FORMOSA PETROCHEMICAL CORPORATION 2025 Business Report

Foreword ：

The year 2025 was one defined by significant challenges and pivotal turning points. International oil price trends mirrored turbulent ocean waves, fluctuating repeatedly and causing our quarterly revenue and profit performance to ebb and flow with market volatility. At the beginning of the year, as global central banks entered a rate-cutting cycle, there was widespread anticipation for economic recovery and improved energy demand. However, the situation took a sharp downturn in April. As OPEC+ initiated production increase plans and international trade tensions escalated due to new tariff measures, market sentiment turned conservative. This led to a downward revision of crude oil demand in the second quarter, causing prices to retreat rapidly.

Despite short-term support in the third quarter from the summer driving peak and geopolitical tensions in the Middle East, the environment grew more severe toward year-end. With the conclusion of the peak season, record-high U.S. shale oil production, and slower-than-expected recovery in Asian petrochemical demand, pessimistic sentiment persisted, leaving oil prices to close the year at a relative low. Under such grueling external conditions, the Company demonstrated formidable operational resilience through flexible scheduling and stringent cost control. In 2025, our pre-tax profit reached NT$12.7 billion, a substantial 93.6% increase year-on-year, proving our ability to deliver exceptional results even during an industry downturn.

2025 Financial and Operational Performance Review ：

(In Thousands of NT Dollars)

	2025	2024	% Change
Consolidated Revenue	626,159,096	663,823,047	-5.7%
Consolidated Operating Profit	10,878,946	-651,435	-
Consolidated Pre-tax Income	12,712,220	6,567,110	93.6%
Earnings per Share (NTD)	1.04	0.63	65.1%

Petroleum Refining ：

In 2025, the Refining division returned to a growth trajectory, showing marked improvement over 2024 and successfully turning a profit. Falling oil prices spurred demand for petroleum products in Europe and the U.S. Furthermore, supply remained tight due to the slow recovery of Russian refineries following drone attacks and the permanent closure of refineries in Europe, the U.S., and Japan. With low global inventories, product cracks began to widen. Additionally, the impact of government-mandated price absorption for domestic fuel narrowed compared to the previous year, aiding profit recovery.

In terms of production, the average refining throughput in 2025 was 447,000 barrels per day, up 9.8% from 2024. This increase was driven by improved margins and the Company’s decision to raise utilization rates and optimize product yields.

For the domestic market, sales volume of gasoline and diesel fell slightly by 1.7%. While gasoline demand dipped due to the rising market share of hybrid and electric vehicles, our gas station market share remained steady at 22.3%. The "Formosa Oil APP" reached 730,000 members by December 2025, fostering loyalty through cross-industry collaborations and highprofile sports sponsorships.

For the export market, gasoline exports totaled 2,925 thousand kiloliters (down 5.4%), while diesel exports reached 8,792 thousand kiloliters (up 13.7%). Strategic partnerships with traders allowed us to expand in Australia, New Zealand, and the Philippines. Jet fuel sales also rose by 14.9% due to the robust recovery of international travel. Furthermore, we successfully produced 5,500 metric tons of Sustainable Aviation Fuel (SAF) in 2025 using co-processing technology. This initiative aligns with the 2050 Net-Zero goal, reducing carbon emissions while maintaining compatibility with existing infrastructure.

Basic Petrochemical Materials Business ：

The global petrochemical market faced headwinds in 2025 as trade barriers and tariffs hindered demand. Coupled with China’s aggressive capacity expansion, the oversupply in Asia led to significant price drops for ethylene, propylene, and butadiene. Although we raised capacity utilization from 52% to 60% through downstream integration and flexible feedstock sourcing,

narrow price spreads and increased inventory losses resulted in a wider loss compared to 2024.

Utilities Business ：

The primary goal of our utilities business is to provide stable electricity and steam supply to our plants. In 2025, international coal prices retreated due to increased global production and the rising share of renewable energy. By flexibly adjusting power dispatch during low-load periods, we improved internal efficiency and supported the stability of Taiwan's national power grid during critical windows. The division’s profit grew by 15.9% year-onyear, serving as a vital pillar of corporate resilience.

2026 Sales Targets ：

For petroleum products, our estimated sales volume for gasoline and gasoil are 5,870 thousand KL and 9,928 thousand KL, respectively. Regarding Sustainable Aviation Fuel (SAF), we aim to maintain a supply of 5,500 metric tons to domestic airlines; production volumes will be further scaled up once the new used cooking oil recycling facilities are completed. In terms of domestic sales strategy, the Company will continue to drive digital transformation to enhance refueling convenience. We will promote the "Formosa Oil APP" through diverse marketing campaigns and expanded cross-industry collaborations to increase consumer stickiness, with a target of reaching 1 million APP members by the end of 2026. In overseas markets, we will deepen partnerships with oil majors and traders to consistently explore potential markets and boost overseas sales volumes.

For petrochemical products, China’s policies to stimulate domestic demand are expected to drive consumption growth. Coupled with the global industry's accelerated restructuring, consolidation, and the phasing out of inefficient capacity, the supply-demand imbalance is likely to improve, paving the way for a modest industry recovery. The Company will optimize its production and sales allocation based on market dynamics, adopting flexible and diversified feedstock strategies to reduce costs while continuing downstream integration to enhance capacity utilization. Projected sales targets include 2,145 thousand tonnes of ethylene, 1,714 thousand tonnes of propylene, and 294 thousand tonnes of butadiene. In addition to supplying

downstream plants according to their production schedules, export volumes will be managed based on market conditions when price spreads are favorable. As for the Utility division, our primary objective is to ensure a stable supply of electricity and steam to support plant operations and meet process demands. We will also increase the operation of power generators to support the stability of Taiwan's national power grid.

Future Outlook ：

As we move into 2026, the global economy remains in a state of flux, by easing inflation, geopolitical issues, and an accelerated energy transition. The traditional refining and petrochemical industries are at a critical crossroads of "survival" versus "transformation." With the implementation of Taiwan's carbon fee and the rise of global low-carbon supply chains, industrial competition has shifted from a pure focus on economies of scale to a race of resilience and transformation speed.

In response to market skepticism regarding the industry's prospects, the Company is redefining industrial value with a more efficient, lower-carbon profile. Years ago, we integrated AI intelligent applications into the core of our digital transformation, optimizing process parameters to enhance energy efficiency and achieve significant low-carbon benefits. In 2025, our greenhouse gas emissions fell to 24.39 million tonnes, successfully meeting our short-term goal of a 22% reduction from the base year. Regarding our product mix, we flexibly adjust yields based on market dynamics and continue to increase the proportion of low-carbon products.

Looking ahead, the Company will continue to strengthen its advantages in "Petroleum Refining" and " Basic Petrochemical Raw Materials." By utilizing these dual engines to drive operational momentum, we will demonstrate competitive resilience amidst the wave of energy transition, ensuring our leading position and achieving profitable growth to reward our shareholders for their long-term support and encouragement.

Independent Auditors’ Report Translated from Chinese

To the Board of Directors and Stockholders of Formosa Petrochemical Corporation

Opinion

We have audited the accompanying consolidated balance sheets of Formosa Petrochemical Corporation (the “Company”) and its subsidiaries as of December 31, 2025 and 2024, and the related consolidated statements of comprehensive income, changes in equity and cash flows for the years ended December 31, 2025 and 2024, and notes to the consolidated financial statements, including the summary of material accounting policies (together “the consolidated financial statements”).

In our opinion, based on our audits and the reports of the other auditors (please refer to the Other Matter – Making Reference to the Audits of Other Auditors section of our report), the consolidated financial statements referred to above present fairly, in all material respects, the consolidated financial position of the Company and its subsidiaries as of December 31, 2025 and 2024, and their consolidated financial performance and cash flows for the years ended December 31, 2025 and 2024, in conformity with the requirements of the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Financial Reporting Standards, International Accounting Standards, Interpretations developed by the International Financial Reporting Interpretations Committee or the former Standing Interpretations Committee as endorsed by Financial Supervisory Commission of the Republic of China.

Basis for Opinion

We conducted our audits in accordance with the Regulations Governing Financial Statement Audit and Attestation Engagements of Certified Public Accountants and the Standards on Auditing of the Republic of China. Our responsibilities under those standards are further described in the Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements section of our report. We are independent of the Company and its subsidiaries in accordance with the Norm of Professional Ethics for Certified Public Accountant of the Republic of China (the “Norm”), and we have fulfilled our other ethical responsibilities in accordance with the Norm. Based on our audits and the reports of the other auditors, we believe that the audit evidence we have obtained is sufficient and appropriate to provide a basis for our opinion.

Key Audit Matters

Key audit matters are those matters that, in our professional judgment, were of most significance in our audit of 2025 consolidated financial statements. These matters were addressed in the context of our audit of the consolidated financial statements as a whole, and in forming our opinion thereon, and we do not provide a separate opinion on these matters.

Revenue recognition

Revenue is primarily driven by refining and sales of petroleum. The Company recognized operating revenues of NT$626,159,096 thousand during 2025, which was a significant and material amount in terms of financial performance and earning distribution. Therefore, revenue recognition is determined as a key audit matter.

The audit procedures we performed regarding revenue recognition included but not limited to: evaluate the appropriateness of the accounting policies for revenue recognition; understand the transaction process and perform tests of control on the effectiveness of control points; inspect the terms of transaction to ensure obligation of customers contract ； the appropriate timing of revenue recognition; obtain confirmation letter on revenue from the Company’s and its subsidiaries’ top 10 customers that are related parities; understand nature and rationality of transactions with the Company’s and its subsidiaries’ newly added top 10 customers, inspect the source document and proof of the accounts receivable collection, and confirm that the remitters match the customers; for a period before and after the balance sheet date, select significant sales and sales return transactions and inspect the supporting document to ensure proper cut off.

We also consider the appropriateness of the revenue disclosure included in note 4 and note 6(17) of the notes to the consolidated financial statements.

Valuation of inventories

As of December 31, 2025, the inventories amounted to NT$65,290,907 thousand, representing 16% of total assets, which was significant to the financial statements. Inventories consists of raw materials, finished goods and work in process which were measured at the lower of cost or net realizable value. As the fluctuation of material prices such as crude oil, could lead to value fluctuation of inventories, resulting in complex calculation of measurement of the lower of cost or net realizable value, therefore, valuation of inventories is identified as a key audit matter.

The audit procedures we performed regarding inventories valuation included but not limited to: evaluate the appropriateness of the accounting policies for inventories valuation; understand the transaction process and perform tests of control on the effectiveness of control points; inspect yearend inventory counting plan and observe the physical inventory count to verify the accuracy of inventory volume; test that inventory pricing correctly used weighted average method; perform tests on the net realizable value used by the management to verify its accuracy.

We also consider the appropriateness of inventories disclosure included in note 4 and note 6(6) of the notes to the consolidated financial statements.

Other Matter – Making Reference to the Audits of Other Auditors

We did not audit the financial statements of certain associates and joint ventures accounted for under the equity method whose statements are based solely on the reports of the other auditors. These associates and joint ventures under equity method amounted to NT$6,985,692 thousand and NT8,417,237 thousand, both representing 2% of consolidated total assets as of December 31, 2025 and 2024. The related shares of profit or loss of the associates and joint ventures under the equity method amounted to NT$(157,638) thousand and NT$(81,651) thousand, both representing (1)% of the consolidated net income before tax for the years ended December 31, 2025 and 2024, and the related shares of other comprehensive income (loss) from the associates and joint ventures under the equity method amounted to NT$70,979 thousand and NT$200,409 thousand, representing 0% and (1)% of the consolidated other comprehensive income for the years ended December 31, 2025 and 2024, respectively.

Responsibilities of Management and Those Charged with Governance for the Consolidated Financial Statements

Management is responsible for the preparation and fair presentation of the consolidated financial statements in accordance with the requirements of the Regulations Governing the Preparation of Financial Reports by Securities Issuers and International Financial Reporting Standards, International Accounting Standards, Interpretations developed by the International Financial Reporting Interpretations Committee or the former Standing Interpretations Committee as endorsed by Financial Supervisory Commission of the Republic of China and for such internal control as management determines is necessary to enable the preparation of consolidated financial statements that are free from material misstatement, whether due to fraud or error.

In preparing the consolidated financial statements, management is responsible for assessing the ability to continue as a going concern of the Company and its subsidiaries, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless management either intends to liquidate the Company and its subsidiaries or to cease operations, or has no realistic alternative but to do so.

Those charged with governance, including audit committee, are responsible for overseeing the financial reporting process of the Company and its subsidiaries.

Auditors’ Responsibilities for the Audit of the Consolidated Financial Statements

Our objectives are to obtain reasonable assurance about whether the consolidated financial statements as a whole are free from material misstatement, whether due to fraud or error, and to issue an auditors’ report that includes our opinion. Reasonable assurance is a high level of assurance, but is not a guarantee that an audit conducted in accordance with auditing standards will always detect a material misstatement when it exists. Misstatements can arise from fraud or error and are considered material if, individually or in the aggregate, they could reasonably be expected to influence the economic decisions of users taken on the basis of these consolidated financial statements.

As part of an audit in accordance with the Standards on Auditing of the Republic of China, we exercise professional judgment and professional skepticism throughout the audit. We also:

Identify and assess the risks of material misstatement of the consolidated financial statements, whether due to fraud or error, design and perform audit procedures responsive to those risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for our opinion. The risk of not detecting a material misstatement resulting from fraud is higher than for one resulting from error, as fraud may involve collusion, forgery, intentional omissions, misrepresentations, or the override of internal control.
Obtain an understanding of internal control relevant to the audit in order to design audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the internal control of the Company and its subsidiaries.
Evaluate the appropriateness of accounting policies used and the reasonableness of accounting estimates and related disclosures made by management.
Conclude on the appropriateness of management’s use of the going concern basis of accounting and, based on the audit evidence obtained, whether a material uncertainty exists related to events or conditions that may cast significant doubt on the ability to continue as a going concern of the Company and its subsidiaries. If we conclude that a material uncertainty exists, we are required to draw attention in our auditors’ report to the related disclosures in the consolidated financial statements or, if such disclosures are inadequate, to modify our opinion. Our conclusions are based on the audit evidence obtained up to the date of our auditors’ report. However, future events or conditions may cause the Company and its subsidiaries to cease to continue as a going concern.
Evaluate the overall presentation, structure and content of the consolidated financial statements, including the accompanying notes, and whether the consolidated financial statements represent the underlying transactions and events in a manner that achieves fair presentation.

Obtain sufficient appropriate audit evidence regarding the financial information of the entities or business activities within the Company and its subsidiaries to express an opinion on the consolidated financial statements. We are responsible for the direction, supervision and performance of the group audit. We remain solely responsible for our audit opinion.

We communicate with those charged with governance regarding, among other matters, the planned scope and timing of the audit and significant audit findings, including any significant deficiencies in internal control that we identify during our audit.

We also provide those charged with governance with a statement that we have complied with relevant ethical requirements regarding independence, and to communicate with them all relationships and other matters that may reasonably be thought to bear on our independence, and where applicable, related safeguards.

From the matters communicated with those charged with governance, we determine those matters that were of most significance in the audit of 2025 consolidated financial statements and are therefore the key audit matters. We describe these matters in our auditors’ report unless law or regulation precludes public disclosure about the matter or when, in extremely rare circumstances, we determine that a matter should not be communicated in our report because the adverse consequences of doing so would reasonably be expected to outweigh the public interest benefits of such communication.

We have audited and expressed an unqualified opinion including an Other Matter Paragraph on the parent company only financial statements of the Company as of and for the years ended December 31, 2025 and 2024.

However, when the attending shareholders do not represent a majority of the total number of issued shares, the Chair may announce a postponement, provided that no more than two such postponements, for a combined total of no more than 1 hour, may be made. If the quorum is not met after two postponements and the attending shareholders still represent less than one third of the total number of issued shares, the Chair shall declare the

meeting adjourned.

The relevant proposals (including extraordinary motions and amendment to original proposals) shall be decided by voting on a case-by-case basis. The meeting shall proceed in the order set by the agenda, which may not be changed without a resolution of the shareholders’ meeting.

would prejudice the interests of the Company, that shareholder may not vote on that item, and may not exercise voting rights as proxy for any other shareholder.

When voting rights are exercised in writing or by way of electronic transmission, the method for exercising the voting rights shall be specified in the shareholders’ meeting notice. A shareholder exercising voting rights in writing or by way of electronic transmission will be deemed to have attended the meeting in person, but to have waived his/her rights with respect to the extraordinary motions and amendments to original proposals of that meeting.

A shareholder intending to exercise voting rights in writing or by way of electronic transmission under the preceding paragraph shall deliver a written declaration of intent to the

Company no later than 2 days prior to the scheduled shareholders’ meeting date. When duplicate declarations of intent are delivered, the one received earliest by the Company shall prevail, except when a declaration is made to revoke the earlier declaration of intention.

After a shareholder has exercised voting rights in writing or by way of electronic transmission, in the event the shareholder intends to attend the shareholders’ meeting in person, a written declaration of intent to rescind the voting rights already exercised under the preceding paragraph shall be made known to the Company, by the same means by which the voting rights were exercised, no later than 2 days prior to the scheduled shareholders’ meeting date. If the notice of rescission is submitted after that time, the voting rights already exercised in writing or by way of electronic transmission shall prevail. When a shareholder has exercised voting rights both in writing or by way of electronic transmission and by appointing a proxy to attend a shareholders’ meeting, the voting rights exercised by the proxy in the meeting shall prevail.

Except as otherwise provided in the Company Act and in the Company's Articles of Incorporation, the adoption of a proposal shall require an affirmative vote of a majority of the voting rights represented by the attending shareholders. At the time of a vote, for each proposal, the Chair or a person designated by the Chair shall announce the total number of voting rights represented by the attending shareholders, followed by a poll of the shareholders. After the conclusion of the meeting, on the same day it is held, the results for each proposal, based on the numbers of votes for and against and the number of abstentions, shall be entered into the MOPS.

When there is an amendment or an alternative to a proposal, the Chair shall present the amended or alternative proposal together with the original proposal and decide the order in which they will be put to a vote. When any one among them is passed, the other proposals will then be deemed rejected, and no further voting shall be required.

In addition to the proposals on the meeting agenda, when a shareholder wishes to propose an extraordinary motion, the shareholder's voting rights shall represent at least 1% or more of the Company's total issued shares.

Vote monitoring and counting personnel for the voting on a proposal shall be appointed by the Chair, provided that all monitoring personnel shall be shareholders of the Company.

Article 14: The election of directors at a shareholders’ meeting shall be held in accordance with the applicable election and appointment rules adopted by the Company, and the voting results shall be announced on-site immediately, including the names of those elected and not elected as directors and the numbers of votes with which they were elected and not elected.. The ballots for the election referred to in the preceding paragraph shall be sealed with the signatures of the monitoring personnel and kept in proper custody for at least 1 year. If, however, a shareholder files a lawsuit pursuant to Article 189 of the Company Act, the ballots shall be retained until the conclusion of the litigation.
Article 15: Matters relating to the resolutions of a shareholders’ meeting shall be recorded in the meeting minutes. The meeting minutes shall be signed or sealed by the Chair of the meeting and a copy distributed to each shareholder within 20 days after the conclusion of the meeting. The meeting minutes may be produced and distributed in electronic form.
The Company may distribute the meeting minutes of the preceding paragraph by means of a public announcement made through the MOPS.

The meeting minutes shall accurately record the year, month, day, and place of the meeting, the Chair's full name, the

methods by which resolutions were adopted, and a summary of the deliberations and their results (including the weight of the votes), and the number of weighted votes each candidate received in case of a Directors' elections, and shall be retained for the duration of the existence of the Company.
