THE WOODLANDS, TX, December 12, 2025 - Perma-Pipe International Holdings, Inc. (NASDAQ: PPIH) announced today financial results for the third quarter and fiscal year-to-date period ended October 31, 2025.

“For the three months ended October 31, 2025, net sales were $61.1 million, an increase of $19.5 million, or 46.9%, compared to $41.6 million in the same quarter of the prior year. Growth was driven by higher sales volumes in both the Middle East and North America. Gross profit was $21.0 million, up $6.9 million from $14.1 million last year, reflecting higher activity levels. Selling, general and administrative expenses increased to $8.3 million from $7.3 million, primarily due to higher payroll and professional fees, including approximately $0.5 million relating to Sarbanes-Oxley 404 compliance in connection with our transition from a small reporting company to an accelerated filer. The Company’s effective tax rate (“ETR”) was 27%, compared to 32% in the prior-year quarter, reflecting the impact of product mix in various tax jurisdictions. As a result, net income attributable to common stock was $6.3 million, an increase of $3.8 million, or 152.0%, compared to $2.5 million in the third quarter of fiscal 2024,” noted President and CEO Saleh Sagr.

“For the nine months ended October 31, 2025, net sales were $155.8 million, an increase of $42.4 million, or 37.4%, compared to $113.4 million in the prior-year period. The increase was primarily attributable to higher sales volumes in both the Middle East and North America. Gross profit was $52.2 million, compared to $38.1 million in the prior year period, reflecting increased activity levels during the current year. General and administrative expenses were $26.1 million, up from $19.5 million, due to higher payroll and professional fees, including approximately $1.0 million relating to Sarbanes-Oxley 404 compliance in connection with our transition from a small reporting company to an accelerated filer. This also includes a one-time compensation charge of approximately $2.0 million related to the departure of the previous CEO. The Company’s effective tax rate was 29%, compared to 28% in the prior-year period. The increase in the Company's tax rate was impacted due to product mix in various tax jurisdictions and as a result of a tax limitation relating to the one-time charge in connection with the previous CEO's departure. Net income attributable to common stock increased to $12.1 million, an increase of $4.9 million, or 68.1%, compared to $7.2 million in the same period of fiscal 2024,” Mr. Sagr commented.

President and CEO Saleh Sagr added: “As of October 31, 2025, our backlog totaled $148.9 million, representing an increase of $10.8 million, or 7.8%, compared with the $138.1 million reported as of January 31, 2025. Our current backlog levels continue to demonstrate substantial growth; in particular, backlog at the end of the third fiscal quarter of 2025 reflects an increase of more than 30% over the backlog recorded at the end of the prior year’s third quarter. This expansion is evident across both North America and the MENA region, underscoring the sustained strength of demand for our solutions.”

“As of October 31, 2025, our year-to-date revenues approximate the revenues reported for the full-year fiscal 2024. Current year-to-date net income attributable to common stock was $12.1 million, an increase of $3.1 million, or 34.4%, compared to approximately $9.0 million in fiscal 2024. The fact that year-to-date net income has exceeded full-year fiscal 2024 results with one quarter remaining in fiscal 2025 reflects continued operational and financial improvement. In addition, net income attributable to common stock for the three and nine months ended October 31, 2025, represents the highest level of earnings since the Company’s transition from MFRI to Perma-Pipe in 2017,” Mr. Sagr continued.

“We have continued to experience solid financial performance, supported by sustained activity in our core markets and improved operating leverage. Our operations in the Middle East and North America delivered strong results, further evidencing the ongoing strengthening of our global platform. This performance is reflected in our quarterly and year-to-date results as well as in the growth of our backlog. These results also align with our strategic initiatives, including our investment in the new Qatar facility, which has secured more than $5.0 million in awards scheduled for execution during the remainder of the year. We remain focused on driving profitable growth and enhancing our competitive position within the markets we serve,” Mr. Sagr concluded.

Third Quarter Fiscal 2025 Results

Net sales were $61.1 million and $41.6 million in the three months ended October 31, 2025 and 2024, respectively.  The increase of $19.5 million was a result of increased sales volumes in the Middle East and in North America.

Gross profit was $21.0 million and $14.1 million in the three months ended October 31, 2025 and 2024, respectively. The increase of $6.9 million was driven primarily by increased volume of activity in the quarter.

General and administrative expenses were $8.3 million and $7.3 million in the three months ended October 31, 2025 and 2024, respectively. The increase of $1.0 million was mainly due to higher payroll expenses and, to a lesser extent, professional fees in the quarter.

Selling expenses were $1.3 million and $1.2 million in the three months ended October 31, 2025 and 2024, respectively. The increase of $0.1 million was due to higher payroll expense in the quarter.

The Company's ETR was 27% and 32% in the three months ended October 31, 2025 and 2024, respectively. The lower ETR for the three months ended October 31, 2025 is due to the mix of income and loss in various jurisdictions.

RECONCILIATION OF NON-GAAP FINANCIAL MEASURE

ADJUSTED INCOME BEFORE TAX

(In thousands)

(Unaudited)

The following information contains a reconciliation of the non-GAAP financial measure of adjusted income before income tax and income before tax prepared in accordance with generally accepted accounting principles ("GAAP") for the three and nine months ended October 31, 2025 and 2024, respectively. This reconciliation is intended to provide investors with useful information in evaluating the Company's performance. Adjusted income before tax includes certain adjustments as identified below. This measure is not considered an alternative to income before tax or other financial measures of performance that are prepared in accordance with GAAP. The Company believes that the exclusion of certain items from income before tax allows investors to more effectively evaluate the Company's operating performance and identify trends that might not be apparent due to the variability and infrequent nature of these items. In addition, the Company believes this measure provides meaningful information to investors when comparing results between periods and performance with respect to the Company's peers. 

Adjustments made for certain items are further described as follows: (i) one-time charge in connection with the acceleration of executive compensation; (ii) other non-recurring charges. As a result of these adjustments, some items that affect income before tax may not be comparable to similar measures of other companies.

The following table provides a reconciliation of the GAAP and non-GAAP financial measure:
