Most Popular Narrative: 13% Undervalued

The most followed narrative for Anterix pegs fair value at $86.00, which sits above the latest $74.90 close. This frames the recent pullback as a potential valuation gap rather than a completed story.

Although utilities are showing interest in private broadband networks as they modernize grids, Anterix still has roughly 85% of its spectrum yet to be monetized. Any delay in converting that interest into contracts could slow the realization of expected spectrum value and defer cash inflows and earnings.

Result: Fair Value of $86.00 (UNDERVALUED)

Still, Anterix faces real tripwires if utilities slow 900 MHz contract signings, or if spectrum clearing and FCC licensing progress more slowly than investors expect.
