Why X-Energy Stock Collapsed 19.2% This Week

X-Energy (XEN) dropped 19.2% this week after the nuclear startup disclosed a two-year delay to its first Amazon project, now expected online in 2027, and absorbed a Jefferies downgrade slashing the price target from $30 to $22.

The company's Xe-100 reactor design still lacks Nuclear Regulatory Commission approval, leaving X-Energy without a path to near-term revenue generation. Despite the absence of an established commercial operation, the stock carries a $7.5 billion market capitalization following the week's selloff.

Jefferies cited the extended construction timeline and regulatory uncertainty as key drivers of the downgrade. The Amazon project, announced as a flagship deployment for X-Energy's small modular reactor technology, was originally slated for a mid-decade launch. The 2027 revision marks a significant setback for a company trading on future growth expectations rather than current cash flow.

The stock now trades well below the Jefferies $22 target following the week's decline, reflecting investor concern that revenue generation remains years away while the valuation implies imminent commercialization.
