Rare-earth miner MP Materials reported second-quarter revenue of $57.4 million, an 84 percent jump from a year earlier and well ahead of analysts’ roughly $46 million consensus. The company posted an adjusted loss of 13 cents a share, beating expectations for a loss of 18–20 cents, while its adjusted EBITDA deficit narrowed to $12.5 million from $27.1 million. Net loss improved to $30.9 million from $34.1 million in the year-earlier period. The stronger-than-expected results sent MP Materials’ stock up about 9 percent in post-market trading to $77.64, extending a 3.6 percent gain earlier in the day after Jefferies upgraded the shares to Buy. Options pricing had implied a move of roughly 7.4 percent ahead of the earnings release.
