Mplus recorded 328 percent growth in first-quarter operating profit as it expanded sales of overseas prismatic battery equipment and energy storage system equipment. The company said on May 15 it posted first-quarter consolidated revenue of 51.0 billion won and operating profit of 10.2 billion won in 2026. Revenue rose 120 percent from a year earlier and operating profit gained 328 percent. The operating margin reached 20 percent.

The main driver of the results was expanded sales of prismatic battery assembly equipment for overseas markets and equipment for ESS (energy storage systems). The company said demand flowed in as the ESS market grows rapidly on accelerating global energy transition and rising power demand from AI (artificial intelligence) data centers.

On the product side, high value-added products such as prismatic form-factor assembly equipment and ultra-high-speed notching equipment led performance. Profitability indicators also improved. The operating margin rose to 20 percent, nearly doubling from 10.3 percent a year earlier. The company said it established a profitability-focused management stance with a full-year operating margin of 13.3 percent last year, and that the trend continues in the first quarter of 2026.

Mplus has manufacturing technology for equipment covering the entire assembly process for secondary batteries across all form factors, including pouch, prismatic and solid-state. The company said it has also secured an electrode process equipment lineup, establishing a full-process turnkey response system for solid-state battery production.

The company views the quarter as a turning point for expanding its global business base. A Mplus official said the company plans to build out a solid-state battery assembly equipment line to meet new demand such as robot batteries and UAV (unmanned aerial vehicle) batteries targeting the era of physical AI.
