Hecla Mining Company to Join S&P MidCap 400 Index

Key Terms

s&p midcap 400 index financial

An index that tracks the stock performance of 400 medium-sized publicly traded U.S. companies chosen for size and trading activity, serving as a snapshot of the mid-cap segment of the market. Think of it as a basket representing the health and returns of mid-sized firms; investors use it as a benchmark to compare funds, build diversified portfolios, and gauge how that slice of the economy is performing compared with small or large companies.

index funds financial

A fund that pools investors’ money to buy the same collection of stocks or bonds that make up a market index — like a ready-made basket representing the whole market or a specific slice of it. It matters because it gives broad exposure with lower fees and simpler management than picking individual securities, reducing the impact of any single holding and making it efficient for long-term investing.

COEUR D'ALENE, Idaho--(BUSINESS WIRE)-- Hecla Mining Company (NYSE: HL) today announced that it will be added to the S&P MidCap 400 Index, effective prior to the open of trading on December 22, 2025, according to an announcement by S&P Dow Jones Indices.

Inclusion in the S&P MidCap 400 reflects Hecla’s strong performance, operational scale, and consistent execution across its portfolio of silver and gold operations in the United States and Canada. The S&P MidCap 400 is designed to measure the performance of a subset of U.S. equities with market caps between $8.0 billion and $22.7 billion, and Hecla’s addition underscores the Company’s increasing recognition within the investment community. Inclusion is not based solely on empirical measures, rather, it also includes subjective analysis by S&P’s Index Committee.

Hecla's inclusion in the S&P MidCap 400 Index reflects a disciplined evaluation by the S&P Index Committee, which is noted by S&P as involving careful consideration, and not only market capitalization and other objective criteria, in its selection process. In evaluating companies for inclusion, the committee weighs multiple factors including sector representation, corporate governance standards, and market stability—exercising the discretion necessary to maintain the integrity and quality of the index. This recognition underscores Hecla's strong operational execution, disciplined capital allocation, and solid governance practices that align with the standards of a quality mid-cap company.

"Our addition to the S&P MidCap 400 reflects the significant progress we've made in building a world-class silver-focused mining company," said Rob Krcmarov, President and CEO. "The fact that the S&P Index Committee used its discretion to include Hecla as the only precious metals producer in the index speaks to our upward trajectory. The recognition validates our disciplined capital allocation and operational excellence across our U.S. and Canadian platform. We believe inclusion in the Index, and the related expanded institutional investor base, positions Hecla well to drive sustainable value creation for our shareholders and stakeholders."

The S&P MidCap 400 is widely followed by index funds and institutional investors, and Hecla’s inclusion is expected to broaden its shareholder base and enhance trading liquidity.
