Last month, I hauled the family down to Destin, Florida for some overdue beach relaxation. That’s about 1,000 miles round-trip. Add it to a long list of Clark Griswold-style cross-country treks we’ve taken over the years. Wisconsin Dells. Mackinac Island. Myrtle Beach.

It’s a long way down that holiday road.

I can’t tell you exactly how many interstate exits we encountered along the way, but we must have taken pit stops at about half of them for fuel, snacks and/or bathroom breaks.

Years ago, weary travelers had no clue what amenities could be found at the next crossroads. Of course, we have a wealth of information at our fingertips these days. GPS-enabled navigation systems not only provide turn-by-turn directions but a detailed list of food, gas and lodging options at the push of a button.

But even with digital assistance, travelers still rely on those faithful blue signs along the way. You know, the ones that display the logos of nearby restaurants, hotels and gas stations. Hungry? One glance and you will know there’s a Wendy’s, Chipotle and Subway coming up just a mile or two down the road.

For most people, these signs are purely informational. For me, they are also inspirational. As we sped across I-10, I couldn’t help but see dollar signs every few miles – because those blue signs generate revenues morning, noon, and night.

After all, advertisers like Taco Bell owner Yum Brands! (NSDQ: YUM) must pay to display their logos. And one company is on the receiving end of all those thousands of checks. It has been awarded exclusive logo signage contracts by two dozen states – including every single exit from the Gulf Coast to the Eastern Seaboard.

I love those two words.

Exclusive means other competitors are excluded, so one party enjoys all the spoils. We have another term for that: monopoly.
Contract implies a written agreement that will stay in force for a predetermined period, generally five to ten years in this case.

What does all that mean for investors? Well, these lucrative contracts support a quarterly dividend distribution that has raced from zero in 2014 to $1.55 per share today. The payout has doubled just since 2021, throwing off a hefty yield of 5.1% – higher than 95% of the S&P 500.

I’m talking about Lamar Advertising (NSDQ: LAMR). As we speak, the company operates 45,000 exit signs that contain 150,000+ corporate logos. Incidentally, only 25 states have opened signage bidding to private enterprise – and Lamar has won 23 of these licenses.

This same company also owns roadside billboards throughout North America, many of which are strategically located in major metro arteries and thoroughfares and command top-dollar rates.

There are only a few large-scale players here. Tall barriers to entry effectively keep potential competitors outside the gates. Picture a metaphorical chain-link fence topped with regulatory barbed wire. The Highway Beautification Act of 1965 placed strict limits on new installations, thereby protecting the incumbent market leaders.

Aside from restrictive federal laws, all 50 states have their own individual laws limiting the erection of new roadside billboards — which means that in many cities, competition isn’t just discouraged, but illegal.

In this environment, acquisition is the easiest path to growth. Lamar has been assimilating smaller regional rivals and consolidating market share for decades. Just last month, it gobbled up Verde Outdoor, adding another 1,500 highway billboards from Arizona to New Jersey. That brings the grand total to 365,000 displays across the U.S. and Canada.

For context, the next closest competitor (Outfront Media) has just 40,000. Lamar has a greater reach than the next 10 biggest rivals combined. The newest division is aimed at municipal mass transit advertising. Ever stopped to notice splashy ads placed on city buses and inside airport terminals? Odds are good that Lamar was involved.

The company has cultivated a broad base 40,000 local, regional and national advertising customers. The diverse roster comprises banks, retailers, hotels, casinos, telecoms and many other groups. Some of the largest clients include Burger King and AT&T, but customer concentration is a non-issue, considering no individual tenant represents more than 2% of sales.

Lamar has recruited an army of 900 account executives deployed out in the field. These professionals make sure that the billboards stay rented, but it isn’t a hard sell. With motorists passing by 24 hours a day (particularly in heavily trafficked routes), advertisers can reach 1,000 adults for less than $4.00 — a cost-effective advertising medium compared with radio and television.

Strong returns on investment (ROI) ensure that few billboards stay vacant long.

Revenues are on track to top $2.2 billion this year. And this light business doesn’t require much in the way of operating overhead. The signs do all the work — and they don’t have salaries or healthcare benefits. That helps explain why Lamar routinely converts every dollar of revenues into nearly 40 cents of operating cash flow.

At the halfway mark of 2025, adjusted funds from operations (AFFO) of $389 million ($3.81 per share) is tracking about 5% ahead of last year’s pace. This key metric has been climbing at a steady 7% pace over the past decade.

Looking ahead, I am optimistic about the ongoing transition to digital billboards, which broadcast multiple messages on the same board (ad spots change every six to eight seconds) and fetch premium rental rates for the most desirable time slots. Only 3% of the firm’s total billboard inventory has been converted to digital, yet these displays account for one-third of all billboard revenues.

I also like the recent sale of Lamar’s minority ownership in Vistar Media. It took a 20% stake in the out-of-home advertising network for $30 million in 2021 and just cashed out a $120 million windfall on the transaction, strengthening the balance sheet.

If you’re in the income investing lane, LAMR might be well worth a quick visit.
