## Exhibit 99.1

**EXHIBIT 99.1**

**Osisko Development Completes US$143.8 Million "Bought Deal" Public Offering of Common Shares Including Full Exercise of Over-Allotment Option**

MONTREAL, Feb. 03, 2026 (GLOBE NEWSWIRE) -- **Osisko Development Corp.** (NYSE: ODV, TSXV: ODV) ("**Osisko Development**" or the "**Company**") is pleased to announce that it has completed its previously announced prospectus offering (the "**Offering**") of common shares of the Company (the "**Common Shares**"). The Offering was completed on a "bought deal" basis, pursuant to an underwriting agreement dated January 27, 2026, among the Company and a syndicate of underwriters comprising National Bank Capital Markets, RBC Capital Markets and Cantor, as co-lead underwriters and co-bookrunners, and BMO Capital Markets (collectively, the "**Underwriters**"). Pursuant to the Offering, the Company issued an aggregate of 40,607,650 Common Shares at a price of US$3.54 per Common Share for aggregate gross proceeds of US$143,751,081, including the exercise in full by the Underwriters of their over-allotment option.

*"We see 2026 as a key inflection point for Osisko Development and our flagship, fully permitted Cariboo Gold Project. Proceeds from this offering unlock our ability to accelerate infill conversion drilling aimed at upgrading existing mineral resources to mineral reserves, potentially setting the stage for a more meaningful annual gold production profile, subject to evaluation of throughput expansion scenarios. Importantly, this work can advance in parallel with, and independent of, our ongoing pre-construction activities and onwards as we progress towards a final investment decision on the base case outlined in the 2025 feasibility study. This is a unique opportunity to potentially enhance project value by converting additional reserve ounces into the mine plan located near or within planned infrastructure, potentially delivering near-term benefits for shareholders,"* **stated Sean Roosen, Chairman and CEO.**

The Company intends to use the net proceeds of the Offering to fund infill conversion drilling and at depth exploration at the Cariboo Gold Project and for general working capital purposes, as further described in the Canadian Prospectus Supplement and the U.S. Prospectus Supplement (each as defined below).

In connection with the Offering, the Underwriters were paid a cash commission equal to 4.5% of the aggregate gross proceeds of the Offering.

The Offering was completed in Canada by way of a prospectus supplement dated January 27, 2026 (the "**Canadian Prospectus Supplement**") to the short form base shelf prospectus of the Company dated December 23, 2025 (the "**Base Shelf Prospectus**"), in each of the provinces and territories of Canada, and was completed in the United States by way of a prospectus supplement (the "**U.S. Prospectus Supplement**") to the base shelf prospectus contained in the Company's effective registration statement on Form F-10 (File No. 333-292328) (the "**Registration Statement**"), which U.S. Prospectus Supplement was filed by the Company with the U.S. Securities and Exchange Commission (the "**SEC**"). Copies of the Base Shelf Prospectus, the Canadian Prospectus Supplement and the documents incorporated by reference therein are accessible under the Company's profile on SEDAR+ at www.sedarplus.ca. Copies of the Registration Statement (including the Base Shelf Prospectus and the U.S. Prospectus Supplement) are accessible on the Company's profile on EDGAR on the SEC website at www.sec.gov.

**<u>Insider Participation</u>**

Double Zero Capital LP ("**Double Zero**"), which is an "insider" of the Company, purchased an aggregate of 8,080,000 Common Shares at a price of US$3.54 for gross proceeds of US$28,603,200 (the "**Double Zero Purchase**") pursuant to the exercise of its pre-emptive rights in respect of the Offering under the investor rights agreement dated August 15, 2025 between Double Zero and the Company. The Double Zero Purchase is considered to be a "related party transaction" for the purposes of Multilateral Instrument 61-101 – *Protection of Minority Security Holders in Special Transactions* ("**MI 61-101**"). The Company did not file a material change report more than 21 days before the expected closing date of the Offering as the details of the Offering and the Double Zero Purchase was not settled until shortly prior to the closing of the Offering, and the Company wished to close the Offering on an expedited basis for sound business reasons. The Company is relying on exemptions from the formal valuation and minority shareholder approval requirements available under MI 61-101. The Company is exempt from the formal valuation requirement in section 5.4 of MI 61-101 in reliance on section 5.5(a) of MI 61-101 as the fair market value of the transaction, insofar as it involves interested parties, is not more than 25% of the Company's market capitalization. Additionally, the Company is exempt from minority shareholder approval requirement in section 5.6 of MI 61-101 in reliance on section 5.7(1)(a) of MI 61-101 as the fair market value of the transaction, insofar as it involves interested parties, is not more than 25% of the Company's market capitalization.

The Offering is subject to the final approval of the TSX Venture Exchange.

*This news release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of the Common Shares in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of that jurisdiction.*
