Due Diligence Capital Notes

The company formerly known as MicroStrategy — a mid-tier enterprise analytics software firm operating out of Tysons Corner, Virginia — renamed itself "Strategy Inc." on August 11, 2025. Not a rebrand. A rename. The old name still worked perfectly well. The new one is a declaration: this company is no longer primarily a software business; it is a bitcoin treasury machine that happens to still sell software on the side.

What makes that declaration remarkable is the context in which it was made. When Strategy filed its fiscal year 2025 10-K annual report with the SEC on February 19, 2026, the company disclosed that it held 717,131 BTC acquired at a total cost of $54.5 billion — an average purchase price of roughly $76,027 per bitcoin, inclusive of fees and expenses. On the filing date itself, bitcoin was trading at $68,734 on Coinbase. That means the aggregate position was sitting at an unrealized loss north of $5 billion. And the company's response to that situation? Keep buying. No hedges. No apologies. No pivot.

That posture either strikes you as visionary or reckless depending on your priors. Understanding why it isn't obviously insane requires a close look at the financial architecture Strategy has built to support it.

From Software Company to Bitcoin Treasury Engine

Strategy describes itself, without irony or qualification, as "the world's first and largest Bitcoin Treasury Company." The 10-K states plainly: "We pursue financial innovation strategies designed to generate value from our bitcoin holdings, including by developing and issuing novel fixed-income instruments that provide investors varying degrees of economic exposure to bitcoin."

The software segment — AI-powered enterprise analytics tools — still exists. It still generates revenue. But it is no longer the point. The point is the 717,131 BTC, which as of February 13, 2026, represents more than 3.5% of the approximately 20.0 million bitcoin that had ever been mined against the hard cap of 21 million coins. No other publicly traded corporation comes close.

How did the company accumulate a position that large? Not through operating cash flows — the software business alone could never generate $54.5 billion in capital. The answer is a capital markets engine that most retail investors have never seen assembled quite this way.

The Capital Stack: How Strategy Funds the Accumulation

The machinery behind Strategy's bitcoin accumulation rests on three interlocking components. Each one taps a different corner of the capital markets, and together they allow the company to keep buying bitcoin without depending on any single source of funding.

ATM (At-The-Market) equity offerings — an ATM is a mechanism that lets a company sell new shares gradually into the open market at prevailing prices, rather than all at once in a traditional underwritten offering. Because Strategy's stock typically trades at a significant premium to the underlying value of its bitcoin (the NAV, or Net Asset Value — the market price of the bitcoin held, minus all debt, divided by shares outstanding), issuing new shares and using the proceeds to buy bitcoin can actually increase the value of each existing share. If you're selling a dollar's worth of stock at two dollars and deploying the proceeds into an asset worth a dollar, the math works in existing shareholders' favor. This is what the company calls accretive dilution — more shares outstanding, but more bitcoin per share.
Convertible notes — a convertible note is a corporate bond that pays interest but also carries the right for the bondholder to convert the principal into stock at a predetermined price. Strategy has issued convertible notes at very low interest rates — sometimes near zero — because the embedded conversion option is valuable to buyers. Fixed-income investors are essentially sacrificing yield today in exchange for the right to participate in bitcoin's upside through the stock. For Strategy, this means raising large sums of capital at minimal interest expense. The $2.25 billion USD Reserve established in December 2025 exists specifically to backstop near-term dividend and interest obligations across the full capital structure, ensuring the company can meet its fixed obligations even if bitcoin prices fall sharply.
Perpetual preferred stock series — in 2025, Strategy launched five distinct series of perpetual preferred stock: STRF (10% dividend rate), STRC (variable rate), STRE (10%, Euro-denominated), STRK (8%, convertible into common stock at a high strike price), and STRD (10%). A perpetual preferred stock is a hybrid instrument — it pays a fixed dividend like a bond, but it has no maturity date and sits below debt but above common equity in the capital structure. These are what Strategy calls "digital credit" instruments, offering investors indirect exposure to bitcoin's economics without requiring them to hold bitcoin directly. For the common shareholder, preferred stock is attractive because it raises capital with no immediate dilution to the common equity. The dividend obligation is real, but the $2.25 billion reserve cushions it.

The 10-K summarizes the strategic logic this way: "We believe our combination of active bitcoin-focused capital management and a scaled operating software business positions us for long-term value creation across both digital asset and enterprise analytics markets."

The Numbers Behind the Position

The scale here is worth sitting with for a moment. Strategy's 717,131 BTC is custodied across three regulated third-party custodians: Coinbase Custody holds 287,322 BTC (40% of the position), Anchorage Digital Bank N.A. holds 262,194 BTC (37%), and Fidelity Digital Assets holds the remaining 167,615 BTC (23%). No single custodian holds a majority, which is a deliberate counterparty-risk management decision.

The common equity structure as of February 13, 2026 comprises 314,112,458 Class A shares and 19,640,250 Class B shares outstanding. As of June 30, 2025, the non-affiliate common equity market capitalization — the market value of all shares held by investors other than insiders, a standard measure used to qualify for major index inclusions — was approximately $105.45 billion.

That $105.45 billion market cap against roughly $49.3 billion in underlying bitcoin market value (at the $68,734 filing-date price) implies the stock was trading at a substantial premium to NAV. That premium is not irrational if you believe two things: first, that bitcoin's price will be higher in the future than it is today; and second, that Strategy's capital markets engine will continue operating effectively, allowing the company to acquire even more bitcoin. The premium is, in essence, the market's forecast of future accumulation compressed into today's share price — the same logic that gives a high-growth tech stock a high earnings multiple.

As the 10-K puts it: "We believe that bitcoin is a financial and technological innovation and represents a compelling long-term treasury reserve asset due to its scarcity, durability, and global liquidity."

You can agree or disagree with that belief. But it is worth understanding it clearly before evaluating the thesis.

What Could Break This Thesis

Every structural advantage in Strategy's model has a corresponding structural vulnerability. Four specific failure modes are worth naming directly.

1. Sustained bitcoin price decline below the cost basis. The aggregate cost basis of $54.5 billion ($76,027 per coin average) exceeded the $68,734 market price on the filing date. A prolonged bear market that keeps bitcoin below that average cost raises serious questions about the company's ability to service its fixed obligations — preferred dividends, convertible note interest — and could ultimately force liquidation of some of the bitcoin position to raise cash, creating a destructive feedback loop.

2. Capital markets access drying up. Strategy's entire model depends on continuously issuing new securities — ATM equity, convertible notes, preferred stock. If credit conditions tighten sharply, if equity markets seize, or if investors develop dilution fatigue (a point at which the market refuses to absorb more share issuance at a premium), the accumulation engine stalls. Without new capital inflows, the company cannot buy more bitcoin, and the NAV premium that justifies the current stock price begins to erode.

3. Custodial concentration and counterparty risk. One hundred percent of Strategy's bitcoin is held with three third-party custodians. A serious cybersecurity breach, loss of private keys, or the insolvency of one of those custodians could result in permanent, unrecoverable loss of assets. Diversifying across three firms reduces single-point-of-failure risk but does not eliminate it. There is no FDIC equivalent for bitcoin custody.

4. Regulatory reclassification of bitcoin as a security. If U.S. regulators were to reclassify bitcoin as a security rather than a commodity, Strategy could face obligations under the Investment Company Act of 1940 — a regulatory regime designed for mutual funds that would be extraordinarily difficult to comply with given the company's structure. Such a reclassification would also likely suppress bitcoin's market price broadly, compressing the value of Strategy's entire position simultaneously.

Conclusion

Strategy Inc. has made a bet that most corporate treasurers would not make: that a single digital asset is valuable enough, and scarce enough, to justify restructuring the entire capital architecture of a public company around its accumulation. Whether that bet ultimately pays off depends almost entirely on the long-term trajectory of bitcoin's price — and on Strategy's ability to keep accessing capital markets at favorable terms.

What is already not in doubt is the ambition of the execution. Five new financial instruments in a single year. Three regulated custodians. A $2.25 billion liquidity reserve. A renamed company. These are not the actions of an organization hedging its conviction. As bitcoin's fixed supply approaches its hard cap — only about 1 million coins remain unmined against the 21 million total — Strategy's 717,131 BTC position will represent a permanently larger slice of a permanently fixed pie. The question investors need to answer is whether they believe the pie itself keeps growing in value. If the answer is yes, the logic of everything Strategy is doing follows naturally. If the answer is no, the $54.5 billion cost basis is a very expensive lesson waiting to be learned.
