From Convertibles to Cumulative Preferreds: A New Chapter in the MicroStrategy Playbook

The headline is simple; the engineering isn’t. MicroStrategy—already the world’s most visible corporate Bitcoin balance sheet—has filed to issue 3.5 million euro-denominated perpetual preferred shares, each with a €100 par and a 10% cumulative cash dividend. At list, that implies up to €350 million in gross proceeds and €35 million per year in contracted cash payouts before fees and FX translation effects. Management says the proceeds will support additional BTC acquisitions and general corporate needs. The message is unmistakable: the company is still leaning into a balance-sheet strategy where the scarce digital asset is the core treasury reserve, not a sidecar.

Investors have seen several iterations of this thesis: unsecured convertibles at low coupons in the 2020–2021 rate regime; later, higher-coupon notes as policy tightened; at times, at-the-market (ATM) equity raises against elevated valuations. A euro perpetual preferred is a different animal. It looks like equity in that it has no maturity, sits junior to debt, and can absorb losses; it feels like debt because its cash dividend is contractual, cumulative, and senior to common dividends and buybacks. In other words, it can be an elegant way to raise long-dated capital—if you are certain you can carry the annual cash cost through crypto’s inevitable storms.

What a Euro Perpetual Preferred Actually Buys You

Perpetuals remove the refinance cliff. In exchange, you accept ongoing cash servicing and an instrument that outranks the common when it comes to distributions. The euro denomination introduces an additional variable: FX risk. If the firm reports in USD and earns most revenues in USD, paying a fixed euro coupon means your real cash cost in dollars fluctuates with EUR/USD. That can help or hurt: a strengthening dollar reduces the USD outlay; a strengthening euro increases it. Because BTC is priced and settled in USD on most venues, your asset side is dollar-sensitive; your liability side, in this instance, is euro-sensitive. That mismatch deserves board-level attention.

There are remedies. Treasury desks can run vanilla FX hedges (for example, staggered EURUSD forwards that roll quarterly) to convert euro coupon exposure back into synthetic USD. Hedges cost money and management time, but they trade a potentially large P&L swing for a known cost. If your core thesis is that BTC appreciates at a multi-year drift that dwarfs a few points of hedge carry, the insurance is worth considering—particularly if a spike in EURUSD and a BTC drawdown arrive together.

Why Not Just Sell More Common?

Issuing common is the blunt instrument. It dilutes immediately and entirely, and it tells the market you are comfortable monetizing your equity’s valuation here and now. A preferred accomplishes two subtler goals. First, it keeps common dilution conditional: unless explicitly convertible, preferred does not expand the common share count; it only primes it by sitting ahead of common for future distributions. Second, if structured thoughtfully, the preferred can broaden the investor base—income funds and hybrid capital specialists that are not natural buyers of high-beta tech or Bitcoin proxies may still buy a 10% cumulative preferred with strong covenants and clear asset coverage.

From the issuer side, a preferred at 10% also telegraphs internal confidence: “We will generate enough cash—through operations, prudent hedging, and balance-sheet management—to cover a high dividend while compounding in BTC.” Of course, the market can interpret the same message as aggressive: “You are paying a lot for capital; do you really need more bitcoin now?” As usual, the truth lives in the footnotes—the mechanics that make the structure survivable when the path turns ugly.

The Balance Sheet Today: Size, Profit, and the Temptation to Press

By management’s count, MicroStrategy holds ~641,205 BTC, with a market value in the mid-tens of billions (roughly $66B at the prices referenced by the company) and a cumulative investment profit that they frame around ~$19B after a five-year campaign. The scale creates its own gravity. Every incremental financing decision is now measured not just against WACC and near-term dilution, but against the option value of getting to the next plateau of ownership. A fresh €350M—if fully raised and swapped into BTC—translates to roughly 3,200–3,600 additional coins depending on the entry band and FX rate (e.g., at €350M, EURUSD 1.07, and BTC between $105k–$115k). At the low end that’s less than 1% incremental to the stack; at the high end, still under 1%. The arithmetic underscores the intent: this isn’t about massively changing the numerator; it’s about maintaining cadence—continuing to be a programmatic buyer through cycles so the compounding machine never idles.

Cost of Capital vs Expected Drift: The Core Equation

The core finance question is boring and profound: does the expected multi-year BTC drift (price appreciation plus any conservative carry overlay) exceed the all-in cost of capital on the preferred? If the coupon is 10% in euros and you hedge FX at, say, 1–2% annualized, and the underwriting/maintenance fees add another point, your all-in cash cost might land near 11–13% before taxes. Your hurdle is therefore a mid-teens total return on the BTC sleeve or a slightly lower return if operating cash flows shoulder part of the dividend. In buoyant regimes, that looks trivial; in sideways or choppy periods, it becomes the coin-flip that separates elegance from regret.

Because the dividend is cumulative, if you skip a payment you don’t erase the obligation; you stack it. Moreover, cumulative arrears often lock the issuer out of paying common dividends or buying back stock until the arrears are cured. That can be acceptable if your shareholder base values BTC accumulation over cash returns. But it reduces financial policy flexibility just when flexibility is most precious. High-beta treasuries must therefore pre-fund a dividend reserve and set hard tripwires for when to slow or pause BTC purchases so that servicing the preferred never competes with survival.

Seniority, Covenants, and the Survival Hierarchy

Preferred sits between debt and common. It doesn’t usually have a maturity wall, but it often comes with protective provisions: limits on new debt, restrictions on asset sales, approval rights on issuing senior or parity preferred, and remedies when dividends are in arrears. Those covenants can be a feature or a bug. They are a feature in that they discipline management; they are a bug if they constrain opportunistic financing at the bottom or force asset sales at inopportune moments. When your core asset is volatile and largely non-productive (BTC doesn’t pay a coupon), the wrong covenant package can turn a routine drawdown into a capital-structure drama.

Best practice for crypto-treasury issuers is to negotiate cure periods, soft covenants that tighten only at high arrears thresholds, and clear disclosure so the market understands exactly how many euros per quarter must go out the door before any other discretionary capital action. In return, preferred investors should demand reporting transparency: periodic fair-value marks, LTV-style coverage metrics versus net unsecured liabilities, and a defined waterfall for proceeds if the issuer meaningfully de-risks.

FX: The Quiet Risk That Feels Small—Until It Isn’t

Paying a 10% euro coupon from a USD-centric operation means you are running two big macro exposures: BTCUSD and EURUSD. In isolation, each is manageable. Together, they can compound pain in rare but real scenarios: imagine BTC down 35% while the euro rallies 12% versus the dollar; your asset shrinks while your cash obligation in dollars grows. The antidote is dull: maintain an FX hedge book large enough to immunize 12–24 months of dividends, ladder maturities, and revisit the program quarterly. Most of the time, the hedge will feel like a pebble in your shoe—mildly annoying. Some day, it could be the thing that saves the campaign.

Accounting Optics: Fair Value Helps, but Doesn’t Eliminate Volatility

Under evolving U.S. accounting guidance, fair-value treatment for certain digital assets reduces the old asymmetry where impairments were recognized while upward moves were ignored. That is a net positive for issuers like MicroStrategy because reported P&L can now reflect the two-way nature of BTC. Still, fair value simply exposes volatility more cleanly. Rapid drops will show up in reported results just when your cash dividend is due. Boards must be comfortable communicating this duality: accounting volatility is the price you pay for long-term treasury optionality, not a verdict on operational health.

Scenario Modeling: When a 10% Preferred Is Genius—and When It Isn’t

1) Bear/Sideways Case (Probability 30–35%)

BTC spends the next 18–24 months rotating 80k–120k, with no decisive trend. The preferred is fully placed; the company swaps proceeds into BTC methodically. Annual euro dividends (~€35M) are serviced from operating cash flow and a modest carry overlay (e.g., conservative basis trades or covered calls in small size). FX hedging costs 1–2% annually. Reported P&L is choppy; equity investors debate whether financial engineering crowds out core software growth. Outcome: the structure is survivable if the dividend reserve was pre-funded and covenants are light. It is mediocre if the firm must periodically slow BTC purchases to protect cash.

2) Base Drift Case (Probability 45–50%)

BTC establishes higher lows and trends toward 140k–180k into 2027, with the usual 25–35% pullbacks. The company’s weighted all-in cost on the preferred (coupon + FX + fees) stays near 11–12% in USD terms; realized BTC drift surpasses that hurdle, and periodic revaluation gains support optics. The preferred becomes a structured equity instrument that broadened the investor base without immediate common dilution. Outcome: the instrument looks smart, particularly if the firm used FX hedges to avoid procyclical cash drag during a euro rally.

3) Convex Upside Case (Probability 15–20%)

ETF distribution deepens, corporate balance sheets follow, and sovereign vehicles tiptoe in. BTC prints 200k+ with two sharp but brief pullbacks. The preferred coupon is easily carried; the equity re-rates on treasury gains and operating leverage; the market begins to treat the preferred as a yieldy surrogate for participation in the treasury. Outcome: management is celebrated for foresight. The lesson is the same as the bear case: survival mechanics—not vision—decide who makes it to this ending.

Microstructure Matters: Don’t Let a High Coupon Dictate Your Tape Behavior

When you owe a cash dividend every quarter, there is a dangerous temptation to trade the asset to manufacture cash. That is how treasuries end up selling lows and buying highs. The healthier playbook is strict pacing: dollar-cost average entries, pre-define pause conditions (e.g., if realized volatility doubles, stop buying and build cash), and never let a quarterly dividend deadline force you into tapping BTC at disadvantageous prices. If the market senses you are a predictable seller to meet a coupon, it will tax you.

What This Signals to the Market

The signal is two-part. First, MicroStrategy is willing to pay double-digit cash yields in a foreign currency to keep its BTC flywheel turning. That is conviction and audacity. Second, the firm is telling the market that it sees a broader investor base—income and hybrid capital buyers—willing to underwrite the strategy at 10% with cumulative protections. If that investor base materializes at acceptable terms, the company will have demonstrated something profound: that Bitcoin treasury optionality is financeable across cycles, not just in ZIRP.

Key Metrics to Watch After Pricing

• Placement quality: Which funds bought the preferred? Are they sticky hybrid-capital specialists or fast money?
• FX policy: Does the company disclose an explicit hedge program with laddered coverage for 12–24 months of coupons?
• Dividend reserve: How many quarters of cash dividends are pre-funded at close?
• BTC purchase cadence: Does management keep buying methodically, or do they ‘chase’ strength and pause at lows?
• Covenant lightness: Are there soft or hard tripwires that could constrain opportunistic financing during volatility spikes?

For Other Corporates Eyeing the Blueprint

If you are a CFO contemplating a similar move, copy the process, not the optics. Start with risk budgeting: size the preferred so that coupons are comfortably serviced from operating cash even in downside sales scenarios. Create a ring-fenced reserve for at least four quarters of dividends. Run an FX hedge if the instrument is not in your reporting currency. Codify a treasury pacing policy that removes emotions from monthly BTC purchases. Finally, disclose honestly: investors can accept volatility; they punish surprise.

The Counter-Case: Why Skeptics May Still Be Right

Skeptics will argue that paying 10% for capital to buy a non-income-producing, high-volatility asset is definitionally speculative—that the strategy works until it doesn’t, at which point the cash coupon becomes a millstone that crowds out R&D, sales hires, and product investments. They will point to 2022, when mark-to-market losses looked enormous on paper; they will warn that euro strength could blindside the cash budget; they will worry that a cumulative preferred ties management’s hands precisely when flexibility is needed. None of those concerns are irrational. They are the very reasons the design must be conservative: fat buffers, clean hedges, boring covenants.

Bottom Line

MicroStrategy’s proposed 10% euro perpetual preferred is neither a stunt nor a mere press release. It is a statement about the maturing market for Bitcoin-backed corporate finance: investors will fund a cumulative yield, in size, to underwrite a levered digital-asset treasury—if they believe the issuer can survive the path. With ~641k BTC already on the balance sheet and a multi-year record of execution, the company has earned the right to attempt this next turn of the flywheel. Whether it becomes a masterclass in capital structure or a cautionary tale will be decided, as always, not by headlines but by plumbing: cash coverage, FX hygiene, covenant design, and the discipline to keep buying when it’s least comfortable—and to keep cash when it’s most tempting to spend.
