Reading a company

Module 2 · 5 lessons · JH Grandgerard

In the first half of 2026, Builders FirstSource reported a net loss of $51.3 million. Its cash flow statement for the same six months shows $155.5 million of cash from operations. Most people stop at whichever figure they see first. The balance sheet complicates both readings: what the company owed its suppliers rose by more than all the cash its operations produced. I went through it in the Builders FirstSource case.

That is why reading comes before judging. Every later measure, from return on capital to what a company is worth, starts from lines in these three statements. The first three lessons take the balance sheet, the income statement and the cash flow statement in turn. The fourth is free cash flow, the cash left over after paying for everything the business needed, and the fifth asks why profit and cash disagree, which is where you read all three together. Each lesson also has a section on where its own advice breaks.

Read one at a time, those six months at Builders FirstSource describe three different companies.
