AOSL vs LAES: key metrics side by side

Full side-by-side comparison of AOSL and LAES across valuation, profitability, growth and analyst sentiment. Data updated 2026-05-12.

AOSL vs LAES valuation comparison

When considering the AOSL vs LAES valuation, both companies present interesting, albeit challenging, profiles given their current unprofitability. Alpha and Omega Semiconductor Limited (AOSL) trades at a Price-to-Earnings (P/E) ratio of -10.86x, while SEALSQ Corp (LAES) is at -12.08x. While both are negative, reflecting ongoing losses, the numerically larger negative P/E for LAES could suggest a market paying more for its negative earnings, or simply reflect its early growth stage. However, a closer look at the Price-to-Book (P/B) ratio reveals LAES as potentially cheaper relative to its assets, standing at 0.9x compared to AOSL’s 1.44x. This suggests investors are valuing LAES at a discount to its book value, whereas AOSL is trading above its book value.

Further complicating the AOSL vs LAES valuation picture are their Discounted Cash Flow (DCF) analyses. AOSL has a DCF of $6.91, indicating a significant -82.1% downside from its current price, suggesting it is substantially overvalued by this metric. LAES, on the other hand, shows an even more concerning DCF of $-0.68, translating to a -122.2% downside, indicating a deeply negative intrinsic value. This implies that neither company is considered undervalued based on their future cash flow potential in these models, with LAES’s situation being more severe. Therefore, while LAES appears cheaper on a P/B basis, the DCF models suggest substantial overvaluation for both, with LAES having a more pronounced negative intrinsic value.

AOSL vs LAES growth comparison

In the AOSL vs LAES growth comparison, SEALSQ Corp (LAES) clearly demonstrates stronger momentum. LAES has posted an impressive year-over-year revenue growth of +46.4%, significantly outperforming Alpha and Omega Semiconductor Limited (AOSL), which reported a more modest revenue growth of +5.9%. This substantial difference highlights LAES’s position as a high-growth company, likely expanding its market share or introducing new products at a faster pace than its counterpart. While AOSL maintains a much larger revenue base at $696,162,000 compared to LAES’s $18,252,000, LAES’s percentage growth rate suggests it is scaling rapidly from a smaller base.

However, it is crucial to consider that LAES’s aggressive growth comes at a significant cost, as evidenced by its deeply negative margins discussed in the profitability section. While LAES is experiencing rapid top-line expansion, this growth is currently not translating into positive earnings or cash flow. For investors prioritizing high-speed expansion and future potential over immediate profitability, LAES’s growth trajectory is more compelling. On the other hand, AOSL’s more conservative growth, coupled with its significantly better (though still negative) profitability, might appeal to those seeking a more established business with a clearer path to sustainable operations, even if its growth pace is slower in the current market.

AOSL vs LAES profitability

When examining AOSL vs LAES profitability, Alpha and Omega Semiconductor Limited (AOSL) stands out as the significantly stronger performer, despite both companies currently operating at a loss. AOSL reported a net margin of -15.51%, which, while negative, is far superior to LAES’s alarming net margin of -187.34%. This indicates that LAES is incurring losses almost twice the size of its revenue, highlighting severe operational inefficiencies or significant investment phases. Furthermore, AOSL boasts a positive EBITDA margin of 2.81%, demonstrating its ability to generate operating profit before non-cash expenses, interest, and taxes. In stark contrast, LAES recorded a deeply negative EBITDA margin of -185.15%, underscoring its profound challenges in covering operational costs.

Both companies have a Return on Equity (ROE) listed as N/A%, which typically occurs when a company has negative equity or the metric is not calculable under current financial conditions. However, the Free Cash Flow (FCF) yield further emphasizes AOSL’s relative financial health. AOSL’s FCF yield is -5.25%, meaning it is burning cash relative to its market capitalization, but at a much lower rate than LAES, which has an FCF yield of -9.17%. In this profitability comparison, AOSL clearly generates more cash relative to its market cap and manages its expenses far more effectively than LAES, making it the more financially robust option, despite its own current unprofitability.

Analyst ratings: AOSL vs LAES

In terms of analyst ratings, there’s a notable difference in both coverage and sentiment for AOSL vs LAES. Alpha and Omega Semiconductor Limited (AOSL) is covered by 11 analysts, with 45.5% issuing a “Buy” recommendation. The consensus for AOSL is a “Buy” rating, with an average target price of $43, representing a potential upside of +11.3% from its current price. This suggests a moderately positive outlook from a relatively diverse group of financial professionals, indicating some confidence in the company’s future performance, though not a unanimous endorsement.

On the other hand, SEALSQ Corp (LAES) receives unanimous support from the analysts covering it. While only 2 analysts currently provide ratings for LAES, both have issued “Buy” recommendations, leading to a 100.0% Buy rating and a strong “Buy” consensus. More strikingly, the average target price for LAES is $7.5, which implies a substantial potential upside of +145.1% from its current trading price. Despite the limited analyst coverage, this high conviction and significant upside potential make LAES appear to be the preferred choice among the analysts who currently follow the stock, suggesting a belief in its higher growth trajectory and significant undervalued potential.

Should I buy AOSL or LAES stock in 2026?

When considering should I buy AOSL or LAES stock in 2026, the answer largely depends on your investment philosophy and risk tolerance. For growth investors seeking high revenue expansion, LAES stands out with its impressive +46.4% year-over-year revenue growth, significantly outpacing AOSL’s +5.9%. LAES offers a much higher potential upside according to analyst targets (+145.1%), compared to AOSL’s +11.3%. However, this comes with considerably higher risk, as LAES exhibits deeply negative profitability metrics, including a -187.34% net margin and -185.15% EBITDA margin, indicating significant cash burn to fuel its expansion.

For value investors, the AOSL vs LAES fundamentals and valuation present a complex picture. LAES appears cheaper on a Price-to-Book ratio of 0.9x versus AOSL’s 1.44x. While both have negative P/E ratios, LAES’s is numerically lower at -12.08x compared to AOSL’s -10.86x, which in the context of losses, could be interpreted in different ways depending on future prospects. However, AOSL’s profitability is markedly superior with a positive EBITDA margin of 2.81% and a less severe negative net margin of -15.51%, alongside a less negative FCF yield. Furthermore, AOSL’s DCF upside, while still deeply negative at -82.1%, is less dire than LAES’s -122.2%, suggesting a potentially less overvalued position on an absolute intrinsic value basis.

For income-focused investors, neither AOSL nor LAES is suitable, as both currently have a 0% dividend yield. Ultimately, if you prioritize aggressive growth and are willing to stomach significant losses and high risk for potentially massive returns, LAES might be more appealing, especially given the strong analyst conviction and upside. If you prefer a company with a larger revenue base, slower but more stable growth, and significantly better (though still negative) profitability, AOSL could be the less speculative choice. This is not investment advice, and you should always conduct thorough personal research.
