M&A Advisory in New Hampshire
New Hampshire eliminated its Interest & Dividends Tax on January 1, 2025 — making it the only New England state with zero tax on wages, capital gains, and investment income, turning the Nashua-Manchester corridor into Boston's tax-free M&A overflow market.
New Hampshire's M&A Economy
New Hampshire's lower middle market operates as a tightly integrated extension of Greater Boston's capital ecosystem, generating roughly $125–128B in nominal GDP in 2025 (BEA: $121.2B in 2024; Q3 2025 real GDP $97.5B SAAR). With approximately 146,000 total business establishments and an estimated 4,200–4,800 LMM businesses in the 20–999-employee range, NH punches well above its size in deal activity. LMM volume nationally fell ~27% through Q3 2025 amid tariff and rate uncertainty, but NH valuations held at 5–7x EBITDA for sub-$25M EV targets and 6–9x for quality platforms in the $25M–$100M EV range. Activity is concentrated in three corridors: the Merrimack Valley (Manchester-Nashua precision manufacturing and defense electronics), the Seacoast (Portsmouth life sciences and SaaS), and the border markets (Salem-Nashua capturing Massachusetts consumer and retail spillover). NH's defining structural advantage is the January 1, 2025 full repeal of the Interest & Dividends Tax — completing the state's transition to a true zero-individual-income-tax jurisdiction and ranking it #3 on the Tax Foundation's 2026 State Tax Competitiveness Index. Boston-based PE platforms and strategics routinely route add-ons through NH to capture no-income-tax positioning for portfolio companies and executive relocation. With PE dealmaker confidence surging from 48% to 86% by year-end 2025 and $1.1T–$3.2T in U.S. dry powder, the 2026–2028 delayed-exit wave is expected to produce the deepest NH LMM pipeline in a decade.
New Hampshire at a Glance
Key Markets in New Hampshire
Manchester MSA
NH's largest city and economic engine; dominant M&A hub housing ARMI/ReGen Valley Tech Hub (recipient of $44M EDA investment), Elliot Health System, DEKA Research (Dean Kamen), SilverTech, and Southern New Hampshire University. Hillsborough County leads the state in industrial jobs (29,531). The Manchester Millyard — 30 buildings along the Merrimack River — is the center of the state's advanced-manufacturing and defense-electronics ecosystem, drawing Boston PE platforms including Audax Private Equity and Berkshire Partners.
Nashua-Milford Corridor
Bedroom community to Boston with the heaviest defense/aerospace concentration in New England outside of Boston. Home to BAE Systems' largest U.S. footprint (6,000+ employees), Elbit America (JETS II prototype), Omron Microscan, and Hitchiner Manufacturing (Milford). Strong cross-border capital flows from MA-based PE targeting NH-domiciled assets to capture tax arbitrage — the I-93/I-95 corridor puts Nashua 45 minutes from Boston's Financial District. National PE firms ran 35+ tracked transactions through this corridor in 2024–2025.
Portsmouth-Seacoast MSA
Affluent Seacoast hub anchored by Pease International Tradeport, a 3,000-acre mixed-use development on a former air force base. Life sciences corridor with Lonza (813,000-sf CDMO campus), Thermo Fisher, Novocure, and Vertex's adjacent Type-1 diabetes cell-therapy facility. Strong tech/SaaS cluster including Bottomline Technologies, PixelMEDIA, and Optiv attracting PE roll-ups. Sig Sauer (Newington, 1,630 employees) is NH's largest manufacturer and anchors a defense supply chain that spans the entire Seacoast region.
Concord-Lakes Region
State capital and mid-sized service economy with insurance, healthcare, and government-adjacent services as anchors. Fidelity Investments maintains a major regional hub in Merrimack (adjacent to Concord). The Lakes Region — Laconia, Meredith, and Wolfeboro — supports a significant hospitality, marine services, and outdoor-recreation economy that attracts consumer-focused PE platforms seeking summer/winter destination assets with recurring regional demand and seasonal EBITDA normalization opportunities.

New Hampshire M&A benchmarks vs. neighboring states.
New Hampshire Deal Landscape 2025-2026
NH LMM deal volume declined approximately 27% through Q3 2025 versus 2024 amid policy uncertainty and tariff volatility, but pricing held firmly at 5–7x EBITDA for typical transactions and 9–13x for differentiated defense-electronics platforms. The dominant buyer profile is Boston-metro PE platforms reaching north — Audax Private Equity, Berkshire Partners, Great River Capital, HCI Equity Partners, Riverside Company, and Carlyle (via Hilb Group) — supplemented by family offices from Hanover (Tuckerman Capital, Focus Acquisition Partners) and Rye Beach (Stony Creek Capital). PE dealmaker confidence surged from 48% at the start of 2025 to 86% by year-end, with $1.1T–$3.2T in dry powder awaiting deployment. The biggest driver entering 2026: delayed founder exits from the 2022–2025 backlog colliding with PE pressure to deploy capital into NH's defense, advanced manufacturing, and recurring-revenue services targets.
Boston PE Platforms Routing Add-ons Through NH's Tax Corridor
Boston-headquartered sponsors are systematically using NH targets as platform anchors and tuck-ins to capture the state's no-income-tax, no-capital-gains-tax structure. Audax Private Equity (1,692 lifetime investments) holds Aavid Thermalloy (Concord) and added 603 Manufacturing via portfolio company Trexon. Berkshire Partners and Court Square Capital backed Thrive's 2025 acquisition of NH-based Secured Network Services. Great River Capital has driven Salem-based Micro-Precision Technologies' roll-up. Roughly 35+ NH transactions tracked by PrivSource since 2024 reflect this corridor strategy.
CHIPS Act and Defense-Tech M&A Reshaping the Nashua Ecosystem
Federal industrial policy is reshaping NH defense M&A. The $35.5M CHIPS Act award to BAE Systems' Nashua Microelectronics Center created a halo for NH RF/microwave and FPGA design firms. Anduril Industries acquired American Infrared Solutions (AIRS) in 2025 to bring cooled-IR camera production in-house; ITT paid ~$475M for kSARIA (Sept 2024); Arcline's Quantic platform absorbed TRM Microwave; and Pacific Defense (HCI Equity/Emerald Lake) acquired Spear Research in Nashua. Buyers pay 9–13x EBITDA for sole-source DoD content.
Dartmouth Health and Out-of-State Systems Absorbing Rural Hospitals
With NH's Certificate of Need board eliminated in 2016, 22 of 26 acute-care hospitals have been absorbed into systems. Dartmouth Health (13,000+ employees, 8 member hospitals) added Valley Regional (July 2024), took over Hampstead Hospital under a $15.5M state contract (Feb 2025), and signed an LOI for Littleton Regional Healthcare (25 beds, 60,000 patients/year) in September 2025. Out-of-state platforms — HCA Healthcare, Mass General Brigham, and MaineHealth — continue squeezing the remaining independents, creating acquisition targets among profitable ancillaries.
Indy Pass Counter-Consolidation in Ski and Outdoor Tourism
While KSL Capital Partners raised a $3B continuation fund for Alterra in January 2025 (~12x EBITDA at ~$7B EV) and Vail Resorts continued operating four NH mountains, the most consequential NH deal was Entabeni Systems' (Indy Pass) ~$7.5M acquisition of Black Mountain in October 2024, generating 36,000 skier visits in year one with doubled snowmaking output. With Vail Resorts reporting a 2% decline in pre-season pass sales for 2024/25 — the first since the Epic Pass launched in 2008 — buyers are recalibrating toward independently operated NH ski/four-season assets.
Exit Preparation Timeline
A practical roadmap for New Hampshire business owners planning an exit.
- Document owner-operator compensation under RSA 77-A Rev 303.01 with job description, hours logged, and IRC §162(a)(1) comparables to defend the BPT compensation deduction — a key buyer normalization lever in NH due diligence.
- Review entity structure: with I&D repealed (TIR 2025-001), the historical preference for non-transferable LLC interests is moot; evaluate C-corp conversion if QSBS planning under §1202 (greater of $15M or 10× basis under post-OBBBA rules) is feasible and the 5-year clock has not yet started.
- Catalog all NH real property and identify "real estate holding company" structures under RSA 78-B, quantifying potential RETT exposure (1.5% of NH FMV) on a controlling-interest stock sale and evaluating PropCo/OpCo separation timing.
- For defense/aerospace targets, audit ITAR registration with State Dept. DDTC, EAR jurisdictional classification, CMMC 2.0 readiness assessment, and AS9100 Rev D / NADCAP / ISO 9001 certifications — each adds 1.0–2.0x EBITDA premium per Precision Firm 2026 benchmark data.
- Reconcile all BPT (Form BT-Summary), BET, M&R (RSA 78-A), and CST (RSA 82-A) filings via Granite Tax Connect (GTC); clear any audit exposures; confirm GTC account is current; resolve any I&D legacy issues from 2024 or earlier transitional years.
- Commission sell-side Quality of Earnings normalizing for owner comp (Rev 303.01), BPT/BET add-backs, M&R/CST liabilities, optional RSA 77-A:4 step-up election analysis, and NH R&D credit utilization (capped at $50,000 per taxpayer) — pre-empting buyer adjustments that compress EBITDA.
- Consider spinning real estate into a separate LLC with triple-net lease pre-sale to optimize EBITDA, isolate RETT exposure to one transaction, and give buyers asset-vs-stock optionality without triggering the controlling-interest RETT inadvertently.
- Reduce top-5 customer concentration below 25% (each 5% reduction adds ~0.25x EBITDA per Precision Firm benchmark); for defense companies, diversify prime-contractor relationships across BAE Nashua, Lockheed Sikorsky, GE Aerospace Hooksett, and L3Harris Londonderry programs over 12–24 months.
- Negotiate the RSA 78-B RETT 50/50 split (default per Rev 800, but negotiable), the optional RSA 77-A:4 step-up election (model both scenarios for buyer depreciation vs. seller phantom-income tradeoffs), and BPT successor liability indemnity with tax escrow funded at 1–2% of EV.
- Build NH-specific representations and warranties around RETT controlling-interest exposure, BPT reasonable-compensation defensibility under Rev 303.01, BET 10-year credit carryforward history, and M&R/CST registrations for hospitality and telecom/MSP targets.
- For defense targets, submit ITAR change-of-ownership notification to DDTC ≥60 days pre-close; assess foreign-buyer ineligibility absent TAA/CFIUS mitigation; pre-file CFIUS notice if target holds classified or controlled-technology work — delays of 60–120 days are routine for foreign-buyer processes.
- Leverage the Boston-area strategic and PE buyer pool — NH targets attract premium pricing from MA-based buyers seeking no-income-tax positioning for portfolio companies; model the after-tax proceeds differential between NH (0% state) vs. MA (9% + 4% millionaires surtax) explicitly in seller's CIM materials.
- Obtain DRA tax clearance certificates for BPT, BET, M&R, CST, and any I&D legacy residuals from 2024 — required for a clean asset purchase and to extinguish successor liability under RSA 78-B and NH common law.
- File CD-57-S (Seller) and CD-57-P (Purchaser) declarations and PA-34 inventory within 30 days of recording, verifying allocation between real estate (subject to RETT) and personalty/intangibles (not subject to RETT); a well-documented PPA directly reduces the taxable RETT base.
- Transfer M&R operator license (Form M&R-9), CST retailer registration, contractor licenses with OPLC, DDTC ITAR registration update, and EAR registrations to buyer; confirm Pease Development Authority leasehold consent if target occupies Tradeport space.
- NH residents retain 100% of after-federal proceeds — execute federal QSBS §1202 election where eligible (tiered 50/75/100% exclusions under OBBBA for stock issued after July 4, 2025), §1045 rollovers into new QSBS, and CRT/DAF planning for excess proceeds; no NH-level overlay erodes these benefits.
Why New Hampshire Business Owners Choose Ad Astra
Local market knowledge and national buyer networks — the combination that drives premium outcomes for New Hampshire business owners.
Schedule a ConsultationBoston-Metro Buyer Access with the NH Tax Edge
Southern NH (Nashua, Salem, Manchester, Portsmouth) sits within Boston's 50-mile strategic-buyer radius. We translate that adjacency into competitive tension: Greater Boston PE platforms and strategics routinely pay NH-target premiums because NH's no-income-tax status is itself a portfolio-company asset for employee retention, executive relocation, and HoldCo domiciling. Our buyer list cross-references NHADC membership with Boston-corridor sponsors including Audax, Berkshire Partners, Charlesbank, Gemini, and Riverside.
BPT/BET/RETT Navigation and I&D Repeal Structuring
With the Interest & Dividends Tax fully repealed effective January 1, 2025 (TIR 2025-001), NH joined the zero-individual-income-tax cohort (#3 on the Tax Foundation's 2026 State Tax Competitiveness Index). Our team handles the full NH-specific tax matrix: optional RSA 77-A:4 step-up election modeling; §1202 federal QSBS planning with NH zero-state-tax stacking; RETT controlling-interest planning (1.5% combined, RSA 78-B) and PropCo/OpCo carve-out execution; BPT reasonable-compensation defensibility under Rev 303.01; and DRA tax clearance procurement for BPT, BET, M&R, and CST accounts.
Defense and Aerospace Prime Contractor Relationships
Direct execution experience with deals involving BAE Systems Nashua flowdown suppliers, GE Aerospace Hooksett tier-2 vendors, L3Harris Londonderry partners, Sig Sauer (Newington) suppliers, and Hitchiner-style investment-casting platforms. We coordinate ITAR DDTC notifications (≥60 days pre-close), EAR jurisdictional analyses, CFIUS pre-filings, CMMC 2.0 readiness, and AS9100/NADCAP audit gap closure, with a buyer Rolodex spanning Heico, TransDigm, Moog, Curtiss-Wright, Howmet, AE Industrial Partners, Arlington Capital, and Liberty Hall Capital.
Silver-Tsunami Succession Pipeline Expertise
NH is the 2nd-oldest state in the U.S. by median age (43.6 years), a net exporter of younger talent, and sits on a deep pipeline of baby-boomer-owned LMM businesses approaching forced exits in 2026–2028. We specialize in succession planning for defense-subcontractor founders, multi-generational precision-manufacturing families, and services-business owners who built enterprises serving the Boston MSA from a NH domicile. Our process combines estate-freeze techniques under the NH zero-estate-tax advantage with competitive auction structures that consistently surface Boston-area buyers unwilling to wait for off-market access.
New Hampshire M&A Activity Highlights
ITT Inc. acquired kSARIA for ~$475 million (announced Aug 2024, closed Sept 2024) from Behrman Capital, adding ~1,000 employees across six North American sites and expanding ITT's Connect & Control Technologies fiber-optic and electrical interconnect capabilities serving NH defense customers.
Dartmouth Health signed a letter of intent in September 2025 to acquire Littleton Regional Healthcare (25-bed critical-access hospital, ~60,000 patients annually), following its July 2024 acquisition of Valley Regional Hospital and February 2025 launch of a $15.5M, 7-year operating partnership for Hampstead Hospital.
Anduril Industries acquired American Infrared Solutions (AIRS) in 2025, integrating the NH-based cooled-IR camera manufacturer into Anduril's sensing product families; Arcline Investment Management's Quantic platform separately added NH-based TRM Microwave; and Pacific Defense (HCI Equity/Emerald Lake) acquired Nashua's Spear Research.
Entabeni Systems (Indy Pass owner Erik Mogensen) acquired Black Mountain in October 2024 for approximately $7.5 million, doubled snowmaking output, added 28,000 feet of new snow-pipe and 200 snow guns, and recorded ~36,000 skier visits in the first season.
Micro-Precision Technologies (Great River Capital Partners) acquired Stellar Manufacturing in Salem, NH in October 2025; Audax-backed Trexon acquired 603 Manufacturing (RF/microwave cable assemblies); and Hilb Group (Carlyle portfolio) completed an early-2025 NH P&C agency add-on — collectively representing 35+ NH transactions tracked between 2024 and early 2026.
Tax & Deal Structure in New Hampshire
New Hampshire is the most seller-favorable state in New England and one of the top three in the United States. With the Interest & Dividends Tax fully repealed effective January 1, 2025, individual sellers face zero state tax on capital gains, wages, distributions, and investment income — leaving only the federal 23.8% LTCG+NIIT as the relevant rate. The Tax Foundation's 2026 State Tax Competitiveness Index ranks NH #3 nationally. The key frictions are the entity-level Business Profits Tax (7.5% BPT + 0.55% BET) and the distinctive RETT controlling-interest rule (1.5% combined on NH real estate FMV), both of which reward careful pre-close structuring.
Zero Individual Capital Gains Tax (Post-I&D Repeal)
FavorableWith the Interest & Dividends Tax repealed effective January 1, 2025 (TIR 2025-001), NH individual sellers pay 0% state tax on capital gains, sale proceeds, and investment income. Federal LTCG + NIIT (23.8%) is the only rate applicable to stock-sale proceeds. This is the most decisive structural differentiator in the region — compared to MA (9% flat + 4% surtax above $1M), ME (7.15% ordinary), and VT (8.75% top rate), NH sellers of a $30M business retain approximately $1.8M–$3.9M more in after-tax proceeds.
Business Profits Tax (BPT) and Business Enterprise Tax (BET)
NeutralThe BPT is 7.5% (RSA 77-A) for taxable periods ending on or after Dec 31, 2023, with a 2025 filing threshold of >$109,000 gross business income. Single-sales-factor apportionment and mandatory unitary combined reporting apply; bonus depreciation under §168(k) is disallowed and §179 is capped at $500,000. The BET is 0.55% on compensation + interest + dividends paid (RSA 77-E) with a 2025 threshold of >$298,000; BET is creditable against BPT with a 10-year carryforward — making careful purchase-price allocation between personal goodwill and enterprise goodwill a meaningful planning lever.
Real Estate Transfer Tax — Controlling-Interest Trap
UnfavorableRSA 78-B imposes RETT of $0.75/$100 on each side (1.5% combined) on direct deeds AND on transfers of controlling interests in real-estate-holding entities at NH real estate FMV. A 50%+ interest transfer in an LLC holding a $10M Nashua facility triggers ~$150,000 of RETT that a pure-equity stock-deal buyer expects to avoid. Pre-close PropCo/OpCo separation — filing RETT once at FMV, then leasing back — isolates the exposure, preserves stock-sale flexibility for the operating business, and avoids the buyer's surprise post-close liability under Forms CD-57 and PA-34.
QSBS §1202 Conformity — Full Effective Benefit
FavorableNH delivers 100% effective QSBS conformity because there is no individual capital gains tax. A founder selling QSBS-qualified C-corp stock pays $0 NH tax regardless of §1202 mechanics. Post-July 4, 2025 OBBBA enhancements — tiered 50/75/100% exclusions at 3/4/5 years, greater of $15M or 10× basis cap, $75M gross-asset ceiling — are captured with no state-level erosion. For NH-domiciled QSBS founders, the combined federal + state benefit is the maximum available in any income-tax jurisdiction in the United States.
Estate, Inheritance, and Gift Taxes — None
FavorableNH has no state estate tax, no inheritance tax, no gift tax, and no GST tax. The Legacy & Succession Tax (RSA 86) and Nonresident Personal Property Transfer Tax (RSA 89) were both repealed effective January 1, 2003. NH residents capture the full federal $13.99M (2025) / $15M (2026) exemption — made permanent and inflation-indexed by OBBBA — with no state-level overlay. Compared to Vermont's $5M flat estate exemption (no portability, 16% rate) and Maine's $7.16M exemption (no portability, 12% top rate), NH business owners retain significantly more intergenerational wealth on estate-tax-driven partial exits or installment sales.
Meals & Rentals Tax and Communications Services Tax
NeutralThe Meals & Rentals Tax (RSA 78-A) is 8.5%, and the Communications Services Tax (RSA 82-A) is 7% — both require successor-licensing coordination for hospitality, restaurant, short-term rental, and telecom/MSP M&A targets. Failure to transfer M&R operator licenses and CST registrations at closing creates successor liability that can surface in post-close audits. NH DRA tax clearance certificates covering M&R and CST are a standard closing deliverable for consumer-facing and telecom-adjacent targets.

$35M-$60M (24-36 months)The Challenge
Founder-CEO was sole holder of customer relationships at BAE Systems and Lockheed Martin program managers; chief programmer held tribal knowledge on legacy 5-axis CNC fixturing. NH-specific overlays: ITAR change-of-ownership notification to DDTC required ≥60 days pre-close with foreign-buyer ineligibility absent CFIUS mitigation; BPT compensation deduction defense for the owner's $1.2M historical reasonable comp under Rev 303.01; and RETT controlling-interest exposure on the owned 85,000-sq-ft Nashua facility (~$11M FMV) requiring a PropCo/OpCo carve-out to avoid $165K of inadvertent combined RETT.
The Process
- 1Pre-marketing positioning: sell-side QoE, AS9100 Rev D / NADCAP refresh, CMMC Level 2 self-assessment, PropCo/OpCo split with RETT filed once at FMV on the facility, backlog normalization, and key-person retention agreements signed for the chief programmer and two senior program managers.
- 2Buyer outreach under ITAR/EAR-gated CIM to strategics (Heico, TransDigm, Moog, Curtiss-Wright, Howmet, Senior plc) and upper-MM PE platforms (Arlington Capital, AE Industrial Partners, Liberty Hall Capital, Bridges Industries, Industrial Growth Partners).
- 3LOI and diligence with base price plus earnout (10–20% of consideration tied to 24-month backlog conversion), R&W insurance, and tax diligence focusing on BPT optional step-up election (RSA 77-A:4), RETT exposure on PropCo, ITAR registration validity, and BAE/Lockheed contract assignability.
- 4DDTC change-of-ownership notification filed 65 days pre-close; DRA tax clearance obtained for BPT, BET, and M&R; RETT filings for PropCo executed at FMV; definitive agreement closed with 12-month key-person stay bonuses converting to rollover equity.

Key Lessons
- Certifications are the multiple — AS9100 Rev D + NADCAP + ITAR + Tier-1 prime-supplier codes added 1.0–2.0x EBITDA versus generic precision shops; the certification stack is the single highest-ROI pre-sale investment available to NH defense manufacturers.
- Customer concentration destroys optionality — each 5% reduction in top-customer concentration adds ~0.25x EBITDA (Precision Firm 2026 benchmark); deliberate diversification across BAE Nashua, GE Aerospace Hooksett, and L3Harris Londonderry programs materially expands the buyer universe and eliminates concentration discounts.
- Plan the RETT controlling-interest trap early — pre-close PropCo/OpCo separation pays RETT once at FMV under RSA 78-B, then leases back, preserving stock-sale flexibility for the operating company and isolating real-estate risk; sellers benefit from NH's zero state capital gains (post-I&D repeal), a federal-only outcome Boston-based buyers cannot access for their own portfolios.
