Hidden within the seemingly mundane details of Arcosa's Q1 2024 earnings call transcript lies a potentially explosive insight, overlooked by the usual Wall Street chorus. CEO Antonio Carrillo, in a series of seemingly offhand remarks, reveals a quiet shift in the barge market that could signal a resurgence in liquid shipping, a sector long languishing in the doldrums. This could mean a substantial boost for Arcosa's Transportation Products segment, sending ripples through the broader inland shipping industry.

Carrillo's bullishness stems from a recent uptick in tank barge orders, a trend Arcosa has witnessed over the past two quarters. While these orders aren't massive, they mark a significant departure from the anemic demand of the past few years. Carrillo, however, goes beyond just acknowledging this shift. He paints a picture of a burgeoning liquid shipping revival, driven by aging fleets and a looming maintenance crisis.

""The tone we're seeing from our customers, which a year ago were saying, 'Well, I don't need anything,' all of them are coming and saying, 'Look, we see all this replacement coming in the near future, and there's not going to be enough capacity to supply the replacement of tank barges,'" Carrillo declared, capturing the change in customer sentiment."

This shift, he argues, is fueled by a confluence of factors. First, years of underinvestment have left the liquid barge fleet aged and in desperate need of replacement. Second, impending regulatory deadlines for recertifying barges are exacerbating the existing barge shortage, pushing operators to secure new vessels sooner rather than later.

Carrillo's confidence is palpable as he describes Arcosa's strategic realignment to capitalize on this emerging trend. The company, traditionally focused on producing dry cargo hopper barges in recent years, is shifting gears, retooling one of its plants to specialize in tank barge production.

""We will be realigning the production mix in our plants, so they can focus on producing barges that maximize efficiency and margins," Carrillo explained, emphasizing the importance of this strategic maneuver."

While this realignment will cause a slight margin dip in Q2 2024 as production shifts, Carrillo anticipates a significant margin boost once the transition is complete. This strategic maneuvering suggests that Carrillo isn't just reacting to a short-term blip in demand. He's betting big on a sustained, long-term resurgence in liquid shipping.

Barge Backlog Growth

The following chart illustrates the growth in Arcosa's barge backlog, suggesting increasing demand.

So, what are the potential numbers behind this whisper of a liquid shipping boom? Arcosa's Q4 2023 barge backlog stood at $254 million, a 13% year-over-year increase. With the 2024 production capacity substantially booked and the company actively seeking orders for 2025, the potential for significant revenue growth is clear. Considering that barge revenue nearly doubled in Q4 2023 compared to the prior year, a 20% or higher revenue growth in 2024, driven by a tank barge resurgence, isn't an unreasonable projection.

Furthermore, Arcosa's focus on margin expansion within the barge business, as evidenced by the disciplined bidding strategy and the plant realignment, suggests a potential for significant EBITDA growth within the Transportation Products segment. While the Q1 2024 margin will be impacted by production shifts, a subsequent margin boost, coupled with higher volumes, could propel the segment's EBITDA growth to levels significantly higher than the 16% growth forecast for the overall company.

The potential implications of this shift extend beyond Arcosa's balance sheet. A resurgence in liquid shipping, particularly if constrained by production capacity, could create a ripple effect through the entire inland shipping industry, leading to higher barge prices, increased demand for skilled labor, and a renewed focus on modernizing aging fleets.

Carrillo, with his finger on the pulse of the barge market, appears to be a step ahead of most analysts. His bullishness on tank barge demand, backed by strategic realignment and a clear focus on margin expansion, suggests that a liquid shipping boom may be on the horizon, a development that could significantly alter the dynamics of the inland shipping industry.

"Fun Fact: The Mississippi River system, a key artery for inland barge transportation, handles over 500 million tons of cargo annually, including agricultural products, petroleum, and coal. A resurgence in liquid shipping could lead to increased traffic on this vital waterway."
