Form Shareholder Proposal and Supporting Statement

Proposal

RESOLVED: The shareholders of Perma-Pipe International Holdings, Inc. recommend that the Board of Directors authorize and implement a share purchase program as a method of returning capital to shareholders.

Supporting Statement

PPIH's stock price has significantly underperformed all major stock indices during the past five years. There has been only a de minimis return, if any, to shareowners at large during this period. Additionally, PPIH has done very little to enhance shareholder value via returning capital to shareholders either through a share buyback or dividend. In February 2015, PPIH's board of Directors did approve and authorize a $2 million share repurchase program over a two-year period. However, after repurchasing 28,000 shares in February, 2015 and 17,000 shares in March, 2015 at a total cost of $292,510, no additional shares have been repurchased since then. Thus, only 14.63% of the total share repurchase authorization has been implemented.

Notwithstanding this significant lack of performance by PPIH's stock and any significant attempt to enhance shareholder value, large amounts of compensation in the form of cash, stock and stock option awards were imparted to PPIH Senior Executives and members of the Board of Directors during this same five year period. PPIH's publicly filed proxy statements for the years 2012, 2013, 2014 and 2015 disclose that $11,126,827 in such compensation was awarded during these four years.

Presumably, a similar amount was disbursed to PPIH Senior Executives and the Board during 2016. The market capitalization of PPIH as of the filing of this proxy proposal is $64.85 million as of January 17, 2017. Therefore, at least $12,500,000 was disbursed as total compensation to Senior Executives and members of the Board of Directors during 2012-2016 and comprises approximately 20% of the current market capitalization of PPIH. This compensation is excessive when the shareowners at large have received virtually no return on their investment and one unfulfilled attempt by the Board to enhance shareholder value.

PPIH has minimal net debt and has in excess of $9 million in cash in foreign subsidiaries. PPIH's overall balance sheet clearly would support a share buyback program. In addition, by reducing the total number of outstanding shares it would help to facilitate the eventual sale of the Company should the Company decide to pursue that course of action.

We respectfully urge all shareowners to vote in favor of this proposal.
