Soulbrain Eyes Q3 Margin Rebound, ₩5 Billion Initial Volume

Key Takeaways

Soulbrain supplies chemicals used in semiconductor manufacturing. From the third quarter, the key issue is not revenue but how quickly normalized selling prices translate into operating profit.

Shinhan Securities said customer pricing negotiations concluded in the second quarter, making a profitability recovery increasingly likely in the third quarter. Initial acetic acid-based volume is estimated at 5 billion won per quarter, while glass substrates are slated for a third-quarter pilot and fourth-quarter sample supply.

What Happened

On the 1st, Shinhan Securities named Soulbrain its top pick in the materials industry sector. The core rationale is straightforward: in a structure where costs rise first and customer prices are adjusted later, margins recover faster than shipment volumes once pricing negotiations conclude.

The report said pricing discussions continued through the second quarter but normalization could begin in the third quarter. In the second half, acetic acid-based revenue is expected to increase gradually alongside non-memory customers’ production plans, while the market has already priced in much of the near-term profitability weakness.

Glass-substrate investment provides another potential catalyst. The roadmap calls for technical reviews and pilot-line investment in the second quarter, production-line construction in the third quarter, and a sample-supply system in the fourth quarter. For now, its option value outweighs its revenue contribution.

Background and Context

Unlike semiconductor equipment stocks, materials suppliers feel the impact of orders later, primarily through fab utilization rates. Consumption of etchants and cleaning solutions rises only when wafers actually begin running through new DRAM fabs, converted NAND lines, or new U.S. foundry fabs. Investors assessing Soulbrain should therefore consider utilization rates and ramp-up speeds alongside customer capex.

A key strength of the report is that it does not discuss an industry recovery only in abstract terms. By specifying figures and milestones—including 5 billion won in initial volume, a third-quarter pilot, and fourth-quarter samples—it allows investors to distinguish expectations that the share price may discount early from contributions that ultimately flow into earnings.

Why Improvement Is Expected From the Third Quarter

Once selling-price adjustments are completed, cost pressure begins to ease. Because materials suppliers’ profits are more sensitive to margins than volumes, the scale of the operating-margin recovery will matter more than revenue growth in third-quarter earnings.

Conversely, delayed customer capacity expansions would also push back the recovery. If DRAM and NAND utilization rates rise less than expected or new lines such as the Taylor fab are delayed, growth in acetic acid-based and high-value-added materials could slow. Margin recovery can continue if customer utilization rates hold up, but the rebound will lose momentum if ramp-ups weaken.

Impact on the Market and Stocks

• Soulbrain: Normalized selling prices and a larger share of high-value-added materials have increased the likelihood of an earnings-capacity recovery from the third quarter.
• Dongjin Semichem: As the markets for etchants and cleaning solutions tend to move together, the company is also positioned to benefit from recovering semiconductor-fab utilization rates.
• Samsung Electronics and SK hynix: As customers expand capacity and migrate to more advanced technologies, greater materials consumption increases revenue leverage for suppliers such as Soulbrain.
• Glass-substrate stocks: With the business still at the sample and pilot stages, valuations depend more on whether companies secure positions in the supply chain than on earnings.
• Materials industry sector overall: The gap may widen between companies that can pass through costs and those that cannot, resulting in divergent rates of margin recovery even among semiconductor-materials suppliers.

Investor Checklist

• Confirm whether the operating margin actually improves when third-quarter earnings are released.
• Monitor whether acetic acid-based revenue is sustained at 5 billion won per quarter or whether the initial volume proves to be a one-off.
• For glass substrates, the key milestone is whether the fourth-quarter sample-supply system is established as planned.
• Expectations could be pushed back if ramp-ups at new DRAM fabs and U.S. foundry fabs are delayed.

Outlook

The bullish scenario is clear. If selling prices stabilize following the completion of pricing negotiations, customer utilization rates rise, and acetic acid-based products and glass substrates sequentially open the next phase of earnings growth, Soulbrain could regain a premium valuation within the materials industry sector.

Risks remain. Glass substrates are still at the pilot and sample stages, leaving commercialization delays as a concern, while a slower memory-investment cycle would postpone shipment growth for high-value-added materials. For this stock, confirmation matters more than expectations.

Frequently Asked Questions

Why Is Soulbrain’s Profitability Expected to Improve From the Third Quarter?

The key is pricing negotiations. Because costs rose before customer selling prices followed, margins should recover faster than revenue once negotiations with customers are completed. The third quarter is expected to be when that normalization becomes visible in the numbers.

Will the Glass-Substrate Business Contribute to Earnings Immediately?

Not yet. The sequence calls for technical reviews and a pilot in the second quarter, production-line construction in the third quarter, and sample supply in the fourth quarter. For now, it represents option value rather than an immediate profit contribution. The timing of actual revenue recognition will depend on the pace of customer adoption.

What Indicators Would Confirm the Trend?

The third-quarter operating margin, acetic acid-based volume, and glass-substrate sample schedule are the most important indicators. If DRAM and NAND utilization rates also rise, increased materials consumption would reinforce confidence in the recovery.
