Their latest 10Q shows GAAP pretax income of $1.9 billion.
If you're referring to total change in cash which was -$4.2 billion, that's because they reduced their accounts payable by $10.2 billion from paying all the suppliers after the holiday season. Looking at the consolidated statement of cash flows of a seasonal business very, very easily leads to misunderstanding the business.
Operating cash flow was $18 billion for the year ending 3/31.
Long-term debt was $3bn in 2013, increasing to $8bn in 2014 and $25bn in 2017. Capital leases have also gradually increased from $2bn in 2013 to $8bn in 2016 and $13bn in 2017.
The three different cash flow calculations in 2012-2015 were $4.4bn (0.4+2+2), $1.7bn (-0.1+1.3+0.5) and -$2.4bn (-0.4+0.2-2.2).
As forecasted, the divergence of these metrics has continued.
That's a huge distinction, if you start having to raise more debt or equity in order to fund your growth it's going to negatively impact the long term free cash flow per share of your business and will make it harder for your to generate outsized returns.
