NN Inc. Earnings Call: Margins Rise Amid Constraints

NN Inc ((NNBR)) has held its Q4 earnings call. Read on for the main highlights of the call.

NN Inc.’s latest earnings call struck a cautiously optimistic tone, as management highlighted sharp margin gains, successful restructuring, and a pivot toward higher-value markets despite modest revenue slippage and a still-stretched balance sheet. Executives framed 2025 as a transition year, with most heavy lifting done and the company now positioned to invest more aggressively for growth heading into 2026.

Improved Profitability and Margin Expansion

Adjusted operating income jumped to $14.2 million for fiscal 2025, an increase of $9.1 million and roughly 179% year over year on a pro forma basis. Adjusted EBITDA reached $49.0 million for the year and $12.9 million in the fourth quarter, lifting margins to 11.6% for the full year and 12.3% in Q4 as the company leaned into higher-margin programs.

Gross Margin Progress Toward Multi-Year Target

Gross profitability continued to edge higher, with adjusted gross margin at 18.8% in the fourth quarter and 18.5% for the full year. Management reiterated a five-year goal of reaching 20% adjusted gross margin and pointed to recent improvements as evidence that the plan is working even with modest revenue pressure.

Successful Transformation and Cost-Out Achieved

NN closed and consolidated four plants and right-sized its workforce by around 800 employees, completing what management called the heavy spending phase of its transformation. Those actions produced about $15 million of cost savings in 2025, with SG&A trimmed to 10.9% of sales and another $10 million of reductions targeted for 2026.

New Business Momentum and Large Pipeline

The company reported more than $200 million of new business wins since mid-2023 and highlighted an $800 million pipeline of opportunities it views as high quality. Management expects to chase $70 million to $80 million of fresh awards in 2026 and plans to launch over 100 programs next year to convert that pipeline into revenue.

Segment-Level Wins and Mix Improvement

Power Solutions was a standout, with full-year pro forma net sales up 5.3% to $178.6 million and adjusted EBITDA climbing about 10.8% to $30.7 million. Mobile Solutions delivered notable margin expansion in the fourth quarter, with adjusted EBITDA margin rising to 16.9% as NN exited dilutive work and shifted toward more profitable business.

Return to Sales Growth Guidance for 2026

After a period of portfolio rationalization and program transitions, management now forecasts a return to top-line growth in 2026. The company guided to net sales between $445 million and $465 million, signaling confidence that new program ramps and better mix can offset recent volume pressure.

Capital Allocation Shift to Growth

With restructuring largely behind it, NN is reallocating capital toward expansion and program launches rather than footprint consolidation. Net capital spending is expected to roughly double from about $10 million in 2025 to around $20 million in 2026, with more than three-quarters earmarked for growth-related equipment and launches.

First Entry into Data Center Market

Management spotlighted its first win in the data center arena, supplying watertight couplings for water-cooled computing equipment in a market it views as strategically important. The ramp-up is described as immediate and high-margin, and NN signaled that data centers will be a core target as it tilts the portfolio toward faster-growing, higher-value sectors.

Full-Year Revenue Decline and Demand Pockets

As-reported net sales for 2025 came in at $422.2 million, down $42.1 million from the prior year and softer than management had hoped. On a pro forma basis that adjusts for divestitures and rationalized volumes, revenue declined by about $7.4 million, or 1.7%, underscoring that margin gains are still outpacing top-line momentum.

Continued Exposure to Weak Auto Markets

The biggest drag remained NN’s exposure to North American auto demand through its Mobile Solutions segment, where a weak backdrop and a large customer pulling volume hurt results. Pro forma net sales in Mobile Solutions fell roughly 9.3% for the year and adjusted EBITDA slipped about 4%, even as mix improvements aided margins late in the year.

Capital Structure Constraints and Strategic Review

Despite better operations, NN remains hampered by an over-levered capital stack that includes substantial debt and preferred equity. The board has formed a committee to review financial and strategic options, but no specific remedy has been announced, leaving investors watching for potential recapitalization or other actions.

Market Volatility, External Headwinds and Restructuring Costs

Management cautioned that tariffs, commodity price swings, geopolitical tensions, and ongoing supply-chain disruptions continue to inject volatility into demand and costs. The recent transformation, including plant closures and workforce reductions, carried material severance and restructuring expenses, though executives emphasized that most of those near-term headwinds are now behind the company.

Forward-Looking Guidance and Long-Term Targets

For 2026, NN is guiding to net sales of $445 million to $465 million, further gross margin and adjusted EBITDA expansion, and $70 million to $80 million in new business wins supported by the $800 million pipeline and more than 100 program launches. Longer term, management is targeting roughly 20% adjusted gross margin, a 13% to 14% adjusted EBITDA margin, and a pathway to about $80 million of adjusted EBITDA by 2030, implying high single-digit annual growth from current levels.

NN Inc.’s earnings call portrayed a company that has largely finished restructuring and is now leaning into growth in more attractive end markets, even as revenue and auto-related exposure remain areas to watch. For investors, the story now pivots to execution on the new business pipeline, delivery on 2026 growth guidance, and progress on addressing the capital structure that still weighs on the equity story.
