Heartland Bets on MSA Safety Margin Recovery

Heartland Advisors' Opportunistic Value Equity Strategy returned 12.32% in the second quarter of 2026, trailing the Russell 3000 Value Index's 14.02% gain, and used the quarter to build a new position in MSA Safety Incorporated (NYSE:MSA), the workplace safety equipment maker it expects to deliver multi-year margin expansion.

The fund's Q2 2026 investor letter frames the addition against a difficult stretch for the company. MSA's stock closed at $177.25 per share on September 21, 2026. The shares declined 5.56% over the past month but gained 3.00% over the past year. The company carries a market capitalization of $6.83 billion, with the stock trading in a 52-week range of $151.11 to $208.92.

Why the fundamentals have been choppy

Heartland's letter lays out a clear diagnosis of MSA's recent underperformance. "MSA's fundamentals have been choppy in recent years against a backdrop that has favored AI infrastructure exposure over more mature industrial equipment makers," the firm wrote.

Two specific headwinds hit the Fire Service segment last year. Sales suffered from the timing of Federal Assistance to Firefighters Grants (AFG) and from the government shutdown in the fourth quarter of 2025. Both factors fell outside management's control, but they compounded a broader problem: pricing.

"Management has been slow to raise prices in a volatile inflationary backdrop as it prefers to push permanent pricing actions through the company's distribution channel," Heartland stated. That deliberate approach carried a cost. Sales in 2025 rose less than 4%, while operating profit margin fell 0.8%.

The margin case

Heartland's thesis rests on MSA's two highest-margin products: portable gas detectors and firefighter self-contained breathing apparatus (SCBA). "We expect MSA's profit margin to expand in the coming years driven by its two highest-margin products," the letter reads.

The SCBA business ties directly into the Fire Service segment, where grant timing and the 2025 government shutdown disrupted sales. If federal funding flows normalize, that pent-up replacement demand could convert into revenue. Portable gas detectors, sold across industrial end markets, give the company a second high-margin lever independent of the fire service cycle.

A quarter of narrow leadership

The MSA position also reflects Heartland's broader stance on a market it describes as deceptively strong. Second-quarter indices signaled a broadening market, but strong performance concentrated in a limited range of technology infrastructure and semiconductor stocks, according to the letter.

Heartland's own results illustrate that dynamic. Security selection was positive in nine of eleven sectors, led by Communications, Materials, and Industrials. Negative stock selection within Technology offset those gains and left the strategy 1.70 percentage points behind its benchmark.

Rather than predicting how long AI infrastructure spending will run, the firm says it focuses on businesses offering significant upside potential with downside protection. MSA fits that mold: a mature industrial equipment maker with pricing power it has not yet fully exercised and product lines where replacement cycles, not AI budgets, drive demand.

The so-what

The position sizes the bet clearly. At $177.25, MSA trades well below its 52-week high of $208.92, and Heartland is underwriting a recovery in operating margin from a 0.8% decline in 2025. The fund's conviction rests on whether portable gas detectors and SCBA replacement demand can lift profitability faster than the company's cautious, channel-based pricing approach has done. If grant funding stabilizes after the 2025 disruption, Heartland's letter suggests the Fire Service segment becomes a tailwind rather than the drag it was last year.
