Frequently asked FLY fail to deliver questions
- What is the latest FLY fail-to-deliver count?
- As of Apr 30, 2026, Firefly Aerospace Inc. (FLY) fail-to-deliver quantity is 37.2K shares, with a 30-day average of 100.6K shares. The SEC publishes FTD data twice monthly: first-half data at month-end, second-half around the 15th of the following month.
- What is the FTD aggregate net balance?
- FTD figures represent the aggregate net balance in NSCC's Continuous Net Settlement (CNS) system, not the gross failed-share count. The published numbers run 2-6 weeks stale relative to the underlying settlement date.
- How do FLY FTDs affect options pricing?
- Persistent FTDs flag hard-to-borrow conditions that distort put-call parity: in HTB names, synthetic long stock (long call + short put at the same strike) trades below the frictionless-parity price by approximately the borrow rebate. The discount equals the lending revenue forgone by holding the synthetic instead of actual shares. Reg SHO threshold-list inclusion follows from sustained FTD persistence.
