The amount of revenue recognized in a period may vary with respect to the allocation of arrangement consideration to performance obligations with different revenue recognition patterns and changes to existing contract terms. For certain contracts, revenue is recognized over time based on the efforts incurred to date relative to the total expected effort, primarily based on a cost-to-cost input measure.
Contracts with customers are evaluated at the time of execution and may vary in terms. The amount of revenue recognized in a period may vary with respect to the allocation of arrangement consideration to performance obligations with different revenue recognition patterns and changes to existing contract terms.
Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth in the section titled “Risk Factors.” Other than operating expenses and our continued investment in our quantum computers, cash requirements for fiscal year 2024 are expected to consist primarily of capital expenditures for facilities.
Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth in the section titled “Risk Factors.” Our material contractual commitments as of December 31, 2024, primarily relate to operating lease commitments.
As a result, we expect that our general and administrative expenses will increase in absolute dollars but may fluctuate as a percentage of total revenue over time. Depreciation and amortization Depreciation and amortization expense results from depreciation and amortization of our property and equipment, including our quantum computing systems, and intangible assets that are recognized over their estimated lives.

To date, we have estimated the standalone selling price based on other contracts for similar products and services adjusted for differing terms than the contract being evaluated, as well as internal pricing guidelines and market factors. In addition, we take into consideration the estimated costs to be incurred to satisfy the performance obligation plus an appropriate profit margin.
Certain products and services have limited or no history of being sold on a standalone basis, requiring us to estimate the standalone selling price. To date, we have estimated the standalone selling price based on other contracts for similar products and services adjusted for differing terms than the contract being evaluated, as well as internal pricing guidelines and market factors.
In limited situations, for certain contracts executed in prior years, when the standalone selling price was not known, due to it being either highly variable or uncertain, we allocated the transaction price using the residual approach. Contracts with customers are evaluated at the time of execution and may vary in terms.

We supplement our QCaaS offering with professional services focused on assisting our customers in applying quantum computing to their businesses. We also expect to sell full quantum computing systems to customers, either over the cloud or for local access. We are still in the early stages of commercial growth. Since our inception we have incurred significant operating losses.
We supplement our offerings with professional services focused on assisting our customers in applying quantum computing and networking to their businesses. We also expect to sell full quantum computing systems to customers, either over the cloud or for local access. We also offer quantum networking products which offer customers secure communication networks and enable networked quantum computing.
Such contracts may also include access to our QCaaS. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when or as the performance obligation is satisfied. When there are multiple performance obligations in a contract, we allocate the transaction price to each performance obligation based on its standalone selling price when available.
Certain of our contracts contain multiple performance obligations, most commonly in contracts for the sale of specialized quantum computing hardware together with related maintenance and support. Such contracts may also include access to our QCaaS. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when or as the performance obligation is satisfied.
We determine standalone selling price based on the observable price of a product or service when we sell the products or services separately in similar circumstances and to similar customers.

The increase was primarily due to an increase of $8.7 million of payroll-related expenses, including an increase in stock-based compensation of $5.5 million, as a result of increased headcount, and increased costs to promote our services and other marketing initiatives of approximately $1.2 million.
The increase was primarily driven by an increase of $10.0 million of payroll-related expenses, including an increase in stock-based compensation of $7.0 million, as a result of increased headcount and new equity grants.
Our ability to generate revenue sufficient to achieve profitability will depend heavily on the successful development and further commercialization of our quantum computing systems. Our net losses were $157.8 million and $48.5 million for the years ended December 31, 2023 and 2022, respectively. As of December 31, 2023, we had an accumulated deficit of $352.1 million.
Our net losses were $331.6 million, $157.8 million and $48.5 million, for the years ended December 31, 2024, 2023 and 2022, respectively. As of December 31, 2024, we had an accumulated deficit of $683.7 million.
For performance obligations related to providing QCaaS access, fixed fees are recognized on a straight-line basis over the access period. We are currently focused on marketing our QCaaS and consulting services and have entered into, and are continuing to enter into, new contracts with customers.
For performance obligations related to providing QCaaS access, fixed fees are recognized on a straight-line basis over the access period. Variable usage fees are recognized in the period they occur.
We have determined that our QCaaS contracts represent a combined, stand-ready performance obligation to provide access to our quantum computing systems together with related maintenance and support. The transaction price generally consists of a fixed fee for a minimum volume of usage to be made available over a defined period of access.
Estimates related to standalone selling price have not had a material impact on revenue recognized in recent periods. We have determined that our QCaaS contracts represent a combined, stand-ready performance obligation to provide access to our quantum computing systems together with related maintenance and support.
We have also engaged with certain prospects who are interested in purchasing entire quantum computers, either over the cloud or for local access. 54 Operating Costs and Expenses Cost of revenue Cost of revenue primarily consists of expenses related to delivering our services, including personnel-related expenses, allocated facility and other costs for customer facing functions, and costs associated with maintaining our in-service quantum computing systems to ensure proper calibration as well as costs incurred for maintaining the cloud on which the QCaaS resides.
Factors considered in these estimates include our historical performance, the availability, productivity and cost of labor, the nature and complexity of work to be performed, the effect of change orders, availability and cost of materials and the effect of any delays in performance. 57 Operating Costs and Expenses Cost of revenue Cost of revenue primarily consists of expenses related to construction of specialized quantum computing hardware and delivery of our services, including personnel-related expenses, hardware costs, allocated overhead costs for customer facing functions, and costs associated with maintaining our in-service quantum computing systems to ensure proper calibration as well as costs incurred for maintaining the cloud on which the QCaaS resides.
However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all. High interest and inflation rates present a recent challenge impacting the U.S. economy and could make it more difficult for us to obtain traditional financing on acceptable terms, if at all, in the future.
However, we may be unable to raise additional funds or enter into such other arrangements when needed on favorable terms or at all.
Our material cash requirements as of December 31, 2023, include operating lease commitments, including the lease of our headquarters in College Park, Maryland and our manufacturing, research and development and general office space in Bothell, Washington.
