Let’s take a look at these stocks in detail.

SoundHound Q1 Beat Fails to Impress Investors

SoundHound reported Q1 revenue of $44.2 million, up 52% year over year and ahead of Wall Street estimates. The company also posted a loss of $0.06 per share, better than the expected loss of $0.10. However, management expects losses to improve gradually over the coming quarters.

Despite the strong headline numbers, SOUN stock has moved lower since earnings as investors focused more on concerns around profit margins, valuation, and the pace toward profitability. The company also reaffirmed its 2026 revenue guidance of $225 million to $260 million, pointing to expected growth of roughly 33% to 54%, but the lack of an upward revision disappointed the market.

SOUN still trades at a premium valuation, with a trailing price-to-sales ratio of 18.94 compared to the sector average of 3.86. This high valuation reflects strong investor expectations for future growth, but it also leaves little room for mistakes. At the same time, SOUN stock had already surged sharply over the past year, pushing market expectations even higher. Because of that, solid quarterly results alone were not enough to impress investors, who are now looking for faster revenue growth and a clearer path toward long-term profitability.

BigBear.ai Struggles with Slower Growth Momentum

In comparison, BBAI reported Q1 revenue of $34.4 million, slightly ahead of analysts’ expectations of $33.6 million. However, revenue was mostly flat compared to $34.8 million in the same quarter last year. The bigger disappointment came from earnings, as the company reported a loss of $0.12 per share, worse than analysts’ expectations for a loss of $0.08 per share, raising concerns among investors.

The company said growth from its newer generative AI products was partly offset by weaker demand from older Army-related programs. The company is still struggling to generate consistent profits, margins remain weak, and its reliance on government contracts can lead to uneven revenue due to changing federal budget cycles.

In terms of valuation, BBAI looks somewhat cheaper, with a price-to-sales ratio of 14.04. However, that lower valuation also reflects the company’s slower growth and ongoing financial pressures. In addition, its heavy dependence on government contracts can make revenue growth less predictable from quarter to quarter.

Conclusion

SoundHound is still in expansion mode and has not become profitable yet. The company continues to spend heavily on technology, products, and customer growth. Analysts currently have a Strong Buy rating on SOUN stock, with an average price target of $13.30, implying potential upside of 58%.

Meanwhile, BBAI also continues to face profitability challenges, and its dependence on government contracts can lead to uneven revenue tied to federal budget cycles. Compared to SOUN, analysts have a Moderate Buy rating on BBAI, with an average price target of $5.33, implying a lower upside potential of about 27%.
