A maker of wireless infrastructure, SBA Communications owns and leases tens of thousands of cell towers across the Americas and Africa, renting antenna space on them to carriers like T-Mobile, AT&T, and Verizon. Founded in 1989 by Steven Bernstein as a consulting firm, it began as "Steven Bernstein and Associates"—the source of the SBA name—and launched with credit card cash advances from a basement office before pivoting to owning towers in 1997. Its customers often share the same tower, co-locating equipment to serve more people without building new ones.
Select a row to see that insider’s individual transactions. † Sum of the holdings confirmed in the 12 months before this insider's last filing. A Form 4 reports a holding per line — held directly, or through a named trust, partnership or foundation, and in each share class separately — never a person’s total. Lines not restated in that time are left out and shown apart: an active filer restates what they still hold, so a line they did not restate is more often an entity since renamed, whose shares a successor line reports too. An amber marker means some were left out.
