Firefly Aerospace Stock (FLY) Stalls as $106 Million Cash Burn Tests Record Revenue

CEDAR PARK, Texas, Aug 11, 2026, 16:52 EDT

  • Record quarterly revenue reached $117.7 million, up 659%.
  • Free cash flow was negative $106.3 million.
  • The $420 million to $450 million annual revenue guide was unchanged.

Firefly Aerospace Inc. shares slipped 0.6% to $26.20 in preliminary extended trading on Tuesday. Record quarterly sales beat expectations, but cash burn nearly matched revenue. The regular session had ended 2.3% higher at $26.36.

Stock chart for NASDAQ:FLY

The muted reaction puts cash conversion at the centre of the investment case. Revenue rose fast, yet free cash flow worsened to negative $106.3 million. Adjusted EBITDA also remained deeply negative.

That gap matters at Firefly’s current valuation. The company is valued for sustained execution across launch, spacecraft and lunar programmes. One strong quarter alone does not settle that test.

Q2 scorecardQ2 2026Q2 2025Change / comparison
Revenue$117.7m$15.5m+659%; above $89.6m consensus

GAAP net loss$92.3m$63.8mLoss widened 44.7%
Gross margin20.3%25.7%Down 5.4 percentage points

Revenue exceeded the pre-release consensus by about 31%. The adjusted loss per share was also narrower than expected. Those estimates came from third-party analyst compilations and remain subject to revision.

Profit measures gave a more mixed signal. Gross profit reached $23.9 million, but operating expenses were $119.1 million. The operating loss was therefore $95.2 million.

Cash conversionQ2 2026Q2 2025
Operating cash used$81.6m$25.9m
Capital spending and internal software$24.7m$11.4m
Free cash flow-$106.3m-$37.3m
Free cash flow / revenue-90.3%-239.7%

The ratio improved sharply because revenue scaled. Absolute cash use still nearly tripled. Firefly held $635.3 million in cash and short-term investments at quarter-end.

The balance was strengthened by $181.6 million of net public-offering proceeds. Net cash was about $608.3 million after reported notes payable. That provides runway, though spending remains substantial.

Outlook and valuation testValue
First-half 2026 revenue$198.6m
Full-year revenue guidance$420m-$450m
Second-half revenue needed at midpoint$236.4m
Cash plus short-term investments$635.3m
Estimated enterprise value / guidance midpointAbout 8.6 times

The guidance midpoint requires $236.4 million of second-half revenue. That is almost exactly two more quarters at the latest run rate. The hurdle looks attainable, but leaves little room for programme delays.

Chief Executive Jason Kim said, “Breaking the $100 million mark with another quarterly revenue record demonstrates Firefly’s amplified growth.” Firefly reported more than six contract wins during the quarter. Company release

Those awards included a $144 million NASA lunar contract and a $94 million U.S. Space Force deal. Firefly also extended a Lockheed Martin Corp. launch agreement to as many as 25 missions through 2031.

ConsensusModerate Buy
Average target$40.64
Target range$25-$60

The average target implies about 54% upside from Tuesday’s close. However, these targets pre-date the latest results. Estimate changes now matter more than the old average.

The stock gained 13.0% from its Aug. 4 close through Tuesday. Next week’s focus is whether analysts lift revenue estimates without widening expected losses.

Risks: Launch failures, contract timing and cost overruns can shift revenue between quarters. The preliminary after-hours price also reflects thinner trading than the regular session.

Wall Street closed lower before the release. The S&P 500 lost 0.35%, while the Nasdaq fell 0.74%. Firefly’s regular-session gain therefore outpaced the broad market.

Further analysis

What caused Firefly Aerospace shares to stagnate following record-breaking revenue?
Revenue hit an all-time high of $117.7 million, surpassing the pre-release consensus by roughly 31%. Despite this, free cash flow stood at a negative $106.3 million. The subdued initial response indicates that investors continue to look for evidence that strong sales expansion will lower overall cash outflow.
Is Firefly Aerospace positioned to achieve its revenue target for 2026?
The midpoint target is still within range. Firefly reported $198.6 million in revenue for the first half and requires around $236.4 million during the remainder of the year. This is nearly equal to two more quarters at the current run rate, but programme delays could defer revenue.
What is the length of Firefly Aerospace's financial runway?
As of June 30, Firefly's cash and short-term investments totaled $635.3 million. Notes payable stood at roughly $27.0 million. The available balance enables further investment; however, a quarterly free-cash-flow loss of $106.3 million highlights the significance of conversion.
What are the next key developments for Firefly Aerospace investors to monitor?
Monitor changes in estimates, contract schedules and reported losses. The consensus analyst target price of $40.64 suggests significant potential gains, though this figure was set before the most recent filing. The main question is whether revenue growth will continue without a corresponding increase in cash outflows.
