Quantum Computing Inc. (QUBT) Q3 2026 earnings review
Quantum Computing Inc. sales jump on acquisitions, but losses widen
Quantum Computing Inc., a maker of light-based quantum machines and semiconductor chips, lifted sales and turned a gross profit after folding in three acquired businesses, but its overhead and operating losses grew faster. Third-quarter revenue rose to $9.5 million, topping the $9.2 million generated across the entire first half of the year, and gross margin reached 4.5% after three quarters below zero. Chief executive Yuping Huang said the business is shifting toward commercial execution, yet operating expenses reached $29 million and contract backlog slipped to $39 million.
| Revenue | $9.5M +71% from last quarter |
|---|---|
| Gross margin | 4.5% -21.0% last quarter |
| Contract backlog | $39.1M $42.5M last quarter |
| Operating loss | $28.6M $23.0M loss last quarter |
⚖️ Verdict: ⚪ Neutral
The story is unchanged because higher factory utilization from a full quarter of chip packager NHanced was offset by a steep jump in ongoing overhead and a dip in the order book. Excluding one-time deal fees, quarterly operating expenses nearly doubled from last quarter to $28 million by our math, while new order bookings replaced less than two-thirds of the revenue shipped.
The question now is whether the three acquired semiconductor units are winning enough profitable work to cover their combined cost base while QCi builds its quantum machines. Either those factories grow their order book and push gross margins toward 20% to 30%, or shrinking legacy contracts leave QCi funding heavy factory and overhead losses out of its $1.3 billion cash pile. The third-quarter filing's acquisition breakdown and fourth-quarter backlog will show which way the business is moving.
🐂 Bull Case
Gross Margin Turned Positive as Acquired Factories Scaled
Quantum Computing Inc., a maker of light-based computing machines and semiconductor chips, posted a negative gross margin for three straight quarters because its chip factories ran below capacity. In the third quarter, the first full period including chip packager NHanced Semiconductors, gross margin turned positive at 4.5%, up from minus 21.0% in the second quarter.
Cost of revenue, the direct cost of making products and running the foundries, dropped by 25.5 percentage points of sales from last quarter to 95.5%. The New Jersey group said it is focused on "increasing manufacturing utilization and improving operating efficiency as it scales its commercial operations". Higher shipment volume helped cover fixed factory costs, though a 4.5% margin still leaves almost nothing to pay for overhead.
What to watch: fourth-quarter gross margin and factory utilization comments in the quarterly filing. A second consecutive improvement toward double digits would show the chip plants can make money at current order volumes.
Three Acquisitions Built a $9.5 Million Revenue Base
The photonics specialist bought three businesses in the first half of 2026: laser and detector maker Luminar Semiconductors, quantum communications firm NuCrypt, and advanced chip packager NHanced. With all three inside the group for a full quarter, revenue rose 71.1% from the second quarter to $9.5 million, topping the $9.2 million recorded across the entire first half.
Last quarter management stood by external estimates of $20 million to $25 million in full-year sales before counting NHanced, plus $7 million to $16 million from NHanced. Nine-month revenue now sits at $18.7 million. That puts the combined business within reach of the lower end of those annual figures if fourth-quarter shipments hold near the third-quarter level.
What to watch: the acquisition footnote in the third-quarter filing. It will show how much revenue came from NHanced versus Luminar Semiconductors, and whether their sales grew compared with a year ago before QCi bought them.
New Quantum Agreements Reached Medicine and Academia
Chief executive Yuping Huang said "our focus is increasingly shifting from what we can build to what we can put to work for customers". During the quarter the company signed a commercial deal with biotechnology firm INmune Bio to use Dirac, its light-based system for solving complex calculation problems, on clinical data for an experimental Alzheimer's treatment.
It also signed a framework agreement with Hamad Bin Khalifa University in Qatar to provide cloud access to the Dirac-3 machine for research and education. The press release did not state the dollar value of either deal, so they have not yet changed the company's reliance on acquired semiconductor contracts.
What to watch: revenue from QCi's own quantum machines in the quarterly filing's management discussion. Moving that figure past $1 million a quarter would show these commercial agreements pay meaningful sums.
🐻 Bear Case
Operating Expenses Nearly Doubled After Stripping Deal Costs
Absorbing three companies for a full quarter drove a sharp jump in overhead. Total operating expenses rose 32.8% from the second quarter to $29.0 million, or more than three times total revenue. That pushed the operating loss to $28.6 million, widened from $23.0 million last quarter and $10.4 million a year ago.
- General and administrative expense: $15.4 million, or 162% of revenue, up from $11.5 million in Q2
- Research and development expense: $8.3 million, or 88% of revenue, vs $8.4 million in Q2
- Sales and marketing expense: $5.3 million, or 55% of revenue, up from $1.9 million in Q2
- Operating expenses excluding deal fees: $28.0 million, up 93% from $14.5 million in Q2 by our math
Second-quarter expenses included $7.3 million of one-time acquisition fees, whereas the third quarter included only about $1.0 million. Stripping out those deal fees by our math shows that ongoing quarterly operating costs nearly doubled after adding NHanced and expanding staff for "higher personnel expenses and other costs associated with expanded research and development, sales and marketing activities".
What to watch: general and administrative spending in the fourth quarter. If ongoing operating costs stay near $28 million a quarter, the business will burn more than $60 million a year even after counting interest income.
Backlog Shrank as Shipments Outpaced New Orders
Huang listed "growing our commercial business, scaling manufacturing and advancing our quantum roadmap" as his clear priorities. Yet contract backlog, the value of signed orders waiting to be completed, fell from $42.5 million at the end of June to $39.1 million at the end of September.
In the second quarter, backlog jumped only because QCi added NHanced's existing order book. With no new acquisitions in the third quarter, the $3.4 million drop in backlog along with $9.5 million of recognized revenue means the company booked about $6.1 million of net new orders by our math. That equals 64 cents of new work for every dollar shipped.
What to watch: fourth-quarter contract backlog and post-quarter subcontract funding mentioned in the release's legal disclaimers. Another drop below $36 million would show the acquired businesses are working through old contracts faster than they win new ones.
Risks This Quarter Didn't Answer
Because the company released only its earnings announcement and financial tables, several standing risks await the full quarterly filing.
- Underlying sales trend at acquired firms: in Q2 their combined sales fell 42% from a year earlier; the 10-Q pro forma table will show Q3.
- Sales from QCi's own quantum products: totaled $0.45 million in Q2; the 10-Q management discussion will separate acquired revenue from original lines.
- Purchase accounting and goodwill: QCi moved $21.1 million out of goodwill into intangible assets and booked $3.8 million of contingent liabilities; the 10-Q footnotes will detail the NHanced valuation.
- Factory upgrade budget and hardware milestones: the release gave no capital budget for the Fab 2 upgrade and no update on the gate-based quantum prototype.
- Pending shareholder lawsuits: the status of the February 2025 securities class action and derivative suits will appear in the 10-Q legal footnote.
👓 Other Themes
Government and Aerospace Contracts Drive Commercial Sales
QCi stated that third-quarter revenue was "primarily driven by sales of products and services for aerospace, government and industrial applications". That aligns with prior quarters, when government subcontracting accounted for roughly 70% to 80% of business across the acquired units. Relying on defense and aerospace agencies ties quarter-to-quarter bookings to federal budget schedules and contract funding milestones.
💲 Other KPIs
Cash, cash equivalents and short- and long-term investments edged down by $25.6 million from the second quarter to $1.30 billion by our math. That cash pile earned $13.0 million in interest income during the quarter, up from $3.5 million a year ago, covering nearly half of the company's operating loss.
Accounts receivable, money owed by customers for billed work, rose 21.3% from the second quarter to $8.3 million as shipments scaled across the acquired units. Deferred revenue, cash collected upfront for work not yet performed, rose 10.3% from last quarter to $4.2 million.
Weighted average diluted shares rose 35.1% from a year ago following late-2025 stock sales and acquisition share issuances, but grew just 0.3% from the second quarter. With $1.30 billion in cash and investments on hand, QCi did not issue new stock for financing during the quarter.
🔮 Guidance
Unchanged. QCi gives no outlook table in its press releases, but on last quarter's call management stood by external models showing $20 million to $25 million in 2026 sales before counting NHanced, plus $7 million to $16 million from NHanced. With nine-month total sales at $18.7 million, fourth-quarter revenue needs to reach at least $8.3 million to hit the combined $27 million bottom of those two ranges.
❓ Key Questions
Did sales at the acquired businesses stop shrinking?
In the second quarter, combined sales at Luminar Semiconductors, NuCrypt and NHanced fell 42% compared with the prior year before QCi owned them. Investors need the third-quarter comparison table from the filing to see if those acquired businesses have stabilized.
How much revenue came from QCi's own quantum machines?
Sales excluding acquisitions were just $451 thousand in the second quarter. Management signed new commercial and academic partnerships for its Dirac system this quarter, so the standalone quantum revenue figure will show whether those deals bring material cash.
Why did ongoing operating expenses jump to $28 million?
Stripping out acquisition transaction fees, quarterly operating costs rose from $14.5 million in the second quarter to $28.0 million in the third by our math. Management has not explained how much of that increase is permanent payroll versus temporary integration work.
What is the post-quarter subcontract mentioned in the legal notice?
The forward-looking statements paragraph warns of risks around "revenue recognition and funding under the post-quarter subcontract, the negotiation of any definitive contract". Management has not yet disclosed the customer, ceiling value or timeline for this award.
