The AIM-listed financial services group reported a maiden pre-tax profit of £221,000, while underlying earnings (EBITDA) jumped 132% to £894,000 from £384,000 in 2017 and revenues climbed 47% to £28.8mln from £19.5mln.
The firm also said that it had seen a 41% increase in revenues generated by ongoing advisory business to £25.2mln, from £17.9mln in 2017.
While the company did not pay out a dividend, it said it had created distributable reserves of revenue, a prerequisite for the future payment of dividends.
The announcement followed an update in January where the group received "overwhelming support" from shareholders for its plan to use £23mln from its share premium account to wipe out its deficit, paving the way to start dividend payments.
In terms of its product range, Tavistock said it had launched three new ACUMEN funds (a portfolio comprising of a basket of exchange traded funds) as well as introducing US Dollar and Euro denominated share classes to facilitate the introduction of funds from overseas investors.
Tavistock shares were up 6.5% at 3.25p.
