Firefly (FLY) Q4 2025 earnings review
Transformative Revenue Growth Masks Expanding Cash Burn
Firefly capped off a historic 2025 with accelerating Q4 revenue of $57.7M, driving full-year sales up 163% to $159.9M. The acquisition of SciTec is successfully shifting the company from a pure-play hardware launch provider to a vertically integrated space and defense prime. However, the core operations remain highly capital-intensive. Free cash flow burn worsened in Q4, driving the full-year outflow to $237.7M. While the headline Net Loss of $41.1M in Q4 looks like a massive improvement, it is an optical illusion created by a $37.1M tax benefit. Operating losses actually expanded. With a fortress balance sheet of $793M post-IPO, Firefly has the runway to execute, and FY26 guidance calls for a staggering near-tripling of revenue to $435M (midpoint).
🐂 Bull Case
The SciTec acquisition immediately validates the transition to an end-to-end provider. Winning an 8-figure space control software contract and operating the Space Force's FORGE missile warning ground systems opens up lucrative, sticky, software-driven government revenue.
Alpha's successful return-to-flight in March 2026 and the historic commercial landing of Blue Ghost Mission 1 on the Moon prove the engineering chops. Securing Mission 4 for the lunar south pole cements Firefly as a trusted NASA CLPS partner.
🐻 Bear Case
Despite 163% YoY revenue growth in FY25, loss from operations worsened from -$209.5M to -$260.7M. SG&A expenses nearly doubled, indicating scaling the business is currently destroying operating margins.
Because hardware revenue is heavily tied to point-in-time launch events and milestone percentage-of-completion, sales swung wildly in 2025: $55.9M (Q1) to $15.5M (Q2) to $30.8M (Q3) to $57.7M (Q4). This creates massive quarter-to-quarter margin volatility.
⚖️ Verdict: ⚪
Neutral. The top-line momentum and FY26 guidance are undeniably accelerating. But until the SciTec software margins begin to visibly offset the brutal capital intensity of the launch hardware, the cash burn remains a structural headwind.
Key Themes
SciTec Integration Unleashes Software Revenue
SciTec is the real star of the Q4 narrative. Firefly is aggressively moving beyond the low-margin launch business into the high-margin data and defense software space. Securing a new eight-figure space control software contract and expanding the FORGE Enterprise OPIR Services contract from $263M to $372M proves that the integration is generating immediate, accretive government wins.
Tax Benefit Masks Worsening Operating Losses
A major red flag is buried in the Q4 income statement. The headline Net Loss optically improved by 51% YoY (from -$84.1M to -$41.1M). This completely contradicts the operational reality. Q4 Operating Loss actually expanded to -$85.6M (from -$77.2M). The entire 'improvement' was driven by a $37.1M one-time income tax benefit related to the SciTec acquisition. Investors should strip this out to see the true cost of operations.
Blue Ghost Lunar Franchise is Legitimized
The successful landing of Blue Ghost Mission 1 and completion of 14 days of lunar surface operations is a massive technical de-risking event. More importantly, it directly drives future backlog. The company secured the Blue Ghost Mission 4 contract to the Moon's south pole, giving Firefly a sustainable, multi-year cadence of high-value NASA contracts.
Cash Burn Trajectory Continues to Worsen
Free cash flow is decelerating alarmingly on a quarterly basis. FCF went from -$37.3M in 25Q2, to -$62.0M in 25Q3, to -$79.3M in 25Q4. While the company's $793M cash balance post-IPO provides a thick cushion, burning roughly $80M a quarter limits their margin of error for the upcoming Eclipse rocket development and Alpha Block II rollout.
Alpha Block II & Eclipse Progress
Hardware iterations are advancing. Firefly passed acceptance testing for the Alpha Flight 8 second stage liquid oxygen tank, preparing for the debut of the upgraded Alpha Block II. Simultaneously, they completed the critical qualification of the interstage connecting Eclipse's first and second stages, keeping the 16-ton medium-lift vehicle on track for its targeted 2026 debut.
Macro Tailwinds in National Security Space
Management continues to successfully map the product portfolio directly against major Space Force budgets. Being onboarded to the Missile Defense Agency's $151B SHIELD IDIQ contract, combined with the Elytra orbiter completing its CDR for the Defense Innovation Unit's space domain awareness mission, puts Firefly squarely in the middle of the Pentagon's push for tactically responsive space.
Other KPIs
Reversing positively. For the full year, gross profit flipped to $30.7M (19.2% margin) compared to a loss of -$11.4M in FY24. This proves that the unit economics of the hardware and software mix can be profitable, even if heavily overshadowed by current R&D and SG&A overhead.
Stable and robust. Cash and cash equivalents ended the year at roughly $793M, up drastically from $123.4M in FY24 due to the IPO. Debt levels are manageable, with $288.5M in total notes payable, primarily related to the SciTec acquisition funding.
Stable but severely negative. Adjusted EBITDA loss slightly widened from -$190.6M in 2024. The adjustments correctly strip out the $37.1M tax benefit, $50.3M in warrant liability changes, and $30.4M in debt extinguishment losses to reveal the persistent underlying burn rate.
Guidance
Accelerating dramatically. The midpoint of $435M implies an incredible 172% YoY growth rate. This signals immense confidence in the SciTec backlog converting to revenue, alongside an aggressive schedule for Alpha launches and Blue Ghost milestone completions. If achieved, this scale will fundamentally alter the company's margin profile.
Key Questions
Revenue Mix in FY26 Guidance
With FY26 revenue guided to more than double to $435M, what is the exact split expected between legacy Firefly hardware (launches/spacecraft) versus SciTec software and ground systems?
Path to Free Cash Flow Breakeven
Q4 FCF burn accelerated to nearly $80M. Assuming the company hits the $435M revenue midpoint next year, at what revenue threshold do you expect the business to turn cash flow positive?
Eclipse Development Costs
With the Eclipse medium-lift vehicle targeting a 2026 debut, how much of the projected 2026 R&D and CapEx budget is specifically ring-fenced for completing Eclipse hardware integration?
