Impac Mortgage Holdings, Inc. Announces Second Quarter 2017 Results

Irvine, CA, August 8, 2017 — Impac Mortgage Holdings, Inc. (NYSE American: IMH) announces the financial results for the quarter ended June 30, 2017.

For the second quarter of 2017, the Company reported GAAP net earnings of $6.4 million, or $0.32 per diluted common share, and Adjusted Operating (Loss) Income (as defined below) of $(174) thousand, or $(0.01) per diluted common share, as compared to GAAP net earnings of $12.3 million, or $0.92 per diluted common share, and Adjusted Operating Income of $18.5 million, or $1.33 per diluted common share for the second quarter of 2016.

Operating income, excluding the changes in contingent consideration (“Adjusted Operating (Loss) Income”), is considered a non-GAAP financial measurement; see the discussion and reconciliation of non-GAAP financial measures below.

Net earnings include certain fair value adjustments, which are non-cash items and are not related to current operating results.  Although we are required by GAAP to record these fair value adjustments, management believes Adjusted Operating (Loss) Income as defined above is more useful to discuss the ongoing and future operations of the Company, shown in the table below:

Adjusted Operating (Loss) Income decreased to a loss of $(174) thousand, or $(0.01) per diluted common share, for the second quarter of 2017 as compared to $18.5 million, or $1.33 per diluted common share, in the second quarter of 2016.  The decrease in operating income was primarily due to a decrease in gain on sale of loans of $42.0 million resulting from a 45% decrease in total originations volume (as discussed below).  Additionally, the decrease was magnified due to a higher concentration of volume in the third party origination channel, as well as margin compression due to increased competition caused by less available volume.  While we have increased the volume of NonQM loans (discussed below), we have not increased the volume to the level desired, which also contributed to less than expected margins in the second quarter.  As a result, gain on sale margins decreased by 38 basis points (“bps”) to 205 bps in the second quarter of 2017, as compared to 243 basis points in the second quarter of 2016.

Servicing Portfolio Data

(in millions)

As a result of the retention of servicing starting in 2016, the unpaid principal balance (“UPB”) of the Company’s mortgage servicing portfolio increased 121% to $14.7 billion as of June 30, 2017 from June 30, 2016.  The servicing portfolio generated net servicing fees of $7.8 million in the second quarter of 2017, a 177% increase over the net servicing fees of $2.8 million in the second quarter of 2016.  Additionally, delinquencies within the servicing portfolio remain low at 0.34% for 60+ delinquencies as of June 30, 2017.

The loss on mortgage servicing rights (“MSR”) in the second quarter was primarily due to mark-to-market (“MTM”) loss and changes associated with payoffs in the portfolio related to the decrease in prevailing mortgage rates in the second quarter.

Origination Data

(in millions)

During the second quarter of 2017, total originations decreased 45% to $1.8 billion as compared to $3.2 billion in the second quarter of 2016.  This decrease was a result of lower refinance volume, due to a higher interest rate environment, as compared to the second quarter of 2016.

In the second quarter of 2017, NonQM and government-insured originations represented approximately 40% of total originations, as compared to just 16% of total originations in the second quarter of 2016.

During the second quarter of 2017, the origination volume of NonQM loans increased to $232.5 million, as compared to $184.3 million in the first quarter of 2017 and $289.6 million of NonQM production for all of 2016.  In the second quarter of 2017, the retail channel accounted for 36% of NonQM originations while the wholesale and correspondent channels accounted for 64% of NonQM production.

Additionally, in the second quarter of 2017, the Company’s government-insured loan production increased to $481.8 million, as compared to $448.5 million in the second quarter of 2016.  NonQM and government-insured mortgages are typically a higher margin product for the Company.

As of June 30, 2017, our locked pipeline, which represents mortgages we expect to close in the near future, was $643.4 million, as compared to $553.1 million at March 31, 2017.  As of June 30, 2017, our NonQM pipeline had increased to approximately $260.7 million as compared to $201.8 million at March 31, 2017.

Mr. Joseph Tomkinson, Chairman and CEO of Impac Mortgage Holdings, Inc., commented, “As we continue to grow our NonQM production, our NonQM pipeline is now trending towards the origination levels we had hoped for.  Additionally, as our servicing portfolio continues to grow, the servicing fees generated are finally becoming a significant and consistent revenue stream.  We expect that these servicing fees will only continue to grow and become even more impactful as our servicing portfolio grows.”
