⁽¹⁾ Silver equivalents for 2026 are calculated using a 90:1 Ag:Au ratio, 45 silver oz to 1 lead tonne; 61 silver oz to 1 zinc tonne; 238 silver oz to 1 copper tonne ratio. Silver equivalents for 2025 are calculated using an 80:1 Ag:Au ratio, 60 silver oz to 1 lead tonne; 85 silver oz to 1 zinc tonne; 300 silver oz to 1 copper tonne ratio.

⁽²⁾ These are non-IFRS financial measures and ratios. Further details on these non-IFRS financial measures and ratios are provided at the end of this press release and in the MD&A accompanying the Company's financial statements, which can be viewed on the Company's website, on SEDAR+ at www.sedarplus.com and on EDGAR at www.sec.gov.

Direct operating costs per tonne in Q1 2026 increased to $186.92, 31% higher than $142.72 in Q1 2025. The increase was primarily driven by the addition of Terronera and Kolpa, which had direct operating costs per tonne of $195.11 and $155.92, respectively, during Q1 2026. The disposal of Bolañitos, which had a lower direct operating cost per tonne of $102.81 in Q1 2025, also contributed to the higher consolidated average. In addition, Guanaceví experienced higher cost per tonne due to lower throughput and higher underlying direct production costs.

Consolidated cash costs per silver ounce, net of by-product credits, were $22.54 in Q1 2026, representing a 42% increase from $15.89 in Q1 2025 due to the higher metal prices causing higher royalty, third party material cost, and special mining duties. Each mine has different costs and produces different amounts of payable silver, which affect the consolidated cash cost per ounce depending on the mix of production. For the three months ended March 31, 2026, the cash costs per silver ounce were $24.52 for Kolpa, $38.59 for Guanaceví, offset by negative $2.14 for Terronera.

Consolidated All‑in Sustaining Costs ("AISC") per silver ounce in Q1 2026 were $37.03, 51% higher than $24.48 in Q1 2025. The increase was predominantly due to the contribution of Kolpa, which had AISC of $36.12 per ounce, and higher AISC of $48.47 at Guanaceví caused by the higher third-party material cost, higher royalties and special mining duties, partially offset by the contribution from Terronera, where AISC of $22.31 per ounce lowered the consolidated average. Consolidated AISC decreased from $41.19 in Q4 2025 to $37.03 in Q1 2026 primarily reflecting the ramp up of operations at Terronera and the efficiencies gained.

In Q1 2026, the Company's mine operating earnings were $93.5 million (Q1 2025 – $12.9 million), driven by operating earnings of $38.4 million from Terronera, $23.0 million from Kolpa, and $20.4 million higher operating earnings at Guanaceví, partially offset by lower operating earnings from Bolañitos following its sale on January 15, 2026. Revenue for the quarter was $209.7 million, compared to $63.5 million in Q1 2025 driven by higher metal prices and higher sales, while cost of sales increased to $116.3 million from $50.6 million, primarily due to the inclusion of revenue and costs incurred at Terronera and Kolpa.

The Company recorded operating earnings of $83.8 million in Q1 2026 (Q1 2025 – $4.1 million) after exploration expenditures of $5.0 million (Q1 2025 – $4.5 million) and general and administrative expenses of $4.7 million (Q1 2025 – $4.3 million). Exploration expenses increased due to additional expenditures on advancing Pitarrilla and exploration work at Kolpa, partially offset by lower exploration spending at Terronera.

Earnings before taxes for Q1 2026 were $85.9 million, compared to a loss of $27.7 million in Q1 2025. This was after a loss on derivative contract revaluations of $24.2 million, a foreign exchange loss of $0.3 million, investment and other income loss of $3.2 million, and finance costs of $5.8 million, partially offset by a gain on the sale of Bolañitos of $35.6 million.

The Company recorded net earnings of $64.9 million for Q1 2026 (Q1 2025 – net loss of $32.9 million) after income tax expense of $21.0 million, which included $33.8 million of current tax expense and a deferred tax recovery of $12.8 million, primarily arising from temporary differences related to the buildup of finished goods inventory.

This news release should be read in conjunction with the Company's condensed consolidated interim financial statements for the period ended March 31, 2026, and associated Management's Discussion and Analysis ("MD&A") which are available on the Company's website, www.edrsilver.com, on SEDAR+ at www.sedarplus.com and on EDGAR at www.sec.gov.

Such forward-looking statements and information herein include but are not limited to statements regarding expected operating and efficiency improvements, the Company's strategic objectives, areas of priority, ability to meet production goals, expectations of throughput at Kolpa, the planned allocation of resources, Endeavour's ability to unlock value across the Company's development pipeline and deliver long-term value for its stakeholders, and the timing and results of various activities. The Company does not intend to and does not assume any obligation to update such forward-looking statements or information, other than as required by applicable law.

Forward-looking statements or information involve known and unknown risks, uncertainties and other factors that may cause the actual results, level of activity, production levels, performance or achievements of Endeavour and its operations to be materially different from those expressed or implied by such statements. Such factors include but are not limited to unexpected changes in production and costs guidance; the ongoing effects of inflation and supply chain issues on mine economics; fluctuations in the prices of silver and gold; fluctuations in the currency markets (particularly the Mexican peso, Peruvian sol, Canadian dollar, Chilean peso, and U.S. dollar); fluctuations in interest rates; effects of inflation; changes in national and local governments, legislation, taxation, controls, regulations and political or economic developments in Canada, Peru and Mexico; operating or technical difficulties in mineral exploration, development and mining activities; risks and hazards of mineral exploration, development and mining (including, but not limited to, environmental hazards, industrial accidents, unusual or unexpected geological conditions, pressures, cave-ins and flooding); inadequate insurance, or inability to obtain insurance; availability of and costs associated with mining inputs and labour; the speculative nature of mineral exploration and development; diminishing quantities or grades of mineral reserves as properties are mined; risks in obtaining necessary licenses and permits; and challenges to the Company's title to properties; as well as those factors described in the section "risk factors" contained in the Company's most recent form 40F/Annual Information Form filed with the S.E.C. and Canadian securities regulatory authorities.

Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in forward-looking statements or information, there may be other factors that cause results to be materially different from those anticipated, described, estimated, assessed or intended. There can be no assurance that any forward-looking statements or information will prove to be accurate as actual results and future events could differ materially from those anticipated in such statements or information. Accordingly, readers should not place undue reliance on forward-looking statements or information.
