Data I/O Corporation Added to the Russell Microcap® Index

Redmond, WA, Wednesday, July 5, 2017 – Data I/O Corporation (NASDAQ: DAIO), the leading global provider of advanced data and security programming and IP management solutions for flash-memory, flash based microcontrollers and other intelligent devices, today announced that it has been added to the Russell Microcap^® Index, effective as of the close of the market on Friday, June 23, 2017, following Russell's annual reconstitution of its comprehensive set of U.S. and global equity indexes.

Membership in the Russell Microcap Index is based on market capitalization and means automatic inclusion in the appropriate growth and value style indexes.  Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies.  Approximately $8.5 trillion in assets are benchmarked against the Russell US Indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes. The Russell Microcap Index represents 2,000 small cap and microcap stocks and captures the smallest 1,000 companies in the Russell 2000, in addition to 1,000 smaller U.S.-based listed stocks.  Membership in the Russell Microcap® Index remains in place for one year and is evaluated annually.

“We are pleased that Data I/O has been added to the Russell Microcap Index,” said Anthony Ambrose, the Company’s President and CEO. "Inclusion in the index reflects the increase in our market value from our 4 consecutive years of revenue growth and will help to enhance awareness in the investment community of Data I/O as the leading global provider of Managed and Secure Programming technology.”
