Northwest Pipe Company Announces Second Quarter 2020 Financial Results

VANCOUVER, Washington—August 4, 2020—Northwest Pipe Company (NASDAQ: NWPX), an industry leader of engineered pipeline systems for water infrastructure, today announced its financial results for the second quarter ended June 30, 2020. The Company will broadcast its second quarter 2020 earnings conference call on Wednesday, August 5, 2020 at 7:00 a.m. PDT.

Second Quarter 2020 Results

Net sales increased 1.1% to $70.0 million in the second quarter of 2020 from $69.2 million in the second quarter of 2019 due to a $12.4 million contribution from the Company’s recently acquired Geneva Pipe Company, Inc. (“Geneva”) operations. Legacy revenue decreased from the second quarter of 2019 due to a 31% decrease in tons produced as a result of the shut-down of the Company’s San Luis Río Colorado (“SLRC”) facility and changes in project timing, which were partially offset by a 20% increase in selling price per ton.

Gross profit increased 57.7% to $13.0 million, or 18.5% of net sales, in the second quarter of 2020 from $8.2 million, or 11.9% of net sales, in the second quarter of 2019 primarily due to improved product pricing in the Company’s steel pressure pipe business and the margin contribution from Geneva. This was partially offset by decreased production volume as well as costs associated with the shut-down of the Company’s SLRC facility. Since lifting restrictions previously imposed, the Mexican authorities have allowed for weekly increases to the Company’s workforce beginning in June. Additionally, as a result of the fire at the Company’s Saginaw facility in April 2019, $1.8 million of business interruption insurance recovery was recorded in the second quarter of 2020, compared to $3.2 million of incremental production costs in the second quarter of 2019.

Net income was $6.0 million, or $0.61 per diluted share, in the second quarter of 2020 compared to $3.0 million, or $0.31 per diluted share, in the second quarter of 2019. After considering non-recurring items, adjusted net income was $4.4 million, or $0.45 per diluted share, in the second quarter of 2020, compared to $5.4 million, or $0.55 per diluted share, in the second quarter of 2019. See the Company’s “Reconciliation of Non-GAAP Financial Measures” in the table below.

Backlog represents the balance of remaining performance obligations under signed contracts for water infrastructure steel pipe projects. Backlog was approximately $159 million as of June 30, 2020 compared to $170 million as of March 31, 2020 and $180 million as of June 30, 2019. 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 $246 million as of June 30, 2020 compared to $224 million as of March 31, 2020 and $276 million as of June 30, 2019.

Management Commentary

“Our SLRC Mexico facility was ordered to be shut-down by the Mexican authorities in early April due to COVID-19 and was idle for the majority of the second quarter, which had an overall adverse impact on our revenue and gross profit,” said Scott Montross, President and CEO of Northwest Pipe Company. “As of June 1^st, we received authorization to resume partial operations at SLRC and are working toward normal production levels. We are pleased to now be operating all of our production facilities through the pandemic. Although second quarter revenue in our legacy business was lower year-over-year due to the shut-down of the SLRC facility and changes in job timing, bidding activity has remained strong, which resulted in an improved backlog and strong precast order book. Due to the complex nature of the impact of COVID-19 on the economy, it is difficult to make forward-looking projections on our revenue and margins though we firmly believe the structure of our business remains solid.”

Balance Sheet Details

Total cash and cash equivalents were $19.2 million as of June 30, 2020, up from $9.7 million as of March 31, 2020 primarily due to changes in working capital which more than offset cash outflows for capital expenditures and debt service.

As of June 30, 2020, the Company had $15.4 million of outstanding term loan borrowings and no borrowings under its revolving line of credit with additional borrowing capacity of $55.1 million.
