Uber Technologies, Inc. and Lyft, Inc. both merit Buy ratings, with Uber favored for its scale, diversification, and AV transition positioning. UBER's global reach, diversified revenue, and robust free cash flow (~$10B TTM) provide significant strategic and financial advantages versus LYFT. LYFT's U.S. concentration (95% of revenue) exposes it to AV disruption risk, but its low valuation (adj. P/FCF ~7.2) reflects this.
