IRPC heads into its November 5 earnings release with the stock at its weakest level in a month, a mean analyst target sitting below the current price, and institutional ownership concentrated firmly in state hands.
The price story is straightforward. IRPC closed Thursday at THB 2.88, down 4% on the week and roughly flat over the past month. The move is modest in isolation, but it puts the stock below the consensus mean price target of THB 2.28, a gap worth noting as a caution: that target is 18 days old and close to the 14-day freshness threshold, so it may not fully reflect the stock's recent drift lower. Closest Thai peers TOP and BCP fared worse, dropping 6.4% and 3.7% respectively on the week, suggesting broad sector pressure rather than anything IRPC-specific. , by contrast, managed a 5.4% weekly gain, a reminder that the Thai energy complex is not moving in one direction.
The ownership structure is the most distinctive feature of this stock. PTT Public Company Limited controls 48.1% of shares, making IRPC effectively a state-controlled refiner. The Social Security Office of Thailand holds a further 2%, and the remaining institutional register is thin: Vanguard at 2.1%, BlackRock at 1.2%, with Dimensional and State Street each adding smaller positions in the most recent reporting period. Dimensional added 11.8 million shares and American Century 13.1 million through September 30, while First Trust trimmed by 3.9 million. None of these moves is large enough relative to the float to shift the picture materially. Borrowing data is effectively absent for this name, with the most recent lending-market reading dating to September 2020, so there is no useful short interest or availability signal to draw on.
The valuation picture is inexpensive but softening. IRPC trades on a price-to-book of 0.74 and a price-to-earnings of 9.7x, with both multiples having drifted lower over the past 30 days. The EV/EBITDA of 5.8x has nudged higher over the same period, reflecting the compression in market cap rather than any improvement in earnings. Among ORTEX factor scores, the dividend rank at the 86th percentile is the standout, though dividend history data has not been updated since early 2022 and is therefore stale. The EV/EBIT efficiency score ranks at the 78th percentile, consistent with a low-cost, capital-heavy refining operation that generates reasonable returns on invested capital without attracting strong growth interest. Analyst recommendation differentiation and EPS surprise both sit near the 50th percentile, a neutral read.
The most recent insider activity on record is a 70,000-share sale at THB 3.10 in September 2026 by a company reporter-level official, a low-significance transaction at best. Net insider activity over the prior 90 days comes to minus 140,000 shares, though the total value is not calculable in USD terms from the available data. The selling occurred with the stock above its current level, which is a small note of context rather than a meaningful signal.
Recent earnings reactions have been positive. The last three results events produced next-day gains of 1.6%, 2.5%, and 11.5%, with five-day moves running similarly higher. The 11.5% one-day jump following the August 11 release stands out. The November 5 print is the next date to watch, both for whether refining margin trends have continued through Q3 and for any guidance on the petrochemical demand backdrop that PTT's broader group has been navigating.
