                                 Windar Photonics plc                              
                         (the "Company" or "Windar Photonics")                     

                                    Trading update                                 

    Windar Photonics plc (AIM:WPHO), the technology group that has developed a cost
    efficient and innovative Lidar wind sensor for use on electricity generating
    wind turbines, announces a trading update based on the Company's performance
    during the first five months of 2015.

    The Asian retrofit market is an important market for the Company in the near
    term. The Company has experienced delays primarily related to expanding and
    educating the service and installations team operated by our distribution
    partners in Asia. As a result we have seen an overall delay in expanding our
    installations and sales in this region during the first five months of 2015,
    which the directors expect to see continuing into the second half of the year.

    In order to assist our Asian distributor to address these issues and help
    address the local market that has shown considerable interest in the Company's
    Lidar system, the Company has established a representative office in Shanghai
    to provide local technical support to our distribution partner. With this
    support we expect these issues to be resolved, but the Directors anticipate
    that there will be a material revenue shortfall in this region for 2015,
    although sales in the rest of the world is anticipated to be in line with
    management's expectations. This will have a consequentially material adverse
    effect on the Group sales and losses for the current year ending 31 December
    2015. However, the Directors believe the issues are of a short term nature and
    remain confident of the outlook for sales in Asia in the mid to long term.

    The Company also announces that last month, Windar Photonics launched at the
    AWEA WindPower 2015 Expo in Orlando a new integrated control system, which
    combines with our WindEye™ Sensor product, in conjunction with the Danish
    company, KK Wind Solutions. With this new combined product offering, Windar
    Photonics is marketing a complete solution to the retrofit market whereby the
    WindEye™ Sensor will not only be focused on increased power generation but also
    load reductions on existing turbines in order to reduce maintenance costs and
    eventually increase the remaining lifetime of the turbines.

    Windar Photonics has received its first test order for one of these retrofit
    control systems from the US based company IQ Innovations LLC. Commenting on the
    development IQ Innovation's General Manager Thomas Johnsson said: "The Windar
    Photonics optimisation solution holds a lot of potential in regards to
    retrofitting, where it can help reduce life cycle costs for operations and
    maintenance, resulting in fewer stoppage days and less repair costs. The
    minimal maintenance complemented by the increased operation time makes the
    Windar Photonics optimisation solution very relevant from a return of
    investment perspective."

    Windar Photonics has also received its first test order for the newly developed
    4-beam Lidar system. The order was placed by an European wind turbine
    manufacturer and will be commissioned in Q3 this year. The 4-beam Lidar system
    has been developed for the wind turbine manufacturers in order to measure not
    only wind speed and direction but also wind shear, which is particularly
    relevant for the larger MW turbines which can come under considerable loads in
    certain winds. The 4-beam Lidar system will also be tested at the Danish
    Technical University in Denmark where the wind assessment team will be
    measuring actual load reduction and estimating the financial benefits of using
    the 4-beam Lidar system developed by Windar Photonics.

    Although the new Turbine Control Unit and the new 4-beam Lidar system are only
    expected to have a minor impact on the revenues for 2015, these two new
    business areas are expected to further underpin revenues in 2016 and beyond.
