Power systems manufacturer PSIX has experienced rapid revenue growth, with power systems sales increasing 47% sequentially and 115% year-over-year in the second quarter of 2025. The company, which produces diesel and gas engines for data centers among other business lines, reported a year-over-year EBITDA growth of approximately 60%, reaching a run rate of around $150 million. PSIX is expanding its manufacturing capacity to meet rising demand, supported by engine supplies from Weichai that competitors currently cannot match. Despite this rapid growth, PSIX has maintained strong cash flow conversion, turning earnings almost fully into free cash flow. The company's enterprise value stands at about $2.5 billion, trading at a multiple of 16-17 times EBITDA, which analysts suggest could rise to 25 times given continued growth prospects. Meanwhile, in Baltimore, a substation failure linked to a major power plant has prompted the largest US grid operator to order emergency power usage reductions to prevent widespread blackouts. Over a million residents have been warned by the local utility, MyBGE, to conserve electricity as the city faces potential power outages.
