Why SoundHound AI Stock Plummeted 46% in the First Half of 2025 but Has Been Bouncing Back

SoundHound AI (SOUN) shares declined 45.9% in the first half of 2025, driven by factors including a reaction to strong prior gains, increased competition from DeepSeek, disappointing CES expo outcomes, and notably, Nvidia's divestment of its stake in the company. Despite this pullback, SOUN saw a significant rebound in May after reporting Q1 results with sales up 151% year-over-year to $29.1 million, exceeding market targets. The company projects full-year sales between $157 million and $177 million, indicating continued strong growth, and has experienced further gains in July, highlighting its growth-dependent valuation.

Analysis

SoundHound AI (SOUN) experienced significant share price volatility in 2025, marked by a 45.9% decline in the first half of the year, starkly underperforming the S&P 500's 5.5% gain. This pullback was driven by several negative catalysts, most notably the disclosure in February that key strategic investor Nvidia had divested its entire stake, removing a significant source of market confidence. Additional pressures included increased competition from rivals like DeepSeek and a lack of impactful announcements at the CES expo. Despite these headwinds, the company demonstrated strong operational momentum in its first-quarter results, reporting a 151% year-over-year revenue increase to $29.1 million, which surpassed market expectations and spurred a stock rebound in May. Looking forward, the company's guidance for full-year revenue between $157 million and $177 million implies an acceleration in annual growth to approximately 97% at the midpoint. This aggressive growth trajectory supports its premium valuation of roughly 29 times forward sales, but also underscores the stock's high dependency on flawless execution and its vulnerability to any potential shortfalls in meeting these ambitious targets.

Key Decisions for Investors

• Investors should closely monitor the company's ability to meet its aggressive revenue guidance of $157-$177 million, as the stock's high valuation at 29 times forward sales leaves little room for execution error.
• Given Nvidia's divestment signals a potential loss of a key strategic partner, traders should watch for new institutional filings or partnership announcements that could either validate or further question the company's long-term competitive position.
• For investors with a high risk tolerance, the 45.9% price correction in the first half of 2025 may present a speculative entry point based on strong revenue acceleration, but a cautious approach is warranted due to competitive pressures and the recent exit of a major backer.
