Tosoh posted increases in both revenue and earnings in Q1, with the operating margin expanding significantly due to a recovery in chemical product market conditions and an improved product mix. Revenue was ¥2,741.7B (+11.8% YoY), Operating Income was ¥311.8B (+93.9%), Ordinary Income was ¥343.0B (+143.6%), and consolidated Net Income was ¥219.8B (+148.4%). Revenue growth was driven by expansion across all segments, including Basic Materials, Value-Added Materials, and Water Treatment. The primary drivers of earnings growth were the turnaround to profitability in the Basic Materials segment, which had reported an operating loss in the previous year, and expansion in the high-margin Value-Added Materials and Bioscience businesses.
【Revenue】All segments recorded higher revenue, resulting in broad-based top-line growth. Based on sales to external customers, Basic Materials was the largest segment at ¥1,248.3B (45.5% of total, +13.4% YoY), followed by Value-Added Materials at ¥428.6B (+13.9%) and Water Treatment Engineering at ¥419.8B (+9.5%). Bioscience was nearly flat at ¥154.4B (+0.2%), with slower growth than the other segments.
【Profit and Loss】Operating Income increased +93.9% to ¥311.8B. The gross margin improved by +4.1pt to 27.2% (23.1% in the previous year), while the operating margin improved by +4.8pt to 11.4% (6.6% in the previous year). The largest positive factor was the turnaround in Basic Materials’ operating results, from an operating loss of △¥33.9B in the previous year to profit of ¥56.6B in the current period. Value-Added Materials posted Operating Income of ¥82.0B (+109.1%), representing the largest contribution to segment earnings at 26.3% of total segment profit. Bioscience maintained high profitability, with a margin of 36.6%. Meanwhile, Water Treatment Engineering recorded lower earnings despite higher revenue, with Operating Income of ¥65.5B (-8.7%) and its margin declining from 18.7% to 15.5%, suggesting an impact from project mix. Ordinary Income grew faster than Operating Income, supported by non-operating income including foreign exchange gains of ¥16.6B and dividend income of ¥8.9B. Consolidated Net Income increased +148.4% despite absorbing extraordinary losses of ¥11.5B, primarily losses on disposal of fixed assets of ¥11.2B, leading to the conclusion that the company achieved both revenue and earnings growth.
The composition of segment profit (totaling ¥311.8B) was as follows: Value-Added Materials at ¥82.0B (26.3% of total, YoY+109.1%), Water Treatment Engineering at ¥65.5B (21.0%, YoY-8.7%), Bioscience at ¥57.4B (18.4%, YoY+24.0%), Basic Materials at ¥56.6B (18.2%, a turnaround from an operating loss in the previous year), High-Performance Materials at ¥31.7B (10.2%, YoY+29.1%), and Other at ¥18.6B (6.0%, YoY+45.2%).
Basic Materials made the largest contribution to earnings growth, as the segment turned profitable on higher revenue of +13.4% and improved profitability. Value-Added Materials and Bioscience are relatively high-margin businesses, with margins of 15.8% and 36.6%, respectively, and drove earnings growth. Water Treatment Engineering was the only segment to report lower earnings. The decline in its margin from 18.7% to 15.5% despite higher revenue suggests variability in project profitability, which will be subject to monitoring going forward.
【Profitability】The operating margin improved by +4.8pt to 11.4% from 6.6% in the previous year. The gross margin also expanded by +4.1pt to 27.2% from 23.1%, while the consolidated net profit margin improved by +4.4pt to 8.0% from 3.6%. ROE was 2.4% (quarterly, non-annualized), exceeding 0.96% in the previous year, indicating that the recovery in profitability is being reflected in return metrics.【Cash Flow Quality】Operating Cash Flow (OCF) remained at only ¥3.6B, representing just 0.02x consolidated Net Income of ¥219.8B, an exceptionally low level that indicates a delay in cash conversion.【Investment Efficiency】Although the total asset turnover ratio improved slightly to 0.187x from 0.174x in the previous year, it remained low. ROA, based on consolidated Net Income, increased to 1.50% from 0.63%.【Financial Soundness】The Equity Ratio was 63.2%, down -2.0pt from 65.2% in the previous year. Short-term borrowings increased to ¥1,861.2B (+28.6% YoY), while the current ratio remained strong at 213%, indicating ample short-term liquidity.
Cash flow from operating activities was ¥3.6B, a substantial decline of -99.0% from ¥365.1B in the previous year. Working capital was the primary factor: an increase in inventories resulted in a cash outflow of ¥107.2B, while an increase in trade receivables resulted in a cash outflow of ¥131.4B. Income taxes paid of ¥167.6B also weighed on cash flow. Cash flow from investing activities was -¥199.6B, reflecting continued investment in property, plant and equipment. Free Cash Flow was -¥196.0B (OCF of ¥3.6B + investing cash flow of -¥199.6B). Cash flow from financing activities was +¥315.6B, primarily supplementing funding requirements through additional short-term borrowings. Whether the accumulation of inventories and accounts receivable accompanying revenue growth is temporary or structural will depend on the degree of normalization observed in subsequent quarters.
The gap between Ordinary Income of ¥343.0B and consolidated Net Income of ¥219.8B reflects income taxes of ¥112.0B and Net Income attributable to non-controlling interests of ¥25.2B. The impact of extraordinary gains and losses—extraordinary gains of ¥0.2B and extraordinary losses of ¥11.5B—was limited. Of non-operating income of ¥46.8B, foreign exchange gains of ¥16.6B are dependent on market fluctuations, while dividend income of ¥8.9B represents relatively stable earnings. Comprehensive Income of ¥276.8B exceeded consolidated Net Income of ¥219.8B by ¥57.0B. The primary factors behind this difference were valuation differences on securities of +¥40.7B, foreign currency translation adjustments of +¥14.7B, and equity-method OCI of +¥8.8B, reflecting changes in asset values exceeding the earnings power of the underlying business. Meanwhile, OCF was extremely low relative to Net Income at ¥3.6B. The fact that accrual-related factors, namely increases in inventories and accounts receivable, delayed the conversion of earnings into cash is an important consideration in assessing earnings quality.
The Q1 progress rates against the company’s full-year forecast—Revenue of ¥11,700.0B, Operating Income of ¥1,050.0B, and Ordinary Income of ¥1,070.0B—were 23.4%, 29.7%, and 32.1%, respectively. All profit metrics were progressing at a pace above the simple 25% benchmark. Progress against the full-year forecast for Net Income attributable to shareholders of the parent company of ¥590.0B was also ahead at 33.0%, indicating that earnings were progressing above plan as of Q1. The company revised its earnings forecast during the quarter, while no revision was made to its dividend forecast.
The company’s full-year dividend forecast is ¥100 per share, double the ¥50 full-year dividend forecast as of the same period of the previous year. The Payout Ratio against forecast EPS of ¥191.63 is approximately 52.2%, representing a dividend increase plan accompanied by earnings growth. Meanwhile, Q1 Free Cash Flow was -¥196.0B and actual dividend payments were ¥154.1B. The dividend for the current period was not fully covered by internally generated funds, with funding through increased short-term borrowings serving as the effective source of funds. Given that full-year Operating Income is progressing above plan, the outlook for securing funds for dividends as of the fiscal year-end appears relatively favorable.
Cash Conversion Risk: OCF was ¥3.6B, representing only 0.02x Net Income of ¥219.8B, an extremely low level. The primary factors were increases of +¥107.2B in inventories and +¥131.4B in trade receivables. If this situation continues, the deficit in Free Cash Flow could become structural.
Variability in Segment Profitability: Water Treatment Engineering recorded lower Operating Income of -8.7% despite higher revenue (+10.5%), with its margin declining from 18.7% to 15.5%. Basic Materials’ margin was also 3.9%, below the company-wide average of 11.4%, indicating earnings disparities within the portfolio.
Dependence on Short-Term Funding: Short-term borrowings increased to ¥1,861.2B (+28.6% YoY), and cash flow from financing activities was +¥315.6B. The company is covering the shortfall in Free Cash Flow and dividend payments through additional short-term liabilities, indicating a shortening of its funding structure.

The turnaround to operating profitability in the Basic Materials segment was the primary driver of earnings growth, with the segment moving from an operating loss of △¥33.9B in the previous year to profit of ¥56.6B in the current period. Whether this turnaround reflects temporary cost and market condition factors or structural profitability improvements will be determined by the segment’s margin trends in subsequent quarters.
Value-Added Materials (15.8% margin) and Bioscience (36.6% margin) are high-margin segments that lifted the company-wide margin. Changes in the sales mix of these high-value-added areas will determine future margin levels.
The exceptionally low level of OCF relative to Net Income (0.02x) resulted from working capital factors, namely increases in inventories and accounts receivable. Whether these increases are temporary accumulations accompanying revenue growth or reflect a structural change in capital efficiency can be assessed through future trends in inventory and receivables turnover metrics.
