Week 4: Most Interesting D-Sheets from the Past Week
Week of Apr 27 – May 3, 2026 | Featuing $ORN, $BAND, $ROG, $AEP.V & $TTEK
Here are the InfoArb Tear Sheets we think you should pay the most attention to, where the differences between press releases and earnings calls are dramatic because they outline new catalysts, trends, and clarify misconceptions from just reading the press release.
These summaries are created to help you speed up your research on interesting companies. They are not buy/sell recommendations.

[ORN] — Orion Group Holdings, Inc. 🟢 Strong Signal
Description
U.S. specialty construction company with two segments — Marine (dredging, ports, defense marine) and Concrete (data centers, advanced manufacturing). ~$434M cap, $216.3M Q1 revenue.
Set-up
Q1 was a mix-shift inflection. Concrete posted a "high watermark" at $106M revenue and $8.6M adjusted EBITDA (vs. $61.5M / $2.8M a year ago), with data centers ~40% of Concrete revenue and Orion having completed 50+ data centers. Marine declined on project ramp-down timing, which management said is not persistent margin degradation. The forward setup is the real story: >$200M of April awards not yet in the $668M quarter-end backlog (including a $100M port renovation, $40M dredging, and $24M data center project) and a $24B pursuit pipeline split across 2026/2027/2028+.
Information arbitrage
Backlog understated by $200M+ — The $668M quarter-end figure excludes April awards already captured but not yet contracted, meaningfully understating Q2 backlog.
Marine weakness is phasing, not demand — Declines reflect ramp-down of completing projects, not pricing deterioration; a Marine recovery would compound on Concrete strength.
Defense/maritime infrastructure optionality — The call tied Marine to naval superiority, shipyards, and maritime security, an angle that could drive multiple expansion.
Risks
Consolidated EBITDA margin was only 4.0% in Q1, so reaching full-year guidance ($54–58M vs. $8.7M Q1) requires a meaningful back-half ramp; thesis depends on April awards converting cleanly and Marine margins recovering.
[BAND] — Bandwidth Inc. 🟢 Strong Signal
Description
Cloud communications software for voice, messaging, and emergency services, increasingly positioned as AI voice agent infrastructure. ~$534M cap, $208.8M Q1 revenue.
Set-up
Clean beat-and-raise — record Q1 revenue of $209M (+20%) and EBITDA of $26M (+17%), with full-year guide raised to imply 18% revenue / 31% EBITDA / 26% non-GAAP EPS growth at midpoint. Five of six 2025 large enterprise wins are still less than 50% deployed (one already at ~120% of initial contract value), meaning signed business is still ramping. Salesforce AgentForce reframes Bandwidth as critical CRM-layer infrastructure, and management said it's not yet meaningfully in numbers.
Information arbitrage
Software services ARR exit rate up 67% — Software services nearly doubled with ARR exit rate at $25M, a quietly emerging margin-durability lever the press release does not flag.
AI monetization is per-interaction, not per-minute — Voice AI creates multiple usage components per call, structurally changing how the business gets paid.
Messaging strength is non-political — Q1 messaging growth was not driven by political traffic, so the rebound is cleaner quality than typical mid-cycle recoveries, with political tailwind still ahead in H2.
Risks
GAAP EPS was -$0.08 and Q1 FCF was only roughly breakeven, so non-GAAP is running well ahead of GAAP and cash; AI voice and AgentForce contributions are still a forward narrative.
[ROG] — Rogers Corporation 🟢 Strong Signal
Description
Engineered materials supplier into industrial, automotive (radar, EV batteries), aerospace/defense, and electronics/communications. ~$2.01B cap, $200.5M Q1 revenue.
Set-up
Textbook "margin recovery ahead of revenue recovery." Q1 revenue grew only 5.2% (most from FX), but adjusted EBITDA jumped to $32M from $19.5M, with EBITDA margin expanding 580bps to 16.0%. Adjusted EPS more than doubled to $0.75. Q2 guidance implies further sequential improvement (revenue $210–220M, EPS $0.90–1.10, EBITDA $35–41M). Management quantified $45M cumulative cost savings potential, including Germany restructuring, with capacity sufficient for 6–8 quarters — meaning incremental revenue flows through with minimal capex drag.
Information arbitrage
Automotive design wins have a quarterly bridge — EV battery and automotive radar wins begin converting to revenue across Q2/Q3/Q4 2026, turning a current drag into a scheduled recovery.
Industrial is the quietly dominant segment — Industrial is now 37% of sales (largest segment) and grew double digits on PMI improvement and semiconductor demand, making the recovery less EV-dependent.
Data center is option value with low cost — Microchannel cooler testing positions Rogers in AI thermal management, but management was explicit on late-2027 material contribution — the option isn’t in numbers yet.
Risks
Reported 5% sales growth was helped by $7.9M of FX; weather/supplier disruptions flattered the call's "would have been at high end" framing; the AI/data center catalyst is pushed to late 2027.
[AEP / APEUF] — Atlas Engineered Products Ltd. 🟡 Moderate Signal
Description
Canadian building-products consolidator focused on roof trusses, floor trusses, wall panels, and engineered wood for residential construction. ~C$28.9M cap, C$17.6M Q4 revenue.
Set-up
A share-and-capacity story during a weak pricing cycle. FY2025 revenue grew 12% but adjusted EBITDA margin fell from 15% to 11% as management sacrificed price to keep plants utilized. Forward catalysts are concrete: Q1 2026 quoting exceeded C$80M with C$21M+ of signed orders (vs. C$11M prior year), weather-delayed Q1 shipments should compress into Q2/Q3, and the Clinton robotic truss facility is on track for early-July operation with the C$4M federal grant paperwork submitted and only ~C$3.5M of remaining capex.
Information arbitrage
CEO surprised by demand strength — Management said the Q1 order level was a positive surprise and explicitly framed the C$21M+ as signed contracts, not “wishful thinking” — a tone shift worth noting from a team that’s been cautious on pricing.
Margin sacrifice is deliberate share-grab — Lower pricing keeps staff busy and gains share while single-province rivals struggle — could reverse meaningfully if pricing normalizes post-winter.
Clinton is more than capacity — Management tied the robotic facility to lower lumber waste, better precision, and higher efficiency — positioning it as a margin lever, not just volume.
Risks
FY2025 normalized EBITDA actually declined ~C$1.6M YoY despite revenue growth; pricing recovery is not guaranteed; catching up delayed shipments could strain labor and working capital; at C$28.9M cap there’s little room for execution slips.
[TTEK] — Tetra Tech, Inc. 🟡 Moderate Signal
Description
High-end engineering and consulting firm focused on water, environmental services, sustainable infrastructure, and defense infrastructure for federal/state/local/commercial customers. ~$7.77B cap, $1.22B Q2 revenue.
Set-up
Reported revenue declined YoY on USAID/State Department cuts and absent disaster work, but underlying net revenue grew 8%, EBITDA margin expanded 90bps to 12%, and adjusted EPS exceeded the high end of guidance. Backlog grew 8% sequentially to $4.28B — management called this an "inflection point" tied to federal budget clarity releasing defense task orders — and FY2026 guidance was raised. Defense contract capacity rose $650M+ in the quarter, fixed-price work is now ~48% of net revenue (up from 37% in 2023), and DSO improved to 58 days with a path toward 50.
Information arbitrage
Data center feasibility pipeline — 20+ active feasibility assessments for data center developers, where water/power/permitting bottlenecks are the binding constraint on new builds — Tetra Tech is positioned upstream of construction.
Fixed-price mix shift compounds margin — The 37% to 48% shift carries higher margins and lower working capital, so the same revenue dollar produces more EBITDA and more cash than three years ago.
Ukraine reset already in numbers — Q2 included ~$61M of USAID work primarily Ukraine-related, but H2 guidance assumes only ~$20M/qtr — the step-down is embedded.
Risks
Reported revenue is still down YoY and the "ex-USAID/disaster" framing requires accepting management's adjustments; state/local growth guidance was lowered; commercial softness from offshore wind wind-down is real; at $7.77B cap this is the upper end of mandate.
