C. Howard Nye
Chairman, President and Chief Executive Officer at Martin Marietta Materials
Thank you, Suzanne. And thank you all for joining today's teleconference. We are excited about Martin Marietta's opportunities for operational, safety and financial success in 2022 and beyond. We're off to a predictable start this year. And our company's prospects for attractive growth and value creation are outstanding. Public and private construction activity are set to expand concurrently for the first time since this industry's most recent shipment peak in 2005, supporting multi-year demand and pricing acceleration for our products.
Beyond the benefits of these notable industry dynamics and underlying market fundamentals. We're confident that continued disciplined execution of our strategic operating analysis and review or SOAR. Will allow for responsible and sustainable growth of our coast-to-coast footprint. As highlighted in today's release, we once again exceeded world-class safety metrics company-wide. That's an important distinction as this performance includes operations that are relatively new to Martin Marietta guardian angel culture.
We also achieved a new first-quarter record for consolidated total revenues, which increased 25% pricing gains ahead of more broadly planned April increases. Organic upstream shipment growth in 2021 acquisitions all helped drive this top-line improvement. Cost inflation, however, outpaced revenue growth, resulting in reduced first-quarter profitability and margins versus the prior-year quarter. This was expected. In fact, our guidance provided in February weighted increased profit contributions to the second half of 2022 versus historical patterns. The reasons we anticipated and articulated regarding the shift we're two-fold.
First, our annual price increases, which are some of the largest and Martin Marietta's recent history mostly become effective on April 1st, the benefit from which builds throughout the year. Second, our costs, including energy headwinds, were anticipated to be more pronounced earlier in the year since comparable periods in the previous year experienced relatively benign inflation. What was unexpected though, was the rapid escalation and energy prices and other cost inflation in recent months. Nonetheless, beyond achieved and yet to be realized annual price increases, we're confident that disciplined execution of our commercial and operational excellence initiatives will more than offset these inflationary headlines.
It's important to remember that historically, inflation supports a constructive pricing environment for upstream materials, the benefits of which endure long after inflationary pressures moderate. Our teams are actively advising customers of mid-year pricing actions, which we anticipate will be widely accepted and more aggressive in scope and magnitude than we were initially considering a few months ago. Longer-term, Martin Marietta is well-positioned to execute on our value over volume pricing strategy and benefit from what is expected to be an increasingly more favorable and extended pricing cycle.
Confidence in our near- and long-term outlook is further underpinned by the disciplined execution of our SOAR 2025 priorities. During the quarter, we continue to optimize and enhance our aggregate SLED portfolio. We completed the divestiture of our Colorado and Central Texas ready-mix concrete businesses to the nation's largest privately-owned concrete producer on April 1. We also recently entered into an agreement to sell our Redding cement plant, related cement distribution terminals, and 14 ready-mix concrete plants in California to CalPortland Company. We expect to complete this transaction in the second half of 2022.
Collectively, these portfolio optimization actions both strengthened the durability of our business through economic cycles and enhance our margin profile. We intend to deploy the proceeds from these sales to advance our long-standing capital allocation priorities, facilitating higher-return, external, and organic growth investments to further enhance shareholder value. Before discussing our updated for your guidance, let's level set first-quarter results relative to the rest of 2022. While profits were lower than last year's for the reasons just discussed, the key takeaway is that the first quarter does not represent the beginning of a price cost margin compression trend.
Rather, we believe it's the end of the margin compression dynamic for the company, the scale, frequency, and efficacy of our price increases provide us the confidence to forecast full-year margins for 2022 exceeding those of 2021. In short, we believe better than expected aggregates pricing realization and contributions from our newly acquired West Coast operations will offset the divested earnings and expected inflationary headwinds.
As a result, we've reiterated our full-year adjusted EBITDA midpoint guidance of $1.75 billion. As pricing momentum continues to build during the spring construction season, we anticipate that further pricing upside is probable. Accordingly, we'll revisit our full-year guidance after the second quarter. Turning now to first-quarter operating performance for our upstream and downstream businesses, organic aggregate shipments increased to 2.5%, reflecting growing public and private demand at the onset of the construction season.
Encouragingly, Infrastructure shipments increased 6%, the largest percentage increase we've seen in several years. Acquired operations contributed an additional 4 million tons. Underpinned by our value over volume strategy, organic aggregates pricing increased 6.5% or 4.6% on a mix adjusted basis and reflected improving long haul shipments from higher-priced distribution yards. All divisions contributed to this pricing growth. As the largest cement producer in Texas, we continue to benefit from tight supply and robust product demand.
Shipments exceeded 1 million tons and increased 10% setting a new first-quarter record. Cement pricing grew 12% from multiple actions taken in 2021 and the resurgence and demand for higher-priced specialty products. With a $12 per ton increase effective April 1 and our recently announced second round increase of an additional $12 per ton effective July 1, the Texas cement pricing outlook is extremely attractive. Organic ready-mix concrete shipments remained relatively flat despite the completion of several large and typically higher priced, portable projects.
Organic concrete pricing grew 8% following off cycle price increases and the implementation of fuel surcharges. Organic asphalt shipments decreased 3% as significant snowfall in January and February hindered Colorado construction activity. Organic asphalt pricing improved 6%. Looking beyond the first quarter, we remain confident that attractive market fundamentals and strong demand across our three primary end-use markets will drive aggregates-intensive growth and favorable pricing trends for Martin Marietta for the foreseeable future.
Enhanced infrastructure investments should drive aggregate shipments to this end-use closer to our 10-year historical average of 40% of total shipments. For reference aggregates to the infrastructure market accounted for 32% of first-quarter organic shipments. Department of Transportation budgets for our top states continue to be well funded through traditional revenue sources, as well as $10 billion dollars of COVID relief aid pushing estimated lettings nicely above prior levels.
Increased funding from the Infrastructure, Investment and Jobs Act or IIJA, will further enhance the current strength of our state DOT programs, providing DOTs with increased visibility and certainty to advance their multitude of backlog projects. With full IIJA allocation available for 2023 DOT fiscal years, the majority of which began on July 1, we expect benefits to begin accruing in late 2022 and become more pronounced in 2023. Non-residential construction, which drove 36% of Martin Marietta first-quarter aggregate shipments continues to benefit from the paradigm shift in consumer and work preferences and supply chains as evidenced by increased investment in aggregates intensive warehouses, data centers, and reassuring of manufacturing facilities to the United States.
Commercial and retail construction throughout our Sunbelt markets is expected to become more significant demand driver in 2022 as it's typically follows, single-family residential development with a nine-to-12-month lag. By way of example, Charlotte, North Carolina. On an office trends are returning to pre -pandemic levels with more than 2.6 million square feet of office space currently under construction in that area. The residential construction outlook remains strong despite rising interest rates and inflationary pressures, following more than a decade of historically bold new housing construction.
Expectations are that annual single-family housing starts remain in line with early 2000 levels over the next few years. That said the United States has added over 30 million people in the intervening period. Given our company's attractive footprint in destination metropolitan areas, we expect Martin Marietta to benefit disproportionately from new home construction for the foreseeable future.
As a reminder, construction of single-family homes in subdivisions is nearly three times more aggregates intensive than multi-family construction. Given further, community build out of light non-residential and infrastructure. Aggregates to the residential market accounted for 26% of our first-quarter organic shipments.
I'll now turn the call over to Jim to discuss more specifically, our first-quarter financial results and liquidity, Jim.
