Archer recorded $5.0 million of revenue in the six months ended June 30. That is the easy part of the filing.
The harder part is that operating cash outflow rose to $305.5 million from $198.0 million a year earlier, even as the company moved from no revenue to $5.0 million. Operating loss widened to $279.2 million from $176.1 million. The business has started collecting revenue, but it is still spending roughly $61 in operating cash for every dollar it records.
Archer says the bigger loss came from a larger operating machine: research and development expense rose 52% to $186.0 million, while personnel, outside services, infrastructure, facilities, and litigation costs also increased. The company’s explanation is unusually specific.
"The increase was primarily due to an increase of $34.8 million in stock-based compensation expense, an increase of $11.7 million in personnel-related expenses, driven by an increase in our workforce, an increase of $22.1 million in professional services and IT infrastructure expenses, an increase of $8.4 million in facilities, travel, and other operating costs and an increase of $6.0 million for litigation settlement-related expense."
10-Q 2026-08-10; loss quality
Stock-based compensation is a non-cash expense, so it did not itself drain the bank account. It did increase the cost recorded in the income statement, and diluted shares rose 35%, to 781.7 million from 579.2 million. The cash-consuming pieces were the larger workforce, outside services, infrastructure, and the company’s continued research effort.
That research effort is also the company’s stated reason for the cash burn. Archer’s cash balance fell to $852.7 million from $1.7 billion, while capital spending rose 141% to $69.7 million. The balance sheet still has cash, but the latest six-month comparison shows the development program using it faster.
"Net cash used in operating activities during the six months ended June 30, 2026 was $305.5 million, resulting from a net loss of $480.9 million, reflecting our continued investment in our research and development activities."

The quote refers to a net loss figure that includes non-cash adjustments. That distinction matters: the cash-flow line is the cleaner measure of money leaving the business, and it rose by more than half. Archer also disclosed a non-cash change in the fair value of warrant liabilities, another accounting mark rather than a cash payment.
The market snapshot adds a separate wrinkle, not an explanation. Archer shares closed at $6.26 on August 10, up 12.2% that day, even though the six-month filing shows deeper operating losses, heavier cash use, and more diluted shares. The stock’s recent move and the company’s cash arithmetic are describing different surfaces of the same still-developing business.
Archer has revenue now, but it is still spending far more cash than it records in sales.
