Strong Institutional Support Growing
Major institutional investors have been increasing BigBear.ai positions throughout 2025. Goldman Sachs boosted its stake by 569% during the first quarter, now holding 2.34 million shares worth approximately $6.69 million.
Jump Financial established a new $37.4 million position in the second quarter. Geode Capital Management increased holdings by 125.2%, while Vanguard Group raised its stake by 9.2%.
Despite growing institutional interest, overall institutional ownership remains at just 7.55% of outstanding shares. This leaves substantial room for additional institutional buying if the company continues executing its growth strategy.
Recent earnings showed mixed results with the company reporting a $0.06 per share loss, beating analyst estimates by $0.01. However, revenue declined 18.3% year-over-year to $32.47 million, falling short of the $41.18 million consensus estimate.
HC Wainwright analysts recently lowered their price target from $9 to $8 while maintaining a buy rating. The consensus analyst rating stands at “moderate buy” with an average price target of $6.
BigBear.ai stock has traded between $1.36 and $10.36 over the past 12 months, with current prices near the middle of this range as investors evaluate the company’s airport technology expansion potential.
