Non-GAAP and Other Financial Metrics

Silver Spring Networks supplements the results of operations presented in accordance with generally accepted accounting principles, or GAAP, with certain non-GAAP metrics. Silver Spring Networks manages its business, makes planning decisions, evaluates its performance and allocates resources by assessing non-GAAP and other financial metrics such as billings, cost of billings, non-GAAP operating expense, and total backlog. Silver Spring Networks believes that these non-GAAP and other financial metrics, when taken together with the corresponding GAAP financial measures, offer valuable supplemental information regarding the performance of its business, and will help investors better understand the sales volumes and profitability trends, as well as the cash flow characteristics, of its business. The non-GAAP metrics 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, operating expense, or any other performance measure derived in accordance with GAAP. Silver Spring Networks 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.

Billings 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. Billings excludes amounts for undelivered products, services to be performed in the future, and amounts paid or payable to customers. Billings are initially recorded as deferred revenue and are then recognized as revenue when all revenue recognition criteria has been met under Silver Spring Networks’ accounting policies as described in Silver Spring Networks’ filings with the Securities and Exchange Commission. Silver Spring Networks reconciles revenue to billings by adding revenue to the change in deferred revenue in a given period.

Cost of billings represents the cost associated with products and services that have been delivered to the customer, excluding stock-based compensation, amortization of intangibles and acquisition-related charges. 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 Networks reconciles cost of revenue to cost of billings by adding cost of revenue and the change in deferred cost of revenue, less stock-based compensation, amortization of intangibles and acquisition-related charges, included in cost of revenue in a given period.

Non-GAAP operating expense consists of research and development, sales and marketing, and general and administrative expenses, excluding amortization and impairment of intangible assets, stock-based compensation, acquisition-related charges, restructuring and legal settlements.

Total backlog represents future product and service billings that Silver Spring Networks expects to generate pursuant to contracts entered into with its utility customers and meter manufacturers. Total backlog includes order backlog, which represents future billings for open purchase orders and other firm commitments.
