01

Start with the difference you want to explain

A company can publish both GAAP net income and an adjusted profit figure for the same quarter. Your first task is to explain the difference between them. Choosing the larger figure does not answer that question. This guide gives you a repeatable worksheet for following the reconciliation from one measure to the other.

GAAP refers to generally accepted accounting principles. A non-GAAP measure changes the treatment of specified amounts relative to a comparable GAAP measure. The company’s definition matters. Two figures called adjusted earnings may not use the same exclusions, so the label alone is not enough for a comparison.

Start from ThesisMemo and open the company research you are reviewing, then follow the available original-source links. Keep this worksheet in your own document or spreadsheet. The steps below are a manual reading method, not a claim that ThesisMemo automatically reconstructs every reconciliation or stores your worksheet.

02

Find the reconciliation before copying the headline

Open the issuer’s earnings release or supplementary presentation and search for reconciliation, non-GAAP or adjusted. Confirm that the document belongs to the company and reporting period you intended to study. Save the document title, publication date, link and table heading in your worksheet before entering any numbers.

Write the exact starting and ending measure names. A bridge from net income to adjusted net income is different from one starting with operating income. Preserve whether the amounts apply to the consolidated company, a segment or income attributable to a particular ownership group. That prevents a correctly copied number from entering the wrong comparison.

If you cannot locate the bridge, check the accompanying schedules and the company’s investor-relations materials. Mark the comparison unresolved if the evidence remains unavailable. Do not manufacture a reconciliation by combining unrelated expense figures simply because their sum happens to approach the difference between the two headlines.

03

Build a worksheet that makes every sign visible

Create columns for the row label, amount, unit, direction, explanation and source location. Put the reported starting value first. Add one row for each disclosed adjustment and the adjusted ending value last. Keep tax effects in their own row when the company presents them separately.

Use the direction shown by the issuer’s table. Removing an expense and removing a gain need not move the result in the same direction. Copying every adjustment as a positive number is an easy way to produce a result that looks plausible but cannot be reproduced from the source.

Add a separate arithmetic-check cell: starting value plus the signed adjustments minus the ending value. It should equal zero apart from explainable rounding. If it does not, inspect the transcription, units, signs and missing rows before interpreting the business. A successful sum establishes that your worksheet matches the table; it does not establish that every exclusion is useful.

04

Practice with a fully hypothetical earnings bridge

Consider a fictional company, Harbor Devices. These invented figures do not describe NVIDIA, AMD, Palantir or any other listed business. Assume its reconciliation begins with quarterly GAAP net income of $80 million. It adds $12 million of one expense and $8 million of another, then subtracts a $5 million tax-effect adjustment.

The resulting adjusted net income is $95 million: 80 + 12 + 8 − 5 = 95. The gap is $15 million. Dividing that gap by the $80 million GAAP starting point gives 18.75%. That is the size of the adjustment relative to the starting value, not a year-over-year profit growth rate.

Now suppose you accidentally omit the tax row. Your worksheet produces $100 million and fails the check by $5 million. Repairing that row is more useful than writing an explanation for a number the company never reported. In a real filing, retain the issuer’s actual adjustment descriptions instead of the generic expense labels used in this exercise.

05

Compare two periods on a consistent basis

Extend the fictional example with a prior-year GAAP result of $70 million and adjusted result of $84 million, both for the matching quarter. GAAP profit rises by $10 million, approximately 14.3%. Adjusted profit rises by $11 million, approximately 13.1%. Each calculation uses its own prior-year denominator.

Comparing the current adjusted $95 million with the prior GAAP $70 million produces approximately 35.7%, but mixes two measurement bases. Do not label that number profit growth. Keep two parallel comparisons and investigate why they differ. Here, the reconciliation gap increased from $14 million to $15 million; that observation still needs the underlying rows to explain it.

Before using this structure with real disclosures, check whether the company changed its adjustment policy or revised comparative figures. The SEC’s non-GAAP guidance identifies inconsistent treatment across periods as a potential problem. Record any disclosed change and its explanation rather than silently stitching together a history that uses different definitions.

06

Turn each exclusion into a specific research question

Once the arithmetic works, add a question beside each material adjustment. What activity produced this amount? Where does management explain it? Does the same type of item appear in earlier reconciliations? Which document would let you investigate its business significance? These questions are more informative than assigning every adjustment a universal good or bad label.

For an item described as unusual, open the explanation and compare earlier periods. Do not convert that description into a promise that the item will never happen again. For an acquisition-related item, note the relevant transaction and stated accounting treatment before assuming that all acquisition adjustments have the same meaning.

Treat a reconciled total and a convincing interpretation as separate achievements. You may be able to reproduce the number while remaining uncertain about its relevance. Write that uncertainty explicitly. Your note can conclude that the arithmetic is verified and that one exclusion needs further investigation, without making a recommendation about the stock.

07

Keep earnings, cash and per-share figures separate

The SEC’s financial-statement guide distinguishes profit reporting from cash movements. An adjusted profit figure is not automatically cash generated by the business. If your question concerns cash, open the cash-flow statement and follow that question separately. Do not rename the adjusted total cash earnings merely because some excluded expenses are described as non-cash.

Likewise, a net-income bridge does not by itself reproduce an earnings-per-share bridge. In a worksheet about EPS, use the issuer’s corresponding per-share reconciliation and check the share basis. Do not divide a total-profit adjustment by an unrelated share count copied from a quote page and assume the result matches diluted EPS.

You can preserve both follow-up questions without expanding the current exercise indefinitely. Mark cash conversion and per-share reconciliation as separate tasks, with their own source locations. Finish the net-income bridge first, then decide which additional question matters to the company research you originally opened.

08

Bring a checked observation back to your research

Return to the relevant ThesisMemo assessment and check its review date. If a factor discusses profitability, identify which measure and period support that statement. Your worksheet should help you test a specific observation, not replace the company’s entire story with whichever profit measure looks more attractive.

Write a short closing note using three sentences. First, state the reported and adjusted figures with the period and source. Second, name the largest verified contributors to the difference. Third, identify the unresolved question that would change your interpretation. Keep management’s explanation attributed to management and your own inference labeled as such.

Save the original worksheet and add the next quarter beside it when new evidence arrives. Preserve the earlier definitions and sources so that you can detect a change in treatment. A useful outcome is a traceable comparison that another reader can reproduce, even when the evidence does not support a simple verdict.

Questions & answers

Is adjusted profit always more useful than GAAP profit?

No single label establishes usefulness. Read the comparable GAAP measure, the reconciliation and the company’s explanation together. Decide what question the adjusted measure helps answer and which costs or other effects it leaves outside that view.

Does a reconciliation that adds up prove the presentation is reliable?

It proves only that the arithmetic you copied reconciles. You still need to examine the definitions, period consistency and explanations. The SEC’s guidance notes that reconciliation and detailed disclosure do not automatically prevent a non-GAAP presentation from being misleading.

Should I calculate the tax adjustment with a standard tax rate?

Use the tax-effect row and explanation actually disclosed for the reconciliation. Do not replace a missing value with an assumed rate and present the result as reported. Label an unavailable component unresolved until you can verify it.

Can ThesisMemo save this reconciliation worksheet for me?

This tutorial uses an external document or spreadsheet for the worksheet. Use ThesisMemo to revisit the relevant company research and available sources. It does not assume a built-in reconciliation editor, worksheet storage or automatic approval of the adjustments.

What should I do when the two periods use different definitions?

Record the change and look for comparable figures or an explanation in the issuer’s materials. If you cannot establish a consistent basis, retain the two observations separately and leave the growth comparison unresolved instead of forcing a single percentage.
