New York, May 29, 2026, 08:03 (EDT)
- PRF Technologies shares (Nasdaq: PRFX) jumped 235.01% to $4.59 in premarket trading after closing at $1.37. Premarket trading happens before the main U.S. session opens.
- The announcement came after the company gave a May 28 update on DeepSolar Predict, its AI platform for optimizing renewable-energy revenue, which is moving toward a commercial launch.
- PRFX is still a thinly capitalized, high-risk name. A recent SEC prospectus flagged potential resale of as much as 3 million ordinary shares and included a warning about potential dilution.
PRF Technologies Ltd. stock jumped in U.S. premarket trade Friday after the Israeli microcap said it was moving forward with DeepSolar Predict, its AI platform for renewable-energy operators. Shares of PRFX were quoting at $4.59 on Webull at 07:57 EDT, a gain of 235.01% from the last closing price.
Timing is key here. Nasdaq’s main session hadn’t started yet; premarket hours run from 4:00 a.m. to 9:30 a.m. Eastern, with regular trading starting at 9:30 a.m. and ending at 4:00 p.m. The exchange’s 2026 holiday calendar lists Memorial Day, May 25, as a closure, but May 29 is not on the holiday list.
PRFX finished Thursday at $1.37, gaining 1.48%. StockAnalysis put the company’s market cap at roughly $1.19 million and showed 868,756 shares out. That puts PRFX firmly in microcap territory, where thin trading can send the price sharply higher or lower.
PRF said Thursday it is working on DeepSolar Predict, a platform that will use AI forecasting, storage planning and market decision support for wind, solar and battery storage. The company said DeepSolar Predict is designed to help operators sharpen forecasts, manage energy commitments and lower what it calls “imbalance exposure”—the risk tied to mismatches between promised and actual power delivery.

Chairman Dr. Ehud Geller said in the company’s statement that “Renewable energy operators are no longer managing only production” and now have to handle financial exposure too as power markets move faster. GlobeNewswire
PRF is working to shift away from its specialty pharma roots. The website now says PRF is focused on both specialty pharma and an AI-powered renewable energy platform. PRFX closed at $1.37 on May 28 with daily volume over 4 million shares, according to the investor page.
Drug pipeline is still a key issue for investors. PRF said May 26 that PRF-110, its main drug candidate, showed 72-hour pain relief in a preclinical pig trial. The pain relief was similar to Zynrelef, an approved Heron Therapeutics drug, which PRF used as a benchmark in the study. PRF said Zynrelef was only a comparator and it has no connection with Heron.
“For physicians, the key question is whether a new non-opioid therapy can provide sustained pain relief,” Geller said in the release. PRF described PRF-110 as a ropivacaine-only formula without NSAIDs, or non-steroidal anti-inflammatory drugs. GlobeNewswire
PRF’s DeepSolar push drops it into an already packed field of renewable-energy software, where asset owners want platforms that tie together weather, grid limits, storage and pricing. PRF didn’t cite any new customer in its update Thursday, but said DeepSolar has run through work on solar analytics, due diligence, commercial deals and forecasting tech.
PRF is trading on outlook before results are in. The company’s latest release was heavy on forward-looking statements about moving DeepSolar Predict toward commercialization. It’s a warning too: PRF says real results could be very different. It listed risks like needing more cash, ongoing losses, development uncertainty, and its ability to keep its Nasdaq spot.
Dilution keeps weighing on PRF. According to a May 19 SEC prospectus, PRF disclosed it might get as much as $10 million from selling ordinary shares to YA II PN under a purchase agreement. The same filing registered resale of up to 3 million ordinary shares and warned that future share sales may dilute current holders and drag the stock price.
Friday’s open is set to show if the premarket gains last as normal trading picks up. Moves in extended hours are quick, but liquidity is usually lower and spreads can widen. Public’s premarket page for PRFX flagged that execution and liquidity might not match regular hours.
