Government funding and support through various laws, tax credits, and development grants indicates that public EV charging equipment production will likely continue on a high growth trajectory.

They are based on management’s expectations that involve a number of business risks and uncertainties, any of which could cause actual results to differ materially from those expressed in or implied by the forward-looking statements. Tax adjustments include the net tax benefit/(expense) from one-time income tax items, the set-up or reversal of uncertain tax position reserves and deferred income tax valuation allowance adjustments.
