TL;DR: Formosa Petrochemical Corporation (FPCC, TWSE:6505) announced its Q2 2026 self-tallied consolidated results on July 9, 2026 through a material information disclosure (Item fifty-one) on the Taiwan Stock Exchange's Market Observation Post System; every profit-and-loss figure in this card is company self-tallied and has not been audited. Q2 self-tallied consolidated revenue was NT$182,982.93 million (1,829億8,293萬元), up NT$20,993.49 million or 13.0% from Q1's NT$161,989.44 million; the volume-price structure moved in opposite directions — a sales-volume effect of −NT$34.64 billion and a sales-price effect of +NT$55.63 billion. Per the company's account in the statutory disclosure (the company's attribution, not geopolitical facts independently verified by this site) — the escalation of the US-Iran conflict closed the Strait of Hormuz until mid-June and delayed crude deliveries, so the refinery cut Q2 utilization to 66.5% (the filing states this as "down 14.6% from the previous quarter" without specifying percentage points or a relative rate; this card reproduces the original wording); crude runs of 32.673 million barrels (359.0 thousand barrels per day) fell by 6.765 million barrels QoQ and product sales of 33.639 million barrels fell by 8.491 million barrels; the average product price of US$135.3 per barrel rose US$44.6 per barrel QoQ (Dubai crude up US$9.8 per barrel, plus a sharp widening of export fuel spreads as Middle East refined-product exports plunged during the closure and Asian countries restricted fuel exports — company's account). The olefin segment ran at 33.1% average utilization (filing wording: "down 19.8% from the previous quarter") with only one naphtha cracker in operation; product sales of 621,000 tonnes fell 405,000 tonnes QoQ; the average selling price of US$1,187 per tonne rose US$367 per tonne (ethylene +US$390, propylene +US$337, butadiene +US$457; MOPJ naphtha up US$246 per tonne plus Asian crackers cutting runs on feedstock shortages or declaring force majeure — company's account). The pivotal arithmetic structure on the profit side: operating profit of all three segments — refining, olefins, utilities — increased QoQ, yet because the company booked a NT$3.23 billion inventory valuation loss in Q2 against a NT$0.38 billion inventory valuation reversal gain booked in Q1 (an unfavorable swing of NT$3.61 billion), consolidated operating income actually fell NT$1.63 billion QoQ; non-operating income rose NT$1.98 billion (equity-method income favorable by NT$1.50 billion, cash dividend income favorable by NT$120 million), lifting pre-tax profit to NT$25,969.01 million, up NT$352.82 million from Q1's NT$25,616.19 million; after-tax profit was NT$20,775.26 million, after-tax profit attributable to the parent NT$20,777.90 million, and after-tax EPS attributable to the parent of NT$2.18. The first half swung to profit versus H1 2025: revenue NT$344,972.37 million, up 8.2% YoY; pre-tax profit NT$51,585.20 million (H1 2025: pre-tax loss of NT$4,706.05 million; an increase of NT$56,291.25 million); after-tax profit NT$41,181.87 million (H1 2025: after-tax loss of NT$3,821.14 million); after-tax profit attributable to the parent NT$41,185.63 million, EPS attributable to the parent of NT$4.32; operating income up NT$51.06 billion and non-operating income up NT$5.23 billion (foreign-exchange favorable by NT$3.26 billion). This is a single-company, single-source official-disclosure deep-dive card and is not extrapolated to Taiwan's refining/petrochemical industry as a whole; the three scopes (pre-tax, after-tax, attributable-to-parent) and the two comparison bases (Q2 QoQ, H1 YoY) are kept separate throughout.

The primary source is a statutory material information disclosure (Item fifty-one) on the Taiwan Stock Exchange's Market Observation Post System, presenting unfavorable facts (a NT$3.23 billion inventory valuation loss; olefin utilization of 33.1%) alongside favorable ones — not a single company's promotional copy. This card carries forward this site's attribution discipline: every P&L figure is labeled "company self-tallied, unaudited"; geopolitical attributions — the Strait of Hormuz closure, the US-Iran conflict, force majeure declarations, Asian countries' fuel-export restrictions — are each labeled as the company's account, not independently verified by this site; the three scopes (pre-tax / after-tax / attributable to parent) and the two comparison bases (QoQ / YoY) are kept separate. Under the v1.1.0 "hook × full-library synthesis" rule the single-source card was reworked: a full-library search on the lead's theme (window 2026-06-15 to 2026-07-10) added the same-day Q2 self-tally material filings of the other three of the Formosa Plastics Group's "Big Four" (Formosa Plastics 1301, Nan Ya Plastics 1303, Formosa Chemicals & Fibre 1326) filed on the same day, 2026-07-09, plus two 2026-07-09 CNA reports (FPCC's oil-price outlook; Strait of Hormuz traffic) as external corroboration, and links two of this site's published cards as an internal citation chain: each added item is a separate company's own disclosure — parallel-in-time only (the same US-Iran war / Strait of Hormuz event chain), no causal inference, not summed into a "group total," and no cross-inference; the Big Four's cross-shareholdings (siblings booking FPCC's equity-method contribution) are a parallel view of the cross-holding structure, not a cross-verification of FPCC's own results. The primary source contains no Japan-side facts, so under the "honest contrast, cut weak links" principle no Taiwan-Japan comparison section is forced; an internal citation links to this site's published card on the Japan side of the same Middle East geopolitical event chain, with no causal inference in either direction.

TL;DR

Formosa Petrochemical Corporation (FPCC, TWSE:6505) announced its Q2 2026 self-tallied consolidated results on July 9, 2026 through a material information disclosure (Item fifty-one) on the Taiwan Stock Exchange's Market Observation Post System — every P&L figure in this card is company self-tallied and unaudited. [F-015] Q2 self-tallied consolidated revenue was NT$182,982.93 million, up NT$20,993.49 million or 13.0% from Q1's NT$161,989.44 million; the volume-price structure moved one down, one up: a sales-volume effect of −NT$34.64 billion and a sales-price effect of +NT$55.63 billion. [F-001] Per the company's account: the escalation of the US-Iran conflict closed the Strait of Hormuz until mid-June and delayed crude deliveries, so the refinery cut Q2 utilization to 66.5% (filing wording: "down 14.6% from the previous quarter"); crude runs of 32.673 million barrels (359.0 thousand barrels per day) fell 6.765 million barrels QoQ; the average product price of US$135.3 per barrel rose US$44.6 per barrel QoQ. [F-002] The olefin segment's average utilization was 33.1% (filing wording: "down 19.8% from the previous quarter") with only one naphtha cracker running; product sales of 621,000 tonnes fell 405,000 tonnes QoQ; the average selling price of US$1,187 per tonne rose US$367 per tonne. [F-003] The pivotal arithmetic structure on the profit side: all three segments' operating profit increased QoQ, but a NT$3.23 billion inventory valuation loss booked in Q2 against a NT$0.38 billion inventory valuation reversal gain in Q1 (an unfavorable swing of NT$3.61 billion) meant operating income actually fell NT$1.63 billion; non-operating income rose NT$1.98 billion, and pre-tax profit reached NT$25,969.01 million, up NT$352.82 million QoQ. [F-005][F-006][F-007] After-tax profit was NT$20,775.26 million, after-tax profit attributable to the parent NT$20,777.90 million, and after-tax EPS attributable to the parent of NT$2.18. [F-005] The first half swung to profit versus H1 2025: revenue of NT$344,972.37 million (up 8.2% YoY), pre-tax profit of NT$51,585.20 million (H1 2025: a pre-tax loss of NT$4,706.05 million), after-tax profit attributable to the parent of NT$41,185.63 million, EPS attributable to the parent of NT$4.32. [F-008][F-012] All geopolitical attributions, including the Strait of Hormuz closure, are the company's statements in a statutory disclosure, not independently verified by this site; this is a single company's disclosure and is not extrapolated to the industry as a whole. v1.1.0 single-source rework (hook × full-library synthesis): this card uses the lead as a hook and, from the full library, adds the same-day (2026-07-09) Q2 self-tally material filings of the other three of the Formosa Plastics Group's "Big Four" (Formosa Plastics 1301, Nan Ya Plastics 1303, Formosa Chemicals & Fibre 1326) as a same-day contrast, plus two same-day CNA reports (FPCC's oil-price outlook; Strait of Hormuz traffic) as external corroboration, and links two of this site's published cards — all three siblings book FPCC's equity-method / dividend contribution on their own books, showing a parallel view of the group's cross-shareholding structure, yet each company's results belong to that company, are not summed into a group figure, do not constitute a cross-verification of FPCC's results, and are parallel-in-time only with no causal inference.

Main text

Nature of the disclosure: a statutory material information filing (Item fifty-one) — "self-tallied" means unaudited, and this card keeps that scope throughout

Formosa Petrochemical Corporation (台塑石化, TWSE:6505) published a material information disclosure on the Taiwan Stock Exchange's Market Observation Post System at 14:30 on July 9, 2026 (spokesperson date: July 9, 2026, i.e., year 115 of the ROC calendar), announcing its Q2 2026 self-tallied consolidated results; the applicable provision is Item fifty-one, the date of occurrence is July 9, 2026 (ROC 115/07/09), the publication date is July 10, 2026 (ROC 1150710); the filing entity is the company itself, and the "countermeasures" field reads "none". [F-015] (TWSE#1402889) The scope must be nailed down first: "self-tallied" figures are computed by the company itself and are not audited by accountants — a different evidentiary tier from formal financial reports; every P&L figure cited in this card carries this scope, and figures in the subsequently published financial report may differ from the self-tallied ones. Furthermore, the narrative elements in the disclosure — the closure of the Strait of Hormuz, the escalation of the US-Iran conflict, force majeure declarations by Asian naphtha crackers, Asian countries restricting fuel exports — are the company's attributions in a statutory disclosure; this site has not independently verified these geopolitical facts, and the entire card is labeled accordingly.

The volume-price structure behind Q2 revenue up 13.0% QoQ: volume effect −NT$34.64 billion, price effect +NT$55.63 billion — volume down, price up

Q2 2026 self-tallied consolidated revenue was NT$182,982.93 million (1,829億8,293萬元), up NT$20,993.49 million or 13.0% from Q1 2026's NT$161,989.44 million. The disclosure itself provides the volume-price decomposition: a sales-volume effect of −NT$34.64 billion and a sales-price effect of +NT$55.63 billion — that is, on volume changes alone revenue would have fallen; the quarter's entire revenue growth came from the price side, with the price effect absorbing the volume drag for a net gain of NT$20,993.49 million. [F-001] (TWSE#1402889) This "volume down, price up" structure recurs across all three business segments, bound to the filing's numbers below.

Segment-by-segment volume and price: refining down on volume and up on price (66.5% utilization), olefins running only one naphtha cracker (33.1%), utilities helped by summer power tariffs

Refining revenue rose 17.4% QoQ. On volume: Q2 crude runs were 32.673 million barrels (359.0 thousand barrels per day), down 6.765 million barrels from the prior quarter's 39.438 million barrels (438.2 thousand barrels per day); product sales of 33.639 million barrels fell 8.491 million barrels QoQ. The company's account: the escalation of the US-Iran conflict closed the Strait of Hormuz until mid-June, delaying crude deliveries, so the refinery cut Q2 utilization to 66.5% (the filing states this as "down 14.6% from the previous quarter"; the filing does not specify whether this is percentage points or a relative rate, and this card reproduces the original wording). On price: the Q2 average product price of US$135.3 per barrel rose US$44.6 per barrel QoQ; the company attributes this mainly to the Dubai crude average rising US$9.8 per barrel QoQ, plus Middle East refined-product exports plunging during the closure and Asian countries restricting fuel exports to stabilize domestic supply, which sharply widened export fuel spreads. [F-002] (TWSE#1402889)

Olefins revenue fell 15.1% QoQ — the only segment whose revenue declined from the prior quarter. On volume: Q2 average utilization was 33.1% (filing wording: "down 19.8% from the previous quarter"), and product sales of 621,000 tonnes fell 405,000 tonnes QoQ; the company's account: the Strait of Hormuz closure delayed naphtha deliveries, and with downstream petrochemical demand slowing and offtake turning cautious, the olefin plants kept only one naphtha cracker running. On price: the Q2 average selling price of US$1,187 per tonne rose US$367 per tonne QoQ (ethylene +US$390, propylene +US$337, butadiene +US$457 per tonne); the company attributes this mainly to the Q2 MOPJ naphtha average rising US$246 per tonne QoQ, plus Asian naphtha crackers successively cutting runs on feedstock shortages or declaring force majeure, tightening regional supply and pushing up product prices. [F-003] (TWSE#1402889)

Utilities revenue rose 16.7% QoQ; the company's account: Q2 covers summer electricity-tariff billing months, and with scheduled maintenance of large power-generation units completed, both power selling prices and volumes rose QoQ. [F-004] (TWSE#1402889)

The card's pivotal arithmetic structure: all three segments improved QoQ, yet operating income fell NT$1.63 billion — an unfavorable NT$3.61 billion inventory-valuation swing

Q2 consolidated operating income fell NT$1.63 billion from Q1 — yet the disclosure simultaneously states that operating profit in all three segments — refining, olefins, utilities — increased QoQ (refining: export fuel spreads widened markedly, offsetting procurement and inventory losses from crude prices falling month by month; olefins: naphtha price gains and tight regional supply drove sharp product-price increases, offsetting procurement and inventory losses from naphtha prices falling month by month; utilities: simultaneous gains in power selling prices and volumes offset higher fuel-coal costs — all per the company's account). The key to this coexistence is inventory valuation: in accordance with accounting standards the company revalued quarter-end inventories, booking a NT$3.23 billion inventory valuation loss in Q2 against a NT$0.38 billion inventory valuation reversal gain booked in Q1 — an unfavorable swing of NT$3.61 billion. [F-006] (TWSE#1402889) The filing does not give the amounts by which each segment's operating profit increased, and this card does not derive them.

Non-operating income rose NT$1.98 billion QoQ, with the filing listing the main items: equity-method income favorable by NT$1.50 billion (FPCC DILIGENCE favorable by NT$1.10 billion, 麥寮汽電 (Mailiao Power) favorable by NT$310 million); cash dividend income favorable by NT$120 million (Q2 dividend income: Formosa Plastics (台塑) NT$60 million, Formosa Chemicals & Fibre (台化) NT$30 million, 台塑網科 NT$20 million; no dividend income in Q1). [F-007] (TWSE#1402889)

The full profit picture (three scopes kept separate): Q2 self-tallied consolidated pre-tax profit was NT$25,969.01 million, up NT$352.82 million from Q1's NT$25,616.19 million; after-tax profit was NT$20,775.26 million, up NT$368.65 million from Q1's NT$20,406.61 million; after-tax profit attributable to the parent was NT$20,777.90 million, with after-tax EPS attributable to the parent of NT$2.18. [F-005] (TWSE#1402889) Operating income down NT$1.63 billion and non-operating income up NT$1.98 billion net out to the pre-tax profit increase of NT$352.82 million.

First half YoY: a swing to profit — pre-tax profit of NT$51,585.20 million versus a pre-tax loss of NT$4,706.05 million in H1 2025

The comparison base switches to "H1 2026 vs H1 2025" (year-on-year, separate from the QoQ base above). H1 2026 self-tallied consolidated revenue was NT$344,972.37 million, up NT$26,157.60 million or 8.2% from H1 2025's NT$318,814.77 million; the volume-price structure mirrors Q2's: a sales-volume effect of −NT$48.63 billion and a sales-price effect of +NT$74.79 billion. [F-008] (TWSE#1402889)

By segment: refining revenue rose 16.1% YoY — H1 crude runs of 72.111 million barrels (398.4 thousand barrels per day) fell 7.507 million barrels from 79.618 million barrels (439.9 thousand barrels per day) H1 2025; product sales of 75.769 million barrels fell 8.956 million barrels YoY; H1 utilization was 73.8% (filing wording: "down 7.7% from H1 2025", which the company attributes to delayed crude deliveries); the average product price rose US$28.5 per barrel YoY (company's account: Dubai crude up US$19.3 per barrel plus sharply stronger export fuel spreads). [F-009] Olefins revenue fell 18.5% YoY — H1 average utilization was 42.9% (filing wording: "down 15.6% from H1 2025"), product sales of 1.647 million tonnes fell 703,000 tonnes YoY (company's attribution: delayed naphtha deliveries plus a weak downstream petrochemical market, with crackers adjusting runs); the average selling price of US$958 per tonne rose US$167 per tonne YoY (ethylene +US$207, propylene +US$227, butadiene +US$350, pyrolysis gasoline +US$186 per tonne). [F-010] Utilities revenue fell 10.9% YoY (both electricity and steam supplied to the plant complex declined YoY). [F-011] (TWSE#1402889)

On profit (three scopes kept separate): H1 2026 self-tallied consolidated pre-tax profit was NT$51,585.20 million, against a pre-tax loss of NT$4,706.05 million in H1 2025 — an increase of NT$56,291.25 million and a swing to profit; after-tax profit was NT$41,181.87 million, against an after-tax loss of NT$3,821.14 million in H1 2025, an increase of NT$45,003.01 million; after-tax profit attributable to the parent was NT$41,185.63 million, with after-tax EPS attributable to the parent of NT$4.32. [F-012] (TWSE#1402889) Structurally, operating income rose NT$51.06 billion: the company explains that refining and olefins both benefited from H1 2026's "surge then decline" path in crude/naphtha prices (versus the "month-by-month decline" H1 2025), generating procurement and inventory gains, with refining further helped by stronger export fuel spreads; utilities' operating profit declined YoY (lower power and steam sales volumes plus geopolitical tensions pushing up fuel-coal costs — company's account); H1 booked a NT$2.85 billion inventory valuation loss, unfavorable by NT$1.73 billion versus the NT$1.12 billion inventory valuation loss in H1 2025. [F-013] Non-operating income rose NT$5.23 billion, mainly: foreign-exchange results favorable by NT$3.26 billion (an FX gain of NT$1.31 billion in H1 2026 versus an FX loss of NT$1.95 billion in H1 2025); equity-method income favorable by NT$760 million (FPCC DILIGENCE favorable by NT$1.10 billion, 麥寮汽電 (Mailiao Power) favorable by NT$50 million, 台塑資源 (Formosa Resources) unfavorable by NT$470 million); other income favorable by NT$740 million. [F-014] (TWSE#1402889)

Taiwan-Japan contrast (internal citation): two industries under the same Middle East geopolitical event — juxtaposition only, no causal inference

This site's published card of June 13, 2026 (ANK-2026-06-13-001) recorded the procurement squeeze on Japanese manufacturers under the Middle East situation: in the 57th Meisho survey, 90% of companies reported higher purchase prices and over 70% had made price-hike requests. The Formosa Petrochemical disclosure in this card shows the same geopolitical event chain (Middle East situation / Strait of Hormuz) as it appeared on Taiwan's refining-petrochemical side — per the company's account, the strait closure was simultaneously a "volume subtraction" (delayed crude and naphtha deliveries, utilization cuts) and a "price addition" (wider export fuel spreads, higher olefin prices). The contrast stops at "two industries' exposure to the same geopolitical event": the Japan side is corporate survey opinion as of June 2026, the Taiwan side is a single company's Q2 2026 self-tallied results — different samples, timings and natures, and no causality may be inferred between them.

Hook × full-library synthesis (v1.1.0 single-source rework): a same-day Q2 self-tally contrast across the Formosa Big Four plus FPCC's oil-price outlook — juxtaposition only, no causal inference, not summed into a group figure

New in the v1.1.0 rework: using the lead (FPCC Q2 self-tally, TWSE#1402889) as a hook, a full-library search (window 2026-06-15 to 2026-07-10) adds the Q2 self-tally material filings that the other three of the Formosa Plastics Group's "Big Four" published on the same day, 2026-07-09, plus two 2026-07-09 CNA reports as external corroboration. The rule: each is a separate company's own disclosure — juxtaposition only (same day, the same US-Iran war / Strait of Hormuz event chain), no causal inference, not summed into a "group total" (the filings contain no group total), and no cross-inference.

Reading the cross-shareholding network (frame reconstruction): FPCC appears in each of the three siblings' Q2 self-tally disclosures as an "equity-method investee / source of dividends and investment income" — Formosa Plastics books FPCC at NT$5.91 billion, Nan Ya at NT$4.80 billion, and FCFC lists FPCC's dividend of NT$440 million and equity-method of NT$420 million. This and the lead's own FPCC "non-operating — equity-method income (FPCC DILIGENCE, Mailiao Power)" (F-007) are the two ends of the group's cross-shareholding structure: the siblings hold FPCC shares and book FPCC's contribution, the opposite direction from the lead. This must be nailed down: this is not a second-source cross-verification of FPCC's Q2 results; the siblings' booked amounts are "FPCC's contribution as booked on the siblings' books," not FPCC's own results; the four companies' EPS and pre-tax profit belong to four companies and must not be summed into a group figure.

FAQ

Q: How much did Formosa Petrochemical earn in Q2 2026 on a self-tallied basis?

Q2 self-tallied consolidated pre-tax profit was NT$25,969.01 million (up NT$352.82 million QoQ), after-tax profit was NT$20,775.26 million (up NT$368.65 million QoQ), after-tax profit attributable to the parent was NT$20,777.90 million, and after-tax EPS attributable to the parent was NT$2.18.

The three scopes (pre-tax / after-tax / attributable to parent) must be cited separately; all figures are company self-tallied and unaudited, with the formal financial report pending the company's later publication (TWSE#1402889).

Q: Why did consolidated operating income fall NT$1.63 billion when all three segments' operating profit rose QoQ?

The key is the inventory-valuation swing: Q2 booked a NT$3.23 billion inventory valuation loss, whereas Q1 had booked a NT$0.38 billion inventory valuation reversal gain — an unfavorable swing of NT$3.61 billion. In Q2 2026 vs Q1 2026, this accounting valuation item outweighed the simultaneous operating-profit improvement across refining, olefins and utilities, so consolidated operating income actually fell NT$1.63 billion.

The inventory valuation is performed on quarter-end inventories in accordance with accounting standards. The filing does not give the segment-level increase amounts and this card does not derive them; pre-tax profit still rose NT$352.82 million QoQ thanks to non-operating income rising NT$1.98 billion (TWSE#1402889).

Q: What was the impact of the Strait of Hormuz closure on Formosa Petrochemical's Q2?

Per the company's account in the statutory disclosure (not independently verified by this site): the closure produced "volume down" and "price up" at the same time. Volume side — crude and naphtha deliveries were delayed, refinery utilization was cut to 66.5% and crude runs fell 6.765 million barrels QoQ; olefin utilization was 33.1% with only one naphtha cracker running. Price side — Middle East refined-product exports plunged and Asian countries restricted fuel exports, sharply widening export fuel spreads; the average product price of US$135.3 per barrel rose US$44.6 per barrel QoQ, and the olefin average selling price of US$1,187 per tonne rose US$367 per tonne.

The overall result shows up in the revenue decomposition: a sales-volume effect of −NT$34.64 billion and a sales-price effect of +NT$55.63 billion. The company states the closure lasted "until mid-June"; the post-closure trajectory of volumes and spreads in Q3 awaits later disclosures (TWSE#1402889).

Q: Why did Formosa Petrochemical swing to profit in the first half of 2026?

H1 2026 self-tallied consolidated pre-tax profit was NT$51,585.20 million, against a pre-tax loss of NT$4,706.05 million in H1 2025 — an increase of NT$56,291.25 million. The company's stated main drivers: operating income rose NT$51.06 billion — refining and olefins benefited from H1 2026's "surge then decline" path in crude/naphtha prices (versus the "month-by-month decline" H1 2025), generating procurement and inventory gains, plus stronger export fuel spreads; non-operating income rose NT$5.23 billion, including a favorable NT$3.26 billion in foreign-exchange results (an FX gain of NT$1.31 billion in H1 2026 versus an FX loss of NT$1.95 billion in H1 2025).

Note the countervailing items: utilities' operating profit fell YoY (lower power and steam sales plus higher fuel-coal costs), H1 still booked a NT$2.85 billion inventory valuation loss (unfavorable by NT$1.73 billion versus NT$1.12 billion H1 2025), and olefins revenue fell 18.5% YoY. After-tax profit attributable to the parent was NT$41,185.63 million with EPS attributable to the parent of NT$4.32 — all self-tallied figures (TWSE#1402889).

Q: How do "self-tallied results" differ from formal financial reports, and how reliable are these numbers?

"Self-tallied" figures are computed by the company itself without an accountant's audit, disclosed by statute through the stock exchange's material information system (this filing falls under Item fifty-one); formal financial reports are published separately after audit (annual) or review (quarterly), and the two sets of numbers may differ.

This card's handling: every P&L figure is labeled "company self-tallied, unaudited"; attributions such as the Strait of Hormuz closure are labeled as the company's account; utilization-change magnitudes are reproduced in the filing's original wording without conversion; numbers absent from the filing (such as Q2 year-on-year comparisons or segment-level operating-profit increase amounts) are never generated (TWSE#1402889).

J-Units

J-001: The correct reading of Q2 profit is a three-layer structure: all three segments' operating profit rose QoQ (per the company's account, the core business improved in a volume-down, price-up quarter), but an unfavorable NT$3.61 billion inventory-valuation swing pushed consolidated operating income down NT$1.63 billion, and non-operating income's NT$1.98 billion increase then lifted pre-tax profit to a net gain of NT$352.82 million — reading only "operating income fell" misreads the core business as weakening, and reading only "pre-tax profit rose" misses the accounting-valuation swing; the set must be cited together - confidence: medium - basis: official_statement

J-002: Per the company's attributions in the statutory disclosure, the single event of the Strait of Hormuz closure was simultaneously a volume subtraction for Formosa Petrochemical in Q2 (delayed crude and naphtha deliveries → refinery utilization 66.5%, olefins 33.1% with one naphtha cracker running) and a price addition (plunging Middle East refined-product exports and Asian export restrictions → wider export fuel spreads; Asian crackers' run cuts and force majeure → higher olefin prices) — the revenue decomposition (volume −NT$34.64 billion, price +NT$55.63 billion) is directionally consistent with this narrative; but this is the company's account, and this site has not independently verified the geopolitical facts - confidence: medium - basis: official_statement

J-003: The H1 YoY "increase of NT$56,291.25 million" is measured against H1 2025's pre-tax loss of NT$4,706.05 million — the swing-to-profit magnitude contains a low-base component, and the procurement and inventory gains in the company's attribution are accounting effects of the price path (surge-then-decline vs month-by-month decline); citations of the H1 figures should state that the base period was a loss and note the countervailing items (utilities' operating profit down, olefins revenue down 18.5% YoY) - confidence: medium - basis: official_statement

J-004: Single-source rework synthesis discipline (v1.1.0): the added same-day Q2 self-tallies of the Formosa Big Four (Formosa Plastics 1301, Nan Ya 1303, FCFC 1326) and the lead FPCC (6505) are juxtaposition only — same day 2026-07-09, the same US-Iran war / Strait of Hormuz event chain, yet four independent companies' own disclosures. Three rules: (1) do not sum (the filings contain no "group total" EPS or profit; the four companies' figures belong to four companies and cannot be added); (2) cross-shareholding is not cross-verification (Formosa Plastics books FPCC at NT$5.91 billion, Nan Ya at NT$4.80 billion, FCFC lists dividend NT$440 million and equity-method NT$420 million, all "bookings of FPCC's contribution" on the siblings' books, the opposite direction from the lead, not a second source for FPCC's own results); (3) the CNA oil-price outlook (CNA#1381292) and Strait of Hormuz traffic (CNA#1401583) are report-citation corroboration, not independently verified by this site, with no causal inference - confidence: medium - basis: news_aggregation

P-Units

P-001: All figures in this card are company self-tallied; whether the self-tallied numbers match the formal financial report for Q2/H1 2026 after accountants' review awaits the company's later publication ### P-002: The company states the Strait of Hormuz closure lasted "until mid-June"; the post-closure Q3 trajectory of crude runs, olefin utilization (Q2: 33.1%, one naphtha cracker running) and fuel/olefin spreads awaits subsequent monthly revenue and Q3 self-tallied disclosures ### P-003: The NT$3.23 billion inventory valuation loss booked in Q2 is the quarter-end valuation result; whether Q3 brings a valuation loss or a reversal gain depends on crude and naphtha price paths and awaits later disclosures

❓ FAQ

How much did Formosa Petrochemical earn in Q2 2026 on a self-tallied basis?

Q2 self-tallied consolidated pre-tax profit was NT$25,969.01 million (up NT$352.82 million QoQ), after-tax profit was NT$20,775.26 million (up NT$368.65 million QoQ), after-tax profit attributable to the parent was NT$20,777.90 million, and after-tax EPS attributable to the parent was NT$2.18. The three scopes (pre-tax / after-tax / attributable to parent) must be cited separately; all figures are company self-tallied and unaudited, with the formal financial report pending the company's later publication (TWSE#1402889).

Why did consolidated operating income fall NT$1.63 billion when all three segments' operating profit rose QoQ?

The key is the inventory-valuation swing: Q2 booked a NT$3.23 billion inventory valuation loss, whereas Q1 had booked a NT$0.38 billion inventory valuation reversal gain — an unfavorable swing of NT$3.61 billion. In Q2 2026 vs Q1 2026, this accounting valuation item outweighed the simultaneous operating-profit improvement across refining, olefins and utilities, so consolidated operating income actually fell NT$1.63 billion. The inventory valuation is performed on quarter-end inventories in accordance with accounting standards. The filing does not give the segment-level increase amounts and this card does not derive them; pre-tax profit still rose NT$352.82 million QoQ thanks to non-operating income rising NT$1.98 billion (TWSE#1402889).

What was the impact of the Strait of Hormuz closure on Formosa Petrochemical's Q2?

Per the company's account in the statutory disclosure (not independently verified by this site): the closure produced "volume down" and "price up" at the same time. Volume side — crude and naphtha deliveries were delayed, refinery utilization was cut to 66.5% and crude runs fell 6.765 million barrels QoQ; olefin utilization was 33.1% with only one naphtha cracker running. Price side — Middle East refined-product exports plunged and Asian countries restricted fuel exports, sharply widening export fuel spreads; the average product price of US$135.3 per barrel rose US$44.6 per barrel QoQ, and the olefin average selling price of US$1,187 per tonne rose US$367 per tonne. The overall result shows up in the revenue decomposition: a sales-volume effect of −NT$34.64 billion and a sales-price effect of +NT$55.63 billion. The company states the closure lasted "until mid-June"; the post-closure trajectory of volumes and spreads in Q3 awaits later disclosures (TWSE#1402889).

Why did Formosa Petrochemical swing to profit in the first half of 2026?

H1 2026 self-tallied consolidated pre-tax profit was NT$51,585.20 million, against a pre-tax loss of NT$4,706.05 million in H1 2025 — an increase of NT$56,291.25 million. The company's stated main drivers: operating income rose NT$51.06 billion — refining and olefins benefited from H1 2026's "surge then decline" path in crude/naphtha prices (versus the "month-by-month decline" H1 2025), generating procurement and inventory gains, plus stronger export fuel spreads; non-operating income rose NT$5.23 billion, including a favorable NT$3.26 billion in foreign-exchange results (an FX gain of NT$1.31 billion in H1 2026 versus an FX loss of NT$1.95 billion in H1 2025). Note the countervailing items: utilities' operating profit fell YoY (lower power and steam sales plus higher fuel-coal costs), H1 still booked a NT$2.85 billion inventory valuation loss (unfavorable by NT$1.73 billion versus NT$1.12 billion H1 2025), and olefins revenue fell 18.5% YoY. After-tax profit attributable to the parent was NT$41,185.63 million with EPS attributable to the parent of NT$4.32 — all self-tallied figures (TWSE#1402889).

How do "self-tallied results" differ from formal financial reports, and how reliable are these numbers?

"Self-tallied" figures are computed by the company itself without an accountant's audit, disclosed by statute through the stock exchange's material information system (this filing falls under Item fifty-one); formal financial reports are published separately after audit (annual) or review (quarterly), and the two sets of numbers may differ. This card's handling: every P&L figure is labeled "company self-tallied, unaudited"; attributions such as the Strait of Hormuz closure are labeled as the company's account; utilization-change magnitudes are reproduced in the filing's original wording without conversion; numbers absent from the filing (such as Q2 year-on-year comparisons or segment-level operating-profit increase amounts) are never generated (TWSE#1402889). ---

🧠 編輯判斷（J-Units）

The correct reading of Q2 profit is a three-layer structure: all three segments' operating profit rose QoQ (per the company's account, the core business improved in a volume-down, price-up quarter), but an unfavorable NT$3.61 billion inventory-valuation swing pushed consolidated operating income down NT$1.63 billion, and non-operating income's NT$1.98 billion increase then lifted pre-tax profit to a net gain of NT$352.82 million — reading only "operating income fell" misreads the core business as weakening, and reading only "pre-tax profit rose" misses the accounting-valuation swing; the set must be cited together
Confidence: medium
Per the company's attributions in the statutory disclosure, the single event of the Strait of Hormuz closure was simultaneously a volume subtraction for Formosa Petrochemical in Q2 (delayed crude and naphtha deliveries → refinery utilization 66.5%, olefins 33.1% with one naphtha cracker running) and a price addition (plunging Middle East refined-product exports and Asian export restrictions → wider export fuel spreads; Asian crackers' run cuts and force majeure → higher olefin prices) — the revenue decomposition (volume −NT$34.64 billion, price +NT$55.63 billion) is directionally consistent with this narrative; but this is the company's account, and this site has not independently verified the geopolitical facts
Confidence: medium
The H1 YoY "increase of NT$56,291.25 million" is measured against H1 2025's pre-tax loss of NT$4,706.05 million — the swing-to-profit magnitude contains a low-base component, and the procurement and inventory gains in the company's attribution are accounting effects of the price path (surge-then-decline vs month-by-month decline); citations of the H1 figures should state that the base period was a loss and note the countervailing items (utilities' operating profit down, olefins revenue down 18.5% YoY)
Confidence: medium
Single-source rework synthesis discipline (v1.1.0): the added same-day Q2 self-tallies of the Formosa Big Four (Formosa Plastics 1301, Nan Ya 1303, FCFC 1326) and the lead FPCC (6505) are juxtaposition only — same day 2026-07-09, the same US-Iran war / Strait of Hormuz event chain, yet four independent companies' own disclosures. Three rules: (1) do not sum (the filings contain no "group total" EPS or profit; the four companies' figures belong to four companies and cannot be added); (2) cross-shareholding is not cross-verification (Formosa Plastics books FPCC at NT$5.91 billion, Nan Ya at NT$4.80 billion, FCFC lists dividend NT$440 million and equity-method NT$420 million, all "bookings of FPCC's contribution" on the siblings' books, the opposite direction from the lead, not a second source for FPCC's own results); (3) the CNA oil-price outlook (CNA#1381292) and Strait of Hormuz traffic (CNA#1401583) are report-citation corroboration, not independently verified by this site, with no causal inference
Confidence: medium

🔮 待驗證假設（P-Units）

All figures in this card are company self-tallied; whether the self-tallied numbers match the formal financial report for Q2/H1 2026 after accountants' review awaits the company's later publication
Status: open
The company states the Strait of Hormuz closure lasted "until mid-June"; the post-closure Q3 trajectory of crude runs, olefin utilization (Q2: 33.1%, one naphtha cracker running) and fuel/olefin spreads awaits subsequent monthly revenue and Q3 self-tallied disclosures
Status: open
The NT$3.23 billion inventory valuation loss booked in Q2 is the quarter-end valuation result; whether Q3 brings a valuation loss or a reversal gain depends on crude and naphtha price paths and awaits later disclosures
