Linamar Corporation, the Canadian auto parts giant, just posted another stellar quarter. Record sales, double-digit growth, margin expansion – it's a success story for the ages. But delve a little deeper into the numbers, specifically into the triumphant return of the Mobility segment, and a shadow begins to emerge – the silent, but significant, impact of the Mexican peso.

The official narrative is clear: Linamar’s Mobility segment, after facing headwinds for several quarters, is back on track. Q4 2023 saw both earnings and margins growing again, and the projections for 2024 are nothing short of spectacular, with double-digit operating earnings growth and a projected return to the normal 7%-10% margin range within a couple of years.

But within this narrative of success, Linda Hasenfratz, Linamar’s CEO, drops a telling clue. Both Q3 and Q4 margins, she admits, were "well understated based on the currency impact in comparison to prior year." The culprit? The volatile Mexican peso, which saw a significant appreciation against both the Canadian and US dollars.

The impact of the peso's appreciation is far from trivial. While Q4 Mobility earnings saw a solid 7% growth over the prior year, a constant currency analysis reveals a hidden truth: growth would have reached double digits, and margins would have actually exceeded those of the prior year.

This begs the question: is the Mobility segment’s recovery truly as robust as it appears? Or is it propped up, at least partially, by a favorable currency environment?

To answer this, let’s consider a hypothesis. Let’s assume that the peso's appreciation provided a 3% artificial boost to both earnings growth and margin in Q4. If we remove this boost, the 7% earnings growth dwindles to a more modest 4%, and the reported margin, just shy of 5%, drops to approximately 2%.

This adjusted picture is far less impressive, painting a recovery that is more gradual than meteoric. While the underlying business is undoubtedly improving, the peso's appreciation is masking the true pace of that recovery.

This is not to diminish Linamar's achievements. Their diversification strategy, their innovative products, their ability to navigate volatile markets – all deserve commendation. But investors should be aware of the peso’s influence. A continued appreciation of the peso will bolster the Mobility segment’s apparent recovery, while a depreciation could expose underlying weakness.

Moving forward, Linamar needs to demonstrate that the Mobility segment can achieve sustainable, organic growth independent of currency fluctuations. They need to convince investors that the peso is a tailwind, not a crutch.

Hypothetical Impact of Peso Appreciation on Linamar's Mobility Segment Q4 Results

"Fun Fact: Linamar was founded in 1964 by Frank Hasenfratz, a Hungarian immigrant to Canada who started the business in his basement. His entrepreneurial spirit and drive for innovation are deeply embedded in the company's DNA. Today, Linamar is a global force in the auto parts industry, with over 26,000 employees worldwide."

Linamar's journey, from basement startup to global giant, is a testament to their resilience and adaptability. But as they navigate the turbulent waters of the automotive industry's transformation, they must remain vigilant. The peso's silent influence is a reminder that even the most impressive numbers can harbor hidden truths.
