    Sector wide rally puts fresh attention on SBA Communications

    SBA Communications (SBAC) jumped 8.1% in a broad rally across cell tower operators, drawing fresh attention to a stock that some investors currently view as trading below estimated fair value.

    The move came without company specific headlines. As a result, the spotlight has shifted to fundamentals such as tower leasing capacity, refinancing plans through 2027, and international expansion, as investors reassess what they are paying for SBAC today.

    Recent trading paints a mixed picture for SBA Communications. The share price has climbed 11.9% over the past month and 6.3% across 90 days, yet the year-to-date share price return is down 3.4% and the 5-year total shareholder return has declined 41.8%. This points to improving short-term momentum alongside a weaker long-term record.

    Compare SBA Communications with a hand picked group of tower and infrastructure peers using the 55 AI infrastructure stocks as you reassess whether the sector rally could be overreacting or still underpricing growth.

    SBA Communications just popped on sector enthusiasm, not fresh news. Does that 8.1% jump better reflect the tower portfolio and cash flows, or has sentiment simply swung from too cold to too warm?

    Most Popular Narrative: 18% Undervalued

    SBA Communications last closed at $185.92, while the most followed narrative anchors fair value at $226.40. This frames the recent 8.1% jump as a move inside what some see as a wider valuation gap rather than the end of it.

    Recycling capital from divested subscale portfolios into an investment grade balance sheet, share repurchases of roughly US$0.5b at prices management views as accretive, and a larger unsecured debt platform with a US$2.5b revolver positions SBA Communications to convert future lease up and international growth into higher FFO and AFFO per share after the 2026 and 2027 refinancing period.

    See why 11 investors see SBA Communications as 18% undervalued.

    Result: Fair Value of $226.40 (UNDERVALUED)

    Still, the thesis around SBA Communications can be upset if carrier consolidation drives higher churn or if refinancing lifts interest costs beyond what cash flow can comfortably absorb.
