Management Quality -- 8/10
CMI management earns an 8/10 driven by consistently strong execution on core business commitments,
pragmatic strategic pivots, and transparent communication. The Rumsey/Smith team navigated a historically
difficult 2025 (tariffs + truck downturn + hydrogen bust) while delivering record ex-items EBITDA of
$5.84B (17.4% margin) and expanding margins in growth segments by 250-430bps. Promise delivery rate is
strong at 8 of 11 met or beaten. The primary deductions are: (1) Accelera/hydrogen was a capital
allocation misstep costing ~$1.5B+ in cumulative losses before the pivot, and (2) the 2027 breakeven
target for Accelera appears increasingly unlikely.

Leadership team
Jennifer Rumsey -- Chair and CEO (since 2022)
Rose through engineering ranks over 20+ years at Cummins; VP of Engine Business before CEO.
First female CEO of Cummins. Deep institutional knowledge and strong operational background.
Direct and data-rich on earnings calls. Led pragmatic pivot on Accelera/hydrogen strategy
when the market turned, taking decisive write-downs rather than clinging to a failing thesis.
Mark Smith -- VP and CFO (since 2019)
20+ years at Cummins with deep operational finance background across multiple divisions.
Exceptionally clear on calls -- gives granular color on tariff impacts, segment margins, and
capital allocation trade-offs. His Q3 2025 framing of the "tale of two economies" was honest
and informative. Managed to reach near price/cost neutral on tariffs by Q4 2025.

Of 12 promises tracked, 11 are verifiable. 4 were beaten, 4 were met, 1 was mostly met, 1 was missed
(Accelera losses), and 1 is at risk (Accelera breakeven timeline). This is a strong track record,
particularly given the severe headwinds from tariffs and a ~40% decline in NA truck volumes during 2025.

Execution on Destination Zero strategy
Power Systems / Data Center -- Outstanding
Data center revenue grew from ~$2.6B (2024) to ~$3.5B (2025). Capacity doubled ahead of schedule
on the 95-liter. Power Systems EBITDA expanded from 18.4% (2024) to 22.7% (2025) -- a remarkable
430bps expansion. 2026 guide of 23-24% implies further expansion. This segment is the standout
execution story.
Core Business Strength -- HELM Platform on Track
HELM platform launch (X15N nat gas, X10, B7.2) on schedule. X15 diesel launch planned for 2026
ahead of 2027 regulations. Strong position heading into EPA 2027 cycle. X15N natural gas at full
production with UPS ordering 250 units and Kenworth/Daimler partnerships secured.
Distribution -- Record Margins
Record EBITDA of 14.6% in 2025, up 250bps from 12.1% in 2024. Power generation demand flowing
through the channel. This segment benefits directly from the data center tailwind and demonstrates
the integrated value of the Cummins distribution network.
Accelera Pivot -- Pragmatic but Costly
Management recognized the hydrogen/electrolyzer slowdown and acted decisively -- restructured in
Q4 2024 (fuel cells), took additional electrolyzer charges in Q3-Q4 2025 ($458M total). E-mobility
(bus applications) showing progress toward better unit economics. Pragmatic capital allocation,
not blind commitment to a failing thesis. But cumulative losses exceed $1.5B.

Red flags check
| Flag | Status | Detail |
|---|---|---|
| CEO/CFO turnover | NO | Both Rumsey (CEO since 2022) and Smith (CFO since 2019) are stable, long-tenured insiders. |
| Guidance consistently missed | NO | Track record shows consistent delivery at or above guidance on core metrics. |
| Aggressive accounting | CAUTION | Multiple quarters of Accelera-related charges ($312M in Q4 2024, $240M in Q3 2025, $218M in Q4 2025). However, these are disclosed, explained, and relate to genuine electrolyzer asset write-downs. |
| Insider selling | NO | No unusual patterns noted in transcript commentary. |
| Vague / evasive answers on calls | NO | Both Rumsey and Smith are direct and data-rich. Smith gives granular color on tariff impacts, segment margins, and capital allocation trade-offs. |
| Capital misallocation | MODERATE | Accelera investments (~$764M loss in 2024, ~$438M ex-charges in 2025) represent significant capital into hydrogen/electrolyzers that has not panned out. However, management has pivoted aggressively. |
| Balance sheet risk | NO | Deleveraged post-Meritor acquisition. Net debt/EBITDA below 1x by Q3 2025. A-credit rating maintained. |
| Overreliance on single growth driver | LOW-MODERATE | Data center is the dominant growth narrative, but business is genuinely diversified (5 segments, global presence). Aftermarket provides recurring revenue base. |
| Guidance suspension | YES (justified) | Suspended full-year guidance Q1-Q3 2025 due to tariff uncertainty. Reinstated for 2026 at Q4 2025. Industry-wide phenomenon (Caterpillar, PACCAR also withdrew). |
No major red flags. Primary watch items: Accelera capital allocation (~$1.5B+ cumulative losses),
guidance suspension in 2025 (industry-wide, justified by tariff uncertainty), and moderate data center
concentration risk. Clean on CEO/CFO stability, insider selling, and analyst communication quality.
Qualitative assessment
Exceptional Execution Through Severe Downturn
Navigated NA truck volumes down ~40% YoY in some quarters while simultaneously delivering record
margins in Power Systems (22.7%) and Distribution (14.6%). Achieved 2030 financial commitments
ahead of schedule per the Q4 2025 call. Tariff impact managed to near price/cost neutral by Q4 2025.
Pragmatic Accelera Pivot
Not clinging to hydrogen thesis when market turned. Decisive write-downs and cost cuts across
fuel cells (Q4 2024) and electrolyzers (Q3-Q4 2025, $458M total). E-mobility bus applications
showing progress toward better unit economics. This is pragmatic capital allocation -- recognizing
when to cut losses.
Strong Capital Return and Dividend Track Record
16 consecutive annual dividend increases with a 10% hike to $2/share in Q2 2025. Long-standing
commitment to return ~50% of operating cash flow. Buybacks paused in 2025 for balance sheet repair
post-Meritor, now signaling flexibility for 2026. Disciplined framework consistently honored.
Clear, Transparent Communication
Smith gives granular color on tariff impacts, segment margins, and capital allocation trade-offs.
Rumsey is direct about strategic priorities and uncertainties. IR transition from Clulow to Arens
was orderly and pre-announced. Management bench appears strong across all five segments.
Accelera Remains a Significant Cash Drain
Cumulative losses exceed $1.5B across 2024-2025. The electrolyzer business was a strategic misstep
that consumed meaningful capital before the pivot. 2026 guide of -$325M to -$355M shows narrowing
but 2027 breakeven target appears increasingly unlikely given the hydrogen market deterioration.
2025 Guidance Suspension
Suspended full-year guidance for Q1-Q3 2025 due to tariff uncertainty, leaving investors without
formal targets for most of the year. This was industry-wide (Caterpillar, PACCAR also withdrew),
so it is not a management credibility issue, but it limited visibility during a turbulent period.
Guidance was reinstated for 2026 at the Q4 2025 call.
Score rationale
8/10. CMI management earns an 8 for consistently strong execution on core business
commitments, pragmatic strategic pivots, and transparent communication. The Rumsey/Smith team navigated
a historically difficult 2025 -- tariffs, a ~40% NA truck volume decline, and the hydrogen market bust
-- while delivering record ex-items EBITDA of $5.84B (17.4% margin) and expanding margins in Power
Systems by 430bps and Distribution by 250bps. The promise delivery rate is strong: 8 of 11 verifiable
commitments met or beaten.
Why not higher: (1) Accelera/hydrogen was a capital allocation misstep that cost ~$1.5B+ in cumulative losses before the pivot. While the speed and decisiveness of the write-downs demonstrate good management instincts, the initial bet consumed significant capital on a thesis that did not materialize. (2) The 2027 Accelera breakeven target appears increasingly unlikely. (3) Guidance suspension in 2025 (though justified and industry-wide) limited investor visibility.
What would move this to 9: Accelera losses narrowing to the -$325M to -$355M 2026 guide range with a credible path to breakeven, sustained delivery on 2026 guidance (revenue +3-8%, EBITDA 17-18%), Power Systems EBITDA reaching the 23-24% guided range, and resumption of buybacks demonstrating confidence in balance sheet flexibility. The core business execution is already at a 9+ level -- it is Accelera that holds the composite score at 8.
