Nearshoring Mexico: What 201 SEC Filings Reveal

Nearshoring Mexico appears in 201 operational SEC filings from over 30 companies across 15 industries — but the most important finding is hiding inside two 10-K filings from the same SIC code. Teleflex, a surgical instruments maker, invested $36.4 million in Mexico PP&E last year while disclosing that its Mexico-manufactured products are "not currently compliant" with the USMCA. Standard Motor Products, an auto-parts manufacturer, explicitly states that its Mexico operations are "currently mostly exempt from tariffs under the United States-Mexico-Canada Agreement." Both companies are expanding Mexico manufacturing. Only one is protected from the tariffs that make that expansion worthwhile.

This compliance divide — invisible from reading any single filing — is the defining fault line in Mexico nearshoring. The advantage isn't being in Mexico. It's qualifying under the trade agreement that makes Mexico economically distinct from China. Companies on the wrong side of that line are investing millions in a manufacturing base that currently offers no tariff benefit over producing in Shenzhen.

The Tariff Shelter: Standard Motor Products

Standard Motor Products is the clearest USMCA success story in the filing data. The company doesn't hedge — its 10-K states the competitive advantage directly.

"Our significant manufacturing operations in North America produce products that are currently mostly exempt from tariffs under the United States-Mexico-Canada Agreement."

That single sentence turns Mexico from a tariff liability into a tariff shield. SMP's Mexico long-lived assets grew 28% year-over-year to $27.1 million, and the company employs approximately 5,700 people with significant manufacturing operations in Mexico. But the asset growth is secondary to the compliance status: SMP can import Mexico-manufactured products to U.S. customers at tariff rates that competitors sourcing from China, or even from non-compliant Mexico operations, cannot match.

The filing doesn't stop at the good news. SMP acknowledges tariff exposure from its broader supply chain — it also imports from Canada, China, and the European Union. The USMCA exemption protects the Mexico leg of that chain, not all of it. But for the core manufacturing base, the compliance status is an explicit, disclosed competitive moat.

Standard Motor Products' $27.1 million Mexico asset base, growing at 28% annually under full USMCA tariff protection, represents the template for how nearshoring was supposed to work — a cost-effective production base with trade-agreement insulation from the tariff volatility hitting non-compliant competitors.

The Compliance Gap: Teleflex and Stoneridge

Teleflex presents the opposite case from SMP — and it's far more common across the 201 filings. TFX has four major manufacturing locations: Czech Republic, Malaysia, Mexico, and the United States. Mexico PP&E surged 36% in a single year, from $100.0 million to $136.4 million, making it the company's second-largest asset base at 27% of total PP&E — nearly matching the U.S. at $151.0 million. Teleflex has roughly 15,500 employees, with its global supply chain workforce concentrated primarily in Mexico, Malaysia, the U.S., and the Czech Republic.

Then comes the disclosure that reframes the entire investment.

"Tariffs and accompanying retaliatory measures adversely impacted results, primarily due to higher import costs associated with our operations in the European Union, as well as to products manufactured in Mexico that are not currently compliant with the United States-Mexico-Canada Agreement (USMCA)."

Teleflex is running a $136 million Mexico manufacturing operation that doesn't qualify for USMCA tariff exemptions. At prevailing tariff rates, the cost differential between USMCA-compliant and non-compliant Mexico production is material — TFX's MD&A confirms that tariffs "adversely impacted results." The company is effectively betting that it can achieve USMCA compliance before tariff policy makes its Mexico investment uneconomic. That bet is not disclosed as a strategic initiative — it emerges only from reading the footnote segment data (where the $36 million PP&E increase appears) alongside the MD&A tariff disclosure.

Stoneridge tells a similar story with an even more dramatic asset shift. SRI spent $6.4 million on restructuring its Juarez, Mexico facility for "operational efficiency initiatives" that the company expects will deliver labor cost savings. Despite the restructuring expense, Mexico long-term assets grew 67% year-over-year — from $5.3 million to $8.8 million — while U.S. assets collapsed 70%, from $90.1 million to $26.6 million. Mexico revenue reached $40.2 million.

"Realignment expenses of $6.4 million and $2.6 million were incurred during the years ended December 31, 2025 and 2024, respectively. Realignment expense for 2025 was related to operational efficiency initiatives at our Juarez facility, which we expect will result in cost savings for direct and indirect labor and a more efficient overall operating structure."

Critically, Stoneridge's filing discloses tariff exposure from "countries including China and Mexico" but never claims USMCA compliance or exemption. The absence of USMCA compliance language — when SMP in the same SIC code explicitly claims it — strongly suggests Stoneridge's Mexico operations don't qualify. This makes SRI a second data point in the compliance-gap category: a company actively shifting its asset base from the U.S. to Mexico while facing the same tariff headwinds as non-North American imports.

Stoneridge's $6.4 million Juarez restructuring and 67% Mexico asset growth, paired with a 70% collapse in U.S. assets, marks one of the most aggressive asset-base migrations to Mexico visible in recent SEC filings — all without a single mention of USMCA compliance protection.

The Exits and the Second-Order Plays

Not every company is building in Mexico. Universal Electronics announced the closure of its Mexico manufacturing facility in August 2025, framed as part of a cost-reduction restructuring. UEIC reported an operating loss of $6.4 million in 2025 on top of a $15.3 million loss in 2024. Revenue was declining, margins were flat, and the company couldn't justify the overhead of owned Mexico production.

"For example, in August 2025, we announced the anticipated closure of our manufacturing facility in Mexico. The successful implementation of our restructuring activities may from time to time require us to effect business and asset dispositions, workforce reductions, facility consolidations and closures."

But UEIC's exit isn't clean. The company continues to "utilize third-party manufacturers located in Asia and Mexico" even after closing its owned facility. And its risk factors note "significant uncertainty" about whether USMCA exemptions will apply to Mexico imports at all. UEIC is the counter-narrative: a company leaving Mexico not because nearshoring failed, but because unprofitable companies can't absorb the overhead of owned manufacturing in a tariff-uncertain environment. The exposure remains — just transferred from the balance sheet to a supplier contract.

At the other end of the spectrum, STAG Industrial doesn't manufacture anything in Mexico. The industrial REIT owns U.S. warehouse and distribution properties — and explicitly cites nearshoring as a structural demand driver.

"...policies that promote domestic and regional manufacturing 'onshoring and nearshoring,' a desire for greater supply chain resilience and redundancy which is driving higher inventory to sales ratios and greater domestic warehouse demand over the long term (i.e. the shortening and fattening of the supply chain)"

STAG's thesis is elegant: whether companies nearshore TO Mexico or onshore back TO the U.S., both scenarios increase demand for domestic warehouse space. Supply chains get "shorter and fatter," inventory-to-sales ratios rise, and industrial REITs fill more square footage. But the same 10-K reveals a tension: "our acquisition activity has continued to slow since 2022 relative to our historical acquisition pace." STAG cites nearshoring as a long-term demand driver while simultaneously pulling back on capital deployment. That disconnect — bullish thesis, cautious action — suggests that nearshoring's second-order benefits to industrial real estate remain more narrative than operational, at least at current tariff uncertainty levels.

STAG Industrial's positioning as a nearshoring beneficiary is undercut by its own disclosure that acquisition pace has slowed since 2022 — a signal that the supply chain restructuring thesis hasn't yet translated into the warehouse demand that would justify aggressive capital deployment.

The Pattern: USMCA Compliance Is the Real Moat

The USMCA compliance divide is invisible from reading any single company's filing. Teleflex discusses its Mexico investment growth without connecting it to the USMCA gap. Standard Motor Products claims USMCA compliance without comparing itself to non-compliant competitors. Stoneridge mentions tariff exposure from Mexico without disclosing whether it could qualify for exemption. Only by reading across filings does the pattern emerge: companies in the same industries, making similar nearshoring investments, face radically different tariff exposure based on a compliance status that most investors overlook.

This matters because the nearshoring narrative typically treats "manufacturing in Mexico" as a single category. It isn't. SMP's USMCA-compliant Mexico operations occupy a fundamentally different economic position than TFX's non-compliant ones. The compliance gap creates a two-tier manufacturing landscape where the tariff benefit that justifies the nearshoring investment exists for some companies and not others — and the distinction is buried in MD&A language and risk factor disclosures rather than flagged in earnings calls or analyst presentations.

For investors tracking nearshoring Mexico as a theme, three things are observable in future filings:

1. USMCA compliance language in 10-K disclosures. Companies that explicitly claim exemption (like SMP) versus those that disclose tariff impact without claiming it (like TFX and SRI) are telling you which tier they occupy. Watch for new compliance claims — TFX achieving USMCA compliance would materially change its Mexico cost structure.

2. Mexico PP&E trajectory relative to tariff disclosure tone. TFX growing Mexico PP&E 36% while admitting tariff headwinds is a revealed preference that the compliance bet will pay off. Any deceleration in Mexico capital spending from non-compliant companies would signal the bet is souring.

3. Second-order beneficiary capital deployment. STAG's slowing acquisition pace despite the nearshoring demand thesis is a leading indicator. If industrial REITs start accelerating acquisitions, it means nearshoring demand is finally showing up in lease rates and occupancy — the point at which the theme moves from narrative to cash flow.

Frequently Asked Questions

What is nearshoring Mexico and why does it appear in SEC filings?

Nearshoring Mexico refers to companies relocating manufacturing from distant countries (primarily China) to Mexico for proximity to the U.S. market. It appears in 201 operational SEC filings because companies must disclose material manufacturing locations, tariff exposure, and supply chain risks. The trend spans 15+ SIC industries from auto parts to industrial REITs.

Which companies are most exposed to Mexico nearshoring tariff risk?

Teleflex (TFX) has the largest disclosed Mexico manufacturing exposure at $136.4 million in PP&E while explicitly stating its Mexico products are "not currently compliant" with USMCA, meaning they face the same tariffs as non-North American imports. Stoneridge (SRI) grew Mexico assets 67% while disclosing tariff risk from Mexico imports without claiming USMCA exemption.

What is the USMCA compliance divide in Mexico nearshoring?

The USMCA compliance divide is the gap between companies that qualify for tariff exemptions under the United States-Mexico-Canada Agreement and those that do not. Standard Motor Products states its Mexico operations are "mostly exempt from tariffs under USMCA," while Teleflex — investing even more aggressively in Mexico — discloses its products are "not currently compliant." Both are investing in Mexico manufacturing, but only one has tariff protection.

How does nearshoring Mexico affect industrial real estate companies?

STAG Industrial explicitly cites nearshoring as a structural demand driver for U.S. industrial warehouse space. Their thesis: supply chains are "shortening and fattening," driving higher inventory-to-sales ratios and greater domestic warehouse demand. However, STAG's acquisition pace has slowed since 2022, suggesting the nearshoring thesis hasn't yet fully translated into deployed capital.

Are any companies leaving Mexico despite the nearshoring trend?

Yes. Universal Electronics (UEIC) announced the closure of its Mexico manufacturing facility in August 2025 as part of cost-reduction restructuring. The company reported operating losses of $6.4 million in 2025 and $15.3 million in 2024. However, UEIC still uses third-party manufacturers in Mexico, suggesting even companies exiting owned operations maintain supply chain exposure.

Methodology

This analysis used MetricDuck's SEC filing intelligence tools to search 642 total filings (201 operational) across 5 form types for references to nearshoring and Mexico manufacturing. We identified 5 companies with substantive disclosures spanning three strategic postures — USMCA-compliant operations, compliance-gap investment, and exits/second-order plays — and analyzed their filing sections for cross-company patterns.

Tools used: SEC EDGAR Full-Text Search (EFTS) for discovery across all form types, with three separate queries (landscape, operational filter, S-1/DEF 14A angle). MetricDuck filing intelligence for company-level risk and margin analysis. Filing section reader for verbatim evidence extraction from MD&A, business description, risk factors, and segment footnote sections.

Limitations:

• Keyword matching: EFTS searches for "nearshoring" and "Mexico manufacturing" miss companies that describe the same activity using different language (e.g., "North American production footprint" or "regional supply chain optimization"). The 201 filing count is a lower bound.
• USMCA compliance inference: For companies that don't explicitly state compliance status (like Stoneridge), we infer non-compliance from the absence of exemption language and the presence of tariff exposure disclosures. This is not definitive — a company could be partially compliant without disclosing it.
• Date range constraint: This analysis covers filings from March 2024 to March 2026. Companies that began Mexico operations before this window but don't mention nearshoring in recent filings are not captured.
