Competitiveness and MOAT

High margins render the company resilient under dire circumstances, hence able to drive competitors out or acquire them. ROE and ROA measure the average flow generated by each invested dollar. Their marginal value is a forecast of future growth, and it is considered by Buffett and Munger the most important single indicator.

ROE	-	4%	-2%	-8%	-17%	-15%	4%	-1%

Bad Net Margins (-29.38%)

Net Margins are too low to guarantee profitability in case of higher costs or higher interest rates. Furthermore lower margins cause higher earnings’ volatility.

Safety and Stability

Being debt the number one cause of investment losses and company death, the ratio Debt/FCF is of utmost importance to guarantee safety. On the other hand the Graham’s stability measures the drawdown of earnings, hence indicating the reliability of the flow generated by the company.

Years	12/2018	12/2019	12/2020	12/2021	12/2022	12/2023	12/2024	TTM
Debt over FCF	-	5.35	0	-	-	-0	0.29	0.27
Debt over Equity	-0.43	0.38	0	-	-	0	0.02	0.03
Growth Stability	-	-	-	-	-	-	-	1

Good Debt/FCF ratio (0.27)

Net Margins are high enough to offer a good protection on the profits in case of higher costs or higher interests. Furthermore higher margins reduce earnings’ volatility.

Good Debt/Equity ratio (0.03)

The company is not overleveraged and has a good balance between equity and debt.

Good Graham’s Stability (1)

The company has a good stability in its earnings, which is a sign of a good competitive advantage.

Growth

Growth can be dangerous when forecasting, simply projecting the current growth is in general wrong. A company passes through multiple phases, from being young and unprofitable, to the first periods of profitability and high growth, until it arrives at a period of regime with limited growth. Identifying in which phase the company is in may help forecasting.
