4 things going right for Firefly Aerospace that this headline doesn't cover.

Firefly Aerospace’s engine deal leans into the hardware plus software Narrative, but cash conversion is still the missing link

For Firefly Aerospace investors, this Miranda and Vira agreement lines up neatly with the existing Narrative that the business is building multi program exposure across launch, lunar and software. The US$800 million package of cash and equity from AST SpaceMobile, layered on top of NASA CLPS work and SciTec’s AI software, speaks directly to the multi mission, multi orbit and AI enabled sensing catalysts already flagged for the stock. It also connects with the recent jump in sales to US$110.68 million in the third quarter of 2026 and the firm’s push to monetise its hardware platforms across more customers.

See how these catalysts shape Firefly Aerospace's path to a $36.64 fair value.

The unresolved issue is still execution on profitability. The key tell will be whether future quarters show Firefly’s net loss, which was US$94.2 million in the latest quarter, narrowing in step with engine licensing and services revenue flowing from AST SpaceMobile and other wins like CLPS 2 task orders.
