Lion Copper Corp. has completed the restructuring of its secured convertible debentures, as previously announced in the company's news release dated Oct. 12, 2026, and has engaged Atrium Research Corp. to provide equity research services to the company.

Completion of debenture restructuring

The company has completed the restructuring of its previously issued secured convertible debentures in the aggregate principal amount of $2.7-million, bearing interest at a rate of 12 per cent per annum and originally maturing on Nov. 6, 2026. The debentures were originally issued on Nov. 6, 2025.

The key terms of the restructured debentures are as follows:

Extended maturity:  The maturity date of the debentures has been extended from Nov. 6, 2026, to May 6, 2027.

Accrued interest:  All interest accrued on the debentures will be paid as at Nov. 6, 2026.

Interest during the extended term:  Interest on the restructured debentures will remain payable in cash or common shares of the company, as determined by the company, as at the extended maturity date.

Conversion price:  The debentures remain convertible into common shares of the company at a conversion price of $2.6055 (U.S.) per share.

In connection with the debenture restructuring, the company has issued an aggregate of 518,135 common share purchase warrants to the holders of the debentures. Each warrant entitles the holder thereof to purchase one common share of the company at an exercise price of $4.17 (U.S.) per share until Nov. 6, 2031.

The warrants and any shares issuable upon exercise of the warrants are subject to a statutory hold period of four months from the date of issuance, expiring on Feb. 21, 2027, in accordance with applicable Canadian securities legislation.

Engagement of Atrium Research Corp.

The company has engaged Atrium Research, a Toronto-based equity research firm, to provide research services to assist the company in presenting its investment case to potential investors, including fund managers, family offices and high-net-worth individuals.

Under the engagement, Atrium Research will publish an in-depth initiation report on the company, including an investment thesis, analysis of the company's strategy and outlook, peer comparison, financial analysis with estimates, and a valuation and target price. The initiation report is expected within three to five weeks of the initial payment. Atrium Research will also publish at least four additional research reports during the term of the engagement, tied to the company's material news, and will conduct two video interviews with management. Atrium Research's reports and financial estimates are distributed through platforms including Bloomberg, Refinitiv, FactSet, S&P Global and AlphaSense, as well as to its email distribution focused on the small and micro-cap market.

In consideration of the services to be provided, the company will pay Atrium Research an upfront cash fee of $38,000 (plus applicable GST) for an initial term commencing Oct. 15, 2026, and ending June 30, 2027. Following the initial term, the engagement will continue on a quarter-to-quarter basis at a fee of $12,000 (plus applicable GST) per quarter, unless the company elects otherwise in writing at least 30 days before the end of the initial term. Either party may terminate a quarter-to-quarter extension on 30-day written notice. The company will also reimburse Atrium Research for reasonable out-of-pocket expenses approved in advance by the company. No securities of the company will be issued to Atrium Research as compensation for its services.

Atrium Research retains editorial direction over the content of its research reports and financial models, which are based on publicly available information, industry data and discussions with management. Atrium Research will provide content to the company for fact-checking and will make any necessary factual corrections. Atrium Research does not have any interest, directly or indirectly, in the company or its securities, or any right or intent to acquire such an interest.
