Merger Arbitrage: 18% Spread (at A$0.135/share)
Here’s another merger arb setup with a ~17% spread and closing expected in 3 months.
Cygnus Metals is a junior miner developing a copper/gold project in Canada. The company has agreed to be acquired by copper producer Central Asia Metals for 0.06 CAML shares per Cygnus Metals share. The gross spread currently stands at 18%, and there are plenty of shares available to borrow at a 2.65% fee. The shareholder meeting is set for September, with closing expected shortly after. Four major shareholders, collectively holding 29% of Cygnus, support the transaction. Management holds another 2.5%. The buyer’s shareholder approval will be required as well. Regulatory issues are unlikely. Cygnus is also listed on the TSX Venture Exchange, but liquidity there is much lower.
Cygnus is currently finalizing a preliminary economic assessment for its copper/gold project. After that, a definitive feasibility study would take another 3 years. Meanwhile, Central Asia Metals already has two producing sites: a copper mine in Kazakhstan and a zinc/lead mine in North Macedonia. CAML has a strong balance sheet and generates ~US$50m in FCF annually. Following the merger, the ownership mix in the combined company will be 30% Cygnus and 70% CAML. For Cygnus holders, the all-stock deal allows them to retain meaningful exposure to the Canadian asset while ensuring development funding all the way through to construction. For CAML, it provides an expansion into a top-tier jurisdiction.
CAML has been hunting for a larger acquisition for some time. Last year, it tried to buy Australian New World Resources but was eventually outbid by a PE firm. It is clearly determined not to lose this one. To that end, CAML secured a call option deed with Ocean Partners, Cygnus’ largest shareholder and debtholder with a 12.8% stake. The option lets CAML acquire a 9.9% stake from Ocean Partners at the same exchange ratio if Cygnus receives a competing proposal that the board declares superior. This shows that Ocean Partners finds CAML shares attractive at this ratio and would agree to sell/make an exchange even if CAML doesn’t end up buying Cygnus. Moreover, the two largest holders have agreed not to sell their Cygnus shares until the earlier of the scheme meeting or four months passing from the support agreement.
Cygnus’ shareholder vote will need approval from 75% of votes cast, a majority of shareholders present and voting, and a simple majority of disinterested holders. Ocean Partners will likely be deemed an interested party, given that it was classified as such during Cygnus’ 2024 merger with Dore Copper due to a certain debt-related arrangement. The minority vote should pass regardless: it is extremely rare for minority holders to block a stock-for-stock merger backed by the four largest owners.
The main risk for the vote is CAML’s share price volatility. The buyer’s stock is down 10% since announcement, and any additional decline would erode the deal value further. That looks unlikely, though. CAML already trades at 5x last year’s FCF, with this year’s projected higher, and it sits near the bottom of its 10-year trading range.
The merger must also be approved by CAML shareholders. The deal wasn’t exactly well received, as illustrated by the initial 15% drop in the buyer’s share price. Some shareholders were probably disappointed that, rather than buying back cheap stock, CAML will be plowing cash into developing a new project. Management specifically signaled it would not reinstate the buyback for now, given the additional capex outflows. On the other hand, CAML has always been open about its search for a large acquisition, and had previously noted that a new development project was one of the options. The dividend also stays in place, and CAML gains diversification into a top-tier jurisdiction. The initial shock seems to have subsided already. The stock has stabilized and rebounded 7% off the bottom. CAML has no major holders aside from FIL Investment International (9.8%) and Perpetual Limited (3.9%), neither of which has voiced opposition so far. So there’s a decent chance the majority vote will pass.
Even though copper is designated a critical mineral in Canada, regulatory review should not be an issue. Despite the name, Central Asia Metals is a UK-headquartered company with UK management. Canada’s interventions on critical minerals have so far been aimed primarily at Chinese buyers rather than Western firms. In 2022, for example, Canadian regulators allowed Australia’s Wyloo Metals to acquire Noront Resources, whose critical mineral portfolio included a flagship nickel-copper deposit in Ontario.
Regulatory approvals will also be required in Kazakhstan and North Macedonia, where CAML’s current mines are located. This is somewhat unusual, but apparently stems from the 30% dilution to CAML, which triggers a review by local mining license agencies. The dilution is below a control threshold, and Cygnus has no controlling or especially large shareholders, so getting the consents should be easy.
To sum up, the spread exists because this is a cross-border micro-cap deal, with some uncertainty around CAML’s shareholder vote and some risk from CAML share price volatility. There is borrow risk as well: IB shows 1.7m CAML shares available, but 79m shares will be issued in this transaction, so fees could spike closer to deal finalization. Downside to pre-announcement levels is 10-15% on the long position, and another 10% on the hedge.
So this is buy shares on the Aussie exchange, get paid in shares on the LSX?
You can hedge the buyer’s stock, and the position will auto close once the deal completes and stock is exchanged. Currency exposure can be hedged as well.
Cygnus released its June 2026 quarterly, which mostly reaffirms the merger timetable underpinning the thesis. The Scheme Booklet (including the Independent Expert’s Report) is scheduled for release in August, with the Scheme Meeting still “expected to be held in September 2026” and implementation “to occur shortly thereafter.” CAML will separately convene its own shareholder meeting to approve the allotment of the new CAML shares. So no change to the ~3-month closing horizon. Nothing in the filing addresses CAML’s own shareholder vote or the Kazakhstan/North Macedonia consents, which remain outstanding.

The scheme booklet will be released on August 13 or shortly after. The shareholder meeting remains on track for September, with closing expected in October. The company also provided an update on the regulatory process. Macedonian approval has now been received. The required documents have also been submitted to Kazakh regulators, with the review ongoing under a normal timeline.

Scheme booklet release delayed until August 20. Shareholder meeting has been scheduled for September 18.
The scheme booklet is out, but ASX is still empty for now. Should show up soon.

CAML shareholders will vote on the merger on September 4. If it is approved, the Cygnus shareholder meeting follows two weeks later. CAML recently reported strong H1 results and continues to print cash. The buyer’s stock has recovered +30% from its initial post-merger drop. Risk on the CYG side therefore looks low. The main uncertainty remains CAML’s shareholder approval, which is what keeps the spread at 25%. Most of that spread should disappear if the buyer’s vote passes on Friday.
CAML shareholders approved the merger – I saw this as the main hurdle that could derail the transaction. The spread now stands at 10-12%. Two milestones are still remaining: Kazakhstan regulatory approval and CY5.AX shareholder approval. Both are highly likely to pass.
The rest of the spread is probably driven by low liquidity of CY5 as well as cross-border nature of the transaction, which likely requires some of Australian shareholders to open new brokerage accounts to facilitate the exchange. From the recent press release:

Does anyone know if IBKR can handle the exchange without any additional effort by the user?
I haven’t had any problems with these so far.
Does the 10% math above include the Sep 24 dividend that would be paid on the hedge?
You’re correct. Back in June I originally expected this deal to close in mid-September, so the dividend just slipped my mind. CY5 has gone up since Friday and the spread has been eliminated now.
