MSTR common doesn't owe anyone anything. That's not the boring half of the story — it's the half that lets the rest run.
MSTR common — the lever
that does two jobs at once
The preferreds are the story. The common is how Strategy buys time. Every share of common sold at a market price above the per-share BTC NAV is accretive for existing holders — and at the same time, delevers the preferred stack, freeing headroom to issue more preferreds when their prices come back.
mNAV: market cap divided by BTC NAV
Strategy's BTC NAV is how much its Bitcoin pile is worth in dollars today. Its market cap is how much the public market values the company — the share price times shares outstanding. mNAV is the ratio.
When mNAV = 1.0, the market values one MSTR share at exactly its share of the BTC stack. When mNAV = 1.5, the market is paying 1.5× — a 50% premium for the machine wrapped around the BTC. When mNAV < 1, the market is discounting the wrapper.
MSTR has traded above 1 essentially the whole life of the strategy. The premium is the market saying: "the wrapper itself adds value" — through ongoing accretion, leveraged exposure for tax-deferred accounts, the option value of future financing, etc. That premium is the engine of the common-ATM half of the mechanism below. The preferred-ATM half is gated on something different — pref market price vs par, not mNAV — so it keeps running even when mNAV slips. See the mNAV page for the full two-channel picture.
Every common ATM above mNAV = 1 is accretive
The math is one line of arithmetic, but it's the line that explains why Strategy keeps printing shares.
Suppose one share currently backs B
BTC of NAV at price P.
The share's BTC-side value is B × P.
If MSTR trades at market price M, then
mNAV = M / (B × P).
Strategy issues one new share at price M
and uses every dollar to buy BTC at P.
That buys M / P BTC. The pile is
now bigger by exactly that much, and there's one more share to divide
it across.
New BTC per share = (B × old_shares + M / P) / (old_shares + 1).
That's greater than the old B
whenever M / P > B, i.e.
M > B × P. Which is just
mNAV > 1.
Read that again: any sale of common at any market price above the per-share BTC NAV adds BTC to every existing share. Not neutral. Not "depends on conditions." Strictly accretive, by definition, every time. The amount of accretion scales with how far above 1 the mNAV is — a sale at 1.01 is barely accretive, a sale at 2.0 doubles the BTC bought per share-of-dilution. But the sign is fixed: positive, always, above par.
The flip side is also clean: at mNAV < 1, common ATMs are dilutive — the cash you raise from a new share doesn't buy back as much BTC as that share's claim already represented. That's why Strategy stops the program when MSTR trades below NAV.
Common ATMs make room for more preferreds
Strategy's preferred stack is fixed-claim debt-like obligation. The common isn't. Issuing common raises total enterprise value without adding any preferred liability. So the preferred-leverage ratio drops.
Mechanically: take the ratio
preferred notional / total enterprise value.
Issuing common stock at any price raises the denominator and leaves
the numerator alone, so the ratio falls. Strategy has internal limits and
rating-agency tolerances on how high that ratio can go. Every common ATM
bleeds off pressure from those limits.
When a preferred series — STRC most often — comes back to a price that's attractive to ATM (near or above $100 par), Strategy can issue more of it without breaching the leverage limit, because common ATMs in the meantime have made the headroom. The two programs trade off: when preferreds are ATMable, Strategy raises preferred capital (which captures the par-vs-market spread); when preferreds aren't ATMable, Strategy raises common capital (which is accretive AND rebuilds the headroom for the next preferred run).
When each lever pulls
| Conditions | What Strategy ATMs | Why |
|---|---|---|
|
High mNAV (>> 1.0), prefs near or above par |
Both — common heavily, preferreds opportunistically. | Best of both worlds: high common accretion, plus pref ATMs capture the par-premium spread before it closes. |
|
Modest mNAV (just > 1.0), prefs below par |
Common only. | Even a small accretion is positive, AND the common ATM delevers the prefs — building headroom for when their prices recover. |
|
High mNAV, prefs far below par |
Common only — wait on prefs. | Issuing prefs below par locks in a bad cost of capital for a perpetual liability. Better to wait, ATM common in the meantime, and rebuild leverage room. |
|
mNAV < 1, at least one pref near par |
Pref only (typically STRC, since its variable rate keeps it close to $100 by design). Common paused. | Common ATM is dilutive at mNAV < 1, but pref ATM at par isn't gated on mNAV at all — the cash raised buys BTC without diluting common. BTC-per-share keeps growing, slower than State A but still positive. |
|
mNAV < 1, all prefs far below par, leverage maxed |
Neither — pause both programs. | Both gates closed simultaneously. Wait it out, possibly buy back common. The convertible-note channel can still fund BTC purchases without diluting any share count. |
This week's tranche
June 1, 2026: Strategy bought -32 BTC for $-2.0M, funded via Unknown. This week's funding source does not include common ATM; it came from preferreds and/or other instruments instead.
The general pattern Strategy has signaled: common ATM is the workhorse, used essentially every week the math allows. Preferred ATMs are opportunistic, used in bursts when the specific series is at or above par. The "below par → no ATM" discipline is what makes the preferred coupon math survive long-term — issuing below par locks in too high a cost of capital on a perpetual instrument.
