MGIC Investment (MTG) Q4 2025 earnings review
Volume Grows, But Profits Slip on Normalizing Credit Costs
MGIC closed 2025 with mixed results. While New Insurance Written (NIW) accelerated to $17.1B (+7.5% YoY), profitability came under pressure. Net Income fell 8% YoY to $169.3M, primarily driven by a sharp normalization in credit costs—the loss ratio tripled to 13.2% from 3.6% a year ago. Despite the earnings headwinds, the capital return engine remains robust, with $189M in Q4 buybacks and a significant $400M dividend paid to the holding company. The narrative is shifting from 'pristine credit' to 'normalizing credit,' which will test margin resilience in FY26.
🐂 Bull Case
New Insurance Written (NIW) hit $17.1B, the highest level of FY25 and up 7.5% YoY. Insurance In Force (IIF) crossed the $303B threshold, ensuring a stable base for future premiums.
MTG repurchased 6.8M shares ($189M) in Q4 and continued into Q1 2026 with another 2.7M shares. The $400M upstream dividend to the holding company signals ample liquidity to sustain shareholder returns.
🐻 Bear Case
Incurred losses jumped to $31.2M from just $8.7M a year ago. The loss ratio of 13.2% is still manageable but represents a sharp break from the <5% levels seen throughout FY24 and early FY25.
Net premium yield slid to 31.2 bps, down from 32.9 bps in 24Q4 and 32.3 bps in 25Q3. Declining yields combined with rising loss ratios create a double squeeze on operating margins.
⚖️ Verdict: ⚪
Neutral. The volume growth is encouraging, suggesting MGIC is winning business in a competitive market. However, the triple-digit percentage increase in incurred losses and concurrent dip in Net Income warrant caution until the trajectory of the 2026 loss ratio stabilizes.
Key Themes
Incurred Losses Spike
The era of near-zero credit costs appears to be ending. Net losses incurred rose to $31.2M in Q4, significantly higher than the $10.9M in Q3 and $8.7M in the prior year. While management previously guided for normalization, the acceleration to a 13.2% loss ratio (vs 4.5% last quarter) is abrupt. This likely reflects the aging of the 2022-2023 vintage books entering peak loss emergence periods.
Capital Return Machine
MGIC continues to aggressively shrink its share count. The company repurchased 6.8 million shares for $189.1M in Q4 and has already bought another 2.7 million shares in Jan 2026. This consistent bid provides a floor for EPS despite the net income headwinds. Tangible Book Value per share grew 9.5% YoY to $24.08.
New Business Acceleration
Accelerating. Q4 New Insurance Written (NIW) of $17.1B represents an acceleration from $16.5B in Q3 and $15.9B in 24Q4. This suggests MGIC is effectively navigating the competitive landscape and finding opportunities despite a challenging housing affordability backdrop.
Premium Yield Compression
Decelerating. Net premium yield fell to 31.2 bps in Q4, down from 32.3 bps in Q3 and 32.9 bps a year ago. Continued compression here limits the revenue leverage from IIF growth. This trend suggests either competitive pricing pressure or increased reinsurance ceding costs weighing on net yields.
Reinsurance Activity
MGIC remains active in managing capital via reinsurance. In Q4, they executed a 40% quota share for 2027 NIW. In Jan 2026, they executed a $324M excess-of-loss deal. While this protects the balance sheet against tail events, the cost of these programs is partially responsible for the net premium yield compression noted above.
Other KPIs
Stable/Growth. Up from $300.8B in Q3 and $295.4B in 24Q4. Crossing the $300B mark is a psychological win, but growth remains slow (~2.6% YoY) due to the large existing base and reduced prepayments.
Deteriorating slightly. Up from 2.32% in Q3 and 2.40% in 24Q4. The inventory of delinquent loans rose to 27,072 from 25,747 in Q3, confirming the normalization thesis.
Improving. Down from 21.1% in Q3 and 20.8% in 24Q4. This indicates strong cost discipline is partially offsetting the rise in loss ratios.
Guidance
Stable. The company has already executed $73.2M in buybacks in Jan 2026 and declared a $0.15 dividend payable in March. There is no explicit change in pace, implying the 'elevated payout' strategy continues despite earnings compression.
Key Questions
Loss Ratio Trajectory
Losses incurred tripled YoY to $31.2M. Is this 13.2% loss ratio the new run-rate for 2026, or did Q4 include specific one-time reserve strengthenings?
Net Premium Yield Floor
Net premium yield compressed 110 bps sequentially to 31.2 bps. How much of this is driven by the new reinsurance layers versus competitive pricing on new business, and where does this stabilize?
Buyback Appetite vs. Credit Costs
With credit costs normalizing and Net Income declining sequentially, does the Board plan to maintain the same pace of share repurchases ($180M+ per quarter) throughout 2026?
NIW Acceleration Drivers
NIW accelerated to $17.1B in Q4. Was this driven by specific market share gains, or a temporary surge in purchase activity in your specific geographies?
