Given that RFT’s growth is being driven by the EV charging segment which represents 70% of it’s revenue (as per 1H19 results) I’m only going to address this Bull Case on that market.
According to the 2018 market research report "Electric Vehicle Charging Stations Market by Charging Station (AC Charging Station, DC Charging Station), Installation Type (Residential, Commercial), and Region (North America, Europe, Asia Pacific, and Row) - Global Forecast to 2023", the electric vehicle charging stations market is expected to grow from USD 5.30 Billion in 2018 to reach USD 30.41 Billion by 2023, at a CAGR of 41.8% between 2018 and 2023. Key factors such as government funding, subsidies, and incentives, growing demand for electric vehicles, growing concern toward environmental pollution, and heavy investment from automakers of EVs are driving the electric vehicle charging stations market.
DC charging stations, which require AC to DC rectifiers, held the largest share of the electric vehicle charging stations market in 2017. Active participation from EV manufacturers in expanding DC charging networks for EV owners is one of the primary factors for the high market share of DC charging stations. DC fast charging installations are expected to continue to hold the largest share of the electric vehicle charging stations market between 2018 and 2023.
While RFT’s rectifiers are a sub-component for DC EV chargers so their TAM is smaller than the numbers given above, this is still a large and extremely rapidly growing market providing huge upside potential for RFT if their EV charging OEM partners can capture even a small percentage of it. The “rising tide lifts all ships” as they say.
