Shares of Isle of Capri (NASDAQ:ISLE) are trading 7% higher today after releasing second-quarter earnings that topped forecasts, despite being weighed down by construction costs. Net income for the casino operator fell to $10.6 million from $13.6 million, but earnings of $0.34 beat estimates by a nickel on revenues that dropped slightly to $280.9 million.

For sports fans out there, we can just say that Isle of Capri is in a rebuilding year, sacrificing current performance for an overhaul that will ultimately strengthen the firm's competitive position. Renovations at the company's properties will curtail growth in the short term but will pay off after completion next spring.

Construction is now nearly complete at the Grand Palais Casino in Lake Charles, La., but a $79 million renovation at the Isle-Biloxi in Mississippi as well as a massive $95 million undertaking in Black Hawk, Colo., will both continue to substantially hamper operations until next year. Just as rival Argosy (NYSE:AGY) has devoted substantial resources to its crown jewel in Lawrenceburg, Ind., Isle of Capri's three projects will all boost key properties.

With $41.7 million in revenues last quarter, Lake Charles is hands down the firm's leading casino, and Black Hawk with $10.2 million in earnings before interest, taxes, depreciation, and amortization (EBITDA) is clearly the most profitable.

With the exception of Blackjack, whose rules and versions can vary widely from table to table, casino play is largely standardized. A $1 bet on my favorite roulette number -- 20 -- will return $35 whether my chips are played in a riverboat casino or Caesar's (NYSE:CZR) Palace. Therefore, it is not the tables and slots that distinguish a property and keep customers loyal, but everything else: the entertainment, the food, the décor, and the comps (not same-store sales, but all the freebies a casino extends to entice visitors and keep them happy).

Property renovations may take a bite out of earnings, but they are vital to increasing business. Competitor Pinnacle's (NYSE:PNK) Belterra, Ind., casino resort recently reported a 52.3% surge in earnings after the completion of a $37 million expansion project. Argosy just put the finishing touches on an immense, new Mediterranean-themed barge near Kansas City that helped revenues soar 58.2% higher, while Isle of Capri's nearby casino managed only a modest 4.2% increase.

Despite the ongoing fiasco over the apparent loss of a gaming license near Chicago, Isle of Capri's strategy of geographic diversity is sound. The company operates casinos in a broad range of markets spanning from Mississippi to Colorado and compared with more concentrated competitors has limited exposure to regional operating environment changes. Isle of Capri's revenues, earnings, and margins will likely be held in check temporarily, but every company in the industry at times must contend with construction disruptions and large capital expenditures for new projects. It is simply the price to pay for future growth.
