Why SMR stock is down today

NuScale Power stock fell 11.75% to $9.01 in intraday trading after UBS downgraded the stock to Sell from Neutral and cut its price target to $6. The downgrade cited concerns over NuScale’s long construction timeline, lack of firm customer commitments, and an estimated $700 million in cumulative cash burn through 2028. The stock opened at $9.81, down 3.9% from the prior close, and continued to decline throughout the session.

What Happened

UBS downgraded NuScale Power to Sell, lowering its price target to $6. The firm highlighted the company’s extended build timeline and financial challenges as key risks. These concerns were echoed in multiple reports and headlines over the past 36 hours, which cited the downgrade as the primary reason for the stock’s sharp decline. NuScale’s shares had previously gained 10.2% over the last eight sessions, rising from $9.28 to $10.23. However, the recent downgrade triggered a rapid reversal in sentiment. The stock reached a session high of $9.90 before falling to a low of $9.00.

Retail traders on social media platforms noted the downgrade as a catalyst, with some calling the stock oversold. Recent insider transactions also reflect a lack of confidence, with the CFO and a director selling shares totaling $836,000 over the past 90 days.

What The Data Shows

The stock traded 31.9 million shares, matching its 3-month average volume. NuScale remains unprofitable with an EPS of -1.54 for the trailing twelve months and revenue down 81% year-to-date. The stock has printed 21 fresh 52-week lows on September 11, 2026, while hitting only one 52-week high. Its market cap is $4.4 billion, and it carries a beta of 2.31, indicating high volatility.

What To Watch

Investors should monitor the company’s progress on securing firm customer commitments and its cash burn rate. No earnings date is provided, but coverage breadth and analyst ratings will remain key indicators for near-term direction.
