President’s Comments

“We are extremely pleased with our third quarter and nine-month financial results which exhibited solid core earnings combined with strong loan and deposit growth despite continued economic uncertainty,” said Joseph D. Roberto, Chairman,

President & Chief Executive Officer of PCSB Financial Corporation. “Annualized loan growth excluding PPP loans was 10.0% for the nine months and 13.6% for the current quarter. I am encouraged by the increased opportunities to originate quality loans within our strong market footprint. We believe we are well positioned to take advantage of the increase in market rates because of our currently elevated liquidity position, resulting from significant deposit growth, and expected loan and securities portfolio repricing opportunities. Of the $1.3 billion of loan balances, 15% are subject to daily or monthly repricing with another 4% scheduled to mature or re-price within the next 12 months; additionally, approximately 13% of our securities portfolio have adjustable rates, more than half of which are subject to re-pricing in the June quarter. I am proud of what our PCSB team has accomplished as we continue working to create sustainable value for our shareholders.”

Income Statement Summary

Net income for the current quarter was $3.5 million, which decreased $814,000 from the linked quarter and $118,000 from the prior year quarter. The change from the linked quarter is primarily due to a $541,000 decrease in net interest income, a $272,000 decrease in noninterest income and increases of $151,000 in noninterest expense and $22,000 in provision for loan losses, partially offset by a $172,000 decrease in income tax expense. The change from the prior year quarter is primarily due to increases of $1.2 million in provision for loan losses and $384,000 in noninterest expense, largely offset by increases of $1.1 million in net interest income and $331,000 in noninterest income, and a $35,000 decrease in income tax expense.

Net interest income was $12.7 million for the current quarter, a decrease of $541,000, or 4.1%, compared to the linked quarter and an increase of $1.1 million, or 9.3%, compared to the prior year quarter. The decrease compared to the linked quarter is primarily the result of a 17 basis point decrease in the tax equivalent net interest margin, partially offset by a $36.9 million, or 2.1%, increase in average interest-earning assets. The increase in net interest income compared to the prior year period is primarily the result of an 11 basis point increase in the tax equivalent net interest margin and a $99.6 million, or 5.7%, increase in average interest-earning assets.

The Company recognized PPP loan interest and origination fee income (net of costs) of $266,000 in the current quarter, compared to $332,000 in the linked quarter and $279,000 in the prior year quarter. Unearned origination fees (net of costs) on PPP loans totaled $117,000 as of March 31, 2022 and will be recognized in income over the remaining lives of the loans. The timing of such recognition is largely dependent on the timing of loan forgiveness, which the Company expects to be substantially complete by June 30, 2022.

The tax equivalent net interest margin was 2.80% for the current quarter, reflecting a decrease of 17 basis points compared to 2.97% in the linked quarter and an increase of 11 basis points compared to 2.69% in the prior year quarter. During the linked quarter, the Company recognized $555,000 of loan prepayment income. Adjusted net interest margin, which excludes the effects of loan prepayment income and PPP loan interest and fees, was 2.70% for the current quarter compared to 2.75% in the linked quarter and 2.61% in the prior year quarter. Compared to the prior year quarter, reductions in the cost of funds were partially offset by a decrease in adjusted asset yield, driven by lower market interest rates. Compared to the linked quarter, margin compression was the result of an increase in cash liquidity. Reconciliations of GAAP to non-GAAP financial measures are included at the end of this release.

Tax equivalent yield on interest-earning assets for the current quarter was 3.12%, decreases of 21 basis points from the linked quarter and 11 basis point from the prior year quarter. Excluding the effects of non-recurring PPP loan income and loan prepayment income, the tax equivalent yield on interest-earning assets for the current quarter was 3.03%, decreases of 8 basis points from the linked quarter and 10 basis points from the same quarter last year. The decrease in yield compared to the prior year quarter is a result of the loan and investment portfolios continuing to re-price downward due to lower market interest rates.

The cost of interest-bearing deposits was 0.37% for the current quarter, decreases of 2 basis points and 22 basis points from 0.39% and 0.59% in the linked quarter and prior year quarter, respectively. In response to lower market interest rates and increased liquidity levels, deposit rate reductions have been implemented throughout the last 2 years, the effects of which continue to be realized. As of quarter end, the weighted average cost of interest-bearing deposits was 0.35%. The cost of interest-bearing liabilities was 0.43% for the current quarter, decreases of 4 basis points from 0.47% in the linked quarter and 27 basis points from 0.70% in the prior year quarter. Over the next 12 months, the Company has $50.0 million of wholesale funding maturing, comprised of FHLB advances and brokered time deposits, with a weighted average cost of 2.03%.

The provision for loan losses was $286,000 for current quarter, compared to $264,000 for the linked quarter and a benefit for loan losses of $894,000 for the prior year quarter. Loans on COVID-19 related payment deferral totaled $3.6 million, or 0.28% of gross loans, as of March 31, 2022, compared to $27.3 million, or 2.21% of gross loans, as of June 30, 2021. Charge-offs, net of recoveries, were $4,000 for the current quarter compared to recoveries, net of charge-offs, of $6,000 for the linked quarter and $82,000 for the prior year quarter. Non-performing loans as a percent of total loans receivable (excluding PPP loans) was 0.61% as of March 31, 2022, an increase from 0.48% as of June 30, 2021.

Noninterest income of $923,000 for the current quarter decreased $272,000 compared to the linked quarter and increased $331,000 compared to the prior year quarter. The decrease compared to the linked quarter was primarily due to decreases of $548,000 in gain on the sale of premises, $32,000 in gains on the sale of loans and $25,000 in all other noninterest income, partially offset by an increase of $333,000 in swap income. The increase compared to the prior year quarter was primarily due to increases of $333,000 in swap income, $65,000 in bank-owned life insurance income, $37,000 in fees and service charges and $9,000 in gains on the sale of loans, partially offset by a $113,000 decrease in gains on the sale of securities.

Noninterest expense of $9.0 million for the current quarter increased $151,000 compared to the linked quarter and $384,000 compared to the prior year quarter. The increase compared to the linked quarter was primarily due to increased professional, occupancy and data processing costs, partially offset by lower salary and benefits expense. Noninterest expenses increased compared to the prior year quarter primarily due to higher salaries and benefits and professional costs which were partially offset by lower pension costs.

The effective income tax rate was 21.0% for the current quarter, as compared to 20.4% for the linked quarter and 21.1% for the prior year quarter.

Balance Sheet Summary

Total assets increased $109.6 million to $1.98 billion at March 31, 2022 as compared to June 30, 2021, due to increases of $56.4 million in net loans receivable and $53.1 million in investment securities. Net loans receivable increased $56.4 million, or 4.6%, and $89.6 million or 7.5% excluding PPP loans. The increase was primarily the result of increases in commercial mortgage loans and construction loans of $70.8 million and $6.7 million, respectively, partially offset by decreases in commercial loans and residential mortgage loans of $9.2 million and $8.9 million, respectively. The decrease in commercial loans includes a decrease in PPP loans of $32.3 million, driven by forgiveness and paydowns, largely offset by a net increase of $23.0 million in all other commercial loans. The increase in investment securities was the result of the Company deploying excess liquidity and included increases of $28.2 million in state and municipal securities, $15.2 million in mortgage-backed securities, $5.3 million in corporate securities and $4.4 million in U.S. government and agency bonds.

Total liabilities increased $107.8 million to $1.71 billion at March 31, 2022 as compared to June 30, 2021 as an increase of $133.0 million in deposits was partially offset by decreases of $17.6 million in FHLB advances and $7.7 million in all other liabilities. The $133.0 million increase in deposits includes increases in money market, NOW, savings and demand accounts of $63.5 million, $44.2 million, $30.4 million and $24.8 million, respectively, partially offset by decreases in time deposits of $29.9 million. Current quarter deposit growth of $101.7 million or 6.7% includes approximately $38.1 million of transient deposits expected to outflow in the subsequent quarter.

Total shareholders’ equity increased $1.8 million to $276.4 million at March 31, 2022 as compared to $274.6 million as of June 30, 2021. The increase for the nine months ended March 31, 2022 was primarily due to net income of $11.4 million and $3.8 million of stock-based compensation and reduction in unearned ESOP shares for plan shares earned during the period, partially offset by the repurchase of $8.2 million (443,788 shares) of common stock, $2.5 million of other comprehensive losses related primarily to unrealized losses on investment securities driven by higher market interest rates and $2.6 million of cash dividends declared and paid.

At March 31, 2022, the Company’s book value per share and tangible book value per share were $18.02 and $17.62, respectively, compared to $17.41 and $17.01, respectively, at June 30, 2021. Reconciliations of book value per share (GAAP measure) to tangible book value per share (non-GAAP measure) appear at the end of this release. At March 31, 2022, the Bank was considered “well capitalized” under applicable regulatory guidelines.
