MGM Resorts heads into its third-quarter report with an odd mismatch. Management closed its last call sounding more confident than at any point in the past year, with Las Vegas finally growing again and every other segment posting records or near records. Yet the stock has fallen 38.1% since that report while the S&P 500 gained about 4%. At $28.47, shares sit just above their post-earnings low of $27.94 and roughly 28% below the 200-day moving average. The October 28 release, due after the close, has to show whether the operating story still holds or whether the market has spotted cracks that management has not yet acknowledged.

The Street is not asking for much. Consensus calls for earnings of $0.25 per share on revenue of $4.30 billion, which works out to growth of about 4% and 1% from a year ago. That bar looks undemanding given the comparison. The year-ago quarter was the low point of MGM's Las Vegas reset, when Strip EBITDA fell about $130 million and net revenue dropped 7%. Matching that weak base with only 1.2% top-line growth implies analysts expect little carryover from the momentum management described. MGM offers no formal consolidated guidance. Its only reaffirmed targets were $300 million to $350 million of BetMGM EBITDA for the year and smaller digital losses than last year.

Las Vegas is the swing factor. The Strip delivered its second straight quarter of revenue growth last period and its first EBITDA gain in a while, about $25 million. But some of that came from favorable hold, worth tens of millions of dollars. Management would only promise revenue growth with certainty and framed EBITDA growth as a longer-term goal. A clean quarter would show Strip EBITDA up year over year on normal hold, helped by remodeled MGM Grand rooms, a group and convention mix near 20%, and strong catering revenue. Room pricing is the other test. RevPAR was still down last quarter, and Luxor and Excalibur remained soft midweek. Evidence that the all-inclusive offer at those properties is drawing new customers at accretive prices, beyond weekends, would support the claim that the value end of the portfolio is mending.

Macau needs to confirm that June's World Cup slump was temporary. MGM China's share climbed to 16.4% last quarter, and management said July volumes had returned to first-quarter levels. Holding share near that level for the full quarter would back up the recovery story. Regionals have set records so often that anything short of continued slot strength at Borgata and Beau Rivage would stand out. Digital is murkier. Revenue grew 20%, but the EBITDA loss widened to $31 million because of heavy spending in Brazil, a market management called fluid. A narrower loss would help make the full-year promise of smaller losses believable.

Sentiment has cooled noticeably, with bearish readings rising to 61.3% from 49.4% before the last report. That makes capital allocation and the People, Inc. takeover offer from Barry Diller unusually important. A special committee is reviewing the offer, and management declined to discuss it last quarter, so disclosure may again be thin. Buybacks slowed to $164 million at about $37 a share. With the stock now far below that price, whether MGM steps up repurchases, or explains why it cannot during the review, will say a lot about how the board views value.

In the end, the report turns on one question: can Las Vegas grow EBITDA without help from the tables? If the Strip shows underlying profit growth on top of an easy comparison, the stock's collapse will look disconnected from the business. If growth is mostly hold, mix, or one-time items, the market's skepticism will appear justified.
