On April 20, 2026, the South Korean solar industry found itself at a crossroads, with OCI Holdings and Hanwha Solutions — two giants in the sector — charting dramatically different courses. The day’s trading numbers and a swirl of international developments painted a vivid picture of shifting fortunes, growing global competition, and the high stakes riding on strategic moves in solar supply chains.
OCI Holdings, long regarded as a bellwether for Korea’s solar ambitions, ended the day with its stock price closing at 273,000 KRW, up 2.05% from the previous session’s 267,500 KRW, according to TopStarNews and KRX data. The company’s shares opened at 275,000 KRW, swung between a low of 257,500 KRW and a high of 292,500 KRW, and saw a robust trading volume of 631,165 shares, with a total trading value of approximately 174.56 billion KRW. This surge reflected a market capitalization of about 5.097 trillion KRW, ranking OCI Holdings 123rd on the KOSPI, with foreign investors holding 19.05% of outstanding shares and a dividend yield of 0.37%.
But the numbers only tell part of the story. According to SisajournalE, OCI Holdings was expected to post a disappointing first-quarter operating profit — a sharp drop to 12.5 billion KRW, down over 70% from 48.7 billion KRW in the same period last year. The culprit? Early and extended maintenance at its Malaysian subsidiary, OCI Terrasus, which slashed the polysilicon plant’s operating rate to 50% in Q1, compared to a brisk 90% at the end of 2025. This operational hiccup weighed on immediate results, but analysts and industry insiders were quick to describe it as a temporary setback.
"The first quarter’s performance is the low point for the year," Kyobo Securities analyst Jo Hye-bin wrote in a recent report. "From the second quarter, with Terrasus’s operations normalized and the profit from the sale of the OCI Energy 500MW project reflected, quarterly results will improve." Jo added that the pace of profit growth would accelerate in the second half of 2026, especially as Neosilicontech — acquired by OCI Terrasus earlier in the year — ramps up wafer shipments and U.S. Section 232 trade policies potentially drive up average selling prices.
Despite the Q1 dip, the consensus for OCI Holdings’s annual operating profit stood at a healthy 420 billion KRW, signaling optimism for a clear turnaround. Much of this confidence hinges on the evolving U.S. stance toward solar supply chains. As the United States restricts subsidies for solar materials sourced from so-called "prohibited foreign entities" (read: China), demand for non-China polysilicon has surged. OCI Terrasus, with its Malaysian production base, is perfectly positioned to benefit from this geopolitical shift.
Further fueling investor enthusiasm, news broke on April 15 that OCI Terrasus was in talks with SpaceX — Elon Musk’s famed aerospace company — regarding a long-term polysilicon supply contract for solar applications. According to ZDNet Korea, this revelation sent OCI Holdings’s stock price soaring, even as profit-taking led to some volatility in subsequent sessions. The prospect of becoming a key supplier to SpaceX, coupled with Tesla’s formal request to the U.S. Commerce Department to include allies like South Korea in the American solar supply chain, has only strengthened the company’s outlook.
Chairman Lee Woo-hyun of OCI Holdings spoke to the company’s strategy during an April 20 conference call, stating, "Even in a year of growing business uncertainty, OCI Holdings has made strategic investments to build a non-PFE (prohibited foreign entity) solar value chain, from Malaysian polysilicon to Vietnamese wafers. Moving forward, we’ll focus on high-growth, high-value sectors like power infrastructure and semiconductor materials, in step with the AI era, to enhance shareholder value."
OCI Terrasus’s acquisition of Neosilicontech earlier in 2026 has shored up the company’s value chain, securing a wafer production capacity of 5.4GW — and more expansion is reportedly in the pipeline. This integration is expected to further boost OCI Holdings’s earnings and solidify its status as a linchpin in the global non-China solar supply network.
Meanwhile, Hanwha Solutions, once a peer rival in the solar race, found itself on shakier ground. On April 20, its stock price fell 2.27% to 43,050 KRW, continuing a recent trend of underperformance. The company’s woes can be traced to a large-scale rights offering announced earlier in the year. Initially set at 2.4 trillion KRW, the offering was scaled back to 1.8144 trillion KRW on April 17 after a sharp shareholder backlash, with the portion earmarked for debt repayment also reduced. Still, concerns about shareholder dilution, increased interest burdens, and the potential for further capital raises have weighed heavily on the stock.
Shareholder discontent has spilled into the courts, with Hanwha Solutions’s minority shareholders filing lawsuits against two newly appointed outside directors, alleging breaches of fiduciary duty in connection with the rights offering. According to ZDNet Korea, the company has defended its process, saying, "All directors received the same level of information and participated in thorough discussions before making reasonable business decisions. Even if the two new directors opposed the rights offering, the outcome would not have changed, as the rest of the board supported it."
Despite these internal challenges, Hanwha Solutions’s long-term prospects are not without hope. The company still stands to benefit from U.S. solar tax credits and, perhaps more importantly, from China’s recent moves to restrict exports of solar equipment to the U.S. and other markets. Hwang Sung-hyun, an analyst at Eugene Investment & Securities, noted, "China has begun considering export restrictions on U.S.-bound solar equipment, and the value of non-China solar supply chains is expected to increase. Although recent announcements have heightened stock volatility, Hanwha Solutions is likely to be re-evaluated as a high-efficiency, non-China solar supplier."
Yet, as of now, the market’s verdict is clear: OCI Holdings is riding a wave of international opportunity and strategic investments, while Hanwha Solutions is grappling with shareholder unrest and lingering doubts about its capital structure. The solar sector’s future, it seems, will turn not just on technological advances or government policy, but on the ability of companies to navigate the complex interplay of global supply chains, investor expectations, and shifting political winds.
For OCI Holdings, the coming quarters offer a chance to prove that its recent stumbles were only temporary — and that its bets on non-China supply, value chain integration, and partnerships with industry leaders like SpaceX are about to pay off in a big way.
