Cardiff Property posts pre-tax profits of £2.7m for the year to the end of September- up from £2.6m last time.
Rental income increased to £580,000 from £577,00 and earnings per share rose to 195.3p from 191.3p.
Chairman Richard Wollenberg said: "During the period prior to the UK European Referendum vote the Thames Valley commercial property market enjoyed increased activity. The leave vote brought about uncertainty with commentators predicting falls in rental levels and capital values. Despite this, activity in the investment and occupational markets has been higher than expected with office, retail and industrial rents in parts of the Thames Valley showing small increases."
