NOPAT: Definition And Formulae For Net Operating Profit After-Tax And NOPAT Margin

NOPAT - Net Operating Profit After Tax
Share with your friends


Net operating profit after-tax (NOPAT) is the unlevered, after-tax operating cash generated by a business. It represents the true, normal and recurring profitability of a business. GAAP earnings or, even worse, non-GAAP earnings, are highly unreliable and are subject to misleading management manipulation.

As the numerator in our return on invested capital (ROIC) calculation, NOPAT is a very important value, and we place a great deal of importance on getting it right.

When we calculate NOPAT, we make numerous adjustments to close accounting loopholes and ensure apples-to-apples comparability across thousands of companies. A company shouldn’t be able to hide from its mistakes, for instance, hidden, unusual losses.

Figure 2 shows the companies with the most under/overstated GAAP earnings as compared to NOPAT.

Per Figure 2, Entergy Corporation’s NOPAT is $24.8 billion less than its already negative GAAP earnings. Our NOPAT calculation for ETR can be seen here. You can see that due to large losses from unconsolidated subsidiaries, Entergy’s operating expenses were significantly higher than in previous years, which lead to the drastic decline in NOPAT from the prior year.

Novartis (NVS), Lloyds Banking Group (LYG), Chevron (CVX) and GlaxoSmithKline (GSK) also have significantly overstated GAAP net income after adjustments for non-operating expensesexpenses or income hidden in operating earnings, or asset write downs are made. Here’s the Adjustment Page from our model, which shows exactly how we adjust Chevron’s GAAP Net Income to calculate NOPAT. We also show how to convert Total Assets to Invested Capital.

On the other hand, Apache Corp’s (APA) GAAP net income greatly understates its NOPAT. See our NOPAT calculation for APA each year dating back to 1998 here. In 2015, Apache Corp had write-downs totaling over $27 billion. Because asset write-downs are an unusual charge and distort recurring core profitability, we remove them from our NOPAT calculation. To ensure profitability metrics aren’t distorted, our models capture the after-tax value of write-downs in invested capital. Such large write-downs in 2015 may have kept Apache’s NOPAT higher, but they drove down its return on invested capital (ROIC) from 4% in 2014 to -0.4% in 2015.

Chesapeake Energy (CHK), Devon Energy (DVN), General Electric (GE), and Freeport-McMoRan (FCX) each reported GAAP net income that understated the true recurring profits of their business operations as well. See the conversion of General Electric’s GAAP net income to NOPAT here.

Our models and calculations are 100% transparent because we want our clients to know how much work we do to ensure we give them the best earnings quality and valuation models in the business.

Below are the primary accounting distortions in reported financial statements that require economic translation and adjustment for the NOPAT calculation.

  1. Remove asset write-downs hidden in operating expenses
  2. Remove non-operating expenses hidden in operating earnings
  3. Remove non-operating income hidden in operating earnings
  4. Add back change in reserves
  5. Remove income and loss from discontinued operations (except for REITs)
  6. Add back implied interest for the present value of operating leases
  7. Adjust for non-operating tax expenses
  8. Historical adjustments: Add back goodwill amortization prior to 2002 and include employee stock option expense prior to 2006
  9. Remove reported non-operating items

Here are details on the numerous footnotes adjustments to Invested Capital to ensure the best ROIC in the business.

    Re: your formula for NOPAT. After summing to arrive at EBIT, you than add back EBITA. Isn’t this double counting? Wouldn’t the final answer for NOPAT be grossly exaggerated and meaningless? Where am I confused? Thks

    You are correct. The Figure should show “=” EBITA.
    Quite a silly typo – thank you for pointing that out.
