James Hardie's valuation gap divides fund managers as AZEK integration progresses

L1 Capital, Perpetual Asset Management and Plato Investment Management detail opposing reads on the discount

13 Jul 2026 · 7 min read

James Hardie has spent 2026 trading as a proxy for the US housing cycle, swinging from a sharp sell-off during the Iran conflict to a strong recovery as mortgage rates eased, all while integrating its largest-ever acquisition.

Pendal Group said in a Newsletter in July 2026 that subdued US housing data, flat mortgage applications with 30-year rates around 6.6%, and existing home sales down from 4.19 million in May to 4.09 million in June, with affordability rather than supply the key constraint, points to a modest drag on US residential investment, a headwind for housing-related building products exposure such as James Hardie.

The AZEK deal: bought at the wrong moment, or the right price

L1 Capital gave the fullest account of why the market punished James Hardie's AZEK acquisition in a Presentation in June 2026, saying the market's reaction to the 2025 deal created what the manager believes is a compelling investment opportunity, with the stock falling from around $55 to below $30 as investors questioned both the timing and the price paid.

The manager said it established the majority of its holding at around 15 to 16 times forward earnings, well below the company's long-term average of around 21 times, and argued earnings are currently depressed, with US housing statistics around 10% below long-term averages, meaning investors get exposure to a high-quality business with meaningful upside if housing activity normalises.

When we put those factors together, we think James Hardie offers a compelling combination of valuation support, earnings upside, and identifiable catalyst for value creation.

Blackwattle Investment Partners described the integration progress in a Monthly Report in June 2026, noting it added the stock in November 2025 when it fell for technical reasons, an MSCI index exclusion, rather than any fundamental development, and that the position has since re-rated from around 15 times 2027 earnings to over 20 times as the AZEK integration progressed well. The manager said James Hardie's FY26 result showed a 25% year-on-year increase in net sales to US$4.8 billion, with management targeting free cash flow conversion above US$500 million by FY27, up from US$314 million in FY26.

The Iran conflict sell-off, and the case managers made through it

The stock's sharpest test came in March 2026. L1 Capital said in a Quarterly Report that James Hardie declined during the period as rising inflation expectations and higher mortgage rates weighed on the housing outlook, and while the company has no direct exposure to the Iran conflict, given approximately 80% of sales are generated in North America, it may face indirect pressures from softer consumer confidence and elevated input costs. The manager said the stock traded at around 15 times forward earnings, a notable discount to its 10-year average of 21 times, presenting what it called an attractive entry point.

Perpetual Asset Management described the same period in a Monthly Report in May 2026, saying sentiment turned sharply negative for cyclical names such as James Hardie following the onset of the conflict, with the share price declining 23.7% over March. When the share price reached the mid-to-high twenties, the manager said it believed the risk-reward was significantly skewed to the upside and added to its position, making James Hardie one of its largest active weights.

By the end of May, the manager said a combination of James Hardie's FY26 full-year results and easing geopolitical tensions saw the stock return 9.7% for the month, with the manager continuing to believe the business remains undervalued relative to a mid-cycle environment, a mispricing it attributes to near-term sentiment weighing on the multiple rather than any structural deterioration.

You take a name like James Hardie, which yes, it does have residential exposure, but it de-rated to about 14 times earnings. And it usually typically trades on 20-plus times earnings. So when we look at a name like that, we think we're getting it at a very favorable valuation.

Not every manager agrees the discount is a buying opportunity

Plato Investment Management took the opposing view in an Article in May 2026, with portfolio manager David Allen saying his Global Alpha Fund is betting against James Hardie, arguing the large falls in blue chip names reflects more the fact they were far too expensive in the first place, and that sanity is returning to the market.

ECP Asset Management laid out the operational concerns behind that scepticism in a Monthly Report in March 2026, saying James Hardie underperformed as the US housing market continued to contend with persistent affordability challenges and a softening labor market, with organic volume declines in siding and trim despite higher average selling prices, and repair and remodel growth of only around 2.4%, leading management to close two US facilities to better size the cost base.

The recovery, and three drivers L1 Capital points to for what comes next

As tensions eased, the recovery was rapid. L1 Capital said in a Quarterly Report in June 2026 that James Hardie shares recovered 46% over the quarter following easing Middle East tensions and management's release of a constructive FY27 outlook, which included a pathway to return the core North American fibre cement business to volume growth despite a subdued US housing market.

The manager outlined three drivers it sees supporting further share price upside: a depressed housing cycle with option value on recovery, given US single-family housing starts running around 15% below the long-term average; company-specific growth levers including AZEK synergy delivery, expected to reach US$125 million of run-rate commercial revenue synergies by the end of FY27, and balance sheet deleveraging toward a targeted 2.0 times net leverage by the second quarter of FY28; and a valuation the manager still considers favourable relative to history, given the market continues to apply a discounted multiple to reflect recent execution, governance and housing-cycle concerns.

What managers are watching next

With Pendal flagging in July 2026 that US existing home sales and mortgage applications remain subdued, and L1 Capital pointing to AZEK synergy delivery and balance sheet deleveraging as the near-term catalysts, the managers who added through the Iran-driven sell-off say the key test now is whether James Hardie's North American fibre cement volumes return to growth in FY27 as management has guided, even as the broader US housing cycle stays depressed.
