News that the Internal Revenue Service was reviewing what constitutes a U.S. real estate investment trust left a diverse collection of companies less sure about their future tax treatment--and less valuable in the stock market Friday.

Shares of network facility operator Equinix Inc. (EQIX), billboard owner Lamar Advertising Co. (LAMR) and car-auction lot owner Copart Inc. (CPRT) all fell--on an otherwise up day for the market--after document manager Iron Mountain Inc. (IRM) revealed that a new IRS working group was reviewing legal standards for REITs.

The news raised the possibility that the IRS may make it tougher for those companies seeking to change their tax status to a REIT, which allows companies to largely avoid corporate taxes if they pay most of their taxable income to investors through dividends.

An IRS spokesman had no immediate comment on the agency's new working group.

Iron Mountain is one of several nontraditional property owners that have asked the IRS for REIT treatment. The Boston storage company has argued its document-racking structures qualify as real estate and intends to convert to a REIT next year. Iron Mountain shares recently fell 17% to $28.67.

Analysts cautioned, however, that the risk to each company's REIT status varies widely depending on the kind of assets they own.

"Private letter rulings are binding agreements between the IRS and the requesting party, and as a result do not create precedence," Jefferies analyst Omotayo Okusanya wrote. "That said, we would be surprised if companies looking to become REITs with previously approved 'REIT-able' asset classes did not" win IRS nods.

Establised asset classes bode well for network facility operator Equinix, which sought REIT status in September after similar data-center landlords such as Digital Realty Trust Inc. (DLR) secured the same status.

Equinix acknowledged that the IRS working group could affect it, but said it "continues to believe, based on both existing legal precedent and the fact that other data center companies currently operate as REITs, that its data center assets constitute real estate for REIT purposes."

Shares of Equinix fell 5.5% to $192.72.

As for Lamar Advertising, Mr. Okusanya said the IRS already eyes outdoor advertisers on a case-by-case basis.

For its part, Lamar remained confident. "Based on its discussions with the IRS, the company has no reason to conclude that it will not be in a position to complete the previously announced plan," Lamar said in a filing with the U.S. Securities and Exchange Commission. The outdoor advertiser intends to make its conversion effective next year.

Nonetheless, shares of Lamar still slumped, sliding 4.1% to $43.66.

The process also creates uncertainty for the outdoor advertising business of CBS Corp. (CBS), which the media company took steps to divest. CBS said earlier this year that it could convert to a REIT in 2014.

CBS shares fell 1.1% to $48.30.

Without so much as a similar precedent, companies with more "unusual" assets could face a bigger challenge, Mr. Okusanya said, noting a lack of precedent for companies like Copart as well as Waste Management Inc. (WM) and Republic Services Inc. (RSG), which own landfills.

Copart shares declined 6.3% to $32.25.

Delays caused by the IRS review could also set back companies' performance even if they eventually receive the agency's approval. Analysts noted the wait wouldn't affect Equinix as seriously as companies with earlier deadlines, though--it aims to complete the process by 2015, providing plenty of time to deal with working group questions.

"At this point, we see little risk on this front given the company's target date for conversion," Stifel Nicolaus analyst Todd Weller wrote in a note to clients, adding its case is helped by the fact that similar data-center operators have already won the tax treatment Equinix is seeking.
