Corinthian Colleges Reports

FY 14 First Quarter Results

SANTA ANA, Calif., November 5, 2013 (GLOBE NEWSWIRE) — Corinthian Colleges, Inc. (NASDAQ:COCO) reported financial results today for the first quarter ended September 30, 2013. The results for the quarter were within the Company’s previous guidance range for diluted earnings per share, and fell below guidance for new student enrollment and revenue. (Guidance is for continuing operations only and excludes all one-time charges. In the first quarter the Company recorded a $3.7 million impairment, facility closing and severance charge, and put four schools up for sale.)

“During the first quarter we continued to focus on student outcomes and initiatives to increase our student population and improve operational efficiency,” said Jack Massimino, Corinthian’s chairman and chief executive officer. “In addition, we made further expense reductions to help offset the impact of a lower student population.”

“As expected, total new student enrollments declined quarter-over-quarter, the result of a decline in new online students,” Massimino said. “To help increase our online student population, we recently implemented new workforce management technology for the service centers and improved the alignment of staffing and call volume.  In addition, we are in the process of implementing a new academic model to create greater student engagement and retention. We believe these and other initiatives will help position Online for improved performance over time.”

“Our ground school new enrollments were up slightly quarter-over-quarter,” Massimino said. “Our growth initiatives for the ground schools include introducing new promotional programs in certain service areas, implementing new programs, and offering free GED programs at most Everest campuses. In addition, we continue to see higher new student enrollments in service areas where competitor school closures have occurred.”

“In the second quarter, we expect a decline in new enrollments, owing to Online’s on-going operational initiatives and regulatory delays in approving new ground school programs,” Massimino said. “In addition, we are transitioning to an in-house system for certain lead-management functions, which has temporarily reduced the quality and speed of prospective student inquiries delivered to our schools and online service centers. When fully implemented, we believe the new system will be more efficient and effective than the outside vendor used previously.”

Comparing the first quarter of fiscal 2014 with the same quarter of the prior year: (Note: results are for continuing operations only, and exclude impairment, facility closing and severance charges unless otherwise stated.)

Financial Review —

Impairment, facility closing and severance charges - During Q1 14 we recorded a charge of $3.7 million versus a similar charge of $0.8 million in Q1 13. The charge was primarily related to severance expenses associated with workforce reductions.

Educational services expenses were 62.2% of revenue in Q1 14 versus 60.5% in Q1 13.  The increase was primarily due to a decrease in total student population (and revenue) relative to fixed costs. Bad debt was 4.9% of revenue in Q1 14 versus 4.8% of revenue in Q1 13.

Marketing and admissions expenses were 27.7% of revenue in Q1 14 versus 24.3% in Q1 13.  The increase is primarily the result of duplicative costs associated with bringing certain lead management services in-house and lower conversion rates.

General and administrative expenses were 11.6% of revenue in Q1 14 versus 10.7% in Q1 13.   The increase was primarily due to a decrease in total student population (and revenue) relative to fixed costs.

The operating margin was (1.6%) in Q1 14 versus 4.5% in Q1 13, excluding facility closing and severance charges in both time periods.

Cash and cash equivalents totaled $37.2 million at September 30, 2013, compared with $46.6 million at June 30, 2013.  The decrease in cash is primarily due to the timing of cash receipts and payments.

Debt and capital leases (including current portion) totaled $101.1 million at September 30, 2013, compared with $139.1 million at June 30, 2013.

Cash flow from operations was $41.0 million in the first quarter ended September 30, 2013, versus $20.4 million in the first quarter last year. The increase is primarily due to the timing of cash receipts and payments.

Capital expenditures were $12.9 million in the first quarter ended September 30, 2013.

Regulatory Update

California Attorney General Complaint — As previously disclosed in a Report on Form 8-K, on October 10, 2013 the California Attorney General (CAG) filed a civil complaint against the company. We have been cooperating with CAG’s investigation since it began in December 2012. We were disappointed that we were not given advance notice of the complaint, and did not have the opportunity to discuss the allegations with CAG before the complaint was filed.

The complaint contains allegations that paint a misleading and inaccurate picture of our company and schools. We are fully committed to providing quality career and technical education; to making every effort to help graduates find employment in their chosen fields; and to ensuring that students are treated fairly and honestly. Further, we have robust regulatory compliance systems in place. We plan to vigorously defend against this lawsuit, and look forward to making our case in court.

Guidance

The following guidance is for continuing operations and excludes any one-time charges.
