ARMOUR Residential REIT spent the second quarter of 2026 quietly executing the playbook that defines externally-managed mortgage REITs in a steepening curve: lever up the Agency book, finance it through the affiliated repo desk, and let the duration hedge carry the P&L through mark-to-market noise. The result is a headline print that looks almost too clean for an mREIT - a Q2 swing from a substantial year-ago loss to a meaningful current-quarter net income, a basic earnings per share that flipped by a wide margin, and a book value that finished the first half up by a clear double-digit percentage against year-end. The total portfolio crossed the twenty-billion-dollar line at market value, dominated by Agency MBS with a small TBA overlay, and the book now earns a double-digit dividend yield at the prevailing share price. The trade is not subtle. ARMOUR is a yield instrument that compounds book value when the curve cooperates and bleeds book value when it does not, and the entire structure is tethered to one counterparty relationship that the market has spent the better part of two years learning to underwrite.

The mechanics under the headline matter as much as the headline itself. Net interest income for the quarter more than doubled year over year on both the larger asset base and the wider asset-and-liability spread as the policy rate held steady while longer-dated MBS yields remained range-bound. The derivative book swung from a sizable year-ago loss to a comparable current-quarter gain, an almost perfect mirror that reminds readers the GAAP P&L of an mREIT is dominated by mark-to-market on the hedge book rather than by realized spread. Total expenses after the management-fee waiver held essentially flat, and the external manager - ARMOUR Capital Management - elected to waive a portion of fees in the year-ago quarter but waived nothing in the current quarter, a change worth a paragraph later in this report. With the preferred dividend deducted, net income available to common shareholders was a meaningful positive, and the basic per-share figure cleared the run-rate dividend by a wide margin.

The story underneath the spread is BUCKLER Securities LLC. BUCKLER is the affiliated broker-dealer that provides close to half of ARMOUR's repo financing by principal, with a remaining term that is modestly longer than the unrelated counterparty book. The related-party repo balance grew in the first half of 2026 by a meaningful dollar amount, an expansion that mirrors the asset growth on the books. ARMOUR owns a low-double-digit equity interest in BUCKLER, and BUCKLER is the largest repo counterparty in the financing stack. The investment is not immaterial - it is the only meaningful non-securities holding on a balance sheet otherwise composed of Agency MBS, U.S. Treasuries, and derivatives - and the related-party concentration is the single most important risk variable in the equity story. We read the BUCKLER relationship as both an advantage (durable repo capacity when peer mREITs were tested in past periods of market stress) and a permanent discount factor that the market applies to ARMOUR's book value multiple.
