Assessment
Our Rating
A journalistic assessment by our editorial team at the time of the deep dive — it rates the company, not the entry point. Not investment advice and not a solicitation to buy or sell.
The business works in principle, but one material question is open. As long as it stays open, our findings do not carry a quality verdict.
Why this colour
Yellow because a material operating question is open — not because the balance sheet is shaky. The substance is there: $46,294,870 of equity against $17,408,885 of liabilities, debt fixed at 4.192 percent until 2036, interest covered 3.5 times, and a profit in every one of the last seven years. What is open is whether the company can close the cost squeeze: in the first quarter of 2026 the stores' cost of operations grew 10.0 percent, nearly seven times as fast as the 1.5 percent revenue increase, net operating income fell 3.9 percent and FFO fell 12.6 percent — which left the unchanged dividend consuming 96 percent of cash flow and the cash balance shrinking for the first time in years. Add an idle growth engine (no acquisitions in 2025, one single third-party management client since 2019) and the roughly 8.8 percent of dilution approved in June 2026. On the stock itself: about fourteen times FFO is no bargain for a portfolio that is not growing, and the price sits below what the company charged for new shares in 2021 — but that remains a price argument and does not set the light. The decision is yours.
What the thesis turns on
Assessment: Opportunities & Risks
Global Self Storage runs its 13 storage properties about as well as anyone in the sector: 93.1 percent occupancy and a record average tenant stay of roughly 3.6 years as of March 31, 2026, on top of a lean balance sheet with debt fixed at 4.192 percent until 2036. The price of that quiet sits in the quarterly report: cash flow (FFO) fell 12.6 percent to $852,563, the dividend paid cost $820,470 — 96 percent — the cash balance dropped by $48,180, nothing was bought in 2025, and in June 2026 stockholders released one million new shares for compensation, lifting potential dilution to roughly 8.8 percent by the company's own calculation. Buying here means buying a very quiet business and a payout with four percent of room. Not investment advice.
Operating quality
The twelve same-store properties were 93.1 percent occupied as of March 31, 2026 (92.1 percent in the prior-year quarter) and the average tenant duration of stay reached a record of roughly 3.6 years. In its May 8, 2026 earnings release the company calls this the highest occupancy and occupancy growth in the sector — under month-to-month leases that make every rate increase effective immediately.
Balance sheet and financing
As of March 31, 2026, total assets of $63,703,755 carried only $17,408,885 of liabilities, with equity of $46,294,870. The main loan, originally $20 million, is fixed at 4.192 percent until July 1, 2036, 2025 operating income covered interest expense 3.5 times over, and the $15 million credit facility was undrawn as of December 31, 2025.
Dividend coverage
In the first quarter of 2026 the $820,470 of dividends paid consumed roughly 96 percent of the $852,563 of FFO (prior-year quarter: 84 percent). After maintenance capital spending and amortization the cash balance fell by $48,180, having risen $59,997 a year earlier. The 2025 annual report itself calls capital resources derived from retained cash flow "negligible."
Cost trend
In the first quarter of 2026 same-store revenue rose 1.5 percent to $3,155,135 while the stores' cost of operations climbed 10.0 percent to $1,330,343. Net operating income fell 3.9 percent to $1,824,792 and operating income dropped 21.0 percent to $571,776. Property tax reassessments are hard to pass on under month-to-month leases — the annual report states expressly that tax increases generally are not passed through to tenants.
Growth and capital deployment
No store was acquired in 2025 even though roughly $24.5 million of capital resources stands ready (March 31, 2026), including an undrawn $15 million credit facility and a $15 million share offering program that went unused in 2025. The third-party management platform has had exactly one client since its first contract on October 23, 2019; management fees and other income came to $18,619 in the first quarter of 2026.
Dilution and entanglement
Stockholders approved one million new shares for the pay plan on June 16, 2026 (S-8 registration June 29, 2026); potential dilution rises from 3.34 to roughly 8.8 percent per the proxy statement, and 1,298,704 shares were voted against. At the same time, $3,152,802 of 2025 personnel costs — 24.8 percent of revenue — flowed through Midas Management Corporation, a subsidiary of Winmill & Co. Incorporated, whose voting stock is held by the Winmill Family Trust.
Worth Noting
Global Self Storage reached the research list through our in-house Reddit hype scanner (Reddit mentions, as of July 30, 2026). The live cross-check the same day showed that SELF appears in none of our scanner result lists — those lists are recalculated daily, so the finding holds for that date.
The market value of roughly $58.1 million (data as of July 30, 2026) was checked against the filings: 11,421,732 shares outstanding (quarterly report cover page, May 7, 2026) times the $5.10 closing price of December 31, 2025 (from the proxy statement) equals $58.25 million — a 0.2 percent deviation. All valuation multiples rest on that basis; the analysis is evergreen and daily prices are not a reason to buy.
Not to be confused: Global Self Storage was a closed-end investment fund until January 2016; the names Bull & Bear Global Income Fund, Global Income Fund and Self Storage Group belong to the prehistory of the same entity. The Form 25 filed with the SEC in 2008 relates solely to that old fund structure: on March 27, 2008 the then Global Income Fund, Inc. gave notice of the voluntary withdrawal of its shares from listing on the American Stock Exchange, while remaining registered as an investment company. It has nothing to do with today's listing — the stock has been listed on Nasdaq since January 19, 2016.

What Do These Terms Mean?
- EPS (Earnings Per Share):
- Quarterly profit divided by the total share count — how much of the profit works out to a single share.
- YoY (Year over Year):
- Change versus the same quarter a year ago — this is how you compare without seasonal distortion (e.g. the holiday shopping season).
- Sales:
- All revenue for the quarter, before any costs are deducted — the top line of the income statement.
- Net Margin:
- What percentage of sales is left over as profit in the end. Negative means the company is posting a loss.
- OCF (Operating Cash Flow):
- The cash that actually flows into the till from the core business during the quarter — harder to dress up than book profit.
- FCF (Free Cash Flow):
- Operating cash flow minus capital expenditures — the money that's genuinely free to use, say for paying down debt, buybacks, or dividends.

Valuation
What is priced in?
Instead of guessing what the stock is worth, we turn the question around: what free cash flow growth has to happen for today’s market value to add up? The assumptions behind it can be moved.
Today’s market value implies roughly 3.4% growth in free cash flow per year over ten years (assumptions: discount rate 10.0%, terminal growth 2.5%).
| Free cash flow (last twelve months) | $4.0M |
|---|---|
| Market cap | $59.0M |
| Free cash flow in year ten | $5.7M |
| Terminal value as a share of market value | 50.5% |
For comparison: over the past five years free cash flow grew by 18.2% per year.
It shows which assumption is built into today’s price, not whether that assumption will hold. Every assumption can be changed with the sliders; the figures move with them.
A simplified model calculation — not a forecast and not a recommendation.
