Korea Gas Corp: September Preliminary Filing Shows Volumes Only, No Earnings Figures

Why this report

Written after:

Korea Gas Corporation's 2026-10-13 preliminary earnings filing left the revenue, operating income and net income fields blank and disclosed only September gas sales volumes. It does not change the earnings picture from our initiation, and our model fair value range is unchanged in structure from the data given.

What happened

On 2026-10-13 the company filed a fair-disclosure preliminary earnings notice for September 2026 (the period 2026-09-01 to 2026-09-30), with year-to-date figures covering 2026-01-01 to 2026-09-30. In the filing excerpt, every financial line (revenue, operating income, pre-tax income from continuing operations, net income) shows a dash, so no profit or sales figures were disclosed. Only the gas volume table is filled in.

September volumes totaled 1,764 thousand tons, against 2,116 thousand tons in August. The excerpt does not show the year-earlier total or the change from it, as the text is cut off. City gas volumes were 955 thousand tons, up 0.6% from August and up 4.8% from September 2025 (911 thousand tons). Power generation volumes were 809 thousand tons, down 30.7% from August (1,167 thousand tons) and down 19.7% from September 2025 (1,007 thousand tons). The excerpt shows no figure for the other category.

What it changes for the thesis

Our initiation described improving earnings (trailing operating margin of 7.1% versus 5.9% in 2025) set against falling revenue, high leverage (liabilities 345.3% of equity) and uneven results. This filing offers no new profit data, so it neither confirms nor challenges that picture.

The volume mix is a small, partial signal. Residential and commercial city gas demand grew year on year, while power generation volumes fell sharply. The data pack does not tell us how these volumes translate into margins, so we draw no earnings conclusion. The leverage and earnings-volatility concerns from the initiation are unchanged.

What it changes for the valuation

The initiation had no stated fair value (previous_report.fair_value is null), so there is no prior range to compare. Our model fair value range now is ₩326,395 (bear), ₩406,296 (base) and ₩516,441 (bull) per share, using free cash flow of ₩2.9T, net cash of ₩1.5T, growth of -5.0% and a discount rate of 9.0%, as of H1 2026.

The last close was ₩36,050 on 2026-10-12, far below the whole range. This gap is unusual enough that the simple model should be read with caution. It relies on a single free cash flow figure (trailing free cash flow in the data pack is ₩2.2T, lower than the ₩2.9T the model uses) and sets aside the heavy liabilities, and borrowings data are not available. The model inputs are based on H1 2026 data, and this filing provides no new financial inputs, so nothing in the model changes because of it.

Closing view

The filing is mostly informational: it gives volume data but no profit data, so the earnings story is unchanged. The mixed volumes (stronger city gas, weaker power generation) are a limited indicator. The gap between the share price and our model fair value range is large, and it likely reflects the leverage, falling revenue and earnings swings noted at initiation as much as any mispricing. The next filing with actual revenue and profit figures would be the more meaningful update. Investor flow, foreign ownership and short-interest data remain unavailable.
