Pivotal Announces KLDiscovery’s Third Quarter Results

• Net Loss improves 35% year-over-year to $11.3 million

• Adjusted EBITDA of $16.8 million surges 28% vs. year ago

• KLD updates 2019 and 2020 forecast due to delayed merger closing with Pivotal

New York, NY and McLean, VA, November 15, 2019 – Pivotal Acquisition Corp (NYSE: PVT) (“Pivotal”), a special purpose acquisition corporation, announced 2019 third quarter results of KLDiscovery (“KLD”), a leading global provider of electronic discovery, information governance and data recovery services.

Highlights for the Third Quarter of 2019

KLD achieved total quarterly revenue of $78.2 million for the quarter ended September 30, 2019, as revenue growth increased by 6% compared to the third quarter of 2018. Net loss for the quarter ended September 30, 2019 was $11.3 million, an improvement of 35% over the prior year period’s net loss of $17.4 million. Adjusted EBITDA was $16.8 million, a 28% increase over the prior year period’s adjusted EBITDA of $13.1 million.

Revenue for the nine months ended September 30, 2019 totaled $231.5 million, an increase of 6% compared to $219.2 million during the same period in 2018. Net loss for the nine months ended September 30, 2019 was $36.2 million, a solid improvement of 28% over the prior year period’s net loss of $50.6 million. Adjusted EBITDA for the nine months ended September 30, 2019 was $51.5 million, representing a 25% increase over the prior nine-month period’s adjusted EBITDA of $41.1 million.

“We achieved another very strong quarter of revenue growth in the third quarter as we continue to grow relationships with existing clients, add new customers and achieve cross-selling synergies from the integration of our acquisitions,” said Chris Weiler, Chief Executive Officer of KLDiscovery.

“KLDiscovery turned in an excellent quarter of top line growth and accelerated adjusted EBITDA,” said Jonathan Ledecky, Pivotal’s Chairman and Chief Executive Officer. “The management of KLDiscovery is looking forward to resuming its acquisition strategy in early 2020 upon completion of the proposed merger with Pivotal scheduled for December 2019.

2019 and 2020 Outlook

Due to the lengthy delay in the completion of the proposed merger with Pivotal, KLD is updating its outlook for the fiscal years ending December 31, 2019 and 2020. The closing delay of the merger with Pivotal originally announced in May 2019 has resulted in a slower than expected acquisition program in the second half of 2019. The impact of this closing delay has resulted in the original forecasted incremental revenue, operating profit, expense reduction synergies and operating efficiencies from these potential acquisitions to be pushed back by two full quarters.

Pivotal now reports that KLD’s full-year 2019 outlook revenue will be in a range of approximately $307-$310 million and Adjusted EBITDA will be in a range of approximately $67-$70 million due mainly to incremental technology expenses and a mix shift of more managed review revenue than anticipated. This compares to previous KLD guidance provided in May 2019 for fiscal year ending December 31, 2019 revenue of approximately $310 million and approximately $75 million in Adjusted EBITDA.

For the full-year 2020, KLD now expects revenue in the range of approximately $335-$355 million and Adjusted EBITDA in a range of approximately $80-$85 million. This guidance includes current trendline organic growth plus significant operating synergies and expense savings from the resumption of the Company’s acquisition program by the second quarter of 2020. The forecast includes $4 million of incremental public company costs for 2020 which have been revised as part of the merger process. This compares to previous guidance provided in May 2019 of approximately $347 million in revenue and approximately $92 million in Adjusted EBITDA. The previous guidance was based on a September 30, 2019 projected merger closing with Pivotal and the resumption of an acquisition program in the fourth quarter of fiscal 2019 which did not occur.

Further information about the Company can be found in the definitive proxy statement/prospectus, which was declared effective by the SEC on November 12, 2019. This guidance is subject to the risks and uncertainties described in the “Forward Looking Statements” below.

Participants in the Solicitation

Pivotal and KLD and their respective directors and executive officers, under SEC rules, may be deemed to be participants in the solicitation of proxies of Pivotal’s stockholders in connection with the proposed transaction. Investors and security holders may obtain more detailed information regarding the names and interests in the proposed transaction of Pivotal’s directors and officers in Pivotal’s filings with the SEC, including the definitive proxy statement/prospectus and Pivotal’s Annual Report on Form 10-K for the fiscal year ended December 31, 2018, which was filed with the SEC on April 1, 2019.

No Offer or Solicitation

This communication shall neither constitute an offer to sell or the solicitation of an offer to buy any securities, nor shall there be any sale of securities in any jurisdiction in which the offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction.

Use of Non-GAAP Financial Measures

KLD prepares audited financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”). KLD also discloses and discusses non-GAAP financial measures such as adjusted EBITDA. KLD believes that these measures are relevant and provide useful information to investors by providing a baseline for evaluation and comparing its operating performance against that of other companies in KLD’s industry.

The non-GAAP financial measures that KLD uses may not be comparable to similarly titled measures reported by other companies. Also, in the future, KLD may disclose different non-GAAP financial measures in order to help its investors meaningfully evaluate and compare its results of operations to its previously reported results of operations or to those of other companies in KLD’s industry. KLD also believes the use of non-GAAP financial measures reflects its ongoing operating performance because the isolation of non-cash charges, such as amortization and depreciation, and other items, such as interest, income taxes, management fees and equity compensation, acquisition and transaction costs, restructuring costs, systems establishment, and costs associated with strategic initiatives which are incurred outside the ordinary course of business, and provide information about KLD’s cost structure, that helps track its operating progress. In addition, KLD urges investors and potential investors to carefully review the GAAP financial information and compare with its adjusted EBITDA.

Adjusted EBITDA

KLD views adjusted EBITDA as an operating performance measure and as such, it believes that the most directly comparable GAAP financial measure is net loss. In calculating adjusted EBITDA, KLD excludes from net loss certain items that it believes are not reflective of KLD’s ongoing business and exclusion of these items allows KLD to provide additional analysis of the financial components of the day-to-day operation of its business. KLD has outlined below the type and scope of these exclusions.
