Distribution Solutions Group — the parent of Lawson Products and Gexpro Services — reported revenue increased 3.8% to $496 million in the first quarter. Organic sales rose 3.6% over that span.

However, operating income plunged 32.2% to $13.6 million, while net income plummeted by 88.3% to around $382,000.

DSG officials said that the company had anticipated “some margin pressures” in the quarter, and added that fewer selling days and “certain timing and isolated expenses” further eroded its adjusted EBITDA margin.

The Lawson segment saw $123.7 million in Q1 revenue, up from $120.5 million last year, but its operating income dropped by more than half to just over $3 million.
