THE WOODLANDS, TX – May 7, 2018 – Sterling Construction Company, Inc. (NasdaqGS: STRL) (“Sterling” or “the Company”) today announced financial results for the first quarter ended March 31, 2018.

•	Revenues grew 45.0% to $222.5 million compared to $153.4 million;


•	Gross margin was 9.3% of revenues compared to 6.1%;

Consolidated Financial Position at March 31, 2018:


•	Cash and Cash Equivalents were $55.5 million;


•	Working capital totaled $98.7 million; and


•	Total debt was $86.2 million.

Business Overview:

First quarter 2018 revenues increased 45.0% compared to the prior year quarter. Heavy civil construction revenues grew $33.8 million or 22.0% over the first quarter of 2017 driven by large construction projects in the Rocky Mountain region and the inclusion of the acquired Tealstone heavy civil construction revenues. First quarter 2018 residential construction revenues totaled $35.3 million. The residential markets in our primary geographies continue to see steady growth. Texas housing starts are expected to continue to grow, over 10%, in 2018, with Houston posting the most new housing starts followed by steady growth in Dallas. Our business in Dallas, which is our principal residential market, continues to outpace the overall market growth rate in the region.

Gross profit was $20.6 million in the first quarter of 2018, an increase of $11.3 million from the prior year first quarter. Gross margin expanded by 320 basis points to 9.3% reflecting significant improvement in heavy civil construction gross margin along with approximately 200 basis points of improvement attributable to the incremental benefit from the acquired residential construction business.

General and administrative expenses were $13.1 million in the first quarter of 2018, or 5.9% of revenues compared to $10.6 million or 6.9% in the first quarter of 2017.

Heavy Civil Construction Backlog Highlights:


•	Combined Backlog at March 31, 2018 was $1.04 billion, an increase from $995 million at December 31, 2017. Combined Backlog consists of $884.6 million of backlog and $150.6 million of unsigned contracts as of March 31, 2018 compared to $744.4 million and $250.2 million at December 31, 2017, respectively. No residential construction is included in backlog;


•	Combined Backlog for March 31, 2018 included $48.2 million related to our two consolidated construction joint ventures compared to $199 million at the beginning of 2017, reflecting the substantial progress on these projects. This construction joint venture reduction in backlog has essentially been replaced with new backlog with 100% Sterling participation;


•	Gross margin on projects in Combined Backlog as of March 31, 2018 averaged 8.4%, consistent with December 31, 2017; and


•	Combined Backlog is comprised of approximately 65% heavy highway construction projects with the balance of 35% consisting mainly of commercial, aviation, water containment and treatment projects.

CEO Remarks and Outlook:

“Our 2018 first quarter results represent our best financial results in almost a decade for our seasonally weakest quarter,” stated Joe Cutillo, Sterling’s Chief Executive Officer. “Sterling’s performance in the period was evidence of the profitable growth potential of the business platform we’ve developed, which is driven by our diverse construction capabilities across a footprint of attractive geographies. Our Rocky Mountain heavy civil operations once again performed extremely well, executing effectively on multiple large highway and airport projects that we were awarded over the past two years. As we anticipated, the combined backlog for our heavy civil segment grew slightly relative to the end of 2017, which is consistent with our bottom line-focused plan to selectively add projects to our pipeline that meet our stringent margin and risk criteria. This strategy has proved effective as the first quarter represented Sterling’s fourth consecutive quarter of gross margins exceeding 9.2% along with positive net income attributable to Sterling common stockholders. Our residential segment continues to contribute materially to both our revenues and profitability. The ongoing strength of the Dallas-Fort Worth housing market coupled with the beginning of our progressive expansion in Houston, makes us increasingly enthusiastic about the multi-year growth potential of our residential business. Also noteworthy is the operating leverage inherent in our business as our general and administrative expenses once again declined as a percent of revenues relative to the prior year, a trend we expect to persist through 2018 as our revenues continue to increase.”

Mr. Cutillo continued, “Based on our first quarter results, our current backlog and the macro outlook for our end markets and geographies, we reaffirm our expectations for 2018 revenues of between $1.0 billion and $1.035 billion and net income attributable to Sterling common stockholders of between $23 million and $26 million, with average common shares outstanding of 27.5 million. As previously mentioned, the first quarter is historically our seasonally weakest quarter, with the second and third representing our most active quarters. The midpoint of our guidance implies year-over-year growth in revenues of more than 6% and calls for an increase in net income in excess of 110% as compared to 2017. Our revenue expectations reflect growth in our residential business of greater than 10%, and mid-single digit growth in our heavy civil business, with our overall revenue mix continuing to migrate towards higher margin work. Our outlook does not assume any major positive changes in government investment in infrastructure, which would likely enhance our growth forecast.”
