Profit After Tax (PAT)

When a company announces its quarterly results and the headline screams 'net profit rose 20%', the number it's quoting is almost always Profit After Tax (PAT). Also called net profit or the bottom line, PAT is what remains of a company's revenue after *everything* has been paid — operating costs, depreciation, interest on debt, and taxes. It is the final measure of what the business actually earned for its shareholders.

Where It Sits in the Accounts

The income statement flows downward: Revenue minus operating expenses gives EBITDA; subtract depreciation and amortisation to get EBIT (operating profit); subtract interest to get profit before tax (PBT); and finally subtract corporate tax to arrive at PAT. Each step strips out another layer of cost, so PAT reflects profitability after the full cost of running the business, financing it, and paying the government.

Why PAT Drives Valuation

PAT is the foundation of the two most-watched metrics in equity markets. Divide PAT by the number of shares and you get Earnings Per Share (EPS); divide the share price by EPS and you get the Price-to-Earnings (P/E) ratio — the dominant way Indian stocks are valued. PAT growth is what the market ultimately pays for, which is why a results-day surprise in net profit can swing a stock sharply. India's corporate tax cuts in 2019 (which slashed the rate for many companies) directly boosted PAT across the market, illustrating how tax policy flows straight to the bottom line.

Reading It Carefully

Smart investors don't take PAT at face value. They check for one-off items — gains from selling assets, exceptional write-offs, or tax credits — that can inflate or depress a single quarter's PAT without reflecting the core business. They compare PAT margin (PAT as a percentage of revenue) across years and peers, and watch whether profit growth is driven by genuine operating strength or by lower interest and tax. They also cross-check PAT against cash flow, since accounting profit and actual cash can diverge. PAT is the headline, but understanding *how* a company arrived at it is the real skill in reading results.
