Non-GAAP and Other Financial Measures

Silver Spring believes that its results of operations under generally accepted accounting principles, or GAAP, when considered in isolation, may only provide limited insight into the performance of its business in any given period. As a result, Silver Spring manages its business, makes planning decisions, evaluates its performance and allocates resources by assessing non-GAAP measures such as non-GAAP revenue, cost of non-GAAP revenue, non-GAAP gross profit (loss), non-GAAP operating income (loss), non-GAAP net income (loss), non-GAAP earnings (loss) per share, and adjusted EBITDA, and total backlog, in addition to other financial measures presented in accordance with GAAP. Silver Spring believes that these non-GAAP and other financial measures offer valuable supplemental information regarding the performance of its business, and will help investors better understand the sales volumes, and gross margin and profitability trends, as well as the cash flow characteristics, of its business. The non-GAAP measures should not be considered in isolation from, are not a substitute for, and do not purport to be an alternative to, revenue, cost of revenue, gross profit (loss), operating loss, net loss, loss per share or any other performance measure derived in accordance with GAAP. Silver Spring may consider whether other significant non-recurring items that arise in the future should also be excluded in calculating the non-GAAP financial measures it uses.

Non-GAAP revenue represents amounts invoiced for products for which ownership, typically evidenced by title and risk of loss, has transferred or services that have been provided to the customer, and for which payment is expected to be made in accordance with normal payment terms. Non-GAAP revenue excludes amounts for undelivered products, services to be performed in the future, and amounts paid or payable to customers. Non-GAAP revenue is initially recorded as deferred revenue and is recognized as GAAP revenue when all revenue recognition criteria have been met under Silver Spring’s accounting policies as described in Silver Spring’s filings with the Securities and Exchange Commission. Silver Spring reconciles revenue to non-GAAP revenue by adding revenue to the change in deferred revenue in a given period.

Cost of non-GAAP revenue represents the cost associated with products and services that have been delivered to the customer, excluding stock-based compensation and amortization of intangibles. Cost of product shipments for which revenue is not recognized in the period incurred is recorded as deferred cost of revenue. Deferred cost of revenue is expensed in the statement of operations as cost of revenue when the corresponding revenue is recognized. Costs related to services are expensed in the period incurred. Silver Spring reconciles cost of revenue to non-GAAP cost of revenue by adding cost of revenue to the change in deferred cost of revenue, less stock-based compensation and amortization of intangibles included in cost of revenue, in a given period.

Non-GAAP gross profit (loss) is the difference between non-GAAP revenue and cost of non-GAAP revenue.

Non-GAAP operating income (loss) represents operating loss adjusted for non-GAAP revenue and cost of non-GAAP revenue and excludes expenses related to the amortization of intangible assets, legal settlements, and stock-based compensation.

Non-GAAP net income (loss) represents net loss adjusted for non-GAAP revenue and cost of non-GAAP revenue, and excludes expenses related to the amortization of intangible assets, legal settlements, stock-based compensation, changes in fair value of preferred stock warrant liabilities and embedded derivatives, and loss on extinguishment of promissory notes.

Non-GAAP earnings (loss) per share represents non-GAAP net loss divided by weighted average shares outstanding for the period.

Adjusted EBITDA is net income (loss) adjusted for changes in deferred revenue and deferred cost of revenue, other (income) expense, net, provision for income taxes, depreciation and amortization, stock-based compensation and certain other items management believes affect the comparability of operating results.

Total backlog represents future product and service billings that we expect to generate pursuant to contracts that we have entered into with our utility customers and meter manufacturers. Total backlog includes order backlog, which represents future billings for open purchase orders and other firm commitments.
