A self-storage real estate company, renting out thousands of units where people and businesses keep everything from furniture to inventory. Founder Kenneth Woolley was inspired while studying at Stanford, building his first facility in Billings, Montana under the name "Secure-it Mini Storage" before the brand grew into Extra Space Storage. Today it's the largest U.S. self-storage operator, managing stores for other owners and even reinsuring tenants' goods against loss.

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.
Net open-market activity over the last 5 years: -151.7K shares. Grants, option exercises and tax withholding are excluded — they are compensation mechanics, not decisions to buy or sell.
