Thanks, Melissa. Good morning, everyone, and thanks for joining us today. In the fourth quarter, our teams continued to drive top-tier operating and financial performance. We want to recognize and thank all of our retail, distribution and manufacturing teams for their commitment to, and care of our customers and their communities. We are proud of the compassion, humility and passion for excellence they have shown in an exceptionally challenging environment over the last 2 years.
In Q4 '21, ID sales increased 7.5% and 19.3% on a 2-year stack. We also gained unit and dollar market share in Food and MULO on both a 1- and 2-year basis and maintained our #1 or #2 position in 68% of the 121 MSAs in which we operate. In addition, we delivered adjusted EBITDA of approximately $1.1 billion and adjusted EPS of $0.75 per share, well ahead of our expectations.
During the quarter, we continued to see a rebound in store traffic and the benefits from our digital and omnichannel investments, including the expansion of Drive Up & Go and additional micro-fulfillment centers, bringing our total MFCs to 7. Omnichannel households spent 3x more than in-store-only shoppers. And during Q4, omnichannel households grew by nearly 5x versus the fourth quarter of 2019. In addition, as our investments drove increased customer engagement and retention, Q4 '21 digital sales increased 5% year-over-year and 287% on a 2-year stacked basis.
In the Just for U Loyalty Program, benefit enhancements continued to accelerate membership growth, which increased 18% year-over-year to nearly 30 million members and is up approximately 45% or over 9 million members since the fourth quarter of 2019. Actively engaged members, defined as those redeeming coupons, fuel or grocery rewards, also continued to increase. And the redemption rate of these members remained over 90% at the end of the year. Remember that on average, actively engaged members spend 4x more than non-actively engaged customers.
I will now recap our progress against the 4 key strategic priorities that drove our better-than-expected Q4 and 2021 results. Driving in-store excellence is the foundation that enables everything we do. And our commitment to enhancing our customers' experience contributed meaningfully to the 18% year-over-year growth in our Just for U members and market share gains.
From an inventory and productivity perspective, we simplified tasks and automated production planning in our fresh departments, resulting in higher in-stock conditions and more time for customer interactions. For example, in the deli, we installed auto slicers and stackers and implemented production planning tools that increase product availability while reducing shrink and improved customer service. These changes contributed to the better-than-expected results in Fresh. During the fourth quarter, Fresh ID sales outpaced center store by 280 basis points year-over-year and over 500 basis points versus 2 years ago.
In addition, we continue to invest and modernize our store fleet, including adding and upgrading self-checkout, which is now available in over 1,800 stores, and optimizing the layout and design to improve the customer shopping experience. We completed 236 remodels and opened 10 new stores in fiscal 2021.
In Own Brands, we introduced 837 new products and increased adoption in lower-penetrated divisions, driving strong growth and improved margins. Q4 sales penetration reached 25.6% with the strongest performance in floral, deli and meat. During the year, Own Brands was awarded 4 Private Label Manufacturing Association awards, and 1 recognition from Store Brands Magazine for Innovation Private Brand Marketing.
Our next priority is the acceleration of our digital and omnichannel capabilities to fuel our growth and increase customer engagement, satisfaction and retention. In loyalty, we launched and upscale our new unified mobile app, or UMA. 87% of our digital orders were being placed in the UMA by the end of the fiscal year. We also introduced a [ meat ] planning tool that offers recipes, including those that address dietary preferences such as vegetarian or gluten-free. Customers can seamlessly add all recipe ingredients to their shopping list or immediately purchase them in the UMA.
In Drive Up & Go, we reached our goal of over 2,000 stores, serving 99% of our households. In online delivery, we expanded third-party partnerships to offer more choices and accelerate the speed of delivery. And in both Drive Up & Go and online delivery, we reduced cost per order by adding 5 additional MFCs and 3 [indiscernible] rooms. We're configuring our picking software and staffing models and improving our forecasting algorithms.
In digital, we are beginning to capitalize on our rich and proprietary data, recently launching the Albertsons Media Collective, or AMC. AMC offers [indiscernible] existing business partners for a robust digital marketing platform that reaches our extensive customer network and leverages our strong market share, especially in the 68% of markets where we hold the #1 or #2 share position. We expect AMC to be a leading growth and profit driver over the next several years.
Increasing productivity, our next priority, allowed us to continue to fund future growth and offset inflation. In the second year of our 3-year $1.5 billion savings program, we enhanced our pricing and promotion capabilities, further rationalized indirect spend and expanded our national buying initiatives. We expect to achieve our targeted $1.5 billion in savings by the end of fiscal year 2022. And we will not stop there. Later on this call, we will discuss the next phase of our perpetual productivity engine beyond fiscal year '22.
Our fourth priority is strengthening our talent and culture and supporting the communities we serve. In 2021, we continued to acquire and develop talent to transform the culture, to harness local ownership, leverage scale and support our new omnichannel imperatives. We also recognized the frontline teams for embracing this cultural transformation while delivering exceptional sales to our customers by awarding a discretionary thank you payment in the fourth quarter.
Our senior leadership team also focused on amplifying our diversity, equity and inclusion strategy. We are continuing to make progress at the senior levels of the company and are benefiting from the experience and diversity of thought that each of these leaders is bringing to the table.
In pharmacy, our teams worked tirelessly to provide COVID vaccinations for the communities we serve. To date, we have administered over 12 million vaccinations.
In ESG, we increased investment and further developed our goals in the areas of climate action; waste reduction and circularity; community stewardship; and diversity, equity and inclusion. Later this month, in conjunction with Earth Day, we will announce this comprehensive set of goals publicly.
We are very pleased with the progress we have made against all our strategic priorities, and there remains significant headroom and a strong foundation to build on in 2022. I will now turn the call over to Sharon to cover the details of our fourth quarter and fiscal year results.
