A debt-financed bitcoin plan
MicroStrategy priced $550 million of 0.750% convertible senior notes due 2025 on December 9, 2020, and said it intended to direct the net proceeds into bitcoin under its treasury reserve policy, subject to working-capital and other general corporate needs. The private offering targeted qualified institutional buyers under Rule 144A and was expected to close on December 11, 2020, if customary conditions were met.
The pricing mattered because MicroStrategy was no longer proposing to use only cash already sitting on its balance sheet. It was arranging unsecured senior debt whose proceeds could substantially expand an existing bitcoin position. That linked the company's credit, equity and treasury decisions to a volatile digital asset in a more direct way than its earlier cash purchases.
The December 9 terms were specific but not yet a completed financing or a bitcoin purchase. MicroStrategy estimated net proceeds of approximately $537.2 million after discounts, commissions and estimated expenses. It also gave the initial purchasers a 13-day option for another $100 million of principal; full exercise would have raised estimated net proceeds to approximately $634.9 million. Those figures were company estimates in an offering announcement, not cash already received or bitcoin already acquired.
What investors were being offered
The notes were to pay interest twice a year at an annual rate of 0.750% and mature on December 15, 2025 unless converted, redeemed or repurchased earlier under their terms. The initial conversion rate was 2.5126 MicroStrategy Class A shares per $1,000 principal amount, equivalent to an initial conversion price of approximately $397.99 per share.
MicroStrategy calculated that conversion price as a 37.5% premium to the $289.45 last reported Nasdaq sale price of its Class A stock on December 8, 2020. That comparison describes the equity conversion terms; it is not a bitcoin return forecast. Conversion could be settled in cash, shares or a combination at the company's election, and before June 15, 2025 it was limited to specified events and periods.
For institutional buyers, the structure combined a senior unsecured claim and a small coupon with conditional exposure to MicroStrategy's equity. For MicroStrategy, it created interest and repayment obligations while potentially supplying far more purchasing capacity than another ordinary allocation of operating cash. The central uncertainty on December 9 was therefore two-sided: whether the offering would close as planned and how much of the resulting net cash would ultimately be deployed into bitcoin.
Scale against the existing treasury
A December 4, 2020 SEC filing provides the cleanest contemporaneous baseline. MicroStrategy reported holding approximately 40,824 bitcoin acquired for an aggregate $475 million, inclusive of fees and expenses. The same filing said its latest purchase was approximately 2,574 bitcoin for $50 million in cash, at an average price of approximately $19,427 per bitcoin.
Comparing the December 9 estimated base net proceeds of $537.2 million with the $475 million historical acquisition cost reported five days earlier shows the potential scale: the financing, if completed and substantially used as stated, could fund bitcoin purchases whose dollar amount exceeded the company's existing aggregate bitcoin cost. That is a comparison of disclosed dollar amounts, not proof of a specific number of future coins. Bitcoin's execution price, fees, timing and any cash retained for corporate needs were unknown on December 9.
The event-day limit
The verified development on December 9 was the pricing of a private convertible-note offering and a stated intended use of proceeds. It was not evidence that $550 million had settled, that the additional $100 million option had been exercised, or that any new bitcoin had been purchased. Those distinctions preserve the event-day record: a consequential financing commitment had taken shape, but its closing, final proceeds and asset deployment still required later primary records.
