3 Quality Compounders with Impressive Fundamentals

META Cover Image

Quality compounders are well-oiled machines. Their competitive advantages allow them to make profits consistently and reinvest them into projects that generate even more profits, creating a virtuous cycle of returns.

Companies with these characteristics are our definition of a "blue-chip". On that note, here are three quality compounders that could amplify your portfolio’s returns.

Meta (META)

Market Cap: $1.77 trillion

Famously founded by Mark Zuckerberg in his Harvard dorm, Meta Platforms (NASDAQ: META) operates a collection of the largest social networks in the world - Facebook, Instagram, WhatsApp, and Messenger, along with its metaverse focused Reality Labs.

Why Is META a Good Business?

  1. Monetization efforts are paying off as its average revenue per user has grown by 13.3% annually over the last two years
  2. Highly efficient business model is illustrated by its impressive 59.9% EBITDA margin, and its profits increased over the last few years as it scaled
  3. Impressive free cash flow profitability enables the company to fund new investments or reward investors with share buybacks/dividends

At $696.30 per share, Meta trades at 15.9x forward EV/EBITDA. Is now the time to initiate a position? See for yourself in our full research report, it’s free.
