Endeavour Silver Rides Record Output Amid Rising Costs

Endeavour Silver ((TSE:EDR)) has held its Q1 earnings call. Read on for the main highlights of the call.

Endeavour Silver’s latest earnings call painted a picture of robust growth tempered by rising costs and operational risks. Management emphasized record production, sharply higher cash flow and a fortified balance sheet, while acknowledging inflationary pressures, labor challenges and permitting uncertainties. Investors heard a confident but cautious tone as the company prioritizes growth projects over near-term shareholder payouts.

Record Production and Silver Equivalent Growth

Endeavour Silver reported a step change in output, producing nearly 2.0 million ounces of silver and 12,000 ounces of gold in the first quarter of 2026. That translated into about 3.0 million silver-equivalent ounces, marking a 78% increase versus the same period last year, largely driven by the additions of Copa and Terronera to the portfolio.

Revenue and Operating Cash Flow Strength

The production surge flowed directly into the top line, with revenue climbing 23% year over year to $210 million in the quarter. Profitability at the mine level improved even faster, as mine operating cash flow before taxes jumped 400% to $115 million and mine operating earnings reached $94 million.

Adjusted Profitability

Earnings quality appeared solid, with management highlighting adjusted net earnings of $59 million in the quarter. On a per-share basis, adjusted earnings came in at $0.21, underscoring that the company is translating higher production and revenue into tangible bottom-line gains.

Low All-in Sustaining Cost This Quarter (with context)

All-in sustaining costs, net of byproduct credits, were reported at $37 per ounce in the first quarter of 2026. While this level is higher than a year ago, it represented a 9% improvement from the fourth quarter of 2025 as Terronera ramped up and operational efficiencies began to take hold across the asset base.

Strong Balance Sheet and Liquidity

The company’s financial position remains a central pillar of its growth strategy, with a cash balance exceeding $232 million as of March 31, 2026. Working capital stood above $173 million, giving Endeavour Silver ample flexibility to fund development projects and navigate volatility without stretching its balance sheet.

Copa Plant Capacity Expansion Commissioned

At Copa, a key growth asset, management has completed a major plant expansion by installing a new three-stage crusher and ball mill. These upgrades have lifted processing capacity to more than 2,500 tonnes per day and are expected to drive unit cost benefits through 2026 as one-time expansion spending rolls off.

Terronera and Guanacevi Operational Momentum

Terronera is operating near design expectations, with the company reporting steady improvement in metrics, a resumption of exploration and plans to transition to LNG power to enhance efficiency. Legacy mine Guanacevi continued to be a cash generator, delivering cash flows above $20 million in the quarter while step-out drilling aims to extend mine life and resource potential.

Pitarrilla Project Advancement

Endeavour Silver is steadily advancing its large-scale Pitarrilla project through ongoing exploration and technical studies. Management signaled that an economic evaluation is expected in the third quarter of 2026, with preparations underway for a potential construction start in 2027 and an estimated build cost in the range of $500 million to $600 million.

Higher All-in Sustaining Costs YoY

Despite quarter-on-quarter improvements, the company’s all-in sustaining costs were up 51% compared with the first quarter of 2025. The higher figure reflects the inclusion of new, higher-cost operations like Copa and Terronera, which are still in the early stages of optimization and currently inflate the consolidated cost profile.

Elevated Direct Operating and Per-Tonne Costs

Direct operating cost per tonne increased roughly 30% year over year in the first quarter as the new mines were incorporated into the portfolio. Management also noted that direct costs per tonne, a metric that includes royalties and third-party ore purchases, remained elevated in the period, underscoring near-term margin pressure from higher operating inputs.

Cost Sensitivity to Metal Prices

The company highlighted how sensitive its cost metrics are to changes in metal prices, since certain costs are indexed to realized prices. For example, a one-dollar increase in silver prices raises cost per tonne by about $0.90 at Terronera, $3.80 at Guanacevi and $0.50 at Copa, leaving the business more exposed to price swings than headline cost figures might suggest.

Operational and Labor Pressures in Peru

Operations in Peru are facing a tight labor market, complicating efforts to attract and retain skilled workers and pushing up labor and training costs. Management warned that these conditions are also weighing on efficiency and are likely to persist in the near term, adding another layer of cost pressure in the region.

Early-Stage/One-Time Costs at Terronera

Terronera remains in the early stages of its operating life, and ramp-up dynamics are still driving one-time capital and elevated operating expenses. The company expects these temporary costs to moderate as throughput stabilizes, but investors should anticipate continued near-term cost pressure until the mine reaches steady-state performance.

Permitting and Timing Risk for Pitarrilla

The development timeline for Pitarrilla carries notable permitting risk, particularly around the tailings storage facility that sits on the project’s critical path. Management acknowledged that some permit timelines have already slipped and that delays in securing tailings approvals could push construction beyond current expectations, potentially reshaping the project schedule.

Security-Related Disruption to Operations

Endeavour Silver also faced security-related challenges when regional cartel-linked blockades disrupted logistics in February. The company temporarily shut operations for three days to protect employees, highlighting the geopolitical and operational risks that can impact production even at otherwise well-performing assets.

Forward-Looking Guidance and Outlook

Looking ahead, management expects cost and grade improvements through 2026 as ramp-ups complete and one-off capital spending declines, particularly at Terronera, where grades should be slightly higher in the second quarter and show a material step-up in the second half. With $210 million in quarterly revenue, robust mine earnings, and more than $232 million in cash plus strong working capital, the company sees itself well positioned to fund growth projects like Pitarrilla while gradually lowering all-in sustaining and direct operating costs.

Endeavour Silver’s earnings call underscored a company in the midst of a major growth phase, balancing record production and expanding cash flow against rising costs and project execution risks. Investors will be watching closely to see if the promised cost improvements and grade gains materialize over the coming quarters, as the success of Copa, Terronera and eventually Pitarrilla will largely determine the sustainability of today’s growth story.
