Reaffirming Full-Year Outlook

Announces Review of Strategic Alternatives to Maximize Shareholder ValueEnters into Definitive Agreement to Acquire Edtech Provider VKidz

DALLAS, May 14, 2018 (GLOBE NEWSWIRE) -- Cambium Learning® Group, Inc. (Nasdaq:ABCD) (the "Company"), a leading educational technology solutions company committed to helping all students reach their full potential, announced today financial results for its first quarter ended March 31, 2018. The Company also announced that it has initiated a review of strategic alternatives to maximize shareholder value and entered into a definitive agreement to acquire VKIDZ Holdings Inc., a Florida-based award-winning edtech company providing curriculum and supplementary programs to homeschool families and elementary schools.

FIRST QUARTER 2018 RESULTS

“Cambium Learning Group delivered solid first quarter results, with company-wide growth compared to prior year first quarter in Bookings, revenues, Cash Income and net income. We are on track in building our pipeline toward the back-to-school selling season, and our full-year outlook remains unchanged. We are also proud that our technology-enabled solutions were honored with the highest number of BESSIE awards of any contender,” said John Campbell, Chief Executive Officer. “While the first quarter of any year is seasonally our lowest-volume period and does not generally serve as an indicator of performance, we are off to a strong start in terms of both our first quarter results and strategically, with our development, marketing and sales initiatives leading up to the important back-to-school period. We continue to execute our strategy to drive top-line growth with our SaaS solutions.”

Financial Snapshot

For the quarter ended March 31, 2018, the Company reported the following financial results:

Three Months Ended March 31, (in millions) 2018 2017 $ Change --------- --------- ------- GAAP net revenues $ 36.6 $ 36.0 $ 0.6 GAAP net income 2.6 2.5 0.1 Net income margin % 7 % 7 % EBITDA 8.5 8.7 (0.2 ) Adjusted EBITDA 8.9 9.0 (0.1 ) Adjusted EBITDA margin % 24 % 25 % Bookings $ 19.9 $ 19.1 $ 0.7 Cash income (10.6 ) (10.8 ) 0.2 Cash income margin % (53 )% (57 )%

First Quarter 2018 Financial Highlights

-- GAAP net revenues for the first quarter of 2018 increased by $0.6 million, or 2%, to $36.6 million compared with $36.0 million in 2017. GAAP net revenues by segment for the quarter ended March 31, 2018, and the change from the same period of 2017, were as follows: o Learning A-Z - $19.1 million, increased $1.0 million or 5% o ExploreLearning - $7.5 million, increased $0.7 million or 11% o Voyager Sopris Learning - $10.0 million, decreased $(1.0) million or (9)%.

-- Bookings for the first quarter of 2018 increased by 4% to $19.9 million, compared with $19.1 million in the first quarter of 2017, with growth in the ExploreLearning and Voyager Sopris Learning segments partially offset by a slight decrease in the Learning A-Z segment.

-- The Company reported GAAP net income of $2.6 million during the first quarter of 2018, increasing $0.1 million compared to net income of $2.5 million during the first quarter of 2017. -- Adjusted EBITDA was $8.9 million, decreasing $0.1 million from $9.0 million in 2017, with the growth in GAAP net revenues in the first quarter more than offset by strategic investments made to development, marketing and sales initiatives to support full-year and long-term growth of the Company’s technology solutions. -- Net interest expense was $0.8 million for the first quarter of 2018, down $0.4 million from the first quarter of 2017 as a result of the scheduled debt amortization payments and voluntary prepayments made during 2017. -- The Company’s effective tax rate for the first quarter of 2018 is higher than the effective tax rate for the first quarter of 2017 as a result of reducing the valuation allowance against most of the Company’s deferred tax assets in the fourth quarter of 2017.

-- Cash Income was $(10.6) million for the first quarter of 2018 compared to Cash Income of $(10.8) million for the first quarter of 2017. Capital expenditures totaled $4.0 million in the first quarter of 2018 versus $4.5 million in the first quarter of 2017.

-- The Company had cash and cash equivalents of $4.5 million at March 31, 2018. For the quarter ended March 31, 2018, cash used in operations was $6.2 million, cash used in investing activities was $4.0 million, and cash provided by financing activities was $6.2 million. At March 31, 2018, the principal amount of term loans outstanding was $47.1 million, the revolving credit facility outstanding was $7.0 million and there was $22.8 million available under the revolving credit facility.

-- The Company's technology-enabled products continue to receive industry recognition. Cambium Learning Group was recently awarded 10 Best Educational Software (BESSIE) awards from ComputED Gazette, more than any other company.

First Quarter 2018 Segment Results

Net Revenues, Bookings, Net Income, and Cash Income changes by segment for the three months ended March 31, 2018, compared to the same period of 2017 were as follows:

Q1 - 2018 % Change Net BookinNet Cash Revenugs IncomeIncome es ----- ----- ----- ------- Learning A-Z 5 % (3 )% — % (136 )% ExploreLearning 11 % 10 % (4 )% (42 )% Voyager Sopris Learning (9 )% 12 % 34 % 49 % Shared Services (1 )% (9 )% Cambium Learning Group, Inc. 2 % 4 % 3 % 2 %

2018 Outlook

Mr. Campbell stated, “In 2018, we are focused on driving Bookings growth of higher-margin SaaS solutions and making careful investments in development, marketing and sales, coupled with strong expense discipline, to drive expansion in Cash Income, Adjusted EBITDA, cash flow generation, and long-term value delivery to our stakeholders. Cambium Learning’s competitive edge centers on our personalized, adaptive, scalable, technology-based solutions that are proven to achieve results in the classroom and can change the trajectory of students’ lives. We are executing well to deliver a strong year and we are reaffirming our outlook.”

Management's outlook for company-wide 2018 Bookings growth at a higher percentage than 2017, with most of the growth expected in the second half of the year during the Company's seasonally strong periods, is unchanged. Cambium Learning Group's business is highly seasonal, with Bookings historically peaking during the third quarter, which represents by far the preponderance of Bookings, revenue and income each year.

The Company continues to expect its 2018 Bookings growth to be driven by its two 100% digital subscription businesses Learning A-Z and ExploreLearning. Voyager Sopris Learning is expected to build on the momentum of the LANGUAGE! Live solution and continue to make progress on repositioning the segment's role in the intervention marketplace.

Capital expenditures in 2018 are expected to be roughly consistent with 2017 and the Company expects growth in its Cash Income margin from 2017, with the impact of spending on strategic investments in its technology subscription products offset by the ongoing benefit of the transition in mix to these higher margin product lines. The Company continues to expect to generate enough cash during the year from normal operations that would enable it to be substantially debt free by the end of 2018. The Company will assess the impact of expected cash expenditures on the strategic alternatives process and the VKidz acquisition as the year progresses.

REVIEW OF STRATEGIC ALTERNATIVES

The Company announced today that it has initiated a review of strategic alternatives to maximize shareholder value. Such strategic alternatives could include a sale of the Company or a sale of a division or divisions thereof, a strategic merger, a business combination or continuing as a standalone entity executing on its business plan. The Company has engaged Macquarie Capital as financial advisor and Lowenstein Sandler LLP as legal advisor to assist in its review.

Mr. Campbell stated, “We remain confident in our ability to execute on our strategic plan and in the significant growth opportunities available to us. At the same time, management and our Board believe it is in the best interest of shareholders to conduct a thorough evaluation of strategic opportunities that could accelerate value recognition or unlock additional value.”

The Company has not set a definitive timetable for completion of its review of strategic alternatives, nor has it made any decisions related to any such strategic alternative at this time, and there can be no assurances that the process will result in any transaction being announced or completed in the future. The Company does not intend to make any further announcements related to its review unless and until its Board of Directors has approved a specific transaction or otherwise determined that further disclosure is appropriate.

VKIDZ TRANSACTION

Cambium Learning Group today announced a definitive agreement to acquire VKIDZ Holdings Inc. (“VKidz”), an award winning Florida-based edtech company dedicated to helping deliver the best education to students using digital solutions. Organized in two business units, VKidz serves both school systems and homeschooling families with 100% digital, 100% subscription, innovative, research-based educational products. The Company believes VKidz is an exceptional fit with its current operations, it will provide attractive cross selling opportunities, and it will expand Cambium's total addressable market. The acquisition is another step in Cambium’s strategy of being the leading provider of state of the art digital subscription solutions that make a difference in the lives of students.

Under the terms of the agreement, the purchase price will include issuance of 6.7 million shares of Cambium Learning Group common stock to the sellers, plus payment of outstanding debt of VKidz on the consummation date of the transaction. In 2017, VKidz had Bookings of approximately $21.1 million and Cash Income of approximately $5.7 million. At March 31, 2018, VKidz had debt principal outstanding of $20.2 million and cash of $1.3 million. The Company expects the acquisition to be immediately accretive.

The acquisition is expected to be consummated, subject to all applicable approvals, after completion of the Company’s review of strategic alternatives. The terms of the agreement provide the Company the right to terminate the agreement prior to consummation.

VKidz is currently owned by founder John Edelson and a fund managed by Veronis Suhler Stevenson, which owns a majority of the equity interests of VSS-Cambium Holdings III, LLC, which holds approximately 69% of the Company’s outstanding stock. Therefore, the Company’s Board of Directors formed a special committee of independent and disinterested directors to analyze and negotiate the transaction on behalf of the Company and deliver a recommendation to the Company’s Board of Directors with respect to the transaction. The Company’s special committee was advised by Needham & Company, LLC as financial advisor and Paul Hastings LLP as legal advisor.

Mr. Campbell concluded, “These are exciting times for Cambium Learning Group. We have just completed a five-year journey that changed the nature of our company from providing quality ink and paper educational solutions to one that primarily provides quality digital educational solutions. We continue to strive to serve our students and teachers with best of breed solutions as evidenced by our many awards. We have been able to assemble an excellent group of employees that propels us to be a leader in the K–12 market. All of this has culminated in giving us the opportunity to purchase VKidz and consider strategic alternatives so that we are in the best possible position to continue our long-term growth.”

Non-GAAP Financial Measures

EBITDA, Adjusted EBITDA, and Cash Income are not prepared in accordance with GAAP and may be different from similarly named, non-GAAP financial measures used by other companies. Non-GAAP financial measures should not be considered a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. The Company believes these non-GAAP measures provide useful information to investors because they reflect the underlying performance of the ongoing operations of the Company and provide investors with a view of the Company's operations from management's perspective. Adjusted EBITDA and Cash Income remove significant restructuring, non-operational, or certain non-cash items from earnings. The Company uses Adjusted EBITDA and Cash Income to monitor and evaluate the operating performance of the Company and as the basis to set and measure progress toward performance targets. Further, the Cash Income measure directly affects compensation for employees and executives. The Company generally uses these non-GAAP measures as measures of operating performance and not as measures of the Company's liquidity. The Company's presentation of EBITDA, Adjusted EBITDA, and Cash Income should not be construed as an indication that our future results will be unaffected by unusual, non-operational, or non-cash items.
