Highlights for the third quarter of 2021:

“We are very pleased with our third-quarter results, highlighted by record performance in a number of areas. The third quarter represented a significant tipping point in our strategic evolution; for the first time in the Company’s history, both within the quarter and on a trailing-four-quarter basis, net sales from software solutions exceeded net sales of print and distribution, as we continue to execute against our ‘44 in 24’ strategy. This shift to a more profitable sales mix, which we expect to continue going forward, is a cornerstone of our transformation, and contributed significantly to our record high quarterly Adjusted EBITDA, Adjusted EBITDA margin, and Free Cash Flow,” said Daniel N. Leib, DFIN’s president and chief executive officer.

Leib continued, “We remain encouraged by the continued strong demand for our compliance software, featuring our ActiveDisclosure and Arc Suite products, as well as for our transactional software, Venue. Robust M&A activity within the capital markets contributed to record-high quarterly Venue sales, while growth of ActiveDisclosure sales accelerated in the third quarter, driven by client transitions to the new ActiveDisclosure platform and new client wins. Similarly, we achieved nearly 25% sales growth in our Arc Suite offering, primarily driven by client adoptions of our Total Compliance Management solution, which we rolled out earlier this year. Our continued focus on growing our software solutions, across multiple transactional and compliance use cases, is driving a higher adoption of our software products.”

“We experienced continued momentum in the transactional market heading into the third quarter, with the level of activity accelerating as the quarter progressed, especially in the IPO market. In addition, we benefited from strong de-SPAC activity, as the pipeline of clients we gained from SPAC transactions actively sought out acquisitions in the third quarter. Our strong market position enabled us to capture a significant portion of this activity, resulting in a 49% year-over-year increase in our transactional sales,” Leib concluded.

Net Sales

Net sales in the third quarter of 2021 were $247.7 million, an increase of $38.2 million, or 18.2%, from the third quarter of 2020. Net sales increased primarily due to higher capital markets transactional and compliance volume and growth in software solutions, partially offset by lower print and distribution volume as a result of the impact of SEC Rules 30e-3 and 498A eliminating print requirements.

Net Earnings

For the third quarter of 2021, net earnings were $42.2 million, or $1.22 per diluted share, as compared to $7.1 million, or $0.21 per diluted share, in the third quarter of 2020. Net earnings in the third quarter of 2021 included after-tax charges of $4.9 million, or $0.14 per diluted share, primarily due to share-based compensation expense and restructuring, impairment and other charges, net. Net earnings in the third quarter of 2020 included after-tax charges of $14.4 million, or $0.42 per diluted share, primarily due to restructuring, impairment and other charges, net, estimated multiemployer pension plan obligations arising from the bankruptcy of LSC Communications, Inc. and share-based compensation expense.

Adjusted EBITDA and Non-GAAP Net Earnings

For the third quarter of 2021, Adjusted EBITDA was $82.5 million, an increase of $34.9 million as compared to the third quarter of 2020. For the third quarter of 2021, Adjusted EBITDA margin was 33.3%, an improvement of approximately 1,060 basis points as compared to the third quarter of 2020, primarily driven by a favorable sales mix and cost control initiatives, partially offset by higher incentive compensation expense.

For the third quarter of 2021, non-GAAP net earnings were $47.1 million, or $1.36 per diluted share, up from $21.5 million, or $0.63 per diluted share, in the third quarter of 2020.

Reconciliations of net earnings to Adjusted EBITDA, Adjusted EBITDA margin and non-GAAP net earnings are presented in the attached tables.

Regulatory Impacts

The Company previously disclosed in a Current Report on Form 8-K on July 22, 2020, that the implementation of SEC Rule 30e-3 (elimination or reduction of print annual and semi-annual reports), Rule 498A (elimination or reduction of print summary prospectus) and the Company’s exiting of certain printing and distribution relationships were expected to reduce the Company’s print-related 2021 net sales by approximately $130 million to $140 million, with the associated reduction in net earnings and Adjusted EBITDA of approximately $4 million to $7 million and approximately $5 million to $10 million, respectively, in 2021.

The Company now expects 2021 reductions to net sales, net earnings and Adjusted EBITDA to be approximately $110 million, $4 million and $5 million, respectively. The Company expects the remaining impact to occur in 2022, with an expected reduction in net sales, net earnings and Adjusted EBTIDA of approximately $30 million, $2 million and $3 million, respectively. In aggregate, the expected impacts to net sales, net earnings and Adjusted EBITDA are in line with previous guidance.

Use of Non-GAAP Information

This news release contains certain non-GAAP financial measures, including non-GAAP gross profit, non-GAAP selling, general, and administrative expenses (“SG&A”), non-GAAP income from operations, non-GAAP operating margin, Adjusted EBITDA, Adjusted EBITDA margin, non-GAAP effective tax rate, non-GAAP net earnings, non-GAAP diluted earnings per share, Free Cash Flow and organic net sales. The Company believes that these non-GAAP financial measures, when presented in conjunction with comparable GAAP measures, provide useful information about the Company’s operating results and liquidity and enhance the overall ability to assess the Company’s financial performance. The Company uses these measures, together with other measures of performance under GAAP, to compare the relative performance of operations in planning, budgeting and reviewing the performance of its business.

The Company’s non-GAAP statement of operations measures, which include non-GAAP gross profit, non-GAAP SG&A, non-GAAP SG&A as % of total net sales, non-GAAP income from operations, non-GAAP operating margin, Adjusted EBITDA, Adjusted EBITDA margin, non-GAAP effective tax rate, non-GAAP net earnings and non-GAAP diluted earnings per share, are adjusted to exclude the impact of certain costs, expenses, gains and losses and other specified items that management believes are not indicative of our ongoing operations. These adjusted measures exclude the impact of expenses associated with the Company’s COVID-19 related recoveries and expenses, LSC multiemployer pension plans obligation, pension settlement charges, non-income tax charges (income), net, accelerated rent expense, share-based compensation and eliminate potential differences in results of operations between periods caused by factors such as historic cost and age of assets, financing and capital structures, taxation positions or regimes, restructuring, impairment and other charges and gain or loss on certain equity investments and asset sales.

Free Cash Flow is a non-GAAP financial measure and is defined by the Company as net cash flow provided by operating activities less capital expenditures. By adjusting for the level of capital investment in operations, the Company believes that free cash flow can provide useful additional basis for understanding the Company’s ability to generate cash after capital investment and provides a comparison to peers with differing capital intensity.

Organic net sales is a non-GAAP financial measure and is defined by the Company as reported net sales adjusted for the changes in foreign currency exchange rates.

These non-GAAP financial measures should be considered in addition to, not a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. In addition, these measures are defined differently by different companies in our industry and, accordingly, such measures may not be comparable to similarly-titled measures of other companies.

Use of Forward-Looking Statements

This news release includes certain "forward-looking statements" within the meaning of, and subject to the safe harbor created by, Section 21E of the Securities Exchange Act of 1934, as amended, with respect to the business, strategy and plans of DFIN and its expectations relating to future financial condition and performance. Statements that are not historical facts, including statements about DFIN management’s beliefs and expectations, are forward-looking statements. Words such as "believes," "anticipates," "estimates," "expects," "intends," "aims," "potential," "will," "would," "could," "considered," "likely," "estimate" and variations of these words and similar future or conditional expressions are intended to identify forward-looking statements but are not the exclusive means of identifying such statements. While DFIN believes these expectations, assumptions, estimates and projections are reasonable, such forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which are beyond DFIN’s control. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend upon future circumstances that may or may not occur. Actual results may differ materially from DFIN’s current expectations depending upon a number of factors affecting the business and risks associated with the performance of the business. These factors include such risks and uncertainties detailed in DFIN periodic public filings with the SEC, including but not limited to those discussed under "Risk Factors" in DFIN's Form 10-K for the fiscal year ended December 31, 2020, those discussed under “Cautionary Statement” in DFIN’s quarterly Form 10-Q filings, and in other investor communications of DFIN’s from time to time. DFIN does not undertake to and specifically declines any obligation to publicly release the results of any revisions to these forward-looking statements that may be made to reflect future events or circumstances after the date of such statement or to reflect the occurrence of anticipated or unanticipated events.
