Notes on these figures

  • The share price has fallen 44% since Aug 5, 2026, when the 10-Q these figures come from was filed ($1.71 then, $0.95 on Nov 13, 2026). The figures date from before that move.10-Q
  • Most of the reported profit is a tax credit, not money earned from customers. We leave out the P/E and the earnings growth, which would not compare with a company that paid tax.
  • Profit over the last twelve months is well above what the business itself earned, because it includes large gains outside the business, such as on investments or from selling a business. The P/E is lower than the business alone would give.
