LG Innotek posts record Q3 sales, but profit misses forecasts

LG Innotek grew sales strongly in the third quarter, but earned much less from those sales. Revenue increased 18.6% year over year to 6.37 trillion won, the company’s highest third-quarter figure. Operating profit fell 53.4% to 94.8 billion won.

The contrast shows why sales growth does not always produce higher profits. Optical solutions, mainly smartphone camera modules, generated 5.40 trillion won, helped by new smartphone production and more automotive camera shipments. However, higher material costs reduced the benefit of that demand.

LG Innotek blamed the gap partly on the won-dollar exchange rate. It bought materials when the dollar was stronger, then shipped products after the won strengthened. Analysts expect pressure to ease in the fourth quarter as lower-exchange-rate materials enter production. Longer term, semiconductor substrates could broaden its earnings base.

The earnings miss was substantial. Analysts surveyed by FnGuide expected operating profit of 197.3 billion won, but LG Innotek reported only 94.8 billion won. The gap was 102.5 billion won, meaning actual profit was roughly 52% below the forecast.

The margin decline gives another view of the pressure. Operating margin measures operating profit as a share of revenue. It dropped from 3.8% a year earlier to 1.5% in the latest quarter. That is a fall of 2.3 percentage points, even though revenue reached a record third-quarter level.

Higher material costs and currency movements explain much of the deterioration. Materials purchased with a stronger dollar became costly compared with later sales made after the won strengthened. The company expects some relief in the fourth quarter as cheaper materials enter production.

Operating profit shows how much a company earns from its core business after costs such as materials, manufacturing, wages, and other operating expenses. It excludes financing and tax effects, so it helps reveal whether the underlying business is profitable.

Operating margin expresses that profit as a percentage of sales. The formula is operating profit divided by revenue, multiplied by 100. For LG Innotek, 94.8 billion won of operating profit divided by 6.37 trillion won of revenue produces an operating margin of about 1.5%.

This measure matters because it separates growth from efficiency. LG Innotek’s revenue rose 18.6%, but its margin fell from 3.8% to 1.5%. The company therefore sold more while keeping less profit from each won of sales, mainly because material costs rose and currency movements hurt results.

The currency problem came from a timing mismatch. LG Innotek purchased raw materials at one exchange rate and shipped finished products later at another. The company said the won-dollar exchange rate declined sharply between those two events.

In practical terms, materials bought when the dollar was stronger required more won. When the won later strengthened, the same dollar-linked costs became relatively larger compared with the won revenue recorded from product shipments. Costs therefore rose faster than the sales value used to measure profit.

This squeezed operating profit even while demand remained strong. Optical-solutions sales increased 20.6% to 5.40 trillion won, but companywide operating profit fell to 94.8 billion won. LG Innotek expects pressure to ease in the fourth quarter because materials purchased at lower exchange rates will begin entering production.

LG Innotek remains heavily tied to camera-related business. Its optical-solutions division produced 5.40 trillion won in the quarter, or nearly 85% of total revenue. The division includes smartphone camera modules and also benefited from rising automotive camera shipments to a North American customer.

That concentration matters because camera earnings can be affected by smartphone production cycles, customer demand, material prices, and manufacturing costs. In this quarter, camera demand was strong, yet higher material costs and currency effects still cut operating profit by more than half. Strong sales alone did not protect profitability.

The company is trying to reduce this dependence. It plans AI-assisted automation, in-house production of key camera components, and more diverse production sites to lower costs. It is also developing semiconductor substrates, with entry into more complex AI and server products planned in stages through 2028.

A semiconductor substrate is a thin packaging base that supports a chip and provides connections between the chip and a larger circuit board. It helps package the processor so electrical signals and power can move between the chip and the system. FC-BGA means flip-chip ball grid array, a substrate format used with advanced processor packages.

LG Innotek’s package-solutions business sells these products. Its revenue rose 10.1% to 481.8 billion won, helped by high-value substrates and increased FC-BGA shipments for PC processors. The article identifies substrates for AI accelerators and servers as more complex products the company plans to enter.

This business is still small, contributing 7.6% of total sales. LG Innotek plans a staged market entry through 2028, alongside factory expansion and possible investment in South Korea and overseas. The move could make substrates more important to future growth.

Expanding semiconductor-substrate sales could diversify LG Innotek’s revenue. Today, nearly 85% of sales come from optical solutions dominated by smartphone camera modules. A larger package-solutions business would give the company another source of sales and profit.

The mechanism is straightforward. Smartphone-camera results depend heavily on new phone production, camera manufacturing costs, materials, and customer orders. Substrates serve other products, including PC processors and, eventually, AI accelerators and servers. Different end markets could reduce the company’s reliance on one product category.

The shift will take time. Package solutions currently generate only 7.6% of sales, although revenue rose 10.1% to 481.8 billion won. LG Innotek plans to enter more complex substrate markets in stages through 2028, while expanding factories and considering further investment. Analysts describe this expansion as critical to reducing camera dependence.
