RARE DEADLINE ALERT: ROSEN, SKILLED INVESTOR COUNSEL, Encourages Ultragenyx Pharmaceutical Inc. Investors with Losses in Excess of $100K to Secure Counsel Before Important Deadline in Securities Class Action – RARE

NEW YORK, March 18, 2026 (GLOBE NEWSWIRE) —

WHY: Rosen Law Firm, a global investor rights law firm, reminds purchasers of common stock of Ultragenyx Pharmaceutical Inc. (NASDAQ: RARE) between August 3, 2023 and December 26, 2025, inclusive (the “Class Period”), of the important April 6, 2026 lead plaintiff deadline.

SO WHAT: If you purchased Ultragenyx common stock during the Class Period you may be entitled to compensation without payment of any out of pocket fees or costs through a contingency fee arrangement.

WHAT TO DO NEXT: To join the Ultragenyx class action, go to https://rosenlegal.com/submit-form/?case_id=52472 or call Phillip Kim, Esq. toll-free at 866-767-3653 or email [email protected] for information on the class action. A class action lawsuit has already been filed. If you wish to serve as lead plaintiff, you must move the Court no later than April 6, 2026. A lead plaintiff is a representative party acting on behalf of other class members in directing the litigation.

WHY ROSEN LAW: We encourage investors to select qualified counsel with a track record of success in leadership roles. Often, firms issuing notices do not have comparable experience, resources, or any meaningful peer recognition. Many of these firms do not actually litigate securities class actions, but are merely middlemen that refer clients or partner with law firms that actually litigate the cases. Be wise in selecting counsel. The Rosen Law Firm represents investors throughout the globe, concentrating its practice in securities class actions and shareholder derivative litigation. Rosen Law Firm has achieved, at that time, the largest ever securities class action settlement against a Chinese Company. Rosen Law Firm was Ranked No. 1 by ISS Securities Class Action Services for number of securities class action settlements in 2017. The firm has been ranked in the top 4 each year since 2013 and has recovered hundreds of millions of dollars for investors. In 2019 alone the firm secured over $438 million for investors. In 2020, founding partner Laurence Rosen was named by law360 as a Titan of Plaintiffs’ Bar. Many of the firm’s attorneys have been recognized by Lawdragon and Super Lawyers.

DETAILS OF THE CASE: According to the lawsuit, defendants provided investors with material information concerning Ultragenyx’s expected results for its Phase III Orbit and Cosmic Studies, which tested setrusumab (UX 143) in patients with Osteogenesis Imperfecta (“OI”). Defendants’ statements included, among other things, confidence in setrusumab’s ability to ultimately trigger a decrease in the OI patients’ annualized fracture rate, alongside confidence in the study designs to demonstrate such ability and reduce testing variability that could interfere with such a result.

The lawsuit claims that defendants provided these overwhelmingly positive statements to investors while simultaneously disseminating materially false and misleading statements and/or concealing material adverse facts concerning the true state of setrusumab’s potential, as well as the true risk inherent in the study protocols put forth; notably, that while setrusumab does increase material bone density, this increase does not correlate to a decrease in annualized fracture rates or otherwise, that the Phase III Orbit and Cosmic studies were much less likely to be able to demonstrate such a link than management claimed. The lawsuit claims that such statements absent these material facts caused Ultragenyx shareholders to purchase Ultragenyx securities at artificially inflated prices. When the true details entered the market, the lawsuit claims that investors suffered damages.

No Class Has Been Certified. Until a class is certified, you are not represented by counsel unless you retain one. You may select counsel of your choice. You may also remain an absent class member and do nothing at this point. An investor’s ability to share in any potential future recovery is not dependent upon serving as lead plaintiff.

Namib Minerals Names New CEO

NEW YORK, March 18, 2026 (GLOBE NEWSWIRE) — Namib Minerals (“Namib” or the “Company”) (Nasdaq: NAMM) today announced a leadership transition as part of its strategic growth plan. The Company’s Board of Directors has appointed Tulani Sikwila as Chief Executive Officer, effective 18 March 2026, succeeding Ibrahima Sory Tall who is leaving Namib to pursue other opportunities. Mr. Sikwila previously served as Namib’s Chief Financial Officer. The Company has initiated a search for an Interim CFO to ensure continuity in financial leadership during this transition.

Leadership Transition

Mr. Sikwila brings more than 20 years of experience in financial operations and leadership. Having been with Namib Minerals, Greenstone, and its predecessor companies for close to two decades, he possesses an unparalleled understanding of the Company’s history, assets, and strategic priorities. His deep institutional knowledge, regional networks, and proven track record have been integral to Namib’s success to date and will be invaluable as he leads the Company into its next phase of growth. Mr. Sikwila is a Chartered Accountant of England and Wales and holds an Executive Master of Science in Finance from HEC Paris. He previously worked as a financial auditor at Ernst & Young in Zimbabwe.

Molly P. Zhang, Chair of the Board, commented on the leadership transition: “On behalf of the Board, I would like to thank Mr. Tall for his leadership and dedication to Namib Minerals during a pivotal period in the Company’s history, including guiding the organization to the important milestone of becoming the first Black African-founded and -led mining company to be listed on a New York stock exchange in mid-2025. We congratulate Mr. Sikwila on assuming the role of Chief Executive Officer at a critical time for the Company. With more than two decades of leadership experience spanning operations and finance, together with his deep understanding of the business and the region, Tulani is well positioned to lead Namib through its next phase of transformation. His financial expertise and strong knowledge of the Company will be instrumental as we accelerate our growth strategy and advance Namib’s trajectory toward becoming an African investment platform focused on strategic resource opportunities through capital efficiency and scalable organic growth.”

“I look forward to guiding our growing team at this pivotal moment for the Company,” commented incoming CEO Tulani Sikwila. “I am deeply appreciative of the Board’s confidence and of Ibrahima’s leadership over the past years. As we expand operations Namib Minerals is well-positioned to responsibly unlock Africa’s resource potential while delivering lasting value to our investors, communities and other stakeholders.”

Expanding the Senior Leadership Team

In addition, Namib Minerals is pleased to welcome Antonio Nieto as Vice President, Technical Services. His appointment marks a significant step in strengthening the Company’s operational and technical capabilities, as it advances its flagship How Mine – a proven asset that produced 33,600 ounces of gold in 2024 – along with two additional brownfield growth projects in Zimbabwe. A search process for a Chief Operating Officer is currently underway.

With more than 25 years of global mining leadership, Antonio Nieto is an internationally recognized expert in mining technology, innovation, and sustainability. He has held senior roles at FLSmidth, Gold Fields, Industrias Peñoles, and Mining3, and he authored The 5S Innovation Model for the Minerals Industry. Mr. Nieto has served as Adjunct Professor of Mining Engineering at the University of Utah and held several prestigious academic appointments, including as Chair of the Minerals Resources and Reserves program at the University of the Witwatersrand, mentoring the next generation of mining engineers and integrating cutting-edge technologies, such as AI and blockchain, into the mining value chain. He holds a Ph.D. in Earth Systems and Mining Engineering and a Master of Science in Mining and Minerals Engineering from the Colorado School of Mines, a Master of Science in Geostatistics from Mines Paris – PSL, and a Bachelor of Science in Mining and Metallurgy Engineering from Universidad de Guanajuato.

“These leadership changes position Namib Minerals for its next phase of growth,” Molly Zhang added. “Namib’s next chapter is about transforming from a single-asset producer into broader platform to capitalize on strategic resource opportunities, and this leadership configuration is purpose-built for that transformation.”
