Write a one-page investment memo on a PVC pipe maker trading at 32x earnings, with revenue of Rs 3,100 crore, 30,000 dealers and resin prices that swing 25% a year. What goes in each section?

The memo's view: a quality franchise priced for about 18% EPS growth, so hold off at 32x and look again on a resin-led dip. The thesis is the 30,000-dealer network, which lets Grevanto grow volumes near 15%. The valuation shows 15% EPS growth earns only 9.5% a year from here, below a 12% cost of equity. Each risk gets a trigger: a resin fall of 15% or more in a quarter, stalling dealer additions, or a rival adding capacity.

The view, in one line, before any history. A reader who stops after the first sentence should know what you think and why. A memo leads with the view and gives each risk a trigger to watch; everything between exists to support those two. Grevanto's line: a quality franchise priced for about 18% EPS growth, so the price, not the business, is the issue. Minto's pyramid principle, answer first and support after, is the structure most fund managers expect.

One number the reader can check next quarter. 30,000 dealers selling Rs 10.3 lakh of Grevanto pipe each a year is the moat: a plumber asks for the brand, the dealer stocks it, and a new entrant has to win both. Growth comes from adding dealers in smaller towns and from housing and irrigation demand. Resin is a cost that swings, not a thesis; Grevanto passes it on within weeks, so it moves quarterly margins, not the long-run story. Think of a milk cooperative whose collection network is the asset, whatever the price of fodder does in any one season.

What the price assumes, not just the multiple. At Rs 320, a 12% annual return with an exit at 25x needs EPS of Rs 22.5 in five years. That is 17.7% EPS growth a year; at management's 15%, the return is 9.5% a year, short of a 12% cost of equity. So the stock is fairly to fully priced: a buyer at 32x is paying today for growth above the company's own target. The de-ratingA fall in the multiple investors pay for each rupee of earnings, independent of any change in the earnings themselves. from 32x to 25x is doing the damage; if the multiple held at 32x, 15% growth would return 15% a year.

Give each one a trigger you could see in a monthly or quarterly update. Resin: a fall of 25% would force a write-down of about Rs 53 crore on 45 days of stock, 13% of a year's EBITDA, so the trigger is a resin fall of 15% or more in a quarter. Distribution: dealer additions falling below the pace needed for 15% volume growth. Competition: a rival announcing capacity in Grevanto's core states. Close the memo with the monitor list: resin prices monthly, dealer count and volume growth quarterly, and working capital days, which show whether growth is being bought with dealer credit.
