Advanced Drainage Systems is rated a Buy due to its strong secular growth, improved business mix, and benefits from recent acquisitions. The company is growing revenue by gaining market share in thermoplastic pipes and shifting towards higher-margin allied and wastewater products, which now make up 48% of its revenue. Its acquisition of NDS expands its distribution channels and offers significant cross-selling and cost synergy opportunities, supporting future margin and revenue growth. These factors position the company well for medium- to long-term investment gains.
