Due Diligence Capital Notes

Most companies that raise capital have one or two levers to pull — sell some stock, maybe issue some debt. In a single seven-day window during February 2026, Strategy Inc. pulled five levers simultaneously, channeling proceeds from two different securities into 2,486 Bitcoin purchased at an average price of $67,710 each. The transaction was routine by Strategy's standards. That's precisely the point.

The company now holds 717,131 BTC — the largest corporate Bitcoin treasury ever assembled — and still has roughly $37.4 billion in combined At-The-Market (ATM) capacity left to deploy. Understanding what that number actually means, and why it matters far more than any single Bitcoin purchase announcement, is what this post is about.

What Is an ATM Offering, and Why Does Strategy Have Five of Them?

An At-The-Market offering is a mechanism that allows a company to sell shares — or other listed securities — directly into the open market at prevailing prices, rather than through a single large, underwritten block deal. Instead of announcing "we're selling 10 million shares on Tuesday," the company dribbles shares into the market continuously through a registered broker, capturing whatever the market is offering that day.

For most companies, the ATM is a capital-raising tool of last resort, used when the stock is weak and a formal offering would spook investors. Strategy has inverted this entirely. Because its stock and preferred shares trade at a premium to the underlying Bitcoin value — a premium investors willingly pay for reasons I've written about before — every share sold through the ATM generates more Bitcoin-buying power per diluted share than the underlying Bitcoin is worth. The act of selling, paradoxically, can be accretive to the Bitcoin-per-share metric that long-term holders care about.

But here's what's changed over the past year: Strategy didn't stop at one ATM program. As of February 16, 2026, the company has five separate listed securities, each running its own ATM program:

MSTR — Class A common stock, $7,883.7M remaining capacity
STRC — Variable Rate Perpetual Stretch Preferred, $3,542.8M remaining capacity
STRF — Fixed-rate preferred, $1,619.3M remaining capacity
STRD — Another preferred class, $4,014.8M remaining capacity
STRK — Convertible preferred, $20,331.6M remaining capacity — by far the largest runway

Each security appeals to a different investor. Common stock buyers want leveraged Bitcoin upside. Preferred holders want yield with a Bitcoin-adjacent twist. The genius of the multi-security structure is that Strategy can tap whichever pool of capital is most enthusiastic on any given day, at whatever price that market will bear, and immediately recycle the proceeds into Bitcoin.

The Mechanics of a Single Purchase Week

Let me walk through what actually happened during the February 9–16, 2026 window, because the mechanics reveal the machine more clearly than any summary can.

Common stock (MSTR) issuance: Strategy sold 660,000 Class A shares into the open market, generating $90.5 million in net proceeds. Six hundred and sixty thousand shares sounds like meaningful dilution — and mathematically it is — but against a share count in the hundreds of millions, the percentage impact in a single week is modest.
Preferred stock (STRC) issuance: Simultaneously, the company sold 785,354 shares of STRC — the Variable Rate Perpetual Stretch Preferred — generating $78.4 million in additional net proceeds. These are not the same investors. STRC buyers are typically seeking a preferred-dividend income stream with a Bitcoin-backed asset underneath, not the common-stock volatility that MSTR buyers are actively seeking.
Combined proceeds: $90.5M + $78.4M = $169.0 million, almost exactly matching the $168.4 million spent on Bitcoin. As the 8-K filed February 17, 2026 states plainly: "The bitcoin purchases were made using proceeds from the sale of shares under the ATM."
Bitcoin acquired: 2,486 BTC at an average of $67,710 per coin. Strategy's cumulative holdings now stand at 717,131 BTC, acquired at a total cost of $54.52 billion, implying a portfolio-wide average purchase price of $76,027 per BTC.

That last number deserves attention, and I'll return to it in the risk section.

Why $37.4 Billion in Remaining Capacity Is the Real Headline

Every individual Bitcoin purchase announcement gets its own press cycle. But the number that tells you where this is actually going is the aggregate remaining ATM capacity: approximately $37.4 billion across the five securities as of mid-February.

To put that in context: Strategy has already spent $54.52 billion accumulating its current hoard. The remaining authorized capacity represents roughly 69% of the total historical spend, sitting in reserve. And the breakdown matters enormously here.

STRK's $20.3 billion in remaining ATM capacity is the dominant figure. STRK is a convertible preferred stock — meaning holders receive a preferred dividend (8.00% annualized) and, under certain conditions, can convert their shares into MSTR common stock at a predetermined price. For investors who want Bitcoin exposure but can't stomach common-stock volatility, it offers a middle path. For Strategy, it's another entry point into a massive pool of capital that traditional equity issuance can't easily access.

The remaining $17.1 billion spread across MSTR, STRC, STRD, and STRF gives management enormous tactical flexibility. On any given week, they can weight issuance toward whichever security is trading most favorably. If common stock sentiment is soft but preferred buyers are hungry for yield, they lean on STRC or STRD. If the market is exuberant about Bitcoin and MSTR is trading at a stretched premium, common stock issuance becomes the dominant channel.

This is the flywheel. Capital raises fund Bitcoin purchases. Bitcoin holdings (theoretically) appreciate. Rising Bitcoin value inflates MSTR's apparent NAV, which supports higher stock and preferred prices. Higher prices make future ATM issuance more capital-efficient. Repeat.

Strategy even maintains a real-time disclosure dashboard on its website per the Regulation FD disclosure in the same 8-K: "Strategy also maintains a dashboard on its website (www.strategy.com) as a disclosure channel for providing broad, non-exclusionary distribution of information regarding Strategy to the public, including information regarding market prices of its outstanding securities, bitcoin purchases and holdings, certain key performance indicator metrics and other supplemental information." That's an unusual but deliberate transparency choice — one that seems designed to keep the information asymmetry as low as possible and sustain market trust in the ongoing program.

What Could Break This Thesis

I'd be doing you a disservice if I left the flywheel description there without naming the specific scenarios where it stops spinning.

1. The cost basis problem. Strategy's portfolio-wide average purchase price is $76,027 per BTC. During this specific February window, they were buying at $67,710 — meaning the period acquisitions came in below the portfolio average, which is marginally better than the alternative. But if Bitcoin were to stabilize or decline from here, Strategy's cumulative $54.52 billion position would be underwater. A portfolio sitting at a loss isn't necessarily fatal — as long as no one forces a sale — but it would erode confidence in the accretion narrative that supports the NAV premium.

2. The dilution treadmill. Every ATM issuance creates new shares (or preferred units) that represent claims on the company's assets. Common shareholders are continuously diluted in nominal terms. The bet is that Bitcoin appreciation outpaces the dilution. If it doesn't — if Bitcoin stagnates while the share count keeps growing — BTC per share declines, and the core value proposition deteriorates.

3. Preferred dividend obligations. STRF and STRD carry fixed 10.00% annual dividend rates, and STRK carries 8.00%. These are real cash commitments that compound as ATM issuances increase. At scale, they represent a meaningful and growing fixed expense that persists regardless of what Bitcoin does. A prolonged bear market doesn't eliminate these obligations; it just makes them harder to service.

4. Concentration and liquidity risk. There is no second asset here. Strategy has essentially 100% of its investment capital in a single, highly volatile, 24/7 traded asset with no earnings, no cash flows, and no intrinsic value floor beyond collective belief. A severe and sustained Bitcoin drawdown — say 60-70% from peak, which has happened twice in the last decade — would simultaneously impair the portfolio value, crush the ATM premium, and call into question whether preferred dividends can be sustained. The five-security flywheel runs beautifully in a bull market. In a deep, multi-year bear market, it runs in reverse.

Conclusion

Seven hundred and seventeen thousand Bitcoin. Thirty-seven billion dollars of authorized capital machinery still loaded and ready to fire. These are not incremental numbers — they describe a company that has structurally committed itself to one of the most concentrated, high-conviction balance-sheet bets in the history of public markets.

What strikes me most about the February 9–16 window isn't the 2,486 BTC acquired — that's almost a rounding error on a 717,131 BTC position. It's the dual-security, simultaneous issuance: common shares and preferred shares, two investor communities, one Bitcoin purchase, executed as a matter of operational routine. The machinery is no longer novel. It's been institutionalized.

Whether that's reassuring or alarming probably depends on your view of Bitcoin's next decade. For those who believe — as management clearly does — that BTC will trade multiples higher over a long enough horizon, the $37.4 billion in remaining ATM firepower looks like extraordinary optionality. For skeptics, it looks like a highly leveraged position growing more concentrated with every passing week. The data doesn't resolve that disagreement. It only makes the stakes clearer.
