Sales activities continue at record levels… Increase in sales activity from prior year is attributable to: 1) increased availability of advisors, 2) higher level of sales outreach, 3) greater number of marketing initiatives and 4) limited in-person events leading to a reduction in sales travel time Note: Sales activity includes all engagement points (meetings, both virtual and in person, substantive calls) Leads are defined as advisors who have not been converted to the prospect stage yet. Contacts include prospects, NPAs and existing advisors. August sales activity is based on real data through August 15th, and then run-rated for the remainder of the month. AssetMark is providing additional data to help provide context during these uncertain times, and does not intent to create a new obligation for future disclosure. Sales activity is not an indication of future production.

Commentary: Improved proposal trend reflect COVID adjustment & market sentiment The proposal activity is a good leading indicator for advisor engagement on our platform. Generally, a subset of proposals will convert to submitted accounts in 60-90 days, although this time has been lengthened as a result of the pandemic. ...as proposal volumes begin to trend back to pre-COVID levels Note: August data is based on actual data through August 15th, and then run-rated for the remainder of the month.

As mentioned during our 2Q20 earnings call, net flows as a % of Beginning Platform Assets are expected to be 8% to 10% for FY2020 Monthly net flows during the pandemic (April-July) have averaged $307 million per month. To achieve the low end of the guidance, net flows would need to average $375 million per month from August through December. To achieve the high end of the guidance, flows would need to average $625 million per month over the same time period. In 2021, barring any dramatic changes in the macro environment, we are hopeful about achieving our previous target of 10%+. 1 Estimates for illustrative purposes to show the monthly averages required to hit low and high end of 8-10% guidance range. 2 Net flows through August 25th. This monthly data is being provided on a supplemental basis and should not be taken as a substitute for the August AMK report, to be released in mid-September.

Net yield trend analysis (2Q19-2Q20) Net Yield Commentary Net spread yield lower as a result of a lower interest rate environment causing AssetMark to earn less revenue on the cash held at ATC. 2Q action to transition all 3rd party retail mutual funds to institutional class will cause a decline in asset-based fees by ~2 bps starting in 3Q20. Looking ahead, continue to expect a regular decline in asset-based fee yield of 1 bp per year as a result of mix-shift. Note: Total may not add up due to rounding.

Adjusted EBITDA reconciliation – quarter ended June 30, 2020 (1)“Share-based compensation” represents granted share-based compensation in the form of Class C Common Units (which are incentive units) of AssetMark Holdings LLC, our former parent company, and RSA, restricted stock unit and stock option grants by us to certain of our directors and employees. Although this expense occurred in each measurement period, we have added the expense back in our calculation of adjusted EBITDA because of its noncash impact. (2)“IPO readiness” includes professional fees related to our preparation for becoming a public company. These expenses primarily include services for financial and human resources systems implementation, executive compensation assessments and other consulting services. These expenses are nonrecurring as they are limited to our public-company readiness preparation and do not include ongoing public-company compliance costs. (3)“Reorganization and integration costs” includes costs related to our functional reorganization within our Operations, Technology and Retirement functions as well as duplicate costs related to the outsourcing of back-office operations functions. While we have incurred such expenses in all periods measured, these expenses serve varied reorganization and integration initiatives, each of which is non-recurring. We do not consider these expenses to be part of our core operations. (4)“Acquisition expenses” includes employee severance, transition and retention expenses, duplicative general and administrative expenses and other professional fees related to acquisitions. (5)“Business continuity plan” includes incremental compensation and other costs that are directly related to operations while transitioning to a remote workforce and other costs due to the COVID-19 pandemic.
