Here is a new company report on Nightingale from Antti & Antti at Inderes following the latest news 
During the beginning of the year, Nightingale has announced three new projects or partnerships. In our assessment, these new ventures are pilot-type projects, and their potential commercial significance will only become clear in the medium term. As no significant new information regarding major new projects or the progress of ongoing commercialization has been received during the early part of the year, we are revising our forecasts for the coming years and, accordingly, lowering our target price to EUR 1.4 (prev. EUR 1.7). The share price has declined very sharply since the financial statements report, which has improved the risk/reward ratio. Consequently, we are upgrading our recommendation to Buy (prev. Accumulate).
