New York, May 29, 2026, 04:17 (EDT)
Power Solutions International Inc. is set to open Friday at $41.99 on Nasdaq after dropping 1.98% Thursday. That’s another slip in a month that’s wiped almost 43% off the engine stock. The shares have gained 6.06% in the last five sessions, but they’re still off 26.51% for 2026.
That’s the key issue here. PSIX is looking for support as shares adjust lower. Investors are focused on one big question: can sales to data-center customers balance out slower oil-and-gas demand and rising plant expenses?
Then-CEO Dino Xykis said earlier this month that first-quarter numbers lagged last year’s strong results, but said demand in data center business “remains solid.” Power Solutions International pointed to production costs and shipment timing as factors that hurt the quarter.

The stock lagged even as the broader market stayed strong. Reuters said the S&P 500 and Nasdaq ended at new highs Thursday, helped by AI bets and hopes for a U.S.-Iran ceasefire extension driving more risk buying.
U.S. stocks trade as usual Friday. The Nasdaq’s main session is scheduled for 9:30 a.m. to 4:00 p.m. Eastern. Memorial Day is set for May 25 on its 2026 holiday calendar, not May 29.
Power Solutions’ investor-relations site continued to show the May 11 Q1 release as its most recent update. The stock traded on price moves and mid-May reports, with no new statements from the company.
Q1 results were weak. Net sales slid to $128.6 million from $135.4 million last year. Net income dropped to $7.3 million, down from $19.1 million, and diluted EPS was 32 cents, down from 83 cents. Gross margin came in at 22.9%, off from 29.7%.
Power systems lagged last quarter. The company reported a $10.2 million drop in sales for that end market, blaming weaker oil-and-gas demand, lumpy orders from customers, and shipment timing on data-center products.
Management turnover weighed on the stock. A filing from May 13 said Constantine “Dino” Xykis stepped down as CEO as of May 12. The board picked Chief Financial Officer Xun “Kenneth” Li to serve as interim CEO during the search for a permanent hire. Li, 56, has held the CFO post since August 2022 and has finance experience at Caterpillar and Ford, according to the filing. Power Solutions International, Inc.
Power Solutions International, Inc. (PSI) builds emission-certified engines and power systems for industrial, power generation and transportation use. The company sells products for standby and prime power, as well as microgrids, which are local power networks. PSI is also active in the data-center market.
Peers traded mixed in late U.S. quotes. Cummins added $0.57 to $668.68. Generac lost $1.22 to $279.45. Both are power-equipment names that investors track for engine and backup-power demand. There wasn’t a clear sector move to point to.
The downside case is clear. Margins might take longer to bounce back if data-center shipments get delayed, oil-and-gas demand remains weak, or Wisconsin plants can’t lift throughput — the rate factories fill orders with finished goods. Supply-chain issues, tariffs, litigation, and regulatory inquiries are other risks management flagged that could shift results.
Management hasn’t given full-year guidance. It’s calling for second-quarter revenue about in line with the first quarter and expects a pickup in the second half as larger Power Systems orders hit production. But it cautioned that there’s no guarantee those orders will lead to a clearly stronger second half.
