Introduction
Strategy (formerly MicroStrategy) has crafted a distinctive capital structure, blending various debt and equity instruments to fund its operations and, most notably, its Bitcoin acquisitions. In simple terms, capital structure refers to the mix of debt and equity a company uses to finance its growth. What makes Strategy’s case particularly interesting is the introduction of multiple innovative financial instruments, including common stock, preferred stocks like STRK and STRF, convertible bonds, and now, the newly launched STRC.
The latest addition, STRC (Stretch), is particularly intriguing. Marketed as a "stable" Bitcoin-backed equity, STRC aims to mimic the stability of a T-bill, offering a low-volatility, cash-like yield layer within Strategy's BTC credit stack.
This article will break down these layers in simple terms, explain what STRK, STRF, and STRC are and how they work.
Capital Structure Basics
Think of a company’s finances as a layered cake or pyramid. Each layer represents a different type of capital with its own risk and reward:
- Senior Debt (Loans/Bonds) – This is the top layer (think of first-class on an airplane or the first slice of cake). Debt investors (like bondholders) get priority. They loan money to the company and expect repayment with interest. If the company goes bust, these creditors must be paid back before any stockholders get anything. Debt is typically lower-risk (secured by assets or senior in claim) but offers fixed, limited returns (interest).
- Preferred Stock (Preferred Equity) – This sits between debt and common stock in the capital stack. Preferred shares are like a hybrid: they usually pay a fixed dividend (like interest) and have priority over common stock for payments, but they generally don’t have voting rights. In a metaphor, preferred investors are a “preferred” boarding group – not as senior as first-class (debt) but they board before economy class (common equity). Preferred stock returns are more predictable (fixed dividends) and the price tends to be more stable than common stock, but there’s usually less upside if the company’s value soars. Importantly, if the company is liquidated, preferred holders have a claim to get their money (up to a set amount) before common shareholders do.
- Common Stock (Equity) – This is the bottom layer of the cake (or the last to board the plane). Common shareholders are the owners of the company. They get whatever is left after all other obligations are met. This means highest risk (in a bankruptcy, common stock often gets nothing), but also highest potential reward (if the company thrives, common stock can skyrocket with no cap). Common stockholders usually have voting rights and benefit the most from long-term growth, but they are last in line for claims on assets or cash flow.
In summary, the capital stack is a hierarchy: debt > preferred stock > common stock in terms of claim priority. Each layer has a different risk/return profile suited to different investors. Now, let’s see how Strategy has structured its own capital stack using these ingredients.
Strategy’s Overall Capital Structure Overview
Strategy has deliberately engineered a multi-tier capital structure to fund its strategy of accumulating Bitcoin. As of 2025, the company’s captial stack include:
Common equity – the regular shares of Strategy that trade on Nasdaq under MSTR. These are the ordinary stocks for shareholders who want direct participation in the company’s fortunes (and Bitcoin holdings).
Preferred equity – multiple series of perpetual preferred stock with creative nicknames:
- STRK (“Strike”) – an 8.00% Series A perpetual preferred stock issued in early 2025.
- STRF (“Strife”) – a 10.00% Series A perpetual preferred stock issued in March 2025.
- STRC (“Stretch”) – a 9% annual yield instrument. STRC offers a stable, low-volatility, cash-like option.
- STRD (“Stride”) – a high-yield, junior preferred stock, providing greater risk and reward compared to the other series. STRD is designed for investors seeking higher returns at a higher risk.
Convertible bonds – these are debt instruments that can convert into common shares if Strategy’s stock price reaches certain levels. Strategy has issued several, notably 0% interest convertible notes due in future years (2027, 2028, 2030, etc.) to raise billions to buy Bitcoin.

Think of each layer as a different way for investors to bet on Bitcoin with a profile that suits them:
- Common stock (MSTR) – for investors who want maximum upside (or downside) tied to Bitcoin’s price, since the stock’s value is heavily driven by the value of Strategy’s Bitcoin holdings.
- Preferred stock (like STRK, STRF) – for investors who want income (yield) and some stability, effectively getting a fixed return without the full volatility of owning Bitcoin directly.
- Convertible bonds – for investors who want the safety of a bond (priority claim and a promise of repayment) but also a call option on Bitcoin’s upside (via conversion to shares if the stock soars).
STRC (“Stretch”): The Stable, Cash-Like Layer in Strategy’s Capital Stack
STRC, or “Stretch,” is the latest innovation in Strategy’s capital structure. STRC is a variable-rate, perpetual preferred stock that provides investors with a stable, high-yield opportunity backed by Bitcoin. The instrument is designed to function like a cash-equivalent asset, offering low volatility and regular monthly dividends, while still allowing exposure to Bitcoin’s performance.
Preferred stocks are a special class of stock that have a fixed dividend and priority over common stock for receiving dividends or assets, but usually no voting rights. Strategy’s preferreds are “perpetual” – meaning they have no maturity date (the company isn’t obligated to ever pay back a principal amount; it just pays the dividends indefinitely, unless it redeems the shares).
Key Features of STRC
Yield & Dividends: STRC offers an annual dividend rate of approximately 9%, which is payable on a monthly basis. The dividend rate is adjustable each month, with the aim of maintaining the share price near its $100 stated value. This makes it an attractive option for income-focused investors looking for a stable cash flow without the full volatility of holding Bitcoin directly.
Price Stability Mechanisms:
- Monthly Rate Adjustments: To maintain price stability, Strategy has the ability to adjust the dividend rate each month, ensuring that the price of STRC stays near $100. If the price falls below par, Strategy will increase the dividend, and if the price rises, it will lower the dividend and issue more shares to bring the price back to the target level.
- Issuer Call Option: In the event that STRC trades significantly above its par value, Strategy can redeem shares at $101, plus accrued dividends, providing an additional mechanism to keep the price stable within the target range.
STRC in the Capital Stack
In Strategy’s multi-layered capital structure, STRC occupies a middle tier. It ranks senior to STRD (“Stride”) and STRK (“Strike”), but is junior to STRF (“Strife”) and the company’s debt. This positioning allows it to be a more stable, low-volatility option compared to the higher-risk preferred stocks, while still offering a higher yield than traditional cash-equivalent instruments.
STRC is designed for a variety of investor profiles:
- Credit investors looking for low-volatility, short-duration instruments tied to Bitcoin’s upside.
- Cash managers who want a predictable, steady yield without the exposure to the full volatility of Bitcoin.
- Institutions and allocators who are not yet comfortable holding raw Bitcoin but want to gain exposure to its price movements via a stable, cash-like instrument.
How Strategy May Fund Dividends and Interests?
It’s worth reiterating the company’s plan to service its obligations. Strategy openly states it will use a combination of sources to fund its preferred dividends and any debt interest: operating cash flow (from its software business, which provides some millions in income), proceeds from new debt or convertibles, and proceeds from ATM (at-the-market) sales of common stock.
In 2023–2025, the company had an active ATM equity program, selling small amounts of MSTR stock into the market – for example, it sold stock to raise $500 million in 2023 and had authorization to sell up to $3.57 billion more of common stock as of early 2025. That is a sizable war chest: by issuing new common shares gradually (especially when the stock price is high), they can bring in cash to cover dividends.
Additionally, the launch of new preferred series (like STRD “Stride”) was explicitly to raise money partly to pay the dividends on STRF and STRK. This might seem like paying one credit card with another – and in a sense it is a form of refinancing scheme. As long as new investors are willing to come in (and Bitcoin’s narrative stays strong), it can work. If capital markets froze or the stock price collapsed, it would be much harder for Strategy to raise fresh funds, and that’s where the strain would show.
