Adam Berry
Good morning, and welcome to Jabil's first quarter of fiscal 2023 earnings call. Joining me on today's call is Chairman and Chief Executive Officer, Mark Mondello; and Chief Financial Officer, Mike Dastoor.
Please note that today's call is being webcast live, and during our prepared remarks, we will be referencing slides. To follow along with the slides, please visit jabil.com within our Investor Relations section. At the conclusion of today's call, the entirety will be posted for audio playback on our website.
I'd now like to ask that you follow our earnings presentation with slides on the website, beginning with the forward-looking statement. During this conference call, we will be making forward-looking statements, including, among other things, those regarding the anticipated outlook for our business, such as our currently expected second quarter and fiscal year net revenue and earnings. These statements are based on current expectations, forecasts and assumptions involving risks and uncertainties that could cause actual outcomes and results to differ materially. An extensive list of these risks and uncertainties are identified on our annual report on Form 10-K for the fiscal year ended August 31, 2022, and other filings. Jabil disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.
With that, I'd now like to shift our focus to our solid quarter. To kick off the fiscal year, the team delivered approximately $9.6 billion in revenue, well ahead of our forecast and at the top end of our guidance range, driven by even better-than-expected revenue in automotive, healthcare and industrial. All other end markets largely performed consistent to our expectations from 90 days ago.
When you put all of this together, at the enterprise level, revenue grew by 12% year-over-year and 7% sequentially. Core operating income during the quarter was $461 million, an increase of 15% year-over-year, representing a core operating margin of 4.8%. This is up 10 basis points over the prior year and in line with expectations. From a GAAP perspective, operating income was $362 million, and our GAAP diluted earnings per share was $1.61.
