Ur-Energy Inc. registered common shares having a maximum aggregate sales price of $50,000,000 for sale through an at-the-market program with B. Riley Securities and Cantor Fitzgerald as agents under an Amended Sales Agreement.
The prospectus supplement describes the ATM mechanics: sales may occur from time to time at market prices, agents receive up to 3.0% commission, proceeds will be used for Lost Creek optimization, Shirley Basin construction and exploration, and the offering supplements a $300 million shelf registration. The Amended Sales Agreement and related amendments are filed and incorporated by reference.
Ur-Energy Inc. filed a shelf prospectus registering up to $300,000,000 of securities, including common shares, warrants, units, rights and senior or subordinated debt, to be offered from time to time in one or more offerings. The prospectus emphasizes risk factors for uranium producers, including market volatility, permitting, operational restart and construction risks at Lost Creek and Shirley Basin, financing and indebtedness (including the $120 million 4.75% Convertible Notes due 2031), and regulatory and environmental uncertainties. The offering proceeds are designated for general corporate purposes and working capital and specific terms will be provided in prospectus supplements.
Ur‑Energy Inc. (URG) filed a prospectus supplement registering up to 19,137,000 common shares issuable upon exercise of outstanding warrants. These shares become issuable only if holders exercise their warrants.
The warrants carry a $1.50 per‑share exercise price. If all registered warrants are exercised for cash, the company would receive approximately $28,705,500 in gross proceeds. Ur‑Energy plans to use any net proceeds to supplement working capital for the continued ramp-up at Lost Creek, support construction and development at Shirley Basin, fund exploration, and for general corporate purposes. Management will have broad discretion in applying proceeds.
The company reports 395,350,376 common shares would be outstanding immediately after this offering (assuming full exercise). In the dilution illustration, net tangible book value per share as of June 30, 2025 would increase from $0.28 to $0.34, implying $1.16 per-share dilution to new investors upon exercise.
