Vancouver, October 8, 2025 - First Majestic Silver Corp. (NYSE: AG) (TSX: AG) (FSE: FMV) (the "Company" or "First Majestic") announces that total production in the third quarter of 2025 from the Company's four producing underground mines in Mexico, namely the Los Gatos Silver Mine (the Company holds a 70% interest in the Los Gatos Joint Venture that owns the mine), the Santa Elena Silver/Gold Mine, the San Dimas Silver/Gold Mine, and the La Encantada Silver Mine reached 7.7 million attributable silver equivalent ("AgEq") ounces, consisting of 3.9 million silver ounces, 35,681 gold ounces, 13.9 million pounds of zinc and 7.7 million pounds of lead.

"First Majestic continues to execute on the plans we have set out for 2025," said Keith Neumeyer, President & CEO. "The third quarter delivered another strong operational performance, marking the highest quarterly silver production in the Company's history and reflecting continued operational improvements and discipline across our sites. The integration of Los Gatos is nearly complete, with many of our systems and internal controls now fully implemented, enabling greater alignment and synchronization across the portfolio. During the quarter, we also reported positive exploration results at both San Dimas and Los Gatos. Silver and gold production are tracking at or above guidance. While record silver production and higher silver prices are positively impacting economics, the higher silver price has also reduced our reported silver-equivalent production by approximately 400,000 ounces when compared to metal prices used in our guidance."

Q3 2025 PRODUCTION HIGHLIGHTS

• Record Quarterly Silver Production (+96% Y/Y): The Company produced 3.9 million silver ounces in Q3 2025 representing a 96% increase when compared to 2.0 million silver ounces produced in Q3 2024. Total silver production in the quarter included 1.4 million ounces of attributable silver production from Los Gatos.

• Strong Silver Equivalent Production (+39% Y/Y): The Company produced 7.7 million AgEq ounces in Q3 2025 (8.1 million using 2025 guidance metal prices), representing a 39% increase compared to 5.5 million AgEq ounces produced in Q3 2024. This growth was primarily driven by a 96% increase in attributable consolidated silver production, including contributions from Los Gatos, as well as a 27% production increase at San Dimas.

• Continued Active Exploration Program: During the third quarter, the Company completed a total of 79,481 metres ("m") of drilling across its mines in Mexico and the United States. Throughout the quarter, up to 30 drill rigs were active consisting of five rigs at Los Gatos, eight rigs at Santa Elena, 13 rigs at San Dimas, two rigs at La Encantada and two rigs at Jerritt Canyon.

• Positive Exploration Results: In August, the Company announced positive exploration results from numerous veins at San Dimas including near-mine extensions at Elia, Sinaloa, Roberta, and Santa Teresa as well as a new high-grade silver and gold intercept of the Coronado vein in the West Block. At Los Gatos, expansionary drilling intersected significant silver and base metal mineralization in the South-East Deeps, Central Deeps, and North-West Deeps zones in results announced in September. Additional results from this year's extensive exploration drilling programs, including those at Santa Elena and at Jerritt Canyon in Nevada, are expected to be announced before year-end.

• Strong Safety Performance Continues: The Q3 2025 year to date consolidated Total Reportable Incident Frequency Rate ("TRIFR") was 0.61, below the Company's 2025 target KPI of 0.70. The Lost Time Incident Frequency Rate ("LTIFR") was 0.13, the same as it was in the same period last year. As a result of the Company's continued industry leading safety efforts, Santa Elena was recognized for "Excellence in Safety" by the Mexican Mining Chamber, in the Underground Mining category with more than 500 workers.

• Sustainability Practices Recognized: As of September 2025, the Company achieved a 30.0 ESG risk rating with Sustainalytics, a leading sustainability research and ratings firm. This score places First Majestic in the Medium risk category for the first time in the history of Sustainalytics' coverage of the Company, reflecting strong environmental and social risk management practices.

Attributable Consolidated Production Details:

1. Consolidated production values include attributable ounces from the Los Gatos Silver Mine (70%) from January 16, 2025 onwards.

Q3 2025 Mine-by-Mine Production Details:

1. Certain amounts shown in this table may not add exactly to the total amount due to rounding differences.
2. The metal prices that were used to calculate the silver equivalent ounces were silver: $39.57/oz, gold: $3,453/oz, lead: $0.89/lb.; zinc: $1.28/lb., and copper: $4.44/lb.
3. Silver equivalent ounces for the Los Gatos Silver Mine include 13,894,548 lbs. zinc and 7,653,733 lbs. lead (70% attributable basis) and 19,849,354 lbs. zinc and 10,933,904 lbs. lead (100% basis).

Los Gatos Silver Mine (reported on a 70% attributable basis):

• During the third quarter, Los Gatos produced 2,125,666 attributable AgEq ounces, consisting of 1,408,467 ounces of silver, 13,894,548 pounds of zinc, 7,653,733 pounds of lead, and 727 ounces of gold. Production at Los Gatos was impacted by lower mining rates at the beginning of the quarter due to an increase in mobile equipment maintenance which resulted in lower equipment availability. However, mining rates normalized throughout the quarter and the Company expects to continue strong production throughout the remainder of the year to meet its updated 2025 guidance.

• The mill processed a total of 213,262 tonnes of ore, with head grades of 236 g/t silver, 4.12% zinc, 1.89% lead, and 0.22 g/t gold. Management continues to focus on achieving a sustainably higher mill throughput at Los Gatos by increasing mining rates. In line with the updated 2025 guidance, the Company is finalizing the selection of a new development contractor to increase development rates at the mine, targeting a sustained increase in ore throughput to 4,000 tpd, based on operating days, in the second half of 2026.

• Silver, zinc, lead and gold recoveries during the quarter averaged 87%, 72%, 86% and 48%, respectively.

• During the quarter, five surface drill rigs completed 13,043 m of drilling on the property. Drilling was slightly behind plan due to drill contractor changes and the associated ramp up. Drilling continued at the South-East Deeps, Central Deeps and North-West Deeps zones, as well as at other greenfield targets.

Santa Elena Silver/Gold Mine:

• Santa Elena produced 2,256,695 AgEq ounces during the quarter, a decrease of 16% year-over-year, consisting of 412,669 ounces of silver and 20,979 ounces of gold. The decline in production was primarily due to lower grade gold ore from the Ermitaño mine, as expected under the 2025 mine plan.

• The mill processed a total of 277,858 tonnes of ore, 7% higher than the same period last year, with average silver and gold head grades of 71 g/t and 2.56 g/t, respectively. Average silver ore grades increased 6%, while gold ore grades declined 27% for the quarter.

• Silver and gold recoveries during the quarter averaged 65% and 92%, respectively, compared to 67% and 94% in the same period last year. Lower recoveries were anticipated and are a direct correlation to lower feed grades.

• During the quarter, eight drill rigs, consisting of five surface rigs and three underground rigs, completed 19,872 m of drilling on the property. Drilling focused on the newly discovered Santo Niño and Navidad resources, and the conversion of Inferred Mineral Resources to Indicated Mineral Resources at Ermitaño-Luna to support mine development planning.

San Dimas Silver/Gold Mine:

• San Dimas produced 2,690,893 AgEq ounces during the quarter representing a 27% increase compared to Q3 2024, consisting of 1,467,344 ounces of silver and 13,945 ounces of gold. Silver production increased by 40%, while gold production increased by 11%, when compared to the same period last year. The strong quarterly performance was a result of increased throughput and silver grades, partially offset by slightly lower gold grades.

• The mill processed a total of 234,156 tonnes of ore, an increase of 20% compared to Q3 2024, with average silver and gold grades of 222 g/t and 2.00 g/t, respectively, compared with 188 g/t and 2.12 g/t, respectively, in the same period last year. Higher throughput was driven by increased mining rates, which also enabled the buildup of an ore stockpile and supported above-nameplate mill performance during the quarter.

• Silver and gold recoveries during the quarter averaged 88% and 92%, respectively, compared to 89% and 95%, respectively, in the same period last year.

• During the quarter, a total of 13 drill rigs consisting of two surface rigs and 11 underground rigs completed 32,289 m of drilling on the property. Drilling was slightly ahead of plan.

La Encantada Silver Mine:

• During the quarter, La Encantada produced 575,193 ounces of silver, representing a 6% increase compared to Q3 2024, driven primarily by a 22% increase in ore processed, partially offset by lower silver grades and a 5% decrease in silver recovery. Production at La Encantada was impacted by lower ore grades as mine development activities were behind plan due to difficult ground conditions. A mining contractor was engaged to accelerate mine development, and as a result, ore flow and development rates have increased to targeted levels. Silver production returned to budgeted levels by the end of Q3 2025.

• The mill processed a total of 271,726 tonnes of ore, a 22% increase over the same period last year, with an average silver grade of 100 g/t, compared to 110 g/t in the same period last year.

• Silver recovery for the quarter was 66%, compared to 69% in Q3 2024.

• During the quarter, up to two drills rigs consisting of one surface rig and one underground rig completed 1,755 m of drilling on the property. 2025 drilling is slightly behind plan, having shifted from underground to surface- focused, where the Company is currently testing a new exploration target, La Esquina.

Jerritt Canyon Gold Mine:

• During the quarter, the Company commenced its 2025 drilling program at Jerritt Canyon in Nevada, USA. Two surface drill rigs completed 12,522 m of drilling on the property. The Company plans to release results from the 2025 drilling program before the end of 2025. Drilling is focused on greenfield exploration and Mineral Resource addition and is ahead of plan.

Pursuant to the Share Repurchase Program, First Majestic may, during the 12-month period commencing October 14, 2025, and ending on or before October 13, 2026, purchase up to 24,500,000 of its common shares ("Shares"), being approximately 5% of the Company's 490,028,835 issued and outstanding Shares as of September 30, 2025. First Majestic may purchase up to a daily maximum of 402,698 Shares (being 25% of the average daily trading volume of the Shares for the last six calendar months, which was 1,610,792 Shares), subject to the TSX rules permitting block purchases.

First Majestic will make no purchases of Shares under the Share Repurchase Program other than through open-market purchases.
