Strategy’s Convertible Bond Prices Surge as Stock Advances Back Toward Record High
MicroStrategy’s (MSTR) aggressive Bitcoin acquisition strategy has significantly impacted its convertible debt. The substantial rise in Bitcoin’s price and MSTR’s stock rebound towards $450 have placed five out of six outstanding bonds “deep in the money,” meaning their conversion price is below the current stock price. Only the 2029 note, with a conversion price of $672.40, remains out of the money.
These bonds, totaling $8.2 billion in notional principal, were issued with exceptionally low average coupons of 0.421%. Maturing between 2028 and 2032, their conversion into common stock is based on MSTR and BTC prices at issuance. MSTR’s stock recovery from a low of $235 three months ago has boosted the bonds’ market value to $13.4 billion, a $5.2 billion premium over their notional value. This premium reflects investor demand in secondary markets, driven by the potential equity conversion.
However, MicroStrategy has recently paused issuing new convertible notes. This pause may be attributed to a more cautious market sentiment observed in options trading. As of July 15th, MSTR’s implied volatility stands at 53.1%, significantly lower than past highs exceeding 200%. This indicates a decreased expectation of significant stock price movement among options traders.
While open interest remains robust at over 2.4 million contracts, both the put-call ratio (0.93) and volume put-call ratio (0.62) suggest neutral sentiment. The low trading volume, at 20% of its 30-day average, further points to reduced speculative interest. This muted options activity contrasts with the earlier market enthusiasm that allowed MicroStrategy to issue convertibles at favorable terms.
Future issuances may require higher yields or lower conversion prices, potentially leading to earlier dilution for existing shareholders. The current market conditions suggest a shift from the highly favorable terms previously enjoyed by MicroStrategy.
