PRESS RELEASE

**Denison Announces Award of Construction Management Contract to**

**Wood Canada for the Phoenix Uranium Mine**

**Toronto, ON – February 17, 2026. Denison Mines Corp.** ("Denison" or the "Company") (TSX: DML; NYSE American: DNN) is pleased to announce that, following a competitive tender process, it has awarded Wood Canada Limited ("Wood"), a global leader in consulting and engineering, with the construction management contract (the "CM Contract") to oversee the building of the Phoenix in-situ recovery uranium mine ("Phoenix", or the "Project"). This is a key milestone for the Project and represents another crucial step towards the commencement of construction.

David Cates, President & CEO of Denison, commented, ***"In anticipation of receiving our Federal permits to prepare the site and construct the Wheeler River project, we are pleased to announce the award of the construction management contract to our trusted partners at Wood. The selection of Wood for construction management allows us to leverage our long-standing relationship with Wood's Canadian team, which began with co-authoring the 2023 Feasibility Study for Phoenix and continued with the detailed design engineering for the Project over the last two years.***

 ***We are actively organizing our teams, including the onboarding of key construction personnel, to ensure we are ready to proceed with site preparation as soon as possible upon receipt of all required permits. Given Denison's strong balance sheet, and advanced state of project engineering, construction planning, and procurement, we stand ready to make a Final Investment Decision and commence construction shortly after securing Federal approval of the Environmental Assessment and Licence to Prepare the Site for & Construct a Mine and Mill."***

John Day, President of Projects Western Hemisphere at Wood, commented: ***"We value Denison's continued trust in our team and look forward to working together to lead the Wheeler River project through the construction phase. Having supported Phoenix from the feasibility stage through detailed design, we understand the technical and execution requirements of this project.***

 ***Our priority is to enable a safe and seamless transition into execution – maintaining continuity of personnel, applying disciplined project management, and ensuring a predictable path to first production for this landmark project in the Canadian uranium industry. We look forward to continuing to work as an integrated team with Denison, combining our complementary project, construction, and uranium expertise to deliver Phoenix safely and successfully."***

The CM Contract currently contemplates procurement and construction management scopes, whereby Wood will be responsible for (i) construction management of the full processing plant scope, (ii) installation of certain site infrastructure, and (iii) integrated project controls, ongoing procurement support, on-site safety oversight, as well as maintaining reporting and performance management standards (the "Services"). The Services will be provided by Wood in close consultation with Denison, with members of Wood's team and Denison's team holding complementary roles in an integrated project management team.

The selection of Wood for the CM Contract provides important continuity between the engineering and execution phases of the Project and aims to enable the efficient and reliable delivery of the Project during an estimated 24-month construction period. Denison has entered into the CM Contract as the operator of the Project on behalf of the Wheeler River Joint Venture.

 ***About Wheeler River***

 *Wheeler River is the largest undeveloped uranium project in the infrastructure-rich eastern portion of the Athabasca Basin region, in northern Saskatchewan. The project is host to the high-grade Phoenix and Gryphon uranium deposits, discovered by Denison in 2008 and 2014, respectively, and is a joint venture between Denison (90% and operator) and JCU (Canada) Exploration Company Limited ("JCU", 10%). In August 2023, Denison filed a technical report (the "Wheeler River Report") summarizing the results of (i) Phoenix FS; and (ii) a cost update to the 2018 Pre-Feasibility Study for conventional underground mining of the basement-hosted Gryphon uranium deposit. Based on the respective studies, both deposits have the potential to be competitive with the lowest cost uranium mining operations in the world. Permitting efforts for the planned Phoenix ISR operation commenced in 2019 and are nearing completion with approval in July 2025 of the Project's EA by the Province of Saskatchewan and conclusion in December 2025 of the Canadian Nuclear Safety Commission Public Hearing for Federal approval of the EA and project construction license. More information is available in the technical report titled "NI 43-101 Technical Report on the Wheeler River Project Athabasca Basin, Saskatchewan, Canada" dated August 8, 2023 with an effective date of June 23, 2023, and an update to estimated Phoenix initial capital costs disclosed by press release dated January 2, 2026, copies of which are available on Denison's website and under its profile on SEDAR+ at www.sedarplus.ca and on EDGAR at www.sec.gov/edgar.*
