Rhea-AI Summary

Knife River Corporation reported a larger seasonal loss but higher sales for the quarter ended March 31, 2026. Revenue rose to $410.1 million from $353.5 million, driven mainly by higher ready-mix concrete and aggregate volumes, including contributions from 2025 and 2026 acquisitions.

The company posted a net loss of $79.2 million, compared with a loss of $68.7 million a year earlier, with basic and diluted loss per share of $1.40. EBITDA improved to a loss of $35.4 million from a loss of $41.5 million as gross loss narrowed and cost controls helped offset higher interest expense.

Knife River continued its growth strategy, spending $174.2 million on three Mountain-region acquisitions and funding seasonal working capital and deals with a new $270 million borrowing under its revolving credit facility. Contracting backlog reached $1.17 billion, with about $914 million expected to convert to revenue within 12 months, supported by strong public infrastructure funding in its 15-state footprint.
