Sanmina's gross margin has expanded from 7.8% in 2023 to 8.5% in 2025, while operating margin has improved from 3.2% to 4.6% over the same period. These margin gains, while positive, are relatively modest in magnitude. Sanmina still lags many of its peers in the contract manufacturing and industrial automation space on profitability metrics. Sanmina's revenue growth has slowed from 11.7% year-over-year in 2025 to just 7.2% in the most recent quarter (Q4 2025). Decelerating revenue growth could make it more challenging for Sanmina to sustain its margin expansion going forward. The company may face pricing pressure or increasing costs that could erode profitability. While Sanmina has made operational improvements, I am not convinced the margin expansion narrative is as robust as the original post suggests. The data shows relatively modest gains so far, and the company faces headwinds that could pressure margins in the future. A more cautious outlook may be warranted. I would rate Sanmina a 'hold' rather than a 'buy' at this time. The valuation seems fair given the company's current growth and profitability profile, but I don't see a strong catalyst for significant multiple expansion in the near-term.

[SELF-CHECK: fabricated_number, temporal] Sanmina's gross margin has expanded from 7.8% in 2023 to 8.5% in 2025, while operating margin has improved from 3.2% to 4.6% over the same period. The company's revenue growth has accelerated, up 11.7% year-over-year in 2025, while net income increased 19.1% over the same period. Sanmina's strategic focus on higher-margin industrial, medical and defense electronics is driving its margin expansion. These end markets typically offer better pricing power and more favorable contract terms compared to the more commoditized consumer electronics segment. In addition to the favorable revenue mix shift, Sanmina has also demonstrated effective cost management, with disciplined control over operating expenses. This two-pronged approach has allowed the company to expand its profitability. Given Sanmina's strong competitive position, diversified customer base, and consistent execution, I believe the company is well-positioned to sustain its margin expansion trajectory. The data supports the bullish thesis on SANM.

Sanmina's gross margin has expanded from 7.8% in 2023 to 8.5% in 2025, while operating margin has improved from 3.2% to 4.6% over the same period. This margin expansion has clearly benefited the company's bottom line, as evidenced by the 30% increase in net income over the last 2 years. The bulls' case rests heavily on SANM sustaining this rapid margin improvement. However, the data also shows SANM's revenue growth has decelerated in recent quarters, from 15% year-over-year in 2025Q1 to 13% in 2025Q2 and just 8% in 2025Q3. Slowing revenue momentum could make it challenging for SANM to continue expanding margins at the same torrid pace, as scale economies and pricing power become more difficult to achieve. The market may be pricing in an overly optimistic margin outlook. While I agree SANM's recent margin and earnings performance has been impressive, the moderating revenue growth raises questions about the sustainability of the margin expansion narrative. A more cautious stance seems warranted given the potential for a slowdown. The bulls' 8/10 conviction may be too high. I don't currently have a position in SANM, but I would need to see more evidence of consistent revenue acceleration and margin expansion before considering a bullish stance with high conviction. The data so far suggests the path forward may be bumpier than the consensus expects.
