Good morning, welcome to Shake Shack's 2023 Annual Meeting of Shareholders. At this time, I would like to turn the conference over to Randy Garutti, Shake Shack's Chief Executive Officer and a member of the company's Board of Directors. Please go ahead, sir.
Thanks, operator. Good morning, everyone. We really appreciate your interest in Shake Shack and taking time to join us today. I'd like to start, as I always do, by thanking our team for their commitment and dedication this past year and thanking our shareholders for your continued support. We entered 2022 with a clear strategy to build back our profitability, recover sales, and accelerate our growth and development. Despite inflationary pressures across nearly every input item, supply chain constraints, a tight labor market, and widespread construction delays, 2022 was a year of significant progress for Shake Shack. We executed against our strategic plan, opening our 436th Shack and delivering record-level System-wide sales.
We finished the 4th quarter with solid financial performance, with year-over-year high teens revenue growth, 240 basis points expansion in Shack-level operating profit margin to nearly 19% and over 55% growth in Adjusted EBITDA. This year, as we continue to steadily improve results, we remain focused on the important details of the consistent and reliable day-to-day execution that will deliver higher performance for years to come. We are pleased with our progress against our strategic plan, which includes recruiting, rewarding, and retaining a winning team, focusing on the guest experience, building a targeted development strategy, improving Shack margins, and investing with discipline for strong returns. Our work is far from over, and we believe we're on the right path with the right team to maximize total long-term growth and profitability potential.
Our purpose remains to stand for something good. We're excited to share our 2022 Stand For Something Good summary, which is now available on our website, where we share our commitment to social impact, environmental responsibility, and governance. We engaged stakeholders, collected impact data, highlighted suppliers, focused on quality ingredients, and identified areas for progress in the future. As we continue to grow as the Shake Shack of tomorrow, we're committed to learning, measuring, improving, and sharing what we're up to. We're humbled by the actions of the entire Shake Shack family, who've led with hard work and commitment while doing what we love. I'll now turn the meeting over to Ron Palmese, our Chief Legal Officer, to conduct the formal business of the meeting.
Thank you, Randy. We are pleased to once again be holding our annual meeting virtually, which we believe provides our shareholders the best opportunity to attend our annual meeting. I'm joined by Randy, as well as our director nominees, our other directors, and a representative from our registered accounting firm, Ernst & Young. Today's session allows our shareholders to participate in the meeting, regardless of their location. Not only can you view the meeting, you may also submit questions and vote your shares online before the polls close. We've allocated time after the adjournment of the formal part of the meeting for Q&A. There's a text box on your screen where you can submit your questions anytime throughout the meeting. If we're unable to get to your questions, you may always email us at investor@shakeshack.com.
Before we begin our prepared remarks, it is possible that some of this morning's comments or responses to your questions may contain forward-looking statements that are based on certain assumptions and that are subject to known and unknown risks, uncertainties, and other important factors that may cause actual results to be materially different, including those set forth in our risk factors in our annual report on Form 10-K and other reports filed with the SEC. We have three items of business to conduct in today's meeting. They are to reelect four of our directors as Class II directors, to consider and act upon a proposal to ratify the appointment of our auditors as our independent registered public accounting firm for the current fiscal year ending December 27, 2023, and to conduct an advisory vote on the compensation of Shake Shack's named executive officers.
Momentarily, I will announce the opening of the polls as we call for a vote on the matters to be presented for your consideration at this meeting. After the votes are tallied and announced, we will adjourn the formal part of our meeting. The board of directors has appointed Peter Descovich of Broadridge to serve as our Inspector of Election. He is present at the meeting today, and as required by law, Mr. Descovich has taken and signed an oath as Inspector of Election. A certified list of the shareholders of record entitled to vote at today's meeting for purposes of sending the notice of meeting and proxy statement is available online, and I have an affidavit from Broadridge attesting to the delivery of the notice.
Mr. Descovich has advised me that the majority of the company's outstanding voting shares held of record as of the close of business on May 8, 2023, the record date for this meeting, are represented at today's meeting in person or by proxy. I declare that a quorum is present and that we may proceed with the business of the meeting. Please remember that you may vote your shares online anytime during the meeting, prior to the closing of the polls. We will now proceed to the voting on the items I described. It's approximately 9:05 A.M. Eastern Time. The polls are now open for voting on each of the items of business. If you have previously voted by proxy and do not wish to change your vote, your vote will be cast as you previously instructed, and no further action is needed.
If you are a record holder and wish to change your vote, did not send in a proxy and wish to cast your vote now, or have not already cast your vote using our electronic voting system, you may cast your vote by electronic ballot at virtualshareholdermeeting.com/SHAK2023 at this or any time until the conclusion of the meeting. You will notice a link to the voting site on your screen. Access to virtualshareholdermeeting.com/SHAK2023 requires the control number you received prior to the meeting. As mentioned, the first order of business is the election of four directors. The following persons are nominated as directors: Randy Garutti, Joshua Silverman, Jonathan Sokoloff, and Tristian Walker . The second item is the proposal to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 27th, 2023.
The third item is to conduct the advisory vote on the compensation of the company's named executive officers. We will be closing the polls momentarily. You must submit your electronic ballot in order for your votes to be counted. The Inspector of Election will not accept votes submitted after the closing of the polls. Please note that any votes by electronic ballot submitted today will be subject to final verification by the Inspector of Election. There being no further ballots, I hereby declare that the polls are now closed at 9:06 A.M. Eastern Time for voting on the items of business. All electronic ballots and proxies are now in the custody of the Inspector of Election. We have received the preliminary tabulation of votes by our Inspector of Election. All votes are subject to final count, certified by the inspector.
Based on the preliminary report, each of the persons nominated as a director received a majority of the votes cast and is hereby elected as a Class II director of the company. The resolution relating to the ratification of the appointment of Ernst & Young as independent registered public accounting firm for the fiscal year ending December 27th, 2023, received the majority of votes entitled to vote at the meeting and present in person or by proxy, and E&Y is hereby approved as our accounting firm. The proposal to approve on an advisory basis the compensation of the company's named executive officers, received the majority of the votes entitled to vote at the meeting and present in person or by proxy, and hereby passed. Based on the vote, I declare that the proposals have been approved.
It's now 9:07 A.M. Eastern Time. I declare the formal business of today's meeting is concluded. The company will report the final voting results on a Form 8-K filed with the SEC within 4 days of today's meeting. I would now like to open the meeting up to questions. I'll read the questions out loud. Our first question is: Is there any consideration for us adding an official fish sandwich as a standard menu option?
I'll take that. This is Randy. Thanks, Joseph, for asking the question. You sound like a true Shack fan. We appreciate it. You know, we've done a few things over the years. Even last week, we did a fun fish sandwich collaboration in Mexico with a famous restaurant. As far as our core menu here in the United States, we don't have any plans at this time. We launched a great new veggie burger this year. I hope you'll give that a shot and continue to work on our core products to keep the operations streamlined and delighting our guests with fun, limited time offers in our core menu. Thanks again, and just know we're always cooking up some fun ideas in the innovation kitchen.
As there are no further questions, I'd like to thank you again for your continued support of Shake Shack. The meeting is now closed. Have a great day.
Thank you. This concludes today's meeting. You may now disconnect your lines.
