A few scattered observations about the materials:
“The planned share issue size is tentatively 12 million euros.” & “Anchor investors’ subscription commitments are conditional on them being allocated shares totaling approximately 11.8 million euros.”
→ This means the issue will be oversubscribed (because of the personnel issue + public issue on top of that). But:
“In addition, certain current shareholders of the Company plan to offer existing shares of the Company for purchase if the share issue is oversubscribed, in which case the Company’s Board of Directors has the right to increase the number of shares offered”
I didn’t notice anywhere how large a share this sale would be (vs the issue).
“Anchor investors have committed to subscribing for shares under certain customary conditions and provided that the valuation of the Company’s entire share capital before the share issue is at most 31 million euros”
If we assume a pre-money valuation of that maximum of €31M, then (my calculation corrected 2021-05-21 9:00)
- With 2020 figures: P/E: negative and P/S: 4.8.
- With 2019 figures: P/E: 212 (31,000 / 146) and P/S: 3
If we assume the issue size is €12M, and the 2021 figures materialize according to guidance (revenue €13-15M), then P/S would be 2.8 - 3.3
It is indeed an ambitious goal, if we forget the corona year and look at, for example, 2018->2019 growth, it was 10%. However, that is quite a while ago, so it may not be a relevant comparison in the current situation. If the company hits its guided revenue range for this year (EUR 13-15M), then growth from 2019 would be 30-50%.
The order book at the end of 2020 was quite good (> 10M):

Hallitus - Merus Power Oyj
The board, by the way, is exceptionally small, three members, one of whom is conditional on the listing going through: Hallitus - Merus Power Oyj. Of the members, Riihimäki is from Wärtsilä and Sadeharju is through a private equity investor (board memberships in energy companies).
The question arises for me: has this been rushed to the stock exchange now? The board has not had time to be shaped for the listing, and it’s coming to the market with poor figures from the corona year (though this year’s guidance is significantly better)? As a model, one would think that if, for example, H1 figures were to be excellent, it would have been worth waiting until autumn in light of the figures (unless the fear of the listing boom drying up before then).
