History
Alio Gold sold its San Francisco Mine in spring 2020, then merged with Argonaut Gold in a deal completed on July 1, 2020.
2017-2019: Growing the share base
The record seen here says little about Alio Gold's early years. What it does show is the share count: 44,678,701 shares at the end of 2017, 84,707,143 at the end of 2018 and 85,993,371 at the end of 2019. The disclosures provided do not explain what caused the large rise in 2018, so this history does not try to. The company was based in Vancouver, with Mark Backens as President and CEO.
2020: A sale and a merger
The story turned in early 2020. On March 6, Alio announced it was selling its San Francisco Mine. On March 30, it announced a "friendly at-market merger" with Argonaut Gold, meaning a deal without a special premium over the market price. The filings seen are only cover pages pointing to press releases, so the buyer, the price and the exchange ratio are not stated.
The mine sale came first. Alio announced on May 7 that it had completed it. Proxy advisers ISS and Glass Lewis had recommended shareholders vote in favour of the merger, and on May 20 Argonaut shareholders and Alio securityholders approved it.
On July 1, 2020, Argonaut Gold and Alio Gold announced that the merger was complete. At that date, both major threads of the year had been resolved: the mine was sold and the merger was done. The filings do not say what Alio shareholders received, what assets Alio held at the end, or what became of Alio's listing and its status as a company.
