Approach 1: Monolithic Power Systems Discounted Cash Flow (DCF) Analysis

A Discounted Cash Flow model estimates what a company might be worth by projecting its future cash flows and discounting them back to today using a required return. It is essentially asking what all those future dollars are worth in present terms.

For Monolithic Power Systems, the model uses a 2 Stage Free Cash Flow to Equity approach. The latest twelve month free cash flow is about $670.5m. Analysts supply detailed forecasts for the next few years, and Simply Wall St extends these out, with projected free cash flow of about $2.0b in 2030. The ten year path includes a range of analyst sourced figures and extrapolated estimates, all converted into today’s dollars using a discount rate.

Based on those cash flows, the DCF model arrives at an estimated intrinsic value of about $580.17 per share. Compared to a current share price of US$1,068.85, this suggests the stock is trading about 84.2% above the model’s estimate of fair value, which indicates a rich valuation on this basis alone.

Result: OVERVALUED

Approach 2: Monolithic Power Systems Price vs Earnings

For profitable companies, the P/E ratio is a useful quick check because it links what you pay for each share to the earnings that the business is currently generating. Investors usually accept a higher P/E when they expect stronger growth or see lower risk, and a lower P/E when growth expectations are more modest or risks are higher.

Monolithic Power Systems currently trades on a P/E of 84.47x. That is above the wider semiconductor industry average of 39.82x and also above the peer group average of 60.43x. To go a step further, Simply Wall St calculates a proprietary “Fair Ratio”, which estimates what a more suitable P/E might be once factors such as earnings growth, profit margins, industry, company size and specific risks are taken into account.

For Monolithic Power Systems, the Fair Ratio is 42.09x, which is lower than the current P/E of 84.47x. Since the current multiple is materially higher than this Fair Ratio, the shares look expensive on this earnings based measure.

Result: OVERVALUED
