Thank you, Kevin, and good morning, everyone. As a reminder, I'll be referring to adjusted results today. Please turn to slide three in our presentation for a review of our fourth quarter performance. Most of our businesses performed in line with our expectations during the fourth quarter, with the exception of an isolated situation in our Broadcast Solutions segment. We had expected to recognize revenue on $36 million of product that was shipped in 2017, but we were unable to do so as a result of technical US GAAP revenue recognition requirements that our team identified during the year-end closing process.
We now expect these 2017 shipments to be recognized as $36 million in revenue and $22 million in EBITDA in 2018, and this will be additive to the revenue and EBITDA that we otherwise would have anticipated. As a result, revenues in the fourth quarter decreased 50 basis points to $604.9 million. Our Enterprise, Industrial, and Network Solutions segments performed in line with our expectations, growing 8% on a combined basis from the prior year period.
EBITDA in the fourth quarter was $110.2 million, or 18.2% of revenue. Our proven Lean enterprise system continues to drive sustainable productivity gains, with year-over-year EBITDA margin expansion in our Enterprise, Industrial and Network Solutions segments. EPS increased 14.1% in the fourth quarter, from $1.42 in the prior year period to $1.62.
Looking to 2018, we raised our full-year revenue guidance range by $36 million to reflect the 2017 shipments that will now be recognized as revenue in 2018. We expect improved organic growth in 2018. And we're encouraged by the
