Introduction

The South Carolina Ports Authority (SCPA) operates one of the deepest-water container ports on the U.S. East Coast. Serving the Port of Charleston and inland ports in Greer and Dillon, the Authority has emerged as a gateway handling approximately 2.5 million TEUs annually (CY 2024), with notable import-export cargo balance and high berth productivity.

FY 2024 operating revenue declined 9.9% to $404.0 million as cargo volumes normalized from pandemic-era highs; the Authority simultaneously managed a 14+ month operational disruption related to a labor dispute at the Leatherman Terminal (reopened Sep 2024) and continued capital investment totaling $1.05 billion (FY 2016–2020) in terminal capacity and port infrastructure. With $998.0 million in outstanding senior revenue bonds and $373.9 million in direct borrowings, SCPA operates under a net revenue pledge structure and carries stable credit ratings (S&P A+, Moody's A1).

This profile covers SCPA's financial performance, bond structure, capital program, and credit characteristics — a reference for investors evaluating East Coast port revenue bonds or comparative port credit risk.

Operational Performance

The Port of Charleston ranks approximately 8th largest among U.S. container ports by throughput, moving approximately 2.5 million TEUs (twenty-foot equivalent units) in CY 2024. The Authority benefits from an import-export cargo balance that reduces empty container repositioning costs, compared to East Coast peers with higher directional imbalances.

Metric	Value
Container Throughput (TEUs)	~2.5 million (CY 2024)
U.S. Ranking	~8th largest by volume
Channel Depth	52 feet (among the deepest East Coast, neo-Panamax accessible)
Cargo Balance	Import-export balance (reduces repositioning costs)
Terminal Capacity (full build-out)	~4–5 million TEU/year at full build-out (Leatherman Phase 1+2: 2.4M TEU; Wando Welch: ~1.5M TEU; North Charleston: ~0.5M TEU)

Moody's has characterized the Authority as having "unusually high productivity" — a direct indicator of berth utilization and operational efficiency relative to peer ports (Moody's, December 2023 rating reaffirmation).

Financial Summary

Item	FY 2024	FY 2023	YoY Change
Total Operating Revenue	$404.0M	$448.5M	-9.9%
SMART Chassis Pool Revenue	$42.6M	$38.9M	+9.7%
Capital Assets	$2.2B	$2.0B	+10.2%

FY 2024 Performance: Total operating revenue of $404.0 million represents a 9.9% decline from FY 2023 ($448.5 million), as containerized cargo volumes normalized from the pandemic-era surge. However, the SMART Chassis Pool — the Authority's owned fleet of over 1,000 chassis units — generated $42.6 million and increased 9.7% year-over-year, representing 10.5% of total operating revenue. Capital assets grew 10.2% to $2.2 billion, reflecting continued investment in terminal infrastructure.

Revenue Drivers: Primary revenue sources include container tariffs (wharfage and handling charges on containerized cargo), terminal operating leases (equipment and facility use), the SMART Chassis Pool, breakbulk and general cargo services, and warehouse/storage operations.

Hugh K. Leatherman Terminal — Capital Investment & Operational Recovery

The Hugh K. Leatherman Terminal represents the Authority's largest capital project to date — an investment in Charleston Harbor's container capacity and competitive standing. Originally completed with a $422 million investment funded by 2019A/2019B revenue bonds, the terminal was closed for 14+ months (mid-2023 through late September 2024) due to an unresolved labor dispute with the International Longshoremen's Association (ILA). This extended closure interrupted 700,000 TEU/year of capacity for 14+ months and is a credit risk factor relevant to bond investors.

Feature	Details
Phase 1 Capital Cost	~$422 million
Primary Berth Length	1,400 feet
Ship-to-Shore (STS) Cranes	5 units (169-foot lift, 228-foot outreach)
Rubber-Tired Gantry (RTG) Cranes	25 hybrid units
Phase 1 Capacity	700,000 TEU/year
Full Build-Out Capacity (Phases 1+2)	2.4 million TEU/year
Reopening Date	September 25, 2024
Labor Closure Duration	14+ months (mid-2023 through Sep 2024) — ILA dispute

Phase 2 Status: The second berth for full build-out capacity is currently in bidding process, requiring additional bonding authority and capital funding. This ongoing capital requirement may require additional debt issuance, which would affect coverage and leverage metrics.

Bond Structure & Debt Outstanding

Debt Component	Amount
Outstanding Senior Revenue Bonds (as of Jun 30, 2024)	$998.0M
Direct Borrowings Outstanding	$373.9M
Total Debt Outstanding	~$1.372 billion

Revenue Pledge: All outstanding revenue bonds are secured by a pledge of net revenues — operating revenues minus operating and maintenance expenses. Facilities pledged include Wando Welch Terminal, Hugh K. Leatherman Terminal, North Charleston Terminal, Greyfield Terminal, and inland port facilities at Greer and Dillon.

Rate Covenant & Debt Service Reserve Fund (DSRF): The bond indenture requires SCPA to set tariff rates and charges sufficient to maintain net revenues at or above the legally required DSCR (debt service coverage ratio) covenant level — the structural mechanism that obligates the Authority to raise rates if revenues fall short of required coverage. DSCR measures annual net revenues divided by annual debt service; investors should reference the applicable bond indenture for the specific covenant threshold. A Debt Service Reserve Fund (DSRF), typically funded at maximum annual debt service, provides a secondary liquidity cushion and additional bondholder protection. FY 2024 revenue of $404.0 million (net of O&M) relative to approximately $1.37 billion in total outstanding debt is the primary framework for evaluating current coverage adequacy.

Credit Ratings:

• S&P: A+ (Stable outlook)
• Moody's: A1 (Stable; reaffirmed December 2023)
• Fitch: Does not rate SCPA revenue bonds

Major Bond Series: 2019A (Non-AMT), 2019B (AMT), 2019C (Refunding of 2015), 2019D, 2018, 2015. The 2019 issuance totaled $547 million — the largest in Port history — and financed Leatherman Phase 1 and the Port Access Road.

Capital Program & Infrastructure Investment

SCPA operates under a multi-decade capital plan funded through revenue bonds, state appropriations, and federal grants. Two signature projects define the Authority's strategic positioning:

1. Charleston Harbor Deepening (~$580M total)

Successfully completed at 52 feet — among the deepest harbors on the U.S. East Coast, deeper than Baltimore (50 ft) though Norfolk leads the region at 55 ft. This depth accommodates neo-Panamax container vessels. Funding sources: State appropriation of $300 million (set aside 2012), Federal funding totaling approximately $138 million (2019) plus $25 million FY 2024 and $21.28 million FY 2025.

2. Hugh K. Leatherman Terminal (~$422M Phase 1 completed; Phase 2 in bidding)

As detailed above, Phase 1 provides 700,000 TEU/year capacity with 5 ship-to-shore cranes (169-ft lift) and 25 hybrid RTG cranes. Phase 2, currently in procurement, will add a second berth and bring total capacity to 2.4 million TEU/year. Historical investment FY 2016–2020 totaled $1.05 billion. The State of South Carolina has committed approximately $800 million to ongoing infrastructure — a credit support factor noted by rating agencies.

Credit Analysis: Strengths & Risks

Credit Strengths:

1. Deep-Water Harbor Advantage: At 52 feet, Charleston Harbor is among the deepest on the U.S. East Coast — deeper than Baltimore (50 ft), though Norfolk leads at 55 ft. This depth accommodates neo-Panamax vessels (up to 18,000+ TEU capacity), a prerequisite for major Trans-Atlantic shipping routes.
2. Cargo Balance: Import-export equilibrium reduces empty container repositioning costs relative to East Coast peers with more directionally imbalanced trade flows.
3. Geographic Reach: Proximity to major markets (Charlotte, Raleigh, Atlanta, Greenville) within a 200-mile radius supports continued cargo demand.
4. Productivity: Moody's (December 2023) recognizes "unusually high productivity" — a direct measure of berth utilization and labor productivity relative to peer ports.
5. Self-Sustaining Model: SCPA receives no state operating appropriations — operations are funded entirely by tariff revenue — reducing exposure to state budget cycles.
6. Revenue Diversification: SMART Chassis Pool ($42.6M, +9.7% YoY) provides non-tariff revenue streams reducing exposure to container volume volatility.
7. Investment-Grade Ratings: S&P A+ (Stable) and Moody's A1 (Stable, Dec 2023) — upper-medium grade, equivalent to a single-notch below the AA tier.

Credit Risks:

1. Cargo Volume Volatility: FY 2024 revenue declined 9.9% as cargo volumes corrected from pandemic-era highs. Further recession or trade disruption poses downside risk to net revenues and debt service coverage.
2. $1.37 Billion Debt Load: ~$1.37 billion outstanding with ongoing capital requirements for Leatherman Phase 2 may necessitate additional debt issuance, pressuring leverage and coverage metrics.
3. Labor Relations Risk: The 14+ month closure of Leatherman Terminal (mid-2023 through September 2024) due to an ILA labor dispute demonstrates that labor actions can interrupt 700,000 TEU/year of capacity. Future disputes carry similar risk.
4. Competitive Pressure: Georgia Ports (Savannah) is actively expanding capacity; Virginia Port (Norfolk) is enhancing channel deepening and efficiency. Charleston's market share may face pressure.
5. Capital Requirements: Leatherman Phase 2 and ongoing infrastructure maintenance require additional borrowing, which may pressure coverage ratios if cargo volumes decline.
6. Economic Sensitivity: Container traffic is sensitive to industrial production, international trade flows, and consumer demand. SCPA's FY 2024 revenue declined 9.9% from its FY 2023 peak as trade volumes corrected; tariff policy changes or recession could similarly reduce throughput and tariff revenues.
