluating the intrinsic value through Discounted Cash Flow (DCF) models, both companies appear overvalued at their current prices. AAOI’s DCF analysis points to a staggering -124.2% implied downside, suggesting its current price of $148.94 is far above its calculated fair value. VECO’s DCF, while also indicating an overvaluation, shows a less severe implied downside of -86.8% from its current price of $59.42. Therefore, while both stocks present valuation challenges, VECO appears relatively less stretched on a P/B basis and by DCF metrics in this AAOI vs VECO valuation analysis.

AAOI vs VECO growth comparison

In the AAOI vs VECO growth comparison, Applied Optoelectronics (AAOI) clearly stands out with its impressive top-line performance. The company reported a remarkable year-over-year revenue growth rate of +82.8%. This significant surge suggests strong demand for AAOI’s products and services, potentially driven by new market opportunities, successful product launches, or increased market share. Such high growth rates often attract growth-oriented investors who prioritize expansion and future market dominance, even if current profitability is not yet established. This momentum could be a key indicator of the company’s potential to scale operations and eventually achieve sustainable earnings.

On the other hand, Veeco Instruments (VECO) experienced a revenue growth of -7.4% year-over-year. This decline indicates that VECO is facing headwinds, which could stem from market slowdowns, increased competition, or shifts in customer demand within its sector. While a negative growth rate is concerning, it doesn’t necessarily mean a company is in long-term decline; it could be part of a cyclical industry or a temporary setback. However, when directly comparing the two, AAOI undeniably demonstrates stronger momentum and a more aggressive growth trajectory. For investors focused on robust revenue expansion and market penetration, AAOI presents the more dynamic growth story, whereas VECO’s recent performance suggests a more challenging immediate outlook for top-line expansion.

AAOI vs VECO profitability

When assessing AAOI vs VECO profitability, Veeco Instruments (VECO) clearly holds a superior position. VECO consistently demonstrates its ability to convert revenue into profit, reporting a healthy net margin of 3.53% and a robust EBITDA margin of 8.76%. These positive margins indicate efficient operations, effective cost management, and a strong underlying business model that generates real earnings. Such profitability metrics are crucial for long-term sustainability and provide a buffer against economic downturns or unexpected operational challenges. For investors seeking companies with proven financial health, VECO’s consistent profitability is a significant advantage.

Conversely, Applied Optoelectronics (AAOI) is currently operating at a loss, evidenced by its negative net margin of -8.55% and a negative EBITDA margin of -3.39%. This unprofitability means that AAOI is not yet generating enough revenue to cover its operational costs, including production, sales, and administrative expenses. Furthermore, in terms of cash generation, VECO boasts a positive Free Cash Flow (FCF) yield of 1.18%, meaning it is producing cash from its operations after capital expenditures. AAOI, however, has a negative FCF yield of -2.0%, indicating that it is consuming cash to fund its operations and growth, which can be a concern for its financial stability without external funding. While the Return on Equity (ROE) figures are not available for either company, the stark difference in margins and FCF yield firmly positions VECO as the more profitable enterprise in this comparison.

Analyst ratings: AAOI vs VECO

In the realm of analyst sentiment for AAOI vs VECO, Veeco Instruments (VECO) appears to have a slight edge. A larger pool of analysts, 36 in total, covers VECO, with 52.8% of them issuing a “Buy” rating, resulting in a collective “Buy” consensus. This broader coverage and higher percentage of positive recommendations suggest a greater level of confidence in VECO’s prospects among financial professionals. Applied Optoelectronics (AAOI), while also maintaining a “Buy” consensus, has a lower percentage of “Buy” ratings at 43.8% from its 16 covering analysts. This difference indicates that while both companies are viewed favorably, VECO garners stronger endorsement from the analyst community.

However, when delving into price targets, both stocks face significant projected downsides according to analyst consensus. For AAOI, the average target price is $74.5, representing a substantial -50.0% decrease from its current price of $148.94. This implies that analysts believe AAOI is currently trading well above its fair value. VECO’s consensus target price is $34.75, which also suggests a considerable -41.5% downside from its current price of $59.42. While both figures are concerning for current investors, VECO’s implied downside is notably less severe than AAOI’s. This further reinforces the perception that analysts, despite projecting price corrections for both, see VECO as a relatively safer bet or less overvalued in the current market environment than AAOI.

Should I buy AAOI or VECO stock in 2026?

For growth investors eyeing aggressive top-line expansion, AAOI presents a compelling narrative with its remarkable 82.8% year-over-year revenue growth. This indicates strong market demand for its products, even if it has yet to translate into profitability. The impressive growth trajectory suggests significant potential for future scaling and market share gains, which could appeal to those with a higher risk tolerance looking for high-growth opportunities. However, the negative net margin and free cash flow yield suggest higher operational risks associated with its current growth phase.

When considering AAOI vs VECO fundamentals and valuation, value investors might find VECO more appealing. Despite a high P/E of 155.27x, it is consistently profitable, unlike AAOI, which currently trades with a negative P/E of -261.13x due to losses. VECO’s P/B ratio of 4.06x is also significantly lower than AAOI’s 10.23x, implying a more reasonable valuation relative to its book assets. Furthermore, VECO’s Discounted Cash Flow (DCF) model indicates a less severe overvaluation compared to AAOI, suggesting a potentially better entry point for value-conscious investors.

Neither AAOI nor VECO are suitable for income-focused investors, as both stocks currently have a 0% dividend yield. Therefore, if your primary investment goal is to generate regular income through dividends, you should look elsewhere. Ultimately, the decision on should I buy AAOI or VECO stock in 2026 depends heavily on your individual risk tolerance and investment objectives, particularly whether you prioritize aggressive growth potential despite current unprofitability or a more stable, albeit slower-growing, profitable enterprise. This is not investment advice.
