Gentex (Nasdaq: GNTX) is a supplier of dimmable mirrors for the auto and airline industry. Its products are commoditized and require nothing more than plastic moldings, mirrors, chemicals, printed circuit boards, and other inputs such as compasses. Its financials suggest it to be a wildly profitable company, yet our forensic analysis uncovers numerous red flags to suggest otherwise.
Gentex’s IPO in the early 1980s is littered with red flags. Its dimmable mirror was a carrot to bail out its struggling smoke detector business, and its management put no capital at risk. Gentex’s success has defied all the odds: it now commands a $5bn market cap and claims >90% market share. Its lead IPO underwriter and banker, OTC Net founded by Juan Carlos Schidlowski, was a notorious penny stock promoter who was later charged by the SEC and fled the country.
Gentex’s 40% gross margins are vastly superior to all global auto suppliers and are likely overstated by 2x. We believe it’s aggressively leaving costs in inventory (inventory growth is 3x revenue growth) while inflating capex through nonsensical projects (e.g. its North Riley Campus is 90% over initial budget). We commissioned a product tear down by IHS, an automotive expert, to examine its components. In our view, Gentex’s rhetoric pertaining to its mirror’s level of proprietary components and vertical integration is likely exaggerated. We also have documented proof of capex misstatement.
Despite margins and profitably that dwarfs auto supply peers, Gentex policies that are touted as shareholder friendly are not what they appear. Its dividend growth has been well below the rate of its reported free cash flow growth, which is likely overstated, and its share repurchases are mostly to offset dilution. Gentex has amassed an abnormal amount of cash on its balance sheet, and has irregular Level I and II classifications. We believe Gentex has shunned M&A to avoid outside scrutiny. The only acquisition of note in its history was of HomeLink, a related-party deal where we find issues.
