ENGINE CAPITAL ISSUES LETTER TO DYE & DURHAM SHAREHOLDERS REGARDING ITS EFFORTS TO IMPROVE PERFORMANCE AND OVERSIGHT

Engine Capital LP, which owns approximately 6.6 per cent of Dye & Durham Ltd.'s outstanding shares, has issued the following letter to shareholders:

April 25, 2024

Fellow shareholder:

Engine Capital is a meaningful shareholder of Dye & Durham, holding approximately 6.6 per cent of the company's outstanding shares. Over the past few months, we have privately and repeatedly engaged with the board of directors on its current strategy, capital allocation approach and composition. We are now compelled to publicly raise our concerns regarding Dye & Durham's underperformance and strategic missteps after our private attempts to work constructively with the board fizzled out. Our sole focus is to address and rectify the company's most pressing issues:

• Long-term underperformance: Dye & Durham's total shareholder returns have been disappointing over every relevant period, as seen herein.

• All-time low EBITDA multiple: The company's EBITDA (earnings before interest, taxes, depreciation and amortization) multiple is nearing an all-time low and lingers at a significant discount to peers, reflecting investors' significant concerns about the board's misguided decisions.
• Poor capital allocation:
  • Paying elevated multiples for acquisitions: The board has paid an aggregate multiple around 16 times EBITDA versus the company's current multiple of around 7.5 times 2025 EBITDA. Even when synergies and pricing increases are taken into account, the multiples paid for acquisitions are still well above Dye & Durham's current multiple;
  • Dilutive share issuance: The board authorized repurchasing 14.7 million shares for an average price of $15.22 per share in fiscal year 2023 (including through two substantial issuer bids). It then turned around just a few months later and completed a highly dilutive equity issuance of 11.96 million shares at $12.10 per share in February, 2024;
  • Mismanaging refinancing the company's $345-million convertible: Despite the company's best efforts, this debenture is still outstanding and is now trading close to par;
  • Incurring unnecessary costs: A combined $134-million in acquisition, restructuring and other costs was incurred in fiscal 2021, 2022 and 2023 -- representing almost 15 per cent of the company's market capitalization. This is an exorbitant number that reflects the frenetic pace of capital market activity under the current board.
• Misaligned incentives:
  • Establishing the wrong long-term operational target for the company: A framework targeting $1-billion EBITDA incentivizes acquisitions -- even if they do not create shareholder value. There should be no pressure on management or the board to reach an arbitrary EBITDA target.

To maximize the value of Dye & Durham, the board needs to incentivize management to optimize its return on invested capital, focus on organic growth, and consider acquisitions in a measured and disciplined way -- instead of trying to hit an arbitrary EBITDA target.

While we still hope to reach a constructive resolution with the board, we are increasingly concerned the board may resort to scorched-earth tactics, including pursuing frivolous legal actions against Engine and other shareholders. We believe the board is aware that many independent shareholders are aligned with our view that change is essential but is nonetheless focused on protecting incumbents' board seats by all means necessary, including by spending a significant amount of shareholders' money on hiring multiple law firms and defence advisers.

The board should proceed with caution, as it would be a grave mistake if the company took steps to disenfranchise its shareholders. Boards that pursue frivolous legal actions against their own shareholders do so at their own peril.

Such actions would only further underscore how the current directors are unfit to oversee Dye & Durham on behalf of shareholders.

Sincerely,

Arnaud Ajdler

Managing partner
