SNT Energy recorded a double-digit gain in the regular session on the 26th and is extending its increase in the NXT (NexTrade) after-market as well.

■ 15.33% Surge in Regular Session… Rose to 33,300 Won Intraday

In the Korea Exchange (KRX) regular session on the 26th, SNT Energy finished trading at 32,350 won, up 4,300 won (15.33%) from the previous trading day. The stock, which opened at 29,550 won, rose to as high as 33,300 won during the session, showing strong momentum. Trading volume in the regular session totaled 854,712 shares, with trading value recorded at approximately 27.16 billion won.

■ Gains Continue in NXT After-Market… Price Distinction Needed

Buying interest has continued even after the regular session closed. Around 5 p.m. in the NXT after-market, SNT Energy was trading at 34,150 won, up 6,100 won (21.75%) from the previous day's close of 28,050 won. It rose as high as 34,700 won during the session, forming a price level higher than the regular session's closing price.

With consecutive gains in both the regular session and the after-market, short-term trading enthusiasm has risen significantly. However, as the regular session closing price and the NXT after-market price involve different trading venues and trading hours, they need to be viewed separately.

■ Overseas Plant Business and Earnings Improvement Cited as Evaluation Factors

SNT Energy is a company that designs and manufactures air-cooled heat exchangers used in oil, gas, and petrochemical plants, as well as heat recovery steam generators (HRSG), condensers, and nitrogen oxide reduction devices. The company has pursued overseas business expansion through securing HRSG source technology, establishing a U.S. subsidiary, and localization in Saudi Arabia.

Its earnings announced early this year have also been cited in the market as an evaluation factor. SNT Energy announced that it recorded consolidated revenue of 606.1 billion won and operating profit of 111.3 billion won for 2025, and the stock surged more than 20% intraday following that earnings announcement.

■ Surge Causes and Risks Should Be Checked Together

However, the direct cause of the sharp rise in NXT on this day needs to be verified alongside any additional disclosures or official company announcements. The after-market may have different trading volume and liquidity conditions from the regular session, so there is a possibility that price volatility could widen.

[The stock market can experience greatly expanded price volatility depending not only on corporate earnings, orders, disclosures, and industry conditions, but also on market supply and demand. In particular, stocks that have surged sharply in a short period may see their gains shrink quickly, so it is necessary to check regular session and NXT prices separately.
