Perma-Pipe International Holdings, Inc. Announces its Second Quarter and Year-to-Date Fiscal 2021 Financial Results

•        The Company generated net sales of $39.8 million for the second quarter

•        Net income was $3.4 million in the second quarter compared to $0.3 million in the same quarter of 2020

•        Backlog stood at $53.2 million on July 31, 2021 compared to $52.6 million on January 31, 2021

NILES, IL, September 8, 2021 - Perma-Pipe International Holdings, Inc. (NASDAQ: PPIH) announced today financial results for the second quarter ended July 31, 2021.

“Second quarter revenues of $39.8 million represent a significant increase above the revenues of $20.4 million achieved in the same quarter last year. Similarly, pre-tax income from operations of $4.3 million is significantly greater than the $0.2 million earned in the same quarter of 2020.  If we exclude the impact of COVID-19 related government assistance, pre-tax income from operations improved $7.5 million over the same quarter of 2020 and $9.2 million for the year-to-date versus the same period last year," noted President and CEO David Mansfield.

"As I stated in our last Earnings Release, the adverse business conditions arising as a result of the pandemic began to ease during the latter part of the first quarter. This continued through the second quarter, and we were able to begin the execution of some delayed projects. Further confirming the commencement of a recovery from the previously depressed conditions, almost all business units showed quarter over quarter growth. Overall, revenues increased 63%, or $15.4 million, over those achieved in the first quarter, and pre-tax income increased by almost $5 million.

"Steps taken earlier this year to enhance liquidity included the sale and lease back of our property in Lebanon, Tennessee. This provided capital to allow us to continue to move forward with investment plans that we had delayed as an act of prudence over any risk to working capital available to us in the future. With the recent recovery in our earnings, we are now in a much more secure position in this regard and we will continue to move forward with our growth plans.

"Our backlog currently stands at $53.2 million, which reflects a small increase from the backlog at January 31, 2021. In addition to the growth in revenue during the quarter and year-to-date, new awards have also continued at higher levels, allowing us to maintain our backlog at a similar level to that at the beginning of the year.

"While we continue to be faced with dealing with the adverse impact of the pandemic, including the challenges it has presented within the supply chains, it is nevertheless encouraging to have more confidence that we are emerging from the worst of its impact on our business,” Mr. Mansfield concluded.

Second Quarter Fiscal 2021 Results 

Net sales were $39.8 million in the current quarter, an increase of $19.4 million, or 95%, from $20.4 million in the prior year quarter. The increase was a result of increased sales volumes in both North America and the Middle East due to recovery from the effects of the COVID-19 pandemic. In addition, the Company's U.A.E. business benefitted from the introduction of a new product line. 

Gross profit increased to $10.7 million, or 27% of net sales, in the current quarter from $2.4 million, or 12% of net sales, in the prior year quarter. This increase was driven by higher sales volumes and project mix.

General and administrative expenses increased $1.1 million, or 25%, from the prior year quarter. This increase was driven by personnel related expense increases corresponding to the business activity increases during the period. 

Selling expenses decreased to $1.1 million in the current quarter, compared to $1.3 million in the prior year quarter due primarily to organizational changes in the roles of certain corporate employees. 

Net interest expense increased to $0.3 million in the current quarter from $0.1 million in the prior year quarter. This increase was primarily related to the sale leaseback transaction for our operating facility in Tennessee entered into in April 2021. 

Other income, net decreased to an income of $0.5 million in the current quarter, compared to income of $3.7 million in the prior year quarter. This decrease was a result of income recorded in the prior year quarter for funds received under the PPP program of $3.2 million.

Income from operations before income taxes increased by $4.1 million to $4.3 million in the current quarter from $0.2 million in the prior year quarter. The increase was a result of increased sales volumes in both North America and the Middle East due to recovery from the effects of the COVID-19 pandemic. In addition, the Company's U.A.E. business benefitted from the introduction of a new product line. 

The Company's worldwide effective tax rates ("ETR") were 20.1% and (56.8%) in the current quarter and the prior year quarter, respectively. The change in the ETR from the prior year quarter to the current year quarter is largely due to changes in the mix of income and loss in various jurisdictions.

The resulting net income of $3.4 million in the current quarter was an improvement of $3.1 million over the $0.3 million in the prior year quarter. The increase was a result of increased sales volumes in both North America and the Middle East due to recovery from the effects of the COVID-19 pandemic. In addition, the Company's U.A.E. business benefitted from the introduction of a new product line.

General and administrative expenses were $10.0 million in the current year-to-date, an increase of $1.2 million, or 14%, from $8.8 million in the prior year year-to-date.

Selling expenses decreased to $2.1 million in the current year-to-date, compared to $3.0 million in the prior year year-to-date due to organizational changes in the roles of certain corporate employees as well as the continued effects of cost reduction strategies implemented during the COVID-19 pandemic. 

Net interest expense remained relatively consistent, increasing slightly from $0.3 million in the prior year year-to-date to $0.4 million in the current year-to-date.
