HEICO (HEI) Could Be 17% Undervalued Following Rising Earnings Expectations

Simply Wall St · 1d ago

HEICO (HEI) is back in focus after being flagged among defense stocks that are expected to beat quarterly earnings forecasts, with its aerospace aftermarket, defense and space exposure, backlog, and EthosEnergy acquisition drawing investor attention.

Recent trading has been choppy for HEICO, with the share price rising 8.6% over the past week and 12.0% over the last month, yet still down 7.1% over ninety days, as investors weigh stronger earnings expectations, defense and space demand, and ongoing integration of EthosEnergy.

At the latest share price of US$337.67, that pattern of short term share price momentum sits alongside a 2.5% year to date share price gain and a 6.2% total shareholder return over one year, compared with much larger total shareholder returns over three and five years that reflect a longer history of compounding for investors.

After that sharp rebound in HEICO and a richer earnings story, the real question now is simple: does the current price still leave enough upside to justify the risks you are taking on the valuation?

Most Popular Narrative: 14% Undervalued

HEICO’s most followed narrative pegs fair value at $393.70 against the latest close of $337.67. The story centers on whether investors are willing to back that gap with the company’s current growth, margin profile, and acquisition firepower.

The main thing that has to go right is that HEICO continues to convert its enlarged acquisition pipeline and expanded credit capacity into high margin, cash generative deals that stay accretive within a year. At the same time, it needs to maintain the higher margin framework now outlined for Flight Support Group and Electronic Technologies Group.

The current valuation implies investors are paying a premium for HEICO’s record profitability, cash generation, and long term net income growth ambitions despite share price volatility after recent results. This is consistent with a view that the stock is still undervalued.

See why 26 investors see HEICO as 14% undervalued.

Result: Fair Value of $393.70 (UNDERVALUED)

Still, the HEICO narrative can break if supply chain bottlenecks slow backlog conversion or if future acquisitions dilute margins instead of reinforcing them.

Another View: HEICO Through The P/E Lens

The DCF workup suggests HEICO is undervalued, yet the market’s own P/E yardstick tells a tougher story. At roughly 55.7x earnings, the stock trades far above the US Aerospace & Defense average of 29.7x and well above an estimated fair ratio of 28x. That kind of gap points to meaningful valuation risk if sentiment or growth expectations cool. Investors may therefore want to consider how comfortable they are paying more than double what the fair ratio suggests.
