Bitcoin Treasury Company

What it is

The defining characteristic is not the presence of bitcoin on the balance sheet but the subordination of the capital structure to it. Many public companies hold some bitcoin. A Bitcoin treasury company organizes financing, disclosure and performance measurement around bitcoin accumulation: it issues securities in order to buy bitcoin, it reports bitcoin holdings and bitcoin-per-share metrics alongside or ahead of conventional operating results, and its equity trades primarily as a function of bitcoin price and the multiple the market assigns to its holdings. True North’s house framing is a public corporation that uses Bitcoin “as a primary treasury reserve asset and as a financing platform,” building an entire capital structure around Bitcoin rather than merely holding it (True North, Digital Credit Glossary).

The population is larger than the two issuers of listed preferred stock. Public trackers counted roughly 196 to 199 public companies holding bitcoin during 2026, with aggregate holdings above 1.24 million BTC, or approximately 5.9% of the 21 million supply (True North Bitcoin Treasury Tracker). Within that population, a much smaller set has built a full financing apparatus: Strategy (Nasdaq: MSTR), the largest corporate holder; Strive (Nasdaq: ASST), which describes itself as a structured finance company and institutional asset manager built around a bitcoin-focused treasury and which completed the acquisition of Semler Scientific in January 2026 (Strive investor relations); Twenty One Capital (NYSE: XXI), which began trading in December 2025 with more than 43,500 BTC (Twenty One Capital press release via SEC EDGAR); and Metaplanet in Japan.

Three structural features distinguish the model from a conventional operating company. First, accounting: under ASU 2023-08, which created ASC 350-60 and became effective for annual periods beginning after December 15, 2024, in-scope crypto assets including bitcoin are measured at fair value each reporting period with changes recognized in net income (KPMG summary of ASU 2023-08). Reported net income therefore swings with the bitcoin price, and a large reported loss is a mark-to-market event rather than an operating outcome; Strategy disclosed an $8.32 billion loss on digital assets for the quarter ended June 30, 2026 under this regime (StockTitan summary of Strategy Form 8-K).

Second, financing mechanics. The characteristic instrument is the at-the-market equity program, supplemented by convertible notes and, for the two digital credit issuers, perpetual preferred stock. The economics of ATM issuance depend on the mNAV multiple: issuing common equity above 1.0x adds bitcoin per share, and issuing below 1.0x subtracts it. Third, valuation convention. These companies are valued on mNAV and bitcoin-per-share rather than on earnings multiples, because reported earnings are a fair-value artifact and operating cash flow is usually immaterial relative to the treasury.

How it is calculated

Bitcoin treasury company is a classification rather than a formula, but four measures define the model quantitatively.

1. Treasury concentration (whether the label applies)

A company whose bitcoin holdings dominate total assets and whose securities issuance is directed at bitcoin acquisition fits the category; one holding an incidental allocation does not. For Strategy, at the Jun 30, 2026 balance-sheet date: digital assets at fair value $49.67B ÷ total assets $52.56B = 94.5%. Both inputs come from the same filing; dividing today’s bitcoin value by a quarter-old asset base would mix vintages.

2. Bitcoin per share

Worked example: 845,050 ÷ 450,112,152 = 0.00188 BTC per share, equivalently 187,742 satoshis per share. The equivalent figure for Strive is 25,000 ÷ 96,523,351 = 0.00025900.

3. Net bitcoin per share, after senior claims

Strategy defines Net BTC as holdings reduced by the notional amount of out-of-the-money convertible notes and other debt-like instruments, plus the notional amount of outstanding perpetual preferred excluding in-the-money STRK, less USD Assets, and divides it by Fully Diluted Shares Outstanding, a count that includes only in-the-money converts and is smaller than ADSO (Strategy, Notes and definitions). Worked example, using ADSO as the share count: (845,050 − ($6.71B + $22.59B − $6.40B) ÷ $75,868) ÷ 450,112,152 = 0.00153.

4. Accretion test for an equity issuance

An at-the-market sale of n shares at price P_s buys nP_s/ P_BTC bitcoin. Bitcoin per share rises if and only if

Worked example: at a share price of $129.60, a bitcoin price of $75,868, and existing bitcoin per share of 0.00188, the issuance is accretive when 0.80× exceeds 1.0. This identity is why mNAV governs treasury-company behavior: it is the break-even condition of the financing model, not merely a valuation observation.

5. Dividend and interest coverage from treasury

Worked example: (845,050 × $75,868 + $6.40B) ÷ ($1.64B + $34.6M) = 42.0 years. Coverage expressed this way assumes assets can be sold at prevailing prices and is highly sensitive to the bitcoin price (True North, Digital Credit Glossary).

Why it matters

For a common-equity investor, the treasury company is a leveraged, actively managed wrapper around a single asset. The wrapper can add value in two ways: by issuing equity above parity to acquire more bitcoin per share, and by accessing financing markets that individual holders cannot, such as convertible debt and perpetual preferred issued at rates below the long-run growth rate of the asset. It can destroy value in two symmetrical ways: by issuing equity below parity, and by taking on senior claims whose fixed obligations must be serviced when the asset price falls. The correct diagnostic is the trajectory of bitcoin per share, not the bitcoin balance in absolute terms, since the latter can grow while the former shrinks.

For a preferred or credit investor, the treasury company is an unusual obligor. Its principal asset is liquid, continuously priced, and produces no cash flow. That means dollar obligations must be met from reserves, operating income, asset sales, or new issuance. Strategy has formalized this with a USD Reserve designated to support preferred dividends and interest, and a separate USD Cash pool for broader purposes (StockTitan summary of Strategy Form 8-K), and it demonstrated the asset-sale channel by selling 3,588 bitcoin to fund digital credit dividends and replenish reserves (Strategy press release, July 6, 2026). Strive discloses a dividend reserve measured in years and a formal deferral-and-cure mechanism that obliges it to use commercially reasonable efforts over 60 days to raise capital covering deferred dividends (Strive Bitcoin Treasury Dashboard).

The sector-level risk is reflexivity. The model depends on equity market access, and equity market access depends on the multiple, and the multiple depends on sentiment toward the underlying asset. When multiples compress across the sector, the financing channel narrows for everyone at once. That is what 2026 demonstrated: the market value of the fifty largest bitcoin treasury companies fell from roughly $150 billion to roughly $67 billion from mid-2025, and a large share of the top 100 traded below the value of their holdings (Startup Fortune, citing Financial Times reporting; Cryptopolitan). A model that is accretive at a premium becomes a buyback-and-conserve exercise at a discount.

Two policy variables sit alongside the market variables. On tax, Treasury and the IRS issued interim guidance on September 30, 2025 clarifying that a corporation may disregard unrealized gains and losses on digital asset holdings when computing adjusted financial statement income for the corporate alternative minimum tax, removing a material contingent liability for large holders (Wall Street Journal live coverage). On index inclusion, MSCI announced on January 6, 2026 that it had “determined at this time not to implement the proposal to exclude digital asset treasury companies” from its Global Investable Market Indexes, and continues to maintain a list of such companies (MSCI consultation results announcement; MSCI index consultations). Both determinations are revisable, and both materially affect the cost of capital of the model.

Key distinctions

• Holding bitcoin does not make a company a Bitcoin treasury company. The category requires that bitcoin be the principal treasury reserve asset and that financing decisions be organized around accumulating it, not that some bitcoin appear on the balance sheet.
• A Bitcoin treasury company is not a fund or an ETF. It is an operating corporation with a board, discretion over capital allocation, senior claims ahead of shareholders, and no redemption mechanism, so its shares can and do trade away from the value of the underlying holdings indefinitely.
• Shareholders do not own specific coins. Common stock is a residual claim on the enterprise after debt and preferred stock; there is no segregated or pledged bitcoin backing the equity.
• “Digital asset treasury company” (DAT) is broader than “Bitcoin treasury company.” DAT is the index-provider and press term encompassing treasuries in any digital asset; the Bitcoin-specific category excludes companies whose reserve asset is another token (MSCI).
• Reported net income is a fair-value artifact. Under ASC 350-60 bitcoin is marked to fair value through net income each period, so large reported gains or losses reflect price movement rather than operating performance (KPMG).
• Growing total bitcoin is not the same as growing bitcoin per share. A company can add coins while diluting existing holders if the acquisition is funded by equity issued below parity.
• Selling bitcoin to fund dividends is a liquidity operation, not necessarily a strategy reversal. It converts treasury into the dollars required to satisfy senior obligations, and it has been used explicitly for that purpose (Strategy press release, July 6, 2026).
• Custody model differs from direct holding. Corporate treasuries generally use qualified third-party custodians, which introduces custodian, counterparty and operational risk that self-custody does not, while removing the operational burden from the individual holder.
