Strategy Just Changed How Investors Should Measure MSTR
Strategy has spent years teaching investors to watch one number: Bitcoin Per Share.
The idea was simple. Strategy buys bitcoin. It issues shares and other securities to finance those purchases. If its Bitcoin holdings grow faster than its diluted share count, Bitcoin Per Share rises.
On July 23, 2026, Strategy changed the framework.
The company introduced Net Reserve, Net BTC and Net Bitcoin Per Share, while also redefining mNAV and Amplification and expanding its Bitcoin credit metrics. The update does not replace the old Bitcoin Per Share calculation. It adds a second layer designed to account for the debt and preferred stock that rank ahead of MSTR common shareholders.
That distinction matters because Strategy is no longer just a company holding bitcoin.
It is a Bitcoin treasury built on common stock, convertible debt, preferred stock and a dedicated USD Reserve. Strategy reported 843,775 BTC and a $3.225 billion USD Reserve as of July 19, 2026.
The old metrics focus on how much Bitcoin Strategy owns.
The new metrics focus on how much remains behind MSTR.
The problem with gross Bitcoin Per Share
Strategy’s original Bitcoin Per Share metric divides its total Bitcoin holdings by Assumed Diluted Shares Outstanding.
That share count assumes conversion of all convertible notes and convertible preferred stock, together with outstanding options, restricted stock units and performance stock units. It does so whether the convertible instruments are currently in or out of the money.
The metric therefore accounts for potential dilution.
But it begins with Strategy’s entire Bitcoin reserve.
It does not first deduct the debt and preferred stock claims ranking ahead of common equity. Strategy itself warns that its gross Bitcoin Per Share metrics do not account for liabilities or the preferential rights of preferred shareholders.
That creates an important limitation.
Strategy can issue a senior security, use the proceeds to buy Bitcoin and increase its gross Bitcoin Per Share. The metric records the additional Bitcoin, but it does not deduct the senior claim created by the financing.
This is the gap that Net Bitcoin Per Share is designed to address.
Net Reserve is the new starting point
Net Reserve measures the residual dollar value of Strategy’s Bitcoin and designated USD Reserve after specified senior claims are deducted.
Strategy calculates it by starting with the Bitcoin Reserve, subtracting the notional amount of out-of-the-money convertible notes and other debt-like instruments, subtracting the notional amount of outstanding perpetual preferred stock, excluding in-the-money STRK shares, and adding the USD Reserve.
This is not the same as taking the market value of Strategy’s Bitcoin and subtracting every accounting liability on its balance sheet.
It is a company-defined capital-markets metric built around specific debt and preferred claims.
That makes Net Reserve the bridge between Strategy’s assets and the position of MSTR common shareholders.
Gross Bitcoin Reserve shows the size of the treasury.
Net Reserve shows what remains after the specified capital structure is recognized.
Net BTC converts the adjustments into Bitcoin
Net BTC applies the same senior-claim and USD Reserve adjustments directly to Strategy’s Bitcoin holdings, with the dollar amounts converted into Bitcoin at the applicable Coinbase price.
This is important because Strategy wants investors to evaluate MSTR on a Bitcoin basis, not only through conventional dollar accounting.
The calculation effectively asks:
After accounting for the specified debt and preferred claims, and after adding the USD Reserve, how much Bitcoin-equivalent value remains?
The answer changes with the Bitcoin price, foreign-exchange rates, the amount of debt and preferred stock outstanding and whether convertible instruments are in the money.
Net BTC is therefore not a fixed reserve figure.
It is a point-in-time measurement of the Bitcoin-equivalent value remaining behind the capital structure.
Net Bitcoin Per Share is the central new metric
Net Bitcoin Per Share divides Net BTC by Fully Diluted Shares Outstanding.
This changes both sides of the traditional Bitcoin Per Share calculation.
The numerator changes from total Bitcoin holdings to Net BTC.
The denominator changes from Assumed Diluted Shares Outstanding to Fully Diluted Shares Outstanding.
Fully diluted shares include Strategy’s basic Class A and Class B shares, outstanding equity awards and only the convertible notes and STRK preferred shares that are currently in the money.
Out-of-the-money convertibles are not added to the share count. They remain senior claims deducted from Net BTC.
That prevents the same security from being treated both as debt and as common-stock dilution.
The difference between the two Bitcoin-per-share metrics is therefore fundamental.
Gross Bitcoin Per Share asks:
How much Bitcoin does Strategy own relative to a share count that assumes all convertible securities convert?
Net Bitcoin Per Share asks:
How much Bitcoin remains after specified senior claims are included, divided by the shares that would exist if the currently in-the-money securities converted?
The second calculation is a stricter test of whether Strategy is improving the Bitcoin position behind MSTR.
The share count now reacts to the MSTR price
Strategy’s new framework also makes the MSTR share price part of the calculation.
An instrument may be out of the money at one MSTR price and in the money at another.
When an instrument moves into the money, its treatment changes. Instead of remaining a senior claim deducted from Net BTC, its potential common shares enter Fully Diluted Shares Outstanding.
This means Net Bitcoin Per Share can change even when Strategy buys or sells no Bitcoin.
A movement in MSTR can change which securities are treated as potential common shares and which remain claims against the reserve.
mNAV now uses Net Bitcoin Per Share
Strategy also changed mNAV.
The updated metric divides the MSTR Class A share price by Net Bitcoin Per Share expressed in dollars.
The company states that mNAV before July 23, 2026 referred to a different metric, meaning historical figures calculated under the old methodology are not directly comparable with the new version.
Strategy also warns that its mNAV is not traditional net asset value.
It is not book value, liquidation value or a direct claim on the company’s Bitcoin.
Under Strategy’s assumptions, 1.0x becomes the key reference point.
Above 1.0x mNAV, issuing MSTR common stock and using the proceeds to purchase Bitcoin would generally be expected to increase Net Bitcoin Per Share.
Below 1.0x, the same transaction would generally be expected to reduce it.
The conclusion depends on Strategy’s stated assumptions, including unchanged Bitcoin and MSTR prices, conversion of in-the-money convertible instruments and an immediate hypothetical liquidation in which preferred liquidation preferences are assumed to equal their notional amounts.
The metric is therefore a model, not a guarantee that a completed capital raise was accretive.
Preferred issuance has its own accretion threshold
The new framework also explains why issuing preferred stock is not automatically accretive or dilutive.
The central question is the issuance price relative to the preferred stock’s notional amount.
Strategy states that issuing preferred stock below notional and using the proceeds to buy Bitcoin would generally be expected to reduce Net Bitcoin Per Share.
Issuing it above notional would generally be expected to increase Net Bitcoin Per Share.
That is because Net BTC deducts the preferred stock’s notional claim, not simply the cash Strategy received.
A preferred share sold below its notional amount creates a larger senior claim than the cash raised.
A preferred share sold above notional raises more purchasing power than the notional claim added to the calculation.
This is one of the clearest differences between gross and net Bitcoin metrics.
Gross Bitcoin Per Share mainly sees the Bitcoin purchased.
Net Bitcoin Per Share also sees the claim created to purchase it.
Amplification compares gross and net reserve values
Strategy also redefined Amplification.
The updated formula divides Bitcoin Reserve by Net Reserve.
Bitcoin Reserve is the market value of Strategy’s Bitcoin holdings, calculated using the Bitcoin price. Net Reserve is a company-defined metric that adjusts that market value for specified senior claims and the USD Reserve.
Amplification therefore compares Strategy’s gross Bitcoin market value with its adjusted Net Reserve.
It is not a GAAP balance-sheet ratio, book-value measure or stockholders’ equity measure. Strategy also warns that the notional amounts used for preferred stock can differ from the amounts payable in a liquidation, redemption or repurchase.
If Bitcoin rises while the specified dollar claims remain broadly unchanged, those claims consume a smaller portion of the Bitcoin Reserve and Amplification generally falls.
If Bitcoin falls, they consume a larger portion and Amplification generally rises.
Strategy states only that Amplification before July 23, 2026 referred to a different metric. Earlier Amplification figures are therefore not comparable with figures calculated under the new definition.
Amplification is not a prediction that MSTR will move by a fixed multiple of Bitcoin.
The credit metrics ask how much Bitcoin performance is required
Strategy’s expanded credit framework includes several Bitcoin annual return thresholds.
They have similar names but measure different things.
BTC Hurdle ARR represents Strategy’s effective cost of credit, above which MSTR captures a positive spread.
BTC Breakeven, without ARR in the name, is the Bitcoin annual return required to generate positive Bitcoin-dollar value for a particular financing.
BTC Breakeven ARR is an aggregate company-level ratio. Strategy calculates it as annual interest plus preferred dividends divided by Bitcoin Reserve. At or above that rate, Strategy says Bitcoin capital gains could fund those recurring obligations in perpetuity under the model.
BTC Floor ARR is the lowest constant Bitcoin annual return over the weighted average duration of Strategy’s credit structure that maintains 1.0x coverage of Net Debt and preferred stock through the Bitcoin Reserve after funding interest and preferred dividends throughout the period.
The glossary also includes BTC Escape Velocity, BTC Stall Speed and BTC Credit Hurdle.
Together, these metrics attempt to answer three broader questions:
What does Strategy’s capital cost?
How much Bitcoin appreciation is required to support it?
What constant annual Bitcoin return would preserve Strategy’s defined coverage threshold over the weighted average duration of its credit structure?
They are company-defined analytical metrics, not credit ratings or Bitcoin price forecasts.
Strategy has changed the scoreboard
The July 23 update does not change the number of Bitcoin Strategy owns.
It changes how investors are encouraged to judge the financing behind those holdings.
Bitcoin Per Share remains the measure of gross accumulation.
Net Bitcoin Per Share measures the result after specified senior claims are recognized.
mNAV now compares the MSTR share price with Net Bitcoin Per Share.
Amplification compares gross Bitcoin Reserve with Net Reserve.
The credit metrics estimate the Bitcoin returns required to support Strategy’s financing structure.
This is the real significance of the update.
Strategy’s first phase was about building the largest corporate Bitcoin reserve.
The new metrics are designed for the second phase: measuring whether the capital structure around that reserve is creating value for MSTR common shareholders.
MSTR investors do not directly own Strategy’s 843,775 Bitcoin.
They own the common equity left beneath the financing used to build the reserve.
Strategy’s new metrics are an attempt to measure it.
