Diamond Hill Capital’s decision to initiate a new position in Knowles (KN) after its Q1 2026 review put fresh attention on the stock, linking institutional interest to recent revenue growth and a higher-margin business mix.

The recent 27.49% 1 month share price return and 54.03% year to date share price return to US$33.81, alongside a 106.54% 1 year total shareholder return, suggest momentum has been building as investors reassess growth prospects and risks.

With the stock at US$33.81, a 1 year total shareholder return above 100%, and a price target of US$36.25, the key question is whether Knowles still trades below its potential or if the market is already pricing in future growth.

Price-to-Earnings of 46.2x: Is it justified?

On a P/E basis, Knowles appears expensive, with its 46.2x multiple compared to the current share price context of $33.81, pointing to rich expectations versus peers.

The P/E ratio compares the share price with earnings per share and is often used for companies with a solid profit track record, such as Knowles with its positive net income of $62.6m. A higher P/E usually means investors are willing to pay more today for each dollar of current earnings, often when they expect stronger profit growth ahead or see the earnings as relatively resilient.

Here, the 46.2x P/E is above the peer average of 34.3x and also above the US Electronic industry average of 27.7x, so the stock trades at a clear premium. Compared with the estimated fair P/E of 30.1x, the current level also sits well above where the market could potentially reset if expectations cool, which illustrates how much optimism is already embedded in the price.

Result: Price-to-Earnings of 46.2x (OVERVALUED)

However, the high P/E and large premium to both peers and the estimated fair P/E leave less room for error if growth expectations or margins disappoint.

Another view on value: DCF paints a different picture

While the 46.2x P/E points to an expensive stock, the SWS DCF model is even stricter, with an estimated future cash flow value of $18.93 versus the current $33.81. That gap suggests expectations are doing a lot of heavy lifting. Which yardstick do you trust more?
