ADMISSION TO TRADING ON AIM AND FIRST DAY OF DEALINGS

Dianomi plc ("Dianomi", the "Company" and together with its subsidiary undertakings, the "Group") a leading provider of native digital advertising services to premium clients in the Financial Services and Business sectors, is pleased to announce the admission ("the "Admission") of its entire issued and to be issued ordinary share capital to trading on the AIM Market of the London Stock Exchange ("AIM"). Admission will occur at 8.00 a.m. today, under the ticker "DNM" and the ISIN: GB00BLH32M40.

Following a successful and significantly oversubscribed placing of, in aggregate, 13,553,112 ordinary shares of £0.002 each ("Ordinary Shares") comprising new Ordinary Shares (the "New Shares") and existing Ordinary Shares (the "Sale Shares"), approximately £37.0 million (before expenses) was raised for the Company and the Selling Shareholders (the "Placing").

Panmure Gordon is acting as Nominated Adviser, sole broker and sole bookrunner in relation to the Placing and Admission.

Key highlights

·    The Placing, which is conditional upon, amongst other things, Admission, comprises a placing of 1,831,501 New Shares and 11,721,611 Sale Shares, in each case, at 273 pence per Ordinary Share (the "Placing Price") with institutional and other investors.

·    Based on the Placing Price, the market capitalisation of the Company will be approximately £82.0 million on Admission.

·    On Admission, the Company will have 30,027,971 Ordinary Shares in issue.

·    The Placing of the New Shares has raised gross proceeds of approximately £5.0 million for the Company.

·    The Placing of the Sale Shares has raised gross proceeds of approximately £32.0 million for the Selling Shareholders.

·    As the Placing attracted strong support from institutional investors, the size of the Placing was upscaled and remained significantly over-subscribed.

·    On Admission, the Group's founders will own approximately 28 per cent. of the issued Ordinary Shares.

·    The Company intends to use the net proceeds of the Placing of the New Shares to expedite the Group's organic growth through expanding the Group's sales and marketing capabilities in North America and EMEA and expanding into other verticals, most imminently into the premium Lifestyle content vertical.

Rupert Hodson, Chief Executive Officer of Dianomi, said:

"The positive response from investors to Dianomi's IPO and future plans has been very encouraging and we are delighted to welcome our new shareholders. Demand for native digital advertising has grown substantially over the last 5 years and this is set to continue, however, a key focus for advertisers is on delivering premium advertising content that people want to see in publications people want to read, an area where Dianomi excels and so we are looking forward to the next stage in Dianomi's development."
