Due Diligence Capital Notes

Most companies that find themselves sitting on a cost basis above the current market price of their primary asset slow down or stop buying. Strategy just deployed $1 billion in a single week to do the opposite.

Between April 6 and 12, 2026, Strategy Inc. acquired 13,927 BTC at an average price of $71,902 per coin — while its all-time average acquisition price across its entire treasury sits at $75,577 per coin. In other words, the company is buying at a discount to its own historical average, and it did so entirely without touching its balance sheet cash or issuing traditional debt. The entire $1 billion came from selling shares of a preferred stock called STRC through an At-The-Market (ATM) offering — a capital mechanism that most retail investors have never heard of, yet one that is now the primary engine powering the largest corporate Bitcoin treasury on earth.

How the STRC ATM Works — And Why It Matters

To understand what Strategy is doing, you need to understand three interconnected concepts: preferred stock, ATM offerings, and how selling one to buy the other can be accretive (value-adding) for long-term shareholders.

Preferred stock is a security that sits between a bond and a common stock. Preferred shareholders get paid before common shareholders in bankruptcy, and they typically receive a fixed or variable dividend. In exchange, they usually give up voting rights and most of the equity upside. STRC is Strategy's variable-rate preferred series — the dividend adjusts based on market conditions, making it attractive to a different set of institutional buyers than the fixed-rate STRF (which pays 10%) or STRK (which pays 8%).

An ATM offering is a mechanism that lets a company sell new shares gradually into the open market at prevailing prices, rather than in a single large block (which would crater the price). The company files a shelf registration with the SEC, designates a broker, and then drips shares into the market across days or weeks. For Strategy, the ATM is not a one-time event — it is a permanent, continuously replenished capital machine.

The critical strategic insight is the arbitrage between what Strategy sells and what it buys. When Strategy sells STRC preferred stock, it is accessing capital from investors who want a yield-bearing, liquid Bitcoin-adjacent instrument. When it turns around and buys Bitcoin with those proceeds, it converts a yield-seeking investor's dollars into scarce, non-yielding, appreciating collateral. If Bitcoin appreciates faster than the dividend cost of the preferred, common shareholders benefit from the spread.

The Mechanics of This Week's Accumulation

Here is exactly what happened between April 6 and April 12, 2026, broken into its component parts:

Capital raise: Strategy sold 10,028,363 shares of STRC preferred stock through its ATM, generating $1,001.3 million in net proceeds. That is roughly $99.85 per share — a notable figure because it means the market is pricing STRC near par, reflecting genuine demand from income-oriented institutional buyers.
Bitcoin acquisition: Those proceeds were deployed immediately to purchase 13,927 BTC at a weekly average price of $71,902 per coin. As the 8-K filed with the SEC on April 13, 2026 states plainly: "The bitcoin purchases were made using proceeds from the sale of shares under the ATM." There is no ambiguity about the funding source.
Treasury milestone: This purchase brought Strategy's total Bitcoin holdings to 780,897 BTC as of April 12, 2026, at an aggregate all-in cost of $59.02 billion. To put that number in context, Strategy now holds roughly 3.7% of the entire Bitcoin supply that will ever exist.
Buying below average: The weekly purchase price of $71,902 is approximately $3,675 below the company's all-time average cost of $75,577 per coin. Every coin bought this week is bringing that average down — a phenomenon sometimes called dollar-cost averaging (DCA) into weakness, which is exactly what a conviction-driven accumulator does when prices soften.

The Remaining Firepower Is Enormous

What makes this week's purchase more interesting than the headline number is the context of what remains available. Strategy is not near the end of its capital-raise runway — it is arguably near the beginning of a freshly expanded one.

On March 23, 2026, Strategy announced two massive ATM increases: a new $21.0 billion STRC offering and a new $21.0 billion MSTR common stock offering. The 8-K describes this expansion directly: "On March 23, 2026, Strategy announced, among other things, a new $21.0 billion offering of STRC Stock (the STRC Increase) and new $21.0 billion offering of MSTR Stock (the MSTR Increase)."

As of the April 13 filing, here is the remaining ATM capacity across all five securities:

Security	Remaining ATM Capacity
MSTR common stock	$27,096.1 million
STRC preferred (variable)	$21,642.6 million
STRD preferred (10%)	$4,014.8 million
STRK preferred (8%, convertible)	$2,100.0 million
STRF preferred (10%)	$1,619.3 million
Total	~$56.5 billion

$56.5 billion in remaining dry powder, across five different securities targeting five different investor constituencies. The common stock ATM targets equity investors who want leveraged Bitcoin exposure. STRC targets yield-seekers comfortable with a variable rate. STRF and STRD target conservative income investors who want a fixed 10% dividend. STRK targets investors who want yield plus a long-dated conversion option into MSTR common stock.

What Saylor has built is not just a Bitcoin treasury — it is a capital-market funnel that converts demand from nearly every corner of the fixed-income and equity markets into Bitcoin accumulation. That is a genuinely novel financial construction, and the March 23 ATM increases suggest the company intends to keep that funnel wide open.

Why Preferred-Stock ATMs Are Particularly Clever

I want to spend a moment on why using preferred stock — rather than common stock — to fund Bitcoin purchases is strategically meaningful for common MSTR shareholders.

When Strategy sells new common shares through an ATM, it creates dilution (more shares outstanding, each representing a smaller slice of the company) alongside accumulation (more Bitcoin per share if the purchase is accretive at the current NAV multiple). The net effect on existing common shareholders depends entirely on whether the premium at which MSTR trades justifies the new shares issued.

When Strategy sells preferred stock instead, the dilution to common equity is zero in the short term. The preferred holders are a separate class. They get their dividend; Strategy gets the cash; Bitcoin gets bought. Common shareholders sit above the fray, benefiting from the Bitcoin accumulation without their ownership percentage shrinking immediately. The cost, of course, is the dividend obligation that preferred holders are owed — which I will address in the risk section below.

This is why the STRC ATM is such an efficient tool in a week like this one. Strategy raised $1 billion, bought 13,927 BTC, and left its common share count untouched.

What Could Break This Thesis

No honest analysis of Strategy skips this section. There are four specific failure modes I watch closely.

1. Sustained Bitcoin price decline below cost basis. Strategy's all-in cost is $75,577 per coin across 780,897 BTC — a total outlay of $59.02 billion. If Bitcoin falls and stays materially below that level, the company faces impairment charges (accounting write-downs that reduce the book value of the Bitcoin holdings to current market value). This doesn't force a sale, but it pressures the balance sheet and could rattle the confidence of preferred shareholders whose security rests on that asset base. The recent purchase at $71,902 is already below the average cost basis, which means the portfolio is currently slightly underwater on a cost-vs-market basis.

2. Preferred dividend obligations becoming a cash drain. STRF pays 10%, STRD pays 10%, STRK pays 8%, and STRC pays a variable rate. As Strategy continues to issue preferred stock at scale, the cumulative quarterly dividend obligation grows. Bitcoin does not generate cash flow. If the company ever needs to service these dividends in a prolonged BTC bear market and cannot issue new securities at acceptable terms, the preferred dividend stack becomes a serious liability.

3. Dilution fatigue across all five ATM channels. With $56.5 billion in remaining ATM capacity, Strategy has the legal authority to issue a staggering amount of new securities. If market appetite for MSTR common, STRC, STRF, STRK, and STRD simultaneously weakens — for instance, if Bitcoin sentiment turns sharply negative — all five ATM channels could seize up at once. The accumulation machine requires continuous market demand for its securities to function.

4. Regulatory disruption. The entire strategy rests on the SEC's current tolerance for preferred-stock ATM structures used to fund volatile-asset purchases and on the broader regulatory treatment of corporate Bitcoin treasuries. New SEC guidance on how companies account for or disclose Bitcoin holdings, or targeted scrutiny of the preferred-stock ATM structure, could materially impair Strategy's ability to raise capital through these channels.

Conclusion

A billion dollars of Bitcoin purchased in a single week, funded entirely by preferred stock sales, from a company that still has $56 billion in remaining ATM capacity. Whatever your view on Bitcoin, the mechanical elegance of what Strategy has assembled is hard to dismiss.

The piece I find most forward-looking is the March 23 ATM expansion — the simultaneous addition of $21 billion in new STRC capacity and $21 billion in new MSTR capacity. That is not a company managing a position. That is a company reinforcing an infrastructure for accelerated accumulation. The question I am watching now is not whether Strategy will keep buying — that answer is obvious — but whether the premium at which MSTR trades continues to justify the pace of preferred issuance as the Bitcoin treasury grows toward the 1-million-BTC threshold that Saylor has publicly discussed as a long-term target. At 780,897 BTC today, that target is closer than it has ever been.
