Besides being in the recycling business which is clearly environmentally positive and something that Americans don't do enough of, Darling's two end products: protein meal for feedstock and industrial oils (including biodiesel) puts it at the rare intersection between today's two hottest sectors: energy and agricultural products.
What's more, I can't find any serious competitors in this sector. There is a Chinese company (GU) operating in the same space but obviously they are geographically distinct. Darling has 24 plants and 19 transfer station -- a considerable amount of infrastructure and simultaneously a significant barrier to entry for any likely competitor.
The stock is trading at a trailing P/E of 26 and a forward P/E of 16, not unreasonable given its profit growth in recent years. However, I can see two negatives. First, the bulk of revenue growth was probably from the increase in the price of end products rather than increased volume (just by eyeballing the numbers). Although I expect the trend of higher prices for its end products to continue, it does subject the company's revenue to the volatility of commodity prices. I would like to see the company having a clear strategy to expand its collection base either organically or through acquisitions, or an expansion into foreign markets. The second negative lies in the fact that the CEO has just sold a chunk of his holdings. All things considered however, I still see the positives outweigh the negatives, such that DAR is likely to be one of my core holdings for a while.
DAR looks strong technically, going the proverbial lower left to upper right. Excursions below the 50 dma have been good places for accumulation. We just had a small bounce from there, if the CEO's sale of stock precipitates more selling I might add to my position.
