Sterling Construction Company, Inc Set to Join Russell 3000® Index

Sterling Construction Company, Inc. (NasdaqGS: STRL) (“Sterling” or “the Company”) is set to join the broad-market Russell 3000® Index at the conclusion of the Russell indexes’ annual reconstitution, effective after the US market opens on June 26th, according to a preliminary list of additions posted June 9th.

Annual reconstitution of the Russell US indexes captures the 4,000 largest US stocks as of the end of May, ranking them by total market capitalization. Membership in the US all-cap Russell 3000® Index, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000® Index or small-cap Russell 2000® Index as well as the appropriate growth and value style indexes. FTSE Russell determines membership for its Russell indexes by objective, market-capitalization rankings and style attributes.

“We are extremely pleased to be added to the Russell 3000® Index to raise Sterling Construction’s profile and visibility within the investment community,” said Joseph Cutillo, Chief Executive Officer. “While our turnaround efforts continue, our return to the Russell indexes is indicative of the great progress we’ve made in executing our strategic plan. We look forward to the opportunity to articulate our story to a broader shareholder base.”

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for active investment strategies. Approximately $8.4 trillion in assets are benchmarked against Russell’s US indexes. Russell indexes are part of FTSE Russell, a leading global index provider.
