In arrangements with the cloud service providers, the cloud service provider is considered the customer and we do not have any contractual relationships with the cloud service providers’ end users. 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.
In arrangements with the cloud service providers, the cloud service provider is considered the customer and we do not have any contractual relationships with the cloud service providers’ end users. 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.
We may, in the future, enter into arrangements to acquire or invest in complementary businesses, services, and technologies, which may require us to seek additional equity or debt financing. Upon the closing of the Business Combination, we received approximately $636.0 million of gross proceeds.
We may, in the future, enter into arrangements to acquire or invest in complementary businesses, services, and technologies, which may require us to seek additional equity or debt financing. Our primary uses of cash and investments are to fund our operations as we continue to grow our business.
Certain of our contracts contain multiple performance obligations, most commonly in contracts for specialized quantum computing systems 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.
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.
Revenue is recognized on performance obligations satisfied over time based on the efforts incurred to date relative to the total expected effort. 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. 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.
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. 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.
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. Certain products and services have limited or no history of being sold on a standalone basis, requiring us to estimate the standalone selling price.
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. When the standalone selling price is not known, due to it being either highly variable or uncertain, we allocate the transaction price using the residual approach.

We have determined that contracts that contain consulting 60 services related to co-developing quantum computing algorithms and the ability to use our quantum computing systems to run such algorithms represent a combined performance obligation that is satisfied over-time with revenue recognized based on the efforts incurred to date relative to the total expected effort.
Fixed fee arrangements may also include a variable component whereby customers pay an amount for usage over contractual minimums contained in the contracts. We have determined that contracts that contain consulting services related to co-developing quantum computing algorithms and the ability to use our quantum computing systems to run such algorithms represent a combined performance obligation that is satisfied over-time.

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. 68 Quantum computing systems Quantum computing systems are included within property and equipment, net on the consolidated balance sheet.
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.
The increase was primarily driven by interest income earned on our cash equivalents and available-for-sale investments from the investment of the proceeds from the Business Combination.
The increase was primarily driven by interest income earned on our cash equivalents and available-for-sale investments due to higher interest rates. Liquidity and Capital Resources As of December 31, 2023, we had cash, cash equivalents and available-for-sale securities of $455.9 million.
When the standalone selling price is not known, due to it being either highly variable or uncertain, we allocate the transaction price using the residual approach. For contracts with a fixed transaction price, the fixed fee is recognized on a straight-line basis over the access period or associated measure of progress for our consulting services contracts.
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.
Emerging Growth Company Status and Smaller Reporting Company Status Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies are required to comply with the new or revised financial accounting standards.
