German submarine deal 'unfortunate' for Algoma Steel, Sault Ste. Marie, Ont., region defence expert says
CBC reports Canada is expected to award a multibillion-dollar contract to German shipbuilder ThyssenKrupp Marine Systems (TKMS) to build 12 submarines, replacing the Victoria-class. The South Korean bidder Hanwha Ocean’s MoUs included $345M for Algoma Steel’s Sault Ste. Marie beam mill and Canadian steel use in armoured vehicles; Algoma says it won’t comment until the announcement.
How this was made

The 30-second read
Why it matters
If the Hanwha bid’s industrial tie-ins do not advance, Algoma Steel may face weaker incremental demand expectations and reduced probability of rehiring tied to the mill by end-2026; however, the company is not commenting until the official announcement.
Market read
Procurement outcome likely changes the probability of near-term industrial investment and jobs tied to Algoma Steel’s proposed mill, creating a sentiment catalyst for the stock.
What to watch
The article doesn’t confirm whether the $345M memorandum is terminated; traders may need follow-up on whether Algoma’s mill financing/timelines change after the TKMS award.
Background
Ottawa is selecting a shipbuilder to replace the Royal Canadian Navy’s aging Victoria-Class submarines; Hanwha’s bid included memoranda tied to Algoma Steel’s planned structural steel beam mill and Canadian steel usage in armored vehicle manufacturing.
Ticker impact
Algoma Steel’s $345M Hanwha-linked beam mill plan is described as unsuccessful after Ottawa selects TKMS for Canada’s submarine fleet.
Near-term sentiment likely negative for ASTL on the news that the Hanwha/Algoma component of the bid is not moving forward; magnitude uncertain without explicit financial guidance.
The text frames the Hanwha memoranda as expected economic relief and notes the bid appears unsuccessful, but it does not quantify Algoma’s direct revenue impact or confirm cancellation of the memoranda beyond the procurement outcome.
Market effects
Defense procurement politics may shift near-term demand expectations for Canadian industrial steel supply chains tied to armored vehicle manufacturing.
Sault Ste. Marie/Algoma region loses a stated pathway to rehiring up to 500 laid-off employees by end-2026 tied to the mill hopes.
Reinforces NATO-aligned European sourcing over South Korean bids, with potential knock-on effects for defense-adjacent industrial partners.
Counterpoint
The Hanwha memoranda could still proceed independently of the submarine prime contractor selection, so the steel impact may be delayed rather than eliminated.
