Is Diversified Royalty stock a good buy?

The company's asset-light business model allows it to distribute a majority of its net income to shareholders as dividends. In the last two years, Diversified Royalty has increased its monthly dividends from $0.01833 per share to $0.02083 per share.

Its revenue has risen from $30.5 million in 2019 to $61.9 million in the last four quarters, while its operating income has more than doubled to $55.6 million in this period.

In the last six months, Diversified Royalty's weighted average organic royalty growth of its portfolio rose by 5% year over year. Its adjusted sales in the second quarter (Q2) rose by 17.2% year over year to $18.1 million, while distributable cash stood at $11.6 million, up 19% compared to the year-ago period. The company's payout ratio stood at 88.6%, which is reasonable given its revenue and cash flow growth.

The TSX dividend stock has a runway for growth

Diversified Royalty continues to acquire trademarks that should support its top-line and profitability growth in the future.

For example, it recently acquired the BarBurrito trademark in exchange for a fixed monthly payment equal to $8.3 million per annum. This payout will grow at a fixed rate of 4% per annum for the first seven years, after which it will fluctuate based on the gross sales of BarBurrito locations in the royalty pool.

Analysts tracking the TSX stock expect it to gain over 30%, given consensus price target estimates. If we include its dividend, cumulative returns may be closer to 38% in the next 12 months.
