5 Mid-Cap AI Infrastructure Stocks to Buy With Deep Discounted Value

The AI infrastructure sector is experiencing significant momentum, driven by easing recession fears, anticipated Fed rate cuts, and substantial capital expenditure increases, notably a 46% year-over-year rise to $325 billion in 2025 from four 'Magnificent 7' companies. This bullish environment positions select mid-cap AI infrastructure stocks, including UiPath, Five9, C3.ai, Qualys, and Fastly, as attractive long-term investments due to their recent outperformance against the S&P 500 and perceived discounted valuations with potential for future large-cap status.

Analysis

The AI infrastructure sector is being propelled by a favorable macroeconomic outlook, including anticipated Fed rate cuts and diminishing recession fears, alongside a significant acceleration in capital allocation. Specifically, four 'Magnificent 7' companies are projected to increase capital expenditures by 46% year-over-year to $325 billion in 2025, signaling a robust demand environment for AI-related services and hardware. This backdrop highlights an opportunity in select mid-cap stocks—UiPath (PATH), Five9 (FIVN), C3.ai (AI), Qualys (QLYS), and Fastly (FSLY)—which have all outperformed the S&P 500 in the last three months and carry strong buy or buy ratings from Zacks. These companies exhibit varied financial profiles: PATH, FIVN, and QLYS are profitable and trade at P/E ratios (23.9X, 10.1X, and 8.8X, respectively) below their industry averages, suggesting relative value. In contrast, C3.ai and Fastly are not yet profitable but demonstrate strong growth potential, with C3.ai expecting 20.1% revenue growth and Fastly anticipating 25% earnings growth for 2025. Reinforcing this positive outlook, all five firms have seen upward revisions to their consensus earnings estimates within the last 60 days, with C3.ai's estimate improving by a notable 19.6%.

Key Decisions for Investors

• Investors should consider initiating or adding to positions in mid-cap AI infrastructure providers to gain exposure to the sector's significant capital expenditure cycle, which is projected to reach $325 billion in 2025.
• For a value-oriented approach, focus on the profitable names like Five9 (FIVN) and Qualys (QLYS), which trade at significant P/E discounts to their industry peers, but note the modest 0.7% earnings growth forecast for QLYS.
• For those with higher risk tolerance, the unprofitable but high-growth C3.ai (AI) and Fastly (FSLY) may offer greater upside, contingent on their ability to convert strong revenue growth and positive earnings estimate revisions into future profitability.
• Monitor enterprise AI adoption rates and execution on forward-looking growth targets, as these will be critical catalysts for realizing the long-term potential of these mid-cap names to transition into large-cap stocks.
