Better Artificial Intelligence Stock: BigBear.ai vs. UiPath

BigBear.ai and UiPath represent two distinct plays on enterprise AI: BigBear.ai sells edge-deployed AI modules and has leaned on acquisitions (Pangiam for $70M, pending Ask Sage for ~$250M) and a new CEO to drive growth, but its core business has stalled—revenue barely rose from $146M in 2021 to $158M in 2024, management now guides 2025 revenue down 11–21% to $125–$140M, gross margin has slipped to 22.8%, and it remains unprofitable; the market values BigBear.ai at an enterprise value of $3.1B (~19x next-year sales). By contrast, UiPath, the RPA market leader, still shows healthy organic growth (revenue from $608M in FY2021 to $1.4B in FY2025, guidance for ~11–12% revenue growth in FY2026), an 85% adjusted gross margin, recent GAAP profitability, and analyst expectations for continued revenue and EPS expansion—its EV is ~$8.4B (about 5x next-year sales). Given UiPath’s stronger margins, profitability, scale in a rapidly expanding RPA market, and much lower revenue multiple, the article concludes UiPath is the superior investment today.

Analysis

BigBear.ai has underperformed its early promises with core revenue rising only from $146 million in 2021 to $158 million in 2024, and management guiding 2025 revenue down 11%–21% to $125–$140 million; the company has leaned on acquisitions (Pangiam for $70 million and a pending ~ $250 million Ask Sage deal expected to close by end-2025/early-2026) and a new CEO, yet backlog fell from $385 million to $376 million and gross margin compressed 240 basis points to 22.8% in the first nine months of 2025, leaving it unprofitable and dependent on successful integration of deals that currently support a 2026 analysts’ rebound to $164 million but a 2027 dip to $162 million. UiPath remains the RPA market leader with revenue rising from $608 million in FY2021 to $1.4 billion in FY2025 (24% CAGR) and guidance for ~11%–12% revenue growth to nearly $1.6 billion in FY2026; adjusted gross margin held at 85% in the first nine months of fiscal 2026, the company returned to GAAP profitability, and analysts project FY2027 revenue and adjusted EPS growth of ~9% and 13% respectively, supported by a Grand View Research estimate of a 43.9% CAGR for the RPA market from 2025–2030. Valuation and risk profile favor UiPath: BigBear.ai’s enterprise value of $3.1 billion implies ~19x next-year sales versus UiPath’s $8.4 billion EV at ~5x next-year sales, making UiPath the more compelling risk-adjusted buy given scale, margins, and profitability, while BigBear.ai’s outlook is weighed down by government contract consolidation, acquisition execution risk, and weak organic growth; investors should still monitor UiPath’s revenue deceleration trends, competitive pressure from generative AI, and management stability as downside catalysts.
