Northwest Pipe Company Reports Strong Profitability and Backlog and

Announces Fourth Quarter Conference Call

Fourth Quarter Highlights

Full-year Highlights

VANCOUVER, Washington: Northwest Pipe Company (Nasdaq: NWPX), an industry leader of engineered pipeline systems for water infrastructure, announced today its financial results for the quarter and year ended December 31, 2019. The Company will broadcast its fourth quarter 2019 earnings conference call on Tuesday, March 3, 2020 at 7:00 am PST.

Outlook – “We concluded 2019 with a backlog that was at a year-end record of $258 million. The strong market conditions, focus on margin over volume, and cost reduction activity lead to a fourth quarter that had the highest gross margin since 2013 and a full year that had revenue and gross profit that were close to historical highs,” said Scott Montross, President and CEO of the Company. “Our acquisition of Geneva Pipe and Precast opens avenues for growth by significantly expanding the available market and by adding innovative products that are expected to provide organic growth opportunities. For the legacy Northwest Pipe business, we expect the first quarter to be affected by weather delays and jobs that are slow getting started. Revenue is projected to be in line with the first quarter of 2019 with gross margins that are four to five percentage points higher. The new Geneva plants are expected to add several million dollars in revenue.”

Fourth Quarter 2019 Results

Net sales increased 25.5% to $72.2 million in the fourth quarter of 2019 from $57.5 million in the fourth quarter of 2018 due to a 43% increase in tons produced, partially offset by a 12% decrease in selling price per ton. The increase in tons produced was due to increased demand. The decrease in selling price per ton was due to a change in product mix.

Gross profit increased 149.4% to $16.9 million (23.4% of net sales) in the fourth quarter of 2019 from $6.8 million (11.8% of net sales) in the fourth quarter of 2018. The increase in gross profit was primarily due to increased production volume, as well as net insurance recoveries. During the fourth quarter of 2019, the Company recorded $1.3 million of business interruption insurance proceeds net of incremental production costs resulting from the fire at the Company’s Saginaw facility.

Net income was $12.0 million, or $1.22 per diluted share, in the fourth quarter of 2019, which included $0.1 million in costs associated with our acquisition of Geneva. Net income in the fourth quarter of 2018 was $0.1 million, or $0.02 per diluted share, which included charges associated with the acquisition of Ameron Water Transmission Group, LLC (“Ameron”) as well as other non-recurring items that totaled $2.4 million, net of taxes. Excluding the one-time, non-recurring items identified in the Company’s Reconciliation of Non-GAAP Financial Measures, adjusted net income per diluted share was $1.23 in the fourth quarter of 2019 compared to $0.27 in the fourth quarter of 2018.

Backlog represents the balance of remaining performance obligations under signed contracts (“Backlog”). Backlog was $199 million as of December 31, 2019 compared to $211 million as of September 30, 2019 and $81 million as of December 31, 2018. The Company also has projects for which it has been notified that it is the successful bidder, but a binding agreement has not been executed (“Confirmed Orders”). Backlog including Confirmed Orders was $258 million as of December 31, 2019 compared to $270 million as of September 30, 2019 and $252 million as of December 31, 2018.

Full Year 2019 Results

Net sales increased 62.3% to $279.3 million in 2019 from $172.1 million in 2018. The increase in net sales was primarily due to an 81% increase in tons produced, partially offset by a 10% decrease in selling price per ton. The increase in tons produced was due to increased demand coupled with the acquired Ameron operations. The decrease in selling price per ton was due to a change in product mix.

Gross profit increased 290.1% to $47.2 million (16.9% of net sales) in 2019 from $12.1 million (7.0% of net sales) in 2018. The increase in gross profit was primarily due to increased production volume coupled with the addition of the Ameron operations. This increase was partially offset by unrecovered incremental production costs of $1.6 million in 2019 resulting from the fire at our Saginaw facility. Any insurance recoveries associated with these costs will be recorded as they are received in future quarters as we work with our insurer to settle the remaining claim.

Net income was $27.9 million, or $2.85 per diluted share, in 2019 which included $2.3 million of other income ($1.7 million net of taxes) related to a favorable legal settlement involving certain pipe produced at the Company’s former Houston, Texas and Bossier City, Louisiana facilities and $0.6 million ($0.5 million net of taxes) of acquisition costs. Net income was $20.3 million, or $2.09 per diluted share in 2018 which included a $20.1 million bargain purchase gain from the acquisition of Ameron as well as items identified in the Company’s Reconciliation of Non-GAAP Financial Measures table. Excluding the one-time, non-recurring items, adjusted net income per diluted share was $2.73 in 2019 compared to adjusted net loss per diluted share of $0.18 in 2018.
