BigBear.ai Stock Down 37% This Year Despite 36% Upside Target

What happened

BigBear.ai, an AI software company serving defense and government clients, has fallen 37% in 2026 but trades at a median 12-month price target of $5, suggesting potential 36% upside. The turnaround is being driven by its December 2025 acquisition of Ask Sage for $250 million（約400億円）, which contributed to Q1 revenue of $34.4 million（約55億円） (down just 1% year-over-year) and a gross margin jump of almost 13 percentage points to 34%.

Why it matters

BigBear.ai's 2025 performance was weak—revenue fell 19% to $127.7 million（約200億円） and margins contracted sharply—making the company highly dependent on government contract timing and funding. The Ask Sage acquisition, which brought higher-margin generative AI products, appears to be restoring growth; the company has guided for full-year revenue of $135 million（約220億円） to $165 million（約260億円） (midpoint implying 17% growth), and recorded new contract wins of almost $75 million（約120億円） in Q1. However, analysts project slower mid-single-digit growth in 2027, and the stock's 12× sales valuation is significantly above the Nasdaq Composite's 5.4×, raising questions about whether the company can justify its premium.

What to watch

BigBear.ai's ability to sustain momentum beyond the inorganic boost from Ask Sage will be critical; the company's turnaround appears heavily dependent on the acquisition's contribution, and slower projected growth in 2027 may continue to pressure the stock despite the price target upside.
