Grupo Simec S.A.B. de C.V

What it is

Grupo Simec was founded in 1934 and is headquartered in Guadalajara, Mexico. It melts scrap steel in electric-arc furnaces — so-called mini-mills — and rolls it into two main product families: structural steel (the beams and angles used in buildings and bridges) and special bar quality (SBQ) steel, a precision grade machined into engine components.

Its Mexican plants are in Mexicali, Guadalajara, Tlaxcala and San Luis Potosí; its U.S. segment runs seven plants, six of them in Ohio, Indiana and New York. The group is also present in Brazil and the Netherlands through subsidiaries.

Who owns it

Industrias CH, S.A.B. de C.V., controlled by the chairman of Simec’s board, Rufino Vigil González, owns 76% of Simec’s shares as of December 31, 2024.

The structured data shows insiders collectively hold 77.9% of shares, leaving only about 22% in public hands — which keeps the stock lightly traded.

As a result of Industrias CH’s significant equity position, there is currently limited liquidity in Simec’s series B shares and its American Depositary Shares. For outside investors, that thin float is the central trade-off: tight control brings stability, but the shares rarely move in large volumes.

Who runs it

Sergio Vigil González, CPA, has served as Chief Executive Officer of Grupo Simec since July 5, 2024. He is the brother of the controlling shareholder and board chairman, Rufino Vigil González — so strategy at Simec and its parent Industrias CH flows through one family.

Sergio Vigil González had in previous years exercised a senior role in Simec’s management despite having no formal role in the company; since July 2024, he is its Chief Executive Officer. The Finance Coordinator named in company filings is Mario Moreno Cortez.

The money, in plain words

Sales ran at MXN 30.5 bn (USD 1.76 bn) over the trailing twelve months — down roughly 9% from the MXN 33.7 bn (US$1.9 bn) recorded in 2024 (our calculation). Net sales fell 10% because of 6% fewer shipments of finished steel and a 4% lower average selling price, dropping from MXN 33,658 million (US$1.9 bn) in 2024 to MXN 30,291 million (US$1.7 bn) in 2025.

The company keeps about 6 cents of profit from every peso of sales — a net margin of 6.3%, modest for a manufacturer but understandable given the steel cycle. Return on equity of 3.1% looks low, but the number is distorted by an enormous cash pile: the balance sheet holds MXN 28,545 million (US$1.6 bn) in cash with minimal listed debt of MXN 5.4 million (US$311 k) in old medium-term notes — meaning the net cash position of MXN 28.5 bn (USD 1.64 bn, our calculation) is equal to roughly a third of the entire market value.

Shareholders are, in effect, part-owning a bank account at a big discount.

At a price-to-earnings ratio of 8.2×, the market is paying just over eight pesos for every peso of annual earnings — low by any regional benchmark. No dividend is currently paid, so all the value must come from the stock price.

What it is doing now

Simec had a tougher 2025: net sales fell 10% to MXN 30,291 million (US$1.7 bn), driven by 6% lower steel shipments and a 4% decline in average prices. Net income attributable to controlling shareholders dropped 86%, mainly because a prior-year net exchange gain of MXN 5,556 million (US$320 mn) turned into a net exchange loss of MXN 3,607 million (US$208 mn), swinging the financial result sharply negative.

The operating business itself — before currency swings hit the bottom line — held up: operating profit as a percentage of net sales represented 18% in 2025, up from 16% in 2024.

The 2024 U.S. elections resulted in a shift toward more protectionist policies, including the reinstatement of Section 232 tariffs on all steel imports effective March 2025. For Simec, which sells into the U.S. market from both Mexican and American plants, the net effect on cross-border flows bears watching in every coming quarter.

What to watch

• Currency. The peso-dollar swing made and then destroyed more than MXN 9 bn (US$518 mn) of net income across two years. The reported profit figure tells you less than usual here; watch the operating result.
• U.S. tariffs. The automotive market accounted for approximately 11% of Simec’s SBQ net sales in 2024 — and any further trade barriers between Mexico and the U.S. hit both the SBQ and structural steel lines.
• The cash mountain. At MXN 28.5 bn (USD 1.64 bn) — more than half of annual revenue sitting in cash — the question every outside shareholder wants answered is: acquisition, dividend, or indefinite accumulation?
• Governance. With 76% controlled by one family and a long-running history of material weaknesses flagged in internal controls, minority shareholders have limited recourse. That is the price of the discount.
