Rocket Lab (RKLB) Q3 2026 earnings review
Rocket Lab's backlog jumps 52%, but Neutron slips into 2027
Rocket Lab booked more than $1 billion in new orders and removed its biggest financing risk, even as its new medium-lift rocket slipped again. The rocket and satellite maker grew revenue 73% from a year ago, beat its own gross margin plan, and generated positive operating cash flow as customer prepayments poured in. Chief executive Sir Peter Beck highlighted 16 contracted missions for the upcoming Neutron rocket, with base prices rising to $70 million, while the fourth-quarter outlook calls for both revenue and gross margins to expand.
| Revenue | $267.8M +72.7% from a year ago |
|---|---|
| Total backlog | $3.57B +52% from last quarter |
| Gross margin, excluding one-offs | 38.4% 35–37% outlook |
| Q4 revenue outlook | $270–290M middle of the range: +56% from a year ago |
⚖️ Verdict: 🟢 Bullish
The story got better because Rocket Lab eliminated the $3.6 billion bridge-loan risk on its pending Iridium purchase and proved it can raise Neutron prices before the rocket flies. Selling $2.38 billion of stock in the quarter funded the cash portion of the Iridium deal, and lenders agreed to keep Iridium's existing credit facility in place. The bad news: Neutron's debut slipped from late 2026 to no earlier than 2027, pushing out operating profitability, and the stock sales lifted the fourth-quarter share count by 19% from a year ago by our math.
The question now is whether Neutron can fly early in 2027 and unlock the $515 million of new constellation contracts without another costly delay. One side sees the 16-launch backlog and $70 million price tag as proof of scarce launch capacity; the other sees a fifth schedule slip and rising research spending. Delivery and testing of the full flight vehicle at Launch Complex 3 over the next two quarters will settle it.
🐂 Bull Case
Backlog Jumped 52% as Rocket Prices Rose
Rocket Lab's backlog — contracted orders not yet filled — jumped by $1.21 billion in a single quarter to $3.57 billion. Chief executive Sir Peter Beck said the company signed nearly $1 billion in new launch contracts and $470 million in Space Systems orders, its satellite and parts unit.
- Total backlog: $3.57 billion, up 52% from last quarter and up 225% from a year ago by our math
- Total launches on contract: 117 across Electron (small orbital rocket), HASTE (suborbital defense rocket) and Neutron, up from 90 last quarter
- Neutron backlog: 16 missions after adding over $515 million in third-quarter contracts from satellite constellation operators
- Neutron base price: $70 million on several new missions, up 33% by our math from its earlier $50–55 million target
The company said it is "lifting the base launch price to $70 million for several of these missions as industry launch capacity tightens". Raising prices by a third before the rocket has flown shows that satellite operators have few alternatives for medium-lift launches.
What to watch: the percentage of backlog expected to turn into revenue within 12 months in the quarterly filing. A figure near last quarter's 45.5% would point to more than $1.6 billion of revenue over the next year.
Stock Sales Removed the Iridium Financing Risk
Last quarter, Rocket Lab agreed to buy satellite operator Iridium Communications, creating a major financing risk because the deal relied on a $3.6 billion short-term bridge loan and a potential refinancing of Iridium's debt. This quarter, the company eliminated both borrowing risks before closing.
Rocket Lab "Fully funded Rocket Lab’s pending acquisition of Iridium Communications through a completed ATM equity offering", raising $2.38 billion in the third quarter by our math from selling shares on the open market. It also "received approval by Iridium lenders to maintain Iridium’s credit facility post-transaction" and won approval from Iridium shareholders.
Replacing short-term bridge debt with cash on the balance sheet removes the risk of forced refinancing in a tight credit market, while keeping Iridium's existing loans avoids higher interest rates.
What to watch: regulatory approvals from telecom and competition authorities in the first half of 2027. Clearing those hurdles will allow the purchase to close as planned in mid-2027.
Gross Margins Beat the Plan and Point Higher
Rocket Lab builds complete satellites, which carry lower profit margins, and individual spacecraft parts, which carry higher margins. Management had warned that a shift toward satellite assembly and the addition of laser-communications maker Mynaric would push GAAP gross margin down to 29–31% in the third quarter.
Instead, GAAP gross margin reached 33.6%, and gross margin excluding one-offs hit 38.4% against a 35–37% plan. Product gross margin rose 2.6 percentage points from a year ago by our math to 32.6%, while service gross margin fell 14.7 points to 36.5%. For the fourth quarter, the company plans for GAAP gross margin to expand to 34–36%.
What to watch: fourth-quarter gross margin against the 34–36% GAAP plan. Hitting that range will show that higher launch pricing and parts sales are offsetting lower-margin government satellite assembly.
Customer Prepayments Pushed Operating Cash Into Profit
Heavy spending on rocket development and satellite inventory had pushed Rocket Lab's free cash flow — operating cash minus factory spending — to a record $110.1 million outflow last quarter. In the third quarter, GAAP operating cash flow turned positive at $7.2 million.
By our math, after subtracting $31.1 million of factory and equipment purchases, free cash flow outflow narrowed to $23.9 million, or 8.9% of revenue. Customer prepayments on new contracts drove the turnaround, lifting contract liabilities by $72.4 million during the quarter to $423.6 million.
What to watch: fourth-quarter operating cash flow alongside Neutron testing expenses. Remaining near breakeven before Neutron flies will show that upfront payments on the $3.57 billion backlog can fund ongoing rocket development.
🐻 Bear Case
Neutron's First Flight Slipped Into 2027
“Our end-to-end space strategy is delivering exactly as designed,” Beck said. Yet the centerpiece of that strategy is Neutron, Rocket Lab's reusable medium-lift rocket, which management previously aimed to launch in late 2026 after a tank burst in testing earlier this year.
The company pushed the debut out again, stating: "With first launch now targeted for no earlier than 2027". Meanwhile, GAAP research and development spending rose 39% from a year ago to $98.4 million (though falling 8.9 percentage points as a share of revenue to 36.7% by our math), pushing operating expenses excluding one-offs to $130.2 million, above the $121–127 million plan.
This delay matters because management has tied positive Adjusted EBITDA — profit before interest, taxes, depreciation and one-offs — to the quarter after Neutron's first flight. Consequently, the fourth-quarter outlook calls for another Adjusted EBITDA loss of $14–20 million.
What to watch: completion of first-flight hardware delivery and testing at Launch Complex 3 in Virginia. Any further test failures would push the first launch deeper into 2027 and delay operating profitability.
Paying for Iridium With Stock Diluted Shareholders
Eliminating the Iridium bridge loan came at a direct cost to existing shareholders' ownership slice. Rocket Lab has now raised $3.91 billion in gross proceeds from at-the-market stock offerings over the first nine months of 2026, including $2.38 billion in the third quarter alone by our math.
Those stock sales, along with convertible note conversions earlier in the year, lifted basic weighted-average shares by 23.4% from a year ago to 652.3 million, exceeding the 641 million plan. Management's fourth-quarter outlook projects 681 million shares, up 19.0% from a year earlier by our math, even before Rocket Lab issues additional stock to Iridium shareholders at closing.
What to watch: the final number of shares issued to Iridium stockholders when the purchase closes. A larger share count means future space profits must be spread across far more shares.
Risks this quarter didn't answer
Four standing concerns from prior quarters cannot be checked from the earnings release and await the quarterly Form 10-Q filing.
- Underlying sales growth: the release does not separate sales from businesses owned a year ago from recent acquisitions Mynaric and Motiv; the filing's pro forma table will show whether underlying growth slowed from last quarter's 37%.
- Mynaric profit drag: the release gives no standalone revenue or operating loss for the acquired laser-communications unit; the filing's footnote will show if its losses narrowed.
- Government concentration: the split of revenue and backlog between commercial and government customers is not in the release; the filing's backlog footnote will update it.
- Late satellite-bus deliveries: potential financial penalties on the delayed 17-spacecraft MDA contract were not mentioned; the filing's commitments footnote will show if exposure changed.

One-Off Charges Widened the Reported Net Loss
Rocket Lab's GAAP net loss widened to $79.7 million from $18.3 million a year ago because of three non-operating items. Selling, general and administrative expenses included $21.3 million of Iridium transaction costs, other expense included a $27.3 million loss on extinguishing convertible debt, and the year-ago quarter included a $41.1 million tax benefit. Excluding those items, the net loss narrowed from $54.2 million to $31.1 million by our math.
💲 Other KPIs
Contract liabilities — cash customers have paid upfront for launches and satellites not yet delivered — rose 20.6% from last quarter and 116.7% from the end of 2025 by our math. The $144.5 million nine-month cash inflow from these prepayments funded inventory build and pushed third-quarter operating cash flow into positive territory.
By our math, purchases of property, equipment and software rose to $31.1 million in the third quarter from $26.0 million in the second quarter and $27.1 million in the first. Even with the sequential step-up for Neutron launch pad and satellite factory equipment, capital spending fell to 11.6% of revenue from 29.6% a year ago.
Cash, marketable securities and restricted cash nearly doubled from $2.40 billion last quarter to $4.71 billion by our math, while convertible debt fell from $13.1 million to $1.3 million. The cash pile came from selling stock to fund the pending Iridium purchase and generated $28.6 million in third-quarter interest income.
🔮 Guidance
New. The plan calls for revenue to rise 4.5% from the third quarter at the middle of the range ($280 million) and 55.9% from a year ago by our math. That marks a slower year-on-year pace than the third quarter's 72.7% as last year's GEOST acquisition enters the comparison base. Rocket Lab has beaten its revenue midpoint for four straight quarters by an average of 2.9%.
New. At the 35% middle of the range, GAAP gross margin expands by 1.4 percentage points from the third quarter's 33.6% as launch cadence and higher-margin spacecraft parts mix improve.
New. The 40% middle of the range steps up 1.6 percentage points from the third quarter's 38.4%, matching management's earlier statement that margins would recover after the third quarter.
New. At the $165 million middle of the range, GAAP operating expenses fall 2.5% from the third quarter's $169.3 million because third-quarter acquisition transaction costs of $21.3 million do not repeat at the same level.
New. Excluding stock-based compensation of $17–19 million and acquisition items, operating expenses rise 6.8% from the third quarter at the $139 million middle of the range as Neutron testing continues.
New. The planned loss narrows by $1.0 million at the middle of the range ($17 million loss) from the third quarter's $18.0 million loss, as higher gross profit slightly outpaces Neutron research and development.
New. Net interest income jumps from $28.3 million in the third quarter to $45 million, reflecting a full quarter of interest on the $4.71 billion cash balance.
New. The share count rises 4.4% from the third quarter's 652.3 million (and 19.0% from a year ago by our math) as shares sold during the third quarter count for a full period.
❓ Key Questions
What was sales growth from businesses owned a year ago?
Reported revenue grew 72.7%, but the comparison includes recently acquired Mynaric and Motiv. Last quarter, underlying sales growth in the filing's pro forma table was 37% against 62% reported.
What was the revenue split between Launch and Space Systems?
The press release reports product and service revenue but omits the segment breakdown between Launch and Space Systems, which is needed to check launch pricing against satellite assembly volume.
When in 2027 will Neutron fly, and what remains unbuilt?
Target first flight moved from late 2026 to no earlier than 2027. Investors need to know whether Stage 1 tank qualification is complete and which quarter in 2027 management now targets.
How much did Mynaric lose in the third quarter?
In the second quarter, Mynaric lost $13.2 million on $13.2 million of revenue. Management has not disclosed whether its margins improved or contributed to the third-quarter gross margin beat.
