10 Most Undervalued Stocks Under $30 to Buy

7. Cemex (NYSE:CX)

Cemex (NYSE:CX) is one of the most undervalued stocks under $30 to buy. On February 5, Cemex released its financial report for 2025, headlined by double-digit growth in Q4 sales and EBITDA. The company hit its $200 million recurring savings target, which helped expand margins across all regions during H2 of the year. While H1 2025 was hampered by soft demand in the US and headwinds in Mexico, the company’s full-year adjusted net income rose 41% to $1.5 billion, excluding $538 million in goodwill impairments and asset write-downs.

The company’s cash generation remained robust, with free cash flow from operations reaching $1.4 billion at a 46% conversion rate. This financial strength prompted a proposal to increase the annual cash dividend by nearly 40% to $180 million, alongside a new $500 million share buyback program spanning the next three years.

Although potential currency fluctuations and inflation pose risks, Cemex (NYSE:CX) now sees upside potential from its decarbonization efforts in Europe and a possible recovery in Mexican industrial projects following USMCA negotiations. Furthermore, energy costs per ton of cement fell by 12% in 2025, providing a favorable tailwind for sustained margin improvement in the coming year.

Cemex (NYSE:CX), together with its subsidiaries, produces, markets, distributes, and sells cement, ready-mix concrete, aggregates, urbanization solutions, and other construction materials and services worldwide.
