On April 30, 2019, Forrester Research, Inc. issued a press release announcing its financial results for the quarter ended March 31, 2019.

Forrester believes that pro forma financial results provide investors with consistent and comparable information to aid in the understanding of Forrester’s ongoing business. Forrester uses pro forma financial information to manage its business, including use of pro forma financial results as the basis for setting targets for various compensation programs. Our pro forma presentation excludes the following, as well as their related tax effects:

Amortization of intangibles—we exclude the effect of the amortization of intangibles from our pro forma results in order to more consistently present our ongoing results of operations.

Fair value adjustment of deferred revenue – we exclude the reduction in revenue resulting from the fair value adjustment of pre-acquisition deferred revenue in order to more consistently present our ongoing results of operations.

Gains and losses from investments—we have consistently excluded both gains and losses related to our investments in non-marketable securities and sales of marketable securities from our pro forma results in order to keep quarter-over-quarter and year-over-year comparisons consistent.

Stock-based compensation expense—we exclude stock-based compensation from our pro forma results in order to keep quarter-over-quarter and year-over-year comparisons consistent.

Acquisition and integration costs—we exclude the direct costs of acquiring and integrating companies from our pro forma results in order to keep quarter-over-quarter and year-over-year comparisons consistent.

However, these measures should be considered in addition to, not as a substitute for, or superior to, operating income or other measures of financial performance prepared in accordance with generally accepted accounting principles as more fully discussed in our financial statements and filings with the Securities and Exchange Commission.

FOR IMMEDIATE RELEASE

Forrester Research Reports 2019 First-Quarter Financial Results

Cambridge, Mass., April 30, 2019 . . . Forrester Research, Inc. (Nasdaq: FORR) today announced its 2019 first-quarter financial results.

First-Quarter Financial Performance

Total revenues were $100.6 million for the first quarter of 2019, compared with $77.7 million for the first quarter of 2018. Research revenues increased 33%, and advisory services and events revenues increased 23%, compared with the first quarter of 2018. Pro forma revenues, which exclude the fair value adjustment to deferred revenue from the acquisition of SiriusDecisions, were $104.6 million for the first quarter of 2019, with $72.4 million from research services and $32.2 million from advisory services and events.

On a GAAP basis, net loss was $13.3 million, or $0.73 per diluted share, for the first quarter of 2019, compared with a net loss of $1.7 million, or $0.10 per diluted share, for the same period in 2018.

On a pro forma basis, net income was $1.6 million, or $0.08 per diluted share, for the first quarter of 2019, which reflects a pro forma effective tax rate of 31%. Pro forma net income excludes stock-based compensation of $2.7 million, amortization of acquisition-related intangible assets of $6.2 million, acquisition-related deferred revenue fair value adjustment of $3.9 million, and acquisition and integration costs of $3.0 million. This compares with a pro forma net loss of $0.2 million, or $0.01 per diluted share, for the same period in 2018, which reflects a pro forma tax rate of 31%. Pro forma net loss for the first quarter of 2018 excludes stock-based compensation of $2.0 million and amortization of acquisition-related intangible assets of $0.2 million.

“Forrester was at the upper end of pro forma revenue guidance and exceeded pro forma operating margin and EPS targets for the first quarter,” said George F. Colony, Forrester’s chairman and chief executive officer. “We continued the momentum that we had from 2018 with a great start in Q1. At the same time, we continue to make progress with the integration of SiriusDecisions — we are on track for a successful completion and remain bullish on realizing the value from the acquisition.”

Forrester is providing second-quarter 2019 financial guidance as follows:

Second-Quarter 2019 (GAAP):
