Sajo Oyang continues to grow revenue, but quarterly earnings show wide swings while affiliate ownership concentration keeps deepening.
2025 revenue rose to KRW 417.4bn year over year, but operating margin fell from 5.2% to 3.2%
Recent quarters show sharp swings, with operating profit dropping to about KRW 0.2bn in 2025Q4 and KRW 0.48bn in 2026Q2
Affiliate share purchases led by controlling shareholder Sajo Daerim have continued for years, raising combined insider ownership
At the 2025 shareholder meeting, the outside director nominated by minority shareholders was not reappointed, weakening minority representation on the board
The deep-sea fishing segment faces structural pressure from declining tuna catches, tighter resource conservation rules, and rising competing vessels
Sajo Oyang was established in 1969 as a company engaged in both food processing and deep-sea fishing, joined the Sajo Group in 2007, and expanded its food processing business through a 2015 merger with Sajo Nambu Ham.
Its operations are broadly divided into a food manufacturing segment, a deep-sea fishing segment, and a leasing segment.
The food manufacturing segment produces fish-paste products such as crab-flavored surimi sticks and sausages at factories in Geumsan, Pyeongtaek, Yangsan, and Imsil, operating under HACCP and FSSC 22000 quality certifications.
The deep-sea fishing segment centers on tuna longline and purse-seine fishing, with operations continuing in areas including the Indian Ocean.
On the governance side, controlling shareholder Sajo Daerim holds the largest stake, while a group of affiliates including Sajo Industries, Sajo Seafood, Sajo Dongah One, Sajo America, and Castlex Seoul each hold smaller stakes.
This reflects part of the Sajo Group's effort to build a vertically integrated structure spanning catch (Sajo Industries), processing (Sajo Daerim and Sajo Oyang), and distribution/food service (Foodist).
In the domestic processed seafood market, the company competes against a number of large food manufacturers, and it is pursuing competitiveness through new product development, automation investment, and cost reduction.

Annual revenue grew for four consecutive years, from KRW 369.1bn in 2022 to KRW 391.5bn in 2023, KRW 400.7bn in 2024, and KRW 417.4bn in 2025.
Operating profit, however, improved from KRW 10.2bn in 2022 to KRW 16.3bn in 2023 and KRW 20.9bn in 2024 before declining to KRW 13.5bn in 2025, with the operating margin falling from 5.2% in 2024 to 3.2% in 2025.
Net income showed a divergent pattern in 2023, reaching KRW 20.3bn, well above that year's operating profit of KRW 16.3bn, suggesting a meaningful non-operating contribution, before falling to KRW 12.6bn in 2024 and KRW 10.6bn in 2025.
Recent quarterly results show pronounced swings: operating profit fell from KRW 5.91bn in 2025Q2 to KRW 3.65bn in Q3 and just KRW 0.21bn in Q4, rebounded to KRW 6.95bn in 2026Q1, then dropped again to KRW 0.48bn in 2026Q2.
Net income also fluctuated sharply across the same quarters, from KRW 7.06bn to KRW 1.47bn, KRW 1.80bn, KRW 4.70bn, and KRW 2.15bn, respectively. This volatility likely reflects the combined effects of catch volumes and prices in the fishing segment, raw material market conditions, and non-operating items.
The pattern of margin compression despite revenue growth appears to track a broader rise in cost burdens across the food industry.
The domestic food industry broadly experienced margin compression from rising raw material costs, a higher exchange rate, and increased fixed-cost burdens.
The revenue-weighted average cost-of-sales ratio among major food companies rose from 74.3% in 2024 to 75.2% in 2025, and Sajo Oyang recorded the highest cost-of-sales ratio among the surveyed major food companies at 89.6%, reflecting the company's high exposure to raw material price swings given its seafood- and meat-processing-heavy business mix.
In the deep-sea fishing segment, declining tuna purse-seine catch volumes were partly offset by higher fish prices, but structural pressures from tightening international resource conservation regulations and a growing number of competing vessels have persisted.
The food manufacturing segment is responding through new product development and quality improvements, though weaker consumer sentiment amid an economic slowdown is cited as a headwind.
At the group level, Sajo Group was designated for the first time last year as a business group subject to disclosure requirements by the Fair Trade Commission (assets above KRW 5 trillion), reaching large-conglomerate status, a process that also strengthened its vertically integrated structure spanning catch, processing, and distribution through acquisitions of food ingredient distributors.
In terms of competitive positioning, affiliate Sajo Daerim and other large food manufacturers continue to compete alongside the company in the processed seafood market.
The company states that its food manufacturing segment is responding to weaker consumer sentiment amid an economic slowdown and raw material price volatility through new product development and quality improvements.
The deep-sea fishing segment continues to supplement earnings through higher fish prices even as it navigates tighter resource conservation rules and a growing number of competing vessels.
On the governance front, Sajo Group affiliates have continued purchasing shares in Sajo Oyang over recent years, and whether this pattern continues, along with the direction of any broader group governance restructuring, remains a point to watch.
At the group level, having strengthened vertical integration through acquisitions of food ingredient distributors and starch/sugar manufacturers, market attention to the scale of intercompany transactions and related regulatory issues is likely to continue.
No specific quantified earnings guidance or large-scale capacity expansion or order plans have been identified in currently available disclosures.
Given that a year-end dividend was resolved for fiscal 2025, the continuity of dividend policy going forward is also a point worth monitoring from a shareholder return perspective.
The current share price trades at a discount to net asset value, with the price-to-book ratio below 1x — a factual relationship distinct from any value judgment.
The price-to-earnings ratio, based on the trailing four quarters of results, sits in the high single digits, a level that appears to reflect the business's considerable quarter-to-quarter earnings volatility.
A cash dividend was resolved as part of the fiscal 2025 settlement, and the resulting dividend yield level will vary over time along with the share price.
The structural feature of affiliates and the owner family holding most of the shares, leaving a low free float, is also a factor worth considering alongside trading and valuation dynamics.

Revenue grew for four consecutive years from 2022 through 2025, expanding from KRW 369.1bn to KRW 417.4bn. This appears to reflect a combination of new product development in the food manufacturing segment and higher fish prices in the deep-sea fishing segment. Sustained top-line growth points to a degree of stability in the underlying business base.
The Sajo Group has built a vertically integrated structure spanning catch (Sajo Industries), processing (Sajo Daerim and Sajo Oyang), and distribution (Foodist). This structure offers potential synergies in raw material procurement and securing sales channels across affiliates.
The fact that the group was designated as a large business group for the first time last year reflects the scale achieved through this structure.
Operating profit in 2026Q1 recovered sharply to KRW 6.95bn from just KRW 0.21bn in the preceding quarter, 2025Q4. This may reflect seasonal demand factors such as holiday gift-set sales. A recurring seasonal rebound pattern would suggest room for improvement in specific quarters.
Operating profit shrank sharply relative to revenue scale in repeated quarters, falling to KRW 0.21bn in 2025Q4 and KRW 0.48bn in 2026Q2. Such swings can reduce the predictability of results. The gap between quarters appears wide, driven by a combination of cost structure and non-operating items.
Sajo Oyang's 2025 cost-of-sales ratio of 89.6% was the highest among 22 major food companies surveyed. This reflects high sensitivity to raw material prices and exchange rate movements given a business mix weighted toward seafood and meat processing. Continued cost pressure could constrain operating margin improvement.
Share purchases by controlling shareholder Sajo Daerim and other affiliates have continued, steadily raising the combined stake of the controlling shareholder and related parties over several years.
At the 2025 shareholder meeting, the outside director nominated by minority shareholders was not reappointed, weakening minority representation on the board. This ownership structure, combined with a shrinking free float, can raise governance-related concerns.
Prices of imported raw materials such as surimi and palm oil, along with exchange rate movements, directly affect Sajo Oyang's cost structure.
Given its industry-leading cost-of-sales ratio, continued raw material price increases or a weaker won could intensify margin pressure, while stabilizing input costs or a stronger won could support margin improvement.
The tuna purse-seine business faces structural pressure from declining catch volumes, tightening international resource conservation regulations, and a growing number of competing vessels. This can continue to affect the revenue and profitability of the deep-sea fishing segment. Rising fish prices have partly offset this, but the burden could grow if regulations tighten further.
The structure in which the combined stake of the controlling shareholder and related parties has steadily risen through continued affiliate share purchases carries potential controversy related to minority shareholder rights and board representation. A shrinking free float can also affect trading liquidity.
Regulatory issues related to intercompany transactions following the group's designation as a large business group by the Fair Trade Commission also warrant continued attention.
The 2026 Q3 quarterly report disclosure should be checked to see whether operating margin recovers and how the cost-of-sales ratio trends.
Large shareholding report disclosures related to any further affiliate share purchases in Sajo Oyang can be monitored for governance changes.
The fiscal year 58 dividend decision and board composition agenda items can be checked for shareholder return policy and minority representation.
The Fair Trade Commission's large business group designation results should be checked to see whether Sajo Group's controlling person is designated and how intercompany transaction regulations would apply.
Sajo Oyang has delivered four straight years of revenue growth, but its 2025 operating margin fell to 3.2% and quarterly earnings swings widened, presenting a mixed picture on earnings stability.
The deep-sea fishing segment faces structural pressure from resource conservation regulations and declining catch volumes, while the food manufacturing segment carries an industry-leading cost-of-sales burden.
At the same time, revenue expansion, new product responses, and supply-chain stability from group vertical integration stand as coexisting positive factors.
On governance, continued affiliate share purchases have raised the combined stake of the controlling shareholder and related parties while weakening minority representation on the board, a factor that should be weighed alongside the operational picture.
Going forward, margin recovery in coming quarters, changes in the ownership structure, and group-level regulatory issues are all points worth continued observation. This report contains no investment opinion or buy/sell recommendation and is provided for informational purposes only.
