("Mountain Province", the "Company") (TSX: MPVD) (OTC: MPVD) today announces financial results for the first quarter ended March 31, 2026 ("the Quarter" or "Q1 2026") from the Gahcho Kué Diamond Mine ("GK Mine"). All figures are expressed in Canadian dollars unless otherwise noted. Financial Highlights for Q1 2026 858,000 carats sold, with total proceeds of $40.0 million (US$29.2 million) at an average realised value of $47 per carat (US$34).

Adjusted EBITDA 1 of ($0.6) million. Loss from mine operations of $36.2 million. Net loss of $65.1 million or $0.31 basic and diluted loss per share.

Operational Highlights for Q1 2026 ( all figures reported on a 100% basis unless otherwise stated ) 759,248 ore tonnes treated, a 18% decrease relative to Q1 2025, (Q1 2025: 925,773 tonnes treated;) 2,006,135 carats recovered, 163% higher than Q1 2025 (Q1 2025: 762,978 carats) Average grade of 2.64 carats per tonne, a 222% increase relative to Q1 2025 (Q1 2025: 0.82 carats per tonne) Cost per carat recovered, including capitalized stripping of $53/carat, and cost per tonne processed, including capitalized stripping of $139/tonne. Sales Highlights for Q1 2026 As previously released, during Q1 2026, 858,000 carats were sold for total proceeds of $40.0 million (US$29.2 million), resulting in an average value of $47 per carat (US$34 per carat). These results compare to Q1 2025 when 426,000 carats were sold for total proceeds of $44.0 million (US$30.7 million), resulting in an average price of $103 per carat (US$72 per carat).

Jonathan Comerford, the Company's President, and Chief Executive Officer, commented: The first quarter is historically a challenging period for operations due to adverse weather conditions, Q1 2026 was a particularly cold winter at the GK Mine. During the quarter, total tonnes mined declined significantly compared with Q1 2025, primarily due to the joint venture partners' decision to pause Tuzo waste stripping. Despite these constraints, Q1 2026 was a record quarter for the operation, with more than 2.0 million carats recovered for the first time, representing a 163% increase compared to Q1 2025.

This performance was driven by a significantly higher recovered grade of 2.64 carats per tonne, well ahead of expectations and up 222% year-on-year. While operational performance was exceptionally strong, the benefits of higher production were substantially offset by pricing pressure. During the quarter, 858,000 carats were sold for total proceeds of $40.0 million, at an average realised price of $47 per carat, compared to $103 per carat in Q1 2025.

This reduction was primarily driven by continued weakness in the market and the diamond size mix, with a higher proportion of smaller stones recovered, which remain under the greatest pressure in the current market environment. These pricing conditions, and the uncertainty in the market, prompted the joint venture partner's decision to pause Tuzo waste stripping in order to conserve cash, preserve liquidity, and maintain strategic optionality. On the cost side, cost per carat recovered was $53 and cost per tonne processed was $139, both inclusive of capitalised stripping.

These metrics reflect the lower tonnes treated but the record high level of carats recovered and the largely fixed cost nature of the operation during the winter mining period. As noted in our year-end results commentary, the diamond market continues to be adversely affected by geopolitical uncertainty, including concerns surrounding US tariffs and the ongoing conflict in the Middle East. These factors continue to weigh on demand and pricing—particularly in smaller size categories—and are currently overshadowing what has otherwise been a very strong operational performance at the mine.

Given the sustained weakness in diamond pricing and its impact on cash flow, the Company is operating in a highly constrained and challenging financial environment which, if prolonged, could have implications for the longer-term sustainability of the Company. In response, we are actively and constructively engaging with all key stakeholders, including our joint venture partner, lenders, and relevant government authorities, to preserve liquidity and identify a path forward. We greatly appreciate the continued engagement and support of these stakeholders during what remains a particularly challenging period for the diamond market.

We expect to provide a further update on the outcome of these discussions in the coming weeks.

Reconciliation of Non-IFRS measures This news release refers to the terms "Cash costs of production per tonne of ore processed" and "Cash costs of production per carat recovered", both including and net of capitalized stripping costs and "Adjusted Earnings Before Interest, Taxes Depreciation and Amortization (Adjusted EBITDA)" and "Adjusted EBITDA Margin". Each of these is a non-IFRS performance measure and is referenced in order to provide investors with information about the measures used by management to monitor performance.

These measures are intended to provide additional information and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS. They do not have any standardized meaning under IFRS and therefore may not be comparable to similar measures presented by other issuers. Cash costs of production per tonne of ore processed and cash costs of production per carat recovered are used by management to analyze the actual cash costs associated with processing the ore, and for each recovered carat.

Differences from production costs reported within cost of sales are attributed to the amount of production cost included in ore stockpile and rough diamond inventories. Adjusted EBITDA is used by management to analyze the operational cash flows of the Company, as compared to the net income for accounting purposes. It is also a measure which is defined in the Notes documents.

Adjusted EBITDA margin is used by management to analyze the operational margin % on cash flows of the Company. The following table provides a reconciliation of the Adjusted EBITDA and Adjusted EBITDA margin with the net income on the condensed consolidated interim statements of comprehensive (loss) income: The following table provides a reconciliation of the cash costs of production per tonne of ore processed and per carat recovered and the production costs reported within cost of sales on the condensed consolidated interim statements of comprehensive (loss) income: About Mountain Province Diamonds Inc.
