Noel Lamb, Chairman of Rockwood Strategic plc, commented:

"Further positive gains and growth in NAV during the year mark another year of progress for Rockwood Strategic, building on the impressive medium-term record. Whilst the conflict in Iran temporarily dampened our full year performance, post period end gains have been strong, supported by renewed corporate activity in the portfolio".

Richard Staveley, Fund Manager, Rockwood Asset Management said:

"Confidence in the portfolio has rarely been higher as a significant number of our investments are delivering on our investment theses with improved profitability, returns and growth despite a soggy domestic economy. We anticipate a range of positive company specific catalysts to emerge in the year ahead, driving further NAV growth. We have an abundance of opportunities in our investment pipeline, in which to recycle significant realised gains from takeovers and the proceeds from Rockwood issuance, due to the exceptional value on offer in UK smaller companies. To paraphrase Buffett; we have a bucket, not a thimble and it is raining gold in UK small companies currently".
