MicroStrategy Closed a $650 Million Debt Sale to Fund Bitcoin Purchases

MicroStrategy completed a $650 million private offering of convertible senior notes on December 11, 2020 and said it intended to direct the estimated net proceeds into bitcoin under its Treasury Reserve Policy, subject to working-capital needs and other general corporate purposes.

The closing mattered because it moved the business-intelligence company’s bitcoin strategy beyond the use of existing corporate cash. MicroStrategy had now raised unsecured debt from qualified institutional buyers with an explicitly stated plan to use the proceeds for a digital asset. The filing documented the financing; it did not document a completed bitcoin purchase on December 11.

What closed on December 11

MicroStrategy’s Form 8-K said the company sold $650 million aggregate principal amount of 0.750% convertible senior notes due 2025. The total included an additional $100 million option that the initial purchaser, Jefferies LLC, exercised in full on December 9, 2020. After discounts, commissions and estimated expenses, MicroStrategy estimated net proceeds at approximately $634.9 million.

The notes were senior unsecured obligations, meaning the December 11 financing did not identify specific collateral pledged to noteholders. They were sold for resale to qualified institutional buyers under Rule 144A rather than through a registered public offering. Interest was set at 0.750% per year, payable every six months beginning June 15, 2021, and the notes were scheduled to mature on December 15, 2025 unless converted, redeemed or repurchased earlier under their terms.

Applied to the full $650 million principal, the stated coupon implies $4.875 million of annual cash interest, or $2.4375 million per semiannual payment. Those are Coinburn calculations from the principal and coupon, not company-reported financing costs; they exclude issuance expenses and any economic effect from conversion, redemption or repurchase.

The equity option inside the debt

The initial conversion rate was 2.5126 shares of MicroStrategy class A common stock for each $1,000 of principal. The company translated that into an initial conversion price of approximately $397.99 per share, a 37.5% premium to the $289.45 last reported sale price of MicroStrategy shares on Nasdaq on December 8, 2020.

That structure offered investors a fixed coupon plus conditional exposure to MicroStrategy’s equity. Before June 15, 2025, conversion was allowed only during specified periods and after stated conditions; after that date, holders could convert until shortly before maturity. MicroStrategy retained the choice to settle conversions in cash, shares or a combination, subject to the indenture.

The institutional significance was therefore broader than the headline amount. Bitcoin exposure was being connected to a conventional corporate-security channel available to eligible bond buyers. Yet buyers held claims on MicroStrategy, not direct claims on bitcoin. Their outcomes depended on the note terms, the company’s credit and stock, and management’s later deployment of the proceeds.

What was not established on the event date

The December 11 filing used forward-looking language: MicroStrategy intended to invest the net proceeds in bitcoin, pending identification of business cash needs. It did not state how many bitcoins had been bought, identify execution venues or custodial addresses, or establish a market impact. No event-day bitcoin price is used here because cryptocurrency trades continuously across venues and the financing record does not provide a purchase-window benchmark.

Contemporaneous specialist coverage confirmed that the completed offering had expanded from the company’s earlier proposed amount and emphasized the intended bitcoin use. That reporting did not alter the narrower legal record: on December 11, the verified event was the debt closing and stated allocation plan.

Later context: December 21, 2020

MicroStrategy announced on December 21, 2020 that it had acquired approximately 29,646 bitcoins for approximately $650 million in cash. That later purchase is not evidence that bitcoin had already been acquired on December 11; it is the subsequent corporate milestone that resolved the principal event-day uncertainty.
