For example, the non-GAAP adjustment for stock-based compensation expense requires additional inputs such as the number and value of awards granted that are not currently ascertainable, and the non-GAAP adjustment for amortization of acquired intangible assets depends on the timing and value of intangible assets acquired that cannot be accurately forecasted. 21#22Sell-Side Analyst Q&A#23GAAP-to-Non-GAAP Reconciliation#24A GAAP to Non-GAAP Reconciliation Ⓒ2022 Amplitude Inc.
