ITEM 8.01 Other Events.

On August 28, 2015, FTI Consulting, Inc. (“FTI Consulting”) issued a press release announcing the results of its previously announced cash tender offer (the “Tender Offer”) to purchase any and all of its outstanding $400 million aggregate principal amount of 6  ³⁄₄% Senior Notes due 2020 (the “Notes”), which expired as of 5:00 p.m., New York City Time, on August 27, 2015 (the “Expiration Time”). As of the Expiration Time, a total of $192,897,000 aggregate principal amount of Notes had been validly tendered and not validly withdrawn in the Tender Offer. FTI Consulting has accepted all Notes validly tendered and not withdrawn and has paid the purchase price therefore.

In addition, on September 1, 2015, FTI Consulting issued a press release announcing that it has elected to redeem on October 1, 2015 the $207,103,000 aggregate principal amount of Notes that remained outstanding after the consummation of the Tender Offer.

Copies of the press releases are filed herewith as Exhibits 99.1 and 99.2, respectively, and are hereby incorporated by reference herein.

This Current Report on Form 8-K includes “forward-looking statements,” which involve uncertainties and risks. Forward-looking statements include statements concerning FTI Consulting’s plans, objectives, goals, strategies, future events, future revenues, future results and performance, expectations, plans or intentions relating to acquisitions and other matters, business trends and other information that is not historical, including statements regarding estimates of FTI Consulting’s future financial results. When used in this press release, words such as “expects,” “anticipates,” “plans,” “intends,” “believes,” “forecasts” and variations of such words or similar expressions are intended to identify forward-looking statements. All forward-looking statements are based upon FTI Consulting’s expectations at the time it makes them and various assumptions. FTI Consulting’s beliefs are expressed in good faith, and FTI Consulting believes there is a reasonable basis for them. However, there can be no assurance that management’s expectations and beliefs will be achieved, and actual events may differ materially from its expectations and beliefs. FTI Consulting is under no duty to update any of the forward-looking statements to conform such statements to actual results or events and do not intend to do so.
