Supermarket Income REIT is trading at £0.69, significantly below its estimated fair value of £0.91, presenting a potential opportunity for investors focused on cash flow valuation. The company's revenue is projected to grow at 5.3% annually, surpassing the UK market average of 3.6%. However, debt coverage by operating cash flow remains inadequate. Despite this, earnings are expected to grow substantially at 48.04% per year as it aims for profitability within three years amidst recent dividend increases.
