Are car companies losing money on electric cars?

Could you elaborate on whether car companies are indeed facing financial losses due to their investments in electric cars? Are these losses a result of the high costs associated with R&D, production, or marketing of these vehicles? Are government incentives and subsidies sufficient to offset these expenses, or are there other factors at play that contribute to potential financial losses? Additionally, is the market demand for electric cars strong enough to sustain profitability in the long run, or are car companies essentially investing in a market that may not yet be fully mature?
