Preformed Line Products (PLPC) shares recently climbed 4.9% on what is described as strong company performance, even as the stock is flagged as significantly overvalued relative to its estimated intrinsic value by GF Value assessments.

That 4.9% one day share price return comes on top of a 40.3% 90 day share price return and a 1 year total shareholder return of 159.9%, indicating recent momentum even as valuation appears stretched.

With PLPC trading close to its US$372 price target and at a premium to its estimated intrinsic value, you have to ask: is there still mispricing here, or is the market already banking on years of future growth?

Price-to-Earnings of 51x: Is it justified?

On a simple P/E view, Preformed Line Products looks expensive, with a 51x multiple at the last close of $357.82 compared with both peers and its own fair ratio.

The P/E ratio compares the current share price to earnings per share and, for PLPC, sits at 51x. For an electrical equipment manufacturer with $697.08m of revenue and $34.29m of net income, that is a rich earnings multiple that implies the market is willing to pay a high price for each dollar of current profit.

Some investors may see that as the market pricing in the forecast 21% annual earnings growth. Others may question whether such a premium is warranted given that earnings are reported to have declined 0.4% per year over the past 5 years and return on equity is described as low at 7.2%. The large one off loss of $11.7m in the last 12 months and lower net profit margin of 4.9% compared with 6.5% a year earlier also add context to how those earnings are currently being generated.

Compared with a peer average P/E of 37.4x and a US Electrical industry average of 38.1x, PLPC trades on a meaningfully higher multiple. It is also described as expensive versus an estimated fair P/E of 30.3x, a level some investors may view as a potential reference point if sentiment or growth expectations cool.

Result: Price-to-Earnings of 51x (OVERVALUED)

However, that premium P/E and a 3.1% premium to estimated intrinsic value leave little room if earnings forecasts soften or if sector sentiment toward electrical equipment cools.

Another View on Value

While the 51x P/E suggests PLPC is expensive, the SWS DCF model points to an even starker picture, with the stock at $357.82 compared with an estimated future cash flow value of $87.09. This raises the question of whether recent momentum is running ahead of fundamentals.
