What Do These Terms Mean?
EPS (Earnings Per Share):
Quarterly profit divided by the total share count — how much of the profit works out to a single share.
YoY (Year over Year):
Change versus the same quarter a year ago — this is how you compare without seasonal distortion (e.g. the holiday shopping season).
Sales:
All revenue for the quarter, before any costs are deducted — the top line of the income statement.
Net Margin:
What percentage of sales is left over as profit in the end. Negative means the company is posting a loss.
OCF (Operating Cash Flow):
The cash that actually flows into the till from the core business during the quarter — harder to dress up than book profit.
FCF (Free Cash Flow):
Operating cash flow minus capital expenditures — the money that's genuinely free to use, say for paying down debt, buybacks, or dividends.
