# Public Storage: Business Model & Revenue Engine

## Direct Answer

Public Storage reports revenue across 2 business segments in its fiscal 2025 Form 10-K. Self Storage Operations is the largest, with $4.5 billion of revenue (93% of the total), followed by Ancillary Operations at $335 million (7%).

## How Does Public Storage Make Money?

Self Storage Operations supplies 93% of revenue, so Public Storage's results move mostly with that one business; the others matter more for diversification than for the headline number. Between fiscal 2024 and 2025, Ancillary Operations grew fastest (+11.7%) and Self Storage Operations slowest (+2.1%), so the revenue mix tilts toward Ancillary Operations while that gap lasts.

| Segment | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Self Storage Operations | $4.5 billion | $4.4 billion | 93.1% | 2.1% |
| Ancillary Operations | $335 million | $300 million | 6.9% | 11.7% |

## What Does Public Storage Sell?

Public Storage also breaks revenue down by product and service line, which shows what customers pay for rather than how management organizes the business.

| Product or service | FY2025 revenue | FY2024 revenue | Share of revenue | Change |
| --- | --- | --- | --- | --- |
| Self Storage Operations | $4.5 billion | $4.4 billion | 93.1% | 2.1% |
| Ancillary Operations | $335 million | $300 million | 6.9% | 11.7% |

## What the Segment Figures Do Not Show

The rows above add up to 100% of Public Storage's reported revenue for fiscal 2025; the difference is intersegment eliminations, corporate revenue or items the company reports outside its segments. Segment definitions are management's choice and change when a company reorganizes, in which case it restates prior years in the next filing, so a multi-year comparison should use the figures from a single filing. Revenue shows where sales come from, not where profit or cash is earned: a small segment can carry most of the margin.

## Where These Numbers Come From

Every figure on this page is a value Public Storage reported in the segment note and revenue disclosures of its Form 10-K filed February 12, 2026 (accession 0001628280-26-007696), read from the SEC's Financial Statement Data Sets. The prior-year column is the comparative figure from that same filing, so it reflects any restatement for a change in segments. Category names are the company's own XBRL labels, lightly reformatted for reading.

Rows that only total other rows (for example a "Products" line beside the individual products) are left out so nothing is counted twice. This page is educational and describes reported history for fiscal 2025; it is not a forecast or a recommendation.
