ECMSource Research Workbench · Company fundamentals
Turn comparable quarterly figures into a compact diagnostic: growth, operating-margin direction, cash conversion, and diluted share-count change.
Enter reported figures
Use the same units throughout—millions or billions both work. Use diluted weighted-average shares for both share-count fields. Profit and cash-flow values may be negative.
Interpret these results with the filing notes and management discussion. A calculated change is not automatically positive or negative for the investment.
Read the result carefully
Sequential growth compares the current and immediately preceding quarters. Seasonality can make this misleading on its own.
Operating margin uses operating income divided by revenue. Confirm that both periods use comparable accounting presentation.
Cash conversion compares operating cash flow with net income for one quarter. It is marked not meaningful when net income is zero; losses also require contextual interpretation.
Share-count change can reveal dilution, but the weighted-average count may lag a recent issuance.
Where to find the inputs
Use a company’s income statement and cash-flow statement from its earnings release or SEC filing. Cite the exact periods when saving or sharing your work.
Revenue growth = current revenue / comparison revenue − 1
Operating margin = operating income / revenue
Cash conversion = operating cash flow / net income
Share-count change = current diluted shares / year-ago diluted shares − 1
