Enreq, which acquires and consolidates companies which provide specialist services to the upstream oil and gas market, reported a loss before tax of $11.5m for the year to end of March 2014, up from a loss of $0.6m a year earlier, reflecting a $9.8m impairment charge of goodwill and intangible assets related to the acquisition of oil technology firm KMS.Nevertheless, the firm delivered a like-for-like increase in revenues of 24% to $24.6m during the year, resulting in an adjusted earnings per share of $0.22, compared to the prior year's loss of $0.8.Perry described the results as "pleasing", adding that the company would "continue to focus on growing the drilling technology business organically and through the addition of complementary product lines".Top Director BuysEnteq Upstream (NTQ) Director name: Mr Martin PerryAmount purchased: 200,000 @ 37.00p Value: £74,000Volex (VLX) Director name: Mr Christoph EisenhardtAmount purchased: 63,274 @ 79.02p Value: £49,999Anglo American (AAL) Director name: Mr Byron GroteAmount purchased: 1,250 @ 1,401.54p Value: £17,519Top Director SellsGood Energy Group (GOOD) Director name: Mr Garry PeagamAmount sold: 10,000 @ 230.00p Value: £23,000NR
