Unaudited interim results for the three-and six-month periods ended 30 June 2026

Unaudited interim results for the three-and six-month periods ended 30 June 2026 Serabi (AIM:SRB, TSX:SBI, OTCQX:SRBIF), the Brazilian focused gold mining and development company, is pleased to release its unaudited interim results for the three- and six-month periods ended 30 June 2026 (all currency amounts are expressed in US Dollars unless otherwise stated). HIGHLIGHTS Gold sales for the first half of 2026 of 21,348 ounces (corresponding six-month period of 2025: 20,215 ounces). Gold production for the first half of 2026 of 23,049 ounces (corresponding six-month period of 2025: 20,545 ounces). Cash held at 30 June 2026 of $65.7 million (31 December 2025: $49.2 million). Company remains debt free; repaid $5.3 million to Banco Santander in Brazil during Q1-2026. EBITDA for the six-month period of $44.4 million (corresponding six-month period of 2025: $26.3 million). Profit after taxation for the six-month period of $30.1 million (corresponding six-month period of 2025: $18.9 million). Earnings per share of 39.71 cents (corresponding six-month period of 2025: 24.99 cents). Net cash inflow from operations for the six-month period (after mine development expenditure of $5.3 million) of $34.8 million (corresponding six-month period of 2025: $19.1 million inflow, after mine development expenditure of $2.7 million). Average gold price of $4,687 per ounce received on gold sales during the six-month period (corresponding six-month period of 2025: $3,093). Cash Cost for the six-month period to 30 June 2026 of $2,010 per ounce (corresponding six-month period of 2025: $1,379 per ounce). All-In Sustaining Cost for the six-month period to 30 June 2026 of $2,682 per ounce (corresponding six-month period of 2025: $1,792 per ounce). Superintendência do Desenvolvimento da Amazônia ("SUDAM") has formally approved the renewal of the Corporate Income Tax (IRPJ) reduction incentive for the Palito Gold Complex ("Palito"), located in Pará State, Brazil. With this approval, the Brazilian nominal corporate income tax rate applicable to Palito will be maintained at approximately 15.25% (reduced from 34%), extending the benefit for an additional 10 years, through 2035. The full interim statements together with commentary can be accessed on the Company’s website using the following LINK. Mike Hodgson, CEO of Serabi, commented Gold sales for the first half of 2026 totalled 21,348 ounces, representing a 6% increase on the same period in 2025. Whilst this operational performance was in-line with budget, when combined with an average realised gold price of $4,687 per ounce, resulted in EBITDA of $44.4 million for the period, a 69% increase over the same period a year ago. Serabi ended the period with a cash balance of $65.7 million, an increase from $49.2 million at the end of Q4-2025. For the 6 month period, cash flow from operations of $40.1 million was offset by cash flow from investing activities of $(18.8) million as well as cash flow from financing activities of $(5.5) million. Factors impacting the cash generated for Q2-2026 were the lower realised gold prices in Q2 of $4,490 per ounce (vs Q1-2026 of $4,926 ounce), development of the Galena and Serra South zones at Coringa, and approximately $4 million of one-time G&A charges. With brownfield exploration activity continuing in 2026 with another 30,000m drill programme underway across both Palito Complex and Coringa, the Company is positioning itself for future resource growth and long-term value creation. The balance sheet remains debt free as the debt with Banco Santander was repaid in Q1-2026. Cash Cost of $2,010 and AISC of $2,682 are higher than Q1-2026, largely driven by the continued ramp up at Coringa and the one-time G&A charges. With the Meio zone now at commercial production, costs associated with mining the Meio zone are included in cash cost and AISC. As the Company reported in the Q2-2026 operational update, production guidance is set at 53,000 plus ounces of gold. This target has been based on one of either of two assumptions. Firstly, the GUIA licence issued for Coringa from the ANM (Ministry of Mines) under which the Company is currently permitted to transport annually 100,000 tonnes of ore to Palito was to be increased to 200,000 tonnes. Alternatively, the guidance target also assumed receipt of the full mining concession by Q4-2026, thereby lifting all tonnage constraints at Coringa. In both scenarios, the Company would be able to transport much greater volumes of ore in Q4-2026 and utilise the soon to be commissioned fourth ball mill at Palito.   With respect to the GUIA licence, the Company is continuing production at Coringa under the current 3-year GUIA licence of 100,000 tonnes annually which as previously reported, expires on 29 January 2027, or earlier if the annual limit of tonnage is exceeded. The Board of Serabi is currently confident that the GUIA term will either be extended and / or the annual tonnage limit extended shortly by the ANM to avoid any temporary production interruption at Coringa in Q4-2026. The Company is making highly encouraging progress with the ANM to achieve this, although there is obviously no certainty yet on timing and a further update will be provided in mid-October in our Q3-2026 operational release. With respect to the Full Mining Concession, the two fundamental approvals required are in their final stages. The approval of the Indigenous Component Study (ECI) is now very close, and it only remains for the Federal Agency for Indigenous Lands (FUNAI) Board of Directors to approve the study. The FUNAI Legal and Technical departments are recommending approval. We still anticipate this happening in Q4-2026. In addition, the approval for the change of land use from Agriculture to Mineral Exploitation by the Land Registry (INCRA) is also now in its final stages, which has been technically and legally approved. The final steps are for the Directors of INCRA to approve at the Board level of INCRA. The Board of Serabi also anticipates this happening in Q4-2026. Once these two approvals from FUNAI and INCRA are received, SEMAS can issue Serabi with an Operating Licence.” Overview of the financial results In the first half of 2026, the Group has reported revenue and operating costs related to the sale of 21,348 ounces in the period. This compares to sales of 20,515 ounces in the first half of 2025. Reported revenues and costs reflect the ounces sold in each period and as a result total costs for the six-month period are higher than for the corresponding period of 2025. On 16 January 2026, the Group fully repaid the Banco Santander short-term working capital facility which the Group had previously entered into on 22 January 2025. As a result, at the time of writing, the Group is debt free.

Basis of preparation These interim condensed consolidated financial statements are for the three and six-month periods ended 30 June 2026. Comparative information has been provided for the unaudited three and six-month periods ended 30 June 2025 and, where applicable, the audited twelve-month period from 1 January 2025 to 31 December 2025. These condensed consolidated financial statements do not include all the disclosures that would otherwise be required in a complete set of financial statements and should be read in conjunction with the 2025 annual report. The condensed consolidated financial statements for the periods have been prepared in accordance with International Accounting Standard 34 “Interim Financial Reporting” and the accounting policies are consistent with those of the annual financial statements for the year ended 31 December 2025 and those envisaged for the financial statements for the year ending 31 December 2026. The interim financial information has not been audited and does not constitute statutory accounts as defined in Section 434 of the Companies Act 2006. Whilst the financial information included in this announcement has been compiled in accordance with International Financial Reporting Standards (“IFRS”) this announcement itself does not contain sufficient financial information to comply with IFRS. The Group statutory accounts for the year ended 31 December 2025 prepared in accordance with international accounting standards in conformity with the requirements of the Companies Act 2006 have been filed with the Registrar of Companies. The auditor’s report on these accounts was unqualified. The auditor’s report did not contain a statement under Section 498 (2) or 498 (3) of the Companies Act 2006. The interim condensed consolidated financial statements are presented in thousands of US Dollars, unless otherwise stated. Accounting standards, amendments and interpretations effective in 2025 The Group has not adopted any standards or amendments in advance of their effective date. The following new amendment has been issued by the IASB and is effective for annual periods beginning on or after 1 January 2026: Classification and Measurement of Financial Instruments – Amendments to IFRS 7 and IFRS 9 1 January 2026 Contracts Referencing Nature-dependent Electricity – Amendments to IFRS 7 and IFRS 9 1 January 2026 Annual Improvements to IFRS Accounting Standards – Volume 11 1 January 2026 No other standards or amendments are expected to be effective in 2026. Certain new accounting standards and interpretations have been published that are not mandatory for the current period and have not been early adopted. These standards are not expected to have a material impact on the Company’s current or future reporting periods. These financial statements do not constitute statutory accounts as defined in Section 434 of the Companies Act 2006. (i)      Going concern At 30 June 2026 the Group held cash of US$65,689k which represents an increase of US$16,466k compared to 31 December 2025. On 16 January 2026, the Group fully repaid the Banco Santander short-term working capital loan plus interest which the Group had previously entered on 22 January 2025. As a result, at the time of writing, the Group is debt free. Management prepares, for Board review, regular updates of its operational plans and cash flow forecasts based on their best judgement of the expected operational performance of the Group and using economic assumptions that the Directors consider are reasonable in the current global economic climate. The current plans assume that during 2026 the Group will continue gold production from its Palito Complex operation and current production from the Coringa mine without interruption, assuming that the GUIA licence issued for Coringa from the ANM (Ministry of Mines) under which the Company is currently permitted to transport annually 100,000 tonnes of ore to Palito is increased to 200,000 tonnes or receipt of the full mining concession by Q4-2026, thereby lifting all tonnage constraints at Coringa. Even if neither of these scenarios eventuate, and production is suspended at Coringa, cash flow forecasts show adequate resources to continue in operational existence for the foreseeable future. The Directors will limit the Group’s discretionary expenditures, when necessary, to manage the Group’s liquidity. The Directors acknowledge that the Group remains subject to operational and economic risks and any unplanned interruption or reduction in gold production or unforeseen changes in economic assumptions may adversely affect the level of free cash flow that the Group can generate on a monthly basis. The Directors have a reasonable expectation that, after taking into account reasonably possible changes in trading performance, and the current macroeconomic situation, the Group has adequate resources to continue in operational existence for the foreseeable future.
