Thanks, Melissa. Good morning, everyone, and thanks for joining us today. We entered uncharted territory in Q1 with comparisons to last year's pandemic stock up period and the gradual reopening of various geographies as vaccination rates accelerated and COVID-related restrictions were lifted. In this dynamic environment, we remain focused on executing our strategy centered around deepening relationships with our customers and leveraging technology to run our business more efficiently and effectively. I am pleased to report that our results for the quarter exceeded our internal plans across all key metrics, increasing our confidence in the balance of this year.
Our ID sales grew 16.5% on a 2-year basis, and we continue to gain market share in food on a 1-year basis and in MULO, which includes most food, drug, mass, club, dollar and military on a 2-year basis. In addition, we achieved EBITDA of -- adjusted EBITDA of $1.3 billion and adjusted EPS of $0.89 a share ahead of our expectations.
Against the backdrop of growth exceeding 200% in every quarter in fiscal '20, our digital initiatives continue to resonate with our customers. And we have retained the sales levels we achieved last year with digital sales virtually flat year-over-year in Q1, and a 2-year stacked ID sales growth of 276%. With all the options we have in place, we have achieved 95% customer coverage with eCommerce and retention has been strong. At the same time, we have seen a pickup in in-store transactions versus Q1 '20, and many of those incremental in-store shopping trips are focused on fresh.
At the end of Q1 '21, we had 3.6x the number of omnichannel households than we had 2 years ago in '19. We've seen that as customers move into omnichannel, they also increased their spend in our stores with a net growth of 17% per household spend in the quarter and a total spend rate of 2x that of an exclusively in-store shopper. In fact, in Q1, with identified households, an average in-store-only shopper sales were down while the omnichannel customer sales were up year-over-year. We've grown our identified households by 8% year-over-year for the last 52 weeks, allowing us to better understand their needs so we can personalize our offerings for them and drive recurring and incremental spend.
Membership in our just for U loyalty program continued to accelerate and was up over 18% year-over-year in Q1 '21 to 26.7 million members. We also increased the number of actively engaged customers by almost 13%, and we have a 94% retention rate that engage just for U households. Remember that actively engaged customers spend 4x more with us.
In summary, our strategy of building lasting relationships with customers through a combination of digital and in-store engagement is driving our top line. Overall, our strategy is focused on 4 priorities: in-store excellence, accelerating our digital and omnichannel capabilities, driving productivity and strengthening our talent and culture. In-store excellence is demonstrated through the one-stop shopping experience we continue to provide for our customers supported by the quality, variety and depth of our fresh and Own Brands offerings that give us a competitive advantage. In fresh, which has always been a strategic focus for us, we continue to see stickiness giving us confidence that our strategy is working. The fresh department sales growth outpaced center store by approximately 200 basis points on a 2-year basis, which each of our fresh categories ahead of pre-pandemic levels as customers continue to consume more meals at home. As our markets have opened up, we've seen customers shopping in our stores more often and continue to see fresh as a key driver for growth.
Our Own Brands portfolio also continues to appeal to our customers with strong sales driven by the introduction of new innovative products as well as our focus on Albertsons legacy divisions that were historically underpenetrated. Our Q1 sales penetration was 25.2%, up over 100 basis points from Q1 '20 when supply issues impacted sales. We continue to innovate launching 318 new items in Q1 '21, many of which were Signature farms bulk items, including trail mixes, various nuts and dried fruits, Open Nature almond butter and Signature select premium beef patties. We continue to expect to launch over 800 items this year. We're also proud of our Own Brands team that was named the Store Brand Magazine 2021 Game Changer as a private brand that revitalized the industry.
We also continue to capitalize on demand for convenient and fresh meals as consumers come to us for food beyond the purchase of ingredients. We have begun the rollout of our ready meals, our ready-to-eat, ready-to-heat and ready-to-cook meals program and expect to be in approximately 500 stores by our fiscal year-end. Finally, we continue to invest in our stores. We opened 5 new stores and completed 33 upgraded and remodel projects during Q1 '21.
Our second priority is the acceleration of our digital and omnichannel capabilities. Digital is an important growth driver for us as we strive to provide an area of convenient shopping experiences for our customers. We added a net 320 new DUG locations, Drive Up & Go locations, in Q1 '21, bringing our total to 1,740. And DUG sales grew 75% year-over-year. We now expect to have DUG in approximately 1,950 locations, representing approximately 98% coverage by the end of the second quarter.
As part of our growth plans in digital, we also remain focused on delivering a superior customer experience as well as improving profitability. For example, we continue to achieve on-time tilling and delivery rates in excess of 95%, demonstrating consistent on-time delivery and DUG pickups. We began the rollout of our integrated loyalty and eCommerce app offerings of connected customer experience through a single interface.
We launched a new San Jose [ Bay Area ] MFC, and that plans for an additional 6 MFCs before the end of our fiscal year, bringing the total to 9 MFCs. We sped up delivery times while reducing delivery cost per order by expanding our third-party delivery store network while also adding DoorDash 1-hour delivery to our eCommerce options, which has been rolled out to 9 divisions so far. We also implemented our enhanced picking software at all DUG locations to help optimize and standardize picking processes, increasing picks per hour and enhancing order prioritization. And we improved customer service by migrating all support to one IT platform.
Our third strategic priority is driving productivity to support reinvestment in the business and help offset inflation. We are making progress against our productivity agenda, and we exceeded our internal expectations in Q1. During the quarter, we made significant progress in labor efficiency, shrink, promotions optimization and indirect expense. We continue to expect to achieve $1.5 billion in gross savings by the end of fiscal '22.
Our fourth priority is strengthening our talent and culture and supporting the communities we serve. We continue to add talent throughout the company at both the corporate and division level, including the recent appointment of Jennifer Saenz, our new Chief Merchandising Officer, and are very proud of our store-level teams who are adapting well to a changing environment. Our pharmacy team also continues to come through for our communities. To date, they have administered 6 million COVID vaccine doses. In addition, during Q1, our Nourishing Neighbors fundraising drive raised approximately $9 million from our generous customers at our check stands, which was matched by the Albertsons Companies Foundation resulting in $18 million in funds to feed children and families this summer.
As part of our ongoing focus on ESG, we recently announced that we are the first company in America to introduce a 100% zero-emission refrigerated grocery delivery truck. And we have been enhancing our supplier diversity program through new partnerships and an improved database and tracking tool. And in conjunction with our recently completed new materiality assessment, we're focused on quantifying our carbon reduction opportunities, baselining our food waste, plastic and packaging footprints and further developing goals and targets for DE&I and community stewardship. We expect to share our key focus areas and commitments later this year.
And now I would like to ask Bob to cover the details of our first quarter financial results and outlook.
