Sprint didn't actually earn $7.38 billion in net income from operations in 2018 (their operating income was $2.46 billion that year, their debt interest cost alone was $2.36 billion). They got a one-time tax benefit in that fiscal year, for $7.1 billion, due to the tax law changes. Their business is a disaster because of the debt. ~$9.5 billion in debt interest costs in the last four years.
