Hyliion Holdings Corp. shares soared 26.6% to $4.67 on Friday, capping off an 89.8% jump for the week after the company put out its first-quarter numbers. Traders piled into the small-cap power-tech stock. The shares are now up 153.8% for the year, MarketScreener reports.
Timing is relevant with U.S. markets closed for the weekend. NYSE American’s main session goes from 9:30 a.m. to 4:00 p.m. Eastern on regular days. The next U.S. equity market holiday is Memorial Day, falling on May 25, not Monday.
Hyliion (NYSE American: HYLN) is shifting away from its electric-truck powertrain pitch. The latest filing and earnings materials highlight the KARNO modular power system, which targets military, data-center, and commercial power sectors.
The company on Tuesday said it wrapped up one-time UL safety testing for the KARNO Power Module and signed a non-binding letter of intent with VFG Holdings covering as many as 250 KARNO cores. In total, it now has about 750 cores under non-binding LOIs. These are not firm orders—just indications of intent, with contracts still to come.
Hyliion’s first-quarter revenue jumped to $2.8 million, up from $489,000 last year, with most of that coming from R&D services. Net loss shrank to $11.7 million, compared to $17.3 million a year ago. Operating expenses dropped to $13.4 million from $19.7 million.
Hyliion CEO Thomas Healy said the company made “tangible progress” on its deployment plan this quarter. During the earnings call, Healy called the UL test a “gating item” and said passing it allows Hyliion to begin sending early adopter units to customer sites. Hyliion Investors
Hyliion CFO Jon Panzer called the quarter “a really good start” toward its $10 million 2026 revenue goal. Panzer said current capital can “carry us through commercialization,” but more funding will be needed to scale up production. Investing.com
The peer group is changing. Hyliion’s data center push brings it closer to on-site power names like Bloom Energy and FuelCell Energy and further from the old clean-truck set. Bloom hiked its full-year outlook after better results from digital-power demand. FuelCell Energy is pitching a 12.5-megawatt power-block for data centers. Hyliion isn’t there yet, still early in that process.
Hyliion shares bucked the broader market Friday. The S&P 500 dropped about 1% as rates and oil prices climbed, according to the New York Stock Exchange’s recap, but the index still ended the week a little higher. Hyliion’s action didn’t line up with the rest of the tape, appearing driven by its own story.
On Monday, expect more back-and-forth near $5, not a steady trend. MarketScreener shows two analysts at an average target of $5.00, or about 7% above where shares ended Friday. After last week’s action, the stock is trading close to that target.
Monday’s session could be driven by any new filing, news of a major military contract, a signed VFG purchase deal, or an update on early adopter deployments. If nothing comes out before the open, trade could just track momentum, volume and whether buyers keep support near the $4.67 Friday close.
The risks are clear. Hyliion is an early-stage firm posting ongoing losses. Its VFG customer deals are non-binding, and military contracts are still tied up in government process. Delays in deployment, money flows, supply chain, or defense business could see last week’s run reverse fast.
